[0002] The raw materials are passed through the transmission device to be located in the barrel of the sand making machine, and then the barrel is driven to rotate by the transmission device. After the grinding medium is lifted to a certain height, the grinding medium can be thrown down at a certain linear speed under the gravity factor of the grinding medium itself. Under the action of force, the material is impacted, ground and squeezed, thereby achieving the effect of fine grinding and sand making.

For example, the grinding device for machine-made sand processing disclosed in the Chinese patent with authorization announcement number CN11 5430500B includes a base, and electric telescopic rods are fixedly provided at both ends of the left and right ends of the top surface of the base. The telescopic ends of the electric telescopic rods are fixedly connected to the support rods, and a support tube is rotatably sleeved on the support rods.

[0037] After research and analysis by the applicant, the reason for this problem (causing the sand making effect of the sand making machine to be poor) is that due to the difference in hardness and material of the raw materials added to the cylinder, when making sand, it is necessary to increase the number of grinding balls according to the actual grinding conditions or grinding time, and due to the nature of the grinding balls themselves, most of the grinding balls are reused; the grinding balls may collide with other materials or other grinding balls in the cylinder, which may cause damage, and if the damaged grinding balls are put into the cylinder again, the sand making effect of the sand making machine will be poor; in order to detect the grinding balls, the present invention transports the grinding media to the placement unit 8 through the transportation mechanism when performing the detection work, and then drives the telescopic part to move through the driving part, telescopic part, limit ring 74 and detector in the detection unit 7, so that the multiple scissor arms in the telescopic part are moved 73 opens, and can make the front ends of the two limit rings 74 on the telescopic part move forward until the two limit rings 74 abut, so that the scissor arm 73 and the limit ring 74 form a wrapping area, and then cooperate with the detector set on the scissor arm 73, so that the transportation mechanism is in the process of placing the grinding medium from the transportation mechanism to the rotating seat 83, and the detector can detect it, and then through the placement unit 8, the placement motor 84 drives the rotating block 85 to rotate, and the moving rotating block 85 can drive the driving block 86 to move, so that the driving block 86 moves in the U-shaped driving hole, and the moving driving block 86 applies a driving force to the rotating seat 83, so that the rotating seat 83 rotates around the rotating axis 82, and changes the detection area of ​​the detector on the grinding medium, which can detect grinding media with defects and remove such grinding media to avoid them from breaking in the cylinder and affecting the grinding effect of the sand making machine 1.

[0038] like Figure 1-Figure 8As shown, the device includes a placement unit 8 for placing abrasive media and capable of driving the abrasive media to rotate, and also includes a detection unit 7 composed of a driving part, a telescopic part, a limit ring 74 and a detector, and is used to detect the abrasive media located on the placement unit 8, a driving part for adjusting the telescopic distance at both ends of the telescopic part and connected to the telescopic part, two limit rings 74 symmetrically arranged on the telescopic part, and a plurality of detectors arranged on the telescopic part; when working, the two free ends of the telescopic part can move away from one end of the driving part through the movement of the driving part, because the two free ends of the telescopic part are respectively connected to the limit rings 74, and the limit rings 74 and the connecting rod in the telescopic part are both arc structures, so that the two limit rings 74 are abutted, and at this time, the annular structure formed by the telescopic part and the limit ring 74 is sleeved on the abrasive media, and the abrasive media can be detected by the set detector. When the abrasive media is placed on the placement unit 8, the detector can detect the bottom of the abrasive media to avoid the bottom of the abrasive media being blocked from the placement unit 8 after the abrasive media is placed on the placement unit 8, which makes it difficult for the detector to detect the bottom of the abrasive media.

[0039] The telescopic part includes a plurality of groups of movably connected scissor arms 73, and the scissor arms 73 include two movably connected arc-shaped connecting rods, wherein one of the scissor arms 73 connected to the output end of the driving part is connected to the output end of the driving part, and the other is sleeved on the output end of the driving part through a ball bearing, and the scissor arm 73 away from one end of the driving part is movably connected to a limit ring 74, and an arc-shaped waist hole is also provided on the limit ring 74, and a sliding block is provided on the scissor arm 73 located in the middle area, and the sliding block passes through the arc-shaped waist hole and slides in the arc-shaped waist hole; the driving part includes a bracket 71 arranged on the detection bracket 6, a detection seat 75 connected to the top of the bracket 71, and a detection seat 75 arranged on the detection seat 7 5, the output end of the driving motor 72 is connected to the telescopic part; when the detection work is needed, the driving motor 72 starts to work, and the moving driving motor 72 can drive the arc connecting rod connected to its output end to move, and the moving arc connecting rod can drive the arc connecting rod movably connected to it in another scissor arm 73 to start moving, and so on, the angle between the two arc connecting rods in the same scissor arm 73 can be adjusted, so that the scissor arm 73 at the front end can extend forward, and drive the limit ring 74 to move forward so that the front end of the limit ring 74 abuts, so that the scissor arm 73 and the limit ring 74 form a structure similar to the cover body, and cooperate with the detector to detect the abrasive medium located in the cover body.

