Description

Technical Field

[0001] This invention relates to the field of fertilization equipment technology, specifically to a fertilization device for alfalfa cultivation with adjustable functions. Background Technology

[0002] Alfalfa is a perennial herbaceous plant belonging to the genus Alfalfa in the legume family. It is high in protein, with high crude protein content in its hay, a reasonable amino acid composition, and rich in various vitamins and minerals. It is a high-quality feed for livestock such as cattle, sheep, pigs, and rabbits. It can be used for green fodder, haymaking, silage, or processed into hay powder and hay pellets. Therefore, alfalfa planting, processing, and sales have formed an industrial chain. There is a large market demand for hay, hay seeds, and other products. The fertilization equipment for alfalfa planting needs to be selected according to the planting scale, fertilization method, and fertilizer type. The most common fertilization equipment is a fertilizer spreader, which evenly spreads fertilizer onto the ground surface through a conveying device at the bottom of the hopper.

[0003] When adjusting the amount of fertilizer being spread, a baffle is usually used to control the size of the fertilizer spreading gap. However, when the spreading gap is too small, the fertilizer inside directly impacts the baffle, causing the baffle to deform under long-term impact, creating gaps at the spreading position, and causing fertilizer to get stuck during spreading. Summary of the Invention

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A fertilization device for alfalfa cultivation with adjustable functions, comprising:

[0006] A material bin, wherein a guide cylinder is fixedly installed at the center of the bottom of the material bin, a fixing plate is fixedly installed between the guide cylinder and the material bin, a connecting plate is fixedly installed on the outside of the fixing plate, and a base is fixedly installed at the bottom of the guide cylinder;

[0007] A material transfer mechanism is rotatably mounted on the top of the chassis and is located inside the guide cylinder;

[0008] A crushing mechanism is installed on the top of the inner wall of the guide cylinder and is located on top of the material conveying mechanism;

[0009] A shaft groove cylinder is fixedly installed at the bottom of the chassis. A drive shaft is rotatably installed on the inner wall of the shaft groove cylinder. A pulley is fixedly installed at one end of the drive shaft. An arc groove is formed on the bottom of the outer side of the guide cylinder away from the fixed plate. An arc baffle is slidably installed at the arc groove of the guide cylinder. By rotating the stud, the position of the arc baffle is changed, controlling the opening range of the arc groove of the guide cylinder, thereby controlling the fertilizer discharge gap and adjusting the amount of fertilizer sprinkled at one time. Simultaneously, during fertilizer sprinkling, it works in conjunction with the inner turntable. Utilizing the conical surface at the bottom of the inner turntable that slopes downwards from the inside to the outside, it restricts the fertilizer at the edge positions before it is sprinkled out, bearing the pressure of the inner fertilizer pushing the outer material outwards. This prevents the pressure from being directly transmitted to the arc baffle during rotation, which could cause gaps at the connection point and lead to material jamming during fertilizer sprinkling. The guide cylinder has a sliding column fixedly installed on its outer side. The sliding column is symmetrically installed along the center of the guide cylinder's axis. The outer side of the sliding column is slidably adapted to the inner wall of the arc baffle. A stud is rotatably installed on the outer side of the guide cylinder. The outer side of the stud is threadedly connected to the inner wall of the arc baffle. A rotating cylinder is rotatably installed on the inner wall of the guide cylinder. Through the rotational connection between the rotating cylinder and the guide cylinder, when the fertilizer is driven by the material conveying mechanism, if the bottom layer of fertilizer is not thrown out and the upper layer of fertilizer cannot move downward, the friction between the fertilizer and the inner wall of the rotating cylinder causes the rotating cylinder to rotate with the fertilizer. This prevents the fertilizer from being ground and crushed under the friction of the transmission, resulting in a large amount of powder and affecting the throwing effect. The inner diameter of the rotating cylinder gradually increases from top to bottom. An inner rotating disk is rotatably installed on the inner wall of the guide cylinder. The inner rotating disk is located at the bottom of the rotating cylinder, and the bottom of the inner rotating disk is a conical surface that slopes downward from the inside to the outside.

