Abstract
Description
Technical Field
[0001] This utility model relates to the field of olive fruit screening technology, specifically a multi-stage olive fruit screening machine. Background Technology
[0002] Olives are the fruit of the olive tree, an oilseed crop belonging to the Oleaceae family and the Oleaceae genus. They are mainly used for oil extraction. After harvesting, olives need to be sorted according to factors such as fruit size and plumpness to produce different grades of products to meet different needs.
[0003] For example, patent CN218797275U discloses a fruit sorting mechanism for olives after harvesting. It includes a sorting box and a drive assembly. A drive motor rotates a rotating rod, which in turn drives a cam to push a base plate upwards. This causes the base plate to push a mounting rod, a connecting rod, and two screens upwards. With the help of springs, the two screens move downwards, causing them to vibrate and thus accelerating the sorting process. However, this example only uses two screens to sort olives. For a group of olives with significant size and quality variations, this simple two-stage sorting method can easily lead to insufficient sorting precision. Fruits that are similar in size but different in quality may not be accurately distinguished, resulting in a less refined fruit grade and failing to meet the market demand for high-quality, precisely graded olives.
[0004] To address the aforementioned issues, there is an urgent need for innovative design based on the existing multi-stage screening machine for olive fruits. Utility Model Content
[0005] The purpose of this invention is to provide a multi-stage screening machine for olive fruits, in order to solve the problem mentioned in the background art that screening olive fruits using only two screens is prone to insufficient screening accuracy for groups of olive fruits with large size differences and uneven quality.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-stage screening machine for olive fruits, comprising a base, a screening seat slidably connected to the top of the base via a support column, a drive platform mounted on one side of the base, and a feed box mounted on one side of the top of the drive platform; the screening seat has multiple conical rods inside, three sets of first screen plates are mounted at the bottom of the screening seat, and a second screen plate is mounted at the bottom of the first screen plates, the aperture of the first screen plates is larger than the aperture of the second screen plates, and the apertures of the three sets of first screen plates are arranged from small to large; the drive platform is provided with a reciprocating mechanism for reciprocating movement of the screening seat.
[0007] Furthermore, the reciprocating mechanism includes a drive motor, which is fixedly connected to the bottom wall of the drive platform. A rotating column is mounted on the top of the drive platform via a bracket. The outer wall of the rotating column and the output end of the drive motor are both fixedly connected to pulleys, and a belt is provided between the two pulleys.
[0008] Furthermore, an eccentric wheel is fixedly connected to one end of the rotating column, and a rotating seat is installed on the side of the screening seat near the drive table. A connecting rod is rotatably connected to the eccentric end of the eccentric wheel, and one end of the connecting rod is rotatably connected to the inside of the rotating seat.
[0009] Furthermore, the rotating column is provided with an auxiliary mechanism to assist in material screening. The auxiliary mechanism includes a rotating roller, which is rotatably connected to both ends of one side of the screening seat. Synchronous wheels are installed on the outer wall of the rotating column away from the eccentric wheel and on the rotating roller on one side. A synchronous belt is provided between the two synchronous wheels. A sprocket is fixedly connected to one end of each of the two rotating rollers. A chain is provided between the sprockets.
[0010] Furthermore, a push plate is fixedly connected to the chain of the sprocket, a sliding column is installed at one end of the push plate, and an arc-shaped groove is opened on one side of the screening seat, with the sliding column slidably connected inside the arc-shaped groove.
[0011] Furthermore, the diameter of the pulley on the output end of the drive motor is smaller than that of the pulley on the rotating column, and a discharge plate is installed on the side of the screening seat away from the feed box.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] This multi-stage olive fruit screening machine uses a drive motor to rotate a pulley, a rotating column, and an eccentric wheel. The eccentric motion of the eccentric wheel drives a connecting rod, which in turn causes the rotating seat to slide back and forth on the base. This allows the olive fruits to move better on the screen plate, constantly changing their position and distributing them evenly on the screen plate. This significantly improves screening efficiency and ensures that more fruits are effectively screened.
