Description

A sand and gravel separator with rotating and vibrating screen

technical field

The utility model relates to the field of sand and gravel sorting equipment, in particular to a sand and gravel sorting machine with a rotating and vibrating screen.

Background technique

With the rapid development of the construction industry, the demand for sand and gravel is increasing. Sand and gravel sorting is an important process in the sand and gravel manufacturing industry, but there are many shortcomings in the current common sand and gravel sorting machines: some screening The effective area is small, and the screening efficiency is low; some cannot be automatically discharged, and cannot be continuously operated; some have complex mechanisms and high failure rates; some use manual screening, which has high work intensity and low screening efficiency, which cannot meet the requirements of modern people. .

Contents of the invention

The purpose of the utility model is to provide a sand and stone sorting machine with a rotating and vibrating screen for the problems of low screening efficiency and poor quality performance of sand screening equipment in the existing artificial sand and gravel sorting process.

The utility model is a sand and gravel sorting machine for rotating and vibrating screens, comprising a frame, a screen, a drive shaft, a first pulley, a belt, a second pulley, a motor, an exciting device, a spring, an extension rod, and a baffle . The screen is connected to the middle end of the drive shaft through a fixing mechanism, the other end of the drive shaft is connected to the vibrator, the drive shaft is connected to the frame through a bracket, and the first pulley is connected to the frame through a key. It is connected with one end of the drive shaft, the second pulley is connected with the motor through a key, the second pulley is connected with the first pulley through the belt, one end of the spring is connected with the frame, and the other One end is connected with the screen, the extension rod is connected with the drive shaft, the baffle is located below the drive shaft, and the baffle is connected with the frame.

Further, the screens are rectangular, and the screens are symmetrically distributed on both sides of the drive shaft.

Further, the number of springs is K, where K is an integer greater than or equal to 1.

The utility model has the beneficial effects of simple structure, low cost, easy processing and maintenance, automatic material discharge and high screening efficiency.

detailed description

Below, with reference to the accompanying drawings, the utility model is described more fully, and exemplary embodiments of the utility model are shown in the accompanying drawings. However, the invention may be embodied in many different forms and should not be construed as limited to the exemplary embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

The utility model relates to a sand and gravel sorting machine with a rotating and vibrating screen, as shown in Figure 1, including a frame 1, a screen 2, a drive shaft 3, a first pulley 4, a belt 5, and a second pulley 6 , motor 7, excitation device 8, spring 9, extension rod 10, baffle plate 11; described motor 7 provides power, and described second pulley 6 is connected with described motor 7 by key, and described second pulley 6 passes through The belt 5 is connected with the first pulley 4, the first pulley 4 is connected with the drive shaft 3 through a key for power transmission, the drive shaft 3 is connected with the frame 1 through a fixing mechanism, and the drive shaft 3 is connected with the frame 1 through a fixing mechanism. The middle end of the shaft 3 is connected to the screen 2, and the vibration excitation device 8 is connected to the other end of the drive shaft 3. The vibration excitation 8 is used to provide axial vibration to the screen 2. The extension The rod 10 is connected to the drive shaft 3, the drive plate 11 is located below the drive shaft 3, the extension rod 10 is in intermittent contact with the baffle plate 11, so that the rotatable angle of the drive shaft 3 is less than 180 degrees, One end of the spring 9 is connected to the frame 1, and the other end is connected to the screen 2. The motor 7 rotates forward intermittently. After the screen 2 is placed flat for a period of time, the motor 7 For a certain period of time, the screen 2 rotates forward for a certain angle, the motor 7 stops working, the screen 2 reverses under the action of the spring 9, and the extension rod 10 contacts the stopper 11 , the sieve 2 is placed horizontally and the reverse rotation is stopped, and the above-mentioned actions are repeated to complete the screening and automatic discharge of sand and gravel.
