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 tilling land. 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 ploughing depth adjustment device for a plowing machine (authorization announcement number CN106105425B), which includes a support wheel and a joystick, wherein the support wheel is located behind the plowshare, the joystick is rotatably connected to the plowshare, and the joystick is rotatably connected to the support wheel. The support wheel is supported on the ground, and the joystick is pressed or lifted to raise the plowshare, thereby changing the depth of the plowshare in the soil to avoid buried stones.

[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 turns around and continues to turn over the soil after turning over, it will cause the soil to form ditches. Not only is the operational flexibility low, but the process of moving to one side of the starting position also greatly reduces the 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] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] Example 1: Please refer to Figures 1 to 7In an embodiment of the present invention, an adjustable plowshare structure of an agricultural machine includes a body 1, a rotation adjustment component 2 is fixedly connected to the body 1, the rotation adjustment component 2 includes a mounting frame 201, a depth adjustment component 3 is rotatably connected inside the mounting frame 201, and the depth adjustment component 3 includes an adjustment shell 301, and two threaded rotating cylinders 302 are rotatably connected between the upper and lower side walls of the adjustment shell 301, one of the threaded rotating cylinders 302 is fixedly connected to a worm gear 303, and both threaded rotating cylinders 302 are fixedly connected to The gear 304 is connected, and a leather tooth belt 306 is set between the two gears 304. The upper side wall of the adjustment shell 301 is fixedly connected to two limiting square cylinders 305. The two threaded rotating cylinders 302 are threadedly connected with screws 308. The upper end of the screw 308 is fixedly connected with a slider 309, and the slider 309 is slidably connected to the inside of the limiting square cylinder 305. The limiting square cylinder 305 is hinged with a hinge sleeve 307. The lower end of the screw 308 is installed with a soil turning component 4. The sub-control component 5 is fixedly connected to the installation frame 201 The installation frame 201 is provided with a spacing adjustment component 6 inside. When the height of the soil turning component 4 needs to be adjusted, first, the staff starts the electromagnet 509, so that the electromagnet 509 pushes the friction magnetic disk 507 by the magnetic repulsion, so that the friction magnetic disk 507 is close to the friction disk 508, and then starts the motor 208, so that the motor 208 drives the rotating rod 205 to rotate, and the rotating rod 205 drives the worm sleeve 207 to rotate through the sub-control component 5, and the worm sleeve 207 drives the worm wheel 303 to rotate, and the worm wheel 303 is rotated. The wheel 303 drives the threaded rotating drum 302 to rotate, and the threaded rotating drum 302 also drives the gear 304 to rotate. The gear 304 drives another gear 304 to rotate through the leather tooth belt 306, so that the other threaded rotating drum 302 in the adjusting shell 301 rotates synchronously. During the rotation of the threaded rotating drum 302, the slider 309 is limited by the limiting square cylinder 305, so that the threaded rotating drum 302 will drive the screw 308 to move up and down when it rotates, and then the screw 308 drives the soil turning component 4 to move up and down.

[0039] The mounting frame 201 also includes a slide bar 202 fixedly connected to the mounting frame 201, and two slide sleeves 203 are slidably connected to the slide bar 202, and the two slide sleeves 203 are fixedly connected to a cylinder 204, and one end of the cylinder 204 close to the depth adjustment component 3 is fixedly connected to the hinge sleeve 307, and the inner side wall of the mounting frame 201 is rotatably connected to a rotating rod 205, and two rotating sleeves 206 are rotatably connected to the rotating rod 205. The two rotating sleeves 206 are slidably connected to a worm sleeve 207, and the worm sleeve 207 is meshed with the worm wheel 303, and the adjusting shell 301 is rotatably connected to the worm sleeve 207, and a motor 208 is fixedly connected to the side wall of the mounting frame 201, and the output end of the motor 208 is connected to the rotating rod 2 05 fixed connection. When it is necessary to turn the soil, first, by starting one of the cylinders 204, the cylinder 204 pushes the limiting square cylinder 305, so that the limiting square cylinder 305 can rotate downward, so that the turning component 4 can be inserted into the soil. During the movement of the vehicle body 1, the turning component 4 on one side can turn up the soil. After the turning component 4 turns up the soil, the staff does not need to return to the starting position, but only needs to control the two cylinders 204 again to make the turning components 4 on both sides rotate up and down respectively and work alternately. After the positions of the two turning components 4 are exchanged, the staff only needs to turn around and turn the soil again. In this way, the turned soil is not only flat, but also does not require too much movement, and the turning of the soil is more efficient. This product is equipped with a hydraulic lift cylinder 204 on each side, which is used to drive the left The soil turning components 4 on the right side adjust the depth .

