Description
Technical field
The utility model relates to agricultural machine equipment configuration field, is specifically related to a kind of paddy rice screening device.
Background technology
Paddy rice is the one that draft rice belongs to, be also during rice belongs to as the main long one of grain, be also called Asian type cultivated rice. Paddy rice is annual gramineae plant, unifacial leaf, and property happiness is warm and humid, about has 1 to 1.8 meters high time ripe, and leaf is elongated, about has 50 to 100 cm long, wide about 2 to 2.5 centimetres. Spending of rice is very little, and when blooming, main flower fair presents arch, down all can hold little Hua between 30 to 50 centimetres in end of the branch, and major part self-pollination also bears seeds, and becomes spike of rice.
When planting, because impurity, leaf, little stone, iron filings and not plump paddy etc. in seed, if by artificial screening not only inefficiency, and there is the unclean situation of removal of impurities in paddy rice.
Practical novel content
The purpose of this utility model is to provide the paddy rice screening device of a kind of impurity that can effectively remove in paddy rice.
For achieving the above object, the technical solution of the utility model is as follows:
The base case that this scheme provides is: a kind of paddy rice screening device, comprises frame, bent axle, connecting rod and multiple rocking bar, and described frame is provided with screen box; Described frame is provided with back up pad, and described frame side is provided with screening motor, and described screening motor is connected with bent axle, and described connecting rod one end is connected with bent axle, and the other end is connected with support; It is rotationally connected with back up pad in the middle part of described rocking bar; Described rocking bar one end and screen box bottom-hinged, the other end and rod hinge connection; Described screen box has opening for feed and discharge port, in described screen box, is provided with two layer screen net; Being provided with helical screw feeder below described screen cloth, described helical screw feeder one end is connected with feeding motor, and the other end is positioned on discharge port.
Principle of work of the present utility model and useful effect be: screening motor is fixed in frame, screening driven by motor crank rotation, it is rotatably connected in the middle part of rocking bar in the middle part of back up pad, rocking bar one end and screen box bottom-hinged, the other end and rod hinge connection, connecting rod is connected with bent axle, then bent axle drive link can move reciprocatingly thus drive rocking bar to move. Because rocking bar and screen box are hinged, then screen box can be driven to move reciprocatingly when rocking bar moves, paddy rice thus fall from screen cloth. Paddy rice can effectively be screened by the utility model, it is to increase paddy rice screening efficiency. Being provided with spiral feeder below screen cloth, described spiral feeder one end is connected with motor, and the other end is positioned on discharge port, it is possible to smoothly the paddy rice cleaned out is sent to discharge port, is discharged by the paddy rice cleaned out in time, it is to increase removal of impurities screening efficiency.
Preferred version one: based on the preferred version of scheme, described screen cloth is provided with magnet, paddy rice may exist a small amount of iron filings, magnet can adsorb the iron filings in paddy rice, makes screening effect better.
Preferred version two: the preferably preferred version of, described two layer screen net sieve aperture successively decreases from top to bottom, paddy rice first carries out first time screening through the screen cloth that mesh is bigger, then second time screening is carried out through the screen cloth that mesh is less, paddy rice is through twice step-sizing, it is possible to make screening effect better.
Preferred version three, the preferably preferred version of two, described rocking bar quantity is three, and three rocking bars can guarantee screen box and rocking bar stable connection.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model paddy rice screening device embodiment.
Embodiment
Below by embodiment, the utility model is described in further detail:
Reference numeral in Figure of description comprises: frame 10, support bar 11, screen box 20, screen cloth 21, opening for feed 22, discharge port 23, screening motor 30, bent axle 31, connecting rod 32, rocking bar 33, feeding motor 40, spiral send device 41.
Embodiment is substantially as shown in Figure 1: a kind of paddy rice screening device, comprise frame 10, bent axle 31, connecting rod 32 and three rocking bars 33, frame is provided with screen box 20, in frame 10, bolt is connected with back up pad, frame 10 side is provided with screening motor 30, screening motor 30 is connected by belt with bent axle 31, and bent axle 31 is connected with connecting rod 32, is rotationally connected with back up pad in the middle part of rocking bar 33; Rocking bar 33 two ends respectively with screen box 20 bottom and connecting rod 32 hinged; Having opening for feed 22 and discharge port 23 on screen box 20, be welded with two layer screen net 21 in screen box 20, the sieve aperture of two layer screen net 21 successively decreases from top to bottom, it is possible to makes paddy rice through twice screening, makes screening effect better. Containing magnet in screen cloth 21, it is possible to the metal in absorption paddy rice, makes screening effect better. Helical screw feeder 41 it is provided with below screen cloth 21, helical screw feeder 41 one end is connected with feeding motor 40, and the other end is positioned on discharge port 23, it is possible to smoothly the paddy rice cleaned out is sent to discharge port 23, in time the paddy rice cleaned out is discharged, it is to increase removal of impurities screening efficiency.
Motor is fixed in frame 10, driven by motor bent axle 31 rotates, it is rotatably connected in the middle part of rocking bar 33 in the middle part of back up pad, rocking bar 33 one end and screen box 20 bottom-hinged, the other end and connecting rod 32 are hinged, connecting rod 32 is connected with bent axle 31, then bent axle 31 drive link 32 can move reciprocatingly thus drive rocking bar 33 to move. Because rocking bar 33 is hinged with screen box 20, then screen box 20 can be driven to move reciprocatingly when rocking bar 33 moves, paddy rice thus fall from screen cloth 21.
Above-described is only embodiment of the present utility model, and in scheme, the general knowledge such as known concrete structure and characteristic does not do too much description at this. Should be understood that; for a person skilled in the art, under the prerequisite not departing from the utility model structure, it is also possible to make some distortion and improvement; these also should be considered as protection domain of the present utility model, and these all can not affect effect and the practical applicability that the utility model is implemented. The protection domain that this application claims should be as the criterion with the content of its claim, and the embodiment in specification sheets etc. record the content that may be used for explaining claim.
