The technical solution relates to mining, namely heavy (carrying more than 40 tons) of cargo transport machines for underground and opencast mining operations.

Known handling machine of this class (see Tikhonov NV, Rysev G.S. Shaft loading-transport machines. - M.: Nedra, 1976, p.122), which consists of the power plant, running gear on pneumocandin wheels, cargo body, which consists of the bucket, boom and hydraulic control. The front part of the chassis is busy loading body, rear mounted diesel drive with a catalytic Converter, the exhaust gases. Buckets of these powerful machines with static teeth, in the process of loading lumpy rock mass have significant resistance, preventing the introduction of the bucket into the pile. The solution to this problem by increasing the capacity and accordingly the mass of the machine leads to increased energy consumption for loading rocks and reduction of specific performance of the machine.

Closest to the proposed technical solution to the technical nature and essential features is handling machine (see French patent No. 2323825, E 02 F 5/30, 3/36, priority from 9.09.1975), which consists of power unit, chassis, loading shovel, the front wall of which is to reduce the soprotivlenie implementation of the working body in trudnorazreshimym, including krupnokuskovoy material, equipped with shock teeth located on the entire working edge having a rectangular shape. As sources of shock pulses are pneumatic or hydraulic percussion device mounted on the front wall of the bucket and functioning independently of each other. The rear wall of the bucket is at an angle to the front wall close to straight. According to this invention the bucket produces simultaneously crushing and loading rock in a short period of time the same machine.

The disadvantages of the known designs include the following. The process of bailing rock bucket loading machine includes: implementation of the bucket into the pile of rocks on the maximum possible depth and filling it with turn arrows loading machine. Therefore, the efficiency of filling of the bucket, and hence the completeness of the use of its useful capacity largely depends on the embedding depth of the bucket into the pile.

The location of the rear wall of the bucket is known loading machine at an angle to the front wall, close to direct that allows more or less freely bury bucket only on the length of the front wall, further implementation is associated with a sharp increase in resistance caused by the crushing of rock in the rear walls of the second bucket. Bucket with a rectilinear shape of the working edge, as practice shows, is experiencing a lot of resistance when embedded in a pile of rocks.

Shock teeth in the bucket of this machine are located along its working edge. The greater the width of the bucket loading machines, and it has heavy vehicles reaches 4÷5 m, the greater the number of teeth of the working edge and shock devices on the front wall of the bucket must be installed, and therefore, requires additional power for their gear. This leads to increased size and weight of the machine, thus reducing its specific mass number mass of rock in the bucket to the machine's weight is a measure of the perfection of the design loading and transport of the machine.

Thus, structural features of the known bucket loading machine: straight shape of the working edge of the bucket and the rear wall, which is located to the front wall at an angle close to the direct causes additional resistance to the introduction of the bucket, as well as the unsustainable location of the shock of the teeth on the working edge of the front wall reduces the efficiency of loading and transportation of the machine.

Technical problem - increasing the efficiency of loading and transportation of the machine by reducing resistance to the introduction of the bucket into a pile of rocks and the AK consequence, increasing the depth of the implementation and improvement of the useful capacity of the bucket.

The problem is solved in that in the handling machine, including loading the body consisting of a bucket with a shock teeth, arrows and cylinders control, daytime running engine and the propulsion unit, according to the technical solution of the front wall of the bucket is made with serving at the side wall part in the form of an isosceles triangle, or close to it forms at least 1/3 of its total length, and the working edge of the front wall of bucket form the equal sides of the triangle, percussion teeth mounted along the axis of the front wall, side walls and with step 3÷5 width percussion of the tooth while the rear wall of the bucket is made with an inclination relative to the front wall at an angle of more than 90°.

One of the important indicators of cargo transport vehicles is the specific gravity of the machine is the ratio of the weight of the rocks in the bucket to the total weight of this machine. The greater this ratio, the more efficient use of the useful capacity of the bucket, the more perfect the design of this vehicle. Such a machine for one cycle reaches the maximum filling of the bucket, which is proportional to the depth of implementation.

To increase the depth of implementation of the proposed technical re is drop the front wall of the bucket is made with serving at the side wall part in the form of an isosceles triangle, or close to it forms at least 1/3 of its total length. This form protruding part of the front wall of the bucket allows you to increase the force introduction axis, and the first stage of penetration to avoid contact of the side walls with the stack, thereby reducing drag and increasing the depth of implementation and, consequently, to improve the filling of the bucket, i.e. more efficient use of its capacity.

