Description

Technical Field

[0001] This utility model belongs to the field of ginkgo leaf sorting technology, and specifically relates to a sorting device. Background Technology

[0002] Ginkgo leaves are the dried leaves of the ginkgo tree. As a raw material for traditional Chinese medicine, they can be used to extract flavonoids and terpene lactones. The production and processing of ginkgo leaves mainly consists of pretreatment, primary processing, and deep processing. The pretreatment process of ginkgo leaves mainly includes sorting, washing, and drying. The sorting step is mainly used to screen out impurities such as gravel and branches mixed in with the ginkgo leaves.

[0003] Currently, vibrating screens are mainly used as ginkgo leaf sorting devices. The vibration of the screen separates impurities such as gravel and branches mixed with the ginkgo leaves. However, in practical applications, the thickness of the ginkgo leaves on the screen is closely related to the screening effect. When the ginkgo leaves are too thick, it is easy to fail to effectively sort the impurities mixed inside the ginkgo leaves; when the ginkgo leaves are too thin, the screening efficiency is poor. This makes the sorting device less effective in sorting ginkgo leaves.

[0004] Therefore, it is necessary to provide a sorting device to address the aforementioned technical problems.

[0033] like Figure 1 As shown, a guide plate 102 is fixedly installed inside the frame 1. The guide plate 102 is arranged below the feeding pipe 101 and is configured to cooperate with the screen 201. The guide plate 102 guides and conveys the ginkgo leaves discharged from the feeding pipe 101.

[0034] like Figure 1 As shown, a collection box 103 is slidably mounted inside the frame 1, and the collection box 103 is arranged below the screen 201. The collection box 103 collects and stores the impurities sorted out by the screen 201.

[0039] like Figure 1 As shown, a synchronous rotating shaft 207 is fixedly mounted between a pair of cams 202, and both ends of the synchronous rotating shaft 207 are rotatably connected to the frame 1. The synchronous rotating shaft 207 serves to mount, fix, and drive the rotation of the pair of cams 202.

[0040] like Figure 6 As shown, a drive motor 208 is fixedly mounted on one side of the frame 1, and the output shaft of the drive motor 208 is connected to the synchronous rotating shaft 207. The drive motor 208 provides power, and the synchronous rotating shaft 207 is rotated by controlling the operation of the drive motor 208.

The adjustable supporting rods 301 are used to support and fix the plurality of material spreading cones 302 and control the synchronous lifting of the plurality of material spreading cones 302.

[0047] As shown in the drawings, Figures 1 to 2 The side of the plurality of adjustable supporting rods 301 close to the screen 201 is fixedly assembled with a plurality of uniformly distributed material spreading cones 302, and the material guiding gap is formed between the plurality of material spreading cones 302 and the screen 201. The thickness of the material guiding gap is the thickness of the material spreading.

[0048] As shown in the drawings, Figures 1 to 2 The plurality of material spreading cones 302 are all provided with air exhaust cavities, and the air exhaust cavities penetrate through the material spreading cones 302. The air exhaust cavities are used to blow away the ginkgo leaves accumulated near the material spreading cones 302, thereby reducing the accumulation of ginkgo leaves.

[0049] Specifically, the material guiding gap decreases gradually from the feeding pipe 101 to the cam 202, facilitating the step-by-step thinning of the ginkgo leaves conveyed on the screen 201 and improving the efficiency of subsequent sorting of the ginkgo leaves.

[0050] As shown in Figures 3 to 5 the outer side of the telescopic supporting rod 303 is slidingly equipped with a retracting bottom rod 304, which is fixedly equipped above the screen 201. The retracting bottom rod 304 plays a role of accommodating and limiting the telescopic supporting rod 303 and guiding the sliding movement.

[0051] As shown in Figures 3 to 5 the outer side of the retracting bottom rod 304 is threadedly connected with a locking bolt 305, which is located at one end inside the retracting bottom rod 304 and in contact with the outer side of the telescopic supporting rod 303. The telescopic supporting rod 303 is locked and fixed by rotating the locking bolt 305.

[0052] As shown in Figures 3 to 5 a plurality of groups of the adjustable supporting rods 301 are each provided with a communication air cavity 306, and a plurality of exhaust cavities are in communication with the communication air cavity 306. The communication air cavity 306 facilitates the delivery of air to the plurality of exhaust cavities.

[0053] As shown in Figures 3 to 5 the ends of the plurality of groups of the material spreading cones 302 away from the adjustable supporting rods 301 are each provided with a blocking outer membrane 307, and the half edges of the blocking outer membranes 307 are fixedly connected with the outer walls of the material spreading cones 302. The half edges of the blocking outer membranes 307 are opened to control the conduction state of the exhaust cavities.

[0054] As shown in Figures 3 to 6 the two ends of the plurality of groups of the adjustable supporting rods 301 are each insertedly equipped with a gas guide pipe 308, and the ends of the plurality of groups of the gas guide pipes 308 away from the adjustable supporting rods 301 are in communication with a gas distribution plate 309. The gas guide pipe 308 and the gas distribution plate 309 cooperate to deliver air into the communication air cavity 306.

[0055] As shown in Figures 3 to 6 the gas distribution plate 309 and the retracting air bag 204 are connected with a delivery air pipe 310. The delivery air pipe 310 plays a role of connecting the gas distribution plate 309 and the retracting air bag 204, so that the gas in the retracting air bag 204 is delivered into the communication air cavity 306 along the delivery air pipe 310.

[0056] In specific use, the ginkgo leaves to be sorted can be added into the feeding pipe 101, and the ginkgo leaves are conveyed along the feeding pipe 101 and the guide plate 102 to the screen 201. At the same time, the synchronous rotating shaft 207 is driven to rotate by controlling the driving motor 208 to operate, and the pair of cams 202 can be synchronously rotated under the action of the synchronous rotating shaft 207, the screen 201 is intermittently lifted by the rotation of the cam 202, the screen 201 vibrates under the action of the cam 202 and the contraction air bag 204 and the reset spring 205, and the ginkgo leaves on the screen 201 are vibrationally sorted by the vibration of the screen 201.

[0057] In the process of vibrationally screening the ginkgo leaves by the screen 201, the ginkgo leaves conveyed on the screen 201 are spread by the plurality of spreading cones 302, so that the ginkgo leaves conveyed on the screen 201 are impurity-screened.

[0058] In addition, in the contraction process of the contraction air bag 204, the air inlet holes on the side of the contraction air bag 204 are blocked by the blocking inner membrane 209, so that the air in the contraction air bag 204 is conveyed into the communication air cavity 306 along the conveying air pipe 310, the guide air pipe 308 and the air guide plate 309, and is conveyed into the exhaust cavity along the communication air cavity 306. When the gas flows in the exhaust cavity, the blocking outer membrane 307 is expanded under the action of the gas, so that the ginkgo leaves accumulated near the spreading cone 302 are blown away by the exhaust gas of the spreading cone 302. Not only the ginkgo leaves conveyed on the screen 201 can be assisted to spread, but also the spreading stability of the spreading cone 302 can be ensured.

[0059] In the reset process of the contraction air bag 204, the blocking outer membrane 307 can block the exhaust cavity of the spreading cone 302, and the blocking inner membrane 209 is expanded under the action of the external gas pressure. The external air can enter the contraction air bag 204 along the air inlet hole, so that the contraction air bag 204 is reset.
