Description

Technical Field

[0001] The invention relates to the technical field of masonry sawing, and in particular to an ecological masonry manufacturing sawing device and a sawing method. Background Art

[0002] Eco-brick is an environmentally friendly building material. It is made of waste materials, cement, sand and other materials. The cleaned waste materials are mixed with cement and sand in a certain proportion, and an appropriate amount of water is added to stir evenly; the mixed materials are put into the eco-brick mold, and the materials are compacted and formed by an extruder. The eco-bricks after extrusion need to be maintained to gradually harden and solidify the brick body. The production of small eco-bricks usually requires repeated compaction and forming, resulting in cumbersome processes. Therefore, the compacted and formed products are large eco-bricks, which are then cut into multiple small eco-bricks. However, this production method usually has the following problems:

[0003] First, conventional cutting uses a cutting knife for cutting, so it takes multiple cuts to cut a whole piece of eco-brick into multiple small pieces of eco-bricks, which will undoubtedly reduce the cutting efficiency. At the same time, the corresponding size needs to be adjusted, but the existing adjustment device is usually cumbersome, and if it encounters a hard part, it will cause the problem of difficult cutting;

[0004] Secondly, after cutting, the edges of the small pieces of ecological bricks are sharp. If the edges of the corresponding small pieces of ecological bricks are not polished and chamfered, the palms of the operators who lay the bricks will be cut.

[0017] A sawing method of an ecological masonry manufacturing sawing device, the specific operation steps are as follows:

[0018] S1: First, the driving plate is driven by an external hydraulic rod to slide with multiple telescopic plates on the support frame. Due to the existence of the inclined edge, multiple transverse plates are used to adjust the distance between two adjacent transverse plates under the action of the external retracting device. Then the bricks to be cut are placed on the multiple transverse plates, which will be used to adjust the thickness of the bricks to be cut into multiple small pieces. Then the saw rope is pulled and pulled to make the second fixed pulley, the first fixed pulley and the third fixed pulley distributed in a triangle. The saw rope between the second fixed pulley and the first fixed pulley is placed on the edge of the brick to be cut, and then the external driving motor is turned on to drive the driving rotating plate to rotate;

[0019] S2: During the rotation of the driving plate, the third fixed pulley with the protruding block is continuously pushed to rotate back and forth under the action of the reset spring, so that the saw rope is pulled back and forth on the surface of the masonry to be cut. Under the joint action of the first compression spring and the tension spring, the saw rope at one end of the circular plate is pulled down, and the saw rope on the first fixed pulley moves toward the vertical plate, thereby assisting the saw rope to cut through the masonry to be cut and complete the cutting;

[0020] S3: During the cutting process, if the hard area inside the masonry to be cut is not encountered, as the saw rope is continuously pulled, the saw rope brings the second pressing block to continuously rise and fall, but the overall trend is a downward state, that is, each descent of the second pressing block will be lower than the previous height, that is, each descent of the second pressing block is achieved by the bottom rod touching the first pressing block below and continuously descending, and as the first pressing block continues to descend, the meshing pressing tooth plate and the rotating gear will drive the rotating rod to rotate intermittently, and the spiral groove rotates in the direction of the fixed disk, and the rolling ball moves toward the annular groove under the action of the second return spring, so when the rotating rod rotates, it can push the rolling ball in the spiral groove to move toward the fixed disk, when the rotating rod stops intermittently, the rolling ball brings the annular plate to move toward the annular groove, and during the movement, the rotating rod continues to rotate, and will push the rolling ball toward the fixed disk again, that is, when the rotating rod rotates intermittently, the rolling ball will not reach the end of the spiral groove facing the annular groove;

[0021] During the cutting process, if the saw rope hits the hard area inside the masonry to be cut, the saw rope will only play a reciprocating sawing role, and cannot drive the saw rope to move inside the masonry to be cut. Therefore, the first pressing block will not continuously touch and descend, so the rotating rod will not rotate intermittently.

