Description

Technical Field

[0002] Tilling of agricultural land is an important part of agricultural production, which aims to improve soil structure, increase soil aeration, promote water penetration and nutrient distribution, and also help control weeds and pests. The existing tillage methods are mainly manual tillage and mechanical tillage. Manual tillage mainly uses tools such as hoes and shovels to turn the soil, which is suitable for small areas of cultivated land or fine operations. Mechanical tillage is done by using agricultural machinery such as plows and rotary tillers. It is efficient and suitable for large areas of cultivated land. Dog paddle tillers mainly use multiple claw-type cutters to push forward in the soil and automatically turn the soil. and loose soil, but the tillage depth required for different planting scenarios is indeed different. The tillage depth of dog paddle tillers is mostly fixed and has low flexibility. It is necessary to replace the tool to control the digging depth, which increases the workload of workers. Secondly, when the dog paddle tiller is turning the soil with fine clay texture and small particles, the soil is easy to agglomerate in the moist environment after turning the soil to form larger lumps, which will cause a series of impacts on the subsequent planting of crops.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1.

If the dog-paddle tilling device 5 tills the soil and there are large blocks of agglomeration, the turning plate 2 is turned by the turning adjustment mechanism 7 so that the tilling and crushing assembly 9 contacts the tilled soil blocks; S3, during the process of the overturning plate 2 driven by the overturning adjustment mechanism 7, the plowing and crushing assembly 9 is connected to the dog-paddle type plowing device 5 through the synchronous transmission assembly 8, so that the dog-paddle type plowing device 5 drives the plowing and crushing assembly 9 to run synchronously while running; S4, the dog-paddle tillage device 5 lifts the tilled soil upwards and contacts the rotating crushing frame 906 under the action of the guide plate, and the rotating crushing frame 906 rotates and cooperates with the fixed frame 904 to crush the larger soil blocks into small pieces; S5. When the tilling depth needs to be adjusted, the eccentric wheel 402 is driven to rotate by the tilling depth adjustment component 4, and the position of the crankshaft 403 is adjusted by the eccentric wheel 402, thereby adjusting the tilling depth of the dog paddle tilling device 5.

[0035] Working principle: First, the external traction device drives the agricultural land turning device to move to the land to be turned. Fig.10 As shown, the second motor 507 is controlled to be turned on, and the driving end of the second motor 507 drives the driving shaft 506 to rotate through the pulley transmission group, and the driving shaft 506 drives the transmission shaft 512 to rotate through the synchronous wheel transmission group. The transmission shaft 512 drives the crankshaft 403 to rotate through the first universal joint 508, the first fixed shaft 509, the first sliding shaft 510 and the second universal joint 511. During the rotation of the crankshaft 403, the plowing plate 505 is driven to move through the connecting rod 503 and the driven rod 504, and the soil is dug up by the plowing plate 505 for plowing. When the driving shaft 506 rotates, it drives the main shaft 801 to rotate through the bevel gear group, as shown in FIG. Fig.12 As shown, at this time, the conical friction block 802 and the friction frame 805 are tightly fitted, the main shaft 801 drives the secondary shaft 804 to rotate through the conical friction block 802 and the friction frame 805, the secondary shaft 804 drives the connecting shaft 902 to rotate through the third universal joint 809, the second sliding shaft 810, the second fixed shaft 811 and the fourth universal joint 812, the connecting shaft 902 drives the intermediate driven shaft 903 to rotate synchronously through the conical gear set, the intermediate driven shaft 903 drives the driven shafts 903 on both sides to rotate synchronously through the synchronous wheel transmission group, the driven shaft 903 drives the rotating crushing frame 906 to rotate through the rotating base 905, the soil blocks turned up by the plowing plate 505 fall between the rotating crushing frame 906 and the fixed frame 904 under the action of the guide plate, and as the rotating crushing frame 906 rotates and cooperates with the fixed frame 904 to crush the larger soil blocks, when it is necessary to adjust the plowing depth of the plowing plate 505, as shown in FIG. Figure 5 As shown, the first motor 409 is controlled to start and drive the drive shaft 406 to rotate clockwise through the pulley transmission group. The drive shaft 406 drives the eccentric wheel 402 to rotate clockwise synchronously through the rotating rod 407, the first arc rod 408, and the connecting frame 404. The eccentric wheel 402 is rotated to adjust the position of the crankshaft 403 to change the plowing track of the plowing plate 505, so as to achieve the effect of adjusting the plowing depth. When it is not necessary to break the plowed soil blocks, as shown in FIG. Fig.12 As shown, the driving end of the control electric cylinder 710 contracts and drives the rack 703 to move to the left under the guidance of the first slide rail 702 through the connecting frame 709. During the movement, the rack 703 drives the rotating shaft 704 to rotate counterclockwise by rotating the gear 705, as shown in FIG. Fig.13As shown, the rotating shaft 704 drives the flip plate 2 to flip through the rotating frame 706, the second arc rod 707 and the guide bolt 708 to separate the rotating crushing frame 906 from the cultivated land. During this process, the connecting frame 709 drives the paddle 808 to move synchronously to the left under the guidance of the second slide rail 807. During the movement, the paddle 808 drives the conical friction block 802 to move synchronously through the sliding ring 803, so that the conical friction block 802 is separated from the friction frame 805. The main shaft 801 stops driving the secondary shaft 804 to rotate, so that the plowing and crushing assembly 9 stops running, and the second motor 507 only drives the dog paddle plowing device 5 to run.

Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
