Description

Technical Field

[0001] This utility model relates to the field of farmland reclamation, and in particular to a farmland reclamation and land leveling equipment. Background Technology

[0002] Farmland reclamation refers to the activities of transforming unused land, dry land, or other inefficiently used land into high-quality farmland through a series of engineering and technical measures and management methods. It is of great significance for ensuring national food security and promoting sustainable agricultural development. The main construction contents include land leveling, irrigation and drainage, and field roads.

[0003] For example, patent document CN120226492A discloses a high-standard farmland reclamation and land leveling device, including a traction harrow body. A traction frame is welded to the front side of the upper surface of the traction harrow body, and a coupling is fixed to the front side of the upper surface of the traction harrow body. Wheels are fixed at the four corners of the traction harrow body, and a stone removal component is installed inside the traction harrow body. The above device can effectively separate stones, residual roots, and larger soil clods from soil particles through the stone removal component, avoiding the impact of stones on subsequent cultivation and irrigation operations, ensuring soil purity, improving land arability, and reducing obstacles to subsequent agricultural operations.

[0004] In existing technologies, while removing stones from the field, clumps of soil and soil adhering to the stones may be carried away from the field along with the stones, causing the loss of the good topsoil. Therefore, a land leveling device that can remove stones while avoiding the removal of soil is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a farmland reclamation and land leveling device to solve the above-mentioned problems.

[0006] This utility model achieves the above objectives through the following technical solutions:

[0007] A farmland reclamation and land leveling device includes a main body with a compaction mechanism at the rear. The main body includes a main support frame with a stone collection mechanism. The stone collection mechanism includes a mesh belt conveyor assembly installed at the front of the main support frame and inclined. Several uniformly arranged baffles are fixedly connected to the surface of the mesh belt conveyor assembly. A stone collection support frame is fixedly connected to the rear of the main support frame. Several uniformly distributed stone collection bins are slidably connected to the stone collection support frame. Several lifting levers are rotatably connected to the rear of the stone collection support frame. The lifting levers are Y-shaped and have straight grooves at both ends. The straight groove at the front end of the lifting lever is hinged to the stone collection bin. A crankshaft is rotatably connected to the main support frame and hinged to the straight groove at the rear end of the lifting lever. Wheels are fixedly connected to both sides of the crankshaft. A soil screening plate is inclinedly arranged at the front of the lower end of the stone collection bin. A stone unloading plate is rotatably connected to the rear of the lower end of the stone collection bin. A linkage mechanism for driving the stone unloading plate to rotate is provided at the rear of the stone collection mechanism.

[0008] Preferably, the main body of the equipment also includes an agricultural machinery connector fixedly connected to the top front end of the main support, a shovel assembly fixedly connected to the bottom front end of the main support, and a turning roller provided behind the shovel assembly, which is rotatably connected to the main support.

[0009] Preferably, a stone-collecting motor is fixedly connected to the top of the main support, and the stone-collecting motor is connected to the rotating roller on the mesh belt conveyor assembly through a sprocket and chain. Another rotating roller on the mesh belt conveyor assembly is connected to the turning roller through a chain and sprocket.

[0010] Preferably, the pressing mechanism includes a pressing plate, with two pressing rods of the same length and arranged in parallel hinged on both sides of the pressing plate. The other end of the pressing rods is rotatably connected to the main support, and the edge of the pressing plate is set as a smooth curve.

[0011] Preferably, the rear side of the main support has two symmetrically arranged worm gears rotatably connected. The upper pressing rod is hinged to the main support and a worm wheel is fixedly connected at one end. The worm gears mesh with each other, and the rear ends of the two worm gears are connected by a sprocket and chain. A pressing motor is fixedly connected to the rear end of the main support, and the output end of the pressing motor is fixedly connected to one side of the worm gear.

[0012] Preferably, two symmetrically arranged arc-shaped chutes are fixedly connected to both sides of the lower section of the stone collection bin. A discharge connecting rod is hinged to the arc-shaped chutes, and the other end of the discharge connecting rod is hinged to the stone discharge turn plate.

[0014] The beneficial effects are as follows: Soil continuously falls onto the mesh belt conveyor assembly. Fine soil fragments fall back into the field through the holes in the mesh belt conveyor assembly, while stones and larger clumps of soil fall into the stone collection bin under the conveying of the mesh belt conveyor assembly and the baffle plate. The crankshaft drives the lifting lever to deflect, and the lifting lever drives the stone collection bin to rise and fall. During the reciprocating rising and falling process, stones collide with each other and stones collide with clumps of soil.

Therefore, they should not be construed as limitations on this utility model.

