Abstract
Description
Technical Field
[0001] This utility model relates to the field of food sorting technology, and in particular to a food sorting device. Background Technology
[0002] Ingredients are processed into food for people to eat / drink. The process of processing ingredients often involves picking, washing, drying, sorting, and further processing. Among these, the selection of ingredients directly determines the quality of the processed food. The selection is often based on the size of the ingredients, which are divided into multiple grades. Currently, most small and medium-sized food processing enterprises use manual sorting, which is inefficient and labor-intensive.
[0003] For example, Chinese utility model patent (CN211027124U) discloses a high-quality food sorting production line, which describes: "It includes a support frame, roller one, roller two, and a conveyor belt between roller one and roller two. The support frame is equipped with a detection component, a pushing component for pushing high-quality food, and a storage box for receiving the pushed high-quality food. The detection component includes a vertical plate and a horizontal plate fixed together. The vertical plate is located on one side of the conveyor belt along its length, and the horizontal plate is located directly above the conveyor belt along its length. A horizontal chute and a vertical chute are opened on the end face of the vertical plate near the conveyor belt. Two sensors are slidably installed in the horizontal chute for detecting the length of the food, and a sensor is slidably installed in the vertical chute for detecting the height of the food. A top chute parallel to the width direction of the conveyor belt is opened on the lower end face of the horizontal plate. Two sensors are slidably installed in the top chute for detecting the width of the food."

However, when the food ingredients are small, such as sorting beans, the detection effect of using multiple sensors for sorting is poor and the sorting efficiency is extremely low. Therefore, this application proposes a food sorter. Utility Model Content

[0028] The food sorting device provided by this utility model, through its overall structural design, enables the rapid sorting of small food items using a multi-stage screening method.

