Description

Technical Field

[0001] This utility model relates to the field of reed processing and separation, specifically to a sand and gravel separation device for reed processing. Background Technology

[0002] Non-timber materials are widely distributed in land, rivers, lakes, swamps, and wetlands. During harvesting, these materials inevitably contain a large amount of mud, sand, gravel, and other impurities. These impurities not only cause severe wear and tear on engineered wood products production equipment but also lead to rapid damage to cutting tools during the furniture manufacturing process, becoming a key bottleneck restricting the improvement of non-timber engineered wood product quality. Traditional separation equipment suffers from low separation efficiency and inconvenient angle adjustment, making it difficult to meet the needs of large-scale industrial production. Especially when processing long-fiber materials such as reeds, existing equipment cannot achieve efficient cutting and sand / gravel separation in tandem, severely impacting production efficiency and product quality. Therefore, developing efficient sand / gravel separation equipment capable of material purification and meeting the process requirements for producing engineered wood products for furniture from non-timber materials is particularly important.

Detailed Implementation

[0017] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments:

[0018] like Figure 1-3 As shown, this application proposes a sand and gravel separation device for reed processing, including a support frame and a feeding belt conveyor installed on one side. The feeding belt conveyor is equipped with a dispersing roller at its discharge port. The dispersing roller evenly disperses the material onto the lower inclined stone and slag removal conveyor for conveying. The stones falling from the gap between the dispersing roller and the feeding belt conveyor slide down the inclined direction of the stone and slag removal conveyor to the waste slag transport belt conveyor for conveying.

[0019] The support frame can be a welded longitudinal steel frame to support the running parts of the entire equipment. The feeding belt conveyor can use a rubber conveyor belt with anti-slip texture; the belt width is preferably 3500-4000 mm, and the conveying speed is adjustable from 0.5-1.5 m / s. The scattering rollers can have evenly distributed raised strips on their surface, with the rotation speed controlled at 200-400 rpm to achieve uniform material dispersion. The tilt angle of the de-slag and slag removal conveyor is preferably 15-25 degrees. The waste slag transport belt conveyor can be a flat belt or a trough belt, installed below the discharge end of the de-slag and slag removal conveyor to facilitate the natural sliding of the stones.

[0020] This technical solution uses the rotation of a dispersing roller to initially disperse the reed raw material evenly, allowing any impurities like sand and gravel to fall naturally from the conveying gaps under gravity. Then, an inclined descrambling and deslag-removing conveyor effectively separates the sand and gravel from the reeds. Compared to traditional manual screening or vibrating screening methods, this equipment offers advantages such as strong continuous operation capability, high separation efficiency, and simple maintenance. The dispersing roller design ensures uniform material dispersion, while the multi-stage conveying system enables automated collection and transportation of sand and gravel, effectively solving the technical challenge of separating sand and gravel impurities from reed raw materials.

[0021] Furthermore, this application also proposes to install a discharge cutting roller obliquely above the feeding belt conveyor for cutting long reeds.

[0022] The unloading and cutting roller can be a rotating roller structure with cutting blades, which can be arranged in a spiral or straight line. As a preferred embodiment, a rubber layer can be provided on the roller surface to increase friction and protect the cutting blades. The cutting blades should ideally be 100-300mm in length for longer reeds to facilitate subsequent scattering.

[0023] This technical solution effectively solves the problem of long reeds entanglement in the material feeding stage by adding a cutting device. Specifically, the long reeds are cut into short sections, which prevents entanglement at the dispersing rollers and ensures uniform material dispersion. At the same time, the cut reeds are easier to disperse on the desanding conveyor, improving sand and gravel separation efficiency. This design utilizes the space above the existing conveyor to arrange the cutting rollers without adding an extra power unit, resulting in a compact structure and simple operation.

[0024] Furthermore, this application also proposes that the unloading cutting roller, the scattering roller, and the stone and slag removal conveyor are installed on the support frame from top to bottom.

[0025] Specifically, the unloading and cutting roller is located at the top for cutting long reeds; the scattering roller is located in the middle for evenly dispersing the material; and the stone and slag removal conveyor is located at the bottom for separating sand and gravel impurities. This top-down installation method achieves overall structural stability through a support frame. As a preferred embodiment, each component can be bolted to a pre-set mounting position on the support frame, which can be designed as a multi-layer frame structure with corresponding mounting interfaces on each layer.

[0026] Therefore, this technical solution optimizes equipment layout, achieving both a continuous material handling process and maximized space utilization. The top-down installation method ensures that reeds are first cut, then scattered, and finally separated into sand and gravel, forming a continuous production line. Compared to existing technologies, this layout not only reduces material transfer steps but also avoids material spillage caused by dispersed equipment, effectively improving sand and gravel separation efficiency.

