Description

Technical Field

[0001] This utility model relates to the field of agricultural equipment technology, and in particular, to a spherical fruit cleaning device. Background Technology

[0002] In modern agricultural production, the sorting of spherical fruits is a crucial step in improving fruit classification. Spherical fruits, such as camellia oleifera and macadamia nuts, require precise sorting based on their diameter due to their regular shape and varying sizes, in order to meet different processing needs and market standards. Existing sorting equipment, when processing spherical fruits, may encounter blockages as the fruits become stuck in the sorting holes due to their near-spherical shape. This blockage reduces sorting efficiency and can even cause the entire sorting equipment to shut down. 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 effectiveness if cleaning is not done promptly.

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

[0037] The frame 100 is provided with an upper open receiving cavity 110, and the front wall of the frame 100 is provided with a feed inlet 120, and a feed hopper 121 is installed at the feed inlet 120.

[0038] The sorting cylinder 200 is rotatably mounted within the receiving cavity 110 of the frame 100 along its own axis. One end of the sorting cylinder 200 is open corresponding to the feed inlet 120 to receive raw materials entering from the feed inlet 120. The peripheral wall of the sorting cylinder 200 is provided with sorting holes 210. Multiple sets of sorting holes 210 are arranged along the axial direction. The sorting holes 210 in the same set are arranged in a ring and have the same diameter. The diameter of the sorting holes 210 in different sets gradually increases in the direction away from the feed inlet 120, thereby realizing step-by-step sorting.

[0039] A rotary drive mechanism 300 drives the sorting cylinder 200 to rotate. A cleaning roller 400 is rotatably mounted within the receiving cavity 110 of the frame 100 along its own axis, with its axis parallel and spaced apart from the axis of the sorting cylinder 200. The cleaning roller 400 is located on the outer periphery of the sorting cylinder 200 so that spherical fruits stuck in the sorting holes 210 can be pushed back into the sorting cylinder 200 by the cleaning roller 400. It is understood that the spherical fruits stuck in the sorting holes 210 will partially protrude from the sorting holes 210. The cleaning roller 400 will then contact the protruding part of the spherical fruit and push it back into the sorting cylinder 200. It is understood that the peripheral wall of the cleaning roller 400 is adjacent to the peripheral wall of the sorting cylinder 200; adjacent means close to each other. The cleaning roller 400 and the outer peripheral wall of the sorting cylinder 200 are fitted together with a small gap, for example, less than 1 cm.

[0040] This utility model provides a spherical fruit cleaning device. By setting a cleaning roller 400, it can automatically push the spherical fruits stuck in the sorting holes 210 into the sorting cylinder 200, thereby avoiding the problem of reduced sorting efficiency and equipment downtime caused by fruit blockage. Due to the automatic cleaning function of the cleaning roller 400, the need for manual intervention is reduced, allowing the sorting process to be carried out continuously and significantly improving sorting efficiency. The automated cleaning roller 400 reduces the frequency and intensity of manual cleaning, thereby reducing the labor costs caused by manual cleaning. Moreover, when the sorting cylinder 200 rotates with the spherical fruits stuck in the sorting holes 210 and passes through the cleaning roller 400, the cleaning roller 400 can rotate around its own axis, avoiding sliding friction and turning sliding friction into rolling friction. This can effectively reduce the frictional resistance when the spherical fruits come into contact with the cleaning roller 400, reduce wear on the surface of the spherical fruits, and reduce damage to the surface of the spherical fruits.

[0041] Reference Figure 1 In some embodiments of this utility model, the cleaning rollers 400 are symmetrically arranged on the left and right sides of the sorting cylinder 200, thereby achieving multi-position cleaning and improving cleaning efficiency and effect.

[0042] Reference Figure 1 and Figure 2 In some embodiments of this utility model, the rotary drive mechanism 300 is a motor, and a rotating shaft 220 is installed at the center of the sorting cylinder 200. The rotating shaft 220 extends through the rear side wall of the frame 100, and its front and rear ends are rotatably mounted on the front and rear side walls of the frame 100, respectively. The rotary drive mechanism 300 is a rotary motor, and the output shaft of the rotary motor extends through the rear side wall of the frame 100 and is connected to the rotating shaft 220 for transmission. The output shaft and the rotating shaft 220 can be driven by a chain or belt. The output shaft can be connected to a drive wheel, and a transmission wheel can be installed on the rotating shaft 220. The drive wheel and the transmission wheel are driven by a chain or belt.

