Detailed implementation manners

[0040] The following is a specific introduction to the present invention in conjunction with the accompanying drawings and specific embodiments:

[0041] As Figures 1 - 15 shown, a ground leveling device for land improvement according to the present invention includes a side cover 1. A hollow drum 2 is rotatably connected to the inner side of the side cover 1. A cylinder barrel 3 is fixedly connected to the top of the side cover 1 close to the hollow drum 2. A fixed frame 4 is fixedly connected to the front side of the side cover 1. A pulling arm 5 for connecting a traction device is obliquely fixed to the front side of the fixed frame 4. A PLC controller is fixedly connected to the pulling arm 5;

[0042] Driving components are provided on both sides of the hollow drum 2 close to the side housing 1. The driving components include water distribution pipe racks 61 embedded on both sides of the hollow drum 2 and rotatably matched with the side housing 1, and pulley wheels 62 fixed to the outer ends of the water distribution pipe racks 61. Combing components are provided on both sides inside the fixed frame 4. The combing components include reciprocating lead screws 71 rotatably arranged inside the fixed frame 4, and lead screw sleeves 72 threadedly connected to the reciprocating lead screws 71. Miscellaneous stones, plants and other sundries in front of the hollow drum 2 are swept and combed to the periphery of the flat area, which is beneficial to the effective leveling work of the hollow drum 2 on the ground, so as to prevent the hollow drum 2 from pressing miscellaneous stones, plants and other sundries into the ground, resulting in uneven ground and improving the leveling quality of the ground;

[0043] A suction component is provided on the cylinder barrel 3. The suction component includes a differential gear 81 meshed on the top of the pulley wheel 62, and a driving gear 82 fixed to the inner side of the differential gear 81 through a fixing rod. A regulation component for pressure regulation of the hollow drum 2 is provided outside the suction component. The regulation component includes a six-way valve 91 communicated with the inner end of the cylinder barrel 3, and a suction pipe 92 communicated with both ends of the six-way valve 91. The weight of the hollow drum 2 is adaptively regulated according to the soft and loose material of the current ground foundation to be leveled, which is beneficial to the leveling work of the ground foundation with softer or harder geology.

[0044] As Figures 5 - 13 shown, the driving component further includes a synchronous wheel 63 drivingly connected to the pulley wheel 62 through a synchronous belt and rotatably matched with the side housing 1. A cross bar 64 rotatably matched with the side housing 1 and the fixed frame 4 is fixedly connected to the inner side of the synchronous wheel 63. Two water distribution pipe racks 61 following the synchronous rotation of the hollow drum 2 drive two groups of pulley wheels 62 to rotate. The two groups of pulley wheels 62 drive the cross bars 64 on the two groups of synchronous wheels 63 to rotate through two synchronous belts. A main gear 65 is fixedly connected to the cross bar 64, and a sub-gear 66 is meshed with the outer side of the main gear 65. The cross bar 64 drives the main gear 65 and the sub-gear 66 to rotate successively;

[0045] The combing assembly also includes rack plates 73 fixed on both sides of the screw sleeve 72. The pinion gear 66 drives the screw sleeve 72 on the reciprocating screw 71 to move back and forth horizontally, and the screw sleeve 72 drives the two sets of rack plates 73 to move back and forth horizontally, and the outer side of the rack plate 73 is meshed with a steering gear 74 that rotates with the fixed frame 4. The bottom of the steering gear 74 is fixedly connected to a swing arm 75 through a fixed rod. The two sets of rack plates 73 that move back and forth horizontally drive the swing arms 75 on the two sets of steering gears 74 to rotate alternately in the forward and reverse directions, and the swing arms 75 The bottom of the hollow drum 2 is slidably connected with a frame 76, and the bottom array of the frame 76 is provided with a toggle tooth. The swing arm 75 that rotates alternately in the forward and reverse directions drives the two sets of frames 76 to expand outward and reset inward to reciprocate. The two sets of frames 76 that expand outward and reset inward to reciprocate clean and comb the debris such as stones and plants in front of the hollow drum 2 to the periphery of the flattened area through the toggle teeth, which is conducive to the effective flattening work of the hollow drum 2 on the ground, so as to prevent the hollow drum 2 from pressing the debris such as stones and plants into the ground, resulting in uneven ground, thereby improving the flattening quality of the ground;

[0046] The water distribution pipe rack 61 is distributed in a triangular equidistant state along the horizontal axis of the hollow drum 2, so that the water distribution pipe rack 61 is always connected with the water in the hollow drum 2, and a first liquid level probe 11 is fixed diagonally on the inner side of the water distribution pipe rack 61 to monitor the water level change in the hollow drum 2 in real time. A T-shaped slide groove 12 is provided at the center of the inner cavity of the fixed frame 4, and the inner cavity of the T-shaped slide groove 12 is slidably connected with a T-shaped slide bar 13 fixedly matched with the screw sleeve 72, which plays a role of sliding limit for the screw sleeve 72, thereby improving the reciprocating displacement stability of the screw sleeve 72 and the rack plate 73. The other end of the swing arm 75 is rotatably connected with a convex head, and both sides of the convex head are provided with a T-shaped sliding mouth. The top of the skeleton 76 is provided with a T-shaped guide rail 14 slidably matched with the T-shaped sliding mouth, so that the swing arm 75 drives the skeleton 76 to swing back and forth horizontally through the convex head, thereby improving the swinging smoothness of the skeleton 76.

