A two-way rollover grain unloading mechanism for a harvester

Abstract

A bi-directional side-turning grain unloading mechanism for a harvester comprises left side-turning grain unloading devices, right side-turning grain unloading devices, side-turning rod limiting devices, a rack, a grain tank and oil cylinders, wherein the two left side-turning grain unloading devices are arranged on the left side of the grain tank, symmetrically arranged on front and back sides of the grain tank respectively and mounted on the rack; the two right side-turning grain unloading devices are arranged on the right side of the grain tank, symmetrically arranged on front and back sides of the grain tank respectively and mounted on the rack; the grain tank are arranged in positioning grooves of positioning shafts on two sides of the rack through rotating shafts on two sides; one end of each oil cylinder is mounted on the rack through a hinge pin, and the other end is assembled and connected with the grain tank; the four side-turning rod limiting devices are arranged on the inner sides of the left side-turning grain unloading devices and the right side-turning grain unloading devices respectively and mounted on the grain tank. With adoption of the structure, side turning in either direction for grain unloading can be realized only through operation of the corresponding hydraulic handle, the operation is simple, and the harvest efficiency is improved.

Description

Technical field [0001] The invention relates to a two-way side turning grain unloading mechanism for a harvester, belonging to the field of machinery. Background technique [0002] At present, the side tipping and unloading mechanisms of harvesters developed on the domestic market are mostly one-way side tipping and unloading mechanisms, and the direction of unloading grain is restricted, especially when unloading grain onto a transport vehicle, the unloading port must be transferred to the transport vehicle compartment Side, before unloading grain to the carriage. Due to the long time used for shunting, more time is wasted, which affects harvest efficiency and increases fuel consumption. In addition, there are side-turning and unloading mechanisms on the market. When you want to change the direction of side-turning and unloading the grain, you must manually change the position of the oil cylinder or the rotary pin of the grain box before you can turn the grain in the other dire...

AI Technical Summary

Problems solved by technology

[0002] At present, most of the rollover grain unloading mechanisms of harvesters developed in the domestic market are one-way rollover grain unloading mechanisms, and the unloading direction is limited. Especially when unloading grain on the transport vehicle, the grain unloading port must be adjusted to the transport vehicle compartment side, before unloading grain into the compartment

Because the shunting takes a long time, more time is wasted, which affects harvesting efficiency and increases fuel consumption

In addition, there are rollover grain unloading mechanisms on the market. When you want to switch to rollover grain unloading, you must manually change the position of the oil cylinder or grain tank rotary pin to realize rollover unloading in the other direction. The operation is very difficult. Complicated, takes a long time, and is too inefficient
