Technical Field
[0001] This utility model relates to the field of repair technology for hollow trunks of ancient and famous trees, specifically a layered filling and curing molding device for repairing hollow trunks of ancient and famous trees. Background Technology
[0002] Hollow trunks in ancient and famous trees are mainly caused by factors such as xylem decay, pests and diseases, natural disasters, and human factors. Ancient trees have a long lifespan, making their xylem prone to decay, loosening, and hollowing. In addition, external factors such as pruning, pests and diseases, and natural disasters can also cause damage and rot, forming cavities. To prevent these cavities from expanding and causing widespread trunk decay or even hollowing, thus affecting the tree's health and lifespan, cavity repair work is necessary.
[0003] The restoration of cavities in the trunks of ancient and famous trees requires layered filling and curing. Commonly used filling materials for this purpose include epoxy resin, unsaturated resin mixed with talcum powder, and cementitious materials. These materials are waterproof, durable, and high-strength, effectively supporting and protecting the trunk and preventing further rot and moisture intrusion. However, layered filling requires the use of pipes to transport the filler. If the pipes are not conveniently stored, they are prone to improper handling or detachment, affecting their lifespan. Utility Model Content

If the pipes are not convenient to store during operation, improper handling or detachment may occur, affecting the service life of the pipes.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a layered filling and curing molding device for repairing cavities in the trunks of ancient and famous trees, comprising a supporting base plate and a mixing box. The mixing box is fixed at the right side of the top of the supporting base plate. A working motor is installed on the top of the mixing box, and a stirring rod is driven to the output end of the working motor. A first pump body is installed on the top of the supporting base plate. One end of the first pump body is connected to a first pipe, and the other end of the first pump body is connected to a second pipe. A section of first corrugated pipe is fitted in the middle of the second pipe, and a second nozzle is connected to the tail end of the second pipe. Support rods are pivotally installed at the front and rear positions of the top of the supporting base plate. A support base is fixed to the top of the support rod. A protective pad is glued and fixed to the end face of the support base. A connecting plate is fixed to the top of the support base. A locking pin is inserted between the front and rear connecting plates, and locking nuts are connected to the external ends of the locking pin.
[0006] As a further technical solution of this utility model, the outer side wall of the front and rear positions of the locking pin is fixed with an external thread end, and a locking nut is threadedly connected to the external thread end.
[0007] As a further technical solution of this utility model, the mixing box is provided with feed inlets on both sides of the top, and the stirring rod is provided with stirring blades evenly fixed on both sides.
[0008] As a further technical solution of this utility model, a driven wheel is installed on one side of the bottom of the support base plate, and a driving wheel is installed on the other side of the bottom of the support base plate.
[0009] As a further technical solution of this utility model, a water tank is installed at the rear position on one side of the top of the support base plate, and a water inlet is connected and installed at the upper position on the side of the water tank.
[0010] As a further technical solution of this utility model, a second pump body is installed on the top of the water tank. One end of the second pump body is connected to a first drain pipe, and the other end of the second pump body is connected to a third pipe. A section of second corrugated pipe is arranged in the middle of the third pipe, and a first nozzle is connected to the tail end of the third pipe. A pipe support frame for supporting the third pipe is installed on the top of the water tank.
[0011] As a further technical solution of this utility model, a fixed base plate is fixed to the side of the supporting base plate by bolts, and a tool placement box is installed on the top of the fixed base plate, with a sponge pad laid at the bottom inside the tool placement box.
[0012] As a further technical solution of this utility model, the top of the tool storage box is covered with a cover plate, and side plates are fixed on both sides of the bottom of the cover plate. Fixing bolts for connection are assembled between the side plates and the tool storage box.
[0013] Compared with the prior art, the beneficial effects of this utility model are: the layered filling and curing molding equipment for repairing the hollow trunks of ancient and famous trees not only improves the pipe placement capacity, but also improves the curing capacity and tool storage capacity of the layered filling and curing molding equipment.
[0014] (1) By feeding the required filler into the mixing box through the feed inlet, the working motor is started and the stirring rod is rotated to mix the filler in the mixing box. Then the first pump is started and the filler is extracted by the action of the first pipeline and output through the second pipeline. When filling is not required, the two support seats can be adjusted to the outside of the second pipeline. The two support seats are used to clamp the filler while the protective pad is used for contact protection. After inserting the pin at the connecting plate, the locking nut is used to lock the position, which facilitates the support of the second nozzle at the end of the second pipeline. When it is needed, the locking nut can be removed, and the outside of the second nozzle can be held. The first corrugated pipe is used to stretch the second pipeline so that the second nozzle can finally perform the filling work. This facilitates the placement of the pipeline.
[0015] (2) By assembling the water tank at the rear of the top of the support base plate, fixing the scale line for observation on the front face of the water tank, and installing the second pump body at the top of the water tank, the second pump body is started after the filling is completed. The water source is drawn by the first drainage pipe, and then the water is diverted at the position of the third pipe, and finally sprayed by the first nozzle. This ensures that the tree hole and its surrounding environment are moist, so as to promote the hardening of cement or other fillers. At the same time, excessive pressure is avoided on the filling cement to avoid damaging the cement layer.
[0016] (3) By using bolts to fix the base plate to the side of the support base plate, the tool storage box is assembled on the top of the base plate. A layer of sponge pad is laid inside the tool storage box, and the tools are placed on the sponge pad for protection. Therefore, tools such as scrapers or wooden sticks used for compaction can be stored in the tool storage box during work, which improves the temporary storage capacity of tools.
