Problems solved by technology

[0004] The present invention mainly solves the problem that a large amount of broken grass in the grid screen in the prior art is difficult to separate the broken grass from the grain through the grid, and the subsequent screening workload is large, and its strength is relatively low; Sieve and divide so that a large amount of grains are separated as broken grass without punching holes, resulting in a lot of waste and other technical problems. To provide a thresher with a simple structure, easy to use, and good separation of broken grass and grains Concave screen

Embodiment 1

[0020] Such as figure 1 , figure 2 As shown, the present invention is a novel half-feed threshing concave plate screen, which is composed of a sieve plate and a partition for separating the sieve plates, and the sieve plate is formed by connecting a punching screen 2 and a grid screen 1, The highest point of the sieve plate is set at 1 / 2 height of the corresponding threshing drum. The lower side of the sieve plate is provided with several reinforcing ribs 3, which are respectively arranged on the lower side of the partition plate and the front and rear sides of the sieve plate, and coincide with the sieve plate. The partitions are divided into punching screen partitions 22 and grid screen partitions 11, which are respectively arranged on the upper side of the punching screen 2 and the grid screen 1, and the punching screen and the grid screen are correspondingly divided into 3 There are three threshing areas, and the punching screen is composed of three sieves, each threshi...

Abstract

The invention relates to a novel semi-feeding threshing concave plate screen comprising a screen plate and a baffle plate for separating the screen plate. The novel semi-feeding threshing concave plate screen is characterized in that the screen plate is formed by connecting a punching screen with a grid screen, wherein the punching screen is arranged on one side of a feeding inlet; the total length of the screen plate is 1 / 2-3 / 5 of the circumference of a corresponding threshing roller; and the area ratio of the punching screen and the grid screen is 2 / 3-3 / 2. The invention provides a concave plate screen of a threshing machine simple in structure, convenient in use and capable of separating the crashed grass and the grains.

Description

technical field [0001] The invention relates to a threshing machine, in particular to a concave screen for the threshing machine. Background technique [0002] Semi-feed threshers are generally equipped with a concave screen, which plays an auxiliary role in threshing on the one hand, and also plays a role in screening on the other hand. At present, one of grid screen, punching screen or woven screen is generally used in the thresher. The screen hole of the grid screen is rectangular or square, the hole of the woven screen is square, and the punching screen is round or rectangular. Or square, one side of rectangular or square hole is parallel to the axis of threshing drum. Although the structure of several forms is simple, the screening efficiency is low, and it is not suitable for the use of a thresher with a large feeding amount. For example, the Chinese patent with the publication number CN201278691 discloses a concave screen for a miniature combine harvester, including...
