Abstract
The invention discloses a trapezoidal upper cover of threshing cylinder. The upper cover of threshing cylinder is mainly applied to an axial-flow type combine harvester and thresher and composed of a trapezoidal shell and a feed, wherein the trapezoidal shell is a trapezoid with narrow top and wide bottom and composed of straight lines and oblique lines; the space formed by the trapezoidal shell is larger than that formed by the traditional arc shell so that the space for separating straw and seeds is bigger and the straw can be completely fluffed out; under the centrifugal force generated by the high-speed rotation of the threshing cylinder, the straw and seeds are completely separated; multiple feeds are arranged in the trapezoidal shell; and with certain inclination angle, the feeds have a function of pushing crops backwards. Through the trapezoidal upper cover of threshing cylinder, the space for separating straw and seeds is increased, the straw and seeds can be effectively separated, the rate of straw carrying grain is effectively reduced, and the burden on the threshing cylinder is reduced.
Description
Affiliated technical field
This patent relates to a kind of good separating effect, wraps up on the few trapezoidal threshing cylinder of grain to cover, and is mainly used in axial-flow combine harvester and the thresher.
Background technology
At present; Existing axial-flow combine harvester or thresher, cover all is a circular arc type on their threshing cylinder, the deficiency that cover exists on the circular arc type is: straw and seed separated space are little; Straw is bulk opening fully; Poor with the separating power of seed, thus straw to wrap up in the grain rate higher, the percent of loss of crop is high.
Summary of the invention
Little in order to overcome existing combine straw and seed separated space; Straw is wrapped up in the high problem of grain rate, and the purpose of this patent is will provide on a kind of trapezoidal threshing cylinder to cover, and it can make the separated space of straw and seed strengthen; Straw can be fully bulk; Seed and straw can be separated fully, thereby effectively solve the problem that straw is wrapped up in grain, and can reduce the load of threshing cylinder.
It is that cover is made up of trapezoidal housing and feed on this trapezoidal threshing cylinder that this patent solves the technical scheme that its technical problem adopted.Trapezoidal housing be by straight line and oblique line constitute up-narrow and down-wide trapezoidal; The space that trapezoidal housing forms strengthens the separated space of straw and seed greater than the space that the traditional round arc shell forms, and straw is bulk opening fully; Under the action of centrifugal force that the threshing cylinder high speed rotating produces; Straw is separated with seed fully, solved the problem that straw is wrapped up in grain, also can reduce the load of threshing cylinder.Trapezoidal enclosure interior is provided with several feeds, and each feed is parallel to each other, and feed has certain angle of inclination, plays the effect that pushes crop backward.The direction of threshing cylinder rotation is different, and the incline direction of feed also is different.
The beneficial effect of this patent is, increased the separated space of straw and seed, can effectively reduce straw and wrap up in the grain rate, reduces the threshing cylinder load.
Description of drawings
Below in conjunction with accompanying drawing and embodiment this patent is described further.
Accompanying drawing 1 is the embodiment sketch map of this patent.
Accompanying drawing 2 is embodiment vertical views of this patent.
In the accompanying drawing 1, trapezoidal housing, 2, oblique line, 3, straight line, 4, space one, 5, circular arc housing, 6, space two, 7, feed, 8, the angle of inclination.
Embodiment
Trapezoidal housing 1 be by oblique line 2, straight line 3 constitute up-narrow and down-wide trapezoidal, the space 1 that trapezoidal housing 1 constitutes makes the separated space increasing of straw and seed greater than the space 26 that circular arc housing 5 constitutes.Trapezoidal housing 1 interior welds has several feeds 7, and each feed 7 is parallel to each other, and feed 7 has certain angle of inclination 8, is convenient to push backward crop.Difference according to the threshing cylinder direction of rotation; The incline direction of feed 7 is also different, and the threshing cylinder direction of rotation is that counterclockwise the incline direction of feed 7 is shown in accompanying drawing 3; It is when if the threshing cylinder direction of rotation is clockwise direction, in the opposite direction shown in the incline direction of feed 7 and the accompanying drawing 3.
Claims (2)
1. cover on a trapezoidal threshing cylinder; Comprise trapezoidal housing (1) and feed (7); It is characterized in that trapezoidal housing (1) be by oblique line (2) and straight line (3) form up-narrow and down-wide trapezoidal; The space two (6) that the space one (4) that trapezoidal housing (1) forms forms greater than circular arc housing (5), trapezoidal housing (1) inside is provided with several feeds (7).
2. cover on the trapezoidal threshing cylinder as claimed in claim 1, it is characterized in that each feed (7) is parallel to each other, feed (7) has certain angle of inclination (8), and the threshing cylinder direction of rotation is different, and the incline direction of feed (7) also is different.
