[0002] Bucket wheel stacker and reclaimer refers to a kind of high-efficiency loading and unloading machinery for continuous conveying that can both stack and retrieve materials in large dry bulk cargo yards. It consists of a belt conveyor arm that can pitch and swing horizontally and a bucket wheel at its front end, a frame, a tail car, and a running mechanism. The belt can run in both directions. When retrieving materials, the bucket wheel takes the materials and sends them out through the conveying arm. When stacking materials, the goods transported by the main conveyor are thrown into the yard through the conveying arm. The tail car is installed at the rear end of the frame. When the frame is running, it mainly moves by the wheel set at its lower end. The wheel axle of the wheel set is installed in the bearing seat of the wheel frame. In order to ensure the normal operation of the wheel set, it needs to be maintained frequently. After a long period of work, the bearing seat needs to drip lubricating oil into the rolling body inside it to reduce the friction between the rolling body and the inner and outer rings, thereby increasing the service life of the entire wheel set. However, at this stage, when adding lubricating oil, the staff manually drips the lubricating oil into the bearing seat. This process is time-consuming and labor-intensive, which brings great inconvenience to the maintenance of the wheel set. Utility Model Content

[0025] An oil tank 8 is provided on the top of the vehicle plate 1 at a position corresponding to the wheel frame 4, and oil outlets are provided on the bottom of the oil tank 8 at positions corresponding to the bearing seats 5 on both sides. A vertical first through hole 1a is provided on the vehicle plate 1 at a position corresponding to the bearing seat 5, and a vertical second through hole 4a is provided on the side wall of the wheel frame 4. The lower end of the second through hole 4a is opened to the upper end of the outer ring 5a, and a third through hole 5d is provided on the top of the outer ring 5a. The lower end of the third through hole 5d passes through the rolling body 5c. The first through hole 1a, the second through hole 4a and the third through hole 5d are interconnected to form an oil filling channel, and an oil pipe 9 inserted into the first through hole 1a is provided at the oil outlet of the oil tank 8.

[0026] An oil pump 10 is arranged in the oil tank 8 at a position corresponding to the oil outlet, and the oil pipe 9 is connected to the oil pump 10 .

[0027] A bracket 11 is provided on the top of the vehicle plate 1 at a position above the corresponding transport wheel set, and the oil tank 8 is installed on the top of the bracket 11 .

[0028] A cleaning assembly is provided at the bottom of the vehicle plate 1 at a position corresponding to one side of the wheel 7 .

[0029] The cleaning assembly comprises a mounting frame 12 arranged at the bottom of the vehicle plate 1 , and a scraper 13 is arranged on the mounting frame 12 at a side close to the wheel 7 .

[0030] The scraper 13 includes a vertical rod 13 a detachably connected to the mounting frame 12 , and a scraper 13 b extending toward one side of the wheel 7 is provided at the lower end of the vertical rod 13 a , and the end of the scraper 13 b is attached to the outer side of the wheel 7 .

When the transport wheel set at the bottom of the vehicle plate needs to be oiled and maintained, the oil pump 10 in the oil tank 8 can be started. The oil pump 10 pumps out the lubricating liquid in the oil tank 8 and flows out through the oil pipe 9. At this time, the pumped lubricating liquid enters the first through hole 1a on the vehicle plate through the oil pipe 9, then flows through the second through hole 4a and the third through hole 5d and finally flows into the mounting cavity of the rolling body 5c. When the wheel 7 rotates, the rolling body 5 will rotate, so that the injected lubricating liquid is evenly filled in the cavity of the rolling body 5c, so that all the rolling bodies 5c can be coated with the lubricating liquid. The lubricating liquid is added in this way, which saves manual operation, so that the tail car can be oiled and maintained during operation. When the tail car is driving, the scraper 13b will scrape the surface of the wheel 7, so as to scrape off the impurities adhering to the surface of the wheel 7, thereby ensuring the cleanliness of the surface of the wheel 7, thereby ensuring the smooth operation of the tail car.
