Description

Technical Field

[0001] This utility model relates to the field of fertilizer production technology, and in particular to a quantitative feeding mechanism for fertilizer production. Background Technology

[0002] Fertilizers are substances that provide one or more essential nutrients for plants, improve soil properties, and enhance soil fertility. They are one of the material foundations of agricultural production. They mainly include ammonium phosphate fertilizers, water-soluble fertilizers containing macronutrients, fertilizers containing micronutrients, bio-fertilizers, organic fertilizers, and multi-dimensional energy-concentrating organic fertilizers.

[0003] According to the utility model patent application number 202120205971.5 for a quantitative conveying device for compound fertilizer production, the solution is to drive the material dividing plate to rotate by a drive motor, so that the two adjacent outer dividing plates in the material dividing plate collect an equal amount of fertilizer and push the fertilizer to the discharge port position on one side of the feeding cylinder, so that the fertilizer leaks out through the discharge pipe, thereby realizing the function of quantitative feeding.

[0004] However, when the outer dividing plate is rotated by the ring to scrape and convey the raw material in equal quantities, the outer dividing plate and the inner wall of the feeding cylinder must fit together to avoid gaps that could cause material leakage. This results in wear on one side of the outer dividing plate and the raw material being scraped and conveyed by the outer dividing plate. The raw material is also prone to squeezing and rubbing against each other, causing breakage and affecting the quality of subsequent feed production. Therefore, we propose a quantitative feeding mechanism for fertilizer production. Utility Model Content

[0005] The present invention aims to solve the technical problems existing in the prior art and provide a quantitative feeding mechanism for fertilizer production.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a quantitative feeding mechanism for fertilizer production, comprising a feeding cylinder, a bottom support, a cover plate, a feeding hopper, and a conveying pipe. A main shaft is rotatably mounted on the bottom side inside the feeding cylinder. A drive ring is fixedly installed on the outside of the main shaft via a support shaft. Several sets of feeding plates are fixedly installed around the drive ring. A motor is fixedly mounted at the bottom of the feeding cylinder. The output shaft of the motor is driven and connected to a drive shaft fixedly connected to the lower end of the main shaft. A discharge groove is opened on the bottom side inside the feeding cylinder. A discharge hopper is fixedly installed at the bottom of the feeding cylinder. Every two sets of support shafts are sealed and connected by a closing plate. A guide plate is rotatably connected to one side of the bottom of each feeding plate via a hinge. A connecting seat is fixedly installed on one side of the feeding plate. A circular groove is opened inside the connecting seat, and a spring fixedly connected to the guide plate is fixedly connected to the inner side of the circular groove.

[0007] Preferably, a sealed space is formed between every two sets of the feeding plates and the closing plate. When the motor starts and drives the drive ring outside the main shaft to rotate through the drive shaft, every two sets of feeding plates outside the drive ring cooperate with the closing plate to drive the raw material in a scraping conveying state.

[0008] Preferably, when the raw material between each pair of feeding plates and closing plates is rotated and scraped inside the feeding cylinder to the discharge trough, the raw material between each pair of feeding plates and closing plates is in a downward squeezing discharge state against the two sets of guide plates.

[0009] Preferably, after the two sets of guide plates open downward to discharge material, when there is no extrusion pressure above the two sets of guide plates, the two sets of guide plates are elastically reset upward by springs.

[0010] Preferably, the bottom of the guide plate is integrally formed with an extension, the bottom of the extension is provided with an arc-shaped groove, a round shaft is fixedly installed inside the arc-shaped groove, and a support roller is rotatably sleeved on the outside of the round shaft.

[0011] Preferably, the outer side of the support roller is in close contact with the bottom side of the inside of the feeding cylinder. When the two sets of feeding plates drive the raw material on the guide plate to rotate and move, the support roller at the bottom of the guide plate and the bottom side of the inside of the feeding cylinder are in a supporting rolling state.

[0012] Preferably, the feed hopper and the conveying pipe are both integrally formed with a connecting pipe end, and two sets of connecting pipe ends are provided between the two sets of connecting pipe ends. The two sets of connecting pipe ends are fixedly connected and fitted by a dustproof bag. The connecting pipe end and the connecting pipe end are provided with screw holes at corresponding positions inside, and bolts are threaded into the screw holes.

[0013] Preferably, when the raw material is conveyed into the feed hopper through the conveying pipe, the dustproof bags between the two sets of connecting pipe ends are in a sealed dustproof state to prevent dust generated by the raw material.

[0014] This utility model provides a quantitative feeding mechanism for fertilizer production. It has the following beneficial effects:

[0015] 1. A quantitative feeding mechanism for fertilizer production, wherein the two sets of feeding plates are sealed together by a closing plate, and a sealed holding space is formed between the two sets of feeding plates and the closing plate. When the conveying pipe transports the material through the feeding hopper to the space between the two sets of feeding plates, the two sets of feeding plates, the closing plate, and the guide plate can store the raw material, avoiding direct contact between the raw material and the inner side of the feeding cylinder, and there is also a gap between the feeding plate and the inner side of the feeding cylinder. When the motor starts and drives the feeding plate outside the drive ring to rotate, the two sets of feeding plates can drive the raw material to move directly. When the guide plate between the two sets of feeding plates moves to the discharge chute position, when there is no support at the bottom of the two sets of guide plates, the guide plates can flip down and open to discharge the material under the pressure of the weight of the raw material. After the discharge is completed, the guide plate can automatically reset by the spring. In this way, the raw material between the feeding plates can avoid friction, compression, and scraping, thereby improving the quality of subsequent feed production.

