Description

A vibrating screening machine

technical field

The utility model relates to the technical field of vibrating screening machines, in particular to a vibrating screening machine.

Background technique

The vibrating screening machine works by using the vibrating motor as the reciprocating rotary vibration generated by the vibration of the vibrator.

At present, in related technologies, most of the existing material screening methods require multiple screenings, the screening efficiency is low, and there is still a mixture of coarse and fine materials after screening; after screening, the screened materials need to be screened After the collection, the sieving process is carried out again, and the sieved materials cannot be collected and processed at the same time of sieving, resulting in that the time of screening and collection cannot be overlapped, which wastes time.

Utility model content

Based on the technical problems existing in the background technology, the utility model proposes a vibrating screening machine.

A vibrating screening machine proposed by the utility model includes a screening cylinder, a support frame and a vibrating motor. The top of the cylinder is provided with a vertically downward screening groove, and a conical bucket arranged up and down and a conical stepped screening net are installed in the screening trough, and the conical stepped screening net is a cone structure. And the outer circumference of the conical ladder screen is arranged in steps, the screen cylinder is provided with a discharge port in the upper direction and the discharge port is located at the bottom periphery of the tapered screen screen, and the screen is sleeved with The receiving ring, the receiving ring is provided with a collection groove, and the collection groove is connected with the discharge port.

Preferably, the shock absorbing mechanism includes a spring shock absorber, and the outer wall of the screening cylinder is installed on the supporting frame through a tapered stepped screening net.

Preferably, a disassembly cylinder is threaded on the screening cylinder, and the tapered bucket is installed in the disassembly cylinder.

The utility model has the following beneficial effects: through the set screening cylinder, support frame, conical bucket, conical ladder screening net, material receiving ring, vibrating motor and shock absorbing mechanism, it is convenient for the equipment to screen materials at the same time. At the same time, the screened large-grained materials are taken out for re-screening or other processing, reducing unnecessary waste of time, reducing the impact of the vibration motor on the support frame, and ensuring the stability of the entire equipment placement.

Detailed ways

Referring to Figure 1-2, the utility model proposes a vibrating screening machine, including a screening cylinder 1, a support frame 2 and a vibrating motor, wherein:

The screening cylinder 1 is installed on the support frame 2 through the shock absorbing mechanism, and the vibrating motor is installed on the screening cylinder 1. The top of the screening cylinder 1 is provided with a vertically downward screening groove, and the screening groove is installed with a The conical bucket 3 and the conical stepped screening net 4 are arranged up and down. The conical stepped screening net 4 is a cone structure and the outer circumference of the conical stepped screening net 4 is arranged in a stepped manner. A discharge port is provided to the direction and the discharge port is located at the bottom periphery of the conical ladder screen 4, a collection ring 5 is set on the screening cylinder 1, and a collection tank is provided on the collection ring 5, and the collection tank Connected with the discharge port;

The cross-sectional view of the conical ladder screen 4 is shown in Figure 2. During the screening work, the material can be poured into the screening tank through the conical bucket 3, and the material will fall through the small diameter of the conical bucket 3. At the conical top position of the conical ladder screen 4, the vibrating motor drives the entire screening cylinder 1 to vibrate and drives the conical ladder screen 4 to vibrate, so that the materials are filtered and screened on the conical ladder screen 4 , materials with large particles will roll and slide down along the stepped inclined surface of the conical stepped screen 4, and the stepped setting can prolong the time for the materials to roll down, so that the materials that can be screened can be screened. , the large-grained material rolls down through the surface of the conical ladder screen 4 and rolls down through the discharge port into the collecting tank of the receiving ring 5, which can facilitate the staff to screen the filtered large-grained material again or Carry out other processing to reduce the waste of time required to disassemble the machine to clean the large particles of the screen;

The function of the conical bucket 3 can ensure that the material can diffuse and slide downward from the middle part of the conical end of the conical step screen 4 .

In a specific embodiment, the damping mechanism includes a spring shock absorber 6, and the outer wall of the screening cylinder 1 is installed on the support frame 2 through the conical ladder screening net 4;

The impact of the vibration of the vibration motor on the support frame 2 can be reduced by the spring shock absorber 6 .

In a specific embodiment, a detachable cylinder 7 is threaded on the screening cylinder 1, and the tapered bucket 3 is installed in the detachable cylinder 7;

It can facilitate the disassembly of the conical bucket 3, so as to facilitate the cleaning of the conical ladder screen 4.

The above is only a preferred embodiment of the utility model, but the scope of protection of the utility model is not limited thereto. The equivalent replacement or change of the new technical solution and the concept of the utility model shall be covered by the protection scope of the utility model.
