Description
Technical field
The utility model relates to agricultural machinery, relates in particular to the cutter sweep of agricultural crop straw, rice stubble etc.
Background technology
Existing agricultural combine does not have the cutter sweep of agricultural crop straw, rice stubble etc., and after cereal is gathered in, the stalk stubble is stayed in field arbitrarily.
If retain longer stalk stubble in harvesting process, be conducive to the threshing of the farmings such as harvesting grain, but be unfavorable for the farming in farmland and the recycling of agricultural crop straw, affect the germination rate of crops in the coming year, be unfavorable for rotary tillage and sowing; If retain shorter stalk stubble in harvesting process, can be unfavorable for again the threshing of crops, grain threshing can be mingled with more cereal after getting rid of, and causes waste.
If in harvesting process, can guarantee that the stalk stubble is effectively processed and gone back field, can guarantee again in harvesting process not affect the clean degree of threshing harvesting, be still current industry technical problem urgently to be resolved hurrily.
The utility model content
Problem to be solved in the utility model is to provide and a kind ofly stalk stubble cutting can be reached to crushing effect and be convenient to also field, and efficiency is high, does not affect the stalk stubble cutter sweep of threshing cleanliness.
The purpose of this utility model is achieved by the following technical solution:
A kind of stalk stubble cutter sweep, comprise body and the ceding of Taiwan, in the described ceding of Taiwan, is fixed with delivery chute, and described cutter sweep is between described body and the described ceding of Taiwan, and described cutter sweep comprises cutter frame, cutter group, fixed mount and feeding wheels; Described cutter frame is fixed on described fixed mount; Described cutter group comprises a plurality of tool sections and a plurality of cutter groove, and described a plurality of tool sections are placed in described a plurality of cutter groove; Described cutter groove is fixed on described cutter frame; Described a plurality of tool section is connected with bent axle by connecting rod; Described fixed mount is rotationally connected with on body; Described feeding wheels are sheathed on described central shaft and are fixed on described cutter frame; Described feeding wheels comprise a plurality of feeding units, between two adjacent described tool sections, are provided with described feeding unit.
Further, described feeding wheels comprise a plurality of feeding units and central shaft, and described a plurality of feeding units are sheathed on described central shaft, and described central shaft rotates the described a plurality of feeding units of drive and rotates; Described feeding unit at least is provided with two feeding pawls; Described feeding pawl is between described adjacent two described tool sections; Bent axle, described central shaft is connected with described bent axle, and described bent axle is connected with driving, and by described bent axle, drives described central shaft rotation and tool section swings.
Further, described tool section is formed by connecting by a plurality of blade rivet weldings.The diameter of described bent axle is not less than the width of described blade.
Further, each described feeding unit is provided with a plurality of described feeding pawls, as 3,5 etc.
Further, the feeding pawl of described feeding unit between described adjacent two described tool sections, described feeding pawl and described tool section are not at grade.The external diameter of described feeding unit surpasses the rear edge of described tool section.
Further, the diameter of described bent axle is not less than the width of described blade.
Further, adjusting rod connects described delivery chute and described fixed mount and regulates distance between the two.
The achieved beneficial effect of the utility model is: can directly cut the stalk stubble in the process of harvesting, avoid secondary work, improve operating efficiency, reduce labour cost.
