Abstract
The invention provides a negative pressure type impurity removing machine for wheat, and relates to a machine for removing impurities from grain. The negative pressure type impurity removing machine for wheat comprises a machine frame, a screening barrel and a motor, wherein the machine frame is provided with roller wheels, the screening barrel is clamped and supported by the roller wheels which are fixed on the machine frame, the roller wheels are symmetrically arranged at two sides of the screening barrel, the roller wheels at the same side are connected to each other through a connecting shaft, the motor is fixed on the machine frame, and is connected with the roller wheels at one side of the screening barrel through a belt and a belt pulley, the screening barrel is composed of three layers of coaxial meshed rollers which are fixed through brackets, a charging opening is connected to an opening of the first-layer roller, a dust collecting opening is arranged at the tail end of the second-layer roller, the dust collecting opening is connected with a mesh type gas-material separator and a negative-pressure generator through exhaust pipes, the mesh type gas-material separator is installed on the machine frame, three layers of discharging openings are also correspondingly arranged at the tail ends of the three layers of rollers respectively, the screening barrel is sloped, and the end of the charging opening is higher than the end of the discharging openings. The negative pressure type impurity removing machine for wheat is simple to operate, is convenient to use, and cannot occupy a large space; and tiny dust and straws can be sucked by the negative pressure generator, so that air pollution can be prevented, and the quality of a working environment can be improved.
Description
Technical field
The present invention relates to a kind of machine for removing impurity of grain, specifically a kind of negative-pressure impurity removing machine for wheat.
Background technology
At present clear assorted many employings of wheat are winnowed, the method for air blast screening, winnow and place larger place assorted clearly to the screening of large grain are methods faster, but impurity gravity reason impurity elimination precision is not high owing to winnowing, the air blast screening is to staff's heavy contamination, and condition of work is relatively poor.
Summary of the invention
The object of the present invention is to provide a kind of negative-pressure impurity removing machine for wheat, solve the above problems.
The technical solution adopted for the present invention to solve the technical problems is: negative-pressure impurity removing machine for wheat, it is characterized in that, comprise frame, screen drum and motor with roller, described screen drum props up by the roller card that is fixed on the frame, the roller symmetry be positioned at the screen drum both sides, the roller of homonymy connects by connecting axle; Motor is fixed on the frame, is connected with the roller of belt pulley with screen drum one side by belt; Described screen drum is made of the three-layer network shape cylinder of concentric, extremely be respectively ground floor cylinder, second layer cylinder and the 3rd layer of cylinder in having outward, fix by support between three layers of cylinder, the tube port position of ground floor cylinder connects charging aperture, the end of second layer cylinder is provided with a dust collecting opening, dust collecting opening links to each other with negative pressure generator with rack-mounted net cover type gas thing separator by exhaust tube, and the end of corresponding ground floor cylinder, second layer cylinder and the 3rd layer of cylinder also is respectively equipped with the first feed opening, the second feed opening and the 3rd feed opening; Described screen drum is skewed, and feed inlet end is higher than discharge port end.
The invention has the beneficial effects as follows: by three layers of screen drum wheat and foreign material are separated, simple to operate, easy to use, and do not take significantly side, small dust and stalk siphon away by negative pressure generator, air are not polluted, and improve the working environment quality.
Description of drawings
Fig. 1 is structural representation of the present invention,
Fig. 2 is top view of the present invention.
Among the figure: 1 negative pressure generator, 2 frames, 3 charging apertures, 4 net cover type gas thing separators, 5 exhaust tubes, 6 dust collecting opening, 7 first feed openings, 8 second feed openings, 9 the 3rd feed openings, 10 rollers, 11 motors, 13 ground floor cylinders, 14 second layer cylinders, 15 the 3rd layers of cylinder
The specific embodiment
Such as Fig. 1, shown in Figure 2, negative-pressure impurity removing machine for wheat comprises frame 2, screen drum and motor 11 with roller, and described screen drum is by being fixed on roller 10 card on the frame 2, roller 10 symmetries be positioned at the screen drum both sides, the roller 10 of homonymy connects by connecting axle; Motor 11 is fixed on the frame 2, is connected with the roller 10 of belt pulley with screen drum one side by belt; Described screen drum is made of the three-layer network shape cylinder of concentric, extremely be respectively ground floor cylinder 13 in having outward, second layer cylinder 14 and the 3rd layer of cylinder 15, fix by support between three layers of cylinder, the tube port position of ground floor cylinder 13 connects charging aperture 3, the end of second layer cylinder 14 is provided with a dust collecting opening 6, dust collecting opening 6 links to each other corresponding ground floor cylinder 13 by exhaust tube 5 with net cover type gas thing separator 4 on being installed in frame 2 with negative pressure generator 1, the end of second layer cylinder 14 and the 3rd layer of cylinder 15 also is respectively equipped with the first feed opening 7, the second feed opening 8 and the 3rd feed opening 9; Described screen drum is skewed, and feed inlet end is higher than discharge port end.
Start motor 11, driving roller 10 by belt pulley rotates, driving the 3rd layer of cylinder 15 rotates, because ground floor cylinder 13, second layer cylinder 14 and the 3rd layer of cylinder 15 connect as one by support, so ground floor cylinder 13, second layer cylinder 14 and the 3rd layer of cylinder 15 rotate synchronously, after wheat enters from charging aperture 3, arrive first ground floor cylinder 13, because the mesh of ground floor cylinder 13 is larger, to larger stone, weeds, stalk plays a role in filtering, these foreign material are removed by the first feed opening 7, wheat and less foreign material fall into second layer cylinder 14, wheat falls into the 3rd layer of cylinder 15 to less foreign material at this one deck, Exit-edge at second layer cylinder 14, negative pressure occurs by negative pressure generator 1 in dust collecting opening 6, by exhaust tube 5, dust, stalk siphons away, by net cover type gas thing separator 4 dirt, stalk is stayed and is separated in the mesh bag, the less grains of sand fall into the 3rd layer of cylinder 15 by mesh, wheat gushes by the second feed opening 8, falls into the 3rd layer of cylinder 15 less grains of sand and gushes by the 3rd feed opening 8, and whole so clear general labourer does totally to finish efficiently.Particularly particularly short and sweet with the clear general labourer's work of the kind of wheat to experiment, cleaning is simple, is difficult for mixing.
