Abstract
Description
Technical Field
[0001] This utility model relates to a sorting device, and more particularly to a sorting machine for the green peel and seeds of Torreya grandis. Background Technology
[0002] Torreya grandis is the seed of a plant in the Taxaceae family; its fruit is a nut, about the size of a date, olive-shaped, pointed at both ends, and oval in shape. The four alkaloids contained in Torreya grandis have a significant inhibitory effect on lymphocytic leukemia and are beneficial in the treatment and prevention of highly malignant lymphosarcoma. Furthermore, because it contains a relatively high amount of vitamin A and other components beneficial to the eyes, it has preventative and alleviating effects on symptoms such as dry eyes, excessive tearing, and night blindness.
[0003] The production process of Chinese torreya nuts mainly includes harvesting, peeling, washing, sieving, and roasting. The peeling process aims to remove the outer skin from the green nuts. Currently, friction peeling is commonly used, which involves a fixed inner cylinder and a rotating outer cylinder. The peel is removed by friction between the inner and outer walls of the outer cylinder and the green nuts, allowing the seeds to escape through openings in the outer cylinder. Therefore, peeled Chinese torreya nuts are prone to contain unpeeled nuts and outer skin, necessitating sorting.
[0004] Chinese patent CN217342197U discloses a sorting mechanism for peeling Torreya grandis seeds, comprising a pair of spaced-apart sorting rollers, the distance between the two rollers being greater than the size of the kernel but less than the size of the unripe kernel; the sorting rollers are inclined and rotate synchronously inward. This sorting mechanism can only sort and discharge the kernel and unripe kernel using the two sorting rollers, and cannot effectively sort the pericarp mixed in with the Torreya grandis seeds and the unpeeled green kernels, requiring manual sorting, resulting in low sorting efficiency. Utility Model Content
[0005] The technical problem to be solved by this utility model is to provide a sorting machine for green husks, fruits, and seeds of Torreya grandis that can effectively separate and discharge them separately, with good sorting effect and high working efficiency.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A sorting machine for unripe Torreya grandis peel and seeds includes a frame that is stepped, with the front lower than the back. A second roller module and a first roller module are respectively arranged longitudinally at the front and rear upper ends of the frame. The first and second roller modules are racetrack-shaped circulating conveyor roller tracks. The gap between two adjacent conveyor rollers of the first roller module is smaller than the size of the unripe Torreya grandis fruit and seeds. The gap between two adjacent conveyor rollers of the second roller module is larger than the size of Torreya grandis seeds but smaller than the size of the unripe Torreya grandis fruit.
[0008] A rotatable roller brush and a blower assembly are arranged sequentially above the first roller module on the frame. The air outlet of the blower assembly is a rectangular long opening, which is used to blow the green skin through the gap between two adjacent conveyor rollers of the first roller module.
[0009] A first conveyor belt mechanism and a second conveyor belt mechanism are respectively provided on the frame between the upper and lower conveyor rollers of the first and second roller modules. The first conveyor belt mechanism and the second conveyor belt mechanism are arranged in the transverse direction of the frame and are respectively used to convey the green husks blown down through the gap of the first roller module and the torreya seeds falling through the gap of the second roller module.
[0010] As a further preferred option, an inclined feed baffle is provided at the rear end of the frame above the first roller module to guide the input material onto the first roller module.
[0011] As a further preferred option, a transition chute is provided on the frame between the first roller module and the second roller module to guide the green nut and seeds of Torreya grandis on the first roller module onto the second roller module.
[0012] As a further preferred option, a front chute is provided at the front end of the second roller module on the frame for exporting the sorted unripe torreya nuts.
[0013] As a further preferred embodiment, the blowing assembly consists of two high-pressure centrifugal fans, which are fixed to the protective plates on both sides of the first roller module by fan brackets. An exhaust nozzle is connected to the exhaust port of the centrifugal fan. The exhaust nozzle is an isosceles trapezoid with a narrow top and a wide bottom, and the lower end is the air outlet. The width of the air outlet is smaller than the gap between two adjacent conveying rollers of the first roller module.
[0014] The beneficial effects of this utility model are as follows:
[0015] Because the gap between two adjacent conveyor rollers of the first roller module is smaller than the size of the unripe fruit and seeds of Torreya grandis, the roller brush can spread out the unripe peel, fruit, and seeds of Torreya grandis fed onto the first roller module. The blowing assembly can blow the unripe peel down through the gap between the two adjacent conveyor rollers of the first roller module and discharge it through the first conveyor belt mechanism. Because the gap between two adjacent conveyor rollers of the second roller module is larger than the size of Torreya grandis seeds but smaller than the size of unripe fruit, the Torreya grandis seeds can fall through the gap between the conveyor rollers of the second roller module and discharge it through the second conveyor belt mechanism. Thus, the unripe peel, fruit, and seeds of Torreya grandis can be effectively separated and discharged separately, with good sorting effect and high working efficiency. Attached Figure Description

[0021] 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 scope of protection of the present utility model.
