Technical Field
[0001] The invention relates to the technical field of screw feeders, and in particular to a dust-proof and leakage-proof screw feeder. Background Art
[0002] Automatic spiral feeder is mainly used for feeding powder and granular materials, and is suitable for feeding equipment with certain high requirements in industries such as food, chemical, building materials, plastics and packaging.
[0003] During use, the existing spiral feeder usually sets the bearing connected to the bottom end of the conveying screw on the outside of the bottom end of the conveying pipe, which makes it easy for dust to enter during operation, not only affecting the performance of the equipment and resulting in poor feeding effect, but also requiring frequent cleaning and maintenance, resulting in low performance. In addition, during use, the existing spiral feeder requires manual injection of materials into the material box, and the material box is usually an open structure, which causes the dust generated by the material during the injection process to spread around the equipment, which on the one hand affects the air quality of the workshop, and on the other hand easily causes discomfort to the workers, resulting in low environmental performance. Therefore, there is an urgent need for a dust-proof and leakage-proof spiral feeder to solve the above problems. Summary of the invention
[0004] The purpose of the present invention is to provide a dust-proof and leakage-proof spiral feeder in order to solve the above-mentioned problems.

[0007] Furthermore, the material guide pipe is formed at the bottom end of the material box, the conveying pipe is fixed to the bottom end of the material guide pipe by bolts, and the discharge pipe is formed on the conveying pipe.
[0008] By adopting the above technical solution, the material in the material box flows into the conveying pipe through the material guide pipe, and the material after being lifted and conveyed by the conveying pipe is discharged through the discharge pipe, thereby realizing the loading of the material.
[0009] Furthermore, the conveying motor is fixed to the conveying pipe via a bracket, and the output shaft of the conveying motor is fixedly connected to the driving gear.
[0010] By adopting the above technical solution, the conveying motor provides power to the driving gear to rotate.
[0011] Furthermore, the transmission gear is rotatably mounted on the top end of the conveying pipe, and the synchronous belt is meshed with both the driving gear and the transmission gear.

[0014] By adopting the above technical solution, the transmission gear drives the screw to rotate, and then the screw lifts and conveys the material in the conveying pipe to realize the loading of the material, and in the loading process, since the bearing and the gasket are designed inside the bearing seat, and the dust-proof and leakage-proof cover is sleeved on the outer side of the bearing and the gasket, the dust-proof and leakage-proof cover hides them to prevent dust and leakage. No matter how the machine runs, dust cannot affect the bearing, so the device can continuously and efficiently load materials, thereby improving the use effect of the device.

[0023] Furthermore, an air storage tank is installed on one side wall of the dust removal cylinder, two groups of air pipes are led out of the air storage tank, and electric valves are installed on the air pipes.
[0024] By adopting the above technical solution, the gas storage tank can ensure the stability of the air pressure in the material box through the air pipe, and the electric valve controls the opening and closing of the air pipe.
[0025] The specific working principle is: put the device in place and connect it to the corresponding collecting device through the connecting flange, turn on the external power supply, open the box door through the handle, and during the opening process of the box door, the hydraulic support rod also rotates and stretches accordingly, and finally the hydraulic support rod can fix the opening angle of the box door, and then the staff manually injects the material into the material box. During the injection process, the dust collector extracts and absorbs the dust generated in the material box, thereby preventing it from spreading around the equipment, ensuring the air quality of the workshop and the health of the staff. At the same time, the gas storage tank can ensure the stability of the air pressure in the material box through the air pipe, and then the material in the material box flows through the material guide pipe. The conveying motor drives the driving gear to rotate, and the driving gear drives the transmission gear to rotate through the synchronous belt, and the transmission gear drives the screw to rotate, so that the screw lifts and transports the material in the conveying pipe and finally throws the material out through the discharge pipe to realize the loading of the material. In the loading process, the bearing and the gasket are designed inside the bearing seat, and the dust-proof and leakage-proof cover is sleeved on the outer side of the bearing and the gasket, so that the dust-proof and leakage-proof cover hides them to prevent dust and leakage. No matter how the machine runs, dust cannot affect the bearing, so that the device can continuously and efficiently load materials, thereby improving the use effect of the device.
