Description

Technical Field

[0001] The utility model relates to the technical field of concrete production, in particular to a special concrete raw material conveying device. Background Art

[0002] Special concrete refers to cement concrete with special uses made from new materials, industrial waste or new processes, such as lightweight aggregate concrete, fiber-reinforced concrete, polymer concrete, etc. Lightweight aggregate concrete refers to concrete made with lightweight aggregate. Lightweight aggregate concrete has the characteristics of light weight, high strength, thermal insulation and fire resistance. Lightweight aggregate is used to reduce the mass of concrete and improve thermal performance. Lightweight aggregate is generally ceramsite, which is ceramic particles. The appearance of ceramsite is mostly round or oval, with a ceramic shell on the surface and a honeycomb interior. When producing concrete, it is necessary to use a conveyor belt to transport various raw materials to a high-rise mixer for mixing;

[0003] Application No. 202320137124.9 discloses a special concrete raw material conveying device, "under the drive of the motor, under the transmission action of the second rotating rod, the second active bevel gear, the second driven bevel gear, the first rotating rod, the first active bevel gear, and the first driven bevel gear, the stirring rod stirs the expanded clay on the screen, so that the expanded clay is spread more evenly, thereby improving the screening effect." In the above, the situation where raw materials accumulate on the conveyor belt is solved by rotating the stirring rod, but when the stirring rod rotates, the raw materials move to the left and right on the conveyor belt with the rotation, so that part of the raw materials are transported from the side of the conveyor belt to the processing equipment, which may easily cause the raw materials to be unable to be accurately transported to the processing equipment, resulting in poor conveying effect. In addition, the thrust generated during rotation may easily cause individual raw materials to bounce out from the outer edge of the conveyor belt, and the bounced raw materials may easily hit the operator, and the raw materials that bounce out and fall to the ground need to be cleaned, affecting the cleanliness of the conveying device during the conveying process. Utility Model Content

[0004] The purpose of this utility model is to provide a special concrete raw material conveying device to solve the above-mentioned shortcomings in the technology.

[0005] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a special concrete raw material conveying device, comprising a bearing seat, wherein two rollers are movably connected in the mounting cavity of the bearing seat, a conveyor belt is sleeved on the outside of the two rollers, a plurality of holes are equidistant and evenly provided on the outer wall of the conveyor belt, a through groove is provided on the lower end surface of the bearing seat, a support frame is fixedly connected to the lower end surface of the bearing seat, and a discharge inclined plate is fixedly connected to the discharge end of the bearing seat.

[0006] A drive assembly is provided on the supporting seat, and the drive assembly includes a first drive motor and a belt. The first drive motor is fixedly connected to one side of the outer wall of the supporting seat, and the belt is sleeved on a connecting groove opened on the outside of one end of the two rollers. The output end of the first drive motor is connected to one end of one of the rollers.

[0007] Specifically, during transportation, the raw materials are first placed on the conveyor belt, and then the first drive motor is turned on. One of the rollers is driven to rotate by the first drive motor, and at this time the other roller is rotated by the belt. This operation can realize the operation of the conveyor belt, so that the raw materials are transported from one end of the conveyor belt to the other end of the conveyor belt, and finally the raw materials are discharged into the processing equipment through the discharge inclined plate. In addition, during the transportation process, the conveyor belt is provided with holes, so that the damaged raw materials pass through the conveyor belt through the holes, and finally enter the receiving container through the through slot. This operation can screen out damaged raw materials during the transportation process.

[0008] Preferably, a material guiding structure is provided at the upper end of the supporting seat, and the material guiding structure includes a material box, a feeding hopper, a second driving motor, a rotating rod, three partitions and two fixed seats, the two fixed seats are symmetrically fixedly connected to the upper end surface of the supporting seat, the material box is connected between the two fixed seats, and the feeding hopper is connected to the middle position of the upper end surface of the material box.

[0009] Preferably, the second drive motor is fixedly connected to one side of the outer wall of the material box, the rotating rod is movably connected to the inside of the material box, the three partitions are fixedly connected to the outer wall of the rotating rod at equal distances, and one end of the rotating rod passes through the material box and is connected to the output end of the second drive motor.

The second driving motor drives the rotating rod to rotate, so that the partition rotates as the rotating rod rotates. After the raw materials in the storage box enter the material box through the feeding hopper, they fall between the two partitions. Finally, as the partition rotates, they are delivered to the discharge channel opened in the material box. This operation can deliver the raw materials to the end of the conveyor belt in batches and in an orderly manner, effectively reducing the amount of raw materials accumulated on the conveyor belt, avoiding the situation where the raw materials are crowded on the conveyor belt due to excessive accumulation, which makes it easy for some raw materials to slip from the outer edge during transportation, and ensures the stability of the raw materials conveyed on the conveyor belt.

[0015] Through the above technical solution:

[0016] During the transportation of raw materials on the conveyor belt, the cross bar movably connected by the movable groove and the connecting short rod can block and weaken the transportation speed of the raw materials, which can effectively slow down the transportation speed of the raw materials and avoid the situation where damaged raw materials are transported to the processing equipment along with the intact raw materials due to excessive transportation speed. In addition, the raw materials can also be evenly transported on the conveyor belt, avoiding the situation where the raw materials deviate to the outer edge of the conveyor belt during transportation, and preventing individual raw materials from jumping out of the outer edge of the conveyor belt and causing the disadvantage of easily hitting the operator, thereby ensuring the neatness of the conveying device during transportation.

[0017] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0018] 1. By setting up the material guide structure, the conveying device has the material guide function of raw material unloading. During transportation, the raw materials can be put into the conveyor belt in batches and in an orderly manner, effectively reducing the amount of raw materials piled up on the conveyor belt, avoiding the situation where the raw materials are crowded on the conveyor belt due to excessive accumulation, which causes some raw materials to easily slide from the outer edge during transportation. It ensures the stability of raw materials on the conveyor belt, so that the raw materials can be fully transported to the processing equipment. In addition, it also prevents the disadvantage of damaged raw materials that cannot be screened out due to raw material accumulation, ensuring the quality of raw materials transported to the processing equipment;

[0019] 2. By setting up a slowing-down structure, the material guiding structure can have the function of slowing down the conveying speed of raw materials. During the conveying process, the conveying speed of raw materials can be blocked and weakened, which can effectively slow down the conveying speed of raw materials and avoid the situation where damaged raw materials are conveyed to the processing equipment along with intact raw materials due to excessive conveying speed. In addition, the raw materials can also be evenly conveyed on the conveyor belt, ensuring that the raw materials are in the middle position during transportation, avoiding the situation where the raw materials are offset to the outer edge of the conveyor belt during transportation, and avoiding the disadvantage that individual raw materials jump out from the outer edge of the conveyor belt and easily hit the operator, and also eliminating the subsequent process of cleaning the raw materials that fall to the ground, ensuring the cleanliness of the conveying device during transportation.
