Detailed ways

The specific embodiments of the present utility model will be further described below with reference to the accompanying drawings. It should be noted here that the description of these embodiments is used to help the understanding of the present invention, but does not constitute a limitation of the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as there is no conflict with each other.

A high-efficiency rotor sand mixer, as shown in Figure 1, includes a base and a sand mixing cylinder arranged on the base. Since the internal rotational vibration of the equipment is relatively severe when in use, the sand mixing cylinder is set on the base. , and the base is fixed on the ground by bolts or welding, which can ensure the safety of the equipment during use and prevent the equipment from tilting or collapsing.

Specifically, in the embodiment of the present invention, four pillars are evenly arranged around the base, and the sand mixing cylinder is fixed on the four pillars.

In the embodiment of the present utility model, two stirring devices are arranged symmetrically in the sand mixing cylinder, the inner bottom of the sand mixing cylinder is provided with a rotating device, the sand mixing cylinder is provided with a feeding port, and the bottom side wall of the sand mixing cylinder is provided with a rotating device. A discharge port is provided, and a cover is installed on the discharge port.

Specifically, in the embodiment of the present invention, the stirring device has the following structure: the stirring device includes a rotor motor and a stirring body, and the stirring body includes a rotating shaft and a plurality of rotor blades horizontally arranged on the rotating shaft, and the rotating shaft is in the rotor motor. Rotate under drive.

Wherein, at least four rotor blades are arranged on the rotating shaft. In the embodiment of the present invention, there are four rotor blades arranged on the rotating shaft. In order to stir evenly, the arrangement direction and position of the four rotor blades can be irregular structures. , for the convenience of description, in the embodiment of the present invention, the four rotor blades are arranged horizontally on the rotating shaft.

In the embodiment of the present utility model, the rotating device has the following structure: the rotating device includes a gearbox and a scraper body, the scraper body includes a scraper shaft and a scraper horizontally arranged on the scraper shaft, and the scraper shaft and the speed changer The shaft of the box is fixedly connected, and the scraper shaft rotates under the drive of the gearbox.

Among them, the gearbox is fixed on the base.

The high-efficiency rotor sand mixer of the present utility model is used as follows:

The old sand and auxiliary materials (such as clay, binder, etc.) and other raw materials are put into the sand mixing cylinder from the feeding port, the stirring device and the rotating device are turned on, and the rotor blades will rotate around the rotating shaft under the drive of the rotor motor to stir the raw materials. At the same time, the scraper is driven by the gearbox to rotate around the scraper shaft, and the raw materials at the bottom of the sand mixing cylinder are turned over and stirred; after the mixing is uniform, the stirring device and the rotating device are closed, and the cover on the discharge port is opened to mix evenly. The raw material falls from the discharge port to complete the sand mixing work.

The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, without departing from the principle and spirit of the present invention, various changes, modifications, substitutions and alterations can be made to these embodiments, which still fall within the protection scope of the present invention.
