Abstract
Description
Technical Field
[0001] This utility model relates to the field of agricultural machinery technology, and in particular to a uniform fertilizer spreading device for a rice side-deep fertilizer applicator. Background Technology
[0002] In the process of rice cultivation, scientific fertilization is a key link to improve yield and quality. Side deep fertilization technology can accurately apply fertilizer to the soil 3-5cm deep to the side of the rice roots, which can effectively reduce fertilizer volatilization and loss, improve fertilizer utilization, and reduce pollution to the water environment. It has become an important technical means for modern rice cultivation.
[0003] Chinese Patent Publication No. CN218388678U discloses a uniform fertilizer spreading device for a rice side-deep fertilizer applicator, including a fertilizer discharge mechanism. The fertilizer discharge mechanism includes a housing with a feeding seat at the top and a feeding channel inside the feeding seat. The other end of a discharge pipe is connected to the feeding channel. A blocking block for sealing the outlet of the discharge pipe is slidably disposed in the feeding channel. The position of the blocking block in the feeding channel is adjusted by a lifting component. The fertilizer discharge mechanism also includes a uniform fertilizer component, which is coaxially and rotatably disposed in the housing. The uniform fertilizer component is used to measure fertilizer, and in conjunction with the rotation of the uniform fertilizer component, the measured fertilizer is discharged through the discharge pipe, avoiding the problem of excessive or insufficient fertilizer application affecting the fertilization effect.
[0004] The aforementioned patent documents still have the following defects in practice:
[0005] After the fertilizer enters through the feed channel, it needs to be guided by the guide plate and returned through the receiving channel. If the fertilizer particles are of uneven size, blockage may occur in the receiving channel, affecting the overall conveying efficiency. The discharge pipe relies solely on gravity to discharge the fertilizer. If the fertilizer has high moisture content or large particles, it is easy to stagnate in the pipe. Utility Model Content
[0006] The main purpose of this utility model is to provide a uniform fertilizer spreading device for a rice side-deep fertilizer applicator, which can effectively solve the problems mentioned above.
[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0008] A uniform fertilizer spreading device for a rice side-deep fertilizer applicator includes two fixed frames (I), with a fertilizer bin fixedly connected to the lower end of both fixed frames. A fixed plate is fixedly connected to the upper left end of the fertilizer bin, and a transmission mechanism is fixedly connected to the lower end of the fixed plate. Fixed frames (II) are fixedly connected to both the left and right sides of the lower end of the fertilizer bin. A transmission rod is rotatably connected to the end of each fixed frame (II) away from the fertilizer bin. Several feeding hoppers are fixedly connected to the lower end of the fertilizer bin, and a spreading mechanism is fixedly connected to the lower end of each feeding hopper. A control mechanism is fixedly connected to the upper part of the spreading mechanism.
[0009] Preferably, the inner cavity of some of the feeding hoppers communicates with the inner cavity of the fertilizer bin.
[0010] Preferably, the material spreading mechanism includes a material conveying pipe, the upper end of which is fixedly connected to the lower end of the feeding hopper, and the end of the material conveying pipe away from the feeding hopper is fixedly connected to a housing, and the lower end of the housing is fixedly connected to a discharge pipe.
[0011] Preferably, the material spreading mechanism further includes a material conveying block, the inner surface of which is fixedly connected to the outer surface of the transmission rod.
[0012] Preferably, the outer surface of the conveying block is in contact with the inner surface of the outer shell, the inner surface of the outer shell is in communication with the inner surface of the conveying pipe, and the inner surface of the outer shell is in communication with the inner surface of the discharge pipe.
[0013] Preferably, the control mechanism includes a gear, the inner surface of which is rotatably connected to the upper rear end of the outer casing. A connecting plate is rotatably connected to the upper rear end of the gear. An L-shaped connecting plate is rotatably connected to the end of the connecting plate away from the gear. A connecting rod is fixedly connected to the end of the L-shaped connecting plate away from the connecting plate. A cylindrical block is fixedly connected to the lower end of the connecting rod. A support frame is slidably connected to the outer surface of the vertical end of the L-shaped connecting plate and the outer surface of the connecting rod. The end of the support frame away from the connecting rod is fixedly connected to the conveying pipe.
