Technical Field
[0001] This utility model relates to the field of stone processing technology, specifically to a crushing device for stone processing. Background Technology
[0002] With the advancement of urbanization, new buildings are erected every day. Construction engineering refers to the engineering entity formed by the construction activities of houses and their ancillary facilities. Stone is one of the essential raw materials during construction. In engineering construction, a large quantity of stone is needed, and the sizes of the stone vary. For those large stones, they cannot be used directly in engineering construction and need to be crushed before they can be used in engineering. This requires crushing equipment to crush the stone.
[0003] Existing stone crushing devices typically cannot completely crush stones in one step, requiring the crushed stones to be sieved, crushed a second time, or even a third time. This crushing process is cumbersome, has low efficiency, and stones are prone to flying out of the crushing chamber, causing injury to nearby workers and requiring cleanup, which is time-consuming, labor-intensive, and increases the workload of workers. Therefore, a stone crushing device is proposed to solve the above-mentioned problems. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] In the embodiments, by Figures 1-5 A crushing device for stone processing is provided. The present invention includes a crushing box 1, characterized in that: a fixed cylinder 2 is rotatably connected inside the crushing box 1, a rotating column 3 is rotatably connected inside the fixed cylinder 2 and rotatably connected to the inside of the crushing box 1, a crushing blade 4 is fixedly connected to the outside of the rotating column 3, a first motor 5 is fixedly connected to the outside of the crushing box 1 and its output shaft is fixedly connected to the rotating column 3, a discharge hole 6 is opened inside the fixed cylinder 2, a feed hopper 7 extending to the upper side of the crushing box 1 is fixedly connected to the top of the fixed cylinder 2, a spring 8 is fixedly connected to the inner side wall of the feed hopper 7, and a rotating plate 9 is fixedly connected to the end of the spring 8 away from the inner wall of the feed hopper 7, and the rotating plate 9 is rotatably connected to the inside of the feed hopper 7.
[0028] Stones are fed into the hopper 7. The weight of the stones causes the rotating plate 9 to rotate around the connecting column 10 towards the inside of the hopper 7. The spring 8 is compressed. After the stones enter the fixed cylinder 2, the spring 8 returns to its original position, which in turn causes the rotating plate 9 to return to its original position and block the upper side of the hopper 7. This prevents the stones from splashing out of the fixed cylinder 2 when they are broken, thus preventing injury to the surrounding workers. Then, the first motor 5 is started, which causes the rotating column 3 to drive the crushing blade 4 to rotate and crush the stones inside the fixed cylinder 2. Stones smaller than the diameter of the discharge hole 6 fall from the discharge hole 6 to the top of the lower inclined plate 15 and then slide out of the crushing box 1. Stones that are not completely crushed continue to be crushed inside the fixed cylinder 2 until the crushed diameter is qualified.
[0029] Specifically, refer to Figure 3 The feed hopper 7 is rotatably connected to a connecting column 10, which is fixedly connected to the outer side of the rotating plate 9.
[0030] In this embodiment, stones are thrown into the feed hopper 7. The weight of the stones causes the rotating plate 9 to rotate around the connecting column 10 towards the inside of the feed hopper 7. The spring 8 is compressed. When the stones enter the fixed cylinder 2, the spring 8 returns to its original position, driving the rotating plate 9 back to its original position.
[0031] Specifically, refer to Figure 2 and Figure 3 The inner wall of the fixed cylinder 2 is fixedly connected with a breaking tooth 11, and the number of springs 8 is four and they are symmetrically distributed.
[0032] In this embodiment, the crushing tooth 11 thoroughly crushes the stone located inside the fixed cylinder 2, speeding up the crushing time and improving the crushing efficiency of the stone.
[0033] Specifically, refer to Figure 1 , Figure 2 and Figure 5 A second motor 12 is fixedly connected to the outside of the crushing box 1. The output shaft of the second motor 12 is fixedly connected to a half gear 22 that is rotatably connected to the inside of the crushing box 1. A fixed rod 21 is fixedly connected to the inner wall of the crushing box 1. A rack 24 that meshes with the half gear 22 is slidably connected to the outside of the fixed rod 21. A fixed column 13 is fixedly connected to the outside of the rack 24. A cam 14 is fixedly connected to the outside of the fixed column 13. A spring 23 is fixedly connected to the outside of the fixed rod 21.
[0034] In this embodiment, the second motor 12 is started, which causes the half gear 22 to drive the rack 24 to slide downward. The rack 24 drives the fixed column 13 to slide downward. The fixed column 13 drives the cam 14 to move downward. Through compression by 23, the half gear 22 rotates until it no longer meshes with the rack 24. The spring 23 returns to its original state, which causes the rack 24 to move upward, driving the fixed column 13 to move upward. This causes the cam 14 to hit the bottom of the fixed cylinder 2, so that the completely broken stones inside the fixed cylinder 2 fall to the top of the inclined plate 15, preventing the stones from getting stuck inside the discharge hole 6 and blocking the discharge hole 6, thus affecting the discharge of other stones.
[0035] Specifically, refer to Figure 2 , Figure 3 and Figure 4 The crushing box 1 is fixedly connected to an inclined plate 15 located on the lower side of the fixed cylinder 2, and the crushing box 1 has a discharge port 16 located on the front side of the inclined plate 15.
[0036] In this embodiment, the stones falling from the inside of the fixed cylinder 2 land on the top of the inclined plate 15. Due to the tilting effect of the inclined plate 15, they slide out of the inside of the crushing box 1 through the discharge port 16.
[0037] Specifically, refer to Figure 1 and Figure 2 A third motor 17 is fixedly connected to the outside of the crushing box 1. A reciprocating screw 18 is fixedly connected to the output shaft of the third motor 17. A scraper 19 is threadedly connected to the outside of the reciprocating screw 18 and is slidably connected to the inner wall of the crushing box 1. The bottom of the scraper 19 is slidably connected to the inclined plate 15. A control panel 20 is fixedly connected to the outside of the crushing box 1.
[0038] In this embodiment, the control panel 20 controls the start of the third motor 17, causing the reciprocating screw 18 to rotate, thereby causing the scraper 19 to drive the remaining stone fragments on the inclined plate 15 to slide out of the crushing box 1 through the discharge port 16.
[0039] Working principle:
[0040] First: The stones are put into the feed hopper 7. The weight of the stones causes the rotating plate 9 to rotate around the connecting column 10 towards the inside of the feed hopper 7. The spring 8 is compressed. After the stones enter the fixed cylinder 2, the spring 8 returns to its original position, which in turn causes the rotating plate 9 to return to its original position and block the upper side of the feed hopper 7, thereby preventing the stones from flying out of the fixed cylinder 2 when they break and causing injury to the surrounding workers.
[0041] Then: The control panel 20 then starts the first motor 5, which causes the rotating column 3 to drive the crushing blade 4 to rotate and crush the stones inside the fixed cylinder 2. After crushing, the stones smaller than the diameter of the discharge hole 6 fall from the discharge hole 6 to the top of the lower inclined plate 15 and then slide out of the crushing box 1. The stones that are not completely crushed continue to be crushed inside the fixed cylinder 2 until the crushed diameter is qualified.
