Description

The invention relates to agricultural machinery, in particular to the shredder of m-mixers of heterogeneous viscous liquids, for example, wastewater from livestock farms and complexes during their unloading, mainly from small-scale storage facilities.

The purpose of the invention is to increase the operational reliability by allowing the rotational speed of the mixing blades to be equalized at start-up and to increase their moment of inertia.

FIG. 1 schematically shows a chopper-mixer of inhomogeneous liquids, a general view; in fig. 2 is the same, view A in FIG.

The grinder-mixer contains a frame 1, on top of which is mounted a flange electric motor 2 and a vertical drive shaft 3 connected to it with longitudinal guides 4, on which hollow mixing blades 5 are mounted for movement along the shaft, equipped with grinding devices on the back part of rotation. .

Each floor of the mixing blade is divided inside by a transverse partition 7 into two separate chambers — an internal chamber 8 and a peripheral chamber 9, communicating with each other by means of bypass calibrated holes 10 and 11, made respectively in the upper and lower parts of the partition, and a check valve 12 installed in the lower part of the partition and opening in the direction of the chamber 8. In this case, the chamber 9 is placed at a higher level and its bottom is located with a slope to the bottom of the chamber 8, the cavity of each blade is placed Chii svobodnoteku- divided mass, preferably high density material, such as mercury, mineral oil, water and other liquids or free flowing solid materials - quartz sand, hunting shot, smaller beads, etc.

In the upper part of the manure collector, in its overlap, there is an intake hatch 13 for suctioning qualitatively mixed and ground non-uniform liquid with transport and technological means. Mixing blades are installed in the tank 14.

Grinder-mixer works as follows.

In the quiescent process, the mixing blades 5, when the level of the manure mixed in the tank 14 fluctuates, will constantly descend or float, moving along the guides 4 along the vertical drive shaft 3.

When the motor 2 is turned on, the drive shaft rotates and, with it, the agitator blades mounted on it with the help of guides.

In the course of work, the grinding devices are inserted into the mass of manure processed and the grinding of the long fibrous and large particles of feed waste, random objects that form a dense layer floating on the surface of the manure collector, is made.

Mixing blades with grinding devices during rotation work on the principle of the propeller. At the same time, the guides 4 of the shaft 3 operate on the principle of a mechanical paddle stirrer, creating discharge along the shaft, allowing air to be sucked into the tank throughout the depth and to saturate manure with them to enhance the oxidative processes in it.

When starting the grinder-mixer into operation, the liquid or bulk material with which the chambers 8 of the blades 5 are filled, under the action of centrifugal forces, moves through the lower holes 11 of the transverse partitions 7 and is thrown into the chambers 9, fill them and force air out of them through the upper holes 10 of the partitions. chambers 8. At this time, check valves 12

due to the pressure on them from the side of the chambers 8 are closed,

When the grinder is stopped, the liquid or bulk material moves from chambers 9 back to chambers 8 through

the lower orifices 11 and valves 12, which are automatically opened under the action of the static pressure of the liquid column in the chambers 9, facilitate a more rapid return of the liquid or material back to

camera 8 to its original position. At this time, the air from the chambers 8 through the upper orifices 10 is forced into the chambers 9.

This interaction of fluid and air occurs every time the cycles of starting and stopping the rotary system of the grinder-mixer are repeated.

As a result, the centers of gravity of the blades are shifted from the center to the periphery. In this case, the inertia of the rotating system increases and the torque and speed of rotation of the drive shaft are equalized, which is especially important when the mixing paddles interact with solid inclusions and
