The lower end is connected with a scraper seat, and a plurality of scrapers are arranged on the scraper seat; the wire take-up wheel is fixedly connected with the driven wheel, the driven wheel is engaged with the driving wheel, and the driving wheel is arranged on the output shaft of the wire take-up motor; the A traveling wheel is arranged below the frame, and the axle of the traveling wheel rotates coaxially with the output shaft of the traveling motor.

The scraper seat comprises a body, one end of the body is provided with a front end, the front end is provided with a lifting lug, and the lifting lug is connected with the sling; the other end of the body is provided with a rear end; connected to the screw hole on the axial end face of the main body; the main body is provided with an axial slot hole, a knife holder insert plate is arranged in the slot hole, and a knife hole is arranged on the guide frame insert plate, after the scraper is inserted into the knife hole, Insert the adjustment plate to ensure the smooth surface of the blade holder insert plate; the vertical section of the bottom of the scraper is a trapezoid, and the vertical section of the knife hole is a corresponding trapezoid, and the two cooperate to ensure that the scraper is radially fixed; the slot hole is Wedge-shaped, the blade holder is also wedge-shaped accordingly.

The walking motor and the wire take-up motor are both connected with the motor controller, and the motor controller is connected with the PLC.

The PLC is also connected with a remote control host through a communication module.

The advantage of the invention is that the scraper is inserted into the surface of the adhered mineral powder by the gravity of the scraper seat, and under the pulling force of the rope, the scraper moves continuously on the surface of the mineral powder, and the scraped mineral powder falls into the outlet at the bottom of the silo. The traveling carriage ensures that the powder scraping operation can be carried out along the entire edge of the silo; therefore, it is not only time-saving and labor-saving, but also safe and reliable.

Detailed ways

The present invention will be described in detail below with reference to the accompanying drawings. As shown in the figure, the present invention includes a track 2 arranged on the edge of the mine silo 1, a traveling vehicle is arranged on the track 2, and a wire take-up wheel 7 is arranged on the frame 3 of the traveling vehicle. The cable 8 is wound on the take-up pulley 7, and the lower end of the sling 8 is connected to the scraper seat 9, and a plurality of scrapers 10 are arranged on the scraper seat 9; the take-up pulley 7 is fixedly connected with the driven wheel 71, and the The driven wheel 71 is meshed with the driving wheel 61, and the driving wheel 61 is arranged on the output shaft of the take-up motor 6; the traveling wheel 4 is arranged under the frame 3, and the wheel shaft of the traveling wheel 4 rotates coaxially with the output shaft of the traveling motor 5 .

The scraper holder 9 includes a main body 903, one end of the main body 903 is provided with a front end 901, and the front end is provided with a lifting lug 904, which is connected with the sling 8; the other end of the main body is provided with a rear end 902; Bolts 905 are provided, and the bolts are screwed into the screw holes on the axial end face of the main body; the main body is provided with an axial slot 906, a tool holder insert plate 907 is arranged in the slot hole, and a tool hole is arranged on the guide holder insert plate 908, after the scraper 909 is inserted into the knife hole, then insert the adjustment plate 910 to ensure the smoothness of the contact surface between the knife holder insert plate and the slot hole; the vertical section of the bottom of the scraper is trapezoidal, and the vertical section of the knife hole is corresponding Trapezoid, the two cooperate to ensure the radial fixation of the scraper; the slot hole is wedge-shaped, and the blade holder insert plate is correspondingly wedge-shaped. The front end and the rear end are both conical, and the body is cylindrical; in this way, the combination of the three forms a shuttle shape, which can reduce the resistance of the scraper during movement and ensure that the tool holder body will not accumulate mineral powder.

Since the external force is from the front end to the rear end of the body during use, in order to prevent the tool holder inserting plate from moving, the slot hole is wedge-shaped, and the width near the front end is greater than that near the rear end. The plates are correspondingly wedge-shaped.

A plurality of scrapers are arranged on the insert board of each blade holder, 3 scrapers in this embodiment, and 2, 4, and 5 scrapers can also be arranged according to actual needs.

Slot holes are evenly arranged on the main body along the circumferential direction of the circle. Preferably, six slot holes are provided, and the radial direction of each slot hole passes through the axis of the body, that is, the central angle of two adjacent slot holes is 60 degrees.

Another arrangement of scrapers is: the scrapers are arranged in a spiral shape on the surface of the body; the advantage of this arrangement is that the rotating force formed when the scraper is under force can be used to drive the body to rotate, so that the scrapers at all angles on the body are in contact with the mine. Powder contact to achieve better technical effect;

In order to realize automatic control, the traveling motor 5 and the wire take-up motor 6 are both connected to the motor controller, and the motor controller is connected to the PLC. Both the PLC and the motor controller can be commercially available products.

In order to realize remote control, the PLC is also connected with the remote control host through a communication module, and the communication module here can be a general module based on the Internet.

The present invention utilizes the gravity of the scraper seat 9 to make the scraper 10 insert into the surface of the adhered mineral powder 11. Under the pulling force of the rope 8, the scraper moves continuously on the surface of the mineral powder, and the scraped mineral powder falls into the outlet 12 at the bottom of the ore bin. The traveling carriage ensures that the powder scraping operation can be carried out along the entire edge of the silo; therefore, it is not only time-saving and labor-saving, but also safe and reliable.
