Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and in particular to a vibration-type deep soil loosening device. Background Technology

[0002] Deep tillage can effectively break up the hard plow pan formed by long-term plowing or stubble removal, greatly improve the soil's water permeability and aeration, and increase crop yield. Self-excited vibration deep tillage is a low-energy and high-efficiency deep tillage method.

[0003] A search revealed a Chinese patent publication number CN209201464U, which discloses a self-adjusting, self-excited vibration deep tillage device, including a loosening shovel, a plow column, a plow plate, a connecting rod plate, a cam device, a frame, a connecting seat, an excitation device, and a perforated double-headed screw. This patent, through the cam device, can restore some of the self-excited vibration performance of the spring when it loses its excitation performance due to excessive resistance or excessive tillage speed, resulting in more stable operation and higher efficiency.

[0004] However, when the cam rotates, it will collide and rub against the surface of the connecting rod plate. After long-term operation, both the cam and the connecting rod plate will wear down, reducing the service life of the components. Utility Model Content

[0027] Example 1

[0028] A vibration-type deep soil loosening device, such as Figures 1 to 4As shown, the machine includes a frame 1. Two connecting seats 2 are symmetrically installed on the side wall of the frame 1 via bolts. A plow plate 4 is provided on one side of the frame 1. The connecting seat 2 on the upper side of the frame 1 is connected to the plow plate 4 via a vibration assembly 3. The connecting seat 2 on the lower side of the frame 1 is connected to the plow plate 4 via a connecting rod plate 5. One end of the connecting rod plate 5 is hinged to the connecting seat 2, and the other end is fixedly connected to the plow plate 4. A fixing plate 8 is fixed to the outer wall of the frame 1 near the plow plate 4. A cam 9 is rotatably connected to the outer wall of one side of the fixing plate 8. A drive motor for rotating the cam 9 is installed on the other side of the fixing plate 8. A rubber sleeve 10 is provided on the outer wall of the cam 9. A rubber pad 11 is provided on the side wall of the connecting rod plate 5. The rubber sleeve 10 is connected to the cam 9 via the fixing assembly. The fixing assembly includes a limiting groove 12 and a sliding cavity 15. The limiting groove 12 is formed on the side wall of the cam 9, and the rubber sleeve 10 is inserted into the limiting groove 12. The sliding cavity 15 is formed on the side wall of the cam 9, and a fixing rod 16 is slidably connected to the inner wall of the sliding cavity 15. One end of the fixing rod 16 is connected to a limiting spring 17, and the other end of the limiting spring 17 is connected to the inner wall of the sliding cavity 15. A limiting hole is formed on the side wall of the rubber sleeve 10, and one end of the fixing rod 16 is limited to the limiting hole. A limiting block 13 is fixedly connected to the side wall of the rubber pad 11, and a magnetic sheet 14 is fixedly connected to the side wall of the limiting block 13. A positioning groove is formed on the side wall of the connecting rod plate 5, and the limiting block 13 is slidably engaged with the inner wall of the positioning groove. A metal sheet is provided on the inner wall of the positioning groove to magnetically engage with the magnetic sheet 14.

[0029] The bottom end of the plow plate 4 is fixedly connected to the plow column 6, and the other end of the plow column 6 is provided with a deep loosening plate 7. The excitation assembly 3 includes a sliding sleeve 18 and a guide cylinder 19. The sliding sleeve 18 is hinged to one end of the plow plate 4, and one end of the guide cylinder 19 is hinged to the connecting seat 2. The inner wall of the sliding sleeve 18 is slidably engaged with the outer wall of the guide cylinder 19. An excitation spring 20 is sleeved on the outer wall of the sliding sleeve 18. One end of the excitation spring 20 is connected to the sliding sleeve 18, and the other end of the excitation spring 20 is connected to the guide cylinder 19.

[0030] All electrical components in this solution are electrically connected to the controller, and the controller can be a conventional known device such as a computer that provides control.