[0022] S4: When encountering a hard area inside the masonry to be cut during the cutting process, the top plate and the second piston at the bottom of the piston rod will be driven, and then the oil will be squeezed out of the pressing tube and flow into the connecting sleeve, so that the push rod will be retracted into the connecting sleeve, that is, the telescopic rod will move toward the protruding block, which will push and increase the swing amplitude of the third fixed pulley, that is, ultimately achieve the improvement of the degree of reciprocating pulling of the saw rope, and thus better saw the hard area inside the masonry to be cut that the saw rope touches;

[0023] S5: During the cutting process, the reciprocating pulling of the saw rope will drive the first fixed pulley and the second fixed pulley to rotate reciprocatingly, and then drive the contact disk to rotate through the cooperation of the side block and the protrusion. Since the second compression spring is in a compressed state, it will ensure that the friction ball is tightly attached to the edge of the gap in the masonry to be cut. At the same time, the rotation of the contact disk will drive the friction ball to rotate through the twisting of the second compression spring, thereby completing the function of grinding the edge of the cut gap.

[0024] The beneficial effects of the present invention are:

[0025] 1. The saw rope of the present invention is pulled back and forth on the surface of the masonry to be cut. Under the joint action of the first compression spring and the tension spring, the saw rope at one end of the circular plate is pulled down, and the saw rope on the first fixed pulley moves toward the vertical plate, thereby assisting the saw rope to cut through the masonry to be cut and complete the cutting. The telescopic rod moves toward the protruding block, which will promote the increase of the swing amplitude of the third fixed pulley, that is, ultimately achieving an increase in the degree of reciprocating pulling of the saw rope, thereby better sawing the hard area inside the masonry to be cut that the saw rope touches.

[0026] 2. In the cutting process of the present invention, the reciprocating pulling of the saw rope will drive the first fixed pulley and the second fixed pulley to rotate reciprocatingly, and then drive the contact disk to rotate through the cooperation of the side block and the protrusion. Since the second compression spring is in a compressed state, it will ensure that the friction ball is tightly attached to the edge of the gap of the masonry to be cut. At the same time, the rotation of the contact disk will drive the friction ball to rotate through the twisting of the second compression spring, thereby completing the function of grinding the edge of the cut gap.

[0048] The symmetrical side walls of the support frame 2 are respectively provided with a first side hole 3 and a third side hole 8, a plurality of telescopic plates 4 are inserted into the first side hole 3, and the plurality of telescopic plates 4 are connected with the same driving plate 6, wherein the telescopic plate 4 is located between two adjacent transverse plates 17, and an inclined edge 5 is provided at one end of the telescopic plate 4. The driving plate 6 is driven by an external hydraulic rod to telescope and slide with the plurality of telescopic plates 4 on the support frame 2. Due to the existence of the inclined edge 5, as the plurality of transverse plates 17 are acted upon by the external folding device, the spacing between two adjacent transverse plates 17 can be adjusted.

[0049] The transverse plate 17 slides on the third side hole 8, and the vertical plate 11 slides on the supporting frame 2 through the second side hole 7, and the masonry 1 to be cut is placed on multiple transverse plates 17, which will be used to adjust the thickness of the masonry to be cut into multiple small pieces, that is, the distance between two adjacent transverse plates 17 is the thickness of the masonry to be cut.

[0050] A vertical plate 11 vertically penetrates the transverse plate 17, a top frame 9 is provided on the vertical plate 11, a circular plate 22 and a third fixed pulley 24 are respectively provided at both ends of the vertical plate 11, a second fixed pulley 23 is provided on the top frame 9, a first fixed pulley 18 slides on the transverse plate 17, a same saw rope 10 for sawing the bricks and stones 1 to be cut is provided between the circular plate 22 and the third fixed pulley 24, one end of the saw rope 10 is fixed to the circular plate 22, and the other end of the saw rope 10 is wound around the third fixed pulley 24, the first fixed pulley 18 and the second fixed pulley 23 are used to change the pulling direction of the saw rope 10, and the saw rope 10 is connected to the bricks and stones 1 to be cut.

