Description

Technical Field

[0001] This utility model relates to the field of cotton hulling technology, and in particular to a wind-pressure cotton hulling machine for removing impurities. Background Technology

[0002] A cotton huller is an agricultural machine used to process cotton. It is mainly used to separate cotton fibers from cotton bolls. It can improve the efficiency of cotton processing, reduce manual labor, and increase production benefits. The working principle of a cotton huller is usually to separate the outer shell of the cotton boll from the cotton inside by mechanical force.

[0003] However, in actual use, some existing cotton hulling machines suffer from dust inside the cotton plants, which are usually grown outdoors. Even after hulling, the dust remains inside the cotton, resulting in a less than ideal processing effect and affecting the quality of the cotton. Therefore, it is necessary to solve these problems. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a wind-pressure cotton hulling and deworming machine.

Two side plates are fixedly connected inside the outer shell, both inclined, and a guide roller is rotatably connected between them. Guide plates are fixedly connected to the top of each side plate, and are respectively positioned on top of the guide rollers. A rotating mechanism for the guide rollers is provided on the surface of the outer shell. An arc-shaped screen plate is horizontally fixed inside the outer shell, with its top end fixedly connected to the bottom of the two side plates. A conveying mechanism is located inside the arc-shaped screen plate, and a dust-collecting mechanism is located inside the outer shell. The two guide rollers guide the dehulled cotton inside the feed inlet and simultaneously drive the conveying rollers to rotate. Under the action of the threaded strip, the cotton is conveyed through the surface of the arc-shaped screen plate. Combined with the dust collector, this facilitates the removal of dust and impurities from the cotton.

[0007] Preferably, the rotating mechanism includes a geared disc, with a fixed shaft sleeved at the center of each of the two guide rollers. The two ends of the fixed shafts are respectively rotatably sleeved on opposite sides inside the outer casing. There are two geared discs that mesh with each other. Each geared disc is fixedly connected to one end of the two fixed shafts. A support plate is fixedly connected to one side of the outer casing surface.

[0008] Furthermore, the conveying mechanism includes a threaded strip, and a conveying roller is rotatably connected inside the outer casing. The conveying roller is disposed on the surface of an arc-shaped screen plate, and the surface of the arc-shaped screen plate is provided with multiple screen holes. The threaded strip is fixedly connected to the outer surface of the conveying roller. A discharge port is opened on the side of the outer casing away from the support plate, and the discharge port is disposed at one end of the arc-shaped screen plate. A rotating shaft is sleeved at the center inside the conveying roller. Two rotating shafts are respectively rotatably sleeved on opposite sides inside the outer casing.

[0010] The beneficial effects of this utility model are as follows:

[0011] 1. The drive motor drives one of the gear discs to rotate. With the cooperation of the two gear discs, the two guide rollers will rotate simultaneously, which will convey the cotton inside the feed inlet downwards. At the same time, with the connection of the synchronous belt and synchronous pulley, the conveyor roller will rotate simultaneously.
