Description

Technical Field

[0001] This utility model relates to the field of mushroom screening technology, and in particular to a mushroom screening device for processing canned edible fungi. Background Technology

[0002] In the edible mushroom canning industry, mushroom selection is one of the key steps to ensure product quality. To meet the production needs of canned edible mushrooms of different sizes, harvested mushrooms must be precisely graded and selected according to size to ensure uniformity in size within the same batch of canned goods, thereby improving product quality and market competitiveness. Currently, most edible mushroom screening devices on the market adopt a multi-layered horizontally arranged screening structure. This structure uses screens with different aperture sizes at different levels to grade and screen the mushrooms. However, this horizontal screening structure has significant drawbacks: firstly, the horizontally arranged multi-layered screens occupy a large amount of factory space, which undoubtedly increases production costs in modern production workshops where space is extremely limited; secondly, due to their structural characteristics, the outlets of each layer of screens in existing multi-layered screening devices can only be located at the same end of the device. This necessitates the installation of complex turning and diversion mechanisms when conveying mushrooms of different qualities and sizes to subsequent workstations, increasing equipment costs and potentially causing congestion in the conveying route, thus affecting the continuity and smoothness of the production process. Therefore, there is an urgent need for a mushroom screening device for edible mushroom canning that can reduce space occupation, improve space utilization while ensuring screening effect, and facilitate the transportation of materials to subsequent workstations. Utility Model Content

[0003] The purpose of this invention is to provide a mushroom screening device for processing edible fungi canned goods, which can reduce space occupation, improve space utilization while ensuring screening effect, and facilitate the transportation of materials to subsequent workstations.

[0004] The present invention adopts the following technical solution: A mushroom screening device for processing edible fungi into canned goods includes a frame. Multiple conveyor belts are inclinedly arranged along the length of the frame, with adjacent conveyor belts connected end-to-end. Each conveyor belt is inclined upwards from the inlet to the outlet. Each conveyor belt has screening holes, and the diameter of the screening holes gradually increases from front to back. A receiving section is provided on the frame below each conveyor belt, located between the upper and lower channels of each conveyor belt.

[0005] Preferably, the receiving part is provided on the frame located below the conveyor belt at the end.

[0006] Preferably, the receiving part is a belt conveyor, and the conveying direction of the belt conveyor is perpendicular to the frame.

[0007] Preferably, each of the conveyor belts is provided with an auxiliary unloading device on the frame above it.

[0008] Preferably, the auxiliary feeding component includes a support rod, on which multiple flexible plastic curtains are arranged along its length.

[0009] Preferably, the support rod is bolted to the side wall of the frame.

[0010] Preferably, the front end of the support rod is provided with a U-shaped frame, and multiple material leveling rods are spaced apart on the U-shaped frame along its length.

[0011] Preferably, the material leveling rod has a cylindrical structure.

[0012] Preferably, the U-shaped frame has an adjustment groove along its length, the upper part of the material leveling rod has an external thread, and the top of the material leveling rod passes through the adjustment groove and is connected to a washer and a locking nut.

[0013] Compared with existing technologies, the advantages of this invention are as follows: This invention utilizes multiple inclined conveyor belts arranged along the length of the frame, connected end-to-end and tilted upwards. Compared to traditional horizontal multi-layer screening structures, this three-dimensional inclined layout significantly reduces the horizontal space occupied in the factory, achieving multi-layer screening within a limited space and significantly improving space utilization. Simultaneously, the upward tilt of each conveyor belt from the inlet to the outlet allows the mushrooms to move naturally and smoothly on the belts during screening, aiding in the smooth passage of smaller mushrooms through the screening holes. The design of progressively increasing screening hole diameters on the multiple conveyor belts from front to back enables precise grading and screening of mushrooms, ensuring uniform specifications within the same batch and guaranteeing excellent screening results.

[0014] Furthermore, the unique layout of the receiving section on the frame beneath each conveyor belt, located between the upper and lower channels of the conveyor belt, allows for independent receiving of mushrooms of different sizes at multiple workstations after they fall into the receiving section through the corresponding screening holes. This design eliminates the need for additional complex steering and diversion mechanisms, enabling convenient transport of mushrooms of different qualities and sizes to their respective subsequent processes. This effectively avoids congestion along the conveyor route, ensures the continuity and smoothness of the production process, reduces equipment and maintenance costs, and significantly improves production efficiency and economic benefits. Attached Figure Description

[0015] Figure 1 This is a schematic diagram of the structure of an embodiment of this application; Figure 2 for Figure 1 A magnified view of A in the middle. Detailed Implementation

