Description

Technical Field

[0001] This utility model relates to the field of material feeding machine technology, and in particular to a special feeding machine for low-density fibrous materials. Background Technology

[0002] In the fields of biomass energy (such as biomass pellet fuel production and biomass gasification power generation), green feed processing, organic fertilizer fermentation, and environmentally friendly building materials (such as straw-based lightweight boards), short straw pellets (5-10mm in length and 1-5mm in diameter), rice husks, and similar low-density fibrous materials (such as crushed corn cob fiber and peanut shell fiber) are core raw materials for the resource utilization of agricultural waste, and their demand for large-scale application continues to rise. These materials share common physical characteristics such as low density (bulk density is generally only 80-150kg / m³), light and fluffy texture, strong fiber interweaving, easy moisture absorption and clumping, and extremely poor material flowability. This means that in the "feeding stage" of the production process, they must meet the core requirements of "continuous and stable conveying, no blockage, and precise adaptation to downstream processes (such as high-temperature pelleting and microbial fermentation)".

[0003] Currently, most existing feeding equipment is designed for high-density granular (such as corn, plastic granules), blocky (such as wood scraps), or fine powdery (such as flour, lime powder) materials. It does not consider the unique characteristics of low-density fibrous materials such as short straw particles and rice husks. Direct application of these materials generally results in significant compatibility issues, with specific technical pain points as follows: High-frequency clogging and severely insufficient stability and continuity: Low-density fibrous materials such as short straw have low density and relatively light weight per unit volume. They cannot fall smoothly by gravity alone and easily clump together to form "fiber clumps," blocking the channel and preventing the material from falling smoothly. On average, the machine needs to be stopped every 1-2 hours for disassembly and cleaning, with each cleaning session taking 20-30 minutes. This severely disrupts the continuous production process, is time-consuming and labor-intensive, and seriously affects production efficiency. Utility Model Content

[0004] Therefore, it is necessary to provide a special feeder for low-density fibrous materials to address the problems of easy "clumping" and "clogging".

[0005] This utility model is achieved through the following technical solution: It relates to a special feeder for low-density fibrous materials, comprising a housing, a flywheel drive shaft, and a vibrating and dispersing assembly. The housing and flywheel drive shaft are rotatably connected. The vibrating and dispersing assembly includes a vibrating screen, a vibrating slide, a rotating cone, a cone fixing frame, a transverse bevel gear, and a longitudinal bevel gear. The vibrating screen is slidably connected to the vibrating slide. The vibrating slide is fixedly connected to the bottom of the housing. The rotating cone is rotatably connected to the cone fixing frame. The cone fixing frame is fixedly connected to the inside of the housing. The rotating cone is coaxially fixedly connected to the transverse bevel gear. The transverse bevel gear and the longitudinal bevel gear mesh with each other. The longitudinal bevel gear is coaxially fixedly connected to the flywheel drive shaft.

[0006] The rotating cone disperses the low-density fibrous material entering the chamber, evenly distributing it onto the vibrating screen. As the screen vibrates back and forth driven by the traction rod, the dispersed fibrous material remains in constant motion, preventing clumping and allowing it to pass through the screen and exit the chamber into the discharge port. Compared to traditional feeders, this method effectively solves the problems of low-density fibrous materials easily clumping and clogging, improving the feeder's stability and reliability, and significantly increasing production efficiency.

[0007] Furthermore, the vibrating and dispersing assembly also includes a traction rod, two tension springs, and two transmission rods. The traction rod is fixedly connected to the vibrating screen. The two tension springs are fixedly connected to both ends of the traction rod. The two transmission rods are fixedly connected to the traction rod.

[0008] Furthermore, it also includes two fixed supports and a discharge port, with two tension springs fixedly connected to the fixed supports. The two fixed supports are fixedly connected to the discharge port. The discharge port is fixedly connected to the housing.

[0009] Furthermore, it also includes a transmission assembly, which comprises two rotating cams, two cam fixing rods, two friction wheels, two double flywheels, two sets of transmission belt one, a single flywheel, and two sets of transmission belt two. The friction wheels are rotatably connected to the transmission rods. The friction wheels are slidably connected to the rotating cams. The rotating cams are coaxially rotatably connected to the cam fixing rods and are connected to the double flywheels via transmission belt one. The double flywheels are connected to the single flywheel via transmission belt two.

[0010] Furthermore, it also includes a motor, a material-feeding gear, a material-feeding drive shaft, and a single flywheel that is coaxially and fixedly connected to the material-feeding drive shaft. One end of the material-feeding drive shaft is coaxially and fixedly connected to the drive shaft of the motor, and the other end is coaxially and fixedly connected to the material-feeding gear.

[0011] Furthermore, it also includes a feed inlet, the top of which is fixedly connected to the top of the box body, and the bottom of which is fixedly connected to the inner wall of the box body. The feeding gear is located at the center of the bottom slot of the feed inlet and is rotatably connected to it through the feeding drive shaft.