[0010] Preferably, the material transfer mechanism includes a rotating shaft, the outer side of which is rotatably adapted to the inner wall of the chassis, and the bottom end of the rotating shaft penetrates the chassis and extends to its bottom. A gear is fixedly installed at the bottom end of the rotating shaft, and the outer side of the gear meshes with the end of the transmission shaft away from the pulley. A turntable is fixedly installed at the top end of the rotating shaft, and a top plate is fixedly installed at the center of the top of the turntable. A pusher plate is fixedly installed on the outer side of the top plate. The end of the pusher plate away from the top plate is curved. The curved shape of the pusher plate away from the top plate reduces the driving force on the fertilizer at the edge, so that the fertilizer at the edge is pushed out by the movement of the fertilizer on the inner side. This avoids putting too much pressure on the fertilizer that cannot be thrown out in time at the throwing position, which would cause the fertilizer that cannot be thrown out in time at the edge to be ground into powder, affecting the fertilizer throwing and diffusion effect. The pusher plate is evenly installed along the center of the top plate, and the bottom of the pusher plate is tightly attached to the top of the turntable.

[0011] Preferably, an annular groove is formed at the edge of the top of the turntable, and a pad ring is rotatably installed at the annular groove of the turntable. The top slope of the pad ring is inclined upward from the inside to the outside. Through the inclined surface of the top of the pad ring, when the fertilizer at the edge is thrown, the inclined surface guides the fertilizer, so that the fertilizer at the bottom layer is guided by the inclined surface of the pad ring when it is thrown, so that the fertilizer at the bottom layer tends to move obliquely upward when it is thrown, avoiding the fertilizer at the bottom layer falling directly downward when thrown, which would reduce the throwing range and affect the fertilizer throwing effect. The pad ring is located directly below the inner turntable. A rotating column is fixedly installed at the center of the top of the top plate. An auger blade is fixedly installed on the outside of the rotating column. The width of the auger blade gradually increases from top to bottom, and the auger blade is located inside the rotating cylinder. The distance between the auger blade and the rotating cylinder gradually decreases from top to bottom.

[0012] Preferably, the crushing mechanism includes a connecting cylinder, the outer side of which is fixedly connected to the top of the inner wall of the guide cylinder, and the inner diameter of the connecting cylinder gradually decreases from top to bottom. A slotted plate is fixedly installed at the bottom of the inner wall of the connecting cylinder, and an arc-shaped slot is evenly formed at the top of the slotted plate. A connecting plate is rotatably installed on the inner wall of the slotted plate. The bottom of the connecting plate is fixedly connected to the top of the material conveying mechanism, and a rotating slotted plate is fixedly installed at the top of the connecting plate. A guide plate is fixedly installed at the top of the rotating slotted plate, and the outer diameter of the guide plate gradually increases from top to bottom. The outer side of the rotating tray is evenly provided with rotating grooves, and rotating arms are rotatably installed at each of the rotating grooves. A hammer is rotatably installed at one end of each rotating arm, and an elastic washer is fixedly installed between the end of the rotating arm away from the hammer and the rotating tray. By utilizing the elasticity of the elastic washer and its cooperation with the hammer, the centrifugal force generated during rotation causes the hammer to drive the rotating arm to compress the elastic washer ring, bringing the hammer closer to the connecting cylinder and squeezing the fertilizer passing through. This crushes any clumps of fertilizer, preventing them from clogging the arc grooves when being ejected, thus ensuring that subsequent fertilizer can be ejected smoothly.

[0013] Preferably, a pad is fixedly installed on the top of the guide tray, a connecting block is fixedly installed on the top of the pad, a material-pushing plate is fixedly installed on the outside of the connecting block, the material-pushing plate is evenly installed along the center position of the connecting block, a lever is evenly provided on the top of the material-pushing plate, and the lever of the material-pushing plate is located inside the material box.

