DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0023] As Figures 1 to 4As shown, a kind of organic fertilizer processing with screening structure crushing device, including the shell 1 of grinder, the top surface of shell 1 is provided with feed inlet 101, the shell 1 of grinder is provided with preliminary crushing assembly 2, preliminary crushing assembly 2 bottom is provided with the first discharge hopper plate 102, the first discharge hopper plate 102 below is provided with the secondary crushing blade 3 fixedly connected with preliminary crushing assembly 2, the second discharge hopper plate 103 is provided on the bottom of secondary crushing blade 3, and the second discharge hopper plate 103 is fixedly connected with multiple screening assembly 4 below.

[0024] As Figure 1 As shown in the utility model, the organic fertilizer processing with screening structure crushing device is similar to the structure of the existing organic fertilizer crushing device, and the patent with publication number CN218516815U discloses a kind of crushing device for organic fertilizer processing, and the main improvement point of the utility model is that the organic fertilizer raw material after crushing can be screened multiple times, as shown in Figures 1 to 4 As shown in the utility model, the organic fertilizer processing with screening structure crushing device is similar to the structure of the existing organic fertilizer crushing device, and the patent with publication number CN218516815U discloses a kind of crushing device for organic fertilizer processing, and the main improvement point of the utility model is that the organic fertilizer raw material after crushing can be screened multiple times, as shown in

[0025] As Figure 2As shown, the primary crushing assembly 2 includes two symmetrical rotating rods 201, which are provided with uniformly arranged crushing hammers 202. The crushing hammers 202 between the two rotating rods 201 are arranged in a staggered manner. The top surface of the crusher shell 1 is provided with a driving motor 203 for driving the rotating rods 201.

[0026] As shown, Figure 2 The bottom surface of the rotating rod 201 extends below the second discharging hopper plate 103. The secondary crushing blade 3 is a spiral blade, which is located between the first discharging hopper plate 102 and the second discharging hopper plate 103. The secondary crushing blades 3 between the two rotating rods 201 are arranged in a staggered manner.

[0027] Specifically, the two components are driven by the rotating rod 201 and the driving motor 203, reducing the transmission components, realizing continuous processing of coarse crushing and fine crushing of materials, significantly improving the crushing efficiency and product uniformity, and avoiding material accumulation by staggered arrangement of the crushing hammers 202, while also reducing mechanical resistance and prolonging the service life of the equipment. The secondary crushing blade 3 provides continuous shearing force in secondary crushing, thereby ensuring that the raw materials are finely crushed.

[0028] As shown, Figure 2 and Figure 3 The discharging opening of the second discharging hopper plate 103 is provided with an inclined rear guide plate 104.

[0029] Specifically, by arranging the inclined rear guide plate 104, the raw materials slide from the last end to the front end, thereby increasing the screening area and improving the screening efficiency.

[0030] As shown, Figure 3 and Figure 4 The multi-layer screening assembly 4 includes a screening shell 401 which has the same shape as the crusher shell 1. The top surface of the screening shell 401 is provided with a screening cavity 402. The front side of the screening shell 401 is provided with three sliding frames 403 which slide in the screening cavity 402. The inner walls of the sliding frames 403 are attached to the inner walls of the screening cavity 402. The placing rods 404 are arranged between the sliding frames 403 on the front and rear sides. The rear placing rod 404 is higher than the front placing rod 404. The inclined forward screening plates 405 are arranged between the placing rods 404. The excess material guide plates 406 are arranged on the front end of the front placing rod 404 of the sliding frame 403 and extend out of the screening shell 401. The push-pull plates 407 are arranged above the excess material guide plates 406 and are attached to the outer wall of the screening shell 401. The excess material conveying belts 409 are arranged on the bottom surface of the screening cavity 402 and extend through the front and rear sides.

[0031] Specifically, under the guidance of the inclined backward material guide plate 104, the crushed raw materials will fall to the rear end of the screening shell 401 and fall onto the screening plate 405 for primary screening. The first screening plate 405 will be inclined forward under the guidance of the placing rod 404, and the screened raw materials will slide out of the device from the excess material guide plate 406. These excess materials will be subjected to secondary crushing or used for other processing steps according to the precision of the selected screening plate 405 and production needs. Then, the screened raw materials will fall onto the second screening plate 405 and repeat the above screening process to achieve screening. Finally, the screened raw materials will be transported to the designated location on the excess material conveying belt 409, completing the crushing and screening separation of the raw materials.

[0032] As shown in Figures 1 to 3 , the three sliding frames 403 are symmetrically arranged front and back. The middle sliding frame 403 slides on the rear side of the screening shell 401, and the remaining two sliding frames 403 slide on the front side of the screening shell 401. The components carried by each sliding frame 403 are symmetrically arranged in the same direction as the sliding direction.

[0033] Specifically, by arranging the sliding frames 403 symmetrically front and back, the inclination direction of the screening is forward and backward, so that during the screening process, the raw materials do not slide in only one direction. The flow of raw materials will change direction three times: forward, backward, and forward, increasing the screening area and improving the screening efficiency.

[0034] As shown in Figure 4 , the vibration generator 408 is arranged inside the sliding frame 403.

[0035] Specifically, by arranging the vibration generator 408, the screen hole is prevented from being blocked. Combined with the excess material guide plate 406 and the push-pull plate 407, automatic grading and discharging can be achieved, reducing manual intervention. The vibration generator 408 is connected to the outside through a cable, which is convenient for the responsible personnel to connect the cable to the power supply, ensuring the smooth operation of the vibration generator 408.

[0036] As shown in Figures 1 to 3 , the screening shell 401 is provided with a rotatable fixing block 5 for fixing the push-pull plate 407.

[0037] Specifically, by arranging the rotatable fixing block 5 to fix the push-pull plate 407, the fixing and loosening of the push-pull plate 407 can be quickly realized, simplifying the fixing process and improving the flexibility of the device operation.

[0038] Although the utility model has been explained in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or make equivalent replacement to part of the technical features, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