[0040] The tilling assembly 4 includes a plowshare 401, to which a plowshare handle 402 is fixedly connected, a locking sleeve 403 is fixedly connected at the lower end of the screw rod 308, and the plowshare handle 402 is plugged into the locking sleeve 403, and the locking sleeve 403 clamps and fixes the plowshare handle 402 through bolts for easy disassembly. In the initial state, the plowshare 401 is set outward. During the tilling process, the plowshare 401 can turn the soil to the outside. When it is necessary to ridge the land, the staff first disassembles and replaces the left and right side tilling assemblies 4 so that the two plowshare assemblies 4 are both set inward. Then the staff starts the two cylinders 204 at the same time, so that the two cylinders 204 extend at the same time, and then pushes the two depth adjustment assemblies 3 to rotate downward at the same time, so that the plowshare assemblies 4 on both sides are inserted into the land. During the movement of the vehicle body 1, the plowshare 4 can turn the soil to the middle, thereby achieving the purpose of ridge the soil.

[0041] Example 2: Please refer to Figures 8 to 9, based on Example 1, the sub-control component 5 includes a fixed box 501 fixedly connected to the installation frame 201, and the two rotating sleeves 206 are both rotatably connected to the fixed box 501, the middle of the rotating rod 205 is rotatably connected to the first pulley 502, and the installation frame 201 is internally rotatably connected to the screw rod 503, the threads on the screw rod 503 are symmetrically arranged, the middle of the screw rod 503 is fixedly connected to the second pulley 504, a belt 505 is sleeved between the first pulley 502 and the second pulley 504, the middle of the rotating rod 205 is fixedly connected to the limit strip 506, and the limit strip 506 is located inside the fixed box 501, the opposite ends of the two rotating sleeves 206 are fixedly connected to the left and right side walls of the first pulley 502, and the left and right sides of the first pulley 502 are provided with friction magnetic discs 507, the surfaces of the friction magnetic discs 507 and the friction discs 508 are both rough-polished, and the friction magnetic discs 5 07 is slidably connected to the limit bar 506. When the friction magnetic disk 507 fits with the friction disk 508 under the action of magnetic force, the friction magnetic disk 507 can drive the friction disk 508 to rotate through the friction force when it rotates. The inner walls on the left and right sides of the fixed box 501 are fixedly connected with electromagnets 509, and the electromagnets 509 are magnetically connected to the friction magnetic disk 507. When it is necessary to adjust the height of the soil turning component 4, it is necessary to start the electromagnet 509 so that the electromagnet 509 can rely on the magnetic force to absorb the friction magnetic disk 507, so that the friction magnetic disk 507 fits with the friction disk 508 under the action of magnetic force. When the rotating rod 205 rotates, the friction magnetic disk 507 is driven to rotate through the limit bar 506, and the friction magnetic disk 507 drives the friction disk 508 to rotate. The friction disk 508 drives the rotating sleeve 206 to rotate. Finally, the rotation of the depth adjustment component 3 is realized by rotating the adjustment component 2 and the depth adjustment component 3.

[0042] It is worth noting that when the depth adjustment component 3 rotates upward, the adjustment shell 301 rotates around the worm sleeve 207, allowing the worm wheel 303 to rotate around the worm sleeve 207. During this process, the worm wheel 303 may rotate slightly, but this will not affect the rotation of the depth adjustment component 3.