[0016] 2. A quantitative feeding mechanism for fertilizer production, wherein a dustproof bag is installed between the conveying pipe and the feeding hopper, and the connecting pipe ends on both sides of the dustproof bag are respectively connected and fixed to the connecting pipe ends on the conveying pipe and the feeding hopper. When the conveying pipe is conveying raw materials, the dust generated by the raw materials can be prevented from scattering through the dustproof bag, thereby reducing the scattering of dust and improving the environmental protection effect.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example: A quantitative feeding mechanism for fertilizer production, such as... Figures 1-7As shown, the device includes a feeding cylinder 1, a bottom support 2, a cover plate 3, a feeding hopper 4, and a conveying pipe 23. A main shaft 5 is rotatably mounted on the bottom side inside the feeding cylinder 1. A drive ring 7 is fixedly mounted on the outside of the main shaft 5 via a support shaft 6. Several sets of feeding plates 8 are fixedly mounted around the drive ring 7. A motor 9 is fixedly mounted at the bottom of the feeding cylinder 1. The output shaft of the motor 9 is connected to a drive shaft 10 fixedly connected to the lower end of the main shaft 5. A discharge trough 11 is opened on the bottom side inside the feeding cylinder 1. A discharge hopper 12 is fixedly mounted at the bottom of the feeding cylinder 1. Every two sets of support shafts 6 are sealed and connected by a closing plate 13. A guide plate 15 is rotatably connected to one side of the bottom of the feeding plate 8 via a hinge 14. A connecting seat 16 is fixedly mounted on one side of the feeding plate 8. The connecting seat 16 has a circular groove 17 inside. A spring 18, which is fixedly connected to the guide plate 15, is fixedly connected to the inside of the circular groove 17. An extension 19 is integrally formed at the bottom of the guide plate 15. An arc groove 20 is formed at the bottom of the extension 19. A round shaft 21 is fixedly installed inside the arc groove 20. A support roller 22 is rotatably sleeved on the outside of the round shaft 21. One end of the feed hopper 4 and the conveying pipe 23 is integrally formed with a connecting pipe end 24. Two sets of connecting pipe ends 25 are provided between the two sets of connecting pipe ends 24. The two sets of connecting pipe ends 25 are fixedly connected and fitted by a dustproof bag 26. Screw holes 27 are opened at corresponding positions inside the connecting pipe end 24 and the connecting pipe end 25. Bolts 28 are threaded inside the screw holes 27.

[0030] Furthermore, a sealed space is formed between each pair of feeding plates 8 and the closing plate 13. When the motor 9 starts and drives the drive ring 7 outside the main shaft 5 to rotate through the drive shaft 10, each pair of feeding plates 8 outside the drive ring 7 cooperates with the closing plate 13 to drive the raw material in a scraping conveying state.

[0031] Furthermore, when the raw material between each pair of feeding plates 8 and closing plates 13 is located inside the feeding cylinder 1 and rotated and scraped to the discharge trough 11, the raw material between each pair of feeding plates 8 and closing plates 13 is in a downward squeezing discharge state on the two sets of guide plates 15.

[0032] Furthermore, after the two sets of guide plates 15 open downwards to discharge material, when there is no extrusion pressure above the two sets of guide plates 15, the two sets of guide plates 15 are in an elastic upward reset state through the spring 18.

[0033] Furthermore, the outside of the support roller 22 is in close contact with the bottom inside of the feeding cylinder 1. When the two sets of feeding plates 8 drive the raw material on the guide plate 15 to rotate and move, the support roller 22 at the bottom of the guide plate 15 and the bottom inside of the feeding cylinder 1 are in a supporting rolling state.

[0034] Furthermore, when the raw material is conveyed into the feed hopper 4 inside the conveying pipe 23, the dustproof bags 26 between the two sets of connecting pipe ends 25 are in a sealed dustproof state against the dust generated by the raw material.

[0035] The working principle of this utility model:

[0036] The two sets of feeding plates 8 are sealed together by a closing plate 13, forming a sealed holding space between them. When the conveying pipe 23 conveys the material through the feed hopper 4 to the space between the two sets of feeding plates 8, the two sets of feeding plates 8, the closing plate 13, and the guide plate 15 can store the raw material, preventing direct contact between the raw material and the inside of the feeding cylinder 1. There is also a gap between the feeding plates 8 and the closing plate 13 and the inside of the feeding cylinder 1. When the motor 9 starts and drives the feeding plates 8 outside the drive ring 7 to rotate, the two sets of feeding plates 8 can move the raw material directly. When the guide plate 15 between the two sets of feeding plates 8 moves to the position of the discharge trough 11, the bottom of the two sets of guide plates 15, without any support, can flip down and open to discharge the material under the pressure of the raw material weight. After the discharge is completed, the guide plate 15 can automatically reset by the spring 18. In this way, the raw material between the feeding plates 8 can avoid friction, compression, and scraping.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
