[0039] The following combination Figures 1-14The movable field land construction leveling device of the present invention comprises: an external connecting frame 100, a counterweight leveling frame 110 and a leveling tooth comb 111, the upper end of the external connecting frame 100 is installed with a driving motor 200, the counterweight leveling frame 110 is hinged to one side of the external connecting frame 100, and the leveling tooth comb 111 is fixedly connected to the lower end of the counterweight leveling frame 110; a leveling mechanism 300, the leveling mechanism 300 is installed inside the external connecting frame 100, the leveling mechanism 300 is connected to the surface of the driving motor 200, and the surface of the leveling mechanism 300 extends to the counterweight leveling frame 110. The inner side of the smoothing frame 110; wherein the leveling mechanism 300 includes a crushing assembly 310, a soil turning assembly 320 and a leveling assembly 330, the crushing assembly 310 is installed on the inner side of the external connecting frame 100, the soil turning assembly 320 is installed on the inner side of the external connecting frame 100, the surface of the crushing assembly 310 is connected to the soil turning assembly 320, the crushing assembly 310 is installed on the surface of the driving motor 200, the leveling assembly 330 is installed on the side of the crushing assembly 310 away from the soil turning assembly 320, and the surface of the leveling assembly 330 extends to the inner side of the counterweight smoothing frame 110;

[0040] like Figure 1 、 Figure 2 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 、 Figure 11 As shown, the crushing assembly 310 includes a rotating shaft 311, a soil storage and crushing bin 312, two sets of inclined group plates 313, a auger plate 314, and two first pulleys 315. The rotating shaft 311 is rotatably connected to the inner wall of the drive motor 200, the soil storage and crushing bin 312 is fixedly connected to the inner wall of the external connecting frame 100, the two sets of inclined group plates 313 are fixedly connected to the inner wall of the soil storage and crushing bin 312, both ends of the rotating shaft 311 pass through the outside of the external connecting frame 100, the first pulley 315 is fixedly connected to the end of the rotating shaft 311, and the auger plate 314 is fixedly connected to the inner wall of the driving motor 200. 4 is fixedly connected to the surface of the rotating shaft 311. A plurality of discharge holes 317 are formed on the surface of the soil storage and crushing chamber 312. The discharge holes 317 are connected to the interior of the soil storage and crushing chamber 312. The inclined plate group 313 is formed by a plurality of curved plates. The curved plates form an acute angle with the vertical inner wall of the external connecting frame 100. The inner curved surface of the curved plates is eccentrically arranged with the central axis of rotation of the rotating shaft 311. The outer edge of the auger plate 314 is fixedly connected to the crushing teeth 316. The crushing teeth 316 are offset toward the driving motor 200 away from the end of the auger plate 314.

[0041] When the device is in use, the driving motor 200 is started to drive the rotating shaft 311 to rotate, and the auger plate 314 is rotated inside the soil storage and crushing bin 312. When a large soil block enters the soil storage and crushing bin 312, the inclined group plate 313 on the inner wall of the soil storage and crushing bin 312 forms an auxiliary positioning effect. At this time, when the auger plate 314 rotates, the auger plate 314 is close to the inclined group plate 313 and the inclined direction of the inclined group plate 313 is opposite to that of the inclined group plate 313, which forms a shearing effect on the soil block, thereby crushing the soil block. At the same time, the crushing teeth 316 are offset and tilted toward the driving motor 200, which can assist in crushing the soil block, and the crushed soil block is discharged to the outside through the discharge hole 317.

[0042] When the soil block enters the soil storage and crushing bin 312, the soil block is located between the inclined group plate 313 and the auger plate 314. As the auger plate 314 drives the crushing teeth 316 to rotate, the soil block gradually moves toward the smoothing comb 111 as the auger plate 314 rotates. At this time, the distance between the auger plate 314 and the inclined group plate 313 gradually shortens, which will gradually crush the soil block into smaller pieces.

[0043] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 12 As shown, the soil turning assembly 320 includes a guide inclined plate 321 and a soil breaking and turning head 322. The guide inclined plate 321 is fixedly connected to the lower end of the external connecting frame 100. The soil breaking and turning head 322 is fixedly connected to the arc surface of the lower end of the guide inclined plate 321. The soil breaking and turning head 322 is fixedly connected to the lower end of the soil storage crushing bin 312. The width of the end of the soil breaking and turning head 322 away from the soil turning assembly 320 is smaller than the width of the other end of the soil breaking and turning head 322. A soil separation groove 327 is provided at the lower end of the soil breaking and turning head 322. A soil inlet 328 is provided inside the soil breaking and turning head 322. The soil inlet 328 is connected to the discharge hole 317. The soil turning assembly 320 also includes a rotating horizontal shaft 323 rotatably connected to the inner wall of the external connecting frame 100. A plurality of shifting rubber plates 324 are fixedly connected to the surface of the rotating horizontal shaft 323. The surface of the shifting rubber plates 324 contacts the upper end arc surface of the guide inclined plate 321. The plurality of shifting rubber plates 324 are staggered along the surface of the rotating horizontal shaft 323. One end of the rotating horizontal shaft 323 passes through the outside of the external connecting frame 100 and is fixedly connected to a second pulley 325. The inner side of the second pulley 325 is provided with a first transmission belt 326. The first transmission belt 326 is sleeved on the surface of the adjacent first pulley 315.

