Description

Technical Field

[0001] The invention relates to the technical field of agricultural machinery and equipment, in particular to an adjustable plowshare structure of an agricultural machine. Background Art

[0002] A plowshare is a type of agricultural tool, mainly used for plowing. Its structure usually consists of a plowshare, a plow body and a plow handle. The plowshare is usually sharp and can effectively cut into the soil, while the plow body is responsible for turning over and breaking the soil. The working principle of the plowshare is to use the traction of the plow to turn the soil over, making it loose and suitable for sowing and growing crops. In agricultural production, the use of a plowshare can improve soil structure, promote the absorption of water and nutrients, and thus increase crop yields.

[0003] A Chinese patent discloses a plowing depth adjustment device for a plowing machine (authorization publication number CN106105425B). The device includes a support wheel and a joystick. The support wheel is located behind the plowshare, and the joystick is rotatably connected to the plowshare. The joystick is also rotatably connected to the support wheel. With the support wheel supported on the ground, pressing or lifting the joystick raises the plowshare, changing its depth in the soil to avoid buried rocks.

[0004] However, in the process of tilling the land with the plowshare, the above patent and most of the existing plowshares turn the soil to one side. In order to make the soil have a certain flatness after turning over, the plowshare needs to be moved to one side of the starting position before turning over the soil. If the plowshare is turned around and continued to turn over the soil after turning over, it will cause ditches to form in the soil. Not only is the operational flexibility low, but the process of moving to one side of the starting position also greatly reduces work efficiency. In addition, the existing plowshare has a single function, and the distance and depth between the two existing plowshares cannot be conveniently adjusted. Summary of the Invention

[0037] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0038] Embodiment 1: Please refer to Figures 1 to 7, in the embodiment of the present invention, an adjustable plowshare structure of an agricultural machine includes a vehicle body 1. A rotary adjustment component 2 is fixedly connected to the vehicle body 1. The rotary adjustment component 2 includes a mounting frame 201. A depth adjustment component 3 is rotatably connected inside the mounting frame 201. The depth adjustment component 3 includes an adjustment shell 301. Two threaded drums 302 are rotatably connected between the upper and lower side walls of the adjustment shell 301. A worm gear 303 is fixedly connected to one of the threaded drums 302. Gears 304 are fixedly connected to both of the threaded drums 302. A toothed belt 306 is sleeved between the two gears 304. Two limit square tubes 305 are fixedly connected to the upper side wall of the adjustment shell 301. Screws 308 are threadedly connected to both of the threaded drums 302. The upper end of the screw 308 is fixedly connected to a slider 309, and the slider 309 is slidably connected inside the limit square tube 305. A hinge sleeve 307 is hinged to the limit square tube 305. A soil-turning component 4 is installed at the lower end of the screw 308. A sub-control component 5 is fixedly connected to the mounting frame 201. An interval adjustment component 6 is arranged inside the mounting frame 201. When it is necessary to adjust the height of the soil-turning component 4, first, the staff activates the electromagnet 509, and the electromagnet 509 relies on the repulsive force of magnetism to push the friction magnetic disc 507, so that the friction magnetic disc 507 is closely attached to the friction disc 508. Then, the motor 208 is started, and the motor 208 drives the rotating rod 205 to rotate. The rotating rod 205 drives the worm gear sleeve 207 to rotate through the sub-control component 5. The worm gear sleeve 207 drives the worm gear 303 to rotate. The worm gear 303 drives the threaded drum 302 to rotate. The threaded drum 302 also drives the gear 304 to rotate at the same time. The gear 304 drives another gear 304 to rotate through the toothed belt 306, so that the other threaded drum 302 in the adjustment shell 301 rotates synchronously. During the rotation of the threaded drum 302, due to the limitation of the slider 309 by the limit square tube 305, when the threaded drum 302 rotates, it will drive the screw 308 to move up and down, and further drive the soil-turning component 4 to move up and down.

[0039] The mounting frame 201 further includes a slide bar 202 fixedly connected to the mounting frame 201. Two sliding sleeves 203 are slidably connected to the slide bar 202. Air cylinders 204 are fixedly connected to both of the two sliding sleeves 203. One end of the air cylinder 204 close to the depth adjustment component 3 is fixedly connected to the hinge sleeve 307. A rotating rod 205 is rotatably connected to the inner side wall of the mounting frame 201. Two rotating sleeves 206 are rotatably connected to the rotating rod 205. Two worm gear sleeves 207 are slidably connected to both of the two rotating sleeves 206, and the worm gear sleeve 207 meshes with the worm wheel 303. The adjustment housing 301 is rotatably connected to the worm gear sleeve 207. A motor 208 is fixedly connected to the side wall of the mounting frame 201, and the output end of the motor 208 is fixedly connected to the rotating rod 205. When soil turning is required, first, by starting one of the air cylinders 204, the air cylinder 204 pushes the limit square tube 305, enabling the limit square tube 305 to rotate downward, so that the soil turning component 4 can be inserted into the soil. During the movement of the vehicle body 1, the soil turning component 4 on one side can turn up the soil. After the soil turning component 4 turns up the soil, the staff does not need to return to the starting position. They only need to control the two air cylinders 204 again to make the two soil turning components 4 rotate up and down respectively and work alternately. After the positions of the two soil turning components 4 are exchanged, the staff only need to turn around and turn the soil again. In this way, the turned soil is not only flat, but also does not need to be moved too much, and the soil turning is more efficient. , this product is equipped with a hydraulic lift with a cylinder 204 on each of the left and right sides, respectively used to drive the soil-turning components 4 on the left and right sides to adjust the depth 。

