Problems solved by technology

[0003] However, most of the working places of agricultural machinery are on uneven ground, which leads to obvious deviations in the process of operation. Setting the depth of tillage will produce a large difference; straw crushing equipment will also cause incomplete crushing in the operation due to uneven ground, which will lead to poor agricultural machinery operations
There are also some manufacturers in China who consider these factors and invent some machines and tools, but the results are not ideal. For example, some manufacturers add balance adjustment devices to the supporting plates of the machines during design, and some manufacturers add some auxiliary mechanisms between the machines and the tractor. It does not overcome the influence of the uneven surface on the operation of agricultural machinery

Abstract

Provided is a floating type three-point suspension device. A horizontal sensor (14) is installed on the upper portion of a gearbox and connected with a hydraulic control valve (7). A left guide groove (8) and a right guide groove (4) are both of a hollow structure, the upper end of the left guide groove and the upper end of the right guide groove are connected to the left end and the right end of a suspension beam respectively, and the lower end of the left guide groove and the lower end of the right guide groove are connected to the upper portion of a rack. A left hydraulic oil cylinder (11) and a right hydraulic oil cylinder (3) are arranged in the left guide groove and the right guide groove respectively, the fixed end of the left hydraulic oil cylinder and the fixed end of the right hydraulic oil cylinder are connected with the left end and the right end of the suspension beam respectively, and the telescopic end of the left hydraulic oil cylinder and the telescopic end of the right hydraulic oil cylinder are connected with a left movable sliding block (9) and a right movable sliding block (5) respectively. A left suspension plate (10) and a right suspension plate (6) are connected to the left movable sliding block and the right movable sliding block respectively. The floating type three-point suspension device is simple in structure, mechanical-electric-hydraulic integration is achieved, influences caused by an uneven earth surface on working of an agricultural machine can be better avoided, the working effect of the agricultural machine can be improved, and meanwhile the service life of the agricultural machine can be prolonged.

Description

technical field [0001] The invention relates to a three-point suspension device, in particular to a floating three-point suspension device, which belongs to the technical field of agricultural machinery. Background technique [0002] At present, most agricultural machinery is powered by tractors. The connection methods of implements and tractors can be divided into direct traction type and three-point suspension type. Among them, the connection method of three-point suspension is more widely used, such as in land preparation machinery. Due to the structure of the tractor, the three-point suspension farm implements are widely used. [0003] However, most of the working places of agricultural machinery are on uneven ground, which leads to obvious deviations in the process of operation. Setting the depth of tillage will produce a large difference; straw crushing equipment will also cause incomplete crushing in the operation due to uneven ground, which will lead to poor agricul...
