DETAILED DESCRIPTION

[0028] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0029] Reference Figure 1-7 As shown,

[0030] A grinding device with dust removal function, comprising a bracket 1, a grinding wheel machine 2 installed on the bracket 1, an outer cover 3 installed on the bracket 1, and

[0031] A water reservoir 4 is installed below the outer cover 3, is communicated with the outer cover 3, and is used to store water;

[0032] The baffle 5 is installed in the outer cover 3 to block flying chips.

[0033] The fan 6 is mounted on the outer cover 3 or the bracket 1;

[0034] The outer cover 3 is provided with an air duct 7 connected to the fan 6. The fan 6 forms a negative pressure in the outer cover 3 to attract flying debris into the water reservoir 4 and / or attract the baffle 5 and block it before falling into the water reservoir 4.

[0035] In this solution, the grinding machine 2 is installed on the bracket 1, and the outer cover 3 is installed on the bracket 1. The outer cover 3 can alleviate the splashing of debris. When the grinding machine 2 is grinding, the debris mainly splashes in one direction. Based on this phenomenon, a water reservoir 4 is arranged under the outer cover 3, which can allow the splashing debris to enter the water in the water reservoir 4, thereby reducing the problem of debris splashing. The baffle 5 extends to the position of the water reservoir 4, which can allow the debris to splash and hit the baffle 5 and fall into the water, thereby improving the dust removal effect.

[0036] In a preferred arrangement, a fan 6 is also installed on the bracket 1 or the outer cover 3 , and an air duct 7 connected to the fan 6 is provided in the outer cover 3 . The fan 6 forms a negative pressure in the outer cover 3 to attract flying debris into the water reservoir 4 .

[0037] The fan 6 on the bracket 1 or the outer cover 3 is used to blow air outward, that is, negative pressure is formed in the outer cover 3. The negative pressure can attract the debris generated by the grinding machine 2 (i.e., grinding machine 2). After the negative pressure attracts the debris, it is blocked by the baffle 5. As the baffle 5 blocks it, it falls into the stored water, thereby achieving a more efficient dust removal effect.

[0038] One end of the baffle 5 corresponding to the water reservoir 4 is preferably configured to have a serrated structure, which can increase the ventilation volume, and the serrated baffle 5 can extend into the water reservoir 4. After the fan 6 is started and negative pressure is formed in the outer cover 3, the baffle 5 extends into the water reservoir 4. At this time, the airflow generated by the negative pressure can pass through the middle of the sawtooth, and the carried debris is also partially blocked by the baffle 5 and enters the water reservoir, and some of it is blocked and filtered by the water reservoir while passing through the middle position of the sawtooth.

[0039] In order to further increase the blocking effect on debris, the number of baffles 5 is two, and they are arranged front and back to form a double-layer structure, and the serrations between the two baffles 5 are staggered.

[0040] The baffle 5 is arranged as a double-layer structure, and the serrations are staggered, which can increase the ventilation volume while having a double-layer blocking effect. The staggered serrations of the double-layer structure can compensate for the gaps between the serrations of the first layer of baffle 5, making the blocking effect better. The negative pressure and the collision of debris with the water surface can allow the baffle 5 to have a certain degree of moisture, which has better adhesion and buffering effects. When the debris hits the baffle 5, the splashing action of the debris is weakened by the buffering and adhesion of the moisture, making it easier to remove dust by storing water.

[0041] In the specific setting, the air duct 7 is located above the water reservoir 4, and the air duct 7 is connected to the water reservoir 4, and the negative pressure flows in the order of the grinding machine 2, the water reservoir 4, the air duct 7, and the fan 6.

[0042] This solution can be implemented in the following two ways:

[0043] 1. The airflow passes directly between the teeth of the baffle plate 5. At this time, the flying chips generated by the grinding machine 2 will be attracted by the airflow and move with the airflow. The airflow passes through the grinding machine 2, the gap between the teeth of the baffle plate 5, the liquid surface of the water storage, the air duct 7, and the fan 6 in sequence. In this solution, the liquid surface is low, and the airflow only passes through the gap between the teeth.

