Description

Technical Field

[0001] The utility model relates to the technical field of protective covers, and particularly relates to a motor protective cover device for an iron sample grinding machine. Background Art

[0002] In the iron coke working area of the quality measurement center, a horizontal grinding machine is used to grind molten iron samples. The motor of the grinding machine is vertical, and a grinding wheel is connected to the lower end to process the samples. The upper end of the motor is a square mesh hole with a side length of 5*5 mm for heat dissipation.

[0003] In the process of implementing this solution, the inventor found that the following problems in the prior art have not been well solved: Since the grinding machine operates continuously for 24 hours, during the process of grinding molten iron samples, first, iron filings, dust, etc. are easily sucked into the motor through the square holes, causing the motor to burn out; second, due to the large aperture of the square holes, during the operation of inspectors, safety problems such as hair being caught are likely to occur. Content of the Utility Model

[0004] The main purpose of the utility model is to provide a motor protective cover device for an iron sample grinding machine, which can effectively solve the problems in the background art.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A motor protective cover device for an iron sample grinding machine includes a motor body. A plurality of square holes are drilled in the motor body. A protective cover is arranged outside the motor body at the position of the square holes. Three iron sheet ears are evenly fixed at the bottom of the protective cover. Screws are arranged on the outer walls of the motor body at the ends of the iron sheet ears far from the protective cover. Nuts are threadedly connected to the outer walls of the screws. Arc-shaped vertical plates are fixed at the bottom of the protective cover between adjacent iron sheet ears. Through grooves are drilled in the side walls of the arc-shaped vertical plates. Arc-shaped horizontal plates are fixed at the top and bottom of the outer side walls of the arc-shaped vertical plates at the positions of the through grooves. Arc-shaped magnetic pieces are fixed at the ends of two mutually perpendicular arc-shaped horizontal plates close to each other.

[0007] Preferably, the screws are respectively welded to the motor body. The ends of the screws far from the motor body respectively penetrate through and communicate with the iron sheet ears in a matching position. The nuts are respectively located on the sides of the iron sheet ears far from the motor body.

[0008] Preferably, the height dimension of the arc-shaped vertical plate is greater than the distance between the bottom of the protective cover and the top of the motor body.

[0009] Compared with the prior art, the utility model has the following beneficial effects:

[0010] By adding a protective cover at the heat dissipation holes of the motor body, the protective cover can prevent the safety hazard caused by the staff's hair being directly sucked into the motor interior, and at the same time can block most of the excessive dust. When the motor body dissipates heat through the heat dissipation holes, the air will enter through the through grooves of the arc-shaped vertical plates and between the two arc-shaped horizontal plates. When flowing between them, it will be filtered by the arc-shaped magnetic pieces between the two arc-shaped horizontal plates. The two arc-shaped magnetic pieces can adsorb the iron filings flowing through, avoiding entering the interior of the motor body and causing equipment burnout, which plays a good protective effect on the motor body.

[0015] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further elaborated below in conjunction with specific embodiments.

[0016] As Figures 1 - 3 shown, a motor protective cover device for an iron sample grinding machine includes a motor body 1. A number of square holes are drilled in the motor body 1. A protective cover 2 is provided outside the motor body 1 at the position of the square holes. Three iron sheet ears 3 are fixedly arranged at equal intervals at the bottom of the protective cover 2. Screws 4 are provided on the outer walls of the motor body 1 at the ends of the iron sheet ears 3 away from the protective cover 2. Nuts 5 are threadedly connected to the outer walls of the screws 4. Arc-shaped vertical plates 6 are fixedly arranged at the bottom of the protective cover 2 between adjacent iron sheet ears 3. Through grooves 7 are drilled on the side walls of the arc-shaped vertical plates 6. Arc-shaped horizontal plates 8 are fixedly arranged at the top and bottom of the outer side walls of the arc-shaped vertical plates 6 at the positions of the through grooves 7. Arc-shaped magnetic pieces 9 are fixedly arranged at the ends of the two perpendicular arc-shaped horizontal plates 8 close to each other.

[0017] Specifically, the screw rod 4 is respectively welded to the motor body 1. One end of the screw rod 4 away from the motor body 1 respectively penetrates through and communicates with the iron sheet ears 3 with matching positions. The nuts 5 are respectively located on the side of the iron sheet ears 3 away from the motor body 1, so that the protective cover 2 can be disassembled and assembled with the motor body 1.

[0018] Specifically, the height dimension of the arc-shaped vertical plate 6 is greater than the distance between the bottom of the protective cover 2 and the top of the motor body 1, so that when air circulates, iron filings in the air can be adsorbed to a greater extent by the arc-shaped magnetic sheet 9.

[0019] Working principle:

[0020] By adding a protective cover 2 at the heat dissipation holes of the motor body 1, the protective cover 2 can prevent the safety hazard caused by the staff's hair being directly sucked into the motor interior, and at the same time can block most of the dust. When the motor body 1 dissipates heat through the heat dissipation holes, air will enter through the through groove 7 of the arc-shaped vertical plate 6 and between the two arc-shaped horizontal plates 8. When flowing between them, it will be filtered by the arc-shaped magnetic sheet 9 between the two arc-shaped horizontal plates 8. The two arc-shaped magnetic sheets 9 can adsorb the iron filings flowing through, avoiding entering the interior of the motor body 1 and causing damage to the equipment, and playing a good protective effect on the motor body 1.

[0021] The circuits, electronic components and control modules involved are all existing technologies, which can be fully realized by those skilled in the art. Without further elaboration, the content protected by the present utility model does not involve improvements to software and methods.
