Description

Technical Field

[0001] The present invention relates to the technical field of sand making machines, and particularly to a silent sand making machine and its usage method. Background Art

[0002] Sand making machines are applicable to the crushing of soft or medium-hard and extremely hard ore materials with a hardness not higher than 320 Pa, and are widely used in many departments such as large-scale mining, smelting, building materials, highways, railways, water conservancy, and chemical industries.

[0003] In the current sand and gravel production industry, as a key equipment, sand making machines play a role in crushing various hard materials into sand materials of the required particle size. However, in the process of using existing sand making machines, there are generally problems of high noise and insufficient stability. These problems not only affect the operation efficiency and service life of the equipment, but also bring many disadvantages.

[0004] First of all, high noise is a major problem faced by existing sand making machines. Due to factors such as sand feeding and impact, sand making machines will generate strong noise during operation. This kind of noise will not only damage the hearing of operators, reduce their work efficiency, but also bring troubles to the lives of surrounding residents. And in the long run, this kind of noise pollution may also have a negative impact on the mental health of operators.

[0005] Secondly, the insufficient stability of sand making machines is also an urgent problem to be solved. Due to reasons such as equipment structure, manufacturing process, or improper installation, some sand making machines will show phenomena such as vibration and shaking during operation. This kind of instability will not only generate a large amount of noise, but also damage the sand making machines.

[0020] Further, as a preferred embodiment of the present invention, a damper is fixedly connected to the center of the bottom of the buffer plate, and the bottom of the damper is fixedly connected to the housing.

[0021] Further, as a preferred embodiment of the present invention, second limiting grooves are formed in both sides of the inner cavity of the housing. Second limiting blocks are slidably connected to the inner cavities of the second limiting grooves. One side of each second limiting block is fixedly connected to the spring piece.

[0022] In the present invention, a using method of a silent sand making machine includes the following steps:

[0023] Step 1: Start the electric telescopic rod. The extension of the output end of the electric telescopic rod drives the second fixed seat to move upward. This action triggers a series of chain reactions. The first rotating plate rotates around the intersection of the first rotating plate and the collar, thereby driving the connected second rotating plate to rotate. The rotation of the second rotating plate prompts the driving gear to rotate in the same direction. Since the driving gear meshes with the driven gear, the driven gear rotates accordingly, driving the first linkage plate and the second linkage plate to rotate successively. Under the combined action of this series of rotational movements, the two upper collars are driven to move upward to flexibly adapt to sand making machines of different heights, ensuring the stable installation of the equipment.

[0024] Step 2: Rotate one of the fixed plates. This action causes the threaded rod to start rotating. Since the threaded rod is threadedly connected to the collar, the threaded rod will move when rotating, thereby pushing the fixed plate closer to the sand making machine until they are in close contact. At the same time, when the threaded rod rotates, it drives the rotating gear to rotate under the action of the guide groove and the guide block. When the rotating gear rotates, it drives the toothed ring to rotate. When the toothed ring rotates, it drives the other three rotating gears to rotate, thus driving the other three fixed plates to fit the sand making machine synchronously, greatly enhancing the stability of the sand making machine and effectively avoiding vibrations and noises during operation.

[0025] Step 3: After pouring the sand and gravel into the inner cavity of the feed hopper, the sand and gravel enter the inner cavity of the conveying pipe. At this time, the sealing plate is in a downward state, forming a channel with the first guide plate to allow the sand and gravel to pass through, while the buffer assembly remains closed with the second guide plate to provide a buffer space for the sand and gravel. When the sand and gravel fall on the buffer plate, start the motor. The output shaft of the motor drives the eccentric disk to rotate. When the eccentric disk rotates, it pushes the second runner to move. When the second runner moves, it drives the second movable frame to rotate downward. The second movable frame drives the second round rod to rotate downward. At the same time, when the extrusion force of the eccentric disk on the first runner disappears, the first round rod drives the sealing plate to rotate under the action of the first spring to close the sand and gravel channel. At the same time, the first round rod drives the first movable frame to rotate. The first movable frame drives the sealing plate to rotate to fit the first guide plate. The first guide plate and the sealing plate do not allow the sand and gravel to flow through. When the first movable frame and the second movable frame rotate, they drive the first round rod and the second round rod to rotate respectively. The first round rod and the second round rod drive the first linkage frame and the second linkage frame to rotate respectively. When the first linkage frame and the second linkage frame rotate, they squeeze the telescopic rod, making the state of the telescopic rod shorter, and then squeezing the first spring to ensure the stable movement of the sealing plate and the buffer assembly. The states of the sealing plate and the buffer assembly are set in the opposite direction, effectively preventing the leakage of noise and dust.