[0047] A connecting piece 15 is fixedly connected to the inner side of the skeleton 76, and a movable sleeve 16 that movably cooperates with the cross bar 64 is fixedly connected to the connecting piece 15. The movable sleeve 16 serves as a sliding support for the swing arm 75 that swings back and forth horizontally through the connecting piece 15. A scraper 17 that cooperates with the cleaning of the hollow drum 2 is fixedly connected to the movable sleeve 16, and a scraper bar 18 that assists in cleaning the hollow drum 2 is fixedly connected to the bottom of the cylinder barrel 3. With the assistance of the scraper bar 18, the scraper 17 is driven by the swing arm 75 that swings back and forth horizontally through the connecting piece 15 and the movable sleeve 16 to dynamically scrape and clean the mud adhered to the hollow drum 2, thereby improving the cleanliness of the hollow drum 2 and the flatness of the ground.

[0048] The suction assembly further includes a driven gear 83 meshed inside the driving gear 82, and a cam 84 is fixedly connected to the top of the driven gear 83 through a fixing rod. The two belt pulleys 62 drive the driving gears 82 on the two differential gears 81 to rotate synchronously. The two driving gears 82 drive the cams 84 on the two driven gears 83 to rotate accordingly. A connecting rod 85 is hinged to the top of the cam 84, and a piston 86 slidably engaged with the cylinder barrel 3 is hinged to the inner side of the connecting rod 85. The two cams 84 drive the pistons 86 on the two connecting rods 85 to perform reciprocating work in the two cylinder barrels 3, and alternately generate positive and negative pressures in the two cylinder barrels 3, facilitating the subsequent regulation of the gravity of the hollow drum 2;

[0049] The regulation assembly further includes a supply and discharge pipe 93 connected to the inner end of the six-way valve 91. The outer end of the supply and discharge pipe 93 is connected to a three-way head 94. The outer end of the three-way head 94 is connected to a water storage tank 95 fixedly fitted with the fixing frame 4 and is provided with a second liquid level probe 21. A flow probe 96 is embedded in the outer end of the six-way valve 91. The outer end of the water distribution pipe rack 61 is connected to a communication port 19. The end of the suction pipe 92 is connected to a rotating port 20 rotatably engaged with the communication port 19 and they are kept in a communicating state with each other. Under the action of the alternately generated positive and negative pressures in the two cylinder barrels 3, the water filled in the hollow drum 2 is sucked under negative pressure through the two suction pipes 92 on the six-way valve 91, and then the sucked water is supplied into the two water storage tanks 95 through the three-way head 94 on the supply and discharge pipe 93 under the action of the positive pressure, reducing the overall gravity of the hollow drum 2. On the contrary, the water in the two water storage tanks 95 flows back into the hollow drum 2, increasing the overall gravity of the hollow drum 2, and performing adaptive rolling and leveling according to the ground material.

[0050] Such as Figure 14As shown, during the period when the hollow roller 2 rolls and flattens the loose soil ground, the loose soil ground is easy to raise dust, and it does not have the dynamic spray dust reduction function, which pollutes the on-site construction environment. Both sides of the bottom of the fixed frame 4 are provided with dust reduction components used in conjunction with the combing component and the regulating component, and the dust reduction component includes a pressurized pipe 101 connected to the outside of the water storage tank 95, and a booster valve is provided on the pressurized pipe 101. When it is necessary to carry out dust reduction treatment on the dust raised from the ground, the water in the two groups of water storage tanks 95 is first provided with a water source supply, and the two pressurized pipes 101 and the booster valve are used for pressurization treatment, and the outer end of the pressurized pipe 101 is connected to a threaded Hose 102, the end of the threaded hose 102 is connected to a U-shaped tube 103, and both ends of the U-shaped tube 103 are connected to a main pipe rack 104 fixedly matched with the skeleton 76. The water in the two groups of water storage tanks 95 is supplied into the two U-shaped tubes 103 through the two threaded hoses 102, and then supplied into the two main pipe racks 104 that follow the two groups of skeletons 76 to expand outward and return inward for reciprocating motion. The bottom end array of the main pipe rack 104 is connected to a booster nozzle 105. Finally, the water in the two groups of water storage tanks 95 is sprayed in a horizontal dynamic manner by the booster nozzles 105 distributed in two rows of arrays to reduce dust, thereby improving the environmental cleanliness of the ground leveling site.