[0029] The present invention will be further described below with reference to the accompanying drawings:

[0030] like Figures 1-8As shown, a farmland reclamation and land leveling device includes a main body with a compaction mechanism at the rear. The main body includes a main support 101, on which a stone collection mechanism is mounted. The stone collection mechanism includes a mesh belt conveyor assembly 202 installed at the front of the main support 101 and inclined. Several evenly distributed baffle plates 203 are fixedly connected to the surface of the mesh belt conveyor assembly 202. A stone collection support frame 105 is bolted to the rear of the main support 101. Several evenly distributed stone collection bins 204 are slidably connected to the stone collection support frame 105. The top of each stone collection bin 204 is funnel-shaped. Several lifting levers 209 are rotatably connected to the rear side of the stone collection support frame 105. The lifting levers 209 are Y-shaped, and both ends of the lifting levers 209 have straight grooves. The front straight groove of the lifting lever 209 is hinged to the stone collection bin 204. A crankshaft 210 is rotatably connected to the main support 101, and the crankshaft 210 is hinged to the rear straight groove of the lifting levers 209. Wheels 211 are fixedly connected to both sides of the crankshaft 210. A soil screening plate 205 is inclinedly installed on the lower front side of the stone collection bin 204, and a stone unloading turntable 206 is rotatably connected to the lower rear side of the stone collection bin 204. A drive mechanism is provided at the rear of the stone collection mechanism. The linkage mechanism of the rotating stone unloading plate 206 causes the uneven surface soil to be turned up and continuously fall onto the mesh belt conveyor 202 under the action of the blade assembly 103 during the forward movement of the main support 101 of the agricultural machinery. The fine soil falls back into the field through the holes on the mesh belt conveyor 202, while the stones and larger clumps of soil fall into the stone collection bin 204 under the conveying of the mesh belt conveyor 202 and the baffle plate 203. During the forward movement of the main support 101, the wheels 211 rotate accordingly, driving the crankshaft 210 to rotate, and the crankshaft 210 drives the lifting mechanism. The lifting lever 209 deflects, and the front end of the lifting lever 209 drives the stone collection bin 204 to reciprocate. During the reciprocating lifting process, stones collide with each other and with clumps of soil. As a result, the soil adhering to the stones and the clumps of soil are broken down into fine fragments and fall back into the field through the sieve plate 205. The crankshaft 210 drives the lifting lever 209 to deflect. The motion structure of the lifting lever 209 driving the stone collection bin 204 to rise and fall has a quick-return characteristic. Through the quick-return characteristic, the collision between stones and stones and clumps of soil in the stone collection bin 204 can be increased, thereby increasing the soil recycling efficiency.

[0031] The main body of the equipment also includes an agricultural machinery connector 102 fixedly connected to the top front end of the main support 101. A shovel assembly 103 is fixedly connected to the bottom front end of the main support 101. A turning roller 104 is set behind the shovel assembly 103. The turning roller 104 is rotatably connected to the main support 101. Personnel connect the agricultural machinery connector 102 to the rear of agricultural machinery such as tractors through pins. As the main support 101 drives the shovel assembly 103 forward, the shovel assembly 103 shovels up the uneven soil and stones on the field surface. The soil shoveled up later squeezes the soil shoveled up earlier into the mesh belt conveyor assembly 202. After the field is leveled, the surface soil is loosened by the action of the turning roller 104. Finally, the compaction mechanism smooths the loose soil.

[0032] A stone-collecting motor 201 is fixedly connected to the top of the main support 101. The stone-collecting motor 201 is connected to the rotating roller on the mesh belt conveyor assembly 202 through a sprocket and chain. Another rotating roller on the mesh belt conveyor assembly 202 is connected to the turning roller 104 through a chain and sprocket. The stone-collecting motor 201 drives the mesh belt conveyor assembly 202 to rotate through chain drive. At the same time, the mesh belt conveyor assembly 202 drives the turning roller 104 to rotate through chain drive.

[0033] The pressing mechanism includes a pressing plate 302. Two pressing rods 301 of the same length and arranged in parallel are hinged to both sides of the pressing plate 302. The other end of the pressing rods 301 is rotatably connected to the main support 101. The edge of the pressing plate 302 is set as a smooth curve. The main support 101, the two pressing rods 301, and the pressing plate 302 form a parallel four-bar linkage mechanism, which can ensure that the angle between the pressing plate 302 and the main support 101 is fixed no matter where the pressing plate 302 is, thus making it easy for the staff to control the position of the pressing plate 302.

