A plurality of screening plates are arranged side by side and are independent of each other, and a screening movement occurs forward and backward and up and down when driven by the crank transmission assembly, and some screening plates move forward while some screen plates move backward. The visual inspection mechanism is selected as an industrial camera, which is connected to the control terminal, which can be a computer. The visual inspection mechanism takes real-time images of the screening plate and transmits them to the control terminal. The staff only needs to check them at the control terminal. In addition, the built-in automatic judgment application, that is, the image comparison method, can be used for automatic monitoring.

[0029] The support frame 6 is provided with a fan 8, which blows air along the length direction of the screen plate 1. Two fans 8 are provided, which are respectively located on both sides of the support frame. The screening frame is usually set at an angle, that is, one side is high and the other side is low. The fan blows air from low to high, which is convenient for blowing lighter materials upward, playing a role of auxiliary feeding.

[0030] The control terminal is connected to an alarm. By setting an automatic image comparison application on the control terminal, when the image obtained by the visual detection mechanism is compared with the preset image, if it is determined that the material residue has exceeded the preset value, the alarm will sound. The alarm can be a sound alarm or an indicator light to remind the staff so that they can deal with it in time to ensure the continuous screening process.

[0031] Embodiment 2

The screening plate keeps a synchronous tilting state with the screening frame in the screening frame, the first solid section is at the lowest point, the second filter hole section is in the middle, and the third solid section is at the highest point. The material is generally poured from the lowest point of the screening plate, and then passed upward through the front and rear screening movement of the screening plate. The retaining wall can prevent the material from randomly moving to other screening plates. The filter hole can be a circular hole, a square hole, or other types of holes.

[0033] The crank transmission assembly 5 includes a rotating shaft 51 and a plurality of eccentric wheels 52 with different eccentric positions. Both ends of the rotating shaft 51 are mounted on the side wall of the screening frame 1 through bearings. One end of the rotating shaft 41 is connected to the driving shaft of the driving motor 3. A plurality of eccentric wheels 52 are fixedly mounted on the rotating shaft 41, and the screening plate 4 is connected to the eccentric wheels 52. A crank transmission assembly 5 is provided on each side of the screening frame 1. A screening plate 4 usually needs to be equipped with at least two eccentric wheels with the same eccentric position to ensure smoother movement. Two adjacent screening plates are equipped with eccentric wheels with different eccentric positions, so as to ensure the front-to-back staggered movement of the two adjacent screening plates, and realize the screening movement of one front-to-back and one up-and-down.

[0034] Embodiment 3

[0035] refer to Figure 1-4 As shown, a cavity is provided inside the eccentric wheel, and cooling oil is filled in the cavity to play a cooling and lubricating role, cooling oil or thin oil, lubricating oil. A filling port and an oil discharge port can be provided on the side wall of the eccentric wheel, and the filling port and the oil discharge port need to be sealed when not in use. Cooling oil is filled into the cavity inside the eccentric wheel. This structure needs to replace the cooling oil after a period of use. Alternatively, another solution is adopted, where a circulating hose is connected to the filling port and the oil discharge port, and connected to the oil supply device to form a continuous flow of cooling oil.

[0036] The base 2 is provided with a bearing seat, through which the rotating shaft passes. The bearing seat is generally arranged at the middle position of the rotating shaft to ensure that the rotating shaft remains stable during rotation.

[0037] The angle adjustment mechanism can be used to adjust the inclination angle of the base. Since the screening frame is installed on the base, the screening frame and the screening plate also maintain synchronous inclination. It can usually be adjusted within the range of 0-30 degrees to meet the screening of various materials. The angle adjustment mechanism includes a fixed plate and a hydraulic cylinder. One side of the fixed plate is hingedly mounted with the base, and the hydraulic cylinder is mounted on the fixed plate. The driving rod of the hydraulic cylinder is hingedly mounted with the base. The hydraulic cylinder can be used to easily lift the base and the screening frame to achieve automatic adjustment.

[0038] Or the angle adjustment mechanism includes an upper vertical plate 9 and a lower vertical plate 10, the upper end of the upper vertical plate 9 is connected to the base 2, and the lower part of the upper vertical plate 9 and the upper part of the lower vertical plate 10 are respectively provided with a plurality of screw holes, and the lower part of the upper vertical plate 9 and the upper part of the lower vertical plate 10 are locked and connected by screws passing through the screw holes. The upper vertical plate is installed on the side corresponding to the third solid section of the screening plate, and the other side of the base is assembled in a lower position to achieve the tilted posture of the base and the screening frame. The assembly position of the upper vertical plate and the lower vertical plate can be adjusted to achieve height adjustment. This adjustment method requires manual adjustment, which is a manual operation method compared to the automatic adjustment method of the hydraulic cylinder, which is more labor-intensive, but it can also achieve the adjustment purpose.

[0039] In addition, the support frame 6 is provided with a tool rack 11, and the tool rack 11 is provided with a plurality of clamping holes, in which a cleaning rod 12 is inserted, and the cleaning rod is a horizontal section and a bending section including an integral structure, and the horizontal section is clamped into the clamping hole. Since the second filter hole section of the screening plate is a filter hole, sometimes there is a situation that the material is stuck in the filter hole, thereby affecting the screening efficiency. When the material residue is blocked, the cleaning rod can be removed for cleaning, and there is no need to find a cleaning tool separately, thereby improving the cleaning efficiency.

[0040] In the utility model, the inclination angle of the screening frame is set to 15 degrees, the first solid section on the screening plate is at the lowest position, the third solid section is at the highest position, and it is installed in coordination with the external motion device, and the lower bin faces the lowest part of the screening plate, that is, the first solid section area. The bottom of the screening frame cooperates with the motion mechanism, and needs to face the first solid section, the second filter hole section and the third solid section of the screening plate, and connect different motion mechanisms respectively.

[0041] It can be used to screen the rolling 3D material part and the light, flat 2D material part and the undersize material part.

[0042] 3D materials include: stones, wood, boxes, bottles, etc.; light, flat 2D materials include: plastic films, packaging bags, cartons, fiber products and other light materials; under-screen materials include: fine materials, sand, organic matter, etc. It can be used to screen heavier materials, thereby achieving a heavy load effect.

[0043] The material is unloaded from the first solid section of the screening plate, and the shaft is driven to rotate by the driving motor. The eccentric movement of the eccentric wheel drives each screening plate to perform screening movement forward, backward, and upward, which also causes the material that falls on the screening plate to be thrown forward and upward continuously and in a jumping manner. The amplitude of the material throwing up and the speed of the forward movement are determined by the speed and eccentricity of the driving motor. In the process of the material being thrown up and forward and then falling down, the heavier 3D material falls down from the gap between the first solid section and the screening frame; the under-screen material is transported to the second filter hole section and falls from the filter hole; the light, flat 2D material continues to be transported upward, and is pushed with the help of the fan, and finally falls from the port of the third solid section. During the movement, each screening plate moves up and down, forward and backward, and a height difference is formed between each two screening plates, which facilitates the separation of materials, so as to separate the solids and improve the screening efficiency.

[0044] In addition, by utilizing the real-time detection of the visual detection mechanism, when the filter hole is found to be blocked, it can be cleaned in time, and there is no need to carry additional tools. The cleaning rod can be directly taken out from the support frame for cleaning, thereby improving efficiency.

[0045] It should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein. However, any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
