Description

Technical Field

[0001] This utility model relates to the field of material sorting, and in particular to a material dispersing device. Background Technology

[0002] In the field of material sorting, especially for materials that are inherently sticky and prone to clumping, such as citrus segments and other secondary processed fruits, traditional production lines generally use conveyor belts for material transport. However, after being fed into the front-end feeding device, these materials, due to their sticky nature, often accumulate in the middle area of ​​the conveyor belt, forming tightly bound lumps. This aggregation prevents the material from spreading evenly during transport, leading to two main problems: first, lumps are easily misjudged as a single unit by the system in subsequent sorting processes, resulting in omissions or incorrect processing; second, defective products or impurities encased within the lumps are difficult to effectively identify and separate, significantly reducing the final sorting accuracy and product quality. Current technologies lack dedicated processing mechanisms for sticky materials. The entire process from material input to entry into the sorting stage relies on natural flow and gravity dispersion, which is unsuitable for highly sticky and easily clumped materials. Especially when handling different types or materials with varying physical states, fixed-structure conveyor equipment cannot dynamically adjust its dispersion strategy, resulting in fluctuating sorting efficiency and insufficient stability. Furthermore, existing equipment is difficult to adapt quickly and flexibly to changes in production line speed or material characteristics, further limiting the optimization space for sorting effect.

[0003] In summary, existing material sorting production lines, due to inherent defects in the conveying process, struggle to address the uneven distribution caused by the agglomeration of viscous materials, thus affecting sorting accuracy and production efficiency. Therefore, how to specifically improve the uniformity of dispersion during the conveying of viscous materials is a technical problem that needs to be solved. Utility Model Content

[0004] The purpose of this invention is to overcome the defects of the existing technology and provide a material dispersing device that disperses materials by means of a diversion rake, and adapts to different material dispersing and screening conditions with different sizes and requirements by adjusting the diversion rake spacing, rake tooth spacing and diversion rake suspension height.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] According to one aspect of the present invention, a material dispersing device is provided, including a conveyor belt, a dispersing drive device, a diverting rake assembly mounting limit frame and a diverting rake, wherein the diverting rake is suspended above the conveyor belt by the diverting rake assembly mounting limit frame, and the dispersing drive device is electrically connected to the diverting rake.

[0007] The dispersing drive device includes a motor, a motor mounting plate, a speed controller, and a power supply; the diverting rake includes a bearing housing, a coupling, a transmission shaft, and rake teeth. A square tube sleeve is fixed on the transmission shaft, and the rake teeth are welded to the square tube sleeve. Bearing housings are respectively located at both ends of the transmission shaft. The coupling is located on the motor side, connecting the bearing housings to the motor; the diverting rake assembly mounting limit frame is fixed on the conveyor belt mounting platform on both sides of the conveyor belt, and a diverting rake assembly mounting adjustment plate is fixed at the upper end.

[0008] Furthermore, the square tube sleeve is a cuboid with four sides, and rake teeth are evenly distributed on each side, the spacing of which is selected according to the material being selected.

[0009] Furthermore, the rake teeth on any side of the square tube sleeve are fixedly offset from the rake teeth on the adjacent side, and the rake teeth on opposite sides are on the same straight line.

[0010] Furthermore, the rake teeth are cylindrical metal strips.

[0011] Furthermore, the rake teeth are square metal strips.

[0012] Furthermore, the rotation direction of the diverting rake is opposite to the running direction of the conveyor belt.

[0013] Furthermore, the bearing housing is connected to the diversion rake assembly mounting adjustment plate via threaded holes and screws, and the diversion rake assembly mounting adjustment plate is provided with multiple sets of threaded holes of different heights.

[0014] Furthermore, the height difference between the diverting rake and the conveyor belt is continuously adjusted by mounting an adjustment plate on the diverting rake assembly.

[0015] Furthermore, multiple diversion rakes are installed on the conveyor belt.

[0016] Furthermore, multiple sets of mounting holes are provided on both sides of the conveyor belt installation platform for installing the diversion rake assembly mounting limit frame, so as to adjust the spacing of each diversion rake.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] (1) Adapt to the dispersing requirements of different materials: Through the design of adjustable spacing rake teeth on the square tube sleeve, combined with the staggered distribution structure of rake teeth on adjacent sides, the dispersing density and intensity can be flexibly adjusted for materials with different viscosity and size. Operators can adjust the spacing of rake teeth according to the characteristics of the material to avoid large pieces of material from being blocked due to excessively dense rake teeth, or small particles of material from being insufficiently dispersed due to excessively sparse rake teeth.

[0019] (2) Achieve multi-dimensional precise adjustment: By using the multiple sets of height threaded holes on the adjustment plate of the diversion rake assembly and the multiple sets of mounting holes on both sides of the conveyor belt mounting platform, the longitudinal height, horizontal position and spacing of the diversion rakes can be adjusted independently. This design enables the device to quickly adapt to production line conveyor belts of different speeds and adjust the dispersing depth in real time according to the material accumulation thickness to ensure that the material layer passes through the diversion rake area evenly.

