Description

Technical Field

[0001] The utility model relates to the technical field of sowing or fertilizing, in particular to a biochar-based fertilizer soil repair device. Background Art

[0002] Biochar is a highly aromatic carbon-rich substance obtained by high-temperature pyrolysis of crop straw, woody materials, livestock manure or other organic materials in a low-oxygen environment. Biochar-based fertilizer can reduce the number of fertilization times. After application to the soil, it can significantly increase soil nutrients and has a good effect on soil repair. When using biochar-based fertilizer to repair the soil, some repair devices will be used.

[0003] The repair device generally sends the agglomerated biochar-based fertilizer into it for crushing, and then spreads the crushed fertilizer into the soil. Because the amount of fertilizer required for the soil in different places is different, the amount of fertilizer applied by the repair device will be controlled. The current fertilizer amount control device is installed at the discharge port, so that the amount of fertilizer applied can be changed according to needs. However, after the amount of fertilizer is reduced, the amount of fertilizer entering the device for crushing remains unchanged, which will cause excessive accumulation of fertilizer inside the device, which will bring a burden to the crushing components inside the device, and thus reduce the service life of the soil repair device. Utility Model Content

[0005] In response to the shortcomings of the existing technology, the utility model provides a biochar-based fertilizer soil remediation device, which has the function of preventing excessive fertilizer from accumulating inside the device while adjusting the fertilizer application amount of the device. As a result, after the fertilizer application amount is reduced, fertilizer will not accumulate inside the device, thereby avoiding the burden on components caused by fertilizer accumulation and improving the service life of the device.

[0006] (2) Technical solution

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a biochar-based fertilizer soil remediation device, comprising a main body block, a push rod fixedly connected to the rear side of the main body block, and a transmission rod provided on the lower side of the main body block;

[0008] Among them, the upper side of the main body block is fixedly connected to a feed pipe communicating with the interior, and the upper side of the feed pipe is fixedly connected to a feed funnel;

[0009] Among them, the main body block is rotatably connected to the crushing roller, and the lower side of the main body block is integrally formed with a discharge port connected to the interior. A flow limiting mechanism is set inside the feed pipe, which can change the amount of feed into the feed pipe, thereby achieving the purpose of changing the amount of fertilizer applied;

[0011] Preferably, both left and right ends of the transmission rod are rotatably connected to moving wheels, and a fixed block is fixedly sleeved on the outer surface of the transmission rod, and the fixed block is fixedly connected to the lower side of the main body block.

[0012] Preferably, the fixed flow limiting block is arranged inside the feed pipe, and a fixed ring is fixedly sleeved on the outer surface of the fixed flow limiting block;

[0013] The fixing ring is fixedly connected to the inner surface of the feed pipe, and a sliding groove is provided inside the fixing ring.

[0014] Preferably, the rotating flow limiting block is movably connected to the interior of the sliding groove, and the outer surface of the feed pipe is provided with a first rotating groove communicating with the interior;

[0015] Wherein, the outer surface of the fixed current limiting block is provided with a second rotating groove which is connected with the sliding groove.

[0016] Preferably, a plurality of limiting blocks are fixedly connected to the bottom wall of the first rotating groove, and the control rod is fixedly connected to the outer surface of the rotating current limiting block;

[0020] (3) Beneficial effects

[0021] Compared with the existing technology, the present invention provides a biochar-based fertilizer soil remediation device with the following beneficial effects:

[0022] (1) The biochar-based fertilizer soil remediation device rotates the control lever, which drives the rotating flow limiting block to rotate, and then the rotating flow limiting block moves out of the inside of the sliding groove. The moved sliding groove will make the feed port of the feed pipe smaller, thereby completing the flow limiting of the feed. The carbon-based fertilizer entering the inside of the main block will be crushed by the crushing roller and finally fall onto the soil through the discharge port. Rotating the control lever in the opposite direction can increase the feed port, thereby increasing the amount of fertilizer applied. In this way, the feed amount will be directly limited during feeding, thereby avoiding excessive fertilizer accumulation inside the device. After the fertilizer amount is reduced, fertilizer will not accumulate inside the device, thereby avoiding the burden of fertilizer accumulation on components, thereby increasing the service life of the device.

[0023] (2) In the biochar-based fertilizer soil remediation device, when the control lever is turned, the worker needs to move the engaging block upward, thereby releasing the engaging state between the engaging block and the limit block, and then the control lever can be turned. After the rotation is completed and the control lever is released, the spring begins to reset from the compressed state, pushing the engaging block to reset. After the reset, the engaging block will form an engaging limit with the limit block. In this way, it can be avoided that the rotating current limiting block will be pushed by the fertilizer during the working process, thereby causing the fertilization amount to change.

