Description

Technical Field

[0001] This invention relates to the field of agricultural machinery technology, specifically to a rotary lime-based composite material feeding device for improving acidic soils in agriculture. Background Technology

[0002] In agricultural production, acidic soils, due to their low pH value, can easily lead to hindered root development and reduced nutrient absorption efficiency in crops. It is necessary to adjust the soil pH by applying lime-based composite materials. However, existing soil improvement and tillage equipment has obvious technical defects and cannot meet the needs of efficient and integrated operations.

[0003] Traditional tillage and compaction devices can only loosen the soil and cannot simultaneously apply lime-based composite materials. The soil must first be loosened by tillage equipment, and then the amendment materials must be applied separately using a fertilizer spreader or manually. This not only increases the number of work procedures and time costs, but also easily leads to uneven soil pH adjustment due to soil surface compaction and uneven distribution of amendment materials after tillage, which affects crop growth.

[0004] The existing integrated equipment for dispensing lime-based composite materials has an unreasonable design, with most using simple fixed pipes for feeding and lacking mixing functions. This easily leads to material clumping and clogging of the dispensing port, resulting in unstable dispensing rates. At the same time, the dispensing position and the tilling depth cannot be adjusted in conjunction. When dealing with different types of acidic soils such as clay and sand, if the tilling is too shallow, the improved material will only remain on the surface and will not be able to mix fully with the deeper acidic soil. If the tilling is too deep, the material will be easily buried and will not be able to quickly exert its regulating effect, thus limiting its adaptability. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a rotary lime-based composite material feeding device for improving acidic soils in agriculture.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a rotary lime-based composite material feeding device for improving acidic soil in agriculture, comprising a connecting beam, a connecting support fixedly installed at the top of the connecting beam, the connecting support being used to connect to a tillage cart, the tillage cart driving the entire device to move and till the cultivated land, an adjusting rod movably installed below the connecting beam, the adjusting rod comprising an adjusting rod one, an adjusting cylinder fixedly installed on the adjusting rod one, an adjusting ring movably installed on the adjusting cylinder, a curved plow rod movably installed on the adjusting ring, and a plow head fixedly installed at the bottom of the curved plow rod, the device tilling the cultivated land through the plow head when moving; Side plates are fixedly installed on both sides of the connecting beam. An adjustment mechanism is provided on the side plate. The adjustment mechanism cooperates with the adjustment rod to adjust the overall position of the curved plow and the plow head, thereby changing the angle and depth at which the whole device acts on the cultivated land. The rear end of the connecting beam is movably mounted with a connecting rod 1 via a groove and a spherical block, allowing the connecting rod 1 to rotate at multiple angles on the connecting beam. A guard plate is fixedly mounted on the connecting rod 1. The guard plate is located at the rear end of the curved plow and is adapted to the curved plow. The curved plow is used to block the turned soil. An adjusting block is fixedly installed on the guard plate.

[0009] Preferably, the mounting cylinder has several slots, and a mounting ring is movably mounted on the slots and the mounting cylinder. The inner ring of the mounting ring has a telescopic groove, and a locking block is mounted on the telescopic groove by a spring. A toggle plate is fixedly mounted on the locking block. By pressing the toggle plate, the locking block moves within the telescopic groove, thereby engaging or disengaging the locking block from the slot. The engagement of the locking block and the locking slot allows the mounting ring to be positioned on the mounting cylinder, determining the position of the plowshare and the plow head, and setting the spacing for all plow heads.

[0010] Preferably, a connecting rod two is fixedly installed at the top end of the curved plow rod, a connecting groove is provided at the top end of the mounting ring, the connecting rod two is placed in the connecting groove, a spring one is fixedly installed in the connecting groove, and the spring one is fixedly connected to the connecting groove; The spring and connecting groove position the plow rod on the mounting ring and provide the amount of movement for the plow rod to move in the slot.

[0011] Preferably, the adjusting block has a movable slot, one side of the second adjusting mechanism is engaged in the movable slot, and the other side of the second adjusting mechanism is installed on the plow rod. The second adjusting mechanism provides movement for the plow rod and the adjusting block.

