Abstract
Description
[0001] This utility model relates to the field of fertilizer spreader technology, and more specifically, it relates to a storage box for a fertilizer spreader. Background Technology
[0002] A fertilizer spreader is an agricultural machine primarily used to evenly spread fertilizers (such as chemical fertilizers, organic fertilizers, or granular fertilizers) onto farmland to improve fertilization efficiency and crop yield. Fertilizer spreaders are typically equipped with a storage bin for fertilizer storage. Existing fertilizer spreader storage bins are usually fixed in structure, without adjustable storage space. When fertilizing large areas of farmland, the fixed capacity of the storage bin may require frequent stops for refilling due to limited capacity, reducing operational efficiency and increasing labor and time costs. Secondly, existing fertilizer spreader storage bins cannot adjust the discharge rate during use. Since different crops, soil conditions, and growth stages have varying fertilizer requirements, a fixed discharge pattern is insufficient to meet the demands of precision agriculture, thus reducing the overall flexibility and practicality of the device.

[0028] Please see Figure 1-5 A fertilizer spreader storage box includes a movable frame 1, a lower storage shell 2 fixedly mounted on the movable frame 1, a discharge pipe 3 fixedly mounted at the lower end of the lower storage shell 2, an upper storage shell 4 movably mounted inside the lower storage shell 2, a feed hopper 5 fixedly mounted on the upper storage shell 4, multiple limiting rods 6 fixedly mounted on the outer side of the lower storage shell 2, a support ring 7 fixedly mounted on the outer side of the upper storage shell 4, multiple screws 8 rotatably mounted on the support ring 7 via bearings, the lower ends of the screws 8 being threadedly connected to the limiting rods 6, a driven gear 9 fixedly mounted on the screws 8, a gear ring 10 rotatably mounted at the lower end of the support ring 7 via bearings, the gear ring 10 meshing with the driven gear 9, a first motor 11 fixedly mounted on the support ring 7, and a second... A motor 11 is driven by a screw 8 and is fixedly connected to a support ring 7. A third motor 20 is fixedly installed on the upper end of the upper storage shell 4. The drive end of the third motor 20 extends into the upper storage shell 4 and is fixedly installed with a square rod 21. A rotating shaft 22 is movably sleeved on the outer side of one end of the square rod 21. A bracket 23 is rotatably mounted on the rotating shaft 22 through a bearing. The bracket 23 is fixedly connected to the inside of the lower storage shell 2. Two first stirring rods 24 are fixedly mounted on the outer sides of the square rod 21 and the rotating shaft 22, respectively. Two second stirring rods 25 are fixedly mounted on the lower end of the rotating shaft 22 and extend into the discharge pipe 3. A sprinkling disc 26 is fixedly mounted on the lower end of the rotating shaft 22 through the first discharge plate 12 and the second discharge plate 14.
[0029] In this embodiment, when fertilization is required on a large area of farmland, the first motor 11 is started. The first motor 11 drives one of the screws 8 to rotate, and the screw 8 drives the driven gear 9 to rotate. Since the driven gear 9 is meshed with the gear ring 10, the gear ring 10 rotates, and the gear ring 10 drives the other driven gears 9 to rotate, causing multiple screws 8 to rotate simultaneously. Since the screws 8 are threadedly connected to the limiting rod 6, the screws 8 move away from the limiting rod 6 while rotating. The screws 8 drive the support ring 7 to move, and the support ring 7 drives the upper storage shell 4 to move, thus expanding the storage space between the upper storage shell 4 and the lower storage shell 2. At the same time, the upper storage shell 4 drives the third motor 20, the square rod 21, and the first stirring rod 24 on the square rod 21 to move, making the square rod 21 protruding from the rotating shaft 22 longer. Fertilizer can be placed into the storage space between the upper storage shell 4 and the lower storage shell 2 through the feed hopper 5. When it is necessary to stir and mix the stored fertilizer evenly, the third motor 20 is started. The third motor 20 drives the square rod 21 to rotate, the square rod 21 drives the rotating shaft 22 to rotate, and at the same time, multiple first stirring rods 24 rotate, so that the first stirring rods 24 stir and mix the stored fertilizer evenly.
