DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0021] Embodiment 1, refer to Figure 1-Figure 8A crushing and sand making device that can be produced according to different gradations includes a frame 1, a rectangular box 2 is arranged on the top of the frame 1, a cylinder 21 is fixed on the side of the rectangular box 2, a mounting shell 22 is fixed at one end of the extension rod of the cylinder 21, a circular block 23 is fixed in the mounting shell 22, a crushing box 3 is fixed on the top of the rectangular box 2, a cross bar 31 is fixed in the crushing box 3, a slider 32 is slid on the outer surface of the cross bar 31, a rectangular frame 33 is fixed between the sliders 32, a crushing mechanism is arranged in the rectangular frame 33, a filter hole 34 is opened at the bottom of the crushing box 3, the filter hole 34 is adapted to the size of the circular block 23, and a material drop port 4 is connected to the top of the crushing box 3, and also includes: A material discharge mechanism 5 is arranged on the top of the crushing box 3, and the material discharge mechanism 5 is used to discharge materials into the discharge opening 4; An adjusting mechanism 6 installed in the blanking opening 4, the adjusting mechanism 6 is used to adjust the position of the blanking mechanism 5; An impact mechanism 7 disposed on the crushing box 3, the impact mechanism 7 is used to vibrate the rectangular frame 33; A blocking mechanism 8 installed on the material discharging mechanism 5, the blocking mechanism 8 is used to make the sand and gravel in the material discharging mechanism 5 fall intermittently; An air blowing mechanism 9 is arranged in the crushing box 3 , and is used for blowing air into the rectangular frame 33 .

[0022] Furthermore, the unloading mechanism 5 includes a storage hopper 51 arranged above the drop port 4, the bottom of the storage hopper 51 is connected to a unloading pipe 52, a vertical bar 53 is fixed to the top of the crushing box 3, a fixed rod 54 is fixed between the two vertical bars 53, a movable bar 55 is slid on the outer surface of the fixed rod 54, and the unloading pipe 52 is fixed in the middle of the movable bar 55.

[0023] Furthermore, the adjustment mechanism 6 includes a servo motor 61 fixed on the side of the blanking port 4, a turntable 62 is fixed to the output shaft end of the servo motor 61, a pushing head 63 is fixed to the front side of the turntable 62, an arc-shaped shell 64 is slid on the outer surface of the pushing head 63, and a vertical rod 65 is fixed to the side of the arc-shaped shell 64 away from the turntable 62, and the top of the vertical rod 65 is fixedly connected to the moving bar 55.

[0024] Furthermore, the adjustment mechanism 6 also includes limiting rods 66 fixed on two side surfaces of the arc-shaped shell 64 , and the limiting rods 66 slide through the adjacent side walls of the blanking opening 4 .

[0025] It should be noted that: the storage hopper 51 is set up to store sand and gravel, and the movable bar 55 slides on the outer surface of the fixed rod 54 and the discharge tube 52 is connected to the movable bar 55, so that the storage hopper 51 and the discharge tube 52 can slide and are in an unfixed state. The servo motor 61 is set up to drive the turntable 62 to rotate, and the turntable 62 drives the push head 63 to make a circular motion. Since the arc shell 64 is slidably connected to the push head 63 and the limit rod 66 is slidably connected to the inner wall of the discharge port 4, the circular motion of the push head 63 will drive the arc shell 64 to move left and right, and the arc shell 64 drives the vertical rod 65 to move left and right, and the vertical rod 65 drives the movable bar 55 and the discharge tube 52 to move together.

[0026] A further advantage of adopting the above method is that the storage hopper 51 and the discharge pipe 52 can be moved left and right, so that the fallen sand and gravel are reasonably distributed on the surface of the crushing roller and will not gather in the middle of the crushing roller, thereby avoiding excessive wear of the crushing teeth in the middle of the crushing roller due to excessive pressure after long-term use, thereby causing damage to the equipment.

[0027] Specifically, when in use, sand and gravel are placed in the storage hopper 51. When crushing, the crushing mechanism installed on the rectangular frame 33 is started. The crushing mechanism can be composed of a driving motor, two mutually meshing gears and two crushing rollers. The driving motor drives one of the gears and the crushing roller to rotate, thereby driving the other gear and the crushing roller to rotate to crush the sand and gravel. At the same time, the servo motor 61 is started to move the storage hopper 51 and the discharge pipe 52 left and right, so that the sand and gravel are reasonably distributed on the surface of the crushing roller through the discharge port 4. After being crushed, the sand and gravel fall to the bottom of the crushing box 3. Since the rectangular frame 33 fits the bottom of the crushing box 3, the crushed sand and gravel pass through The filter hole 34 falls down, and the sand and gravel that does not reach the required size continues to be crushed until it can pass through the filter hole 34. Through the setting of the cylinder 21, the mounting shell 22 can be driven to move, and the mounting shell 22 drives the circular block 23 to move. Since the circular block 23 is adapted to the size of the filter hole 34, the area covered by the filter hole 34 can be changed by moving the circular block 23, so that the diameter of the filter hole 34 falling can be adjusted to complete the production of sand and gravel with different gradations. The rectangular box 2 can slide on the top of the frame 1, and a vibration component is installed on the frame 1 to make the rectangular box 2 move back and forth, so that the sand and gravel in the filter hole 34 can fall more easily.