[0040] The placement unit 8 includes a placement seat 81, a placement motor 84 fixedly mounted on the placement seat 81, a rotating shaft 82 movably connected to the placement seat 81, a rotating seat 83 connected to the rotating shaft 82, a rotating block 85 arranged at the output end of the placement motor 84, and a driving block 86 arranged on the rotating block 85; the rotating seat 83 is hemispherical, and is provided with semicircular through holes, and U-shaped driving holes are provided between adjacent semicircular through holes; after the detector completes the first detection of the abrasive medium located on the placement seat 81, the placement motor 84 starts to work at this time, and the moving placement motor 84 can drive the rotating block 85 to rotate, and then drive the driving block 86 to rotate, so that the driving block 86 can move in the U-shaped driving hole on the rotating seat 83, and apply a driving force to the rotating seat 83 during the movement, so that the rotating seat 83 can rotate around the rotating shaft 82, and then adjust the detection area of ​​each detector on the abrasive medium to avoid damage to the detector or stains on some detector lenses, which may cause errors in the detection results.

[0041] The device also includes a mounting seat 2 and a sand making machine 1 body, a weighing part 5 arranged on the mounting seat 2, a feeding mechanism 3 and a transporting mechanism 4 symmetrically arranged in the radial direction of the weighing part 5, a detection bracket 6 fixedly connected to the mounting seat 2, a conveying mechanism 10 arranged on the detection bracket 6, a discharge unit 9 arranged on the mounting seat 2, a discharge bin 11 connected to the discharge unit 9, a discharge pipe 13 connected to the discharge unit 9, and a feed pipe 12 arranged at the feed end of the sand making machine 1; the discharge pipe 13 is located above the feed pipe 12; the conveying mechanism 10, the feeding mechanism 3 and the transporting mechanism 4 have the same structure; the detection unit 7 and the placement unit 8 are located on the detection bracket 6; a plurality of partitions are arranged on the discharge bin 11 to form a plurality of discharge areas; the weighing part 5 is a prior art, which can weigh the grinding medium, and according to the weighing result, the grinding media of different weights are placed in different discharge areas, and the grinding media of the same weight are placed in the same discharge area.

[0042] In a further embodiment, during operation, the grinding medium is placed on the weighing seat through the feeding mechanism 3, and the weighing part 5 performs weight detection on the grinding medium. When the detected weight is less than the preset value, it indicates that the grinding medium is damaged. At this time, the transportation mechanism 4 removes it. When its weight meets the standard, the transportation mechanism 4 can adjust the height of the grinding medium and place it on the placement unit 8, and detect the grinding medium through the detection unit 7. Then, according to the detection result, the grinding medium that does not meet the established standard is removed by the conveying mechanism 10, and for the grinding medium that meets the standard, it is placed in different placement areas according to the size and size of the grinding medium. Then, according to the actual ratio requirements or the grinding conditions of the material, the corresponding number of grinding media is selected, and the corresponding number of grinding balls is put into the feed pipe 12 through the unloading unit 9, so that the grinding medium can enter the sand making machine 1 along the feed pipe 12. During the movement of the sand making machine 1, the grinding medium collides with the quartz stone to complete the sand making work of the quartz stone.

[0043] The feeding mechanism 3 includes a first cylinder 31 and a first slide rail 34 fixedly arranged on the mounting seat 2, a moving block 32 connected to the output end of the first cylinder 31, a first slider 33 arranged on the moving block 32 and slidably connected to the first slide rail 34, a second cylinder 35 is also arranged on the moving block 32, a lifting block 36 connected to the output end of the second cylinder 35, a rotating part 37 arranged on the lifting block 36, and a manipulator 38 connected to the rotating part 37; when it is necessary to feed the grinding medium, the first cylinder 31 is connected to the output end of the first cylinder 31, and the first slider 33 is arranged on the moving block 32 and slidably connected to the first slide rail 34. The cylinder 31 starts to work, and with the cooperation of the first slider 33, the manipulator 38 can clamp the grinding medium at a predetermined position, and then the first cylinder 31 works in the reverse direction to place the clamped grinding medium on the weighing seat. At the same time, the grinding medium is divided into three categories, namely large grinding balls, medium grinding balls and small grinding balls according to their sizes. In order to ensure that the feeding mechanism 3 can clamp grinding balls of different sizes, the second cylinder 35 is further arranged to adjust the height of the manipulator 38 so that it can grab and carry grinding media of different sizes.

