Abstract
The invention discloses a mini-tiller crawler belt traveling mechanism having a mud removal function. The mini-tiller caterpillar track traveling mechanism comprises a crawler belt and a support, a driving wheel, a guiding wheel and a tensioning wheel are arranged on the support in the form of an isosceles triangle, the mini-tiller caterpillar track traveling mechanism further comprises a mud removal device, and the mud removal device comprises a guide rod, a pull rod, a scraper plate and a tension spring. According to the mini-tiller caterpillar track traveling mechanism, the mud removal device is arranged on the support, so that the scraper plate can scrape off mud on the crawler belt, and when road holding teeth pass through the scraper plate, the tooth surfaces of the road holding teeth can push the scraper plate upward, so that the scraper plate does not interfere with movement of the crawler belt, mud removal operation is completed automatically, and thereby the technical problems that the crawler belt is stuck due to the fact that a great amount of mud adheres to the crawler belt, and the crawler belt slips due to the fact that road holding capability of the crawler belt seriously declines can be avoided; the driving wheel, the tensioning wheel and the guiding wheel are arranged on the support in the form of the isosceles triangle, so that the total length of the crawler belt is decreased, and thereby the turning radius of a crawler belt assembly can be decreased; meanwhile, a tensioning wheel adjusting mechanism and the support are simple in structure, the support is integrally of a triangular structure, and strength is good.