Install the shock of teeth along the axis of the front wall, side walls and with step 3÷5 width percussion of the tooth, compared to the prototype, allows, firstly, to reduce the number of shock teeth in the bucket, secondly, to concentrate them in the parts bucket with the greatest resistance during its implementation, i.e. thereby more effectively use applied to the ladle energy. In addition, the shock teeth installed in locations pairing of the front wall of the bucket side walls, raising them in fluctuations, reduce the friction force of the rocks on the side walls, reducing their resistance to the implementation.

The step between the impact teeth is selected depending on the size of pieces of rocks within 3÷5 width percussion of the tooth. This arrangement of shock teeth on the front wall of the bucket reduces the installed capacity of their drive, the total weight of this vehicle, thereby improving an important indicator of the effectiveness of the machine CA is the specific gravity of the machine.

The location of the rear wall of the bucket to the front at an angle of more than 90° reduces, in comparison with the prototype, the displacement resistance of the rocks in the bucket, contribute to a better filling of the latter, thereby increasing the efficiency of use of the useful capacity of the bucket.

Thus, the application of the proposed solution reduces the resistance to the introduction of the bucket into a pile of rocks and, as a consequence, increases the depth of penetration, improves the utilization of the useful capacity of the bucket, improves the performance of loading and transportation of the machine.

It is advisable on the front wall of the bucket loading and transport of the machine between the impact teeth to fix the static teeth. In operation, the bucket drums teeth, interacting with each other, create around themselves a disturbed area greater than the dimensions of the tooth. Therefore, the shock teeth should be installed on the front wall of the bucket, as noted above, depending on the size of rocks with a certain step, and between them a static teeth that work well in a broken shock teeth area, increasing the efficiency of the machine.

It is advisable to equip the rear wall of the bucket with a vibrator. Forced vibrations generated by the vibrator in the back, reduce the resistance to movement of rocks vawse, improve its content.

It is advisable that in the loading position of the bucket angle between the rear wall and the horizontal plane does not exceed the angle of internal friction of rock. This reduces friction in the process of moving rocks in the bucket, reducing the force introduction into the pile, improves the filling of a bucket, increases the efficiency of use of its useful capacity.

It is reasonable to provide cargo transport vehicle battery energy of the drive drum of the teeth of the bucket. Implementation time bucket per cycle decreased during which should run continuously shock the teeth varies in the range of 3÷5 that is not more than 10% of the total duration of loading-transport cycle of this vehicle when the length of the haulage 100 m Battery is filled with fuel - air or liquid (depending on the drive type shock teeth) during transportation of rocks, when the actuator loading and transport of the machine is less busy. The presence of the battery (air or liquid receivers) for accumulation of energy allows the use of a compressor or oil-pumping station lower productivity and hence lower power consumption no less than 10 times that, in turn, reduces the total weight of this vehicle.

It is advisable the ri output of the specified accumulator to set the control parameters of the energy source drive shock teeth, which allows to ensure the stable operation of this drive.

The reduction of the installed capacity and the increase of the specific mass loading and transport of the machine is achieved, on the one hand, by reducing the amount of shock teeth mounted on the front wall of the bucket, on the other hand, due to the use of battery energy, reduce several times the capacity of the drive drum teeth. Reduction of installed capacity reduces the total weight of the proposed machine.

The essence of the technical solution is illustrated by a specific example and the drawings, in which figure 1 shows handling machine, side view; figure 2 is a top view.

The driving force of the engine 2, the bucket of the working edge 10 of its front wall 6, are equipped with drums 11 and 12 static teeth, rests on the base of the pile under the action of the reactive forces of the shock teeth 11 are included in the work, begins the process of implementation of the bucket into the pile and filling rock. After filling the bucket with hydraulic cylinders 5 control arrow 4 lifts the bucket to transport provisions included driving mechanism 2 and the machine goes to the place of unloading. After unloading the machine is returned to the stack, the bucket again is the source for the azerbijani position. Then the cycle repeats.

Implementation time bucket in the stack is, as noted above, no more than 3÷5 C. the Time of transportation depends on the speed of movement of the machine and the distance to the point of unloading, which varies from 50÷300 m During this time, and it is an average of up to 80÷90% of the length of the entire cargo transport cycle is charging the battery 14 energy source.