[0014] This invention provides a fertilization device for alfalfa cultivation with adjustable functions. It has the following features:

[0015] Beneficial effects:

[0016] I. This fertilization equipment for alfalfa planting with adjustable function changes the position of the arc baffle by rotating the stud, controls the opening range of the arc groove of the guide cylinder, and thus controls the fertilizer discharge gap, thereby adjusting the amount of fertilizer sprinkled at one time. Simultaneously, during fertilizer sprinkling, it works in conjunction with the inner turntable. The conical surface at the bottom of the inner turntable, sloping downwards from the inside out, restricts the fertilizer at the edge positions before it is sprinkled out, bearing the pressure of the inner fertilizer pushing the outer material outwards. This prevents the pressure from being directly transmitted to the arc baffle during rotation, which could cause gaps at the connection point and lead to fertilizer jamming during sprinkling.

[0017] Second, this fertilization equipment for alfalfa planting with adjustable function, through the rotational connection between the rotating drum and the guide drum, when the fertilizer is driven by the material transmission mechanism, if the fertilizer at the bottom layer is not thrown out and the fertilizer at the top layer cannot move downwards, the friction between the fertilizer and the inner wall of the rotating drum causes the rotating drum to rotate with the fertilizer, thus preventing the fertilizer from being ground and crushed under the friction of the transmission, resulting in a large amount of powder and affecting the throwing effect.

[0018] Third, the fertilizer application equipment for alfalfa planting with adjustable function reduces the impact on the fertilizer at the edge by using the arc-shaped bend of the pusher plate away from the top plate. This allows the fertilizer at the edge to be pushed out by the movement of the fertilizer on the inside, avoiding excessive pressure on the fertilizer that cannot be thrown out in time at the throwing position, which would cause the fertilizer that cannot be thrown out in time at the edge to be ground into powder, thus affecting the fertilizer throwing and diffusion effect.

[0019] Fourth, this fertilization equipment for alfalfa planting with adjustable function uses the inclined surface at the top of the pad ring to guide the fertilizer at the edge when it is thrown out. This guides the fertilizer at the bottom of the pad ring to move upwards at an angle, preventing it from falling directly downwards and reducing the spreading range, thus affecting the fertilizer spreading effect.

[0020] 5. This fertilization equipment for alfalfa planting with adjustable function uses the elasticity of the elastic pad ring in conjunction with the hammer block. During rotation, the centrifugal force generated by the rotation causes the hammer block to drive the rotating arm to compress the elastic pad ring, bringing the hammer block closer to the connecting cylinder and squeezing the fertilizer passing through. This crushes any clumps of fertilizer and prevents them from clogging the arc groove when being thrown out, thus preventing subsequent fertilizer from being thrown out smoothly.

[0031] 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.

[0032] First embodiment, such as Figures 1 to 4 As shown, the present invention provides a technical solution:

[0033] A fertilization device for alfalfa cultivation with adjustable functions, comprising:

[0034] Material box 1, a guide cylinder 4 is fixedly installed at the center of the bottom of material box 1, a fixing plate 5 is fixedly installed between the guide cylinder 4 and material box 1, a connecting plate 8 is fixedly installed on the outside of the fixing plate 5, and a base plate 9 is fixedly installed at the bottom of the guide cylinder 4.

[0035] Material transfer mechanism 2 is rotatably mounted on the top of chassis 9 and is located inside guide cylinder 4;

[0036] Crushing mechanism 3 is installed on the top of the inner wall of guide cylinder 4 and is located on top of material conveying mechanism 2;

