Description

Technical Field

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

[0002] Currently, the general process of organic fertilizer processing mainly includes raw material collection, pretreatment (such as drying and crushing), fermentation and composting, screening and grading, granulation and molding, drying and cooling, and packaging and storage. These steps ensure the effective utilization of raw materials and the high quality of organic fertilizer products. Among them, the screening and grading process can classify organic fertilizers according to particle size. The finely divided fertilizers can meet the fertilization needs of different crops, different growth stages, and different soil conditions. At the same time, screening can remove impurities and undecomposed organic matter in organic waste, improve the purity and quality of fertilizers, and make the fertilizers more uniform and fine, which is conducive to crop absorption and utilization.

[0003] Organic fertilizer screening equipment usually uses a drum screen; however, since organic fertilizer often contains fibers, large impurities and other substances that are easy to clog the screen holes, an anti-clogging brush is generally installed on one side of the drum screen. The anti-clogging brush can continuously clean the adhesions on the screen holes as the drum screen rotates, ensuring the smooth flow of the screen holes, thereby improving screening efficiency and product quality.

[0004] However, the existing anti-blocking brush is generally fixed, and the distance between it and the drum screen cannot be adjusted. During the screening process, as the bristles of the anti-blocking brush continue to wear, the distance between the bristles and the screen surface of the drum screen continues to increase, and the contact force between the two is also weakened, which is bound to affect the effect of cleaning the sieve holes; if the anti-blocking brush is discarded and replaced with an old one when it can still be used, it will not only increase the company's production costs, but also delay the production progress to a certain extent.

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0023] Example 1

[0025] Combine Figure 1As shown, a screening device for organic fertilizer processing includes a frame 1, a screen drum 2 is tiltedly arranged on the frame 1, a crossbeam 11 is arranged on the top of one side of the frame 1 along the axial direction of the screen drum 2, and suspension components 4 are respectively arranged at both ends of the crossbeam 11. An anti-blocking brush 3 is rotatably mounted between the two suspension components 4, and the length of the anti-blocking brush 3 is the same as the length of the screen surface of the screen drum 2; a driving component 5 for driving the two suspension components 4 to rotate synchronously is also provided on the crossbeam 11.

[0026] By adopting the above technical solution, the screening device rotates and installs the anti-blocking brush 3 by arranging two suspension components 4 on the crossbeam 11, so that the anti-blocking brush 3 can continuously and dynamically clean the sieve holes as the sieve drum 2 rotates; at the same time, the driving component 5 arranged on the crossbeam 11 can drive the two suspension components 4 to rotate synchronously, so as to adjust the distance and contact force between the bristles of the anti-blocking brush 3 and the screen surface of the sieve drum 2; when the bristles of the anti-blocking brush 3 increase the distance from the screen surface due to wear and the cleaning effect weakens, the distance can be conveniently adjusted to restore or optimize the cleaning effect, and there is no need to frequently replace the anti-blocking brush 3, thereby extending the service life of the anti-blocking brush 3 and reducing production costs.

[0027] Preferably, annular grooves 21 are fixedly sleeved at both ends of the screen drum 2, the bottom of the annular groove 21 is rotatably engaged with two support wheels 12 arranged on the frame 1, and its two side portions are rotatably engaged with guide wheels 13 symmetrically arranged on the frame 1.

[0028] By adopting the above technical solution, the annular groove 21, the support wheel 12 and the guide wheel 13 cooperate to form a shaftless rotating structure that supports and rotates the screen drum 2, so that the organic fertilizer in the screen drum 2 can be better and more comprehensively screened and graded, thereby improving the screening efficiency.

[0029] Preferably, a ring rack 22 is fixedly sleeved on the upper end of the screen drum 2, and the ring rack 22 is used for transmission engagement connection with the power output end of the external motor.

[0030] By adopting the above technical solution, the provided ring rack 22 can be connected in a transmission meshing manner with the power output end of an external motor (not shown in the figure), so that the rotation of the screen drum 2 can be driven in conjunction with the above shaftless rotation structure.

[0031] Preferably, the feed port of the screen drum 2 is connected to a feed hopper 6 with a conical structure.

[0032] By adopting the above technical solution, the conical feed hopper 6 can facilitate the smooth entry of organic fertilizer into the rotating screen drum 2, thereby improving the screening efficiency.

[0033] Preferably, a receiving tray 7 adapted thereto is provided directly below the screen drum 2 .

[0034] By adopting the above technical solution, the provided receiving tray 7 can centrally collect the undersize material of the screen drum 2, which is convenient for later transportation.

[0035] Example 2

[0036] like Figures 1 to 3 As shown, based on the above embodiment, this embodiment further provides the following content:

[0037] In order to adjust the distance between the anti-blocking brush and the screen drum, the following solution is given:

[0038] In this embodiment, if Figure 1 and Figure 2 As shown, the suspension assembly 4 includes a cantilever 41 and a support seat 42. The support seat 42 is vertically fixed to the top surface of the beam 11. One end of the cantilever 41 is detachably rotatably connected to the end corresponding to the anti-blocking brush 3, and the other end is rotatably connected to the support seat 42.

