Description

Technical Field

[0001] The utility model belongs to the technical field of scraper conveyors, and more specifically, it particularly relates to a scraper conveyor with anti-overflow scrapers. Background Art

[0002] Scraper conveyor series products are widely applicable to industries and departments such as metallurgy, building materials, electric power, chemical industry, cement, ports, docks, coal, mines, grain and oil, food, feed, etc. A scraper conveyor is a continuous transportation device that conveys bulk materials in a closed rectangular cross-section housing by means of a moving scraper chain; since the scraper chain is completely buried in the materials during material transportation, it is called a scraper conveyor.

[0003] After retrieval, for example, the patent with the patent number CN219585114U discloses a device for preventing overfeeding of a scraper conveyor to solve the technical problems that the conveying chain of the current scraper conveyor will carry materials forward, and the materials cannot be completely unloaded at the designated position, resulting in material mixing or material accumulation at the front end of the scraper conveyor and even blocking the machine. This device is installed in the scraper conveyor. In the scraper conveyor above the middle discharge port of the scraper conveyor, a pressure wheel is provided. The pressure wheel is located between two upper and lower chains in the scraper conveyor. The pressure wheel is provided with pressure teeth that can engage with the chain in the scraper conveyor. After the pressure teeth engage with the chain, the residual materials on the chain can be pressed down into the lower middle discharge port.

[0004] The scraper conveyor in the above patent still has the following deficiencies:

[0005] In the above patent, the meshing action of the pressure wheel and the chain is used to clean and discharge the materials that may be stuck in the chain. When the material particles are relatively large, it can play a certain role in preventing overfeeding. However, during the feeding process of relatively fine feed particles and other materials, simply squeezing cannot completely clean the materials, and even may cause the materials to accumulate on the chain, increasing the running resistance of the chain and being unfavorable to the normal operation of the equipment. Therefore, it has certain limitations. Summary of the Utility Model

[0006] In order to solve the above technical problems, the utility model provides a scraper conveyor with anti-overflow scrapers to solve the problem that during the feeding process of relatively fine feed particles and other materials as mentioned in the above background art, simply squeezing cannot completely clean the materials, and even may cause the materials to accumulate on the chain, increasing the running resistance of the chain and being unfavorable to the normal operation of the equipment. Therefore, it has certain limitations.

[0007] The purpose and efficacy of the scraper conveyor with anti-overflow scrapers of the utility model are achieved by the following specific technical means:

[0008] A scraper machine with an anti-overflow scraper comprises: a feeding trough; the feeding trough adopts a rectangular groove structure, and a group of rectangular through-groove structures are opened on the front and rear sides of the top of the feeding trough, and a penetrating circular through-groove structure is opened on one side of the feeding trough; a group of connecting plates with rectangular plate structures are correspondingly arranged on the top of the rectangular through-groove of the feeding trough, and a penetrating circular through-groove structure is opened on one side of the top of the connecting plate, and a penetrating screw hole structure is opened on the left side of the top of the connecting plate; a sliding rod with a cylindrical structure is slidably arranged in the circular through-groove on one side of the top of the connecting plate; a fixing plate with a U-shaped plate structure is fixedly arranged at the bottom of the sliding rod; a cleaning roller with a cylindrical structure is rotatably arranged at the bottom of the fixing plate, a cleaning brush structure is arranged on the outside of the cleaning roller, and a power source is arranged inside the cleaning roller.

[0009] Furthermore, a chain is rotatably arranged on the outer side of the feeding chute; scrapers with rectangular plate structures are equidistantly arranged and fixed on the outer side of the chain; a group of slide rails are fixedly arranged on both sides of the bottom of the rectangular through groove of the feeding chute; a baffle with a rectangular plate structure is slidably arranged between the two groups of slide rails, and a through-type screw hole structure is opened on the rear side of the baffle.

[0010] Furthermore, a lead screw is rotatably arranged between the two groups of slide rails, and the lead screw is connected to the baffle plate through threaded cooperation; a first motor is fixedly arranged at the bottom of the loading chute, and the first motor is transmission-connected to the lead screw.

[0011] Furthermore, a knocking rod with a cylindrical structure is slidably arranged in the circular through groove on one side of the feeding trough, and a spring is sleeved on the outer side of the knocking rod; a mounting plate with a U-shaped plate structure is fixedly arranged at the right end between the two groups of knocking rods; two groups of second motors are fixedly arranged on the right side of the feeding trough; a cam is provided on one side of the second motor in a transmission connection, and the cam is in contact with the mounting plate.

[0012] Furthermore, a screw is rotated on the top of the fixing plate, and the screw is connected to the screw hole of the connecting plate through threaded matching.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] In the present application, by providing a connecting plate, a fixed plate and a cleaning roller, the height of the cleaning roller can be adjusted so that the cleaning roller can maintain contact with the chain and the scraper, so that the residual material on the chain and the scraper can be continuously cleaned through the rotation of the cleaning roller, and relatively fine particles and some larger material particles can be completely cleaned away by the cleaning roller, thereby achieving the function of preventing material overflow.

[0015] If some of the materials are in a granular or fragmented structure and are likely to get stuck on the chain, the inner end of the knocking rod can continuously knock and vibrate the chain, so that the stuck granular fragments can quickly fall off, thereby further completing the cleaning process of different materials, avoiding the phenomenon of incomplete discharging and material overflow, preventing the mixing of different materials, improving the discharging effect, and at the same time meeting the anti-overflow requirements of different types of materials, thus enhancing the practicality of this device.
