Description

[Detailed description of the invention]

[0001]

[Industrial applications]

 In the present invention, the blades to be sharpened are fixed to the double blades 3 and 3a provided in the notch of the main body of the blade sharpening tool by pinching the clamping screw, and the position of the blade and the blade to be sharpened. The present invention relates to a sharpening machine that can adjust the angle to the surface of a donut-shaped rotating grindstone, fix it with a tightening screw, and operate the donut-shaped rotating grindstone with an operating handle to sharpen the blade of the blade.

[0002]

[Prior art]

 A conventional sharpener has a rotating grindstone built into the sharpening machine base.It is placed on the floor or in the soil and rotated, and the blade is held by the hand and attached to the rotating grindstone surface. Not only was it dangerous, but it was also difficult to sharpen a warping blade like a mowing sickle with a conventional sharpening machine because your hands were rough with water and a slag. It is a machine.

[0003]

[Problems to be solved by the device]

 Even craftsmen who use knives sharpen their knives, which is one minute of hard work.In winter, the hands become frozen due to cold water. One example of sharpening a sickle with your hand is to hold the sickle's handle with your foot, receive the back blade with your palm, and hold the whetstone in the other hand and take time to sharpen it. There is no way to sharpen this sickle if you are not used to it, or you can not do it if you are in a situation where you have one hand or a handicapped person, so hold the operation handle with one hand and sharpen the blade with that one hand The above-mentioned drawbacks are to be solved.

[0004]

[Means for Solving the Problems]

 In this invention, the blade to be sharpened is clamped with the clamping screw when two blades are installed in the main body of the blade sharpening machine, the blade position of the blade, the blade angle to be sharpened, and the donut shape. The donut-shaped rotary whetstone is fixed to the surface of the doughnut-shaped rotary whetstone with the tightening screw, and the donut-shaped rotary whetstone that has been lifted is lowered by holding the operation handle and rotated. Attach it to the blade and push the operating handle you have appropriately to rub it to the left or right to sharpen the blade.

[0005]

[Action]

 In the notch of the main body of the sharpening tool base, two chains 3 and 3a of the sharpening tool are provided, and a supporting shaft connecting device for connecting the support shafts 5 and 5a for supporting the sharpening of the sharp tool is provided in the main body of the sharpening machine base. The upper end of the column, which is fixed to the front side of the upper surface and is fixed to the opposite side of the device, is connected to the rotary shaft of the bottom of the U-shaped tool, and the operating shaft connecting tube is laterally placed in the U-shaped metal fitting. Connect the intermediate part and pass the operating shaft through the hollow part of the operating shaft connecting cylinder, insert the operating shaft connecting cylinder into the protruding operating shaft, fit the coil spring 11 on the front side and the 11a on the rear side, and form a snap ring on the front and rear. A metal fitting is fitted and fixed to prevent the coil spring from moving, and further, one ends of the coil springs 11 and 11a are attached to the front and rear of the operation shaft connecting cylinder, and the other ends are attached to the retaining ring fittings fitted to the front and rear of the coil springs 11 and 11a, respectively.

A drive motor is attached to the front side portion of the operation shaft, an operation handle is fixed to the front portion of the operation shaft, and a donner type rotary grindstone is connected to the drive motor. Attached to the rear lower part of the shaft connecting cylinder, the other end is attached to the upper surface of the tool sharpening machine base, the rear part of the column, and the donut-shaped rotary whetstone connected to the drive motor is lifted, the upper surface of the tool sharpening machine base Connected by a water supply pipe to the water outlet, which is located between the bottom of the water tank placed on the table fixed on the right side and the donut-shaped rotary grindstone of the drive motor, put water in the water tank for operation When the handle is lowered, water will come out from the water outlet, and it will enter the plate above the donut-shaped rotary whetstone. Water through the water leak hole However, due to the centrifugal force that falls into the hollow part of the donut-shaped grindstone and rotates, it spreads all over the donut-shaped grindstone.
