Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery and equipment technology, specifically to an automatic obstacle avoidance elastic mechanism for the tip of a moldboard plow. Background Technology

[0002] The plow body of a moldboard plow mainly consists of a plowshare, plowshare, plow side plates, plowstock, and plow column. During operation, the plowshare first cuts into the soil, creating clods. Then, the clods are broken and turned over along the plowshare, thus covering the surface crop residues and weeds under the furrows. This process achieves soil cutting, breaking, and turning. The moldboard plow can turn and bury crop residues, crushed straw, fertilizer, and even weeds and insect eggs into the cultivated layer. After plowing, the surface is clean, which is conducive to improving the quality of sowing and reducing the occurrence of weeds and pests.

[0003] Currently, when using moldboard plows for tilling, manual operation is mainly relied upon to adjust the working path. When the plow tip accidentally collides with hard obstacles such as stones or tree roots in the field, it is prone to mechanical damage such as deformation and breakage, shortening its service life. At the same time, the violent impact generated by the impact of hard objects will be transmitted back to the traction equipment, causing sudden changes in the load on the power system and affecting the stability of the operation. To address these issues, we propose an automatic obstacle avoidance elastic mechanism for the moldboard plow tip. Utility Model Content

[0006] As a further improvement of this utility model: two blocks are fixedly connected to the inner side of the second sliding connecting shell, and a rubber block is fixedly connected to the output end of the contact sensor.

[0010] As a further improvement of this utility model: two nuts are threaded onto the outer surface of each connecting ring, and two reinforcing plates are fixedly connected to the outer surface of the connecting plate.

[0019] According to one embodiment of the present invention, in conjunction with the appendix Figures 1-4 As shown.

[0020] An automatic obstacle avoidance elastic mechanism for a moldboard plow tip includes a first sliding connecting shell 1, a second sliding connecting shell 2 slidably connected to the inner wall of the first sliding connecting shell 1, a hydraulic push rod 3 fixedly connected to the inner wall of the first sliding connecting shell 1, the output end of the hydraulic push rod 3 connected to the outer surface of the second sliding connecting shell 2, a slider 4 slidably connected to the inner wall of the second sliding connecting shell 2, an elastic element 5 fixedly connected to the outer surface of the slider 4, the outer surface of the elastic element 5 connected to the inner wall of the second sliding connecting shell 2, a moldboard plow body 6 fixedly connected to the bottom surface of the slider 4, a contact sensor 7 fixedly connected to the inner wall of the second sliding connecting shell 2, and a contact sensor 7 fixedly connected to the outer surface of the second sliding connecting shell 2. A Hall sensor 10 is provided. A first magnetic position block 11 is fixedly connected to the inner wall of the first sliding connecting shell 1, and a second magnetic position block 20 is fixedly connected to the inner wall of the first sliding connecting shell 1. By setting an elastic element 5, a buffer can be provided when the moldboard plow body 6 comes into contact with a hard obstacle, reducing the impact of the impact. After the slider 4 contacts the contact sensor 7, the contact sensor 7 will send a signal to control the hydraulic push rod 3 to drive the second sliding connecting shell 2 and the moldboard plow body 6 to avoid the obstacle. When the Hall sensor 10 detects the second magnetic position block 20, it indicates that the obstacle cannot be avoided by the extension and retraction of the hydraulic push rod 3, and then a signal is sent to warn the staff to avoid further damage to the moldboard plow body 6.

[0021] In this embodiment, two blocks 8 are fixedly connected to the inner side of the second sliding connecting shell 2, a rubber block 9 is fixedly connected to the output end of the contact sensor 7, a first reinforcing rib 12 is fixedly connected to the outer surface of the second sliding connecting shell 2, and a second reinforcing rib 13 is fixedly connected to the outer surface of the first sliding connecting shell 1. By setting the blocks 8, the slider 4 can be blocked to avoid damage to the contact sensor 7. By setting the rubber block 9, flexible protection of the contact sensor 7 can be achieved.

[0022] In this embodiment, the outer surface of the slider 4 and the outer surface of the plow body 6 are fixedly connected to a third reinforcing rib 14. An alarm 19 is fixedly connected to the upper surface of the first sliding connecting shell 1. A connecting plate 15 is fixedly connected to the upper surface of the first sliding connecting shell 1. Two connecting rings 16 are slidably connected inside the connecting plate 15. Two nuts 17 are threadedly connected to the outer surface of each connecting ring 16. Two reinforcing plates 18 are fixedly connected to the outer surface of the connecting plate 15. The connection between the device and the frame is achieved by passing the connecting rings 16 through the frame and fixing them with nuts 17.

[0023] Working principle: When using this device, the connecting ring 16 is fitted over the vehicle frame, and the connecting ring 16 is connected and fixed to the vehicle frame by the nut 17. The tractor is started, and the plow tip of the moldboard plow body 6 in this device is moved into the ground to plow. When the plow tip of the moldboard plow body 6 contacts a hard object, the moldboard plow body 6 and the slider 4 will squeeze the elastic element 5. The slider 4 will contact the contact sensor 7, and then the slider 4 will be blocked by the stop block 8, thereby stopping the slider 4 from moving. After the contact sensor 7 contacts the slider 4, it sends a signal to control the hydraulic push rod 3 to extend, thereby driving the second sliding connecting shell 2. The slider 4 and the plow body 6 move, causing the plow body 6 to separate from the hard object. Under the action of the elastic element 5, the slider 4 and the plow body 6 are pushed apart, the signal of the contact sensor 7 is interrupted, and the hydraulic push rod 3 is controlled to retract, so that the second sliding connection shell 2 is reset. After the Hall sensor 10 detects the first magnetic position block 11, it sends a signal to stop the hydraulic push rod 3. During the extension of the hydraulic push rod 3, if the plow body 6 does not separate from the hard object, the Hall sensor 10 will detect the second magnetic position block 20 and send a signal to the alarm 19 to sound an alarm to remind the staff.

[0024] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
