DETAILED DESCRIPTION

[0027] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0028] As attached Figure 1 To the attached Figure 6 As shown:

[0029] Embodiment: The present invention provides a degraded land reclamation and fertilization device, comprising a placement base plate 1, a horizontal power main shaft 2 disposed below the placement base plate 1, a rotary tiller blade 3 disposed at intervals on the power main shaft 2, and a power assembly cooperating with the power main shaft 2 disposed on the top of the placement base plate 1;

[0030] It also includes a placement base plate 2 4, which can be detachably installed at the tail end of the placement base plate 1, a fertilizer placement tube 5 is provided on the top of the placement base plate 2 4, a feed pipe 6 is provided at the bottom of the fertilizer placement tube 5, and a horizontally movable feed pipe 2 7 is provided near the bottom of the feed pipe 6, and discharge pipes 8 are provided at intervals on the feed pipe 2 7, and an anti-blocking guide component is provided on the top of the placement base plate 2 4 to drive the discharge pipe 8 to rotate.

[0031] It should be noted that, by disassembling and connecting the placement base plate 1 and the placement base plate 2 4, a power main shaft 2 is provided at the bottom of the placement base plate 1, and rotary tillage blades 3 are installed at intervals on the power main shaft 2. The rotary tillage blades 3 can be driven by the power assembly to rotate so as to crush the soil. The fertilizer placement cylinder 5 is installed on the top of the placement base plate 2 4. The fertilizer passes through the feed pipe 1 6 and the feed pipe 2 7 and finally comes out of the discharge pipe 8. Fertilization is carried out after the soil is crushed, realizing an integrated design of reclamation and fertilization, thereby improving work efficiency.

[0032] Moreover, the anti-blocking guide component can be used to rotate the feed pipe 2 7 to adjust the discharge direction of the discharge pipe 8. When the feed pipe 2 7 or the discharge pipe 8 is blocked, it can be rotated to effectively prevent fertilizer blockage. Moreover, by controlling the discharge port angle of the discharge pipe 8, the discharge direction can be adjusted according to the on-site fertilization environment to improve fertilization flexibility.

[0033] In this embodiment, the number of the rotary tiller blades 3 is no less than two and the number of blades of each rotary tiller blade 3 is no less than three, and the blades of the rotary tiller blades 3 are arc-shaped.

[0034] It should be noted that arranging multiple rotary tillage blades 3 distributed side by side and configuring multiple arc-shaped blades on each blade can increase the contact area with the soil and the crushing frequency, thereby improving the uniformity and efficiency of soil crushing.

[0035] Among them, the curved blade design is more in line with the principles of mechanics when rotating, which can effectively cut into the soil and flip it along the way, reducing power loss, while reducing the risk of blade damage caused by impact from hard objects and extending its service life.

[0036] In this embodiment, the power assembly includes an engine 9, a reducer 10, a power wheel 11 and a power belt 12. The external power supply of the engine 9 is installed on the top of the placement base 1, the reducer 10 is installed below the placement base 1, the power main shaft 2 and the output shaft of the reducer 10 are interconnected, the power wheel 11 and the input shaft of the reducer 10 are interconnected, and the power belt 12 is connected to the power wheel 11 and the output shaft of the engine 9.

[0037] It should be noted that the engine 9 is used to provide power, which is transmitted to the input shaft of the reducer 10 and the power wheel 11 through the power belt 12, and then the power main shaft 2 is driven to rotate after being decelerated and torque-increased by the reducer 10. The power transmission is stable, and the belt transmission method has a buffered overload, which is convenient for installation and maintenance. The reducer 10 directly drives the power main shaft 2 to ensure that the rotary blade 3 obtains sufficient torque for efficient soil crushing.

[0038] In this embodiment, a guardrail 13 is provided on the top of the placement base plate 1 and in front of the engine 9, a fixedly connected positioning plate 14 is provided at the tail end of the placement base plate 1, and vertically spaced positioning holes 15 are provided inside the positioning plate 14 and along the length direction. A positioning rod 16 is provided inside the positioning plate 14 and passes through the positioning holes 15. The side of the positioning plate 14 away from the placement base plate 1 is provided with spaced mounting grooves 17, and the vertical cross-sectional profile of the mounting grooves 17 is rectangular.

[0039] It should be noted that the guardrail 13 is provided in front of the engine 9 to effectively prevent the operator from accidentally contacting high-temperature or rotating parts, thereby improving operation safety.

