Because there is the gap between guide chute and the conveyer belt, the gap also constantly strengthens along with the increase of feed distance simultaneously, and the material is possible to be followed this gap and outwards diffused like this to the lower part of batcher conveyer belt is rolled over from the conveyer belt both sides, brings the influence to the operation of belt feeder, is greater than the distance between guide chute and the conveyer belt outer edge 1.5 times of maximum gap height between guide chute and the conveyer belt, can effectual prevention material roll over conveyer belt border.
The baffle plate of macromolecular polyethylene material is arranged outside the guide chute, and the distance between the installed baffle plate and the outside of the guide chute is more than 1.2 times of the maximum clearance between the guide chute and the conveying belt, so that even if the material overflows from the gap between the guide chute and the conveying belt in the feeding process, the material cannot flow out to the lower part of the conveying belt to cause harmful influence on the operation of the belt feeder due to the limitation of the baffle plate. If some particles enter the gap between the material guiding plate and the conveying belt, the small amount of the particles and the small dynamic friction coefficient and certain elasticity of the high molecular polyethylene can produce small harmful effect and small influence on the weighing precision of the belt weigher.
The high molecular polyethylene lining plate is laid inside the material guide chute, and when materials are fed in the material guide chute, the high molecular polyethylene dynamic friction coefficient is small, and the mutual friction between the materials is small, so that the influence of the materials on the action pressure fluctuation on the belt scale, which possibly occurs in the moving process in the material guide chute, can be reduced, and the weighing precision of the belt scale is improved.