[0014] Preferably, the control mechanism further includes a second gear, the inner surface of which is fixedly connected to the outer surface of the transmission rod, and the first gear meshes with the second gear.
[0015] Preferably, the transmission mechanism includes a motor, the upper end of which is fixedly connected to the lower end of the fixed plate, a pulley one is fixedly connected to the outer surface of the output end of the motor, a transmission belt is covered on the outer surface of the pulley one, a pulley two is wound around the end of the transmission belt away from the pulley one, and the inner surface of the pulley two is connected to the transmission rod.
[0016] Compared with the prior art, the present invention has the following beneficial effects:
[0017] 1. In this embodiment, the linkage between the spreading mechanism and the control mechanism is set up to realize quantitative delivery and precise application of fertilizer. In the spreading mechanism, the storage bin formed by the conveying block and the outer shell rotates synchronously with the transmission rod. In conjunction with the periodic opening and closing of the cylindrical block in the control mechanism (the meshing transmission of gear one and gear two causes the cylindrical block to move up and down), the amount of fertilizer falling into the storage bin each time is consistent, avoiding the problem of "over-application" or "under-application" in traditional fertilization. The periodic lifting and lowering of the cylindrical block, plus the ratio of gear one to gear two of 1:4, also ensures continuous material delivery without fertilizer crowding and clumping. This makes the amount of fertilizer applied to the rice roots at a depth of 3-5cm uniform and stable, which is conducive to the balanced absorption of nutrients by rice and improves yield and quality.
[0018] 2. In this embodiment, a cooperative structure between the conveying pipe and the conveying block is set up: the outer surface of the conveying block is in close contact with the inner surface of the outer shell. When rotating, it can generate a pushing force on the fertilizer, avoiding the fertilizer from being stuck in the conveying pipe or the outer shell. At the same time, the gradually narrowing design of the discharge pipe generates a slight pushing force, further preventing blockage and ensuring continuous and efficient fertilizer delivery.

The device is characterized in that: a fertilizer bin 2 is fixedly connected to the lower end of both fixed frames 1; a fixed plate 3 is fixedly connected to the upper left end of the fertilizer bin 2; a transmission mechanism 4 is fixedly connected to the lower end of the fixed plate 3; fixed frames 9 are fixedly connected to both the left and right sides of the lower end of the fertilizer bin 2; a transmission rod 5 is rotatably connected to the end of the two fixed frames 9 away from the fertilizer bin 2; a plurality of feeding hoppers 8 are fixedly connected to the lower end of the fertilizer bin 2; a spreading mechanism 6 is fixedly connected to the lower end of the feeding hoppers 8; a control mechanism 7 is fixedly connected to the upper part of the spreading mechanism 6; and the inner cavity of the plurality of feeding hoppers 8 communicates with the inner cavity of the fertilizer bin 2.
[0027] The device is connected to the fertilizer machine through the fixed frame 1 and the attachment of the fertilizer machine. The attachment is fixed to the fixed frame 1 or drives the fixed frame 1 to adjust its position.
[0028] In this embodiment, during implementation, the fixed frame 1 is connected to the fertilizer applicator, the fertilizer bin 2 is filled with fertilizer, the transmission mechanism 4 is started, the transmission mechanism 4 drives the transmission rod 5 and the spreading mechanism 6 to operate, the fertilizer in the fertilizer bin 2 will fall into the control mechanism 7 through the feeding hopper 8, and then the fertilizer will be spread into the rice paddy at a depth of 3-5cm.
[0029] To drive the transmission rod 5 to rotate, refer to... Figure 5 The transmission mechanism 4 includes a motor 41. The upper end of the motor 41 is fixedly connected to the lower end of the fixed plate 3. A pulley 42 is fixedly connected to the outer surface of the output end of the motor 41. A transmission belt 43 is covered on the outer surface of the pulley 42. A pulley 44 is wound around the end of the transmission belt 43 away from the pulley 42. The inner surface of the pulley 44 is fixedly connected to the outer surface of the transmission rod 5.
