The screen includes a main body with symmetrically slidable sliders at its top, a splash-proof baffle, and the bottom end of the splash-proof baffle fixedly connected to the slider. Both sides of the main body have fixing mechanisms for locking the slider. Each fixing mechanism includes multiple support frames, with a limiting block slidably disposed inside for limiting the slider's connection. One side of the limiting block is fixedly connected to a fixing rod for connection operation, a sliding plate, and multiple springs. This invention utilizes the cooperation of the splash-proof baffle, slider, support frames, limiting blocks, sliding plates, fixing rods, and springs. The sliding plate drives two fixing rods in the same row to move, and the limiting blocks limit and release the relative position of the vibrating screen main body and the slider, thus facilitating the installation and disassembly of the slider and the splash-proof baffle, making maintenance easier and operation more convenient.

[0003] Based on the above, the inventors have discovered the following problems: the above device can effectively prevent splashing and the splash guard can be easily disassembled and installed, but it ignores the situation where items on the screen collide with the splash guard and cause damage, especially items with low hardness such as corn and sunflower seeds.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 The present invention provides a technical solution as follows:

[0021] Example:

[0022] In this embodiment, a vibrating screen with a splash-proof structure includes a baffle 1 and a support frame 5. The upper end of the support frame 5 is provided with a screen 14, and the upper end of the screen 14 is provided with a baffle 1. A feed inlet 4 is provided on one side of the baffle 1, and a discharge outlet 3 is provided on the side of the baffle 1 away from the feed inlet 4. A pair of limiting members 6 are provided on the side of the baffle 1 that is not at the discharge outlet 3 and the feed inlet 4. The limiting members 6 are movably mounted on the support frame 5, and the baffle 1 is provided with an anti-collision component. A support plate 7 is provided on one side of the support frame 5, and a rotating motor 8 is provided on the upper end of the support plate 7. A connecting shaft 19 is provided at the output end of the rotating motor 8. The connecting shaft 19 is movably mounted on the upper end of the support frame 5 through a bearing, and the connecting shaft 19 is located below the screen 14. A protrusion 20 is provided in the middle of the connecting shaft 19, and the top end of the protrusion 20 is attached to the lower end of the screen 14.

[0023] The rotation of the motor 8 drives the connecting shaft 19 to rotate synchronously, which in turn drives the protrusion 20 on the connecting shaft 19 to rotate, thereby causing the screen 14 to vibrate. When the larger diameter end of the protrusion 20 is flush with the lower end of the screen 14, the screen 14 falls to the lowest point of vibration under its own weight, where it is in contact with the protrusion 20. When the smaller diameter end of the protrusion 20 is in contact with the bottom of the screen 14, the screen 14 is pushed by the protrusion 20 to the highest point of vibration. Through the rotation of the protrusion 20, the screen 14 and the baffle 1 on it can vibrate synchronously.

[0024] The anti-collision assembly includes an air duct 10, a belt drive assembly 9 on the side of the connecting shaft 19 near the rotating motor 8, a rotating shaft 12 connected to the belt drive assembly 9, a connecting seat 11 connected to the rotating shaft 12 via another bearing, the connecting seat 11 being located on the upper end of the support plate 7, an air duct 10 on the side of the baffle 1, a fan 17 being installed in the air duct 10 at the end of the rotating shaft 12 away from the connecting seat 11, a chamber being provided in the baffle 1, a breathable plate 15 being provided on the side of the chamber facing the screen 14, and the chamber being connected to one end of the air duct 10.

[0025] The part of the air guide pipe 10 that is not baffle 1 and the shaft 12 is made of elastic and stretchable material, so that when the baffle 1 and the screen 14 vibrate, it will not affect the operation of the anti-collision component.

[0026] The rotation of the shaft 12 drives the fan 17 to rotate, and the output direction of the fan 17 is towards the air guide tube 10. Thus, the rotation of the fan 17 can blow air into the air guide tube 10. With the cooperation of the air guide tube 10, the airflow is transmitted to the chamber in the baffle 1. With the design of the permeable plate 15, airflow can be generated on the surface of the permeable plate 15. Thus, when the device performs vibration screening, the screened items will splash with the vibration. Under the action of the baffle 1, the items will not splash out of the device, thereby avoiding raw material loss and pollution of the work site during the screening operation. When the splashed items are about to come into contact with the permeable plate 15 in the baffle 1, the airflow through the permeable plate 15 can disperse and consume the force of the movement of the items, reducing the probability of collision between the screened items and the permeable plate 15, avoiding damage to the permeable plate 15 and damage to the screened items due to collision, improving the service life of the device and the integrity of the screened items.

