[0016] The crop cultivation machine provided by the utility model is described in detail below with reference to the drawings and in combination with an embodiment.

[0017] Embodiment

[0018] With reference to Figures 1-3 The power traction mechanism of the crop cultivation machine of the embodiment is tractor traction power. The tractor comprises a front frame and engine mounting rack welding group 3, a front wheel and steering group 4, a rear axle frame gearbox rotary cultivator assembly 2, a rear frame 1, a positive and negative wire connecting rod 5, an oil cylinder 6, and an engine 8. The front wheel and steering group is installed at the front of the front frame and engine mounting rack welding group. The rear frame is connected to the rear of the front frame and engine mounting rack welding group. The rear frame comprises a sliding outer tube 1-1. The front frame and engine mounting rack welding group comprises a front frame 3-1, an engine mounting rack 3-2, and a sliding inner tube 3-1-1. The engine is mounted on the engine mounting rack. The engine mounting rack is mounted on the sliding outer tube. The sliding outer tube is sleeved outside the sliding inner tube. The rear axle frame gearbox rotary cultivator assembly comprises a rear wheel group 2-1, a gearbox 2-2, a cultivation tool 2-3, a fixed tube 2-4, and a height adjustment connecting device 2-5. The gearbox is hinged to the rear frame. The gearbox is in transmission connection with the engine through a V-shaped belt 7 and moves synchronously. The gearbox is connected to the cultivation tool and the rear wheel group. The cultivation tool is any one of a rotary cultivator, a stubble cleaner, a furrower, a ridge lifter, a weeder, a grape burying machine, a seeder, and a fertilizer applicator.

[0019] The fixed tube is welded to the gearbox. The height adjustment connecting device is fixed to the upper part of the fixed tube. The height adjustment connecting device is a telescopic tube which is sleeved inside the fixed tube. Specifically, nuts are welded to the fixed tube 2-4 and are matched with jam nuts. The telescopic tube 2-5 can slide up and down in the fixed tube 2-4 and can be locked by the jam nuts, thereby adjusting the height.

[0020] The sliding outer tube is provided with a sliding outer tube long slot inside. The bottom of the engine mounting rack is installed in the sliding outer tube long slot. The sliding outer tube long slot is used for guiding and limiting the mounting rack. The bottom of the engine mounting rack is provided with an oil cylinder. The output end of the oil cylinder is hinged to the gearbox.

[0021] The positive and negative wire connecting rod is hinged to the height adjustment connecting device at the upper part of the fixed tube. The other end of the positive and negative wire connecting rod is hinged to the rear side of the engine mounting rack.

[0022] With reference to Figure 4The height adjusting connecting device adopts a long-hole channel steel fixed on the outside of the fixed square tube, the fixed square tube B-1 and the long-hole channel steel B-2 are welded together, the bolt can slide in the long hole, and the nut can be locked to realize height adjustment.

[0023] When the crop cultivation machine is working, the cultivation machine to be used is selected, and the machine is hung on the rear of the gearbox or extended into the rear of the gearbox according to the structure of the machine and connected by bolts. After the machine is installed, the tractor is started to drive the machine to work and move forward. When the oil cylinder is retracted, the engine mounting frame moves backward, the gearbox rotates downward through the driving of the positive and negative silk connecting rod and V-shaped belt, and drives the connected cultivation machine to move downward to work on the ground. Conversely, after the work is completed, the oil cylinder is extended, the engine mounting frame connected thereto moves forward, the gearbox drives the connected cultivation machine to move upward through the driving of the positive and negative silk connecting rod and V-shaped belt, and the steering wheel controls the direction of the tractor. The oil cylinder continuously repeats extension and retraction during the movement of the tractor until the work is completed.

[0024] By adjusting the height of the telescopic square tube and the length of the positive and negative silk connecting rod, the tension of the V-shaped belt will not change greatly when the oil cylinder is extended and compressed, which ensures the realization of the function of the overall mechanism.

[0025] The three-wheeled tractor is directly connected with the cultivation machine, has a simple structure, small size and light weight, and can conveniently cultivate small fields. The tractor is an existing tractor, and the engine, gearbox and other components on the tractor are standard components of the existing tractor. Therefore, the maintenance technology is mature after failure, and the replacement can be conveniently purchased, so that the long maintenance period caused by mechanical failure does not affect the use in season. The maintenance cost of the standard components is low, which reduces the use cost of the product.
