[0001] The present application relates to the technical field of feeding devices, and in particular to a dust removal device for grain processing. Background Art
[0002] In the grain processing industry, the application of automatic feeding devices has become more and more widespread. These devices usually include suction, lifting and conveying, with a high degree of automation, which effectively improves production efficiency. However, the existing automatic feeding devices have obvious deficiencies in dust filtration. A large amount of dust will be generated during the grain processing process. This dust will not only pollute the environment, but also harm the health of operators; therefore, we propose a dust removal device for grain processing to solve this problem.

[0007] Preferably, the two inner scissor rods are rotatably connected to the outer side of the limit block, and the outer sides of the two inner scissor rods are movably connected to the inner side of the first connection group through a second pulley.
[0008] Preferably, two cylinders are hinged on the outer side of the sliding block, and one end of the two cylinders away from the sliding block is hinged on the outer side of the limiting block.

[0013] 1. Through the operation of the suction fan, negative pressure is formed inside the second feed pipe, and the dust and debris in the grain are sucked into the inner side of the dust box through the connecting pipe for collection.

[0020] The following is combined with Figure 1-4 This application is described in further detail.
[0021] The present application embodiment discloses a dust removal device for grain processing. Figure 1-4 A dust removal device for grain processing comprises a device body 1, a feed pipe 2 is arranged at the bottom of the device body 1, the device body 1 is communicated with the inner side of the feed pipe 2, a second feed pipe 4 is fixedly connected to the top of the device body 1, and a lifting mechanism is arranged on the inner side of the second feed pipe 4; the lifting mechanism comprises a first connection group 8, the first connection group 8 is fixedly connected to the top of the device body 1, two outer scissor rods 10 are arranged on the first connection group 8, the outer sides of the two outer scissor rods 10 are hinged with inner scissor rods 11, the two outer scissor rods 10 are rotatably connected with the same slider 12, a second connection group 9 is arranged above the first connection group 8, the slider 12 is movably connected to the inner side of the second connection group 9 through two first pulleys 13, and the inner side of the second connection group 9 is rotatably connected to a limited position block 15.
[0022] Reference Figure 1-4 , the two inner scissor rods 11 are rotatably connected to the outside of the limit block 15, the outsides of the two inner scissor rods 11 are movably connected to the inside of the first connection group 8 through the second pulley, the outside of the slider 12 is hinged with two cylinders 14, one end of the two cylinders 14 away from the slider 12 is hinged to the outside of the limit block 15, the top of the second connection group 9 is fixedly connected with the first feed pipe 3, and the first feed pipe 3 is slidably connected to the inside of the second feed pipe 4; by starting the two cylinders 14, the two cylinders 14 shrink inwardly, because the ends of the two cylinders 14 are hinged with the same slider 12, the slider 12 is movably connected to The inner side of the second connection group 9, therefore, the contraction of the two cylinders 14 can reduce the distance between the limit block 15 and the slider 12, thereby causing the slider 12 to contract along the direction of the second connection group 9, thereby reducing the diameter distance between the first connection group 8 and the second connection group 9. Because the first connection group 8 is fixedly connected to the top of the device body 1, and the top of the second connection group 9 is fixedly connected to the bottom of the first feed pipe 3, the contraction of the two cylinders 14 can move the first feed pipe 3 upward, thereby expanding the storage space between the first feed pipe 3 and the second feed pipe 4, making it convenient for the staff to fill more stuffing into the hopper.
[0023] Reference Figure 1-4 A dust box 5 is fixedly connected to the top of the device body 1, and the dust box 5 is connected to the second feeding pipe 4 through a connecting pipe. A first filter is arranged between the dust box 5 and the second feeding pipe 4, and a drawer 6 is slidably connected to the inner side of the dust box 5.
[0024] Reference Figure 1-4 , a suction fan 7 is arranged on the outside of the dust collecting box 5, a second filter screen is arranged between the dust collecting box 5 and the suction fan 7, and the suction fan 7 is fixedly connected to the top of the device body 1; by starting the suction fan 7, when the suction fan 7 is working, a negative pressure is formed inside the second feeding pipe 4, and the dust and debris in the grain are sucked into the inner side of the dust collecting box 5 through the connecting pipe for collection. Since a first filter screen is arranged between the second feeding pipe 4 and the dust collecting box 5, and the diameter of the first filter screen is smaller than the diameter of the grain, the grain can be prevented from entering the inner side of the dust collecting box 5, and because a second filter screen is arranged between the dust collecting box 5 and the suction fan 7, the diameter of the second filter screen is smaller than the diameter of the dust and debris, dust and debris can be prevented from entering the inner side of the suction fan 7, thereby causing damage to the suction fan 7. Through the setting of the vacuum cleaner, the dust generated during the transportation of grain is effectively reduced, and the working environment is improved.
[0025] The implementation principle of the dust removal device for grain processing in the embodiment of the present application is as follows: when the staff uses the device to discharge materials, the staff can first start the suction fan 7. When the suction fan 7 is working, a negative pressure is formed inside the second feeding pipe 4, and the dust and debris in the grain are sucked into the inner side of the dust collecting box 5 through the connecting pipe for collection. Since a first filter is arranged between the second feeding pipe 4 and the dust collecting box 5, and the diameter of the first filter is smaller than the diameter of the grain, the grain can be prevented from entering the inner side of the dust collecting box 5. Since a second filter is arranged between the dust collecting box 5 and the suction fan 7, and the diameter of the second filter is smaller than the diameter of the dust and debris, the dust and debris can be prevented from entering the inner side of the suction fan 7, thereby causing damage to the suction fan 7. Through the setting of the vacuum cleaner, the dust generated during the transportation of grain is effectively reduced, the working environment is improved, and the health of the operators is protected.
[0026] When it is necessary to expand the internal storage space of the feed pipe, the staff can start the two cylinders 14, and the two cylinders 14 will retract inward. Since the ends of the two cylinders 14 are hinged with the same slider 12, and the slider 12 is movably connected to the inner side of the second connection group 9 through two first pulleys 13, the contraction of the two cylinders 14 can reduce the distance between the limit block 15 and the slider 12, so that the slider 12 can be contracted along the direction of the second connection group 9, thereby reducing the diameter distance between the first connection group 8 and the second connection group 9. Because the first connection group 8 is fixedly connected to the top of the device body 1, and the top of the second connection group 9 is fixedly connected to the bottom of the first feed pipe 3, the contraction of the two cylinders 14 can move the first feed pipe 3 upward, thereby expanding the storage space between the first feed pipe 3 and the second feed pipe 4, making it convenient for the staff to fill more stuffing into the hopper.
