Description

Technical Field

[0001] The present invention belongs to the technical field of land consolidation, and particularly relates to a land consolidation device for ecological restoration. Background Art

[0002] During the process of ecological restoration, it is often necessary to carry out land consolidation to improve the production and operation conditions of the agricultural and forestry economy, and to promote soil improvement and land development. Land consolidation refers to the comprehensive improvement of fields, water, roads, forests, and villages through various measures to improve the quality of cultivated land and increase the effective cultivated land area. In this process, the land needs to be leveled and the soil layer needs to be loosened, so land consolidation devices such as rotary tillers are used to participate in the work. However, in the rotary tillage process of traditional land consolidation devices, since there are stones mixed in the soil and it is not easy to select the stones during the rotary tillage process, it is easy to affect the normal growth rate of crops during the subsequent crop planting process. Moreover, although traditional land consolidation devices can break up hard soil layers, there will still be a large number of large-volume soil blocks after breaking up the hard soil layers, thus reducing the soil fragmentation effect.

[0003] After retrieval, the Chinese patent with the application number 2023110308959 discloses a land consolidation device for ecological restoration, including: a machine shell; a rotary tillage cutter is installed on the front side inside the machine shell, and a gearbox is installed in the middle of the front side of the upper end surface of the machine shell, and there is a transmission box between the gearbox and the cutter shaft of the rotary tillage cutter; a support mechanism is provided on each of the left and right side surfaces of the machine shell, and a feeding component is provided on the top end surface inside the machine shell; a soil fragmentation mechanism is installed on the rear end surface of the machine shell, and a locking part is provided on the rear side of the top end surface of the machine shell; through the cooperation of the rotary tillage cutter, the screening mesh plate and the feeding component, the present invention can select stones during the rotary tillage process to avoid affecting the normal growth rate of crops; it solves the problem that in the rotary tillage process of traditional land consolidation devices, since there are stones mixed in the soil and it is not easy to select the stones during the rotary tillage process, it is easy to affect the normal growth rate of crops during the subsequent crop planting process, but there are still the following defects: during the clockwise rotation of the rotary tillage cutter, the stones in the soil are thrown onto the screening mesh plate on the rear side inside the machine shell, and then the soil passes through the mesh holes of the screening mesh plate and falls onto the land. However, large soil blocks and stones will be intercepted by the screening mesh plate, and the separation of large soil blocks and stones cannot be achieved, thus reducing the screening effect of the screening mesh plate.

The movable frame has two guide rails which are respectively provided at two ends of the movable frame and a guide rail which are provided at the bottom of the movable frame to move relative to the movable frame.

[0011] Preferably, guide rods are slidably installed on the upper and lower sides of the four side walls of the frame, and a movable plate is provided on one side of the four side walls inside the frame. The movable plate is a rubber plate, and two symmetrical movable plates are slidably connected to the cross bar. One end of the guide rod is connected to the movable plate, and a limiting plate is installed on the other end. Springs are installed around the guide rod, between the movable plate and the side wall of the frame.

[0012] Preferably, the cross section of the cross bar is triangular.

[0013] Preferably, a receiving plate is provided on one side of the frame and below the conveying mechanism. The receiving plate is obliquely installed inside the base, and the lower part of the receiving plate is connected to the screening mechanism.

[0014] Preferably, a plurality of protrusions are provided on the circumferential surface of the cam.

[0015] Preferably, a baffle is provided on the periphery of the chain, and the baffle is installed inside the base.

[0016] Preferably, guide blocks are installed on both sides of the support frame, and guide grooves matching with the guide blocks are opened on the inner side wall of the base, and the support frame is slidably installed in the guide grooves on the base through the guide blocks.

[0017] The beneficial effects of the present invention are as follows: 1) The large soil clods can be broken up by the breaking-up mechanism, and the small soil clods and stones after breaking-up are screened by the screening mechanism, so that the small soil clods and stones are separated, improving the overall screening effect.

[0018] 2) The telescopic rod drives the support frame to move downward by a certain distance. At this time, the first motor works to drive the first rotating shaft to rotate, and the worm on the first rotating shaft rotates accordingly. The worm meshes with the worm wheel to drive the rotary tillage shaft to rotate, and the rotary tillage cutters on the rotary tillage shaft rotate accordingly. Then, the telescopic rod drives the support frame to move downward to the required depth again. The rotary tillage cutters on the rotary tillage shaft contact the land for loosening the soil, and the soil and stones acted on by the rotary tillage cutters are then thrown backward onto the conveying mechanism.

