[0063] See also Figures 1 to 9 In an embodiment of the present invention, a leveling device for land management includes:

[0064] The main body 1 of the device is provided with moving wheels on four sides;

[0065] The earth-breaking device 2 is fixed to the front end of the equipment body 1 and connected to the tractor;

[0066] A crushing roller 3 is rotatably arranged in the equipment body 1 and adjacent to the earth-breaking device 2;

[0067] The treatment mixing device 4 is fixed in the middle of the equipment body 1;

[0068] The impurity removal device 5 is fixed to the end of the equipment body 1 away from the crushing roller 3;

[0069] The leveling device 6 is fixed at the rear end of the equipment body 1 .

[0070] In this embodiment, the earth-breaking device 2 includes:

[0071] A traction frame 21, fixedly connecting the equipment body 1 and the tractor;

[0072] The earth-breaking blades 22 are arranged in a plurality of groups in a straight line, and each group is provided with a plurality of earth-breaking blades, which are fixed on the traction frame 21 , and the two groups of earth-breaking blades 22 are staggered.

[0073] That is to say, driven by the tractor, the equipment body 1 moves on the land and drives the breaking shovel 22 to cut into the soil to break the land. The staggered design of the breaking shovel 22 makes the soil resistance dispersed periodically, avoiding a single set of shovels from continuously bearing high loads, reducing traction resistance, and reducing energy consumption. At the same time, the crushing roller 3 is started, and the large pieces of soil are turned over by the breaking shovel 22, and are then drawn in and crushed by the crushing roller 3, so that the particle size of the soil blocks is uniform, so as to facilitate soil management.

[0074] In this embodiment, the treatment mixing device 4 includes:

[0075] A positioning frame 41 is fixed to the lower bottom surface of the top plane of the device body 1;

[0076] The connecting mechanism 42 is provided in the middle of the positioning frame 41 and is fixedly connected to the device body 1;

[0077] The rotating assembly 43 is symmetrically distributed with two groups about the connecting mechanism 42 and is rotatably arranged on the positioning frame 41;

[0078] The telescopic spray assembly 44 is composed of a telescopic adjustment shaft 441 and a spray head 442. The telescopic adjustment shaft 441 is rotatably connected to the rotating assembly 43, the fixed end is fixedly connected to the device body 1, and the extended end passes through the positioning frame 41 and is fixedly connected to the spray head 442;

[0079] The center of the top of the mixing assembly 45 is rotatably connected to the telescopic spray assembly 44, and the outer side of the top is fixedly connected to the rotating assembly 43 through a telescopic shaft.

[0080] That is to say, after the soil is turned over and crushed, the telescopic spray assembly 44 drives the mixing assembly 45 to move downward, so that the mixing assembly 45 contacts the soil, and driven by the rotating assembly 43, the mixing assembly 45 rotates in the soil, and at the same time, the spray head 442 sprays out the soil conditioner. Under the continuous rotation of the mixing assembly 45, the soil conditioner and the soil are fully mixed to treat the soil.

[0081] In this embodiment, the connecting mechanism 42 includes:

[0082] The fixed column 421 is fixedly connected to the top plane of the device body 1;

[0083] Two connecting shafts 422 are symmetrically distributed and fixed to the bottom of the fixed column 421;

[0084] The transmission gear 423 is rotatably disposed at the bottom of the connecting shaft 422 , and the transmission gears 423 are meshed with each other and respectively connected to the rotating components 43 on both sides.

[0085] That is, under the transmission action of the transmission gear 423, the adjacent rotating components 43 rotate in the opposite direction, thereby driving the corresponding mixing components 45 to rotate in the opposite direction, mixing and stirring the soil, so that the soil and the improver are fully mixed to treat the soil.

[0086] As a preferred embodiment, the treatment mixing device 4 is provided with multiple groups in parallel, and the mixing components 45 between each group are staggered to ensure that the mixing components 45 fully mix the soil, so that the soil conditioner is fully mixed into the soil and the land properties are improved.

