Embodiment 1

[0021] Such as figure 1 As shown, 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 include front wheels The drive motor 1 and the rear-wheel drive motor 2 are respectively connected with a steering column 23 on the axle of each wheel, and the steering column is connected with the steering system. The steering system includes a front-wheel steering oil passage and a rear-wheel steering oil passage. The front-wheel steering oil passage is connected with the two front-wheel steering columns 23, and the rear-wheel steering oil passage is connected with the two rear-wheel steering columns 22.

[0022] When the present invention is in use, each wheel is driven by a driving motor, and the front and rear wheels are driven simultaneously or alternately, so that the power is strong, the op...

Embodiment 2

[0024] Such as figure 1 , figure 2 As shown, the present invention is based on embodiment 1, 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 rear wheels turn to the oil circuit. A lifting pump 12 is provided on the lifting oil passage of the planting part, and the lifting oil passage of the planting part is connected with the lifting oil cylinder 14. The front-wheel drive oil circuit is connected to two front-wheel drive motors 1. A synchronization valve 3 is provided 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 to two rear-wheel drive motors 2, and a synchronization valve 3 is also provided between the two rear-wheel drive motors 2, and the two output ends of the synchronization v...

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

[0001] Technical field [0002] The invention relates to a rice transplanter, in particular to a four-wheel drive rice transplanter. [0003] Background technique [0004] Rice transplanter is the most important and one of the most commonly used agricultural machinery. When the rice transplanter is working, it needs to work in muddy soil conditions, so the resistance when turning is very large. In addition, when transplanting seedlings, it is necessary to accurately enter the corresponding area for operation, and during the operation, the area needs to be changed, and the conversion process needs to be accurate and timely to ensure uniform and high efficiency of transplanting. Therefore, due to the limitation of the existing mechanical transmission, the steering system of the existing rice transplanter generally adopts a single front wheel or a single rear wheel as the guide wheel for steering. The steering radius is relatively large, and the steering flexibility is poor. Existin...