[0051] The first fixed pulley 18 slides on the side wall of the transverse plate 17 through the sliding block 19 and the tension spring 20, so that the saw rope 10 is pulled and pulled, so that the second fixed pulley 23, the first fixed pulley 18 and the third fixed pulley 24 are distributed in a triangle, and the saw rope 10 between the second fixed pulley 23 and the first fixed pulley 18 is placed on the edge of the brick 1 to be cut, so as to facilitate the subsequent cutting of the brick 1 to be cut by the saw rope 10, and then the external drive motor is turned on to drive the driving rotating plate 28 to rotate.

[0052] The saw rope 10 passes through the first fixed pulley 18 and the second fixed pulley 23. During the cutting process, the reciprocating pulling of the saw rope 10 will drive the first fixed pulley 18 and the second fixed pulley 23 to rotate reciprocatingly. Two friction balls 63 are sleeved on the saw rope 10, and the first fixed pulley 18 and the second fixed pulley 23 are both provided with side blocks 65. Two contact plates 66 are also sleeved on the saw rope 10, and the contact plates 66 are provided with multiple protrusions 67 that cooperate with the side blocks 65 on the side facing the first fixed pulley 18 and the second fixed pulley 23, and the multiple protrusions 67 are arranged in a circle, and then the side blocks 65 cooperate with the protrusions 67 to drive the contact plates 66 to rotate, that is, drive the contact plates 66 to rotate reciprocatingly.

[0053] A second compression spring 64 mounted on the saw rope 10 is provided between the contact plate 66 and the friction ball 63. Since the second compression spring 64 is in a compressed state, it ensures that the friction ball 63 is tightly attached to the edge of the gap cut in the masonry 1 to be cut. At the same time, the rotation of the contact plate 66 will drive the friction ball 63 to rotate through the twisting of the second compression spring 64, thereby completing the function of grinding the edge of the cut gap.

[0054] A lifting block 16 for lifting the masonry 1 to be cut is provided on the top of the transverse plate 17, and a pressing plate 13 for pressing and positioning the masonry 1 to be cut is provided above the transverse plate 17. The pressing plate 13 is lifted and slid on the transverse plate 17 through a pulling rod 14 and a longitudinal through hole 21. A counterweight block 15 for driving the pressing plate 13 to press down is provided at the bottom of the pulling rod 14, so that the masonry 1 to be cut placed on the transverse plate 17 can be fixed to avoid the masonry falling off after cutting during the cutting process.

[0055] A telescopic rod 33 for adjusting the swing amplitude of the third fixed pulley 24 is provided on the vertical plate 11 , and drives the rotating plate 28 to rotate under the action of an external driving motor.

[0056] Reference Figure 8-Figure 10 As shown, the vertical plate 11 is provided with a first inner cavity 26 and a second inner cavity 27, and the first inner cavity 26 is provided with a first connecting bracket 31, and the first connecting bracket 31 is lifted and slid in the first inner cavity 26 through the sliding plate 30 and the side slide groove 29, and the sliding plate 30 is lifted and slid by the first return spring 35 and the limit rod 36, and a driving rotating plate 28 is rotated in the second inner cavity 27, and the driving rotating plate 28 is rotated by an external driving motor, and the driving rotating plate 28 is against the first connecting bracket 31, so each time the driving rotating plate 28 rotates, it will press the first connecting bracket 31 to drive the telescopic rod 33 to descend, and at the same time compress the first return spring 35.

[0057] A through sleeve 32 is fixed at the bottom of the first connecting bracket 31, and the through sleeve 32 is arranged to be inclined downward, a telescopic rod 33 is coaxially inserted in the through sleeve 32, a protruding block 34 is provided on the third fixed pulley 24, the third fixed pulley 24 rotates on the vertical plate 11 through the roller bracket 25, and the third fixed pulley 24 is reset and rotated on the roller bracket 25 through the reset spring, one end of the telescopic rod 33 is against the protruding block 34, and the other end of the telescopic rod 33 is connected to the through sleeve 32 with a coaxially arranged push rod 37 and a connecting sleeve 38.

