Description

Technical Field

[0001] The utility model relates to the technical field of fertilizer screening, in particular to a biological fertilizer screening device. Background Art

[0002] Organic fertilizers, derived from plants and animals, are carbon-containing materials applied to the soil to provide nutrients for plants. Processed from biomass, animal and plant waste, and plant residues, they eliminate toxic and harmful substances and are enriched with beneficial substances. They not only provide comprehensive nutrition for crops, but also have a long-lasting effect, increasing and renewing soil organic matter.

[0003] The utility model patent with publication number CN220004798U in the prior art discloses a bio-organic fertilizer screening device. Through a screening cylinder and screening plates, bio-organic fertilizer can be screened into three different shapes: large, medium, and small. Organic fertilizers with smaller shapes fall out of the first discharge port, while organic fertilizers with medium and larger shapes flow out of the third and second discharge ports, respectively. However, because the receiving plate and the screening plate are both located within the screening housing, the screened fertilizer is discharged through the third and second discharge ports. After long-term use, fertilizer residue will remain on both the receiving plate and the screening plate. This not only makes it difficult to quickly screen and drop the fertilizer, but also makes it difficult to clean the tops of the receiving plate and the screening plate. To this end, we propose a bio-fertilizer screening device. Utility Model Content

[0020] The following will clearly and completely describe the technical solution of the present invention in conjunction with the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Reference Figures 1 to 3 The present invention provides a technical solution: a biofertilizer screening device, comprising a support platform 14 with a through slot 17 on the top, such as Figure 1 As shown, in order to facilitate the rapid falling of fertilizer, the top of the support platform 14 is tilted so that the fertilizer on its top can be quickly screened and fallen for collection, and two groups of brackets 10 are connected to the top of the support platform 14, and a material box 3 for placing fertilizer is provided between the two groups of brackets 10. At the same time, in order to prevent the fertilizer from falling, an extension portion 1 with an upward opening is connected to the top of the material box 3.

[0022] like Figure 2As shown, a first electric telescopic rod 7 is connected between the side wall of the material holding box 3 and each group of brackets 10, and a connecting plate 6 is fixedly connected to the side wall of the material holding box 3. A first electric telescopic rod 7 is connected between the connecting plate 6 and one of the brackets 10. Under the push of the first electric telescopic rod 7, the material holding box 3 can slide back and forth, thereby facilitating the rapid screening and processing of the fertilizer inside the material holding box 3, and under the push of the first electric telescopic rod 7, the material holding box 3 can be pushed toward the side of the support platform 14, thereby facilitating the discharge of the coarse-grained fertilizer after screening.

[0023] A first guide rod 4 is fixedly connected between the upper ends of each group of brackets 10. A first guide seat 5 is penetrated by the first guide rod 4 and is fastened to the side wall of the material box 3. A first spring 12 is fixedly connected between the side wall of the first guide seat 5 and the bracket 10, and the first spring 12 is coaxially arranged with the first guide rod 4. Under the elastic force of the first spring 12, the stability of the material box 3 during sliding can be improved. At the same time, for the stability of the entire device, a reinforcing rod 11 is fixedly connected between each group of brackets 10 when in use.

[0024] In order to achieve preliminary screening of fertilizer, a first frame 8 is rotatably connected to one side of the bottom of the material holding box 3, and a second screen 19 is connected inside the first frame 8. A second electric telescopic rod 26 is rotatably connected between one end of the first frame 8 and the side wall of the material holding box 3, and a mounting seat 25 is fixedly connected to the side wall of the material holding box 3. One end of the second electric telescopic rod 26 is rotatably connected to the top of the first frame 8, and the other end of the second electric telescopic rod 26 is rotatably connected to the mounting seat 25; an articulated seat 23 is fixedly connected to the side of the first frame 8 away from the second electric telescopic rod 26, and a connecting block 24 rotatably connected to the articulated seat 23 is provided on the side wall of the material holding box 3. When the fertilizer located on the top of the second screen 19 needs to be unloaded, the second electric telescopic rod 26 is controlled to push, and the first frame 8 rotates along the articulated seat 23. At this time, the first electric telescopic rod 7 controls the material holding box 3 to slide back and forth, which accelerates the rapid falling of the fertilizer. At the same time, the material holding box 3 is separated from the first frame 8, which is also convenient for cleaning the fertilizer residue on the top of the first frame 8.

[0025] like Figure 1 As shown, a first baffle 2 located in the material holding box 3 is fixedly connected to the top of the first frame 8, and the first baffle 2 is a U-shaped baffle. A second baffle 9 is symmetrically connected to the first frame 8 located outside the material holding box 3, and the second baffle 9 and the side wall of the first baffle 2 are in the same straight line. Under the action of the first baffle 2 and the second baffle 9, the screened fertilizer can be guided to ensure its rapid falling.

[0026] like Figure 2 、 3As shown, a second frame 15 is slidably connected to the top of the support platform 14, the second frame 15 is located above the through slot 17, and the first screen 13 is connected to the second frame 15. The first screen 13 is located directly below the second screen 19, and the mesh number of the first screen 13 is greater than the mesh number of the second screen 19. The fertilizer after screening by the second screen 19 falls on the top of the first screen 13, and the second screening can be achieved using the first screen 13.

[0027] In order to facilitate the rapid falling of the screened fertilizer, a third baffle 16 with a U-shaped structure is fixedly connected to the top of the second frame 15, one end of the third electric telescopic rod 27 is fixedly connected to the side wall of the third baffle 16 away from the opening, the third electric telescopic rod 27 is fastened to the top of the support platform 14, and the reciprocating motion of the third electric telescopic rod 27 can perform secondary screening of the fertilizer. The end of the third baffle 16 away from the opening is fixedly connected to a second guide rod 21 parallel to the third electric telescopic rod 27, and the top of the support platform 14 is fixedly connected to a second guide seat 22, the second guide rod 21 is arranged through the second guide seat 22, and a second spring 20 is connected between the second guide seat 22 and the third baffle 16, and the second spring 20 and the second guide rod 21 are coaxially arranged.

[0028] To sum up, when the biological fertilizer screening device is in use, a placement seat 18 is provided below the support platform 14, and a collection box for holding materials is placed on the top of the placement seat 18. The fertilizer to be screened is placed in the holding box 3, and the first electric telescopic rod 7 is controlled to drive the holding box 3 to move back and forth. The fertilizer with small particles falls to the top of the first screen 13, and the large particles remain on the top of the second screen 19. When the large-particle fertilizer with a large amount of accumulation needs to be collected, the second electric telescopic rod 26 is controlled to push one end of the first frame 8 to rotate downward, and the large-particle fertilizer can fall into the collection box. At the same time, it is also convenient for the staff to clean up the fertilizer residue on the top of the second screen 19.

[0029] After the small particles of fertilizer fall to the top of the first screen 13, the third electric telescopic rod 27 pushes the second frame 15 to move back and forth, thereby realizing secondary screening of the fertilizer. The screened fertilizer falls into the collection box directly below the through slot 17. The fertilizer located on the top of the first screen 13 can fall from the end of the second frame 15 and fall into the collection box below it. The utility model not only improves the efficiency of fertilizer screening, but also makes it convenient for the staff to quickly clean the tops of the first screen 13 and the second screen 19 to avoid clogging of the screen due to excessive residue.

[0030] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