[0019] 3) Guide blocks are installed on both sides of the support frame. Guide grooves matching with the guide blocks are opened on the inner side wall of the base body. The support frame is slidably installed in the guide grooves on the base body through the guide blocks, so that the support frame can always contact the base body through the guide blocks when moving up and down, improving the stability of the support frame during movement.

[0020] 4) The second motor works to drive the connecting shaft to rotate. The two first sprockets on the connecting shaft rotate synchronously. The first sprocket meshes with the chain to drive the chain to move, and then drives the second sprocket to rotate. While the chain is moving, the support rods on the chain move synchronously. The soil and stones thrown during the operation of the rotary tillage mechanism fall onto the support rods. The fine soil and stones can pass through the support rods and fall on the ground, while the larger stones and soil clods cannot fall and move with the support rods and finally fall into the breaking-up mechanism. Since there is vibration when the chain is moving, the vibration can be transmitted to the support rods, and the loose soil clods can be shaken loose by the support rods. The shaken soil clods can pass through the support rods and fall on the ground, improving the working efficiency of land preparation.

[0021] 5) A baffle is provided on the periphery of the chain. The baffle is installed inside the base body. The baffle can prevent soil clods and stones from falling on the chain, causing damage and pollution to the chain. Under the action of the baffle, direct contact between the chain and the soil clods and stones can be avoided, prolonging the service life of the chain and reducing the production cost.

[0022] 6) The second motor operates to drive the connecting shaft to rotate. The first pulley located on the connecting shaft rotates accordingly. The first pulley drives the second pulley to rotate through the first belt. The third rotating shaft connected to the second pulley rotates synchronously. The second bevel gear located on the third rotating shaft rotates accordingly. The second bevel gear meshes with the first bevel gear to drive the second rotating shaft to rotate. The roller located on the second rotating shaft rotates accordingly. After the roller rotates, it drives the grass whipping rope to rotate. During the process that the stones and large lumps of soil falling from the conveying mechanism enter the downward-moving frame body, when the grass whipping rope contacts the large lumps of soil, the large lumps of soil are broken up. After being broken up, the soil lumps continue to move downward. After being broken up by the grass whipping rope multiple times, the large lumps of soil form fine soil lumps, while the stones do not change at all when contacting the grass whipping rope, thus facilitating the better separation of the stones and the soil lumps.

[0023] 7) When the grass whipping rope needs to be replaced, first separate the bearing rod from the roller, then take out the spherical ball, and the grass whipping rope is then drawn out. Install the new spherical ball and the grass whipping rope, and the replacement can be completed. The grass whipping rope can be replaced separately without the need to replace the roller as a whole, thus reducing the usage cost.

[0024] 8) When the grass whipping rope contacts the large lumps of soil and the stones, under the action of the grass whipping rope, the large lumps of soil and the stones contact the movable plate. With the cooperation of the guide rod and the spring, the movable plate can move on the frame body, avoiding the direct contact of the large lumps of soil and the stones with the frame body, preventing the impact force of the large lumps of soil and the stones from damaging the frame body, and prolonging the service life of the frame body.

[0025] 9) The cross-section of the cross bar is triangular, so that the stones and the broken-up soil lumps can slide downward after falling on the cross bar, thus avoiding the stones and the broken-up soil lumps remaining on the cross bar, which is beneficial to the subsequent screening of the stones and the broken-up soil lumps.

[0026] 10) A receiving plate is provided on one side of the frame body and below the conveying mechanism. The receiving plate is obliquely installed inside the base body, and the lower part of the receiving plate is connected to the screening mechanism. Through the receiving plate, the soil lumps falling from the conveying mechanism can be received. After the soil lumps contact the receiving plate and slide downward along the receiving plate, the receiving plate can block the soil lumps falling from the conveying mechanism, preventing the soil lumps falling from the conveying mechanism from damaging the screening mechanism when contacting the screening mechanism, and ensuring the normal operation of the screening mechanism.

[0027] 11) A retaining plate is installed at the top of the sieve plate. The retaining plate is in a U shape. Plug plates are inserted at the ends of the retaining plate, and both ends of the plug plates are fixed to the retaining plate by bolts. Through the cooperation of the retaining plate and the plug plates, the soil lumps and the stones falling from the breaking-up mechanism can be surrounded, preventing the soil lumps and the stones from scattering outside the sieve plate and ensuring the working efficiency of the screening.

