Description

Technical Field

[0001] This invention belongs to the field of agricultural fertilization machinery technology, specifically a solid manure application device and method. Background Technology

[0002] Solid manure is rich in nutrients such as nitrogen, phosphorus, and potassium, and is one of the important sources of organic fertilizer in agricultural production. However, traditional methods of manure application suffer from problems such as low efficiency, uneven distribution, and high labor intensity, making it difficult to meet the needs of modern large-scale and precision agriculture.

[0003] In the prior art, such as the invention patent with publication number CN112703870B, the coaxial counter-rotating double-layer disc fertilizer spreader can spread fertilizer with a wide coverage area. However, the single disc component it uses cannot achieve precise fertilization of plants, and its tilt angle cannot be adjusted in a limited way, making it difficult to make fine adjustments according to soil conditions and crop needs. Therefore, it is necessary to provide a solid manure application device and method to solve the problems mentioned in the background art. Summary of the Invention

[0005] The bottom of the manure box has two symmetrical discharge ports, each of which is connected to a conveying pipe. The other end of the conveying pipe is connected to the fertilizer application tray unit.

[0006] Two outer protective plates on the same side are each provided with a frame plate in parallel. Two spring rods are symmetrically connected to the frame plate. One end of each spring rod is connected to the outer protective plate. The material conveying pipe is limited and inserted between the frame plate and the outer protective plate.

[0007] Preferably, the fertilizer applicator unit includes a fertilizer cylinder, which is fixed to the lower end face of the mounting plate. A fixing cover is detachably installed on one side of the fertilizer cylinder, and a feed hole is opened on the upper end face of the fixing cover. A crushing disc is rotatably connected to the center of the fertilizer cylinder, and a grinding plate is fixed to the fertilizer cylinder above the crushing disc by bolts.

[0008] A rotating shaft is vertically fixed in the middle of the crushing disc, and a pipe seat is fixed on the upper end face of the mounting plate directly above the fertilizer cylinder. The rotating shaft is rotatably connected to the pipe seat through a bearing, and a main gear is fixed at the end of the rotating shaft. A driving part is provided inside the pipe seat, and the driving part is connected to the main gear for transmission through gear meshing.

[0009] A cover plate is fixed below the fertilizer cylinder, and a fertilizer spreading plate is coaxially rotatably arranged below the cover plate. The lower end of the rotating shaft is connected to the fertilizer spreading plate. Multiple guide holes are distributed around the lower end face of the fertilizer cylinder.

[0010] Preferably, the fertilizer spreading disc has multiple feeders distributed around its circumference, and each feeder is fitted with a shaft pin, which is rotatably connected to the fertilizer spreading disc.

[0011] One end of the feeder is fixed with a shaft assembly, and a baffle plate is slidably connected to the shaft assembly;

[0012] The fertilizer spreading disc is rotatably connected to an outer shaft ring in the middle, and one end of each of the baffle plates is connected to the outer shaft ring.

[0013] Preferably, the baffle plate is made of high-elasticity stainless steel spring steel.

[0014] Preferably, an inner rod is slidably connected inside the rotating shaft, and a positioning shaft is vertically fixed on the side wall of the inner rod; a ring is rotatably connected to the fertilizer spreading disc, and an outer ring is coaxially fixed outside the ring; an inclined guide groove is provided on the inner wall of the ring, and the positioning shaft is slidably connected to the inclined guide groove.

[0015] Preferably, the tube seat has a guide cavity at its center, and a piston rod is slidably connected to the guide cavity. The upper end of the inner rod is rotatably connected to the piston rod. An air pump is installed above the tube seat and is sealed to the guide cavity.

[0016] Preferably, one end of each mounting plate is fixed with a bevel gear, and a coupling is horizontally rotatably mounted between the outer protective plates. Both ends of the coupling are fixed with bevel gears, which mesh with each of the bevel gears for transmission. A transmission tooth is fixed on the coupling, and the coupling is transmitted to an external power source through the transmission tooth.

[0017] Preferably, the two fertilizer tray units are located on both sides of the seedling, and manure is spread simultaneously to form a cross-coverage; a spiral guide vane is rotatably installed inside the manure box.

[0018] Preferably, a method for applying solid manure includes the following steps:

[0019] S1. Open the cover of the manure box and add the pre-treated solid manure into the manure box. The solid manure enters the fertilizer cylinder in each fertilizer tray unit through the two discharge ports at the bottom of the manure box.

