Description

Technical Field

[0001] This utility model relates to the field of eccentric discharge technology of silos, specifically a chute feeding device for eccentric discharge of silos. Background Technology

[0002] Currently, in the field of eccentric discharge technology for silos, chutes, as key components for material conveying, often suffer from uneven material distribution due to eccentric discharge, leading to problems such as poor flow or material blockage.

[0003] Traditional chutes typically employ fixed structures or simple mechanical feeding devices, which suffer from the following drawbacks: frequent material blockage: during eccentric discharge, material tends to accumulate locally within the chute, especially when the material is highly viscous or moist. Existing feeding devices struggle to effectively disperse the material, leading to decreased production efficiency; complex structure and difficult maintenance: existing feeding devices often employ an integrated design, making disassembly and assembly inconvenient. Furthermore, the fixed installation positions of the motor and transmission components necessitate complete disassembly for maintenance or component replacement, resulting in time-consuming and labor-intensive processes; high feeding resistance: traditional feeding plates lack optimized design, resulting in significant material flow resistance. Long-term operation can easily lead to motor overload or component wear, affecting the device's lifespan; insufficient sealing: unused mounting holes or connection points lack effective sealing, easily causing material leakage and contaminating the working environment.

[0004] Based on the above problems, we propose a chute feeding device for eccentric discharge from a silo to solve these problems. Utility Model Content

[0005] In view of the problems existing in the prior art, this utility model discloses a chute feeding device for eccentric material discharge from a silo.

The outer sidewall of the bearing 8 is evenly provided with external tooth grooves. The bearing 8 is fitted with a feeding plate assembly 10 through a mounting component 9. The connecting disc 6 is inserted and fastened through the grooves 2 opened in the inner sidewall of the chute 1. Simultaneously, the pin 7 on the side wall of the connecting disc 6 is inserted into the insertion hole 4 inside the groove 2 to complete the installation and fixation of the connecting disc 6. Then, the bearing 8 is inserted through the through hole 3 in the middle of the groove 2 into the through hole 3 in the middle of the connecting disc 6 and extends into the interior of the chute 1. Then, the motor mounting bracket 12 is inserted into the interior of the mounting bracket fixing groove 5 and fixed. Then, the geared motor 13 is fixedly installed on the surface of the motor mounting bracket 12 by fixing bolts 11, and the output shaft of the geared motor 13 is engaged and fixedly installed with the bearing 8. Then, the external tooth groove on the surface of the bearing 8 is engaged with the mounting component 9 for installation. Thus, the output shaft of the geared motor 13 drives the mounting component 9 to rotate through the bearing 8. At the same time, the material feeding plate assembly 10 installed with the mounting component 9 can make the material feeding plate assembly 10 rotate synchronously with the mounting component 9 to complete the feeding of materials in the chute 1, thereby eliminating the phenomenon of poor flow in the chute 1 and solving the problem of frequent material blockage in the inclined discharge chute 1.

[0026] As a preferred embodiment of this utility model, the mounting assembly 9 includes a central block 15.

[0030] The working principle of this utility model is as follows: The connecting disc 6 is inserted and fastened into the groove 2 on the inner sidewall of the chute 1. Simultaneously, the pin 7 on the sidewall of the connecting disc 6 engages with the insertion hole 4 inside the groove 2 for insertion, thus completing the installation and fixation of the connecting disc 6. Then, the bearing 8 passes through the through hole 3 in the middle of the groove 2 and is inserted into the through hole 3 in the middle of the connecting disc 6, extending into the interior of the chute 1.
