Description

Technical Field

[0001] This patent relates to the field of batching machines, specifically a batching machine with a protective structure. Background Art

[0002] Batching, the process of mixing certain raw materials in a certain proportion during the production process. Batching equipment is classified into weighing batching and volumetric batching according to its working mode. Batching machines, also known as aggregate batching machines, are used in concrete or asphalt mixing plants to store and measure various sand and gravel aggregates and deliver them to the mixer according to a pre-set formula to mix with cement, fly ash, mineral powder, additives, water, etc. to form concrete;

[0003] However, the batching machine in the existing technology still has some shortcomings. For example, it does not have feeding protection. When loading, the material is often loaded manually or by a conveyor belt. However, manual loading is inefficient, so a conveyor belt is used to realize automatic loading. However, the traditional conveyor belt will continue to work after it is started, so it will continue to load the material. As a result, the batching and loading will face the problem of material leakage if the loading speed is greater than the extrusion speed, and vice versa, there will be a shortage of supply. Therefore, the existing technology needs to be improved. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this patent is to provide a batching machine with a protective structure.

[0005] The technical solution adopted by this patent to solve its technical problem is: a batching machine with a protective structure, comprising a batching machine body, a sealing cover is installed on the top of the batching machine body, and feeding pipes are installed on both sides of the upper end of the sealing cover;

[0006] The top of the feed pipe is equipped with a feed hopper, and a feeding protection structure is installed in the feed hopper. The feeding protection structure includes a cross bar, an electric push rod, an annular pad and an umbrella-shaped cylinder;

[0007] The cross bar is installed in the feed hopper, the electric push rod is installed on the cross bar, the annular pad is installed in the feed hopper, and the umbrella-shaped tube is installed on the output end of the electric push rod;

[0008] A through hole is provided on the side wall of the feed hopper, and a tuning fork level meter is installed in the through hole.

[0009] Furthermore, a rotating shaft is assembled inside the main body of the batching machine, a coupling is assembled at the top end of the rotating shaft, a servo motor is assembled at the top middle section of the sealing cover, and the rotating shaft is connected to the driving end of the servo motor through the coupling.

[0010] Furthermore, the outer wall of the rotating shaft is evenly sleeved with fixed sleeves from top to bottom, and stirring plates are installed at both ends of the outer wall of each fixed sleeve.

[0011] Furthermore, each end of the stirring plate is equipped with a breaking spring.

[0012] Furthermore, a screw is installed on the output end of the electric push rod, a thread groove is opened in the umbrella-shaped tube, and the screw is sleeved in the thread groove.

[0013] Furthermore, a carrying ring is sleeved on the outside of the batching machine body, and support rods are installed around the side walls of the carrying ring. A discharge pipe is installed at the bottom end of the batching machine body, and a valve is installed on the discharge pipe.

[0014] The beneficial effects of this patent are:

[0015] A batching machine with a protective structure has a simple structure and is easy to operate. By arranging two loading hoppers at the upper end of the batching machine, different types of raw materials can be added to the batching machine for batching. When the raw materials are put into the feed hopper, the output end of the electric push rod drives the umbrella-shaped cylinder to move upward and leave the annular pad, and the raw materials are discharged. If they do not pass the tuning fork level meter, the raw materials enter the batching machine through the feed port for stirring. When the liquid level of the discharged raw materials is lower than the tuning fork level meter, the output end of the electric push rod drives the umbrella-shaped cylinder to move upward automatically, thereby realizing automatic loading and avoiding the disadvantages of manual or conveyor belt loading.

The model of the tuning fork level meter 7 is UKL5745. The tuning fork level meter 7 is connected to an external controller. If the liquid level below the feed hopper 3 is insufficient, the tuning fork level meter 7 will transmit a signal to the external controller, and the controller will control the operation of the electric push rod 402 through the control module.
