Description

Technical Field

[0001] The invention relates to the technical field of quartz stone crushing, in particular to a quartz sand making machine. Background Art

[0002] The working principle of the quartz sand making machine mainly involves the crushing methods of "stone against stone" and "stone against iron". The equipment drives the belt and pulley through the motor, and then drives the eccentric shaft to make the movable jaw move up and down. When the movable jaw rises, the angle between the toggle plate and the movable jaw becomes larger, pushing the movable jaw plate close to the fixed jaw plate, and the material is crushed or split; when the movable jaw descends, the angle between the toggle plate and the movable jaw becomes smaller, and the movable jaw plate leaves the fixed jaw plate under the action of the pull rod and spring. At this time, the crushed material is discharged from the lower opening of the crushing chamber. During the whole process, the material is subjected to multiple impacts, friction and grinding in the vortex crushing chamber to achieve a fine crushing effect.

[0003] However, there are still some problems with the existing sand making machines. For example, a patent application with publication number CN113351352A discloses an intelligent detection and alarm device for the wear degree of a sand making machine, which records a sand making machine body, a distribution cone arranged at the center of the sand making machine body, including a cover body arranged at the upper end of the sand making machine body, the upper end of the cover body is connected to a distance measuring sensor through a support, the distance measuring sensor is connected to a controller of the sand making machine body, and a monitoring unit for judging the wear degree of the distribution cone is provided in the controller.

[0004] However, there are still some problems in the above patent application. Since the rangefinder in the above patent application is fixedly installed on the crusher casing, when it is necessary to add quartz stone raw materials to the crusher or discharge processed quartz sand, the raw materials or products will damage the rangefinder, which may easily cause damage to it. At the same time, there is a limitation in the patent application. The patent application can only be applied to the detection of the position of the impact plate of the crusher when it is not working. In the working state, the quartz stone is located between the impact plate and the hammer. Not only is there a possibility of collision between the quartz stone and the rangefinder, but there is also a problem that the rangefinder cannot perform wear measurement due to the obstruction of the quartz stone.

DETAILED DESCRIPTION

[0054] After research and analysis by the applicant, the reason for this problem (the distance meter cannot perform wear measurement when in working state) is that, in the prior art, when it is necessary to add quartz raw materials to the crusher or discharge processed quartz sand, the raw materials or products will damage the distance meter, which is easy to cause damage to it; the present invention provides a distance measuring component 5 and a screening component 8, so that the distance meter can convert the measured information into digital information, and the operator can observe the displayed digital information and compare it with the preset value, so as to judge the degree of wear of the device, and then adjust the position of the impact plate 6 or replace the plate hammer 3, and then when the device is in a non-working state, the wear of the impact plate 6 or the plate hammer 3 can be detected, and the plate hammer 3 with a larger amount of wear can be replaced or the position of the impact plate 6 can be adjusted, so as to reduce the distance between the impact plate 6 and the plate hammer 3, so as to avoid the failure of the quartz sand making work caused by the size of the processed quartz sand being larger than the preset quartz sand size. Through the transmission component 7, the larger quartz sand can be screened out and then transported to the screening component 8, so that the quartz sand can be classified according to size. According to the classification, when the size exceeds the preset size, it means that in the sand making process of the sand making machine, the hardness of the quartz stone is too large or the size is too large, causing the wear of the plate hammer 3 or the impact plate 6, which in turn causes the size of the quartz sand after sand making to exceed the predetermined size, so that the size of the produced quartz sand does not meet the established standards, indicating that the device has a large amount of wear during the working process. At this time, the staff needs to stop the rotation of the drive motor, stop the sand making machine, and inspect and repair the plate hammer 3 or the impact plate 6. Through the coordinated use of the set ranging component 5 and the screening component 8, the wear of the sand making machine can be monitored before and after the sand making machine works and during the working process of the sand making machine, so as to avoid excessive wear and tear, which will lead to a large amount of quartz sand that does not meet the established size, reduce the number of rework of the quartz sand, and ensure the smooth progress of the sand making work.

