Description

Technical Field

[0001] The utility model relates to the technical field of mortar production equipment, and particularly relates to a batching and conveying device for mortar production. Background Technique

[0002] The batching device for mortar production is a key component in the mortar production line. It is responsible for accurately measuring and mixing various raw materials required for producing mortar according to a predetermined formula ratio. The raw materials required for mortar production, such as cement, sand, additives, etc., are stored in their respective storage bins. The raw materials are transported from the storage bins to the batching device through conveying equipment. During the batching process, according to the preset formula ratio, various raw materials are successively added to the metering and batching bin.

[0003] For example, the Chinese authorized patent "A Dry-Mixed Mortar Batching and Quantitative Conveying Device" with the publication number CN218019370U includes a frame and a quantitative hopper arranged on the frame. The quantitative hopper slides on the frame in a direction away from or close to the ground. A scale line is arranged inside the quantitative hopper. An outlet pipe is arranged at one end of the quantitative hopper close to the ground. A sealing plate for blocking the outlet pipe is arranged inside the outlet pipe. The sealing plate slides on the quantitative hopper in a direction perpendicular to the length direction of the outlet pipe. A pushing component for pushing the sealing plate to move is arranged on the frame. A conveying component for transporting the batching discharged from the outlet pipe into the mixing device is arranged on the frame.

[0004] Although the above-mentioned prior art can achieve the proportioning and conveying of mortar raw materials, during the quantitative weighing process, since the mortar powder is prone to wall hanging in the weighing cavity, it will affect the weight of the subsequent raw materials entering, resulting in the problem of reduced mortar preparation quality. Therefore, it does not meet the existing requirements. For this reason, we propose a batching and conveying device for mortar production. Content of the Utility Model

[0005] The purpose of the utility model is to provide a batching and conveying device for mortar production to solve the problem that the mortar powder is prone to wall hanging in the weighing cavity during the quantitative weighing process of the batching and conveying device mentioned in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A batching and conveying device for mortar production includes a frame and a mixing cylinder, and the mixing cylinder is fixed at the lower end inside the frame; it further includes:

[0007] A storage cylinder, which is arranged above the inside of the frame. There are at least three groups of storage cylinders, and a mortar raw material addition port is arranged at the upper end of each storage cylinder;

[0008] A weighing mechanism is arranged below the storage bin. A weighing cylinder is installed inside the weighing mechanism. Movable support blocks are installed at the lower ends on both sides of the weighing cylinder. Pressure sensors are installed on the inner wall of the weighing mechanism corresponding to the lower sides of the movable support blocks, and the detection ends of the pressure sensors are in contact with the bottoms of the movable support blocks. A vibration mechanism is arranged above the movable support blocks, and jitters are formed under collision to discharge the residual mortar raw materials in the inner cavity of the weighing cylinder.

[0009] A conveying mechanism is arranged below the mixing cylinder. The bottom of the conveying mechanism is communicated with the mixing cylinder through a discharge pipe. A mortar outlet is arranged below the other end of the conveying mechanism.

[0010] Preferably, the vibration mechanism includes a third motor, and the third motor is fixed on the inner upper part of the weighing mechanism. An eccentric wheel is installed on the output shaft of the third motor, and the eccentric end of the eccentric wheel contacts the side surface of the weighing cylinder every time it rotates one circle.

[0011] Preferably, one end of the movable support block extends into the inner wall of the weighing cylinder, and the movable support block is slidably matched with the weighing cylinder. A spring is installed between the movable support block and the weighing cylinder.

[0012] Preferably, a first motor is fixedly installed at the middle position of the bottom of the mixing cylinder. A first rotating shaft is installed on the output shaft of the first motor, and the first rotating shaft extends into the mixing cylinder. First stirring rods are welded and fixed on both sides of the first rotating shaft at the inner end in the mixing cylinder.

[0013] Preferably, a sleeve is installed outside the first stirring rod, and the sleeve is rotatably connected with the first stirring rod. A second stirring rod is fixedly installed outside the sleeve. A bevel gear is fixedly arranged at the outer end of the sleeve. A toothed ring is arranged in the inner wall of the mixing cylinder, and the toothed ring is meshed with the bevel gear.

[0014] Preferably, a second motor is installed at one end of the conveying mechanism. A second rotating shaft extending into the conveying mechanism is installed on the output shaft of the second motor. Spiral conveying blades are fixedly arranged outside the second rotating shaft.

[0015] Preferably, corrugated hoses are installed between the storage bin and the weighing mechanism, and between the weighing mechanism and the mixing cylinder.

[0016] Compared with the prior art, the beneficial effects of the present utility model are:

[0017] 1. The utility model is provided with a vibration structure in the weighing mechanism. The raw materials inside the storage bin enter the inside of the weighing bin through the corrugated hose. The movable support block applies pressure to the pressure sensor, so that the pressure sensor can accurately detect the weight of the incoming raw materials. After reaching the set value, the valve of the storage bin is closed, and the valve of the weighing bin is opened, so that the quantitatively measured mortar raw materials can enter the inside of the mixing bin. At the same time, the third motor is started, and its output shaft drives the upper eccentric wheel to rotate at a high speed. Every time the eccentric wheel rotates one circle, it will contact the weighing bin once. At a high frequency, the weighing bin will vibrate, so as to shake off the mortar raw materials adhering to the inner wall, ensuring that the weighing bin remains clean after detection, and providing a prerequisite for the accurate detection of subsequent mortar raw materials.

[0018] 2. The utility model is provided with a linkage type stirring mechanism. By starting the first motor, its output shaft drives the first rotating shaft to rotate, further driving the first stirring rods on both outer sides to rotate. The outer sleeves are used to mix the proportioned mortar raw materials in the horizontal direction to accelerate the full combination of each other. By installing bevel gears at one end of the sleeves, the bevel gears will do circular motion when the first stirring rods rotate, and engage with the toothed rings on the inner wall of the mixing bin, so that the sleeves are driven to rotate by themselves through the bevel gears. The upper and lower ends of the sleeve rods are provided with second stirring rods, and the rotation direction of the second stirring rods is perpendicular to that of the first stirring rods, so as to form a complex stirring motion inside the mixing bin, effectively improving the mixing effect between different mortar raw materials.
