RU2270559C2 - Apparatus for removal of liquid and semi-liquid manure - Google Patents

Abstract

FIELD: agriculture.

SUBSTANCE: apparatus has spray deflecting shield, transportation devices, each made in the form flexible cylindrical screw with drive arranged at product discharge side. Transportation devices are located in longitudinal and transverse manure channels closed from the top with grids. Transportation devices are hung without contacting with channel bottom and walls for displacement along channel bottom. End of flexible cylindrical screw opposite to drive is attached to bearing support, which is adapted for axial displacement along screw for adjusting tension of transportation device.

EFFECT: reduced power consumption, decreased wear of transportation device and wider operational capabilities of apparatus.

Description

The invention relates to agriculture, in particular to devices for removing and unloading liquid, semi-liquid manure and litter, mainly from livestock and poultry facilities.

A device for removing liquid and semi-liquid manure containing transporting working bodies located in the longitudinal and transverse manure channels is known. The walls of the manure channels are made with alternating longitudinal strips of antifriction material and concrete, installed along the manure channels along the lines of contact with the working body. The manure channels are triangular in cross section and are closed on top by grilles. The working body is made in the form of a flexible cylindrical screw. The drive of the working body is placed on the discharge side of the product, and the drive shaft is passed through a splash shield [1].

The known device for removing manure from livestock buildings has a working body, the end of which is not fixed on the side opposite to the drive. The lengthening of the working body that occurs during operation of this device leads to oscillations of the working body, touching the walls and the bottom of the channel, which leads to an increase in the energy consumption of the process and wear of the working body. The design of the working body in this device does not allow moving the working body along the bottom of the canal, which is required when removing manure from rooms with dung channels that differ in shape from triangular, the width of which is greater than the external diameter of the working body.

The invention is aimed at reducing the energy intensity of the process, reducing wear of the working body and expanding the applicability of this device.

The specified technical result is achieved by the fact that the working body is suspended without touching the bottom and walls of the channel with the possibility of its movement along the bottom of the channel. The bearing support, to which the end of the flexible cylindrical screw is attached, opposite to the drive, is made with the possibility of movement along the axis of the screw to regulate the tension of the working body.

Figure 1 shows a General view of the device, figure 2 is a cross section of a longitudinal manure channel.

A device for removing liquid and semi-liquid manure from livestock buildings contains transporting working bodies 1 in the form of a flexible cylindrical screw with a drive 2 located on the discharge side of the product, placed in the longitudinal 3 and transverse 4 manure channels, closed on top of the grilles 5, bearing support 6, which is attached to the end of the flexible cylindrical screw opposite to the drive, the drive shaft 2 is passed through a splash shield 7.

The device operates as follows. Liquid and semi-liquid manure through the lattice 5 enters the longitudinal manure channel 3, where it is captured by the working body 1 and moves to the transverse manure channel 4, from which the working body 1 manure is removed through the transverse channel 4 from the premises.

For the normal course of the process of manure removal, first turn on the drive 2 of the working body 1, located in the transverse manure channel 4, and then the drive of the working body in the longitudinal manure channel 3. The working body 1, located in the longitudinal manure channel 3, at the beginning of the process is installed in the lower the right corner of the canal (see figure 2), and then, as the manure is unloaded, it is moved along the bottom to the left corner of the canal. The working body 1, located in the transverse channel 4, is set so that the flow of manure supplied by the working body 1 from the longitudinal manure channel 3 falls along the axis of symmetry of the channel, and then move along the bottom of the channel.

Suspended execution of the working body eliminates its contact with the bottom and walls of the channel, which reduces the friction force and, as a result, the wear of the working body. The fastening of the end of the flexible cylindrical screw opposite to the drive provides the necessary tension of the working body, which eliminates the fluctuation of the working body and leads to a reduction in energy consumption for the drive. The execution of the working body with the ability to move along the bottom of the canal allows for the removal of manure from rooms with manure canals of various shapes and widths.
