Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0026] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0027] like Figures 1 to 5 As shown, this application provides a sand and gravel removal device for intelligent sorting of food ingredients based on photoelectric sensing, including:

[0028] The sorting equipment 100 includes a belt conveyor 10, a dispersing mechanism 20, a primary screening mechanism 30, and a control main board 48. A column 11 is fixedly installed on one side of the belt conveyor 10. A connecting rod 12 is fixedly installed on the outer wall of the middle part of the column 11, and a connecting rod 23 is fixedly installed on one side of the upper end of the column 11. The primary screening mechanism 30 is fixedly installed on one side of the column 11, located directly above the belt conveyor 10. The dispersing mechanism 20 is fixedly installed on one side of the connecting rod 23. The sorting mechanism 40 is located at the lower end of one side of the primary screening mechanism 30 and includes a sorting cylinder 41 fixedly installed at the bottom of the primary screening mechanism 30. A protective shell 42 is fixedly installed on one side. An X-ray receiver 44 is fixedly installed on the inner wall of the upper end of the sorting cylinder 41. An X-ray transmitter 43 is fixedly installed on the upper end of the protective shell 42. The X-ray transmitter 43 and the X-ray receiver 44 are arranged at an angle. A nozzle 45 and an air pump 46 are fixedly installed on the lower end of the protective shell 42. The input end of the nozzle 45 is connected to the output end of the air pump 46 through a hose. A discharge hole 47 is provided on the outer wall of one side of the sorting cylinder 41. The discharge hole 47 is at the same horizontal line as the nozzle 45 and is located below the X-ray receiver 44. The control main board 48 is fixedly installed inside the protective shell 42.

[0029] After adopting the above technical solution, the food ingredients and sand to be sorted are dispersed by the dispersion mechanism 20. The dispersed food ingredients and sand enter the upper surface of the primary screening mechanism 30 at the same time. The primary screening mechanism 30 screens out the fine sand and gravel, thereby reducing the detection range of the equipment. The remaining food ingredients and large sand and gravel mixture are sent to the sorting cylinder 41. Since the opening of the sorting cylinder 41 is small, only a small amount of food ingredients and sand and gravel can pass through at one time, which further reduces the detection range of the equipment. When the food ingredients and large sand and gravel fall along the inner wall of the sorting cylinder 41, X-rays are emitted by the X-ray emitter 43 to irradiate the food ingredients and sand and gravel, and the reflected light is received by the X-ray receiver 44. The X-ray receiving process is performed. Since food and sand have different absorption properties for X-rays, they can be sorted by the intensity of the reflected X-rays. The main board 48 analyzes the reflected signals. When food is identified as passing through, an electrical signal is sent to the air pump 46. After receiving the electrical signal, the air pump 46 pumps air into the nozzle 45. The nozzle 45 sprays high-pressure gas, which causes the food to enter the upper surface of the belt conveyor 10 through the discharge hole 47, while the sand enters the bottom of the sorting cylinder 41. By performing preliminary screening of food and sand and controlling the detection entrance, the scope of equipment inspection is reduced, thereby reducing the required accuracy and cost of the equipment.

[0030] It should be noted that when the ingredients and sand mixture to be sorted are placed inside the hopper 22, the dispersing motor 24 drives the dispersing roller 23 to rotate, thereby dispersing the ingredients and sand to prevent sand from embedding into the outer wall of the ingredients and affecting the sorting results. The dispersed mixture enters the upper surface of the guide plate 27. The vibration motor 28 at the bottom of the guide plate 27, in conjunction with the spring rod 26, causes the mixture on the upper surface of the guide plate 27 to enter the upper surface of the screening disc 31. After the mixture enters the upper surface of the screening disc 31, the rotary motor 33 drives the scraper 34 to rotate. When the scraper 34 rotates, it pushes the mixture on the upper surface of the screening disc 31 against the upper wall of the screen 35. The fine sand in the mixture falls through the screen 35 into the interior of the screening disc 31, while the remaining ingredients and large sand are affected by centrifugal force and move along the inner wall of the screening disc 31 into the sorting cylinder 41. Because the inner diameter of the sorting cylinder 41 is small, only a small amount of food and sand can enter it at a time. The remaining mixture is screened repeatedly. When the food and large sand fall along the inner wall of the sorting cylinder 41, X-rays are emitted by the X-ray emitter 43 to irradiate the food and sand, and the reflected light is received by the X-ray receiver 44. Since the food and sand have different absorption properties for X-rays, the food and sand can be sorted by the intensity of the reflected X-rays. The main control board 48 analyzes the reflected signal. When food is identified as passing through, an electrical signal is sent to the air pump 46. After receiving the electrical signal, the air pump 46 pumps air into the nozzle 45. The nozzle 45 sprays high-pressure gas, which causes the food to enter the upper surface of the belt conveyor 10 through the discharge hole 47, while the sand enters the bottom of the sorting cylinder 41.

