Description

TECHNICAL FIELD

[0001] The utility model relates to food processing equipment field especially push mechanism and have its drum screen. BACKGROUND

[0002] The drum screen is used for separating aquatic products and impurities efficiently in aquatic slaughter workshop. The application of the drum screen is closely related to improving production efficiency, ensuring product quality and meeting health requirements. Aquatic slaughter workshop usually needs to process a large amount of aquatic products (such as fish, shrimp, crab, etc.) and clean, process and package them. During these processes, aquatic products often need to go through multiple steps such as cleaning, scaling and removing internal organs to ensure that they meet food hygiene and safety standards. During the aquatic slaughter process, a large amount of impurities and residues such as internal organs, scales and bone spurs are often generated, especially in the cleaning link. These impurities will affect the appearance, quality of aquatic products and subsequent processing and packaging. Therefore, how to efficiently separate aquatic products and impurities is the key to improving production efficiency and product quality. The drum screen is a device that separates materials through rotating screen or drum. Through the rotating movement of the drum, aquatic products and impurities can be effectively separated. The drum screen can screen according to the size and shape of the material, helping to separate impurities (such as scales and internal organs) from aquatic products to ensure the cleanliness of aquatic products. Compared with manual screening, the drum screen can work efficiently and continuously, greatly improving the automation level of the production line and reducing manual intervention. The drum screen can handle aquatic products in a relatively gentle way to avoid damage or waste of aquatic products due to too violent operation.

[0003] However, the existing drum screen often encounters the following problems in use: when the existing drum screen screens aquatic food, it often faces a difficult-to-avoid problem, that is, due to the viscosity of aquatic food, the waste under the screen often cannot pass through the discharge plate quickly. Aquatic waste often contains rich internal organs, scales, residues and other substances. These materials are sticky and moist, and are easy to adhere to the surface of the discharge shell, causing material accumulation and smooth discharge. Once the waste is accumulated and stays in the screening equipment for a long time, the moisture and organic components of the waste will promote the growth of bacteria and produce foul odor, which not only affects the normal operation of the equipment, but also may cause food safety hazards. Especially in a high-temperature and humid environment, aquatic waste is more prone to spoilage, producing harmful gases and increasing the potential risk to the environment and the health of workers.

For the ordinary skilled in the art, the specific meaning of the above terms in the present utility model should be understood according to the specific circumstances.

[0037] As shown in FIG. Figs. 1-3 A pushing mechanism and a drum screen with the same, comprising: a drum screen 1, a discharge shell 2, a drainage groove 3, a pushing plate 4, a sliding rail 5, a sliding shell 6, and a pushing mechanism 7. The discharge shell 2 is installed on the legs of the drum screen 1, and the discharge shell 2 is installed obliquely on the legs of the drum screen 1. The drainage groove 3 is provided on the discharge shell 2, the pushing plate 4 is located in the drainage groove 3, the pushing plate 4 is in a vertical position relationship with the inner wall of the drainage groove 3, the sliding rail 5 is arranged on the inner wall of one side of the drainage groove 3, the extension trend of the sliding rail 5 is parallel to the discharge shell 2, the sliding shell 6 is placed on the side lip of the drainage groove 3, one side of the sliding shell 6 is connected with the pushing plate 4, and the sliding shell 6 is slidably connected with the sliding rail 5, and the pushing mechanism 7 is provided in two groups, and each group of the pushing mechanism 7 is movably connected with the top surface of the sliding shell 6, and the pushing mechanism 7 drives the sliding shell 6 to slide along the sliding rail 5. The two groups of pushing mechanisms 7 are obliquely parallel to the discharge shell 2.

[0038] In the present utility model, the arrangement of the sliding rail 5 ensures that the sliding shell 6 can stably slide along the track during the pushing process, avoiding unnecessary friction loss. The connection mode of the sliding shell 6 and the pushing plate 4 enables the pushing plate 4 to stably and effectively push the materials. The parallel working mode of the two groups of pushing mechanisms 7 can provide more uniform power output, while avoiding the failure of the single pushing mechanism 7 due to overload or failure, thereby avoiding the failure of the whole system. The parallel design enables the burden of each group of pushing mechanisms 7 to be shared, thereby increasing the stability and reliability of the system.

