Description

TECHNICAL FIELD

[0001] The utility model relates to saline-alkali soil improvement technology, concretely relates to a kind of conditioner injection device for saline-alkali soil improvement. BACKGROUND

[0002] In Xinjiang region, due to its unique geographical and climatic conditions, saline-alkali soil problem is more prominent. In the process of saline-alkali soil improvement, injection of conditioner is an effective means. However, the existing conditioner injection device faces many challenges in the actual application of Xinjiang saline-alkali soil.

[0003] However, the existing conditioner injection device has significant problems in actual application. These devices usually insert the injection device directly into the soil and use the holes on the device to inject the conditioner into the soil. Due to the soil characteristics of saline-alkali soil (such as high salt content, loose structure, etc.), the holes on the device are easily clogged by soil. This clogging not only reduces the injection efficiency of the conditioner, but also seriously affects the effect of soil improvement. In Xinjiang, a vast and widely distributed saline-alkali soil area, low injection efficiency of the conditioner will directly lead to slow progress of soil improvement, and even may affect local agricultural production and ecological environment.

[0004] Therefore, there is an urgent need for a new injection device that can effectively avoid soil clogging and improve the injection efficiency of the conditioner. SUMMARY

[0005] The purpose of the utility model is to provide a conditioner injection device for saline-alkali soil improvement, which effectively solves the problem of reduced injection efficiency of the conditioner caused by clogging of the holes on the injection device, and affects the effect of soil improvement.

[0006] To achieve the above purpose, the utility model provides the following technical scheme: a conditioner injection device for saline-alkali soil improvement, comprising a drill bit, a plug-in cylinder, a liquid guide pipe, a first driving component, a second driving component and a plurality of liquid guide components;

[0007] The drill bit is used to insert into the soil, and the drill bit is provided with a receiving cavity;

[0008] The bottom end of the plug-in cylinder is connected with the drill bit, and the bottom end of the plug-in cylinder is partially inserted into the receiving cavity. Multiple injection holes are uniformly provided on the side surface of the bottom end of the plug-in cylinder. The plug-in cylinder can move along the height direction of the plug-in cylinder relative to the drill bit;

[0009] The bottom end of the liquid guide pipe is partially arranged in the plug-in cylinder, and the liquid guide pipe is used to transport the conditioner;

[0010] Multiple liquid guiding components are used to guide the conditioning agent in the liquid guiding tube to the outside of the tube. Each liquid guiding component corresponds to a multiple injection hole. The liquid guiding component includes an outer tube and an inner tube. One end of the outer tube is connected to the inside of the liquid guiding tube. The inner side wall of the outer tube is slidably connected to the inner tube, and the axis of the inner tube is collinear with the axis of the corresponding injection hole of the inner tube.

[0011] The first driving component is used to drive the inner tubes of the multiple liquid guiding components to move along their respective axes.

[0012] The second drive unit is used to drive the drill bit to move along the height direction of the insert.

[0013] Furthermore, the first driving component includes a supporting frustum, on which multiple inclined grooves are formed, the number of which is the same as the number of liquid guiding components. Each of the multiple inclined grooves is slidably connected to a sliding rod, and each of the multiple sliding rods is fixedly connected to a sliding frame at its top. The top of each of the multiple sliding frames is fixedly connected to its adjacent inner tube, and the outer side of each of the multiple sliding frames is slidably connected to the same fixed frame. The outer side wall of the fixed frame is fixedly connected to the insert. A rotary drive assembly for driving the supporting frustum to rotate around its own axis is connected to one side of the supporting frustum.

[0014] Furthermore, the rotary drive assembly includes a rotary drive component A, which is fixedly mounted on a fixed frame. A drive gear is fixedly sleeved on the outside of the output shaft of the rotary drive component A. A driven gear meshes with one side of the drive gear, and the driven gear is fixedly sleeved on the outside of the bottom end of the supporting frustum.

[0015] Furthermore, the second driving component includes a screw and a threaded hole in the drill bit. One end of the screw is connected to a rotary drive component B for driving the screw to rotate about its own axis, and the outer wall of the bottom end of the screw is threadedly connected to the inner wall of the threaded hole.

[0016] Furthermore, the B rotary drive is the same as the A rotary drive. The output shaft of the A rotary drive is fixedly connected to the top of the screw, and the upper outer wall of the screw is rotatably connected to the insert.

[0017] Furthermore, the second driving component also includes a guide rod, the top end of which is fixedly connected to the insert, and a guide hole is provided on the insert, the inner wall of which is slidably connected to the outer wall of the guide rod.

