Description

Technical Field

[0001] This utility model relates to the field of land tillage technology, specifically a land tillage device. Background Technology

[0002] After the autumn harvest, in order to increase soil aeration and water permeability and provide good soil conditions for spring sowing, it is necessary to use tillage equipment to loosen the soil.

[0003] A search revealed a Chinese patent (CN221728831U) that discloses a land tillage device. By setting a rotating shaft and a loosening hoe, the land can be tilled and loosened before plowing. The land is then plowed with a plowshare that is larger at the bottom and smaller at the top. Although this device can till the land, it cannot remove stones from the soil. When planting crops, these stones can affect the development of the crop roots and nutrient absorption. Therefore, we propose a land tillage device. Utility Model Content

[0004] The technical problem this application aims to solve is: the inability to remove stones from the soil, which can affect the development of crop roots and nutrient absorption when planting crops.

[0005] To solve the above-mentioned technical problems, this application provides a land tillage device, including a mounting plate, a hydraulic cylinder mounted on the top of the mounting plate, a base plate connected to the output end of the hydraulic cylinder extending from the bottom of the mounting plate, a fixing plate mounted on both ends of the bottom of the base plate, a rotary tiller rotatably mounted on the lower end of one fixing plate, and multiple rotary tillers arrayed on the outer side of the rotary tiller for preliminary tillage of the soil.

[0006] A grid cylinder is rotatably mounted on the lower end of the fixed plate at the other end for further loosening the soil after tilling. Multiple elastic steel wires are evenly installed in the grid holes of the grid cylinder to intercept stones in the soil.

[0007] In some embodiments, a drain hole communicating with the interior of the grid cylinder is provided on one side of the grid cylinder, and a baffle adapted to the size of the drain hole is slidably connected inside the grid cylinder.

[0008] In some embodiments, a slide rod is slidably connected to one side of the baffle, a pull rod extending out of the drain hole is installed at one end of the slide rod, and a groove is provided at the other end of the slide rod. A positioning block is slidably connected inside the groove, and a limit spring is elastically connected between the positioning block and the groove. The side of the positioning block extending out of the groove is provided with an inclined surface that slopes towards the pull rod, and a positioning groove adapted to the size of the positioning block is provided on one side of the grid cylinder.

[0009] In some embodiments, a motor is installed at the upper end of one end of the fixed plate, and a first pulley is rotatably installed at both the upper and lower ends inside the fixed plate. The upper first pulley is connected to the output end of the motor, and the lower first pulley is connected to one side of the rotary tiller. A first belt is tensioned and sleeved on the outer side of the upper and lower first pulleys.

[0010] In some embodiments, the lower ends of the fixed plates at both ends are connected to a connecting plate, and the two ends inside the connecting plate are rotatably mounted with a second pulley. One end of the second pulley is connected to the lower end of the first pulley, and the other end of the second pulley is connected to one side of the grid cylinder. The outer sides of the two ends of the second pulley are tensioned with a second belt.

[0011] In some embodiments, a drawbar for connection to an external tractor is mounted on one end of the mounting plate.

[0012] In some embodiments, two wheels are rotatably mounted on the bottom of the mounting plate away from the tow bar.

[0013] This utility model has at least the following beneficial effects:

[0014] The soil is initially tilled using rotary tillers and blades. The addition of grid cylinders and elastic steel wires further loosens the soil as the grid cylinders pass through it, improving the tilling effect. During the loosening process, stones in the soil compress the elastic steel wires, causing them to deform. The stones then pass through the gaps in the elastic steel wires and enter the cavities of the grid cylinders and elastic steel wires, thus collecting the stones and preventing them from affecting the development of crop roots and nutrient absorption during subsequent planting.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1

[0026] Please see Figure 1-5 This utility model provides a technical solution: a land tillage device, including a mounting plate 1. One end of the mounting plate 1 is equipped with a traction rod 101 that connects to an external tractor. The traction rod 101 connects the mounting plate 1 to the external tractor, and the external tractor drives the entire device to move. Two wheels 102 are rotatably mounted on the bottom end of the mounting plate 1 away from the traction rod 101. The wheels 102 are larger in diameter than the rotary tiller 5 and the grid cylinder 6 to prevent the rotary tiller 5 and the grid cylinder 6 from contacting the ground during movement. A hydraulic cylinder 2 is mounted on the top of the mounting plate 1. The hydraulic cylinder 2 raises and lowers the rotary tiller 5 and the grid cylinder 6, thereby adjusting the tillage depth. The output end of the hydraulic cylinder 2 extending from the bottom of the mounting plate 1 is connected to a base plate 3. Fixing plates 4 are mounted on both ends of the bottom of the base plate 3. A rotary tiller 5 is rotatably mounted on the lower end of one fixing plate 4. Multiple rotary tillage blades are arrayed on the outer side of the rotary tiller 5 for preliminary tillage of the soil.

