A leveling device for land consolidation

Abstract

This utility model discloses a leveling device for land consolidation, relating to the field of land development equipment technology. The device includes a protective box with several handles fixedly connected to its outer wall. A control panel is fixedly connected to the top outer wall of the protective box. The device incorporates a support rod and a positioning rod. A motor drives a first crankshaft to rotate, simultaneously causing the support rod to rotate around the outer side of the crankshaft. The rotation of the support rod drives the positioning rod, which in turn moves the connecting seat, causing the connecting seat to move the connecting plate. This achieves sufficient buffer space between the support rod and the positioning rod, absorbing the reaction force generated when the leveling roller impacts the ground. This prevents damage to the cam caused by the cam's contour curve forcibly constraining the roller's movement trajectory.

Description

Technical Field

[0001] This utility model belongs to the field of land development equipment technology, and in particular relates to a leveling device for land consolidation. Background Technology

[0002] According to the published patent CN218977226U, a leveling device for land consolidation is described. A cover is welded to the bottom of the top plate, and the bottom of the cover is open. Support blocks are bolted to the left and right sides of the cover near the bottom. First side plates are welded to the bottom of the top plate near the left and right sides. Second side plates are movably connected to the bottom of each of the two first side plates, and a straight plate connects the two second side plates. A cam is provided between the two first side plates. This improved leveling device can drive the leveling roller to rotate and move up and down, thereby achieving uniform leveling of the land. It effectively improves leveling efficiency and avoids incomplete leveling caused by using a single simple leveling plate, thus improving its practicality. It can also uniformly spray nutrient solution, effectively improving its working efficiency and usability. However, it still has the following shortcomings:

[0003] After the above equipment is completed, it simply drives the leveling roller to move back and forth by rotating the cam. However, since the movement trajectory of the leveling roller is forcibly constrained by the contour curve of the cam, the reaction force generated when the leveling roller contacts the ground will be directly transmitted to the cam, causing the cam to be damaged. Utility Model Content

[0004] The purpose of this utility model is to provide a leveling device for land consolidation. By using a pressing mechanism and a shock-absorbing mechanism, it solves the problem that the reaction force generated when the leveling roller contacts the ground is directly transmitted to the cam due to the forced constraint of the movement trajectory of the leveling roller by the profile curve of the cam, which leads to damage to the cam.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a leveling device for land consolidation, including a protective box, with several handles fixedly connected to the outer wall of the protective box, and a control panel fixedly connected to the top outer wall of the protective box.

[0007] The inner wall of the protective box is provided with a pressing mechanism, which includes a motor. The outer wall of the motor is fixedly connected to the inner wall of the protective box. The output end of the motor is fixedly connected to a first crankshaft via a coupling. A first pulley is fixedly connected to the outer wall of the first crankshaft. A belt is driven through the inner wall of the first pulley. A second pulley is driven through the outer wall of the belt away from the first pulley. A second crankshaft is fixedly connected to the outer wall of the second pulley. Several support rods are rotatably connected to the outer walls of the first and second crankshafts. A positioning rod is rotatably connected to the outer wall of the support rod. A connecting seat is rotatably connected to the bottom outer wall of the positioning rod. A shock-absorbing mechanism is provided on the outer wall of the connecting plate.

[0008] Furthermore, a connecting plate is fixedly connected to the bottom outer wall of the connecting seat, a limiting groove is formed on the inner wall of the positioning rod, a limiting rod is slidably connected to the inner wall of the limiting groove, the outer wall of the first crankshaft is rotatably connected to the inner wall of the protective box, the outer wall of the second crankshaft is rotatably connected to the inner wall of the protective box, and the outer wall of the connecting plate is slidably connected to the inner wall of the protective box.

[0009] Furthermore, the shock absorption mechanism includes a first positioning block, the outer wall of the first positioning block is fixedly connected to the outer wall of the connecting plate, a first connecting rod is rotatably connected to the outer wall of the first positioning block, a second positioning block is rotatably connected to the outer wall of the first connecting rod away from the first positioning block, and a third positioning block is fixedly connected to the top outer wall of the second positioning block.

[0010] Furthermore, the inner wall of the protective box is provided with a first sliding groove, the outer wall of the third positioning block is slidably connected to the inner wall of the first sliding groove, and a plurality of first soil pressing rollers are rotatably connected to the outer wall of the second positioning block.

[0011] Furthermore, a damper is fixedly connected to the top outer wall of the second positioning block, the outer wall of the damper is fixedly connected to the outer wall of the connecting plate, a spring is fixedly connected to the outer wall of the damper, and the outer wall of the spring is fixedly connected to the outer wall of the second positioning block.

[0012] Furthermore, a second sliding groove is provided on the inner wall of the first connecting rod, a positioning shaft is slidably connected to the inner wall of the second sliding groove, and a first connecting rod is rotatably connected to the outer wall of the positioning shaft.

