The second rotating shaft 17 is rotatably connected with a movable jaw plate 18. A fixed jaw plate 19 located at the same height as the movable jaw plate 18 is fixed in the upper frame 11.

The facing sides of the first movable tooth plate 112 and the second movable tooth plate 113 are both provided with evenly distributed straight plates, which are used to prevent the two ends of the steel bars in the concrete from pressing against the first movable tooth plate 112 when crushing concrete. The movable tooth plate 112 and the second movable tooth plate 113, the first movable tooth plate 112 is limitedly slidably connected with a telescopic connecting frame 114 which is slidably connected to the upper frame 11, a convex rod is provided on the right part of the telescopic connecting frame 114, and an inclined annular groove is provided on the first rotating shaft 16 on the front side. The convex rod on the telescopic connecting frame 114 slides in the inclined annular groove on the first rotating shaft 16 on the front side, and is used to drive the first movable tooth plate 112 to reciprocate back and forth. A crushing auxiliary mechanism 2 for moving the second movable tooth plate 113 is provided on the upper frame 11.

[0038] like Figure 6-Figure 8As shown, the crushing auxiliary mechanism 2 includes two third fixed plates 21 symmetrically distributed up and down, and the two third fixed plates 21 symmetrically distributed up and down are fixedly connected to the right side of the lower part of the upper frame 11. The right side of the third fixed plate 21 is rotatably connected to a fixed shaft 22 rotatably connected to the upper frame 11. The symmetrically distributed fixed shafts 22 are jointly provided with a first sliding plate 23. The left side of the first sliding plate 23 is fixedly connected to a first hydraulic cylinder 24. A first piston 25 is slidably connected in the first hydraulic cylinder 24. The first piston 25 is hinged to the movable jaw plate 18. There is a connecting rod 26, and a second hydraulic cylinder 27 is fixedly connected to the upper side of the first fixed plate 14. The second hydraulic cylinder 27 is connected to the first hydraulic cylinder 24 through a pipeline. A second piston 28 is slidably connected in the second hydraulic cylinder 27. The second hydraulic cylinder 27, the first hydraulic cylinder 24 and the pipeline therebetween are all filled with hydraulic oil. A support plate 29 is fixedly connected to the upper side of the second piston 28. The support plate 29 is used to support the second movable tooth plate 113. A crushing and compensating pressure assembly 3 for maintaining the position of the second movable tooth plate 113 is provided on the first fixed plate 14.

[0039] like Figure 8 As shown, the crushing and compensating pressure assembly 3 includes a third hydraulic cylinder 31, which is fixedly connected to the upper side of the first fixed plate 14, and the third hydraulic cylinder 31 is connected to the second hydraulic cylinder 27 through a pipeline, and the pipeline and the third hydraulic cylinder 31 are full of hydraulic oil, and a third piston 32 is slidably connected in the third hydraulic cylinder 31, a second motor 33 is installed on the upper side of the first fixed plate 14, and the output shaft of the second motor 33 is fixedly connected to a fixed wheel 34, and a fixed rod is provided at the eccentric position of the fixed wheel 34, a T-shaped rod is provided on the upper side of the third piston 32, and a sliding groove slidably connected to the fixed rod at the eccentric position of the fixed wheel 34 is provided in the cross bar of the T-shaped rod.

[0040] Initially, the protruding column in the telescopic connecting frame 114 is located at the front side of the inclined annular groove on the first rotating shaft 16 .

[0041] When it is necessary to crush concrete materials, the staff starts the loading device 12, the unloading device 13, the first motor 15 and the second motor 33 through the control panel, and then the staff places the concrete materials on the upper side of the loading device 12, and the loading device 12 transports the concrete materials to the upper frame 11. The concrete materials entering the upper frame 11 fall on the upper side of the unloading device 13 after being crushed, and the unloading device 13 transports the crushed concrete materials away.

[0042] During the operation of the first motor 15, the output shaft of the first motor 15 rotates the first rotating shaft 16 on the rear side through the pulley and the belt transmission, the first rotating shaft 16 drives the second rotating shaft 17 to rotate through the eccentric part thereon (the rotation method of the second rotating shaft 17 is similar to that of a crankshaft), the second rotating shaft 17 drives the upper part of the movable jaw plate 18 to move left and right, the movable jaw plate 18 drives the first movable tooth plate 112 to move left and right, the first movable tooth plate 112 moves left and right and cooperates with the second movable tooth plate 113 to squeeze and crush the concrete material between the two, until the concrete material between the first movable tooth plate 112 and the second movable tooth plate 113 can pass through the gap between the lower parts of the two, and the crushed concrete material falls on the upper side of the unloading device 13.