[0058] During the rotation process of the driving rotating plate 28, the third fixed pulley 24 with the protruding block 34 is continuously pushed to rotate back and forth under the action of the reset spring, so that the pulling saw rope 10 will be pulled back and forth on the surface of the brick 1 to be cut. Under the joint action of the first compression spring 46 and the tension spring 20, the pulling saw rope 10 at one end of the circular plate 22 is pulled down, and the pulling saw rope 10 on the first fixed pulley 18 moves toward the vertical plate 11, thereby assisting the pulling saw rope 10 to cut through the brick 1 to be cut and complete the cutting.

[0059] Reference Figure 12-16 The state is a schematic diagram of a state in which the telescopic rod 33 is lifted and lowered to drive the third fixed pulley 24 to swing.

[0060] Fig.12State: At this time, the telescopic rod 33 is pressed to the lowest point, and the reset spring is in an uncharged state. The first reset spring 35 is in a compressed state. Under the elastic force of the first reset spring 35, the third fixed pulley 24 with the protruding block 34 is lifted and pushed to rotate clockwise;

[0061] Fig.13 State: At this time, the telescopic rod 33 is in the lifting state, and the reset spring is in the continuous power storage state. The first reset spring 35 is still in the compressed state, but at this time, in order to release energy, the third fixed pulley 24 with the protruding block 34 rotates clockwise;

[0062] Fig.14 State: At this time, the telescopic rod 33 is in the lifting state, the reset spring is in the continuous power storage state, the first reset spring 35 is still in the compressed state, the protruding block 34 is in the critical state of being separated from the telescopic rod 33, and the third fixed pulley 24 is in the maximum range of clockwise rotation;

[0063] Fig.15 and Fig.16 State: At this time, the telescopic rod 33 is in the state of being pressed by the driven rotating plate 28. At this time, the first reset spring 35 is compressed, and the third fixed pulley 24 is reset by the reset spring after the power is stored. When the telescopic rod 33 is pressed down, the side close to the protruding block 34 is an arc surface, which is convenient for the protruding block 34 to drive the third fixed pulley 24 to rotate counterclockwise, so that the protruding block 34 returns to the other side of the telescopic rod 33 and returns to the Fig.12 state.

[0064] It should be noted that the reciprocating swing of the third fixed pulley 24 at this time is the effect of pulling the saw rope 10 to reciprocate, and as the telescopic rod 33 is extended, the telescopic rod 33 will push the third fixed pulley 24 to rotate clockwise, such as Fig.14 In this state, the third fixed pulley 24 rotates clockwise with increasing amplitude, so that the third fixed pulley 24 can pull the saw rope 10 with increasing amplitude to better saw the masonry 1 to be cut.

[0065] A sliding groove 12 is opened on the vertical plate 11, and a first pressing block 42 and a second pressing block 43 slide on the sliding groove 12. The first pressing block 42 slides in the sliding groove 12 through a friction layer 41 arranged on the side wall of the sliding groove 12. Therefore, the first pressing block 42 is not affected by external force and stays in the sliding groove 12 by friction.

[0066] A third inner cavity 47 is also provided in the vertical plate 11, a lower pressing tooth plate 48 extending into the third inner cavity 47 is provided at the bottom of the first lower pressing block 42, the second lower pressing block 43 is pressed down by a first compression spring 46, the circular plate 22 is connected to the second lower pressing block 43 by a buffer spring 45, and a bottom rod 44 is provided at the bottom of the second lower pressing block 43. During the cutting process, if the hard area inside the masonry 1 to be cut is not touched, as the saw rope 10 is continuously pulled, the saw rope 10 continuously rises and falls with the second lower pressing block 43, but the overall trend is a descending state, that is, each descent of the second lower pressing block 43 will be lower than the previous height, that is, each descent of the second lower pressing block 43 is achieved by the bottom rod 44 touching the first lower pressing block 42 below and continuously descending.

