[0030] Example 1

[0031] The present embodiment is an external secondary impurity removal and cleaning device, which is mainly used for large-sized harvesters. It avoids the centralized arrangement of the cleaning device on the harvester and divides the cleaning device into two cleaning mechanism parts, which avoids the bracts from getting stuck in the machine and also makes the bract processing capacity larger. The present embodiment includes a primary bract removal and cleaning mechanism 1 and a secondary bract removal and cleaning mechanism 2 which is vertically matched with the primary bract removal and cleaning mechanism 1. During installation, the primary bract removal and cleaning mechanism 1 is arranged horizontally and the secondary bract removal and cleaning mechanism 2 is arranged vertically, wherein the feeding end of the bract is the head end or the leading end, and the end of the primary bract removal and cleaning mechanism 1 is aligned with the head end of the secondary bract removal and cleaning mechanism 2, wherein the primary bract removal and cleaning mechanism 1 includes a peeling The peeling frame 6 has a primary cleaning sieve plate at the lower end, and the primary cleaning sieve plate has sieve holes so that the grains on the bracts can pass through the sieve holes, but the bracts cannot pass through. A primary cleaning agitator 3 is hingedly installed in the peeling frame 6, and the primary cleaning agitator 3 is arranged above the primary cleaning sieve plate, and a primary cleaning grain collecting agitator 7 is arranged below the primary cleaning sieve plate. Specifically, the primary cleaning agitator 3 includes at least two. For example, in this embodiment, the number of primary cleaning agitators 3 is 2, and the 2 agitators are arranged in parallel. The primary cleaning sieve plate is a plurality of arc-shaped plates connected together. The number of arc-shaped plates is the same as the number of primary cleaning agitators 3, which is also 2 in this embodiment, so that after the bracts enter the primary cleaning agitator 3, the primary cleaning agitator 3 can come into contact with the bracts. The peeling frame 6 is touched and pushes the bracts, and a primary collecting support frame is installed at the lower end of the peeling frame 6. The primary impurity removal auger 3 is hingedly installed on the primary collecting support frame. The lower end of the primary collecting support frame is an arc-shaped plate. The primary collecting support frame surrounds a cavity where the primary cleaning grain collecting auger 7 is located. After the grains fall into the cavity, the primary cleaning grain collecting auger 7 pushes the grains to move. The bract secondary impurity removal and cleaning mechanism 2 includes a fixed frame, and a secondary impurity removal auger 4 is hingedly installed in the fixed frame. The primary impurity removal auger 3 and the secondary impurity removal auger 4 are arranged vertically, that is, the primary impurity removal auger 3 is arranged horizontally, and the secondary impurity removal auger 4 is arranged longitudinally. The longitudinal direction in this embodiment refers to the direction along the fuselage, that is, from the harvester's cutting table to the silo. The lower end of the fixed frame is a secondary cleaning screen plate. A secondary cleaning grain collecting auger 5 is arranged below the cleaning sieve plate, and the cavity where the secondary cleaning grain collecting auger 5 is located is connected to the cavity where the primary cleaning grain collecting auger 7 is located. Specifically, a secondary collecting support frame is installed at the lower end of the fixed frame, and the secondary cleaning auger 4 is hingedly installed on the secondary collecting support frame. The lower end of the secondary collecting support frame is an arc-shaped plate, and the secondary collecting support frame surrounds the cavity where the secondary cleaning grain collecting auger 5 is located. When the bracts pass through the secondary cleaning auger 4, the grains enter the cavity where the secondary cleaning grain collecting auger 5 is located through the sieve holes of the secondary cleaning sieve plate, and then the grains enter the cavity where the primary cleaning grain collecting auger 7 is located. The cavity where the primary cleaning grain collecting auger 7 is located is connected to a grain elevator 9, and the grain elevator 9 is connected to a grain collecting bucket 8.The grains enter the grain elevator 9 along the primary cleaning grain collecting auger 7, and the grain elevator 9 transfers the grains to the grain collecting bucket 8.

[0032] In addition, a protective shell is installed on the upper part of the fixed frame, and the protective shell is arranged above the end of the secondary debris removal auger 4. A gradient shell is installed at the front end of the protective shell. From the front end to the end of the gradient shell, the cavity size of the gradient shell gradually decreases, which is convenient for the entry of bracts and prevents the bracts from leaking out of one side of the fixed frame. The bracts fall into the farmland or the collection bag in a straight line after passing through the protective shell. The protective shell also protects the secondary debris removal auger 4 and the secondary cleaning grain collection auger 5 outside the harvester.

[0033] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.

[0034] Although the above describes the specific implementation methods of the present application in conjunction with the accompanying drawings, it is not intended to limit the scope of protection of the present application. Technical personnel in the relevant field should understand that on the basis of the technical solution of the present application, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the scope of protection of the present application.
