Embodiment 1

[0013] Combine below figure 1 , figure 2 The structure of Embodiment 1 of the present invention will be described in detail. The complete device of this embodiment includes a hydraulic lifting device 1 arranged on a self-propelled agricultural machine and a gear box 7 as a gear coupling driving device. The output end of the hydraulic lifting device has a pair of left and right lifting arms 2, 3 that can swing, and the extended ends of the two lifting arms are respectively hinged with one end of the left and right lifting rods 4, 5, and the left and right lifting rods 4, The other end of 5 is respectively hinged with the two sides of one end of the pull rod 6, and the other end of the pull rod 6 passes through the left and right connecting plates 20, 21 and the left and right bushings 12, 22 which are set on the output shaft 10 of the gear coupling driving device 7 respectively. Fixed connection, the left shaft sleeve 12 is fixedly connected with the upper end of the chain d...

Embodiment 2

[0018] This embodiment is a gear direct-coupled hydraulic suspension device in a crawler self-propelled field management machine, and its basic structure is substantially the same as that of Embodiment 1, as image 3 As shown, the left and right lifting rods 4 (5) are formed by the upper section and the lower end of the threaded connection, so the length can be adjusted as required, and then locked by the lock nut.

[0019] The above embodiments have been successfully applied to the crawler self-propelled garden management machine, which can effectively adjust the tillage depth according to the actual working conditions of the working area, and maintain the stability of tillage and the high efficiency of power transmission to meet different operating requirements. In summary, its advantages are as follows:

[0020] 1) The combination of the hydraulic suspension mechanism and the gear transmission mechanism not only realizes the stability and high work efficiency of the rotary ...

Abstract

The invention relates to a gear direct connection hydraulic suspension device which belongs to the technical field of agricultural machinery. The device comprises a hydraulic lifting device which is installed on a self-propelled agricultural machine and a gear connection drive device, wherein the hydraulic lifting device is provided with a lifting arm, one end of the lifting arm is hinged with one end of a lifting rod, the other end of the lifting rod is hinged with one end of a pull rod, the other end of the pull rod is fixedly connected onto a shaft sleeve which is sleeved on an output shaft of the gear connection drive device, the shaft sleeve is fixedly connected with a chain disc shell, a drive sprocket which is positioned on the upper end of the chain disc shell is assembled on the output shaft, and a driven sprocket which is in transmission connection with the main sprocket is assembled on the lower end of the chain disc shell. The purpose of the suspension device is realized through the organic combination of the hydraulic lifting device and the gear connection drive device, and the suspension device is suitable for occasions widely, is convenient to install and operate and is particularly suitable for agricultural implements for orchard, tea garden and facility greenhouse operation.

Description

technical field [0001] The invention relates to an agricultural machinery suspension device, in particular to a gear direct-coupled hydraulic suspension device suitable for self-propelled small-scale agricultural machinery in orchards, tea gardens and facility greenhouses, and belongs to the technical field of agricultural machinery. Background technique [0002] As a power machine, the four-wheel tractor finally transmits the power through the connection between the tractor and the farm implements. The hydraulic suspension device uses hydraulic pressure as power to control the lifting and lowering of farm tools. As far as the applicant knows, the existing suspension methods include two-point suspension and three-point suspension. The two-point suspension mechanism is connected with the tractor body by two hinge points, which can easily correct the driving direction when the agricultural machinery is working, and is often used on high-power tractors. The three-point suspen...