[0018] Furthermore, a fixing ring is fixedly connected to the outer wall of the liquid guide tube, and the outer wall of the fixing ring is fixedly connected to the insert.

[0019] Furthermore, a sealing ring is fixedly installed on the inner wall of the end of the outer tube away from the liquid guide tube.

[0020] Compared with the prior art, the present invention provides a conditioner injection device for improving saline-alkali land soil. By setting up a tube and a drill bit, the injection hole on the tube is initially located in the receiving cavity of the drill bit, which effectively prevents soil from entering the injection hole and the inside of the tube during the insertion process, thereby avoiding the problem of the injection hole being blocked.

[0021] After the drill bit is inserted into the soil to a predetermined depth, the second drive component drives the drill bit to move downward relative to the insert, causing the injection hole to move out of the accommodating cavity. At the same time, the first drive component drives the inner tube in the liquid guiding component to move. After the injection hole moves out of the accommodating cavity, the inner tube extends out of the injection hole and approaches the soil, thereby facilitating the conditioner to be discharged from the liquid guiding tube, outer tube and inner tube into the soil, effectively improving the injection efficiency of the conditioner.

[0030] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0031] Please see Figures 1 to 3 A conditioner injection device for improving saline-alkali land soil includes:

[0032] Drill bit 100, which is used to insert into the soil, has a receiving cavity 110 on it;

[0033] The insert 200 is connected to the drill bit 100 at its bottom end, and the bottom part of the insert 200 is inserted into the receiving cavity 110. Multiple injection holes 210 are evenly opened on the side of the bottom end of the insert 200. The insert 200 can move relative to the drill bit 100 along the height direction of the insert 200.

[0034] The liquid guide tube 300 has its bottom end set inside the insert 200. The liquid guide tube 300 is used to deliver the conditioner. The top end of the liquid guide tube 300 can be connected to an external delivery system for delivering the conditioner. The delivery system can be a delivery pump. The conditioner is delivered into the liquid guide tube 300 through the external delivery system. This is prior art and will not be described in detail.

[0035] Multiple liquid guiding components 400 are used to guide the conditioner inside the liquid guiding tube 300 to the outside of the insert 200. The multiple liquid guiding components 400 correspond one-to-one with multiple injection holes 210. Each liquid guiding component 400 includes an outer tube 410 and an inner tube 420. One end of the outer tube 410 is connected to the inside of the liquid guiding tube 300. The inner sidewall of the outer tube 410 is slidably connected to the inner tube 420, and the axis of the inner tube 420 is collinear with the axis of the corresponding injection hole 210 of the inner tube 420.

[0036] The first driving component 500 is used to drive the inner tube 420 of the plurality of liquid guiding components 400 to move along their respective axes.

[0037] The second drive component 600 is used to drive the drill bit 100 to move along the height direction of the insert 200.

[0038] When improving saline-alkali soil, it is necessary to inject conditioners into the soil. However, existing injection devices, in order to inject conditioners into the soil to a certain depth, usually insert the injection device into the soil and inject the conditioner into the soil through the holes on the injection device to improve the soil. However, when the injection device is inserted into the soil, the holes on the injection device are easily blocked by the soil, making it difficult or impossible for the conditioner to be injected into the soil. This results in low injection efficiency of the conditioner and further low soil improvement efficiency.

[0039] To address this, this application incorporates an insert 200 and a drill bit 100. The drill bit 100 and insert 200 are inserted into the soil. Since the injection hole 210 on the insert 200 is located within the receiving cavity 110, soil cannot enter the injection hole 210 or the insert 200, preventing blockage of the injection hole 210. After the drill bit 100 is inserted to a predetermined depth in the soil, the second driving component 600 drives the drill bit 100 to move downwards relative to the insert 200, causing the injection hole 210 on the insert 200 to move out of the receiving cavity 110. At this time, the first driving component 500 simultaneously drives the inner tube 420 of the multiple liquid guiding components 400 to extend from the injection hole 210 to approach the soil. This facilitates the extraction of the conditioner from the liquid guiding tube 300, outer tube 410, and inner tube 420 into the soil, thereby avoiding the situation where the conditioner is difficult or impossible to inject into the soil due to soil blockage and effectively improving injection efficiency.

