Description

High-efficient little prefab concrete feeding machine

Technical Field

The invention belongs to the field of mechanical equipment for producing small concrete prefabricated parts, and particularly relates to a feeding machine system for the small concrete prefabricated parts.

Background

At present, most of small prefabricated parts still depend on manpower, the production efficiency is low, the labor intensity is high, and the demand of urban construction for the small prefabricated parts is increased day by day. Therefore, it is a necessary trend to realize automated production.

In the production of small preforms, the injection of concrete into the mould is a critical step. At present, more machines can realize the function of movable feeding, but fewer machines can be used in the field of small prefabricated part production. Generally, the mobile feeding can be realized by a screw feeding mechanism plus a moving mechanism.

The utility model patent CN202038703U provides a batcher is removed to fermentation storehouse material. The structure is not compact, and the gravity center is too high from the roller, so that the movement has larger impact. The material is pressed on the screw shaft in a large area, and when the shaft is long, the bearing is easy to lock. The screw shaft is integrated, so that the screw shaft is inconvenient to repair. Cannot withstand large axial loads.

Utility model patent CN205855198U provides a lithium cell raw materials screw feeder. The screw shaft and the shaft heads at the two ends are in interference fit to be unfavorable for overhauling. The bearings at the two ends cannot bear larger axial load due to the selected installation.

Disclosure of Invention

The invention aims to provide a flat rail concrete feeder which is used for producing small prefabricated parts, has high efficiency, simple and compact structure and is convenient to disassemble and repair, aiming at the prior technical defects and the requirements of small enterprises.

In order to achieve the purpose, the invention adopts the technical scheme that: the utility model provides a high-efficient concrete feeder for production of small-size prefab, sets up after the material loading, before the vibrations shaping, including spiral feed mechanism, running gear, large capacity hopper, overhead flat rail, first drive arrangement and second drive arrangement and the mounting bracket that corresponds, wherein spiral feed mechanism, running gear automobile body all weld on large capacity hopper, and the complete machine can be driven by first drive arrangement and be reciprocating motion on overhead flat rail, begins the ejection of compact when the discharge gate is facing to the mould on the below vibrations bench.

The feed inlet of the spiral feeding mechanism is welded with the large-capacity hopper, the spiral shaft is adopted for conveying, the material conveying distance is short enough, and materials cannot accumulate.

The spiral shaft is divided into an input shaft, a middle shaft with blades and a tail end shaft, wherein the input shaft and the middle shaft are connected in a crossed mode through two bolts, and the middle shaft and the tail end shaft are connected through one bolt.

The input shaft is positioned through the bearing with the bearing seat, and the bearing seat is internally provided with two angular contact ball bearings which are positioned completely, so that the spiral feeding mechanism can bear larger axial load, and the working condition of the second driving device is greatly improved.

The junction of end shaft and jackshaft sets up outside the drum, and end shaft is provided with the seat bearing, and the bearing frame is connected through a ring flange with the drum.

The flange plate is of a hollow structure and can extend into a tool to disassemble the connecting bolt.

Four corners of the traveling mechanism vehicle body are provided with bearings with seats, a driving shaft and a driven shaft are installed on the bearings, two mine car wheels are installed on the driving shaft and the driven shaft respectively, and a first driving device drives an input shaft through chain transmission.

The second driving device is installed on a mounting rack of the second driving device, one end of the mounting rack is welded on the spiral feeding mechanism, and the other end of the mounting rack is connected to the vehicle body, so that the strength is sufficient.

The first driving device is installed on a mounting rack of the first driving device, and the mounting rack is welded on a cylinder of the spiral feeding mechanism.

The spiral feeding mechanism is provided with materials by a large-capacity hopper, the materials can move along an overhead flat rail under the driving of the walking mechanism, discharging is started when the materials arrive above one die, 6 dies are arranged on the vibration platform, the materials are conveyed to the next procedure after vibration and tamping, the whole machine reciprocates at 6 stations, and the materials return to the initial position for feeding after being exhausted.

The invention has the beneficial effects that: the large-capacity hopper is arranged, and one-time feeding can meet the concrete consumption of a plurality of prefabricated parts. The spiral feeding mechanism and the traveling mechanism are mounted by depending on the hopper, so that the structure is compact, and meanwhile, the mounting design of the spiral shaft takes the convenience of disassembly and repair into consideration. Aiming at the characteristic of large axial load in actual production, the installation of the input end bearing is specially designed, the working condition of important parts is greatly improved, and the service life of equipment is prolonged. The concrete pouring device can replace the link of manually carrying materials to pour concrete into the mould, greatly improves the labor condition of workers, has simple and compact structure, is favorable for popularization and is convenient to dismantle and repair.
