Description

Technical Field

[0001] This utility model relates to the field of mixing equipment technology, specifically an adjustable raw material quantitative mixing equipment for compound fertilizer production. Background Technology

[0002] Compound fertilizer refers to chemical fertilizer containing two or more major nutrients. Based on the number of nutrients contained, it can be divided into binary compound fertilizer (such as nitrogen-phosphorus fertilizer), ternary compound fertilizer (such as nitrogen-phosphorus-potassium fertilizer), and multi-element compound fertilizer (containing more micronutrients). Compound fertilizer is widely used in various crops, such as grain crops (rice, wheat) and cash crops (fruit trees, vegetables). Its application methods include basal fertilizer and topdressing. Basal fertilizer is usually applied before sowing or transplanting, while topdressing is used to supplement nutrients during crop growth. Because compound fertilizer production requires the addition of multiple raw materials, quantitative addition of these raw materials is necessary. Traditional addition methods are mostly manual, which has low efficiency. To improve this situation, an adjustable quantitative mixing device for compound fertilizer production is proposed.

[0003] As disclosed in the authorization announcement number CN112619535B, an adjustable raw material quantitative mixing device for compound fertilizer production includes a workbench with a vertical plate fixedly connected to one edge of the outer side of the workbench; a double-cavity hopper fixedly connected to one side of the vertical plate; a mixing hopper fixedly connected to one side of the workbench near the vertical plate, with one end of the mixing hopper circumferentially fixedly connected to the outer side of the double-cavity hopper; and a baffle plate rotatably connected to the discharge end of the double-cavity hopper, which cooperates with the double-cavity hopper.

[0004] Although it allows two raw materials to be poured into the chambers of the dual-chamber hopper separately, the raw material on the left falls out and drives the drive mechanism. When the drive mechanism contacts the front of the material control mechanism, the material control mechanism drives the left baffle to block the raw material on the left, while the right baffle does not block the raw material on the right. The raw material on the right falls out and mixes with the raw material on the left. In this way, there is no need for manual handling of the raw materials, thus avoiding hand discomfort.

[0005] However, it has not solved the problem that existing mixing equipment is not conducive to convenient linkage crushing of raw materials and circumferential rotation adjustment of different raw materials during use, which is not conducive to quantitative feeding of raw materials and affects the accuracy and flexibility of quantitative feeding of raw materials. Utility Model Content

[0006] The purpose of this utility model is to provide an adjustable raw material quantitative mixing device for compound fertilizer production, so as to solve the problems mentioned in the background art, which are not convenient for the linkage crushing of raw materials and the circumferential rotation adjustment of different raw materials, which are not conducive to the quantitative feeding of raw materials and affect the accuracy and flexibility of the quantitative feeding of raw materials.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an adjustable raw material quantitative mixing device for compound fertilizer production, comprising a drive base and a servo motor. The servo motor is installed on the inner wall of the drive base, and a worm gear is installed at the output end of the servo motor. A drive shaft is movably installed inside the drive base on one side of the worm gear, and the drive shaft extends to the outside of the drive base. A rotating disk is installed at the top of the drive shaft. A worm wheel is fitted on the surface of the drive shaft on one side of the worm gear, and the worm gear and the worm wheel mesh with each other. Multiple sets of crushing boxes with equal spacing are arranged inside the rotating disk, and the crushing boxes are fixedly connected to the rotating disk.

[0008] Preferably, each crushing box is equipped with two sets of drive shafts, and the drive shafts are movably connected to the crushing box.

[0009] Preferably, a crushing motor is installed on the outer wall of the crushing box, and the output end of the crushing motor is connected to a set of drive shafts.

[0010] Preferably, the surface of the drive shaft inside the crushing box is fitted with crushing rollers, and the two sets of crushing rollers mesh with each other.

[0011] Preferably, gears are fitted on the surface of the drive shaft outside the crushing box, and the two sets of gears mesh with each other.

[0012] Preferably, each of the crushing boxes is equipped with a material distribution box at the bottom, and each material distribution box is equipped with a discharge pipe at the bottom, with a solenoid valve installed inside the discharge pipe.

[0013] Preferably, each of the dispensing boxes has a connecting shaft movably installed inside, and each of the connecting shafts has a dispensing roller fitted on its surface.

