Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of stone block cutting equipment, and in particular relates to a cutting equipment for large stone block segmentation based on building aggregate production. BACKGROUND

[0002] In the building block manufacturing industry, the quality and supply efficiency of building aggregates have a significant impact on the entire production process. Large stone blocks, as an important source of building aggregates, need to be segmented before actual use. Traditional stone block segmentation methods, such as manual hammering and breaking or small and simple cutting equipment operation, have obvious drawbacks. Manual operation not only has high labor intensity and extremely low efficiency, but also has difficulty in controlling segmentation accuracy, resulting in inconsistent sizes of the output aggregates, which affects the forming quality of subsequent building blocks. The cutting capacity of small equipment is limited, and it is difficult to handle large stone blocks, which cannot meet the needs of large-scale production. With the rapid development of the construction industry, the quality and output of building blocks are continuously improving.

[0003] In the patent with the patent number CN114953212A, a cutting equipment for ore processing is disclosed. The structure includes a cutting mechanism, an operation table, a support frame, and a base. The operation table is movably engaged with the upper surface of the support frame, the bottom of the support frame is welded to the top of the base, the cutting mechanism is connected to the inside of the operation table and the upper surface of the support frame, and the sharp corner stone is squeezed between the two clamping strips. The two clamping strips can clamp the sharp corner stone, and the blocking groove can reduce the speed of the sharp corner stone sliding out of the two clamping strips, thereby buffering the rebound force of the sharp corner stone after hitting the inner wall of the impact shield. The reset strip can push the transition block back along the ring after the reducing touch groove stops rotating, and the inner recess can grab the earth attached between the ore cutting surface and the blade when the movable block is reset, so that the ore can be quickly separated from the blade after cutting.

[0004] The existing technology has the following defects:

[0005] Single cutting method: the existing cutting equipment uses a rope saw for large irregular stone blocks and a saw blade for small regular stone blocks. Frequent equipment replacement is required when facing different specifications of stone blocks, which not only consumes manpower and time, reduces production efficiency, but also limits the application range of the equipment. Therefore, it is necessary to set a structure that can adjust the cutting method to avoid the inconvenience of replacing equipment, save manpower and time, make the production process smoother, accurately adapt to various stone blocks, and thus improve the overall production efficiency and stone block processing quality.

[0006] The efficiency is low when cutting large irregular stone blocks: large irregular stone blocks have various shapes, uneven surfaces and protruding corners, lack of regular planes and uniform shapes, which makes it difficult for cutting equipment to find a stable and suitable cutting point and cutting path. Moreover, the power and cutting capacity of the wire saw are limited, which makes it difficult to provide sufficient cutting force, so the cutting process is very slow. Therefore, a saw blade slotting structure is needed before cutting large irregular stone blocks to provide a stable and suitable cutting point and cutting path for subsequent wire saw cutting, effectively avoiding cutting difficulties caused by irregular stone shapes. At the same time, slotting can reduce the resistance of wire saw cutting to some extent, make up for the insufficient power and cutting capacity of the wire saw, speed up the cutting process, reduce the pause and adjustment during cutting, and thus significantly improve the overall cutting efficiency.

[0045] When the stone block to be cut is a regular stone block such as a cube or a cuboid, the saw blade cutting mechanism 2 and the wire saw cutting mechanism 3 are used, the diamond saw blade 243 is moved to a suitable cutting position by sliding the horizontal moving frame 223 on the fixed horizontal rod 222, and the rotating assembly 24 is started to cut the stone block, when the height of the stone block is less than or equal to the cutting height of the diamond saw blade 243, the stone block can be directly cut; when the height of the stone block is greater than the cutting height of the diamond saw blade 243, the limiting rods 235 at the bottom of the protective cover 231 contact the surface of the stone block, thereby preventing the diamond saw blade 243 from being excessively pressed downward and damaged, at this time, the diamond saw blade 243 cannot be cut downward, but can be cut horizontally, and then the wire saw cutting is converted, when the wire saw is cut, the upper arc groove 233 in the tensioning frame 232 can drive the square diamond wire saw 33 to move upward, thereby being adjusted.

[0049] With reference to Figures 8-10 The movable assembly 34 comprises two movable support frames 341 fixedly connected to the inner wall of the gantry 1, and the inner wall of each movable support frame 341 is slidingly connected with a movable trolley 343.

[0050] The wire saw cutting mechanism 3 is arranged, and the diamond wire saw 33 is designed in a ring shape. When the upper arc groove 233 in the tensioning frame 232 drives the upper diamond wire saw 33 to move upward, the tension change of the ring-shaped wire saw causes the movable wheel 342 to be pulled downward by the lower diamond wire saw 33, so that the lower diamond wire saw 33 is embedded in the cutting groove reserved by the previous saw blade cutting and provides tension. Then, the stepping motor 31 drives the driving wheel 32 to rotate, the driving wheel 32 drives the diamond wire saw 33 through the clamping grooves, and the diamond wire saw 33 is sequentially cut around the first fixed wheel 35, the two second fixed wheels 36, and the two movable wheels 342.

[0053] With reference to Figures 11-12 The conveying assembly 4 comprises a conveying device 41 arranged below the fixed horizontal rod 222, the output end of the conveying device 41 is fixedly connected with a steering device 43, and the output end of the steering device 43 is fixedly connected with a bearing plate 42.

