Description

Technical Field

[0001] The invention relates to a slotting machine, in particular to a slotting machine protective cover. Background Art

[0002] The slotting machine uses water cutting when slotting to eliminate dust, which is both environmentally friendly and healthy.

[0003] However, in actual operation, when using a slotting machine to make vertical slots, the sludge formed by the slotting will accumulate on the inner side of the existing movable arc cover, which is easy to form siltation. At this time, the rotation resistance of the slotting blade increases, and the working efficiency is low; more seriously, when the high-speed rotating slotting blade passes through the sludge, the silted sludge will stick to the blade and be brought into the fixed arc cover, which is not easy to discharge, resulting in space blockage and increasing the overall weight of the protective cover, which not only accelerates the consumption of the user's physical strength, but also increases the load of the slotting machine and even shortens the service life of the machine.

[0004] Therefore, it is urgent to provide a slotting machine protective cover to solve the above technical problems. Summary of the invention

[0005] The purpose of the present invention is to provide a slotting machine protective cover, which has a simple structure, is easy to use, can quickly discharge the sludge formed in the slotting process, improve the slotting work efficiency, save the user's physical strength, and ensure the service life of the slotting machine.

[0006] In order to achieve the above-mentioned purpose, the present invention provides a slotting machine protective cover, which includes a fixed arc cover and a movable arc cover rotatably hinged on the fixed arc cover, a spring is detachably fixed between the movable arc cover and the fixed arc cover, and the movable arc cover can be driven downward by the spring to press the cover to provide a slotting blade or to drive the movable arc cover to flip up to expose the slotting blade, a guide wheel is installed at the end of the movable arc cover, and a sewage outlet is formed on the movable arc cover.

[0007] Preferably, a long flexible board is fixed between the sewage outlet and the hinge, one end of the long flexible board extends along the tangent direction of the movable arc cover to partially or completely cover the sewage outlet, and the other end extends along the tangent direction of the movable arc cover to cover the hinge, so that when the movable arc cover is flipped up, the other end of the long flexible board bends inward and rests on the outer edge of the fixed arc cover.

[0008] Preferably, the width of the long flexible board is greater than the width of the sewage outlet.

[0009] Preferably, a short soft plate is fixed between the sewage outlet and the guide wheel, and the short soft plate extends outward along the tangent direction of the movable arc cover.

[0010] Preferably, a guide wheel hole is formed on the short soft plate, so that the guide wheel can pass through and be exposed during the slotting operation.

[0011] According to the above technical solution, the present invention forms a sewage outlet on the movable arc cover. In actual operation, when the slotting machine is used for slotting, the formed sludge will not form sticky silt in the movable arc cover, but will be quickly discharged from the sewage outlet, and the slotting blade will rotate without resistance, and the operation will be smooth. At the same time, it avoids space blockage and increases the overall weight, reduces the physical exertion of the user and the load of the slotting machine, and prolongs the service life of the machine.

[0029] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0030] In the present invention, unless otherwise stated, directional words such as "upper, lower, inside, outside" contained in a term merely represent the orientation of the term in normal usage, or are common names understood by those skilled in the art, and should not be regarded as limitations on the term.

[0031] See also Figures 1 to 9 The present invention provides a slotting machine protective cover, which includes a fixed arc cover 1 and a movable arc cover 2 rotatably hinged on the fixed arc cover 1, a spring 3 is detachably fixed between the movable arc cover 2 and the fixed arc cover 1, and the spring 3 can be used to drive the movable arc cover 2 to press down a slotting blade 4 or drive the movable arc cover 2 to flip up so that the slotting blade 4 is exposed, a guide wheel 5 is installed at the end of the movable arc cover 2, and a sewage outlet 6 is formed on the movable arc cover 2.

[0032] Through the above technical solution, a sewage outlet 6 is formed on the movable arc cover 2. In actual operation, when the slotting machine is used for slotting, the formed sludge will not form sticky silt in the movable arc cover 2, but will be quickly discharged from the sewage outlet 6, and the slotting blade 4 will rotate without resistance and work smoothly. At the same time, space blockage and increase in overall weight are avoided, the physical exertion of the user and the load of the slotting machine are reduced, and the service life of the machine is extended.

[0033] In one embodiment, a long flexible board 7 is fixed between the sewage outlet 6 and the hinge, and one end of the long flexible board 7 extends along the tangent direction of the movable arc cover 2 to partially or completely cover the sewage outlet 6, and the other end extends along the tangent direction of the movable arc cover 2 to cover the hinge, so that when the movable arc cover 2 is flipped up, the other end of the long flexible board 7 bends inward and rests on the outer edge of the fixed arc cover 1.

