Rotary-tiller connecting member for hanging knife shaft to hanging knife holder

Abstract

The invention discloses a rotary-tiller connecting member for hanging a knife shaft to a hanging knife holder. The connecting member is characterized by comprising a vertical block, of which the middle part in the vertical direction is provided with a bent part, the upper end of the vertical block is vertically and fixedly connected with a horizontal connecting plate which is used for being connected with the lower surface of the hanging knife holder, a through groove, of which the opening is downward and the cross section is U-shaped, is formed in the lower end of the vertical block, and the length direction of the through groove is consistent with the width direction of the vertical block; and connecting holes which can be penetrated by inserted pins are further formed in a groove wall of the through groove in a vertical penetrating manner. The connecting member further comprises a cylindrical bearing sleeve, wherein the external surface of the bearing sleeve is vertically and fixedly connected with an insert block which can be inserted into the through groove, the insert block is inserted into the through groove, is provided with penetrating holes which correspond to the connecting holes and is detachably connected with the through groove through connecting bolts, and the knife shaft penetrates through and is fixedly on the bearing sleeve in an inserting manner. The connecting member has the advantages of simple and reasonable structure, low construction cost and high assembling efficiency.

Description

technical field [0001] The invention belongs to the field of tillage machinery, and in particular relates to a connecting piece on a rotary tiller for suspending a knife shaft to a hanging knife frame. Background technique [0002] A rotary tiller is a tillage machine that is matched with a tractor to complete plowing and harrowing operations. It has been widely used because of its strong soil breaking ability and flat surface after plowing. At the same time, it can chop up the root stubble buried below the surface, which is convenient for the seeder to operate and provides a good seed bed for later sowing. [0003] At present, most of the rotary tillers in the prior art are driven soil tillage machines with rotating cutter teeth as the working parts, such as the ridge rotary tiller disclosed by the patent with the notification number CN203251582U. The ridge rotary tiller includes a frame main body , the reduction box arranged in the middle of the front of the main body of ...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned ridging rotary cultivator needs to be connected with the corresponding engine before it can be used. In this way, the structure of the ridging rotary cultivator must be equipped with a corresponding reduction box, gear box and transmission shaft, which makes its structure more complicated. And the cost is high, which will increase the burden on farmers
