Description

The device relates to the feed processing industry, in particular to agriculture, and can be used for grinding pea mowing on combines or in feed shops.

The purpose of the invention is to improve the reliability and grinding quality.

The invention is illustrated in the drawings.

Figure 1 shows a diagram of the design of the installation in cross section; figure 2 is a section aa in figure 1.

The pea milling plant contains the following main units: conveyor 1, pressure rollers 2, loading device 3, grinding drums 4,5, housing 6 with side support walls, rotational drives for drums 7.8, frame 9, for installing housing 6, drives 7, 8 and adjusting device 10, cam knives 11, a set of circular saws 12, washers 13, tightening nuts 14, V-belt drive 15, coupling drum 5 with drive 7, clutch 16, coupling drum 5 with drive 7, unloading device 17, discharge 18, fender (accompanying) w Aybu 19, between the disks of the cam knives 11, the pressure spring 20, pressing the upper rollers 2.

Installation for grinding pea floor works as follows.

Gorokhov sex enters the threshing machine for green peas (not shown), and after the selection of green peas coming out of the threshing pea thresher in the form of a moist and loosened mass (tow) through the conveyor 1 is fed to the grinding device, where after passing through the squeezing rollers 2 m giving the excess moisture - juice flowing into the storage tank through the drain 18, the compacted and dehydrated mass of the floor comes into the loading device 3 and falls on two parallel horizontally installed and rotating in different directions of the drum 4, 5 with chayuyu

cutting and cutting surfaces installed under the loading device 3 in the housing 6 with side support walls and drives 7, 8, mounted on the frame 9.

The grinding surface of the drum 4 is formed by a set of cam knives 11 assembled into the disks, the cutting surface of the drum 5 is formed by a set of circular saws 12. Washers 13 are mounted between the knives and circular saws. Knives and circular saws with washers are put on the drum shafts that have longitudinal splined grooves and are tightened laterally by nuts 14.

The distance between the drums 4 and 5 can be adjusted by the tension device 10, which will be developed in the manufacture of the grinder installed on the drum with a cutting surface. The housing 6 is connected by its upper part to the loading device 3, and the lower part to the unloading device 17.

The operation of the pea milling plant.

The floor from under the thresher (type NBC) in the form of a moist and loose mass through the conveyor 1 enters the squeeze rollers 2 of the grinding device and passes through the squeeze rollers 2, where excess moisture is collected, which is drained into the tank, and the floor is fed into the loading device 3 and from it enters the housing 6 with two parallel and horizontally mounted drums 4, 5 with separate drives 7.8, providing their rotation in opposite directions in the direction from the side walls of the housing b of the intersection line (line B) grinding she and the cutting surfaces of the drums 4, 5 located in the plane of the housing b, where the floor is pressed against the cutting surface by the action of the cam knives 11, is cut and crushed at the same time, in contact with which it moves from the walls of the housing and the loading device to the middle where it collides above line (line B) of intersection of surfaces. The crushed mass is pushed down at the time of cutting and grinding

between the gaps of the knives and circular saws and enters the unloading device. Under the unloading device, you can install a container for filling the crushed mass, which by pneumatic transport via flexible pipelines can be supplied to any point of the silo and simultaneously mixed with pre-squeezed moisture-juice.

Formula of the invention

A pea mulcher for crushing peas, including a prepress device and horizontally mounted milling drums, one of which

made in the form of a number of circular saws installed with a clearance on the shaft, and the other in the form of a series of disks with working bodies located in the gaps between the circular saws, characterized in that, for the purpose of

to increase the reliability and quality of grinding, it is equipped with a tensioning device connecting the drums, while the axes of the drums lie in one horizontal plane, and the working bodies have the form of cam knives, and the pressing device is made in the form of horizontally installed roll drums, the axes of which lie in one vertical plane, and mounted

under the lower roller of the juice collecting tray.
