AI Technical Summary

Technical Problem

During the restoration of hollow trunks of ancient and famous trees, the inconvenience of storing pipes can easily lead to improper handling or detachment, affecting their service life. At the same time, the curing effect of the filling material is limited.

Method used

A layered filling and curing molding device was designed, comprising a supporting base plate, a mixing tank, a stirring rod, a pump body, and a nozzle. The stirring rod mixes the filler, the pump body delivers the filler, and the support base and locking pins fix the pipeline to ensure pipeline stability. The nozzle is detachable for easy use. The water tank and pump body keep the tree hole moist to promote the hardening of the filler.

Benefits of technology

It improves the placement capacity of pipes and the storage capacity of tools, while ensuring the curing effect of the filling material and the humidity of the environment around the tree hole, thus extending the service life of the equipment and the filling efficiency.

Abstract

The utility model relates to the technical field of ancient and famous tree trunk cavity repairing, and discloses a layered filling and curing forming device for ancient and famous tree trunk cavity repairing, which comprises a supporting bottom plate and a mixing box, the mixing box is fixed at the right side of the top of the supporting bottom plate, and a bayonet lock is inserted between a front connecting plate and a rear connecting plate. The outer portions of the two ends of the clamping pin are connected with locking nuts. According to the utility model, the required filler is fed into the mixing box through feeding at the position of the feeding hole, and when filling is not needed, the two supporting seats can be adjusted to be close to the external position of the second pipeline, and then after the bayonet lock is inserted at the position of the connecting plate, the position is locked by adopting the locking nut, so that the filling is completed. And when the device needs to be used, a locking nut can be detached, then the outer portion of the second spray head is held, the second pipeline is stretched in a matched mode through the first corrugated pipe, the second spray head finally carries out filling work, and the placing capacity of the pipeline is facilitated.
