DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-4The utility model provides a technical solution: a cleaning and sorting device for nut processing, including a cleaning cylinder 1, a servo motor 2, a vertical shaft 3, an inner rotating cylinder 4, a feeding window 5, a guide plate 6, a water supply pipe 7, a first high-pressure nozzle 8, a second high-pressure nozzle 9, a cleaning brush 10, a discharge window 11, a sorting guide plate 12, a first sorting hole 13, a second sorting hole 14, a third sorting hole 15 and a collecting net frame 16. The top of the cleaning cylinder 1 is fixed with a servo motor 2, the bottom of the servo motor 2 is installed with a vertical shaft 3, the bottom end of the vertical shaft 3 is rotatably connected to the bottom of the inner side of the cleaning cylinder 1, and the vertical shaft 3 is fixed on the top of the cleaning cylinder 1. There is an inner rotating cylinder 4, a feeding window 5 is provided on the top surface of the cleaning cylinder 1, a guide plate 6 is fixedly installed on the top of the inner wall of the cleaning cylinder 1, a water supply pipe 7 is fixed on the inner wall of the cleaning cylinder 1 below the guide plate 6, a first high-pressure nozzle 8 and a second high-pressure nozzle 9 are fixedly installed on the bottom end and the inner side of the bottom of the water supply pipe 7 respectively, cleaning bristles 10 are fixedly installed on the middle part of the inner wall of the cleaning cylinder 1 and the outer wall of the inner rotating cylinder 4, a discharge window 11 is provided on one side of the bottom end of the cleaning cylinder 1, the columnar structure at the bottom end of the cleaning cylinder 1 is connected and fixed to the middle part of the top end of the sorting guide plate 12, and a collecting mesh frame 16 is arranged below the sorting guide plate 12.

[0021] In this example, the cleaning bristles 10 on the inner wall of the cleaning cylinder 1 and the vertical part of the outer wall of the inner rotating cylinder 4 are staggered, the top of the inner rotating cylinder 4 is set to a truncated cone shape, the bottom of the inner rotating cylinder 4 is set to a cylindrical shape, and the inner bottom surface of the cleaning cylinder 1 is set to an inclined surface. The above-mentioned structural design enables the inclined surface at the top of the inner rotating cylinder 4 to guide the nuts, and the inner rotating cylinder 4 can use the cleaning bristles 10 to comprehensively clean the surface of the nuts when rotating. At the same time, the inclined surface at the bottom of the cleaning cylinder 1 facilitates the rapid discharge of the nuts.

[0022] The guide plate 6 and the water supply pipe 7 are both arranged in a ring shape, and the front view section of the guide plate 6 is a parallelogram. The above-mentioned structural design enables the guide plate 6 to guide the nuts into the space between the inner side of the cleaning cylinder 1 and the outer side of the inner rotating cylinder 4, and at the same time can shield and protect the water supply pipe 7, the first high-pressure nozzle 8 and the second high-pressure nozzle 9 to prevent the nuts from colliding with the water supply pipe 7, the first high-pressure nozzle 8 and the second high-pressure nozzle 9.

[0023] The first high-pressure nozzle 8 and the second high-pressure nozzle 9 are densely arranged at equal angles at the bottom end and the inner side of the bottom end of the water supply pipe 7. The first high-pressure nozzle 8 is vertically arranged and the second high-pressure nozzle 9 is inclined. The above structural design can comprehensively rinse the nuts.

[0024] The first sorting hole 13, the second sorting hole 14 and the third sorting hole 15 are respectively penetrated through the upper, middle and lower parts of the bottom surface of the sorting guide plate 12. The sorting guide plate 12 is inclined. The above structural design enables the nuts to pass through the first sorting hole 13, the second sorting hole 14 and the third sorting hole 15 for size sorting during the process of rolling downward.

[0025] The hole diameters of the first sorting hole 13, the second sorting hole 14 and the third sorting hole 15 increase successively, and the first sorting hole 13, the second sorting hole 14 and the third sorting hole 15 are densely arranged at equal intervals. The above structural design allows larger nuts to fall sufficiently, and the nuts are not easy to block the first sorting hole 13, the second sorting hole 14 and the third sorting hole 15, thereby ensuring smooth sorting.

[0026] Working principle: When using this device, the nuts to be cleaned and sorted are passed through Figure 2 The nuts are poured into the cleaning cylinder 1 through the feeding window 5 in the inner rotating cylinder 4. The nuts are guided by the guide plate 6 and the top slope of the inner rotating cylinder 4 to move between the inside of the cleaning cylinder 1 and the outside of the inner rotating cylinder 4. At this time, the water supply pipe 7 is supplied with water through the external water pump, and the first high-pressure nozzle 8 and the second high-pressure nozzle 9 spray high-speed water flow to wash the dirt on the surface of the nuts.

[0027] Then the nuts fall into the space between the inner side of the cleaning cylinder 1 and the outer side of the inner rotating cylinder 4, and the servo motor 2 is controlled to drive the inner rotating cylinder 4 to rotate stably through the vertical shaft 3. The cleaning bristles 10 on the side wall of the inner rotating cylinder 4 cooperate with the cleaning bristles 10 on the inner wall of the cleaning cylinder 1 to clean the nuts. The nuts fall along the space between the inner side of the cleaning cylinder 1 and the outer side of the inner rotating cylinder 4, and rotate during the falling process, and are fully cleaned.

[0028] Then the cleaned nuts are discharged into the sorting guide plate 12 along the inner bottom surface of the inclined cleaning cylinder 1 through the discharge window 11, and roll downward along the inclined sorting guide plate 12. The smaller nuts fall through the first sorting hole 13, and the remaining nuts continue to fall. The slightly larger nuts fall through the second sorting hole 14, and the largest nuts continue to roll downward and fall through the third sorting hole 15, and are collected by different collecting frames 16. This is the working principle of the cleaning and sorting device for nut processing.

[0029] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
