Abstract
Description
Technical Field
[0001] This utility model relates to the field of wettable powder conveying technology, and in particular to a vibrating screen conveying assembly for preventing caking of wettable powders. Background Technology
[0002] Wettable powder is a formulation made by thoroughly mixing and pulverizing pesticide technical, inert filler and a certain amount of adjuvants in a certain proportion to achieve a certain particle fineness. In terms of appearance, it is no different from powder. However, due to the addition of wetting agents and dispersants, it can be wetted and dispersed by water after being added to form a suspension, which can be sprayed.
[0003] A search revealed Chinese Patent Publication No. CN221661076U, which discloses a bending device for processing automotive parts and a conveying device for packaging wettable powder pesticides. The device includes a conveying mechanism for conveying wettable powder pesticides. Its key feature is that several spaced-apart feeding mechanisms are installed along the length of the conveying mechanism. This technical solution uses these feeding mechanisms to agitate the wettable powder pesticide to prevent further shearing. However, this structure lacks a sieving structure, and wettable powders are prone to absorbing moisture and clumping. In actual use, clumping often leads to poor conveying and localized blockages, affecting conveying efficiency and potentially causing measurement errors in subsequent packaging stages. The overall performance is insufficient to meet production needs. Therefore, a vibrating sieving and conveying assembly for preventing clumping of wettable powders is proposed to address these problems. Utility Model Content

[0006] A vibrating sieve conveying assembly for preventing caking of wettable powder includes a conveyor frame, on the inner side of which a conveyor belt is provided for conveying wettable powder.
[0007] The outer side of the conveyor frame is provided with a material guiding assembly extending above it for receiving and guiding the wettable powder.
[0008] The inner side of the feeding assembly is provided with a screening mechanism extending to its right side; used for screening wettable powders.

[0013] Preferably, the crushing mechanism includes a connecting hopper, which is fixedly installed on the right side of the guide hopper and located outside the screening plate. Inside the connecting hopper, two crushing rollers are rotatably installed via a rotating shaft and located below the screening plate.

The bottom of the connecting hopper is designed with an inclined structure.
[0016] Compared with the prior art, the beneficial effects of this utility model are:
[0017] This wettable powder anti-caking vibrating screening and conveying assembly, through the coordinated design of the material guiding component and the screening mechanism, uses a vibrating motor to generate vibration of the screening plate and an elastic support (support spring) to create an inclined structure. This not only efficiently loosens agglomerated materials and promotes fine powder screening, but also avoids rigid collisions that can generate new agglomerates.
[0018] This wettable powder anti-caking vibrating screening and conveying assembly features a combined crushing and return mechanism. The crushing mechanism's dual-roller synchronous crushing design provides secondary processing for large particles remaining after screening, ensuring uniform particle size. The return mechanism's screw conveyor and feeding pipe combination enables precise return of crushed material, preventing blockages or splashing, forming a continuous circulating screening process. This significantly improves anti-caking efficiency, reduces material waste, and substantially enhances the continuity and reliability of the production process. Attached Figure Description

