Abstract
The utility model discloses an axial flow roller for a harvester, which comprises a roller shaft. A wheel is arranged on the roller shaft, a threshing pole tooth device parallel to the roller shaft is arranged on the wheel, the feeding end of the roller is a frustum body, and helical blades are arranged on the frustum body. The utility mode has simple structure, through threshing, complete separation and high efficiency, and can effectively reduce blockage, thus greatly reducing the negative impact of excessive threshed materials and separated materials on a cleaning system.
Description
Technical field
The utility model relates to the reaper thresher technical field, relates in particular to a kind of axial-flow type drum.
Background technology
Present most combine adopts axial-flow type drum to carry out threshing and separate, and axial-flow type drum adopts board-like cylinder mostly, patterns such as bar dental roller and rasp bar cylinder.After adopting above roll form, material is from entering the shelling chamber to discharge, main grass guide board by drum upper cover is realized the transporting material, this has just caused material to turn round all numbers overstand too much and in drum chamber in drum chamber, cause obstruction easily, influence the operating efficiency of cylinder, too much influence cleaning efficiency because of emersion object simultaneously.
The utility model content
It is short that technical problem to be solved in the utility model provides a kind of material time of staying in drum chamber, and it is few to turn round all numbers, avoids the too much grain header axial-flow type drum of emersion object.
For solving the problems of the technologies described above, the technical solution of the utility model is: the grain header axial-flow type drum, comprise drum shaft, and described drum shaft is provided with width of cloth dish, described width of cloth dish is provided with the threshing bar tooth device parallel with described drum shaft, and described width of cloth dish is provided with the adjusting device that is used for regulating width of cloth dish diameter.
As a kind of improvement, described threshing bar tooth device comprises the threshing bar, removes and installs the threshing bar tooth on described threshing bar.
As further improvement, described adjusting device comprises that described width of cloth plate edge is provided with groove with the corresponding position of described threshing bar is installed, and is equipped with adjustment seat on the described width of cloth dish groove.
As further improvement, the feeding end of described cylinder is a cone table, and described cone table is provided with helical blade.
After adopting such structure, because described width of cloth dish is provided with the adjusting device that is used for regulating width of cloth dish diameter, can regulate the size of width of cloth dish diameter so according to the actual needs, realize adjusting the diameter of axial-flow type drum, realize the variation of cylinder-concave clearance between axial-flow type drum and the threshing concave plate.
Again because described threshing bar tooth device comprises the threshing bar, remove and install the threshing bar tooth on described threshing bar, by such structure, can carry out dismounting to threshing bar tooth easily according to the needs of operation, regulate the strike effect of crop is enterprising at threshing performance and minimizing accommodatingly.
Again because the feeding end of described cylinder is a cone table, described cone table is provided with helical blade, can realize the quick extracting of material and with its feed roller chamber successfully, by threshing bar tooth device material is carried out threshing then and axially dredge, so material time of staying in drum chamber is short, it is few to turn round all numbers, can avoid emersion object too much.
Description of drawings
Accompanying drawing is the structural representation of the utility model embodiment.
Embodiment
As shown in drawings, the grain header axial-flow type drum, comprise drum shaft 1, evenly be installed with three width of cloth dishes 2 on the described drum shaft 1, described width of cloth dish 2 is provided with and described drum shaft 1 parallel and equally distributed threshing bar 3, also be provided with the adjusting device that is used for regulating width of cloth dish diameter on the described width of cloth dish 2, described adjusting device comprises that described width of cloth dish 2 edges are provided with groove with described threshing bar 3 corresponding positions are installed, and are equipped with adjustment seat 7 on the described width of cloth dish groove.Described adjustment seat 7 can be adjusted the diameter of axial-flow type drum by the position of bolt, nut 8, realizes the variation of cylinder-concave clearance between axial-flow type drum and the threshing concave plate.Certain described adjusting device also can be other structure, as width of cloth dish retractor device.
By bolt a plurality of threshing bar teeth 4 are installed on the described threshing bar 3, threshing bar 3 and threshing bar tooth 4 have been formed threshing bar tooth device, are used for material is carried out threshing and axially dredges.According to need of work, can pull down part threshing bar 3, by such structure, can carry out dismounting to threshing bar tooth easily according to the needs of operation, regulate the strike effect of crop is enterprising at threshing performance and minimizing accommodatingly.Certainly, also threshing bar tooth 4 can be welded on the threshing bar 3.Threshing bar tooth 4 shape is in the shape of a spiral arranged, and is even to the translocation of material, can effectively reduce cylinder and stop up.
The feeding end 5 of axial-flow type drum is the circular cone stage body, and described circular cone stage body is provided with two helical blades 6, and such structure can realize the quick extracting of material and with its feed roller chamber successfully.
The utility model is simple in structure, and through threshing separates thoroughly, and the efficient height can effectively reduce obstruction, has significantly reduced the negative effect that too much brings to cleaning and sorting system because of emersion object and separator.