[0040] Please see Figure 1 , Figure 2 , Figure 4 and Figure 5 In one embodiment of the present invention, the first driving component 500 includes a supporting frustum 510, on which a plurality of inclined grooves 520 are provided. The number of inclined grooves 520 is the same as the number of liquid guiding components 400. Each of the plurality of inclined grooves 520 is slidably connected to a sliding rod 530. Each of the plurality of sliding rods 530 is fixedly connected to a sliding frame 540 at its top end. The top ends of the plurality of sliding frames 540 are respectively fixedly connected to their adjacent inner tubes 420. The outer side of the plurality of sliding frames 540 is slidably connected to the same fixed frame 550. The outer side wall of the fixed frame 550 is fixedly connected to the insert 200. A rotary driving component for driving the supporting frustum 510 to rotate around its own axis is connected to one side of the supporting frustum 510.

[0041] Specifically, the supporting frustum 510 is driven to rotate by the rotary drive assembly. Since the sliding frame 540 is slidably connected to the fixed frame 550, when the supporting frustum 510 rotates, the inner wall of the inclined groove 520 pushes the sliding rod 530. The sliding rod 530 drives the sliding frame 540 to move. The sliding frame 540 drives the inner tube 420 to move along the axis of the inner tube 420, so that the inner tube 420 extends out of the injection hole 210, thereby injecting the conditioner into the soil.

[0042] Please see Figure 4 In one embodiment of the present invention, the rotary drive assembly includes a rotary drive component 560, which is fixedly mounted on a fixed frame 550. A drive gear 570 is fixedly sleeved on the outside of the output shaft of the rotary drive component 560. A driven gear 580 meshes with one side of the drive gear 570, and the driven gear 580 is fixedly sleeved on the outside of the bottom end of the supporting frustum 510.

[0043] Specifically, the A rotary drive component 560 adopts a rotary cylinder or motor. The A rotary drive component 560 drives the drive gear 570 to rotate, the drive gear 570 drives the driven gear 580 to rotate, and the driven gear 580 drives the support frustum 510 to rotate, thereby realizing the rotation of the support frustum 510.

[0044] Please see Figure 1 and Figure 4 In one embodiment of the present invention, the second driving component 600 includes a screw 610 and a threaded hole 620 opened on the drill bit 100. One end of the screw 610 is connected to a B rotary driving component for driving the screw 610 to rotate around its own axis. The outer wall of the bottom end of the screw 610 is threadedly connected to the inner wall of the threaded hole 620.

[0045] B is the same as A, which is a rotary drive 560. The output shaft of A is fixedly connected to the top of the screw 610, and the upper outer wall of the screw 610 is rotatably connected to the insert 200.

[0046] The second driving component 600 also includes a guide rod 630, the top end of which is fixedly connected to the insert 200. The insert 200 has a guide hole 640, and the inner wall of the guide hole 640 is slidably connected to the outer wall of the guide rod 630.

[0047] Specifically, the screw 610 is driven to rotate by the B rotary drive component, and the guide rod 630 limits the movement of the drill bit 100. When the screw 610 rotates, the screw 610 drives the drill bit 100 to move downward. After the drill bit 100 moves, the injection hole 210 moves out of the accommodating cavity 110. After that, the inner tube 420 extends out of the injection hole 210.

[0048] Please see Figure 1 In one embodiment of this utility model, a fixing ring 700 is fixedly connected to the outer wall of the liquid guide tube 300. The outer wall of the fixing ring 700 is fixedly connected to the insert 200, and the liquid guide tube 300 is fixed and limited by the fixing ring 700.

[0049] In one embodiment of this utility model, a sealing ring is fixedly installed on the inner wall of the end of the outer tube 410 away from the liquid guide tube 300. The sealing ring seals the space between the outer tube 410 and the inner tube 420 to prevent the conditioner from leaking between the outer tube 410 and the inner tube 420.

[0050] In one embodiment of this utility model, a corresponding control unit can be set up for cooperative use. This control unit can be any type of controller connected to the electrical components in this application, thereby controlling the start-up and shutdown of each electrical component. This part is prior art. Here, a microcontroller can be provided as the control unit for demonstration. In this embodiment, the microcontroller is a typical embedded microcontroller unit, consisting of an arithmetic logic unit (ALU), a controller, a memory, input / output devices, etc., equivalent to a miniature computer. Compared with the general-purpose microprocessors used in personal computers, it emphasizes self-sufficiency (no external hardware required) and cost savings. Its biggest advantage is its small size, which can be placed inside the instrument, but it has small storage capacity, simple input / output interfaces, and low power consumption.

[0051] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
