Abstract
The utility model relates to a thresher, in particular to a drum of a thresher. The drum comprises a plurality of rods, circular end plates and a transmission shaft, positioning washers are arranged on the transmission shaft and provided with via holes, the circular end plate and the transmission shaft are connected via bolts, a row of teeth extending outwards is arranged on each rod, the rods are connected to outer edges of the two end plates to form a drum cage, the transmission shaft is arranged at the center of the drum cage, the teeth include lateral bending teeth for guiding straws and reverse lateral bending teeth for preventing straws twining, wherein the lateral bending teeth are bent to a straw outlet and arranged at positions corresponding to the straw outlet and along the rods, the reverse lateral bending teeth are arranged at one end of each rod corresponding to the straw outlet, and the rods are tubular structures and fixed on the end plates via bolts. The combined drum of the thresher, which adopts the technical scheme, has the advantages that components of the drum can be replaced conveniently, straws can be discharged smoothly, and straw twining can be avoided.
Description
Technical field
The utility model relates to a kind of thresher, is specifically related to a kind of cylinder of thresher.
Background technology
Thresher generally is made up of frame, charging aperture, threshing cylinder, concave grate, grass outlet cover, cleaning fan and mote separating mechanism etc.; material at first carries out threshing by cylinder and concave grate relative motion after entering in the machine; the straw of deviating from is discharged by the outlet grass; the seed that falls, standing grain bits, standing grain fringe head are cleaned by mote separating mechanism, blower fan again, to reach straw, standing grain bits, the disposable separation of seed three.The threshing cylinder that existing thresher is used mostly is the finger rod-type, exists more problem in the use: 1, refer to that bar is tiny, and damage easily, because the finger bar on the cylinder all is directly to be welded on the end plate, refer to the maintain and replace inconvenience of bar, the replacement cost height; 2, grass outlet adopts offset usually, therefore needs material end motion to cylinder in cylinder; therefore refer to that the finger on the bar mostly is unidirectional lateral bending; the immediate problem that this kind situation causes is that straw very easily is wound on the axle of thresher, cause grass not smooth, even thresher is stuck flame-out.
The utility model content
The technical problems to be solved in the utility model is: provide a kind of drum part to change conveniently, go out grass thresher combined type cylinder smoothly.
In order to solve the problems of the technologies described above, the utility model is carried a kind of thresher combined type cylinder, include the finger bar, circular end plate and power transmission shaft, power transmission shaft is provided with locating pad, via hole is arranged on the locating pad, adopt bolt to be connected between circular end plate and the power transmission shaft, refer to that bar is provided with an exclusive finger tooth of stretching, several refer to that bar is connected the outer rim formation cylinder cage of two end plates, power transmission shaft be arranged on the cylinder cage in the heart, described finger tooth refers to tooth by the lateral bending of leading grass and prevents twining careless reverse side dactylogryposis tooth and form, wherein, lateral bending refers to that tooth bends towards the grass outlet direction, and it is along referring to that bar is aligned to the position of grass outlet correspondence, and reverse side dactylogryposis tooth is arranged on finger bar one end of grass outlet correspondence; The finger bar is a tubular structure, and it is by being bolted on the end plate.
Adopt the following advantage that has of technique scheme: 1, owing to refer to that bar is provided with the lateral bending of leading grass and refers to tooth and the anti-reverse side dactylogryposis tooth that twines grass, it is reached when grass led grass outlet, push away, can effectively avoid straw to be wound on the axle of thresher by the counter of reverse lateral bending tooth; 2, refer to that bar is a tubular structure, it can be when the finger tooth and hair on referring to bar be given birth to damage by being bolted on the end plate, and directly replacing refers to bar, and need not change whole cylinder, has reduced maintenance cost.
As preferred version, for the ease of fixing and dismounting cylinder, described power transmission shaft two ends are provided with bearing block, can directly bearing block be fixed to above the support.

Fig. 2 is the structural representation of another angle of the utility model embodiment one.
Embodiment
Below in conjunction with drawings and Examples technical solutions of the utility model are further specified:
Embodiment one
As depicted in figs. 1 and 2; the utility model provides a kind of thresher combined type cylinder; include the finger bar 1 of tubulose; circular end plate 2 and power transmission shaft 3; bearing block 4; refer to that bar 1 is provided with an exclusive finger tooth of stretching; refer to that tooth is referred to tooth 51 and prevented that twining careless reverse side dactylogryposis tooth 52 forms by the lateral bending of leading grass; lateral bending refers to that tooth 51 bends towards the grass outlet direction; and along referring to bar 1 evenly distributed position to the grass outlet correspondence; reverse side dactylogryposis tooth 52 is arranged on finger bar 1 one ends of grass outlet correspondence; refer to that bar 1 is a tubular structure; five finger bars 1 are bolted to connection the outer rim formation cylinder cage of two end plates 2; the central shaft that power transmission shaft 3 is arranged on the cylinder cage makes progress; it is provided with locating pad, and via hole is arranged on the locating pad, by the center of bolt to two end plate 2; bearing block 4 is arranged on power transmission shaft 3 two ends, and bearing block 4 can directly be fixed on the frame by bolt.
Above-described only is preferred implementation of the present utility model; should be understood that; for a person skilled in the art; under the prerequisite that does not break away from the utility model structure; can also make some distortion and improvement; these also should be considered as protection domain of the present utility model, and these can not influence effect and practical applicability that the utility model is implemented.
Claims (2)
1. thresher combined type cylinder, include the finger bar, circular end plate and power transmission shaft, power transmission shaft is provided with locating pad, via hole is arranged on the locating pad, be connected by bolt between circular end plate and the power transmission shaft, refer to that bar is provided with an exclusive finger tooth of stretching, several refer to that bar is connected the outer rim formation cylinder cage of two end plates, power transmission shaft be arranged on the cylinder cage in the heart, be characterised in that: described finger tooth refers to tooth by the lateral bending of leading grass and prevents twining careless reverse side dactylogryposis tooth and form that wherein, lateral bending refers to that tooth bends towards the grass outlet direction, it is along referring to that bar is aligned to the position of grass outlet correspondence, and reverse side dactylogryposis tooth is arranged on finger bar one end of grass outlet correspondence; The finger bar is a tubular structure, and it is by being bolted on the end plate.
