This blockage phenomenon will reduce the sorting efficiency and may even cause the entire sorting equipment to shut down. In order to solve this problem, regular manual cleaning is usually required, which not only increases labor costs, but may also lead to a decrease in sorting efficiency and effect due to untimely cleaning.

[0036] Please refer to Figure 1 and Figure 2 A spherical fruit cleaning device in a preferred embodiment of the present invention includes a frame 100, a sorting drum 200, a rotary drive mechanism 300 and a cleaning roller 400.

[0037] The frame 100 is provided with a receiving chamber 110 with an upper opening, and a front end wall of the frame 100 is provided with a feed port 120 , at which a feed hopper 121 is installed.

[0038] The sorting barrel 200 is rotatably installed in the accommodating cavity 110 of the frame 100 along its own axis. The sorting barrel 200 is opened at one end corresponding to the feed port 120 to receive the raw materials entering from the feed port 120. The circumferential wall of the sorting barrel 200 is provided with sorting holes 210, and the sorting holes 210 are arranged in multiple groups along the axial direction. The sorting holes 210 in the same group are arranged in a surrounding manner and have the same diameter. The diameters of the sorting holes 210 in different groups gradually increase in the direction away from the feed port 120, thereby realizing step-by-step sorting.

[0039] The rotary drive mechanism 300 is used to drive the sorting drum 200 to rotate. The cleaning roller 400 is rotatably installed in the accommodating cavity 110 of the frame 100 along its own axis, and the axis of the cleaning roller 400 is arranged parallel to the axis of the sorting drum 200 and spaced apart. The cleaning roller 400 is located at the outer periphery of the sorting drum 200 so that the spherical fruit stuck in the sorting hole 210 can be pushed into the sorting drum 200 by the cleaning roller 400. It can be understood that the spherical fruit stuck in the sorting hole 210 will partially protrude from the sorting hole 210. The cleaning roller 400 will contact the protruding part of the spherical fruit and push it back into the sorting drum 200. It can be understood that the peripheral wall of the cleaning roller 400 is arranged adjacent to the peripheral wall of the sorting drum 200, which means that they are arranged close to each other. The cleaning roller 400 and the peripheral wall of the sorting drum 200 are set in a close fit, with a small gap, for example, a gap of less than 1 cm.

[0040] The present invention provides a spherical fruit cleaning device, which can automatically push the spherical fruit stuck in the sorting hole 210 into the sorting cylinder 200 by setting a cleaning roller 400, thereby avoiding the problem of reduced sorting efficiency and equipment shutdown caused by fruit blockage; due to the automatic cleaning function of the cleaning roller 400, the need for manual intervention is reduced, so that the sorting process can be carried out continuously, and the sorting efficiency is significantly improved. The automated cleaning roller 400 reduces the frequency and intensity of manual cleaning, thereby reducing the labor cost generated by manual cleaning; and when the sorting cylinder 200 rotates with the spherical fruit stuck in the sorting hole 210 and passes through the cleaning roller 400, since the cleaning roller 400 can rotate around its own axis, sliding friction is avoided, and sliding friction is converted into rolling friction, which can effectively reduce the friction resistance when the spherical fruit contacts the cleaning roller 400, reduce the wear on the surface of the spherical fruit, and reduce the damage to the surface of the spherical fruit.

[0041] Reference Figure 1 In some embodiments of the present invention, the cleaning rollers 400 are symmetrically arranged on the left and right sides of the sorting drum 200, so as to achieve multi-position cleaning and improve the cleaning efficiency and effect.

The bottoms of the vertical plates 140 on the left and right sides are provided with inclined plates 150 close to each other. The bottoms of the inclined plates 150 are spaced apart to form a discharge port 151 for outputting the spherical fruits. The materials passing through the sorting holes 210 are finally output from the discharge port 151. A conveyor belt will be provided at the bottom of the discharge port 151 to transport the sorted materials.

[0044] Reference Figures 1 to 3 In a further embodiment of the present invention, the rotating motor is installed on the rear end plate 130 and is located outside the inclined plate 150. The rotating motor is installed using the extra space left by the inclined plate 150 tilting inward, thereby maximizing space utilization and reducing the volume and floor space of the overall structure.

There are multiple radial rods 230 distributed around the rotating shaft 220 at intervals, thereby realizing the connection between the sorting drum 200 and the rotating shaft 220, and the interval distribution of the radial rods 230 does not affect the feeding of the material.

[0047] In a further embodiment of the present invention, the peripheral wall of the cleaning roller 400 is made of rubber or silicone material, thereby reducing the damage to the spherical fruit by the cleaning roller 400. Of course, the cleaning roller 400 can also be made of metal material, and the outer periphery of the cleaning roller 400 is sleeved with a flexible soft sleeve.

A threaded shaft 531 is provided at one end of the movable rod 530 away from the bearing sleeve 540, which penetrates the movable hole 521. A nut 532 with a profile larger than the movable hole 521 is connected to the threaded shaft 531 to prevent the movable rod 530 from detaching from the adjusting screw sleeve 520. The movable rod 530 is sleeved with a compression spring 533, and the two ends of the compression spring 533 are respectively against the adjusting screw sleeve 520 and the bearing sleeve 540, so that the elastic installation of the mounting plate 500 is realized by the compression spring 533. The position adjustment is realized by rotating the adjusting screw sleeve 520 in the threaded hole 510, so as to adjust the distance between the cleaning roller 400 and the sorting drum, and the compression degree of the compression spring 533 can be adjusted by screwing the nut 532, so as to adjust the size of the elastic force; although screwing the nut 532 will change the position of the cleaning roller 400, screwing the nut 532 and cooperating with the position adjustment of the adjusting screw sleeve 520 can adjust the position of the cleaning roller 400 in combination, and the position of the cleaning roller 400 can be adjusted without changing the position of the cleaning roller 400 when the compression degree of the compression spring 533 is adjusted.
