Abstract
The utility model relates to the technical field of threshing equipment in the agricultural machinery, and discloses a secondary cleaning device used for a threshing machine. The secondary cleaning device used for the threshing machine comprises a machine case (4), a cleaning chamber cover (2), arc-shaped cleaning screen cloth (6) and a cleaning assembly, wherein the cleaning chamber cover (2) is an arc plane plate; one edge of the cleaning chamber cover (2) is hinged to one side edge of the machine case (4) via a hinge mechanism (3); the other edge of the cleaning chamber cover (2) is fixedly arranged on the other side edge of the machine case (4) via a hanging buckle (9); the inner side surface of the cleaning chamber cover (2) is provided with more than two guide sheets (5); the cleaning assembly consists of a cleaning shaft (8), more than two cleaning harrow nails (7) and two cleaning shaft bearing pedestals (10); the cleaning harrow nails (7) are installed on the cleaning shaft (8) in a staggered mode; two ends of the cleaning shaft (8) are penetrated through the cleaning shaft bearing pedestals (10); the arc-shaped cleaning screen cloth (6) is installed below the cleaning shaft (8) in the inner cavity of the machine case (4). The detention time of impurities, such as particle-contained broken spikes or broken straws and millet leaves, in a threshing chamber is shortened, so that the roller threshing efficiency is improved, and waste caused by that the impurities are discharged by carrying grain can be avoided.
Description
Technical field
The utility model relates to the secondary cleaning plant that the threshing apparatus technical field in agricultural machinery, particularly a kind of thresher are used.
Background technology
Existing paddy rice or wheat thresher; although be provided with secondary threshing operation,, great majority do not arrange special secondary separating mechanism; for remaining containing foreign material such as the disconnected fringe of grain or disconnected rice straw and standing grain leaves after threshing and screening, just turn back to and in threshing roller, carry out secondary threshing.So, naturally just extended containing the holdup time of foreign material in threshing cavity such as the disconnected fringe of grain or disconnected rice straw and standing grain leaves, thereby reduced the threshing efficiency of roller, when serious, can cause the foreign material grain of carrying under one's arms to arrange outward, caused waste.
Summary of the invention
The purpose of this utility model is to provide a kind of cleaning plant that can improve threshing efficiency, cut the waste.
For achieving the above object, technical solution adopted in the utility model is the secondary cleaning plant used of a kind of thresher of design: comprise cabinet 4, clean chamber cap 2, arc is cleaned screen cloth 6 and clean assembly;
A, the described chamber cap 2 of cleaning are for cambered plate, and it be hinge in a side of cabinet 4 on one side by twisting mechanism 3, and another side is by buckling 9 another sides that are fixed on cabinet 4; At the described medial surface of cleaning chamber cap 2, the prerotation vane 5 also having more than two is installed;
B, the described assembly of cleaning are above clean harrow nail 7 and two and clean bearing housing 10 and form by cleaning axle 8 and two, clean harrow nail 7 and are staggered installation of and are cleaning on axle 8, and the two ends of cleaning axle 8 install cleans bearing housing 10;
C, described arc clean screen cloth 6 be arranged in cabinet 4 inner chambers, clean axle 8 below.
Described in being arranged on, cleaning the prerotation vane 5 of chamber cap 2 medial surfaces arranges in the shape of a spiral.
At the described tail end of cleaning chamber cap 2, be also provided with impurity discharging port 1.
The secondary cleaning plant that thresher of the present utility model is used, that the second cleaning mechanism cleaning screen cloth by arc and clean module composition is set in the threshing cabinet of thresher, the harrow nail of cleaning that utilization is cleaned in assembly is stirred containing foreign material such as the disconnected fringe of grain or disconnected rice straw and standing grain leaves and is moved on the net at arc sorting screen, crumple, gone up contained grain and carried out secondary threshing, both reduced containing the holdup time of foreign material in threshing chamber such as the disconnected fringe of grain or disconnected rice straw and standing grain leaves, and then improved the threshing efficiency of roller, reduced again and arranged caused waste outward because of the foreign material grain of carrying under one's arms.
Accompanying drawing explanation
Accompanying drawing 1 is that master of the present utility model looks schematic diagram.
In figure: the 1st, impurity discharging port, the 2nd, clean chamber cap, the 3rd, twisting mechanism, the 4th, cabinet, the 5th, prerotation vane, the 6th, arc is cleaned screen cloth, and the 7th, clean harrow nail, the 8th, clean axle, the 9th, buckle, the 10th, clean bearing housing.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described.Explanation is below to adopt the mode exemplifying, but protection domain of the present utility model should not be limited to this.
The present embodiment is by cabinet 4, clean chamber cap 2, arc is cleaned screen cloth 6 and cleans module composition, clean assembly and be that above (this example is set to 20 by cleaning axle 8 and two, also can adopt other quantity) clean harrow nail 7 and two clean bearing housing 10 and form, clean harrow nail 7 and be staggered installation of and cleaning on axle 8, form " mace " shape; The two ends of cleaning axle 8 install cleans bearing housing 10, and two is cleaned bearing housing 10 and is arranged in cabinet 4 machine frame at two sides; The one end of cleaning axle 8 passes cleans bearing housing 10, then belt pulley or gear are installed, to introduce power.
Clean chamber cap 2 for cambered plate, its medial surface is installed the prerotation vane 5 that also has two above (this example is set to 5, also can adopt other quantity), arranges in the shape of a spiral; The one side of cleaning chamber cap 2 be hinge in a side of cabinet 4 by twisting mechanism 3, another side is by buckling 9 another sides that are fixed on cabinet 4; At the tail end of cleaning chamber cap 2, be also provided with impurity discharging port 1.
Arc clean screen cloth 6 be arranged in cabinet 4 inner chambers, clean axle 8 below, its upper cavity forms cleaning room.
During use, remaining containing foreign material such as the disconnected fringe of grain or disconnected rice straw and standing grain leaves after threshing and screening, by side, entered in cleaning room, power is given and is cleaned axle 8 its rotations of drive by belt pulley or gear transmission, the harrow nail 7 cleaned fixed thereon drives and containing foreign material such as the disconnected fringe of grain or disconnected rice straw and standing grain leaves, along arc, cleans screen cloth 6 and rotate, cleaning prerotation vane 5 guiding that chamber cap 2 medial surfaces install in the shape of a spiral moves to the impurity discharging port 1 of cleaning chamber cap 2 tail ends containing foreign material such as the disconnected fringe of grain or disconnected rice straw and standing grain leaves, containing the foreign material such as the disconnected fringe of grain or disconnected rice straw and standing grain leaf rotate and moving process in produce and crumple, grain contained on it is split away off, and fall in the sieve aperture of cleaning screen cloth 6 by arc, be recycled.The foreign material such as the disconnected fringe after threshing or disconnected rice straw and standing grain leaf, are discharged by the impurity discharging port 1 of cleaning chamber cap 2 tail ends.
In use, in cleaning room, because the foreign material such as disconnected fringe or disconnected rice straw and standing grain leaf too much amass while having expired, can open and buckle 9, open and clean chamber cap 2, the foreign material such as the disconnected fringe that taking-up is gathered or disconnected rice straw and standing grain leaf.
The secondary cleaning plant that thresher of the present utility model is used, can threshing paddy, also can threshing wheat; Both can be installed in common thresher and support the use, also can with combine in threshing unit support the use.
