Heavy Duty Apron Feeder

Abstract

The invention discloses a heavy type plate feeder, and belongs to the technical field of mining machines. The heavy type plate feeder comprises a base, cross beams, caterpillar track guide wheel seats, caterpillar track guide wheels, a raw mineral material conveying mechanism and a caterpillar track wheel shaft. The raw mineral material conveying mechanism comprises a pair of caterpillar track plate traction chains and a set of caterpillar track plates, a pair of caterpillar track wheels is sleeved with the caterpillar track plate traction chains, and a caterpillar track tensioning mechanism is arranged at the right end of the base. The heavy type plate feeder is characterized in that every two cross beams arranged on the upper portion of the base are adopted as a group, cross beam limiting frames are fixed to the base, a shock pad barrier strip and shock pads are further arranged on the base, the two ends of each cross beam are arranged on the shock pads, and shock pad blocking and protecting mechanisms are fixed to the positions corresponding to the shock pads. The caterpillar track tensioning mechanism comprises a support cross beam, a first support cross beam longitudinal arm, a second support cross beam longitudinal arm, an adjusting screw rod, a spring and an adjusting nut. The heavy type plate feeder is beneficial for protecting the raw mineral material conveying mechanism, the cross beams and the base against impact failures, and a caterpillar track wheel bearing pedestal can be reliably tensioned and located at the adjusted position.

Description

technical field [0001] The invention belongs to the technical field of mining machinery, and in particular relates to a heavy-duty apron feeder, which is used for transporting mineral raw materials such as limestone and coal to a crusher for crushing them. Background technique [0002] The technical information about the apron feeder can be found in the published Chinese patent documents. For example, the utility model patent authorization announcement number CN201095529Y recommends "large-capacity heavy-duty apron feeder". Overlapping conveying troughs are installed on the joints, and the conveying trough is designed as an integrated structure composed of a plane section and an arc section. The effect is positive. Another example is that the invention patent application publication number CN103359451A provides a "panel feeder". The technical points of the patent application scheme are: a skirt protruding downward is formed on both sides of the conveying trough plate, and t...

Problems solved by technology

However, due to the defect in this patent that it is difficult to tighten the bearing seat of the chain rail wheel and maintain it at the adjusted position, it is difficult to guarantee the movement effect of the chain rail plate traction chain as a chain rail mechanism, that is, as a mineral raw material conveying mechanism
