Description

Technical Field

[0001] This invention relates to the technical field, specifically to a soil loosening device for the treatment of saline-alkali land with adjustable depth. Background Technology

[0002] The transformation of agricultural land into saline-alkali land is the result of both natural and human factors. Saline-alkali soil is compacted, with poor aeration and permeability. Therefore, it is necessary to loosen the soil to reduce surface salt concentration, improve soil fertility, and promote root development and expansion. After loosening the soil, it is also necessary to spray an alkalinity-improving solution to reduce soil alkalinity and improve vegetation survival rate. For example, Chinese utility model patent application number "CN202122492751.8" provides a soil loosening device for saline-alkali land. In use, a motor drives an auger to rotate. After the auger enters the soil, it pushes the frame to move. During this movement, the rotation of the auger loosens the soil. The alkalinity-improving solution flows into a telescopic pipe through a guide channel and exits from the outlet end of the telescopic pipe, flowing onto the ground where the soil loosened by the auger has been. The telescopic pipe can move and bend freely, and the orientation of the outlet end can be adjusted according to actual conditions.

[0003] The drawback of this device is that the telescopic tube requires manual control by the operator to change the orientation of the outlet end. However, the bottom of the telescopic tube is very close to the auger, which makes it easy for the operator's hand to touch the auger, causing injury to the operator's hand. Summary of the Invention

Detailed Implementation

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Please see Figure 1-16This invention provides a technical solution: a soil loosening device for saline-alkali land treatment with adjustable depth, comprising a frame 1, a loosening component 2, a first adjusting component 3, a liquid storage component 4, a spraying component 5, and a second adjusting component 6. The frame 1 includes a support plate 11, wheels 12, and handles 13. The loosening component 2 includes an adjusting frame, a first motor, and an auger. The first adjusting component 3 includes a first electric telescopic rod and a first disc. The operator can move the frame 1 using the handles 13 and wheels 12. When loosening is needed, the first adjusting component 3 operates. The output of the first electric telescopic rod extends, driving the first motor and the auger downwards together via the first disc and adjusting frame. The first motor drives the auger to rotate. When the auger enters the soil, it moves with the frame 1, completing the soil loosening work. The liquid storage component 4 includes a storage tank and a delivery pipe. The spraying component 5 includes a storage box 51, a spray box 52, and an electrically controlled valve 53. The alkalinity improver solution in the storage tank 51 can be stored in the storage tank 51 through the infusion tube, while the electrically controlled valve 53 is in the closed state. When it is necessary to spray the alkalinity improver solution onto the soil, the electrically controlled valve 53 opens, and the alkalinity improver solution in the storage tank 51 enters the spray box 52 and is sprayed onto the soil through the spray box 52 to reduce soil alkalinity. When it is necessary to adjust the spraying direction and position of the alkalinity improver solution, the second adjustment component 6 moves the storage tank 51 and the spray box 52 together, thereby changing the position of the spray box 52 so that the spray box 52 can spray the alkalinity improver solution onto the soil from different directions. The entire process does not require the operator to touch the spraying component 5, so the operator's hands can be kept away from the auger, avoiding injury to the operator.

[0036] Example 1

[0037] Please see Figure 1-3 , Figure 8-10 and Figure 13-14 The invention also includes a dispensing box 7. Both the storage box 51 and the dispensing box 7 are annular structures. The soil loosening component 2 is located inside the dispensing box 7. The storage box 51 and the spraying box 52 are both located inside the dispensing box 7. The bottom of the spraying box 52 is provided with a drain port 522, and the bottom of the dispensing box 7 is provided with several drain holes 72. When the electrically controlled valve 53 is opened, the alkalinity improving solution in the storage box 51 enters the spraying box 52, and then exits the dispensing box 7 through the drain port 522 and the drain holes 72 in sequence, and is sprayed onto the soil. The second adjusting component 6 includes a second motor, a gear, and an annular rack. The side wall of the dispensing box 7 is provided with an annular assembly port 74, and the annular rack is located in the annular assembly port 74 and is fixedly connected to the outer side wall of the storage box 51. When it is necessary to adjust the spraying direction and position of the alkalinity improver, the second motor drives the gear to rotate. The gear meshes with the ring rack, and the ring rack drives the storage box 51 and the spray box 52 to make a circular motion, changing the position of the spray box 52 in the distribution box 7. Therefore, the drain port 522 can be aligned with the drain hole 72 at different positions.

[0038] Please see Figure 10-11 and Figure 14 The bottom of the liquid distribution box 7 has a first protrusion 71, and drainage holes 72 are provided on both sides of the first protrusion 71. The bottom of the liquid application box 52 has two second protrusions 521, and drainage ports 522 are provided on the opposite sides of the two second protrusions 521. The alkalinity improving liquid in the liquid application box 52 can be sprayed out from the drainage ports 522 on either side, so that the alkalinity improving liquid can be sprayed on the soil of the liquid distribution box 7 near the auger and on the soil of the liquid distribution box 7 away from the auger. The interior of the liquid application box 52 has a first arc-shaped partition 523, which divides the interior of the liquid application box 52 into two drainage chambers 524. The two drainage chambers 524 are not connected, and there are two electrically controlled valves 53, one above each of the two drainage chambers 524. When all the electrically controlled valves 53 are open, the alkalinity improver in the storage box 51 can simultaneously enter the two drainage chambers 524. At this time, the alkalinity improver will be sprayed outward from the drainage ports 522 on both sides and the drainage holes 72 on both sides. When it is only necessary to spray the alkalinity improver onto one side of the distribution box 7, simply close one of the electrically controlled valves 53. The alkalinity improver in the storage box 51 can enter one drainage chamber 524. At this time, only the drainage port 522 on one side and the drainage hole 72 on one side will spray outward from the alkalinity improver.

