Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of saline-alkali soil improvement, and more particularly to an efficient saline-alkali soil improvement device. BACKGROUND

[0002] The essence of saline-alkali soil formation is mainly the redistribution of various easily soluble salts in the horizontal and vertical directions on the ground, so that the salt gradually accumulates in the soil surface layer in the salt accumulation area. In the field of agriculture, land salinization not only endangers the soil conditions on which crops depend for survival, but also harms crop growth, causing crop seedlings to be sparse or even death, thereby hindering the development of agricultural production. Soil salinization is an important limiting factor for the development of local agricultural economy.

[0003] The existing saline-alkali soil improvement is mostly by spraying the saline-alkali soil with an improvement agent. However, the salt in the saline-alkali soil flows upward from the underground, and the desulfurized gypsum only stays on the surface of the land and cannot contact the deep soil layer, so that the desulfurized gypsum cannot fully contact the salt in the saline-alkali soil, thereby resulting in poor improvement effect.

[0004] In view of the above problems, some solutions are also given in the prior art. For example, a method and device for improving and treating saline-alkali soil are disclosed in Chinese Patent No. CN119183717B. The device is provided with a medicine spraying part. After the plowing assembly is inserted into the land to turn up the soil, the motor drives the rotating pipe and the plug-in feeding assembly to rotate. The improvement agent placed in the material box flows out from the end of the plug-in feeding assembly through the material groove and the retaining ring in turn. The rotating plug-in feeding assembly is inserted into the soil, and the flowing improvement agent is poured into the deep soil to act, so that the improvement agent fully contacts the salt in the deep soil, and the improvement effect is improved. However, there are still some limitations in actual use. During the crushing process of the soil by the feeding assembly, the soil solution clogs the feeding assembly, and then the solution affects the normal flow of the improvement liquid to the soil. Although the existing technology sets the cooperation of the stop piece and the baffle, the baffle can block the feeding assembly after the feeding assembly is far away from the soil, but part of the soil may inevitably enter the inside of the feeding assembly. If the soil cannot be cleaned in time, the feeding assembly may be clogged. In addition, the stop piece is exposed to the outside, and the soil may be stuck on the stop piece, thereby affecting the normal blocking of the feeding assembly by the baffle, and then affecting the normal spraying of the improvement liquid to the saline-alkali soil, thereby seriously affecting the improvement effect of the saline-alkali soil.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the application will be clearly and completely described below with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are only some of the embodiments of the application, but not all the embodiments of the application. Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the application.

[0022] Please refer to Figures 1 to 8 A high-efficiency saline-alkali soil improvement device, comprising a frame body 1, a plow 2 is fixedly installed on the frame body 1, a bracket 3 is fixedly installed on the side wall of the frame body 1, a hopper 4 is fixedly installed on the frame body 1, and a feeding assembly 5 cooperating with the hopper 4 is arranged on the frame body 1. The feeding assembly 5 includes a rotating rod 501 rotatably mounted on a frame 1, and a motor 502 with its output end fixedly connected to the rotating rod 501 is fixedly mounted on the frame 1. Crushing plates 503 are uniformly fixedly mounted on the rotating rod 501. A cavity 504 is formed in the rotating rod 501, and a horizontal rod 506 fixedly connected to the frame 1 is rotatably mounted inside the cavity 504. A feeding trough 507 is formed on the crushing plate 503, and a connecting port 508 communicating with the feeding trough 507 is formed in the cavity 504. The feeding trough 507 has a feeding port, and a blocking rod 509 is slidably installed in the feeding port. A linkage block 510 is fixedly installed on the blocking rod 509, and a first spring 512 is installed between the linkage block 510 and the feeding trough 507. A linkage rod 505 is fixedly installed on the linkage block 510. An arc-shaped groove 511 that cooperates with the linkage rod 505 is opened on the horizontal rod 506. A connecting component 6 is provided on the rotating rod 501, and the cavity 504 is connected to the material box 4 through the connecting component 6.

[0023] In use, the operator can connect the soil amendment device to the traction vehicle via the bracket 3. As the traction vehicle pulls the amendment device, the plow blade 2 turns over the soil, exposing the deep soil and breaking up clumps of saline-alkali soil to facilitate the mixing of soil amendment. Simultaneously, the motor 502 drives the rotating rod 501 to rotate, which in turn drives the crushing plate 503 to rotate. The rotation of the crushing plate 503 breaks up large pieces of surface soil and also drives the linkage... When rod 505 rotates, and the crushing plate 503 rotates to its lowest point, linkage rod 505 contacts arc groove 511. At this time, the first spring 512 extends and drives linkage block 510 to move. Then, during the movement of linkage block 510, linkage rod 505 moves into arc groove 511. At the same time, during the movement of linkage block 510, sealing rod 509 disengages from feed port. At this time, the improvement liquid in material box 4 flows into deep soil through cavity 504, connecting port 508, feed trough 507, and feed port, which plays a role in improving the improvement effect of saline-alkali land.

