Embodiment Construction

[0009] In Fig. 1, the first stage is a chain transmission, the driving sprocket is mounted on the output shaft of the intermediate transmission box 1, the passive sprocket is mounted on the transition transmission shaft 8, and the driving sprocket and the passive sprocket are driven through the chain 7; The second stage is a belt transmission, and its driving pulley is contained on the transition transmission shaft 8, and the passive pulley is the header power input wheel 4, which is installed on the header input drive shaft, and two belt pulleys pass through belt 10 transmissions. One side of the belt 10 is provided with an automatic tension separation mechanism, which is mainly composed of tension pulley 5, tension support 6, tension spring 9 and separation flexible shaft 3. One end of the separation flexible shaft 3 is connected to the header transmission box 12, and the other end is connected to the rear end of the tension bracket 6. One end of the tension spring 9 is conne...

Abstract

The invention discloses a transmission arrangement for half-feed-in type rice and wheat combine-harvester cutting platform which includes two-stages of speed reducing, the first stage being a chain drive, which is driven by intermediate gearing box and transitional drive shaft arranged on the housing through chains, the second stage being a belt drive which is driven by the transitional drive shaft and cutting platform power feed-in wheel through a belt. The invention can be applied to guarantee the stabilization cutting and transporting velocity for the harvesters.

Description

technical field [0001] The invention relates to a transmission device for a header of a semi-feeding rice and wheat combine harvester. Background technique [0002] At present, the transmission device of the semi-feeding rice and wheat combine harvester header is composed of an outreach shaft of a travel gearbox driven by a hydraulic stepless transmission, and a one-way clutch mounted on the overhang shaft. When the machine is in the harvesting state, when it is moving forward, the power comes from the engine, which is transmitted to the header through the hydraulic continuously variable transmission, travel gearbox and one-way clutch to make the header run; when the machine is backward, no power is transmitted due to the reverse rotation of the one-way clutch , the header does not operate to meet the harvesting performance requirements of the half-feed rice-wheat combine harvester. However, there are following defects in this one-way clutch transmission structure: (1) when...
