Description

Technical Field

[0001] The present invention relates to the technical field of soil improvement, and more particularly to a saline-alkali land improvement and salt-alkali blocking device. Background Art

[0002] With the development of globalization and the increasing shortage of land resources, people are paying more and more attention to the transformation and utilization of saline-alkali land. However, due to the high salinity of the soil, saline-alkali land makes it difficult for crops to grow, thereby greatly reducing agricultural production efficiency.

[0003] Currently, most of the saline-alkali land improvement methods on the market use artificial irrigation and fertilization, but these methods are costly and inefficient, and it is difficult to fundamentally solve the problem of continuous salinization of saline-alkali land.

[0004] The Chinese patent with authorization announcement number: CN117501871B discloses a salt-alkali barrier device for improving saline-alkali land, which can prevent the improvement chemicals from being directly exposed to the air and in contact with high temperatures for a long time, causing the improvement chemicals to volatilize and affect the improvement effect.

[0005] The above patent still has the following deficiencies:

[0006] During the work process, due to the numerous procedures and complicated operations, work efficiency is significantly reduced, especially when large-scale improvements are required, the efficiency is particularly low. The cumbersome steps and complicated operating procedures not only increase the workload, but also easily make the staff feel tired when handling tasks, further affecting the overall work efficiency.

[0007] Therefore, a salt-alkali barrier device for improving saline-alkali land is proposed. Summary of the Invention

[0008] In view of the problems existing in the prior art, the purpose of the present invention is to provide a salt-alkali barrier device for improving saline-alkali land, which can improve work efficiency.

[0009] To solve the above problems, the present invention adopts the following technical solutions.

[0010] A saline-alkali soil improvement and salt-alkali blocking device comprises a frame, a connecting piece and a medicine box provided on the frame, wherein the medicine box contains liquid improvement medicine, and the frame can be mounted on a vehicle frame through the connecting piece so that the frame can be driven by the vehicle to move; a crushing mechanism for crushing the soil is provided on the frame;

[0011] A crossbar is horizontally mounted on the inner walls of opposite sides of the frame, and the crossbar and the connecting piece are located on both sides of the crushing mechanism respectively;

[0012] A telescopic rod is installed on the horizontal bar, and a catheter is rotatably installed on the output end of the telescopic rod. A drain pipe is inserted into the output end of the telescopic rod. The two ends of the drain pipe are respectively connected to the output end of the medicine box and the catheter. The catheter is open at one end close to the drain pipe, and the drain pipe extends into the catheter, so that the drain pipe can be connected to the catheter. Holes are evenly opened on the side wall of the catheter, and the holes are used to discharge the liquid modified medicine in the catheter.

[0013] Friction blocks are evenly arranged on the outer wall of the catheter, and a first motor for driving the catheter to rotate is embedded on the output end of the telescopic rod. The output end of the first motor is fixedly connected to the center of the catheter end wall.

[0014] The crushing mechanism includes a rotating rod rotatably mounted on the frame, with rotary blades evenly mounted on the rotating rod. A magnetic coupling and a second motor are provided on the frame. The output shaft of the magnetic coupling is fixedly connected to the rotating rod, and the output end of the second motor is fixedly connected to the drive shaft of the magnetic coupling.

[0015] First, the frame is connected to the vehicle through a connecting piece, and then the frame is driven by the vehicle to move; during the movement of the frame, the second motor is first turned on, and the second motor drives the rotating rod and the rotary blade to rotate through the magnetic coupling, so that the soil can be broken up by the rotary blade;

[0016] After the soil is broken up, the staff adjusts the extension of the telescopic rod according to the depth of the broken soil, and at the same time starts the first motor, which drives the guide tube to rotate. During the rotation of the guide tube, the friction block can push away the broken soil below the guide tube, and the guide tube can move downward normally, thereby driving the guide tube to move below the broken soil through the output end of the telescopic rod, and then the broken soil above the guide tube collapses, so that the guide tube is buried by the broken soil;

[0017] Then open the output end of the medicine box. At this time, the liquid improvement medicine in the medicine box flows along the drain pipe into the catheter, and then is discharged through the holes on the catheter. The improvement medicine discharged from the holes comes into contact with the crushed soil, thereby improving the soil; therefore, the soil improvement can be completed in the process of the vehicle driving the entire device to move.

