Agricultural accurate adjusting mechanism for fertilizer spreading

Abstract

The invention relates to an agricultural accurate adjusting mechanism for fertilizer spreading, which comprises a rack upper cross beam (1) and is characterized in that a U-shaped connecting base (3)is installed on the outer side of a connecting plate (2). A swing arm (8) is installed on the U-shaped connecting base (3) through a swing shaft (9), a lower connecting shaft (10) and an upper connecting shaft (11) are arranged on the swing arm (8) separately, a one-way swing arm assembly (17) is arranged on the inner side of a first installation base (4), and an output shaft (17) is mounted in anaxis mounting hole of a first bearing base (6) and the one-way swing arm assembly (18). Mutually-limited one-way rotation is achieved through a first one-way bearing and a second one-way bearing, thetwo one-way bearings swing under the action of the one-way swing arm assembly, and the fertilizing amount and the seeding amount can be adjusted by adjusting the rotating angle of the output shaft according to needs. Meanwhile, a crank rocker mechanism and a lock catch adjusting device are further adopted, the length of a crank is adjusted by installing the crank rocker mechanism and the lock catch adjusting device into different hole sites, and then the fertilization amount is accurately adjusted.

Description

technical field [0001] The invention relates to a fertilizer spreading adjustment mechanism, in particular to an agricultural fertilizer spreading precision adjustment mechanism, which belongs to the technical field of agricultural machinery. Background technique [0002] At present, in the seeding and fertilizer spreading machines in agricultural machinery, it is necessary to adjust and control the amount of fertilizer spreading, and apply the corresponding amount of fertilizer according to the amount of fertilizer required by different plants. The existing seeding and fertilizer spreading machine adjustment device has a simple structure and cannot accurately adjust the amount of fertilizer spreading. It is easy to cause too much or too little fertilizer spreading, and it will also cause waste of fertilizer. There has been a lack of an effective mechanical device to change this. One behind the status quo. Contents of the invention [0003] The purpose of the present inve...

Problems solved by technology

[0003] The purpose of the present invention is to solve the defects and insufficiencies of the existing adjusting device of the seeding and fertilizer spreading machine, which are simple in structure, unable to accurately adjust the amount of seeding and spreading fertilizer, poor adjustability, and unable to meet the needs of actual agricultural production, and now provide a structure It is compact and ingeniously solves the technical problem of accurately adjusting the amount of seeding and fertilizer spreading. It is a precise adjustment mechanism for agricultural fertilizer spreading with good adjustability and high stability.
