Abstract
The utility model relates to the field of agricultural machines, in particular to a drill frame sleeve of a corn harvester threshing device. The drill frame sleeve of the corn harvester threshing device is characterized in that the drill frame sleeve comprises a drill sleeve, steel balls and a jackscrew; the middle of the drill sleeve is provided with an inner hole with the diameter a little larger than that of a drill, the two sides of the drill sleeve are respectively provided with two or more steel balls, the steel balls are pressed on the outer surface of the drill or into cutting grooves through the jackscrew, and when the drill extends or retracts in the drill sleeve, the drill rotates due to the fact that the steel balls are clamped into the cutting grooves. The drill frame sleeve is simple in structure, can fix the drill, and can rotate while the drill stretches and retracts.
Description
Technical field
The utility model relates to agricultural machinery field, is specifically related to a kind of corn picker sheller unit drill bit frame cover.
Background technology
Tradition corn picker all only has harvesting function; corn ear is directly entered after gathering in the hopper of machine; but along with the development of mechanization; need corn picker to increase peeling separating mechanism; in sheller unit, threshing drill bit needs automatic telescopic rotation; push rod is only to the flexible power of drill bit below, and rotation realizes by drill bit fixed cover.
Utility model content
For realizing the function of drill bit automatic rotation, the utility model provides a kind of corn picker sheller unit drill bit frame cover.
The technical solution adopted in the utility model is: a kind of corn picker sheller unit drill bit frame cover, is characterized in that comprising drill bushing, steel ball and jackscrew; In the middle of drill bushing, have the endoporus that is a bit larger tham bit diameter, more than two steel ball is respectively installed in drill bushing both sides, with jackscrew, steel ball is pressed in the cutting slot of drill bit outer surface, when drill bit is elastic in drill bushing, because steel ball is stuck in cutting slot, drill bit is rotated along cutting slot rotation direction.
Employing the beneficial effects of the utility model are: the utility model is simple in structure, not only play the effect of fixed drill bit, and are that drill bit is rotated in stretching motion.
Accompanying drawing explanation
Fig. 1 cutaway view of the present utility model.
Reference numeral: 1-drill bushing, 2-steel ball, 3-jackscrew, 4-drill bit.
Embodiment
A corn picker sheller unit drill bit frame cover as shown in Figure 1, is characterized in that comprising drill bushing 1, steel ball 2 and jackscrew 3; In the middle of drill bushing 1, have the endoporus that is a bit larger tham drill bit 4 diameters, more than two steel ball 2 is respectively installed in drill bushing 1 both sides, steel ball 2 is pressed in the cutting slot of drill bit 4 outer surfaces with jackscrew 3, drill bit 4 is interior when elastic at drill bushing 1, because steel ball 2 is stuck in cutting slot, drill bit 4 is rotated along cutting slot rotation direction.