[0018] In the process of the first motor driving the catheter to rotate, the broken soil in contact with the friction block is driven by the friction block under the action of friction force, so that the part of the broken soil that has been in contact with the improvement agent near the catheter can be transferred. After this part of the broken soil is transferred, the broken soil in the space above the catheter will fall to the surface of the catheter, thereby increasing the contact area between the improvement agent and the broken soil and improving the improvement effect on the soil.

[0019] Moreover, the conduit is submerged in the crushed soil, thus preventing the liquid improvement medicine from being directly exposed to sunlight and directly contacting the air, reducing the volatilization of effective substances in the improvement medicine, improving the utilization efficiency of the improvement medicine, and playing a role in improving work efficiency and enhancing the improvement effect.

[0020] The frame can limit the movement range of the crushed soil, and the side walls of the frame can flatten the piled-up crushed soil, thereby ensuring that the ground remains flat.

[0021] Furthermore, a mounting rod is horizontally fixedly installed on the inner side wall of the conduit near one end of the first motor, and baffles are evenly fixedly installed on the mounting rod, and the baffles are matched with the holes.

[0022] During the rotation of the catheter, the baffle is driven to rotate by the mounting rod. At this time, the liquid improvement medicine in the catheter is pushed by the baffle. At this time, the improvement medicine makes a circular motion along with the baffle, that is, the improvement medicine in the catheter has centrifugal force. Therefore, when the improvement medicine is discharged through the hole, the impact force of the improvement medicine is increased, so that when the improvement medicine hits the broken soil, the improvement medicine is broken up by the impact force, further increasing the contact probability between the improvement medicine and the broken soil, and improving the improvement effect on the soil.

[0023] Furthermore, a socket is provided on the side wall of the catheter, a connecting rod is slidably inserted into the socket, a friction block is fixedly installed on the end of the connecting rod, an elastic part is installed between the connecting rod and the inner wall of the catheter, and a driving mechanism is provided in the catheter to drive the connecting rod to extend out of the catheter.

[0024] Furthermore, the driving mechanism includes a mounting groove on the baffle, which is located on the side wall of the baffle close to the mounting rod. The mounting rod is a reciprocating screw rod, and a slider is threadedly mounted on the reciprocating screw rod, and the side wall of the slider is an inclined surface.

[0025] During the rotation of the catheter, the catheter drives the reciprocating screw to rotate, and the slider reciprocates along the reciprocating screw.

[0026] When the slider with the inclined side wall contacts the connecting rod, the slider pushes the connecting rod out of the insertion hole under the action of the inclined surface, and the elastic member is stretched. At this time, the connecting rod drives the friction block to push the crushed soil around the catheter that has been in contact with the modified medicine, so that the crushed soil in the space above the catheter is away from the catheter, and the crushed soil below the catheter is squeezed and crushed by the friction block;

[0027] When the crushed soil above the conduit that has been in contact with the improving drug is pushed away, the remaining crushed soil above the conduit will fall onto the conduit surface, and this part of the crushed soil can now come into contact with the improving drug;

[0028] When the broken soil below the tube is squeezed and crushed, the contact area between the crushed small pieces of soil and the improvement medicine is further increased, thereby improving the improvement effect.

[0029] Therefore, in the process of the connecting rod driving the friction block to move, the improvement effect is improved.

[0030] Among them, during the rotation of the reciprocating screw, the slider threadedly mounted on the reciprocating screw is driven to perform reciprocating motion along the reciprocating screw, which is a prior art and will not be described in detail.