[0043] The interval adjustment component 6 includes two threaded moving cylinders 601, and the two threaded moving cylinders 601 are threadedly connected to the screw rod 503, and the two threaded moving cylinders 601 are rotatably connected with a moving plate 602, and the moving plate 602 is rotatably connected to the sliding sleeve 203 and the worm sleeve 207 respectively. 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 to push the friction magnetic disk 507 to move, so that the friction magnetic disk 507 approaches the first pulley 502 and is tightly attached to the friction disk 508 fixed on the first pulley 502. At this time, the motor 208 drives the rotating rod 205 to rotate, and 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 the friction force. The rubbing plate 508 drives the first pulley 502 to rotate, and the first pulley 502 drives the second pulley 504 to rotate through the belt 505, and the second pulley 504 drives the screw rod 503 to rotate, so that the screw rod 503 can drive the two threaded moving cylinders 601 to move at the same time, and then when the threaded moving cylinder 601 moves, the sliding sleeve 203 and the worm sleeve 207 can be driven to move at the same time through the moving plate 602, thereby driving the synchronous movement of the depth adjustment component 3 and the sliding sleeve 203 and the cylinder 204 to achieve the adjustment of the interval between the two depth adjustment components 3. It is worth noting 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 it rotates.

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

[0045] When the present invention needs to turn the soil, first start one of the cylinders 204, and the cylinder 204 pushes the limiting square cylinder 305, so that the limiting square cylinder 305 can rotate downward, so that the soil turning component 4 on one side can be inserted into the soil. During the movement of the vehicle body 1, the vehicle body 1 drives the soil turning component 4 to turn the soil to the outside through the depth adjustment component 3. The staff only needs to control the two cylinders 204 again to make the soil turning components 4 on both sides rotate up and down respectively and face downward alternately. 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, so that the turned soil is not only flat, but also does not require excessive movement, and the soil turning is more efficient.

[0046] When the depth of soil turning needs to be adjusted, the electromagnet 509 needs to be started first, so that the electromagnet 509 can rely on magnetic force to absorb the friction magnetic disk 507, so that the friction magnetic disk 507 fits with the friction disk 508 under the action of magnetic force, and then the motor 208 is started, so that the motor 208 drives the rotating rod 205 to rotate. When the rotating rod 205 rotates, the friction magnetic disk 507 is driven to rotate through the limit bar 506, and the friction magnetic disk 507 drives the friction disk 508 to rotate. The friction disk 508 drives the rotating sleeve 206 to rotate, and 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. The gear 304 drives another gear 304 to rotate through the leather tooth belt 306, so that another threaded rotating cylinder 302 in the adjusting shell 301 rotates synchronously. During the rotation of the threaded rotating cylinder 302, the limit square cylinder 305 limits the slider 309, so that the threaded rotating cylinder 302 rotates and drives the screw 308 to move up and down, and then the screw 308 drives the soil turning component 4 to move up and down;

[0047] In addition, the device can also be used to ridge the land. When ridges need to be ridged, the staff first disassembles and replaces the soil turning components 4 on the left and right sides, so that the two soil turning components 4 are both set inward, and then the staff simultaneously starts the two cylinders 204, so that the two cylinders 204 extend at the same time, and then push 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, so as to achieve the purpose of soil ridges;

[0048] When the spacing of the soil turning assembly 4 needs to be adjusted, first, the staff needs to change the polarity of the electromagnet 509 so that the electromagnet 509 generates 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 to be in close contact with the friction disk 508 fixed on the first pulley 502. At this time, the motor 208 drives the rotating rod 205 to rotate, and 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 the friction force, and the friction disk 507 drives the friction disk 508 to rotate. 08 drives the first pulley 502 to rotate, and the first pulley 502 in turn drives the second pulley 504 to rotate through the belt 505, and the second pulley 504 drives the screw rod 503 to rotate, so that the screw rod 503 can simultaneously drive the two threaded moving cylinders 601 to move, and then when the threaded moving cylinder 601 moves, the sliding sleeve 203 and the worm sleeve 207 can be driven to move at the same time through the moving plate 602, thereby driving the synchronous movement of the depth adjustment component 3 and the sliding sleeve 203 and the cylinder 204, so as to realize the adjustment of the interval between the two depth adjustment components 3.

[0049] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
