Description

FIELD OF THE INVENTION The invention relates to agriculture, in particular to devices for clearing hoofs.

The purpose of the invention is to improve the quality of cleaning and prevent injury to the hoofs during their cleaning.

FIG. 1 shows a hoof trimmer, plan view; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows a section BB in FIG. one.

A hoof trimmer mounted on a hoisting platform consists of tanks 1 and 2, made in monolithic concrete and placed one behind the other. The container 1 is separated from the container 2 by a concrete bridge 3. At the edges of containers 1 and 2, metal rods are fixed horizontally, at a certain interval, which form a support for the legs of the animal in the form of a lattice 4. The rods are arranged so that their side surface is perpendicular to the direction of movement treated animal (Fig. 1, arrow B).

The depth of each tank is not the same everywhere. Capacity 1 has a greater depth at the left side of the animal in the direction of movement of the animal, and capacity 2 - at the right (Fig. 2). In the longitudinal axis of the device, the depth of the containers 1 and 2 gradually increases from its peripheral part to the bridge 3. Both containers in the lower side part at the maximum depth have a collecting channel 5 of cylindrical shape (Fig. 2 and 3).

On the side surfaces of the containers 1 and 2 are mounted on supports (not shown), bunkers 6 for abrasive material, with the bunker 6 installed above the container 1 located on the right side along the movement of the animal side being processed, and the bunker installed above the container 2 nd left . The bunker is made of sheet steel and has the shape of a cone, the top of which

directed to the supporting surface of the device (Fig. 2). At the apex of the cone (in the lower part of the bunker) there are outlet slots 7 (Fig. 2), which are arranged so that the slot of each of the windows is between the rods 4 of the support surface of the device,

In the lower part of the bunker there is a horizontal feeder shaft 8 with blades 9 fixed on it. The blades are fixed on it in the radial direction so that the slot of the windows is covered (Fig. 2). The shaft is supported on rolling bearings 10, which are fixed on the sides of the bunker 6. The drive shaft 8 is driven from a drive station, which consists of an electric motor 11, which is connected to the input shaft of the gearbox 13 by means of the coupling 12. The output shaft of the gearbox 13 is connected by the coupling 14 with a shaft-feeder 8. On the shaft there is an asterisk 15, which is connected via a chain 16 with an asterisk 17 mounted on the input shaft of the gearbox 18 installed in the upper part of the hopper 6, on its side wall (FIG. 1). The output shaft of the gearbox 18 is connected via a cardan drive 19 to the shaft of the inclined screw conveyor 20. The inclined screw conveyor has a cylindrical case 21 (FIG. 3) and is parallel to the direction of movement of the animal being treated so that its upper part is above the hopper 6 mounted on the side surface tank 2, and the lower part - in the lower part of the tank 1, in the zone of the collective cylindrical channel 5 (Fig. 1 and 3). Another screw conveyor 20 is installed so that its upper part is fixed above the bunker b, installed on the side surface of the tank 1, and the lower part - at the lowest point of the tank 2, in the zone of the collecting cylindrical channel 5 (Fig. 1).

The hoof trimmer is equipped with a system for supplying fluid to containers 1 and 2. The system includes a container 22 for collecting carrier fluid, pumps 23-25, filters 26, distributors 27 and 28 liquids, outlets 29, pressure 30 and returnable 31 lines ( Fig. 1-3). The outlets 29 are made of horizontally arranged on the lateral surface of the containers 1 and 2 of circular tubes installed below the bars of the supporting surface and between them. The intake nozzle of the return line 31 is located in the upper part of the collecting cylindrical channel 5 (Fig. 2).

Along the grill 4, a fence 32 is installed, made of circular pipes. All the details of the device, except for the grid 4, form the working unit of action on

animal hooves.

The hoof trimmer operates as follows.

