Abstract
The utility model relates to a drum of a corn thresher. The structure of the traditional drum of a corn thresher is that fingers are arranged on the circular drum in a helix way; a gap between a concave and the drum of the structure is not changed in the working process; corn grains are shed from the ears of corns primarily by the striking action of the rotating fingers, and the kneading action to the ears of corns is poor; in this manner, the power is wasted, and the size of the over-crushed corncob is close to the size of the corn grains, which brings difficulty to the separating and cleanness of the corn grains; the excessive striking action can also damage the corn grains and decrease the grade of the corn grains. The novel drum of a corn thresher comprises a drum 6 and end plates 4 installed on both sides of the drum, wherein the section of the drum is a polygon, and the end plates 4 are vertically fixed on a drum shaft 5; the end plates 4, a finger base 2 and a sealing plate 3 form a sealing drum casing, and fingers 1 are arranged on the finger base 2. The machine is used in the corn thresher in the field of agricultural machinery.
Description
Technical field: the utility model relates to the novel corn thresher cylinder that uses on the husker sheller in a kind of agricultural machinery.
Background technology: traditional husker sheller roller frame all is the spike-tooth that is being arranged by spiral on circular drum, and the cylinder of this structure is constant in the gap of its course of work intermediate roll and notch board.Corn kernel mainly leans on the strike effect of rotating spike-tooth and splits away off from corncob, and is relatively poor to the kneading action of corncob.So not only waste power but also beat to such an extent that its size of corncob of overbreak is close with corn kernel, to the separation of seed with clean and bring difficulty.Undue strike effect also can produce detrimental effect to seed, reduces the grade of seed.
Summary of the invention: the purpose of this utility model provides a kind of problem that exists at traditional corn machine and the novel corn thresher cylinder developed
Above-mentioned purpose realizes by following technical scheme:
The novel corn thresher cylinder; its composition comprises: cylinder; be installed in the end plate of described cylinder both sides; described cylinder section is a polygonal; described end plate is vertically fixed on the drum shaft; described end plate and spike-tooth seat, closure plate are formed the closed cylinder housing, on the described spike-tooth seat spike-tooth are housed.
Above-mentioned novel corn thresher cylinder, described end plate are polygonal, and described spike-tooth is in the line arrangement in the shape of a spiral of cylinder periphery.
This technical scheme has following beneficial effect:
1. the utility model is the closed cylinder of polygonal, is characterized in that the cross section of cylinder is polygonal, and spike-tooth is positioned on polygonal summit.
2. when cylinder rotates in the course of the work, the outer surface of cylinder and the gap between the notch board are in the cyclic process of constantly changing from small to big, thereby make the corncob that is in the cylinder produce wriggling each other, increased between them and they and cylinder and notch board between kneading action, helping seed comes off from fringe, reduced the fragmentation of corncob, reduced infringement, improved the grade of seed seed.
Description of drawings: accompanying drawing 1 is a structural representation of the present utility model.
Accompanying drawing 2 is left views of accompanying drawing 1.
Embodiment:
Embodiment 1:
The novel corn thresher cylinder; its composition comprises: cylinder 6; be installed in the end plate 4 of described cylinder 6 both sides; described cylinder section is a polygonal; described end plate 4 is vertically fixed on the drum shaft 5; described end plate 4 is formed the closed cylinder housing with spike-tooth seat 2, closure plate 3, on the described spike-tooth seat 2 spike-tooth 1 is housed.
Embodiment 2:
Above-mentioned novel corn thresher cylinder, described end plate 4 is a polygonal, described spike-tooth 1 is in the line arrangement in the shape of a spiral of cylinder 6 peripheries.
Above-mentioned novel corn thresher cylinder; its course of work is: when cylinder rotates; the outer surface of cylinder and the gap between the notch board are in the cyclic process of constantly changing from small to big; thereby make the corncob that is in the cylinder produce wriggling each other; increased between them and they and cylinder and notch board between kneading action, seed is come off from fringe.