[0013] Furthermore, a connecting block is rotatably connected to the outer wall of the end of the first connecting rod away from the positioning shaft, the outer wall of the connecting block is fixedly connected to the outer wall of the connecting plate, and a second connecting rod is rotatably connected to the outer wall of the positioning shaft.

[0014] Furthermore, a fourth positioning block is rotatably connected to the outer wall of the end of the second connecting rod away from the positioning axis, and a plurality of second soil pressing rollers are rotatably connected to the inner wall of the fourth positioning block.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model incorporates a support rod and a positioning rod. The motor drives the first crankshaft to rotate, simultaneously causing the support rod to rotate around the outer edge of the crankshaft. The rotation of the support rod drives the positioning rod, which in turn moves the connecting seat, causing the connecting seat to move the connecting plate. This creates sufficient buffer space between the support rod and the positioning rod, absorbing the reaction force generated when the leveling roller impacts the ground. This prevents the force from being directly transmitted to the crankshaft, thus preventing damage to the cam caused by the cam's contour curve forcibly constraining the leveling roller's movement trajectory.

[0017] 2. This utility model incorporates a damper and a spring. During the movement of the second positioning block, the damper at the top is compressed, thus relieving the pressure on the second positioning block. Simultaneously, by setting the damper to automatically compress the outer spring when compressed, the elasticity of the spring increases the damper's ability to relieve pressure. This prevents the reaction force generated when the leveling roller contacts the ground during operation from being directly transmitted to the connection point. With continuous operation, this reaction force will be continuously transmitted to the connection point, causing the wear at the connection point to increase and thus reducing the service life of the device.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0028] Please see Figure 1-5 As shown, this utility model is a leveling device for land consolidation, including a protective box 1. Several handles 101 are fixedly connected to the outer wall of the protective box 1, and a control panel 102 is fixedly connected to the top outer wall of the protective box 1. The control panel 102 is used to control the automatic start of the motor 201.

[0029] The inner wall of the protective box 1 is provided with a pressing mechanism 2, which includes a motor 201. The motor 201 is fixedly connected to the outer wall of the protective box 1. The output end of the motor 201 is fixedly connected to a first crankshaft 202 via a coupling. A first pulley 203 is fixedly connected to the outer wall of the first crankshaft 202. A belt 204 is driven through the inner wall of the first pulley 203. A second pulley 205 is driven through the outer wall of the end of the belt 204 away from the first pulley 203. The first pulley 203 and the second pulley 205 are simultaneously connected through the two ends of the belt 204, and the belt 204 drives the first pulley 203 and the second pulley 205 to rotate simultaneously. A second crankshaft 206 is fixedly connected to the outer wall of the second pulley 205. Several support rods 207 are rotatably connected to the outer walls of the first crankshaft 202 and the second crankshaft 206. The rotation of the first crankshaft 202 and the second crankshaft 206 in the same direction will drive the support rods 207. 7. The support rod 207 is rotatably connected to a positioning rod 208 on its outer wall. A connecting seat 209 is rotatably connected to the bottom outer wall of the positioning rod 208. During the movement of the support rod 207, the positioning rod 208 rotates around the support rod 207. A shock-absorbing mechanism 3 is provided on the outer wall of the connecting plate 210. The connecting plate 210 is fixedly connected to the bottom outer wall of the connecting seat 209. The movement of the positioning rod 208 moves the connecting plate 210. A limiting groove 211 is formed in the inner wall, and a limiting rod 212 is slidably connected to the inner wall of the limiting groove 211. The limiting rod 212 moves along the inside of the limiting groove 211, thereby limiting the movement range of the positioning rod 208. The limiting rod 212 is fixedly connected to the inner wall of the protective box 1. The outer wall of the first crankshaft 202 is rotatably connected to the inner wall of the protective box 1. The outer wall of the second crankshaft 206 is rotatably connected to the inner wall of the protective box 1. The outer wall of the connecting plate 210 is slidably connected to the inner wall of the protective box 1.

[0030] The shock absorption mechanism 3 includes a first positioning block 301. The outer wall of the first positioning block 301 is fixedly connected to the outer wall of the connecting plate 210. A first connecting rod 302 is rotatably connected to the outer wall of the first positioning block 301. A second positioning block 303 is rotatably connected to the outer wall of the end of the first connecting rod 302 away from the first positioning block 301. The movement of the first positioning block 301 pushes the first connecting rod 302 to rotate around the first positioning block 301, while simultaneously driving the second positioning block 303 to move. A third positioning block 305 is fixedly connected to the top outer wall of the second positioning block 303. A first sliding groove 306 is provided on the inner wall of the protective box 1. The movement of the second positioning block 303 pushes the third positioning block 305 to move along the inside of the first sliding groove 306, thereby stabilizing the second positioning block 303. The movement range of block 303 is limited. The outer wall of the third positioning block 305 is slidably connected to the inner wall of the first chute 306. Several first pressing rollers 304 are rotatably connected to the outer wall of the second positioning block 303. The movement of the second positioning block 303 pushes the two first pressing rollers 304 at the bottom to flatten the ground. A damper 307 is fixedly connected to the top outer wall of the second positioning block 303. The outer wall of the damper 307 is fixedly connected to the outer wall of the connecting plate 210. A spring 308 is fixedly connected to the outer wall of the damper 307. The damper 307 is pre-set to automatically compress the outer spring 308 when it is squeezed. The elasticity of the spring 308 is used to relieve the pressure on the second positioning block 303 when it moves. The outer wall of the spring 308 is fixedly connected to the outer wall of the second positioning block 303.

