Improved seed extrusion prevention mechanism for agricultural machinery tillage machine

Abstract

The invention provides an improved seed extrusion prevention mechanism for agricultural machinery tillage machine. The improved seed extrusion prevention mechanism comprises a seed box, a support shaft rod and chain wheels; the seed box is arranged in an inverted trapezoid as a whole, nine leakage ports are formed through the bottom plate of the seed box, a main rotating shaft rotates across the position of the bottom of the inner space of the seed box, and nine shift wheels are fixed equidistantly on the main rotate shaft in a sleeving manner and are just located in the corresponding leakageports in a rolling manner; two chain wheels are fixed on head and tail protruding sections of the main rotate shaft in a sleeving manner and are respectively connected with a connecting rod rotatably;nine slip-in frames are equidistantly arrayed on the support shaft rod in a downward support manner and are inserted in the seed box to sleeve the corresponding shift wheels, two positioning frames can be pulled down quickly by spring push installation to be removed so that the support shaft rod and the slide-in frames can be removed flexibly, and cleaning of the interior of the seed box is facilitated.

Description

technical field [0001] The invention belongs to the technical field of tillage machinery, and more specifically relates to an improved anti-crowding mechanism for agricultural machinery tillage machines. Background technique [0002] Replacing manual seeding with a seeder has become the mainstream. The use of a seeder for seeding is efficient, labor-saving and time-saving. However, most of the seed box structures of the seeder on the market currently adopt a straight-through type. There is a seed opening at the bottom of the seed box, and the seeds are directly Slide directly from the upper edge of the seed box to the seed opening. This structure is prone to clogging the seed opening during the actual production process. This requires optimization and improvement to design a cultivator with an anti-crowding mechanism. For example, the patent number is CN201620422506 The patent of .6 discloses an anti-clogging seeding box, comprising: an upper box body, a lower box body, a ro...

Problems solved by technology

[0004] In order to solve the above-mentioned technical problems, the present invention provides an improved anti-crowding mechanism for agricultural machinery tillage machines, to solve the problem that most of the tillage machines only do anti-crowding and anti-clogging optimization design for the feeding tube, ignoring the design of the feeding port. The problem of blockage, resulting in poor penetration effect on the feeding port, and the problem that the leaking port is easy to block and squeeze seeds