[0012] Preferably, the second adjustment mechanism is a parallelogram composed of two adjustment rods four and two adjustment rods five. The adjustment rods five are telescopic rods that can extend and retract. The adjustment rods four closer to the adjustment block are engaged in the movable slots, and the adjustment rods four closer to the plow rod are connected to the plow rod. A pull rod is also fixedly installed on the adjustment rod four near the adjustment block. Pulling the pull rod separates the adjustment rod four from the movable slot.

[0013] Preferably, the adjusting rod four and the adjusting rod five are connected by a rotating shaft and a connecting ring. The rotating shaft is rotatably connected to the connecting ring and is connected to both the adjusting rod four and the adjusting rod five, so that the adjusting rod four and the adjusting rod five are rotatably connected, thereby allowing the parallelogram to change shape.

[0014] Preferably, an adjustment assembly is installed on the adjustment rod four. The adjustment assembly includes a mounting block one, a spring two, and a mounting block two. The mounting block one is fixedly connected to the plow rod, the spring two is fixedly connected to the mounting block one and the mounting block two, and the mounting block two is fixedly connected to the adjustment rod four.

[0015] Preferably, a conveying pipe is fixedly installed on one side of the upper end of the installation cylinder to convey the composite lime-based composite material into the installation cylinder. An agitator is installed inside the installation cylinder, and the lime-based composite material is stirred and mixed by the agitator and pushed to move within the installation cylinder. A discharge port is provided at the bottom of the installation cylinder to discharge the lime-based composite material and improve the acidity of the cultivated land.

[0016] Compared with the prior art, the present invention provides a rotary lime-based composite material dispensing device for improving acidic soils in agriculture, which has the following beneficial effects: 1. This rotary lime-based composite material feeding device for improving acidic soil in agriculture is universally connected to the tillage vehicle via a connecting support column, eliminating the need for a separate power unit, thus reducing equipment costs. It integrates tillage, soil retention, leveling, and splash prevention, reducing subsequent land treatment processes. The second adjustment mechanism can offset the impact of soil on the plow head and curved plow handle, extending the service life of core components.

[0017] 2. This rotary lime-based composite material feeding device for improving acidic soil in agriculture has multiple bent clamping grooves that provide multiple adjustment options. The tillage depth can be flexibly set according to the soil hardness to adapt to different farmland needs. The bent clamping groove design can effectively prevent the adjustment rod from loosening during operation, avoid sudden changes in tillage depth, and ensure consistent operation.

[0018] 3. This rotary lime-based composite material feeding device for improving acidic soil in agriculture features a telescopic and rotary structure that solves the problem of rigid interference between components during adjustment, making operation easier and reducing the intensity of manual adjustment. Through the rotational support of the round rod, the plow head can achieve a larger tilt angle, making it suitable for operations on uneven farmland such as slopes and depressions.

[0019] 4. This rotary lime-based composite material feeding device for improving acidic soil in agriculture can flexibly adjust the plow spacing according to the crop row spacing, avoiding damage to crop roots or waste of arable land space during plowing. The spacing can be adjusted simply by pressing, pushing, and releasing the actuating plate, without the need for tools, thus improving work efficiency.

[0020] 5. This rotary lime-based composite material feeding device for improving acidic soil in agriculture has a spring that effectively absorbs the impact force of obstacles, reduces the probability of damage to the plow rod and plow head, and reduces maintenance costs. The spring continuously provides clamping force to prevent the plow rod from shaking during operation, ensuring a neat plowing trajectory and improving the quality of cultivated land.

[0021] 6. This rotary lime-based composite material feeding device for improving acidic soil in agriculture can automatically adapt the plow to the terrain even if there are small undulations on the surface of the cultivated land. This avoids missed plowing or excessive plowing. The movable slot limits the movement of the adjustment mechanism two, preventing the plow rod from shifting laterally, ensuring that the plowing trajectory is parallel and improving the flatness of the cultivated land.

[0022] 7. This rotary lime-based composite material feeding device for improving acidic soil in agriculture features a parallelogram structure with a telescopic rod design, enabling multi-directional buffering that is more comprehensive than single spring buffering. It can cope with complex soil resistance changes. The pull rod design allows for tool-free disassembly of the adjustment mechanism, facilitating component replacement or cleaning and reducing maintenance difficulty.

