Abstract
Description
Technical Field
[0001] The present application relates to the technical field of saline-alkali soil improvement devices, and specifically to a saline-alkali land improvement device. Background Art
[0002] Saline-alkali soil, a unique soil type widely distributed globally, poses a significant challenge to crop growth due to its high salt content. To effectively utilize this land resource, saline-alkali soil improvement has become a key research area in the agricultural sector. Currently, a variety of saline-alkali soil improvement devices have emerged on the market. Most of these devices utilize soil-breaking mechanisms to break up and plow the soil, aiming to physically improve soil structure, promote salt leaching, and thereby restore soil fertility.
[0003] The Chinese utility model patent with authorization announcement number CN220897123U discloses a saline-alkali soil improvement device. It opens a second socket inside the fixed frame and opens a first socket outside the support frame. The support plate can be embedded in the inside of the fixed frame, and the plug rod can be pulled out to separate the plug rod from the first socket and the second socket. Then the support frame is pulled out from the inside of the fixed frame, and the improved body can be disassembled as a whole for replacement or maintenance. The disassembly method saves time and effort and reduces the difficulty of disassembly. However, since the two fixed frames are symmetrically and fixedly connected to the device body, this design directly limits the types and size ranges of soil turning mechanisms that can be installed. In actual applications, the saline-alkali soil characteristics in different regions are different, and there are often different requirements for parameters such as the operating depth and width of the soil turning mechanism. Therefore, a soil turning mechanism of a single size is difficult to meet the diverse needs of soil improvement, limiting the application flexibility and wide range of the improvement device.
[0004] Therefore, the present application provides a saline-alkali land improvement device to solve the above problems. Utility Model Content
[0005] The present application provides a saline-alkali land improvement device, which aims to solve the problem proposed in the background technology that the two existing fixed frames are symmetrically fixedly connected to the device body, which results in the two fixed frames only being able to install soil-turning mechanisms of the same model and size, and cannot adapt to soil-turning mechanisms of different sizes, thereby reducing the applicability of the improvement device.
[0006] To achieve the above-mentioned objectives, the present application provides the following technical solutions: a saline-alkali land improvement device, comprising a device body, a push handle provided on the device body, a fixing frame symmetrically provided on one end of the device body near the push handle for mounting a plowing device, and a protective structure for protecting the plowing device;
[0007] To facilitate adjustment of the distance between the two fixed frames, allowing them to accommodate tilling devices of different lengths, the device body is equipped with an adjustment mechanism for driving the two fixed frames to move relative to or away from each other. This adjustment mechanism includes a guide frame fixed to the bottom of the device body, a bidirectional screw rotatably inserted into the guide frame, a slider symmetrically threaded onto the bidirectional screw and fixedly connected to the fixed frame, and a handwheel fixedly connected to one end of the bidirectional screw. To adjust the distance between the two fixed frames, the user first grasps the handwheel and applies a rotational force. Rotation of the handwheel drives the bidirectional screw within the guide frame. Because the two ends of the bidirectional screw have different thread directions, rotation of the screw causes the sliders on either side to move toward or away from each other. The slider is fixedly connected to the fixed frame, so the distance between the fixed frames also adjusts as the slider moves. When the desired distance is achieved, the user stops rotating the handwheel and locks the relevant components to prevent slippage. The tilling device can now be installed on the fixed frame and tilling operations can begin.
[0008] Preferably, the protective structure includes a protective cover mounted on the vertical rod of the device body at a position above the tilling device, and a hydraulic cylinder fixedly mounted on the device body for driving the protective cover to move up and down, with the output end of the hydraulic cylinder fixedly connected to the top of the protective cover. The design of the protective cover effectively protects the tilling device from damage by external debris during operation, thereby improving the durability and service life of the equipment. The presence of the protective cover also reduces the potential risk of injury to the operator due to flying debris, thereby improving safety during operation.
[0009] Preferably, to prevent soil from splashing during tillage, a retaining plate is hingedly connected to the end of the protective cover away from the device body. The addition of the retaining plate significantly improves the protective cover's splash-proof performance, effectively blocking soil splashed during tillage, keeping the work area clean and minimizing soil loss. Reducing soil splashing means reducing work interruptions due to soil cleanup, thereby improving overall work efficiency.
