Description

Technical Field

[0001] The utility model relates to the field of electric saw equipment, in particular to a mine saw with a protection structure. Background Technique

[0002] Stone mining equipment is a kind of mechanized equipment that divides and transports mine stones. The current mechanized mining of stones is very common, with the characteristics of energy conservation, high efficiency, high yield rate, and little damage to the mine. During the production and transportation of stones, a saw blade assembly is used for cutting. However, the saw blades of existing devices are not provided with any protection measures and are basically open. This structure will affect the service life of the saw blade and also increase the danger of the working environment. Therefore, a mine saw with a protection structure is proposed. Content of the Utility Model

[0003] The main purpose of the utility model is to provide a mine saw with a protection structure, which can effectively solve the problems in the background technique.

[0004] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0005] A mine saw with a protection structure includes an electric saw main body, a fixed protection cover, and a sliding protection frame. The surface of the electric saw main body is fixedly installed with a fixed protection cover, and the surface of the electric saw main body is fixedly connected with a sliding protection frame. The surface of the sliding protection frame is movably butted with the fixed protection cover. The sliding protection frame includes a fixed ring, sliding beads, a protection frame, a protection net, and a slider.

[0006] The electric saw main body includes a connecting frame, a driving motor, a cutter head, and a fixed frame. The surface of the connecting frame is fixedly installed with a driving motor, the output end of the driving motor is fixedly installed with a cutter head, and one end surface of the connecting frame is fixedly connected with a fixed frame.

[0007] The fixed protection cover includes a semi-open protection cover, a through hole, a sliding groove, a sliding rod, a return spring, and a butting edge strip. The surface of the semi-open protection cover is fixedly provided with a through hole, the surface of the semi-open protection cover is fixedly provided with a sliding groove, the surface of the sliding groove is fixedly connected with a sliding rod, the surface of the sliding rod is fixedly sleeved with a return spring, and the arc surface of the semi-open protection cover is fixedly provided with a butting edge strip.

[0008] The surface of the fixed ring is movably connected with sliding beads, the surface of the sliding beads is movably sleeved with a protection frame, the surface of the protection frame is fixedly provided with a protection net, and the surface of the protection frame is fixedly provided with a slider.

[0009] The semi-open protection cover is connected to the other semi-open protection cover through a butting edge strip to form a fixed protection cover. The through hole of the fixed protection cover is fixedly connected with the connecting frame of the electric saw main body.

[0010] The fixed ring is fixedly sleeved on the surface of the drive motor. The slider is movably butted with the chute. The slider is movably sleeved on the sliding rod. One side surface of the slider is attached to one end surface of the return spring.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] In the utility model, a mining saw with a protection structure protects the surface of the cutter head through the fixed protective cover, improving the safety of the device. At the same time, the chute and the sliding rod are arranged to allow the sliding protective frame to slide and open and close. By setting the sliding protective frame, the protection area of the cutter head is increased, and the large-area cutter head is wrapped in it, but it does not affect the cutting of the cutter head. When the electric saw main body makes the cutter head cut downward, the generated reaction force makes the sliding protective frame expand and open to both sides, exposing the rotating cutter head. When the cutter head stops operating and is lifted, without the push of force, the sliding protective frame will also close towards the middle through the return spring to wrap the cutter head.

[0018] In order to make the technical means, creative features, achieved purposes and functions of the utility model easy to understand, the utility model will be further described below in conjunction with specific embodiments.

[0019] Such as Figures 1-4As shown, a mining saw with a protective structure includes a power saw body 1, a fixed protective cover 2, and a sliding protective frame 3. The fixed protective cover 2 is fixedly mounted on the surface of the power saw body 1, the sliding protective frame 3 is fixedly connected to the surface of the power saw body 1, and the surface of the sliding protective frame 3 is movably connected to the fixed protective cover 2. The sliding protective frame 3 includes a fixed ring 301, a sliding bead 302, a protective frame 303, a protective net 304, and a slider 305.

[0020] The electric saw body 1 includes a connecting frame 101, a drive motor 102, a blade disc 103 and a fixed frame 104. The drive motor 102 is fixedly installed on the surface of the connecting frame 101, and the blade disc 103 is fixedly installed on the output end of the drive motor 102. The surface of one end of the connecting frame 101 is fixedly connected to the fixed frame 104; the fixed protective cover 2 includes a semi-open protective cover 201, a penetration hole 202, a slide groove 203, a sliding rod 204, a return spring 205 and a docking edge strip 206. The surface of the semi-open protective cover 201 is fixedly provided with a penetration hole 202, the surface of the semi-open protective cover 201 is fixedly provided with a slide groove 203, the surface of the slide groove 203 is fixedly connected to the sliding rod 204, the surface of the sliding rod 204 is fixedly provided with a return spring 205, and the semi-open protective cover 201 The arc surface is fixedly provided with a docking edge strip 206; the surface of the fixed ring 301 is movably connected with a sliding bead 302, the surface of the sliding bead 302 is movably sleeved with a protective frame 303, the surface of the protective frame 303 is fixedly provided with a protective net 304, and the surface of the protective frame 303 is fixedly provided with a slider 305; the semi-open guard 201 is connected to the other semi-open guard 201 through the docking edge strip 206 to form a fixed guard 2, and the through hole 202 of the fixed guard 2 is fixedly connected to the connecting frame 101 of the electric saw body 1; the fixed ring 301 is fixedly sleeved on the surface of the drive motor 102, the slider 305 is movably docked with the slide groove 203, the slider 305 is movably sleeved on the sliding rod 204, and one side surface of the slider 305 is in contact with one end surface of the reset spring 205.
