[0018] The present invention will be further described in detail below with reference to the accompanying drawings.

[0019] like Figures 1-5 The following is an embodiment of the present invention, which discloses a soil improvement device based on high-standard farmland, including a support frame 1, which is fixed to the rear of a tractor. A rotary tiller 2 is fixedly connected to the support frame 1, and the rotary tiller 2's rotary teeth are used to break up soil clods in the soil for subsequent soil improvement treatment.

[0020] like Figure 1 , Figure 2 As shown, a receiving frame 3 is fixedly connected to the support frame 1, and the receiving frame 3 is located behind the rotary tiller 2. Two elongated storage boxes 4 are provided on the receiving frame 3, and the storage boxes 4 are used to store soil conditioner. At the same time, the two storage boxes 4 are parallel to each other, and the length direction of the two storage boxes 4 is perpendicular to the forward direction of the tractor.

[0021] like Figure 2 , Figure 3 As shown, each storage box 4 has a set of digging teeth 5 fixedly connected to its bottom. Each set of digging teeth 5 has multiple teeth, and the multiple teeth 5 are arranged at equal intervals along the length of the corresponding storage box 4. The bottom of the digging teeth 5 is inclined towards the rotary tiller 2, and the bottom end of the digging teeth 5 is flush with the bottom end of the rotary tiller blades of the rotary tiller 2. At the same time, a spreading hole 6 is provided through the bottom position of the digging teeth 5 on the side away from the rotary tiller 2, and the spreading hole 6 is connected to the corresponding storage box 4 so that the soil conditioner in the storage box 4 can be spread into the soil through the spreading hole 6.

[0022] The soil amendment device is propelled forward by a tractor. At this time, the rotary tiller 2 breaks up soil clods, while the digging teeth 5 excavate amendment trenches in the soil. The soil amendment agent in the storage tank 4 enters the amendment trenches through the spreading holes 6, allowing the agent to penetrate deeper into the soil for deeper amendment. Afterward, the soil is leveled and the amendment trenches are covered, thus completing the soil amendment operation.

[0023] like Figure 1 , Figure 3 As shown, the receiving frame 3 is provided with two elongated guide holes 7, and the two storage boxes 4 are slidably connected to the corresponding guide holes 7, with the sliding direction of the two storage boxes 4 being perpendicular to the forward direction of the tractor. Meanwhile, the receiving frame 3 is provided with a driving component 8, which is used to control the horizontal reciprocating motion of the two storage boxes 4.

[0024] like Figure 3 , Figure 4 As shown, the driving component 8 includes two driving blocks 81 respectively fixed to the corresponding storage boxes 4. A cylindrical driving column 82 is vertically fixedly connected to the center of the upper surface of each driving block 81. A forward / reverse motor 83 is disposed between the two storage boxes 4. The output shaft of the forward / reverse motor 83 is vertical, and the tail of the forward / reverse motor 83 is fixedly connected to the receiving frame 3. A driving rod 84 is horizontally fixedly connected to the top of the output shaft of the forward / reverse motor 83. Elongated driving grooves 85 are symmetrically arranged on both sides of the driving rod 84. The length direction of the driving grooves 85 is parallel to the axial direction of the driving rod 84, and the two driving columns 82 are slidably connected to the corresponding driving grooves 85.

[0025] The drive rod 84 is controlled to reciprocate by the forward and reverse motor 83. At this time, the two drive columns 82 reciprocate under the action of the inner side wall of the corresponding drive groove 85, and the two drive blocks 81 drive the corresponding storage box 4 to reciprocate, and the two storage boxes 4 move in opposite directions.

[0026] Because the two storage boxes 4 can reciprocate, the movement trajectory of the two rows of digging teeth 5 is a zigzag shape. Compared with the straight movement of the digging teeth 5, this design can increase the length of the movement trajectory of the digging teeth 5, allowing more soil conditioner to enter the soil and effectively improve the soil conditioning effect.

[0027] At the same time, the two storage boxes 4 move in opposite directions, meaning the soil conditioner's spray path is a double-zigzag shape, which effectively improves the uniformity of soil conditioner spraying and ensures that more soil conditioner enters the soil, thereby further improving the soil improvement effect.

[0028] Furthermore, after the excavating teeth 5 dig up the soil, the soil accumulates on both sides of the soil amendment trench. Due to the reciprocating motion of the two rows of excavating teeth 5, the excavated soil forms a zigzag pattern. This allows the excavated soil to be smoothly backfilled into the soil amendment trench during subsequent leveling, ensuring stable burial of the soil amendment. Simultaneously, because the two rows of excavating teeth 5 move in opposite directions, the soil excavated by the rear excavating teeth 5 can also be backfilled into the corresponding soil amendment trench by the front excavating teeth 5, thus achieving partial automatic backfilling and facilitating subsequent leveling operations.

