Description

Technical Field

[0001] The utility model relates to the technical field of dust removal equipment for flour mills, in particular to an environmentally friendly dust extraction device for a mobile flour mill. Background Art

[0002] Flour is a powder made from wheat and is a traditional staple food in China. As the name suggests, a flour mill processes flour. Usually, a city contains several flour mills. Like most factories, flour mills often have a lot of dust because of their large factory area. In addition, the flour mill itself has a lot of dust, which will fall on the ground more than ordinary factories. However, flour mills are different from other factories. They cannot encounter open flames and static electricity, otherwise there will be explosions, so a special dust extraction device is needed to clean the ground.

[0003] Chinese patent CN209269540U discloses a mobile environmentally friendly dust extraction vehicle for flour mills, including a body, a dust extraction hood is fixedly installed on the left side of the body through a fixed block, the top of the dust extraction hood is connected to a dust extraction pipe, and the end of the dust extraction pipe away from the dust extraction hood passes through and extends to the interior of the body, an exhaust fan is fixedly installed on the dust extraction pipe, a water tank is fixedly installed on the inner bottom wall of the body, a motor, two telescopic limit rods and two springs are fixedly installed on the inner top wall of the body, and a fixed plate is fixedly installed between the bottom ends of the two springs, and two triangular plates are fixedly installed on the top of the fixed plate. The utility model solves the problems of the existing mobile dust extraction device, poor dust extraction effect, incomplete suction, and ineffective collection of dust after suction, and achieves the effects of high working efficiency, good dust suction effect, and dust after suction does not overflow and is easy to collect. However, there are still defects that need to be improved:

[0004] 1. The dust hood of the utility model is fixedly connected to the vehicle body. However, in reality, when the dust hood is too high from the ground, the dust extraction effect of the target area will be reduced, and residual dust will remain, which requires multiple cleaning; if the dust hood is set to be lower from the ground, dust will stick to the dust hood in dusty places, and too low a distance will also cause wear between the dust hood and the ground.

[0005] 2. The dust extraction pipe of the utility model extends into the water in the water tank. Although this effect can prevent dust from flying around in the car body, when the vacuum cleaner is turned on, air will be blown into the water tank. If the dust extraction pipe extends into the water tank, the water in the water tank will be blown up, and eventually the water in the water tank will be blown into the car body. At the same time, when the vacuum cleaner is turned off, due to the change in air pressure, the water in the water tank will flow back into the vacuum cleaner from the dust extraction pipe, which may cause the vacuum cleaner to be scrapped.

It is worth noting that the threaded block 1 506 and the threaded block 2 507 are both slidably connected to the base 1, and then a motor 1 501 is arranged on the side of the baffle 2 3 away from the threaded block 2 507. The motor 1 50 1 is fixedly connected to the base 1 by providing a motor seat 1 502, and a smooth rod 503 is fixedly connected to the output shaft of the motor 1 501. It is worth noting that the smooth rod 503 passes through the baffle 2 3 on the side away from the motor 1 501 and is rotatably connected to the baffle 1 2. At the same time, the smooth rod 503 is respectively provided with a threaded portion 1 504 and a threaded portion 2 505 with opposite thread rotation directions. Finally, the threaded portion 1 504 is threadedly connected to the thread block 1 506, and the threaded portion 2 505 is threadedly connected to the thread block 2 507.

[0034] The technical effect achieved by the technical solution composed of the above-mentioned technical features is: when the motor 1 501 drives the smooth rod 503 to rotate together, the threaded block 1 506 and the threaded block 2 507 threadedly connected to the threaded portion 1 504 and the threaded portion 2 505 on the smooth rod 503 begin to move toward the similar side. When the threaded block 1 506 and the threaded block 2 507 move toward each other, the rotating plate 508 begins to rotate, and the height of the rotating plate 508 in the vertical direction gradually increases. Finally, the rotating plate 508 pushes the support plate 4 to increase the height. When the motor 1 501 rotates in the opposite direction, the height of the support plate 4 decreases.

At the same time, a pin shaft 804 is fixedly connected to the top of the sliding block 805, and a rotating block 803 is inserted on the pin shaft 804. Finally, a motor 801 is arranged in the middle part above the box body 6, and the motor 801 is fixedly connected to the box body 6 by a motor seat 802, and the output shaft of the motor 801 passes through the box body 6 and is connected to the rotating block 803.

[0036] The technical effect achieved by the technical scheme composed of the above-mentioned technical features is: when the motor 2 801 starts to drive the rotating block 803 to rotate, the rotating block 803 first drives the pin shaft 804 and the sliding block 805 to move together. At the same time, since the rotating block 803 follows the motor 2 801 to make a circular motion, the pin shaft 804 will continue to move up and down in the rotating block 803 while moving forward and backward. While the sliding block 805 moves on the positioning shaft 1 806, it will push the positioning shaft 1 806 to swing to both sides. When the positioning shaft 1 806 swings, the swing blocks 807 at the front and rear ends of the positioning shaft 1 806 will rotate the positioning shaft 2 808 fixedly connected to the swing block 807. When the positioning shaft 2 808 rotates, the positioning block 810 fixedly connected to the positioning shaft 2 808 will swing along with it, and finally, the rotation of the rotating block 803 will drive the positioning block 810 and the nozzle 12 to swing together.

[0037] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
