[0021] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are also within the scope of protection of this application.
[0022] like Figures 1-4 As shown, one embodiment of this application provides a potato sorting device, including a sorting frame 1. The lower end of the sorting frame 1 is provided with a transversely penetrating discharge port 2 and a discharge port 3 along the conveying direction. The sorting frame 1 is symmetrically provided with chains 4 on both sides along the conveying direction. The chains 4 are arranged in a ring and independently circulate around the two ends of the discharge port 2 and the discharge port 3. The four corners of the ring chain 4 are supported and engaged by sprockets 7. The chains 4 at both ends of the discharge port 2 and the discharge port 3 are connected by rollers to form a grid 5 and a grid 6 respectively. The spacing of the grid 6 is greater than the spacing of the grid 5. The two adjacent sprockets 7 between the grid 5 and the grid 6 are connected by a transmission chain 8.
[0023] In operation, potatoes are fed to the front end of the sorting rack 1 via a feeder. A motor drives one of the sprockets 7 to rotate, causing the chain 4 to rotate cyclically in the conveying direction. This, in turn, causes the grids 5 and 6 to rotate cyclically, pushing the potatoes forward along the conveying direction on the rollers. During this movement, smaller potatoes fall between the wider-spaced rollers of grid 5, while larger potatoes fall between the narrower-spaced rollers of grid 6. The largest potatoes are transported to the end of the sorting rack 1 and fall off.
[0024] In this embodiment, the potatoes are pushed along the conveying direction of the sorting frame 1, and are sorted by the grating one 5 and the grating two 6. The spacing of the grating two 6 is greater than that of the grating one 5, and the potatoes with a size smaller than the spacing between the rollers are sorted and dropped from the corresponding rollers one by one, and the potatoes that are not sorted drop from the end of the sorting frame 1. The independently circulating grating one 5 and the grating two 6 have fixed spacing, which can more accurately sort the potatoes, and the overall circulation of the grating formed by the rollers can smoothly push the potatoes forward, without the phenomenon of slipping, and the efficiency is higher than that of the existing rollers rolling around the axis to push the potatoes. When the spacing between the rollers needs to be adjusted, different diameter rollers can be replaced.
[0025] In a possible implementation, the two ends of the roller are respectively sleeved with a gear 9, and the sorting frame 1 at the lower end of the gear 9 is fixed with a rack 10 engaged with the gear 9.
[0026] The gear 9 is engaged with the rack 10 fixed at the lower end, and in the process of circulating rotation, the roller can rotate around the axis in the moving direction through the engagement of the gear 9. The circulation and self-rotation can drive the potatoes to roll during sorting, prevent the potatoes from being jammed, and improve the sorting effect.
[0027] In a possible implementation, either side of the material falling port one 2 and the material falling port two 3 can be laterally inserted into a conveyor 11 for receiving materials, and the end of the sorting frame 1 in the conveying direction is fixed with a material guide groove 12, and the conveyor 11 is arranged below the material guide groove 12.
[0028] The potatoes screened by the grating one 5 and the grating two 6 fall on the conveyor 11 inserted into the material falling port one 2 and the material falling port two 3 respectively, and the potatoes falling from the end of the sorting frame 1 fall on the conveyor 11 arranged below the material guide groove 12. After being output by the conveyor 11, the potatoes are bagged.
[0029] In a possible implementation, the conveyor 11 is provided with a material receiving port for fixing a packaging bag at the end of the conveying direction, a partition plate 13 is fixed in the middle of the material receiving port, and a material guide plate 14 capable of switching the material guide direction to the two sides of the partition plate 13 is hinged to one end of the conveying belt.
[0030] The partition plate 13 divides the material receiving port into two, and packaging bags can be fixed at the lower ends of the two material receiving ports respectively, and the material guide direction can be switched by rotating the material guide plate 14, so that the potatoes are alternately bagged by switching the material guide direction, and the efficiency of bagging is improved.
[0031] In one possible implementation, the sorting frame 1 is rotatably connected to a plurality of desludge rollers 15 at the front end in the conveying direction, and two adjacent desludge rollers 15 are connected by a roller chain drive. The end desludge roller 15 is connected to the sprocket 7 by a drive chain 8. A mud trough 16 is fixed below the desludge roller 15.
[0032] After the potatoes are conveyed to the front end of the sorting frame 1 by the feeder, they fall onto the mud removal roller 15. The rotating mud removal roller 15 can make the potatoes tumble during the movement, and the tumbling and friction can remove the mud from the potatoes.
[0033] like Figure 5 As shown, in one possible implementation, a plurality of rubber sheets are radially fixed to the outer wall of the mud removal roller 15.
[0034] When the rotating descaling roller 15 tumbles the potatoes, the mud on the potatoes is further removed by the agitation of the rubber sheet.
[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