[0055] The present invention discloses a quartz sand making machine, see Figure 1-Figure 11, comprising a crusher 1, a distance measuring assembly 5 arranged at the discharge port end of the crusher body 1, the distance measuring assembly 5 comprising a mounting plate 51, a driving unit, a clamping portion 52 and a distance meter, the mounting plate 51 being arranged at the discharge port end of the crusher body 1, the driving unit being arranged on the mounting plate 51, the clamping portion 52 being arranged on the mounting plate 51 and clamping the distance meter; a rotor 2 being arranged on the crusher body 1, and a plurality of plate hammers 3 being arranged on the curved surface of the rotor 2, the rotor 2 rotating so that the quartz stone collides with the rotor 2 or the plate hammer 3, so that the quartz stone after the collision collides with the quartz stone falling from the crusher body 1 or the inner wall of the crusher body 1, so that the quartz stone The stone is crushed to form quartz sand; there are two adjusting mechanisms 4, which are sleeved on the rotor 2 and connected to the crusher body 1, located at both ends of the plate hammer 3, and a plurality of impact plates 6 are arranged on the adjusting mechanism 4. The distance between the impact plate 6 and the axis of the rotor 2 is adjusted by the adjusting mechanism 4 to change the flying distance of the quartz stone before it hits the impact plate 6, so that the quartz stone is crushed; the transmission component 7 is located below the distance measuring component 5, and is used to receive the quartz sand falling from the discharge port end of the crusher body 1 and perform initial screening on it; the screening component 8 is connected to the transmission component 7, and is used to receive the quartz sand whose size does not meet the requirements when the transmission component 7 is screened, and classify this type of quartz sand.

[0056] In a further embodiment, the crusher 1 body also includes a driving mechanism, which includes a driving motor, a first driving wheel arranged at the output end of the driving motor, and a second driving wheel arranged at one end of the rotor 2, and a driving belt for connecting the first driving wheel and the second driving wheel. Through the provided driving motor and driving belt, when the driving motor is working, the rotor 2 located in the crusher 1 body can be rotated, and the plate hammer 3 on the circumference of the rotor 2 can also be driven to start rotating, so that the quartz stone can collide with the plate hammer 3, and the quartz stone after the collision collides with the quartz stone falling from the feed port of the crusher 1, or directly collides with the impact plate 6. Under the action of force, the quartz stone is broken, and the broken quartz stone can collide multiple times in the crusher 1, so that the produced quartz sand meets the established standards.

[0057] In a further embodiment, the rangefinder in the present invention is a prior art, which can convert the measured information into digital information. The operator can observe the displayed digital information and compare it with the preset value to determine the degree of wear of the quartz sand making machine, and then adjust the position of the impact plate 6 or replace the plate hammer 3. When the quartz sand making machine is in a non-working state, the wear of the impact plate 6 or the plate hammer 3 can be detected, and the plate hammer 3 with larger wear can be replaced or the position of the impact plate 6 can be adjusted to reduce the distance between the impact plate 6 and the plate hammer 3, so as to avoid the size of the processed quartz sand being larger than the preset quartz sand size, thereby causing the failure of the quartz sand making work. Through the set transmission component 7, quartz sand with larger size can be screened out and then transported to the screening component 8, so that the quartz sand can be sorted according to the size. The sand making machine is operated by a plurality of operators, and the plurality of operators are connected to the plurality of sand making machines. The plurality of operators are connected to the plurality of sand making machines, and the plurality of operators are connected to the plurality of sand making machines. The plurality of operators are connected to the plurality of sand making machines, and the plurality of operators are connected to the plurality of sand making machines. The plurality of operators are connected to the plurality of sand making machines, and the plurality of operators are connected to the plurality of sand making machines.

[0058] In a further embodiment, a conventional distance meter is installed at a predetermined position on the shell of the crusher 1. Since its position is fixed, no matter whether it is located at the feed port or the discharge port during detection, during the process of adding or discharging materials, a collision may occur between the quartz stone or quartz sand and the distance meter, which may easily cause damage to the quartz stone. In addition, there are relatively few existing distance meters. During the detection process, due to obstruction of the device or other factors, there is no comparison between the data, which results in too little data, resulting in inaccurate data obtained, and thus inaccurate measurement results.