[0040] The positioning plate 14 and the rectangular mounting groove 17 thereon provide precise guidance and positioning reference for the connection of the placement base plate 2 4. The multiple positioning holes 15 vertically spaced along the length direction, combined with the positioning plug rod 16, allow the relative height between the two placement base plates 1 and 2 4 to be adjusted according to actual needs during connection. When the height of the placement base plate 1 is adjusted, the depth of the rotary tiller 3 below can be controlled, thereby ultimately adjusting the fertilization depth, thereby increasing the adaptability of the device.

[0041] In this embodiment, guide blocks 18 are provided at intervals on the side of the placement base plate 2 4 close to the placement base plate 1 1. The guide blocks 18 cooperate with the mounting grooves 17. The same positioning holes 15 are also provided in each guide block 18. Locking nuts 19 are symmetrically provided on the positioning rods. After the positioning rods pass through the positioning holes 15 in the positioning plate 14 and the guide blocks 18, the locking nuts 19 are screwed from both ends of the positioning rods to each other and fit into the positioning plate 14. Lifting handles 20 are provided on the left and right side walls of the placement base plate 1 1.

[0042] It should be noted that the guide block 18 is precisely matched with the rectangular mounting groove 17 on the positioning plate 14 to ensure that the placement base plate 2 4 can be quickly and accurately aligned and inserted into the placement base plate 1 1. When the guide block 18 is inserted into the mounting groove 17 and the block is aligned with the positioning hole 15 on the positioning plate 14, the positioning rod 16 is inserted and then tightened with the locking nuts 19 at both ends. This can rigidly connect the placement base plate 1 1 and the placement base plate 2 4 together, effectively preventing the two from loosening during operation vibration, and ensuring that the placement base plate 1 1 and the placement base plate 2 4 are firmly and reliably connected.

[0043] At the same time, the placement base plate 1 and the placement base plate 2 4 are designed to be disassembled for easy transportation. In addition, if the components on the placement base plate 1 or the placement base plate 2 4 are damaged, the two can be disassembled for easy maintenance. The lifting handle 20 is convenient for manual lifting of the placement base plate 1 to facilitate transportation or docking.

[0044] In this embodiment, a hollow internal limiting ring 21 is provided on the top of the placement base plate 24, the fertilizer placement tube 5 is placed in the limiting ring 21, a detachable cover plate 22 is provided on the top of the fertilizer placement tube 5, and a fixing rope 23 is provided on the top of the limiting ring 21. The fixing rope 23 is fastened to the top of the cover plate 22.

[0045] It should be noted that the limiting ring 21 supports and limits the position of the fertilizer placement cylinder 5 from the bottom to prevent it from shifting sideways or tipping over due to vibration during operation. The detachable cover 22 is convenient for adding fertilizer at any time. The fixing rope 23 is fastened to the top of the cover 22, further constraining the fertilizer placement cylinder 5 in the limiting ring 21, forming a double fixation. Even when working on bumpy terrain, the fertilizer cylinder can be ensured to be stable to prevent accidental falling off or overturning that may cause the fertilizer to spill.

[0046] In this embodiment, the diameter of the feed pipe 2 7 is smaller than the diameter of the feed pipe 1 6, and the diameter of the discharge pipe 8 is smaller than the diameter of the feed pipe 2 7. The anti-blocking guide assembly includes an adjusting gear 24, a linkage rack 25 and a pneumatic part 26. The adjusting gear 24 is symmetrically installed on the feed pipe 2 7 and on both sides of the feed pipe 1 6. The pneumatic part 26 is symmetrically installed on the top of the placement base plate 2 4. The linkage rack 25 is vertically located below the placement base plate 2 4 and the top cooperates with the pneumatic part 26. The gear teeth on the side wall of the linkage rack 25 cooperate with the adjusting gear 24. A clamping plate 27 is symmetrically provided on the linkage rack 25. The inner side wall of the clamping plate 27 is movably fitted with the left and right side walls of the adjusting gear 24.

[0047] It should be noted that the feed pipe 1 6 , feed pipe 2 7 and discharge pipe 8 are designed with gradually decreasing diameters, which helps to form a certain pressure gradient during the fertilizer transportation process, promotes fertilizer flow, and forms a relatively concentrated fertilization point at the discharge port.

[0048] The anti-blocking guide assembly uses symmetrically arranged pneumatic parts 26, such as a cylinder to drive the linkage rack 25 to move up and down, and the rack drives the adjusting gear 24 engaged with it to rotate, thereby accurately controlling the rotation of the conveying pipe 2 7 in the conveying pipe 1 6. At the same time, a limiting ring is symmetrically installed on the outer wall of the conveying pipe. The limiting ring and the conveying pipe 1 6 fit together, so that no displacement will occur during the rotation of the conveying pipe 2 7.

[0049] The symmetrically arranged clamping plates 27 act as a limit when the adjusting gear 24 rotates, ensuring that the rotation is smooth and reliable.

