2019-09-04

Avant-garde machinery takes you to see the belt conveyor installation standards on seed melon production line


1. When the bottom plate at the head and tail of the belt conveyor is soft, the cement foundation with a length of 2m, a width of 1.5m and a depth of 1m is fixed. The bottom bolt (φ 20mm) is embedded in the cement foundation not less than 700mm. When the bottom plate at the head and tail is hard, the ground anchor shall be used for fixing (the anchoring force shall not be less than 50KN), and the anchor bolts (φ 20mm) shall be cast in cement and buried in the bottom plate at least 1400mm.


2, the installation of belt conveyor must be head, tail fixed firmly, smooth operation. The bottom belt shall not be less than 400mm from the bottom plate, and the lowest point of the tail drum shall not be less than 150mm from the bottom plate. Installation test run to flat, straight, stable, nose, fuselage, tail center in a straight line.
