Embodiment 1

[0028] Such as figure 1 As shown, a harvester cleaning device includes an upper sieve 1 for filtering grain particles, a tail sieve 2 fixedly connected with the upper sieve, an extended high-toothed sieve 3 for further filtering grain grains, and a fence 4 for intercepting, Side fence 41 and steel plate 5.

[0029] Upper sieve 1 adopts fish scale sieve.

[0030] One end of the tail screen 2 is fixedly connected with the upper screen 1, and the other end of the tail screen 2 touches the steel plate 5 when shaking.

[0031] The upper end of the steel plate 5 is connected with an extended high-toothed screen 3 .

[0032] The lengthened high-toothed sieve is set as a rectangle, the length of the extended high-toothed sieve is the same as that of the tail sieve, and the width of the extended high-toothed sieve is 5-7cm.

[0033] The extended high-tooth sieve 3 is provided with high teeth, and the bases of the high teeth are connected; the tooth height of the high teeth is 0.5-0....

Abstract

A harvester cleaning device comprises an upper sieve for filtering grain particles, a tail sieve fixedly connected with the upper sieve, and a steel plate contacted with the tail sieve when swinging; the steel plate is also connected with a lengthened high-tooth sieve. The upper sieve is a louver sieve; the lengthened high-tooth sieve is rectangle, the length of the lengthened high-tooth sieve is the same with that of the tail sieve, and the width of the lengthened high-tooth sieve is 5-7 cm. the rear end of the lengthened high-tooth sieve is provided with guardrails, both lateral sides are provided with side guardrails. The lengthened high-tooth sieve is provided with high teeth, and the base parts of the high teeth are connected together. The lengthened high-tooth sieve is welded with the steel plate; and the lengthened high-tooth sieve is fixed on the steel plate through bolts. The tail sieve is in the horizontal position, and the lengthened high-tooth sieve is arranged at the position with inclination angle of 15-20 degrees. The invention reduces grain loss rate, improves harvesting speed and grain harvesting efficiency, has simple principle, convenient modification and low cost.

Description

technical field [0001] The invention relates to a harvester cleaning device, belonging to the technical field of harvesters. Background technique [0002] Machines such as threshers and mechanical harvesters greatly increased agricultural productivity in the 19th century. This made it possible to harvest more grain with fewer workers than before. But an invention in the late 1800s, long before the combine harvester, took this efficiency even further. Combine harvesters combine harvesting and thresher in one unit, enabling farmers to harvest and thresh in a single operation. [0003] Grain combine harvester, referred to as combine harvester, is a combined machine for harvesting crops. It was called Combine in the early 1950s. Harvesting machinery that directly obtains grain from the field. [0004] At present, combine harvesters are divided according to the grain feeding method, which can be divided into two types: full-feeding type and half-feeding type. The semi-feed h...