[0044] 2. The liquid level is high and can partially cover the saw teeth. At this time, because the airflow has to pass through the gaps between the saw teeth, and the gaps between the saw teeth are mostly or completely covered by water, the airflow will push the liquid surface to pass through the gaps between the saw teeth. At this time, the liquid surface disturbance is large, which can wet the baffle 5. In addition, because the airflow pushes the liquid surface to pass through the saw teeth, the liquid surface has a better surrounding effect on the airflow, which can improve the dust removal effect.

[0045] In order to further facilitate user observation and operation, the water reservoir 4 is provided with an opening 8 , and the opening 8 is located outside the outer cover 3 .

[0046] The opening 8 of the water reservoir 4 allows the user to conveniently observe the water storage condition and the debris accumulated in the water storage, and also facilitates the filling of water into the water reservoir 4 or the replacement of the water storage.

[0047] In addition, a baffle plate 9 is provided on one side of the air duct 7 away from the baffle plate 5 . The baffle plate 9 extends toward the bottom of the water reservoir 4 , and a gap or spacing space is provided between the end of the corresponding water reservoir 4 and the bottom of the water reservoir 4 .

[0048] The setting of the baffle plate 9 can make the airflow of the air duct 7 be concentrated at the baffle plate 5, and the negative pressure effect is more concentrated. The reserved interval or gap can keep the water level in the water tank balanced, and it is also convenient to clean up the debris.

[0049] Preferably, a water level line 10 is provided on one side of the baffle plate 9 corresponding to the opening 8 of the water reservoir 4. The setting of the water level line 10 will affect the dust removal effect, so setting the water level line 10 on the baffle plate 9 can facilitate the user to operate, so that the dust removal effect can be in a better state.

[0050] In a further preferred solution, a float valve 11 is provided in the water reservoir 4 , and the float valve 11 is connected to the water inlet pipe for opening and closing the water inlet pipe; the opening and closing liquid levels of the float valve 11 correspond to the water level line 10 .

[0051] The float valve 11 can automatically open and close the water inlet pipe according to the height of the liquid level. The opening and closing liquid level of the float valve 11 corresponds to the water level line 10, which can make it more convenient for users to fill water. The water inlet pipe can be directly connected to tap water, which is more convenient to operate.

[0052] Furthermore, the grinding machine 2 in the prior art is not equipped with a lighting lamp 12 with a safe voltage. The present invention improves the outer cover 3 by installing a lighting lamp 12 with a working voltage below 36V, including 36V, preferably a lighting lamp 12 with a working voltage of 24V.

[0053] In order to further improve safety, a protective cover 13 is further provided on the outer cover 3 corresponding to the upper part of the grinding machine 2. The protective cover 13 is slidably installed on the outer cover 3, and the shielding degree of the grinding machine 2 is adjusted by sliding.

[0054] The protective cover 13 can be installed slidably, and the sliding effect can be used to change the shielding of the grinding machine 2. Under the condition of meeting the work requirements, the grinding machine 2 can be shielded as much as possible, which can improve safety and alleviate the problem of broken grinding wheels splashing and injuring people.

[0055] In the preferred sliding structure, the protective cover 13 is provided with an arc-shaped slide rail 14, and a through hole for bolts to pass through is provided at a position corresponding to the arc-shaped slide rail 14 on the outer cover 3, and the protective cover 13 slides and is tightened by the arc-shaped slide rail 14 and the bolts in the through hole.

[0056] The arc-shaped slide rail 14 enables the protective cover 13 to be rotated and position-adjusted. Figure 1 , 7 As shown in , the protective cover 13 can be rotated using the bolts as the rotating shaft, and the front and rear positions can be adjusted using the arc-shaped slide rails 14. The bolts can be tightened to lock the protective cover 13, so that the protective cover 13 is in a stable installation state after adjustment.

