Description

Technical Field

[0001] This utility model relates to the technical field of organic fertilizer processing, and in particular to an organic fertilizer screening device. Background Technology

[0002] Organic fertilizer, also known as "farmyard manure," refers to any fertilizer made from organic matter, including human excrement, manure, compost, green manure, oilseed cake, and biogas slurry. To grade, purify, and screen organic raw materials, ensuring the quality, applicability, and production efficiency of organic fertilizer, organic fertilizer screening devices are frequently used during processing to remove impurities and control particle size.

[0003] When using organic fertilizer screening equipment for raw material screening, if the organic fertilizer raw material has high moisture content, strong viscosity, or the particle size of the raw material is close to the diameter of the filter screen mesh, it is very easy for the raw material to clog the screen mesh. This clogging problem will directly interfere with the normal operation of the screening equipment. Currently, when clogging occurs, workers usually try to deal with it by tapping the roller, attempting to use external force to vibrate the roller and dislodge the blockage in the screen mesh. However, this method has two drawbacks. First, frequent manual tapping significantly increases the labor intensity of workers and affects the overall operation progress. Second, long-term or improper tapping may cause hidden damage to the roller structure, shorten the service life of the equipment, and increase later maintenance costs. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the above-mentioned technologies.

[0005] Therefore, one objective of this utility model is to provide an organic fertilizer screening device that utilizes the shaking of the screening device itself during operation to amplify it, thereby shaking out raw materials that are clogging the screen mesh and thus achieving the effect of preventing clogging.

[0006] To achieve the above objectives, the first aspect of this utility model provides an organic fertilizer screening device, comprising: a screening machine and an anti-blocking mechanism, wherein the anti-blocking mechanism includes a connecting plate, multiple limiting posts, a bottom plate and multiple springs, wherein the connecting plate is disposed on the bottom wall of the screening machine; the multiple limiting posts are respectively disposed on the bottom wall of the connecting plate, and the bottom plate is connected to the other end of the multiple limiting posts; the multiple springs are respectively sleeved on the outside of the corresponding limiting posts, and the two ends of the multiple springs are respectively connected to the connecting plate and the bottom plate.

[0007] In addition, the organic fertilizer screening device proposed above according to this utility model may also have the following additional technical features: Specifically, the screening machine includes a frame, a discharge bin, two support frames, a drum, a drive unit, and a conveying hopper. The discharge bin is mounted on the frame; the two support frames are mounted on the discharge bin; the drum is pivotally connected to the two support frames; the drive unit's shaft is connected to one end of the drum, and the conveying hopper is mounted at the other end of the drum.

[0008] Specifically, a door is slidably connected to the outer wall of the roller.

[0009] Specifically, a baffle is installed on the frame.

[0010] Specifically, ear plates are provided on both sides of the base plate.

[0011] Specifically, rubber pads are evenly spaced on the bottom wall of the base plate.

[0012] Compared with existing technologies, this invention has the following advantages: During the operation of the screening device, the equipment itself will naturally vibrate due to mechanical operation. The vibration energy can be enhanced by adding an elastic vibration component below the device. When the screen receives enhanced, regular vibration, the clogging material stuck in the screen holes will be subjected to continuous high-frequency impact and centrifugal force, effectively dispersing particles that were originally compressed or adhered stickily. This anti-clogging method, which utilizes the equipment's own power conversion, eliminates the need for additional large drive devices. It can accurately remove retained materials from the screen holes and reduce downtime losses caused by manual cleaning, thus ensuring screening efficiency while achieving a continuous and stable anti-clogging effect.

[0013] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0016] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0017] The organic fertilizer screening device of this utility model is described below with reference to the accompanying drawings.

[0018] like Figures 1-4 As shown, the organic fertilizer screening device of this utility model embodiment includes: a screening machine 1 and an anti-blocking mechanism 4.

[0019] The anti-blocking mechanism 4 includes a connecting plate 41, multiple limit posts 42, a base plate 43, and multiple springs 44.

