Abstract

FIELD: agriculture.

SUBSTANCE: invention is related to agriculture, veterinary medicine, in particular to devices and accessories, which provide for removal of excess horn on hoofs and sharp ends of horn shells. Device comprises body-handle, shaft installed in bearings in body-handle, cutting apparatus in the form of disk cutter and support disk with sector cut arranged at the end of shaft, drive. In body-handle there is electric motor arranged, shaft of which is installed in bearings of supports, which bears turbine-wind blower, passes in slide bushes of supports and ends with disk cutter. Disk cutter has figure teeth arranged along its periphery. Turbine-wind blower supplies flow of cooling air to disk cutter and in area of horn and bone masses through perforations provided in body-handle, supports of bearing and supports of bushes. In section of body-handle, which is adjacent to disk cutter, there is a threaded section, where threaded section of support disk may move and be fixed in required place with lock-nut.

EFFECT: application of invention makes it possible to increase efficiency and safety of labor in prophylaxis and treatment of cattle orthopaedic diseases.

Description

The present invention relates to veterinary medicine, specifically to devices and appliances that remove excess horn on the hooves and the sharp ends of the horn covers.

Cattle belong to the order of artiodactyl animals. In each hoof, the outer and inner walls, the sole are distinguished. The work of many domestic and foreign scientists proved that the horn of the wall of the hooves monthly lengthens by 6-10 cm. Under grazing conditions, when animals search for food for quite long walks on virgin soil, the horn erases to the extent that it is produced. Therefore, in these animals, deformed and pathological hooves are rarely observed [1, 7].

With industrial methods of keeping, when animal walks are minimized, the growing horn accumulates, the hoof wall moves away from the sole and takes on the weight of the animal. It stagnates, his appetite decreases, the amount of feed taken decreases, productivity decreases, live weight [2, 5].

According to USSR author's certificate No. 893194 dated 12/30/1981 (6), a device is known for trimming horn and bone formations in animals, having an electric drive connected by a flexible shaft in a carapace with a shaft of a device mounted on bearings of the handle body carrying a disk cutter at the end having a non-removable support disk with a sector cut.

The purpose of the invention is to increase productivity and operator comfort, reducing pain and anxiety of the animal during the operation.

This goal is achieved by the fact that the electric motor is mounted in the handle housing, the shaft of which is mounted on the bearings of the bearings, carries a wind turbine, passes in the sliding bushes of the bearings and ends with a disk mill having curly teeth mounted around its periphery, and the wind turbine supplies a cooling flow air to the disk cutter and to the incision site of the horn and bone formations through perforations made in the handle body, bearings and bearings of the perforation bushings, while on the handle body portion adjacent to the disk cutter Furthermore, there is a threaded section along which the threaded section of the support disk can be moved and fixed in the right place with a lock nut.

The device is schematically shown in section with a disk mill in figure 1, figure 2 schematically shows the same and convex disk mill, bearing on the front surface of the notch, removing during rotation of the horn.

The device has a handle body 1 made of dielectric, perforation 2, a threaded section 3, a lock nut 4 provided with the same thread as the handle body, a support disk 5 with a sector cut, equipped with the same thread as section 3.

In the handle housing 1 there is an electric motor 6 with an extension cable 7, a tumbler 7 "a", an electric plug 8. The shaft 9 of the electric motor 6 is mounted on bearings 10 of the bearings 11 with perforations 12, carries a wind turbine 13, passes in the sliding bushings of the bearings 14 provided perforations 15, ends at the end of the disk milling cutter 16, bearing around the periphery of the curly teeth 17.

Figure 2 shows a disk mill with a flat and convex front surface, bearing on the periphery curly teeth 17, and on the front surfaces of the notch 18 with holes 19.

The operation of the device: inspect on the fixed limb of the animal hoof, determine the order of work. Operations to remove the excessive horn of the walls of the hooves are performed by a disk cutter 16 with curly teeth 17 on the periphery. They take the handle-housing 1 in their hand, the lock nut 4 and the support disk 5 are displaced along the thread of section 3 to the desired distance from the lower surface of the disk cutter 16, fix the support disk 5 with the lock nut 4, turn on the power plug 8 of the power cable 7 to the power source socket, and place the plantar surface of the hoof wall on the free part of the support disk 5, include a toggle switch 7 "a" electric motor 6 in the work. After that, its shaft 9 begins to rotate in the bearings 10 of the bearings 11 and in the sliding bushes of the bearings 14, the rotating wind turbine draws air through the perforations 2 and 12 and drives it through the perforations 15 under the lower surface of the disk mill 16. Its cutting edge with curly teeth 17 lead to the wall of the hoof and saw it to a depth specified by the supporting disk 5. At the same time, the incoming high-speed air stream cools the working part of the disk cutter 16 and the horn of the hoof in the cut part, reducing the pain of the operation, blowing out the horn sawdust, facilitates its implementation by the operator.

If necessary, remove the excess horn of the inner wall of the hoof or the sharp end of the horn cover using a sector cutout of the supporting disk 5.

To remove the excess horn of the sole, the hooves use a disk cutter with a convex or even front surface, equipped with notches 18 and holes 19 around them.

We believe that for the prevention and treatment of diseases of the fingers and distal (lower) parts of the extremities that arise as a result of deformation of the hooves due to the accumulation of excess horn, the device will be widely used in veterinary medicine, in farmers and other farms.