[0037] A shaft groove cylinder 7 is fixedly installed at the bottom of the chassis 9. A drive shaft 12 is rotatably installed on the inner wall of the shaft groove cylinder 7. A pulley 6 is fixedly installed at one end of the drive shaft 12. An arc groove is opened on the bottom of the outer side of the guide cylinder 4 away from the fixed plate 5. An arc baffle 10 is slidably installed at the arc groove of the guide cylinder 4. A sliding column 13 is fixedly installed on the outer side of the guide cylinder 4. The sliding column 13 is symmetrically installed at the center position of the axis of the guide cylinder 4. The outer side of the sliding column 13 is slidably adapted to the inner wall of the arc baffle 10. Before fertilization, the screw 14 can be rotated. The threaded connection between the screw 14 and the arc baffle 10 drives the arc baffle 10 to move up and down at the arc groove of the guide cylinder 4, thereby controlling the opening area of ​​the arc groove of the guide cylinder 4 and controlling the gap area of ​​fertilizer discharge, so as to control the amount of fertilizer applied at one time. The screw 14 is rotatably installed on the outer side of the guide cylinder 4. The outer side of the screw 14 is slidably adapted to the inner wall of the arc baffle 10. The inner wall of the guide cylinder 4 is connected by a threaded connection. The inner wall of the guide cylinder 4 is rotatably mounted with a rotating cylinder 11. The inner diameter of the rotating cylinder 11 gradually increases from top to bottom. The inner wall of the guide cylinder 4 is rotatably mounted with an inner rotating disk 15. During the process of spreading fertilizer, the inner rotating disk 15 cooperates with the material transfer mechanism 2. During the process of pushing the fertilizer outward from the inside, the fertilizer near the bottom of the inner rotating disk 15 is sloping downward from the inside to the outside. This allows the fertilizer to move obliquely downward at the edge and close to the arc groove of the guide cylinder 4 during the process of moving from the inside to the outside. At the same time, during the process of conveying fertilizer, the rotating cylinder 11 is rotatably connected with the inner wall of the guide cylinder 4. When jamming occurs, the rotating cylinder 11 and the material transfer mechanism 2 rotate synchronously to reduce the rotational resistance when jamming. The inner rotating disk 15 is located at the bottom of the rotating cylinder 11, and the bottom of the inner rotating disk 15 is a conical surface that slopes downward from the inside to the outside.

[0038] The second embodiment is based on the first embodiment; please refer to [link / reference]. Figures 5 to 6As shown, the material transfer mechanism 2 includes a rotating shaft 21. The outer side of the rotating shaft 21 is rotatably adapted to the inner wall of the chassis 9, and the bottom end of the rotating shaft 21 penetrates the chassis 9 and extends to its bottom. It is connected to the drive shaft 12 through a gear 28. When the drive shaft 12 is driven to rotate by the tractor, the gear 28 drives the rotating shaft 21 to rotate inside the chassis 9, causing the rotating shaft 21 to drive the turntable 22 to rotate on the top of the chassis 9. The gear 28 is fixedly installed at the bottom end of the rotating shaft 21, and the outer side of the gear 28 is connected to the end of the drive shaft 12 away from the pulley 6. The turntable 2 is fixedly installed at the top end of the rotating shaft 21. 2. A top plate 23 is fixedly installed at the center of the top of the turntable 22. A pusher plate 27 is fixedly installed on the outer side of the top plate 23. The end of the pusher plate 27 away from the top plate 23 is curved. During the rotation, the top plate 23 drives the rotating column 26 to rotate, which in turn drives the crushing mechanism 3 to move. At the same time, the rotating column 26 drives the auger blade 25 to rotate on the inner wall of the rotating drum 11, and drives the fertilizer to move downward to the top of the turntable 22. After the fertilizer reaches the top of the turntable 22, the pusher plate 27 is evenly installed along the center position of the top plate 23, and the bottom of the pusher plate 27 is tightly attached to the top of the turntable 22.

