Description

Technical Field

[0001] This utility model relates to the field of fruit sorting technology, and in particular to an olive fruit sorting device. Background Technology

[0002] As an important oil crop and processing raw material, the quality of olive fruit is directly related to the subsequent oil extraction efficiency and product flavor. Due to the variety of olive varieties and the difference in the maturity of fruits from the same plant, there are significant differences in fruit size. Therefore, grading and sorting is a key pre-processing step in the olive processing flow. Fruits of different sizes need to be separated to adapt to the targeted processing technology, while avoiding reduced processing efficiency or uneven product quality caused by mixed sizes. A search revealed a Chinese patent with publication number CN217528289U, which provides a fruit sorting device. This device uses a cleaning mechanism that combines a brush roller with a fan-shaped nozzle to spray water onto the fruit while simultaneously scrubbing its surface. An electric telescopic rod drives the fan-shaped nozzle to oscillate, increasing the spray area and improving the scrubbing effect. However, during use, it was found that the sorting aperture of the sieve cylinder is often fixed, or requires disassembly and replacement for adjustment. This is cumbersome and time-consuming, making it difficult to quickly adapt to the size differences of different batches and varieties of olives. This often results in small and large fruits falling together, leading to insufficient sorting accuracy and affecting the sorting effect, which in turn impacts the quality of subsequent processing.

Detailed Implementation

[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0023] like Figure 1-5 As shown, this embodiment provides an olive fruit sorting device, including a sorting frame 100. Two sorting frames 100 are provided, and two connecting blocks 101 are fixedly connected between the two sorting frames 100. A through groove 102 is opened at the upper end of the sorting frame 100. Multiple sorting rollers 103 are provided between the two sorting frames 100. Two rotating shafts 104 are fixedly connected to both ends of the sorting rollers 103 respectively. The outer peripheral wall of the rotating shaft 104 is slidably connected to the inner wall of the through groove 102. A positioning component 200 is installed at the outer end of the rotating shaft 104. The positioning component 200 includes a limiting sleeve 201. A limiting ring 105 is sleeved on the outer wall of the rotating shaft 104. The limiting sleeve 201 is rotatably connected to the limiting ring 105. Two lifting blocks 202 are fixedly connected to the bottom surface of the limiting sleeve 201. The sorting rack 100 is fixedly connected to the outer wall of a spacing component 300. The spacing component 300 includes an adjusting block 301. The top surface of the adjusting block 301 is provided with a sliding groove 302. Multiple slots 303 are connected to both sides of the sliding groove 302. The lifting block 202 is slidably connected to the sliding groove 302. The bottom surfaces of both ends of the limiting sleeve 201 are respectively engaged with the slots 303.

[0024] A worm gear 106 is sleeved on the outer peripheral wall of the rotating shaft 104. A worm 107 is provided on the outer side of the sorting rack 100. Multiple worm gears 106 are respectively meshed with the worm 107. Two movable blocks 108 are rotatably connected to both ends of the worm 107. Two limit blocks 109 are provided on the upper end of the worm 107. The limit blocks 109 are fixedly connected to the upper end of the sorting rack 100. Two movable rods 110 are slidably connected to both ends of the limit blocks 109. The bottom surface of the movable rods 110 is fixedly connected to the top surface of the movable blocks 108. Two first cylinders 111 are installed on both ends of the limit blocks 109. The piston rod of the first cylinder 111 passes through the limit block 109 and is fixedly connected to the top surface of the movable block 108. When the piston rod of the first cylinder 111 extends, it drives the movable block 108 and the worm 107 to move downward, so that the worm 107 disengages from the worm gear 106, reducing tooth surface interference or wear during the adjustment process and ensuring smooth spacing adjustment.

[0025] A fixing block 206 is fixedly connected to the top surface of the limiting sleeve 201. The outer wall of the fixing block 206 is slidably connected to the outer wall of the sorting rack 100 and the inner wall of the limiting block 109. A slot 207 is provided on the top surface of the fixing block 206. The insert block 406 is inserted into the slot 207 of the fixing block 206, so that the fixing block 206 slides upward along the limiting block 109 and drives the limiting sleeve 201 to move synchronously, so that the limiting sleeve 201 is separated from the slot 303.

[0026] One of the movable blocks 108 has a first servo motor 112 installed on its outer wall. The output shaft of the first servo motor 112 is coaxially connected to the worm gear 107. The output shaft of the first servo motor 112 drives the worm gear 107 to rotate. The worm gear 107 drives multiple worm wheels 106 to rotate synchronously through meshing transmission, thereby driving all sorting rollers 103 to rotate at a uniform speed in the same direction, providing a continuous forward driving force for the olive fruits.

[0027] A disc 203 is fixed to the bottom surface of the lifting block 202, and a spring 204 is fixedly connected to the top surface of the disc 203. The spring 204 is sleeved on the lower outer wall of the lifting block 202. A circular block 205 is slidably connected to the lifting block 202. The top surface of the spring 204 abuts against the bottom surface of the circular block 205, and the top surface of the circular block 205 abuts against the bottom surface of the adjusting block 301. When the bottom surfaces of both ends of the limiting sleeve 201 are aligned with the target slot 303, the insert block 406 separates from the slot 207 and retracts to the initial position. The spring 204 elastically resets, pushing the circular block 205 upward, so that the limiting sleeve 201 is stably inserted into the slot 303, thereby achieving the positioning and locking of the sorting roller 103.

