Description

Technical Field

[0001] This utility model relates to an agricultural ditching device, belonging to the field of agricultural machinery technology. Background Technology

[0002] Ditching in farmland offers numerous benefits, including improving soil moisture, enhancing soil fertility, promoting crop growth, and reducing fertilizer waste. By creating ditches in farmland, soil moisture can be effectively regulated, increasing the soil's water retention capacity, thereby reducing soil erosion and improving water utilization. Furthermore, ditching helps fertilizers reach the crop roots more effectively, improving fertilizer absorption efficiency, reducing fertilizer waste, and enabling fruit trees to maximize the conversion and absorption of fertilizers, thus promoting healthy crop growth.

[0003] An existing patent publication number, CN221710428U, describes an agricultural ditching device. This device allows for adjustment of the ditch width, making it suitable for a wider range of crops. It also incorporates a soil-loosening component to loosen the soil in front during ditching, improving efficiency. However, as seen in the drawing, this device is driven by a pull-and-push mechanism, lacking a stable support structure on its outer side. This makes it difficult to ensure uniformity during ditching, leading to uneven surfaces and hindering precise control of ditch depth, thus affecting the ditching effect. Furthermore, while the device can adjust the ditch width by rotating the horizontal plate, the vertical plate compresses the loosened soil into a vertical surface, causing soil collapse and affecting the stability of the ridges. The device also presents significant resistance during lateral pushing, increasing the workload for workers. Utility Model Content

[0004] The purpose of this invention is to provide an agricultural ditching device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An agricultural ditching device includes a support frame, a loosening wheel, and a ditching plow. Support rollers are rotatably connected to the lower ends of the front and rear sides of the support frame. A first screw is rotatably connected to the middle position of the lower end of the upper wall of the support frame. A lifting sleeve is spirally connected to the outer side of the first screw. A lifting support plate is fixedly connected to the lower end of the lifting sleeve. A loosening wheel is rotatably connected to the lower right side of the lifting support plate. A ditching plow is fixedly connected to the middle position of the lower end of the lifting support plate. Inclined push plates are rotatably connected to the front and rear sides of the left end of the ditching plow.

[0007] Furthermore, a handle is fixedly connected to the upper left side of the support frame, and a traction ring is fixedly connected to the right end of the support frame.

[0008] Furthermore, a stepper motor is fixedly connected at the middle position of the upper end of the support frame, and the output shaft of the stepper motor is fixedly connected to the first screw.

[0009] Furthermore, a limiting telescopic rod is fixedly connected to the upper corner of the lifting support plate, and the limiting telescopic rod is fixedly connected to the support frame.

[0010] Furthermore, a control motor is fixedly connected to the right front side of the lifting support plate, and a sprocket assembly is fixedly connected to the front end of the output shaft of the control motor. The sprocket assembly is rotatably connected to the lifting support plate, and the lower sprocket of the sprocket assembly is fixedly connected to the loosening wheel.

[0011] Furthermore, a fixed sleeve is fixedly connected to the upper left end of the furrowing plow, and a second screw is screwed to the inner side of the fixed sleeve. A transmission block is rotatably connected to the outer left end of the second screw, and transmission rods are rotatably connected to both the front and rear sides of the transmission block. The transmission rods are rotatably connected to the inclined push plate.

[0012] Furthermore, a turntable is rotatably connected to the left end of the transmission block, and the turntable is fixedly connected to the second screw. A pull handle is provided on the upper left side of the turntable, and a limit rod is fixedly connected to the right end of the pull handle. The limit rod is slidably connected to the turntable, and a limit frame is slidably connected to the right end of the limit rod. The limit frame is fixedly connected to the transmission block, and a spring is covered on the surface of the left side of the limit rod.

[0013] The beneficial effects of this utility model are:

[0014] This invention utilizes supporting rollers to provide overall support for the device's movement. Pushing the handle and pulling the traction ring enables rapid movement. The rotation of the stepper motor rotates the first screw, and the limiting telescopic rod allows the lifting sleeve to move up and down, thereby moving the loosening wheel and ditching structure vertically. This allows for precise control of the ditching depth, improving the ditching effect in farmland. The invention also utilizes a control motor to rotate the sprocket assembly, which in turn drives the loosening wheel. The ditching plow then performs initial ditching on the loosened soil. The tilting pusher can tilt and push loose soil to both sides, making the sides of the trench inclined, so that the cross-section of the ridge forms a stable trapezoidal structure. By pulling the handle, the limiting rod can move to the left and the turntable can rotate, which in turn can drive the transmission block to move left and right, so that the transmission rod can drive the tilting pusher on the front and rear sides to rotate, thereby adjusting the trench width. After adjusting and releasing the pull handle, the spring can extend, so that the limiting rod can be re-inserted into the limiting frame, preventing the second screw from loosening during the movement of the device and improving the stability of the tilting pusher after adjustment.