[0057] The arc-shaped slide rail 14 is preferably provided with an arc-shaped through hole, through which bolts can pass and form the function of a slide rail. After the bolts pass through, they can be tightened by nuts, and the structure is simple and practical.

[0058] In order to further improve the safety and convenience of operation, a bracket 15 is further provided on the outer cover 3 below the corresponding grinding machine 2 , and the bracket 15 can be slidably mounted on the outer cover 3 up and down and / or forward and backward.

[0059] The bracket 15 can provide lower support, which is convenient for placing components or hands. The bracket 15 can also provide a certain shielding effect to improve the protection effect. The up and down, front and back sliding of the bracket 15 can make it more adaptable and the protection effect can also be improved.

[0060] In a specific implementation, the following scheme can be adopted to allow the bracket 15 to slide:

[0061] 1. The bracket 15 is provided with a longitudinal slide rail 16, and the outer cover 3 is provided with a horizontal slide rail 17. The longitudinal slide rail 16 and the horizontal slide rail 17 on the bracket 15 are tightened or loosened after passing through bolts, so that the upper and lower or front and rear positions of the bracket 15 can be adjusted and locked by using the bolts as positioning axes.

[0062] 2. The bracket 15 is provided with a horizontal slide rail 17, and the outer cover 3 is provided with a longitudinal slide rail 16. The longitudinal slide rail 16 and the horizontal slide rail 17 are tightened or loosened after passing through bolts, so that the up and down or front and back positions of the bracket 15 can be adjusted and locked by using the bolts as positioning axes.

[0063] The difference between the above two solutions is that the horizontal slide rail 17 and the longitudinal slide rail 16 are provided for different objects.

[0064] It should be noted that the horizontal rail 17 is not completely horizontal, but provides a horizontal movement as a whole. Similarly, the longitudinal rail 16 is not completely longitudinal, but provides a longitudinal movement as a whole.

[0065] The above two solutions refer to Figure 1 , 3 As shown in 6, the horizontal slide rail 17 and the longitudinal slide rail 16 can be set up with bar-shaped through holes, and a bolt is used to pass through the longitudinal slide rail 16 and the horizontal slide rail 17 at the same time, so that the two can move horizontally and longitudinally with the bolt as the positioning axis, thereby providing an upward and downward, front and back adjustment function for the bracket 15; and the bolt can be directly used with the nut to tighten and lock, the structure is simple and the operation is stable and effective.

[0066] Since the grinding wheel will be worn during use, in order to reduce the impact on use, the side of the outer cover 3 is provided with a protective side plate 18 slidably connected thereto, and the protective side plate 18 slides to adjust the degree of shielding of the grinder 2. The sliding direction of the protective side plate 18 can be longitudinally slid along the outer wall of the outer cover 3, or horizontally slid along the outer wall of the outer cover 3, as long as the exposure degree of the grinder 2 can be adjusted by sliding.

[0067] The protective side plate 18 can slide. After the grinding wheel is worn, the protective side plate 18 can be slid to expose the grinding wheel, so as to avoid the parts being blocked when the workers are grinding due to the wear of the grinding wheel, thereby affecting the work.

[0068] And this adjustment function can maintain a good protective effect, and only a required part of the grinding wheel can be exposed through adjustment.

[0069] In order to facilitate assembly and make the structure simpler, limit members 19 are provided on the upper and lower sides of the outer cover 3 corresponding to the protective side panels 18. The limit members 19 are fixedly connected to the outer cover 3, and a gap is formed between the limit members 19 and the outer cover 3 for the protective side panels 18 to be inserted, and the protective side panels 18 slide in the gap.

[0070] The gap between the stopper 19 and the surface of the outer cover 3 is used to provide the sliding of the protective side plate 18, which is simpler in structure and only needs to be fastened by screws during assembly. Of course, welding can also be used for connection.

[0071] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