[0020] The connecting plate 41 is set on the bottom wall of the screening machine 1, and multiple limiting posts 42 are respectively set on the bottom wall of the connecting plate 41. The bottom plate 43 is connected to the other end of the multiple limiting posts 42. Multiple springs 44 are respectively sleeved on the outside of the corresponding limiting posts 42, and the two ends of the multiple springs 44 are respectively connected to the connecting plate 41 and the bottom plate 43.

[0021] It should be noted that in the technical solution of this embodiment, the spring 44 remains in a naturally straight and undeformed state in the initial state before being subjected to the force of the jitter. This structural design allows the spring 44 to undergo significant deformation due to its own elastic properties when subjected to external jitter interference, thereby effectively amplifying the original jitter amplitude through the conversion and release of elastic potential energy.

[0022] The screening machine 1 includes a frame 11, a discharge bin 12, two support frames 13, a drum 14, a drive unit 15, and a conveying hopper 16.

[0023] It should be noted that the driving component 15 described in this embodiment is a drive motor.

[0024] The discharge bin 12 is mounted on the frame 11, and two support frames 13 are mounted on the discharge bin 12 respectively. The roller 14 is pivotally connected to the two support frames 13. The shaft of the drive component 15 is connected to one end of the roller 14, and the conveying hopper 16 is mounted on the other end of the roller 14.

[0025] Specifically, when it is necessary to screen organic fertilizer raw materials, the staff can transport the raw materials through the conveying hopper 16 into the inside of the drum 14, and then use the control device to start the drive component 15. At this time, the drive component 15 will drive the drum 14 to rotate inside the two support frames 13. At this time, the raw materials that meet the size requirements of the drum 14 will enter the discharge hopper 12 through the drum 14 and then be discharged through the discharge hopper 12.

[0026] During the rotation of the roller 14 driven by the drive component 15, the vibration generated by the rotation of the roller 14 is transmitted to the spring 44 through the connecting plate 41. At this time, the spring 44 will repeatedly compress and rebound along the direction limited by the limit post 42, thereby amplifying the vibration generated by the rotation of the roller 14. When the roller 14 obtains enhanced regular vibration, the raw material stuck in the screen hole is subjected to continuous high-frequency impact force and centrifugal force, which will effectively disperse the particles that were originally squeezed or adhered stickily, thereby achieving the effect of preventing blockage.

[0027] In one embodiment of this utility model, such as Figures 1-2 As shown, the outer wall of the roller 14 is slidably connected to the door 2.

[0028] It is understandable that, after screening, the workers can slide the door 2, which is slidably connected to the outer wall of the drum 14, to open it and discharge the material inside the drum 14.

[0029] In one embodiment of this utility model, such as Figure 1 and Figure 3 As shown, a flow guide plate 3 is installed on the frame 11.

[0030] Understandably, the guide plate 3 installed on the frame 11 can be used to guide the screened particles through the guide plate 3 during the screening process, thereby discharging them together for easy collection.

[0031] In one embodiment of this utility model, such as Figure 1 and Figure 4 As shown, ear plates 5 are respectively provided on the two side walls of the base plate 43.

[0032] Understandably, with the ear plates 5 set on both sides of the base plate 43, workers can use expansion bolts to connect the screening machine 1 to the ground, thereby fixing the screening machine 1 to the ground.

[0033] In one embodiment of this utility model, such as Figure 4 As shown, rubber pads 6 are equidistantly arranged at the bottom of the base plate 43.

[0034] Understandably, the rubber pads 6 evenly spaced on the bottom wall of the base plate 43 increase the friction between the screening machine 1 and the ground, thereby improving the stability of the screening machine 1.

[0035] In summary, during the operation of the screening device, the equipment itself will naturally vibrate due to mechanical operation. This vibration energy can be enhanced by installing an elastic vibration component below the device. When the screen receives this enhanced, regular vibration, the clogging material stuck in the screen openings will be subjected to continuous high-frequency impact and centrifugal force, effectively dispersing particles that were originally compressed or adhered stickily. This anti-clogging method, utilizing the equipment's own power conversion, eliminates the need for additional large drive devices. It can accurately remove residual material from the screen openings while reducing downtime losses caused by manual cleaning, thus ensuring screening efficiency while achieving a continuous and stable anti-clogging effect.
