specific Embodiment approach 1

[0016] Specific implementation mode one: combine figure 1 Describe this embodiment, the combined seal cover of this embodiment comprises front part seal plate 1, front part seal cover shell 2, rear part intermediate seal cover shell 3, rear part seal cover shell 4 on both sides, rear seal Plate 5, a plurality of front guide vanes 6 and a plurality of rear intermediate guide vanes 7, the front sealing cover shell 2 is provided with a residual recovery system interface 8, the front sealing plate 1, the front sealing cover The body 2, the rear middle sealing cover shell 3 and the rear sealing plate 5 are sequentially connected, the sealing cover shells 4 on both sides of the rear part are arranged on both sides of the rear middle sealing cover shell 3, and a plurality of front guide vanes 6 is obliquely arranged on the front seal cover shell 2, and a plurality of rear intermediate guide vanes 7 are obliquely arranged on the rear intermediate seal cover shell 3, and the plurality ...

specific Embodiment approach 2

[0021] Specific implementation mode two: combination figure 1 Describe this embodiment, the left end of each front guide vane 6 of this embodiment is inclined forward, and the included angle between each front guide vane 6 and the horizontal plane is 20°-30°, each rear The left end of the middle guide vane 7 is inclined forward, and the angle between each rear middle guide vane 7 and the horizontal plane is 20°-30°. With such arrangement, multiple front guide vanes 6 make the crops entering at the front end move quickly to the threshing chamber, and reduce the feeding resistance at the front part. Other compositions and connections are the same as in the first embodiment.

specific Embodiment approach 3

[0022] Specific implementation mode three: combination figure 1 Describe this embodiment, have a plurality of long holes 9 for separating grains on the sealing cover casing 4 on both sides of the rear portion of this embodiment. In this way, the rear middle sealing cover housing 3 is divided into three parts in the middle and both sides. The inside of the rear middle sealing cover housing 3 is welded with a fixed rear middle guide vane 7, because it is in the combined sealing cover. The upper part, its angle is not conducive to the grain falling on it, so there is no elongated hole on the rear middle sealing cover shell 3, and the sealing cover shell 4 on both sides of the rear part is processed with long holes that are conducive to the separation of grains 9. When the crops are conveyed backward, the grains that come off will be separated from the long holes 9, which quickly reduces the workload of the open axial flow threshing drum 13 and its lower concave grid screen 14, re...

Abstract

The invention provides a combined type sealing cover and an open-type axial flow threshing system using the same, and relates to sealing covers and open-type axial flow threshing systems. The combined type sealing cover and the open-type axial flow threshing system using the same aim at resolving the problems that a sealing cover in an existing threshing system can not achieve multiple purposes, workload is heavy, and only a single variety of crops can be harvested. A front sealing cover shell of the combined type sealing cover is provided with an impurity and residue recovery system connection port, a front sealing plate, the front sealing cover shell, a rear middle sealing cover shell and a rear sealing plate are connected in sequence, rear two side sealing cover shells are installed on two sides of the rear middle sealing cover shell, a plurality of front guide vanes are installed on the front sealing cover shell in an inclined mode, and a plurality of rear middle guide vanes are installed on the rear middle sealing cover shell in an inclined mode. A chained coupling and a transmission reversing gearbox of the threshing system are sequentially installed at the rear end of at least one set of axial flow threshing device. The combined type sealing cover and the open-type axial flow threshing system using the same are used for threshing the crops.

Description

technical field [0001] The invention relates to a sealing cover and an open axial flow threshing system, in particular to a combined sealing cover and an open axial flow threshing system using the sealing cover. Background technique [0002] The threshing systems of the existing combine harvesters are mostly two types: the tangential flow plus axial flow threshing system and the axial flow threshing system. The tangential flow plus axial flow threshing system is on the verge of being eliminated due to backward technology. Most of the systems, cutting flow plus axial flow threshing system was used earlier, because of the single harvest variety and high crushing rate, it can no longer keep up with the development requirements of modern agriculture. The closed axial flow threshing system is the cutting On the basis of the fed-flow axial flow threshing system, the threshing system was developed by removing the tangential flow drum and lengthening the original separation drum. Ho...