[0087] In this embodiment, the rotating assembly 43 includes:

[0088] The rotating motor 431 is fixed to the side of the positioning frame 41, and a bevel gear is provided on the shaft of the rotating motor 431;

[0089] The transmission bevel gear 432 is rotatably mounted on the telescopic spray assembly 44 and meshes with the bevel gear on the rotating motor 431;

[0090] The rotating gear 433 is fixed to the lower part of the transmission bevel gear 432 and connected to the connecting mechanism 42;

[0091] The connecting surface 434 is fixed to the lower portion of the rotating gear 433 and is located below the positioning frame 41 , and is fixedly connected to the mixing assembly 45 via a telescopic shaft.

[0092] That is to say, driven by the rotating motor 431, the rotating gear 433 and the connecting surface 434 are driven to rotate through the transmission bevel gear 432. The rotating gear 433 drives the other rotating component 43 to rotate in the opposite direction under the transmission of the connecting mechanism 42, and under the action of the connecting mechanism 42, a certain distance is ensured between the rotating components 43 on both sides, so that the two groups of mixing components 45 can work normally. The connecting surface 434 drives the mixing component 45 to rotate on the telescopic spray component 44 to mix the soil and the amendment. When the telescopic adjustment shaft 441 is extended, the mixing component 45 moves down at the bottom of the connecting surface 434. When the telescopic adjustment shaft 441 is contracted, the mixing component 45 moves up at the bottom of the connecting surface 434 to adjust the depth of the mixing component 45 entering the soil to ensure that the amendment enters the soil and transforms the land.

[0093] In this embodiment, the mixing assembly 45 includes:

[0094] The limiting frame 451 is rotatably connected to the lower part of the telescopic spray assembly 44 in the middle, and fixedly connected to the bottom of the rotating assembly 43 on the outer side via a telescopic shaft;

[0095] The adjusting units 452 are provided in a plurality in an annular arrangement and are fixed to the limiting frame 451 . Two adjacent adjusting units 452 are connected via a universal joint 453 , wherein a driving motor is provided between the two adjacent adjusting units 452 .

[0096] That is to say, under the action of the limiting frame 451, the mixing assembly 45 rotates at the lower part of the telescopic spray assembly 44, and then when the rotating assembly 43 drives the mixing assembly 45 to rotate, the telescopic spray assembly 44 remains fixed, and when the telescopic spray assembly 44 drives the mixing assembly 45 to move up and down for adjustment, the limiting frame 451 adjusts the distance between the mixing assembly 45 and the connecting surface 434 through the telescopic shaft, and multiple adjustment units 452 are synchronously adjusted through the universal joint 453 during the rotation of the mixing assembly 45 to fully mix the soil and the amendment.

[0097] In this embodiment, the adjustment unit 452 includes:

[0098] The limiting frame 4521 is fixed to the inner ring of the limiting frame 451;

[0099] The adjustment frame 4522 is fixed to the outer ring of the limiting frame 451 and corresponds to the limiting frame 4521;

[0100] The adjusting gear 4523 is rotatably mounted in the adjusting frame 4522 and fixedly connected to the universal joint 453 on both sides;

[0101] The adjusting rack 4524 is slidably disposed within the adjusting frame 4522 and the limiting frame 4521 and is connected to the adjusting gear 4523;

[0102] The mixing rod 4525 is vertically fixed to one end of the adjusting rack 4524 close to the limiting frame 4521.

[0103] That is to say, under the action of the driving motor, the adjusting gear 4523 is driven to rotate synchronously through multiple universal joints 453, and under the action of the limit frame 4521 and the adjustment frame 4522, the adjusting rack 4524 is driven to move synchronously at the same time, thereby driving the mixing rod 4525 to move toward the center or outside of the limit frame 451, and dynamically adjusting the position of the mixing rod 4525. Under the adjustment action of the telescopic adjustment shaft 441 in the telescopic spray assembly 44, the improver and the soil are fully contacted through the three-dimensional motion trajectory, thereby improving the mixing efficiency.

