Description

Technical Field

[0001] This utility model belongs to the field of agricultural machinery technology, specifically a granular fertilizer spreader with an adjustable discharge port and a scraper feeding mechanism. Background Technology

[0002] With the continuous development of large-scale and intensive agricultural planting models, the efficient application of granular fertilizers has become one of the key links in improving agricultural production efficiency. In various planting scenarios such as farmland and orchards, different types of granular fertilizers need to be adapted to achieve integrated operations of stable delivery, precise quantity control, and uniform spreading.

[0003] Existing technologies still have the following shortcomings: Existing granular fertilizer spreading equipment generally suffers from uneven feeding, easily leading to fertilizer accumulation and residue; the output control precision is insufficient, making it difficult to achieve continuous and stable feeding; the design of the spreading mechanism is unreasonable, resulting in uneven fertilizer distribution and difficulty in controlling the range. Furthermore, the poor coordination of various functional components leads to low overall operating efficiency, not only affecting fertilization effects but also causing significant fertilizer waste. Its practicality and adaptability are insufficient to meet diverse spreading needs. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides a granular fertilizer spreader with an adjustable discharge port and a scraper feeding mechanism, which solves the problems existing in the prior art.

[0021] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0022] like Figures 1-5 As shown, this utility model provides a technical solution:

[0023] A pellet fertilizer spreader with an adjustable discharge port and a scraper feeding mechanism includes:

[0024] A flat support platform 1, a hopper 3, a feeding box shell 2 fixedly connected to the flat support platform 1, a hopper 3 fixedly connected to the flat support platform 1, and a first motor 4 installed on the flat support platform 1;

[0025] A first sprocket 5 is coaxially fixedly connected to the output shaft of the first motor 4. A second sprocket 8 is rotatably connected inside the outer shell 2 of the feeding box. Spiral blades 9 are coaxially fixedly connected to both ends of the second sprocket 8. Two chains 6 are sleeved between the first sprocket 5 and the second sprocket 8. Multiple partitions 7 are fixedly connected between the two chains 6. A uniform material spreading mechanism is provided at the bottom of the flat plate support platform 1.

[0026] Specifically, the fertilizer to be scattered is poured into the hopper 3. At this time, the first motor 4 is driven, causing the first sprocket 5, which is coaxially fixed to it, to rotate. This causes the two chains 6 on it to move as well. The chains 6 drive the second sprocket 8. The multiple partitions 7, which are fixedly connected between the two chains 6, also rotate with the rotation of the two chains 6. This causes the fertilizer falling into the outer shell 2 of the feeding box to be pushed forward with the movement of the partitions 7. Since the two spiral blades 9 are coaxially fixed to the first sprocket 5, the two spiral blades 9 also rotate when the first sprocket 5 rotates. The fertilizer falls on the top of the two spiral blades 9 and the first sprocket 5. Therefore, when the fertilizer falls, the two spiral blades 9 can make the waste material move towards the middle and be pushed by the partitions 7.

[0027] The uniform material spreading mechanism includes: a spreading disc 15, which is fixedly connected to the bottom of the flat plate support platform 1; a first pulley 10 is coaxially fixedly connected to the output shaft of the first motor 4; a star-shaped discharge machine housing 14 is fixedly connected to the bottom of the flat plate support platform 1; an impeller 13 is provided inside the star-shaped discharge machine housing 14; a second pulley 11 is coaxially fixedly connected to the rotating shaft of the impeller 13; a belt 12 is sleeved between the first pulley 10 and the second pulley 11; a second motor 17 is provided at the bottom of the spreading disc 15; and a centrifugal scraper 16 is coaxially fixedly connected to the output shaft of the second motor 17.

[0028] Specifically, when fertilizer falls from the feed box housing 2 into the star-shaped discharge machine housing 14, a second pulley 11 is coaxially fixedly connected to the impeller 13 inside the star-shaped discharge machine housing 14. A belt 12 is sleeved between the second pulley 11 and the first pulley 10 coaxially fixedly connected to the output shaft of the first motor 4. Thus, when the first motor 4 is running, the impeller 13 also rotates. Under the rotation of the impeller 13, the device continuously and evenly discharges fertilizer. The fertilizer discharged from the star-shaped discharge machine housing 14 falls onto the spreading disc 15. Since the spreading disc 15 is fixedly connected to the bottom of the flat support platform 1 and is equipped with a baffle plate, the spreading can be done in only one direction. The second motor 17 at the bottom drives the centrifugal scraper 16, which is coaxially fixedly connected to its output shaft, to rotate, thereby evenly spreading the fertilizer on it.

[0029] The working principle of this utility model is as follows:

[0030] First, the fertilizer to be scattered is poured into the hopper 3. At this time, the first motor 4 is driven, causing the first sprocket 5, which is fixedly connected to it on the same axis, to rotate. This causes the two chains 6 on it to move as well. The chains 6 drive the second sprocket 8. The multiple partitions 7, which are fixedly connected between the two chains 6, also rotate as the two chains 6 rotate. This causes the fertilizer falling into the outer shell 2 of the feeding box to be pushed forward by the movement of the partitions 7. Since the two spiral blades 9 are fixedly connected to the first sprocket 5 on the same axis, the two spiral blades 9 also rotate when the first sprocket 5 rotates. The fertilizer falls on the top of the two spiral blades 9 and the first sprocket 5. Therefore, when the fertilizer falls, the two spiral blades 9 can make the waste material move towards the middle and be pushed forward by the partitions 7.

[0031] Next, when the fertilizer falls from the feed box housing 2 into the star-shaped discharge machine housing 14, the impeller 13 inside the star-shaped discharge machine housing 14 is coaxially fixedly connected to the second pulley 11. A belt 12 is sleeved between the second pulley 11 and the first pulley 10 coaxially fixedly connected to the output shaft of the first motor 4. Thus, when the first motor 4 is running, the impeller 13 also rotates. Under the rotation of the impeller 13, the device continuously and evenly discharges the fertilizer. The fertilizer discharged from the star-shaped discharge machine housing 14 falls onto the spreading disc 15. Since the spreading disc 15 is fixedly connected to the bottom of the flat support platform 1 and is equipped with a baffle plate, the spreading can be done in only one direction. The second motor 17 at the bottom drives the centrifugal scraper 16, which is coaxially fixedly connected to its output shaft, to rotate, thereby evenly spreading the fertilizer on it.

[0032] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
