[0001] This utility model relates to the technical field of longan processing equipment, specifically to a longan color sorter. Background Technology

[0002] In the longan processing industry, consumers have increasingly higher requirements for the quality of longan. Longan color sorters can accurately screen out longan particles with different colors, such as immature, diseased, or spoiled longans, thereby ensuring the overall quality and appearance of the product and meeting the market demand for high-quality longan products.

[0003] In existing longan color sorters, the longan is typically fed into the sorting mechanism via a chute. However, debris mixed in with the longan can also enter the sorting mechanism. The sorting mechanism cannot remove the debris, resulting in debris being mixed with the good products and affecting product quality. Utility Model Content

[0004] The purpose of this invention is to design a longan color sorter to solve the technical problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a longan color sorter, comprising a color sorting mechanism, a hopper, and a trough. The hopper is fixedly connected to the feed end of the color sorting mechanism via a bracket. The trough is disposed at the discharge end of the hopper, and the discharge end of the trough is connected to the feed end of the color sorting mechanism. A vibration device is connected to the bottom of the trough. A screen is fixedly connected to the trough near the discharge end, and a collection trough for collecting debris is provided directly below the screen.

[0006] Furthermore, the material collection trough is fixedly connected to the bracket by a fastener.

[0007] Furthermore, the discharge end of the material trough is provided with a conveyor belt mechanism, and the discharge end of the conveyor belt mechanism is connected to the feed end of the color sorting mechanism.

[0008] Furthermore, the discharge end of the hopper is provided with a baffle for controlling the discharge amount of longan, and the baffle is fixedly connected to the hopper through an adjustment component.

[0009] Furthermore, the adjustment assembly includes a limiting post fixed to the hopper and a locking knob for clamping the baffle. The locking knob is threadedly connected to the limiting post, and the baffle is provided with a limiting groove that is compatible with the limiting post.

[0010] Furthermore, the color sorting mechanism includes a color sorting sensor, a spray valve, and a signal processor, wherein the color sorting sensor and the spray valve are electrically connected to the signal processor.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model uses a vibration device to drive the material trough to vibrate for feeding. When the longan passes through the screen, the debris mixed in with the longan will be shaken off and fall into the collection trough, avoiding the debris from mixing with the good products and effectively improving the quality of the product.

[0015] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0016] Example: Please refer to Figure 1-2 A longan color sorter includes a sorting mechanism 1, a hopper 2, and a trough 3. The hopper 2 is fixed to the feed end of the sorting mechanism 1 via a bracket 4. The trough 3 is located at the discharge end of the hopper 2, and its discharge end is connected to the feed end of the sorting mechanism 1. A vibration device 5 is connected to the bottom of the trough 3 away from the discharge end. The vibration device is mounted on the bracket 4. A screen 6 is fixed to the trough 3 near the discharge end. A collection trough 7 for collecting debris is located directly below the screen 6. Longans are placed in the hopper 2 and fall from the bottom of the hopper 2 into the trough 3. The vibration device drives the trough 3 to vibrate, causing the longans to be conveyed from the trough 3 to the sorting mechanism 1. When the longans pass through the screen 6, debris is automatically shaken off and falls into the collection trough 7, achieving automatic filtration and collection of debris, preventing debris from mixing with good products, and effectively improving product quality. The bottom of the collection trough 7 has a discharge port, which facilitates quick cleaning of debris in the collection trough 7. The material collection trough 7 is fixedly connected to the bracket 4 by a fastener, which can be bolts, facilitating the quick assembly of the material collection trough 7.

[0017] In an optional embodiment, the discharge end of the material trough 3 is equipped with a conveyor belt mechanism 8, which is connected to the feed end of the color sorting mechanism 1. The conveyor belt mechanism 8 transports the longan to the color sorting mechanism 1, ensuring a continuous flow of longan. The color sorting mechanism 1 includes a color sorting sensor, a spray valve, and a signal processor. The color sorting sensor and the spray valve are electrically connected to the signal processor. The color sorting sensor is used to collect data on the longan, the spray valve is used to spray gas onto the defective products flowing into the color sorting mechanism 1, causing the defective products to flow from the defective product channel into the defective product frame, and the signal processor is used to analyze the signals transmitted by the color sorting sensor and control the operation of the spray valve. More specifically, the conveyor belt mechanism 8, the color sorting sensor, the spray valve, and the signal processor are all prior art, and their specific structures and working principles will not be described in detail here.

[0018] The discharge end of the hopper 2 is equipped with a baffle 9 for controlling the discharge amount of longan. The baffle 9 is fixedly connected to the hopper 2 via an adjusting component. Longan flows out from the gap between the hopper 2 and the trough 3. The discharge amount of longan is controlled by adjusting the size of the gap through the baffle 9.

[0019] In the above embodiment, the adjusting component includes a limiting post fixed to the hopper 2 and a locking knob 10 for clamping the baffle 9. The locking knob 10 is threadedly connected to the limiting post. Manually locking the knob 10 causes it to screw inward, so that the end face of the locking knob 10 near the baffle 9 is in close contact with the baffle 9, thereby clamping the baffle 9 and fixing it. The baffle 9 is provided with a limiting groove 11 that matches the limiting post. Manually rotating the locking knob 10 releases the baffle 9 from the hopper 2, allowing the baffle 9 to slide freely on the outer wall of the hopper 2. The cooperation between the limiting post and the limiting groove 11 allows the baffle 9 to precisely control the gap between the hopper 2 and the trough 3.

[0020] The working principle of this utility model is as follows: When in use, the color sorting mechanism 1 is activated, and longan is placed into the hopper 2. The discharge rate of longan is controlled by the baffle 9. The longan falls from the hopper 2 onto the trough 3. The vibration device 5 drives the trough 3 to vibrate, and the screen 6 vibrates along with the trough 3. The longan first passes through the screen 6 and then falls from the discharge end of the trough 3 onto the conveyor belt mechanism 8. The conveyor belt mechanism 8 transports the longan to the color sorting mechanism 1, which accurately filters out longan particles of different colors. When the longan flows through the screen 6, the debris mixed in with the longan will be shaken off and fall into the collection trough 7, avoiding the debris from mixing with the good products and effectively improving the quality of the product.

[0021] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
