However, it should be clear to those skilled in the art that the utility model can also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to prevent unnecessary details from hindering the description of the utility model.
[0034] In conjunction with the instruction manual Figure 1 To Attachment Figure 4 It can be known that the raw material screening device for blended fertilizers provided by the utility model mainly includes the following parts or components: a processing box 10, a stirring component 20, a crushing component 50, a filtering component, a stirring shaft 21, and a lifting component 30.
[0035] In the utility model, two partitions 11 are arranged in parallel in the processing box 10, and the two partitions 11 divide the processing box 10 from top to bottom into a stirring chamber, a crushing chamber, and a filtering chamber. Two drop openings 111 are respectively arranged on the two partitions 11, and a sealing cover that can be opened and closed is arranged on the drop opening 111; the stirring component 20 is arranged in the stirring chamber for stirring the material, and the stirring chamber is provided with a first feeding port 101; the crushing component 50 is arranged in the crushing chamber for crushing the mixed material; the filtering component is arranged in the filtering chamber for screening the crushed material; wherein, the stirring component 20 specifically includes a stirring shaft 21, which is arranged in the stirring chamber and rotates under the drive of the driving component, and the stirring shaft 21 is provided with a stirring paddle 211, and the lifting component 30 is connected to the stirring shaft 21 for driving the stirring shaft 21 to rise and fall, and when the lifting component 30 drives the stirring shaft 21 to rise and fall, the driving component always drives the stirring shaft 21 to rotate.
[0036] The material is sent from the feed port 101 to the stirring chamber, and the driving component drives the stirring shaft 21 to rotate. The stirring shaft 21 stirs the material through the stirring paddle 211. When the driving component drives the stirring shaft 21 to rotate, the lifting component 30 drives the stirring shaft 21 to rise and fall at the same time, so that the stirring shaft 21 can be lifted and lowered while rotating. As the stirring shaft 21 rises and falls, the stirring paddle 211 can touch the materials in different areas of the container, effectively promoting the mixing of the materials and ensuring the uniformity and efficiency of the mixing process. After the stirring is completed, the sealing cover at the bottom of the stirring chamber is opened, and the materials fall into the crushing chamber through the drop opening 111 at the bottom of the stirring chamber. The crushing component 50 crushes the mixed materials. After the materials are crushed, the sealing cover at the bottom of the crushing chamber is opened, and the materials fall into the filter chamber through the drop opening 111 at the bottom of the crushing chamber. The filter component screens the materials.
[0037] The stirring paddle 211 is provided with a plurality of through holes 213 to reduce the resistance when clamping materials.
[0038] As an embodiment, in conjunction with the attached Figure 2 It can be seen that a rotatable rotating sleeve 22 is provided on the top of the stirring chamber, and the rotating sleeve 22 is sleeved on the stirring shaft 21 above the stirring chamber. The guide groove on the inner wall of the rotating sleeve 22 is adapted to the guide key 212 on the stirring shaft 21. The driving assembly includes a first motor 23, which is arranged on the processing box 10, and a first gear 231 is provided at its power output end, and the first gear 231 is meshed with the second gear 221 on the rotating sleeve 22. The lifting assembly 30 includes a first rotating shaft 31, which is vertically and rotatably arranged above the processing box 10. A third gear 312 is arranged at the lower end of the first rotating shaft 31, and the third gear 312 is meshed with the second gear 221 on the rotating sleeve 22; the optical axis 32 is arranged parallel to the first rotating shaft 31; the connecting plate 33 is horizontally arranged above the processing box 10, the middle part of the connecting plate 33 is connected to the upper end of the stirring shaft 21, the first end of the connecting plate 33 is threadedly connected to and penetrates the reciprocating thread section 311 on the first rotating shaft 31, and the second end of the connecting plate 33 is slidably connected to and penetrates the optical axis 32.
[0039] During stirring, the first motor 23 drives the first gear 231 to rotate, and the first gear 231 drives the rotating sleeve 22 to rotate through the second gear 221. The rotating sleeve 22 drives the stirring shaft 21 to rotate through the cooperation of the guide key 212 and the guide groove. The stirring shaft 21 stirs the material through the stirring paddle 211. When the rotating sleeve 22 rotates, the rotating sleeve 22 drives the first rotating shaft 31 to rotate. The first rotating shaft 31 is threadedly connected to the connecting plate 33 through the reciprocating thread section 311, and can drive the connecting plate 33 to reciprocate and rise and fall. The connecting plate 33 drives the stirring shaft 21 to rise and fall, and the stirring shaft 21 can be lifted and lowered while rotating. Compared with the prior art, as the stirring shaft 21 rises and falls, the stirring paddle 211 can touch the materials in different areas of the container, effectively promoting the mixing of the materials, and ensuring the uniformity and efficiency of the mixing process.
[0040] The reciprocating thread segment 311 is two thread grooves with the same pitch and opposite rotation directions, and the two ends are connected by a transition curve.
[0041] As an embodiment, in conjunction with the attached Figure 3 It can be seen that the filter assembly includes a filter plate 12, which is tiltedly arranged in the filter cavity. The lower end of the filter plate 12 is hinged to the inner wall of the filter cavity. A discharge port 45 is arranged on the inner wall of the filter cavity above the lower end of the filter plate 12. The filter plate 12 vibrates under the drive of the vibration assembly 40. The vibration assembly 40 includes a wheel disc 42, which is arranged in the filter cavity below the filter plate 12 and rotates under the drive of the second motor 41; the lifting rod 43 is arranged in the filter cavity below the filter plate 12, and the impact block 431 arranged at the upper end thereof contacts the lower surface of the higher end of the filter plate 12. The lower end of the lifting rod 43 passes through the support plate 44 in the filter cavity and is provided with a long slot hole 432. The long slot hole 432 is slidably connected with the guide column 421 eccentrically arranged on the wheel disc 42.
[0042] The second motor 41 drives the wheel 42 to rotate, and the wheel 42 drives the lifting rod 43 to rise and fall through the cooperation of the guide column 421 and the long slot hole 432. The impact block 431 on the lifting rod 43 impacts the lower surface of the higher end of the filter plate 12, effectively vibrating the filter plate 12, so that the material falls on the filter plate 12 and moves quickly to the discharge port 45. And the filtering effect is better, so that the qualified material falls from the filter plate 12 to the bottom of the filter chamber, and the larger pieces of material move from the filter plate 12 to the discharge port 45, and then are sent to the storage box from the discharge port 45, and the material in the storage box is taken out and sent to the crushing chamber through the feed port on the crushing chamber, and is crushed again by the crushing assembly 50.
[0043] As an embodiment, in conjunction with the attached Figure 4It can be seen that the crushing assembly 50 includes two crushing rollers 51 arranged in parallel, which are arranged in the crushing chamber, and the two fourth gears 52 on the two crushing rollers 51 are meshed with each other, and one of the crushing rollers 51 is driven by the third motor 53 to rotate. The third motor 53 drives one of the crushing rollers 51 to rotate, and one of the crushing rollers 51 drives the other crushing roller 51 to rotate through the meshing of the two fourth gears 52, which can effectively crush the material.