[0020] (3) Improve the efficiency and reliability of dispersing: The diverting rake adopts a rotation design opposite to the direction of the conveyor belt, which enhances the shearing force on the sticky material through reverse impact; at the same time, the welded structure of the square tube sleeve and the rake teeth avoids the risk of loosening and falling off of the traditional assembled rake teeth. In continuous production scenarios, this structure can stably maintain a high-speed rotation state and reduce the frequency of equipment downtime maintenance. Attached Figure Description

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of the present utility model. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present utility model.

[0026] To address the problems of viscous material accumulating into clumps and low sorting accuracy caused by the lack of a dedicated processing mechanism in traditional conveyor belt systems, the device in this embodiment overcomes the limitations of fixed dispersion by using adjustable-spacing rake teeth 3-4 and a staggered distribution structure. This allows operators to reduce the spacing of the rake teeth 3-4 to enhance shearing force for highly viscous materials such as citrus segments, or to increase the spacing for fragile materials such as blueberries to prevent excessive damage. Simultaneously, by utilizing the multiple sets of height threaded holes on the diversion rake assembly mounting adjustment plate 2-1 and the mounting holes on the side of the conveyor belt mounting platform 1-1, precise three-degree-of-freedom adjustment of longitudinal height, horizontal position, and the spacing of the multiple diversion rakes is achieved. This allows the same device to efficiently adapt to different working conditions and optimize the dispersing depth in real time based on the thickness of the material accumulation. Furthermore, the counter-rotating design of the diversion rake assembly 2-4 and the conveyor belt 1-2 enhances the penetration force against viscous clumps. Combined with the welded structure of the square tube sleeve and the rake teeth, the risk of loosening and falling off traditional assembled rake teeth is completely eliminated. This significantly reduces the failure rate and extends the maintenance cycle in a fruit processing plant operating continuously for 24 hours.

[0027] like Figure 1 The material dispersing device shown includes a conveyor belt 1-2, a dispersing drive device 1-4, a diverting rake assembly mounting limit frame 1-3, and a diverting rake 2-4. The diverting rake 2-4 is suspended above the conveyor belt 1-2 through the diverting rake assembly mounting limit frame 1-3, and the dispersing drive device 1-4 is electrically connected to the diverting rake 2-4.

[0028] The dispersing drive device 1-4 includes a motor 2-5, a motor mounting plate 2-3, a speed controller, and a power supply. For example... Figure 2 As shown, the diverting rake 2-4 includes a bearing housing 3-1, a coupling 3-2, a transmission shaft 3-3, and rake teeth 3-4. A square tube sleeve is fixed on the rotating shaft 3-3, and the rake teeth 3-4 are welded to the square tube sleeve. The diverting rake assembly mounting limit frame 1-3 is fixed on the conveyor belt mounting platform 1-1 on both sides of the conveyor belt 1-2, and the upper end is fixed with the diverting rake assembly mounting adjustment plate 2-1.

[0029] The square tube sleeve is a cuboid with four sides. Rake teeth 3-4 are evenly distributed on each side, with the spacing determined by the material being selected. The rake teeth 3-4 on any side of the square tube sleeve are staggered from those on adjacent sides, and the rake teeth 3-4 on opposite sides are aligned on the same straight line. The rake teeth 3-4 are cylindrical or square metal strips. The rotation direction of the diverting rake 2-4 is opposite to the running direction of the conveyor belt 1-2.

[0030] For materials of different types and sizes, the distance between the diverting rake 2-4 and the conveyor belt 1-2 can be flexibly adjusted. To match the speed of the conveyor belt 1-2 on different production lines, the position of the diverting rake 2-4 on the conveyor belt 1-2 can be arbitrarily adjusted. The bearing seat 3-1 is connected to the diverting rake assembly mounting adjustment plate 2-1 through threaded holes and screws. The diverting rake assembly mounting adjustment plate 2-1 has multiple sets of threaded holes of different heights for adjusting the distance between the diverting rake 2-4 and the conveyor belt 1-2, allowing a single material to pass through while preventing clumps of multiple materials from passing through. The height difference between the diverting rake 2-4 and the conveyor belt 1-2 is continuously adjusted by the diverting rake assembly mounting adjustment plate 2-1. Multiple sets of mounting holes for the diverting rake assembly mounting limit frame 1-3 are provided on both sides of the conveyor belt mounting platform 1-1 to adjust the spacing of each diverting rake 2-4. Depending on the adhesion of the material, multiple sets of dispersing devices can be used, and multiple diverting rakes 2-4 can be set on the conveyor belt 1-2.

[0031] like Figure 3 As shown, bearing housings 3-1 are respectively located at both ends of the rotating shaft 3-3, and coupling 3-2 is located on the side of motor 2-5 to connect bearing housings 3-1 and motor 2-5.

[0032] In the actual material dispersing process, the number of diverting rakes 2-4, the spacing between diverting rakes 2-4, the spacing between rake teeth 3-4, and the distance between diverting rakes 2-4 and conveyor belt 1-2 are selected according to the degree of adhesion of the material and the size of individual materials. Power is turned on and the speed is adjusted via a speed controller; the rotation direction of diverting rakes 2-4 is opposite to that of conveyor belt 1-2. When materials pass through diverting rakes 2-4, they are separated by the impact of rake teeth 3-4. Simultaneously, the spacing between rake teeth 3-4 controls the allowable dimensions of the materials to pass through, ensuring that materials of the appropriate size can pass.

[0033] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
