Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a concrete feeding device for building construction. Background Technology

[0002] Concrete plays an extremely important role in building construction. It is one of the most important civil engineering materials in modern times. Concrete is made by mixing cement as a binder with aggregates such as sand and stone and water in a certain proportion. In actual construction activities, workers often need to use concrete feeding devices to assist in feeding materials and improve construction efficiency.

[0003] Concrete feeding devices for building construction typically transport pre-mixed concrete to the construction site using concrete trucks. This method has limitations, such as the inability to flexibly mix concrete according to actual needs. Furthermore, the three types of raw materials used in concrete preparation require manual metering and pouring by the user, making it difficult to achieve intelligent quantity control, batching, and replenishment functions, which affects the working efficiency of the device. Based on these issues, we propose a novel concrete feeding device for building construction. Utility Model Content

An automatic liquid metering pump for water supply and a water replenishment pump are respectively installed on both sides of the top of the water storage shell. The concrete mixing tank is placed at one end of the raw material transport vehicle using an automatic liquid metering pump. Inclined screw conveyors matching the material supply pump are installed on both sides of one end of the concrete mixing tank. The top of the integrated industrial control computer is equipped with an inclined feed inlet and a threaded water inlet matching the inclined screw conveyors and the automatic liquid metering pump. A concrete dispensing port is located at the top of the concrete mixing tank. Mixing servo motors are installed at both ends of the concrete mixing tank. The output end of each mixing servo motor is connected to a mixing shaft. Electrothermal ceramic heating elements are evenly installed on the mixing shaft. A temperature sensor is installed at one end inside the concrete mixing tank.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) The concrete feeding device for construction uses a concrete mixing box, which optimizes its performance. By setting the device to consist of two parts, a raw material transport vehicle for conveying concrete raw materials and a concrete mixing box for mixing and preparing concrete, it solves the problems of fixed concrete ratio, difficulty in adjusting at any time, easy solidification of concrete on the inner wall of the vehicle, and difficulty in replenishing concrete raw materials that exist in a simple concrete feeding vehicle. In actual use, the raw material transport vehicle flexibly transports various raw materials that make up the concrete to the construction area and parks it so that the guide pipe of the material pump for feeding is aligned with the feeding trough at the bottom of the inclined screw conveyor. At this time, the material pumps on the cement cement storage shell and the sand and gravel aggregate storage shell can automatically pump the cement cement and sand and gravel aggregate into the inclined screw conveyor in sequence, and then discharge them through the discharge trough at the top of the inclined screw conveyor. The material is lifted and fed into the inclined inlet at the top of the concrete mixing tank. During this process, the weighbridges, which are fixed in sequence on the raw material transport vehicle and match the cement binder storage shell and the aggregate storage shell, can independently monitor the weight changes of the cement binder storage shell and the aggregate storage shell in real time. The monitored data is sent to the industrial control computer. After the industrial control computer calculates and processes the data, it can intelligently control the amount of cement binder and aggregate extracted each time. Secondly, the automatic liquid metering pump for water supply on the water storage shell is started. Clean water is pumped quantitatively through the flexible water guide hose connected to the threaded water inlet on the concrete mixing tank. Thus, the device can automatically and quantitatively supply cement binder, aggregate and clean water into the concrete mixing tank according to the actual required concrete mix ratio. This makes the device realize the function of flexible quantitative batching and has strong applicability.

[0015] (2) The concrete feeding device for building construction is equipped with an automatic liquid metering pump for water replenishment, which allows the user to move the concrete mixing box to a suitable construction location during actual operation. Then, the raw material transport vehicle can freely drive between the concrete mixing box and the raw material storage bin. Next, the corresponding material pumps installed on the cement binder storage shell and the sand and gravel aggregate storage shell can be started. The cement binder and sand and gravel aggregate can be automatically replenished into the corresponding cement binder storage shell and sand and gravel aggregate storage shell on the top of the raw material transport vehicle through the corresponding material guide pipe. This makes it easy to replenish concrete raw materials and solves the time-consuming and labor-intensive problem of manually lifting and pouring materials into the vehicle body by workers in the traditional way. In addition, the automatic liquid metering pump for water replenishment on the water storage shell can be started to directly pump clean water into the water storage shell on the top of the raw material transport vehicle through the flexible water guide hose, which further improves the convenience of concrete raw material replenishment operation.

[0016] (3) The concrete feeding device for building construction is equipped with temperature sensors, which optimizes the structure of the device. On the one hand, the two mixing servo motors on the concrete mixing box are started, which drive the corresponding mixing shaft to rotate inside the concrete mixing box. With the heating function of the electric heating ceramic heating element and the temperature monitoring function of the temperature sensor, the raw materials quantitatively introduced into the concrete mixing box can be mixed and heated at controlled temperature. This is beneficial to improve the uniformity of the final concrete product, accelerate its molding process, and improve efficiency. On the other hand, by installing a vibrator on the outer wall of the inclined feed port, it is convenient to use the vibration force of the vibrator to promote the discharge of materials inside the inclined feed port and avoid blockage.
