Description

Technical Field

[0001] This utility model belongs to the technical field of quantitative feeders, and in particular relates to an adjustable quantitative feeder. Background Technology

[0002] Quantitative feeders are key automated equipment in industrial production lines, ensuring precise and controllable conveying volume. They are suitable for various material types such as granules and powders, and are widely used in industries such as building materials, chemicals, coal, and metallurgy due to their high control precision, providing support for stable and efficient production processes and material consumption control.

[0003] Existing quantitative feeders have some drawbacks in use, such as the possibility that material may accumulate into a cone shape during feeding. Excess material at the top of the cone may fall to the ground during transportation, and this fallen material cannot be recovered. This can lead to significant losses, especially for high-value materials, due to long-term accumulation. Therefore, we propose an adjustable quantitative feeder. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable quantitative feeder to solve the problems mentioned in the background art.

[0005] In view of this, the present invention provides an adjustable quantitative feeder, including a housing, and further comprising:

[0006] Two rotating plates are rotatably mounted inside the housing. A power cavity is provided inside the housing and on one side of the rotating plates. One end of each of the two rotating plates passes through the housing and extends into the power cavity. A gear is fixedly mounted on one end of each of the two rotating plates.

[0007] A drive assembly, located within the housing, is used to drive two gears to rotate;

[0008] A sliding groove is formed inside the housing. A scraper is slidably installed inside the sliding groove. A storage box is inserted and installed inside the housing and below the rotating plate. A collection box is inserted and installed inside the housing and on one side of the storage box.

[0009] A power assembly, located within the housing, is used to drive the scraper to slide.

[0010] In this technical solution, when feeding is required, the drive component can be set to drive the two gears meshing with it to rotate. The two gears drive the two rotating plates to rotate downwards, thereby controlling the feeding speed of the material in the shell. After feeding is completed, the two rotating plates rotate upwards and reset, and the material is no longer fed.

[0011] The power component can drive the scraper to slide in the sliding groove to scrape the material in the storage box. The collection box is used to receive the scraped material, and the limit plate is inserted into the collection box to ensure its stable installation.

[0012] In the above technical solution, the driving component further includes:

[0013] A cylinder is fixedly installed in the power chamber. A sliding plate is fixedly installed on the telescopic end of the cylinder. A rack is fixedly installed on both sides of the sliding plate. The two racks are located on one side of two gears and mesh with the two gears respectively.

[0014] In this technical solution, when feeding is required, the cylinder is first started and the sliding plate is driven to slide. The sliding plate drives the two racks to move, and the two racks drive the two gears meshing with them to rotate. The two gears drive the two rotating plates to rotate downwards, thereby controlling the feeding speed of the material in the shell. After feeding is completed, the two rotating plates rotate upwards and reset, and the material is no longer fed.

[0015] In the above technical solution, the power component further includes:

[0016] A rotating column is disposed in a sliding groove. Two connecting rods are rotatably mounted on the rotating column. A first sliding block and a second sliding block are rotatably mounted at both ends of the connecting rods, respectively. One of the first sliding blocks and one of the second sliding blocks are slidably connected to the scraper, and the other of the first sliding block and the other of the second sliding block are slidably connected to the sliding groove.

[0017] The motor is fixedly mounted on the housing. The output shaft of the motor extends through the housing into the sliding groove. A threaded rod is fixedly mounted on the output shaft of the motor. One end of the threaded rod passes through another first sliding block and another second sliding block. The threaded rod has two sections of threads with opposite directions, and the threaded rod is threadedly connected to the other first sliding block and the other second sliding block.

[0018] In this technical solution, the motor is then started and the threaded rod is driven to rotate. Under the action of the thread, the threaded rod drives one of the second sliding blocks and one of the first sliding blocks to move. Through the cooperation of the connecting rod and the rotating column, the scraper is driven to slide in the sliding groove to scrape the material in the storage box. The collection box is used to receive the scraped material. The limiting plate is inserted into the collection box to ensure its stable installation.

[0019] In the above technical solution, two guide rods are fixedly installed in the sliding groove, and one end of each guide rod passes through the scraper. The scraper is slidably connected to the two guide rods.

[0020] In this technical solution, it is ensured that the scraper can slide stably along the guide rod within the sliding groove.

[0021] In the above technical solution, the output shaft of the motor is rotatably connected to the housing and the sliding groove, the threaded rod is rotatably connected to the sliding groove, the sliding plate and the two racks are slidably connected to the power cavity, and the two gears are rotatably connected to the power cavity.

[0022] In this technical solution, it is ensured that the output shaft of the motor can rotate within the housing and the sliding groove, that the threaded rod can rotate within the sliding groove, that the sliding plate and the two racks can slide within the power cavity, and that the two gears can rotate within the power cavity.

[0023] In the above technical solution, a limiting groove is further provided inside the housing and at the top of the collection box. A limiting plate is slidably installed in the limiting groove. The lower end of the limiting plate passes through the limiting groove and extends into the collection box. The limiting plate is inserted into the collection box.

[0024] In this technical solution, the limiting plate and the collection box are connected to ensure stable installation.

[0025] In the above technical solution, the top of the storage box is in close contact with the housing and the scraper.

[0026] In this technical solution, it is ensured that the scraper can level the material inside the storage box.

[0027] The beneficial effects of this utility model are:

[0028] This adjustable quantitative feeder, when feeding is required, drives two meshing gears to rotate via a drive assembly. These gears then drive two rotating plates to rotate downwards, thereby controlling the feeding speed of the material inside the housing. After feeding is complete, the two rotating plates rotate upwards and reset, at which point feeding stops. A power assembly then drives a scraper to slide within a sliding groove, leveling the material in the storage box. The collection box is used to receive the scraped material, ensuring that it does not fall into the outside during transportation. Attached Figure Description
