Description

Technical Field

[0001] This utility model relates to the field of soil turning technology, and more specifically, it relates to a soil turning device for seedling planting. Background Technology

[0002] Existing soil-turning devices for seedling planting generally suffer from a serious problem of ineffective soil conditioning after loosening. Traditional devices mostly only have basic soil-turning and loosening functions, using simple plows, harrows, or shovels for soil treatment. While the mechanical action can break up the surface crust, it is difficult to achieve fine-tuning and optimization of the soil's internal structure. If the loosened soil lacks further conditioning, it will lead to several adverse consequences. First, the soil particles will be of varying sizes and densities, creating areas of both compaction and looseness, making it difficult for seedling roots to distribute and grow evenly. Second, the unconditioned soil may contain insufficiently broken clods and compacted layers; these obstacles will hinder root extension and water penetration, affecting seedling survival rate and growth rate.

[0003] The combing frame in existing soil turning devices generally suffers from the technical defect of inconvenient position adjustment. Most traditional devices adopt a fixed or simple adjustable design, and the adjustment method mainly relies on bolt fixing or pin insertion, which has obvious operational limitations. In actual working environments, soil conditions are often complex and variable, and the soil texture, density and moisture conditions of different areas vary significantly. Frequent adjustments to the combing depth are required to achieve the ideal effect. The whole process is cumbersome and time-consuming. In large-scale operations, this inefficient adjustment method greatly delays the work progress and reduces the work efficiency. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] In view of the problems existing in the prior art, this utility model provides a seedling planting and soil turning device to solve the technical problems mentioned in the background art, such as the lack of soil combing after loosening and the inconvenience of adjusting the position of the combing frame.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a seedling planting and soil turning device, comprising a main frame, a soil sorting mechanism, a position fixing mechanism, and a fixing auxiliary mechanism. The soil sorting mechanism includes a support frame, a rotating rod, a driving plate, a clamping pipe, a clamping rod, and a sorting frame. The support frame is symmetrically installed on one end face of the main frame. The driving plate is installed on the driving rod. The clamping rod is installed on the driving plate. The clamping pipe is fixedly installed on the support frame. The clamping rod can extend into the clamping pipe to cooperate with rotation or clamping. The sorting frame is installed on the rotating rod. The position fixing mechanism includes an annular groove, a counter-tension spring rod, a spinning block, a rotating sleeve, and a spinning plate. The annular groove is provided on the side wall of the clamping rod. The counter-tension spring rod is laterally slidably installed on the side wall of the clamping pipe. The spinning block is installed at one end of the counter-tension spring rod. The rotating sleeve is limited to rotate and installed on the outer wall of the clamping pipe. The spinning plate is installed on the rotating sleeve. The inner wall of the spinning plate presses against the pressing block, causing the spring rod to extend into the annular groove, thus fixing the clamping rod inside the clamping pipe.

[0008] The present invention is further configured such that the fixing auxiliary mechanism includes a bottom fixing ring, a spring-loaded pin, a support ring, and a spring-loaded groove. The bottom fixing ring is installed on the outer wall of the clamping tube. Multiple sets of spring-loaded pins are arranged in a ring on the support ring. The support ring is installed at the bottom end of the rotating sleeve. Multiple sets of spring-loaded grooves are opened in a ring at the bottom end of the support ring. One end of the spring-loaded pin can extend into the spring-loaded groove step by step, so that the support ring and the rotating sleeve can rotate stably.

[0009] The present invention is further configured such that bottom wheels are symmetrically installed at one bottom end of the main frame, which facilitates the movement and turning of the device, reduces the dragging burden, and improves the mobility of operation.

[0010] The present invention is further configured such that a soil loosening frame is installed at the bottom end of the main frame, and multiple sets of soil loosening frames are provided. The soil loosening frame loosens the soil surface initially, breaks the hard crust of the ground, and creates conditions for subsequent deep sorting.

[0011] The present invention is further configured such that a hydraulic cylinder is rotatably mounted on the top end of the main frame, and a rotating plate is rotatably mounted on one end of the hydraulic cylinder. The hydraulic cylinder is rotatably mounted on the top of the main frame to provide precise lifting power and control the working depth of the combing rack.

