Abstract
The utility model provides a threshing device of a harvester. The threshing device of the harvester comprises a threshing cylinder and a concave plate sieve, wherein the threshing cylinder comprises threshing toothed bars, a rotary shaft and a roller radial disc, the threshing toothed bars are evenly arranged on the threshing cylinder in the circumferential direction, threshing teeth with two different lengths are arranged on the threshing toothed bars, the threshing teeth are evenly arranged on each threshing toothed bar from the feed inlet of the threshing cylinder in sequence in a mode that the lengths of the threshing teeth become larger gradually, the working clearance between each shorter threshing tooth and the concave plate sieve is 20mm, the working clearance between each longer threshing tooth and the concave plate sieve is 15mm, a plurality of installation holes used for installation of the threshing toothed bars are formed in the roller radial disc, and the positions, relative to the roller radial disc, of the threshing toothed bars are adjustable in the radial direction. The threshing device of the harvester has the advantages that the load weight of the threshing device can be effectively reduced during work, and energy consumption is reduced; meanwhile, due to the fact that the diameter of the threshing cylinder can be adjusted according to the variety of grain, targeted adjustment is achieved, unnecessary harvesting loss is avoided, and the threshing performance is improved.
Description
Technical field
The utility model belongs to field of agricultural machinery, relates to a kind of grain header, particularly a kind of reaper thresher.
Background technology
Existing rice/wheat combine sheller unit adopts same diameter threshing cylinder, and namely the gap of threshing cylinder and concave grate is constant to the straw outlet size from feeding mouth, adopts this kind threshing cylinder to carry out threshing and separates, and has following shortcoming:
The one, load is heavy during sheller unit work, and power consumption is large;
The 2nd, varietal adaptation is poor, can not realize the specific aim adjustment to the crop of different cultivars.Can't effectively clean threshing to some crop, cause yield loss large.
The utility model content
The utility model provides a kind of reaper thresher, and purpose is that load is heavy when reducing sheller unit work, reduces power consumption.
To achieve these goals, the technical scheme taked of the utility model is:
Described reaper thresher, comprise threshing cylinder and concave grate, described threshing cylinder comprises threshing toothed bar, rotating shaft and cylinder spoke dish, described threshing toothed bar circumferentially evenly arranges on described threshing cylinder in the mode that is parallel to rotating shaft, described threshing toothed bar radial outward evenly is provided with threshing tooth along its length, described threshing tooth has two kinds of different length at least, and described threshing tooth is successively set on the described threshing toothed bar from the porch of described threshing cylinder from short to long.
Described threshing toothed bar is removably mounted on the described cylinder spoke dish, and described cylinder spoke disc radial is provided with a plurality of installing holes be used to described threshing toothed bar is installed.
Short threshing tooth and the working clearance between the described concave grate of length is 20mm, and the working clearance between another kind of threshing tooth and the described concave grate is 15mm.
Adopt technique scheme, load is heavy when effectively reducing sheller unit work, reduces power consumption.Can change according to kind simultaneously the diameter of threshing cylinder, realize the specific aim adjustment, avoid unnecessary yield loss, improve the threshing performance of threshing.
Description of drawings
Fig. 1 is the structural representation of the utility model reaper thresher;
Fig. 2 is the left view of structure shown in Figure 1.
Being labeled as among Fig. 1 to Fig. 2:
1, rotating shaft; 2, threshing toothed bar; 3, cylinder spoke dish; 4, concave grate.
Embodiment
The below contrasts accompanying drawing, by the description to embodiment, embodiment of the present utility model is described in further detail, and to help those skilled in the art inventive concept of the present utility model, technical scheme is had more complete, accurate and deep understanding.
To shown in Figure 2, the utility model provides a kind of reaper thresher, comprises threshing cylinder and concave grate 4 such as Fig. 1.Threshing cylinder comprises threshing toothed bar 2, rotating shaft 1 and cylinder spoke dish 3.Described threshing toothed bar 2 circumferentially evenly arranges on threshing cylinder, installs by cylinder spoke dish 3, and parallel with rotating shaft 1.
Threshing toothed bar 2 circumferentially evenly arranges on described threshing cylinder in the mode that is parallel to rotating shaft 1, and threshing toothed bar 2 radial outward evenly are provided with two kinds of threshing tooths that are uneven in length along its length.From threshing cylinder feeding mouth one end, threshing tooth is successively set on the threshing toothed bar 2 from short to long.Short a kind of threshing tooth and the working clearance of concave grate 4 are 20mm, and the working clearance of another kind of threshing tooth and concave grate 4 is 15mm.
Threshing toothed bar 2 is removably mounted on the described cylinder spoke dish 3 by the ratch holder, and a plurality of installing holes for threshing toothed bar 2 is installed are arranged on the cylinder spoke dish 3.The position of the relatively described cylinder spoke of threshing toothed bar 2 dish 3 is radially adjustable, can change according to the kind for the treatment of the threshing crop diameter of threshing cylinder.So just can avoid unnecessary yield loss, improve the threshing performance of threshing.
When this sheller unit work, treat that the threshing product is entered by the entrance of threshing cylinder, be subjected to first threshing tooth effect short on the threshing toothed bar 2, the threshing tooth effect of being grown again.Like this porch threshing cylinder bear duty ratio tradition threshing cylinder little.Through the threshing of short threshing tooth, long threshing tooth can not bear too large load yet when threshing, has reduced the consumption of power.
The above has carried out exemplary description to the utility model by reference to the accompanying drawings; obviously the concrete realization of the utility model is not subjected to the restriction of aforesaid way; as long as the various improvement of having adopted method design of the present utility model and technical scheme to carry out; or directly apply to other occasions without improvement, all in protection domain of the present utility model.
