Description

Technical Field

[0001] The utility model relates to the technical field of construction, in particular to a quantitative feeding device for pouring prefabricated parts. Background Art

[0002] Precast concrete parts are semi-finished or finished components that are pre-processed and formed at a prefabrication plant or construction site using concrete materials according to the requirements of design drawings. After reaching a certain strength, they are transported to the construction site for direct installation.

[0003] When producing prefabricated parts, most of them are made by mold casting. After the mold is filled with concrete, there will be leftover concrete in the hopper. If it is not cleaned for a long time, the concrete will sink to the bottom of the hopper or even clump and cannot be used. For this reason, the application discloses a quantitative feeding device for prefabricated part casting to solve the problem of leftover concrete in the hopper after casting, and to solve the problems of caking and sinking to the bottom. Utility Model Content

[0004] The utility model aims to solve the existing problems and provides a quantitative feeding device for casting prefabricated parts.

[0005] The utility model is realized through the following technical scheme: a quantitative feeding device for casting prefabricated parts, comprising a hopper, a frame is installed outside the hopper, a weighing sensor is connected below the peripheral corner of the frame, the lower end of the weighing sensor is installed on a bracket, a motor frame is arranged above the bracket, a stirring motor is installed on the motor frame, the output shaft of the stirring motor is connected to a stirring shaft, a stirring rod is connected to the stirring shaft, and a discharging mechanism is arranged at the end of the lower port of the hopper.

[0006] As a further improvement of the above scheme, the discharge mechanism includes a bottom plate, which is covered and arranged at the lower port of the hopper. The bottom plate is connected to side plates on both sides, and the outer ends of the side plates are connected to end plates. The end plates are connected to cylinders. The telescopic rod of the cylinder passes through the end plates and is connected to the outer side of the lower end of the hopper. The position of the bottom plate relative to the lower port of the hopper is controlled by the cylinder to cover the lower port of the hopper and offset it outside the lower port of the hopper. Guide columns are installed in the waist holes on the side plates on both sides of the bottom plate, and the guide columns are connected to the outer side of the lower port of the hopper. The end plates are used to install the cylinders. The cylinders work to pull the bottom plate to move through the end plates, and the side plates are guided by the guide columns during the displacement process.

[0007] As a further improvement to the above solution, the discharge mechanism is symmetrically arranged on the discharge port of the hopper, and the discharge of the concrete in the hopper is controlled by the discharge mechanism with a split structure.

[0008] As a further improvement of the above scheme, the hopper consists of three parts, including an upper barrel, a middle hopper body and a lower hopper tube. The lengths of the stirring rods in the barrel, the hopper body and the hopper tube are different, and the length of the stirring rods becomes shorter from the upper barrel to the middle hopper body and the lower hopper tube.

[0009] Compared with the prior art, the utility model has the following advantages: simple structure, reasonable design, novel and unique concept, quantitative weighing of the hopper and the materials contained therein by a weighing sensor, and then control of the discharge of the materials by a discharging mechanism, and in addition, a hoisted stirring shaft is suspended in the hopper to stir the materials to avoid material agglomeration and sinking to the bottom.

[0015] As a further improvement to the above scheme, the discharging mechanism 3 includes a bottom plate 31, which is covered and arranged at the lower port of the hopper 1. The bottom plate 31 is connected to side plates 32 on both sides, and the outer ends of the side plates 32 are connected to the end plates 3. The end plates 3 are connected to the cylinders 34. The telescopic rod of the cylinder 34 passes through the end plates 3 and is connected to the outer side of the lower end of the hopper 1.