[0024] When the rotating rod 501 drives the crushing plate 503 away from the lowest point, the crushing plate 503 drives the linkage rod 505 to disengage from the arc groove 511. Then, under the action of the arc surface of the arc groove 511, the linkage rod 505 moves along the feeding groove 507. During the movement of the linkage rod 505, the blocking rod 509 is driven into the feeding port through the linkage block 510. At this time, the first spring 512 is compressed and has a tendency to recover. After the blocking rod 509 enters the feeding port, it can prevent soil from blocking the feeding port. When the blocking rod 509 enters the feeding port, it can push out the soil remaining in the feeding port, effectively preventing soil accumulation in the feeding port from causing blockage and affecting the application effect of the soil amendment liquid, thus further improving the effect of saline-alkali land improvement.

[0025] like Figure 2 , Figure 6 As shown, the connecting component 6 includes an annular plate 601 rotatably mounted on a rotating rod 501. An annular groove communicating with the cavity 504 is provided on the annular plate 601. A piston plate 602 is vertically slidably mounted inside the material box 4. A drain valve 603 is inserted into the material box 4. A water pipe 604 communicating with the annular groove is fixedly installed on the output end of the drain valve 603. An inlet valve 605 communicating with the material box 4 is fixedly installed on the piston plate 602.

[0026] A second spring 606 is installed between the piston plate 602 and the material box 4. A vertical rod 607 is fixedly installed on the bottom wall of the piston plate 602. A push rod 608 that cooperates with the vertical rod 607 is fixedly installed on the rotating rod 501, and the top end of the push rod 608 is inclined.

[0027] By adopting the above technical scheme, the push rod 608 is rotated in the process of rotation of the rotating rod 501, and in the process of rotation of the push rod 608, the inclined surface of the push rod 608 gradually contacts the vertical rod 607 and applies a pushing force to the vertical rod 607, and then the vertical rod 607 moves upward under the action of the pushing force, and in the process of upward movement of the vertical rod 607, the piston plate 602 is moved upward, at this time the second spring 606 is stretched and has a restoring tendency, and in the process of downward movement of the piston plate 602, the space below the material box 4 sucks in the modified liquid through the water inlet valve 605, then after the push rod 608 and the vertical rod 607 are disengaged, the second spring 606 is contracted and drives the piston plate 602 to move downward, in the process of downward movement of the piston plate 602, the modified liquid below the piston plate 602 in the material box 4 is extruded and extruded into the annular groove through the liquid outlet valve and the water pipe 604, then the high-pressure modified liquid flows into the cavity 504 through the annular groove, when the plugging rod 509 is disengaged from the feeding port, the high-pressure modified liquid can quickly flow into the deep soil through the feeding port, and when the feeding assembly 5 needs to be maintained, the user only needs to close the motor 502, at this time the piston plate 602 stops moving, so that the modified liquid stops flowing into the cavity 504, effectively avoiding the modified liquid flowing into the ground to affect the modification effect, and further improving the saline-alkali soil modification effect.

[0028] As shown in Figure 4 , Figure 5 , Figure 6 The top wall of the piston plate 602 is rotatably provided with a mounting rod 701, and the mounting rod 701 is uniformly and fixedly provided with a mixing rod 702.

[0029] A sliding groove is formed in the top wall of the mounting rod 701, a circular rod 703 is fixedly installed on the top wall of the material box 4 and slidably matched with the sliding groove, a rotating groove 704 is formed in the side wall of the sliding groove, and a protrusion 705 is fixedly installed on the circular rod 703 and slidably matched with the rotating groove 704.

[0030] A first groove 706 is horizontally formed in the mixing rod 702, a second groove 707 is vertically formed in the mounting rod 701, and the first groove 706 and the second groove 707 are communicated, and a water hole 708 is uniformly formed in the first groove 706.

[0031] By adopting the above technical scheme, in the process of reciprocating movement of the piston plate 602, the piston plate 602 drives the mounting rod 701 to move, and in the process of movement of the mounting rod 701, the mixing rod 702 is driven to move, so that the vertical direction stirring in the material box 4 can be carried out, and in the process of reciprocating movement of the mounting rod 701, the round rod 703 drives the protrusion 705 to move along the rotating groove 704, then in the process of movement of the protrusion 705 along the rotating groove 704, the mounting rod 701 can be driven to rotate, and in the process of rotation of the mounting rod 701, the mixing rod 702 can be driven to rotate, so that the horizontal direction stirring of the material box 4 can be carried out, effectively avoiding the stratification and sedimentation of the improvement liquid, and further improving the improvement effect of the saline-alkali soil.