[0051] The working principle of a ground leveling device for land reclamation is as follows: first, the pulling arm 5 is plugged into the traction equipment, and the hollow drum 2 is driven by the side cover 1 to roll and level the ground. The rotating hollow drum 2 drives two sets of pulleys 62 to rotate synchronously through two water pipe racks 61. The two sets of pulleys 62 drive the cross bars 64 on the two sets of synchronous wheels 63 to rotate through two synchronous belts. The cross bars 64 drive the sub-gears 66 on the main gear 65 to rotate successively. The sub-gears 66 drive the reciprocating screw 71 to rotate. The T-shaped slide groove 12 and the T-shaped slide bar 13 play a sliding limit role on the screw sleeve 72. The reciprocating screw 71 drives the two sets of rack plates 73 on the screw sleeve 72 to move back and forth horizontally. The two sets of rack plates 73 that move back and forth horizontally drive the swing arms 75 on the two sets of steering gears 74. The two sets of frames 76 are rotated alternately in the forward and reverse directions. With the T-shaped guide rail 14 and the T-shaped sliding mouth acting as sliding limiters for the convex head and the frame 76, the swing arms 75 rotating alternately in the forward and reverse directions drive the two sets of frames 76 to expand outwards and reset inwards for reciprocating motion. The two sets of frames 76 that are expanding outwards and reciprocating inwards clean and comb the debris such as stones and plants in front of the hollow drum 2 to the periphery of the flattened area by shifting the teeth. At the same time, the two sets of frames 76 drive the two sets of movable sleeves 16 to slide horizontally and reciprocatingly on the cross bar 64 through the two sets of connecting pieces 15. With the scraping strip 18 assisting in scraping the hollow drum 2, the two sets of movable sleeves 16 drive the two sets of scraping frames 17 to scrape and clean the mud impurities adhering to the hollow drum 2 in a horizontal reciprocating displacement manner, thereby ensuring the cleanliness of the hollow drum 2 and the flatness of the ground.

[0052] During the period when the weight of the hollow drum 2 needs to be reduced and regulated according to the current ground material, while the two cloth water pipe racks 61 drive the two sets of pulleys 62 to rotate synchronously, the two sets of pulleys 62 also drive the two sets of differential gears 81 to rotate synchronously. The two sets of differential gears 81 drive the driven gears 83 on the two sets of drive gears 82 to rotate successively. The two sets of driven gears 83 drive the pistons 86 on the two connecting rods 85 to reciprocate and do work in the two cylinder barrels 3. Under the electric regulation and cooperation of the six-way valve 91, when the two pistons 86 do negative-pressure work in the two cylinder barrels 3, the negative-pressure pressure generated in the two cylinder barrels 3 is conducted to the two suction pipes 92 through the six-way valve 91, and then conducted to the two cloth water pipe racks 61 through the communicating ports 19 and the rotating ports 20 that rotate and communicate with each other. Under the action of the negative-pressure force, the water in the hollow drum 2 is sucked by negative pressure. The sucked water reaches the supply and discharge pipe 93 through the six-way valve 91 along the original path, then reaches the two water storage tanks 95 through the three-way head 94, and the flow probe 96 and the first liquid level probe 11 monitor the water volume and liquid level sucked from the hollow drum 2 in real time. The second liquid level probe 21 monitors the water level in the two water storage tanks 95 in real time. After sucking the predetermined amount of water, the overall weight of the hollow drum 2 is reduced, which is suitable for rolling the ground with relatively soft soil. When it is necessary to increase the weight of the hollow drum 2, on the contrary, under the electric regulation and cooperation of the six-way valve 91, when the two pistons 86 do positive-pressure work in the two cylinder barrels 3, similarly, under the action of the positive-pressure force, the water in the two water storage tanks 95 is forced to be supplied into the two suction pipes 92 on the six-way valve 91 through the supply and discharge pipe 93, and then re-supplied into the hollow drum 2 until the preset gravity range in the hollow drum 2 is reached, and the weight increase regulation of the hollow drum 2 is completed, which is suitable for rolling the ground with relatively hard soil;

[0053] When the dust raised during the ground leveling by the hollow drum 2 is sprayed and dust-reduced, the water in the two water storage tanks 95 is first pressurized by the two pressure pipes 101 and the pressure-increasing valve, and then pressurized and supplied into the two U-shaped pipes 103 through the two threaded hoses 102. Then, the water in the two U-shaped pipes 103 is supplied into the main pipe rack 104 that swings reciprocally with the two frameworks 76, and finally, the raised dust is dynamically sprayed and dust-reduced in a horizontal swinging manner through the array-distributed pressure-increasing nozzles 105.