[0014] Preferably, a drive motor is installed on the outer wall of each material distribution box, and the output end of the drive motor is connected to the connecting shaft.

[0015] Preferably, a left limiting frame and a right limiting frame are respectively installed on the inner walls of the distributing boxes on both sides of the distributing roller, and the distributing roller is slidably connected to the left limiting frame and the right limiting frame.

[0016] Preferably, the outer wall of the distributing roller is provided with multiple sets of grooves at equal intervals, and the volume of the multiple sets of grooves is equal.

[0017] Compared with the prior art, the beneficial effects of this utility model are: this mixing equipment not only realizes convenient linkage crushing of raw materials and circumferential rotation adjustment for feeding different raw materials, facilitating quantitative feeding of raw materials, but also improves the accuracy and flexibility of quantitative feeding of raw materials.

[0018] Various raw materials used in compound fertilizer production are poured into different crushing chambers. A crushing motor drives a set of drive shafts to rotate, which in turn drives a set of gears and a set of crushing rollers. Another set of drive shafts, via gears, drives another set of drive shafts, which in turn drives another set of crushing rollers. The crushing rollers break the raw materials into fine particles, which are then discharged to the bottom of the crushing chamber for subsequent production. When a specific amount of raw material needs to be added, the drive motor drives a connecting shaft to rotate, which in turn drives a distributing roller. The groove holds the raw material, and with the sliding cooperation between the distributing roller and the left and right limit frames, excess material is scraped off by the left limit frame. Because the volume of the grooves is equal, the amount of raw material added each time is fixed. After the distributing roller feeds the fixed amount of raw material into the discharge pipe, the solenoid valve is opened to discharge the raw material into the mixer. The mixer then mixes the raw material. This system achieves convenient, interconnected crushing of raw materials, facilitating quantitative feeding and improving the accuracy of raw material feeding.

[0019] A servo motor drives a worm gear to rotate, which in turn drives a drive shaft via a worm wheel. The drive shaft then rotates a rotating disc, a crushing box, a distribution box, and a discharge pipe, causing the crushing box containing other raw materials to rotate sequentially to the feeding port position. The above operation is then repeated to feed other raw materials into the mixer in sequence. This allows for convenient circumferential rotation adjustment to feed different raw materials, improving the flexibility of raw material feeding. Attached Figure Description

[0029] Example 1

[0030] Please see Figure 1-5 An embodiment of this utility model provides: an adjustable raw material quantitative mixing device for compound fertilizer production, including a drive base 1 and a servo motor 8. The servo motor 8 is installed on the inner wall of the drive base 1 and serves as a power drive. A worm gear 9 is installed at the output end of the servo motor 8. A drive shaft 7 is movably installed inside the drive base 1 on one side of the worm gear 9 and extends to the outside of the drive base 1. A rotating disk 4 is installed at the top of the drive shaft 7. A worm wheel 10 is fitted on the surface of the drive shaft 7 on one side of the worm gear 9 and the worm gear 9 and the worm wheel 10 mesh with each other. Multiple sets of crushing boxes 2 with equal spacing are arranged inside the rotating disk 4 and the crushing boxes 2 are fixedly connected to the rotating disk 4.

[0031] The device is installed on top of the mixer. Various raw materials for compound fertilizer production are poured into different crushing chambers 2. The crushing motor 3 is turned on, driving a set of drive shafts 6. These drive shafts 6 then drive a set of gears 20 and a set of crushing rollers 5. With the meshing of the two sets of gears 20, one set of drive shafts 6 drives another set of drive shafts 6, which in turn drives another set of crushing rollers 5. The meshing of the two sets of crushing rollers 5 breaks the raw materials into fine particles, which are then discharged to the bottom of the crushing chamber 2 for subsequent production. When a quantitative input of raw materials is required, the drive shafts 6 are turned on. The drive motor 13 drives the connecting shaft 14 to rotate, which in turn drives the distributing roller 15 to rotate. The groove 19 holds the raw material. With the sliding cooperation between the distributing roller 15 and the left limit frame 17 and the right limit frame 18, excess raw material is scraped off by the left limit frame 17. Since the volume of the groove 19 is equal, the amount of raw material fed in each time is fixed. After the distributing roller 15 feeds the fixed amount of raw material into the discharge pipe 16, the solenoid valve 11 is opened to discharge the raw material into the mixer. Then the mixer mixes the raw material, realizing convenient linkage crushing of raw materials, facilitating the quantitative feeding of raw materials, and improving the accuracy of raw material feeding.

