[0002] The agricultural packaging scale consists of a weighing unit, a bag sewing and conveying device, a pneumatic system, a dust removal system and a quantitative packaging control instrument. A dust removal device is required to clean the dust and impurities in the material before leaving the warehouse.

[0003] A Chinese patent with publication number CN210391785U discloses a dust removal device for a grain baler, comprising a dust box housing, a dust box housing provided with a movable device, a dust box housing with a feed inlet fixedly connected to a funnel, a dust box housing with a discharge outlet fixedly connected to a discharge carrier, a dust box housing fixedly connected to a transport device, a first filter screen slidably connected to the dust box housing, a second filter screen slidably connected to the middle portion of the dust box housing, an air outlet at the top back of the dust box housing, an air filter device provided on the back of the dust box housing, and a door panel connected to one side of the dust box housing. The design of the first filter screen of the utility model is that the holes on the first filter screen will take into account particles larger than the grain, allowing grain or particles smaller than the grain to leak out, while the second filter screen is used to filter out the grain separately, filtering out particles smaller than the grain. The two filter screens can be used in combination to remove large and small particles in the grain.

[0004] The dust removal device on the existing agricultural baling scale removes dust from the material through a filter during the dust removal process of the baled material, but cannot completely remove the dust attached to the material, resulting in poor dust removal effect; therefore, to address the above problem, an agricultural baling scale dust removal device is proposed.

When working, the dust removal device on the existing agricultural packaging scale removes dust from the packaged materials through the filter screen, but cannot completely remove the dust attached to the materials, resulting in poor dust removal effect. The weighing control system in the control panel 20 controls the first solenoid valve 6 to open, the discharge pipe 5 is opened, and the granular materials in the storage bin 4 are discharged from the discharge pipe 5. The material pipe 5 falls into the dust suction pipe 7, and then falls from the dust suction pipe 7 into the weighing hopper 21.

When the material weight reaches the set value, the first solenoid valve 6 is closed, the discharge pipe 5 is closed, and the dynamic weighing process is completed. After that, the system sends a control signal, the second solenoid valve 22 is opened, and the material enters the packaging bag from the weighing bucket 21. After the material is discharged, the second solenoid valve 22 of the weighing bucket 21 is automatically closed, so that the weighing bucket 21 is closed. The weighing and packaging of the materials is realized; in the process of the granular material in the storage bin 4 falling from the discharge pipe 5 to the dust suction pipe 7, and then falling from the dust suction pipe 7 into the weighing bucket 21, the motor 13 is operated to drive the rotor 14 to rotate, and the rotor 14 drives the fan blades 15 to rotate at high speed, so that the air in the exhaust box 12, the dust suction box 11, the duct 10 and the cavity 8 is instantly discharged from the exhaust slot 19. There is a pressure difference between the exhaust box 12 and the outside world. Under the action of the pressure difference, the outside air is sucked into the cavity 8 from the dust suction hole 9. In the process of the granular material passing through the dust suction pipe 7, the dust attached to the granular material is sucked into the cavity 8 together with the air, and then the dust and air enter the dust collecting box 16 in the dust collecting box 11 from the duct 10.
