Description

Technical Field

[0001] The utility model relates to the technical field of land leveling equipment, in particular to a land leveling equipment. Background Art

[0002] Land leveling equipment for house construction refers to equipment used to level and compact the construction land. In house construction projects, land leveling and compaction are very important steps, which can improve the stability and bearing capacity of the foundation, prevent foundation settlement and deformation, and ensure the safety and stability of the building.

[0003] A road roller, also known as a soil roller, is a type of road construction equipment, which is divided into two types: steel wheel type and tire type. Among engineering machinery, road rollers belong to the category of road equipment and are widely used in filling and compaction operations of large-scale engineering projects such as high-grade highways, railways, airport runways, dams, and stadiums. They can roll sandy, semi-viscous and viscous soils, roadbed stabilized soils, and asphalt concrete pavement layers. With the gravity of the machine itself, road rollers are suitable for various compaction operations, causing the rolled layer to be permanently deformed and compacted.

[0004] When the existing land leveling equipment is in use, the soil is easily compacted and cracked due to the reduction of organic matter in the soil, and the soil appears to be in a lumpy state. When the land leveling equipment is flattening the agglomerated soil, large gaps will remain between the lumps of soil, and the soil in the gaps is prone to collapse, resulting in the flattened land being loose and bumpy, affecting the quality of construction. In addition, when the land leveling equipment is being transported or the flattening direction is adjusted, the excavation equipment cannot move off the ground, and the excavation equipment will damage the bottom surface that does not need to be flattened, resulting in low construction efficiency. Utility Model Content

[0005] 1. Technical issues to be resolved

[0006] In view of the deficiencies in the prior art, the utility model provides a land leveling device which has the advantages of digging and loosening agglomerated soil, thereby solving the problems of large gaps in agglomerated soil after being flattened and the inability of the digging device to be lifted off the ground.

[0007] (II) Technical solution

[0008] In order to achieve the above-mentioned goal, the utility model not only solves the problem of large gaps and lack of compactness in the lumped soil after being flattened, but also ensures the convenience of equipment movement. The utility model provides the following technical solutions: a land leveling device, including a roller, on which a soil crushing adjustment mechanism is installed, the soil crushing adjustment mechanism includes a limiting frame connected to the roller, a lifting block is slidably connected in the limiting frame, a threaded rod is screwed on the lifting block, a lifting frame is connected to one side of the lifting block, an excavation drum is rotatably connected to the lifting frame, and an excavation blade is connected to the excavation drum.

[0009] As a preferred solution of the land leveling equipment of the utility model, a support wheel is connected to the lower surface of the limit frame, and a motor is sleeved on one end of the threaded rod.

[0010] As a preferred solution of the land leveling equipment of the utility model, a slide groove is provided in the lifting frame, a limiting block is slidably connected in the slide groove, and a hole-piercing frame is connected to the limiting block.

[0011] As a preferred solution of the land leveling equipment of the utility model, a spring sheet is arranged on the upper surface of the hole-piercing frame, a fixing block is connected to the lifting frame, and a spring sheet is arranged between the hole-piercing frame and the fixing block.

[0012] As a preferred solution of the land leveling equipment of the utility model, a rack is connected to the side of the piercing frame close to the digging drum, the rack is intermittently meshed with a gear, and the gear is connected to both ends of the digging drum.

[0013] As a preferred solution of the land leveling equipment of the utility model, a steel needle is sleeved on the hole-piercing frame, and a flattening drum is rotatably connected to the side of the roller away from the digging drum.

[0014] Compared with the known prior art, the technical solution provided by the utility model has the following beneficial effects:

[0015] 1. By setting a row of steel needles on the piercing frame, the land that needs to be flattened is pierced evenly intermittently, which increases the porosity of the soil that needs to be flattened, making it easier for the excavation drum to drive the excavation blade to rotate and excavate the land full of holes. The loose soil can be broken up, and the flattening roller can be used to flatten the land, which helps to press the land more tightly and firmly.

[0016] 2. The threaded rod is driven to rotate through the output end of the motor, and the threaded rod is driven to drive the screwed lifting block to move upward along the limit frame through the rotation of the threaded rod, so that the middle lifting frame drives the excavation drum and the excavation blade to move upward, and the limit block on one side of the hole-piercing frame slides up and down along the slide groove on the lifting frame. When the lifting frame rises, it will drive the hole-piercing frame to rise together. The unified lifting off the ground can reduce the risk of damage caused by collision between the equipment and the ground, protect the equipment and the surrounding land that does not need to be flattened, facilitate the adjustment of the flattening direction of the equipment, and play a supporting role through the support wheels, so that the equipment can be driven to the designated position that needs to be flattened.

DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] The utility model is further described below in conjunction with embodiments.

[0025] Example 1

[0026] Reference Figure 1-2 , which is the first embodiment of the utility model, provides a land leveling device, including a road roller 100, on which a soil crushing adjustment mechanism 200 is installed, and the soil crushing adjustment mechanism 200 includes a limit frame 201 connected to the road roller 100, and a lifting block 202 is slidably connected in the limit frame 201, and a threaded rod 203 is screwed on the lifting block 202, and a lifting frame 204 is connected to one side of the lifting block 202, and an excavation drum 205 is rotatably connected to the lifting frame 204, and an excavation blade 206 is connected to the excavation drum 205. The threaded rod 203 rotates to drive the screwed lifting block 202 to move upward along the limit frame 201, so that the lifting frame 204 in the middle drives the excavation drum 205 and the excavation blade 206 to move upward and break away from the ground.

[0027] The lower surface of the limiting frame 201 is connected with a support wheel 207 , and one end of the threaded rod 203 is sleeved with a motor 208 . The output end of the motor 208 drives the threaded rod 203 to rotate, thereby controlling the lifting and lowering of the lifting frame 204 , and the support wheel 207 plays a supporting role.

[0028] During use, the output end of the motor 208 drives the threaded rod 203 to rotate, and the rotation of the threaded rod 203 drives the screwed lifting block 202 to move upward along the limit frame 201, so that the middle lifting frame 204 drives the excavating roller 205 and the excavating blade 206 to move upward, and the limit block 210 on one side of the hole-piercing frame 211 slides up and down along the slide groove 209 on the lifting frame 204, which limits the hole-piercing frame 211. When the lifting frame 204 rises, it will drive the hole-piercing frame 211 to rise together and break contact with the ground, and play a supporting role through the support wheel 207, which makes it convenient for the equipment to travel to the designated position that needs to be flattened.

[0029] Example 2

[0030] Reference Figure 1-4 , which is the second embodiment of the utility model, provides a land leveling device, including a lifting frame 204 with a slide groove 209, a limiting block 210 slidably connected in the slide groove 209, a hole-piercing frame 211 is connected to the limiting block 210, and the limiting block 210 on one side of the hole-piercing frame 211 slides up and down along the slide groove 209 on the lifting frame 204, which limits the hole-piercing frame 211. When the lifting frame 204 rises, it will drive the hole-piercing frame 211 to rise together.

[0031] The upper surface of the hole-piercing frame 211 is provided with a spring piece 212, and the lifting frame 204 is connected with a fixed block 213. The spring piece 212 is provided between the hole-piercing frame 211 and the fixed block 213. When the hole-piercing frame 211 moves upward along the slide groove 209, the spring piece 212 between the hole-piercing frame 211 and the fixed block 213 is squeezed.

[0032] A rack 215 is connected to the side of the hole-piercing frame 211 close to the excavating drum 205, and the rack 215 is intermittently meshed with a gear 216. The gear 216 is connected to both ends of the excavating drum 205. When the excavating drum 205 is driven to rotate clockwise by the driving system of the equipment, the gear 216 intermittently drives the meshed rack 215 to move upward, so that the hole-piercing frame 211 moves upward along the slide groove 209. When the gear 216 and the rack 215 are not meshed, the squeezed spring piece 212 quickly pushes the hole-piercing frame 211 downward under the reaction force.

[0033] A steel needle 214 is sleeved on the piercing frame 211, and a flattening roller 217 is rotatably connected to the side of the roller 100 away from the digging roller 205. By arranging a row of steel needles 214 on the piercing frame 211, holes are pierced evenly on the land that needs to be flattened intermittently, and the digging blade 206 is driven by the digging roller 205 to rotate to dig the loosened land, and the land is flattened by the flattening roller 217.

[0034] During use, when the excavating drum 205 is driven to rotate clockwise by the driving system of the equipment, the gear 216 intermittently drives the meshing rack 215 to move upward, so that the piercing frame 211 moves upward along the slide groove 209, and the spring piece 212 between the piercing frame 211 and the fixed block 213 is squeezed. When the gear 216 and the rack 215 are not meshed, the squeezed spring piece 212 quickly pushes the piercing frame 211 to move downward under the reaction force. By arranging a row of steel needles 214 on the piercing frame 211, the land that needs to be flattened is intermittently pierced with holes evenly, and the excavating drum 205 drives the excavating blade 206 to rotate to excavate the loosened land, and the flattening drum 217 is used to flatten the land.

[0035] The remaining structure is the same as that of Example 1.