[0029] like Figure 2 , Figure 3 As shown, two rows of elastic vibrating hammers 9 are hinged to the receiving frame 3. Multiple vibrating hammers 9 are arranged in each row, and each vibrating hammer 9 is located on the side of a corresponding storage box 4. The multiple vibrating hammers 9 are arranged sequentially along the sliding direction of the storage box 4. Each of the two storage boxes 4 is equipped with a pipe control device 10, which controls the sequential swinging of the corresponding row of vibrating hammers 9, causing them to strike the corresponding storage box 4 in sequence. This vibrates the soil conditioner inside the storage box 4, reducing the risk of blockage at the spreading hole 6 and ensuring the soil conditioner smoothly enters the soil.

[0030] like Figure 2 , Figure 5 As shown, the control device 10 includes a control rod 101 horizontally fixed to the storage box 4. The control rod 101 is conical, and the diameter of the end of the control rod 101 away from the storage box 4 is smaller than the diameter of the other end. When the storage box 4 reciprocates, the control rod 101 can sequentially actuate the hammer rod of the vibrating hammer 9, causing the hammer head of the vibrating hammer 9 to swing away from the storage box 4. At the same time, multiple control springs 102 are provided on the receiving frame 3. The control springs 102 are used to push the hammer rod of the vibrating hammer 9 to swing towards the storage box 4, and cause the hammer head of the vibrating hammer 9 to strike the storage box 4.

[0031] When the storage tank 4 reciprocates, the control lever 101 sequentially actuates the hammer rods of multiple vibrating hammers 9, causing the hammer heads of the vibrating hammers 9 to swing away from the storage tank 4. After the control lever 101 separates from the hammer rods of the vibrating hammers 9, the vibrating hammers 9, under their own weight and the action of the control spring 102, swing towards the storage tank 4, causing their hammer heads to strike the storage tank 4, thereby vibrating the soil conditioner inside the storage tank 4. This design allows the vibrating hammers 9 to automatically strike the storage tank 4 during its reciprocating motion, improving the linkage effect between components and eliminating the need for an additional drive source, thus improving the rational utilization of resources.

[0032] like Figure 1 , Figure 2As shown, a smoothing plate 11 is provided at the end of the receiving frame 3 away from the rotary tiller 2. The bottom of the smoothing plate 11 is inclined away from the rotary tiller 2, and the bottom end of the smoothing plate 11 is flush with the rotary tiller shaft of the rotary tiller 2, so that the smoothing plate 11 can automatically smooth the soil during the forward movement of the tractor, thereby improving the work efficiency.

[0033] like Figure 2 , Figure 3 As shown, multiple rows of soil-breaking rods 12 are vertically slidably connected on the support frame 1. The multiple rows of soil-breaking rods 12 are located in front of the rotary tiller 2. The multiple rows of soil-breaking rods 12 are parallel to each other, and adjacent rows of soil-breaking rods 12 are staggered. At the same time, a control component 13 is provided on the support frame 1. The control component 13 is used to control the alternating vertical movement of the multiple rows of soil-breaking rods 12.

[0034] The control unit 13 controls the alternating vertical movement of multiple rows of soil-breaking rods 12. The soil-breaking rods 12 can break up large soil clods in the soil, facilitating the subsequent soil-breaking operation of the rotary tiller 2. At the same time, the alternating movement of the multiple rows of soil-breaking rods 12 means that once a soil clod is lifted up by a soil-breaking rod 12 in one row, the soil-breaking rods 12 in the adjacent row can push the soil clod down as they move downwards, and break the soil clod again, ensuring the soil-breaking effect.

[0035] like Figure 2 , Figure 3 As shown, the control component 13 includes multiple hydraulic cylinders 131 that are respectively fixed on the support frame 1. Each hydraulic cylinder 131 has a control rod 132 fixedly connected to its piston end. The top of each row of soil-breaking rods 12 is fixedly connected to the corresponding control rod 132. Adjacent hydraulic cylinders 131 work alternately, that is, adjacent hydraulic cylinders 131 perform extension and retraction movements in sequence.

[0036] This embodiment also discloses a soil improvement method using the aforementioned soil improvement device, comprising the following steps: S1, Land leveling project: The land is surveyed and marked out, and the surface trees and weeds are cleared. Then, the topsoil is stripped off using a bulldozer, with the stripping depth controlled at 20-30cm. After that, the subsoil is leveled and the topsoil is backfilled.

[0037] S2, Soil Improvement Project: Large clods of soil in the backfilled topsoil are broken up by the soil breaking rod 12 in the soil amendment device, and then the soil is tilled by the rotary tiller 2. At the same time, the digging teeth 5 dig up the soil and allow the soil amendment in the storage box 4 to enter the soil. Subsequently, the smoothing plate 11 smooths the soil and covers the soil amendment with soil, thereby achieving deep soil amendment.

[0038] S3, Field Road Engineering; The land is surveyed for road layout, and a foundation pit is excavated based on the survey results. The foundation pit is then filled with gravel and compacted. A row of curb stones is buried on both sides of the foundation pit, and concrete is poured between the two rows of curb stones. After the concrete has cured and formed a concrete pavement, the concrete pavement is covered with geotextile for curing. After the concrete pavement has cured, the geotextile is removed, thus realizing the construction of the field road.

[0039] The specific embodiments are merely illustrative of the present invention and are not intended to limit the invention. After reading this specification, those skilled in the art can make modifications to these embodiments without contributing any inventive step, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
