[0029] During operation, sand is poured into the storage box 101 through tools such as a forklift. According to the quality of the sand, the docking piece 4 is operated to connect with the corresponding number of discharge pieces 2, and driven by the docking piece 4, the discharge piece 2 is rotated to complete the quantitative discharge, thereby ensuring that the vibrating screen can complete the screening operation of the sand and avoid accumulation that causes a decrease in filtration quality. The overall structural design is ingenious and meets the use requirements in different situations. Among them, the inner wall of the discharge port of the storage box 101 is a circular inner wall, which is adapted to the structure of the discharge piece 2.

[0030] A preferred embodiment, combined with Figure 5 As shown, a plurality of volume spaces 201 are provided along the circumferential direction of the discharge piece 2, and each rotation drives a corresponding amount of sand to be discharged. At the same time, a docking hole 202 is provided in the middle of the side of the discharge piece 2 for insertion and connection of the docking piece 4.

[0031] A preferred embodiment, combined with Figure 2 and Figure 3 As shown, a support shaft 102 which is sleeved with the discharge piece 2 is provided at the discharge port of the material storage box 101, one end of the support shaft 102 is fixedly connected to the material storage box 101, and the other end is sleeved with the receiving plate 301. The center of the discharge piece 2 has a through hole which is sleeved with the support shaft 102, which can improve the stability of the discharge piece 2 after installation and improve the carrying capacity.

[0032] A preferred embodiment, combined with Figure 7 As shown, a plurality of friction strips 203 in contact with the support shaft 102 are provided at the center of the discharge piece 2. The friction strips 203 are made of rubber material and rely on the elastic force of the friction strips 203 themselves to maintain close contact with the support shaft 102 and rely on friction force to assist in positioning. When the docking rod 601 is connected and rotated with one of the discharge pieces 2, it avoids causing the remaining discharge pieces 2 to rotate out of position and cause leakage.

[0033] A preferred embodiment, combined with Figure 4-6 As shown, the docking member 4 includes a motor 5 and a turntable 6; the motor 5 is fixedly connected to the front of the bracket 3 by screws, and a power shaft 501 is provided on the shaft of the motor 5, and a rectangular slide groove (similar to a spline groove structure) is distributed on the surface of the power shaft 501; the center of the turntable 6 is connected to the power shaft 501 and can slide along the power shaft 501, and a plurality of docking rods 601 are provided on the turntable 6; the motor 5 drives the turntable 6 to rotate through the power shaft 501, and during the rotation, the turntable 6 can be axially displaced along the power shaft 501, so that the docking rod 601 penetrates into the docking hole 202 of the discharge piece 2 to form a circumferential positioning, and the function of quantitative discharge can be realized by controlling the docking rod 601 to penetrate into different numbers of discharge pieces 2.

[0034] A preferred embodiment, combined with Figure 4 and Figure 5 As shown, a receiving plate 301 is provided at the rear of the bracket 3, and a supporting hole corresponding to the position of the docking hole 202 is processed on the receiving plate 301. At the same time, a bearing hole is provided at the center of the receiving plate 301, and the supporting hole is slidably connected to the docking rod 601 to realize its supporting positioning without affecting its sliding, and the bearing hole in the center is respectively sleeved with the end portions of the power shaft 501 and the support shaft 102, playing a supporting role without affecting the rotation of the power shaft 501.

[0035] A preferred embodiment, combined with Figure 4 and Figure 5 As shown, a hydraulic cylinder 302 is provided in front of the bracket 3, and a mounting plate 303 is provided on the push rod of the hydraulic cylinder 302. The mounting plate 303 is rotatably connected to the turntable 6. The hydraulic cylinder 302 pushes the mounting plate 303 to move, thereby driving the docking rod 601 to move.

[0036] A preferred embodiment, combined with Figure 5 and Figure 6As shown, in order to improve the reliability of the docking process between the docking rod 601 and the discharge piece 2, two cylindrical rods are welded on the right side of the turntable 6, and a pressure plate 602 is sleeved on the cylindrical rod to form a sliding connection. At the same time, a supporting spring 603 is sleeved on the cylindrical rod. The right side of the supporting spring 603 contacts the pressure plate 602 to support and position the pressure plate 602, and the pressure plate 602 is rotatably connected to the mounting plate 303, and the turntable 6 itself is no longer connected to the mounting plate 303. During the docking process, since the docking rod 601 is in a rotating state, when it contacts the side of the discharge piece 2, it may not be directly inserted into the docking hole 202. Therefore, as the hydraulic cylinder 302 continues to push, the supporting spring 603 is compressed, and after the docking rod 601 rotates to a suitable position, it penetrates under the elastic force of the supporting spring 603, providing a reserved displacement space to facilitate the docking operation.

[0037] A preferred embodiment, combined with Figure 3-5 As shown, guide rods 304 connected to the mounting plate 303 are provided on both sides of the bracket 3. The guide rods 304 and the mounting plate 303 are slidably connected to support and guide the mounting plate 303, thereby improving the stability of the mounting plate 303 during displacement.

[0038] It should be understood that the above specific embodiments of the present invention are only used to illustrate or explain the principles of the present invention, and do not constitute a limitation of the present invention. Therefore, any modification, equivalent replacement, improvement, etc. made without departing from the spirit and scope of the present invention should be included in the protection scope of the present invention.