[0028] 12) The third motor operates to drive the fourth rotating shaft to rotate. The third pulley located on the fourth rotating shaft and the cylinder rotate accordingly. After the cylinder rotates, it drives the push rod and the movable frame to reciprocate on the carrier through the arc-shaped groove, thereby driving the sieve plate to swing left and right along the base through the support rod. The third pulley drives the fourth pulley to rotate through the second belt, and the carrier shaft connected to the fourth pulley rotates accordingly, thereby driving the cam to rotate. Through the rotation of the cam, the sieve plate can be driven to move up and down. The stones and the broken soil blocks falling on the sieve plate, under the action of the sieve plate, the broken soil blocks can pass through the sieve plate and fall to the ground, while the stones cannot pass through the sieve plate and are retained above the sieve plate.

[0029] 13) The circumferential surface of the cam is provided with a plurality of convex portions. When the cam rotates one circle, it can drive the sieve plate to move up and down multiple times, thereby improving the working efficiency of the screening mechanism. Description of the Drawings

[0047] A land arrangement device for ecological restoration, comprising a base body 1. A towing frame 2 is installed at one end of the base body 1. Traveling wheels 3 are installed on both sides of the end of the base body 1. A rotary tillage mechanism 4 is installed at one end of the base body 1 near the towing frame 2. A screening mechanism 7 is installed at the lower part of the end of the base body 1 far from the rotary tillage mechanism 4. A notch 11 is formed at the top of the end of the base body 1 far from the towing frame 2. A dispersing mechanism 6 is arranged above the screening mechanism 7. The dispersing mechanism 6 is installed on the base body 1. A conveying mechanism 5 is arranged between the dispersing mechanism 6 and the rotary tillage mechanism 4. The conveying mechanism 5 is obliquely installed inside the base body 1. One end of the conveying mechanism 5 far from the rotary tillage mechanism 4 passes through the notch 11 and extends above the base body 1. The dispersing mechanism 6 is located below the end of the conveying mechanism 5 far from the rotary tillage mechanism 4. The dispersing mechanism 6 is connected to the conveying mechanism 5.

[0048] The rotary tillage mechanism 4 includes a support frame 401, telescopic rods 402, a first motor 403, rotary tillage tools 405, and a transmission box 406. The number of telescopic rods 402 is two, and they are symmetrically installed on the top of the base body 1. The movable ends of the telescopic rods 402 extend into the interior of the base body 1.

The support frame 401 is in a U shape and a rotary tillage shaft 404 is rotatably installed inside it. The number of rotary tillage tools 405 is multiple, and four of them are evenly installed on the rotary tillage shaft 404 as a group. A transmission box 406 is installed inside the support frame 401. The rotary tillage shaft 404 passes through the transmission box 406 and is rotatably connected to the transmission box 406. The first motor 403 is installed on the top of the support frame 401. The power box 603 is provided with a first rotating shaft 410. The first rotating shaft 410 is rotatably installed between the support frame 401 and the transmission box 406. The top of the first rotating shaft 410 is connected to the output shaft of the first motor 403. A worm 408 is installed on the first rotating shaft 410. A worm gear 409 is installed on the rotary tillage shaft 404 located inside the power box 603. The worm gear 409 is meshed with the worm 408. When the rotary tillage mechanism 4 works, first, the telescopic rods 402 drive the support frame 401 to move downward by a certain distance. At this time, the first motor 403 works to drive the first rotating shaft 410 to rotate. The worm 408 located on the first rotating shaft 410 rotates accordingly. The worm 408 meshes with the worm gear 409 to drive the rotary tillage shaft 404 to rotate. The rotary tillage tools 405 located on the rotary tillage shaft 404 rotate accordingly. Then, the telescopic rods 402 drive the support frame 401 to move downward to the required depth. The rotary tillage tools 405 on the rotary tillage shaft 404 come into contact with the soil to loosen the soil. The soil and stones affected by the rotary tillage tools 405 are then thrown backward onto the conveying mechanism 5.

[0049] Guide blocks 407 are installed on both sides of the support frame 401. Guide grooves 718 matching the guide blocks 407 are formed on the inner side walls of the base body 1. The support frame 401 is slidably installed in the guide grooves 718 on the base body 1 through the guide blocks 407, so that the support frame 401 can always be in contact with the base body 1 through the guide blocks 407 during the up and down movement, improving the stability of the support frame 401 during movement.

[0050] The conveying mechanism 5 includes a support 501, a second motor 503, a first sprocket 504, a second sprocket 506, and a support rod 509. The number of supports 501 is two, and they are symmetrically installed on both sides of the notch 11 on the base body 1. A connecting shaft 502 is rotatably installed between the two supports 501.