[0104] In this embodiment, the impurity removal device 5 includes:

[0105] A fixed shaft 51 is fixed in the device body 1;

[0106] The cleaning rakes 53 are symmetrically distributed with two groups about the center of the fixed shaft 51, are tilted, fixedly connected to the fixed shaft 51, and are provided with a dispersion column 52 in the middle;

[0107] A guide rake 54 is fixed to the side of the cleaning rake 53 away from the dispersion column 52;

[0108] The collecting box 55 connects the guide rake 54 and the equipment body 1 .

[0109] That is to say, the mixed soil is dispersed to both sides under the action of the dispersion column 52, and the inclined cleaning rake 53 combs the soil when the equipment moves. The impurities move backward along the cleaning rake 53 and move to the collection box 55 through the guide rake 54. The impurities are automatically separated, reducing the need for manual inspection.

[0110] In this embodiment, the leveling device 6 includes:

[0111] The carrier 61 is fixed to the rear end of the device body 1;

[0112] The power motor 62 is fixed on the carrier 61 and connected to the driving shaft 63;

[0113] There are two symmetrically distributed rotating flat members 64, which are connected to the driving shaft 63 through a bevel gear set;

[0114] The reciprocating mechanism 65 is fixed on the driving shaft 63 and is connected to a pressure leveling component 66 on the top.

[0115] That is to say, the power motor 62 drives the bevel gear set to make the two rotating leveling members 64 rotate in opposite directions to initially level the soil, and under the action of the driving shaft 63, it drives the reciprocating mechanism 65 to perform reciprocating motion, driving the pressure leveling component 66 to apply periodic pressure to the soil to eliminate small fluctuations.

[0116] In this embodiment, the pressure leveling assembly 66 includes:

[0117] Two positioning members 661 are symmetrically arranged and fixed on the carrier 61;

[0118] The shaft 662 is fixedly connected to the positioning members 661 on both sides;

[0119] The telescopic plate 663 is rotatably mounted on the shaft 662 , with its protruding end fixed to the top of the reciprocating mechanism 65 and the other end fixedly connected to the pressing plate 664 .

[0120] That is to say, when the rotating leveling member 64 initially levels the soil, it simultaneously drives the reciprocating mechanism 65 to drive the telescopic plate 663 to reciprocate up and down through the cam mechanism, and the pressure plate 664 applies periodic pressure to the soil to eliminate small fluctuations to achieve the purpose of leveling the land.

[0121] During the specific implementation, first, the main body 1 of the equipment moves on the land under the drive of the tractor, and drives the soil-breaking shovel 22 to cut into the soil to break the soil. At the same time, the crushing roller 3 is started, and the large pieces of soil are turned over by the soil-breaking shovel 22, and are then drawn in and crushed by the crushing roller 3 to make the particle size of the soil clods uniform. Then, while the main body 1 of the equipment continues to move, the rotating component 43 drives the mixing component 45 to rotate through the connecting mechanism 42, and under the action of the telescopic adjustment shaft 441, the height of the mixing component 45 is adjusted so that the mixing rod 4525 of the mixing component 45 penetrates into the soil. Driven by the rotating component 43, the mixing rod 4525 rotates in the soil, and the spray head 442 continuously sprays the soil conditioner. At the same time, under the action of the driving motor, the position of the mixing rod 4525 is adjusted by adjusting the rack 4524 to form a three-dimensional mixing trajectory, so that the improver and the soil are in full contact, and the mixing efficiency is improved. Then, the inclined cleaning rake 53 combs the soil when the equipment moves, and the impurities move backward along the cleaning rake 53 and move to the collection box 55 through the guide rake 54. The impurities are automatically separated, and then the power motor 62 drives the bevel gear set to make the two rotating leveling parts 64 rotate in opposite directions to preliminarily scrape the soil flat. Under the action of the driving shaft 63, the reciprocating mechanism 65 is driven to perform reciprocating motion, driving the pressure leveling component 66 to apply periodic pressure to the soil, eliminating small fluctuations, and completing the land management and leveling work.