[0059] In order to solve the above problems, the driving unit includes two driving cylinders 53 symmetrically arranged on the mounting plate 51, a driving slider 54 connected to the output end of the driving cylinder 53, and a driving ring 55 for connecting the two driving sliders 54; the driving ring 55 abuts against the clamping portion 52; a through hole is opened on the mounting plate 51, and the manufactured quartz sand falls below through the through hole; when the crusher 1 is in working state, the driving cylinder 53 works, so that the driving ring 55 can be located above the discharge port of the crusher 1, thereby reducing the damage of the falling quartz sand to the distance measuring component 5; when measurement work is required, the driving cylinder 53 starts to work, and the moving driving cylinder 53 can drive the driving slider 54 to move, thereby changing the distance between the driving ring 55 and the mounting plate 51. The straight-line distance between them can drive the clamping part 52 to move, thereby changing the clamping area between the two clamping blocks 528. By placing the rangefinder in the clamping area and adjusting the size of the clamping area, the clamping limit work of the rangefinder is completed, and the installation of the rangefinder is completed. When the crusher 1 is working, the range of the clamping area can be increased, and the disassembly of the rangefinder can be completed, thereby avoiding damage to the rangefinder caused by the quartz stone during the operation of the crusher 1. At the same time, the distance measuring component 5 is installed at the discharge port of the crusher 1 in an annular structure. During the detection process, multiple sets of data can be provided, which can not only avoid the failure of data collection due to obstruction by objects or other devices, but also can compare and screen multiple sets of data, thereby ensuring the accuracy of the collected data.

[0060] In a further embodiment, the clamping portion 52 includes two rotating shafts 525 and an articulated seat 522 provided on the mounting plate 51, a driving rod 523 movably connected to the articulated seat 522, a driving wheel 521 provided at one end of the driving rod 523, a driven wheel 524 provided at the other end of the driving rod 523, a driving block 526 provided on the rotating shaft 525, a connecting block 529 provided on the driving block 526, a connecting rod 5210 provided on the connecting block 529, and a connecting rod 5211 provided on the connecting block 529. The clamping block 528 at the free end of the rod 5210; the driving block 526 includes a first driving block and a second driving block. Of the two rotating shafts 525, the first driving block is connected to the rotating shaft 525 away from the driving rod 523, and the other is the second driving block. The clamping portion 52 also includes a connecting shaft 5211 for connecting the two driving blocks 526, and a slider 527 arranged on the connecting shaft 5211. The first driving block is provided with a slide groove adapted to the slider 527, and the slider 527 is located in the slide groove. The driven wheel 524 is in contact with the second driving block; when the rangefinder needs to be installed, the distance between the driving ring 55 and the mounting plate 51 can be adjusted by driving the cylinder 53, so that the driving ring 55 drives the driving wheel 521 to move close to the mounting plate 51, and the driven wheel 524 is moved by the movable connection between the driving rod 523 and the hinge seat 522, so that the second driving block can be pushed to move, and the moving second driving block drives the connecting block 529 and the connecting shaft 5211 connected thereto to move, and the moving connecting shaft 5211 drives the driven wheel 524 to move. The movable slider 527 moves in the slide groove on the first driving block, and then can drive the connecting block 529 connected to the first driving block to move, so that the rotating shaft 525 can move, and then can drive the clamping block 528 to move, and adjust the area between the two clamping blocks 528. When the operator places the rangefinder between the two clamping blocks 528, the clamping block 528 can complete the clamping and limiting work of the rangefinder, and then complete the installation of the rangefinder, ensuring that the rangefinder can measure the impact plate 6 or the hammer 3.

[0061] In a further embodiment, since a plurality of clamping parts 52 are provided in the present invention, and the driving method of the clamping parts 52 is to use the driving cylinder 53 to drive the driving ring 55 to move, the position of the driving ring 55 in the axial direction of the mounting plate 51 is adjusted, and the installation and disassembly of the rangefinder is completed. During this process, each clamping part 52 is opened or clamped at the same time. When one or two rangefinders are damaged and need to be replaced, the above-mentioned driving method will cause all the rangefinders to be disassembled, which may easily cause the rangefinder to fall or require multiple workers to install the rangefinder, resulting in a waste of labor resources.