[0043] During the rotation of the first rotating shaft 16 on the front side, the first rotating shaft 16 on the front side drives the telescopic connecting frame 114 and the convex column thereon to reciprocate back and forth through the inclined annular groove thereon, and the telescopic connecting frame 114 drives the first movable tooth plate 112 to reciprocate back and forth. Therefore, during the operation of the first motor 15, the first movable tooth plate 112 moves left and right as well as forward and backward. In this way, when squeezing and crushing the concrete between the first movable tooth plate 112 and the second movable tooth plate 113, the forward and backward movement of the first movable tooth plate 112 cooperates with the second movable tooth plate 113 to squeeze and rub the concrete between the two by the forward and backward movement of the first movable tooth plate 112, thereby avoiding damage to the first movable tooth plate 112 and the second movable tooth plate 113 due to the two ends of the steel bars in the concrete pressing on the first movable tooth plate 112 and the second movable tooth plate 113 when squeezing and crushing the concrete between the two.

[0044] During the left-right movement of the upper portion of the movable jaw plate 18 (i.e., during the operation of the first motor 15), the movable jaw plate 18 drives the connecting rod 26 to move left-right, and at the same time, the output shaft of the second motor 33 drives the fixed wheel 34 to rotate, and the fixed wheel 34 rotates through the cylinder at its eccentric position to drive the third piston 32 to move up and down, and in this process, only the following two situations will occur:

[0045] 1. When the connecting rod 26 moves to the left, the third piston 32 moves downward;

[0046] 2. When the connecting rod 26 moves to the right, the third piston 32 moves upward.

[0047] The following is a detailed description of these two situations:

[0048] In the first case (i.e., when the connecting rod 26 moves to the left, the third piston 32 moves downward, and these two actions are performed synchronously), the connecting rod 26 drives the first piston 25 to move to the left to suck out the hydraulic oil in the second hydraulic cylinder 27, and the amount of hydraulic oil in the second hydraulic cylinder 27 decreases. During this process, the third piston 32 moves downward to squeeze the hydraulic oil in the third hydraulic cylinder 31 into the second hydraulic cylinder 27 through the pipeline, thereby replenishing the hydraulic oil in the second hydraulic cylinder 27 and keeping the amount of hydraulic oil in the second hydraulic cylinder 27 unchanged.

[0049] In the second case (i.e., when the connecting rod 26 moves to the right, the third piston 32 moves upward, and these two actions are performed synchronously), the connecting rod 26 drives the first piston 25 to move to the right to squeeze the hydraulic oil in the first hydraulic cylinder 24 back into the second hydraulic cylinder 27 through the pipeline, and the amount of hydraulic oil in the second hydraulic cylinder 27 increases. During this process, the third piston 32 moves upward to draw the hydraulic oil in the second hydraulic cylinder 27 back into the third hydraulic cylinder 31 through the pipeline, so that the amount of hydraulic oil in the second hydraulic cylinder 27 remains unchanged.

[0050] Through the above two situations, the second piston 28 and the support plate 29 do not move downward (that is, the second movable tooth plate 113 does not move downward) until the speed of the first movable tooth plate 112 moving to the left slows down (that is, when the two ends of the steel bars in the concrete press against the first movable tooth plate 112 and the second movable tooth plate 113), the speed at which the first piston 25 extracts hydraulic oil is lower than the speed at which the third piston 32 squeezes the hydraulic oil downward, and the second piston 28 drives the second movable tooth plate 113 to move upward through the support plate 29, and the second movable tooth plate 113 moves upward to rub the concrete between it and the first movable tooth plate 112, thereby avoiding that when the first movable tooth plate 112 and the second movable tooth plate 113 squeeze and crush the concrete between them, the two ends of the steel bars in the concrete press against the first movable tooth plate 112 and the second movable tooth plate 113, causing the first movable tooth plate 112 and the second movable tooth plate 113 to be damaged.