[0067] A rotating rod 49 is provided in the third inner cavity 47, and an annular groove 50 is provided on the rotating rod 49. A rotating gear 51 is coaxially provided in the annular groove 50, and the lower pressure tooth plate 48 meshes with the rotating gear 51. A fixed disk 59 fixed in the third inner cavity 47 is provided at the end of the rotating rod 49. A spiral groove 52 is provided on the outer wall of the rotating rod 49, and a rolling ball 53 is provided in the spiral groove 52. Annular plates 54 sliding on the outer wall of the rotating rod 49 are provided on both sides of the rolling ball 53. The two annular plates 54 are connected by a second connecting bracket 55. The fixed disk 59 coaxially penetrates the pressing tube 61. A second piston 60 slides in the pressing tube 61. The second connecting bracket 55 is connected to the piston rod 58 through the third connecting bracket 56 and the top plate 57. A second return spring 62 is sleeved on the outer wall of the rotating rod 49, and the two ends of the second return spring 62 are respectively connected to the annular plate 54 and the fixed disk 59.

[0068] As the first pressing block 42 is continuously lowered, the meshing pressing tooth plate 48 and the rotating gear 51 drive the rotating rod 49 to rotate intermittently, and the spiral groove 52 rotates in the direction toward the fixed plate 59, and the rolling ball 53 moves toward the annular groove 50 under the action of the second return spring 62. Therefore, when the rotating rod 49 rotates, it can push the rolling ball 53 in the spiral groove 52 to move toward the fixed plate 59. When the rotating rod 49 stops intermittently, the rolling ball 53 moves with the annular plate 54 toward the annular groove 50. During the movement, the rotating rod 49 continues to rotate and pushes the rolling ball 53 toward the fixed plate 59 again. That is, when the rotating rod 49 rotates intermittently, the rolling ball 53 does not reach the end of the spiral groove 52 toward the annular groove 50.

[0069] During the cutting process, if the saw rope 10 hits the hard area inside the brick 1 to be cut, the saw rope 10 will only play the role of continuous reciprocating sawing, and cannot drive the saw rope 10 to move inside the brick 1 to be cut. Therefore, the first pressing block 42 will not continuously touch and descend, and the rotating rod 49 will not rotate intermittently.

[0070] The push rod 37 is slidably connected to the connecting sleeve 38 through the first piston 39, and the connecting sleeve 38 is connected to the pressing tube 61 through the rubber tube 40. When encountering a hard area inside the brick 1 to be cut during the cutting process, it will drive the top plate 57 and the second piston 60 at the bottom of the piston rod 58, and then squeeze the oil from the pressing tube 61 and flow into the connecting sleeve 38, so that the push rod 37 will be retracted into the connecting sleeve 38, and the telescopic rod 33 will be moved toward the protruding block 34, which will push the third fixed pulley 24 to increase the swing amplitude, and finally achieve the degree of reciprocating pulling of the saw rope 10, so as to better saw the hard area inside the brick 1 to be cut that the saw rope 10 touches.

[0071] The working principle of the present invention is as follows:

[0072] S1: First, the driving plate 6 is driven by an external hydraulic rod to slide with multiple telescopic plates 4 on the support frame 2. Due to the existence of the inclined edge 5, multiple transverse plates 17 are used to adjust the distance between two adjacent transverse plates 17 under the action of the external folding device. Then, the masonry 1 to be cut is placed on the multiple transverse plates 17, which will be used to adjust the thickness of the masonry to be cut into multiple small pieces. Then, the saw rope 10 is pulled and pulled, so that the second fixed pulley 23, the first fixed pulley 18 and the third fixed pulley 24 are distributed in a triangle, and the saw rope 10 between the second fixed pulley 23 and the first fixed pulley 18 is placed on the edge of the masonry 1 to be cut, and then the external driving motor is turned on to drive the driving rotating plate 28 to rotate;

