Description

TECHNICAL FIELD

[0001] The utility model belongs to material sorting equipment technical field especially relates to a feeding material distributing mechanism. BACKGROUND

[0002] Material sorting equipment is a kind of equipment for classifying and separating according to the physical properties (such as shape, size, density, weight, etc.) of material, and is widely used in mining, agriculture, food processing, recycling and other industries. Its working principle is usually through screening, vibration, air selection, magnetic separation and other ways, and effectively separates mixed materials according to different characteristics.

[0003] At present, the feeding mechanism of the morel screening system has multiple defects and deficiencies, mainly in the following aspects. First, there is no preliminary screening and distributing function. The current feeding system is only composed of a feeding hopper and a conveyor belt located below the hopper. The material has not been subjected to any preliminary screening and distribution before entering the subsequent screening equipment. This makes the material still in a mixed state when it enters the screening system, causing the subsequent screening equipment to be overloaded, reducing the screening efficiency and accuracy, and increasing the difficulty of subsequent processing.

[0004] Secondly, the material flow is not uniform, and the design of the feeding hopper and the conveyor belt cannot effectively control the flow and uniform distribution of the material. The uneven flow of the material during the conveying process may cause some materials to accumulate in a certain position, resulting in uneven distribution of the material during the screening process, affecting the screening effect and efficiency, and even causing jamming, thereby affecting the production continuity.

[0005] In addition, it cannot adapt to the characteristics of different materials. The current feeding mechanism design does not take into account the diversity and irregularity of morels and other materials. The irregular shape and size of morels can easily cause uneven stress during the screening process, making it difficult to accurately sort. The existing feeding system cannot be adjusted according to the different characteristics of the material, resulting in unsatisfactory screening results, especially when processing irregular-shaped materials.

[0006] Finally, there is a lack of efficient material guiding and distributing mechanism. The current feeding system lacks sufficient material guiding devices or distribution design, and the material cannot be efficiently distributed to different screening areas when entering the screening equipment. The lack of effective distribution mechanism makes it difficult for the screening equipment to fully exert its performance, resulting in a decrease in screening efficiency and increasing the complexity of material redistribution.

[0007] In summary, the existing feeding mechanism of the morel screening system has problems such as lack of preliminary screening, uneven material flow, inability to adapt to different material characteristics and lack of efficient distribution, which seriously limits the screening efficiency and screening accuracy of the product, and needs to be optimized and improved.

[0014] In the above technical solution, preferably, the middle guide slot and the side guide slots are installed on the base by a vibrator.

The number and position of the material guiding grooves are carefully designed to ensure uniform distribution of the material in different channels, thereby improving the sorting precision. In particular, the V-shaped structure of the material guiding groove enables the material to slide smoothly, reducing friction and accumulation.

[0021] In summary, the design of the feeding and distributing mechanism can improve the uniformity of material flow and screening precision through reasonable distribution and guiding mechanism, reduce the burden of subsequent screening equipment, and improve the overall screening production efficiency. In addition, the combination of the vibrator, material guiding wedge surface and material guiding groove enables the material to be efficiently and stably sorted, fully meeting the special needs of morel and other materials in the screening process.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this utility model.

[0026] To address the problems of existing morel mushroom screening systems, such as lack of preliminary screening and distribution functions, uneven material flow, inability to adapt to different material characteristics, and lack of efficient diversion mechanisms, this utility model provides a feeding and distribution mechanism. To further illustrate the structure of this utility model, a detailed description is provided below in conjunction with the accompanying drawings:

[0027] Please see Figs. 1-3 A feeding and distributing mechanism includes a base 1, a feeding hopper 2, a distributing tray 3, a distributing cone 4, and a guide chute 5. The base serves as a supporting frame for the material. Material passes sequentially through the feeding hopper, distributing cone, distributing tray, and guide chute before being fed into subsequent processes.

[0028] The feed funnel is directly fixed to the base. The lower part of the feed funnel is the discharge port, and the upper part is the feed port. It is shaped like an upward-opening trumpet, with the upper end being a flared feed port.

[0029] The material distribution tray is mounted on the base via a vibrator 6. The tray is located below the discharge port and receives the material discharged from it. A guide outlet is located on the side of the tray. Specifically, the tray includes a flat base plate 3-1, side plates 3-2 on both sides of the base plate, and a rear baffle 3-3 at the rear of the base plate. The guide outlet is a slot formed by the base plate and side plates of the tray. In this embodiment, the vibrator uses a four-spring foot design. This structure effectively isolates the screening device from its supporting structure, reducing unnecessary vibration transmission. The vibrator consists of a vibrator body and springs. The vibrator body, which integrates a motor, is connected to the screening equipment via springs, ensuring uniform vibration during operation. The four-spring foot design effectively disperses vibration and improves screening efficiency. The vibrator is purchased externally; various models and specifications of this type of vibrator are readily available on the market to meet the needs of different working conditions.

