Description
Technical Field
[0001] This utility model belongs to the field of coffee bean peeling technology, specifically, it relates to a coffee bean peeling and crushing sorting device. Background Technology
[0002] With the continuous expansion of the coffee consumption market, coffee bean processing technology is receiving increasing attention. Coffee bean peeling and crushing sorting devices play a crucial role in the coffee bean processing process.
[0003] Firstly, traditional coffee bean peeling technology typically uses mechanical friction to remove the outer skin of the coffee beans. This mechanical friction peeling method uses rollers and other components in the peeling equipment to squeeze and rub the coffee beans, separating the outer skin from the beans. This method can achieve high-efficiency peeling to a certain extent, improving production efficiency. At the same time, some advanced peeling equipment is also equipped with auxiliary devices such as fans to promptly blow away the separated outer skin, achieving the desired peeling and separation effect.
[0004] However, existing technologies have the following problems in use: during the peeling process, due to the differences in the size, shape and hardness of coffee beans, peeling equipment is prone to causing coffee beans to break and produce broken fruit. After the broken fruit is mixed with the whole fruit, a lot of manpower is required for sorting. Therefore, existing coffee bean peeling equipment can only separate coffee beans from the outer skin, and has the problem of not being able to sort the product quality. Utility Model Content

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.
[0027] like Figure 1 Figure 2 shows an embodiment of a coffee bean peeling and crushing sorting device provided by this utility model. In this embodiment, a peeling box 10 is included, and a peeling roller and a fan for separating the outer skin are provided inside the peeling box 10. The bottom of the discharge plate 12 of the peeling box 10 is provided with a sorting mechanism 11. The sorting mechanism 11 includes a motor 15, a movable connecting rod 17, a sorting tray 13 and a sorting screen 14. The sorting screen 14 is fixedly installed inside the sorting tray 13 by bolts. The bottom of the sorting tray 13 is provided with a crushed fruit discharge channel 18, and the front end of the sorting tray 13 is provided with a whole fruit discharge channel 19. The motor 15 is fixedly connected to the inner wall of the peeling box 10, and the output end of the motor 15 is fixedly connected to a rotating wheel 16. A convex shaft 20 is provided on the outer side of the rotating wheel 16. The convex shaft 20 is connected to one side of the sorting tray 13 through the movable connecting rod 17. The other side of the sorting tray 13 is movably connected to the top of the support frame 22 through a swinging member 21.
[0028] The peeling roller includes a drive roller and a driven roller. The drive motor is located outside the peeling box 10 and is fixedly connected to one end of the shaft of the drive roller. The other end of the shaft drives the driven roller through a drive wheel, a transmission belt, and a driven wheel on the driven roller shaft. This is used to peel the coffee beans. The blower is located on the side wall of the peeling box 10. The blower outlet is located above the discharge plate 12. This is used to separate the falling coffee beans and the peeled outer skin residue. The collection box is slidably located inside the peeling box 10 to collect the outer skin residue blown off by the blower.
[0029] In the above technical solution, one side of the sorting tray 13 is movably connected to the bottom of the discharge plate 12 via an upper swing link 23, and the upper swing link 23 is used to hoist and support the sorting tray 13.
[0030] In use, coffee beans to be peeled are poured into the feed inlet at the top of the peeling box 10, and guided evenly onto the peeling rollers by the feed guide plate 24 at the feed inlet. The peeling rollers inside the peeling box 10 rub the coffee beans to peel them. At the same time, the blower is started to blow off the outer skin of the coffee beans, which falls into the collection box. The peeled coffee beans fall from the discharge plate 12 inside the peeling box 10 onto the sorting tray 13 of the sorting mechanism. The motor 15 drives the rotating wheel 16 to rotate, and the convex shaft 20 on the outside of the rotating wheel 16 pushes the sorting tray 13 through the movable connecting rod 17. Under the action of the movable connecting rod 17 and the swinging component 21, the sorting tray 13 makes an upward reciprocating motion on the support frame 22. The coffee beans are subjected to vibration and inertial force on the sorting screen 14 inside the sorting tray 13. Fruit pieces smaller than the mesh size of the sorting screen 14 fall through the screen into the fruit piece discharge channel 18 and are discharged; while larger whole fruits move towards the whole fruit discharge channel 19 under inertia. The receiving base plate 25 at the front end of the whole fruit discharge channel 19 assists in the smooth discharge of whole fruits and prevents whole fruits from falling into the fruit piece discharge channel.
[0031] Furthermore, in the above technical solution, the support frame 22 is fixedly connected to the bottom end of the peeling box 10 to support the peeling box 10 and the sorting tray 13.
[0032] Furthermore, in the above technical solution, one end of the movable connecting rod 17 is movably hinged to the convex shaft 20, and the other end is movably hinged to the connecting shaft on the sorting tray 13, and the connecting shaft is fixedly connected to one side of the sorting tray 13.
[0033] Furthermore, in the above technical solution, there are two sets of swinging components 21, with their bottom ends being movably hinged to the top two sides of the support frame 22.
[0034] Furthermore, in the above technical solution, the top of the swing member 21 is movably hinged to the bottom of both sides of the outer end of the sorting tray 13, and is used to follow the movable connecting rod 17 to cooperate with the sorting tray 13 to reciprocate on the support frame 22.
[0035] Furthermore, in the above technical solution, the peeling box 10 is equipped with a collection box for holding the outer skin of coffee beans.
[0036] Furthermore, in the above technical solution, the top of the peeling box 10 is provided with a feed inlet, and a feeding guide plate 24 is provided between the feed inlet and the peeling roller.
[0037] Furthermore, in the above technical solution, a receiving base plate 25 is provided at the whole fruit discharge channel 19. The receiving base plate 25 is used to assist the whole fruit discharge channel 19 in discharging material and prevent whole fruits from falling into the broken fruit discharge channel 18.
[0038] Furthermore, in the above technical solution, the sorting screen 14 has square mesh openings with a mesh size of 4mm to 7mm.
[0039] Specifically, the principle of this invention is as follows: During use, coffee beans to be peeled are poured into the feed inlet at the top of the peeling box. A guide plate at the feed inlet guides the coffee beans to fall evenly onto the peeling rollers. The peeling rollers inside the peeling box rub the coffee beans to remove their skins. Simultaneously, a blower starts, blowing off the outer skin of the coffee beans, which falls into a collection box. The peeled coffee beans fall from the discharge plate of the peeling box onto the sorting tray of the sorting mechanism. The motor starts, driving the rotating wheel to rotate, and the convex shaft on the outside of the wheel pushes the sorting tray through a movable connecting rod. Under the action of the movable connecting rod and the swinging component, the sorting tray reciprocates on the support frame. The coffee beans are subjected to vibration and inertial force on the sorting screen inside the sorting tray. Crushed beans smaller than the mesh size of the sorting screen fall through the screen into the crushed fruit discharge channel. Larger whole fruits move towards the whole fruit discharge channel due to inertia. The receiving plate at the whole fruit discharge channel helps the whole fruits to be discharged smoothly and prevents them from falling into the broken fruit discharge channel.