[0034] When in use, once the sludge generated by slotting enters the movable arc cover 2, it will immediately pass through the sewage outlet 6 and fall to one end of the long soft board 7. Since the long soft board 7 extends along the tangent direction of the movable arc cover 2, a gap is formed between the long soft board 7 and the sewage outlet 6, and the sludge is quickly discharged from the slotting machine protective cover through the gap. When slotting, the water sprayed toward the slotting blade 4 is affected by the centrifugal force and is thrown into the movable arc cover by the rotation of the slotting blade 4. At this time, the long soft board 7 can block all the splashing sewage to prevent the operator from getting wet and contaminated.

[0035] Since the long soft board 7 is soft in texture, it can undergo a certain deformation and has the ability to rebound and reset. Therefore, even if the amount of sludge passing through the sewage outlet 6 is large, once the pressure on one end of the long soft board 7 increases, this end will gradually bend outward, making the gap between it and the sewage outlet 6 larger and larger. At this time, the sewage channel is larger and more unobstructed, and a large amount of sludge can still be discharged from the protective cover quickly and smoothly.

[0036] After the sludge is discharged, the pressure originally applied to one end of the long flexible plate 7 gradually decreases. At this time, the elastic restoring force of the material of the long flexible plate 7 itself can restore it to the tangential direction without interfering with other operations of the slotting machine.

[0037] When the movable arc cover 2 is turned up, the other end of the long soft board 7 bends inward and rests on the outer edge of the fixed arc cover 1. At this time, when the slotting machine is used for slotting, the slotting blade 4 slots deeper, and the sewage is thrown to the hinge between the movable arc cover 2 and the fixed arc cover 1 during high-speed rotation, and the other bent end of the long soft board 7 can completely block the sewage, preventing it from splashing and contaminating the slotting environment and the operator's clothes, and can also ensure that the slotting machine host is not wet and leaking electricity, making it safer and more efficient to use.

[0038] In order to prevent the overflow of sludge or sewage during the sewage discharge process with the largest possible area, preferably, the width of the long soft board 7 is larger than the width of the sewage outlet 6.

[0039] Furthermore, a short soft board 8 is fixed between the sewage outlet 6 and the guide wheel 5, and the short soft board 8 extends outward along the tangent direction of the movable arc cover 2. In this way, the short soft board 8 can cooperate with the long soft board 7 to expand the area of ​​anti-splash sewage and anti-splash sludge while ensuring the sewage discharge capacity of the sewage outlet 6, thereby improving the anti-fouling capacity. At the same time, in order to ensure that the guide wheel 5 can smoothly assist in rolling during the slotting operation and save the physical effort of the slotting, preferably, a guide wheel hole 9 is formed on the short soft board 8, which is used for the guide wheel 5 to pass through and be exposed during the slotting operation.

[0040] In addition, a pair of protrusions are formed on one end of the movable arc cover 2 near the hinge, and a reserved groove for the slotting blade 4 to pass through is formed between the pair of protrusions, and a pair of waterproof plates are formed from the protrusions to the guide wheel 5, and the width of the waterproof plates gradually decreases. In this way, the pair of waterproof plates form a relatively closed waterway on the movable arc cover 2, so that the sewage formed during the slotting process can be discharged in a centralized manner, and will not splash out from other positions to pollute the working environment.

[0041] During use, the movable arc cover 2 is flipped up to expose most of the slotting blade 4. At this time, the slotting machine can be used close to the corner to cut the ground and the wall at the same time with the slotting blade 4, thereby improving the efficiency of the slotting work. When the slotting blade 4 is cutting the ground vertically downward, the guide wheel 5 on the movable arc cover 2 can be used to easily move the slotting machine to the ground by pulling to form a cutting slot. Similarly, when the slotting blade 4 is used to cut the wall horizontally or vertically, the guide wheel 5 can also be used to save the physical energy of slotting.

[0042] In order to facilitate installation and fixation, a wing plate is formed on the fixed arc cover 1 along the radial direction, and a first mounting hole for mounting a water spray pipe is formed on one side wing plate, and a second mounting hole for mounting on the slotting machine head is formed on the other side wing plate.

[0043] In addition, the bottom of the fixed arc cover 1 extends outward in the radial direction to form a guide groove, and an elliptical sewage inlet is provided on the side wall of the fixed arc cover 1 near the guide groove, so that the sewage falling into the guide groove enters from the sewage inlet, flows along the sewage groove formed by the fixed arc cover 1 and the wing plate to the drain hole and then is discharged. In this way, when the slotting blade 4 cuts vertically upward, the water sprayed from the water spray pipe during dust removal will smoothly fall into the guide groove, flow along the sewage groove formed by the fixed arc cover 1 and the wing plate, flow to the drain hole and then be discharged from the protective cover, and will not flow downward from the protective cover at will, so as to avoid affecting the operating line of sight of the slotting operator, and also effectively prevent the sewage from wetting the slotting machine body below, greatly reducing the probability of electric shock casualties caused by leakage of the body, which is safe and efficient.

However, the present invention is not limited to the specific details in the above embodiments.
