The present invention relates to forestry, in particular to the means for processing soil microphonescanine on the cuts when carrying out reforestation work.

In the practice of reforestation work on proscaronline felling and in conditions of temporary humidification-known technology of the plantation intermittent micropolishing. For this purpose apply the tillage device with different working bodies. However, they do not provide the necessary quality of micropolishing.

In the practice of reforestation works of the famous Ripper forest RL-1.8 [1, p.109-110], which includes a frame, a shaft with double-sided mounting brackets, operating parts (teeth), two supporting wheels with lugs and semi-circular grooves, the locking and unlocking mechanisms.

The disadvantage of the Ripper are omissions in the work at the meeting supporting wheels with obstacles (stumps, logging debris, stones).

Closest to the claimed device to the technical essence is intermittent borodoobraznymi [2], which allows us to generate intermittent micropipeline adopted for the prototype. The device includes a frame, a blade turntable, locking device and the mechanism of inclusion installed on the frame.

The disadvantage of the prototype is the impossibility of forming an intermittent the East micropolishing in the form of upturned strata of soil on the cuts due to structural features.

Rigid attachment of the blades of the vane causes the next working cycle. When dialing a prism drawing soils blade turntable does not rotate because it is fixed by a locking device. Nemognatha the blade shape and the mode of its operation (greater cutting angle) do not provide the cutting action of the soil. The result is scrivanie soil and the formation of a prism drawing. The rotating blade of the pinwheel starts after the triggering mechanism of inclusion. Prism drawing dialed. The rotation occurs until it touches the soil, the next blade. To continue the work necessary to turn the chopper blade in order to raise the blade, which is finished, otherwise it will ruin it created Metropolitana. At idle rotation of the cutting angle increases, which does not allow to deepen the working body and to form Metropolitana in the form of upturned soil layer in terms of logging.

To eliminate these disadvantages of the task was to improve the efficiency of the device in terms of deforestation and the quality of the generated micropolishing.

The proposed apparatus for forming an intermittent micropolishing. It includes a frame, an associated impeller vane, the locking mechanism and the mechanism of its turn, mounted on the frame. The difference is that the blades of the pinwheel Vogue is utie and fixed thereto movably, when this locking mechanism is installed on the impeller vane for each blade, and in addition the device is equipped with a free wheel mechanism connecting the frame and blade spinner. The locking mechanism is equivalent by function shut-off device prototype.

The elastic mounting of the blades on the impeller vane offer allows the device to perform a work cycle in which there is no idle rotation. At that moment, when the front blade will occupy a working position, the blade, completed the creation of micropipeline becomes mobile (the locking mechanism is deactivated). This allows you to save the generated Metropolitana and immediately (without idle rotation of the impeller vane) to start creating the next. With the rear angle and angle of cut can be set to a minimum, which reduces cutting force and allows you to create micropipeline in a wider range of soil conditions. Because idling blade chopper is missing, the center of gravity of the device during the cutting of the soil is shifted back in the direction from the fulcrum. As a result, vane vane creates a braking torque, which is sufficient for the formation of micropipeline. In order bladed spinner is not turned under the effect of this braking torque, the device supplying the but the free-wheeling mechanism.

For explanations of the described device figure 1 shows a diagram of the device, figure 2 - diagram of the forces acting on the device during the formation of intermittent micropolishing.

The device includes a frame 1, a blade spinner 2, locking mechanisms 3, the mechanism of inclusion 4, the free wheel mechanism 5, the blade 6, the elastic mounting of the blades 7 (figure 1).