[0031] In addition, when the connecting rod drives the friction block to move, the friction block can move on the surface of the crushed soil, thereby improving the crushing effect of the crushed soil, grinding the blocky crushed soil into powder, and further increasing the contact area between the improvement medicine and the soil.

[0032] Furthermore, a pressure relief hole is provided on the side wall of the catheter, and the pressure relief hole is used to discharge the improved medicine, and the pressure relief hole cooperates with the connecting rod.

[0033] Furthermore, the elastic member is an elastic bellows, which is sleeved on the connecting rod, and the two ends of the elastic bellows are respectively connected to the connecting rod and the conduit;

[0034] A cavity is provided on the elastic bellows, a one-way valve and a pressure relief valve are embedded on the side wall of the cavity, and an output end of the pressure relief valve is communicated with the pressure relief hole.

[0035] During the movement of the connecting rod, the connecting rod drives the elastic bellows to expand and contract;

[0036] When the elastic bellows stretches, the cavity is in a negative pressure state, and the cavity absorbs liquid from the catheter through the one-way valve;

[0037] When the elastic bellows contracts, the liquid in the cavity is squeezed and discharged into the pressure relief hole through the pressure relief valve. At this time, the liquid discharged from the pressure relief hole impacts the surface of the friction block, which can clean the surface of the friction block and enable the outer wall of the friction block to directly contact the crushed soil, ensuring that there is sufficient friction between the friction block and the crushed soil, and playing a role in ensuring that the friction block can push the crushed soil away.

[0038] Furthermore, an impact block is fixedly mounted on the side wall of the connecting rod.

[0039] At the moment when the connecting rod is extended to the maximum from the socket, the connecting rod drives the impact block to hit the inner wall of the tube, thereby transmitting the impact force to the impurities adhering to the surface of the friction block, shaking off the impurities and playing a role in assisting in cleaning the friction block.

[0040] Furthermore, the bottom wall of the output end of the telescopic rod is tapered, thereby facilitating the insertion of the telescopic rod into crushed soil.

[0041] Furthermore, a guide groove is provided on the connecting rod, one end of the guide groove is located in the conduit and is communicated with the conduit, and small holes are evenly provided on the outer wall of the guide groove.

[0042] The liquid medicine in the catheter flows into the guide groove, and then the liquid in the guide groove is discharged through the small hole. At the moment when the small hole breaks contact with the edge of the socket, the liquid medicine discharged from the small hole cleans out the impurities at the contact point between the connecting rod and the catheter. When the connecting rod retracts into the catheter, the friction between the catheter and the side wall of the socket is reduced, thereby protecting the catheter and the side wall of the socket.

[0043] At the same time, in the process of the small hole moving to the outside of the catheter, the position of the small hole is in a changing state, thereby increasing the probability of the liquid medicine discharged from the small hole contacting the crushed soil, further improving the improvement effect.

[0044] Compared with the prior art, the present invention has the following beneficial effects:

[0045] (1) This solution uses a first motor to drive the conduit to rotate. During the rotation of the conduit, the friction block can push away the broken soil below the conduit, and the output end of the telescopic rod drives the conduit to move below the broken soil. Then, the broken soil above the conduit collapses, and the conduit is buried by the broken soil. The liquid improvement medicine in the medicine box flows along the drainage pipe into the conduit, and is then discharged through the holes on the conduit. The improvement medicine discharged from the holes contacts the broken soil, thereby improving the soil. Therefore, the soil improvement can be completed in the process of the vehicle driving the entire device to move.

[0046] (2) This solution drives the conduit to rotate by the first motor, so that the crushed soil in contact with the friction block is driven by the friction block under the action of friction, thereby enabling the part of the crushed soil in contact with the improvement agent near the conduit to be transferred. After this part of the crushed soil is transferred, the crushed soil in the space above the conduit will fall onto the surface of the conduit, thereby increasing the contact area between the improvement agent and the crushed soil and improving the improvement effect on the soil.