[0039] By adopting the above technical solution, the suspension assembly 4 is composed of a cantilever 41 and a support seat 42. One end of the cantilever 41 is detachably connected to the anti-blocking brush 3, and the other end is rotatably connected to the support seat 42. This design allows for better flexibility in adjusting the distance between the anti-blocking brush 3 and the screen surface of the screen drum 2 according to the wear of the anti-blocking brush 3 during the screening process, ensuring that appropriate contact force is always maintained between the two.

[0040] like Figure 2 and Figure 3 As shown, the driving assembly 5 includes a rotating shaft 51, and the two ends of the rotating shaft 51 are respectively rotatably connected with the corresponding support seat 42, and the cantilever 41 is vertically fixed to the end face of the corresponding rotating shaft 51; a gear 52 is axially fixedly sleeved on the middle part of the rotating shaft 51, and the outer side of the gear 52 is longitudinally meshed and connected with an L-shaped tooth plate 53, and the two side surfaces of the vertical part of the tooth plate 53 are respectively vertically and symmetrically fixed with ridges 531, and the ridges 531 are longitudinally slidably engaged with the limiting grooves 54 vertically connected to the side surfaces of the corresponding beams 11; the bottom surface of the beam 11 is vertically connected with an L-shaped plate 55, and the horizontal part of the L-shaped plate 55 is vertically rotatably connected with a threaded rod 56, and the threaded rod 56 is transmission screwed to the horizontal part of the tooth plate 53.

[0041] By adopting the above technical solution, the driving assembly 5 is set to drive the tooth plate 53 to slide longitudinally in the limit groove 54 by rotating the threaded rod 56. Since the tooth plate 53 is engaged with the gear 52, the movement of the tooth plate 53 will drive the gear 52 and the rotating shaft 51 to rotate, thereby changing the position of the cantilever 41 and the anti-blocking brush 3, thereby realizing the adjustment of the screen surface distance between the anti-blocking brush 3 and the screen drum 2, maintaining the contact force between the two, and ensuring that the sieve hole cleaning effect is not affected. When the anti-blocking brush 3 can still be used, there is no need to discard the old one and update it, thereby reducing the company's production costs and delays in production progress.

[0042] like Figure 3 As shown, a spring 58 is axially sleeved on the threaded rod 56 , one end of the spring 58 is connected to the bottom surface of the horizontal portion of the tooth plate 53 , and the other end is connected to the top surface of the horizontal portion of the L-shaped plate 55 .

[0043] By adopting the above technical solution, the spring 58 provided can enable the tooth plate 53 to absorb and buffer these forces through the elastic deformation of the spring 58 when it is subjected to the push or pull from the threaded rod 56, thereby playing a buffering and shock-absorbing effect, reducing the impact and vibration caused by mechanical transmission, and protecting the structures of the driving component 5 and the suspension component 4 from damage.

[0044] like Figure 3 As shown, a turning handle 57 is vertically fixed to the bottom end of the threaded rod 56 .

[0045] By adopting the above technical solution, the provided turning handle 57 is convenient for manual grasping and rotating the threaded rod 56 .

[0046] like Figure 2 As shown, bearing seats 511 are respectively connected to the rotating shaft 51 on both sides of the gear 52 so as to rotate axially symmetrically, and the bearing seats 511 are vertically connected to the top surface of the beam 11.

[0047] By adopting the above technical solution, the two bearing seats 511 are set up so that the rotating shaft 51 is better supported and positioned during the rotation process; the bearing seat 511 serves as the connection point between the rotating shaft 51 and the beam 11, which can effectively reduce the shaking and deviation of the rotating shaft 51 during the rotation process, thereby enhancing the stability of the rotating shaft 51.

[0048] The working principle and use process of this utility model:

[0049] When the utility model is in use, first, the screening device is started, the screen drum 2 starts to rotate, and then the organic fertilizer is continuously fed into the screen drum 2 through the feed hopper 6. As the screen drum 2 rotates, the anti-blocking brush 3 contacts the screen drum 2 and rotates synchronously. The bristles of the anti-blocking brush 3 contact the screen surface of the screen drum 2, continuously cleaning the adhesion on the screen holes to ensure the smooth flow of the screen holes.

[0050] If the bristles of the anti-blocking brush 3 are worn, causing the distance between the anti-blocking brush 3 and the screen surface of the sieve drum 2 to increase, affecting the cleaning effect, the position of the anti-blocking brush 3 can be changed by adjusting the threaded rod 56. That is, rotating the handle 57 drives the threaded rod 56 to move up and down, thereby pushing the tooth plate 53 to slide along the limit groove 54. Since the tooth plate 53 is engaged with the gear 52, the gear 52 rotates accordingly, driving the rotating shaft 51 and the cantilever 41 to rotate, thereby adjusting the distance between the anti-blocking brush 3 and the screen surface of the sieve drum 2. After adjustment, the anti-blocking brush 3 continues to effectively clean the sieve holes, ensuring screening efficiency and product quality; the entire screening process continues until the screening task of the organic fertilizer is completed.

[0051] 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 and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