[0032] In the process of upward movement of the piston plate 602, the space below the piston plate 602 in the material box 4 sucks the improvement liquid from the second groove body 707 through the water inlet valve 605, and then the second groove body 707 sucks the improvement liquid at different depths through the water hole 708 on the first groove body 706, thereby further improving the uniformity of the improvement liquid spraying concentration and further improving the improvement effect of the saline-alkali soil.

[0033] As shown in Figure 3 , the linkage rod 505 is uniformly and fixedly installed with a limiting ring 8, and the limiting ring 8 and the feeding groove 507 are jointly installed with a connecting rod 9.

[0034] The end of the linkage rod 505 close to the horizontal rod 506 is fixedly installed with a ball 10.

[0035] By adopting the above technical scheme, in the process of movement of the linkage rod 505, the limiting ring 8 can be arranged to limit the linkage rod 505, and then the plugging rod 509 fixedly connected with the linkage block 510 and the linkage rod 505 can be limited, so that the plugging rod 509 can be normally inserted into the feeding port, and in the process of rotation of the linkage rod 505 driven by the crushing plate 503, the ball 10 can be arranged to convert the sliding friction between the linkage rod 505 and the horizontal rod 506 into the rolling friction between the horizontal rod 506 and the ball 10, so as to reduce the resistance of the rotation of the linkage rod 505 and the wear of the linkage rod 505 and the horizontal rod 506, and to ensure the normal operation of the device.

[0036] As shown in Figure 2 , Figure 5 , Figure 6 , the surface of the protrusion 705 is a smooth mirror surface.

[0037] The vertical rod 607 and the push rod 608 are symmetrically provided with two groups.

[0038] By adopting the technical scheme, in the process that the push rod 608 drives the piston plate 602 to move upward through the vertical rod 607, the two groups of vertical rods 607 and the push rod 608 are symmetrically arranged, so that the piston plate 602 can be uniformly stressed, the piston plate 602 can be prevented from being stuck due to uneven stress, the surface of the convex block 705 is smooth, in the process that the piston plate 602 drives the rotating groove 704 to move through the mounting rod 701, the friction between the rotating groove 704 and the convex block 705 can be reduced, and the normal operation of the device is ensured.

[0039] Method for use: in the process that the rotating rod 501 rotates, the push rod 608 rotates, and in the process that the push rod 608 rotates, the push rod 608 drives the piston plate 602 to move upward through the vertical rod 607, and in the process that the piston plate 602 moves downward, the space below the material box 4 sucks in the modified liquid through the water inlet valve 605, then after the push rod 608 is separated from the vertical rod 607, the second spring 606 is contracted and drives the piston plate 602 to move downward, in the process that the piston plate 602 moves downward, the modified liquid below the piston plate 602 in the material box 4 is extruded and is extruded into the annular groove through the liquid outlet valve and the water pipe 604, and then the high-pressure modified liquid flows into the cavity 504 through the annular groove. At the same time, the motor 502 drives the rotating rod 501 to rotate, and in the process that the rotating rod 501 rotates, the crushing plate 503 rotates, then in the process that the crushing plate 503 rotates, the surface layer of the large block of soil can be crushed, and in the process that the crushing plate 503 rotates, the linkage rod 505 is driven to rotate, when the crushing plate 503 rotates to the lowest point, the linkage rod 505 is in contact with the arc-shaped groove 511, at this time, the first spring 512 is stretched and drives the linkage block 510 to move, then in the process that the linkage block 510 moves, the linkage rod 505 moves into the arc-shaped groove 511, at the same time, in the process that the linkage block 510 moves, the plugging rod 509 is separated from the feeding port, at this time, the modified liquid in the material box 4 flows to the deep soil through the cavity 504, the communication port 508, the feeding groove 507 and the feeding port.

[0040] In addition, in the process that the piston plate 602 reciprocates up and down, the piston plate 602 drives the mounting rod 701 to move, and in the process that the mounting rod 701 moves, the mixing rod 702 is driven to move, so that the material box 4 can be stirred in the vertical direction, and in the process that the mounting rod 701 reciprocates up and down, the round rod 703 drives the convex block 705 to move along the rotating groove 704, then in the process that the convex block 705 moves along the rotating groove 704, the mounting rod 701 can be driven to rotate, and in the process that the mounting rod 701 rotates, the mixing rod 702 can be driven to rotate, so that the material box 4 can be stirred in the horizontal direction, and the stratification and precipitation of the modified liquid can be effectively avoided.

[0041] In the course of upward movement of the piston plate 602, the space in the hopper 4 below the piston plate 602 sucks the modified liquid from the second groove 707 through the water inlet valve 605, and then the second groove 707 sucks the modified liquid of different depths through the water hole 708 on the first groove 706.
