[0043] Working principle: This conveying equipment constant pressure sweeper, when used:

[0044] Step 1, install the three above-mentioned sweepers to the end of the conveyor belt, first pre-drill holes in the corresponding installation positions and weld the corresponding supports, install the whole machine at the corresponding position, and the set installation position should be calculated to make the scraper 210 protrude 12-20mm relative to the upper surface of the guide plate 102, and push the rectangular steel pipe 101 to rotate by adjusting the bolt four 305, adjust the deflection angle of the whole machine support frame device 1, so that the end face of the scraper 210 fits the tape, tighten the bolt three 303 to tighten the rectangular steel pipe 101, so that the rectangular steel pipe 101 does not rotate, tighten the nut 304 to press the outer cylindrical surface of the support adjustment seat 301 to prevent the bolt three 303 from loosening;

[0045] Step 2, press the start button on the two controllers 401 on both sides, the electric push rod 201 extends, the electric push rod 201 pushes the spring seat 1 204 to move along the track plate 104, compresses the spring 205, and the spring 205 pushes the spring seat 206 to move and squeeze the pressure sensor 207. The bottom of the pressure sensor 207 pushes the slider 208 to move, and the slider 208 drives the tool holder 209 to move up and down. The tool holder 209 drives the scraper 210 to move and press the tape. As the electric push rod 201 continues to extend, the spring 205 is compressed, and the pressure between the spring seat 206 and the pressure sensor 207 gradually increases. The pressure between the scraper 210 and the tape increases synchronously. When the preset pressure value of the pressure sensor 207 is reached, the pressure sensor 207 feeds back a signal to the controller 401, and the controller 401 controls the electric push rod 201 to stop extending;

[0046] Step 3, when the scraper 210 and the tape are gradually worn, as the pressure of the pressure sensor 207 decreases, the controller 401 controls the electric push rod 201 to extend, and when the preset pressure value of the pressure sensor 207 is reached, the pressure sensor 207 feeds back a signal to the controller 401, and the controller 401 controls the electric push rod 201 to stop extending;

[0047] Step 4, looping step 3, when the tool holder 209 contacts the limit pin 5, the tool holder 209 cannot extend further due to the limitation of the limit pin 5, and when the pressure sensor 207 reaches the preset pressure value, the pressure sensor 207 feeds back a signal to the controller 401, and the controller 401 controls the electric push rod 201 to stop extending. In this state, the scraper 210 needs to be replaced;

[0048] Step 5: The operator loosens the nut 304, the bolt three 303 and the bolt four 305, deflects the whole machine support frame device 1 to facilitate the replacement of the scraper 210 position, pulls out the worn scraper 210, and inserts a new scraper 210;

[0049] Step 6, press the tool change button on the controller 401, the controller 401 controls the electric push rod 201 to retract, at this time, press the scraper 210 down, push the rectangular steel pipe 101 to rotate by adjusting the bolt four 305, adjust the deflection angle of the whole machine support frame device 1, make the end face of the scraper 210 fit with the tape, tighten the bolt three 303 to press the rectangular steel pipe 101, so that the rectangular steel pipe 101 does not rotate, tighten the nut 304 to press the outer cylindrical surface of the support adjustment seat 301 to prevent the bolt three 303 from loosening;

[0050] Step 7: Repeat steps 2 to 6.