[0044] The unloading unit 9 includes a baffle plate 93 provided at the outlet end of the unloading area and movably connected to the partition, a transverse movement component 91 provided on the mounting seat 2 for adjusting the position of the unloading bin 11 in the plane where the mounting seat 2 is located, a unloading component 92 provided on the mounting seat 2 for making the baffle plate 93 and the partition relatively movable, and a counting sensor 94 provided on the unloading component 92; after completing the detection work, grinding balls of similar sizes are placed in the corresponding unloading area according to the size of the grinding media, and then the operator calculates the number of grinding media of each size that needs to be added according to the proportion of the existing grinding media in the sand making machine 1, and then through the movement of the transverse movement component 91, grinding media of different sizes and quantities can be added thereto and counted by the counting sensor 94, so that the proportion of the grinding media in the sand making machine 1 can be adjusted to improve its grinding efficiency. At the same time, in the process of adding grinding media, the conveying mechanism 10 can still place the grinding media that meets the standards in the same unloading area on the unloading bin 11. The placement area at this time is different from the unloading area where unloading work is being performed.

[0045] The transverse movement assembly 91 includes a transverse movement rail 917, a transverse movement motor 911 and a support 912 arranged on the mounting seat 2, a transverse movement screw rod 913 arranged on the support 912, a transmission wheel 915 respectively arranged on the transverse movement motor 911 and one end of the transverse movement screw rod 913, a transmission belt 916 for connecting the two transmission wheels 915, a connecting block 914 sleeved on the transverse movement screw rod 913, and a transverse movement slider 918 arranged on the lower bin 11 and slidably connected to the transverse movement rail 917; the connecting block 914 is connected to the lower bin 11; according to the preset ratio of each small ball, The operator calculates the number of large, medium and small grinding balls that need to be added, and then the transverse motor 911 starts working. Through the transmission wheel 915 and the transmission belt 916, the transverse screw 913 can be rotated, and the rotating transverse screw 913 can drive the connecting block 914 to move, so that the connecting block 914 can drive the lower bin 11 to move in the length direction of the transverse slide rail 917, so that grinding media of different sizes can be selected for addition as needed, and the counting sensor 94 can be set to ensure the addition quantity, so that the ratio between the added large, medium and small grinding balls can meet the set value.

[0046] The unloading assembly 92 includes a unloading seat 921 arranged on the mounting seat 2, a unloading cylinder 922 fixedly connected to the unloading seat 921, a driving member 923 arranged at the output end of the unloading cylinder 922, and an electromagnet 924 connected to the driving member 923; the baffle plate 93 is a magnetic structure; when unloading, the coil on the electromagnet 924 is energized and the position of the electromagnet 924 is adjusted by the unloading cylinder 922, so that the baffle plate 93 can be attracted and the baffle plate 93 can slide on the partition, so that the grinding balls can fall into the discharge pipe 13, and the grinding balls enter the feed pipe 12 along the discharge pipe 13 and enter the sand making machine 1 along with the raw materials in the feed pipe 12. By turning on the sand making machine 1, grinding media of different sizes can crush the quartz stone to complete the sand making work.

[0047] The grinding medium is a grinding ball, which is made of a material with strong wear resistance. At the same time, a carburizing and quenching treatment is performed on the surface of the grinding ball to form a protective layer on the surface.

[0048] The surface of the grinding ball is provided with a concave-convex structure, and the interior thereof is provided with a hollow or porous structure; the concave-convex surface enables the grinding ball to increase the contact area and friction between it and the material, and at the same time, when it falls, the convex points formed by the concave-convex surface can apply a greater pressure to the material, which is convenient for improving the grinding efficiency of the grinding ball, and the hollow or porous structure can reduce the weight of the grinding ball, reduce energy consumption, and produce a certain buffering effect during the grinding process, reducing energy loss during collision.

