A safety protection device for the angular torque protection a material groove edge of a material unloading door of a sand transport truck

Abstract

The invention discloses a safety protection device for the angular torque protection groove edge of a material unloading door of a sand transport truck, Its structure includes: loading and unloading groove, Edge-sealing baffle, hanger spindle disk, door panel, A load and unloading groove is mechanically connected with that door panel through a hanger rotate shaft plate, two edge sealing baffles are respectively inserted and fitted on the top of the left and right sides of the loading and unloading grooves, the inclined panel is horizontally welded at the bottom of the front side of the loadingand unloading groove, the hanger rotating shaft plate is provided with two and is respectively arranged at the upper left corner and the upper right corner of the front side of the loading and unloading groove, A suspension frame rotate shaft plate is matched with a door plate, the loading and unloading groove lifts and opens the door panel to unload the sand grains, The self-weight of the door plate flips and fits on the left side of the loading and unloading groove along the truss rod and the sleeve cap, and the truss rod rotates and pushes the sliding mechanism to limit the sliding angle between the pulley and the spring elbow pipe, thus avoiding the friction with the chamfer of the loading and unloading groove when the door plate is reset, and achieving the effect of angular torque protection and sealing edge.

Description

technical field [0001] The invention relates to a safety protection device for an angular torque protection trough edge of a discharge door of a sand truck, and belongs to the field of safety protection devices for a discharge door. Background technique [0002] The sand truck is a type of dump truck, which is specially used to transport and load sand. During the sand unloading process, the unloading chute is lifted, and the unloading door will be slowly opened to dump the sand. However, after the unloading is completed, The reset of the self-unloading door will slap the edge of the unloading chute, scratching and damaging the corner structure of the unloading chute. The disadvantages to be optimized in the current technology are: [0003] After the unloading chute is unloaded, the door panel will be reset by the self-weight flip of the roller to drive the inertia to slap the discharge port. The edge of the door panel frequently collides with the edges and corners of the gro...

AI Technical Summary

Problems solved by technology

[0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a safety protection device for the angular torque protection of the edge of the chute for the discharge door of a sand truck, so as to solve the problem that after the discharge chute is unloaded, the door panel will be reset by the rollers. The self-weight flip drives the inertia to slap the discharge port, and the edge of the door panel frequently collides with the edges and corners of the groove frame. If the notch is rubbed and smoothed for a long time, there will be a gap at the bottom edge, which will cause leakage during the sand discharge and transportation process. question
