Abstract
Description
Technical Field
[0001] This utility model relates to the field of peach production technology, specifically a drum-type peach sorting machine. Background Technology
[0002] Before being sold, hard peaches such as nectarines need to be sorted by size using a sorting machine. Traditional sorting machines usually use a sieve cylinder for sieving. When the fruit passes through the sieve cylinder, it falls directly onto a guide plate and then rolls down the guide plate into a collection box. However, this sorting method has the following problems:
[0003] Because the existing guide plate and collection frame design cannot effectively buffer the impact on the fruit, when the fruit passes through the screen cylinder and rolls onto the guide plate, it will be subjected to a certain amount of falling and rolling force, which may cause damage to the surface of the fruit, affecting the appearance and quality of the fruit, reducing the market value and storage life of the fruit.
[0004] Therefore, in order to solve the problem that existing drum sorting machines cause fruit damage by having the fruit pass directly through the screen cylinder and fall onto the guide plate after screening, and then roll into the collection frame, it is necessary to propose a drum-type peach sorting machine. Utility Model Content
[0005] The purpose of this invention is to provide a roller-type peach sorting machine, which effectively buffers the impact and rolling forces on peaches during the sorting process through the synergistic effect of the belt conveyor and the material guiding component, thereby reducing damage to the fruit surface.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A rotary peach sorting machine includes a machine body with multiple clockwise rotating drums mounted inside. Each drum is hollow and its surface is covered with screen holes, the diameter of which increases from left to right. Adjacent drums are guided by a first guide plate.
[0008] A belt conveyor is inserted inside the drum. A material guiding assembly is installed at the lower end of the drum on the belt conveyor. The material guiding assembly includes a second guide plate, a third guide plate, and a fourth guide plate, which are flexible. The second and third guide plates are fixedly connected to the belt conveyor, while the fourth guide plate is hinged to the top of the third guide plate. The angle between the third and fourth guide plates is adjustable.
[0009] Preferably, an adjusting plate is fixedly connected to the third guide plate, and a support plate is telescopically provided inside the adjusting plate, with one end of the support plate abutting against the back of the fourth guide plate.
[0010] Preferably, the support plate has equidistant adjustment holes and is fixedly connected to the adjustment plate by a pin.
[0011] Preferably, both the second and fourth guide plates are coated with sponge.
[0012] Preferably, a rotating shaft is also rotatably mounted inside the machine body, with a motor fixedly connected to one end of the shaft and a gear fixedly connected to the other end.
[0013] Preferably, one end of the roller is fixedly connected to a gear ring, which meshes with a gear.
[0014] Preferably, the screening inlet and the end of the machine body are respectively provided with a feed inlet and a collection trough.
[0015] Preferably, the upper openings of the second and fourth guide plates are adapted to the screening area of the drum, and the discharge end of the fourth guide plate is located directly above the second guide plate.
[0016] Preferably, the belt conveyor includes a conveyor belt, and the conveyor belt has a through hole at the position between the second guide plate and the third guide plate. The diameter of the through hole is smaller than the diameter of the screen hole of the corresponding roller.
[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0018] 1. This roller-type peach sorting machine uses a second and fourth guide plate to buffer the falling fruit. After receiving fruit falling from a height, the fourth guide plate will continue to transfer the fruit to the second guide plate, forming a multi-stage buffer. This effectively reduces the impact force on the fruit and lowers the risk of damage to the fruit surface. In addition, the angle between the third and fourth guide plates is adjustable, which can be adjusted according to the size and hardness of the fruit to ensure that fruits of different sizes can be effectively buffered.
[0019] 2. This roller-type peach sorting machine has through holes on the conveyor belt, and the diameter of the through holes is smaller than the diameter of the screen holes of the corresponding roller. After being guided by the second and fourth guide plates, the peaches are limited by the third guide plate, roll towards the corresponding through holes, and are stuck in the through holes and conveyed by the conveyor belt to prevent rolling and collision.