[0031] During operation, the drive motor rotates the cam 9, propelling the device forward in the working direction. As the tillage resistance changes, the excitation spring 20 reciprocates, and simultaneously, the subsoil plate 7 also reciprocates, thus reducing working resistance. During this process, the cam 9 does not contact the connecting rod plate 5, and the cam 9 idles, resulting in low energy consumption. However, when the working speed is too fast or the soil resistance is too high, the excitation spring 20 is completely compressed, losing its self-excited vibration performance. At this time, the rubber sleeve 10 contacts the rubber pad 11, and under the thrust of the cam 9 on the connecting rod plate 5, the excitation spring 20 recovers some of its self-excited vibration performance. This process repeats until it returns to normal working condition. During the process of the cam 9 pushing the connecting rod plate 5, the rubber sleeve 10 and rubber pad 11... The collision friction replaces the impact friction between the cam 9 and the connecting rod plate 5, improving the service life of the components. When the rubber sleeve 10 and the rubber pad 11 need to be replaced, push the fixing rod 16 upward, the limit spring 17 is compressed and deformed, and the fixing rod 16 is disengaged from the limit hole. At this time, the rubber sleeve 10 can be taken out from the limit groove 12. Then, the new rubber sleeve 10 is inserted into the limit groove 12. Then, the fixing rod 16 is released, the limit spring 17 pushes the fixing rod 16 into the limit hole, and the replacement of the rubber sleeve 10 is completed. Then, the rubber pad 11 is taken off upward, the limit block 13 is disengaged from the positioning groove, and the limit block 13 on one side of the new rubber pad 11 is inserted into the positioning groove. The rubber pad 11 is fixed by the magnetic attraction between the magnetic sheet 14 and the metal sheet.

[0032] By providing a rubber sleeve 10 and a rubber pad 11, during the process of the cam 9 pushing the connecting rod plate 5, the collision friction between the rubber sleeve 10 and the rubber pad 11 replaces the impact friction between the cam 9 and the connecting rod plate 5, thereby improving the service life of the components.

[0033] With the addition of a fixing component, a limiting block 13, and a magnetic sheet 14, the rubber sleeve 10 and rubber pad 11 can be quickly replaced after wear, making the operation convenient.

[0034] Example 2

[0035] A vibration-type deep soil loosening device, this embodiment is based on embodiment 1, with the following improvements, such as... Figure 4 As shown, an installation plate 21 is fixed to the inner wall of the guide cylinder 19. A micro switch 22 is installed on the outer wall of the installation plate 21 near the sliding sleeve 18. A sliding groove is opened on the side wall of the guide cylinder 19. A pressure plate 23 is fixedly connected to the inner wall of the sliding sleeve 18. The pressure plate 23 slides in cooperation with the sliding groove and the inner wall of the guide cylinder 19.

[0036] When the excitation spring 20 reciprocates, the pressure plate 23 moves with the sliding sleeve 18. At this time, the drive motor is in the off state. When the excitation spring 20 is fully compressed and loses its self-excited vibration performance, the pressure plate 23 touches the micro switch 22, and the electrical signal is transmitted to the controller. The controller controls the drive motor to rotate and drives the cam 9 to rotate. When the excitation spring 20 is not fully compressed and loses its self-excited vibration performance, the drive motor will not start, thus reducing energy consumption.

[0037] By incorporating a mounting plate 21, a micro switch 22, and a pressure plate 23, the drive motor will not start when the excitation spring 20 is not fully compressed and loses its self-excited vibration performance, thus reducing energy consumption.

[0038] Working Principle: During operation, the device moves forward along the working direction. As the tillage resistance changes, the excitation spring 20 reciprocates, and simultaneously, the subsoil plate 7 also reciprocates, thereby reducing the working resistance. However, when the working speed is too fast or the soil resistance is too high, the excitation spring 20 is completely compressed and loses its self-excited vibration performance. At this time, the pressure plate 23 touches the micro switch 22, and the electrical signal is transmitted to the controller. The controller controls the drive motor to rotate, driving the cam 9 to rotate. The rubber sleeve 10 contacts the rubber pad 11. Under the pushing force of the cam 9 on the connecting rod plate 5, the excitation spring 20 recovers part of its self-excited vibration performance. This process repeats until it returns to normal working condition. During the process of the cam 9 pushing the connecting rod plate 5, the rubber sleeve 10 and the rubber pad 11... The collision friction of pad 11 replaces the impact friction between cam 9 and connecting rod plate 5, improving the service life of the components. When rubber sleeve 10 and rubber pad 11 need to be replaced, push the fixing rod 16 upward, the limit spring 17 is compressed and deformed, and the fixing rod 16 is disengaged from the limit hole. At this time, the rubber sleeve 10 can be taken out from the limit groove 12. Then, insert the new rubber sleeve 10 into the limit groove 12. Then, release the fixing rod 16, the limit spring 17 pushes the fixing rod 16 into the limit hole, and the replacement of rubber sleeve 10 is completed. Then, the rubber pad 11 is taken off upward, the limit block 13 is disengaged from the positioning groove, and the limit block 13 on one side of the new rubber pad 11 is inserted into the positioning groove. The rubber pad 11 is fixed by the magnetic attraction between the magnetic sheet 14 and the metal sheet.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
