Embodiment Construction

[0009] in figure 1 Among them, the first stage is chain transmission, the active sprocket is installed on the output shaft of the intermediate transmission box 1, the passive sprocket is installed on the transition drive shaft 8, the active sprocket and the passive sprocket are driven by the chain 7; the second stage It is a belt drive. The driving pulley is installed on the transition drive shaft 8, and the passive pulley is the power input wheel 4 of the header, which is installed on the input transmission shaft of the header. The two pulleys are driven by the belt 10. An automatic tensioning and separating mechanism is provided on one side of the belt 10, and the automatic tensioning and separating mechanism is mainly composed of a tensioning wheel 5, a tensioning bracket 6, a tensioning spring 9 and a separating flexible shaft 3. One end of the separating flexible shaft 3 is connected to the header transmission box 12, the other end is connected to the rear end of the tension ...

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 cutting table of a half-feeding rice and wheat combine harvester. Background technique [0002] At present, the transmission device of the header of a half-feeding rice-wheat combine harvester is composed of an outreach shaft of a traveling gearbox driven by a hydraulic continuously variable transmission, and a one-way clutch mounted on the outreach shaft. When the machine is in the harvesting state, the power comes from the engine, through the hydraulic stepless transmission, the traveling gearbox and the one-way clutch, and is transmitted to the header to make the header run; when the machine is moving backward, the one-way clutch does not transmit power due to the reverse rotation , The header does not operate to meet the harvesting performance requirements of the half-feed rice-wheat combine harvester. However, this one-way clutch transmission structure has the following defects: (1) When harvesting c...
