Problems solved by technology
Among them, the threshing gap of the threshing device is an important factor affecting the working quality of the combine harvester. In the actual harvesting process, the operating conditions of the combine harvester will change in real time. If the operating parameters of the threshing device are not adjusted with the change of operating conditions, it will seriously affect the combine Harvester performance
Most of the existing ways to change the threshing gap are to adjust the distance between the concave plate screen and the threshing drum, and then change the entire threshing gap. The second is that only changing the threshing gap can not change the linear speed of the threshing element, which does not greatly improve the threshing adaptability of the combine harvester.

Embodiment Construction
[0034] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but the protection scope of the present invention is not limited thereto.
[0035] Such as figure 1 As shown, the diameter-adjustable threshing drum of the present invention includes a threshing drum, a diameter adjusting device, a driving device, and a locking device. The second support disc 102 and the first support disc 101, the driving device and the locking device are located at the tail of the threshing drum, and are installed outside the first support disc 101 of the threshing drum.
[0036] The threshing drum includes a drum shaft 107, a screw feed wheel 109, a support disc four 104, a support disc three 103, a support disc two 102, a support disc 103, a support disc two 102, and a support wheel 109 mounted on the drum shaft 107 from front to back along the material transfer direction. The first disc 101, the threshing gear bar 105 insta...

The invention provides a threshing drum with an adjustable threshing diameter and a combine harvester. The threshing drum comprise a threshing drum body, diameter adjusting devices, a driving device and a locking device, wherein the diameter adjusting devices are arranged at inner sides of a front support disc and a rear support disc of the threshing drum. Electric and manual modes are adopted fordriving and locking, the driving device is used for transmitting power to the diameter adjusting devices, and the threshing diameter of the drum can be adjusted steplessly through the diameter adjusting devices; and meanwhile, the locking device can be used for effectively locking the adjusted diameter of the drum so as to ensure the operation stability of the drum. The threshing diameter of thedrum of the combine harvester can be adjusted conveniently and rapidly, so that the threshing linear speed and threshing gap of the threshing drum are adjusted according to the situation of harvest atany time, and the threshing adaptability of the combine harvester is improved.
Description
technical field [0001] The invention relates to the technical field of harvesting machinery, in particular to a combine harvester for harvesting cereal crops, especially a threshing device with adjustable threshing diameter. Background technique [0002] The threshing device is the core component of the combine harvester threshing device, which plays the role of threshing the plants. Among them, the threshing gap of the threshing device is an important factor affecting the working quality of the combine harvester. In the actual harvesting process, the operating conditions of the combine harvester will change in real time. If the operating parameters of the threshing device are not adjusted with the change of operating conditions, it will seriously affect the combine Harvester performance. Most of the existing ways to change the threshing gap are to adjust the distance between the concave plate screen and the threshing drum, and then change the entire threshing gap. The sec...