[0023] 8. This rotary lime-based composite material feeding device for improving acidic soil in agriculture eliminates angular limitations between components through a rotary connection, allowing the adjustment mechanism two to adapt to a wider range of relative position changes, further improving the adaptability of the plow head to complex terrain. The rotational cooperation between the shaft and the connecting ring reduces sliding friction between components, extending the service life of the adjustment rods four and five.

[0024] 9. This rotary lime-based composite material feeding device for improving acidic soil in agriculture features a double buffer design that significantly reduces the impact of obstacles on the plow head and curved plow handle. It is especially suitable for farmland with many stones, reducing the risk of component breakage and deformation. The elastic restoring force of the second spring allows the curved plow handle to quickly return to its original position after passing over obstacles, preventing the plow head from deviating from the set tillage depth for a long time and ensuring continuous operation.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Example 1, please refer to Figures 1-6A rotary lime-based composite material feeding device for improving acidic soil in agriculture includes a connecting beam 10. A connecting support column 11 is fixedly installed at the top of the connecting beam 10. The connecting support column 11 is used to connect to a tillage vehicle. The tillage vehicle drives the entire device to move and till the cultivated land. An adjusting rod is movably installed below the connecting beam 10. The adjusting rod includes an adjusting rod 16. An installation cylinder 19 is fixedly installed on the adjusting rod 16. An installation ring 20 is movably installed on the installation cylinder 19. A curved plow rod 17 is movably installed on the installation ring 20. A plow head 18 is fixedly installed at the bottom of the curved plow rod 17. When the device moves, the plow head 18 tills the cultivated land. Both sides of the connecting beam 10 are fixedly installed with side plates 13. An adjustment mechanism is provided on the side plates 13. The adjustment mechanism and the adjustment rod are used to adjust the overall position of the curved plow rod 17 and the plow head 18, thereby changing the angle and depth of the overall device acting on the cultivated land. The rear end of the connecting beam 10 is movably mounted with a connecting rod 12 via a groove and a spherical block, allowing the connecting rod 12 to rotate at multiple angles on the connecting beam 10. A guard plate 14 is fixedly mounted on the connecting rod 12. The guard plate 14 is located at the rear end of the curved plow rod 17 and is adapted to the curved plow rod 17. The curved plow rod 17 is used to block the turned soil. An adjusting block 15 is fixedly installed on the guard plate 14. An adjusting mechanism 36 is provided between the adjusting block 15 and the curved plow rod 17. When the plow head 18 acts on the cultivated land, the plow head 18 interacts with the soil, thereby acting on the adjusting mechanism 36. The adjusting mechanism 36 provides movement variables for the curved plow rod 17 and the plow head 18, making it easier for the plow head 18 to act on the cultivated land. A cloth strip 34 is fixedly installed at the bottom of the guard plate 14. The adjusting block 34 is used to level the plowed farmland and prevent soil from splashing.

[0029] The device is connected to a tillage vehicle via a top connecting pillar 11. The tillage vehicle provides the power to move the entire device in the tillage field. The core tillage component is the plow head 18, which is fixed to the curved plow handle 17 from the bottom and inserts into the tillage field as the device moves to turn the soil.

[0030] The connecting beam 10 is made up of side plates 13 on both sides, which are equipped with an adjustment mechanism and an adjustment rod below. The overall position of the plow rod 17 and the plow head 18 can be changed, thereby adjusting the turning angle and depth.

[0031] The connecting beam 10 is equipped with a connecting rod 12 that is movably mounted at the rear end via a groove and a spherical block, allowing it to rotate at multiple angles. The guard plate 14 on the beam is located at the rear end of the curved plow rod 17 and can prevent the turned soil from scattering. At the same time, the adjusting block 15 on the guard plate 14 is provided with an adjusting mechanism 36 between it and the curved plow rod 17. When the plow head 18 interacts with the soil, the adjusting mechanism 36 can provide a movement variable to prevent the plow head 18 from being damaged due to excessive soil resistance.

[0032] Example 2, based on Example 1, please refer to... Figure 2 The first adjustment mechanism includes a slide groove 22, which is formed on the side plate 13. Several engagement grooves 23 are formed below the slide groove 22. The engagement grooves 23 are bent. An adjustment rod 24 is movably installed in the slide groove 22 and the engagement grooves 23. The adjustment rod 24 is fixedly connected to the first adjustment rod 16. The angle of the first adjustment rod 16 on the connecting beam 10 is changed by the engagement of the second adjustment rod 24 in the engagement grooves 23.

