[0003] When screening fine-grained materials or difficult-to-screen materials, due to their high viscosity, they are usually screened in a manner that increases their residence time on the screen. For example, Chinese patent application number 202320059469.7 discloses a vibrating screen with an adjustable screen angle, the structure of which includes a vibrating box, a screen body, and a mounting frame that can slide along the inner wall of the vibrating box is fixedly sleeved outside the screen body; a follower block is fixedly arranged on one side of the mounting frame, and a first slide groove is provided on the vibrating box for the follower block to slide along the depth direction of the vibrating box, and a moving block is connected to the follower block; a moving assembly is arranged outside the vibrating box, and the moving assembly can drive the moving block to rise and fall; a rotating rod rotatably connected to the vibrating box is penetrated on the side of the mounting frame away from the follower block, and when the moving block rises and falls, the rotating rod rotates accordingly. The vibrating screen with adjustable screen angle increases the residence time of the material on the screen by adjusting the screen angle, but the residence time that can be extended by this method is limited. At most, the screen can be leveled so that the material moves on the horizontal screen. Moreover, the material moves in a straight line on the screen, which will cause a small contact area between some materials and the screen, thus affecting the screening quality.

The extension plate 109 is located above the screen plate 101, and the baffle 110 at the bottom is in contact with the screen plate 101. One side of the rotating block 107 is provided with a tooth surface 108 meshed with the worm 106, and the other side of the rotating block 107 is provided with an extension plate 109 extending to the screen plate 101. When the material moves along the baffle 110, it will be guided to another baffle 110 by the previous baffle 110, thereby increasing the distance the material moves on the screen plate 101, and at the same time, the number of baffles 110 can be increased to prolong the residence time of the material on the screen plate 101. The bottom of the extension plate 109 is connected with a baffle 110 in contact with the screen plate 101;
[0030] refer to Figure 5 and Figure 6 A vibrating screen device 111 is arranged outside the screen frame 102. The vibrating screen device 111 is a vibrating screening device, which is a mature device and will not be described in detail here. A discharge pipe 112 is arranged on one side of the vibrating screen device 111. The top of one end of the vibrating screen device 111 is a feed port, and the other end is connected to different discharge pipes 112. The screened materials are discharged through different discharge pipes 112. The rotating rod 105 extends out of the vibrating screen device 111 at one end away from the discharge pipe 112, and a rotating handle 113 is connected to it.
[0031] refer to Figure 2 and Figure 5, a worm wheel 114 is connected to the outer wall of one of the rotating rods 105 through a worm 106, a connecting rod extending from the vibrating screen device 111 is connected to the inside of the worm wheel 114, and an indicating disk 115 is connected to one end of the connecting rod outside the vibrating screen device 111. When the rotating rod 105 rotates, the indicating disk 115 is driven to rotate through the worm wheel 114, and the indicating disk 115 will indicate the corresponding position of the dial 116. The scale on the dial 116 can be set to the angle of the baffle 110, or the time that the material stays on the screen plate 101. The outer wall of the vibrating screen device 111 is connected to a dial 116 corresponding to the indicating disk 115;
[0032] refer to Figure 2 A synchronization component 117 is connected to one side of the rotating rod 105 close to the rotating handle 113. By rotating one rotating rod 105, the synchronization component 117 can drive the other rotating rod 105 to rotate, and the synchronization component 117 passes through the hollow connecting frame 103.
[0033] Specifically, refer to Figure 4 A spline portion 118 is provided at one end of the rotating rod 105 close to the rotating handle 113. The rotating handle 113 slides back and forth on the spline portion 118 to drive the rotating rod 105 to rotate. The rotating handle 113 is slidably connected on the spline portion 118. A fixing sleeve 119 fixed to the vibrating screen device 111 is provided on the outside of the spline portion 118. The fixing sleeve 119 is fixed on the outer wall of the vibrating screen device 111 to fix the rotating handle 113 and the spline block 120. One end of the rotating handle 113 is connected to the spline block 120 spline-connected to the fixing sleeve 119.
[0034] Specifically, refer to Figure 4 The end of the spline portion 118 away from the rotating rod 105 is connected to a limit plate 121, and the limit plate 121 is used to support one end of the spring 122. At the same time, it can prevent the rotating handle 113 from detaching from the spline portion 118. A spring 122 is arranged between the limit plate 121 and the rotating handle 113.
[0035] Specifically, the synchronization assembly 117 is composed of a sprocket and a chain, and the synchronization assembly 117 is used to keep the two rotating rods 105 rotating synchronously.
[0036] Specifically, refer to Figure 1 The extension plates 109 on both sides of the screen plate 101 are arranged alternately, so that after the material leaves one baffle plate 110, it will move to another baffle plate 110.
[0037] In this embodiment, the screen plate 101 is fixed on the screen frame 102, and the screen frame 102 is installed on the inner wall of the vibrating screen device 111. When in use, the material is added into the vibrating screen device 111 through the filling port at the top. A vibration motor is arranged on the vibrating screen device 111 to drive the vibrating screen device 111 to vibrate. When the material enters the vibrating screen device 111, it falls on the end of the screen plate 101 away from the discharge pipe 112. The material moves toward one end of the discharge pipe 112 through vibration, and the screened material is discharged through different discharge pipes 112.
[0038] A plurality of baffles 110 are arranged on the screen plate 101. By adjusting the angle of the baffles 110 on the screen plate 101, the residence time of the material on the screen plate 101 is increased. When the material moves, it moves from one baffle 110 to another baffle 110. With the blocking of the plurality of baffles 110, the residence time of the material is increased, so as to enhance the screening effect of the viscous material.
[0039] When the angle of the baffle 110 needs to be adjusted, the rotating handle 113 is pulled outward so that the spline block 120 on the other side of the rotating handle 113 is pulled out of the fixed sleeve 119, and the fixed sleeve 119 loses its restrictive effect on the spline block 120. At this time, the rotating handle 113 is rotated, and the rotating handle 113 is connected with the spline portion 118 through the spline, thereby driving the rotating rod 105 to rotate synchronously. The rotating rod 105 drives the rotating block 107 to rotate through the multiple worms 106 on the outer wall. When the rotating block 107 rotates, the baffle 110 is driven to rotate on the screen plate 101 through the extension plate 109 on the outer wall, so as to adjust the angle of the baffle 110. At the same time, the rotating rod 105 will also drive the indicator disk 115 to rotate through the worm gear 114. The indicator disk 115 is used to display the current angle of the baffle 110 or the residence time of the material on the screen plate 101.
[0040] After the angle of the baffle 110 is adjusted, the spring 122 will push the rotating handle 113 and the spline block 120 to move toward the fixed sleeve 119, so that the spline block 120 will be inserted into the fixed sleeve 119. The fixed sleeve 119 restricts the rotating handle 113 through the spline connection with the spline block 120, thereby preventing the rotating rod 105 from rotating when the vibrating screen device 111 vibrates.
[0041] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
