Description

Negative pressure wheat cleaning machine

technical field

The invention relates to a grain cleaning machine, in particular to a negative pressure wheat cleaning machine.

Background technique

At present, the cleaning of wheat mostly adopts the method of raising field and blowing wind to screen, and raising field is a faster method for screening and cleaning bulk grains and places with large fields, but due to the gravity of impurities when raising the field, the accuracy of removing impurities is not good. High, the blower screening will cause serious pollution to the staff, and the working conditions are poor.

Contents of the invention

The purpose of the present invention is to provide a negative pressure wheat cleaning machine to solve the above problems.

The technical solution adopted by the present invention to solve the technical problems is: a negative pressure wheat cleaning machine, which is characterized in that it includes a frame with rollers, a sieve cylinder and a motor, and the sieve cylinder passes through the rollers fixed on the frame. The rollers are symmetrically located on both sides of the screen cylinder, and the rollers on the same side are connected by connecting shafts; the motor is fixed on the frame and connected to the rollers on one side of the screen cylinder through belts and pulleys; The three-layer mesh roller is composed of three-layer mesh rollers, which are the first layer roller, the second layer roller and the third layer roller from the inside to the outside. The three-layer rollers are fixed by brackets, and the mouth of the first layer roller is connected to the feed port There is a dust collection port at the end of the second layer of drum, and the dust collection port is connected with the net cover type gas-material separator and negative pressure generator installed on the frame through the exhaust pipe, corresponding to the first layer of drum, the second layer of drum and the The end of the third drum is also provided with a first discharge port, a second discharge port and a third discharge port respectively; the sieve cylinder is inclined, and the feed port end is higher than the discharge port end.

The beneficial effects of the present invention are: the wheat is separated from sundries through the three-layer sieve cylinder, the operation is simple, the use is convenient, and it does not occupy a large space, the tiny dust and straw are sucked away by the negative pressure generator, and the air is not polluted. Improve the quality of the working environment.

Detailed ways

As shown in Fig. 1 and Fig. 2, the negative pressure type wheat cleaning machine includes a frame 2 with rollers, a sieve cylinder and a motor 11, and the described sieve cylinder is clamped by a roller 10 fixed on the frame 2, and the roller 10 are symmetrically located on both sides of the screen drum, and the rollers 10 on the same side are connected by connecting shafts; the motor 11 is fixed on the frame 2, and is connected with the rollers 10 on one side of the screen drum through belts and pulleys; The core is composed of three layers of mesh rollers, which are respectively the first layer roller 13, the second layer roller 14 and the third layer roller 15 from the inside to the outside. The three layers of rollers are fixed by brackets. The mouth of the first layer roller 13 Connect the feed port 3, the end of the second layer of drum 14 is provided with a dust collection port 6, the dust collection port 6 is connected with the net cover type gas separator 4 and the negative pressure generator 1 installed on the frame 2 through the exhaust pipe 5 Connected, corresponding to the ends of the first layer of rollers 13, the second layer of rollers 14 and the third layer of rollers 15 are respectively provided with a first discharge port 7, a second discharge port 8 and a third discharge port 9; The sieve cylinder is inclined, and the inlet end is higher than the outlet end.

Start the motor 11, drive the roller 10 to rotate by the belt pulley, and drive the third layer of drum 15 to rotate, because the first layer of drum 13, the second layer of drum 14 and the third layer of drum 15 are connected as one by the bracket, so the first layer of drum 13, The second layer of drums 14 and the third layer of drums 15 rotate synchronously. After the wheat enters from the feed port 3, it first arrives at the first layer of drums 13. Grass and stalks act as a filter, and these impurities are removed through the first feeding port 7, and wheat and smaller impurities fall into the second layer of drum 14, and wheat drops the smaller impurities into the second layer of drum 14 on this layer. In the three-layer drum 15, at the outlet of the second-layer drum 14, the dust collection port 6 generates negative pressure through the negative pressure generator 1, and the dust and straw are sucked away through the air suction pipe 5, and then passed through the mesh-type gas-material separator 4 Leave the dust and straw in the separation mesh bag, the smaller sand particles fall into the third layer of drum 15 through the mesh, and the wheat spills out through the second feeding port 8, and falls into the smaller sand in the third layer of drum 15. Grain of sand spills out through the 3rd feed opening 8, and the whole cleanup work is finished cleanly and swiftly like this. In particular, the cleaning work for experimental wheat varieties is particularly concise and clear, easy to clean, and not easy to mix.