[0033] The adjusting rod 24 is moved up and down along the slide groove 22. After reaching the target position, it is locked into the corresponding bent locking groove 23. The locking groove 23 limits and fixes the position of the adjusting rod 24, thereby changing the angle between the adjusting rod 16 and the connecting beam 10, and finally adjusting the turning angle and depth of the plow head 18.

[0034] Example 3, based on Example 2, please refer to... Figure 3 The top end of the first adjusting rod 16 is telescopically connected to the third adjusting rod 25, and the first adjusting rod 16 is rotatably connected to the third adjusting rod 25. The bottom of the connecting beam 10 is provided with a rotating groove 27, and the round rod 26 is fixedly installed in the rotating groove 27. The telescopic connection between adjusting rod 3 25 and adjusting rod 1 16 provides the telescopic range of the adjusting rod, facilitating the movement of adjusting rod 24 within sliding groove 22 and engaging groove 23; The adjustable rod 25 and the round rod 26 are movably connected, which facilitates the angular change of the adjustable rod 16 and the mounting cylinder 19.

[0035] The adjusting rod 16 is telescopically connected to the adjusting rod 3 25. When the adjusting rod 24 is moved by the adjusting mechanism, the adjusting rod 3 25 can extend and retract synchronously with the angle change of the adjusting rod 16, providing sufficient extension and retraction for the movement of the adjusting rod 24 in the slide groove 22 and the locking groove 23, thus avoiding component jamming.

[0036] The connecting beam 10 has a rotating groove 27 at the bottom and a built-in fixed round rod 26. The adjusting rod 25 is movably connected to the round rod 26, so that the adjusting rod 16 and the mounting cylinder 19 can rotate around the round rod 26, further optimizing the angle change flexibility of the plow head 18.

[0037] Example 4, based on Example 3, please refer to... Figures 1-2 The mounting cylinder 19 has several slots 21. A mounting ring 20 is movably mounted on the slots 21 and the mounting cylinder 19. The inner ring of the mounting ring 20 has a telescopic groove 28. A locking block 29 is mounted on the telescopic groove 28 by a spring. A toggle plate 30 is fixedly mounted on the locking block 29. By pressing the toggle plate 30, the locking block 29 moves within the telescopic groove 28, thereby engaging or disengaging the locking block 29 from the slot 21. The engagement between the locking block 29 and the locking groove 21 allows the mounting ring 20 to be positioned and installed on the mounting cylinder 19, thus determining the positions of the plowshare 17 and the plow head 18, and setting the spacing for all the plow heads 18.

[0038] Pressing the actuating plate 30 causes the locking block 29 to retract into the telescopic groove 28 by compressing the spring, releasing the engagement between the locking block 29 and the groove 21. This pushes the mounting ring 20 to move along the mounting cylinder 19 to the target position. Releasing the actuating plate 30 allows the spring to return, causing the locking block 29 to engage with the corresponding groove 21, thus fixing the position of the mounting ring 20. Because the plow rod 17 is connected to the mounting ring 20, the spacing of the plow head 18 can ultimately be adjusted. Example 5, based on Example 4, please refer to... Figure 1-2 , Figures 4-5 The top end of the plow rod 17 is fixedly installed with a connecting rod 31, the top end of the mounting ring 20 is provided with a connecting groove 32, the connecting rod 31 is placed in the connecting groove 32, and a spring 33 is fixedly installed in the connecting groove 32, and the spring 33 is fixedly connected to the connecting groove 32. The spring 33 and the connecting groove 32 position the plow rod 17 on the mounting ring 20 and provide the amount of movement for the plow rod 17 to move on the slot 21.

[0039] The curved plow rod 17 is connected by a connecting rod 31 at the top, which is inserted into the connecting groove 32 at the top of the mounting ring 20. The connecting groove 32 is fixed by a spring 33. The connecting rod 31 is fixed by the elastic clamping force of the spring 33, so that the curved plow rod 17 is stably positioned on the mounting ring 20.

[0040] When the plowshare 18 encounters obstacles such as rocks or hard soil, the curved plow rod 17 is driven by the impact force to compress or stretch the connecting rod 31, which in turn moves within a small range in the connecting groove 32, providing a buffer for the movement of the curved plow rod 17 and preventing it from bending or breaking.