[0025] Please see Figures 1-3 A rotary peach sorting machine includes a machine body 1, in which multiple clockwise rotating rollers 11 are rotatably installed. Each roller 11 is hollow inside and its surface is covered with screen holes 111. The diameter of the screen holes 111 increases from left to right. Adjacent rollers 11 are guided by a first guide plate 16.
[0026] The clockwise rotation of the roller 11 allows the peaches to be evenly distributed on the surface of the roller 11 and move in an orderly manner, ensuring that the peaches can pass smoothly through the sieve holes 111 for sorting.
[0027] The increasing diameter of the sieve holes 111 allows peaches to pass through the sieve holes 111 in ascending order, achieving multi-level sorting.
[0028] A first guide plate 16 is provided between adjacent rollers 11 to guide peaches from one roller 11 to the next roller 11, buffer the impact of the falling peaches, avoid bumps and scratches caused by direct loading, protect the quality of the peaches, and ensure the continuity and stability of the sorting process.
[0029] Please see Figures 1-4 A belt conveyor 2 is inserted inside the drum 11. A guide assembly is installed on the belt conveyor 2 at the lower end of the drum 11. The guide assembly includes a flexible second guide plate 22, a third guide plate 23, and a fourth guide plate 26. The second guide plate 22 and the third guide plate 23 are fixedly connected to the belt conveyor 2, while the fourth guide plate 26 is hinged to the top of the third guide plate 23, and the angle between the third guide plate 23 and the fourth guide plate 26 is adjustable.
[0030] Among them, the belt conveyor 2 is a key component of the sorting machine, used to carry and transport peaches smoothly through the roller 11;
[0031] The guiding assembly is used to guide peaches from the roller 11 onto the conveyor belt 21, reducing the impact force when the peaches fall and protecting the quality of the peaches. The guiding assembly includes a second guiding plate 22, a third guiding plate 23 and a fourth guiding plate 26. The second guiding plate 22 is used to carry peaches falling from the lower screen hole 111 on the left and peaches rolling off the fourth guiding plate 26. The fourth guiding plate 26 is used to carry peaches falling from the higher screen hole 111 on the right. The third guiding plate 23 further guides the falling direction of the peaches and better controls the falling path of the peaches, so that the peaches can roll smoothly into the through hole 211.
[0032] The angle between the fourth guide plate 26 and the third guide plate 23 is adjustable, so that the tilt angle of the fourth guide plate 26 can be adjusted according to the size of the peach and the falling height, further reducing damage to the peach.
[0033] Please see Figure 4 To address the technical issue of adjusting the angle between the fourth guide plate 26 and the third guide plate 23, the following embodiment is provided:
[0034] An adjusting plate 24 is fixedly connected to the third guide plate 23. A support plate 25 is telescopically provided inside the adjusting plate 24. One end of the support plate 25 abuts against the back of the fourth guide plate 26. Adjusting holes are equidistantly opened on the support plate 25 and are fixedly connected to the adjusting plate 24 by a pin.
[0035] Specifically, first, pull the pin out of the adjustment hole of the support plate 25 to loosen the connection between the support plate 25 and the adjustment plate 24. Manually push or pull the support plate 25 to extend and retract within the adjustment plate 24, changing the relative position of the support plate 25 and the fourth guide plate 26. As the position of the support plate 25 changes, the angle of the fourth guide plate 26 will change accordingly. After the fourth guide plate 26 is adjusted to a suitable angle, reinsert the pin into the corresponding adjustment hole on the support plate 25 to ensure that the support plate 25 and the adjustment plate 24 are fixedly connected, locking the angle of the fourth guide plate 26.
[0036] Please see Figure 4 Both the second guide plate 22 and the fourth guide plate 26 have sponge 27 bonded to their surfaces.
[0037] Among them, sponge 27 has good elasticity, which can effectively buffer the impact of peaches falling from roller 11 onto the guide plate, reduce fruit damage, and protect the appearance and quality of peaches.
