[0019] Embodiment:

[0020] Please refer to Figure 1- Figure 6 , the present utility model provides a technical solution: a spiral blade cleaning device, comprising: a conveyor housing 1; a motor 2, the outer wall of the motor 2 is fixedly connected to the outer wall of the conveyor housing 1 through a frame; a spiral blade body 4, the outer wall of the spiral blade body 4 is fixedly connected to the output end of the motor 2; a cleaning assembly 3, the outer wall of the cleaning assembly 3 is fixedly connected to the outer wall of the conveyor housing 1; the cleaning assembly 3 includes a main gas pipeline 31, there are two groups of the main gas pipelines 31, the inner wall of the conveyor housing 1 is fixedly connected with a mounting plate 34 through bolts, the outer wall of the mounting plate 34 is fixedly connected with a high-pressure air knife 35, and the high-pressure air knife 35 is fixed on the conveyor housing 1 through the mounting plate 34. A connecting joint 32 is fixedly connected to the outer wall of the main gas pipeline 31, and the connecting joints 32 are linearly arranged along the central axis of the main gas pipeline 31.

[0021] One end of the connecting joint 32 away from the main gas pipeline 31 is fixedly connected with an air vent hose 33, the air vent hose 33 diverts the gas into the high-pressure air knife 35, and the air vent hoses 33 are linearly arranged along the central axis of the main gas pipeline 31. One end of the air vent hose 33 away from the connecting joint 32 is fixedly connected to the outer wall of the high-pressure air knife 35.

[0022] Air holes 36 are formed in the wall of the high-pressure air knife 35, and the air holes 36 are linearly arranged along the outer wall of the high-pressure air knife 35. The outer wall of the high-pressure air knife 35 is fixedly connected to the inner wall of the conveyor housing 1. The high-pressure gas ejected through the air holes 36 is blown onto the spiral blade body 4, so as to remove the attachments on the spiral blade body 4. This device is installed on the conveyor housing 1 and can be positioned according to the conveyor model; when the material is flowing, by controlling the air supply volume, it is blown onto the blade, so as to separate the blade from the attachments; when the material is being conveyed, the high-pressure air knife 35 is in a trimming state, and when the material stops being conveyed, the high-pressure air knife 35 works; the high-pressure air knife 35 sprays in a row shape, combined with the rotation of the spiral blade body 4, to achieve the effect of cleaning the entire spiral blade body 4 without changing the original characteristics of the material.

[0023] Working principle:

[0024] During use, before using the cleaning device, the cleaning assembly 3 needs to be installed on the conveyor housing 1. After fixing the cleaning assembly 3 on the conveyor housing 1 with bolts, an external air pipe can be connected to the two groups of main gas pipelines 31, so that high-pressure gas can enter the cleaning assembly 3.

[0025] When installing the cleaning component 3, it is only necessary to place the mounting plate 34 on the high-pressure air knife 35 on the conveyor casing 1, and use bolts to pass through the mounting plate 34 and screw it into the conveyor casing 1 to fix the high-pressure air knife 35 in the conveyor casing 1. Then, the high-pressure air knife 35 is connected to the connecting joint 32 on the gas main pipeline 31 through the ventilation hose 33, so that the airflow in the gas main pipeline 31 can be diverted to the high-pressure air knife 35.

[0026] When high-pressure gas enters the gas main pipeline 31, the high-pressure gas will enter the high-pressure air knife 35 under the diversion of the ventilation hose 33, and be ejected from the air holes 36 on the high-pressure air knife 35, converting the high-pressure gas into a high-speed, uniform, and thin-sheet airflow, which peels off and blows off the attachments on the spiral blade body 4. The attachments are carried away by the airflow and fall into the collector or are discharged to the outside, and the spiral blade body 4 can be driven to rotate by the motor 2, further increasing the cleaning efficiency of the cleaning device.

[0027] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. Structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to conventional means in the field unless otherwise specified and limited.