[0027] The connection between the chamber and the air guide tube 10 is located at the center of the upper end of the baffle 1. Several connecting posts 18 are provided at the connection between the chamber and the air guide tube 10. One end of the connecting post 18 is connected to the inner wall of the air guide tube 10, and the other end of the connecting post 18 is connected to the air guide plate 16.

[0028] By designing the air guide plate 16, the airflow in the air guide pipe 10 can be evenly guided to the side of the inner cavity of the baffle 1. This ensures that the airflow intensity of the side vents at the same horizontal level of the air vent plate 15 remains the same. As a result, the airflow intensity is lower when the air vent plate 15 is close to the screen 14, and higher when the air vent plate 15 is far from the screen 14. This prevents the airflow from the air vent plate 15 from affecting the vibration operation of the items being screened on the screen 14, and also avoids collisions between the items being screened and the air vent plate 15, making this equipment highly practical.

[0029] The belt drive assembly 9 includes a pair of drive wheels and a drive belt. The pair of drive wheels are respectively connected to the connecting shaft 19 and the rotating shaft 12. The drive belt is sleeved on the pair of drive wheels, and the diameter of the drive wheel on the connecting shaft 19 is smaller than the diameter of the drive wheel on the rotating shaft 12.

[0030] By designing the belt drive assembly 9, the power of the rotating motor 8 can drive the anti-collision components and the vibration operation of this device simultaneously, which can improve resource utilization, reduce energy consumption, and greatly reduce usage and production costs.

[0031] The airflow on the ventilation plate can be adjusted by the diameter ratio between a pair of drive wheels in the belt drive assembly 9, and can be adjusted accordingly based on the type of items being screened.

[0032] The ventilation holes on the ventilation plate 15 are evenly distributed, and the diameter of the ventilation holes on the ventilation plate 15 is smaller than the mesh diameter of the screen 14.

[0033] Since the diameter of the air holes on the air permeable plate 15 is much smaller than the diameter of the mesh of the screen 14, and the air holes on the air permeable plate 15 are used for airflow transmission, the situation of the screened items getting stuck on the surface of the air permeable plate 15 is avoided.

[0034] The screen 14 is provided with a receiving frame 13 at its lower vertical position.

[0035] The lower end of the discharge port 3 is provided with a receiving frame 2.

[0036] Working principle:

[0037] First, the rotating motor 8 is started, driving the connecting shaft 19 to rotate synchronously. This causes the protrusion 20 on the connecting shaft 19 to rotate, thus vibrating the screen 14. When the larger diameter end of the protrusion 20 is flush with the lower end face of the screen 14, the screen 14 falls under its own weight to be in contact with the protrusion 20 and at the lowest point of vibration. When the smaller diameter end of the protrusion 20 is in contact with the bottom of the screen 14, the screen 14 is pushed by the protrusion 20 to the highest point of vibration. Through the rotation of the protrusion 20, the screen 14 and the baffle 1 above it can be vibrated synchronously. Through the design of the belt drive assembly 9, the rotating shaft 12 can be driven to rotate, causing the fan 17 to rotate. The output direction of the fan 17 is towards the air guide pipe 10, so the rotation of the fan 17 can... Air is blown into the air duct 10. With the cooperation of the air duct 10, the airflow is transmitted to the chamber in the baffle 1. With the design of the permeable plate 15, airflow can be generated on the surface of the permeable plate 15. Thus, when the device performs vibration screening, the screened items will splash with the vibration. Under the action of the baffle 1, the items will not splash out of the device, thereby avoiding raw material loss and pollution of the work site during the screening operation. When the splashed items are about to come into contact with the permeable plate 15 in the baffle 1, the airflow through the permeable plate 15 can disperse and consume the force of the movement of the items, reducing the probability of collision between the screened items and the permeable plate 15, avoiding damage to the permeable plate 15 and damage to the screened items due to collision, improving the service life of the device and the integrity of the screened items.