[0026] Step 4: When the sand and gravel fall onto the top of the buffer plate, the buffer plate drives the connecting rod to move downward. The connecting rod drives the adjusting block to move downward and squeeze the wedge blocks on both sides. When the wedge blocks move, they drive the first limit block to slide in the inner cavity of the first limit groove, playing a role in limiting and guiding the wedge blocks. Then, when the wedge blocks move, they squeeze the second spring. Under the action of the elastic potential energy of the second spring, it plays a role in buffering the buffer plate for the first time. At the same time, when the connecting rod moves downward, it squeezes the third spring. Under the action of the elastic potential energy of the third spring, it plays a role in buffering the buffer plate for the second time. And when the buffer plate moves downward, it squeezes the spring piece to deform, which is used to assist in buffering the buffer plate. Finally, under the action of the damper, it is used to make the buffer plate tend to a stable state. By buffering the buffer plate, not only the impact noise of the sand and gravel on the equipment is reduced, but also the generation of noise can be effectively reduced. Finally, through the action of the muffler, the effective control of the noise in the sand and gravel processing process is realized.

[0027] Beneficial effects: The technical solution of the present application has the following technical effects: The present invention has the advantage of noise control.

[0028] The stable component and the strengthening component are set up, which together constitute a solid support system for the sand making machine. These components not only have a strong load-bearing capacity, but also can be flexibly adjusted according to the actual length of the sand making machine to ensure that the equipment can maintain the best stable state in any working condition, effectively improving the stability of the sand making machine, significantly reducing the noise generated by vibration and shaking, reducing the generation of noise from the source. At the same time, the stable support also extends the service life of the equipment and reduces the maintenance cost.

[0029] At the feeding port of the sand making machine, a blocking component is set up. This component includes two independent and complementary channels. The opening and closing states of these two channels are set in reverse, that is, when one channel is in the closed state, the other channel is in the open state, and vice versa. Using the principle of physical isolation, it effectively blocks the path of the noise generated when the sand and gravel enter the inner cavity of the sand making machine from spreading outward. At the same time, the blocking component also plays a role in dust prevention, avoiding the dust generated during the sand and gravel processing from spreading everywhere, thus protecting the health of the operators and maintaining a good working environment.

[0030] Furthermore, a perfect synergistic effect is formed between the blocking component and the buffer component. Before the sand and gravel enter the sand making machine, the buffer component first performs preliminary deceleration and buffering on it. This step not only helps to reduce the impact force of the sand and gravel on the equipment, reduce the generation of noise, but also improve the crushing efficiency and product quality of the sand making machine. And the blocking component plays a dual role at this time: on the one hand, it continues to block the spread of noise; on the other hand, it also provides a relatively closed space for the sand and gravel for further crushing treatment, thus ensuring the continuity and stability of the entire processing process.

[0059] In the present invention, a method for using a silent sand making machine comprises the following steps:

[0060] Step 1: Start the electric telescopic rod 39. The output end of the electric telescopic rod 39 extends to drive the fixed seat 2 310 to move upward. This action triggers a series of chain reactions. The rotating plate 1 32 will rotate with the intersection of the rotating plate 1 32 and the ring 31 as the axis point, thereby driving the rotating plate 2 33 connected thereto to rotate. The rotation of the rotating plate 2 33 prompts the driving gear 35 to rotate in the same direction. Since the driving gear 35 and the driven gear 36 are meshed, the driven gear 36 rotates accordingly, and drives the interlocking plate 1 34 and the interlocking plate 2 37 to rotate successively. Under the synergistic effect of this series of rotation actions, the two upper rings 31 are driven to move upward to flexibly adapt to sand making machines 2 of different heights to ensure the stable installation of the equipment.

