Abstract
The utility model provides a full-feed type combine harvester threshing cylinder comprising a screw guide plate. A polygonal threshing cylinder is arranged at the rear of the screw guide plate through a rotating shaft; the rotating shaft penetrates the screw guide plate and the polygonal threshing cylinder. The polygonal threshing cylinder is a concave-convex alternated polygon; teeth are arranged on the convex edges so that a toothed ring is formed; the concave edges are internal ribs. The full-feed type combine harvester threshing cylinder has the advantages that the capacity of a threshing cavity is increased greatly, load of the cylinder and the threshing cavity is lowered, beat frequency is constant, and the possibility of grain breakage is reduced; as the teeth are adjustable, gap between the teeth and concave filter screens can be adjusted flexibly, straws are not easy to twine on the threshing cylinder but can be conveyed to the rear of the threshing cavity more smoothly, damages to machine due to straws twining on the threshing cylinder are avoided, threshing effect of grains in the threshing cavity can be improved greatly, and thus, harvesting efficiency is increased and impurity content, loss rate and breakage rate are all reduced.
Description
Technical field
The utility model relates to full-feeding combine harvester field, specifically a kind of full-feeding combine harvester threshing cylinder.
Background technology
At present both at home and abroad the threshing cylinder of combine mainly contains two kinds, closed cylinder and frame-type cylinder, closed cylinder is mainly reflected in the type such as half-feeding harvester and the full feeding longitudinal axial stream of Jing Guan grain header, closed cylinder advantage is: straw can not enter in cylinder framework, in threshing cavity, impact number of times constant, so percentage of damage less that straw is interrupted, percentage of impurity is lower, broken grass separates with seed is easy, closed cylinder shortcoming is: the gap of filter screen and threshing drum is consistent and can not regulate, in the de-crop of difficulty, cannot regulate the gap of filter screen and cylinder tooth will occur cylinder overload, threshing is unclean, even cause machine breakdown, frame-type threshing cylinder is mainly reflected in 688 series models of Kubo field, its advantage is: straw can enter in cylinder framework, threshing cavity volume is large, cylinder and threshing chamber load are lighter, through threshing, shortcoming is: it is too much that straw impacts number of times in cylinder, causes cereal percentage of damage, percentage of impurity and percent of loss high.
Summary of the invention
The utility model is large for existing domestic and international full-feeding combine harvester thresher drum operating load; in the time of the rice and wheat crops of high-yield field, cannot reach very low percentage of impurity, percent of loss and percentage of damage; a kind of full-feeding combine harvester threshing cylinder of special proposition, makes rice and wheat crops can reach best Threshing.
For this reason, the technical solution of the utility model is: a kind of full-feeding combine harvester threshing cylinder, comprise that spiral imports plate, it is characterized in that: import plate to being provided with a polygon threshing cylinder by a rotating shaft below at spiral, rotating shaft runs through spiral and imports plate and polygon threshing cylinder, and this polygon threshing cylinder is a polygon that convex-concave is alternate, and chimb is provided with tooth plate outward, make it to form an annular gear ring, concave edge is inner reinforced plate.
Improvement to such scheme is: polygon threshing cylinder is hexagon.
Improvement to such scheme is: between the chimb of tooth plate and tooth plate, be provided with adjusting support.
Improvement to such scheme is: the concave edge of inner reinforced plate is provided with v shape cover plate outward.
Improvement to such scheme is: the outside of polygon threshing cylinder is also provided with anti-tangle winding board and is applied in together by rotating shaft.
Beneficial effect:
Threshing cylinder profile of the present utility model is concavo-convex, can effectively increase threshing cavity capacity, and being provided with of tooth plate is beneficial to threshing.
Hexagonal threshing cylinder make straw in threshing cavity to impact number of times constant, be not prone to cereal fragmentation.
Regulate support setting party regulate the height of tooth plate, the gap of flexible modulation tooth plate and notch board filter screen.
The setting of v shape cover plate prevents that grain from calling in threshing cylinder inside.
Arranging of anti-tangle winding board ensured the stable of threshing cylinder.
The utility model has effectively increased the capacity of threshing cavity, cylinder and threshing chamber load are lighter, impact number of times constant, be not prone to cereal fragmentation, its tooth plate is adjustable, can flexible modulation tooth plate and the gap of notch board filter screen, make rice stalk be not easy to be wrapped on threshing cylinder, rice stalk is carried backward more unimpeded in threshing cavity, avoid rice stalk to be wound around machine is caused to damage, thereby make cereal in threshing cavity, obtain obtaining Threshing more fully, improve harvesting efficiency, reduce percentage of impurity, percent of loss and percentage of damage.

Fig. 1 is main TV structure schematic diagram of the present utility model.
Fig. 2 is that the A-A of Fig. 1 is to schematic cross-section.
Fig. 3 is the enlarged diagram that Fig. 2 is ordered at B.
In figure, 1 is that spiral imports plate, the 2nd, and hexagon threshing cylinder, the 3rd, rotating shaft, the 4th, tooth plate, the 5th, chimb, the 6th, concave edge, the 7th, regulate support, the 8th, anti-tangle winding board, the 9th, v shape cover plate.
Embodiment
As shown in Figure 1, 2, 3 of the present utility model.
A kind of full-feeding combine harvester threshing cylinder, comprise that spiral imports plate 1, import plate 1 to being provided with a hexagon threshing cylinder 2 by a rotating shaft 3 below at spiral, rotating shaft 3 runs through spiral and imports plate 1 and hexagon threshing cylinder 2, this hexagon threshing cylinder 2 is the polygons that convex-concave is alternate, chimb 5 is outer is provided with tooth plate 4, makes it to form an annular gear ring, and concave edge 6 is inner reinforced plates.
Between the chimb 5 of tooth plate 4 and tooth plate 4, be provided with and regulate support 7.
The outer v shape cover plate 9 that is provided with of concave edge 6 of inner reinforced plate.
The outside of hexagon threshing cylinder 2 is also provided with anti-tangle winding board 8 and is applied in together by rotating shaft 3.