[0040] The soil turning component 4 includes a plowshare 401. A plow handle 402 is fixedly connected to the plowshare 401. The lower end of the screw 308 is fixedly connected to a locking sleeve 403, and the plow handle 402 is inserted into the locking sleeve 403. The locking sleeve 403 clamps and fixes the plow handle 402 through bolts for easy disassembly. In the initial state, the plowshare 401 faces outward. During soil turning, the plowshare 401 can turn the soil to the outside. When ridging the land is required, the staff first disassemble and replace the soil turning components 4 on the left and right sides to make both of the two soil turning components 4 face inward. Then the staff start the two air cylinders 204 at the same time, making the two air cylinders 204 extend at the same time, and then pushing the two depth adjustment components 3 to rotate downward at the same time, so that the soil turning components 4 on both sides are inserted into the land. During the movement of the vehicle body 1, the soil turning components 4 can turn the soil to the middle to achieve the purpose of soil ridging.

[0041] Embodiment 2: Please refer to Figures 8 to 9, on the basis of Embodiment 1, the sub-control component 5 includes a fixed box 501 fixedly connected to the installation frame 201, and both rotating sleeves 206 are rotatably connected to the fixed box 501. The middle of the rotating rod 205 is rotatably connected to a first pulley 502. A screw rod 503 is rotatably connected inside the installation frame 201. The threads on the screw rod 503 are symmetrically arranged. The middle of the screw rod 503 is fixedly connected to a second pulley 504. A belt 505 is sleeved between the first pulley 502 and the second pulley 504. A limiting strip 506 is fixedly connected to the middle of the rotating rod 205, and the limiting strip 506 is located inside the fixed box 501. Friction disks 508 are fixedly connected to the left and right side walls of the first pulley 502 at the relative ends of the two rotating sleeves 206. Friction magnetic disks 507 are arranged on both the left and right sides of the first pulley 502. The surfaces of the friction magnetic disks 507 and the friction disks 508 are both treated by rough grinding, and the friction magnetic disks 507 are slidably connected to the limiting strip 506. When the friction magnetic disks 507 are fitted to the friction disks 508 under the action of magnetic force, when the friction magnetic disks 507 rotate, they can drive the friction disks 508 to rotate through friction. Electromagnets 509 are fixedly connected to the left and right inner walls of the fixed box 501, and the electromagnets 509 are magnetically connected to the friction magnetic disks 507. When it is necessary to adjust the height of the soil-turning component 4, it is necessary to start the electromagnets 509 so that the electromagnets 509 can adsorb the friction magnetic disks 507 by magnetic force, so that the friction magnetic disks 507 are fitted to the friction disks 508 under the action of magnetic force. When the rotating rod 205 rotates, it drives the friction magnetic disks 507 to rotate through the limiting strip 506. The friction magnetic disks 507 drive the friction disks 508 to rotate. The friction disks 508 drive the rotating sleeves 206 to rotate. Finally, through the rotation adjustment component 2 and the depth adjustment component 3, the rotation of the depth adjustment component 3 is realized.

[0042] It should be noted that when the depth adjustment component 3 rotates upward, the adjustment shell 301 will rotate around the worm sleeve 207, so that the worm wheel 303 can rotate around the worm sleeve 207. In this process, the worm wheel 303 may rotate slightly, but this will not affect the rotation of the depth adjustment component 3.

