Features of the prototype.
The hydraulic working body has not horizontal rotating shaft and the rotating body, which is fixed to the rippers, making a circular motion in a vertical plane. The mixer has a shape of a trapezoid and rectangular (or oval) inlet, the longest side parallel to the bottom area. Hydraulic motor with rippers placed in the casing for the protection of water from pollution by products of loosening. Rippers offers products loosening to the inlet of the mixer, and the existing in the slurry line pull flow, caused by the difference of the ordinates of the location of the mixer and the underwater vessel, must involve these foods in the mixer and transport them to the underwater vessel. From this vessel the slurry is pumped mud pump on the barge.
The disadvantages of the prototype.
With hand mixer cover does not cover the actuator, and the products loosening dissipate as past of the mixer and through the lower slots on three sides of the casing, polluting the waters.
- As products of loosening not fall in full at the inlet of the mixer and not enabled the feature of monitoring the condition of the bottom and the process of protozanova, the performance of the prototype reduced.
Thus, the prototype has a low ecological protection areas and performance protozanova that is his shortcomings.
The technical result of the invention is to remedy these disadvantages, i.e. increasing environmental protection areas and performance suction head; it.
The technical result is achieved in that the housing of the working body is made of cylindrical form, mounted vertically and connected rigidly to the upper end with the slurry line and the bottom end is with a mixer, which is in the form confuser with input in the form of a circle, the actuator of the working body is built in concentric cavity of the casing and rigidly connected with him radial ribs with the formation of the annular flow channel, rippers mounted on the shaft of the hydraulic motor of the working body with the possibility of circular motion in a horizontal plane, and the bracket has two hinges and two hydraulic cylinders for movement of the working body in the vertical and horizontal planes, in addition, self-propelled the trolley there is a cabin with a porthole, a headlight and a separate power source, which is communicated to the air channel with the atmosphere of the underwater vessel, and the oil station with pump and water-cooled engines is eaten is located inside the cabin, the water outlet from the water engine is in communication with the underwater vessel an additional channel, and the pressure and drains the hydraulic drive working body in a radial ribs connecting the actuator with its casing.
With this device you can cover with mixer entire area of loosening hard ground and uniformly on the circular contour of the mixer into the slurry line flow of water concretions and silts, not throwing them in the water, is improving the environment and improving the performance of protozanova. In addition, when the fixed self-propelled cart working body according to the invention it is possible to move in an arc, occasionally lifting it increases the area of processing of the bottom without resuspension and this measure helps to improve the environment and increase productivity protozanova.
With a constant source of hydroelectric power, corresponding to a pressure differential due to the difference of the ordinates of the location of the mixer and the underwater vessel, you can increase the power of the water engine oil-pumping stations, therefore, to increase the volumetric capacity of the hydraulic motor of the working body. The increase in the driving time of the last accomplished by increasing the axial size of the gate with a minimum diameter of three-dimensional hydraulic motor, which increases speed and thrust) of the flow in the area, this is the first hydraulic motor, i.e. to increase productivity suction head; it.
Comparison of the claimed features of the technical solution with the prototype allowed us to establish compliance with the criteria of "novelty" and "essential features".

The inventive device may be provided with a volumetric hydraulic motor 21 of the working body 10, for example, patent RU No. 2295062 that allows you to implement a high driving torque on a shaft 22 through the axial length of the gate 30 at a sufficiently high level of kinetic energy in the mixer 20 and the annular flow channel 28. The performance of the suction head; it increases.
Unlike the prototype, where the nutrition water hydraulic working body made from additional pump (located in the vessel 3) additional channel, in the inventive device volumetric hydraulic motor 21 of the working body 10 is fed from the oil pump 34 in the cab 7, and the water engine 6 of the pump are powered by outboard water directly and uses the difference H=Z1-Z2equal to the depth of the underwater vessel 3, and the exhaust in the engine water is returned in the additional channel 14 in underwater vessel 3. Who is Rath water via a flow path of the slurry line 12 (as the first analogue and prototype) unreliable because filled with nodules and silt slurry line can be stopped and the oil station at this time should work. The reliability of the inventive suction head; it increases the process control system of protozanova simplified - this is an additional advantage of the inventive device.
The composition of the suction head; it is the prototype for the patent RU No. 2112139 - includes slurry line 12, the mixer 20, the casing 26, the volume of the hydraulic motor 21 with the shaft 22 and the rippers 25 forming the working body 10, which is connected by a bracket 11 with additionally installed self-propelled carriage 5, and the slurry line 12 is hydraulically communicated with installed underwater vessel 3, in turn communicated with the atmospheric pressure, and the oil station 35, as further known from the first analog element.
