Description

Technical Field

[0001] The present invention relates to the technical field of soil remediation and treatment, and more specifically, to a method for remediating and treating desertified soil. Background Art

[0002] Land desertification simply refers to land degradation, also known as "desertification", which is the land degradation in arid, semi-arid and dry sub-humid areas caused by various factors including climate variation and human activities, resulting in an environmental change process where areas that were not originally deserts exhibit desert-like landscapes. Therefore, sand prevention and fixation, as well as soil quality improvement, have become the top priorities.

[0003] Among them, small-grid shelterbelts refer to fixing sand and weakening wind erosion by tying sand willows or wheat straw grids in the desert. Currently, the operation of tying wheat straw grids is usually completed manually. That is, first, the wheat straw is spread flat on the desert, and then a shovel is used to press down the wheat straw so that the middle part of the wheat straw penetrates into the desert to achieve the purpose of sand fixation. However, manual operation is not only inefficient but also requires manual pre-placement of the wheat straw. After the wheat straw is placed, if it is not inserted in time, the wheat straw is easily blown over by the wind, resulting in ineffective placement and very inconvenient operation.

[0004] For example, in the patent document with the publication number CN113062294B, a new type of desertified soil treatment device uses a storage box to store wheat straw to be used, a feeding component to orderly feed the wheat straw in the storage box so that it is evenly spread and placed on the surface of the desert soil, and a deep insertion component to deeply insert the wheat straw spread on the sandy soil surface into the sandy soil;

[0005] However, when the wheat straw in the storage box is almost used up, since the wheat straw is a light and loose material with poor fluidity, especially when the remaining amount in the storage box is small, the upper wheat straw is easily blocked by the inclination angle of the guide plate or the surface friction due to the lack of gravity extrusion, forming local accumulation, which greatly affects the original laying progress. Therefore, a solution is provided herein. Summary of the Invention

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a method for remediating and treating desertified soil.

[0007] To achieve the above object, the present invention provides the following technical solution: A method for remediating and treating desertified soil, comprising the following steps:

[0008] Step 1: Put wheat straw into the storage box in the laying device, and adjust the distance between the two pressure rollers and the two storage boxes to determine the size of the wheat straw grid to be laid;

[0009] Step 2: Control the rotation of Motor 1, and the two lower feed gears rotate synchronously to feed and lay the wheat straw inside the two storage bins. The laid wheat straw is laid through the pressure roller behind the storage bin;

[0010] Step 3: When the amount of wheat straw inside the storage bin is not much, control the extension of the extending end of the cylinder, and the middle guide plate and the side guide plate rotate and move upward synchronously, increasing the inclination angle of both. And the two eccentric wheels drive the side guide plate to vibrate slightly, thereby vibrating the wheat straw piled up above the middle guide plate and the side guide plate. When the cylinder resets, vibrate the two again to complete the preliminary treatment and restoration of the soil in the set area.

[0011] Among them, a method for repairing and treating desertified soil is realized by relying on a laying device. The laying device includes two storage bins. A bottom connecting frame is arranged at the bottom of the storage bin. A feeding port is opened on the bottom side wall of the storage bin. A lower feed gear for blocking it is arranged inside the feeding port. It is characterized in that a guiding and feeding component for guiding the wheat straw is arranged inside the storage bin.

[0012] Further, the guiding and feeding component includes arc-shaped chutes symmetrically opened on the inner walls on both sides of the storage bin. An arc-shaped toothed plate is fixedly arranged on the bottom wall of the arc-shaped chute. A driving gear is meshed and connected to the bottom of the arc-shaped toothed plate.

[0013] Further, a connecting shaft is fixedly arranged between the two driving gears. A limiting plate is rotatably arranged in the middle of the connecting shaft through a bearing. A middle guide plate is fixedly arranged above the limiting plate. Eccentric wheels are symmetrically and fixedly arranged on both sides of the connecting shaft. A side guide plate is arranged above the eccentric wheel, and the lower part of the limiting plate is in contact with the side guide plate.