[0014] Furthermore, the fruits first undergo preliminary screening using conical rods. Fruits smaller than the distance between two conical rods fall to the first sieve plate for secondary screening. After the first sieve plate, larger fruits are collected, while smaller fruits continue to fall to the second sieve plate for further screening. Fruits are meticulously classified according to size, resulting in different grades. Compared to single-stage screening, multi-stage screening can more accurately separate fruits of different sizes, meeting diverse market demands, improving the precision and quality of fruit screening, and ensuring that the fruits are thoroughly subdivided.
[0015] Furthermore, the drive motor drives the rotating column to rotate, which in turn drives the rotating roller to rotate via a synchronous pulley and synchronous belt. The rotating roller, in turn, drives the rotating roller on the other side to rotate synchronously via a sprocket and chain, and the push plate on the sprocket moves accordingly. The sliding column at one end of the push plate slides in the arc-shaped groove, and the movement of the push plate can push the olive fruits in the screening seat, so that they can move and be distributed better in the screening seat.

Detailed Implementation
[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Example 1: Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5This utility model provides the following technical solution: a multi-stage screening machine for olive fruits, including a base 1, a screening seat 2 slidably connected to the top of the base 1 via a support column, a drive platform 4 installed on one side of the base 1, and a feed box 3 installed on one side of the top of the drive platform 4; the screening seat 2 has multiple conical rods 6 inside, three sets of first screen plates 7 are installed at the bottom of the screening seat 2, and second screen plates 8 are installed at the bottom of the first screen plates 7. The aperture of the first screen plates 7 is larger than the aperture of the second screen plates 8, and the apertures of the three sets of first screen plates 7 are arranged from small to large; the drive platform 4 is equipped with... A reciprocating mechanism for reciprocating movement of the screening seat 2; the reciprocating mechanism includes a drive motor 5, which is fixedly connected to the inner bottom wall of the drive platform 4. A rotating column 9 is mounted on the top of the drive platform 4 via a bracket. Pulleys 10 are fixedly connected to both the outer wall of the rotating column 9 and the output end of the drive motor 5. A belt is provided between the two pulleys 10. An eccentric wheel 11 is fixedly connected to one end of the rotating column 9. A rotating seat 13 is installed on the side of the screening seat 2 near the drive platform 4. A connecting rod 12 is rotatably connected to the eccentric end of the eccentric wheel 11. One end of the connecting rod 12 is rotatably connected to the inside of the rotating seat 13.
[0025] When using equipment to sort olive fruits, such as Figure 3 As shown, the fruit is first placed inside the feeding box 3, and then falls into the screening seat 2 through the feeding box 3. Then, the drive motor 5 on the bottom wall of the drive platform 4 is activated. Figure 4 and Figure 5 As shown, since the outer wall of the rotating column 9 is also fixedly connected to a pulley 10, and a belt is provided between the two pulleys 10, when the drive motor 5 starts, its output end drives the pulley 10 fixedly connected to it to rotate. The pulley 10 drives the pulley 10 on the rotating column 9 to rotate through the belt, thereby causing the rotating column 9 to rotate. Figure 4 and Figure 5 As shown, since one end of the rotating column 9 is fixedly connected to an eccentric wheel 11, and a rotating seat 13 is installed on the side of the screening seat 2 near the drive platform 4, a connecting rod 12 is rotatably connected to the eccentric end of the eccentric wheel 11, and one end of the connecting rod 12 is rotatably connected to the inside of the rotating seat 13. Therefore, when the rotating column 9 drives the eccentric wheel 11 to rotate, the eccentric movement of the eccentric wheel 11 will drive the connecting rod 12 to rotate on it, and the movement of the connecting rod 12 will drive the rotating seat 13 to move synchronously. Figure 1 and Figure 2As shown, since the screening seat 2 is slidably connected to the base 1, when the rotating seat 13 moves under the drive of the connecting rod 12, it will cause the screening seat 2 to slide back and forth on the base 1. This helps the olive fruits move better on the screening plate, increases the contact opportunity between the fruit and the screening plate, and improves the screening efficiency. After the fruit falls onto the conical rod 6, it passes through different positions of the conical rod 6. When the fruit is smaller than the distance between the two conical rods 6, the fruit will fall into the interior of the first screening plate 7 below the conical rod 6 for secondary screening. The larger fruits that remain on the first screening plate 7 after screening fall from one end of the first screening plate 7 into the interior of the external collection box, while the smaller fruits fall onto the second screening plate 8. After screening by the second screening plate 8, the smallest fruits fall into the interior of the bottom external collection box. The fruits on the second screening plate 8 are also collected by the external collection box, which can ensure that the fruits are finely divided.
