Embodiment 1

[0017] like figure 1 As shown in the figure, the present invention is a full four-wheel guided rice transplanter, including a planting mechanism, a hydraulic drive system, and a frame. The frame is provided with wheels, and the wheels are respectively provided with a corresponding drive motor, and includes a front wheel. The axles of the drive motor 1 and the rear-wheel drive motor 2 are respectively connected with a steering column 23, which is connected with the steering system. The steering system includes a front wheel steering oil circuit and a rear wheel steering oil circuit. The front wheel steering oil circuit is connected with the steering columns 23 of the two front wheels, and the rear wheel steering oil circuit is connected with the steering columns 22 of the two rear wheels.

[0018]When the present invention is in use, each wheel is driven by a driving motor, and the front and rear wheels are simultaneously or alternately driven, so that it has strong power and f...

Embodiment 2

[0020] like figure 1 , figure 2 As shown, the present invention is based on Embodiment 1, and the hydraulic drive system includes a front wheel drive oil circuit, a rear wheel drive oil circuit, a planting oil circuit, a planting part lifting oil circuit, and the front wheel steering oil circuit and the The rear wheels are steered to the oil circuit. A lift pump 12 is provided on the lifting oil circuit of the planting part, and the lifting oil circuit of the planting part is connected with the lifting oil cylinder 14 . The front wheel drive oil circuit is connected with the two front wheel drive motors 1, a synchronization valve 3 is arranged between the two front wheel drive motors 1, and the two output ends of the synchronization valve 3 are connected by an on-off valve 21, The rear-wheel drive oil circuit is connected with the two rear-wheel drive motors 2, and a synchronization valve 3 is also arranged between the two rear-wheel drive motors 2, and the two output ends ...

Abstract

The invention relates to an all-four-wheel guiding transplanter. The all-four-wheel guiding transplanter comprises a planting mechanism, a hydraulic driving system and a frame, wherein wheels are arranged under the frame and are respectively provided with a corresponding driving motor; a wheel shaft of each wheel is connected with a steering vertical column; and the steering vertical columns are connected with a steering system. The all-four-wheel guiding transplanter can be in place accurately, flexibly, smoothly and immediately when a working area is changed.

Description

technical field [0001] The invention relates to a rice transplanter, in particular to a four-wheel drive rice transplanter. Background technique [0002] Rice transplanter is one of the most important and most commonly used agricultural machinery. When the rice transplanter works, it needs to work in muddy soil conditions, so the resistance when it is turned is very large. In addition, when transplanting rice, it is necessary to accurately enter the corresponding area for operation, and during the operation, it is necessary to change the area, and the conversion process needs to be accurate and timely to ensure uniform and high efficiency of rice transplanting. Therefore, due to the limitation of the existing mechanical transmission, the steering system of the existing rice transplanter generally uses a single front wheel or a single rear wheel as a guide wheel for steering, which has a large steering radius and poor steering flexibility, which in turn causes The existing ...