[0010] Preferably, to create grooves on the soil surface after plowing, thereby facilitating the collection of rainwater, a toothed plate for creating grooves in the soil is fixedly connected to the bottom of one end of the retaining plate, which is closest to the device body. The grooves formed on the soil surface by the toothed plate during plowing naturally guide rainwater to low-lying areas, thereby facilitating its collection and utilization. This is of great significance for improving farmland drainage, reducing soil erosion, and promoting crop growth.
[0011] Preferably, in order to improve the versatility of the improvement device, an improver spraying mechanism is added in the forward direction of the device body, and then the sprayed improver can be fully mixed with the soil through the tillage device: the device body is also provided with an improver spraying mechanism, and the improver spraying mechanism includes a material barrel provided at the end of the device body away from the pusher, a pipe provided on the device body and connected to the material barrel, and a plurality of nozzles provided on the pipe. By precisely spraying the improver, the soil structure, soil fertility, soil pH, etc. can be effectively improved, providing a more favorable soil environment for crop growth. The combined use of the improver spraying mechanism and the tillage device realizes the synchronous mixing of the improver and the soil, reduces the operation steps and costs, and improves the overall operation efficiency.
[0012] The adjustable structure design of this application allows users to easily adjust the distance between the two fixed frames, adapting to a variety of tillage devices of different models and lengths to meet diverse farming needs. Users can easily adjust the spacing of the fixed frames by simply turning the handwheel, without the need for specialized tools or complicated disassembly and installation procedures.

[0019] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.
[0020] This embodiment provides a saline-alkali land improvement device, such as Figure 1-4 As shown, the improved device includes a device body 1, a push handle 2 provided on the device body 1, a fixing frame 3 symmetrically provided at one end of the device body 1 close to the push handle 2 for mounting the tillage device, and a protective structure 4 for protecting the tillage device;
[0021] To facilitate adjustment of the distance between the two fixed frames 3 and to accommodate tillage devices of varying lengths, the device body 1 is equipped with an adjustment structure 5 for driving the two fixed frames 3 relative to or away from each other. This adjustment structure 5 comprises a guide frame 51 fixed to the bottom of the device body 1, a bidirectional screw 52 rotatably inserted into the guide frame 51, a slider 53 symmetrically threaded onto the bidirectional screw 52 and fixedly connected to the fixed frame 3, and a handwheel 54 fixedly connected to one end of the bidirectional screw 52. The design of the adjustment structure 5 allows users to easily adjust the distance between the two fixed frames 3, accommodating a variety of tillage devices of varying lengths and meeting diverse farming needs. Users can easily adjust the spacing between the fixed frames 3 by simply turning the handwheel 54, eliminating the need for specialized tools or complex disassembly and installation procedures. To adjust the distance between the two fixed frames 3, the user first grasps the handwheel 54 and applies a rotational force. The rotation of the handwheel 54 drives the bidirectional screw 52 to rotate within the guide frame 51. Because the two ends of the bidirectional screw 52 have different thread orientations, when the screw rotates, the sliders 53 on either side move toward or away from each other. The sliders 53 are fixedly connected to the fixed frame 3, so the fixed frame 3 also adjusts the spacing as the sliders 53 move. When the desired spacing is achieved, the user stops rotating the handwheel 54 and locks the relevant components to prevent slippage. The tilling device can now be installed on the fixed frame 3 and tillage operations can begin.
[0022] Specifically, the protective structure 4 comprises a protective cover 41 mounted on the vertical rod of the device body 1, corresponding to the position above the tilling device, and a hydraulic cylinder 42 fixed to the device body 1 to drive the protective cover 41 up and down. The output end of the hydraulic cylinder 42 is fixedly connected to the top of the protective cover 41. The design of the protective cover 41 effectively protects the tilling device from damage by external debris during operation, improving the durability and service life of the device. The presence of the protective cover 41 also reduces the potential risk of injury to the operator from flying debris, thereby improving safety during operation. Driven by the hydraulic cylinder 42, the user can easily adjust the protective cover 41 to suit different operating needs and scenarios. When the device begins operation, the user first activates the hydraulic cylinder 42 through the control system. Upon receiving the command, the hydraulic cylinder 42 begins operation, and its output end pushes the protective cover 41 downward along the vertical rod until it completely covers the tilling device and its mounting area. At this point, the protective cover 41 is in a protective state, effectively blocking external debris from damaging the tilling device. During operation, if the tillage device needs to be adjusted or other maintenance work needs to be performed, the user can activate the hydraulic cylinder 42 again through the control system, causing it to move in the opposite direction and drive the protective cover 41 to slide upward along the vertical rod to the appropriate position or fully open state. In this way, the user can easily access the tillage device for operation.