[0039] Please see Figure 1-3 and Figure 8-14 The width of the drain outlet 522 is greater than the width of the drain hole 72. The interior of the first protrusion 71 is also provided with a first retaining ring 54 and a second retaining ring 55, both of which are fixedly connected to the spray box 52. As the spray box 52 continuously rotates and changes position, and delivers alkalinity-improving liquid to the drain hole 72 through the drain outlet 522, the first retaining ring 54 and the second retaining ring 55 can rotate along with the spray box 52. The first retaining ring 54 and the second retaining ring 55 can block drain holes 72 that are not aligned with the drain outlet 522, ensuring that the alkalinity-improving liquid can only be sprayed from drain holes 72 aligned with the drain outlet 522, thus enhancing the accuracy of spraying the alkalinity-improving liquid in this invention. A second arc-shaped baffle 73 is provided at the bottom of the inner wall of the first protrusion 71. The second arc-shaped baffle 73 divides the interior of the first protrusion 71 into two spaces, thereby ensuring that no matter which side's drain hole 72 sprays alkalinity-improving liquid outward, the alkalinity-improving liquid will not move inside the first protrusion 71 to the other side, and therefore will not spray outward from the drain hole 72 on the other side. The second arc-shaped baffle 73 is located between the first liquid ring 54 and the second liquid ring 55. Both the first liquid ring 54 and the second liquid ring 55 can slide along the outer surface of the second arc-shaped baffle 73, enhancing the stability of the spraying assembly 5 during rotation.

[0040] Example 2

[0041] Please see Figure 1-6 and Figure 15-16 The invention also includes a third adjusting component 8, which comprises an adjusting plate 81, an elastic rod 82, and a limiting component 83. The spraying component 5 and the second adjusting component 6 are both fixedly connected to the adjusting plate 81, which is connected to the first disc in the first adjusting component 3 via the elastic rod 82. Since the auger needs to move up and down to change its insertion depth into the soil, the position of the spraying component 5 also needs to be adjusted accordingly. With the combined action of the first adjusting component 3 and the limiting component 83, the spraying component 5 can move downwards synchronously with the auger, remain stationary, or move upwards relative to the auger.

[0042] Please see Figure 1-6 and Figure 15-16 When the spraying assembly 5 and the auger need to maintain a constant relative position, the first adjusting assembly 3 operates, extending the output end of the first electric telescopic rod. The first disc, while driving the first motor and the auger downwards, also drives the adjusting plate 81, spraying assembly 5, and second adjusting assembly 6 downwards via the elastic rod 82. At this time, the spraying assembly 5 is closer to the soil surface, and the second adjusting assembly 6 can drive the spraying assembly 5 to move normally, adjusting the spraying direction and position of the alkalinity amendment solution.

[0043] Please see Figure 1-6 and Figure 15-16The limiting component 83 includes a support member 831 and a fourth adjusting component 832. The fourth adjusting component 832 includes a second electric telescopic rod and a second disc. The second electric telescopic rod is fixedly connected to the frame 1, and its output end and elastic rod 82 are both connected to the second disc. A third protrusion 811 is provided on the side wall of the adjusting plate 81. The bottom of the support member 831 has an inverted T-shaped structure, and the top of the support member 831 passes through the third protrusion 811 and is connected to the second disc. To ensure that the spraying component 5 does not collide with the ground, the output end of the second electric telescopic rod extends first, causing the bottom of the support member 831 to move to a suitable position. When the spraying component 5 needs to remain in place, the first adjusting component 3 operates, the output end of the first electric telescopic rod extends, causing the adjusting plate 81, the spraying component 5, and the second adjusting component 6 to move downward together. The third protrusion 811 slides along the middle of the support member 831 and gradually approaches the bottom of the support member 831. When the third protrusion 811 contacts the bottom of the support member 831, the bottom of the support member 831 acts as a barrier to the third protrusion 811, and the adjusting plate 81, spraying assembly 5, and second adjusting assembly 6 no longer move downwards, preventing the spraying assembly 5 from colliding with the ground. At this time, the elastic rod 82 undergoes elastic deformation and stores elastic potential energy, allowing the first disc to still drive the first motor and the auger to descend into the soil. When the output end of the first electric telescopic rod shortens and the first disc moves upwards, the elastic rod 82 releases its elastic potential energy and extends, ultimately causing the first motor and the auger to move upwards and reset together with the adjusting plate 81, spraying assembly 5, and second adjusting assembly 6.

[0044] Please see Figure 1-6 and Figure 15-16 When the spraying component 5 needs to move upward relative to the auger, the fourth adjusting component 832 operates, the output end of the second electric telescopic rod shortens, and the second disc drives the support member 831 to move upward. After the bottom of the support member 831 contacts the third protrusion 811, it can directly drive the adjusting plate 81, the spraying component 5, and the second adjusting component 6 to move upward together, so that the spraying component 5 is away from the auger. At this time, the elastic rod 82 undergoes elastic deformation and stores elastic potential energy. When the output end of the second electric telescopic rod extends, and the second disc drives the support member 831 to move downward, the bottom of the support member 831 moves away from the third protrusion 811, and the elastic rod 82 can release its elastic potential energy and extend. The elastic rod 82 drives the adjusting plate 81, the spraying component 5, and the second adjusting component 6 to move downward and reset together.