[0030] The material distribution cone is positioned on the material distribution tray with its top directly below the discharge port. The cone forms N guiding wedge surfaces 4-1. In this embodiment, the guiding wedge surfaces form slopes facing the material outlet, and all guiding wedge surfaces are symmetrically distributed with respect to the centerline of the material outlet. This centerline is essentially the line of symmetry between the two side plates. The guiding wedge surfaces include a central wedge surface and side wedge surfaces symmetrically positioned on either side of the central wedge surface. Furthermore, the central wedge surface has a ridge extending along the centerline of the material outlet and dividing the central wedge surface into two inclined sections. Specifically, the material distribution cone is formed from a flat metal sheet. In this design, the main function of the guiding wedge surfaces is to guide the material along a predetermined trajectory to the material outlet, aiding in the initial sorting of the material, especially suitable for screening special materials such as morel mushrooms. The wedge angle design of the central and side wedge surfaces is crucial. The central wedge surface should be designed as a gentle slope with a moderate wedge angle to effectively guide material flow without causing blockage or stagnation, ensuring smooth material flow. The side wedge surfaces can have slightly larger wedge angles to better guide material distribution to both sides and prevent material accumulation in the central area. The overall design should balance the size of the wedge angles to ensure smooth material flow and significant sorting effect during the guiding process, especially for effectively distinguishing materials of different specifications and shapes. The distributing cone is an integral component, installed on the distributing tray in a detachable and replaceable manner using screws. The rear of the distributing cone directly forms the end face that abuts against the rear baffle.

[0031] The primary function of the ridge design is to guide material flow and enhance sorting efficiency. By incorporating ridges on the central wedge-shaped surface, the material flow path is effectively divided into two directions, promoting material flow along different trajectories towards the guide outlet. This design prevents material deviation or mixing during flow, ensuring more uniform and orderly initial sorting. The presence of the ridges also increases friction between the guide surfaces, making material flow more directional and controllable, especially when processing irregularly shaped or lightweight materials (such as morel mushrooms), effectively preventing irregular distribution or jamming. Therefore, the ridge design not only improves sorting efficiency but also enhances the stability and reliability of the equipment.

[0032] At least two guide troughs are provided below the material outlet of the material distribution tray to receive the material discharged from the material outlet. In this embodiment, there are three guide troughs, including a central guide trough and side guide troughs symmetrically arranged on both sides of the central guide trough. The guide troughs have a V-shaped groove structure, formed by bending metal sheets, with the central guide trough located below the center of the material outlet. The central and side guide troughs are mounted on the base using a vibrator. The inner surface of the guide troughs can be treated with anti-slip coating to reduce material sliding resistance and ensure smooth material flow. For the design of the tilt angle, an appropriate tilt angle can prevent material accumulation or excessively rapid flow, ensuring stable material flow within the trough. The number and position of the guide troughs, through a reasonable layout and corresponding guide wedge surfaces, can effectively guide and distribute materials. The V-shaped groove structure helps materials slide smoothly within the trough, reducing accumulation or blockage, while its metal material ensures the durability and stability of the structure. Through the action of the vibrator, the feed chute provides continuous vibration, promoting material flow, further improving sorting efficiency, and ensuring that the material can smoothly enter the next screening process along the set trajectory. Overall, this design not only optimizes the material flow direction but also improves the equipment's working efficiency and the accuracy of material sorting.

[0033] Airfoil-shaped receiving plates 7 are installed on both sides of the side guide chute. These airfoil-shaped receiving plates form flat plates extending upwards in a V-shape along the guide chute. The airfoil-shaped receiving plates on the inner sides of the two side guide chutes are located above the middle guide chute. The airfoil-shaped receiving plates are installed in the side guide chute using bolts through elongated holes. The extension length of the airfoil-shaped receiving plates upwards along the side guide chute is adjustable via these elongated holes. A passageway is formed between the airfoil-shaped receiving plates on the inner sides of the two side guide chutes, located between the guide outlet and the guide chute. By adjusting the extension length of the airfoil-shaped receiving plates upwards along the side guide chute, the size of this passageway can be changed, further making the material distribution in the guide chute adjustable to meet material distribution requirements.

[0034] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
