Embodiment Construction

[0019] In order to further elaborate the technical means and effects that the present invention adopts for reaching the intended invention purpose, below in conjunction with the accompanying drawings and preferred embodiments, the specific implementation, structure, features and effects of the present invention are described in detail as follows:

[0020] The idea of ​​this application is to use the characteristics of small sesame seeds and difficult threshing, and use the growth characteristics of sesame seeds and stems to separate sesame seeds, solve the prominent problems of poor threshing effect and high loss rate of sesame seeds, and improve the effect of sesame threshing.

[0021] A concave screen for sesame threshing drum unit, installed on the threshing drum, such as Figure 1 to Figure 4 As shown, it includes a support frame 1, a screen 2, an upper arc baffle 3 and a lower arc baffle 4.

[0022] The support frame 1 is used to install the concave screen on the sesame d...

Abstract

The invention discloses a concave screen for a sesame threshing cylinder device, and relates to the technical field of sesame cylinder threshing. The concave screen comprise a support frame for mounting, a mesh screen, at least one upper arc-shaped baffle and at least one lower arc-shaped baffle, wherein the mesh screen is arranged in the support frame; the at least one upper arc-shaped baffle isarranged in the support frame and above the mesh screen; the at least one lower arc baffle is arranged in the support frame and below the mesh screen. The concave screen has the beneficial effects that by high-speed rotation of a threshing cylinder, sesame and the baffles are impacted, grains are forced to be effectively separated from shells, so that threshing efficiency of the sesame is improved, key problems of poor threshing effect, high loss rate and the like of the sesame are solved, the actual sesame seed and stem separation effect of the threshing device is improved, and the concave screen has simple structure, high quality and high efficiency.

Description

technical field [0001] The invention relates to the technical field of sesame drum threshing, in particular to a concave screen used for a sesame drum threshing device. Background technique [0002] At present, during the sesame harvesting process, the sesame stalks are often manually beaten to separate the seeds from the sesame capsules, which is low in efficiency, high in cost, and time-consuming. Some of them are separated by simple mechanical devices. The disadvantage is that they are not suitable for the threshing device in the sesame combine harvester, and the threshing effect is not good, the loss rate is high, and the threshing seeds contain a lot of impurities, which makes subsequent processing difficult and increases the processing of sesame. process. Contents of the invention [0003] The purpose of the present invention is to solve the problems of poor threshing effect, large grain loss, and many impurities in the current mechanized harvesting process of sesam...
