Agriophyllum squarrosum threshing and cleaning machine

Abstract

The invention discloses an agriophyllum squarrosum threshing and cleaning machine which comprises a feeding hopper, a threshing bin, a screening device and a power device, wherein a material stirring tooth set is rotationally connected into the feeding hopper, and the material stirring tooth set achieves feeding through forward-rotation material stirring and reverse-rotation material stirring; the inner side wall of the threshing bin is a bearing circumferential face, a plurality of threshing throwing piece sets are rotationally connected into the threshing bin, the inner diameter of the bearing circumferential face is larger than the rotation range of the threshing throwing piece sets, and a coarse screen is embedded in the bottom wall of the threshing bin; the screening device comprises a screen box, at least two stages of screen assemblies are arranged in the screen box, a screen group fixing buckle is movably connected between the screen assemblies, the screen group fixing buckle is movably connected with a crankshaft power structure, a discharging port is formed in the end, away from the screen group fixing buckle, of each screen assembly, and the discharging port end is lower than the screen group fixing buckle; and the power device is in transmission connection with the threshing throwing piece sets, the crankshaft power structure and the material stirring tooth set. The agriophyllum squarrosum threshing and cleaning device replaces manual threshing and cleaning of agriophyllum squarrosum, and the working efficiency is greatly improved.

Description

technical field [0001] The invention relates to the field of threshing devices and cleaning devices, in particular to a sand rice threshing and cleaning machine. Background technique [0002] Sand rice is an annual wild desert plant, which grows in mobile and semi-mobile sand dunes. The fruit of sand rice is oval or oval. Essential amino acids are processed into foods such as jelly, steamed buns, and noodles. The food is warm and mellow, helps digestion, strengthens the spleen and stomach, and is used as both vegetables and grains. It is a functional food. [0003] When sand rice is harvested and threshed, the traditional method is to shovel the plant from the ground stem with a shovel, place it on a cloth sheet, beat it with a wooden stick or roll it with a stone, and pick out large impurities such as branches and stems. Then use a sieve and a dustpan to select the sand rice seeds. This method is time-consuming and labor-intensive, and the harvesting efficiency is poor. T...

[0003] When sand rice is harvested and threshed, the traditional method is to shovel the plant from the ground stem with a shovel, place it on a cloth sheet, beat it with a wooden stick or roll it with a stone, and pick out large impurities such as branches and stems. Then use a sieve and a dustpan to select the sand rice seeds. This method is time-consuming and labor-intensive, and the harvesting efficiency is poor. The working efficiency of the threshing and cleaning method is poor, and it cannot meet the needs of threshing and cleaning when a large amount of sand rice is harvested, and the existing crop threshing and cleaning devices are not suitable for threshing and cleaning of sand rice