[0014] Further, the middle guide plate corresponds to the side guide plate. The ends of the middle guide plate and the side guide plate are rotatably connected to the bottom wall of the storage bin through pins. The bottoms of the middle guide plate and the side guide plate correspond to the feeding port. The bottom of the middle guide plate is rotationally matched with the bottom wall of the storage bin through a cylinder.

[0015] Further, two bidirectional threaded rods are also rotatably arranged between the bottom connecting frames. The ends of the bidirectional threaded rods are provided with Motor 2, and Motor 2 is connected to the bottom connecting frame. Fixed blocks are threadedly connected to the outer walls on both sides of the bidirectional threaded rod. The fixed block is fixedly connected to the corresponding storage bin.

[0016] Further, a driving shaft 1 is fixedly arranged inside one of the lower feed gears. The end of the driving shaft 1 passes through the storage bin and is provided with Motor 1. A driving shaft 2 is arranged inside the other lower feed gear, and the end of the driving shaft 2 is rotatably connected to the bottom connecting frame. A spline shaft 2 is slidably arranged between the two lower feed gears.

[0017] Further, a fixed shaft is rotatably arranged at the bottom of the storage box. Pressing rollers are fixedly arranged on the outer walls on both sides of the fixed shaft through bolts. A spline shaft I is slidably arranged between the two fixed shafts. The second driving shaft is connected to one of the fixed shafts through a transmission member.

[0018] Further, T-shaped plates are fixedly arranged on both sides of the storage box. A limiting long plate is slidably arranged between two groups of T-shaped plates on the same side. The bottom of the limiting long plate is fixedly connected to the bottom connecting frame through a side connecting plate.

[0019] The technical effects and advantages of the present invention are as follows:

[0020] 1. When adjusting the distance between the two pressing rollers in the present invention, first release the limit on the pressing rollers through bolts, then adjust the positions of the two pressing rollers above the fixed shaft according to requirements, and then fix them through bolts. Control the two groups of second motors to rotate simultaneously, the bidirectional threaded rod rotates synchronously, driving the two storage boxes to move closer together. When moving closer, they are limited by the T-shaped blocks and the limiting long plates, so as to complete the adjustment of the distance between the two pressing rollers. It can not only adjust the size of the squares, but also adjust the distance between the two storage boxes, and then quickly complete the laying of multiple groups of squares.

[0021] 2. When the amount of wheat straw in the storage box is not much in the present invention, control the extension end of the air cylinder to extend, the middle guide plate and the side guide plates rotate and move upward synchronously, increasing the inclination angles of the middle guide plate and the side guide plates. And the driving gear is meshed with the arc-shaped tooth plate, driving the driving gear to rotate. When the driving gear rotates, it drives the connecting shaft to rotate. When the connecting shaft rotates, it drives the two groups of eccentric wheels to rotate. The two groups of eccentric wheels drive the side guide plates to vibrate slightly, and then shake off the accumulated wheat straw above the middle guide plate and the side guide plates. When the air cylinder resets, vibrate the middle guide plate and the side guide plates again to completely shake off the wheat straw above them, avoiding local accumulation of wheat straw and thus affecting the original laying progress.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] Example 1: Please refer to Figures 1 - 7 As shown, the problem that the upper wheat straw in the prior art lacks gravity compression and is easily hindered by the inclination angle of the guide plate or the surface friction, forming local accumulation, which greatly affects the established paving progress, can be solved by the following solution;

[0032] In this embodiment, a method for repairing and treating desertified soil is implemented by a laying device, which includes two groups of storage boxes 1.

[0033] It should be noted that: the device is provided with a roller for pressing the straw grid, but it is a prior art and is not shown in the figure;

[0034] The guiding and dropping assembly 5 includes arc-shaped sliding grooves 52 symmetrically formed on the inner walls of both sides of the storage box 1.