[0012] Furthermore, it also includes an exhaust door, which is rotatably connected to the housing.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. This utility model uses a motor to drive the material feeding gear to rotate, and at the same time, the motor drives the single flywheel to rotate, which in turn drives the double flywheel to rotate via a second transmission belt. Furthermore, through the meshing longitudinal and transverse bevel gears, the rotating cone is driven to rotate. The double flywheel drives the rotating cam to rotate via a first transmission belt, which in turn drives the vibrating screen to vibrate back and forth via a transmission rod, achieving integrated control and easy operation.

[0014] 2. This utility model uses a feeding gear to feed low-density fibrous materials into the box, where they are then dispersed by a rotating cone and evenly sprinkled onto the vibrating screen. Driven by a motor, the vibrating screen continuously reciprocates, accelerating the material's passage through the screen holes and into the discharge port. This further reduces the risk of material clumping and clogging, decreases the frequency of manual intervention, saves labor costs, and improves the efficiency and stability of the feeder.

[0015] 3. This utility model uses the back-and-forth oscillation of the vibrating screen to screen out a large amount of materials that meet the size requirements from the box, while also retaining a small amount of materials that are too large or do not meet the requirements, thus avoiding impact on downstream production and saving the cost of manual screening. At the same time, when the motor stops working, the vibrating screen will move to one end under the action of the tension spring, so that the holes on the vibrating screen and the holes at the bottom of the box are just offset to form a closed state. Even if the material accumulated in the feed inlet leaks into the box, it will not leak out of the box and cause waste. Attached Figure Description

[0020] 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 protection scope of the present utility model.

[0021] It should be noted that when a component is said to be "installed on" another component, it can be directly on the other component or it may be in a component that is centered on it. When a component is said to be "set on" another component, it can be directly set on the other component or it may also be in a component that is centered on it. When a component is said to be "fixed to" another component, it can be directly fixed to the other component or it may also be in a component that is centered on it.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "or / and" as used herein includes any and all combinations of one or more of the associated listed items.

[0023] Example: Please see Figures 1-10 This embodiment provides a dedicated feeder for low-density fibrous materials, including a discharge port 1, fixed supports 2, and a housing 3. The lower end of the discharge port 1 is directly connected to downstream equipment, and the housing 3 is fixedly connected to the discharge port 1 to form a whole. Two fixed supports 2 are symmetrically fixedly connected to both sides of the discharge port 1 and are parallel to the sides of the housing 3.

[0024] The vibrating and dispersing assembly 5 includes a vibrating screen 501, four vibrating slides 502, a traction rod 503, two tension springs 504, and two transmission rods 505. The four vibrating slides 502 are fixedly connected to the bottom of the housing 3, with two at the front and two at the back, symmetrically distributed. Each end of the vibrating screen 501 has two sliding protrusions that engage within the vibrating slides 502, allowing the vibrating screen 501 to slide smoothly against the slides. The traction rod 503 is fixedly connected to the vibrating screen 501 in the middle, and its two ends are slidably connected to two fixed supports 2. A slot is provided at the connection point between the fixed support 2 and the traction rod, allowing the two ends of the traction rod to slide back and forth within the slot. One end of each of the two tension springs 504 is fixedly connected to a protrusion on one of the two fixed supports 2, and the other end is fixedly connected to both ends of the traction rod 503. The two transmission rods 505 are fixedly connected to both ends of the traction rod 503.

[0025] The bottom of the housing 3 has evenly distributed screening holes with a diameter of about 1 cm. On the front and back of the housing 3, about 2 mm above the bottom, there are through guide grooves on both sides. The vibrating screen 501 slides through the guide grooves and connects to the vibrating slide 502. The length of the vibrating slide 502 exceeds the maximum distance that the vibrating screen 501 can swing in one direction, effectively ensuring that the vibrating screen 501 will not derail, thus improving the stability and reliability of this invention. The surface of the vibrating screen 501 also has screening holes of the same size and evenly distributed as the bottom of the housing 3. When the vibrating screen 501 reciprocates within the guide grooves, the screening holes on the bottom of the vibrating screen 501 and the housing 3 can open and close periodically. A discharge door 9 is provided on the housing 3 above the vibrating screen 501.

[0026] The traction rod 503 drives the vibrating screen 501 to vibrate back and forth, keeping the low-density fibrous material in a constant state of motion, thus reducing static accumulation. During the vibration process, materials of suitable size can pass through the housing 3 more quickly and be discharged rapidly from the outlet 1. In other embodiments, the size and spacing of the screening holes at the bottom of the vibrating screen 501 and the housing 3 can be designed to accommodate different sizes and types of low-density fibrous materials, thereby achieving better working results. For materials with specific size requirements, the vibrating screen 501 can also play a screening role, intercepting a small amount of material exceeding the size requirements, saving on manual screening costs. When the excess material accumulates to a certain extent, it can be discharged from the housing 3 through the opening of the discharge door 9.