[0031] The inner wall of the first connecting rod 302 is provided with a second sliding groove 309. A positioning shaft 310 is slidably connected to the inner wall of the second sliding groove 309. A first connecting rod 311 is rotatably connected to the outer wall of the positioning shaft 310. A connecting block 312 is rotatably connected to the outer wall of the end of the first connecting rod 311 away from the positioning shaft 310. By rotating the first connecting rod 311 around the outer side of the connecting block 312, the first connecting rod 311 pushes the positioning shaft 310 to move along the interior of the second sliding groove 309. The rotation of the first connecting rod 302 is also controlled by the first connecting rod 311. The outer wall of the connecting block 312 is fixedly connected to the outer wall of the connecting plate 210. The outer wall of the positioning shaft 310 is rotatably connected to the second connecting rod 313. The outer wall of the second connecting rod 313 away from the positioning shaft 310 is rotatably connected to the fourth positioning block 314. The movement of the positioning shaft 310 pushes the second connecting rod 313 to rotate around the outside of the positioning shaft 310, and pushes the fourth positioning block 314 to move. The inner wall of the fourth positioning block 314 is rotatably connected to several second compaction rollers 315, which compact the ground.

[0032] One specific application of this embodiment is:

[0033] When the operator needs to use the equipment, they push the handle 101 to move the entire device. The control panel 102 on the surface of the protective box 1 controls the speed and rotation time of the motor 201. The motor 201 drives the first crankshaft 202 to rotate, simultaneously pushing the support rod 207 to rotate around the outer side of the first crankshaft 202. The rotation of the support rod 207 drives the positioning rod 208 to move the connecting seat 209, which in turn pushes the connecting plate 210. During the movement of the positioning rod 208, the limiting rod 212 moves along the inside of the limiting groove 211, thus limiting the range of movement of the positioning rod 208. This controls the movement range of the connecting plate 210. During the rotation of the first crankshaft 202, the first pulley 203 rotates. Simultaneously, the two ends of the belt 204 connect the first pulley 203 and the second pulley 205. The belt 204 drives both the first pulley 203 and the second pulley 205 to rotate simultaneously. During the rotation of the second pulley 205, the second crankshaft 206 rotates inside the protective box 1. The second crankshaft 206 connects to the same parts as the first crankshaft 202, thus the rotation creates the same motion trajectory and achieves the same final effect. Furthermore, the support rod 207 connects the first crankshaft 202 and the second crankshaft 206. At the bend, the rotation of the first crankshaft 202 and the second crankshaft 206 drives the connecting plate 210 to move up and down. During the movement of the connecting plate 210, the first positioning block 301 is pushed to move. The movement of the first positioning block 301 pushes multiple first connecting rods 302 to rotate around the outside of the first positioning block 301. The rotation of the first connecting rods 302 pushes the second positioning block 303 to move, while the first soil roller 304 contacts the ground. If the ground is uneven, the second positioning block 303 is pushed upward to move in the opposite direction, while the third positioning block 305 moves along the first sliding groove 306 inside the protective box 1, thereby limiting the movement range of the second positioning block 303. Simultaneously, during the movement of the second positioning block 303, it compresses the top damper 307, using the damper 307 to relieve the pressure on the second positioning block 303. Furthermore, by configuring the damper 307 to automatically compress the outer spring 308 when compressed, the elasticity of the spring 308 increases the damper 307's ability to relieve pressure. During the rotation of the first connecting rod 302, it pushes the positioning shaft 310 to move. Simultaneously, the positioning shaft 310 pushes the first connecting rod 311 to rotate around the outer side of the connecting block 312, thereby allowing the first connecting rod 311 to push the positioning shaft 310 to move along the interior of the second slide groove 309, and enabling the first connecting rod 311 to support the rotation of the first connecting rod 302.During the movement of the positioning shaft 310, the second connecting rod 313 is pushed to rotate around the outer side of the positioning shaft 310. The rotation of the second connecting rod 313 pulls the fourth positioning block 314 upwards. The movement of the fourth positioning block 314 drives the second pressing roller 315 to maintain pressure on the ground. Thus, the free movement of multiple first pressing rollers 304 and second pressing rollers 315 adapts to different ground steepness levels, maintaining stable pressure.