[0029] Example
[0030] like Figure 1-5 As shown, this utility model provides a technical solution: a vibrating sieve conveying assembly for preventing caking of wettable powder, including: a conveyor frame 1, and a conveyor belt 2 arranged on the inner side of the conveyor frame 1 for conveying wettable powder. The conveyor frame 1 serves as the basic support frame of the entire assembly, and the conveyor belt 2 undertakes the task of conveying the wettable powder.
[0031] A material guiding assembly 3 extending above the outer side of the conveyor frame 1 is provided for receiving and guiding the wettable powder. The material guiding assembly 3 includes a connecting frame 31. There are two connecting frames 31, which are fixedly installed on the front and rear sides of the conveyor frame 1 respectively. A material guiding hopper 32 located above the conveyor belt 2 is fixedly installed between the two connecting frames 31. The material guiding hopper 32 is stably suspended above the conveyor frame 1 by the two connecting frames 31, serving as a "guide channel" for the material.
[0032] The inner side of the feeding assembly 3 is provided with a screening mechanism 4 extending to its right side; it is used to screen wettable powders. The screening mechanism 4 includes a screening plate 41, which is movably installed inside the feeding hopper 32 and extends to its right side. The screening plate 41 has an inclined structure design. Two support blocks 42 are fixedly installed on both the left and right sides of the inner wall of the feeding hopper 32 and located below the screening plate 41. A vibration motor 43 is fixedly installed at the bottom of the screening plate 41. A movably installed support block 42 extends to its top and is connected to the screening plate 41. The plate 41 is fixedly connected to the support rod 44, and the bottom of the support rod 44 is fixedly connected to the support plate 45 located inside the support block 42. The bottom of the support plate 45 is fixedly installed with the support spring 46. This wettable powder anti-caking vibrating screening and conveying assembly, through the coordinated design of the material guiding assembly 3 and the screening mechanism 4, the screening plate 41 generates vibration through the vibration motor 43 and cooperates with the elastic support (support spring 46) in an inclined structure, which can not only efficiently loosen the agglomerated material and promote the screening of fine powder, but also avoid rigid collisions that will generate new agglomerates.
[0033] A crushing mechanism 5 is provided on the right side of the feeding assembly 3; it is used to crush larger wettable powders after screening. The crushing mechanism 5 includes a connecting hopper 51, which is fixedly installed on the right side of the feeding hopper 32 and located outside the screening plate 41. Both the feeding hopper 32 and the inner wall of the connecting hopper 51 have through holes 411 adapted to the moving trajectory of the screening plate 41. The bottom of the connecting hopper 51 has an inclined structure design. Inside the connecting hopper 51, two crushing rollers 52 are rotatably mounted via a rotating shaft and located below the screening plate 41. A drive motor 53 is fixedly installed on the front side of the connecting hopper 51. The output shaft of the drive motor 53 is fixedly connected to the rotating shaft of the crushing roller 52. A protective frame 54 is fixedly installed on the rear side of the connecting hopper 51. The rotating shaft of the crushing roller 52 extends into the interior of the protective frame 54 and is fixedly connected to a gear 55. The two gears 55 mesh with each other. A discharge pipe 56 communicating with the interior of the connecting hopper 51 is fixedly connected to the bottom of the connecting hopper 51. The connecting hopper 51 receives large particles of material after screening and crushes them into fine powder through the squeezing and shearing action of the roller body to ensure uniform particle size of the material.
[0034] A return material mechanism 6 is provided on the rear side of the crushing mechanism 5, communicating with it and extending above the material guiding assembly 3. This mechanism is used to convey and re-screen the crushed wettable powder. The return material mechanism 6 includes a mounting plate 61, which is fixedly installed on the top of the connecting hopper 51. A conveying cylinder 62, extending through to its bottom and communicating with the discharge pipe 56, is fixedly installed on the top of the mounting plate 61, serving as a "closed conveying channel" to prevent dust from being generated during the conveying process. A spiral conveying auger 63, controlled by a motor, is fixedly installed on the top of the conveying cylinder 62. The outer side of the conveying cylinder 62 is fixedly... The wettable powder anti-caking vibrating screening and conveying assembly is equipped with a feeding pipe 64 that communicates with its interior and extends into the guide hopper 32 at one end. Through the coordinated design of the crushing mechanism 5 and the return mechanism, the double-roller synchronous crushing design in the crushing mechanism 5 performs secondary processing on the large particles remaining after screening to ensure uniform particle size. The spiral conveying auger 63 of the return mechanism 6 is combined with the feeding pipe 64 to achieve precise return of the crushed material, prevent blockage or splashing, form a continuous circulating screening process, greatly improve the anti-caking processing efficiency, reduce material waste, and significantly improve the continuity and reliability of the production process.
[0035] The working process of this utility model:
[0036] Step 1: The wettable powder is guided by the feed hopper 32 to fall onto the screening plate 41 of the inclined screening mechanism 4. The screening plate 41 vibrates continuously under the drive of the bottom vibration motor 43. At the same time, the vibration effect is enhanced by the elastic buffering of the support rod 44, support plate 45 and support spring 46 in the support blocks 42 on both sides, so that the agglomerates or larger particles are loosened and screened due to vibration.
[0037] Step 2: The wettable powder material that passes the screening is guided by the guide hopper 32 to fall onto the conveyor belt 2 for forward conveying. Large particles that fail to pass through the screen holes move to the right along the inclined trajectory of the screening plate 41 and finally fall into the crushing mechanism 5 in the connecting hopper 51. The drive motor 53 on the front side of the connecting hopper 51 drives two crushing rollers 52 that rotate in opposite directions through the rotating shaft (the two roller shafts are meshed synchronously through gears 55) to crush large particles or agglomerated materials.
[0038] Step 3: The crushed material falls into the conveying cylinder 62 of the return material mechanism 6 through the discharge pipe 56 of the connecting hopper 51 (with an inclined bottom design). It is then pushed to the feeding pipe 64 by the spiral conveying auger 63 (controlled by a motor) inside the conveying cylinder 62, and then sent back to the guide hopper 32 to participate in the next round of screening until the material has completely passed through the screening and is then conveyed by the conveyor belt 2.
[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
