Description

Technical Field

[0001] This utility model relates to the field of hoppers, specifically a feed hopper for a crusher with anti-clogging function. Background Technology

[0002] The main function of a hopper is as an auxiliary device in a conveying system. Its primary role is to ensure the continuity and efficiency of material conveying. Hoppers play a crucial role in conveying systems, not only for storing and conveying various materials, but also for optimizing material flow and conveying efficiency through their specific design. They are widely used in chemical, building materials, crusher, and machinery manufacturing industries.

[0003] Application number CN219114473U discloses a feeding hopper, including a funnel area and a storage area. The funnel area is larger at the top and smaller at the bottom, with a gradually narrowing slope at the bottom to facilitate material feeding. The storage area is a rectangular frame composed of four retractable side panels. The storage area is movably positioned above the funnel area to accommodate more material. This invention allows for modification of the feeding hopper structure by shortening or raising the height of the storage area, or by removing it, according to production requirements. It adapts to different packaging sizes of materials without requiring replacement of the feeding hopper, offering strong adaptability, facilitating production, and improving production efficiency.

[0004] In existing technology, the feeding hopper is divided into a funnel area and a storage area. The funnel area is large at the top and small at the bottom, which facilitates the feeding effect. However, during use, the material accumulates at the bottom and is prone to blockage, which affects the feeding operation. The structure of the feeding hopper can be changed by shortening or raising the height of the storage area, or by removing it, to adapt to different sizes of material packaging. During the feeding process, the material moves around and is prone to vibration, resulting in insufficient overall stability of the feeding hopper and affecting the feeding and conveying effect. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a feed hopper for a pulverizer with anti-clogging features, comprising a main body, which includes a storage structure, a shock-absorbing component, and a stirring mechanism. The storage structure has a storage box on its exterior, a connecting plate on the top of the storage box, and a vibration spring and fixing bolts installed at the bottom of the connecting plate. The shock-absorbing component has a connecting plate on its exterior, a connecting block on one side of the connecting plate, and a shock-absorbing rubber block and a funnel box installed at the bottom of the connecting block. The stirring mechanism has a rotating shaft on its exterior, a scraper plate on the top of the rotating shaft, a fixing clamp plate fitted over the rotating shaft, connecting rods installed on both sides inside the fixing clamp plate, and material-pulling plates installed on both sides outside the connecting rods.

[0007] The shock absorption components are installed. By placing shock-absorbing rubber blocks at the bottom of the storage bin, the vibration generated by the feeding hopper when conveying materials is gradually weakened by the shock-absorbing rubber blocks, thereby reducing the vibration and improving the overall stability of the feeding hopper.

[0008] In addition, a stirring mechanism is set up, and a vibration spring is set up in conjunction with an external motor to make the bottom of the storage box vibrate, which agitates the material inside and prevents the material from clumping together. By setting up a stirring mechanism at the bottom of the funnel box, the rotating shaft drives the material-pulling plate outside the fixed clamp to move, so that the material inside does not stand still in the same position and accumulate, causing blockage. This achieves the function of preventing material blockage and thus improves the working efficiency of the feeding hopper.

[0009] Furthermore, the storage box is a circular box, the connecting plate is a circular through plate and is adapted to be connected to the top of the storage box, the connecting plate has a circular opening inside, the opening has several groups and is distributed in a circumferential array, the vibration spring has four groups and has a matching fixing bolt on the top, the fixing bolt is adapted to be connected to the opening, and a limiting plate is installed at the bottom of the vibration spring.

[0010] Furthermore, the connecting plate is an arc-shaped plate and has several sets, the connecting block is an arc-shaped plate and is adapted to be connected to the side of the connecting plate, the shock-absorbing rubber block has several sets, all of which are cylindrical and are connected to the center of the connecting block, and the bottom of the connecting plate is provided with a funnel box.

[0011] Furthermore, the rotating shaft is cylindrical and connected to the center of the bottom of the funnel box; the anti-scratching plate is a cross-shaped plate and its bottom is connected to the top of the rotating shaft; the fixing clamp has three sets of square plates distributed in a straight line at equal intervals; the connecting rod has three sets of arc-shaped plates distributed in a circumferential array; and the material feeding plate is externally adapted to the connecting rod.

[0012] Furthermore, a motor is installed on one side of the limiting plate, and an electrical board is provided at the bottom of the motor. The electrical board is square and connected to the inside of the storage box.

[0013] Furthermore, the limiting plate has four sets of arc-shaped plates that are attached to the outside of the storage box, and the limiting plates are arranged in a circumferential array.

