Description

Technical Field

[0001] The present invention relates to the technical field of cutting machinery, and in particular to a rock cutting device. Background Art

[0002] During the rock mining process, a rock cutting device is required to turn the rock into a square rock raw material, which is convenient for subsequent deep processing to form building materials. When using a rock cutting device to cut the rock, a track is generally used to connect the saw disc to achieve automatic and horizontal rapid cutting.

[0003] Therefore, when cutting some rocks with smaller structures, the connection structure and control structure between the track and the saw disc are relatively complicated. After the cutting is completed, the track, saw disc, connection structure and control structure need to be disassembled and transferred, and then installed, which is time-consuming and labor-intensive. In response to the above situation, a handheld rock cutting device can be used to cut and process the rock. When a conventional handheld rock cutting device is used to cut the rock, the surface of the rock is prone to unevenness. It is difficult to move the rock cutting device smoothly by hand, which makes the saw disc prone to shaking and the saw disc prone to tilting and tangent to the rock. In severe cases, the service life of the saw disc will be affected. Summary of the Invention

[0004] In response to the deficiencies in the prior art, the present invention provides a rock cutting device to solve the problem that when a handheld rock cutting device uses a saw disc to cut rock, the human hand is easily unstable in holding the device, the saw disc is easily tilted and tangent to the rock, affecting the stable cutting of the saw disc.

[0005] In order to achieve the above-mentioned purpose, the basic scheme of the present invention is as follows: a rock cutting device, including a mounting plate, a mounting frame, a saw disk and a motor for driving the saw disk to rotate, and also including several buffer lifting units, the buffer lifting unit including a spring telescopic rod and a roller, the spring telescopic rod is vertically arranged, the upper end of the spring telescopic rod is fixedly connected to the lower surface of the mounting frame, and the lower end of the spring telescopic rod is rotatably connected to the roller; the motor and the saw disk are installed on the mounting frame.

[0006] The technical principle of the present invention is: when using a rock cutting device for cutting, the mounting plate and the mounting frame can stably support the saw disk and the motor; at the same time, through the setting of the spring telescopic rod and the roller in the buffer lifting unit, the entire rock cutting device can be pushed to move along the rock surface, making the movement of the rock cutting device more labor-saving and the rock cutting more efficient and stable. When encountering an uneven rock surface, the spring telescopic rod can float naturally, so that the vertical displacement of the mounting plate and the mounting frame is smaller, the displacement changes slower, and the position of the saw disk changes slower, making the rock cutting more stable and protecting the saw disk.

[0007] Furthermore, it also includes a connecting arm, one end of which is rotationally locked to the mounting frame, and the other end of the connecting arm is rotationally connected to the axis of the saw disk. A cutting hole is vertically provided on the mounting plate for the lower side of the saw disk to pass through, and the lower side of the saw disk can be opposite to the roller.

[0008] Through the rotation setting between the connecting arm and the mounting frame, the relative position of the saw disc and the mounting frame can also change when the connecting arm rotates relative to the mounting frame. By controlling the position of the connecting arm, the position of the saw disc can be adjusted to be able to cut against the rock at the cutting hole. The cutting hole can limit the saw disc and reduce the risk of contact between human hands and the saw disc.

[0009] Furthermore, it also includes several cleaning strips and several cleaning brushes vertically installed on the cleaning strips. The cleaning strips are horizontally fixed on the lower surface of the mounting plate. The cleaning brushes are installed on the side of the cleaning strip away from the mounting plate. The cleaning strip is located between the cutting hole and the roller.

[0010] By setting up the cleaning strip and the cleaning brush, the dust and debris generated by the saw disc during cutting can be cleaned by the cleaning strip and the cleaning brush. By limiting the position of the cleaning strip, the dust and debris after cleaning can be difficult to contact the roller, so that the roller can maintain a stable rolling state.

[0011] Further, the horizontal axis of the cleaning strip intersects the horizontal axis of the cutting hole.

[0012] Through the above arrangement, the cleaning strip is inclined relative to the cutting hole, thereby directing dust and debris generated during the cleaning process out of the range of the mounting plate, thereby reducing the amount of dust and debris accumulated at the cleaning brush.

[0013] Furthermore, a protective cover covering a part of the saw disc is rotatably mounted on the connecting arm, and the protective cover is located on the upper side of the mounting plate and opposite to the mounting frame.

[0014] Through the above setting, when the saw disc is cutting the rock, the protective cover can protect the saw disc and the human hands, and the protective cover can also block dust and debris; when adjusting the position of the connecting arm, the protective cover can also be used to press or lift the end of the connecting arm close to the saw disc, making the adjustment of the saw disc position more convenient.

[0015] Furthermore, an annular frame is horizontally fixedly installed at the upper end of the mounting frame. The annular frame can be opposite to the upper side of the saw disk, and the saw disk is located within the inner ring range of the annular frame.

[0016] When pushing the entire rock cutting device to move, the entire rock cutting device can be pushed to move stably through the annular frame; at the same time, the saw disc is located within the annular frame, which can also block human hands and prevent them from accidentally touching the saw disc.

