Abstract
Description
Technical Field
[0001] This utility model relates to the field of screening technology, and in particular to a sorting device for pre-processed food. Background Technology
[0002] Pre-prepared food processing refers to food that has been pre-treated, partially or fully cooked, and then preserved through freezing, refrigeration, or vacuum packaging. Among the many ingredients, potatoes are screened before use to remove those that do not meet the required specifications.
[0003] Currently, most potato sorting in existing pre-processed food manufacturing is done manually. However, manual sorting is slow and cannot effectively distinguish potatoes of different sizes, resulting in poor sorting results and affecting subsequent use. Utility Model Content
[0004] The purpose of this invention is to solve the problems of slow progress and poor screening effect of existing manual screening, and to propose a sorting device for pre-made food processing.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A sorting device for pre-processed food includes a box body. The bottom of the box body has multiple guide troughs, and the top of the box body is fixedly connected to a feeding hopper. Multiple water inlet pipes are fixedly connected between the inner walls of both sides of the feeding hopper. Multiple spray nozzles are inserted into one side of each water inlet pipe. A filter screen and a guide plate are fixedly connected between the inner walls of both sides of the box body. Two mounting blocks are fixedly connected between the inner walls of both sides of the box body. Two gears are rotatably inserted into one side of each mounting block via a rotating shaft. A toothed belt is drivingly connected between the two gears. Multiple push rods are fixedly connected between the two toothed belts. A screening plate is fixedly connected between the two mounting blocks. The push rods move on the screening plate, which has multiple first screening holes, second screening holes, and third screening holes.
[0007] Furthermore, an observation window is embedded on one side of the housing.
[0008] Furthermore, the filter screen and the guide plate are inclined, and the filter screen and the guide plate form a V-shaped structure.
[0009] Furthermore, a motor is fixedly connected to one side of the outer wall of the housing, and the output end of the motor is fixedly connected to one end of the rotating shaft of one of the gears.
[0010] Furthermore, the apertures of the first sieve hole, the second sieve hole, and the third sieve hole are different.
[0011] Furthermore, a collection box is placed at the bottom of the feed trough.
[0012] Furthermore, the filter screen is located below the feed hopper.
[0013] The beneficial effects of this utility model are as follows:
[0014] 1. Driven by a motor, the gears rotate, which in turn drives the toothed belt to rotate, which in turn drives the push rod to move. This pushes the potatoes to move on the screening plate, allowing potatoes of different sizes to be screened through the first screening hole, the second screening hole, and the third screening hole, thereby achieving automatic screening of potatoes of different sizes.
[0015] 2. Water is pumped into the inlet pipe and then sprayed onto the potatoes from the spray nozzles to clean them for subsequent sorting. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0022] Reference Figures 1-4A sorting device for pre-processed food includes a box body 1. The bottom of the box body 1 is provided with multiple guide troughs 3. A collection box 4 is placed at the bottom of the guide troughs 3. Potatoes fall into the collection box 4 along the guide troughs 3 and are collected. A feed hopper 5 is welded to the top of the box body 1. Multiple water inlet pipes 6 are fixed between the inner walls of the two sides of the feed hopper 5 by bolts. Multiple spray heads 7 are inserted into one side of the water inlet pipes 6. Water is input into the water inlet pipes 6 under the action of the pump body and then sprayed onto the potatoes from the spray heads 7 to clean the potatoes. A filter screen 8 and a guide plate 9 are fixed between the inner walls of the two sides of the box body 1 by bolts. One end of the guide plate 9 extends out of the box body 1, and the wastewater generated during cleaning is discharged from the box body 1 along the guide plate 9.
[0023] Two mounting blocks 10 are bolted between the inner walls of both sides of the housing 1. Two gears 11 are rotatably inserted into one side of the mounting blocks 10 via a rotating shaft. A toothed belt 13 is connected between the two gears 11. Multiple push rods 14 are bolted between the two toothed belts 13. A screening plate 15 is bolted between the two mounting blocks 10. The push rods 14 move on the screening plate 15. A motor 12 is bolted to the outer wall of one side of the housing 1. The output end of the motor 12 is fixedly connected to one end of the rotating shaft of one of the gears 11. The screening plate 15 is provided with multiple first screening holes 16, second screening holes 17, and third screening holes 18. Driven by the motor 12, the gears 11 rotate, thereby driving the toothed belt 13 to rotate, which in turn drives the push rods 14 to move, thus pushing the potatoes to move on the screening plate 15, so that potatoes of different sizes are screened through the first screening holes 16, second screening holes 17, and third screening holes 18.
[0024] An observation window 2 is embedded on one side of the box 1 to observe the screening of potatoes. The filter screen 8 and the guide plate 9 are inclined. The filter screen 8 and the guide plate 9 have a V-shaped structure. The diameters of the first screening hole 16, the second screening hole 17 and the third screening hole 18 are different. The filter screen 8 is located below the feed hopper 5.
[0025] The working principle of this embodiment is as follows: When in use, the water inlet pipe 6 is connected to the pump body. First, potatoes are put into the feed hopper 5. Then, the potatoes fall onto the filter screen 8. At the same time, the pump body is started, and water is input into the water inlet pipe 6 under the action of the pump body. Then, water is sprayed onto the potatoes from the spray head 7 to clean the potatoes. Then, the potatoes roll down the filter screen 8 onto the screening plate 15. The wastewater generated during cleaning is discharged from the box 1 along the guide plate 9 for centralized treatment. Next, the motor 12 is started. Under the drive of the motor 12, the gear 11 rotates, thereby driving the toothed belt 13 to rotate, which in turn drives the push rod 14 to move. This pushes the potatoes to move on the screening plate 15, so that potatoes of different sizes are screened through the first screening hole 16, the second screening hole 17, and the third screening hole 18. Then, the potatoes fall into the collection box 4 along the guide trough 3 for collection.
[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