[0014] Furthermore, the funnel box is a circular box with a through hole at the bottom, and the through hole is circular and extends to the bottom of the funnel box.

[0015] This utility model has the following beneficial effects:

[0016] (1) This utility model: a shock-absorbing component is provided. By setting shock-absorbing rubber blocks at the bottom of the storage box, the vibration generated by the feeding hopper when conveying materials is gradually weakened by the shock-absorbing rubber blocks, thereby improving the overall stability of the feeding hopper.

[0017] (2) This utility model: A stirring mechanism is set up, and a vibration spring is set up to work with an external motor to make the bottom of the storage box vibrate, which agitates the internal material to avoid the material from clumping together. By setting a stirring mechanism at the bottom of the funnel box, the rotating shaft drives the material-pulling plate outside the fixed clamp to move through rotation, so that the internal material is not fixed in the same position to form a pile and cause blockage, thereby achieving the function of preventing material blockage and improving the working efficiency of the feeding hopper.

The top of the rotating shaft 301 is provided with an anti-scratching plate 302. The rotating shaft 301 is fitted with a fixing clamp 303. The two sides inside the fixing clamp 303 are equipped with connecting rods 304. The two sides outside the connecting rods 304 are equipped with material-pulling plates 305.

[0029] The shock absorption component 2 is set up. By setting shock absorption rubber blocks 203 at the bottom of the storage box 101, the vibration generated by the feeding hopper when conveying materials is gradually weakened by the shock absorption rubber blocks 203, thereby reducing the vibration and improving the overall stability of the feeding hopper.

[0030] Additionally, a stirring mechanism 3 is provided, and a vibration spring 103, in conjunction with an external motor 106, causes the bottom of the storage box 101 to vibrate, agitating the internal materials to prevent them from clumping together. By setting the stirring mechanism 3 at the bottom of the funnel box 204, the rotating shaft 301 drives the material-pushing plate 305 outside the fixed clamping plate 303 to move through rotation, preventing the internal materials from being fixed in the same position and accumulating, thus achieving the function of preventing material blockage and improving the working efficiency of the feeding hopper.

[0031] The storage box 101 is a circular box, the connecting plate 102 is a circular through plate and is adapted to be connected to the top of the storage box 101, the connecting plate 102 has a circular through opening inside, the through opening has several sets and is distributed in a circumferential array, the vibration spring 103 has four sets and the top is provided with a matching fixing bolt 104, the fixing bolt 104 is adapted to be connected to the through opening, and the bottom of the vibration spring 103 is equipped with a limiting plate 105.

[0032] The connecting plate 201 is an arc-shaped plate and has several sets. The connecting block 202 is an arc-shaped plate and is adapted to be connected to the side of the connecting plate 201. The shock-absorbing rubber block 203 has several sets, all of which are cylindrical and are connected to the center of the connecting block 202. The bottom of the connecting plate 201 is provided with a funnel box 204.

[0033] The rotating shaft 301 is cylindrical and connected to the center of the bottom of the funnel box 204. The anti-scratching plate 302 is a cross-shaped plate and its bottom is connected to the top of the rotating shaft 301. The fixed clamping plate 303 has three sets of square plates that are distributed in a straight line at equal intervals. The connecting rod 304 has three sets of arc plates that are distributed in a circular array. The material feeding plate 305 is externally adapted and connected to the connecting rod 304.

[0034] A motor 106 is installed on one side of the limiting plate 105. The bottom of the motor 106 is equipped with an electric plate, which is square and connected to the inside of the storage box 101.

[0035] The limiting plate 105 has four sets of arc-shaped plates that are attached to the outside of the storage box 101. The limiting plate 105 is arranged in a circular array.

[0036] The funnel box 204 is a circular box with a through hole at the bottom. The through hole is circular and extends to the bottom of the funnel box 204.

[0037] Working principle: During use, material is placed in the storage box 101 in the storage structure 1. The material gradually descends into the funnel box 204 at the bottom. The vibration spring 103 on the outside of the storage box 101, in conjunction with the motor 106, causes a small vibration at the bottom of the box, which makes the material inside evenly distributed and avoids clumping. The bottom of the storage structure 1 is equipped with a shock-absorbing component 2 and a shock-absorbing rubber block 203 to reduce the vibration when the material inside slides down, thereby enhancing the overall stability of the feeding hopper. A rotating shaft 301 is located at the center of the bottom of the funnel box 204. The rotation of the rotating shaft 301 drives the external material-pushing plate 305 to rotate and move, which stirs the material inside and prevents clogging. The material flows out through the through hole at the bottom of the funnel box 204 for transmission.
