Description

Technical Field

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

[0002] Fertilizers are substances that provide one or more essential plant nutrients, improve soil properties, and increase soil fertility. They are one of the material foundations of agricultural production. They primarily include ammonium phosphate fertilizers, water-soluble macronutrient fertilizers, secondary element fertilizers, biofertilizers, organic fertilizers, and multi-dimensional field energy concentrated organic fertilizers.

[0003] During the fertilizer processing and production process, it is necessary to screen particles of different sizes. Unqualified fertilizer particles are screened out and discharged from the discharge port into the mixer for re-mixing and granulation. However, the existing screening device can only perform reciprocating screening during the fertilizer screening process. Although this can achieve the screening of fertilizers, it cannot handle blocked fertilizers during the screening process. At the same time, the accumulation of large amounts of fertilizers will also affect the final screening effect of the fertilizers.

[0004] To this end, we proposed a fertilizer screening device to solve the problem Utility Model Content

Specific implementation manners

[0030] For a clearer understanding of the technical features, purposes and effects of the present utility model, the specific implementation manners of the present utility model are now described in conjunction with the attached drawings.

[0031] Embodiment 1

[0032] A preferred embodiment of a fertilizer screening device provided by the present utility model is as Figures 1 to 4 shown: A fertilizer screening device includes:

[0033] Mounting frame 1, a support 2 is fixedly installed at the bottom of the mounting frame 1, the number of supports 2 is four, the four supports 2 are respectively distributed at the bottom corners of the mounting frame 1, and feet are fixedly installed at the bottom of the four supports 2, and the entire device can be firmly supported by the supports 2 installed at the bottom corners of the mounting frame 1;

[0034] Cross plates 7, the number is two, and the cross plates 7 are fixedly installed at the top of the front end position of the mounting frame 1, a frame plate 3 is fixedly installed at the top of the cross plate 7, and a feed plate 4 is fixedly installed at the right end of the frame plate 3. The frame plate 3 installed can prevent the flipping component 8 from flipping the fertilizer out during the flipping process, and the feed plate 4 installed facilitates the entry of the fertilizer;

[0035] Screening component 5, disposed between the mounting frame 1 and the cross plate 1;

[0036] Flipping component 8, disposed above the screening component 5.

[0037] The screening component 5 includes:

[0038] The air cylinder 51 is arranged on the right side of the mounting frame 1, and a rubber column 52 is fixedly installed at one end of the air cylinder 51;

[0039] The sieve frame 53 is arranged between the two cross plates 7, and the right side surface of the sieve frame 53 is fixedly installed with the left end of the rubber column 52;

[0040] One end of the connecting column 56 is fixedly installed on one side of the sieve frame 53, and the connecting column 56 is slidably arranged in the track 54 opened on the surface of the cross plate 7. A limiting block 55 is fixedly installed at the end of the connecting column 56 away from the sieve frame 53.

[0041] In the specific process, by starting the air cylinder 51 to move the rubber column 52, the sieve frame 53 can be driven to move under the movement of the rubber column 52, and then reciprocating movement can realize the screening work of the sieve frame 53 on the fertilizer.

[0042] In this embodiment, the right end of the rubber column 52 is hollowed out, and the surface at this position has an opening. This setting can make the rubber column 52 droop downward easily when it is suspended downward.

[0043] Furthermore, the bottom of the inner wall of the track 54 has a wavy setting. In this way, with the cooperation of the rubber column 52, the connecting column 56 can have an up-and-down undulating movement during the movement process. In this way, the sieve frame 53 can have an up-and-down vibration during the screening process, which can shake the fertilizer open, facilitate screening, and at the same time avoid the blockage of the sieve frame 53.

[0044] Embodiment 2

[0045] On the basis of the above implementation scheme, the turning-over component 8 includes:

[0046] The rack 81 is fixedly installed on the top of the sieve frame 53, and the rack 81 is meshed with the gear 82;

[0047] The outer wall of the mounting shaft 83 is fixedly installed with the inner wall of the gear 82, and both ends of the mounting shaft 83 are rotationally connected to the inner wall of the frame plate 3 through bearings. A turning-over leaf 84 is fixedly installed on the outer wall of the mounting shaft 83.

[0048] In the specific process, through the arranged rack 81, it can move together with the sieve frame 53, and then the gear 82 can be rotated. Under the rotation of the gear 82, the mounting shaft 83 can drive the turning-over leaf 84 to rotate. Under the rotation of the turning-over leaf 84, the fertilizer can be turned over, making the screening more uniform. Here, the meshing of the gear 82 and the rack 81 will not be completely disengaged due to the up-and-down movement of the sieve frame 53.

[0049] Working principle: The fertilizer enters into the sieve frame 53 through the feeding plate 4, and then the air cylinder 51 is used to drive the rubber column 52 to move. At this time, the sieve frame 53 can move together with the rubber column 52. At this time, the connecting column 56 will move in the track 54. Due to the wavy setting at the bottom of the inner wall of the track 54, the hollowing and opening at one end of the rubber column 52 close to the air cylinder 51, the up-and-down undulation of the sieve frame 53 can be realized more smoothly. In this way, during the reciprocation of the air cylinder 51, the sieve frame 53 has an up-and-down vibration effect during the reciprocating screening process, which can shake off the fertilizer, facilitate screening, and at the same time avoid the blockage of the sieve frame 53, affecting the later screening effect. During the movement of the sieve frame 53, the rack 81 will have the same movement tendency. During the movement of the rack 81, the gear 82 can be rotated. Under the rotation of the gear 82, the mounting shaft 83 can be rotated. Through the rotation of the mounting shaft 83, the turning leaf 84 can be rotated. Under the rotation of the turning leaf 84, the fertilizer in the sieve frame 53 can be turned over, which is convenient for screening the fertilizer.

[0050] The above is only a schematic specific embodiment of the present invention and is not intended to limit the scope of the present invention. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principle of the present invention shall fall within the scope of protection of the present invention. Moreover, it should be noted that the components of the present invention are not limited to the above overall application. Each technical feature described in the specification of the present invention can be selected and used alone according to actual needs or multiple features can be combined for use. Therefore, the present invention should naturally cover other combinations and specific applications related to the inventive points of this case.