Unlike the prototype casing 26 of the claimed device is made of cylindrical form, mounted vertically and connected rigidly to the upper end with a slurry line 12 and the bottom with a mixer 20; the latter is in the form of a confuser with a circular entrance radius RC.
This volumetric hydraulic motor 21 is embedded concentrically in the hollow casing 26. It is rigidly connected to the casing radial ribs 27 through outlet ports 32 in which the working chamber 24 is fed to the working liquid is from the pump 34.

Mounted on the shaft 22 rippers 25 make a circular movement in a horizontal plane during rotation of the shaft and break the continuity of the cortical formations bottom.
The bracket 11 has two hinges 15, 16 and two hydraulic cylinders 8, 9. This measure makes it possible to move the working body 10 in the vertical and horizontal planes. On self-propelled trolley 5 is installed cabin 7, which is communicated to the air channel 13 with the air environment of the underwater vessel 3 with atmospheric pressure and includes an oil pump 34 with a water motor 6. This engine works by differential head H=Z1-Z2due to the difference of the ordinates of the position of the self-propelled truck 5 and the underwater vessel 3. Evacuation of spent water from the water motor 6 is carried out by the drain to let the water 14, which is connected to an underwater vessel 3.
The work of the suction head; it is in the composition of the Maritime industry.
Include water engine 6 - powered oil pump 34 of the pumping station 35. This engine is perpetuated differential head H=Z1-Z2; spent in the engine water is evacuated until the Alu 14 in underwater vessel 3. After exploring through the window 17 of the fundus illuminated by the headlight 18 include volumetric hydraulic motor 21 and with the help of hydraulic cylinders 8, 9 is lowered working body 10 in the right place - rippers 25 break cortical education. Open the stop valve on the slurry line 12 (located in the vessel 3; not shown) creates a transport stream water (thirst), directed upwards through the mixer 20 with the input section, annular channel 28 sectionand the cavity of the slurry line 12 with its end in the vessel 3, in which there is an air of atmospheric pressure pand. Created by the pull of the thread sucks hard pieces of bottom rocks and on the principle of hydraulic lift transports them into the specified container.
The destruction of the bottom of the rocks occurs under the hood, which is the casing 26 with a mixer 20, and the suction of the water takes place by the circular mixer circuit of radius RCthrough the gap left by the driver in the lowering of the body. Dispersion roiled bottom surface of the cap beyond mixer no - this is the positive environmental effect of the present invention.
The working volume of the hydraulic motor 21 figure 3: oil under pressure enters the working chamber 24 through the discharge channels 32 in a radial ribs 27 rigidly mounted on the housing 23. Pressed to the spring case Tiber 30 sees oil pressure - occurs torque on the shaft 22. Diverters 29 divide the working chamber into two parts, in each of which the gate is out of the whipstock, reports on the shaft torque, displaces the oil in the channel 33 and is formed below the whipstock. The frequency of rotation of the shaft 22 depends on the displacement of the hydraulic motor 21 and the pump 34, which may be regulated. To increase torque can be ceteris paribus increase of the axial length of the working chamber 24 (gates 30).
After processing the first plotlift hydraulic cylinder 9 working body 10 above the bottom due to the presence of the hinge 15 on the bracket 11 with the hydraulic cylinder 8 and the hinge 16 turn the working body in the right place. Then work the lower body, and the process of protozanova repeats. The possibility of inspection of the lighted lamp 18 of the bottom through the window 17 and the choice of fence nodules from one position of the truck (without resuspension of the bottom of the truck), and the coverage radius of the larger bottom area increase device performance and environmental protection area.
From the underwater vessel 3 the pulp is pumped to the barge 1 mud pump on top of the slurry line 2. Changing the position of the self-propelled truck with 5 cabin 7 and with a raised working body 10 is using hydraulic motors 19. The control valves is of gidrodvigatelya and cylinders, and cabin lighting 7 and the bottom of the headlight 18 is running on battery power. Maintaining atmospheric pressure in the cabin is air channel 13. Lifting the bottom of the equipment for change of crew, charging batteries, running repairs, etc. is performed by means of the cable 4, and the mouth of the cab 7 is drawn into the receiver vessel 3.
Thus, made improvements provided performance suction head; it is in the improvement of environmental safety and performance protozanova.