The bottom of the middle guiding plate 59 is rotationally matched with the bottom wall of the storage box 1 through a cylinder 58. The limiting plate 56 is in contact with the lower part of the side guiding plates 51.

[0036] By controlling the extension of the extending end of the cylinder 58, the middle guiding plate 59 and the side guiding plates 51 rotate and move upward synchronously, increasing the inclination angles of the middle guiding plate 59 and the side guiding plates 51.

The other end of the second spline shaft 9 passes through the storage box 1 and is slidably matched with the center of the other lower shifting gear 6.

[0040] The two motors 13 are controlled to rotate simultaneously, and the bidirectional threaded rods 11 rotate synchronously, driving the two storage boxes 1 to move together synchronously, and when moving together, they are limited by the T-shaped block and the limiting long plate 19;

[0043] When adjusting the distance between the two pressing rollers 15, first release the limit of the pressing rollers 15 by bolts, then adjust the positions of the two pressing rollers 15 above the fixed shaft 14 according to needs, and then fix them by bolts;

[0044] Not only can the size of the grid be adjusted, but also the distance between the two storage boxes 1 can be adjusted, thereby quickly completing the laying of multiple groups of grids;

[0045] The second driving shaft 10 is connected to the other fixed shaft 14 via a transmission member 16;

[0047] See also Figures 1 - 6 As shown, T-shaped plates 18 are fixedly provided on both sides of the storage box 1, and a limiting long plate 19 is slidably provided between the two groups of T-shaped plates 18 on the same side.

[0048] Working principle:

[0049] Step 1: The device is driven to move by an external driving device. Before the wheat straw grid is formed, the wheat straw to be used is placed in the storage box 1 so that the length direction of the wheat straw is parallel to the feed opening 20 of the storage box 1. In the initial state, the lower gear 6 is in a blocking state to block the feed opening 20;

[0050] Then, the operator adjusts the distance between the two pressure rollers 15 according to the length of the wheat straw: when adjusting the distance between the two pressure rollers 15, first release the limit on the pressure roller 15 through bolts, then adjust the positions of the two pressure rollers 15 above the fixed shaft 14 according to requirements, and then fix them through bolts. At the same time, control the two groups of motors two 13 to rotate simultaneously, the bidirectional threaded rod 11 rotates synchronously, driving the two storage bins 1 to approach each other simultaneously, and when approaching, they are limited by the T-shaped block and the limit long plate 19, so as to complete the adjustment of the distance between the two pressure rollers 15; not only can the size of the square grid be adjusted, but also the distance between the two storage bins 1 can be adjusted, and then the laying of multiple groups of square grids can be quickly completed;

[0051] Step two: Control the motor one 8 to rotate, and synchronously drive the drive shaft one 7 and the drive shaft two 10 to rotate through the spline shaft two 9. Then, the two groups of lower feeding gears 6 can rotate synchronously to feed and lay the wheat straw inside the two storage bins 1. The laid wheat straw is laid through the pressure roller 15 behind the storage bin 1;

[0052] Step three: When the amount of wheat straw in the storage bin 1 is not much, control the extending end of the cylinder 58 to extend, and the middle guide plate 59 and the side guide plate 51 rotate and move upward synchronously, increasing the inclination angles of the middle guide plate 59 and the side guide plate 51. During this process, the driving gear 54 is meshed and connected with the arc-shaped toothed plate 53, driving the driving gear 54 to rotate. When the driving gear 54 rotates, it drives the connecting shaft 57 to rotate. When the connecting shaft 57 rotates, it drives the two groups of eccentric wheels 55 to rotate. The two groups of eccentric wheels 55 drive the side guide plate 51 to vibrate slightly, and then shake off the accumulated wheat straw above the middle guide plate 59 and the side guide plate 51. When the cylinder 58 resets, vibrate the middle guide plate 59 and the side guide plate 51 again to completely shake off the wheat straw above them, avoiding local accumulation of wheat straw and thus affecting the original laying progress.
