RU2199203C2 - Slitter-type beater with transportation plate - Google Patents

Abstract

FIELD: agricultural engineering. SUBSTANCE: beater has base and blades attached to base. Each blade has curvilinear surface oriented forward with its convex part and equipped with restrictor positioned peripherally of curvilinear surface. Projection with threshing edge is positioned behind restrictor. Slit is defined between threshing edge and restrictor. Transporting plate located behind slit is inclined backward relative to roll radius. Transporting plate facilitates removal of threshed grains beyond threshing roll. Beater of such construction may be used in panicle crop seed harvesting machines. EFFECT: increased efficiency and simplified construction. 1 dwg

Description

 The invention relates to agricultural machinery and can be used in agricultural machines for harvesting panicle crop seeds by tow on the vine.

 Known combing working body of a threshing-separating device containing a rotating rotor mounted on it with blades with curved working surfaces made with combing grooves [1].

 The closest in technical essence to the claimed one is a combing working element "slotted beater" containing a base and blades mounted on it, each of which has a curved working surface with a limiter and a protrusion equipped with a threshing edge, while the convex part of the working surface is directed towards the direction rotation of the beater, and the limiter is located at the peripheral end of the working surface. Between the limiter and the edge of the protrusion there is a gap [2]. The invention [2] is accepted by us as a prototype.

 The disadvantage of this device is that the threshed grains are not removed from the threshing zone, but remain behind the blade. The next blade with its working surface ejects these grains from the threshing zone. Grains, located in the threshing zone, impede free access to grains that have not yet been threshed. This to some extent limits the performance of the threshing and separating device.

 The problem to which the claimed invention is directed is to increase productivity.

 The technical result is an improvement in the process of removing threshed grains from the working area due to the release of the threshing gap by the transporting plate from grains threshed by the blade.

 The specified technical result in the implementation of the invention is achieved by the fact that in the well-known working body "slotted beater" behind the slit is installed a transport plate inclined backward relative to the radius of the roller.

 The drawing shows a diagram of the proposed device.

 The slit beater contains a base 1, on which the blades are fixed 2. The number of blades can be from 1 to 6. Each blade 2 has a curved shape working surface 3 with a convexity forward, which ends in the direction from the base 1 to the periphery 4. The limiter 4 is located behind the limiter 4 a protrusion 5, the front of which is provided with a threshing edge 6. A gap 7 is formed between the edge 6 and the limiter 4, a transport plate 8 is installed behind the gap 7 on the back of the blade 8. To make the structure rigid, each the mouth is provided with a bracket 9.

 The operation of the device is as follows.

 Plants are fed into the gap between two beaters (the second beater is not shown in the drawing). Beaters alternately stroke 2 panicles of plants from the base to the top with their blades, passing them from one beater to another. The grains attached to the panicle through the peduncle overlap around the stripping edge 6 and fall into the slot 7. The stripping edge 6 bends and breaks the stem over the length specified by the limiter 4, and the kernel passes through the slot 7 behind the blade, at a speed approximately equal to the circumferential speed of the threshing . With further movement, the threshed grain falls onto the transporting plate 8 and, due to the centrifugal force and the resulting force from hitting the plate, is thrown outside the threshing roller, in contrast to the prototype, in which the grains remain within the roller and are ejected by the next blade along the way.