[0028] Example 2, refer to Figure 1-Figure 8A crushing and sand making device that can be produced according to different gradations includes a frame 1, a rectangular box 2 is arranged on the top of the frame 1, a cylinder 21 is fixed on the side of the rectangular box 2, a mounting shell 22 is fixed at one end of the extension rod of the cylinder 21, a circular block 23 is fixed in the mounting shell 22, a crushing box 3 is fixed on the top of the rectangular box 2, a cross bar 31 is fixed in the crushing box 3, a slider 32 is slid on the outer surface of the cross bar 31, a rectangular frame 33 is fixed between the sliders 32, a crushing mechanism is arranged in the rectangular frame 33, a filter hole 34 is opened at the bottom of the crushing box 3, the filter hole 34 is adapted to the size of the circular block 23, and a material drop port 4 is connected to the top of the crushing box 3, and also includes: A material discharge mechanism 5 is arranged on the top of the crushing box 3, and the material discharge mechanism 5 is used to discharge materials into the discharge opening 4; An adjusting mechanism 6 installed in the blanking opening 4, the adjusting mechanism 6 is used to adjust the position of the blanking mechanism 5; An impact mechanism 7 disposed on the crushing box 3, the impact mechanism 7 is used to vibrate the rectangular frame 33; A blocking mechanism 8 installed on the material discharging mechanism 5, the blocking mechanism 8 is used to make the sand and gravel in the material discharging mechanism 5 fall intermittently; An air blowing mechanism 9 is arranged in the crushing box 3 , and is used for blowing air into the rectangular frame 33 .

[0029] Furthermore, the impact mechanism 7 includes a rack 1 71 fixed to the end of the limiting rod 66 away from the arc-shaped shell 64, the bottom of the rack 1 71 is meshed with a connecting gear 72, a rotating rod 73 is fixed at the axis of the connecting gear 72, and the rotating rod 73 is rotatably connected to the crushing box 3 through a bearing, and the outer surface of the connecting gear 72 is meshed with a rack 2 74, and the side of the rack 2 74 is fixed with an L-shaped rod 75 through a connecting strip, the right end of the L-shaped rod 75 slides on the inner wall of the crushing box 3 and is fixed with a rubber head 76, and the inner wall of the crushing box 3 is also provided with a telescopic part 77, the side of the crushing box 3 is fixed with a limiting strip 78, and the bottom of the rack 2 74 is fixed with a limiting block 79, and the limiting block 79 slides on the outer surface of the limiting strip 78.

[0030] Furthermore, the telescopic part 77 includes an oil storage cylinder 771 fixed to the inner wall of the crushing box 3, and an extrusion rod 772 slides inside the oil storage cylinder 771. The end of the extrusion rod 772 away from the oil storage cylinder 771 is fixedly connected to the rectangular frame 33, and the outer surface of the extrusion rod 772 is sleeved with a spring 773. The two ends of the spring 773 are respectively fixedly connected to the rectangular frame 33 and the oil storage cylinder 771.

[0031] It should be noted that: the rack 1 71 is connected to the limit rod 66. When the servo motor 61 drives the turntable 62 and the push head 63 to rotate and drive the arc-shaped shell 64 and the limit rod 66 to move left and right, the rack 1 71 can be synchronously driven to move left and right. The rack 1 71 is meshed with the connecting gear 72. When the rack 1 71 moves to the left, the connecting gear 72 and the rotating rod 73 can be driven to rotate. The connecting gear 72 is meshed with the rack 2 74. Therefore, when the rack 1 71 moves to the left, the rack 2 74 can be driven to move in the opposite direction of the rack 1 71, that is, to the right. The L-shaped rod 75 is connected to the rack 2 74, and the L-shaped rod 75 and the rubber head 76 are driven to move to the right, so that the rubber head 76 The rectangular frame 33 is hit. Since the slider 32 slides on the outer surface of the cross bar 31 and the extrusion rod 772 slides in the oil storage cylinder 771, the impact of the rubber head 76 can drive the rectangular frame 33 to slide to the right and squeeze the spring 773. When the limit rod 66 drives the rack 71 to move right, it will drive the L-shaped rod 75 to move to the left. At this time, the elastic force of the spring 773 will drive the rectangular frame 33 to reset. Therefore, the intermittent impact of the rubber head 76 will make the rectangular frame 33 shake left and right, and the internal crushing roller will shake together. The limit block 79 slides on the outer surface of the limit bar 78, so that the rack 2 74 can be limited, thereby improving the stability of the rack 2 74 when moving.