[0034] Two symmetrically arranged worm gears 303 are rotatably connected to the rear side of the main support 101. The upper end of the pressing connecting rod 301, which is hinged to the main support 101, is also fixedly connected to a worm wheel 304. The worm gears 303 mesh with each other, and the rear ends of the two worm gears 303 are connected by a sprocket and chain. A pressing motor 305 is fixedly connected to the rear end of the main support 101. The output end of the pressing motor 305 is fixedly connected to one of the worm gears 303. The pressing motor 305 drives one of the worm gears 303 to rotate. At the same time, the worm gear 303 drives the other worm gear 303 to rotate synchronously and in the same direction through chain transmission. The worm gear 303 drives the worm wheel 304 to rotate, and the worm wheel 304 drives the pressing connecting rod 301 to rotate. In this way, the height of the pressing plate 302 can be adjusted. The self-locking property of the worm gears 303 and worm wheel 304 ensures the stability of the pressing plate 302 during the leveling process.

[0035] Two symmetrically arranged arc-shaped chute 208s are fixedly connected to both sides of the lower section of the stone collection bin 204. A discharge connecting rod 207 is hinged to the arc-shaped chute 208, and the other end of the discharge connecting rod 207 is hinged to the stone unloading turntable 206. The linkage mechanism includes an L-shaped push frame 401. A vertical straight chute frame 403 is fixedly connected to the front end of the L-shaped push frame 401. The vertical straight chute frame 403 is hinged to the outer side of the upper end of the discharge connecting rod 207. Two symmetrically arranged horizontal screws 402 are rotatably connected to the top of the main support 101. The rear end of the horizontal screws 402 is fixedly connected to the worm gear 303. The L-shaped pusher 401 is threadedly connected to the horizontal screw 402. During the rotation of the worm gear 303, the horizontal screw 402 is driven to rotate. The horizontal screw 402 drives the L-shaped pusher 401 to move through the threaded connection. The movement of the L-shaped pusher 401 drives the vertical straight groove frame 403 to move horizontally. The vertical straight groove frame 403 drives the unloading connecting rod 207 to move along the arc-shaped slide 208. The unloading connecting rod 207 drives the lifting lever 209 to flip open. Thus, when the pressing plate 302 rises, the lifting lever 209 opens, and the stones inside the stone collection bin 204 are released.

[0036] Working principle: Operators connect the agricultural machinery connector 102 to the rear of a tractor or other agricultural machinery via a pin. As the main support 101 drives the blade assembly 103 forward, the blade assembly 103 scoops up uneven soil and stones from the field surface. The soil scooped up later compresses the previously scooped soil and incorporates it into the mesh belt conveyor assembly 202. Fine soil fragments fall back into the field through the holes in the mesh belt conveyor assembly 202, while stones and larger clumps of soil are conveyed by the mesh belt conveyor assembly 202 and the baffle plate 203 into the stone collection bin 204. During the forward movement of the main support 101, the vehicle... Wheel 211 rotates, driving crankshaft 210 to rotate. Crankshaft 210 drives lifting lever 209 to deflect. The front end of lifting lever 209 drives stone collection bin 204 to reciprocate. During this reciprocating motion, stones collide with each other and with clumps of soil, breaking down the soil adhering to the stones and clumps into smaller pieces that fall back into the field through sieve plate 205. After the field is leveled, stone collection motor 201 drives mesh belt conveyor 202 to rotate via chain drive. Simultaneously, mesh belt conveyor 202 rotates via chain drive. The tilling roller 104 rotates, loosening the surface soil. The compaction motor 305 drives one worm gear 303 to rotate, simultaneously driving another worm gear 303 to rotate synchronously in the same direction via chain drive. The worm gear 303 drives the worm wheel 304 to rotate, which in turn drives the compaction connecting rod 301. The main support 101, the two compaction connecting rods 301, and the compaction plate 302 form a parallel four-bar linkage. This ensures that the angle between the compaction plate 302 and the main support 101 remains fixed regardless of the compaction plate's position, allowing for adjustment of the compaction plate's height. The compaction mechanism smooths out the loose soil. After the leveling work is completed, the stones in the stone collection bin 204 need to be removed. During the rotation of the worm gear 303, the horizontal screw 402 is driven to rotate. The horizontal screw 402 drives the L-shaped push frame 401 to move through the threaded connection. The movement of the L-shaped push frame 401 drives the vertical straight groove frame 403 to move horizontally. The vertical straight groove frame 403 drives the unloading connecting rod 207 to move along the arc-shaped slide 208. The unloading connecting rod 207 drives the lifting lever 209 to flip open. Thus, when the compaction plate 302 rises, the lifting lever 209 opens, and the stones inside the stone collection bin 204 are removed.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
