Problems solved by technology

[0002] At present, the nail teeth and the guide plate of the upper cover of the axial flow drum threshing device are usually fixed. The design of this axial flow drum threshing device is usually carried out for one crop, and farmers usually plant two to three crops throughout the year. If the threshing of these crops uses an axial flow drum threshing device, it will inevitably cause unclean threshing of certain crops, and increase the loss rate and damage rate of another crop.

Embodiment Construction

[0020] As shown in Figure 1, the adjustable axial flow drum threshing device of the present invention includes: a rotating shaft 1, spikes, spiral pieces 16, feeding trough 12, baffle plate 17, and upper cover 14. The spiral pieces 16 are mounted on the rotating shaft 1. At the front end, the nail teeth are fixed in the axial center of the rotating shaft 1, and the nail teeth are evenly distributed along the axial and radial directions of the rotating shaft 1. The nail teeth include a fixed nail tooth 8 and a movable nail tooth 9. The frame 10 is fixed on the rotating shaft 1. One end of the movable spike 9 extends from the fixed sleeve 7 fixed on the fixed frame 10, and the other end is connected to the wedge 6 on the tie rod 3 that slides along the axis of the rotating shaft 1. For inclined surface contact, the movable spike 9 is equipped with a spring 5, one end of the spring 5 is in contact with the fixed sleeve 7, and the other end is in contact with the inclined surface of t...

Abstract

The invention relates to adjustable axial-flow cylinder threshing device which comprise rotating axle, spike tooth, spiral blade, feeding groove, baffle and upper cover. The spiral blade is mounted at front of rotating axle, spike tooth is fixed at axial center of rotating axle and distribute evenly along axial and longitudinal of the axle. The spike tooth comprise fixed spike tooth and movable spike tooth. The fixed spike tooth is fixed to rotating axle by fixing rack. One end of movable spike tooth extends out from fixing envelope fixed on fixing rack, the other end contact with inclined surface of wedge block on the pull rod sliding axially along rotating axle. The device can thresh the corn, rice, buckwheat, soybean etc. Adjusting movable spike tooth height can effectively control threshing intensity, adjusting included angle between movable guiding plate and upper cover axial line can effectively control threshing time. The present device largely reduce the damage rate of crops in addition to the clean threshing.

Description

Technical field [0001] The invention relates to a drum threshing device, in particular to an adjustable axial flow drum threshing device. Background technique [0002] At present, the nail teeth of the axial flow drum threshing device and the guide plate of the upper cover are usually fixed. The design of this axial flow drum threshing device is usually carried out for one crop, and farmers usually plant two to three crops throughout the year. For crops, if the threshing of these crops uses an axial flow drum threshing device, it will inevitably cause the threshing of certain crops to be unclean, and the loss rate and damage rate of another crop will increase. Summary of the invention [0003] In view of the above reasons, the purpose of the present invention is to overcome the above defects and provide an adjustable axial drum threshing device whose nail teeth can be adjusted up and down along the radial direction of the rotating shaft, and the movable guide plate of its upper ...
