Opening and closing the slide plate 89 facilitates the storage or retrieval of the test ball. A limiting seat 811 is slidably connected to one side of the screening box 81. The limiting seat 811 is connected to one side of the screening box 81 via a spring 812. The spring 812 provides the necessary elasticity to the limiting seat 811, ensuring support or closure of the slide plate 89 during operation. The outer wall of the mounting part 2 is inserted into the inner walls of the base 1. This design not only enhances the stability of the overall structure. The support frame 3 is bolted to the upper end of the base 1, ensuring a secure connection between the support frame 3 and the base 1 and guaranteeing stable operation of the tester. One side of the inner wall of the screening box 81 is fixedly connected to one side of the guide plate 82, allowing materials to smoothly enter the screening plate 83 for screening. One side of the screening plate 83 is fixedly connected to the bottom of the other side of the inner wall of the screening box 81, ensuring the stability of the screening process. The inner diameters of the screening holes 84 and the guide groove 86 are different, allowing for the screening of particles of different sizes and improving the equipment's practicality. The discharge pipe 87 facilitates the discharge of the screened test balls, improving work efficiency. A sliding plate 89 is slidably connected to the inner wall of the slide rail 88.The sliding plate 89 allows for easy opening and closing of the discharge pipe 87, facilitating operation. The combined action of the limit seat 811 and spring 812 ensures that the limit seat 811 stably secures the position of the sliding plate 89, preventing it from accidentally falling.

[0030] To enable quick fixing and disassembly of the test plate 912, the lower end of the support plate 91 is firmly connected to the upper end of the support piece 6. The upper end of the support plate 91 has a slot 92 to accommodate the insert plate 911 at the lower end of the test plate 912. Both the front and rear ends of the support plate 91 have pressing shells 93. A toothed plate 94 is fixedly connected to the middle of the rear end of each pressing shell 93.

During use, the test ball will fall onto the sieve along the tilt angle of the test plate 912. Inside the separator 81, test balls slide down the guide plate 82 onto the screening plate 83. Depending on the size of the screening holes 84, test balls of different diameters fall from different screening holes 84 onto the guide seat 85, and then slide down the guide groove 86 into the discharge pipe 87. Pulling the handle 810 causes the slide plate 89 to slide along the inner wall of the slide rail 88, allowing the test balls in the discharge pipe 87 to be removed and collected. When it is necessary to release the fixed state of the slide plate 89, the user presses the corresponding limit seat 811. The limit seat 811 compresses the spring 812 and slides into the separator 81, separating the handle 810 from the limit seat 811. At this time, the slide plate 89 can be moved down along the slide rail 88 to release the discharge pipe 87. The device is easy to close and operate. When the test plate 912 needs to be replaced, press the pressing shell 93. The pressing shell 93 drives the toothed plate 94 to move. The toothed plate 94 drives the gear 95 to rotate. The gear 95 drives the toothed plate 97 to move. The toothed plate 97 drives the locking plate 99 to move and compress the spring 910. At this time, the locking plate 99 separates from the slot, and the insert plate 911 can be taken out from the slot 92. Then the test plate 912 can be removed for replacement. The reverse operation can fix the new test plate 912 on the support plate 91. The above is the working process of the whole device.
