Straw pullout machine

Abstract

The invention provides a straw pullout machine which comprises a harvest box body, a receiving plate, a mud outlet, a conveying belt, fixing roll fixing rods, fixing rolls, a clearing screen, a clearing screen fixing rod, a guide plate, a non-return plate, a flow guide plate, soil crushing bulges, grass separation claws, a driving rod, driving teeth, support teeth, soil breaking claws and a baffle, wherein the receiving plate is fixedly arranged on the bottom surface in the harvest box body; the mud outlet is formed in the bottom surface of the harvest box body; the fixing roll fixing rods arefixedly arranged in the harvest box body; the fixing rolls are fixedly arranged at the peripheries of the fixing roll fixing rods; the peripheries of the fixing rolls are wound with the conveying belt; due to obstruction of the guide plate, large soil blocks crushed from straw stubble are kept at the low-half part of the clearing screen; the soil blocks are discharged from holes of the clearing screen through constant movement of the clearing screen; the grass separation claws continuously rotate straws along the clearing screen and hook the straws above the clearing screen; at the same time,the straws fall to the flow guide plate due to deadweight and move to an inclination of the flow guide plate; the amount of soil brought by the straws pulled out by the straw pullout machine is reduced.

Description

technical field [0001] The invention belongs to the technical field of straw pulling structure, and more specifically relates to a straw pulling machine. Background technique [0002] Existing grain crops with straw such as rice are mostly harvested by machines, but the machine will not completely pull out the straw, and will leave a stubble of more than ten centimeters long, so that the stubble and root system of the straw will remain in the lower part of the ground , but most of the rod pulling machines are single-plant straw stubble positioning and pulling out, and then the soil on the root system of the straw stubble is manually shaken off and then recycled. Based on the above description, the existing straw pulling machine can only pull out the straw stubble. The soil at the bottom of the straw stubble cannot be cleaned, so that the post-treatment straw soil work consumes more time. Contents of the invention [0003] In order to solve the above technical problems, th...
