Abstract
The utility model provides a secondary threshing drum of an efficient corn thresher and mainly solves the problem that a threshing drum of an existing corn thresher is low in threshing efficiency. The secondary threshing drum of the efficient corn thresher is characterized in that a corn cob outlet is arranged on the left end of the secondary threshing drum (1) which is provided with sieve pores. The secondary threshing drum (1) is fixed on the upper portion of a main frame. A secondary threshing roller (2) is rotatably arranged in the secondary threshing drum (1) in connecting mode. Three rows of curved stabs (3) are arranged on the secondary threshing roller (2) in the axial direction and intersect with each other. The secondary threshing drum (1) is communicated with the inside of the right end of a primary threshing drum. A shaft of the secondary threshing roller (2) in the left end of the secondary threshing drum (1) is connected with secondary blades (4) which can generate discharging wind power. The right end of the secondary threshing drum (1) is a closed body. The secondary threshing roller (2) is connected with a power source through belt pulleys and a belt. The secondary threshing drum of the efficient corn thresher has the advantage of high threshing efficiency.
Description
Technical field
The utility model relates to a kind of thresher, especially the secondary thrashing cylinder of high efficiency corn thresher.
Background technology
The effect of husker sheller is that iblet is separated with corn ear.And existing husker sheller thrashing cylinder is put because there is the low problem of threshing efficiency in reasons in structure, affects farmers' income.
Summary of the invention
In order to solve the existing low problem of husker sheller thrashing cylinder threshing efficiency.The utility model provides a kind of high efficiency corn thresher secondary thrashing cylinder.The secondary thrashing cylinder of this high efficiency corn thresher has the high characteristics of threshing efficiency.
The technical solution of the utility model is: the secondary thrashing cylinder of this high efficiency corn thresher comprises secondary thrashing cylinder and auxiliary threshing roll.Secondary thrashing cylinder left end has the corn ear of going out mouth, on secondary thrashing cylinder, sieve aperture is arranged, secondary thrashing cylinder is fixed on body frame top, auxiliary threshing roll is rotatably connected in secondary thrashing cylinder, be connected in the song thorn that axially has 3 rows to intersect on auxiliary threshing roll, secondary thrashing cylinder and main thrashing cylinder right-hand member, be connected with the back blades that produces discharge wind-force in secondary thrashing cylinder left end on the auxiliary threshing roll axle, secondary thrashing cylinder right-hand member is obturator, and auxiliary threshing roll is connected with power source with belt by belt pulley.
Song thorn in such scheme is reverse U shape.
The utlity model has following beneficial effect: the secondary thrashing cylinder of this high efficiency corn thresher is owing to adopting secondary thrashing cylinder left end that the corn ear of going out mouth is arranged; on secondary thrashing cylinder, sieve aperture is arranged; secondary thrashing cylinder is fixed on body frame top; auxiliary threshing roll is rotatably connected in secondary thrashing cylinder; the song thorn that axially has 3 rows to intersect on auxiliary threshing roll; be connected in secondary thrashing cylinder and main thrashing cylinder right-hand member; be connected with on the auxiliary threshing roll axle in secondary thrashing cylinder left end and produce the back blades of discharging wind-force, secondary thrashing cylinder right-hand member is optimizing structure of obturator.Utilize song thorn on auxiliary threshing roll to coordinate with secondary thrashing cylinder and realize efficient threshing and Preliminary screening, and then the raising threshing efficiency.The secondary thrashing cylinder of this high efficiency corn thresher has the high characteristics of threshing efficiency thus.
Description of drawings
Accompanying drawing 1 is the utility model structural representation;
Accompanying drawing 2 is Fig. 1 left views.
The secondary thrashing cylinder of 1-in figure, 2-auxiliary threshing roll, the bent thorn of 3-, 4-back blades.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
Shown in accompanying drawing, the secondary thrashing cylinder of this high efficiency corn thresher comprises secondary thrashing cylinder 1 and auxiliary threshing roll 2.Secondary thrashing cylinder 1 left end has the corn ear of going out mouth, and the corncob cellulose after threshing is discharged secondary thrashing cylinder 1 by going out the corn ear mouth.On secondary thrashing cylinder 1, sieve aperture is arranged, the sieve aperture on secondary thrashing cylinder 1 carries out Preliminary screening with core and the large impurity of corn ear, and after screening, iblet drops on upper sieve plate through sieve aperture, and sieve aperture plays first screening effect.Secondary thrashing cylinder 1 is fixed on body frame top, and auxiliary threshing roll 2 is rotatably connected in secondary thrashing cylinder 1, the song thorn 3 that axially has 3 rows to intersect on auxiliary threshing roll 2, and the some bent thorns 3 of every row, bent thorn 3 be reverse U shape, stings 3 by song and coordinates with secondary thrashing cylinder 1 and realize the secondary threshing.Be connected in secondary thrashing cylinder 1 and main thrashing cylinder right-hand member, make the corn ear of the interior threshing of main thrashing cylinder can enter into secondary thrashing cylinder 1.Be connected with on auxiliary threshing roll 2 axles in secondary thrashing cylinder 1 left end and produce the back blades 4 of discharging wind-force, produce blowing power by back blades 4, the corncob cellulose after the secondary threshing is discharged secondary thrashing cylinder 1.Secondary thrashing cylinder 1 right-hand member is obturator.Auxiliary threshing roll 2 is connected with power source with belt by belt pulley, power source mutually tractor power take-off, diesel engine and motor any, provide rotational power by power source for auxiliary threshing roll 2.
The secondary thrashing cylinder of this high efficiency corn thresher adopts bent thorn 3 to coordinate with secondary thrashing cylinder 1 and realizes the secondary threshing, and then improves threshing efficiency, and threshing efficiency reaches per hour more than 40 tons, so be referred to as the secondary thrashing cylinder of high efficiency corn thresher.That the secondary thrashing cylinder of this high efficiency corn thresher is applicable to belt leather and the corn ear of belt leather not.
Claims (2)
1. the secondary thrashing cylinder of a high efficiency corn thresher, comprise secondary thrashing cylinder (1) and auxiliary threshing roll (2), it is characterized in that: secondary thrashing cylinder (1) left end has the corn ear of going out mouth, on secondary thrashing cylinder (1), sieve aperture is arranged, secondary thrashing cylinder (1) is fixed on body frame top, auxiliary threshing roll (2) is rotatably connected in secondary thrashing cylinder (1), the song thorn (3) that axially has 3 rows to intersect on auxiliary threshing roll (2), be connected in secondary thrashing cylinder (1) and main thrashing cylinder right-hand member, be connected with on auxiliary threshing roll (2) axle in secondary thrashing cylinder (1) left end and produce the back blades (4) of discharging wind-force, secondary thrashing cylinder (1) right-hand member is obturator, auxiliary threshing roll (2) is connected with power source with belt by belt pulley.