[0027] Furthermore, this application also proposes that the discharge end of the de-rocking and slag-removing conveyor is hinged to one side of the support frame, and the tilt angle of one side of the de-rocking frame is adjusted by an angle adjustment mechanism.

[0028] Specifically, the angle adjustment mechanism, by changing the tilt angle of the de-stoner frame, can adapt to different material separation needs based on the shape, length, and amount of sand and gravel in the raw materials. When the conveyed reed material is short, the tilt angle can be increased to accelerate the falling of stones; when the conveyed reed material is long, the tilt angle can be decreased to extend the separation time, thus ensuring stable conveying of the reed material. For materials with a high stone content, the tilt angle can be increased to accelerate the falling of stones; for materials with a low stone content, the tilt angle can be decreased to extend the separation time. Compared to a fixed-angle de-stoner frame, this adjustable design can more effectively adapt to the sand and gravel separation needs under different working conditions, improving separation efficiency.

[0029] Furthermore, this application also proposes that the angle adjustment mechanism includes tie rods hinged to both sides of the descraper frame, the top of the tie rods being hinged to a screw passing through the side crossbeam of the support frame, and the side crossbeam of the support frame being provided with a support nut screwed to the screw.

[0030] Specifically, the tie rod can be made of metal or high-strength composite material, and its hinge points with the descraper frame are located symmetrically on both sides of the frame. The screw can use a trapezoidal thread with a thread fit accuracy of no less than grade 7. The support nut can be a double nut for self-locking and anti-loosening.

[0031] Therefore, this technical solution achieves precise adjustment of the tilt angle of the desander frame through a screw-nut transmission mechanism. When the support nut is rotated, the screw generates axial displacement, driving the tie rod to change the tilt angle, thereby adjusting the working angle of the desander frame. This mechanical adjustment method features simple structure, high adjustment accuracy, and reliable locking, and can adapt to the conveying angle requirements of different material separation conditions. Compared with a fixed angle structure, it effectively solves the problem of decreased separation efficiency caused by changes in material characteristics, and ensures optimal sand and gravel separation effect by adjusting the conveying tilt angle in real time.

[0032] Furthermore, this application also proposes that, in addition to the sliding frames installed at the rear ends of both sides of the stone machine frame, the sliding frames are matched with the arc-shaped support frames fixed to the support frames, and the arc-shaped support frames have arc-shaped grooves, on which the fixing bolts for fixing the sliding frames are installed in the arc-shaped grooves.

[0033] The sliding frame, a key component connecting the descraper frame and the arc-shaped support frame, can be fixed to both sides of the rear end of the descraper frame using welding or bolts. The arc-shaped support frame is pre-fixed to the support frame by welding; its arc-shaped groove can be machined, with the groove width slightly larger than the diameter of the fixing bolts for adjustment. Hexagonal head bolts with lock nuts are preferred for fixing; tightening the nuts secures the sliding frame. This technical solution improves the stability of the descraper frame through the cooperative structure of the sliding frame and the arc-shaped support frame.

[0034] Furthermore, this application also proposes that a feeding frame be installed on the upper part of the feeding belt conveyor to prevent material from spreading and spilling. The feeding frame can adopt various structural forms to achieve the anti-spillage function. Specifically, the feeding frame can be designed as a U-shaped structure with baffles on both sides, and the height of the baffles can be adjusted according to the characteristics of the material;

[0035] The implementation principle of the sand and gravel separation equipment for reed processing in this application embodiment is as follows:

[0036] The reed raw material is fed into the loading rack 2 by a loader, and then conveyed forward to the unloading cutting roller 4 by the speed-adjustable loading belt conveyor 3. The unloading cutting roller 4 evenly disperses the reeds and cuts any excessively long material with blades mounted on it. The dispersed and cut material falls evenly onto the dispersing roller 5 for further shaking and forward conveying. During this process, stones and dirt adhering to and mixed in with the material fall along the gap at the front end of the dispersing roller 5 to the rear of the stone removal and slag removal conveyor 7. The clean material falls forward to the front of the stone removal and slag removal conveyor 7 as the dispersing roller rotates. Due to the combined effect of gravity and fluidity, waste such as mud, sand and stones roll down to the waste slag transport belt conveyor 11 and are sent into the waste hopper. The clean reed material is conveyed to the subsequent processing equipment 12 for cutting processing as the belt of the stone removal and slag removal conveyor 7 rotates. At the same time, the angle of the angle adjustment mechanism 8 can be adjusted appropriately according to the different raw materials to achieve the best cleaning effect.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
