[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] The utility model provides Figure 1-3 A vibrating screen box for continuously processing viscous materials is shown, comprising a screening box 1, wherein a screening assembly for material screening is arranged inside the screening box 1, and the screening assembly comprises a screening rod 6, and a plug hole 3 for inserting the screening rod 6 is opened on the front side of the screening box 1, and a screening outlet 2 for discharging bulk materials is opened on the back side of the screening box 1, and a limit plate 7 for limiting the movement of the screening rod 6 is arranged at one end of the screening rod 6.

[0018] Specifically, a screening trough 8 for material screening is provided at the top of the screening box 1, and a support plate 5 for enhancing the supporting force of the middle part of the screening rod 6 is provided inside the screening trough 8, and both ends of the support plate 5 are fixedly connected to the two sides of the inner wall of the screening trough 8 respectively.

[0019] Furthermore, the screening trough 8 passes through the screening box 1. When the screening box 1 is placed, the end of the screening box 1 where the insertion hole 3 is provided is placed higher than the end where the screening outlet 2 is provided. The support plate 5 is arranged in the middle of the screening box 1 to support the screen rod 6 in the middle of a section of the screening trough 8. When the material falls, the impact resistance of the screen rod 6 is enhanced, making the screen rod 6 more durable. The support plate 5 is made of the same material as the screening box 1.

[0020] Specifically, the inner wall of the screening trough 8 is fixedly connected with a guide block 4 for guiding materials. The guide block 4 is arranged on the side of the inner wall of the screening trough 8 close to the screening outlet 2. The vertical cross-section of the screening outlet 2 is U-shaped, and the transverse cross-section of the guide block 4 is triangular. The back side of the limit plate 7 is fixedly connected to the front side of the screen rod 6, and the vertical cross-sections of the jack 3 and the screen rod 6 are both circular.

[0021] Furthermore, the size of the jack 3 is 1.02 times the size of the screen rod 6, the center of the jack 3 is in the same straight line as the center of the arc at the bottom of the screening outlet 2, multiple groups of screening components are arranged, each group of screening components corresponds to a screening outlet 2 and a jack 3, the guide block 4 is a triangular prism, the guide block 4 is arranged between adjacent screening outlets 2, the inclined surface of the guide block 4 can play a role in guiding and diverting, guiding large pieces of material to the position of the screening outlet 2, and not generating accumulation inside the screening slot 8, the guide block 4 is close to the side of the screening slot 8, through welding The screen outlet 2 is fixedly connected to the inner wall of the screen slot 8 in a fixed manner, and the top of the screen outlet 2 passes through the top of the screen box 1, which is conducive to the discharge of materials. The size of the limit plate 7 is 1.2 times the size of the plug hole 3. The back of the limit plate 7 and the front of the screen rod 6 are fixedly connected by welding. The screen rod 3 is set in the middle of the limit plate 7. The screen rod 3 and the screen box 1 are both made of stainless steel. The length of the screen rod 6 is 5-10 cm longer than that of the screen box 1, so as to prevent the screen rod 6 from being set at one side of the screen outlet 2 when the screen rod 6 vibrates. The end of the screen falls into the screen drop slot 8. The number of the plurality of screen rods 6 is selected according to the size of the particles of the screened material. Through the setting of the plurality of screen outlets 2 and the plug holes 3, the plurality of screen rods 6 are inserted into the screen outlets 2 and the plug holes 3 one by one. The plurality of screen rods 6 are placed side by side in the screen box 1 to form a screen surface. The screen box 1 is fixed on the vibrating screen according to the slope requirements of the vibrating screen. Then, when the vibrating screen is turned on, the material falls on the vibrating screen surface. The fine material passes through the gaps between the screen rods 6, and the large block material that cannot pass through the gaps is generated by the vibrating machine. Under the action of high-frequency vibration force, the material moves toward the screening outlet 2 along the slope set by the screening box 1 for discharge, which solves the problem of material blockage. At the same time, there is no firm connection between the screen rod 6 and the screening box 1. Therefore, when working, the screen rod 6 will vibrate while vibrating with the vibrating screen, thereby avoiding the problem of sticky materials on the screen rod 6. The screen rod 6 is installed independently. When the screen rod 6 is damaged, there is no need to stop the machine. The damaged screen rod 6 can be directly pulled out and a new screen rod 6 can be reinstalled. This solves the impact of stopping the machine on production and ensures continuous production.
