AI Technical Summary
In existing pellet mills, larger particles are stored after screening, while smaller particles overflow, and larger particles cannot enter the pelleting chamber, resulting in powder overflow problems.
A large-bellied discharge chute for a pellet mill was designed. By increasing the width of the discharge chute and adopting structures such as widened double doors, flange sealing gaskets, and operating lever shafts, the effective discharge of pellets is ensured.
This solved the problem of powder overflow, ensuring that materials that do not meet the requirements do not enter the granulation chamber, thus improving the efficiency and effectiveness of unloading.

[0006] Preferably, a cover plate 8 is connected to the main frame 1 of the unloading chute via a hinge. The cover plate 8 is located at the upper end of the widened double door 3 and is connected to the widened double door 3 via a buckle device.
[0007] Preferably, an operating lever shaft 9 is provided in the middle section of the main frame 1 of the unloading trough, and two operating lever shafts 9 are arranged parallel to each other vertically.
[0008] Preferably, both ends of the operating lever shaft 9 are fitted with shaft rings 10, and the ends of the two operating lever shafts 9 that are far apart from each other are fitted with shaft sleeves 11.
[0009] Preferably, the main frame 1 of the unloading trough is provided with air support mounting plates 12 symmetrically on both sides, and the upper end of the air support mounting plate 12 is provided with an air support 13, and the exposed end of the air support 13 is connected to a shaft clamp 14 for connecting the bushing 11.
[0010] Preferably, a discharge chute door 15 is provided on the side of the discharge chute main frame 1 away from the discharge chute main frame 1.
[0011] Preferably, the two side walls of the main frame 1 of the unloading trough are symmetrically provided with sealing gaskets 16 for connecting the door frame.
[0012] Beneficial effects of the invention:
[0013] Increase the width of the unloading chute to solve the problem of powder overflow and ensure that materials that do not meet the requirements do not enter the granulation chamber. Attached Figure Description