[0051] In the above process, when the speed of the first movable tooth plate 112 moving to the left is restored, the connecting rod 26 drives the first piston 25 to move to the left again to suck out the hydraulic oil in the second hydraulic cylinder 27, and the amount of hydraulic oil in the second hydraulic cylinder 27 is reduced. During this process, the third piston 32 continues to move downward to squeeze the hydraulic oil in the third hydraulic cylinder 31 into the second hydraulic cylinder 27 through the pipeline to replenish the hydraulic oil in the second hydraulic cylinder 27. Therefore, the hydraulic oil in the second hydraulic cylinder 27 is in a state of dynamic balance again, so that the position of the second movable tooth plate 113 no longer changes until the third piston 32 moves downward to the lowest point (that is, after the fixed wheel 34 rotates 180°), the control panel turns off the second motor 33, and the first piston 25 continues to move to the left to suck out the hydraulic oil in the second hydraulic cylinder 27, so that the second movable tooth plate 113 moves downward and resets, until the second movable tooth plate 113 is reset to the initial state, the control panel restarts the second motor 33, so that the connecting rod 26 moves to the right and the action of the third piston 32 moving upward begins to match again.

[0052] In this embodiment, the relationship between the second fixed plate 110 and the limiting shaft 111 is fixed, and the relationship between the two fixed shafts 22 and the first sliding plate 23 is fixed, and the fixed shafts 22 on the upper and lower sides can be made of ordinary straight rods. However, in other embodiments, if there is no specific description, the second fixed plate 110 is slidably connected to the limiting shaft 111, the upper fixed shaft 22 is still made of an ordinary straight rod, and the upper fixed shaft 22 and the first sliding plate 23 are slidably connected, and the lower fixed shaft 22 is replaced by a screw, and the lower fixed shaft 22 and the first sliding plate 23 are threadedly connected.

[0053] After investigation and research, it was found that when construction waste is reused, it involves different fields, but the particle size of construction waste required in different fields is also different. When the existing crushing device crushes construction waste, the particle size of the construction waste it produces is relatively fixed, and the particle size of the construction waste produced cannot be adjusted according to the actual usage scenario, and its applicability is low.

[0054] Embodiment 2: Based on embodiment 1, Figure 6 and Figure 7As shown, it also includes a particle size adjustment mechanism 4, which is used to adjust the distance between the first movable tooth plate 112 and the second movable tooth plate 113. The particle size adjustment mechanism 4 is arranged in the upper frame 11, and the particle size adjustment mechanism 4 includes a second sliding plate 41, and the second sliding plate 41 is slidably connected to the right side of the upper frame 11. A first elastic member 42 is connected between the second sliding plate 41 and the second fixed plate 110, and the first elastic member 42 is a spring. The second sliding plate 41 is limitedly rotated and connected to a first rotating rod 43, that is, the first rotating rod 43 can drive the second sliding plate 41 to rotate. The movable plate 41 moves, and the first rotating rod 43 is threadedly connected to the second fixed plate 110. The first rotating rod 43 and the lower fixed shaft 22 are driven by a pulley and a belt. The first rotating rod 43 is splined to the pulley thereon, and the first rotating rod 43 and the pulley on the lower fixed shaft 22 are connected to rotate together with a connecting piece for maintaining the position of the pulley on the first rotating rod 43. The lower fixed shaft 22 is threadedly connected to the first sliding plate 23, the upper fixed shaft 22 is slidably connected to the first sliding plate 23, and the second fixed plate 110 is slidably connected to the limit shaft 111.

[0055] When it is necessary to adjust the distance between the first movable tooth plate 112 and the second movable tooth plate 113, the staff rotates the first rotating rod 43, and the first rotating rod 43 cooperates with the second fixed plate 110 through the thread thereon. The first rotating rod 43 drives the second sliding plate 41 to move to the right, stretching the first elastic member 42, and the second sliding plate 41 drives the limiting shaft 111 to move to the right. The limiting shaft 111 drives the movable jaw plate 18 to move to the right, thereby increasing the distance between the first movable tooth plate 112 and the second movable tooth plate 113.

[0056] During the rotation of the first rotating rod 43, the first rotating rod 43 rotates the fixed shaft 22 on the lower side through the pulley and belt drive, and the fixed shaft 22 on the lower side drives the first sliding plate 23 to move to the right through the thread thereon, and the first sliding plate 23 drives the first hydraulic cylinder 24 to move to the right, and the first hydraulic cylinder 24 drives the first piston 25 to move to the right through the hydraulic oil therein, and the first piston 25 drives the connecting rod 26 to move to the right to adapt to the movable jaw plate 18 to move to the right, and then the crushing process in Example 1 is repeated.