[0049] In a further embodiment, since the grinding balls are located in the cylinder of the sand making machine 1 and move with the rotation of the cylinder when the sand making machine 1 is used, after the grinding balls are transported to a predetermined position, they collide with the material in the cylinder under the influence of their own gravity to reduce the volume of the material. In this process, certain requirements are placed on the wear resistance of the grinding balls. Therefore, when manufacturing the grinding balls used in the present device, special treatments are performed on the surface of the raw material of the grinding balls, i.e., high chromium alloy steel, such as carburizing quenching, nitriding, etc., to form a hard protective layer, thereby extending the service life of the sand balls. At the same time, in order to improve the grinding efficiency of the grinding balls, the grinding balls are designed to be spherical structures to ensure that they can be evenly distributed and effectively collide in the sand grinder.

[0050] Working principle: When the grinding medium needs to be fed, the first cylinder 31 starts to work. With the cooperation of the first slider 33, the manipulator 38 can clamp the grinding medium at a predetermined position. Then the first cylinder 31 works in the reverse direction to place the clamped grinding medium on the weighing seat. The grinding medium is divided into three categories according to its size, namely large grinding balls, medium grinding balls and small grinding balls. In order to ensure that the feeding mechanism 3 can clamp grinding balls of different sizes, the second cylinder 35 is set to adjust the height of the manipulator 38 so that it can clamp grinding media of different sizes. Grab and carry work; when the grinding medium is on the weighing seat, the weighing unit 5 weighs it. When the detected weight is less than the preset value, it means that the grinding medium is damaged. At this time, the transportation mechanism 4 removes it. When its weight meets the standard, the transportation mechanism 4 can adjust the height of the grinding medium and place it on the placement unit 8, and the grinding medium is tested by the detection unit 7; when the detection work is performed, the drive motor 72 starts to work, and the moving drive motor 72 can drive the arc connecting rod connected to its output end to move, and the moving arc connecting rod can drive another scissor arm 73 connected to it. The movable arc connecting rod starts to move, and so on, so that the angle between the two arc connecting rods in the same scissor arm 73 can be adjusted, so that the scissor arm 73 at the front end can extend forward, and drive the limit ring 74 to move forward so that the front end of the limit ring 74 abuts, so that the scissor arm 73 and the limit ring 74 form a structure similar to a cover body, and cooperate with the detector to detect the abrasive medium located in the cover body; after the detector completes the first detection of the abrasive medium located on the placement seat 81, the placement motor 84 starts to work at this time, and the moving placement motor 84 can drive the rotating block 85 to rotate, which can drive The driving block 86 rotates so that the driving block 86 can move in the U-shaped driving hole on the rotating seat 83, and applies driving force to the rotating seat 83 during the movement, so that the rotating seat 83 can rotate around the rotating shaft 82, thereby adjusting the detection area of ​​each detector on the abrasive medium to avoid damage to the detector or stains on some detector lenses, which may cause errors in the detection results; then, according to the detection results, the abrasive media that do not meet the established standards are removed by the conveying mechanism 10, and the abrasive media that meet the standards are placed in different placement areas according to the size of the abrasive media;Then the operator calculates the amount of grinding media of each size that needs to be added according to the ratio of the existing grinding media in the sand making machine 1, and then through the movement of the transverse movement component 91, grinding media of different sizes and quantities can be added thereto and counted by the counting sensor 94, so that the ratio of the grinding media in the sand making machine 1 can be adjusted to improve its grinding efficiency. At the same time, in the process of adding grinding media, the conveying mechanism 10 can still place the grinding media that meets the standards in the corresponding unloading area on the unloading bin 11. The placement area at this time is different from the unloading area where unloading work is being carried out; during the unloading process, according to the pre-set ratio of each small ball, the operator calculates the number of large, medium and small grinding balls that need to be added, and then the transverse movement motor 911 starts working, and the transverse movement screw 913 can be rotated through the set transmission wheel 915 and transmission belt 916, and the rotation The transverse screw rod 913 can drive the connecting block 914 to move, so that the connecting block 914 can drive the unloading bin 11 to move in the length direction of the transverse slide rail 917, so that grinding media of different sizes can be selected for addition according to needs, and the counting sensor 94 can ensure the addition quantity, so that the ratio between the added large, medium and small grinding balls can meet the set value; when unloading, the coil on the electromagnet 924 is energized, and the position of the electromagnet 924 is adjusted by the unloading cylinder 922, so that it can attract the baffle plate 93, so that the baffle plate 93 slides on the partition, and then the grinding balls can fall into the discharge pipe 13, and the grinding balls enter the feed pipe 12 along the discharge pipe 13 and enter the sand making machine 1 along with the raw materials in the feed pipe 12. By turning on the sand making machine 1, grinding media of different sizes can crush the quartz stone to complete the sand making work. ;