[0012] The present invention is further configured such that one end of the rotating plate is rotatably connected to the rotating rod, and the rotating plate can cause the rotating rod and the driving plate to rotate relative to the support frame. The rotating plate converts the pushing and pulling motion of the hydraulic cylinder into the swinging motion of the rotating rod.

[0013] The present invention is further configured such that a connecting plate is installed at the bottom end of the side wall of the clamping tube, and the connecting plate is fixedly installed on one end face of the support frame, thereby ensuring a firm connection between the clamping tube and the support frame.

[0014] The present invention is further configured such that a connecting frame is installed on one side of the main frame, and the connecting frame is connected in cooperation with an external driving device. The connecting frame is used to connect in cooperation with an external driving device (such as a tractor) to realize power transmission and overall movement control.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a seedling planting and soil turning device, which has the following beneficial effects:

[0017] This invention features a soil combing mechanism that, through the coordinated action of a support frame, a rotating rod, and a combing frame, achieves fine combing of the loosened soil. The combing frame can penetrate deep into the soil, improving its structure, breaking up clods and compacted layers, and creating a suitable soil environment for seedling root growth. The design of the locking rotating rod and locking connecting pipe ensures that the combing frame maintains a stable working position during operation while also allowing for flexible adjustments. This solves the technical defect of traditional devices that lack combing after loosening the soil, providing seedlings with a uniform, breathable, and well-water-retaining growth foundation.

[0018] This utility model is equipped with a position fixing mechanism, which adopts a structural design of annular groove, anti-tension spring rod and spinning assembly. It realizes the rapid and accurate adjustment and firm locking of the position of the combing frame. The rotation operation of the rotating sleeve and the spinning plate causes the anti-tension spring rod to move laterally and accurately insert into the annular groove of the locking rod to form a reliable locking effect. This overcomes the problem of inconvenient adjustment of the position of the combing frame in traditional devices and greatly improves the work efficiency.

[0019] This utility model incorporates a fixing auxiliary mechanism. Through the ingenious cooperation of the bottom fixing ring, spring-loaded pin, support ring, and spring-loaded groove, it provides more precise control and feedback for the position fixing mechanism. Multiple sets of ring-shaped spring-loaded pins and spring-loaded grooves cooperate in stages, making the rotation operation of the rotating sleeve have clear stages. The operator can clearly judge the degree of rotation by touch, which not only improves the locking accuracy and reduces the difficulty of operation, but also prevents the accidental rotation of the rotating sleeve, enhancing the reliability and safety of the entire locking system.

[0029] Please see Figures 1-5A soil-turning device for seedling planting includes a main frame 1, a soil-sorting mechanism, a position-fixing mechanism, and a fixing auxiliary mechanism. The soil-sorting mechanism includes a support frame 2, a rotating rod 3, a driving plate 4, a clamping pipe 5, a clamping rotating rod 6, and a sorting frame 7. The support frame 2 is symmetrically installed on one end face of the main frame 1. The driving plate 4 is installed on the driving rod. The clamping rotating rod 6 is installed on the driving plate 4. The clamping pipe 5 is fixedly installed on the support frame 2. The clamping rotating rod 6 can extend into the clamping pipe 5 to cooperate in rotation or clamping. The sorting frame 7 is installed on the rotating rod 3. The positioning fixing mechanism includes an annular groove 8, a counter-tension spring rod 9, a spinning block 10, a rotating sleeve 11, and a spinning plate 12. The annular groove 8 is set on the side wall of the locking rod 6. The counter-tension spring rod 9 is laterally slidably installed on the side wall of the locking tube 5. The spinning block 10 is installed at one end of the counter-tension spring rod 9. The rotating sleeve 11 is limited to rotate and installed on the outer wall of the locking tube 5. The spinning plate 12 is installed on the rotating sleeve 11. The inner wall of the spinning plate 12 presses against the pressing block, causing the spring rod to extend into the annular groove 8, thus fixing the locking rod 6 inside the locking tube 5.

