Description

Technical Field

[0001] The utility model relates to the technical field of screening machines, in particular to a dust removal mechanism for screening machines. Background Art

[0002] Seeds are reproductive bodies unique to gymnosperms and angiosperms. They are formed by ovules through pollination and fertilization. Seeds are generally composed of three parts: seed coat, embryo and endosperm. Some mature seeds of plants only have seed coat and embryo. Some seeds need to be dried, screened and cleaned before planting, storage or consumption, which requires the use of seed screening machines.

[0003] However, in the process of screening seeds, the existing screening machine will screen the seeds according to their size. After the screening is completed, dust will remain inside the seeds and the dust cannot be cleaned well. Utility Model Content

[0007] A rotating shaft, a rotating plate is disposed on the surface of the rotating shaft, an extending block is disposed on the surface of the rotating plate, an extending plate is fixed on the surface of the extending block, and a baffle plate is disposed on the surface of the extending plate; and

[0008] The limiting strip is arranged at the end of the baffle plate.

[0009] Preferably, the vibrating screen is located between the support rods, and the vibrating screen is rotated by a vibrating assembly, an inclined plate is fixed to the bottom of the vibrating screen, the inclined plate vibrates along with the vibrating screen, and a material guide trough is fixed to the end of the vibrating screen.

[0010] Preferably, a fan is fixed at the bottom of the vibration screen, and the fan is fixed between two groups of support rods. An arc plate is fixed at the end of the vibration screen, and a through groove is formed on the surface of the arc plate.

[0011] Preferably, the rotating shaft can rotate, and the rotating plate rotates along with the rotating shaft. An extension block is fixed on the surface of the rotating plate, and a sponge is arranged on the surface of the extension block.

[0012] Preferably, an extension plate is fixed on the surface of the extension block, a baffle plate is plugged into the surface of the extension plate, the baffle plate can move inside the extension plate, and a limiting strip is fixed to the end of the baffle plate.

[0013] Preferably, the extension block is held in the through slot, and a spring is provided inside the extension plate, one end of the spring is connected to the inside of the extension plate, and the other end is connected to the end of the baffle plate.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] The seeds proposed in the utility model are located on the surface of the vibration screen, and the vibration screen is located between the support rods. The vibration screen can vibrate between the support rods through the vibration component. After the vibration screen vibrates, the seeds are screened, and some seeds fall into the guide trough, and the others pass through the vibration screen and fall onto the surface of the inclined plate. In the process of the seeds falling, the fan blows air so that the air blows on the surface of the falling seeds, so that the dust on the surface of the seeds is blown to the surface of the extension block. The extension block is wet, and the dust adheres to the surface of the extension block. The arc plate prevents the seeds from being blown off, and the rotating shaft is rotated so that the rotating plate rotates with the rotating shaft.