[0073] S2: During the rotation of the driving plate 28, the third fixed pulley 24 with the protruding block 34 is continuously pushed to rotate back and forth under the action of the reset spring, so that the saw rope 10 is pulled back and forth on the surface of the masonry 1 to be cut. Under the joint action of the first compression spring 46 and the tension spring 20, the saw rope 10 at one end of the circular plate 22 is pulled down, and the saw rope 10 on the first fixed pulley 18 moves toward the vertical plate 11, thereby assisting the saw rope 10 to cut through the masonry 1 to be cut and complete the cutting;

[0074] S3: During the cutting process, if the hard area inside the masonry 1 to be cut is not encountered, as the saw rope 10 is continuously pulled, the saw rope 10 brings the second pressing block 43 up and down continuously, but the overall trend is a downward state, that is, each descent of the second pressing block 43 will be lower than the previous height, that is, each descent of the second pressing block 43 is achieved by the bottom rod 44 touching the first pressing block 42 below and continuously descending, and as the first pressing block 42 continues to descend, the meshing pressing tooth plate 48 and the rotating gear 51 drive the rotating rod 49 to rotate intermittently, and the spiral groove 52 rotates to rotate the rotating gear 51. The rotating rod 49 moves toward the fixed plate 59, and the rolling ball 53 moves toward the annular groove 50 under the action of the second return spring 62. Therefore, when the rotating rod 49 rotates, it can push the rolling ball 53 in the spiral groove 52 to move toward the fixed plate 59. When the rotating rod 49 stops intermittently, the rolling ball 53 moves toward the annular groove 50 with the annular plate 54. During the movement, the rotating rod 49 continues to rotate and pushes the rolling ball 53 toward the fixed plate 59 again. That is, when the rotating rod 49 rotates intermittently, the rolling ball 53 does not reach the end of the spiral groove 52 toward the annular groove 50.

[0075] During the cutting process, if the saw rope 10 hits the hard area inside the masonry 1 to be cut, the saw rope 10 will only play a reciprocating sawing role, and cannot drive the saw rope 10 to move inside the masonry 1 to be cut. Therefore, the first pressing block 42 will not continuously touch and descend, so the rotating rod 49 will not rotate intermittently;

[0076] S4: When encountering a hard area inside the masonry 1 to be cut during the cutting process, the top plate 57 and the second piston 60 at the bottom of the piston rod 58 will be driven, and then the oil will be squeezed out from the pressing tube 61 and flow into the connecting sleeve 38, so that the push rod 37 will be retracted into the connecting sleeve 38, that is, the telescopic rod 33 will move toward the protruding block 34, which will push and increase the swing amplitude of the third fixed pulley 24, that is, finally achieve the degree of reciprocating pulling of the saw rope 10, and then better saw the hard area inside the masonry 1 to be cut that the saw rope 10 touches;

[0077] S5: During the cutting process, the reciprocating pulling of the saw rope 10 will drive the first fixed pulley 18 and the second fixed pulley 23 to rotate reciprocatingly, and then drive the contact plate 66 to rotate through the cooperation of the side block 65 and the protrusion 67. Since the second compression spring 64 is in a compressed state, it will ensure that the friction ball 63 is tightly attached to the edge of the gap cut in the masonry 1 to be cut. At the same time, the rotation of the contact plate 66 will drive the friction ball 63 to rotate through the twisting of the second compression spring 64, thereby completing the function of grinding the edge of the cut gap.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.