[0020] S2. Based on crop needs and field conditions, the coupling is driven to rotate by an external power source, thereby adjusting the fertilization angle of the fertilizer application disc unit to ensure that the manure can be evenly spread and cover both sides of the seedlings. At the same time, the flow rate of the conveying pipe is adjusted according to the actual situation in order to control the amount of fertilizer applied each time.

[0021] S3. The two fertilizer application units operate simultaneously, and solid manure can preferentially enter between the crushing disc and the grinding plate. The solid manure is initially crushed and refined through the relative rotational motion of the crushing disc and the grinding plate.

[0022] S4. The refined solid manure can be evenly spread on the spreading disc through each feed hole, and the spreading disc spreads the solid manure in the planting area while rotating.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] In this invention, the two fertilizer tray units set below the manure box can adjust the fertilization angle by deflecting the mounting plate, thereby ensuring both the wide coverage of manure spreading and precise fertilization of plants, avoiding insufficient manure application to the plants.

[0025] The fertilizer spreading disc used in this invention can precisely control the amount of fertilizer applied according to different operating conditions under different speed adjustments, thereby improving the flexibility of fertilization. In particular, multiple circumferentially arranged baffles are distributed on the surface of the fertilizer spreading disc. The baffles can bend and deform with the rotation of the outer shaft ring, thereby changing the material guide trajectory. This ensures that while maintaining the amount of fertilizer applied, the range of manure spreading on the fertilizer spreading disc can be effectively adjusted, ensuring that the ideal coverage range can be achieved under different operating conditions.

[0034] Please see Figures 1-7 In this embodiment of the invention, a solid manure application device includes: a manure box 1, a frame 12, an outer protective plate 13, a fertilizer application tray unit 2, and a conveying pipe 15; the frame 12 is fixed to the bottom of the manure box 1, a cover plate 11 is installed on the top of the manure box 1, a plurality of outer protective plates 13 are vertically and symmetrically fixed below the frame 12, and an installation plate 14 is rotatably connected between the outer protective plates 13; two fertilizer application tray units 2 are provided, and each fertilizer application tray unit 2 is correspondingly fixed on the installation plate 14.

[0035] The bottom of the manure box 1 has two symmetrical discharge ports, each of which is connected to a conveying pipe 15. The other end of the conveying pipe 15 is connected to the fertilizer tray unit 2. This allows solid manure to enter the two fertilizer tray units 2 through the conveying pipe 15, and the fertilizer tray units 2 can then spread the solid manure.

[0036] Two outer protective plates 13 located on the same side are each provided with a parallel support plate 16. Two spring rods 17 are symmetrically connected to the support plate 16. One end of the spring rod 17 is connected to the outer protective plate 13. The conveying pipe 15 is limited and inserted between the support plate 16 and the outer protective plate 13, thereby limiting and securing the conveying pipe 15 to prevent it from being tangled by the working environment during fertilizer spreading operations, which would affect the smooth conveying of solid manure inside.

[0037] In this embodiment, the fertilizer application unit 2 includes a fertilizer cylinder 21, which is fixed to the lower end face of the mounting plate 14. A fixing cover 22 is detachably installed on one side of the fertilizer cylinder 21, and a feed hole 23 is opened on the upper end face of the fixing cover 22. A crushing disc 24 is rotatably connected to the center of the fertilizer cylinder 21, and a grinding plate 25 is fixed to the fertilizer cylinder 21 above the crushing disc 24 by bolts. Solid manure enters the fertilizer cylinder 21 through the feed hole 23 on the fixing cover 22. At this time, it can be spread on the surface of the crushing disc 24. When the crushing disc 24 is continuously rotating, the solid manure enters the gap between the crushing disc 24 and the grinding plate 25, thereby crushing and refining the larger pieces of solid manure in a bonded state, so as to accurately control the particle size of the final manure particles and ensure that it is suitable for spreading requirements.

[0038] A rotating shaft 26 is vertically fixed in the middle of the crushing disc 24, and a tube seat 4 is fixed on the upper end face of the mounting plate 14 directly above the fertilizer cylinder 21. The rotating shaft 26 is rotatably connected to the tube seat 4 through a bearing, and a main gear 27 is fixed at the end of the rotating shaft 26. A driving part (not shown in the figure) is provided inside the tube seat 4. The driving part is connected to the main gear 27 through gear meshing. The driving part can improve the rotational power of the crushing disc 24 so that the crushing disc 24 can perform crushing operations at different speeds.

[0039] A cover plate 28 is fixed below the fertilizer cylinder 21, and a fertilizer spreading plate 3 is coaxially rotatably arranged below the cover plate 28. The lower end of the rotating shaft 26 is connected to the fertilizer spreading plate 3. Multiple guide holes 29 are distributed around the lower end face of the fertilizer cylinder 21. The refined solid manure can be spread onto the fertilizer spreading plate 3 through the guide holes 29, so that the fertilizer spreading plate 3 can circumferentially spread the solid manure during the rotation operation.

