Abstract

Disclosed is a hydraulic system of a full-hydraulic transplanting machine with a differential locking function, the system comprising an oil tank (15), an oil pump, a plurality of electromagnetic valves, a plurality of motors, a front wheel drive oil passage, a rear wheel drive oil passage and a transplanting oil passage, wherein the front wheel drive oil passage is connected to two front wheel drive motors (1), and a synchronization valve (3) is arranged between the two front wheel drive motors (1); the rear wheel drive oil passage is connected to two rear wheel drive motors (2), and a synchronization valve (3) is also arranged between the two rear wheel drive motors (2); the two output ends of either synchronization valve (3) are connected via an on-off valve (21); and the transplanting oil passage is connected to a transplanting motor (8). The hydraulic system has a simple structure, light weight, convenient layout, a low failure rate and low maintenance costs, and lays a foundation for the development of a full-hydraulic transplanting machine to multi-functionalization.

Abstract

A hydraulic system of a fully hydraulic rice transplanter, comprising a fuel tank (15), a fuel pump, several solenoid valves, and several motors. The system comprises a front-wheel drive oil-way, a rear-wheel drive oil-way, and a transplanting oil-way. The front-wheel drive oil-way is connected to two front-wheel drive motors (1). The two front-wheel drive motors (1) have arranged therebetween a synchronous valve (3). The rear-wheel drive oil-way is connected to two rear-wheel drive motors (2). The two rear-wheel drive motors (2) also have arranged therebetween a synchronous valve (3). The transplanting oil-way is connected to a transplanting motor. The hydraulic system has the characteristics of a simplified structure, light weight, convenient layout, low failure rate, and reduced maintenance costs, and the transplanter lays a foundation for development towards multi-functionality.

Abstract

A fully hydraulic drive two-dimensional translation lifting/lowering-type agricultural vehicle frame. Same is constituted by a bottom frame (1-2), a translational frame (1-1), and a hydraulic drive system. The bottom frame (1-2) is constituted by a left-side beam (1-21) and a right-side beam (1-22). The translational frame (1-1) is a frame-type structure. The left-side beam (1-21) and the right-side beam (1-22) respectively are connected to the translational frame via two rocking columns. The rocking columns respectively are pivotally connected both to the left- and right-side beams and to the translational frame. The rocking columns are divided into front rocking columns (1-4) and rear rocking columns (1-3). The left- and right-side rear rocking columns respectively are connected to a jacking hydraulic cylinder (1-6). The jacking hydraulic cylinder is pivotally connected respectively to the left-side beam and to the right-side beam. The translational frame is provided at the rear part thereof with a connection mechanism that can be connected to a rice transplanter and a pesticide spraying machine. The agricultural vehicle frame has the characteristics of a simplified structure, convenient use, light-weight drive system, convenient layout, low failure rate, and reduced maintenance costs.

Abstract

A dual-purpose frame of a field operating vehicle, comprising an under frame (1-2) and a lifting frame (1-1). The under frame (1-2) is connected to wheels (1-6) and connected to the lifting frame (1-1) through a lifting mechanism. The under frame comprises a left side beam and a right side beam. The lifting frame is a frame structure comprising a side beam and a transverse beam. The lifting frame is provided with a connection apparatus used for switching and connecting a field maintenance machine and a rice tansplanter. The dual-purpose frame can be separately used as the rice transplanter and the field maintenance machine, and is simple in structure and convenient to operate.

Abstract

Disclosed is an adjustable asynchronous transplanting mechanism, comprising a seedling bed support, a seedling supply bed, several transplanting drive boxes (1), rotary boxes (2), and transplanting arms (3), wherein the seedling supply bed comprises several seedling troughs (4), and the seedling supply bed is adapted to a seedling bed guide rail (51) provided on the seedling bed support. A left-hand and a right-hand rotary box (2) are provided on each transplanting drive box (1), and two transplanting arms (3) are provided on the rotary boxes (2), wherein the right-hand rotary box (2) is provided with an angle adjustment mechanism for adjusting the angular difference of the left-hand and right-hand rotary boxes. A spacing adjustment can be made between a seedling trough (4) and another seedling trough (4) and between seedling removal ports (10). The rotary boxes (2) are provided with an axial adjustment mechanism making the transplanting arms (3) correspond to the seedling removal ports (10).