[0061] Step 2: Rotate one of the fixed plates 45. This action causes the threaded rod 44 to start rotating. Since the threaded rod 44 and the collar 31 form a threaded connection, the threaded rod 44 will move when rotating, thereby pushing the fixed plate 45 closer to the sand making machine 2 until the two are tightly fitted. At the same time, the threaded rod 44 will drive the rotating gear 42 to rotate under the action of the guide groove 47 and the guide block 48. When the rotating gear 42 rotates, it will drive the gear ring 41 to rotate. When the gear ring 41 rotates, it will drive the other three rotating gears 42 to rotate, thereby driving the other three fixed plates 45 to synchronously fit toward the sand making machine 2, greatly enhancing the stability of the sand making machine 2 and effectively avoiding vibration and noise during operation.

[0062] Step 3: After pouring the sand and gravel into the inner cavity of the feeding hopper 7, the sand and gravel enter the inner cavity of the conveying pipe 5. At this time, the sealing plate 613 is in a downward state, forming a channel with the first guide plate 616 to allow the sand and gravel to pass through. While the buffer assembly 614 and the second guide plate 617 remain closed to provide a buffer space for the sand and gravel. When the sand and gravel fall on the buffer plate 6143, start the motor 61. The output shaft of the motor 61 drives the eccentric disk 62 to rotate. When the eccentric disk 62 rotates, it will push the second runner 68 to move. When the second runner 68 moves, it will drive the second movable frame 67 to rotate downward. The second movable frame 67 drives the second round rod 64 to rotate downward. At the same time, when the extrusion force of the eccentric disk 62 on the first runner 66 disappears, the first round rod 63 drives the sealing plate 613 to rotate under the action of the first spring 612 to close the sand and gravel channel. At the same time, the first round rod 63 drives the first movable frame 65 to rotate. The first movable frame 65 drives the sealing plate 613 to rotate and match with the first guide plate 616. The first guide plate 616 and the sealing plate 613 do not allow the sand and gravel to flow through. When the first movable frame 65 and the second movable frame 67 rotate, they drive the first round rod 63 and the second round rod 64 to rotate respectively. The first round rod 63 and the second round rod 64 drive the first linkage frame 69 and the second linkage frame 610 to rotate respectively. When the first linkage frame 69 and the second linkage frame 610 rotate, they will squeeze the telescopic rod 611, making the state of the telescopic rod 611 shorter, and then squeeze the first spring 612 to ensure the stable movement of the sealing plate 613 and the buffer assembly 614. The states of the sealing plate 613 and the buffer assembly 614 are arranged in the opposite direction, effectively preventing the leakage of noise and dust.

[0063] Step 4: When the sand and gravel fall on the top of the buffer plate 6143, the buffer plate 6143 will drive the connecting rod 61411 to move downward. The connecting rod 61411 drives the adjusting block 61413 to move downward and squeeze the wedge blocks 6147 on both sides. When the wedge blocks 6147 move, they will drive the first limiting block 6149 to slide in the inner cavity of the first limiting groove 6148, playing a role in limiting and guiding the wedge blocks 6147. Then, when the wedge blocks 6147 move, they will squeeze the second spring 6146. Under the action of the elastic potential energy of the second spring 6146, it plays a role in buffering the buffer plate 6143 once. At the same time, when the connecting rod 61411 moves downward, it will squeeze the third spring 61412. Under the action of the elastic potential energy of the third spring 61412, it plays a role in buffering the buffer plate 6143 twice. And when the buffer plate 6143 moves downward, it will squeeze the spring piece 6142 to deform, which is used to assist in buffering the buffer plate 6143. Finally, under the action of the damper 6144, it is used to make the buffer plate 6143 tend to a stable state. By buffering the buffer plate 6143, not only the impact noise of the sand and gravel on the equipment is reduced, but also the generation of noise can be effectively reduced. Finally, through the action of the muffler 615, the effective control of the noise during the sand and gravel processing process is realized.

