Secondary separation device for hybrid material of corn kernels

Abstract

The invention provides a secondary separation device for hybrid material of corn kernels, relates to the secondary separation devices, and solves the problems that a drum shaft and a main frame are longer in the existing secondary separation device for the hybrid material of the corn kernels, processing is difficult, and a drum part is easy to be blocked when threshing corns with the skin. A separating barrel is disposed in a separating box shell through a plurality of positioning tugs. The left end of a spindle is disposed on a support component at the left end of a separating frame, while the right end thereof sequentially penetrates out of a feeding box shell, the separating barrel of the separating box shell and a corn discharging box shell from left to right to be mounted on a support component at the right end of the separating frame. An outer spiral blade and an inner spiral blade are sleeved on the spindle in a staggered manner. A corn discharging impeller is sleeved on the spindle. A separating barrel chain wheel is sleeved on the separating barrel. A middle shaft assembly is mounted on the separating frame. A plurality of rubber blades are evenly distributed on the outer side wall of the separating barrel. The secondary separation device for the hybrid material of the corn kernels is applicable to agricultural production.

Description

technical field [0001] The invention relates to a secondary separation device, in particular to a secondary separation device for corn kernel mixed material. Background technique [0002] The secondary separation of the corncob, corncob and a small amount of corn kernels discharged from the corn detaching machine can reduce the loss of corn kernels and promote the increase of production and income. The existing secondary separation device for corn kernel mixture adopts a cylindrical sieve structure, but the drum part is placed at the rear end of the main machine drum. When peeling corn, the drum part is easy to block. Contents of the invention [0003] The invention aims to solve the problem that the drum shaft and the main frame of the existing secondary separation device for corn kernel mixed materials are relatively long, the processing is difficult, and the drum part is easily blocked when threshing corn with husks, and further proposes a corn kernel mixture Material...

Problems solved by technology

[0003] The invention aims to solve the problem that the drum shaft and the main frame of the existing secondary separation device for corn kernel mixed materials are relatively long, the processing is difficult, and the drum part is easily blocked when threshing corn with husks, and further proposes a corn kernel mixture Material secondary separation device

[0005] The beneficial effects of the present invention are: the present invention effectively solves the problem that the drum part is easily blocked when the existing thresher is separated from the husk corn. The present invention is an external separator, which effectively reduces the length of the main shaft. On the other hand, The inner helical blade of the separation cylinder and the outer helical blade on the main shaft effectively solve the clogging problem, and the rubber blade on the outer wall of the separation cylinder solves the problem that the separated corn kernels and small impurities have poor fluidity and are not easy to return to the main machine for cleaning and screening; The present invention can carry out secondary separation of the mixed material of corn cobs, corn cobs and a small amount of corn kernels discharged from the corn thresher, so as to reduce the loss rate and promote the increase of production and income; the separation loss rate of the present invention is less than 0.05%, and the volume of the present invention Small, simple structure, safe and reliable work