[0031] In an optional embodiment, the dispersing mechanism 20 includes a fixed frame 21 fixedly installed on one side of the connecting rod 2 13. A hopper 22 is fixedly installed on the upper surface of the fixed frame 21. A dispersing roller 23 is rotatably connected inside the hopper 22. A dispersing motor 24 is fixedly installed on one side of the hopper 22. A transmission belt is provided between the dispersing motor 24 and one side of the dispersing roller 23. The dispersing motor 24 drives the dispersing roller 23 to rotate, thereby dispersing the food and sand, and preventing the sand from embedding into the outer wall of the food and affecting the sorting results.

[0032] In one optional embodiment, multiple side rods 25 are welded to both the left and right sides of the fixing frame 21. Spring rods 26 are fixedly installed at the bottom of the multiple side rods 25. Guide plates 27 are fixedly installed at the bottom of the multiple spring rods 26. Vibration motors 28 are fixedly installed at the bottom of the guide plates 27. The guide plates 27 are inclined and their lowest end is located above the left side of the primary screening mechanism 30. The dispersed mixture enters the upper surface of the guide plates 27. The vibration motors 28 at the bottom of the guide plates 27, in conjunction with the spring rods 26, allow the mixture to enter the upper surface of the screening disc 31 on the one hand, and prevent the mixture from adhering to the upper wall of the guide plates 27 on the other hand.

[0033] In an optional embodiment, the primary screening mechanism 30 includes a screening disc 31 fixedly installed on one side of the connecting rod 12. A base plate 32 is fixedly installed at the bottom of the screening disc 31 by bolts. An integral mounting platform 36 is provided in the middle of the base plate 32. A rotary motor 33 is fixedly installed inside the mounting platform 36. A scraper 34 is fixedly installed at the end of the output shaft of the rotary motor 33. A screen 35 is fixedly installed between the upper end of the mounting platform 36 and the inner wall of the screening disc 31. When the mixture enters the upper surface of the screening disc 31, the rotary motor 33 drives the scraper 34 to rotate. When the scraper 34 rotates, it pushes the mixture on the upper surface of the screening disc 31 onto the upper wall of the screen 35. Fine sand and gravel in the mixture fall into the interior of the screening disc 31 through the screen 35, thereby reducing the scope of equipment inspection. Fine sand and gravel can be processed by removing the base plate 32.

[0034] In one optional embodiment, the upper surface of the screen 35 is provided with a through hole that is compatible with the sorting cylinder 41 on the side close to the inner wall of the screening plate 31, and the upper end of the sorting cylinder 41 is fixedly installed inside the through hole, so that the food can enter the sorting cylinder 41 through the through hole.

[0035] In an optional embodiment, the lower outer wall of the sorting cylinder 41 is provided with an external thread, and the sorting cylinder 41 is threadedly connected to an end cap 49 through the external thread. By unscrewing the end cap 49, the sand and gravel inside the sorting cylinder 41 are processed.

[0036] In an optional implementation, the control motherboard 48 integrates a battery and is electrically connected to the dispersion motor 24, vibration motor 28, rotary motor 33, X-ray transmitter 43, X-ray receiver 44, and air pump 46. The control motherboard 48 controls the start and stop of the dispersion motor 24, vibration motor 28, rotary motor 33, X-ray transmitter 43, and X-ray receiver 44 to achieve automatic sorting.

[0037] In one alternative embodiment, a protective window is fixedly installed on the outer wall of the protective shell 42 near the X-ray emitter 43, and the X-ray emitter 43 is protected through the protective window during the sorting of food and sand.