[0041] Example 6, based on Example 5, please refer to... Figures 1-2 and Figure 5 The adjusting block 15 has a movable slot 35. One side of the adjusting mechanism 2 36 is engaged in the movable slot 35, and the other side of the adjusting mechanism 2 36 is installed on the plow rod 17. The adjusting mechanism 2 36 provides movement for the plow rod 17 and the adjusting block 15.

[0042] The adjusting block 15 has a movable slot 35 on its upper part. The adjusting mechanism 36 is engaged in the movable slot 35 at one end and connected to the plow rod 17 at the other end, forming a linkage relationship between the plow rod 17 and the adjusting block 15.

[0043] When the plow 18 is turning the soil, the reaction force of the soil on the plow 18 is transmitted to the curved plow rod 17. The curved plow rod 17 drives the adjustment mechanism 2 36 to move adaptively within the movable slot 35, providing additional movement variables for the curved plow rod 17 and ensuring that the plow 18 is always in contact with the surface of the cultivated land.

[0044] Example 7, based on Example 6, please refer to... Figures 5-6 The second adjustment mechanism 36 is a parallelogram composed of two fourth adjustment rods 37 and two fifth adjustment rods 38. The fifth adjustment rod 38 is a telescopic rod that can extend and retract. The fourth adjustment rod 37 near the adjustment block 15 is engaged in the movable slot 35, and the fourth adjustment rod 37 near the curved plow rod 17 is connected to the curved plow rod 17. A pull rod 41 is also fixedly installed on the adjustment rod 37 near the adjustment block 15. Pulling the pull rod 41 separates the adjustment rod 37 from the movable slot 35.

[0045] When the plow rod 17 moves under the reaction force of the soil, the parallelogram frame changes shape by the extension and retraction of the adjusting rod 38 to adapt to the relative position of the plow rod 17 and the adjusting block 15. When it is necessary to disassemble or adjust the adjusting mechanism 36, pull the pull rod 41 on the adjusting rod 37 near the adjusting block 15 to disengage the adjusting rod 37 from the movable slot 35, so as to achieve quick disassembly.

[0046] Example 8, based on Example 7, please refer to... Figure 6The adjusting rod 37 and the adjusting rod 38 are connected by a rotating shaft 39 and a connecting ring 40. The rotating shaft 39 is rotatably connected to the connecting ring 40. The rotating shaft 39 is connected to the adjusting rod 37 and the adjusting rod 38 respectively, so that the adjusting rod 37 and the adjusting rod 38 are rotatably connected, thereby allowing the parallelogram to change shape.

[0047] When the adjustment mechanism 2 36 needs to change shape, the adjustment rod 4 37 and the adjustment rod 5 38 can rotate relative to each other around the pivot 39, causing the parallelogram frame to deform flexibly, ensuring that the adjustment rod 5 38 can extend or retract without rigid obstruction.

[0048] Example 9, based on Example 8, please refer to... Figure 6 An adjustment assembly 42 is installed on the adjustment rod 37. The adjustment assembly 42 includes a first mounting block 43, a second spring 44, and a second mounting block 45. The first mounting block 43 is fixedly connected to the plow rod 17. The second spring 44 is fixedly connected to the first mounting block 43 and the second mounting block 45. The second mounting block 45 is fixedly connected to the adjustment rod 37.

[0049] When the plowshare 18 encounters a large obstacle, the impact force transmitted by the plowshare 17 is first initially buffered by the spring 33, and the remaining impact force is transmitted to the spring 44 through the mounting block 43. The spring 44 further absorbs the impact force by compression or stretching, forming a "double buffer".

[0050] Example 10, based on Example 1, please refer to... Figure 7 A conveying pipe 46 is fixedly installed on one side of the upper end of the mounting cylinder 19. The composite lime-based material is conveyed into the mounting cylinder 19 through the conveying pipe 46. A stirring component 47 is installed inside the mounting cylinder 19. The lime-based material is stirred and mixed by the stirring component 17 in the mounting cylinder 19 and pushed to move. A discharge port 48 is opened at the bottom of the mounting cylinder 19. The lime-based material is discharged through the discharge port 48 and the acidity of the cultivated land is improved. By turning the cultivated land and applying the lime-based material, the acidity improvement of the cultivated land is better achieved.
