Abstract
The utility model discloses a shaking board for a combine harvester, which comprises a shaking board frame and step plates, wherein, the step plates are fixed in the shaking board frame, and straw shaking plates are arranged on the step plates at intervals; finger screen strips are fixed at the discharge end of the shaking board frame, and cleaning material dispersing plates are fixed between the adjacent finger screen strips; and straw shaking teeth are arranged on the cleaning material dispersing plates. The cleaning material dispersing plates play the role of prolonging the effective action length of the prior shaking board in a limited space under a limited space and limited constraint conditions, thereby improving the shaking and dispersing effect for agglomerate materials; meanwhile, a plurality of densificated cleaning material dispersing plates like a group of rectification gates, which objectively play the rectifying role for the pre-cleaning air flow, reduce the loss of the eddy current inside the pre-cleaning air flow and improve the separation efficiency of air flow.
Description
Technical field
The utility model relates to a kind of grain combine, relates in particular to the shuttle board of using on a kind of grain combine.
Background technology
The existing axial flow self-propelled grain cbmbine harvester cleaning room shuttle board of cutting is owing to the structure limitation, and general structure length has only 300mm, often has following disadvantage in the operation:
(1) stepped plate length is short, cleans mixture in short-term, trembles inhomogeneously under the short stroke condition, and it is not thorough that difference is cleaned the thing layering yet.
(2) it is strong to cut the effect of axial-flow type drum device, generation clean material tradition cut streaming and under the identical operation condition, be doubled and redoubled, more must improve the shuttle board function.
(3) transverse-axis-flow cylinder working width is generally greater than the cleaning room width, the material of cleaning that cylinder produces must be by after the redistribution of cleaning room width, could throw and give shuttle board, because the farm work condition is ever-changing, be again and join non intelligent dividing, so the material of cleaning that shuttle board receives objectively is uneven.
For these reasons, similar this short shuttle board be we can say and be can't bear the heavy load, and is very limited to the ability and the quality of cleaning the thing shake.Therefore, usually after " processing ", exist the part bulk to clean thing and deliver to compass screen surface, thereby cause that compass screen surface cleans the thing local accumulation,, cause cleaning loss and seed percentage of impurity to exceed standard frequently for follow-up pneumatic jig technology hides some dangers for.
The utility model content
Technical problem to be solved in the utility model provides a kind of can the raising cleaning the combine shuttle board of thing shake ability.
For solving the problems of the technologies described above, the technical solution of the utility model is: the combine shuttle board, comprise the shuttle board framework, be fixed on the stepped plate in the described shuttle board framework, be interval with on the described stepped plate by the original text plate, described shuttle board framework discharge end is fixed with the finger grid bar, is fixed with between the described adjacent finger grid bar and cleans the material dispersion plate, and the described material dispersion plate of cleaning is provided with chaff tooth.
As a kind of improvement, the described tail end of cleaning the material dispersion plate upwarps.
Owing to adopted technique scheme, the combine shuttle board, comprise the shuttle board framework, be fixed on the stepped plate in the described shuttle board framework, be interval with on the described stepped plate by the original text plate, described shuttle board framework discharge end is fixed with the finger grid bar, is fixed with between the described adjacent finger grid bar and cleans the material dispersion plate, and the described material dispersion plate of cleaning is provided with chaff tooth; Clean the effect of material dispersion plate, equal former shuttle board has been prolonged effective interaction length under the confined space, finite constraint condition, thereby improved the diffusing effect of trembling of bulk material; The material dispersion plate of cleaning after some encryptions simultaneously seems one group of honeycomb screen, objectively has concurrently pre-clear air-flow rectified action, reduces the loss of pre-air-flow internal vortex clearly, improves flow separation efficient.
Description of drawings
Accompanying drawing is the structural representation of the utility model embodiment.
Embodiment
As shown in drawings, the combine shuttle board, comprise shuttle board framework 5, be fixed on the stepped plate 1 in the described shuttle board framework 5, be interval with by original text plate 2 on the described stepped plate 1, described shuttle board framework 5 discharge ends are fixed with finger grid bar 3, are fixed with between the described adjacent finger grid bar 3 and clean material dispersion plate 4, and the described material dispersion plate 4 of cleaning is provided with chaff tooth 41.Clean the effect of material dispersion plate, equal former shuttle board has been prolonged effective interaction length under the confined space, finite constraint condition, thereby improved the diffusing effect of trembling of bulk material; The sorting purpose material dispersion plate of cleaning after some encryptions simultaneously seems one group of honeycomb screen, objectively has concurrently pre-clear air-flow rectified action, reduces the loss of pre-air-flow internal vortex clearly, improves flow separation efficient.Evidence, moment forms bulk material waterfall as long as clean that mixture is that dispersed falls compass screen surface, just can reach the satisfied pre-clear effect of air-flow, be that the overwhelming majority is cleaned thing and isolated cleaning room by airflow carrier, thereby greatly alleviate the compass screen surface load, guarantee high-quality screening efficiency and sorting performance index.
The described tail end of cleaning material dispersion plate 4 upwarps, and in conjunction with extensional vibration, will lack cane earlier and evict from, and the step-by-step movement propelling, seed and thin chaff layering leading fall simultaneously, and by in advance clear flow separation, thereafter, dispossessed short cane is blown out cleaning room by pre-clear air-flow in succession.
The described material dispersion plate 4 of cleaning is preferably thin plate about 1mm, when constituting the synchronous extensional vibration of rigid body with shuttle board, and laterally vibration slightly in a measure, thus improved the diffusing effect of trembling of bulk material.
Claims (2)
1. combine shuttle board, comprise shuttle board framework (5), be fixed on the stepped plate (1) in the described shuttle board framework (5), be interval with on the described stepped plate (1) by original text plate (2), described shuttle board framework (5) discharge end is fixed with finger grid bar (3), it is characterized in that: be fixed with between the described adjacent finger grid bar (3) and clean material dispersion plate (4), the described material dispersion plate (4) of cleaning is provided with chaff tooth (41).
2. combine shuttle board as claimed in claim 1 is characterized in that: the described tail end of cleaning material dispersion plate (4) upwarps.
