Description
Technical Field
[0001] This utility model relates to the field of food processing technology, specifically to a pre-draining device for the tail end of a meat product conveyor belt. Background Technology
[0002] In the deep processing of poultry products, the surface of cleaned and cut poultry products (such as chicken breast and chicken leg pieces) often has a large amount of moisture attached, requiring pre-draining when conveyed to the end. Existing equipment has significant drawbacks: direct material receiving results in high moisture residue, increasing processing time for subsequent marinating and drying processes; some simple draining structures lack directional flow design, resulting in a draining efficiency of less than 30%; poultry processing easily generates residues such as bone fragments and tendons, and existing equipment lacks a filtration structure, allowing these residues to mix with accumulated water and easily clog the drain outlets, increasing cleaning frequency; furthermore, the irregular shape of poultry pieces makes them prone to shifting from the sides of the discharge rack during conveying, leading to insufficient draining in certain areas. Therefore, there is an urgent need for a pre-draining device suitable for poultry products that can efficiently drain water, filter residues, and prevent shifting. Utility Model Content
[0003] The purpose of this utility model is to provide a pre-draining device for the tail end of a meat product conveyor belt, so as to solve the defects of existing similar equipment. The meat products are conveyed to the discharge bar by the conveyor belt, and the inclined structure combined with the guide groove allows the water to flow down quickly. After being filtered by the slag collection screen box, the water flows into the water collection tray, realizing pre-draining and improving the efficiency of subsequent processing.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a pre-draining device for the tail end of a meat product conveyor belt, comprising a fork-type discharge rack disposed at the tail end of the conveyor belt, wherein the fork-type discharge rack is provided with a discharge channel, one end of the discharge channel is connected to the discharge end of the conveyor belt, and the other end of the discharge channel is connected to a receiving bucket, wherein a slag collection mesh box and a water collection tray are arranged sequentially from top to bottom below the fork-type discharge rack, the fork-type discharge rack includes guard plates located on both sides, and multiple discharge rods are arranged side by side at intervals between the two guard plates, the discharge rods are arranged along the material conveying direction, and the lower end of the discharge rods extends into the receiving bucket; the discharge rods are inclined structures, and the end of the discharge rod closer to the conveyor belt is higher than the end extending into the receiving bucket, and a guide groove extending along its length is opened on the upper surface of the discharge rod, the bottom of the guide groove is inclined towards the two sides of the discharge rod.
[0005] To further optimize this utility model, the following technical solutions may be preferred: Preferably, a crossbar is provided between the two guard plates at the top position corresponding to the material drop bar.

Detailed Implementation
[0018] 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 embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with specific embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of this utility model.
[0020] Example 1: like Figure 1-5As shown, a pre-draining device for the tail end of a meat product conveyor belt is described. During assembly, the two side guard plates 3 of the fork-type discharge rack 2 are first bolted to a pre-set bracket at the tail end of the conveyor belt 1. The guard plates are made of stainless steel with a thickness of 3-5mm to ensure sufficient resistance to materials. Twelve discharge rods 4 are arranged side-by-side between the two guard plates 3 at intervals. The discharge rods are made of food-grade stainless steel with a diameter of 8-10mm, and the spacing between adjacent discharge rods 4 is 10mm. The discharge rods are arranged along the material conveying direction.
[0021] The discharge bar has an inclined structure, with its end near the conveyor belt higher than the end extending into the receiving hopper 5. The inclination angle is set at 18°, which ensures that the material slides down smoothly and provides sufficient time for drainage. The upper surface of the discharge bar 4 has a guide groove 6 extending along its length. The guide groove is 4mm wide, and the bottom of the guide groove is inclined towards the two sides of the discharge bar at an inclination angle of 5°, which can quickly guide the water on the surface of the material to flow to both sides of the discharge bar and drip down.
[0022] A crossbar 7 is installed between the two guard plates 3 at the top position of the material drop bar. The crossbar is welded to the material drop bar, and a triangular reinforcing rib 8 with a thickness of 2mm is provided at the weld to enhance the stability of the connection between the material drop bar and the crossbar. The two ends of the crossbar are fixed to the guard plates by detachable connectors 9. The detachable connectors are bolt assemblies with anti-loosening nuts to facilitate future maintenance or replacement of the material drop bar.
[0023] The portion of the material discharge rod extending into the receiving hopper is fitted with a silicone buffer sleeve 10. The buffer sleeve is 2.5mm thick and has spiral anti-slip texture 11 on its outer surface with a spiral spacing of 5mm, which prolongs the sliding time of the material on the discharge rod. The buffer sleeve also has evenly distributed through-hole drainage micropores 12 with a diameter of 1mm, which can further drain the surface moisture of the material. The edge of the receiving hopper opening is provided with an annular guide edge 13, which is 40mm wide and has 8 circumferentially distributed guide grooves 14. The ends of the guide grooves extend directly above the water receiving tray to prevent water from remaining at the hopper opening.
[0024] Below the forklift discharge rack, from top to bottom, are arranged a slag receiving screen box 15 and a water receiving tray 16. The slag receiving screen box is installed below the conveyor belt at both ends via a quick-release structure. The quick-release structure includes L-shaped hooks 17 at both ends of the slag receiving screen box and corresponding U-shaped slots 18 below the conveyor belt. The L-shaped hooks and U-shaped slots engage to facilitate quick assembly and disassembly of the slag receiving screen box. The bottom of the slag receiving screen box has a V-shaped structure with a V-angle of 30°, and the inner side wall of the screen box has a guide rib 19 that slopes towards the bottom of the V-shape. The guide rib has a height of 2mm and can guide the residue to converge towards the bottom of the V-shape to prevent residue accumulation.
[0025] The water collection tray has a pull-out structure with sliders on both sides. A corresponding slide rail is provided at the bottom of the fork-type discharge rack, allowing the sliders and rails to slide smoothly together for easy removal of the tray for cleaning. The bottom of the tray has a drain outlet 21 with a control valve and a diameter of 15mm. Inside the tray, along its length, is a guide plate 20 inclined at an 8° angle towards the drain outlet to guide accumulated water towards it. A level sensor is installed inside the tray, and an alarm indicator light electrically connected to the sensor is located on the outside. When the water level in the tray reaches 80% of its capacity, the alarm indicator light illuminates, reminding the operator to drain the water promptly.
[0026] In operation, meat products enter the discharge channel from the outlet of conveyor belt 1, then fall onto the discharge rod and slide along it towards the receiving hopper. During this sliding process, moisture on the surface of the meat products flows to both sides of the discharge rod and drips off under its own weight and the action of the guide channel. After being filtered by the slag collection screen, the moisture flows into the water collection tray, while bone fragments, fascia, and other residues are intercepted within the slag collection screen. When the water level in the water collection tray reaches the warning value, the alarm indicator light illuminates, and the operator can open the control valve at the drain outlet to drain the water. When it is necessary to clean the slag collection screen, it can be directly removed from the U-shaped slot.
[0027] 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.
