Description

Technical Field

[0001] The utility model belongs to the technical field of concrete production, and in particular relates to a concrete nozzle structure for concrete production. Background Art

[0002] Concrete, as an engineering composite material composed of aggregates (such as sand and stone) bonded together by cementitious materials (such as cement), has been widely used in the field of civil engineering due to its excellent physical and chemical properties. In actual construction, commercial concrete is usually used directly for construction. In the production process of concrete, the concrete nozzle structure plays a vital role, responsible for discharging the produced concrete evenly and accurately to the designated location. However, the existing concrete nozzle structures on the market currently have some obvious deficiencies in design and function.

[0003] First, these nozzle structures often only have a single concrete discharge function and lack an effective mechanism to adjust the concrete discharge speed. In practical applications, due to construction needs, it may be necessary to adjust the concrete discharge speed in different situations, but the existing nozzle structure cannot meet this demand, thus limiting the construction efficiency and the control of concrete quality.

[0004] Secondly, due to the special physical and chemical properties of concrete, such as easy coagulation and hardening, the nozzle structure is prone to accumulate concrete and coagulate into blocks after a period of use, thus affecting the discharge effect and service life of the nozzle. In order to solve this problem, the common practice at present is to stop the machine for cleaning when the nozzle is blocked or needs to be cleaned, which not only increases the construction cost, but also affects the construction progress.

[0005] Therefore, it is very necessary to invent a concrete nozzle structure for concrete production. Utility Model Content

[0006] The purpose of the utility model is to provide a concrete nozzle structure for concrete production to solve the problems mentioned in the background technology.

[0007] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0008] The utility model discloses a concrete nozzle structure for concrete production, comprising a fixing frame, a guide frame, a rack, a gear, a first motor and a discharge pipe, wherein the fixing frame is fixed to the end of the material delivery pipe through a joint, wherein the inside of the fixing frame is slidably mounted with the guide frame through a slideway; the outer side surface of the guide frame is fixed with a rack through bolts, wherein the outer side surface of the rack is meshed with a gear; the gear is fixed to the output end of the first motor, wherein the first motor is fixed to the fixing frame through bolts; the lower end of the fixing frame is fixed with the discharge pipe through a joint, and the other end of the discharge pipe is arranged inside the concrete processing equipment.

[0009] Furthermore, the guide frame includes a frame body, an acceleration chamber, an impeller, a guide chamber and a partition, the frame body is slidably installed inside the fixed frame through a slide, and a rack is fixed to the outer side of the frame body by bolts; an acceleration chamber is opened inside the frame body, wherein the two impellers are rotatably installed inside the acceleration chamber through support bearings; one end of the impeller is fixed to the output end of the corresponding second motor, and the second motor is fixed to the outer side of the frame body by bolts; a guide chamber is opened inside the frame body, wherein a partition is arranged between the guide chamber and the acceleration chamber, and the partition is fixed to the inner wall of the frame body. Such an arrangement can increase the discharge speed of concrete during normal use and is convenient for cleaning. Secondly, when there is no need to discharge concrete, the feed pipe can be blocked.

[0010] Furthermore, the diameter of the guide cavity is the same as that of the feed pipe and the discharge pipe, and chamfers are provided at both ends of the guide cavity. Such a configuration enables the concrete to be temporarily guided through the guide cavity when the acceleration cavity needs to be cleaned.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] The setting of the guide frame of the utility model can, during normal use, connect the acceleration chamber with the material delivery pipe and the discharge pipe, so that the concrete inside the material delivery pipe passes through the acceleration chamber and enters the discharge pipe. At this time, the impeller can be driven to rotate by the second motor, so that the concrete is accelerated by the rotation of the impeller, thereby increasing the discharge speed of the concrete. After a period of use, the guide chamber can be connected with the material delivery pipe and the discharge pipe through the cooperation of the first motor, the gear and the rack, that is, the concrete inside the material delivery pipe passes through the guide chamber and enters the discharge pipe. At this time, due to the leakage of the acceleration chamber, the staff can clean the inside of the acceleration chamber. When it is not necessary to discharge the concrete, the first motor, the gear and the rack can be cooperated to make the frame block the material delivery pipe. BRIEF DESCRIPTION OF THE DRAWINGS