The first sprockets 504 and the second sprockets 506 on the same side are connected by a chain 508. The number of the support rods 509 is multiple, and they are evenly installed between the two chains 508. When the second motor 503 works, it drives the connecting shaft 502 to rotate. The two first sprockets 504 located on the connecting shaft 502 rotate synchronously. The first sprockets 504 engage with the chain 508 to drive the chain 508 to move, and then drive the second sprockets 506 to rotate. While the chain 508 moves, the support rods 509 located on the chain 508 move synchronously. The soil and stones scattered by the rotary tillage mechanism 4 when working fall onto the support rods 509. The fine soil and stones can pass through the support rods 509 and fall on the ground, while the larger stones and soil blocks will not fall and move with the support rods 509, and finally fall into the dispersing mechanism 6. Since the chain 508 vibrates when moving, the vibration can be transmitted to the support rods 509. Through the support rods 509, the loose soil blocks can be vibrated and dispersed. The dispersed soil blocks can pass through the support rods 509 and fall on the ground, improving the working efficiency of land preparation.

[0051] A baffle 510 is provided on the periphery of the chain 508. The baffle 510 is installed inside the base body 1. The baffle 510 can block the soil blocks and stones from falling on the chain 508, causing damage and pollution to the chain 508. Under the action of the baffle 510, the direct contact between the chain 508 and the soil blocks and stones can be avoided, prolonging the service life of the chain 508 and reducing the production cost.

[0052] The crushing mechanism 6 includes a frame body 601, a power box 603, a second belt pulley 604, and a rotating roller 606. The two sides of the frame body 601 are installed on the inner side wall of the base body 1 through connecting plates 602. The power box 603 is installed on the top of the frame body 601. A third rotating shaft 610 is horizontally and rotatably installed inside the power box 603. One end of the third rotating shaft 610 extends to the outside of the power box 603. The second belt pulley 604 is installed on the third rotating shaft 610 located outside the power box 603. The second belt pulley 604 is connected to the first belt pulley 505 through a first belt 605. A cross bar 620 is installed on the inner side of the bottom of the frame body 601. A second rotating shaft 608 is rotatably installed between the cross bar 620 and the power box 603. The top end of the second rotating shaft 608 extends into the power box 603 and is installed with a first bevel gear 609. A second bevel gear 611 is installed on the third rotating shaft 610 located inside the power box 603. The second bevel gear 611 is meshed and connected with the first bevel gear 609. The rotating roller 606 is installed on the second rotating shaft 608 and is located between the power box 603 and the cross bar 620. A plurality of load-bearing rods 615 are evenly installed in the circumferential direction of the rotating roller 606. A plurality of grass ropes 616 are installed at equal distances in the vertical direction of the load-bearing rods 615. When the second motor 503 works to drive the connecting shaft 502 to rotate, the first belt pulley 505 located on the connecting shaft 502 rotates accordingly. The first belt pulley 505 drives the second belt pulley 604 to rotate through the first belt 605. The third rotating shaft 610 connected to the second belt pulley 604 rotates synchronously. The second bevel gear 611 located on the third rotating shaft 610 rotates accordingly. The second bevel gear 611 meshes with the first bevel gear 609 to drive the second rotating shaft 608 to rotate. The rotating roller 606 located on the second rotating shaft 608 rotates accordingly. After the rotating roller 606 rotates, it drives the grass ropes 616 to rotate. During the process that the stones and large soil blocks falling from the conveying mechanism 5 enter the frame body 601 and move downward, when the grass ropes 616 contact the large soil blocks, the large soil blocks are crushed. After being crushed, the soil blocks continue to move downward. After being crushed by the grass ropes 616 for many times, the large soil blocks form fine soil blocks. The stones will not change at all after contacting the grass ropes 616, which is convenient for better separation of the stones and the soil blocks.

Spherical balls 617 are installed in the placing grooves 618. One end of the grass trimming rope 616 is fixedly connected with the spherical ball 617. The grass trimming rope 616 passes through the bearing rod 615 and extends to the outside of the bearing rod 615. When the grass trimming rope 616 needs to be replaced, first separate the bearing rod 615 from the roller 606, then take out the spherical ball 617, and the grass trimming rope 616 will be drawn out accordingly. Install the new spherical ball 617 and the grass trimming rope 616, and the replacement can be completed. The grass trimming rope 616 can be replaced separately without replacing the roller 606 as a whole, thus reducing the use cost.