[0030] Please see Figures 1-5 As an implementation method for adjusting the amount of material fed: the lower end of the discharge pipe 3 passes through the movable frame 1 and is fixedly provided with a first feeding plate 12. The first feeding plate 12 is provided with two first feeding ports 13. The lower end of the first feeding plate 12 is rotatably provided with a second feeding plate 14. The second feeding plate 14 is provided with two second feeding ports 15. A drive housing 16 is fixedly provided on the outside of the discharge pipe 3. A toothed belt 17 is fixedly provided on the outside of the second feeding plate 14 and extends into the drive housing 16. A second motor 18 is fixedly provided on the drive housing 16. The drive end of the second motor 18 extends into the drive housing 16 and is fixedly provided with a drive gear 19. The drive gear 19 is meshed with the toothed belt 17.
[0031] More specifically, when the amount of material to be fed needs to be adjusted, the second motor 18 is started, which drives the drive gear 19 to rotate. Since the drive gear 19 is meshed with the toothed belt 17, the toothed belt 17 rotates, which in turn drives the second feeding plate 14 to rotate. This adjusts the overlapping area of the second feeding port 15 and the first feeding port 13, thereby adjusting the amount of material to be fed. During the feeding process, the third motor 20 is started, which causes the first stirring rod 24 to rotate and simultaneously drives the second stirring rod 25 to rotate. This disturbs the stored fertilizer and the fertilizer in the discharge pipe 3, preventing fertilizer blockage. At the same time, the rotating shaft 22 drives the spreading disc 26 to rotate, thereby spreading the fertilizer that falls onto the spreading disc 26 onto the farmland. The spreading disc 26 is movably connected to both the first feeding plate 13 and the second feeding plate 14.
[0032] In summary, during the use or operation of the overall equipment: when fertilizing a large area of farmland, the first motor 11 is started, driving one of the screws 8 to rotate. The screw 8 drives the driven gear 9 to rotate. Since the driven gear 9 is meshed with the gear ring 10, the gear ring 10 rotates, driving the remaining driven gears 9 to rotate, causing multiple screws 8 to rotate simultaneously. Because the screws 8 are threadedly connected to the limiting rod 6, the screws 8 move away from the limiting rod 6 while rotating. The screws 8 drive the support ring 7 to move, and the support ring 7 drives the upper storage shell 4 to move, expanding the storage space between the upper storage shell 4 and the lower storage shell 2. At the same time, the upper storage shell 4 drives the third motor 20, the square rod 21, and the first stirring rod 24 on the square rod 21 to move, making the square rod 21 protruding from the rotating shaft 22 longer. Fertilizer can be placed into the storage space between the upper storage shell 4 and the lower storage shell 2 through the feed hopper 5. When it is necessary to stir and mix the stored fertilizer evenly, the third motor 20 is started. The third motor 20 drives the square rod 21 to rotate, the square rod 21 drives the rotating shaft 22 to rotate, and at the same time, multiple first stirring rods 24 rotate, so that the first stirring rods 24 stir and mix the stored fertilizer evenly.
[0033] When the amount of material to be fed needs to be adjusted, the second motor 18 is started. The second motor 18 drives the drive gear 19 to rotate. Since the drive gear 19 is meshed with the toothed belt 17, the toothed belt 17 rotates. The toothed belt 17 drives the second feeding plate 14 to rotate, thereby adjusting the overlapping area of the second feeding port 15 and the first feeding port 13, thus adjusting the amount of material to be fed. During the feeding process, the third motor 20 is started, causing the first stirring rod 24 to rotate, which in turn drives the second stirring rod 25 to rotate, thereby disturbing the stored fertilizer and the fertilizer in the discharge pipe 3 to prevent fertilizer blockage. At the same time, the rotating shaft 22 drives the spreading plate 26 to rotate, thereby spreading the fertilizer that falls onto the spreading plate 26 to the farmland. The spreading plate 26 is movably connected to the first feeding plate 13 and the second feeding plate 14.
[0034] The entire device is controlled by a controller on the fertilizer spreader. Since the controller is matched with common equipment and belongs to existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here.
[0035] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred.