[0017] Furthermore, the spring telescopic rod includes a pneumatic telescopic rod and a spring coaxially installed outside the pneumatic telescopic rod. A mounting groove is concavely provided on the bottom of the mounting plate. The pneumatic telescopic rod is coaxially arranged in the mounting groove. The upper end of the pneumatic telescopic rod is fixedly connected to the top surface of the mounting groove of the mounting plate. The lower end of the pneumatic telescopic rod is rotatably connected to the roller. The upper end of the spring is against the top surface of the mounting groove, and the lower end of the spring is against the outer wall of the roller.

[0018] Through the above settings, the pneumatic telescopic rod and the spring can synchronously support the mounting plate, achieving a good floating effect while making the cutting of the saw disc more stable. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] The technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0024] This embodiment is basically as Figure 1 、 Figure 2 and Figure 3 As shown, an embodiment of the present invention proposes a rock cutting device, including a mounting plate 10, a mounting frame 11, a saw disc 201, a motor 202 for driving the saw disc 201 to rotate, four buffer lifting units, two connecting arms 40, four cleaning strips 50 and a number of cleaning brushes 501 vertically installed on the cleaning strips 50, a rotating shaft is welded between the motor 202 and the saw disc 201; wherein the buffer lifting unit includes a roller 60, a pneumatic telescopic rod 30 and a spring (not shown) coaxially installed outside the pneumatic telescopic rod 30, a mounting groove 101 is concavely provided on the bottom of the mounting plate 10, the pneumatic telescopic rod 30 is coaxially arranged in the mounting groove 101, the upper end of the pneumatic telescopic rod 30 is welded to the top surface of the mounting groove 101 of the mounting plate 10, the lower end of the pneumatic telescopic rod 30 is rotatably connected to the roller 60, the upper end of the spring is against the top surface of the mounting groove 101, and the lower end of the spring is against the outer wall of the roller 60.

[0025] like Figure 1 As shown, the right ends of the two connecting arms 40 are rotatably connected to the mounting frame 11, and a disc spring is installed between the connecting arm 40 and the mounting frame 11 to lock the rotation of the connecting arm 40 and the mounting frame 11; a connecting hole is provided at the left end of the two connecting arms 40, and the connecting hole of the connecting arm 40 is rotatably connected to the rotating shaft at the axis of the saw disk 201, and a cutting hole 102 is vertically provided on the mounting plate 10 for the lower side of the saw disk 201 to pass through. After the lower side of the saw disk 201 passes through the cutting hole 102, it can be opposite to the roller 60; at the same time, a protective cover 203 covering a part of the saw disk 201 is rotationally locked and installed on the connecting arm 40, and the protective cover 203 is located on the upper side of the mounting plate 10 and opposite to the mounting frame 11; the protective cover 203 is in the shape of a semicircular box, and a mounting hole is provided at the center of the protective cover 203, and the mounting hole of the protective cover 203 is coaxially arranged with the connecting hole, and a handle 204 is integrally formed on the outer wall of the protective cover 203.

[0026] like Figure 2 As shown, the cleaning bar 50 is horizontally welded on the lower surface of the mounting plate 10, and the cleaning brush 501 is installed on the lower surface of the cleaning bar 50. The cleaning bar 50 is located between the cutting hole 102 and the roller 60, and the horizontal axis of the cleaning bar 50 intersects with the horizontal axis of the cutting hole 102.

[0027] In addition, if Figure 1 As shown, a ring frame 103 is horizontally welded at the upper end of the mounting frame 11 . The ring frame 103 can be opposite to the upper side of the saw disk 201 , and the saw disk 201 is located within the inner ring range of the ring frame 103 .

[0028] When using a rock cutting device in this embodiment, the entire rock cutting device is first placed on the rock surface. After determining the cutting position, the handle 204 is held and the protective cover 203 is pressed to make the left end of the connecting arm 40 rotate around the hinge between the right end and the mounting frame 11, and then the saw disk 201 passes through the cutting hole 102 and abuts against the rock. Then the motor 202 is started, and the motor 202 drives the rotating shaft and the saw disk 201 to rotate. The rotating saw disk 201 cuts the rock. During the cutting process, continue to press the handle 204 downward to make the saw disk 201 cut deeply into the rock.

[0029] During the cutting process, a person holds the annular frame 103 by hand and pushes the entire rock cutting device to move forward. During the movement, the saw disc 201 continues to cut the rock, and the dust and debris generated during the cutting process are cleaned by the cleaning brush 501. The cleaning brush 501 and the cleaning strip 50 can tilt and guide the dust and debris so that the dust and debris are moved out of the range of the mounting frame 11, avoiding the dust and debris from being embedded in the roller 60, so that the roller 60 remains clean and rolling.

[0030] When the rock cutting device is pushed and moved, when the roller 60 rolls onto the uneven rock surface, the pneumatic telescopic rod 30 and the spring can naturally expand and contract, making the ups and downs of the saw disc 201 on the mounting plate 10 more stable, making it easier to control the position of the saw disc 201, and the contact between the saw disc 201 and the rock more stable, which can effectively protect the saw disc 201. During the above process, it is only necessary to push the entire rock cutting device and place it along the rock surface for cutting. The setting of the roller 60 saves effort in pushing the rock cutting device, and the rock cutting device is easy to move, making it easy to adjust its cutting position.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not limiting. Although the present invention 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 invention may be modified or replaced by equivalents without departing from the purpose and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
