Embodiment 1

[0038] Embodiment 1, with reference to Figure 1 to Figure 6 .

[0039] The sand rice thresher provided by the present embodiment, such as figure 1 As shown, it includes a frame 700 , a cleaning and separating assembly and a sand rice threshing mechanism, and the sand rice threshing mechanism and the cleaning and separation assembly are arranged on the frame 700 . The sand rice threshing mechanism provided by the invention, such as figure 1 Shown, comprise threshing chamber 100, threshing assembly 102 and power unit 104; A plurality of first cutters 114 are arranged at intervals on the circumferential surface, and the threshing cylinder 112 is rotatably installed in the threshing chamber 100 , and the power device 104 drives the threshing cylinder 112 to rotate.

[0040] Sand rice does not have ears similar to crops, therefore, general threshers cannot achieve the threshing of sand rice. In this application, the whole plant of sand rice is sent into the threshing chamber 100...

Embodiment 2

[0060] The present embodiment provides a method for threshing sand rice, including the following steps: rolling and chopping step: crushing and chopping the whole plant sand rice; screening step: screening out the fallen sand rice seeds; bract cleaning step: using upward The bracts and sand rice particles are separated by sucking away the bracts.

[0061] It should be noted that the sequence of the above steps does not represent the sequence of threshing. The three steps can be carried out at the same time, or can be carried out in a manner such as the crushing step, the screening step, and the bract cleaning step.

[0062] The method of crushing and chopping the whole plant of sand rice overcomes the problem that sand rice has no ears similar to rice and other crops, the seeds are wrapped in each leaf axil of the plant, and the whole plant has thorns, which cannot be harvested by conventional threshers. The bract cleaning step of sucking up the bracts is because the bracts a...

Abstract

The invention discloses an agriophyllum squarrosum threshing mechanism, a threshing machine and a threshing method, and belongs to the field of threshing devices. The agriophyllum squarrosum threshing mechanism comprises a threshing chamber, a threshing component and a power device, a material receiving screen is arranged at the bottom of the threshing chamber, the threshing component comprises a threshing roller, a plurality of first cutting knives are arranged on the circumference surface of the threshing roller at intervals, and the threshing roller is rotatably arranged in the threshing chamber. The threshing machine comprises a frame, a selection and separation component and the agriophyllum squarrosum threshing mechanism, the selection and separation component comprises a vibration box with a vibrating screen, and the vibration box is obliquely arranged. Agriophyllum squarrosum does not have tassels similar to corps such as rice, seeds are wrapped by tassels with splinters in leaf axillae on plants, overall plate has splinters, the agriophyllum squarrosum cannot be harvested by the aid of a conventional threshing machine. According to the agriophyllum squarrosum threshing mechanism, the threshing machine and the threshing method, the agriophyllum squarrosum is threshed by cutting off the overall plants, shortcomings of an existing mode are overcome, and the threshing efficiency of the agriophyllum squarrosum is greatly improved.

Description

technical field [0001] The invention relates to the field of threshing devices, in particular to a sand rice threshing mechanism, a thresher and a threshing method. Background technique [0002] Shami is a wild desert plant, not a crop, and does not have long spikes similar to crops. Sami only lives on mobile sand dunes. The plant is tall and thorny. The seeds are small and oblate. Xiaosui. The tip of the leaf is prickly. Because of the prickly body and the seeds are all over the whole plant, it cannot be harvested by conventional threshers. [0003] After being exposed to the high temperature in summer, some seed bracts will crack, and they will fall off with the strong wind and sand blowing and vibration in the desert. When sand rice is manually harvested and threshed, it can only be collected slowly with a mallet, which is time-consuming and laborious, and the harvesting efficiency is poor. It is very difficult to obtain a large number of sand rice seeds. Contents of...