[0027] Furthermore, a motor 13 is installed on the upper end of one end fixing plate 4, and a first pulley 14 is rotatably installed on both the upper and lower ends inside the one end fixing plate 4. The upper first pulley 14 is connected to the output end of the motor 13, and the lower first pulley 14 is connected to one side of the rotary tiller 5. A first belt 15 is tensioned and sleeved on the outer side of the upper and lower first pulleys 14.

[0028] The lower ends of the two fixed plates 4 are connected to the connecting plate 16. The two ends of the connecting plate 16 are rotatably installed with the second pulley 17. One end of the second pulley 17 is connected to the lower end of the first pulley 14, and the other end of the second pulley 17 is connected to one side of the grid cylinder 6. The outer sides of the two end second pulleys 17 are tensioned with the second belt 18.

[0029] The grid cylinder 6 is rotatably installed at the lower end of the fixing plate 4 at the other end for further loosening the soil after tilling. Multiple elastic steel wires 7 are evenly installed in the grid holes of the grid cylinder 6 to intercept stones in the soil.

[0030] In use, the motor 13 is started, which drives the upper first pulley 14 to rotate. Through the first belt 15 and the lower first pulley 14, the rotary tiller 5 is rotated, achieving initial tillage of the soil by the rotary tiller blades. When the lower first pulley 14 rotates, it drives the second pulley 17 at one end to rotate. The second pulley 17 at one end drives the grid cylinder 6 to rotate through the second belt 18 and the second pulley 17 at the other end, achieving further loosening of the tilled soil by the grid cylinder 6. The grid cylinder 6 drives the elastic steel wire 7 to rotate. The elastic steel wire 7 comes into contact with stones in the soil and deforms after being squeezed. The stones enter the cavity of the grid cylinder 6 and the elastic steel wire 7 through the gaps in the elastic steel wire 7, thereby achieving the collection of stones.

[0031] Furthermore, a perforation 601 communicating with the interior of the grid cylinder 6 is provided on one side, and a baffle 8 that matches the size of the perforation 601 is slidably connected inside the grid cylinder 6.

[0032] A slide rod 9 is slidably connected to one side of the baffle 8. A pull rod 10 extending out of the drain hole 601 is installed at one end of the slide rod 9. A groove 901 is provided at the other end of the slide rod 9. A positioning block 11 is slidably connected inside the groove 901. A limit spring 12 is elastically connected between the positioning block 11 and the groove 901. The side of the positioning block 11 extending out of the groove 901 is provided with an inclined surface that slopes towards the pull rod 10. A positioning groove 602 that matches the size of the positioning block 11 is provided on one side of the grid cylinder 6.

[0033] When it is necessary to remove stones from the cavity of the grid cylinder 6 and the elastic steel wire 7, slide the pull rod 10 away from the end of the positioning block 11. The pull rod 10 drives the slide rod 9, the positioning block 11 and the limiting spring 12 to slide. The inclined surface of the positioning block 11 is squeezed by the positioning groove 602 of the grid cylinder 6, slides into the groove 901 and squeezes the limiting spring 12, thereby releasing the limit of the baffle 8 and allowing the baffle 8 to slide open the leakage hole 601 of the grid cylinder 6. At this time, the stones can be taken out from the leakage hole 601, avoiding the stones from affecting the development of crop roots and nutrient absorption in the soil.

[0034] Example 2

[0035] Please see Figure 6-8 This utility model provides a technical solution: Based on embodiment 1, this utility model provides another technical solution: A storage box 19 is also installed on the top of the mounting plate 1 for storing lime powder or base fertilizer. An adjusting plate 20 is slidably connected to the lower end of the storage box 19. One end of the adjusting plate 20 is inserted into the discharge port at the bottom of the storage box 19. A fixing block 1901 is symmetrically installed on the lower end of the storage box 19. A slider 2001 is symmetrically installed on the other end of the adjusting plate 20 located outside the storage box 19. A threaded rod 21 is installed on one end of the fixing block 1901. The slider 2001 is slidably sleeved on the outside of the threaded rod 21. Nuts 22 that fit with both ends of the slider 2001 are threadedly sleeved on the outside of the threaded rod 21. By adjusting the nuts 22 to limit the position of the slider 2001 on the threaded rod 21, the discharge amount of the discharge port can be adjusted. When tilling, lime powder or base fertilizer is poured into the soil through the discharge port to reduce pests and diseases and increase soil fertility.