[0038] Please see Figure 2 To solve the technical problem of how the drum 11 rotates clockwise, the following embodiment is provided:
[0039] Inside the machine body 1, a rotating shaft 13 is also rotatably installed. One end of the rotating shaft 13 is fixedly connected to a motor, and the other end is fixedly connected to a gear 14. One end of the roller 11 is fixedly connected to a gear ring 12, which meshes with the gear 14.
[0040] The motor rotates counterclockwise.
[0041] Specifically, when the motor is started, the motor drives the rotating shaft 13 to rotate counterclockwise. The gear 14 rotates counterclockwise under the drive of the rotating shaft 13. Since the gear 14 meshes with the gear ring 12, the gear ring 12 rotates clockwise under the drive of the gear 14, thereby driving the roller 11 to rotate clockwise.
[0042] Please see Figure 3 The screening inlet 15 and the collection trough 17 of the machine body 1 are respectively provided at the screening inlet and the end.
[0043] Among them, the feed inlet 15 is located on the far left of the machine body 1, and the collection trough 17 is located on the far right of the machine body 1;
[0044] The feed inlet 15 is the entrance for peaches to enter the sorting machine. It can control the feeding speed of peaches to prevent them from piling up or getting stuck due to excessive feeding speed, and ensure that the peaches are evenly distributed on the roller 11.
[0045] The collection trough 17 is used to collect peaches that cannot be screened by the roller 11. That is to say, the peaches in the collection trough 17 are all larger than the diameter of the screen hole 111, which facilitates the later transfer, packaging and transportation.
[0046] Please see Figure 4 The upper openings of the second guide plate 22 and the fourth guide plate 26 are adapted to the screening area of the drum 11, and the discharge end of the fourth guide plate 26 is located directly above the second guide plate 22.
[0047] The opening is adapted to the screening area of the roller 11 to ensure that the peaches can fall smoothly from the roller 11 onto the guide plate after screening, and to prevent the peaches from falling directly onto the conveyor belt 21 through the screen holes 111 and causing injury.
[0048] The discharge end of the fourth guide plate 26 is located directly above the second guide plate 22, so that peaches falling from the high screen hole 111 can roll onto the fourth guide plate 26, and then roll from the fourth guide plate 26 to the second guide plate 22. The falling distance is short, forming a multi-stage buffer, with small impact force, reducing fruit damage and avoiding damage caused by excessive single falling height.
[0049] Please see Figure 1The belt conveyor 2 includes a conveyor belt 21. The conveyor belt 21 has a through hole 211 located between the second guide plate 22 and the third guide plate 23. The diameter of the through hole 211 is smaller than the diameter of the screen hole 111 of the corresponding roller 11.
[0050] The purpose of the through hole 211 on the conveyor belt 21 located between the second guide plate 22 and the third guide plate 23 is that after the peaches are guided by the second guide plate 22 and the fourth guide plate 26, they will fall between the third guide plate 23 and the second guide plate 22. Therefore, the through hole 211 is provided on the conveyor belt 21 within this range to facilitate the peaches rolling into the through hole 211.
[0051] The purpose of having a diameter smaller than that of the sieve hole 111 of the corresponding roller 11 is that when a peach rolls into the through hole 211, it will be directly stuck inside the through hole 211 and will not pass through the through hole 211, thus fixing the peach and preventing the peach from rolling and colliding when the conveyor belt 21 rotates.
[0052] Working principle: In this roller-type peach sorting machine, after the fruit falls through the screen holes 111 of the roller 11, it directly contacts the second guide plate 22 or the fourth guide plate 26. The fruit that falls on the fourth guide plate 26 will also be transferred to the second guide plate 22. This multi-stage buffer design reduces the height and impact force of the fruit when it falls. In addition, the angle between the fourth guide plate 26 and the third guide plate 23 is adjustable and can be adjusted according to the size of the fruit, further reducing the damage to the fruit.
[0053] After being guided by the guide plate, the fruit will fall into the through hole 211 on the conveyor belt 21 under the control of the third guide plate 23, and will be stuck in the hole without passing through it. This fixes the fruit and prevents it from rolling and colliding when the conveyor belt 21 rotates, thus further protecting the quality of the fruit.
