Problems solved by technology

Both two-point suspension and three-point suspension four-wheel tractors have power output through the power output shaft. They are large in size and work in places with limited space. It is inconvenient to turn around and not suitable for operation in orchards, tea gardens and facility greenhouses.
[0003] Retrieval of relevant literature so far has not found a hydraulic suspension device using gear direct coupling

Embodiment 1

[0009] The whole set of devices in this embodiment includes a hydraulic lifting device arranged on a self-propelled agricultural machine and a gear box as a gear coupling driving device. The output end of the hydraulic lifting device has a pair of swingable left and right lifting arms. The extended ends of the two lifting arms are respectively hinged with one end of the left and right lifting rods. The two sides are hinged, and the other end of the pull rod is fixedly connected with the left and right bushings set on the output shaft of the gear coupling drive device through the left and right connecting plates respectively, and the left bushing is fixedly connected with the upper end of the chain disc shell. The driving sprocket at the upper end of the chain disc housing, the lower end of the chain disc housing supports the driven shaft with the rotary tiller, and the driven sprocket connected with the driving sprocket through a chain. The driven sprocket is fixedly connected...

Embodiment 2

[0014] This embodiment is a gear direct-coupled hydraulic suspension device in a crawler self-propelled pastoral management machine. Its basic structure is substantially the same as that of Embodiment 1, wherein the left and right lifting rods are formed by threaded upper sections and lower ends, so The length can be adjusted as required, and then locked by a lock nut.

[0015] 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:

[0016] 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 tillage operation, but also can effectively adj...

Abstract

The invention relates to a direct-connected gear hydraulic hanging device, which comprises a hydraulic hoisting device and a gear connection driving device which are arranged on a self-walking agricultural machine. The direct-connected gear hydraulic hanging device is characterized in that the hydraulic hoisting device is provided with a hoisting arm, the extending end of the hoisting arm is hinged with one end of a hoisting rod, the other end of the hoisting rod is hinged with one end of a pull rod, the other end of the pull rod is fixedly connected with a shaft sleeve arranged on an output shaft of the gear connection driving device in a sheathing manner, the shaft sleeve is fixedly connected with a chain disc shell, a driving chain wheel positioned at the upper end of the chain disc shell is arranged on the output shaft, and a driven chain wheel which is in transmission connection with the driving chain wheel is arranged at the lower end of the chain disc shell through a chain. The invention relates to an agricultural machine hanging device, and particularly relates to a direct-connected gear hydraulic hanging device suitable for use when a self-walking small-size agricultural machine is running in a fruit orchard, a tea garden and facility greenhouse.

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...
