Telescopic shifting finger protecting cover structure for spiral pushing and conveying device and mounting mode

Abstract

The invention provides a telescopic shifting finger protecting cover structure for a spiral pushing and conveying device and a mounting mode. The telescopic shifting finger and protecting finger cover structure is that a telescopic shifting finger can be telescoped and fed on a conveying roller of a cutting platform of a harvesting machine through a complete single-degree-of-degree connecting mechanism; a telescopic shifting finger cover is formed by combining an inner cover and an outer cover and is fixedly mounted on the roller; a rotating block is arranged in the telescopic shifting finger cover and oscillated by a reciprocating manner, wherein the rotating block sleeves a shifting finger rod; the shifting finger rod can telescopically slide in the rotating block; the telescopic shifting finger cover, the telescopic shifting finger and the rotating block are mounted in the roller of the cutting platform of the harvesting machine.

Description

technical field [0001] The invention relates to a structure and installation method of a telescopic finger protector for an auger, in particular to a novel telescopic finger movement mechanism and an installation structure of a header drum of an agricultural full-feed combine harvester. It belongs to the technical field of agricultural machinery manufacturing. Background technique [0002] The operation process of a typical full-feed rice and wheat harvesting machine is: cutting, conveying, threshing, cleaning, and siloing. The auger is a material conveying device widely used in rice and wheat harvesting machinery. Its main function is to transport the ears of rice and wheat cut off by the harvesting mechanical header to the threshing and cleaning device, and the transport process must be smooth and not blocked. The conveying work of the auger is divided into two aspects. On the one hand, when the drum rotates, the continuous left-handed or right-handed helical blades arra...

Problems solved by technology

Among them, the structure of the finger guard is as follows: figure 2 As shown, in addition to linear sliding, that is, telescopic movement, the dial finger relative to the finger guard will also produce a relatively large lateral swing. In the process of swinging back and forth, due to the rapid reversal, the lateral movement of the dial finger will have a large impact. Instantaneous acceleration will inevitably cause a strong impact between the finger and the sheath, causing vibration, continuous collision and friction between the finger and the sheath, resulting in unnecessary energy loss