[0032] The crushing box 2 is equipped with two sets of drive shafts 6 inside, and the drive shafts 6 are movably connected to the crushing box 2.

[0033] Crushing motors 3 are installed on the outer wall of the crushing box 2. The crushing motors 3 serve as power drives, and the output end of the crushing motors 3 is connected to a set of transmission shafts 6. Crushing rollers 5 are fitted on the surface of the transmission shafts 6 inside the crushing box 2, and the two sets of crushing rollers 5 mesh with each other.

[0034] Gears 20 are fitted on the surface of the drive shaft 6 outside the crushing box 2, and the two sets of gears 20 mesh with each other. A material distribution box 12 is installed at the bottom of the crushing box 2, and a discharge pipe 16 is installed at the bottom of the material distribution box 12. A solenoid valve 11 is installed inside the discharge pipe 16.

[0035] The material distribution box 12 is equipped with a connecting shaft 14 inside each of the material distribution boxes 12. The surface of the connecting shaft 14 is fitted with a material distribution roller 15. The outer wall of the material distribution box 12 is equipped with a drive motor 13, which serves as a power drive and the output end of the drive motor 13 is connected to the connecting shaft 14.

[0036] Left limit frame 17 and right limit frame 18 are respectively installed on the inner walls of the material distribution box 12 on both sides of the material distribution roller 15, and the material distribution roller 15 is slidably connected to the left limit frame 17 and right limit frame 18. Multiple sets of grooves 19 with equal spacing are installed on the outer wall of the material distribution roller 15, and the volume of the multiple sets of grooves 19 is equal.

[0037] When other raw materials need to be quantitatively added, the servo motor 8 is turned on, which drives the worm gear 9 to rotate. Under the mutual meshing of the worm gear 9 and the worm wheel 10, the worm gear 9 drives the drive shaft 7 to rotate through the worm wheel 10. The drive shaft 7 drives the rotating disk 4, the crushing box 2, the material distribution box 12, and the discharge pipe 16 to rotate, so that the crushing box 2 containing other raw materials rotates to the feeding port position in sequence. Then, the above operation is repeated to feed other raw materials into the mixer in sequence. This realizes convenient circumferential rotation adjustment for feeding different raw materials and improves the flexibility of raw material feeding.

[0038] Work steps

[0039] The device is installed on top of the mixer. Various raw materials for compound fertilizer production are poured into different crushing boxes 2. A crushing motor 3 drives a set of drive shafts 6, which in turn drive a set of gears 20 and a set of crushing rollers 5. With the meshing of the two sets of gears 20, one set of drive shafts 6 drives another set of drive shafts 6 via the gears 20. This other set of drive shafts 6 then drives another set of crushing rollers 5. With the meshing of the two sets of crushing rollers 5, the raw materials are crushed into fine particles and discharged to the bottom of the crushing box 2 for subsequent production. When a quantitative input of raw materials is required, a drive motor 13 drives a connecting shaft 14, which in turn drives a distributing roller 15. The material is collected in a groove 19. The distributing roller 15 interacts with the left limiting frame 17 and the right limiting frame 18. With the sliding engagement of 8, excess raw material is scraped off by the left limit frame 17. Since the volume of the grooves 19 is equal, the raw material added each time is quantitative. After the quantitative raw material is fed into the discharge pipe 16 by the distributing roller 15, the solenoid valve 11 is opened to discharge the raw material into the mixer. Then the mixer mixes the raw material. When other raw materials need to be quantitatively added, the servo motor 8 drives the worm 9 to rotate. The worm 9 drives the drive shaft 7 to rotate through the worm wheel 10. The drive shaft 7 drives the rotating disk 4, crushing box 2, distributing box 12 and discharge pipe 16 to rotate, so that the crushing box 2 containing other raw materials rotates to the feeding port position in sequence. Then the above operation is repeated to feed other raw materials into the mixer in sequence. The above is the complete usage of the adjustable raw material quantitative mixing equipment for compound fertilizer production.

[0040] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