[0039] The utility model discloses, in order to make reciprocating motion setting push mechanism 7 of pushing plate 4, include: the outside fixed mounting of connecting shell 71 is installed in the material discharge casing 2, first connecting rod 72 one end swing installation is in connecting shell 71, first driven gear 73 is installed in the other end of first connecting rod 72, and first driven gear 73 is located above first connecting rod 72. Second driven gear 74 is located in the extension direction of the side wheel surface of first driven gear 73, and first driven gear 73 is engaged with second driven gear 74, and one end of second connecting rod 75 is swing connected with the wheel surface axis of second driven gear 74, and the other end of second connecting rod 75 is swing connected with the top surface of sliding shell 6, and one end of linkage plate 76 is connected with the axle wheel surface of first driven gear 73, and the other end of the bottom surface of linkage plate 76 is connected with the axle wheel surface of second driven gear 74. The design of gear linkage and connecting rod structure is adopted, and the main purpose is to realize stable power transmission. The high transmission ratio of the gear system can convert the rotary power of the driving motor 8 into reciprocating linear motion of the pushing plate 4. The cooperation design of the gear and the connecting rod ensures uniform distribution of power, reduces mechanical wear and tear, and improves the reliability of the system. In addition, the gear and connecting rod structure makes the whole push mechanism 7 have strong load capacity, which can effectively prevent system failure caused by overload during pushing.

[0040] In the utility model, since the gear system needs to bear a large transmission torque, the material of the gear and the connecting rod requires high strength, toughness and wear resistance. Commonly used materials include alloy steel such as 45# steel, 40Cr steel and stainless steel such as 304 stainless steel. These materials have high hardness and good corrosion resistance, and are suitable for high-load and high-frequency operation gear transmission systems. The connecting rod needs to have high tensile strength and fatigue resistance, and is usually made of medium carbon steel or low alloy steel, such as 40Cr or 35CrMo steel. For places with high load capacity requirements, heat-treated steel such as carburizing steel may be used to further improve the surface hardness and wear resistance and prolong the service life.

[0041] The output end of the driving motor 8 is axially connected to one end of the first connecting rod 72, and the other end of the first connecting rod 72 in the two groups of push mechanisms 7 is connected through the two ends of the parallel plate 9. The connecting end of the parallel plate 9 and the first connecting rod 72 is located below the first connecting rod 72. The push mechanism drives the two groups of push mechanisms 7 to work through the driving motor 8, and the output of each group of push mechanisms 7 is transmitted through the parallel plate 9 to coordinate the sliding of the pushing plate 4 along the direction of the drainage groove 3, thereby realizing efficient pushing of the material. This design not only ensures smooth discharge of the material, but also avoids blockage when handling high-viscosity materials. The push mechanism can further optimize the discharge effect by adjusting the power of the driving motor 8 and adjusting the gear transmission ratio to adapt to the discharge requirements of different types of materials.

[0042] The drum screen 1 utilizes a pushing mechanism, passes through the efficient pushing mechanism 7, adopts the linkage structure of gear and connecting rod, and can realize the stable reciprocating movement of the pushing plate 4. The design can effectively push the screened aquatic waste to the discharge port, and avoid that the waste is retained in the equipment due to viscosity. The reciprocating movement makes the pushing plate 4 continuously push the waste to flow along the discharge shell, ensures that the waste is not easily adhered to the screen or the discharge shell, and solves the problem of material accumulation.

[0043] It should be noted that the pushing mechanism and the drum screen with the same are designed by the utility model, and when used, once the food screened by the drum screen 1 is seafood, relatively viscous scales or visceral fragments will be screened and fall into the drainage groove 3 of the discharge shell body 2, one barrel is placed at each end of the drainage groove 3 in the extension discharge direction, the driving motor 8 is set to reciprocating axial rotation, the driving motor 8 drives one set of pushing mechanism 7 to drive the other set of pushing mechanism 7 to reciprocate through the parallel plate 9, and then the pushing plate 4 is driven to slide in the drainage groove 3 along the drainage groove 3 through the pushing mechanism 7. If the driving motor 8 rotates clockwise, the first connecting rod 72 rotates, the first connecting rod 72 drives the first driven gear 73 installed at one end of the first connecting rod 72, the first driven gear 73 revolves due to the driving of the first connecting rod 72, the first driven gear 73 drives the second driven gear 74 to rotate, the second driven gear 74 drives the second connecting rod 75 connected with the second driven gear 74 to expand outward, the second connecting rod 75 drives the sliding shell 6 to move linearly under the guidance of the slide rail 5, and the sliding shell 6 drives the pushing plate 4 to slide in the drainage groove 3 along the drainage groove 3, so that the material in the drainage groove 3 is quickly pushed out of the drainage groove 3. The discharge is completed.

[0044] Although the embodiments of the utility model have been shown and described, for those skilled in the art, it is understood that various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and spirits of the utility model, the scope of the utility model is defined by the appended claims and their equivalents.