[0032] A further benefit of adopting the above method is that when the feeding mechanism 5 and the adjusting mechanism 6 drive the storage hopper 51 and the feeding pipe 52 to move, the rectangular frame 33 can also be vibrated synchronously. The vibration can help clean the accumulated materials on the surface of the crushing roller. Especially when the sand and gravel are excessively accumulated, the vibration can help loosen some of the sand and gravel from the crushing roller, reduce the accumulation of materials, and further prevent the excessive wear of the crushing teeth in the middle of the crushing roller.

[0033] Example 3, refer to Figure 1-Figure 8 A crushing and sand making device that can be produced according to different gradations includes a frame 1, a rectangular box 2 is arranged on the top of the frame 1, a cylinder 21 is fixed on the side of the rectangular box 2, a mounting shell 22 is fixed at one end of the extension rod of the cylinder 21, a circular block 23 is fixed in the mounting shell 22, a crushing box 3 is fixed on the top of the rectangular box 2, a cross bar 31 is fixed in the crushing box 3, a slider 32 is slid on the outer surface of the cross bar 31, a rectangular frame 33 is fixed between the sliders 32, a crushing mechanism is arranged in the rectangular frame 33, a filter hole 34 is opened at the bottom of the crushing box 3, the filter hole 34 is adapted to the size of the circular block 23, and a material drop port 4 is connected to the top of the crushing box 3, and also includes: A material discharge mechanism 5 is arranged on the top of the crushing box 3, and the material discharge mechanism 5 is used to discharge materials into the discharge opening 4; An adjusting mechanism 6 installed in the blanking opening 4, the adjusting mechanism 6 is used to adjust the position of the blanking mechanism 5; An impact mechanism 7 disposed on the crushing box 3, the impact mechanism 7 is used to vibrate the rectangular frame 33; A blocking mechanism 8 installed on the material discharging mechanism 5, the blocking mechanism 8 is used to make the sand and gravel in the material discharging mechanism 5 fall intermittently; An air blowing mechanism 9 is arranged in the crushing box 3 , and is used for blowing air into the rectangular frame 33 .

[0034] Furthermore, the blocking mechanism 8 includes a piston plate 81 that moves in the oil storage cylinder 771 , and the outer surface of the oil storage cylinder 771 is connected to an oil inlet pipe 82 .

[0035] Furthermore, the blocking mechanism 8 also includes a mounting block 80 fixed on the side of the moving bar 55, and a cylinder 83 is fixed to the side wall of the mounting block 80.

The left end of the extrusion rod 85 slides through the cylinder 83 and is fixed with a blocking block 87. The blocking block 87 is adapted to the size of the discharge pipe 52. A spring 86 is sleeved on the outer surface of the extrusion rod 85. The two ends of the spring 86 are respectively fixedly connected to the cylinder 83 and the piston disk 84, and the other end of the oil inlet pipe 82 is connected to the cylinder 83.

[0036] It should be noted that: the piston disc 1 81 is connected to the extrusion rod 1 772. When the rectangular frame 33 is hit by the rubber head 76 and drives the extrusion rod 1 772 to move to the right, the piston disc 1 81 will be synchronously driven to move to the right in the oil storage cylinder 771, and the oil in the oil storage cylinder 771 will be squeezed, so that the oil enters the oil inlet pipe 82, and then enters the cylinder 83 from the oil inlet pipe 82, and moves in the cylinder 83 through the piston disc 2 84. When the oil enters the cylinder 83, the piston disc 2 84 is squeezed by the oil and moves to the left, squeezing the spring 2 86. It is connected to the piston disc 2 84 through the extrusion rod 2 85, which will drive the extrusion rod 2 85 and the blocking block 87 to move to the left together, so that the blocking block 87 opens the bottom opening of the discharge pipe 52, so that the sand and gravel in the storage hopper 51 can fall down, and when the piston disc 1 81 moves to the left, the elastic force of the spring 2 86 will drive the blocking block 87 to reset.

[0037] A further advantage of adopting the above method is that when the impact mechanism 7 is running to vibrate the rectangular frame 33, the sand and gravel in the storage hopper 51 can also be synchronously made to intermittently fall onto the crushing roller, thereby avoiding too much material being discharged at one time, causing sand and gravel to accumulate on the crushing roller, and again preventing excessive wear of the crushing teeth in the middle of the crushing roller.

[0040] It should be noted that: the air inlet pipe 91 is connected to the cylinder 83. When the piston disc 84 is squeezed by the oil and moves to the left, the gas in the cylinder 83 will be squeezed, so that the gas enters the nozzle 92 through the air inlet pipe 91 and is sprayed from the nozzle 92 to the surface of the crushing roller.
