[0026] Among them, the gearbox 221 is arranged on the main machine frame 21 and is connected to the rotating shaft 222. The gearbox 221 is cast from high-strength nodular iron and contains large-module gears, making it have strong impact resistance, more reliable and more durable.

[0027] It should be noted that if the soil hardness or viscosity is too high, the rotation speed can be adjusted through the gearbox 221 to facilitate subsequent work.

[0028] The rotating shaft 222 is rotatably arranged on the main machine frame 21 and is located at the bottom of the main machine frame 21. A plurality of rotary tillage blades 223 are arranged in a circumferential manner on the surface of the rotating shaft 222. The fixing plate 224 is connected to the main machine frame 21 and is arranged on both sides of the rotating shaft 222.

[0029] It should be noted that the rotating shaft 222 drives the rotary tillage blades 223 to carry out rotary tillage and stubble elimination and soil crushing work on the land, and the land will be preliminarily prepared.

[0030] The leveling and pressing assembly 3 includes a connecting frame 31 and a leveling and pressing structure 32. The leveling and pressing structure 32 includes a reinforced soil leveling plate 321 and a heavy-duty rolling press 322.

[0031] Among them, the reinforced soil leveling plate 321 is connected to the fixing plate 224 and they have the same height. The heavy-duty rolling press 322 is connected to the reinforced soil leveling plate 321 and is located on the side away from the rotary tillage assembly 2.

[0032] It should be noted that when the heavy-duty rolling press 322 is started, the heavy-duty rolling press 322 cooperates with the reinforced soil leveling plate 321 to carry out soil leveling and pressing work on the land, improving the integrity of the device operation.

[0033] The drilling assembly 4 includes a hydraulic telescopic cylinder 41 and a drilling structure 42. The drilling structure 42 includes a first mounting frame 421, a seeding box 422, a driving wheel 423, a second mounting frame 424, a furrowing disc 425, a rolling press wheel 426, a soil covering frame 427 and a foot pedal 428.

[0034] Among them, the upper part of the first mounting frame 421 is connected to the hydraulic telescopic cylinder 41, and the lower part is connected to the connecting frame 31. The seeding box 422 is fixedly arranged on the top of the first mounting frame 421. The driving wheel 423 is rotatably arranged at the bottom of the first mounting frame 421. The second mounting frame 424 is connected to the first mounting frame 421 and extends towards the side away from the leveling and pressing assembly 3. The main machine frame 21, the connecting frame 31, the first mounting frame 421 and the second mounting frame 424 are all welded by high-strength alloy materials, mainly playing a role of support and fixation.

[0035] It should be noted that when necessary, the hydraulic telescopic cylinder 41 can be started to adjust the position of the drilling assembly 4, thereby changing the seeding depth, etc., improving the flexibility of the device.

[0036] The furrowing disc 425 is fixedly arranged at the bottom of the second mounting frame 424. The rolling press wheel 426 is arranged on the second mounting frame 424. The rolling press wheel 426 is close to the furrowing disc 425 and is located on the side away from the leveling and pressing assembly 3. The soil covering frame 427 is arranged on the rolling press wheel 426. The foot pedal 428 is arranged on the top of the second mounting frame 424.

[0037] It should be noted that the furrowing disc 425 will divide the flat and loose land into planting grooves convenient for planting. The seeds in the sowing box 422 will fall into the planting grooves. Then, the pressing wheel 426 will drive the soil covering frame 427, and the soil covering frame 427 will cover the planting grooves with soil.

[0038] Specifically, when relevant staff need to carry out relevant work, they can first open the fertilizer box 1 and the rotary tillage structure 22 at the same time. While the fertilizer box 1 spreads fertilizer on the land for fertilization, the rotary shaft 222 will drive the rotary tillage blades 223 to carry out rotary tillage stubble removal and soil crushing work on the land. The land will be preliminarily prepared. If the land hardness or viscosity is too high, the rotation speed can be adjusted through the gearbox 221 to facilitate subsequent work.

[0039] Then start the heavy pressing roller 322. The heavy pressing roller 322 will cooperate with the strengthened soil leveling plate 321 to carry out soil leveling and pressing work on the land. The land after being sorted by the leveling and pressing structure 32 will become flat, loose and rich in fertilizer, which is convenient for planting work.

[0040] Finally, start the driving wheel 423 to drive the device to move. The furrowing disc 425 will divide the flat and loose land into planting grooves convenient for planting. The seeds in the sowing box 422 will fall into the planting grooves. Then, the pressing wheel 426 will drive the soil covering frame 427, and the soil covering frame 427 will cover the planting grooves with soil. Thus, the whole set of planting operations is completed, which is convenient and fast.

[0041] In summary, for a rotary tiller and precision drill according to an embodiment of the present invention, through the fertilizer box and the rotary tillage assembly, fertilization, rotary tillage stubble removal and soil crushing work can be carried out on the land. Then, by further cooperating with the leveling and pressing assembly, soil leveling and pressing can be achieved, which is convenient for subsequent work. Finally, adding the precision drill assembly is convenient for achieving furrowing, sowing and soil covering work, saving time and ensuring work efficiency.