[0028] One of the sorting racks 100 has a drive assembly 400 on its top surface. The drive assembly 400 includes a drive block 401. Two T-shaped blocks 402 are slidably connected to both ends of the drive block 401. The bottom surface of the T-shaped blocks 402 is fixedly connected to the top surface of the sorting rack 100. A lead screw 403 is installed on the upper end of one of the T-shaped blocks 402. One end of the drive block 401 is threadedly connected to the lead screw 403. A second servo motor 404 is coaxially connected to one end of the lead screw 403. The second servo motor 404 is installed on one of the sorting racks 100. The second servo motor 404 continues to drive the lead screw 403 to rotate, causing the fixed block 206, the limit sleeve 201, and the lifting block 202 to move synchronously along the slide 302.

[0029] Two second cylinders 405 are symmetrically mounted on the top surface of the drive block 401. An insert block 406 is fixedly connected to the piston rod of the second cylinder 405. The bottom surface of the insert block 406 is slidably connected to a limit post 407. The bottom surfaces of the two limit posts 407 are fixedly connected to the top surface of the drive block 401 respectively. The insert block 406 is inserted into the slot 207. When the piston rod of the second cylinder 405 extends, it drives the insert block 406 to slide along the limit post 407. The insert block 406 is inserted into the slot 207 of the fixed block 206.

[0030] Working principle: The sorting roller 103 is slidably connected to the through groove 102 of the sorting frame 100 through the rotating shafts 104 at both ends. The limiting sleeve 201 at the outer end of the rotating shaft 104 forms a sliding fit with the sliding groove 302 of the adjusting block 301 through the lifting block 202. By moving the lifting block 202 along the sliding groove 302, the limiting sleeve 201 and the connected rotating shaft 104 and sorting roller 103 move synchronously. When the sorting roller 103 moves to the target spacing position, the bottom surfaces of both ends of the limiting sleeve 201 are engaged in the corresponding slots 303 on both sides of the sliding groove 302. The position of the sorting roller 103 is locked through the engagement. By repeating the above operation, the spacing between multiple sorting rollers 103 can be adjusted in sequence to form a sorting channel distributed according to the size gradient, which improves the spacing adjustment efficiency of the sorting roller 103. The olive fruits to be sorted are placed above multiple sorting rollers 103. Since the sorting rollers 103 have a gradient spacing from small to large, under the support of their own weight and the sorting rollers 103, the fruits smaller than the corresponding spacing of the sorting rollers 103 will fall through the gap to complete the grading, while the larger fruits will continue to move along the sorting rollers 103 to the subsequent channels with larger spacing. In the end, the fruits of different sizes are separated step by step, which can adapt to the size differences of different varieties and batches of olive fruits, reduce the mixing of small and large fruits, improve the sorting accuracy and sorting effect, and ensure the quality of subsequent processing. The output shaft of the second servo motor 404 drives the lead screw 403 to rotate, causing the drive block 401 to slide horizontally along the T-block 402 to the fixed block 206 corresponding to the target sorting roller 103; then the piston rod of the second cylinder 405 extends, causing the insertion block 406 to slide along the limiting post 407, and the insertion block 406 to insert into the slot 207 of the fixed block 206, causing the fixed block 206 to slide upward along the limiting block 109, and causing the limiting sleeve 201 to move synchronously, so that the limiting sleeve 201 separates from the slot 303; Then, the second servo motor 404 continues to drive the lead screw 403 to rotate, causing the fixed block 206, the limiting sleeve 201, and the lifting block 202 to move synchronously along the slide 302. During the movement, the round block 205 is squeezed by the bottom surface of the adjusting block 301, compressing the spring 204. When the bottom surfaces of both ends of the limiting sleeve 201 are aligned with the target slot 303, the piston rod of the second cylinder 405 retracts, the insert block 406 separates from the slot 207 and returns to the initial position, the spring 204 elastically resets, and pushes the round block 205 upward, so that the limiting sleeve 201 is stably inserted into the slot 303, realizing the positioning and locking of the sorting roller 103. Repeat the above steps, and adjust each fixed block 206 in sequence through the drive component 400 to complete the gradient spacing adjustment of multiple sorting rollers 103, improving the adjustment efficiency. Before the sorting operation, the piston rod of the first cylinder 111 retracts, driving the movable block 108 to move vertically downward along the movable rod 110, so that the worm 107 meshes with each worm wheel 106; the output shaft of the first servo motor 112 drives the worm 107 to rotate, and the worm 107 drives multiple worm wheels 106 to rotate synchronously through meshing transmission, thereby driving all sorting rollers 103 to rotate at a uniform speed in the same direction, providing a continuous forward driving force for the olive fruits; when it is necessary to adjust the spacing of the sorting rollers 103 again, the piston rod of the first cylinder 111 extends, driving the movable block 108 and the worm 107 to move downward, so that the worm 107 disengages from the worm wheels 106, reducing tooth surface interference or wear during the adjustment process, and ensuring smooth spacing adjustment; After adjusting the gradient spacing, the worm gear 107 and worm wheel 106 re-mesh, and the sorting roller 103 rotates synchronously. The olive fruits to be sorted are placed above the sorting roller 103. The fruits adhere to the spacing under their own gravity and are smoothly conveyed forward under the rotational driving force of the sorting roller 103. Fruits smaller than the current spacing of the sorting roller 103 fall through the gap to complete the grading, while larger fruits move to the subsequent larger spacing channel as the sorting roller 103 rotates. The external collection box is placed under the corresponding two sorting rollers 103 to collect the sorted fruits, thus realizing the sorting and collection of fruits of different sizes.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
