[0036] When feeding the polypropylene particles, the power supply of the electric heating pipe 3 and the conveying motor 101 is turned on, the raw materials are poured into the inside of the feeding hopper 104 and fall into the vertical pipe 2, the inside of the vertical pipe 2 is continuously heated by the electric heating pipe 3, the falling materials can be directly dried, the materials after heating enter the inside of the conveying pipe 1, the conveying motor 101 drives the spiral conveying rod 102 to rotate, the materials are conveyed upward and discharged, and in the process of rotation of the spiral conveying rod 102, the operation of the extension mechanism 5 can be directly controlled, the vertical sliding of the dredging rod 4 is linked and controlled, the materials in the inside of the vertical pipe 2 are dredged to avoid the blockage of the materials, and after the materials are discharged from the discharge port 103, the dust scattered out can be collected and stored by the dust removal mechanism 6.

[0037] Example 2

[0038] The solution in Example 1 will be further described below with reference to its specific working method.

[0039] like Figure 1 As shown, in a preferred embodiment, based on the above method, support rods are vertically provided at the four corners of the bottom of the feed hopper 104, and a top rod is provided at the bottom end of the conveying pipe 1.

[0040] The feed hopper 104 is stably supported by the support rod, while the top rod ensures the stability of the conveying pipe 1.

[0042] As the unblocking rod 4 slides up and down, the inclined rod 401 slides simultaneously, improving the unblocking effect on the raw materials.

[0043] like Figure 3 As shown, in a preferred embodiment, based on the above method, the telescopic mechanism 5 further includes a drive cavity 501, a cam 502, a pressure block 503 and a spring 504.

The pressure block 503 is provided between the top of the pressure block 503 and the top of the drive cavity 501.

[0044] During the rotation of the screw conveyor 102, the cam 502 is driven to rotate. During the rotation, the cam 502 will contact the bottom of the pressure block 503 and squeeze the pressure block 503 and the unblocking rod 4, while compressing the spring 504. After the cam 502 separates from the pressure block 503, the unblocking rod 4 is reset under the elastic force of the spring 504, thereby controlling the up and down movement of the unblocking rod 4.

[0045] like Figure 3 As shown, in a preferred embodiment, based on the above method, the end of the cam 502 is rotatably mounted with a ball bearing, and the bottom of the pressure block 503 is coated with a wear-resistant coating.

[0046] The contact between the ball bearings on the cam 502 and the pressure block 503 reduces frictional resistance, while the use of a wear-resistant coating on the bottom of the pressure block 503 reduces wear on the pressure block 503.

The collection chamber 604 is in communication with the inside of the dust collection hood 603. The filter cartridge 605 is provided inside the collection chamber 604. The negative pressure suction assembly is provided at the end of the collection chamber 604.

[0048] When removing dust from the discharged material, a negative pressure suction component is used to generate negative pressure inside the collection chamber 604, and the dust when the material is discharged is collected inside the collection chamber 604 through the dust collection hood 603, and then the dust is filtered and stored by the filter cartridge 605.

[0049] like Figure 4 As shown, in a preferred embodiment, based on the above method, the negative pressure suction assembly further includes a housing 601 and a fan blade 602. The housing 601 is fixed to the end of the conveying pipe 1, the end of the spiral conveying rod 102 extends into the interior of the housing 601, and the fan blade 602 is installed inside the spiral conveying rod 102. The air inlet on the housing 601 is connected to the end of the collection chamber 604.

[0050] When materials are conveyed quickly, the conveyor motor 101 drives the screw conveyor 102 to rotate rapidly. The screw conveyor 102 drives the fan blade 602 to rotate inside the housing 601, generating negative pressure inside the housing 601. The housing 601 is connected to the inside of the collection bin 604 through a pipe, allowing air to enter from inside the collection bin 604.

[0051] Example 3

[0052] The solutions in Embodiments 1 and 2 will be further described below with reference to their specific working methods.