9. A method for using a silent sand making machine, characterized in that: The method includes the following steps: Step 1: Start the electric telescopic rod (39). The extension of the output end of the electric telescopic rod (39) drives the second fixed seat (310) to move upward. This action triggers a series of chain reactions. The first rotating plate (32) rotates around the intersection of the first rotating plate (32) and the collar (31), thereby driving the connected second rotating plate (33) to rotate. The rotation of the second rotating plate (33) causes the driving gear (35) to rotate in the same direction. Since the driving gear (35) meshes with the driven gear (36), the driven gear (36) rotates accordingly, driving the first linkage plate (34) and the second linkage plate (37) to rotate successively. Under the combined action of this series of rotational movements, the two upper collars (31) are driven to move upward to flexibly adapt to sand making machines (2) of different heights, ensuring the stable installation of the equipment; Step 2: Rotate one of the fixed plates (45). This action causes the threaded rod (44) to start rotating. Since a threaded connection is formed between the threaded rod (44) and the collar (31), the threaded rod (44) will move when rotating, thereby pushing the fixed plate (45) closer to the sand making machine (2) until they are in close contact. At the same time, when the threaded rod (44) rotates, it drives the rotating gear (42) to rotate under the action of the guide groove (47) and the guide block (48). When the rotating gear (42) rotates, it drives the toothed ring (41) to rotate. When the toothed ring (41) rotates, it drives the other three rotating gears (42) to rotate, thereby driving the other three fixed plates (45) to fit the sand making machine (2) synchronously, greatly enhancing the stability of the sand making machine (2) and effectively avoiding vibrations and noises during the working process; Step 3: After pouring the sand and gravel into the inner cavity of the feeding hopper (7), the sand and gravel enter the inner cavity of the conveying pipe (5). At this time, the sealing plate (613) is in a downward state, forming a channel with the first guiding plate (616) to allow the sand and gravel to pass through. While the buffer assembly (614) and the second guiding plate (617) remain closed to provide a buffer space for the sand and gravel. When the sand and gravel fall on the buffer plate (6143), start the motor (61). The output shaft of the motor (61) drives the eccentric disk (62) to rotate. When the eccentric disk (62) rotates, it will push the second runner (68) to move. When the second runner (68) moves, it will drive the second movable frame (67) to rotate downward. The second movable frame (67) drives the second round bar (64) to rotate downward. At the same time, when the extrusion force of the eccentric disk (62) on the first runner (66) disappears, the first round bar (63) drives the sealing plate (613) to rotate under the action of the first spring (612) to close the sand and gravel channel. At the same time, the first round bar (63) drives the first movable frame (65) to rotate. The first movable frame (65) drives the sealing plate (613) to rotate and fit with the first guiding plate (616). The first guiding plate (616) and the sealing plate (613) do not allow the sand and gravel to flow through. When the first movable frame (65) and the second movable frame (67) rotate, they drive the first round bar (63) and the second round bar (64) to rotate respectively. The first round bar (63) and the second round bar (64) drive the first linkage frame (69) and the second linkage frame (610) to rotate respectively. When the first linkage frame (69) and the second linkage frame (610) rotate, they will squeeze the telescopic rod (611), making the state of the telescopic rod (611) shorter, and then squeeze the first spring (612) to ensure the smooth movement of the sealing plate (613) and the buffer assembly (614). The states of the sealing plate (613) and the buffer assembly (614) are set in the opposite direction, effectively preventing the leakage of noise and dust; Step 4: When the sand and gravel fall onto the top of the buffer plate (6143), the buffer plate (6143) drives the connecting rod (61411) to move downward. The connecting rod (61411) drives the adjusting block (61413) to move downward and squeeze the wedge blocks (6147) on both sides. When the wedge blocks (6147) move, they drive the first limiting block (6149) to slide in the inner cavity of the first limiting groove (6148), which plays a role in limiting and guiding the wedge blocks (6147). Then, when the wedge blocks (6147) move, they squeeze the second spring (6146). Under the action of the elastic potential energy of the second spring (6146), it plays a role in buffering the buffer plate (6143) once. At the same time, when the connecting rod (61411) moves downward, it squeezes the third spring (61412). Under the action of the elastic potential energy of the third spring (61412), it plays a role in buffering the buffer plate (6143) twice. And when the buffer plate (6143) moves downward, it squeezes the spring plate (6142) to deform, which is used to assist in buffering the buffer plate (6143). Finally, under the action of the damper (6144), it is used to make the buffer plate (6143) tend to a stable state. By buffering the buffer plate (6143), not only the impact noise of the sand and gravel on the equipment is reduced, but also the generation of noise can be effectively reduced. Finally, through the action of the muffler (615), the effective control of the noise in the sand and gravel processing process is realized.