[0047] (3) In this solution, the connecting rod is pushed out of the socket by the slider, and the elastic part is stretched. At this time, the connecting rod drives the friction block to push the crushed soil around the catheter that has been in contact with the improvement drug, so that the crushed soil in the space above the catheter is away from the catheter, and the crushed soil below the catheter is squeezed and crushed by the friction block; when the crushed soil above the catheter that has been in contact with the improvement drug is pushed away, the remaining crushed soil above the catheter will fall to the surface of the catheter, and at this time this part of the crushed soil can come into contact with the improvement drug; when the crushed soil below the catheter is squeezed and crushed, the contact area between the crushed small pieces of soil and the improvement drug is further increased, thereby improving the improvement effect.

[0057] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. Example 1:

[0058] See also Figures 1 to 7 A saline-alkali land improvement and salt-alkali barrier device comprises a frame 1, a connecting piece 2 and a medicine box 3 are provided on the frame 1, and the medicine box 3 contains liquid improvement medicine. The frame 1 can be mounted on a vehicle frame through the connecting piece 2, so that the frame 1 can be moved by the vehicle; the frame 1 is provided with a crushing mechanism for crushing the soil;

[0059] A crossbar 4 is horizontally mounted on the inner walls of opposite sides of the frame 1. The crossbar 4 and the connecting piece 2 are located on both sides of the crushing mechanism.

[0060] A telescopic rod 5 is mounted on the crossbar 4, and a conduit 6 is rotatably mounted on the output end of the telescopic rod 5. A drain pipe 7 is inserted into the output end of the telescopic rod 5. The two ends of the drain pipe 7 are respectively connected to the output end of the medicine box 3 and the conduit 6. The conduit 6 is open at one end close to the drain pipe 7, and the drain pipe 7 extends into the conduit 6, so that the drain pipe 7 can be connected to the conduit 6. Holes 8 are evenly opened on the side wall of the conduit 6, and the holes 8 are used to discharge the liquid modified medicine in the conduit 6;

[0061] Friction blocks 9 are evenly arranged on the outer wall of the conduit 6 , and a first motor 10 for driving the conduit 6 to rotate is embedded on the output end of the telescopic rod 5 . The output end of the first motor 10 is fixedly connected to the center of the end wall of the conduit 6 .

[0062] The crushing mechanism includes a rotating rod 11 rotatably mounted on the frame 1, and rotary blades 12 are evenly mounted on the rotating rod 11. A magnetic coupling 13 and a second motor 14 are provided on the frame 1. The output shaft of the magnetic coupling 13 is fixedly connected to the rotating rod 11, and the output end of the second motor 14 is fixedly connected to the drive shaft of the magnetic coupling 13.

[0063] First, the frame 1 is connected to the vehicle through the connecting member 2, and then the frame 1 is driven by the vehicle to move; during the movement of the frame 1, the second motor 14 is first turned on, and the second motor 14 drives the rotating rod 11 and the rotary blade 12 to rotate through the magnetic coupling 13, so that the soil can be broken up by the rotary blade 12;

[0064] After the soil is broken up, the worker adjusts the extension of the telescopic rod 5 according to the depth of the broken soil, and at the same time starts the first motor 10, which drives the guide tube 6 to rotate. During the rotation of the guide tube 6, the friction block 9 can push away the broken soil below the guide tube 6. At this time, the guide tube 6 can move downward normally, and the output end of the telescopic rod 5 drives the guide tube 6 to move below the broken soil. Then, the broken soil above the guide tube 6 collapses, so that the guide tube 6 is buried by the broken soil.

[0065] Then open the output end of the medicine box 3. At this time, the liquid improvement medicine in the medicine box 3 flows along the drain pipe 7 into the conduit 6, and is then discharged through the hole 8 on the conduit 6. The improvement medicine discharged from the hole 8 comes into contact with the crushed soil, thereby improving the soil; therefore, the soil improvement can be completed in the process of the vehicle driving the entire device to move.