[0027] The vibrating and dispersing assembly 5 also includes a rotating cone 506, a cone fixing frame 507, a longitudinal bevel gear 508, and a transverse bevel gear 509. The rotating cone 506 is rotatably connected to the cone fixing frame 507. The cone fixing frame 507 is fixedly connected to the inner wall of the housing 3. The bottom of the rotating cone 506 is coaxially fixedly connected to the transverse bevel gear 509. The transverse bevel gear 509 meshes with the longitudinal bevel gear 508. The surface of the rotating cone 506 has a slightly raised spiral curve. When the rotating cone 506 rotates, it can disperse the low-density fibrous material entering the housing 3 and evenly sprinkle it onto the vibrating screen 501, reducing the possibility of material accumulation and improving the stability of this invention.

[0028] In other embodiments, depending on the size and type of the low-density fibrous material, the spiral curve on the surface of the rotating cone 506 can be replaced with other curves or protrusions to improve the dispersing effect. The rotating cone 506 can also be made hollow inside to reduce the weight of the cone and make it more energy-efficient and environmentally friendly.

[0029] It also includes a motor 10, a feed inlet 8, a material-feeding gear 6, and a material-feeding drive shaft 7. The motor 10 is fixedly connected to the fixed bracket 2. The top of the feed inlet 8 is fixedly connected to the top of the housing 3, and the bottom of the feed inlet 8 has two fixed rods fixedly connected to the housing 3. A through slot is opened in the center of the bottom of the feed inlet 8, and the material-feeding gear 6 is located in the center of the slot and rotatably connected to the feed inlet 8. The material-feeding gear 6 is coaxially fixedly connected to the material-feeding drive shaft 7. One end of the material-feeding drive shaft 7 is rotatably connected to the housing 3, and the other end is coaxially fixedly connected to the drive shaft of the motor 10. The motor 10 drives the rotation of the material-feeding gear 6, which can actively feed the low-density fibrous material in the feed inlet 8 into the housing 3, thus avoiding the situation where the low-density fibrous material easily clumps together and clogs the feed inlet 8. The motor 10 drive improves both working efficiency and the stability of the feeder. The tooth profile of the feed gear 6 is specifically designed to feed low-density fibrous materials into the housing 3 without damaging the materials. In other embodiments, feed gears 6 with different tooth profiles can be selected depending on the material to achieve better working results.

[0030] The system also includes a transmission assembly 4, which comprises two rotating cams 401, two cam fixing rods 402, two friction wheels 403, two double flywheels 404, a flywheel drive shaft 405, a single flywheel 406, and two sets of transmission belts 407 and 408. The single flywheel 406 is coaxially and fixedly connected to the drive shaft of the motor 10. The double flywheels 404 are coaxially and fixedly connected to the flywheel drive shaft 405. The single flywheel 406 and the double flywheels 404 are connected by the second transmission belt 408. The rotating cams 401 are fixedly connected to the cam fixing rods 402. One end of the cam fixing rod 402 is fixedly connected to the discharge port 1, and the other end is fixedly connected to the fixed bracket 2. The rotating cams 401 and the double flywheels 404 are connected by the first transmission belt 407. The rotating cams 401 are slidably connected to the friction wheels 403. The friction wheels 403 are rotatably connected to the transmission rod 505 in the vibrating and dispersing assembly 5. The rotary cam 401 consists of a single flywheel and an elliptical cam. The distance between the major and minor axes of the ellipse is moderate, which can satisfy the reciprocating oscillation of the vibrating screen 501 without interfering with the normal operation of the system. Except for the single flywheel 406 and the transmission belt 408, the other transmission components 4 are symmetrically arranged on both sides of the housing 3.

[0031] In summary, motor 10 drives the material-feeding gear 6 to rotate, feeding low-density fibrous material into the housing 3. Motor 10, through transmission belt 2 408, double flywheels 404, and meshing bevel gears, drives the rotating cone 506 to rotate, dispersing the material fed into the housing 3 and evenly distributing it onto the vibrating screen 501. Motor 10, through transmission belt 1 407, rotating cam 401, friction wheel 403, and transmission rod 505, drives the vibrating screen 501 to vibrate back and forth, shaking the evenly distributed low-density fibrous material out of the housing 3 and into the discharge port 1. This achieves the linkage of the entire feeder, greatly reducing the "clumping" and accumulation of material from the inlet 8 to the outlet 1 during the entire process, avoiding blockages, and improving the practical stability and reliability of this invention. In other embodiments, depending on actual needs, the flywheel can be replaced with a gear, and the belt can be replaced with a chain, thereby achieving more precise linkage.

[0032] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0033] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