[0039] A ring groove is provided at the top edge of the turntable 22, and a pad ring 24 is rotatably installed at the ring groove of the turntable 22. The top slope of the pad ring 24 is inclined upward from the inside to the outside. The pad ring 24 is located directly below the inner turntable 15. A rotating column 26 is fixedly installed at the center of the top of the top plate 23. An auger blade 25 is fixedly installed on the outside of the rotating column 26. The width of the auger blade 25 gradually increases from top to bottom. During the rotation, the fertilizer is driven by the pusher plate 27. With the centrifugal force of the fertilizer itself during the rotation, the fertilizer at the center position moves outward and close to the arc groove of the guide cylinder 4. At the same time, during the transmission process, the inclined surface of the top of the pad ring 24 is used to guide the fertilizer moving outward. When the fertilizer at the bottom is discharged, it is guided upward by the pad ring 24 and thrown out of the arc groove. The auger blade 25 is located inside the rotating cylinder 11, and the distance between the auger blade 25 and the rotating cylinder 11 gradually decreases from top to bottom.

[0040] The third embodiment is based on embodiments one and two; please refer to [link / reference]. Figures 7 to 9As shown, the crushing mechanism 3 includes a connecting cylinder 301. The outer side of the connecting cylinder 301 is fixedly connected to the top of the inner wall of the guide cylinder 4, and the inner diameter of the connecting cylinder 301 gradually decreases from top to bottom. A slotted plate 305 is fixedly installed at the bottom of the inner wall of the connecting cylinder 301. Arc-shaped slots are evenly opened at the top of the slotted plate 305. A connecting plate 306 is rotatably installed on the inner wall of the slotted plate 305. The bottom of the connecting plate 306 is fixedly connected to the top of the material transfer mechanism 2, and a rotating slotted plate 308 is fixedly installed at the top of the connecting plate 306. The fixed connection between the bottom of 306 and the top of the rotating column 26 causes the connecting plate 306 to rotate on the inner wall of the slotted plate 305 when the rotating column 26 rotates. This causes the rotating plate 308, the guide plate 307, the pad plate 302, and the connecting block 304 to rotate synchronously. The connecting block 304 then drives the material-pushing plate 303 to rotate. Utilizing the characteristic that the lever at the top of the material-pushing plate 303 is located inside the material box 1, the material-pushing plate 303 drives the fertilizer stored in the material box 1 through the lever, causing the fertilizer to fall under its own weight. The top of the rotating plate 308 is fixedly installed. A guide plate 307 is provided, with its outer diameter gradually increasing from top to bottom. A rotating groove is evenly distributed on the outer side of a rotating disk 308, and a rotating arm 310 is rotatably mounted at each groove. A hammer 309 is rotatably mounted at one end of each rotating arm 310. When fertilizer falls inside the connecting cylinder 301, the guide plate 307 guides the falling fertilizer, causing it to enter the gap between the connecting cylinder 301 and the rotating disk 308. As the rotating disk 308 rotates, it drives the rotating arm 310 and the hammer 309 to rotate as well. The centrifugal force of the rotating hammer 309 drives the rotating arm 310 to rotate on the inner wall of the rotating trough 308. The end of the rotating arm 310 away from the hammer 309 compresses the elastic washer ring 311 and deforms, so that the hammer 309 is close to the connecting cylinder 301 and squeezes the fertilizer passing through. When the fertilizer clumps, the clumps are squeezed to break them up, so that the fertilizer can fall smoothly through the arc groove of the through trough 305. The elastic washer ring 311 is fixedly installed between the end of the rotating arm 310 away from the hammer 309 and the rotating trough 308.

[0041] A pad 302 is fixedly installed on the top of the guide plate 307, a connecting block 304 is fixedly installed on the top of the pad 302, a material-pushing plate 303 is fixedly installed on the outside of the connecting block 304, the material-pushing plate 303 is evenly installed along the center position of the connecting block 304, and a lever is evenly provided on the top of the material-pushing plate 303, and the lever of the material-pushing plate 303 is located inside the material box 1.

