[0028] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.
[0029] This utility model provides an improved stone crushing value tester with screening function. The technical solution of this utility model is as follows:
[0030] like Figures 1-5 As shown, the stone crushing value tester with screening function includes a base plate 1, a box 14 fixedly connected to the top of the base plate 1, a fixed cylinder 15 fixedly connected to the top of the box 14, and a fixed frame 11 fixedly connected to the top of the base plate 1. An automatic discharge mechanism is located on the box 14. The automatic discharge mechanism includes a discharge unit and a drive unit. The discharge unit includes two fixed blocks 2 fixedly connected to the inner wall of the top of the box 14. A rotating plate 21 is rotatably connected to the two fixed blocks 2. The rotating plate 21 is located directly below the fixed cylinder 15. A fixed plate 22 is fixedly connected to one inner wall of the box 14. The fixed plate 22 is fixed to the box 14 by welding, making the fixed plate 22 more secure. A movable plate 23 is slidably connected to the fixed plate 22, and the movable plate 23 contacts the rotating plate 21. A connecting rod is fixedly connected to the top of the movable plate 23. The top of the connecting rod 25 and the housing 14 has a strip-shaped hole. The top of the connecting rod 25 is connected to a diagonal rod 26. The movable plate 23 is equipped with a telescopic spring 24. The two ends of the telescopic spring 24 are fixedly connected to the movable plate 23 and the fixed plate 22, respectively. The drive unit includes a telescopic hydraulic cylinder 12 fixedly connected to the fixed frame 11. The output end of the telescopic hydraulic cylinder 12 is fixedly connected to a pressure hammer 13. A pressing rod 27 is fixedly connected to the pressure hammer 13. The pressing rod 27 is in contact with the diagonal rod 26. With the automatic discharge mechanism, after the stones are crushed, the telescopic hydraulic cylinder 12 drives the pressure hammer 13 to reset, so that the pressing rod 27 presses the diagonal rod 26, which drives the connecting rod 25 and the movable plate 23 to reset. The movable plate 23 moves away from the rotating plate 21, so that the rotating plate 21 rotates downward and pours the crushed stones into the filter plate 18, thereby enabling automatic discharge of the crushed stones.
[0031] like Figure 2 As shown, in one embodiment, to facilitate the replacement of the filter plate 18, the filter plate 18 is fixed to the telescopic rod 16 by screwing. The telescopic rod 16 is fixedly connected to the top inner wall of the housing 14. The filter plate 18 and the guide plate 110 are fixedly connected to the upper part of the telescopic rod 16. The filter plate 18 is located directly above the guide plate 110. A return spring 17 is sleeved on the telescopic rod 16. The two ends of the return spring 17 are fixedly connected to the telescopic rod 16 and the housing 14, respectively. Through the setting of the filter plate 18, the stones are filtered, so that larger stones and smaller stones can be separated.
[0032] like Figure 2As shown, in one embodiment, two collection boxes 19 are slidably connected to the housing 14. The two collection boxes 19 are located at the discharge ends of the filter plate 18 and the guide plate 110, respectively. The collection boxes 19 are used to collect stones.
[0033] like Figure 3 As shown, in one embodiment, to make the cam 34 more secure, the cam 34 is fixed to the rotating rod 32 by welding. The rotating rod 32 is fixedly connected to the inner wall of the housing 14, and the cam 34 is fixedly connected to one end of the rotating rod 32. The cam 34 is adapted to the filter plate 18. A gear 33 is fixedly sleeved on the rotating rod 32. An L-shaped rod 3 is fixedly connected to the movable plate 23. A rack 31 is fixedly connected to the bottom end of the L-shaped rod 3, and the rack 31 meshes with the gear 33. With the setting of the cam 34, the movable plate 23 moves, driving the L-shaped rod 3 and the rack 31 to move. The movement of the rack 31 drives the gear 33, the rotating rod 32 and the cam 34 to rotate. With the cooperation of the cam 34 and the return spring 17, the filter plate 18 and the guide plate 110 vibrate, which improves the screening effect of the filter plate 18 on stones.
[0034] like Figure 4 As shown, in one embodiment, a feed box 4 is fixedly connected to the fixed cylinder 15, a baffle plate 41 is slidably connected to the feed box 4, an mounting block 42 is fixedly connected to the baffle plate 41, a fixed shaft 43 is fixedly connected to the feed box 4, and a rotating rod 44 is fixedly sleeved on the fixed shaft 43. The rotating rod 44 and the mounting block 42 are in contact. With the setting of the rotating rod 44, when the pressure hammer 13 enters the fixed cylinder 15 and contacts the rotating rod 44, it drives the rotating rod 44 to rotate. The rotation of the rotating rod 44 drives the mounting block 42 and the baffle plate 41 to move upward, so that the stones in the feed box 4 enter the fixed cylinder 15 and fall on the rotating plate 21, thereby enabling the feeding of stones.
[0035] The specific working method is as follows: Place the stones to be crushed into the feed box 4. Activate the telescopic hydraulic cylinder 12 to move the hammer 13 downwards. The movement of the hammer 13 moves the extrusion rod 27, causing it to move away from the inclined rod 26. Since the telescopic spring 24 is compressed, it causes the movable plate 23, connecting rod 25, and inclined rod 26 to reset. The reset of the movable plate 23 causes the rotating plate 21 to rotate, making it fit against the inner top wall of the box 14. When the hammer 13 enters the fixed cylinder 15 and contacts the rotating rod 44, it drives the rotating rod 44 to rotate. The rotation of the rotating rod 44 causes the mounting block 42 and the baffle plate 41 to move upwards, allowing the stones in the feed box 4 to enter the fixed cylinder 15 and fall onto the rotating plate 21. As the hammer 13 continues to move downwards, it crushes the stones. Then, the telescopic hydraulic cylinder... 12 drives the hammer 13 to reset, causing the pressing rod 27 to press the inclined rod 26, which in turn drives the connecting rod 25 and the movable plate 23 to reset. The movable plate 23 moves away from the rotating plate 21, causing the rotating plate 21 to rotate downwards and pour the crushed stones into the filter plate 18. This allows for automatic discharge of the crushed stones. After being filtered by the filter plate 18, larger stones enter one of the collection boxes 19, while smaller stones fall into the guide plate 110 and then into the other collection box 19. This process allows for the screening and collection of the stones. The movement of the movable plate 23 drives the L-shaped rod 3 and the rack 31 to move. The movement of the rack 31 drives the gear 33, the rotating rod 32, and the cam 34 to rotate. The cam 34 and the reset spring 17 work together to cause the filter plate 18 and the guide plate 110 to vibrate, improving the screening effect of the filter plate 18 on the stones.