[0043] Reference Figures 1 to 3In a further embodiment of this utility model, the frame 100 includes end plates 130 spaced apart front and rear, and vertical plates 140 spaced apart left and right are sandwiched between the two end plates 130. The bottom of the vertical plates 140 on the left and right sides is provided with inclined plates 150 that approach each other. The bottom of the inclined plates 150 is spaced apart to form a discharge port 151 for the output of spherical fruits. The material passing through the sorting hole 210 is finally output from the discharge port 151. A conveyor belt is provided at the bottom of the discharge port 151 to transport the sorted material.

[0044] Reference Figures 1 to 3 In a further embodiment of this utility model, the rotary motor is installed on the rear end plate 130 and located outside the inclined plate 150. The extra space left by the inward tilt of the inclined plate 150 is used to install the rotary motor, thereby maximizing space utilization and reducing the overall structure volume and footprint.

[0045] Reference Figures 1 to 3 In a further embodiment of this utility model, first bearings 160 are installed on the front and rear end plates 130 to be sleeved on both ends of the rotating shaft 220. Specifically, bearing seats are provided on the front and rear end plates 130 to install the first bearings 160. The first bearings 160 are used to reduce rotational friction.

[0046] Reference Figure 2 In a further embodiment of this utility model, a rotating shaft 220 is installed at the center of the sorting cylinder 200. The rotating shaft 220 is connected to the inner wall of the sorting cylinder 200 through radial rods 230. Multiple radial rods 230 are distributed around the rotating shaft 220 at intervals, thereby realizing the connection between the sorting cylinder 200 and the rotating shaft 220. The interval distribution of the radial rods 230 does not affect the feeding of materials.

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

[0048] Reference Figure 4 and Figure 5 In a further embodiment of this utility model, the cleaning roller 400 is elastically and movably mounted on the frame 100. The cleaning roller 400 is subjected to an elastic force to drive it to approach the sorting cylinder 200, thereby realizing the flexible installation of the cleaning roller 400, avoiding rigid contact between it and the spherical fruit, and reducing damage to the spherical fruit.

[0049] Reference Figures 5 to 7In a further embodiment of this utility model, a mounting plate 500 is provided on the frame 100. Specifically, the mounting plate 500 and the frame 100 are provided with corresponding holes for connection and fixation by fasteners. The mounting plate 500 is provided with a threaded hole 510, and an adjusting sleeve 520 is threadedly connected to the threaded hole 510. The adjusting sleeve 520 is provided with a movable hole 521 at its center. A movable rod 530 is movably inserted through the movable hole 521. A bearing sleeve 540 is provided at one end of the movable rod 530 near the sorting cylinder 200. The bearing sleeve 540 is provided with a bearing hole 541. The cleaning roller 400 is provided with journals 410 at both ends. The journals 410 are embedded in the bearing holes 541 and are fitted with second bearings 411. A threaded shaft 531 is provided at one end of the movable rod 530 away from the bearing sleeve 540, which extends out of 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 disengaging from the adjusting sleeve 520. A compression spring 533 is fitted onto the movable rod 530. The two ends of the compression spring 533 abut against the adjusting sleeve 520 and the bearing sleeve 540, respectively, thus enabling the elastic installation of the mounting plate 500. The position of the adjusting sleeve 520 is adjusted by rotating it in the threaded hole 510, thereby adjusting the distance between the cleaning roller 400 and the sorting cylinder. The compression degree of the compression spring 533 can be adjusted by tightening the nut 532, thus adjusting the magnitude of the elastic force. Although tightening the nut 532 changes the position of the cleaning roller 400, the combined adjustment of the nut 532 and the adjusting sleeve 520 allows for a compound adjustment of the cleaning roller 400's position. This allows for adjusting the compression degree of the compression spring 533 without changing the position of the cleaning roller 400. Furthermore, the adjustment of the nut 532 and the adjusting sleeve 520 can expand the adjustment range of the cleaning roller 400's position.

[0050] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