[0054] By means of the conveying assembly 4, the large stone block is placed on the bearing plate 42, conveyed to the cutting area by the conveying device 41, and the direction of the stone block is adjusted according to the cutting requirement by the steering device 43, so that the stone block can be parked on the bearing plate 42 in a suitable posture, and then a suitable cutting mode can be selected according to the specifications and shape of the stone block.

[0055] In use, the large stone is placed on the bearing plate 42, conveyed to the cutting area by the conveying device 41, and the direction of the stone is adjusted by the turning device 43 according to the cutting requirements, so that the stone can be parked on the bearing plate 42 in a suitable posture, and a suitable cutting method is selected according to the specifications and shape of the stone; when the stone to be cut is a regular stone such as a cube or a cuboid, a saw blade is used for cutting; when the height of the stone is less than or equal to the cutting height of the diamond saw blade 243, the stone can be directly cut; when the height of the stone is greater than the cutting height of the diamond saw blade 243, the limiting rod 235 at the bottom of the protective cover 231 contacts the surface of the stone to prevent the diamond saw blade 243 from being damaged by excessive downward pressure, at which time the diamond saw blade 243 cannot be cut downward, but can be cut horizontally, and then converted to a rope saw cutting; during rope saw cutting, since the diamond rope saw 33 is designed in a ring shape, when the upper arc groove 233 in the tensioning frame 232 drives the upper diamond rope saw 33 to move upward, the change in tension of the ring-shaped rope saw will cause the movable wheel 342 to be pulled downward by the lower diamond rope saw 33, so that the lower diamond rope saw 33 is embedded in the cutting groove reserved by the preliminary saw blade cutting and provides tension, and then the stepping motor 31 is operated for cutting; when the stone to be cut is an irregular stone, grooving is performed using the diamond saw blade 243 first, and then cutting is performed using the diamond rope saw 33, which effectively avoids the cutting difficulties caused by the irregular shape of the stone, and at the same time, grooving can reduce the cutting resistance of the rope saw to some extent, make up for the insufficient power and cutting capacity of the rope saw, speed up the cutting, reduce cutting pauses and adjustments, and significantly improve the overall cutting efficiency.

[0056] The working principle of the present application is as follows:

[0057] In operation, the large stone is placed on the bearing plate 42, conveyed to the cutting area by the conveying device 41, and the direction of the stone is adjusted by the turning device 43 according to the cutting requirements, so that the stone can be parked on the bearing plate 42 in a suitable posture, and a suitable cutting method is selected according to the specifications and shape of the stone.

[0058] When the stone to be cut is a regular stone such as a cube or a cuboid, a saw blade is used for cutting, and the output winch 211 and the synchronous winch 215 mounted on the top of the gantry 1 are synchronously rotated through the connecting shaft 214; the output ends of the output winch 211 and the synchronous winch 215 pay out or take up the steel wire rope 213, driving the lifting cars 221 at both ends of the fixed cross bar 222 to slide in the lifting grooves 212, thereby adjusting the height of the fixed cross bar 222; then, the transverse driving device 224 drives the transverse moving frame 223 to slide on the fixed cross bar 222, moving the diamond saw blade 243 to a suitable cutting position.

[0059] The rotating assembly 24 is started, the driving motor 241 drives the rotating shaft 244 to rotate at high speed through the speed-increasing transmission belt 242, and then the diamond saw blade 243 fixed to the outer wall of the rotating shaft 244 rotates to cut the stone; when the height of the stone is less than or equal to the cutting height of the diamond saw blade 243, the stone can be directly cut; when the height of the stone is greater than the cutting height of the diamond saw blade 243, the limiting rod 235 at the bottom of the protective cover 231 contacts the surface of the stone to prevent the diamond saw blade 243 from being damaged by excessive downward pressure, and the diamond saw blade 243 cannot cut downward but can cut horizontally, and then the rope saw cutting is performed.

[0060] When the rope saw cutting is performed, the fixed horizontal rod 222 is first moved upward to reset, and then the stone is transported to the rope saw cutting position by the conveying device 41, and the fixed horizontal rod 222 continues to move upward. Since the diamond rope saw 33 is designed in a ring shape, when the upper arc groove 233 in the tensioning frame 232 drives the upper diamond rope saw 33 to move upward, the change in tension of the ring-shaped rope saw will cause the movable wheel 342 to be pulled downward by the lower diamond rope saw 33, so that the lower diamond rope saw 33 is embedded in the cutting groove reserved by the preliminary saw blade cutting and provides tension. Then, the stepping motor 31 drives the driving wheel 32 to rotate, the driving wheel 32 drives the diamond rope saw 33 through the clamping groove, and the diamond rope saw 33 cuts in turn around the first fixed wheel 35, the two second fixed wheels 36, and the two movable wheels 342.

[0061] When the stone to be cut is an irregular stone, the diamond saw blade 243 is used to groove first, and then the diamond rope saw 33 is used to cut, which effectively avoids the cutting problem caused by the irregular shape of the stone. At the same time, the grooving can reduce the cutting resistance of the rope saw to some extent, make up for the insufficient power and cutting capacity, speed up the cutting speed, reduce the cutting pause and adjustment, and significantly improve the overall cutting efficiency.

[0062] After one cutting is completed, the handling assembly 4 transports the cut stone away, a new stone is transported in, the device repeats the above working process, and continuous and efficient stone segmentation operation is realized, so that the overall production efficiency and stone processing quality are improved.

[0063] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present application and are not limiting. Although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or replaced equivalently without departing from the spirit and scope of the technical solutions of the present application, and all should be covered in the scope of the claims of the present application.