[0042] In use, the equipment is fixed to the tractor via the connecting plate 8, and the tractor is connected to the pulley 6 via a belt. Fertilizer is added to the hopper 1. During use, the tractor drives the equipment to move in the planting field, and the pulley 6 drives the drive shaft 12 to rotate, which in turn drives the material conveying mechanism 2 and the crushing mechanism 3 to move. This causes the fertilizer in the hopper 1 to move downward along the guide cylinder 4, enter the top of the chassis 9, and be discharged from the arc groove of the guide cylinder 4 under the drive of the material conveying mechanism 2, spreading it outward to complete the fertilization of the planting land.

[0043] Before fertilization, the screw 14 can be rotated, and the threaded connection between the screw 14 and the arc baffle 10 can be used to drive the arc baffle 10 to move up and down at the arc groove of the guide cylinder 4. This controls the opening area of ​​the arc groove of the guide cylinder 4 and controls the gap area of ​​fertilizer discharge, thereby controlling the amount of fertilizer to be scattered at one time. At the same time, during the fertilizer scattering process, the inner turntable 15 cooperates with the material conveying mechanism 2. As the fertilizer is pushed outward from the inside, the slope of the bottom of the inner turntable 15 from the inside to the outside causes the fertilizer near the bottom of the inner turntable 15 to move obliquely downward at the edge and close to the arc groove of the guide cylinder 4 during the outward movement. At the same time, during the fertilizer conveying process, the rotating connection between the rotating cylinder 11 and the inner wall of the guide cylinder 4 causes the rotating cylinder 11 and the material conveying mechanism 2 to rotate synchronously when jamming occurs, reducing the rotational resistance when jamming occurs.

[0044] In the material transfer mechanism 2, the gear 28 meshes with the drive shaft 12, so that when the drive shaft 12 is driven to rotate by the tractor, the gear 28 drives the rotating shaft 21 to rotate inside the chassis 9, so that the rotating shaft 21 drives the turntable 22 to rotate on the top of the chassis 9. During the rotation, the top plate 23 drives the rotating column 26 to rotate, so that the rotating column 26 drives the crushing mechanism 3 to move, and at the same time drives the auger blade 25 to rotate on the inner wall of the rotating drum 11, and drives the fertilizer to move downward to the top of the turntable 22. After the fertilizer reaches the top of the turntable 22, during the rotation, the pusher plate 27 drives the fertilizer, and with the centrifugal force of the fertilizer itself during the rotation, the fertilizer in the center position moves outward and close to the arc groove of the guide cylinder 4. At the same time, during the transmission process, the inclined surface of the top of the pad ring 24 is used to guide the fertilizer moving outward, so that the fertilizer at the bottom layer is guided upward by the pad ring 24 and thrown out of the arc groove when it is discharged.

[0045] In the crushing mechanism 3, the bottom of the connecting plate 306 is fixedly connected to the top of the rotating column 26. When the rotating column 26 rotates, it drives the connecting plate 306 to rotate on the inner wall of the slotted plate 305. This causes the rotating plate 308, the guide plate 307, the pad plate 302, and the connecting block 304 to rotate synchronously. The connecting block 304 then drives the material-pushing plate 303 to rotate. Utilizing the characteristic that the lever at the top of the material-pushing plate 303 is located inside the material box 1, the material-pushing plate 303 drives the fertilizer stored in the material box 1 through the lever. The fertilizer falls under its own weight. When the fertilizer falls inside the connecting cylinder 301, it is guided by the guide plate 307. The falling fertilizer is guided to enter the gap between the connecting cylinder 301 and the rotating tray 308. When the rotating tray 308 rotates, it drives the rotating arm 310 and the hammer block 309 to rotate. The centrifugal force of the rotating hammer block 309 drives the rotating arm 310 to rotate on the inner wall of the rotating tray 308. The end of the rotating arm 310 away from the hammer block 309 compresses the elastic pad ring 311 and deforms, so that the hammer block 309 moves closer to the connecting cylinder 301 and squeezes the fertilizer passing through. When the fertilizer clumps together, it is squeezed to break the clumps and allow the fertilizer to fall smoothly through the arc groove of the through tray 305.