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] See also Figures 1 to 5The utility model provides a new technical solution: a biochar-based fertilizer soil remediation device, including a main body block 1, a push rod 2 is fixedly connected to the rear side of the main body block 1, a transmission rod 3 is provided on the lower side of the main body block 1, and the left and right ends of the transmission rod 3 are rotatably connected to the moving wheels 4. The outer surface of the transmission rod 3 is fixedly sleeved with a fixed block 5, and the fixed block 5 is fixedly connected to the lower side of the main body block 1. The upper side of the main body block 1 is fixedly connected to a feeding pipe 6 connected to the interior, and a feeding funnel 7 is fixedly connected to the upper side of the feeding pipe 6. The interior of the main body block 1 is rotatably connected to a crushing roller 8, and the lower side of the main body block 1 is integrally formed with a discharge port 9 connected to the interior. A flow limiting mechanism is provided inside the feeding pipe 6, which can change the feeding amount of the feeding pipe 6, thereby achieving the purpose of changing the amount of fertilizer applied. The flow limiting mechanism includes a fixed flow limiting block 10, a rotating flow limiting block 13 and a control rod 17.

[0032] Furthermore, a fixed flow limiting block 10 is arranged inside the feed pipe 6, and a fixed ring 11 is fixedly sleeved on the outer surface of the fixed flow limiting block 10, and the fixed ring 11 is fixedly connected to the inner surface of the feed pipe 6. A sliding groove 12 is provided inside the fixed ring 11, and a rotating flow limiting block 13 is movably connected to the inside of the sliding groove 12. A first rotating groove 14 communicating with the interior is provided on the outer surface of the feed pipe 6, and a second rotating groove 15 communicating with the sliding groove 12 is provided on the outer surface of the fixed flow limiting block 10. The first rotating groove Several limit blocks 16 are fixedly connected to the bottom wall 14, and a control rod 17 is fixedly connected to the outer surface of the rotating current limiting block 13. The control rod 17 extends out of the feed pipe 6 through the second rotating groove 15 and the first rotating groove 14. A clamping block groove 18 is integrally formed on the lower side of the control rod 17, and a clamping block 19 is slidably connected to the inside of the clamping block groove 18. A spring 20 is fixedly connected to the upper side of the clamping block 19. The upper end of the spring 20 is fixedly connected to the top wall of the clamping block groove 18, and the clamping block 19 is adapted to the limit block 16.

[0033] Furthermore, when the amount of fertilizer needs to be changed, the worker rotates the control lever 17, and the control lever 17 drives the rotating flow-limiting block 13 to rotate, and then the rotating flow-limiting block 13 moves out of the inside of the sliding groove 12. The moved sliding groove 12 will make the feed port of the feed pipe 6 smaller, thereby completing the flow limiting of the feed. The carbon-based fertilizer entering the inside of the main block 1 will be crushed by the crushing roller 8, and finally fall onto the soil through the discharge port 9. Rotating the control lever 17 in the opposite direction can increase the feed port, thereby increasing the amount of fertilizer. When rotating the control lever 17, the worker needs to move the clamping block 19 upward, and then the clamping block 19 will move to the inside of the clamping block groove 18. At this time, the spring 2 0 becomes a compressed state, at this time the engagement state of the clamping block 19 and the limit block 16 is released, and then the control rod 17 can be rotated. After the rotation and release of the control rod 17 are completed, the spring 20 begins to reset from the compressed state, pushing the clamping block 19 to reset. After the reset, the clamping block 19 will move between the limit blocks 16, and then the limit blocks 16 will form a clamping limit for the clamping block 19. In this way, the feed amount will be directly limited during feeding, thereby avoiding excessive fertilizer accumulation inside the device, and then after the fertilization amount is reduced, fertilizer will not accumulate inside the device, thereby avoiding the burden of fertilizer accumulation on components, thereby improving the service life of the device.

[0034] Working principle: When the amount of fertilizer needs to be changed, the worker rotates the control lever 17, and the control lever 17 drives the rotating flow-limiting block 13 to rotate, and then the rotating flow-limiting block 13 moves out of the inside of the sliding groove 12. The moved sliding groove 12 will make the feed port of the feed pipe 6 smaller, thereby completing the flow control of the feed. The carbon-based fertilizer entering the main block 1 will be crushed by the crushing roller 8 and finally fall onto the soil through the discharge port 9. Rotating the control lever 17 in the opposite direction can increase the feed port, thereby increasing the amount of fertilizer applied. When the lever 17 is moved, the worker needs to move the clamping block 19 upward, and then the clamping block 19 will move to the inside of the clamping block groove 18. At this time, the spring 20 becomes compressed, and the clamping state of the clamping block 19 and the limit block 16 is released, and then the control lever 17 can be rotated. After the rotation is completed and the control lever 17 is released, the spring 20 begins to reset from the compressed state, pushing the clamping block 19 to reset. After the reset, the clamping block 19 will move between the limit blocks 16, and then the limit blocks 16 will form a clamping limit for the clamping block 19.