[0029] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.
[0030] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0031] Example 1:
[0032] Please refer to Figure 1-6 A food sorting device includes a screening box 1. In order to transport small-sized food into the screening box 1 for sorting, a first conveying device 2 is installed at the upper end of the screening box 1. In order to prevent food from falling, a baffle 3 is provided at one end of the first conveying device 2. The baffle 3 is fixed to the screening box 1.
[0033] To transport sorted ingredients of different sizes outward, the lower end of the screening box 1 is provided with a first discharge port 4, a second discharge port 5, and a third discharge port 6. The lower ends of the first discharge port 4, the second discharge port 5, and the third discharge port 6 are all provided with a second conveying device 7. In order to realize multi-stage screening and sorting, a first partition 8 is provided between the first discharge port 4 and the second discharge port 5, and a second partition 9 is provided between the second discharge port 5 and the third discharge port 6. The first partition 8 and the second partition 9 are fixed to the screening box 1. The first guide trough 10 and the second guide trough 11 are respectively provided inside the first partition 8 and the second partition 9. A first support frame 14 is provided at the upper end of the first discharge port 4, and a second support frame 16 is provided at the upper end of the second discharge port 5. A first screen 15 is fixed inside the first support frame 14, and a second screen 17 is fixed inside the second support frame 16.
[0034] Furthermore, the first support frame 14 is located at the upper end of the first guide trough 10, and the second support frame 16 is located at the upper end of the second guide trough 11, so that when the food falls to the upper end of the first screen 15 and the second screen 17, it will not fall down through the first guide trough 10 or the second guide trough 11 immediately, allowing sufficient screening time. After the food has been fully screened, in order to move the first support frame 14 and the second support frame 16 down to facilitate the discharge of the food through the first guide trough 10 and the second guide trough 11, the bottom end of the first conveying device 2 is respectively equipped with a first electric telescopic rod 18 and a second electric telescopic rod 19. The telescopic end of the first electric telescopic rod 18 is fixed to the first support frame 14, and the telescopic end of the second electric telescopic rod 19 is fixed to the second support frame 16.
[0035] In order to guide the screened ingredients to accurately enter the first discharge port 4, the second discharge port 5, or the third discharge port 6, guide plates 12 are provided at both ends of the upper part of the first discharge port 4, the second discharge port 5, and the third discharge port 6. The guide plates 12 are fixed to the screening box 1. In order to guide the lifting and moving of the first support frame 14 and the second support frame 16 and improve their moving stability, guide posts 13 are provided at the four corners of the upper part of the first discharge port 4 and the second discharge port 5. The guide posts 13 are fixed to the guide plates 12, and the first support frame 14 and the second support frame 16 are slidably connected to the guide posts 13.
[0036] Example 2:
[0037] The food sorting device provided in Example 1 has been further optimized, specifically, as follows: Figure 4-6 As shown, when the ingredients are screened on the upper part of the first screen 15 and the second screen 17, in order to speed up the screening and improve the screening efficiency, the lower end of the first support frame 14 and the second support frame 16 are provided with vibration components, and when the first support frame 14 and the second support frame 16 move up and down, the vibration components move synchronously with them.
[0038] Specifically, each vibration component includes a mounting frame 20. The lower ends of the first support frame 14 and the second support frame 16 are fixed with the mounting frame 20. The mounting frame 20 is slidably connected to the guide post 13. The inner side of each mounting frame 20 is slidably connected to a movable frame 21. The upper end of the movable frame 21 is fixed with two top posts 22. The inner side of each mounting frame 20 is fixed with a reduction motor 23. The output end of the reduction motor 23 is fixed with a support plate 24. The inside of the support plate 24 is provided with a drive cavity 25. The inside of the drive cavity 25 is provided with a support shaft 27. The end of the support shaft 27 away from the support plate 24 is located inside the movable frame 21 and is movably connected to the movable frame 21.
[0039] In order to facilitate the adjustment of the amplitude according to the different ingredients being screened and the blockage of the first screen 15 and the second screen 17, a third electric telescopic rod 26 is provided on the inner side of each drive cavity 25. The third electric telescopic rod 26 is fixed to the support plate 24, and the telescopic end of the third electric telescopic rod 26 is fixed to the support shaft 27. The support shaft 27 is slidably connected to the drive cavity 25.
[0040] All of the above electrical components are electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that performs control, and the existing publicly available power connection technology will not be described in detail here.
[0041] The mechanical transmission components provided in this utility model are all closed designs that can be opened for maintenance. According to the mechanical manual, as long as they are properly maintained, these mechanical transmission components can normally realize the transmission motion claimed above.
[0042] The process of using the food sorter provided by this utility model is as follows: After the food is conveyed to the screening box 1 by the first conveying device 2, the food first falls to the upper end of the first screen 15. With the cooperation of the vibration component, the first screen 15 is shaken quickly to accelerate the screening, so that the smaller food falls into the first discharge port 4 and is conveyed outward by the second conveying device 7.
[0043] After a period of screening, once the ingredients on the first screen 15 have been screened, the first electric telescopic rod 18 is activated to move the first support frame 14 downward, thereby positioning the first guide chute 10 above the first screen 15. This allows the ingredients to be discharged through the first guide chute 10 to the upper end of the second screen 17, where they are then screened again in conjunction with the vibration component. This causes smaller and ordinary-sized ingredients to fall into the second discharge port 5 and be conveyed outwards through the second conveying device 7.
[0044] After the second screening is completed, the second electric telescopic rod 19 is activated to drive the second support frame 16 to move down, so that the larger-sized ingredients are directly discharged into the third discharge port 6 through the second guide trough 11, and then conveyed outward through the second conveying device 7 to complete the grading and sorting of ingredients. The sorting efficiency is high, and there is no need to sort the ingredients by checking their length, width and height in turn.
[0045] When the vibration assembly needs to be operated, the geared motor 23 is started to drive the support plate 24 to rotate, causing the support shaft 27 to rotate. Utilizing the movable connection between the support shaft 27 and the movable frame 21, the movable frame 21 is driven to reciprocate up and down inside the mounting frame 20. This causes the top column 22 to repeatedly contact the first screen 15 or the second screen 17, causing them to vibrate. The third electric telescopic rod 26 controls the movement of the support shaft 27 inside the drive cavity 25, facilitating the adjustment of the rotation circumference of the support shaft 27. This changes the lifting and lowering stroke of the movable frame 21, thereby adjusting the vibration amplitude.