[0022] like Figure 1-4 As shown, this utility model relates to a sorting machine for the peel and seeds of Torreya grandis, including a frame 1. The frame 1 is stepped, with a lower front and a higher rear. A second roller module 12 and a first roller module 2 are respectively arranged longitudinally at the upper front and rear ends of the frame 1, with the second roller module 12 being lower than the first roller module 2. The first and second roller modules are respectively racetrack-shaped circulating conveyor roller tracks. The circulating conveyor roller tracks include two chain conveying mechanisms 11 symmetrically arranged and installed on the frame 1. A plurality of conveying rollers 17 are evenly distributed between the chains of the two chain conveying mechanisms 11. A reduction motor 14 fixed on the frame 1 is connected to the drive shaft at the front end of the chain conveying mechanism 11 through a chain transmission mechanism 15.
[0023] The gap between two adjacent conveying rollers 17 of the first roller module 2 is smaller than the size of the green fruit and seeds of Torreya grandis, and the gap between two adjacent conveying rollers 17 of the second roller module 12 is larger than the size of Torreya grandis seeds but smaller than the size of the green fruit of Torreya grandis; so that the green peel, fruit and seeds of Torreya grandis can be sorted sequentially through the gap between two adjacent conveying rollers 17 of the first and second roller modules.
[0024] A protective cover plate 4 is fixed on both sides of the first roller module 2 on the frame 1. A rotatable roller brush 5 and a blowing assembly 7 are sequentially installed on the protective cover plate 4 above the first roller module 2. The two ends of the central shaft of the roller brush 5 are fixed to the protective cover plate 4 through bearing seats and bearing seat brackets 6. The air outlet of the blowing assembly 7 is a rectangular long opening close to the conveying roller 17 of the first roller module 2, which is used to blow the green skin through the gap between two adjacent conveying rollers 17 of the first roller module 2.
[0025] The blowing assembly 7 consists of two units arranged front and rear, each using a high-pressure centrifugal fan 8. They are fixed to the protective plates 4 on both sides of the first roller module 2 by the fan bracket 9. An exhaust nozzle 10 is sealed and connected to the exhaust port of the centrifugal fan 8. The front of the exhaust nozzle 10 is an isosceles trapezoid that is narrow at the top and wide at the bottom, and the lower end is the air outlet. The width of the air outlet is smaller than the gap between two adjacent conveying rollers 17 of the first roller module 2.
[0026] On the frame 1, between the upper and lower conveyor rollers 17 of the first and second roller modules, a first conveyor belt mechanism 3 and a second conveyor belt mechanism 13 are respectively provided. The first conveyor belt mechanism 3 and the second conveyor belt mechanism 13 are driven by the conveyor belt reduction motor 16 through the chain 21 and arranged laterally along the frame 1, so that their conveying direction is spatially perpendicular to the conveying direction of the first and second roller modules. They are used to convey the green husks blown down through the gap of the first roller module 2 and the torreya seeds falling through the gap of the second roller module 12.
[0027] An inclined feed baffle 18 is fixed between the protective plates 4 on both sides of the rear end of the frame 1, above the first roller module 2, so as to guide the input material onto the first roller module 2.
[0028] An inclined transition chute 19 is fixed on the frame 1 between the first roller module 2 and the second roller module 12 to guide the green fruit and seeds of Torreya grandis on the first roller module 2 onto the second roller module 12.
[0029] A front chute 20 is fixed on the frame 1 at the front end of the second roller module 12 for exporting the sorted green torreya nuts.
[0030] During operation, the peeled torreya nuts are fed onto the feed baffle 18 by the lifting equipment. They then enter the first roller module 2 through the feed baffle 18. Under the action of the roller brush 5, the peel, fruit, and seeds are spread evenly on the conveyor rollers 17 of the first roller module 2 and moved forward under the drive of the first roller module 2. When passing through the blowing assembly 7, the green peel is blown down through the gap between the two adjacent conveyor rollers 17 of the first roller module 2 by the action of the two centrifugal fans 8 and falls onto the first conveyor belt mechanism 3, and is then conveyed out by the first conveyor belt mechanism 3. The air volume of the centrifugal fan 8 at the front is controlled to be greater than that of the centrifugal fan 8 at the rear, so that if the green peel cannot be blown down the first time, it will be completely blown down when passing through the second blowing assembly 7. Unblown Torreya nuts and seeds that are not blown off fall onto the second roller module 12 through the transition chute 19. Torreya seeds fall into the second conveyor belt mechanism 13 through the gap between two adjacent conveyor rollers 17 of the second roller module 12 and are discharged through the second conveyor belt mechanism 13. Meanwhile, the unblown Torreya nuts continue to move forward with the second roller module 12 and fall into the collection box through the front chute 20 for peeling again.
[0031] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and the illustrations shown and described herein.