[0040] In a preferred embodiment, a plurality of feeders 31 are distributed circumferentially on the fertilizer spreading disc 3, and each feeder 31 is fitted with a shaft pin 32 and is rotatably connected to the fertilizer spreading disc 3 through the shaft pin 32.

[0041] One end of the feeder 31 is fixed with a shaft assembly 34, and a baffle plate 35 is slidably connected to the shaft assembly 34; the baffle plate 35 can make the manure get sufficient centrifugal force and throw it out, ensuring the coverage of the manure spreading, and improving the spreading efficiency and effect.

[0042] The fertilizer spreading disc 3 is rotatably connected to an outer shaft ring 33 in the middle, and one end of each of the baffle plates 35 is connected to the outer shaft ring 33.

[0043] In this embodiment, the baffle plate 35 is made of high-elasticity stainless steel spring steel, which has a high-strength elastic deformation effect.

[0044] In this embodiment, an inner rod 41 is slidably connected inside the rotating shaft 26, and a positioning shaft 42 is vertically fixed on the side wall of the inner rod 41; a ring 43 is rotatably connected to the fertilizer spreading disc 3, and an outer shaft ring 33 is coaxially fixed outside the ring 43. An inclined guide groove is provided on the inner wall of the ring 43, and the positioning shaft 42 is slidably connected to the inclined guide groove. That is, when the inner rod 41 is axially sliding and adjusted, the positioning shaft 42 on its side wall can slide along the inclined guide groove, thereby driving the ring 43 and the outer shaft ring 33 to rotate accordingly. At this time, the baffle plate 35 can bend and deform, thereby changing the guiding trajectory of the manure. At the same time, the feeder 31 on the fertilizer spreading disc 3 can be deflected at a certain angle, thereby effectively adjusting the spreading coverage of the fertilizer spreading disc 3 while keeping the amount of solid manure spreading constant, so as to achieve the ideal coverage effect under different operating conditions.

[0045] In this embodiment, a guide cavity is provided in the center of the tube seat 4. A piston rod 44 is slidably connected in the guide cavity. The upper end of the inner rod 41 is rotatably connected to the piston rod 44. An air pump 45 is installed above the tube seat 4. The air pump 45 is sealed and connected to the guide cavity. The air pump 45 adjusts the air pressure in the guide cavity, thereby driving the inner rod 41 below the piston rod 44 to slide up and down.

[0046] In a preferred embodiment, a bevel gear 51 is fixed to one end of each mounting plate 14, and a coupling 5 is horizontally rotatably mounted between the outer protective plates 13. Both ends of the coupling 5 are fixed with bevel gears, which mesh with each of the bevel gears 51 for transmission. A transmission gear 52 is fixed on the coupling 5, and the coupling 5 is transmitted to an external power source through the transmission gear 52. Thus, when the external power source drives the coupling 5 to rotate for adjustment, the fertilizer disc unit 2 on each mounting plate 14 can generate a corresponding deflection and change the spreading angle.

[0047] In this embodiment, the two fertilizer tray units 2 are located on both sides of the seedling, and manure is spread at the same time to form a cross-coverage, which facilitates precise fertilization of the seedling; a spiral guide blade (not shown in the figure) is rotatably installed inside the manure box 1.

[0048] In this embodiment, a method for applying solid manure includes the following steps:

[0049] S1. Open the cover plate 11 of the manure box 1, add the pretreated solid manure into the manure box 1, and the solid manure enters the fertilizer cylinder 21 in each fertilizer tray unit 2 through the two discharge ports at the bottom of the manure box 1.

[0050] S2. Based on crop needs and field conditions, the coupling 5 is driven to rotate by an external power source, thereby adjusting the fertilization angle of the fertilizer application unit 2 to ensure that the manure can be evenly spread and cover both sides of the seedlings. At the same time, the flow rate of the conveying pipe 15 is adjusted according to the actual situation in order to control the amount of fertilizer applied each time.

[0051] S3. The two fertilizer application units 2 operate simultaneously, and solid manure can preferentially enter between the crushing disc 24 and the grinding plate 25. The solid manure is initially crushed and refined by the relative rotational motion of the crushing disc 24 and the grinding plate 25.

[0052] S4. The refined solid manure can be evenly spread on the spreading disc 3 through each feed hole 29, and the spreading disc 3 spreads the solid manure in the planting area while rotating.

[0053] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