[0066] In the process of the first motor 10 driving the conduit 6 to rotate, the crushed soil in contact with the friction block 9 is driven by the friction block 9 under the action of friction force, so that the part of the crushed soil in contact with the improvement agent near the conduit 6 can be transferred. After this part of the crushed soil is transferred, the crushed soil in the space above the conduit 6 will fall to the surface of the conduit 6, thereby increasing the contact area between the improvement agent and the crushed soil and improving the improvement effect on the soil.

[0067] Moreover, the conduit 6 is submerged in the crushed soil, thus preventing the liquid improvement agent from being directly exposed to sunlight and directly contacting the air, thereby reducing the volatilization of the effective substances in the improvement agent, improving the utilization efficiency of the improvement agent, and playing a role in improving work efficiency and enhancing the improvement effect.

[0068] The frame 1 can limit the movement range of the crushed soil, and the side walls of the frame 1 can flatten the accumulated crushed soil, thereby ensuring that the ground remains flat.

[0069] like Figure 7 As shown, a mounting rod 15 is horizontally fixedly mounted on the inner side wall of the conduit 6 near one end of the first motor 10 , and baffles 16 are evenly fixedly mounted on the mounting rod 15 , and the baffles 16 cooperate with the holes 8 .

[0070] During the rotation of the conduit 6, the baffle 16 is driven to rotate by the mounting rod 15. At this time, the liquid improvement medicine in the conduit 6 is pushed by the baffle 16. At this time, the improvement medicine makes a circular motion along with the baffle 16, that is, the improvement medicine in the conduit 6 has centrifugal force. Therefore, when the improvement medicine is discharged through the hole 8, the impact force of the improvement medicine is increased, so that when the improvement medicine hits the broken soil, the improvement medicine is broken up by the impact force, further increasing the contact probability between the improvement medicine and the broken soil, and improving the improvement effect on the soil.

[0071] like Figure 4 As shown, a socket is provided on the side wall of the conduit 6, and a connecting rod 17 is slidably inserted into the socket. The friction block 9 is fixedly installed on the end of the connecting rod 17. An elastic member 18 is installed between the connecting rod 17 and the inner wall of the conduit 6, and a driving mechanism is provided in the conduit 6 to drive the connecting rod 17 to extend out of the conduit 6.

[0072] like Figure 4 As shown, the driving mechanism includes a mounting groove 19 opened on the baffle 16. The mounting groove 19 is located on the side wall of the baffle 16 close to the mounting rod 15. The mounting rod 15 is a reciprocating screw rod. A slider 20 is threadedly mounted on the reciprocating screw rod, and the side wall of the slider 20 is an inclined surface.

[0073] During the rotation of the guide tube 6, the guide tube 6 drives the reciprocating screw to rotate, and the slider 20 reciprocates along the reciprocating screw.

[0074] When the slider 20 with the inclined side wall contacts the connecting rod 17, the slider 20 pushes the connecting rod 17 out of the insertion hole under the action of the inclined surface, and the elastic member 18 is stretched. At this time, the connecting rod 17 drives the friction block 9 to push the crushed soil around the conduit 6 that has been in contact with the modified drug, so that the crushed soil in the space above the conduit 6 is moved away from the conduit 6, and the crushed soil below the conduit 6 is squeezed and crushed by the friction block 9;

[0075] When the crushed soil above the conduit 6 that has been in contact with the improving agent is pushed away, the remaining crushed soil above the conduit 6 will fall onto the surface of the conduit 6, and at this time, this part of the crushed soil can come into contact with the improving agent;

[0076] When the broken soil below the conduit 6 is squeezed and crushed, the contact area between the crushed small pieces of soil and the improvement agent is further increased, thereby improving the improvement effect.

