[0023] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation methods in conjunction with the accompanying drawings.

[0024] Please refer to Figures 1 to 4As shown, a mortar raw material vibration screening device of the present invention includes a base 1, a frame 2 is rotatably connected to the base 1, two electric push rods 3 are hinged on the outside of the frame 2 through a pin shaft, and a support column 4 is connected to the electric push rod 3. A screen 5 is provided in the frame 2, and a discharge pipe 6 is connected under the screen 5. The front of the frame 2 is connected to a pushing device 7, and an auxiliary device 8 is provided in the pushing device 7. The back of the frame 2 is connected to a vibration motor 9, and the pushing device 7 includes a stepping motor 71. One side of the stepping motor 71 is connected to a reciprocating screw rod 72, and one side of the reciprocating screw rod 72 is rotatably connected to a mounting plate 74. The mounting plate 74 is connected to the front of the frame 2. The reciprocating screw rod 72 is outer-circuited with a threaded cap 73, and a connecting rod 75 is connected to the threaded cap 73. The back of the connecting rod 75 is connected to a baffle 76, which is overlapped on the screen 5. The back of the baffle 76 is connected to a long rod 77, and the long rod 77 is slidably connected to a fixing plate 78. In the actual implementation process, when the mortar needs to be screened, the mortar is poured into one side of the baffle 76, and then the vibration motor 9 and the stepper motor 71 are started. The vibration motor 9 drives the frame 2 and the screen 5 to shake, and at the same time the stepper motor 71 drives the reciprocating screw 72 to rotate, the reciprocating screw 72 drives the threaded cap 73 to move, the threaded cap 73 drives the connecting rod 75 to move, and the connecting rod 75 drives the baffle 76 to move. The baffle 76 slides on the screen 5 at a uniform speed. At this time, the baffle 76 drives the long rod 77 to slide in the fixed plate 78, thereby completing the uniform screening of the mortar, avoiding the problem that when the material is put on the screen 5, the upper screen 5 may fail to complete the screening process in time and start to roll down, which may cause smaller materials to be filtered out in the coarser part of the screen 5, thereby affecting the thoroughness of the screening.

[0025] Optionally, the stepper motor 71 is connected to the front of the frame 2, and the threaded cap 73 is overlapped on the front of the mounting plate 74. In actual implementation, by setting up the stepper motor 71 and the reciprocating screw 72, the stepper motor 71 cooperates with the reciprocating screw 72 to achieve precise position control and stepping motion. It is widely used in fields such as CNC machinery, automated assembly lines, and precision positioning devices. The stepper motor 71 has high positioning accuracy, adjustable speed and acceleration, and other flexibility, making it an ideal choice for achieving precise and efficient linear motion, so that the movement of the baffle 76 can be precisely controlled.

[0026] Optionally, the baffle 76 is slidably connected to the frame 2, and the fixing plate 78 is connected to the back of the frame 2. In actual implementation, by setting the baffle 76 and the frame 2, the baffle 76 cooperates with the frame 2, so that the frame 2 limits the baffle 76, so that it remains stable during the sliding process.

[0027] Optionally, the auxiliary device 8 includes two fixed blocks 81, which are connected to one side of the baffle 76. One side of the fixed block 81 is connected to a drive motor 82, and the output end of the drive motor 82 is connected to a cam 83, and the outside of the cam 83 is overlapped with an extrusion block 84. In actual implementation, when screening, the drive motor 82 is started, and the drive motor 82 drives the cam 83 to rotate. The cam 83 intermittently squeezes the extrusion block 84, and the extrusion force drives the extrusion block 84 to move. At this time, the extrusion block 84 drives the slide bar 85 to move. Then, when the cam 83 moves away from the extrusion block 84, the return spring 86 applies elastic force to the extrusion block 84, and the elastic force drives the extrusion block 84 to move, so that it can be quickly reset, thereby achieving the slide bar 85 can reciprocatingly squeeze the material on one side of the baffle 76 during the screening process, so that the material can be more evenly screened.

[0028] Optionally, a slide bar 85 is connected to one side of the extrusion block 84, and a pull-back spring 86 is provided on the outer sleeve of the slide bar 85. In actual implementation, by setting the extrusion block 84 to cooperate with the slide bar 85, the extrusion block 84 cooperates with the slide bar 85, so that when the extrusion block 84 is subjected to the extrusion force, it will drive the slide bar 85 to move synchronously.

[0029] Optionally, one end of the return spring 86 is connected to one side of the extrusion block 84, and the other end of the return spring 86 is connected to one side of the baffle 76. In actual implementation, by providing the return spring 86, when the extrusion block 84 is not squeezed, the return spring 86 applies elastic force to the extrusion block 84 to keep it stable. When the cam 83 moves away from the extrusion block 84, the return spring 86 applies elastic force to the extrusion block 84, and the elastic force drives the extrusion block 84 to move, thereby quickly restoring it.
