Technical Field

[0001] This utility model relates to the field of rotary tiller technology, specifically a rotary tiller with a mud-proof structure. Background Technology

[0002] A rotary tiller is a high-efficiency agricultural machine, a type of tillage machine used in conjunction with a tractor. It mainly uses the power output from the tractor to drive the rotary tiller blades to rotate, thereby cutting, mixing, and crushing the soil, improving agricultural production efficiency and reducing labor costs.

[0003] Patent document CN218784071U discloses a deep-till rotary tiller, which "involves the field of rotary tiller technology, including a mounting cover, with sliding groove seats fixed on both sides of the top of the inner wall of the mounting cover, and sliders sliding inside the two sliding groove seats. A horizontal electric hydraulic cylinder is fixed on one side of the inner wall of the two sliding groove seats, and the output ends of the two horizontal electric hydraulic cylinders are respectively fixedly connected to one side of the corresponding slider. The beneficial effect of this utility model is that the output ends of the two horizontal electric hydraulic cylinders are controlled to extend and retract, driving the two sliders to move laterally by sliding with the corresponding sliding groove seats. The lateral movement of the sliders drives the two drive motors and the two rotary tiller blades to move laterally through two support plates, two rotating shafts and two U-shaped arms. The output shafts of the three drive motors are controlled to rotate, driving the three rotary tiller blades to rotate, which facilitates the adjustment of the tillage area by adjusting the distance between the multiple rotary tiller blades."

The inner wall of the rotary tiller is provided with a hemispherical groove 21. Existing rotary tillers often cause soil splashing when turning the soil during operation, so this needs to be improved. First, the length of the mudguard 14 is changed according to requirements. Then, the splicing block 22 is moved into the splicing groove 15, the spring 19 is compressed, and the sleeve rod 18 moves in the sleeve 17. When the hemispherical block 20 moves below the hemispherical groove 21, the spring 19 returns to its original position, locking the hemispherical block 20 into the hemispherical groove 21. Then, the extension plate 24 is spliced ​​with the mudguard 14, and the length of the mudguard 14 is adjusted. Mudslide 14 will not fall off. The mud hits the mudguard 14 upwards. The extension plate 24 needs to be manually pulled left and right to be disassembled. The extension plate 24 will not fall off during the mud-blocking process. The sealing plug 16 is used to seal the splicing groove 15 when the extension plate 24 is not installed. Then, the adjusting motor 8 drives the threaded screw 10 to rotate. The limit rod 12 moves on the slip ring 11, which drives the mudguard 14 to adjust up and down. Then, the angle motor 13 drives the angle of the mudguard 14 to adjust to a suitable position, and the mudguard 14 is used to block the mud.

[0030] Please see Figure 5 and Figure 6The main support plate 1 has a maintenance mechanism on its top for wetting the soil. The maintenance mechanism includes a rainwater collection box 28, a spray plate 31, and a protective mechanism. The protective mechanism includes a first adhesive plate 25, a second adhesive plate 26, and a protective pad 27. The first adhesive plate 25 is located at the bottom of the mudguard 14, and the second adhesive plate 26 is located on the outer wall of the first adhesive plate 25. The outer wall of the second adhesive plate 26 is fitted with the protective pad 27. The rainwater collection box 28 is located on the top of the main support plate 1. A water pump 29 is installed on the top of the main support plate 1, with its inlet extending into the rainwater collection box 28. A hose 30 is installed at the outlet of the water pump 29. An electric telescopic rod 33 is installed on the top of the main support plate 1, with its output end fitted with... There is a spray plate 31, and multiple spray heads 32 are installed at the bottom of the spray plate 31. One end of the hose 30 extends into the interior of the spray plate 31. The existing rotary tiller cannot irrigate the turned soil, so this needs to be improved. The rainwater collection box 28 can collect rainwater from the outside or add water manually. The water pump 29 works to supply water to the spray plate 31 through the hose 30, and the spray heads 32 are used to irrigate the soil. At the same time, the electric telescopic rod 33 is used to adjust the position of the spray plate 31. If the extension plate 24 is installed, the spray plate 31 needs to be moved to the end of the edge of the extension plate 24 for spraying. The protective pad 27 is installed through the first adhesive plate 25 and the second adhesive plate 26. The protective pad 27 is used to protect the mudguard 14.

[0031] Working principle: The rotary tiller is connected to the tractor via assembly plate 7. The power output from the tractor drives the rotary tiller motor 5, which in turn rotates the rotary tiller blades 6 to turn the soil. The adjusting lever 3 moves the rotary tiller blades 4, adjusting the position of the blades 6 vertically to further break up soil clods and complete the tillage operation. However, existing rotary tillers often cause soil to splash during operation, so improvements are needed. Firstly, the length of the mudguard 14 is changed according to requirements. When the splicing block 22 is moved into the splicing groove 15, the spring 19 is compressed, and the sleeve rod 18 moves in the sleeve 17. When the hemispherical block 20 moves below the hemispherical groove 21, the spring 19 returns to its original position, locking the hemispherical block 20 into the hemispherical groove 21. This splices the extension plate 24 with the mudguard 14, adjusting the length of the mudguard 14. The extension plate 24 will not fall off, and the mud will hit the mudguard 14 upwards. The extension plate 24 can be disassembled manually by pulling it left and right, and will not cause mud to fall off during the mudguarding process. In the event of the extension plate 24 detaching, the sealing plug 16 seals the splicing groove 15 when the extension plate 24 is not installed. Then, the adjusting motor 8 drives the threaded screw 10 to rotate, causing the limit rod 12 to move on the slip ring 11, which in turn adjusts the mudguard 14 up and down. Subsequently, the angle motor 13 adjusts the angle of the mudguard 14 to a suitable position, thus using the mudguard 14 to shield the soil. Existing rotary tillers cannot irrigate the turned soil, therefore improvements are needed. The rainwater collection box 28 can... The water pump 29 works to supply water to the spray plate 31 through the hose 30 to collect rainwater from the outside or add water manually. The spray head 32 is then used to irrigate the soil. At the same time, the electric telescopic rod 33 is used to adjust the position of the spray plate 31. If the extension plate 24 is installed, the spray plate 31 needs to be moved to the end of the edge of the extension plate 24 for spraying. The protective pad 27 is installed through the first adhesive plate 25 and the second adhesive plate 26. The protective pad 27 is used to protect the mudguard 14.

[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