[0023] Furthermore, to prevent soil from splashing during tillage, a retaining plate 411 is hingedly connected to the end of the protective cover 41 facing away from the main body 1. The inclusion of retaining plate 411 significantly enhances the protective cover's splash-proof performance, effectively blocking soil splashed during tillage, keeping the work area clean and minimizing soil loss. Reducing soil splash means less interruption time for cleaning up splashed soil, thereby improving overall operational efficiency. The adjustable angle of retaining plate 411 allows the equipment to adapt to varying terrain and tillage conditions, enhancing its versatility and flexibility. During tillage operations, as the tillage device activates and operates, soil is stirred up and potentially splashed. In this situation, the protective cover 41 and retaining plate 411 work together: the protective cover 41 acts as the primary barrier to block most of the splashing, while the retaining plate 411 provides additional protection against splashed soil that may have been missed by the edges of the protective cover 41. When soil strikes retaining plate 411, its kinetic energy is converted into rotational or rebound energy, preventing further splashing beyond the protective area. During the entire process, the combined design of the protective cover 41 and the earth retaining plate 411 ensures smooth plowing and a clean environment in the working area.
[0024] Furthermore, to create grooves on the soil surface after plowing, thereby facilitating the collection of rainwater, a tooth plate 4111 for creating grooves in the soil is fixedly connected to the bottom of one end of the retaining plate 411, near the device body 1. The grooves formed on the soil surface by the tooth plate 4111 during the plowing process can naturally guide rainwater to low-lying areas, thereby facilitating the collection and utilization of rainwater. This is of great significance for improving farmland drainage, reducing soil erosion, and promoting crop growth. The formation of grooves also increases the roughness and air permeability of the soil surface, which is beneficial for the activity of soil microorganisms and the respiration of plant roots, thereby improving soil quality. During the plowing operation, as the plowing device penetrates and moves, the retaining plate 411 and the tooth plate 4111 at its bottom are pushed forward. The tooth-like protrusions of the tooth plate 4111 cut into the soil and form grooves. These grooves not only help to block splashing soil, but also leave visible traces on the soil surface, guiding the flow of rainwater. At the same time, the main working components of the tillage mechanism continue to plow and break up the soil, complementing the furrowing action of tooth plates 4111, thus completing the dual tasks of tillage and furrowing. Throughout this process, the combined design of protective cover 41 and retaining plate 411 ensures operational safety and efficiency, while the addition of tooth plates 4111 further enhances the versatility and practicality of the equipment.
[0025] Furthermore, to enhance the versatility of the improvement device, an improver spraying mechanism 6 is installed in the forward direction of the device body 1. The sprayed improver can then be thoroughly mixed with the soil through the tillage device: the device body 1 is also provided with an improver spraying mechanism 6, which includes a material barrel 61 disposed at the end of the device body 1 away from the push handle 2, a pipe 62 disposed on the device body 1 and connected to the material barrel 61, and a plurality of nozzles 63 disposed on the pipe 62. By precisely spraying the improver, soil structure, soil fertility, and soil pH can be effectively improved, thereby providing a more favorable soil environment for crop growth. The application of improvers can enhance crop resistance, increase yield and quality, and thus increase farmers' economic benefits. The combination of the improver spraying mechanism 6 and the tillage device achieves synchronous mixing of the improver and soil, reduces operation steps and costs, and improves overall operation efficiency. Before the tillage operation begins, an appropriate amount of improver is added to the material barrel 61 and sealed. As the device body 1 advances and the tillage mechanism activates, the amendment is delivered to each nozzle 63 via pipes 62. As the tillage mechanism plows the soil, the nozzles 63 evenly spray the amendment onto the soil surface. Thanks to the tillage mechanism's plowing action, the amendment sprayed onto the soil surface quickly mixes evenly with the soil, achieving the desired improvement effect. Throughout this process, the operator simply controls the advancement speed of the device body 1 and the amount of amendment sprayed to easily complete the operation.
[0026] The above is only a preferred specific implementation method of the present application, but the scope of protection of the present application is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and concept of the present application within the technical scope disclosed in the present application, and they should be covered by the scope of protection of the present application.
