Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of plate feeders, specifically relating to a leak-proof feeder guardrail. Background Technology
[0002] In industries such as mining, metallurgy, and building materials, plate feeders are widely used as key continuous conveying equipment for transporting lumpy and granular bulk materials, serving as a crucial link in production lines connecting crushing and screening processes. However, in actual operation, material leakage remains a persistent problem hindering enterprise production. During the conveying process, due to material impact, vibration, and the gap between the conveyor belt and the frame, some material leaks out from the edge or bottom of the conveyor belt. This leakage not only pollutes the production environment and increases cleaning workload and labor costs, but also accumulates on moving parts such as idlers and chains, causing abnormal wear, jamming, or even malfunctions and shutdowns, severely impacting equipment lifespan and the continuous operating efficiency of the production line. Existing technologies often use side rails on both sides of the conveyor belt to prevent leakage, but traditional side rails have obvious drawbacks. They are mostly fixed structures, and their height and angle cannot be flexibly adjusted according to the type of material, particle size, and conveying volume. When there is a large amount of material or the particles are large, leakage will still occur, and it will also cause inconvenience to equipment maintenance and repair. Meanwhile, traditional side panels and frames are mostly fixed by welding or a single bolt, making installation and disassembly cumbersome. Long-term use can easily lead to loosening of the connection due to vibration, exacerbating material leakage. In addition, the simple structural design makes them prone to deformation and damage from material impact, resulting in a short service life and frequent replacements, significantly increasing the company's production costs.

[0013] like Figure 1-2 As shown, the anti-leakage guardrail of the plate feeder includes a clamping structure and a guardrail. The clamping structure includes a front clamping plate 1 and a rear clamping plate 2. The upper and lower ends of the front clamping plate 1 and the upper and lower ends of the rear clamping plate 2 are respectively provided with several bolt holes 3. The front clamping plate 1 and the rear clamping plate 2 are connected by several bolts 4 passing through the bolt holes 3. The guardrail includes a fixed guardrail 5 and a movable guardrail 6. The lower end of the fixed guardrail 5 is located between the front clamping plate 1 and the rear clamping plate 2. The lower end of the fixed guardrail 5 is provided with several mounting holes 15 for the bolts 4 to pass through. The lower end of the movable guardrail 6 is hinged to the upper end of the fixed guardrail 5. A support plate 7 is fixedly connected to the back of the upper end of the fixed guardrail 5. The support plate 7 is provided with threaded holes 8. A limit screw 9 is connected to the threaded holes 8. A torsion spring 10 is provided between the movable guardrail 6 and the fixed guardrail 5. The movable guardrail 6 is controlled by the torsion spring 10 to press against the limit screw 9. The front clamping plate 1 and the rear clamping plate 2 are used to clamp the feeder onto the trough plate 16 on the conveyor belt, or onto the side panels of the feeder, or other locations where material leakage needs to be prevented. The entire feeder is secured to the feeder using bolts 4 that pass through the lower ends of the front clamping plate 1 and the rear clamping plate 2. The angle between the movable feeder plate 6 and the fixed feeder plate 5 is adjusted by using the limit screw 9 to hold the movable feeder plate 6 in place.
[0014] Furthermore, the upper end of the fixed guardrail 5 is provided with several movable slots 11, and the lower end of the movable guardrail 6 is provided with several connecting parts 12 that are respectively inserted into the movable slots 11.

A torsion spring 10 is sleeved on the rotating shaft 13, with one end of the torsion spring 10 connected to the rotating shaft 13 and the other end connected to the fixed guardrail 5.
[0015] Furthermore, rubber pads are provided on the inner sides of the front clamping plate 1 and the rear clamping plate 2, respectively, and the rubber pads have several through holes for bolts to pass through. The rubber pads increase the friction between the front clamping plate 1 and the rear clamping plate 2 and the groove plate 16, providing elastic deformation, so that the front clamping plate 1 and the rear clamping plate 2 can be firmly fixed to the groove plate 16 by bolts 4.
[0016] Furthermore, a shielding skin 14 is connected to the movable guardrail 6, covering the connection between the movable guardrail 6 and the fixed guardrail 5. The shielding skin 14 blocks the connection between the movable guardrail 6 and the fixed guardrail 5, preventing material from entering the connection and causing leakage.
[0017] Furthermore, the front clamping plate 1, the rear clamping plate 2, the fixed guardrail 5, and the movable guardrail 6 are made of cast iron or aluminum alloy, respectively. The guardrails need to have a certain impact resistance, wear resistance, and long service life.
