Description

Technical Field

[0001] This utility model relates to the field of grain processing technology, specifically a grain dust removal device. Background Technology

[0002] The term "grains" encompasses a broad range, including rice, wheat, millet, soybeans, and other miscellaneous grains. Grains, including rice, wheat, millet, and soybeans, are primarily plant seeds and fruits; they are a traditional staple food for many Asians; grains absorb a lot of dust particles during the drying process, which need to be removed before further processing.

[0003] Chinese invention patent CN109626011B, published on May 25, 2021, discloses a grain dust removal device, including a support frame composed of two main support rods and multiple connecting rods. Each end of one main support rod has a roller, and a height adjustment mechanism is provided between the rollers and the main support rods. A grain conveying mechanism and a grain dust removal mechanism are located between the two main support rods. A horizontally placed cylindrical roller is rotatably connected to the opening of the trough plate. A large pulley is fixed to the shaft of the cylindrical roller, and the large pulley is connected to a small pulley via a belt. Half of the cylindrical roller is placed inside a housing, and several evenly distributed receiving plates are fixed to the cylindrical roller. A debris box is located at the bottom of the electrostatic plate. This device eliminates the need for power supply by pulling wires, completing the dust removal process during grain turning, making it convenient for farmers to use, saving energy, simplifying the drying and dust removal process, and promoting agricultural development.

[0004] However, the aforementioned publicly available solutions have the following shortcomings: Existing grain dust removal devices all use the method of exposing the dust to the air and using the flowing wind to carry away the dust. However, this method exposes the dust directly to the air and moves with the wind, which will pollute other objects in the environment. At the same time, people located downwind will be contaminated by the dust. Utility Model Content

[0005] The purpose of this invention is to solve the technical problem that existing grain dust removal devices all use the method of exposing the grain to the air and using the flow of wind to carry away the dust. However, this method exposes the dust directly to the air and it moves with the wind, which will pollute other objects in the environment. At the same time, people located downwind will be contaminated by the dust. This invention provides a grain dust removal device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution;

[0007] The present invention discloses a grain dust removal device, comprising a rolling tube; a plurality of dust removal holes are formed through the rolling tube; a spiral auger is fixedly connected to the inner surface of the rolling tube; symmetrically fitted lifting rings are fitted onto the rolling tube; the lifting rings are provided with toothed grooves; a drive wheel is meshed and driven onto the toothed grooves; a motor is fixedly connected to the drive wheel; a fixed tube is fitted onto the lifting rings; a side tube is connected and fixedly connected to the fixed tube; and an air dust removal unit is provided inside the side tube.

[0008] Furthermore, the air dust removal unit includes a filter plate inserted into a side tube; a fan is fixed to the end of the side tube.

[0009] Furthermore, a fixing seat is fixedly connected to the fixing tube; a supporting base is fixedly connected to the lower surface of the fixing seat.

[0010] The grain dust removal device provided by this utility model has the following beneficial effects:

[0011] 1. This utility model uses a motor to drive a drive wheel, which in turn rotates the lifting ring and the rolling tube. Grains are poured in from one end of the rolling tube and gradually move forward inside the auger as the rolling tube rotates. During this process, the grains fall through the dust removal holes to remove dust. The air dust removal unit generates an air pressure difference to carry away the fallen dust, filter it, and discharge it into the air. This prevents the dust from spreading into the air and polluting other objects and the respiratory health of the operators.

[0012] 2. This utility model generates negative air pressure by powering on the fan, thereby expelling the air inside the rolling tube through the side tube. Along the air's path, the air is filtered by the filter plate to remove dust, thus ensuring that the air is released into the atmosphere without polluting the air environment or the respiratory health of the user.

[0019] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] It should be noted that all directional indications (such as up-down-left-right-forward-backward...) in the embodiments of this utility model are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly. The connection can be a direct connection or an indirect connection.

[0021] Please see Figure 1-3 As shown, a grain dust removal device includes a rolling tube 1; multiple dust removal holes 2 are opened through the rolling tube 1; a spiral auger 3 is fixedly connected to the inner surface of the rolling tube 1; symmetrically fitted lifting rings 14 are fitted onto the rolling tube 1; the lifting rings 14 have toothed grooves 4; a drive wheel 5 is meshed and driven onto the toothed grooves 4; a motor 6 is fixedly connected to the drive wheel 5; a fixed pipe 7 is fitted onto the lifting rings 14; a side pipe 8 is connected and fixedly connected to the fixed pipe 7; an air dust removal unit is provided inside the side pipe 8. The motor 6 drives the drive wheel 5 when it is powered on, and the drive wheel 5 drives the lifting rings 14 and the rolling tube 1 to rotate. Grain is poured into the rolling tube 1 from one end, and then gradually moves forward in the spiral auger 3 under the rotation of the rolling tube 1. During the forward movement, the grain falls through the dust removal holes 2 to achieve dust removal. Then, the air dust removal unit generates an air pressure difference to carry away the falling dust, filter it, and discharge it into the air, so as not to spread the dust into the air and pollute other objects and the respiratory health of the operators.

[0022] The air dust removal unit includes a filter plate 9 inserted into the side tube 8; a fan 10 is fixed to the end of the side tube 8. When the fan 10 is powered on, it generates negative air pressure, thereby discharging the air in the rolling tube 1 through the side tube 8. Along the path of the air movement, the filter plate 9 filters the dust, so that the air is discharged into the atmosphere without polluting the air environment or the respiratory health of the users.

[0023] A fixed base 12 is fixedly connected to the fixed tube 7; a support base 13 is fixedly connected to the lower surface of the fixed base 12, and the entire structure is supported by the support base 13, so that it can be easily moved and placed on a flat surface for use.

[0024] A feed hood 11 is fitted onto the rolling tube 1, which allows bagged grains or grains transported by a conveyor belt to continuously enter the rolling tube 1, thus continuously removing dust from the grains.

[0025] Multiple casters (existing technology, not shown in the figure) are fixed to the lower surface of the support base 13, making it more convenient to move on the plane and move from indoor to outdoor locations, thereby reducing pollution to the indoor environment.

[0026] The motor 6 is fixed to the outer surface of the fixed tube 7, so that the vibration of the motor 6 can be transmitted to the fixed tube 7, the side tube 8 and the filter plate 9, thereby shaking off the dust accumulated on the filter plate 9, so that the dust will not completely surround the filter plate 9, and thus the dust can be filtered for a long time.
