Description

Technical Field

[0001] This utility model relates to the field of agricultural implements, and in particular to a soil protection device for agricultural tillage machines with an adjustable mud-blocking angle. Background Technology

[0002] With the advancement of agricultural modernization, agricultural machinery such as tractors, harvesters, and rotary tillers have become core equipment in agricultural production and are widely used in multiple stages such as tilling, sowing, fertilizing, and harvesting. When agricultural machinery is in operation, its tillage parts, such as plow blades and rotary tillage teeth, come into direct contact with the soil, which can cause a large amount of soil, gravel, weeds, etc. to be splashed.

[0003] These splashes not only contaminate the machine body, accelerating wear and corrosion and reducing its lifespan, but may also splash onto operators, affecting their safety and comfort. Furthermore, if the splashed soil falls into cultivated or sown areas, it may damage the topsoil structure or affect seed germination, reducing the quality of the work. Therefore, equipping agricultural machines with soil protection devices is a necessary measure to improve work efficiency and protect equipment and personnel.

[0004] Existing mudguard devices for agricultural machinery are mostly designed with a fixed angle, and the angle and position of the mudguard cannot be adjusted. They are only used for a single operating scenario. However, in actual agricultural production, agricultural machinery faces complex and varied operating conditions, and traditional fixed-angle mudguard devices have poor adaptability. Utility Model Content

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] Example 1, as Figure 1 and Figure 2 As shown, a soil protection device for a farm tiller with an adjustable mud-blocking angle includes a lifting component 1. A fixing component 2 is fixedly connected to one end of the lifting component 1. A mud-blocking component 3 is connected to the left side of the lifting component 1. The lifting component 1 includes a support 11. A rotating shaft 12 is rotatably connected to the inner surface of the support 11. The rear end of the rotating shaft 12 passes through the rotating shaft 12. Connecting plates 13 are fixedly connected to both sides of the right end of the support 11. Electric push rods 14 are provided on both sides of the upper end of the support 11. The output ends of the two electric push rods 14 are rotatably connected to the upper side of the support 11.

[0026] Furthermore, both connecting plates 13 are rotatably connected to the main body of the agricultural tiller, and both electric push rods 14 are rotatably connected to the main body of the agricultural tiller.

[0027] Connect the two connecting plates 13 to the tiller, and then install the two electric push rods 14 on both sides of the tiller. When it is necessary to adjust the height of the mudguard assembly 3, pull or push the support 11 through the electric push rods 14 to drive the support 11 and the mudguard assembly 3 to move up and down, thereby adjusting the height of the mudguard assembly 3.

[0028] like Figure 3 As shown, the fixing component 2 includes a fixing block 21 fixedly connected to the rear end of the support 11. A fixing rod 22 is fixedly connected to the left side of the inner surface of the fixing block 21, and a sliding rod 23 is slidably connected to the right side of the inner surface of the fixing block 21. A semi-circular groove 24 is provided on the side of the fixing rod 22 and the sliding rod 23 that are close to each other. A rotating housing 25 is threadedly connected to the right side of the fixing block 21. Both semi-circular grooves 24 are adapted to the shape of the rotating shaft 12.

[0029] In this embodiment, when it is necessary to rotate the mudguard assembly 3 to adjust its mudguard angle, the housing 25 is rotated so that the rotating housing 25 moves away from the fixed rod 22. Then, the sliding rod 23 is slid away from the fixed rod 22 to increase the distance between the sliding rod 23 and the fixed rod 22, thereby allowing the rotating shaft 12 to rotate. The rotating shaft 12 drives the mudguard assembly 3 to rotate, thus adjusting its angle.

[0030] After the adjustment is completed, rotate the housing 25 in the opposite direction so that the rotating housing 25 moves toward the sliding rod 23, pushing the sliding rod 23 to slide toward the rotating shaft 12, and then together with the fixing rod 22 clamp and fix the rotating shaft 12 to prevent the mudguard assembly 3 from rotating again;

[0031] The surfaces of both semicircular grooves 24 are covered with anti-slip layers to increase friction and provide a more stable fixation for the rotating shaft 12.

[0032] Example 2: Based on Example 1, this example adds a mudguard component 3, which can shield the mud splashed up by the tiller during operation, protect the tiller, and the length of the mudguard can be adjusted according to the size of the tiller to adapt to different types of tillers.

[0033] like Figure 4 As shown, the mudguard assembly 3 includes two fixed sleeves 31 fixedly connected to the outer surface of the rotating shaft 12. The two fixed sleeves 31 are fixedly connected to a plate 32. A rectangular hole 33 is opened on both sides of the upper end of the plate 32. A moving part 34 is slidably connected to both sides of the inner surface of the plate 32. A limiting part 35 is fixedly connected to both sides of the upper end of the plate 32.

[0034] like Figure 4 As shown, the moving part 34 includes a sliding plate 341 slidably connected to the middle of one side of the plate 32. The upper end of the sliding plate 341 is provided with a plurality of rectangular holes 342 arranged in a linear array. An arc plate 343 is fixedly connected to one end of the sliding plate 341 away from the middle of the plate 32.

[0035] Specifically, the shapes of the two rectangular holes 33 and the several rectangular holes 342 are all matched.

[0036] like Figure 5As shown, the limiting part 35 includes a fixed seat 351 fixedly connected to one side of the upper end of the plate 32. The upper end of the fixed seat 351 is provided with a handle 352. A sliding plate 353 is slidably connected to the inner surface of the fixed seat 351. Slide rods 354 are fixedly connected to both sides of the lower end of the handle 352. The lower ends of the two slide rods 354 pass through the fixed seat 351 and the sliding plate 353 and are fixedly connected to a positioning plate 356. Two springs 355 are connected to the upper end of the sliding plate 353 and the top wall of the inner surface of the fixed seat 351 at the same height. The two springs 355 are both sleeved on the outer surface of a slide rod 354 that is close to each other.

[0037] Specifically, the two positioning plates 356 are all adapted to the shapes of several rectangular holes 342 and two rectangular holes 33.

[0038] In this embodiment, the mudguard assembly 3 can be extended or retracted according to the size of the agricultural tiller. When the length of the mudguard assembly 3 needs to be adjusted, the handle 352 is pulled upward. The handle 352 drives the sliding rod 354 and the positioning plate 356 to move upward until the positioning plate 356 moves out of the corresponding rectangular hole 342, so that the sliding plate 341 can slide freely and the size of the mudguard assembly 3 can be adjusted according to the usage requirements.

[0039] After completion, release the handle 352. Under the push of the spring 355, the sliding plate 353 and the positioning plate 356 will move down, so that the positioning plate 356 moves into the corresponding rectangular hole 342, fixing the position of the sliding plate 341. At the same time, the arc plate 343 can expand the protection range of the mudguard assembly 3.

[0040] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