[0057] Embodiment 3: Based on embodiment 2, Figure 9-11As shown, it also includes an anti-blocking and crushing mechanism 5, which is arranged on the upper frame 11. The anti-blocking and crushing mechanism 5 is used to prevent the concrete blocks in the upper frame 11 from being blocked. The anti-blocking and crushing mechanism 5 includes symmetrically distributed threaded rods 51, and the symmetrically distributed threaded rods 51 are all rotatably connected to the upper part of the upper frame 11. The threaded rods 51 are reciprocating screws. The symmetrically distributed threaded rods 51 are commonly threadedly connected to a sliding frame 52, and the lower side of the sliding frame 52 is fixedly connected with evenly distributed crushing members 54. The lower end of the crushing member 54 is set to a cone, which is used to crush concrete blocked between the first movable tooth plate 112 and the second movable tooth plate 113. An anti-blocking and crushing trigger component 6 for triggering the sliding frame 52 to move downward is provided on the upper frame 11.

[0058] like Figure 9-11 As shown, the anti-blocking and crushing trigger assembly 6 includes a symmetrically distributed second rotating rod 61, which is symmetrically distributed and rotatably connected to the lower part of the upper frame 11. The second rotating rod 61 and the adjacent first rotating shaft 16 are driven by a pulley and a belt. The second rotating rod 61 is fixedly connected with a friction wheel. The lower part of the upper frame 11 is rotatably connected with a symmetrically distributed third rotating rod 62. The third rotating rod 62 is fixedly connected with a friction wheel. The upper part of the upper frame 11 is rotatably connected with a symmetrically distributed fourth rotating rod 63. The fourth rotating rod 63 and the adjacent threaded rod 51 are driven by a bevel gear set. The fourth rotating rod 63 and the adjacent third rotating rod 62 are driven by a pulley and a belt. The lower part of the upper frame 11 is fixedly connected with a fourth fixed plate 64, and the fourth fixed plate 64 is slidably connected There is a trigger plate 65 located between the upper frame 11 and the unloading device 13. The distance between the fourth fixed plate 64 and the unloading device 13 and the trigger plate 65 is consistent. After the crushed concrete block falls on the upper side of the trigger plate 65, the concrete block rolls down onto the unloading device 13 along the upper side of the trigger plate 65 to prevent the concrete block from damaging the unloading device 13. A second elastic member 66 is connected between the fourth fixed plate 64 and the trigger plate 65. The trigger plate 65 is rotatably connected to a symmetrically distributed fifth rotating rod 67. The fifth rotating rod 67 is fixedly connected to a friction wheel. The friction wheels on the second rotating rod 61 and the third rotating rod 62 are frictionally matched with the friction wheels on the adjacent fifth rotating rod 67, so that the second rotating rod 61 drives the third rotating rod 62 to rotate through the fifth rotating rod 67.

[0059] When the first movable tooth plate 112 and the second movable tooth plate 113 are crushing the concrete block, the crushed concrete block falls on the trigger plate 65 and squeezes the trigger plate 65 to move downward, thereby compressing the two second elastic members 66. When the concrete block is blocked between the first movable tooth plate 112 and the second movable tooth plate 113, no more concrete block falls on the trigger plate 65. Under the action of the two second elastic members 66, the trigger plate 65 moves upward, and the trigger plate 65 drives the two fifth rotating rods 67 to move upward. The two fifth rotating rods 67 respectively drive the adjacent friction wheels to move upward until the friction wheels on the fifth rotating rod 67 contact the friction wheels on the adjacent second rotating rod 61 and the adjacent third rotating rod 62. The first rotating shaft 16 is driven by the pulley and the belt. The adjacent second rotating rod 61 is driven to rotate, and the second rotating rod 61 drives the friction wheel on the adjacent fifth rotating rod 67 to rotate through the friction wheel thereon, and the friction wheel on the fifth rotating rod 67 drives the friction wheel on the adjacent third rotating rod 62 to rotate, and the third rotating rod 62 drives the adjacent fourth rotating rod 63 to rotate through the pulley and the belt, and the fourth rotating rod 63 drives the adjacent threaded rod 51 to rotate through the bevel gear set, and the threaded rod 51 drives the crushing member 54 to reciprocate up and down through the threaded transmission sliding frame 52 thereon, so as to crush the concrete blocks between the first movable tooth plate 112 and the second movable tooth plate 113, so as to prevent the concrete blocks from being blocked between the first movable tooth plate 112 and the second movable tooth plate 113, thereby affecting the efficiency of the first movable tooth plate 112 and the second movable tooth plate 113 in crushing the concrete blocks.
