Crop straw impurity removing machine

Abstract

The invention provides a crop straw impurity removing machine. The crop straw impurity removing machine is composed of a rack, a guide rail, a vibrating screen, a connecting pin I, a guide rod, an eccentric wheel, a motor I, a feeding opening, a swing rod, a motor II, a conveying device, a motor III, a connecting pin II, a connecting pin III, a pulley, a grass stirring roller I, a bearing pedestalI, a bearing pedestal II, a grass stirring roller II, a belt wheel I, a belt wheel II, a belt I, a belt II and a belt wheel III. During work, crop straw entering from the feeding opening is continuously scattered and stirred away through the grass stirring roller I, then falls into the vibrating screen, is scattered again through the grass stirring roller II and is evenly laid on a screen net; under the action of the vibrating screen, small impurities mixed in the crop straw fall to the ground through the screen net, and the remaining crop straw continues to fall along the screen net; and when the remaining crop straw falls to the position below an adjusting material opening of the conveying device, a draught fan sucks clean crop straw with the small specific gravity in a negative pressure manner and throws the clean crop straw out through a material throwing opening, and impurities with the large specific gravity left on the screen net continue to fall to the ground under the actionof the vibrating screen.

Description

technical field [0001] The invention belongs to the field of animal husbandry machinery, and in particular relates to a crop straw remover used in animal husbandry farms. Background technique [0002] During the picking and recycling process of crop straw, some sundries such as soil, gravel, and iron will be mixed into it and collected and packaged. During the subsequent crushing process, these sundries mixed in the crop straw will damage the hammers, blades, etc. Therefore, it is necessary to remove impurities from the collected crop stalks. The crop straw removal machine used in the market at this stage is mainly based on vibrating sieve soil. The dust and small debris mixed in the straw are screened out through the vibrating sieve, and the materials on the sieve surface are collected, and some large Large pieces of sand and iron are still mixed in the crop straw, and the removal of impurities is not thorough. When entering the pulverizer for processing, the high-speed ro...

AI Technical Summary

Problems solved by technology

The crop straw removal machine used in the market at this stage is mainly based on vibrating sieve soil. The dust and small debris mixed in the straw are screened out through the vibrating sieve, and the materials on the sieve surface are collected, and some large Large pieces of sand and iron are still mixed in the crop straw, and the removal of impurities is not thorough. When entering the pulverizer for processing, the high-speed rotating hammer or blade encounters these debris, which is easily worn or even broken. The edges and corners are off, unusable, and need to be replaced in time, which not only reduces the work efficiency, but also increases the production cost, and the crop straw containing sand and gravel, especially the iron wire and iron block, etc., will be harmful to the livestock if they are used as feed for livestock. have a certain impact on the health of

Therefore, the existing crop stalk removal machines at this stage cannot completely remove impurities and cannot adapt to the rapid development of the animal husbandry industry.