[0026] Example 2: Please refer to Figure 1 , Figure 4 , Figure 5 and Figure 6 Based on Embodiment 1, an auxiliary mechanism is also disclosed, the specific structure of which is as follows:
[0027] The auxiliary mechanism includes a rotating roller 15, which is rotatably connected to both ends of one side of the screening seat 2. The outer wall of the rotating column 9 away from the eccentric wheel 11 and the rotating roller 15 on one side are both equipped with synchronous wheels 14. A synchronous belt is provided between the two synchronous wheels 14. A sprocket 16 is fixedly connected to one end of each of the two rotating rollers 15. A chain is provided between the sprockets 16. A push plate 17 is fixedly connected to the chain of the sprocket 16. A sliding column 18 is installed at one end of the push plate 17. An arc-shaped groove 19 is opened on one side of the screening seat 2. The sliding column 18 is slidably connected to the inside of the arc-shaped groove 19. The diameter of the pulley 10 on the output end of the drive motor 5 is smaller than that of the pulley 10 on the rotating column 9. A discharge plate 20 is installed on the side of the screening seat 2 away from the feed box 3.
[0028] When the fruit falls onto the conical rod 6, it may get stuck. Therefore, an auxiliary mechanism is designed to prevent the fruit from getting stuck, such as... Figure 4 and Figure 5 As shown, since synchronous pulleys 14 are installed on both the outer wall of the rotating column 9 away from the eccentric wheel 11 and the rotating roller 15 on one side, and a synchronous belt is provided between the two synchronous pulleys 14, when the drive motor 5 drives the rotating column 9 to rotate through the pulley 10, the rotating column 9 will drive the rotating roller 15 on one side to rotate through the synchronous pulleys 14 and the synchronous belt, as shown. Figure 5 and Figure 6As shown, since one end of each of the two rotating rollers 15 is fixedly connected to a sprocket 16, and a chain is provided between the sprockets 16, when the rotating column 9 drives one side of the rotating roller 15 to rotate, the rotation of one side of the rotating roller 15 will drive the other side of the rotating roller 15 to rotate synchronously through the sprocket 16 and the chain, as shown. Figure 6 As shown, since a push plate 17 is fixedly connected to the chain of sprocket 16, when sprocket 16 rotates, it will drive push plate 17 to move synchronously, as shown. Figure 6 As shown, since a sliding column 18 is installed at one end of the push plate 17, and an arc-shaped groove 19 is provided on one side of the screening seat 2, the sliding column 18 is slidably connected to the inside of the arc-shaped groove 19. Therefore, when the push plate 17 moves, it will drive the sliding column 18 to slide in the arc-shaped groove 19. The movement of the push plate 17 can push the olive fruits in the screening seat 2, so that they can move and distribute better in the screening seat 2, further promoting the screening of the fruits. The side of the screening seat 2 away from the feed box 3 is equipped with a discharge plate 20. After multi-stage screening, the large olive fruits left on the conical rod 6 will be discharged from the screening machine from the discharge plate 20, completing the screening process.
