Description
Technical Field
The utility model belongs to the field of agricultural automation, and particularly relates to a wheel-foot combined orchard conveyor.
Background
The orchard transporter is used as a main machine for transporting orchard crops and mainly comprises a wheel transporter, a crawler-type transporter and a rail-type transporter. Wheel-type conveyors and crawler-type conveyors are widely applied, however, orchards in mountainous regions and hills in China account for most of all orchards in China, and in these regions, the terrains are complex and rugged, gullies are vertical and horizontal, branches are staggered and vertical and horizontal, no rules exist, so that the problems not only make the traditional orchard conveyor with the chassis height incapable of being adjusted extremely difficult to work in the region, but also greatly improve the labor intensity of farmers.
In the north of China, fruit growers mainly use wheel type and crawler belt transportation machines to transport fruits; in the south of China, the crawler conveyor is also widely applied. The spacing between fruit trees in many orchards in China is narrow, the branches are criss-cross, and the terrain of some orchards is complex, so that wheel type and crawler type transport machinery cannot smoothly enter the orchards. Meanwhile, some wheeled conveyers and crawler conveyers have higher or lower chassis and are not easy to flexibly shuttle in old densely planted orchards. For example, in the chinese patent application (application No. 201910646749.6) "a hillside orchard conveyor and a self-balancing objective table thereof", although the problem of leveling of the crawler conveyor during the transportation process is solved by adjusting the extension length of the balancing electric cylinder, the crawler conveyor still has the problems of a lower chassis and difficulty in adjusting the height of the chassis, and is not easy to realize a larger obstacle crossing function. For example, the chinese utility model patent application (application No. 201621451998.8) "a running gear applied to hillside orchard conveyor" is a rail conveyor, which can adapt to hillside terrain well, but is affected by natural disasters and market prices, and fruit growers are reluctant to purchase a rail conveyor with high cost. In addition, the rail transport machine has a problem of insufficient reliability.