10. A sawing method of an ecological brick and stone manufacturing sawing device, using the ecological brick and stone manufacturing sawing device of claim 9, characterized in that: The specific steps are as follows: S1: First, the driving plate (6) is driven by an external hydraulic rod to carry multiple telescopic plates (4) to telescope and slide on the support frame (2). Due to the existence of the inclined edge (5), the multiple transverse plates (17) are used to adjust the distance between two adjacent transverse plates (17) under the action of the external folding device. Then, the bricks (1) to be cut are placed on the multiple transverse plates (17). This will be used to adjust the thickness of the bricks to be cut into multiple small pieces. Then, the saw rope (10) is pulled and pulled to make the second fixed pulley (23), the first fixed pulley (18) and the third fixed pulley (24) distributed in a triangle. The saw rope (10) between the second fixed pulley (23) and the first fixed pulley (18) is placed on the edge of the brick (1) to be cut. Then, the external driving motor is turned on to drive the driving rotating plate (28) to rotate; S2: During the rotation process of the driving rotating plate (28), the third fixed pulley (24) with the protruding block (34) is continuously pushed to rotate back and forth under the action of the reset spring, so that the pulling saw rope (10) is pulled back and forth on the surface of the masonry (1) to be cut. Under the joint action of the first compression spring (46) and the tension spring (20), the pulling saw rope (10) at one end of the circular plate (22) is pulled down, and the pulling saw rope (10) on the first fixed pulley (18) moves toward the vertical plate (11), thereby assisting the pulling saw rope (10) to cut through the masonry (1) to be cut and complete the cutting; S3: During the cutting process, if the hard area inside the masonry (1) to be cut is not encountered, as the saw rope (10) is continuously pulled, the saw rope (10) brings the second pressing block (43) up and down continuously, but the overall trend is a downward state, that is, each descent of the second pressing block (43) will be lower than the previous height, that is, each descent of the second pressing block (43) is achieved by the bottom rod (44) touching the first pressing block (42) below and continuously descending. As the first pressing block (42) continues to descend, the meshing pressing tooth plate (48) and the rotating gear (51) drive the rotating rod (49) to rotate intermittently, and the direction of rotation of the spiral groove (52) is toward the fixed disk. (59), and the rolling ball (53) moves toward the annular groove (50) under the action of the second return spring (62), so when the rotating rod (49) rotates, it can push the rolling ball (53) in the spiral groove (52) to move toward the fixed plate (59), and when the rotating rod (49) stops intermittently, the rolling ball (53) moves toward the annular groove (50) with the annular plate (54). During the movement, the rotating rod (49) continues to rotate and pushes the rolling ball (53) toward the fixed plate (59) again, that is, when the rotating rod (49) rotates intermittently, the rolling ball (53) does not reach the end of the spiral groove (52) toward the annular groove (50); During the cutting process, if the saw rope (10) hits a hard area inside the masonry (1) to be cut, the saw rope (10) will only play a reciprocating sawing role, and will not be able to drive the saw rope (10) to move inside the masonry (1) to be cut. Therefore, the first pressing block (42) will not continuously touch and descend, and the rotating rod (49) will not rotate intermittently. S4: When encountering a hard area inside the masonry (1) to be cut during the cutting process, the top plate (57) and the second piston (60) at the bottom of the piston rod (58) will be driven, and the oil will be squeezed out from the pressing tube (61) and flow into the connecting sleeve (38), thereby retracting the push rod (37) into the connecting sleeve (38), that is, moving the telescopic rod (33) toward the protruding block (34), which will push and increase the swing amplitude of the third fixed pulley (24), and finally achieve the degree of reciprocating pulling of the saw rope (10), so as to better saw the hard area inside the masonry (1) to be cut that the saw rope (10) touches; S5: During the cutting process, the reciprocating pulling of the saw rope (10) will drive the first fixed pulley (18) and the second fixed pulley (23) to rotate reciprocatingly, and then drive the contact plate (66) to rotate through the cooperation of the side block (65) and the protrusion (67). Since the second compression spring (64) is in a compressed state, it will ensure that the friction ball (63) is in close contact with the edge of the gap cut in the masonry (1) to be cut. At the same time, the rotation of the contact plate (66) will drive the friction ball (63) to rotate through the twisting of the second compression spring (64), thereby completing the effect of grinding the edge of the cut gap.