[0062] In order to solve the above problems, the mounting plate 51 of the present invention also includes a rotating motor, a driving gear disposed at the output end of the rotating motor, and a gear ring meshing with the driving gear and disposed on the inner wall of the driving ring 55; an annular groove is also provided on the inner wall of the driving ring 55, and the driving slider 54 is located in the annular groove and is slidably connected to the annular groove; the annular groove is located above the gear ring, and when the driving cylinder 53 is working, the driving slider 54 can drive the driving ring 55 to move in its axial direction, and when the rotating motor is working, the driving slider 54 can make an orbital motion on the driving ring 55 and along the axis of the driving ring 55; The driving ring 55 is also provided with a groove area. The driving wheel 521 located in the area can adjust the spacing between the clamping blocks 528 under the cooperation of the driving rod 523 and the driving slider 54, so that the damaged rangefinder can be replaced; the axial length of the gear ring is smaller than the axial length of the driving gear, and the gear ring can be driven by the driving cylinder 53 to reciprocate in the axial direction of the driving gear; in order to be able to replace the damaged rangefinder in a targeted manner, a groove area is provided on the driving ring 55 of the present invention. When replacement work is required, the rotating motor starts to work, and the moving rotating motor can drive The driving gear at the output end rotates, and the moving driving gear can drive the gear ring to move. Since the gear ring is installed on the inner wall of the driving ring 55, it can drive the driving ring 55 to rotate. At this time, the driving slider 54 can slide in the slide groove. During the rotation of the driving ring 55, the position of the groove area is constantly changed so that it is located at the position of the driving wheel 521 in the clamping part 52 corresponding to the rangefinder to be replaced. Since the position of the groove area is lower than that of other areas, the driving wheel 521 located in this area is higher than the driving wheels 521 located in other areas, so that the clamping part 52 in the clamping part 52 located in this area is The distance between block 528 increases, so that the corresponding distance meter can be replaced. After the replacement is completed, the rotating motor rotates, and the driving wheel 521 is away from the groove area, so that the damaged distance meter in the distance measuring component 5 can be replaced. At the same time, the replacement work can be carried out in a targeted manner, so as to avoid the normally working distance meter from falling from the clamping part 52, thereby ensuring the normal operation of the distance meter, detecting the distance from the preset detection point of the impact plate 6 or the plate hammer 3 to the rangefinder, reflecting the wear condition of the impact plate 6 or the plate hammer 3, replacing the plate hammer 3 or adjusting the position of the impact plate 6 according to the detection result, and avoiding the quartz stone that does not meet the specifications from being discharged from the discharge port.

[0063] The transmission assembly 7 includes a bracket 73 connected to the crusher 1, a screen 71 arranged on the bracket 73, a limit frame 72 connected to the screen 71, a belt conveyor 74 located at the bottom of the limit frame 72, at least two screens arranged in the screen 71, and a discharge plate 75 arranged at the discharge end of the screen 71; the two screens are at a predetermined angle to the ground, and the screen holes on the two screens have different diameters. The screen hole diameter of the screen close to the belt conveyor 74 is smaller than the screen hole diameter of the other screen, so that quartz stones larger than the screen hole diameter can be screened and excluded from the discharge plate 75, while the quartz sand that meets the standards falls onto the belt conveyor 74 and is transported to The quartz sand falls into the belt conveyor 74 and is transported to the predetermined position. The quartz sand that meets the standard size and the quartz sand that does not meet the standard can be quickly screened out through the two screens, and the quartz sand that meets the standard size and the quartz sand that does not meet the standard can be classified and transported. At the same time, the strength of the screen located above is greater than the strength of the screen located below, so as to prevent the quartz stone with larger mass from damaging the filter. When working, the quartz sand falls into the sieving machine 71, and the sieving machine 71 screens the quartz sand according to the size. The quartz sand that meets the size falls onto the belt conveyor 74 and is transported to the predetermined position along with the belt conveyor 74.