[0077] Therefore, in the process of the connecting rod 17 driving the friction block 9 to move, the improvement effect is enhanced.

[0078] Among them, the slider 20 threadedly mounted on the reciprocating screw is driven to perform reciprocating motion along the reciprocating screw during the rotation of the reciprocating screw, which is a prior art and will not be described in detail.

[0079] In addition, when the connecting rod 17 drives the friction block 9 to move, the friction block 9 can move on the surface of the crushed soil, thereby improving the crushing effect of the crushed soil, grinding the blocky crushed soil into powder, and further increasing the contact area between the improvement drug and the soil.

[0080] like Figure 5 As shown, a pressure relief hole is provided on the side wall of the conduit 6 , the top of the pressure relief hole is inclined, the pressure relief hole is used to discharge the modified medicine, and the pressure relief hole cooperates with the linkage rod 17 .

[0081] like Figure 5 As shown, the elastic member 18 is an elastic bellows, which is sleeved on the connecting rod 17, and the two ends of the elastic bellows are respectively connected to the connecting rod 17 and the conduit 6;

[0082] A cavity 21 is formed on the elastic bellows. A one-way valve 22 and a pressure relief valve 23 are embedded on the side wall of the cavity 21. The output end of the pressure relief valve 23 is communicated with the pressure relief hole.

[0083] During the movement of the connecting rod 17, the connecting rod 17 drives the elastic bellows to expand and contract;

[0084] When the elastic bellows is stretched, the cavity 21 is in a negative pressure state, and the cavity 21 absorbs liquid from the conduit 6 through the one-way valve 22;

[0085] When the elastic bellows contracts, the liquid in the cavity 21 is squeezed and discharged into the pressure relief hole through the pressure relief valve 23. At this time, the liquid discharged from the pressure relief hole impacts the surface of the friction block 9, which can clean the surface of the friction block 9, so that the outer wall of the friction block 9 can directly contact the crushed soil, ensuring that there is sufficient friction between the friction block 9 and the crushed soil, which plays a role in ensuring that the friction block 9 can push the crushed soil away.

[0086] like Figure 5 As shown, a striking block 24 is fixedly mounted on the side wall of the connecting rod 17 .

[0087] At the moment when the connecting rod 17 is extended from the socket to the maximum, the connecting rod 17 drives the impact block 24 to impact the inner wall of the conduit 6, thereby transmitting the impact force to the impurities adhering to the surface of the friction block 9, causing the impurities to fall off, thereby assisting in cleaning the friction block 9.

[0088] like Figure 6 As shown, the bottom wall of the output end of the telescopic rod 5 is tapered, thereby facilitating the insertion of the telescopic rod 5 into the crushed soil.

[0089] like Figure 4 As shown, a guide groove 25 is provided on the connecting rod 17 , one end of the guide groove 25 located in the conduit 6 is communicated with the conduit 6 , and small holes 26 are evenly provided on the outer wall of the guide groove 25 .

[0090] The liquid medicine in the catheter 6 flows into the guide groove 25, and then the liquid in the guide groove 25 is discharged through the small hole 26. At the moment when the small hole 26 is out of contact with the edge of the socket, the liquid medicine discharged from the small hole 26 cleans out the impurities at the contact point between the connecting rod 17 and the catheter 6. When the connecting rod 17 is retracted into the catheter 6, the friction between the catheter 6 and the side wall of the socket is reduced, thereby protecting the catheter 6 and the side wall of the socket.

[0091] At the same time, when the small hole 26 moves to the outside of the conduit 6, the position of the small hole 26 is in a changing state, thereby increasing the probability of the liquid medicine discharged from the small hole 26 contacting the crushed soil, further improving the improvement effect.

[0092] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any person skilled in the art who, within the technical scope disclosed by the present invention, makes equivalent substitutions or modifications based on the technical solutions and improved concepts of the present invention shall be covered by the scope of protection of the present invention.