Both bunkers 6 are filled with abrasive bulk materials, for example, river beacon, and the tank 22 is filled with liquid, for example water. The pump 23 is turned on, which, via line 30 of the capacity 22, supplies fluid to the container 2. As the tank is filled, the pump 24 is turned on and after

5 of the tank 1 filled with liquid. The pump 25 is turned on. The drive of the shaft-feeder 8 is turned on. The rotating shaft captures a certain volume of abrasive material with its paddles 9 and directs it to the edge of the grid through the outlet slot 7 to the zone of action of the outlets 29. A water jet directed from issues 29, picks up the abrasive material and transports it along the bars of the bearing surface,

5 on which the animal is pounded.

The abrasive material transported by the fluid jet has some energy and with a certain effort it acts on the exfoliated old

0 horn, especially in the area of the carp mum. Under the influence of abrasive material, the old crumbling and flaking horn is removed from the surface of the claw, exposing the new hoof horn. Together with the old swarm, a stream of fluid carries away adhering soil, manure, from the surface of the hoofs. Abrasive material in a jet of fluid removes the old delaminated and crumbling hoof from all surfaces of the hoof: smooth and smooth. The jet carrying the abrasive material and reflecting from the side walls of the lattice support surface penetrates into the intergastric gap and cleans it. Abrasive material moving in

5 a stream of fluid polishes the surface of the hoof, the edge of cracks and scoring. The liquid is supplied to the tanks 1 and 2 so that it completely covers the rods 4 of the supporting surface.

0 Due to the fact that the containers 1 and 2 have not a constant depth, the smallest on the side of the outlets 29, as well as an inclination in the direction of the bridge 3, the movement of the fluid, and with it the abrasive material

5 is the same everywhere. In sprayers, the jet has a significant supply of energy and the movement of fluid with an abrasive material is carried out along the bars of the grid 4 of the bearing surface. On this site. the most intensive removal of the old hoof horn from the bottom and side of the claw occurs. In the middle part of the tank, where, due to an increase in its depth, the volume of the tank increases, the pressure of the jet with an abrasive moving between the rods is somewhat weakened, since part of the energy is already spent on transferring the abrasive material and overcoming the friction forces on the rods and hooves of the animal. As a result, the fluid stream is also affected by the movement of the lower fluid flows directed to the bridge 3. At the same time, the two fluid layers are mixed, which is characterized by the chaotic movement of the abrasive material. In this area, not only the support surface is cleared, but also the inter-digging cracks.

On the side opposite to the distributors, the containers 1 and 2 have the largest volume and the liquid head is minimal. Here the movement of the lower carrier layers prevails. Due to a decrease in the carrying capacity (minimization of the kinetic energy of the jet to a minimum), the abrasive material is lowered to the bottom of the tank and, under the influence of the lower layers moving towards the collecting channel 5, also moves to it, where it accumulates. The place of accumulation of abrasive material falls into the zone of action of the screw conveyor 20. The abrasive material picked up by the turns of the conveyor along the casing 21 is directed to the hopper 6. The cycle of movement of the abrasive material repeats.

It is possible to use abrasive material on a closed cycle for a rather long time, since it does not lose its abrasive properties for a long period of time. This is achieved by the fact that abrasive material is harder than the separated hoof horn or other components involved in the process. Therefore, the abrasive settles at the bottom, and all other components, as a result of mixing of the liquid layers, are in a chaotic motion in the bottom part of the tank. Pump 24 through the intake nozzle of the return line 31 this liquid is passed through the filter 26, where all the components are

In addition to the abrasive and the liquid itself, the particles remain on the filter elements, and the purified liquid is directed through the distributor 28 and the outlets 29 into the container 1. The abrasive material is fed from the hopper 6 of the container 1 to the newly formed stream.

Now the jet of liquid and the abrasive material moving in it, influences the other pair of the animal's limbs, similarly processes the bearing surface and the inter-pit slit, clearing them from the old hoofed horn.

The water from the tank 1 through the intake nozzle of the return line 31 by the pump 25 is directed through the filter into the collection tank 22. The cycle of the fluid movement is repeated.
