本发明在使用中， 通过两个前轮驱动马达和两个后轮驱动马达各自独立驱 动车轮， 形成四驱结构， 两前轮驱动马达之间以及两后轮驱动马达之间设有的 同步阀保证了在前进或者倒退过程中， 左右侧车轮之间的同步性。 同时， 由于 在插秧机在转向过程中， 左右车轮之间对油路***的反作用力不同， 正好通过 同步阀的平衡作用， 使得其实现转弯时的内侧轮转速慢于外侧轮， 达到流畅、 灵活的转弯效果， 前后轮驱动油路的回油均通过插植油路， 利用前、 后轮驱动 油路的回油， 驱动插植机构工作， 当该三位四通换向阀处于中位时， 前、 后轮 的进油和回油油路直接接通， 前、 后轮驱动马达停止工作， 此时， 该液压油路 可以驱动插植机构工作。 本发明利用前后轮驱动油路的回油驱动插植机构， 一 方面简化了插植机构的工作油路， 另一方面， 这种方式实现了插植机构与车轮 行走的联动， 并保证了它们之间的比例关系。 在不同的路面上行走时， 还可以 通过调整前轮驱动油路或后轮驱动油路上的三位四通换向阀切换切轮驱动或后 轮驱动。 高速档是插秧机不作业， 在路面上行走的档位， 低速档是插秧机在作 业时的档位。 当高低压切换阀驱动端口通过油控切换阀与提升油路的进油端相 连时， 即可驱动高低压切换阀动作， 进而驱动上述液压缸动作， 使其带动高低 速档调节开关动作， 使得前、 后轮驱动马达进入高速转动， 反之， 当高低压切 换阀驱动端口通过油控切换阀与转向油路、 前轮驱动油路、 后轮驱动油路以及 插植油路的出油端相连时， 前、 后轮驱动马达进入低速转动。  In use, the present invention independently drives the wheels by two front wheel drive motors and two rear wheel drive motors to form a four-wheel drive structure, a synchronizing valve disposed between the two front wheel drive motors and between the two rear wheel drive motors. Synchronization between the left and right wheels during forward or reverse is guaranteed. At the same time, because the reaction force between the left and right wheels on the oil circuit system is different during the turning process, the balance of the synchronous valve is justified, so that the inner wheel rotation speed when the turning is slower than the outer wheel is smooth and flexible. The turning effect, the oil return of the front and rear wheel drive oil passages are all inserted into the planting oil road, and the oil returning is driven by the front and rear wheels to drive the planting mechanism, when the three-position four-way reversing valve is in the middle position The oil inlet and return oil lines of the front and rear wheels are directly connected, and the front and rear wheel drive motors are stopped. At this time, the hydraulic oil circuit can drive the planting mechanism to work. The invention utilizes the oil return driving planting mechanism of the front and rear wheel drive oil passages, on the one hand, simplifies the working oil passage of the planting mechanism, on the other hand, the linkage mechanism between the planting mechanism and the wheel walking is realized, and the same is ensured. The proportional relationship between. When walking on different roads, it is also possible to switch the cutter drive or rear wheel drive by adjusting the three-position four-way selector valve on the front wheel drive oil or the rear wheel drive oil line. The high-speed gear is the gear that does not work in the rice transplanter, and the gear that travels on the road. The low-speed gear is the gear position of the rice transplanter during the work. When the high and low pressure switching valve drive port is connected to the oil inlet end of the lift oil passage through the oil control switching valve, the high and low pressure switching valve can be driven to drive the hydraulic cylinder to operate, so that the high and low speed adjustment switch acts, thereby making The front and rear wheel drive motors enter high speed rotation. Conversely, when the high and low pressure switch valve drive port is connected to the steering oil circuit, the front wheel drive oil circuit, the rear wheel drive oil circuit and the oil discharge end of the planting oil passage through the oil control switching valve When the front and rear wheel drive motors enter a low speed rotation.
所以本发明具有结构简单、 重最轻、 布局方便、 故障率低、 维护成本低等 特点。  Therefore, the invention has the characteristics of simple structure, lightest weight, convenient layout, low failure rate and low maintenance cost.
