Description
Technical field
This utility model belongs to field of agricultural machinery, in particular it relates to a kind of harvester drum threshing tooth device.
Background technology
Paces recently as Tendency of Agricultural Machinery in China are constantly accelerated, and the yield of crops also increases substantially, and peasant is more and more higher to the requirement of the Mechanical harvesters of results crops.Harvester threshing mainly by extruding between threshing tooth and screen cloth, crumple, rub, grain is taken off from the fringe portion of crops.Existing threshing tooth is generally two kinds of shapes: a kind of is the V-shaped structure that isosceles are symmetrical, easily wearing and tearing in the front side of this kind of threshing tooth, service life is shorter, and threshing tooth root is bolt arrangement, bolt is connected with threshing cylinder, and this connected mode is inconvenient when changing or install threshing tooth；Another kind is approximate right angle triangle, although this structure extends the service life of threshing tooth, but still suffers from threshing tooth and be difficult to cut the problem in numerous crop fringe bottom portion, grain is caused to be difficult to take off, and its approximate right angle triangular structure makes force position protract, easily cause screen cloth and damage.
Utility model content
The purpose of this utility model is to provide a kind of simple in construction, and service life is long, easy for installation firmly, improve the harvester threshing tooth of harvester threshing efficiency.
For solving above-mentioned technical problem, the technical solution adopted in the utility model is:
Thering is provided a kind of drum threshing tooth device, including ratch and be arranged on threshing tooth on ratch, described ratch offers some installing holes, described installing hole is axially uniformly distributed along described ratch, and described installing hole diameter is less than described ratch radial diameter；Described threshing tooth is connected with described ratch by a threshing tooth mounting seat, the cross section of described threshing tooth mounting seat is curved, described threshing tooth mounting seat matches with described ratch periphery, and described threshing tooth is cylinder, and described threshing tooth cross-sectional diameter is less than or equal to described installing hole diameter.
Preferably, for the ease of the installation of threshing tooth, described threshing tooth penetrates described threshing tooth mounting seat and inserts in described installing hole.
Preferably, described threshing tooth mounting seat and threshing tooth, threshing tooth mounting seat are with ratch and are welded to connect.
Compared with prior art, the beneficial effects of the utility model are:
This utility model is by using the threshing tooth with threshing tooth mounting seat, threshing tooth can be realized be inserted directly in ratch and position, then by the way of welding, realize the connection of threshing tooth mounting seat and ratch, this utility model is simple and reasonable, manufacture easily, low cost, service life is long.
Accompanying drawing explanation
Fig. 1 is the structure chart of this utility model a kind of drum threshing tooth device；
Fig. 2 is threshing tooth and the structure chart of threshing tooth mounting seat in this utility model.
In figure, 1, ratch, 2, threshing tooth, 3, installing hole, 4, threshing tooth mounting seat.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, this utility model is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain this utility model, is not used to limit this utility model.
Refering to shown in Fig. 1 and Fig. 2, a kind of drum threshing tooth device is provided, including ratch 1 and be arranged on threshing tooth 2 on ratch 1, described ratch 1 offers some installing holes 3, described installing hole 3 is axially uniformly distributed along described ratch 1, and described installing hole 3 diameter is less than described ratch 1 radial diameter；Described threshing tooth 2 is connected with described ratch 1 by a threshing tooth mounting seat 4, the cross section of described threshing tooth mounting seat 4 is curved, described threshing tooth mounting seat 4 matches with described ratch 1 periphery, described threshing tooth 2 is cylinder, and horizontal 2 diameter of sections of described threshing tooth are less than or equal to described installing hole 3 diameter.
Preferably, for the ease of the installation of threshing tooth 2, described threshing tooth 2 penetrates described threshing tooth mounting seat 4 and inserts in described installing hole 3.
Preferably, described threshing tooth mounting seat 4 and threshing tooth 2, threshing tooth mounting seat 4 are with ratch 1 and are welded to connect.
The above embodiments are only preferred embodiment of the present utility model, it is impossible to limit interest field of the present utility model, therefore, the equivalent variations made according to this utility model claim with this, still belong to the scope that this utility model is contained.
