Technical Field
[0001] The utility model relates to the technical field of grinding, in particular to a portable grinding machine. Background Art
[0002] The rods, links between rods and the entire derrick of the drilling rig mast have various degrees of damage, and the derrick bearing capacity needs to be regularly inspected and safety assessed. The strain test in the derrick bearing capacity assessment requires the installation of strain gauges or sensors at key positions of the derrick rods, which must be polished, rusted and depainted before installation. Currently, the most commonly used tool to complete this process is a file. The disadvantage of this tool is that the inspector needs to use a file to polish the derrick rods with one hand on the derrick about 40 meters above the ground, which is very physically demanding. At the same time, the inspector must always be vigilant against the file in his hand falling from a height and injuring the staff below. A small number of inspectors have begun to use portable grinders to grind the derrick rods.
[0003] A major disadvantage of existing portable grinders is that they are large in size, heavy in weight, and have no fall protection device.
[0004] For example, the portable grinder disclosed in Chinese patent publication number CN205703638U has a hand-held handle at the bottom of the main housing, which makes the utility model smaller and lighter, easier to carry and store, and can effectively reduce the labor intensity for inspectors working at heights; the handle of the grinder is a hand-held handle with a protective finger ring outside the handle, and an adjustable rope at the rear of the main housing for wrapping around the wrist, and the dual protection of the protective finger ring and the adjustable rope can effectively prevent the grinder from falling from a height.
[0005] However, the grinder is not provided with a chip removal structure, so that the chips generated during grinding cannot be collected, resulting in the chips flying everywhere and being difficult to clean up.
[0006] For this reason, we urgently need to provide a portable grinder with chip removal function. Utility Model Content
[0007] The utility model aims to provide a portable grinder to solve the problem that the grinder proposed in the above background technology has no chip removal structure, so that the chips generated during grinding cannot be collected, resulting in the chips flying around and being difficult to clean up.
[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a portable grinder, comprising a grinder housing and an end cover, the end cover being hinged to the upper side of the grinder housing by a hinge, the inner and outer ends of the grinder housing being connected with a grinding mechanism, the grinding mechanism comprising a grinding unit and an adjustment unit, the grinding unit being arranged at the inner and outer ends of the grinder housing, and the adjustment unit being arranged at the right end of the grinder housing.
[0009] The grinding unit includes a motor, a sanding head, a chip suction bucket, a material receiving box, a fan, a connecting pipe, a cover and a filter. The motor is fixedly connected to the inner left bottom end of the grinder housing, the sanding head is fixedly connected to the lower end of the output shaft of the motor, the chip suction bucket is fixedly connected to the lower side of the grinder housing and is located at the outer end of the sanding head, the material receiving box is fixedly connected to the middle position of the inner bottom end of the grinder housing, the fan is fixedly connected to the inner bottom end of the grinder housing and is located to the right of the material receiving box, the connecting pipe is fixedly connected to the middle position below the inner left end of the material receiving box, the cover is hinged to the upper side of the material receiving box by a hinge, and the filter is vertically fixedly connected to the inner right end of the material receiving box.
[0010] A further improvement is that a ventilation hole is provided at the middle position below the right end of the inside of the material receiving box, the right side of the material receiving box is fixedly connected to the air inlet outside the fan at the ventilation hole, and the end of the connecting pipe away from the material receiving box is fixedly connected to the upper right end of the inside of the chip suction hopper. Thus, starting the fan can evacuate air from the material receiving box, so that the debris generated by the sanding head during grinding will be sucked from the chip suction hopper, then enter the connecting pipe and then enter the material receiving box, thereby absorbing the debris during grinding.
[0011] A further improvement is that the upper end of the filter screen abuts against the lower side of the filter screen, so that the debris entering the material receiving box will be filtered out by the filter screen and will not enter the fan through the ventilation hole.
[0012] A further improvement is that the adjustment unit includes a sleeve rod, a grip rod, a spring and an insertion rod, the sleeve rod is fixedly connected to the right side of the grinder housing, the grip rod is slidably connected to the inner side of the sleeve rod, the spring is connected to the inner left end of the grip rod, and the insertion rod is fixedly connected to the lower end of the spring.
[0013] A further improvement is that a circular groove is provided at the lower left end of the handle, the upper end of the spring is fixedly connected to the upper end of the inner side of the circular groove, and the outer side of the insertion rod is slidably connected to the inner side of the circular groove. Therefore, when the spring is activated, the insertion rod can be driven to slide along the inner side of the circular groove, thereby limiting the movement of the insertion rod.
[0014] A further improvement is that the lower end of the sleeve rod is provided with insertion holes at equal distances, and the outer side of the lower end of the insertion rod is plugged into the inner side of the insertion holes. Thus, after the grip rod is slid along the inner side of the sleeve rod, the insertion rod is pushed down by the spring rebound, so that the lower end of the insertion rod moves to the insertion hole at the corresponding position, and the grip rod can be fixed to the inner side of the sleeve rod, so that the overall length of the sleeve rod and the grip rod can be adjusted and fixed, so that the grinder can be extended to a farther position for grinding, thereby improving the work safety of the staff.
[0015] A further improvement is that a rubber pad is fixedly connected to the upper side of the filter screen, so that after the cover is fixed to the upper side of the material receiving box, the rubber pad on the upper side of the filter screen contacts the lower side of the filter screen, so that the contact between the filter screen and the cover can be kept sealed, preventing debris from directly entering the right end of the inner part of the material receiving box without being filtered by the filter screen and then entering the ventilation hole.
[0016] In summary, the present application discloses a portable sander.
[0017] This technical solution can start the fan to exhaust air in the material collection box, so that the debris generated by the sanding head during grinding will be sucked into the chip suction hopper, then enter the connecting pipe and then enter the material collection box, thereby absorbing the debris generated during grinding.
[0018] Furthermore, after the grip rod is slid along the inner side of the sleeve rod, the insertion rod is pushed down by the spring rebound, so that the lower end of the insertion rod moves to the socket at the corresponding position, so that the grip rod can be fixed to the inner side of the sleeve rod, so that the overall length of the sleeve rod and the grip rod can be adjusted and fixed, so that the grinder can be extended to a farther position for grinding, thereby improving the work safety of the staff.
