SU107808A1 - Corn Threshing Crushing Machine - Google Patents

Description

It is known the use of the cornAjo .TOTHJioiC and 1e .; threshing devices for threshing crumbs, as well as crushers 1 of universal mills for crushing grain, in particular, fraction, 1 corn. It is also known the use of pneumatic tractors in various types of agricultural machines;

Predictable .1 latil of o-fractional .1 on a machine does not differ much from the CBoeii mines, but also from the grain crushing technology itself. It applies the principle of cutting grain in place of conventional ways of grinding and breaking due to the impact of working bodies.

MD-2 is intended for threshing of corn cobs with simultaneous crushed grain for livestock and poultry feed, or only for threshing of corn cobs with simultaneous cleaning of grain from impurities.

FIG. 1 shows the main view of the machine and the cross-section; in fig. 2-main view of the impact crusher n cross section.

Receiving bunker / differs from bins of this type in that

iiaK.ioiinaH has a reflective board and a hinged flap installed in it, obstacles are thrown out through the bunker of 1,1x cobs when the drum is raised.

The threshing node 2 was adopted with the performance of N1 N1) 1 mn amended. The grain collector 3 is an inclined peHicro, through which a dip, ivan)} with grain, Bbi6pacbHjaeMi, ic ns i () lot, iс () l on the drum.

FIG. 2 shows the main components and parts of the rotor shot. Hk. In the molded case with .nc krinkoi 4 all details are enclosed.pl1) bnlki. The hull is a necyHicii construct.

The stator consists of 29 st.1. 1) 1x knives, located in the form of a lindra and fixed 1; 1x the housing and flange of the housing 6. The flange of the housing is pressed against the rail. The ridge passages between the burrows serve to exit the grits.

The rotor consists of eighth knives 7, bolted between the front disc 8 and the rear disc 9. The rear disc is dropped onto the shaft 10 by means of a sleeve and the nut is clamped. AT

The front disc has a window for the passage of grain inside the rotor.

Shaft bearings are located in the cover and housing. In addition, there is a neck in the lid for feeding grain to the inside of the crusher.

On the shaft, on one side, there is a drive pulley coupling, and on the other side, a fan rotor.

The geometry of the knives allows for blunting of the cutting edges noEso sharpen the knives by 180 ° around the axis, with the result that the knives again work with sharp edges (double use of the knives).

The electric motor 11 (Fig. 1) is adopted by the brand AO52-4.

The fan on the MD-2 is mounted dust, centrifugal with two suction pipes, which are equipped with four gates. The bottom pipe is connected to the crusher, and the top ends with a suction neck above the pipe leading from the threshing unit to the crusher.

The frame bears on itself all the nodes of the MD-2 and has pristayyukz part, which is installed lekktrbddigatel. The pristoya is connected to the main kafiKacoM bolts. Damage to electric power loss or power failure Grista6 on the part, together with the power module, can be disconnected and MautHiia mbzhet 6in1 gyrDedena in the movement of a belt drive over the Pulley.

The crusher with the threshing unit is associated with a V-belt transmission.

Corn cobs are loaded into the hopper / (Fig. 1) and get into the threshing unit 2, where they, rotating with the help of a drum, rub against each other, against the body and the grill and are threshed. Grain provalibaets through the mesh and into the collecting kovsch and obmolochennye cobs ejected through the throat at zernoulovitel 3. At the threshed ears of emitted and individual grains of about 0.5-1%, which provalivayuts zernoulovitel through the sieve 3 and obmolochennye cob skatyvayuts inclined plane cuts in a special container or just to the ground.

Subject invention

Corn threshing and crushing machine, consisting of a threshing device with a pinch drum, a filled hopper, a fan for cleaning the grain, and a transyortirovaniyu product, but with the fact that it uses a JDofHHH crusher, arranged in the form of a cylinder | It is made of steel knives, and the rotor of the drum rotates in it, the working part of which is assembled from knives, ct nytyx bolts.