[0030] During implementation, motor 41 is started, which drives pulley 42 to rotate. Pulley 42 drives pulley 44 to rotate via transmission belt 43, and pulley 44 drives transmission rod 5 to rotate.
[0031] Example 2: For the purpose of depth measurement and feeding of rice, please refer to... Figure 3 The material spreading mechanism 6 includes a material conveying pipe 61, the upper end of which is fixedly connected to the lower end of the feeding hopper 8. The end of the material conveying pipe 61 away from the feeding hopper 8 is fixedly connected to a housing 62. The lower end of the housing 62 is fixedly connected to a discharge pipe 64. The material spreading mechanism 6 also includes a material conveying block 63, the inner surface of which is fixedly connected to the outer surface of the transmission rod 5. The outer surface of the material conveying block 63 is in contact with the inner surface of the housing 62. The inner surface of the housing 62 communicates with the inner surface of the material conveying pipe 61 and the inner surface of the discharge pipe 64.
[0032] During implementation, fertilizer falls into the conveying pipe 61 through the feeding hopper 8, and then into the outer shell 62 through the conveying pipe 61. The outer surface of the conveying block 63 has four arc-shaped notches, which together with the outer shell 62 form four storage bins. The fertilizer falls into the storage bins through the upper part of the conveying pipe 61, and then the rotation of the conveying block 63 carries the fertilizer to the lower part of the outer shell 62. It then falls into the soil through the discharge pipe 64. The diameter of the discharge pipe 64 gradually narrows from the inlet to the outlet, and a slight forward thrust is generated due to compression to ensure that the fertilizer can be discharged smoothly from the outlet and avoid stagnation in the pipe due to insufficient gravity.
[0033] For further details, please refer to [link / reference]. Figure 4 The control mechanism 7 includes a gear 71, the inner surface of which is rotatably connected to the upper rear end of the housing 62. A connecting plate 72 is rotatably connected to the upper rear end of the gear 71. An L-shaped connecting plate 73 is rotatably connected to the end of the connecting plate 72 away from the gear 71. A connecting rod 74 is fixedly connected to the end of the L-shaped connecting plate 73 away from the connecting plate 72. A cylindrical block 75 is fixedly connected to the lower end of the connecting rod 74. A support frame 77 is slidably connected to the outer surface of the vertical end of the L-shaped connecting plate 73 and the outer surface of the connecting rod 74. The end of the support frame 77 away from the connecting rod 74 is fixedly connected to the conveying pipe 61. The control mechanism 7 also includes a gear 76, the inner surface of which is fixedly connected to the outer surface of the transmission rod 5. Gear 71 and gear 76 mesh.
[0034] During implementation, transmission rod 5 drives gear 2 76 to rotate, gear 2 76 drives gear 1 71 to rotate, gear 1 71 drives L-shaped connecting plate 73 to move up and down through connecting plate 1 72, L-shaped connecting plate 73 drives connecting rod 74 and cylindrical block 75 to move up and down, support frame 77 limits L-shaped connecting plate 73 and connecting rod 74, cylindrical block 75 moves downward to block the outlet of conveying pipe 61, and after moving upward, the fertilizer in conveying pipe 61 will fall into the storage bin formed by conveying block 63 and outer shell 62, gear 1 71 The diameter is one-quarter of the diameter of gear 76. This ensures that when the storage bin is directly opposite the cylindrical block 75, the cylindrical block 75 is at its highest position, and a large amount of fertilizer in the conveying pipe 61 falls into the storage bin. As the storage bin is gradually moved away, the cylindrical block 75 moves down to its lowest point. At this time, the storage bin is just moved away and full. Then the cylindrical block 75 begins to move upward, and the fertilizer in the conveying pipe 61 accumulates on the upper part of the outer shell 62. When the next storage bin appears, the accumulated material will fall into the storage bin. This cycle continues, ensuring that the amount of material discharged each time is the same, thus guaranteeing uniform distribution.