[0050] Specifically, in the initial state, the discharge port of the discharge pipe 8 faces downward, so that the fertilizer can fall. When the fertilizer blocks the discharge pipe 8, the piston rod of the cylinder drives the linkage rack 25 to move downward, and the linkage rack 25 cooperates with the adjusting gear 24 to rotate the adjusting gear 24 to drive the feed pipe 27 to rotate, so that the discharge pipe 8 rotates upward. During the back and forth rotation, the fertilizer in the discharge pipe 8 vibrates and falls. When there is no blockage, the direction of the discharge pipe 8 can be rotated to adjust different discharge angles to adapt to different row spacings or terrains.

[0051] In this embodiment, a fan 28 with an external power supply is provided on the top of the placement base plate 24 and behind the fertilizer placement cylinder 5. An air supply pipe 29 is provided on the air outlet of the fan 28. The outer diameter of the air supply pipe 29 is smaller than the inner diameter of the feed pipe 6. The other end of the air supply pipe 29 passes downward through the placement base plate 24 and enters the feed pipe 6, and the air outlet of the air supply pipe 29 is set downward in the feed pipe 6.

[0052] It should be noted that a fan 28 is provided behind the fertilizer placement cylinder 5, and its air supply pipe 29 extends into the interior of the feed pipe 1 6 and blows air downward. This design forms a downward airflow in the feed pipe, which can continuously provide positive pressure to the feed pipe 2 7 and the discharge pipe 8, helping the fertilizer to overcome the friction resistance of the pipe wall and fall smoothly. This is particularly effective for powdered or hygroscopic fertilizers with poor fluidity.

[0053] On the other hand, the downward-flowing airflow can blow away fertilizer clumps that may accumulate on the pipe wall or at the joints, playing an active anti-blocking role. It is an important supplement to the anti-blocking guide component and further improves the reliability of the fertilization system.

[0054] In this embodiment, a vertical plate 30 is symmetrically provided at the bottom of the placing base plate 2 4 behind the discharge pipe 8, and a covering plate 31 is provided at the bottom of the vertical plate 30. The covering plate 31 is an arc-shaped plate and the distance between the two covering plates 31 gradually increases as it approaches the discharge pipe 8. Guide wheels 32 are symmetrically provided below the placing base plate 1 and in front of the rotary tiller 3. A wheel axle 33 is provided between the two guide wheels 32, and a vertical support plate 34 is provided in the middle of the wheel axle 33. A base plate vertical beam 35 is provided at the bottom of the placing base plate 1, and the support plate 34 is adjustably installed on the base plate vertical beam 35.

[0055] It should be noted that the covering plate 31 arranged behind the discharge pipe 8 has an arc-shaped design and a structure with a small front-end spacing and a large rear-end spacing. It can naturally guide the soil on both sides of the soil after being broken and fertilized by the rotary blade 3 to the middle for covering, thereby achieving immediate covering after fertilization, reducing the loss of fertilizer exposure and volatilization, and improving fertilizer efficiency.

[0056] The guide wheel 32 is located in front of the rotary tiller 3, supporting the front weight of the entire device and controlling the working depth. The adjustment installation between the support plate 34 and the base plate vertical beam 35, such as fixing it with bolts at holes at different heights, allows precise adjustment of the height of the guide wheel 32 relative to the base plate 1, thereby controlling the depth of the rotary tiller 3 into the soil to adapt to land of different hardness or different reclamation requirements.

[0057] In this embodiment, a vertical fixed plate 36 is provided at the bottom and tail end of the placement base plate 2 4, and a driving member 37 with an external power supply is provided on the side wall of the fixed plate 36 near the bottom, and a moving wheel 38 is provided on the other side of the driving member 37 and is interconnected therewith. A hand-held push rod 39 tilted backward is symmetrically provided on the top of the placement base plate 2 4, and a control handle 40 is provided at the end of the hand-held push rod 39. The two control handles 40 are respectively connected to the engine 9 and the driving member 37 through wires.

[0058] It should be noted that a moving wheel 38 driven by a driving member 37 is provided at the tail end of the base plate 2 4. The driving member 37 is driven by an electric motor and combined with a handheld push rod 39, so that the entire device has the ability to walk on its own. The operator can control the start and stop and speed of the engine 9 and the driving member 37 through the control handle 40 on the handheld push rod 39, thereby controlling the tillage speed of the rotary blade 3 and the walking speed of the device. This not only improves the flexibility of the device, but also realizes automated reclamation and fertilization, which is particularly suitable for large-area or long-distance reclamation and fertilization operations.

Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations of the present invention. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present invention.
