Problems solved by technology

However, this device is not suitable for crops with a large ear width difference, and its supporting clamping and conveying device has a complex structure and high cost
Commonly used axial flow threshing devices have three types of concave plates: grid screen type, punching screen type, and woven screen type. Among them, the grid screen type concave plate has the strongest threshing and separation ability, but the stems are seriously broken.
In addition, the above-mentioned threshing and separating devices generally cannot adapt to the threshing requirements of various crops through simple adjustments.

Embodiment Construction

[0019] Figure 1 is the left view of the assembly of the axial flow threshing separation device, including the threshing cylinder and the concave plate. Plate teeth 4 are installed to form a composite threshing element, and the short grain bar-plate tooth composite threshing element is arranged in a spiral on the threshing drum as shown in Figure 10. The threshing and separation of crops is achieved by the combined action of the rubbing of the short grain rod 2 and the striking of the plate teeth 4. During the threshing process, there are both rubbing and impact, high cleaning rate, small entrainment loss, less grain damage, and low handle rate. , the stalk is lightly broken, and the impurity content in the prolapse is low; the length of the short-grained rod 2 is 50-150mm, and the height of the plate teeth 4 is 60-100mm; the separation concave plate adopts a grid-punching combination form, and the front section is a grid Sieve type 10, enhance the threshing and separation abil...

Abstract

The present invention relates to a tangential feeding axial-flow threshing separation equipment. Its threshing element adopts short threaded rod-toothed bar combination structure, said short threaded rod is mounted on the threaded rod seat, the toothed bar is positioned at one side of threaded rod seat, its recessed plate adopts grid sieve and punching sieve combination structure, the above-mentioned two structures can be matched with threshing drum so as to implement threshing and separation of crops. Said invention can be used for threshing and separation of several crops of rice, wheat, rape and soybean, etc.

Description

technical field [0001] The invention relates to a tangential feeding axial flow threshing and separation device for a harvesting machine, which is mainly used for detaching grains of various crops such as rice, wheat, rape and soybean from ears. Background technique [0002] At present, the harvesting mechanical threshing and separating devices mainly include a bar-shaped drum-type threshing device, a spike-toothed drum-type threshing device, and a bow-toothed drum-type threshing device. The grained rod drum type threshing device generally adopts an integral grid concave plate, which is mostly used in a cross-flow type threshing device. It mainly relies on kneading for threshing. The threshing flexibility is large, the stalks are lightly broken, and the removal rate is relatively low when removing difficult crops. , large entrainment loss, sensitive to wet crops, and poor adaptability. Spike-tooth threshing drum type threshing devices generally also use integral grid concav...
