Umbrella-shaped uniform distributing machine for grains in grain tank

Abstract

The invention relates to an umbrella-shaped uniform distributing machine for grains in a grain tank, and belongs to agricultural machinery. A conical cap is mounted at the top end part of a column type frame; a plurality of hanging supporting rods are uniformly and fixedly distributed at the upper part of the upper side of the column type frame in the circumferential direction; fan-shaped uniformdistributing flow-guiding plates are hinged to the outer end parts of a plurality of the hanging supporting rods; a sliding sleeve slides on a position on the lower sides of a plurality of the hangingsupporting rods, on the column type frame in a manner that the sliding sleeve is positioned in the circumferential direction and the radial direction, and can move in an axial direction; two ends ofa supporting and regulating driving rod are respectively hinged to the sliding sleeve and the fan-shaped uniform distributing flow-guiding plates; a pin shaft is fixedly mounted on the sliding sleeve;a motor is mounted on the column type frame through a side frame; a cylinder is fixedly connected to a motor shaft; a spiral trench is formed in the outer part of the cylinder; and the pin shaft canbe inserted in the spiral trench in a sliding and matching manner. Through the adoption of the umbrella-shaped uniform distributing machine for grains in a grain tank disclosed by the invention, the utilization rate of effective volume of the grain tank is increased, the frequency of stopping a machine for unloading grains in the operation process of a combined harvester is reduced, the operationauxiliary time is reduced, and the operational efficiency of machines and tools is improved; and the umbrella-shaped uniform distributing machine for grains in a grain tank is reasonable and simple instructure, simple, easy and convenient to adjust and control, and good in uniform distributing effects.

Description

technical field [0001] The invention belongs to agricultural machinery, and mainly relates to a grain evenly distributing device installed in the grain box of a combine harvester at the lower part of the grain outlet. Background technique [0002] Due to the deficiencies and defects in structural design, the grain outlets of the grain transport auger on the current combine harvester directly spray the crop grains in the grain tank, resulting in the uneven distribution of the crop grains accumulated and stored in the grain tank. As a result, the effective volume of the grain tank cannot be fully utilized and utilized, resulting in frequent grain unloading and increased auxiliary time during the operation of the equipment, which affects and reduces the operating efficiency of the combined harvesting equipment. Contents of the invention [0003] The purpose of the present invention is to solve the problems existing in the above-mentioned prior art and combine the actual needs...