[0030] In this embodiment, the soil sorting mechanism is first fixed to the end face of the main frame 1 by the support frame 2, forming a stable working foundation. During operation, the hydraulic cylinder 19 pushes the rotating plate 20, which drives the rotating rod 3 and the driving plate 4 to rotate around the support frame 2. The sorting frame 7 installed on the rotating rod 3 then descends to the soil surface to perform soil sorting operations. The locking rod 6 on the driving plate 4 extends into the locking pipe 5 on the support frame 2 to form a rotating connection, ensuring stability during the rotation process. During the descent, the sorting frame 7 can penetrate deep into the soil to loosen and sort the soil, break up the hard crust, and improve the soil's permeability and water retention capacity, thus preparing the soil for seedling planting. The soil combing mechanism creates favorable conditions for planting. When the soil combing mechanism is in the appropriate position, the positioning and fixing mechanism plays its role. After the combing frame 7 descends to the predetermined depth, it is necessary to temporarily fix the position of the combing frame 7. At this time, the operator rotates the rotating sleeve 11 on the outer wall of the clamping tube 5, which drives the spinning plate 12 to press the spinning block 10 on the anti-tension spring rod 9 inward. Under the pressure, the anti-tension spring rod 9 moves laterally, and one end of it extends into the annular groove 8 on the side wall of the clamping rod 6, which firmly locks the clamping rod 6 in the clamping tube 5 to prevent it from moving accidentally. This allows the combing frame 7 to be kept in a specific position for stable operation, avoiding positional deviation caused by vibration or external force, and ensuring the combing effect.

[0031] The fixing auxiliary mechanism includes a bottom fixing ring 13, a spring-loaded pin 14, a support ring 15, and a spring-loaded groove 16. The bottom fixing ring 13 is installed on the outer wall of the clamping tube 5. Multiple sets of spring-loaded pins 14 are arranged in a ring on the support ring 15. The support ring 15 is installed at the bottom end of the rotating sleeve 11. Multiple sets of spring-loaded grooves 16 are opened in a ring at the bottom end of the support ring 15. One end of the spring-loaded pin 14 can extend into the spring-loaded groove 16 step by step, so that the support ring 15 and the rotating sleeve 11 can rotate stably.

[0032] In this embodiment, the bottom retaining ring 13 on the outer wall of the retaining tube 5 and the support ring 15 at the bottom of the rotating sleeve 11 form a mating relationship. The bottom of the support ring 15 is provided with multiple annularly distributed spring-loaded grooves 16, and the bottom retaining ring 13 is provided with corresponding spring-loaded pins 14. When the rotating sleeve 11 rotates, the spring-loaded pins 14 can extend into the spring-loaded grooves 16 step by step, so that the rotation process has obvious stages. This not only allows the operator to clearly perceive the degree of rotation through touch, avoiding excessive or insufficient rotation, but also prevents the rotating sleeve 11 from rotating on its own due to vibration, maintaining the stability of the locked state and improving the reliability of the entire fixing system.

[0033] Please see Figures 1-5 As a supplementary embodiment of a seedling planting soil turning device with soil sorting mechanism, position fixing mechanism and fixing auxiliary mechanism: a bottom wheel 17 is symmetrically installed at one bottom end of the main frame 1, a soil loosening frame 18 is installed at the bottom end of the main frame 1 and multiple sets of soil loosening frames 18 are provided, a hydraulic cylinder 19 is rotatably installed at the top end of the main frame 1, and a rotating plate 20 is rotatably installed at one end of the hydraulic cylinder 19. One end of the rotating plate 20 is rotatably connected to the rotating rod 3. The rotating plate 20 can make the rotating rod 3 and the driving plate 4 rotate relative to the support frame 2. A connecting plate 21 is installed at the bottom end of the side wall of the clamping pipe 5 and is fixedly installed on one end face of the support frame 2. A connecting frame 22 is installed on one side of the main frame 1 and is connected to an external driving device.

[0034] More specifically, the top hydraulic cylinder 19 is activated, pushing the rotating plate 20, causing the rotating rod 3 to lower the combing frame 7 into the soil. At this time, the locking rod 6 extends into the locking tube 5, forming a rotating connection. After the combing frame 7 reaches the appropriate depth, the operator rotates the rotating sleeve 11, pressing the anti-tension spring rod 9 through the spinning plate 12, causing it to extend into the annular groove 8 of the locking rod 6, fixing the position of the combing frame 7. During the rotation, the spring top pin 14 extends into the spring top groove 16 step by step, providing operational feedback and stable support. After the position is fixed, the drive equipment moves the entire device forward. The combing frame 7 fully combs the soil at the fixed depth, while the loosening frame 18 cooperates to perform surface treatment, comprehensively improving the soil structure. When it is necessary to adjust the combing depth, the rotating sleeve 11 is rotated in the opposite direction to release the locking of the anti-tension spring rod 9 and the annular groove 8. Then, the height of the combing frame 7 is readjusted through the hydraulic cylinder 19, and the position is locked again to continue working. After the operation is completed, the lock is released, the hydraulic cylinder 19 is retracted, and the combing frame 7 rises away from the soil. The device can then be moved to the next working area or returned to the storage point.

