The current promotion of multi-functional land preparation technology is achieved by using large-scale tractors equipped with multi-functional land preparation machines. Using this technology, the crew can complete operations such as extermination, rotary tillage, fertilization, ridging, and suppression all at once, which is very popular among farmers. However, due to the multiple functions and complicated structure of the multifunctional soil preparation machine, the adjustment in the operation is time-consuming, such as the adjustment of depth, ridge spacing, and crossover ridges. If these adjustments are made at least one hour at a time, the operation time is wasted and the operation time is increased. Labor intensity. In response to these problems, people of insight have come up with new ideas - use of the hydraulic system of the tractor instead of manual adjustment, that is, the use of three control valves by the pilot to control the three hydraulic cylinders, respectively, for the depth of cultivation, ridge distance and transfer The adjustment of ridges is as follows:
First, the adjustment of cultivation. Install a ground in the middle part of the rear beam of the multi-purpose preparation machine, and then connect a hydraulic cylinder to the floor lifting rod. The cylinder is fixed on the multi-functional machine, and the adjustment of the depth of cultivation is completed by changing the height of the cylinder by the cylinder.
Second, the ridge spacing adjustment. Four square sets are installed on the rear beam of the multi-functional preparation machine, and four ridge scoops are respectively fixed on the square sets, and then a hydraulic cylinder is connected to the square set through the transmission components, the cylinder is fixed on the multi-functional machine, and the cylinder is controlled by the cylinder. The transmission component changes the lateral position of the ridge scoop and completes the adjustment of the ridge pitch.
Third, the handover ridge adjustment. A hydraulic cylinder is installed in the middle of the left and right pull rods of the tractor suspension to control the lateral position of the complete machine and complete the adjustment of the crossover ridges.
