Description

Technical Field

[0001] The utility model belongs to the technical field of coal feeders, and in particular relates to an automatic travel adjustment mechanism for a ring-type coal feeder. Background Art

[0002] Ring-type coal feeders are used to unload coal from circular silos. They are widely used at the bottom outlet of silos in industries such as power, chemical, and coal. Due to the circular structure of silos, the unloading equipment's main structure is ring-shaped. Its overall dimensions vary depending on the silo's diameter, with current equipment typically accommodating maximum diameters ranging from 22 meters to 50 meters. The coal feeder primarily consists of a plow car and a coal unloading car body, a wheel assembly, a pinion gear drive, a drive unit, a plowshare, a discharge mechanism, and an electronic control system. The feeder unloads coal by rotating in a circular motion around the silo's lower cone, centered at the center of the silo. The plowshares on the upper plow car scrape coal from the silo onto the coal receiving tray on the lower unloading car body. The discharge mechanism then unloads the coal into a discharge hopper for transport on a belt conveyor. The entire system is supported by several steel wheels mounted on the plow car body and the unloading car floor. The steel wheels are evenly spaced around the center of the car body. The coal feeder is rail-type and its running track is circular. The drive unit realizes pin-tooth transmission by engaging the pinion gear with the pinion gear on the car body frame, which in turn drives the several running wheels at the bottom of the car body to rotate along the circular track installed on the foundation to perform circular motion.

[0003] The prior art discloses a Chinese utility model patent application numbered 202221309547.6, which discloses a coal unloading car for a ring-type coal feeder. The patent comprises a car body, a ring track, a pin plate, and a drive device. The car body is rotatably mounted on the ring track via wheels at its bottom. The pin plate comprises a pin holder and a pin. The pin holder is fixedly mounted on the outer edge of the car body, and the pin is fixedly mounted on the pin holder in a radial direction of the car body. The drive device comprises at least three groups distributed along the circumference of the car body. The drive device comprises a base, a gear, and a gear drive motor. The gear is mounted on the base in a radial direction of the car body. The gear drive motor is mounted on the base and connected to the gear, and the gear meshes with the pin. The present utility model avoids the difficulty of cleaning in the prior art due to the protrusion of the pin's upper end from the pin holder by arranging the pin horizontally. Furthermore, a gear adapted to the horizontal pin is provided to ensure normal operation of the equipment.

[0004] The above-mentioned existing technologies still have shortcomings: due to the errors in the horizontal and vertical directions of the track surface during the installation of the circular track foundation, the track surface is uneven or wavy; the bottom surface of the plow coal car and the coal unloading car body in the equipment is also uneven during the entire assembly, and there are many factors such as the size and manufacturing errors of the wheel group. As a result, when the coal feeder is running, the wheels cannot fully contact the track surface, causing uneven load-bearing on the car body, equipment vibration, and affecting the service life of the equipment, or the car body is skewed, causing the entire equipment to shift during operation, resulting in unreasonable engagement during pin gear transmission, loud noise during operation, or even malfunction of the equipment. Therefore, it is necessary to provide an automatic adjustment mechanism for the travel of a ring-type coal feeder to solve the above-mentioned technical problems. Utility Model Content