[0044] The tip of the soil breaking and turning head 322 is inserted into the soil layer, thereby crushing and turning the soil. At the same time, the side surfaces of the adjacent soil breaking and turning heads 322 form a gathering effect on the turned soil, and the refined soil is gathered through the gradually narrowing gap between the two soil breaking and turning heads 322. At the same time, large pieces of soil are turned and lifted by the tip of the soil breaking and turning head 322 and are moved by the moving rubber plate 324 to the upper end of the guide inclined plate 321. Along with the curved surface of the guide inclined plate 321, the soil pieces enter the interior of the soil crushing bin 312. As the first pulley 315 rotates, it drives the first transmission belt 326 to rotate accordingly. At this time, the first pulley 315 and the second pulley 325 are connected by the first transmission belt 326, so that the second pulley 325 drives the moving rubber plate 324 to rotate through the rotating horizontal shaft 323, so that the moving rubber plate 324 moves the large soil pieces along the curved surface of the guide inclined plate 321 into the soil crushing bin 312.

[0045] The crushed soil inside the soil storage and crushing bin 312 enters the soil inlet 328 through the discharge hole 317 and falls into the soil separation trough 327 under the action of gravity, so that the refined soil first fills the gullies created by the soil breaking and turning head 322 plowing the land. After the initial filling, the gaps between the refined soil are larger, and the land becomes loose and convenient for land leveling operations.

[0046] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 12 、 Figure 13 、 Figure 14 As shown, the leveling assembly 330 includes a connecting rod 331, an electric push rod 332, a collar 333 and a spline shaft 334. The connecting rod 331 is fixedly connected to the inner wall of the external connecting frame 100. The two ends of the external connecting frame 100 are respectively hinged with hinge plates. The spline shaft 334 is rotatably connected to the inner wall of the hinge plate. The electric push rod 332 is rotatably connected to the surface of the connecting rod 331. The collar 333 is rotatably connected to the telescopic end of the electric push rod 332. The spline shaft 334 is connected to the inner wall of the collar 333. The spline shaft 334 The surface of the spline shaft 334 is fixedly connected to a plurality of fixed sleeves 337, the surface of the fixed sleeve 337 is fixedly connected to a plurality of connecting rods 338, the other end of the connecting rod 338 is fixedly connected to a deflector plate 339, and the plurality of deflector plates 339 are distributed in a ring shape along the surface of the fixed sleeve 337, and the adjacent deflector plates 339 are inclined in opposite directions. One end of the spline shaft 334 is fixedly connected to a third pulley 335, and the surface of the third pulley 335 is sleeved with a second transmission belt 336, and the second transmission belt 336 is sleeved on the surface of the adjacent crushing assembly 310;

[0047] The first pulley 315 rotates along with the rotating shaft 311 and drives the third pulley 335 to rotate along with it through the second transmission belt 336, thereby causing the spline shaft 334 to rotate synchronously. The rotation of the spline shaft 334 drives multiple fixed sleeves 337 to rotate synchronously, thereby forming a connecting rod 338 to drive the soil-splitting plate 339 to disperse the soil to both sides. At this time, the soil in the soil is staggered and separated to both sides by the soil-splitting plate 339, so that the soil gullies and the height of the soil tend to be flat. By driving the electric push rod 332, the spline shaft 334 is driven to rotate synchronously. 34 moves, wherein the spline shaft 334 moves in an arc along the hinge plate, thereby adjusting the level of the land leveling. Afterwards, the external connecting frame 100 drives the counterweight leveling frame 110 to level the ground, and the sparse and broken soil is evenly separated by the leveling comb 111, and the remaining small soil blocks are evenly leaked through the tooth grooves of the leveling comb 111, so that the land forms an overall leveling effect. The counterweight leveling frame 110 can also be equipped with leveling components such as round rollers to assist in the leveling operation. Appropriate tools are added according to actual conditions.

[0048] During use, the traction vehicle drives the external connecting frame 100 to move, wherein the driving motor 200 is started to drive the rotating shaft 311 to rotate, and the auger plate 314 rotates inside the soil crushing bin 312. When the rotating shaft 311 rotates, it will drive the first pulleys 315 at both ends to follow and rotate synchronously. At this time, the first pulley 315 is connected to the second pulley 325 through the first transmission belt 326, and the second pulley 325 is driven by the rotating horizontal shaft 323. The rubber plate 324 is moved to rotate, and the rubber plate 324 moves large soil blocks along the curved surface of the guide inclined plate 321 into the soil storage crushing bin 312. The tip of the soil breaking and turning head 322 crushes the soil. The space between the two adjacent soil breaking and turning heads 322 gradually narrows and crushes the soil to form a soil cluster. The large soil blocks are turned and lifted by the tip of the soil breaking and turning head 322. The rubber plate 324 is moved to move the soil blocks along the curved surface of the guide inclined plate 321 into the soil storage crushing bin 312; the larger soil blocks enter the soil storage crushing bin 312. When the auger plate 314 rotates, it cooperates with the inclined group plate 313 to shear and crush the soil blocks. The soil blocks are located between the inclined group plate 313 and the auger plate 314. As the auger plate 314 drives the crushing teeth 316 to rotate, the soil blocks gradually move toward the smoothing comb 111 as the auger plate 314 rotates. The distance between the auger plate 314 and the inclined group plate 313 is gradually shortened, which will gradually crush and refine the soil blocks. The crushing teeth 316 deviate toward the direction of the drive motor 200 to tilt and squeeze the soil blocks to assist The broken soil is discharged to the outside through the discharge hole 317; the first pulley 315 drives the third pulley 335 to rotate with it through the second transmission belt 336, and the spline shaft 334 drives multiple fixed sleeves 337 to rotate synchronously, so that the connecting rod 338 drives the soil-moving plate 339 to move the soil to both sides, and the external connecting frame 100 drives the counterweight leveling frame 110 to level the ground. The small soil blocks are evenly discharged through the tooth grooves of the smoothing comb 111, and the land forms an overall leveling effect.