[0035] In summary, during the use or operation of the overall equipment: When the soil sorting mechanism is required to operate, it is first fixed to the end face of the main frame 1 by the support frame 2, forming a stable working foundation. During operation, the hydraulic cylinder 19 pushes the rotating plate 20, which drives the rotating rod 3 and the driving plate 4 to rotate around the support frame 2. The sorting frame 7 installed on the rotating rod 3 then descends to the soil surface to perform soil sorting operations. The locking rod 6 on the driving plate 4 extends into the locking pipe 5 on the support frame 2 to form a rotating connection, ensuring stability during the rotation process. During the descent, the sorting frame 7 can penetrate deep into the soil to loosen and sort the soil, break up the hard crust, improve soil permeability and water retention capacity, and create favorable conditions for seedling planting.

[0036] When the position fixing mechanism is required, it plays a role when the soil combing mechanism is in the appropriate position. After the combing frame 7 descends to the predetermined depth, it is necessary to temporarily fix the position of the combing frame 7. At this time, the operator rotates the rotating sleeve 11 on the outer wall of the clamping pipe 5, which drives the spinning plate 12 to press the spinning block 10 on the anti-tension spring rod 9 inward. Under the pressure, the anti-tension spring rod 9 moves laterally, and one end of it extends into the annular groove 8 on the side wall of the clamping rod 6, which firmly locks the clamping rod 6 in the clamping pipe 5 to prevent it from moving accidentally. This allows the combing frame 7 to be kept in a specific position for stable operation, avoiding positional deviation caused by vibration or external force, and ensuring the combing effect.

[0037] When the auxiliary mechanism needs to be fixed during operation, the bottom fixing ring 13 on the outer wall of the clamping pipe 5 and the support ring 15 at the bottom of the rotating sleeve 11 form a cooperative relationship. The bottom of the support ring 15 is provided with multiple annularly distributed spring-loaded grooves 16, and the bottom fixing ring 13 is provided with corresponding spring-loaded pins 14. When the rotating sleeve 11 rotates, the spring-loaded pins 14 can extend into the spring-loaded grooves 16 step by step, so that the rotation process has a clear sense of stages. This not only allows the operator to clearly perceive the degree of rotation through touch, avoiding excessive or insufficient rotation, but also prevents the rotating sleeve 11 from rotating on its own due to vibration, maintaining the stability of the locked state and improving the reliability of the entire fixing system.

[0038] Start the top hydraulic cylinder 19 to push the rotating plate 20, causing the rotating rod 3 to drive the combing frame 7 down into the soil. At this time, the locking rod 6 extends into the locking tube 5 to form a rotating connection. After the combing frame 7 reaches the appropriate depth, the operator rotates the rotating sleeve 11, which presses the anti-tension spring rod 9 through the spinning plate 12, causing it to extend into the annular groove 8 of the locking rod 6 and fix the position of the combing frame 7. During the rotation, the spring top pin 14 extends into the spring top groove 16 step by step to provide operational feedback and stable support. After the position is fixed, the drive equipment moves the entire device forward. The combing frame 7 fully combs the soil at the fixed depth. At the same time, the loosening frame 18 cooperates to perform surface treatment, comprehensively improving the soil structure. When it is necessary to adjust the combing depth, rotate the rotating sleeve 11 in the opposite direction to release the locking of the anti-tension spring rod 9 and the annular groove 8. Then, readjust the height of the combing frame 7 through the hydraulic cylinder 19, lock the position again, and continue working. After the operation is completed, release the lock, retract the hydraulic cylinder 19, and make the combing frame 7 rise away from the soil. The device can then be moved to the next working area or returned to the storage point.

[0039] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
