[0027] See also Figure 1-4As shown, in this embodiment, a construction stone crusher is provided, comprising a feeding assembly 4 and a stone crushing device 2;

[0028] The stone crushing device 2 includes a box body 13, and two crushing rollers 21 are rotatably matched inside the box body 13. Both ends of the two crushing rollers 21 are provided with gears 28 that mesh with each other. A first motor 26 is provided on one side of the inner wall of the box body 13, and the output end of the first motor 26 is fixedly connected to one of the crushing rollers 21. Slide grooves 18 are provided on opposite sides of the inner wall of the box body 13. The other crushing roller 21 rotates and slides between the two slide grooves 18. A pushing device that cooperates with the crushing rollers 21 is provided on one side of the box body 13;

[0029] A material discharge inclined plate 33 is disposed in the box body 13 and is located below the two crushing rollers 21 . The material discharge inclined plate 33 and one side of the box body 13 form a material discharge port 34 .

[0030] One aspect of the application of this embodiment is as follows: through the provided feeding assembly 4, the crushed stone mixture to be crushed can be transported into the crushing device 2; through the provided crushing device 2, the crushed stone mixture can be crushed by the two internal crushing rollers 21 for later recycling; when the crushing rollers 21 are usually stuck by the steel bars, it is only necessary to manually push the pushing device so that the pushing device drives one of the crushing rollers 21 away from the other crushing roller 21, thereby releasing the jamming between the steel bars and the crushing rollers 21, so as to achieve a quick manual solution; and the crushed gravel and fallen gravel are discharged from the discharge port 34 to the outside of the discharge port 34, so as to be quickly collected by the staff, thereby achieving the recycling of the steel bars.

[0031] A screening assembly 3 is installed in the box body 13, and the screening assembly 3 includes a screening plate 31 obliquely installed below the crushing roller 21 and above the unloading inclined plate 33, and the screening plate 31 is provided with a leakage hole 32. A collecting box 14 is arranged in the box body 13, and a collecting port is opened on one side of the collecting box 14, and one end of the screening plate 31 is installed at the lower side of the collecting port.

[0032] The loading assembly 4 includes a base, on which a second motor 41 and four fixed pillars 46 are installed. Two second shafts 45 are rotatably engaged on the fixed pillars 46. Conveyor belts 43 are arranged on the two second shafts 45. Multiple pushing blocks 44 are arranged on the outer wall circumference of the conveyor belts 43. Pulleys are installed on one side of one of the second shafts 45 and the output end of the second motor 41, and a belt 42 is sleeved between the pulleys.

[0033] Two auxiliary plates 17 are installed at the top of both sides of the box body 13. A baffle 35 is installed in the box body 13. Four springs 36 are fixedly installed on the top of the baffle 35. A shock absorbing plate 37 is fixedly connected to the top of the spring 36.

[0034] First, the output end of the first motor 26 is started to drive one of the first shafts 22 to rotate, and then the first shaft 22 rotates to drive one of the crushing rollers 21 to rotate, and the gears 28 installed at one end of the two crushing rollers 21 are meshed, thereby driving the two crushing rollers 21 to rotate inward, thereby achieving the effect of crushing the stones, and then the crushed stones by the crushing rollers 21 fall to the leakage holes 32 of the screening plate 31 below, and then fall to the unloading inclined plate 33 through the leakage holes 32, so that the crushed stones are from the unloading inclined plate 33, thereby preventing the crushed stones from being crushed. The garbage and steel bars in the block are screened and separated. The separated garbage and steel bars will slide along the screening plate 31 into the collection box 14, and the output end of the second motor 41 is started to drive the second axis 45 to rotate, and then the belt 42 is driven to rotate through the rotation of the second axis 45, and then the conveyor belt 43 is driven to rotate through the belt 42. The rotation of the conveyor belt 43 drives the operation of the peripheral push block 44, thereby realizing the simplicity of the stone transportation process, and then the stone on the conveyor belt 43 falls into the shock-absorbing plate 37, which prevents the gravity of the stone from falling into and damaging the machine.

[0035] The pushing device of this embodiment includes a transverse push plate 23 rotatably engaged with one end of the two crushing rollers 21 and a connecting plate rotatably engaged between the two transverse push plates 23. A first axis 22 is installed on one side of the two transverse push plates 23. The two first axis 22 are rotatably engaged with two gears 28.

[0037] The first axis 22 is rotated by manually pushing the transverse push plate 23 upward, and the first axis 22 drives the crushing roller 21 at one end to move horizontally to one side. When the transverse push plate 23 moves upward, the pin 24 will move upward with it. When the transverse push plate 23 moves upward, one crushing roller 21 is away from the other crushing roller 21, thereby reducing the phenomenon that the two crushing rollers 21 have steel bars that cannot be crushed stuck inside when crushing stones. When the pin 24 is located in one of the slots 111, the gears 28 on the two crushing rollers 21 are meshed to ensure their stability, thereby achieving the goal of preventing the steel bars inside the crushing roller 21 from getting stuck during the stone crushing process, so as to facilitate maintenance.

[0038] In this embodiment, a storage block 15 is installed on the outer side of the box body 13, and a spray plate 110 is installed on the inner side of the box body 13. The storage block 15 is connected to the spray plate 110, and a water delivery port 16 is opened on one side of the storage block 15.

[0039] Water is poured into the storage block 15 from the water inlet 16 and then sprayed out from the spray plate 110 through the storage block 15, thereby reducing dust in the stone during the crushing process.

[0040] The present invention is not limited to the above-mentioned implementation modes. Anyone should be aware of the structural changes made under the inspiration of the present invention. Any technical solution that is the same or similar to the present invention falls within the protection scope of the present invention. The technology, shape, and structure that are not described in detail in the present invention are all known technologies.