Support rollers 2 are rotatably connected to the lower ends of the front and rear sides of the support frame 1. A first screw 3 is rotatably connected to the middle position of the lower end of the upper wall of the support frame 1. A lifting sleeve 4 is spirally connected to the outer side of the first screw 3. A lifting support plate 5 is fixedly connected to the lower end of the lifting sleeve 4. A handle 9 is fixedly connected to the left side of the upper end of the support frame 1. A traction ring 10 is fixedly connected to the right end of the support frame 1. A stepper motor 11 is fixedly connected to the middle position of the upper end of the support frame 1. The output shaft of the stepper motor 11 is fixedly connected to the first screw 3. The upper end of the lifting support plate 5... A limiting telescopic rod 12 is fixedly connected at the corner position. The limiting telescopic rod 12 is fixedly connected to the support frame 1. The support roller 2 is set to support the overall movement of the device. The device can move quickly by pushing the handle 9 and pulling the traction ring 10. The first screw 3 can be rotated by rotating the stepper motor 11. Under the limiting action of the limiting telescopic rod 12, the lifting sleeve 4 can drive the lifting support plate 5 to move up and down. In turn, the loosening wheel 6 and the ditching structure can move up and down, so as to accurately control the ditching depth and improve the ditching effect of farmland.

[0024] Please refer to Example 2 Figure 1 , Figure 3 and Figure 4The difference between this embodiment and Embodiment 1 is as follows: a loosening wheel 6 is rotatably connected to the lower right side of the lifting support plate 5; a furrowing plow 7 is fixedly connected to the middle position of the lower end of the lifting support plate 5; inclined push plates 8 are rotatably connected to both the front and rear sides of the left end of the furrowing plow 7; a control motor 13 is fixedly connected to the right front side of the lifting support plate 5; a sprocket assembly 14 is fixedly connected to the front end of the output shaft of the control motor 13; the sprocket assembly 14 is rotatably connected to the lifting support plate 5; the lower sprocket of the sprocket assembly 14 is fixedly connected to the loosening wheel 6; and the upper left side of the furrowing plow 7 is fixedly connected to... A fixed sleeve 15 is provided, with a second screw 16 screwed to the inner side of the fixed sleeve 15. A transmission block 17 is rotatably connected to the outer left end of the second screw 16. Transmission rods 18 are rotatably connected to both the front and rear sides of the transmission block 17. The transmission rods 18 are rotatably connected to the inclined push plate 8. A turntable 19 is rotatably connected to the left end of the transmission block 17. The turntable 19 is fixedly connected to the second screw 16. A pull handle 20 is provided on the upper left side of the turntable 19. A limit rod 21 is fixedly connected to the right end of the pull handle 20. The limit rod 21 slides between the turntable 19 and the limit rod 21. The right end of the limiting rod 21 is slidably connected to the limiting frame 22, which is fixedly connected to the transmission block 17. The left side of the limiting rod 21 is covered with a spring 23. The rotation of the control motor 13 causes the sprocket assembly 14 to drive the loosening wheel 6 to rotate. The furrowing plow 7 can perform preliminary furrowing on the loose soil. The inclined pusher 8 can push the loose soil to both sides, making the sides of the furrow inclined, so that the cross-section of the ridge forms a stable trapezoidal structure. The pulling handle can also be used to further facilitate the furrowing process. Pulling the handle 20 allows the limiting rod 21 to move to the left and the turntable 19 to rotate. This causes the second screw 16 to drive the transmission block 17 to move left and right, so that the transmission rod 18 can drive the inclined push plates 8 on the front and rear sides to rotate. This allows for adjustment of the groove width. After adjusting and releasing the handle 20, the spring 23 extends, allowing the limiting rod 21 to re-insert into the limiting frame 22. This prevents the second screw 16 from loosening during device movement and improves the stability of the inclined push plate 8 after adjustment.

[0025] The working principle of this utility model is as follows: During use, the supporting rollers 2 provide overall support for the device's movement. Pushing the handle 9 and pulling the traction ring 10 allows for rapid movement. The stepper motor 11 rotates the first screw 3, and under the limiting action of the telescopic rod 12, the lifting sleeve 4 drives the lifting support plate 5 to move up and down. This, in turn, allows the loosening wheel 6 and the ditching structure to move up and down, facilitating precise control of the ditching depth and improving the ditching effect in farmland. The control motor 13 rotates the sprocket assembly 14, which in turn drives the loosening wheel 6. The ditching plow 7 then performs preliminary ditching on the loosened soil. The inclined push plate 8 can push the loose soil to both sides, making the sides of the trench inclined, so that the cross-section of the ridge forms a stable trapezoidal structure. By pulling the handle 20, the limiting rod 21 can move to the left and the turntable 19 can rotate. This allows the second screw 16 to drive the transmission block 17 to move left and right, so that the transmission rod 18 can drive the inclined push plates 8 on the front and rear sides to rotate. This allows for adjustment of the trench width. After adjusting and releasing the handle 20, the spring 23 can extend, allowing the limiting rod 21 to re-insert into the limiting frame 22. This prevents the second screw 16 from loosening during the movement of the device and improves the stability of the inclined push plate 8 after adjustment.