[0043] The spacing adjustment component 6 includes two threaded moving cylinders 601, and the two threaded moving cylinders 601 are threadedly connected to the screw rod 503. Rotating plates 602 are rotatably connected to both of the two threaded moving cylinders 601, and the rotating plates 602 are respectively rotatably connected to the sliding sleeve 203 and the worm sleeve 207. When it is necessary to adjust the spacing of the soil-turning component 4, first, the staff needs to change the polarity of the electromagnet 509 to make the electromagnet 509 generate a magnetic repulsive force, which pushes the friction magnetic disk 507 to move, causing the friction magnetic disk 507 to approach the first pulley 502 and press against the friction disk 508 fixed on the first pulley 502. At this time, the motor 208 is used to drive the rotating rod 205 to rotate. The rotating rod 205 drives the friction magnetic disk 507 to rotate, so that the friction magnetic disk 507 drives the friction disk 508 to rotate through friction. The friction disk 508 drives the first pulley 502 to rotate, and the first pulley 502 drives the second pulley 504 to rotate through the belt 505. The second pulley 504 drives the screw rod 503 to rotate, enabling the screw rod 503 to drive the two threaded moving cylinders 601 to move simultaneously. Furthermore, when the threaded moving cylinders 601 move, the sliding sleeve 203 and the worm sleeve 207 can be simultaneously driven to move through the rotating plates 602, thereby driving the synchronous movement of the depth adjustment component 3, the sliding sleeve 203, and the cylinder 204, and realizing the adjustment of the spacing between the two depth adjustment components 3. It should be noted that when the friction magnetic disk 507 is not in contact with the friction disk 508 fixed on the first pulley 502, since the first pulley 502 is rotatably connected to the rotating rod 205, the rotating rod 205 will not drive the first pulley 502 to rotate when rotating.

[0044] The working principle of the present invention is as follows:

[0045] When the present invention needs to turn the soil, first, one of the cylinders 204 is started. The cylinder 204 pushes the limiting square tube 305, enabling the limiting square tube 305 to rotate downward, so that one side of the soil-turning component 4 can be inserted into the soil. During the movement of the vehicle body 1, the vehicle body 1 drives the soil-turning component 4 through the depth adjustment component 3 to turn the soil to the outside. The staff only needs to control the two cylinders 204 again to respectively rotate and adjust the two soil-turning components 4 up and down, alternately downward. After the positions of the two soil-turning components 4 are exchanged, the staff only needs to turn around and turn the soil again. In this way, the turned soil can all face one direction, making the turned soil not only flat but also without excessive movement, and the soil-turning is more efficient.

[0046] When it is necessary to adjust the depth of soil turning, first, the electromagnet 509 needs to be activated so that the electromagnet 509 can adsorb the friction magnetic disk 507 by magnetic force, making the friction magnetic disk 507 fit with the friction disk 508 under the action of magnetic force. Then, the motor 208 is activated to drive the rotating rod 205 to rotate. When the rotating rod 205 rotates, it drives the friction magnetic disk 507 to rotate through the limiting strip 506. The friction magnetic disk 507 drives the friction disk 508 to rotate, the friction disk 508 drives the rotating sleeve 206 to rotate, the rotating sleeve 206 drives the worm sleeve 207 to rotate, the worm sleeve 207 drives the worm wheel 303 to rotate, and the worm wheel 303 drives the threaded rotating cylinder 302 to rotate. The threaded rotating cylinder 302 also drives the gear 304 to rotate at the same time. The gear 304 drives another gear 304 to rotate through the leather tooth belt 306, making the other threaded rotating cylinder 302 in the adjusting shell 301 rotate synchronously. During the rotation of the threaded rotating cylinder 302, due to the limitation of the limiting square cylinder 305 on the slider 309, when the threaded rotating cylinder 302 rotates, it will drive the screw rod 308 to move up and down, and further drive the soil turning component 4 to move up and down;

[0047] In addition, this device can also be used for ridging the land. When ridging is required, the staff first disassemble and replace the soil turning components 4 on both the left and right sides, making both soil turning components 4 face inward. Subsequently, the staff simultaneously activate the two cylinders 204, causing the two cylinders 204 to extend simultaneously, and then pushing the two depth adjusting components 3 to rotate downward simultaneously, so that the soil turning components 4 on both sides are inserted into the land. During the movement of the vehicle body 1, the soil turning components 4 can turn the soil to the middle, achieving the purpose of soil ridging;

[0048] When it is necessary to adjust the spacing of the soil turning components 4, first, the staff needs to change the polarity of the electromagnet 509 to make the electromagnet 509 generate magnetic repulsive force, pushing the friction magnetic disk 507 to move, prompting the friction magnetic disk 507 to approach the first pulley 502 and stick tightly to the friction disk 508 fixed on the first pulley 502. At this time, the motor 208 is used to drive the rotating rod 205 to rotate again. The rotating rod 205 drives the friction magnetic disk 507 to rotate, and the friction magnetic disk 507 drives the friction disk 508 to rotate through friction. The friction disk 508 drives the first pulley 502 to rotate, and the first pulley 502 drives the second pulley 504 to rotate through the belt 505. The second pulley 504 drives the screw rod 503 to rotate, enabling the screw rod 503 to drive the two threaded moving cylinders 601 to move simultaneously. Then, when the threaded moving cylinders 601 move, the moving plate 602 can drive the sliding sleeve 203 and the worm sleeve 207 to move simultaneously, and further drive the synchronous movement of the depth adjusting components 3, the sliding sleeve 203, and the cylinders 204, realizing the adjustment of the interval between the two depth adjusting components 3.

[0049] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes, shall be covered by the protection scope of the present invention.