[0016] The present invention will now be described clearly and completely with reference to the accompanying drawings and embodiments: like Figures 1 to 2 As shown, the mushroom screening device for canned edible fungi of this utility model includes a frame 1. Multiple conveyor belts 2 are inclinedly arranged along the length of the frame 1. Each conveyor belt 2 can be driven independently by a motor; the operating frequency of the multiple motors can be adjusted during operation. Adjacent conveyor belts 2 are connected end-to-end, with the front end of the subsequent conveyor belt 2 extending to the lower part of the front end of the preceding conveyor belt 2, so that the mushrooms screened by the preceding conveyor belt 2 can fall smoothly onto the subsequent conveyor belt 2. Each conveyor belt 2 is inclined upwards from the inlet to the outlet, which helps to screen and drop small-sized mushrooms. Each conveyor belt 2 is provided with screening holes 3, and the diameter of the screening holes 3 on the multiple conveyor belts 2 gradually increases from front to back, allowing for precise grading and screening of mushrooms, ensuring uniform specifications of mushrooms screened in the same batch, and guaranteeing good screening results. A receiving part 4 is provided on the frame 1 below each conveyor belt 2, thus enabling independent receiving of materials at multiple workstations. This design eliminates the need for complex steering and diversion mechanisms, allowing for the convenient transport of mushrooms of varying qualities and sizes from the screening process to subsequent steps. This effectively avoids congestion along the transport route, ensuring the continuity and smoothness of the production flow, reducing equipment and maintenance costs, and significantly improving production efficiency and economic benefits. Furthermore, the receiving section 4 is located between the upper and lower channels of each conveyor belt 2. This arrangement prevents the conveyor belt 2 from obstructing the fall of the screened mushrooms when it rotates to the bottom. Rotating rollers are installed at the bottom of the frame 1, located on both sides of each receiving section 4, to ensure the normal operation of the conveyor belt 2.

[0017] In addition, a receiving section 4 is provided on the frame 1 below the conveyor belt 2 at the end, for receiving the mushrooms that are screened out last. The receiving section 4 is a belt conveyor, and the conveying direction of the belt conveyor is perpendicular to the frame 1, so as to promptly transport the screened mushrooms to the subsequent processing steps, avoiding the complicated operations caused by transfer, realizing precise connection of the entire processing process, and improving processing efficiency.

[0018] Furthermore, each frame 1 above the conveyor belt 2 is equipped with an auxiliary feeding component to assist mushrooms smaller than the screening holes 3 on the corresponding conveyor belt 2 to be smoothly screened out and fall, thereby improving the screening effect. Preferably, the auxiliary feeding component includes a support rod 5, which is set between the two side walls of the frame 1. Multiple flexible plastic curtains 6 are arranged along the length of the support rod 5. The bottom of the plastic curtain 6 initially leaves a gap with the corresponding conveyor belt 2, but the gap is smaller than the size of the mushroom. During the screening process, if small-sized mushrooms get stuck in the screening holes 3 or stay on the conveyor belt 2 outside the screening holes 3, the mushrooms can come into contact with the plastic curtains 6 as the conveyor belt 2 is conveyed. The plastic curtains 6 increase the resistance to the movement of the mushrooms, and the small-sized mushrooms will be pushed into the screening holes 3 and fall out from the screening holes 3. Large-sized mushrooms will pass through the plastic curtains 6 and run onto the subsequent conveyor belt 2, thus effectively improving the screening accuracy.

[0019] Specifically, mounting plates 7 are provided at both ends of the support rod 5, and the mounting plates 7 are bolted to the side wall of the frame 1. This arrangement facilitates the removal of the support rod 5 for targeted replacement of the plastic curtain 6. In addition, a U-shaped frame 8 is provided at the front end of the support rod 5, and multiple material distribution rods 9 are spaced apart along the length of the U-shaped frame 8. The distance between two adjacent material distribution rods 9 is greater than the smallest mushroom size. The material distribution rods 9 help to disperse the mushrooms that have gathered and fallen onto the conveyor belt 2, so that they are evenly distributed to improve the screening effect. The material distribution rods 9 are preferably cylindrical to reduce wear caused by the movement of mushrooms. An adjustment groove 10 is also provided along the length of the U-shaped frame 8. The upper part of the material distribution rod 9 is provided with an external thread. After the top of the material distribution rod 9 passes through the adjustment groove 10, a gasket 11 is fitted on it. A locking nut 12 is provided on the material distribution rod 9 above the gasket 11. When screening different types of mushrooms, the uniform feeding rod 9 can be adjusted in the adjustment groove 10 to adjust the distance between two adjacent uniform feeding rods 9 to ensure that the mushrooms pass through smoothly, thereby enhancing the practicality of this utility model and expanding its scope of application.

[0020] In use, the mushrooms to be screened are simply poured onto the conveyor belt 2 at the front end. As the conveyor belt 2 moves, smaller mushrooms will be screened out and fall onto the receiving part 4 below. The receiving part 4 will then transport them to the subsequent processing steps as needed. The entire device has a simple structure, is easy to operate and use, and is highly practical.