The device operates as follows. Front blade 6 (figure 1), located in the working position, cuts the soil layer. During this period, the blade is fixedly mounted on the blade turntable 2. This consolidation provides a locking mechanism 3. When cutting layer blade turntable does not rotate. The free wheel mechanism 5 connecting the impeller vane 2 to the frame 1, prevents the rotation of the vane of the vane 2 in the clockwise direction against the direction of movement of the device). The turning vane of a vane counterclockwise (in the direction of movement of the device (V) prevents the moment of couple of forces from the action of gravity mg device and the support reaction R (figure 2), resulting from displacement of the center of gravity of the device About the pivot point, And the front blade. Due to the thrust P of the traction means attached to the frame 1, is cut layer with the depth of the blade. The depth continues up until the moment of couple of forces from the action of cutting forces R_p the thrust force P will not exceed the moment of couple of forces from the action of gravity mg device and the support reaction R. When the moment of couple of forces from the action of cutting forces P_pthe thrust force P exceeds the moment of couple of forces from the action of gravity mg device and the support reaction R, the cutting layer with the depth of the blade ends, and is turning vane of a vane. When this occurs, the circulation is cut out of the reservoir and its clamp to the soil. The blade still fixed on the blade turntable 2. The formation of micropipeline ends when the next blade will take position. At this point, the mechanism works include 4, and the locking mechanism 3 is turned off. The elastic mounting of the blade 7 provides the deviation of the blade when interacting with the created micropolitan. Metropolitana not destroyed and is pressed against the surface of the soil. Then support becomes the next blade begins to cut the soil layer, and the process of creating micropipeline repeated.

Upon further rotation of the blade of the chopper mechanism to enable 4 fires and includes a locking mechanism 3, which provides a fixed fastening of the blades on the paddle vane in position. At this duty cycle for the blade ends.

Thus, the new layout and interconnection mechanisms is s proposed device makes it possible to achieve the task.

Specifically, the device may be made in the following form. The frame has a standard fixture for connection to a towing vehicle and a site for attachment of the working body [1, p.42-60, 86-96]. Mounted on the frame of the mechanism of a free motion made, for example, in the form of a ratcheting mechanism [3], the output level is fixed bladed chopper. The elastic mounting of the blades is made in the form of a hinge. Working part of the blade is made concave, for example, similar to the bulldozer blade [1, str-245], which enables the cutting of the soil simultaneously with depth. The mechanism of inclusion connected with the frame and is made, for example, in the form of a copier like raskryvali tree-planting machines [4]. The locking mechanism is made, for example, in the form of a lever mounted on each blade, similar to the levers, mounted on the gripper beam planting tree-planting machines machines [4]. The lever interacts with the mechanism of inclusion (copier) and fixation of the blades on the impeller vane.

The mechanisms proposed device used is known technical solutions: frame, freewheel mechanism, the elastic mounting of the blades, concave blades, mechanism of activation and shut-off mechanism [1, 3, 4], which perform specific functions. To implement these functions can be IP is alsomany and other known technical solutions, similar to them. The achieved result and the operation of the device provide a new layout and the relationship (interaction) of these mechanisms.

In science and technology reforestation of the known device, comprising part of the essential features we offer: apparatus for forming an intermittent micropolishing [5], which includes a frame installed through the horizontal axis of the blade spinner with curved blades, the mechanism of inclusion, in addition, this known device is provided with a brake, a machine for education in soil wells, including movably mounted on the wheel working bodies stop their swing [6]. Bringing these essential features of the proposed device does not provide the necessary information to solve the problem of the interrelation mechanisms.

The lack of information on the application of the known mechanisms in the proposed layout and interconnections to implement the tasks, as well as the obviousness of the proposed solution for professionals on the basis of prior art, allow to draw a conclusion about conformity of the present invention, the criteria of “novelty” and “inventive step”.

The application of the proposed device to the known species of forest works allows you to recognize the invention p is umyshlenno applicable.

The efficiency of the device in terms of deforestation and the high quality of the generated micropolishing tested in practice. Photos: figure 3 - the device in the transport position; figure 4 is formed micropipeline and work on cutting. The size of micropolishing were: height - 26 cm, length 75 cm, width 95 see the performance of the device in Assembly with a tractor LGT-55 amounted to 900 micropolishing per hour.
