DETAILED DESCRIPTION

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention, so as to have a further understanding of the concept of the present invention, the technical problems solved, the technical features constituting the technical solutions and the technical effects brought about.

[0021] like Figure 1 、 Figure 2As shown, a blasting hole cleaning device includes a device body 1 and a telescopic cylinder 2, and a motor 3 is installed on the output end of the telescopic cylinder 2; it also includes a cleaning rotating rod 4, one end of the cleaning rotating rod 4 is connected to the output end of the motor 3, and the other end of the cleaning rotating rod 4 is installed with a stone crushing cone 41, and the cone surface of the stone crushing cone 41 is provided with a threaded protrusion; more than two fixing plates 43 are installed on the side of the cleaning rotating rod 4, and the fixing plates 43 are connected to the scraper through the telescopic rod 44, and the telescopic rod 44 is provided with a fixing knob; it also includes a support frame installed on the device body 1, and the support frame includes a first support bar 5, and both ends of the first support bar 5 are provided with a first threaded hole, and a support rod 7 is installed in the first threaded hole, and the bottom of the support rod 7 is installed with a fixing plate 9 through a bearing seat 8.

[0022] During blasthole cleaning, the present invention places the main body 1 of the device above the blasthole, controls the telescopic cylinder 2 to adjust the height of the cleaning rod 4, places the cleaning rod 4 within the blasthole, and rotates the cleaning rod 4 using the motor 3. The rotation drives the crushing cone 41 and the scraper to rotate and clean the hole. The crushing cone 41 utilizes the rotation of its conical surface, and the telescopic cylinder 2 continuously presses the conical surface of the crushing cone 41 downward during operation. The crushing cone 41, in conjunction with the threaded protrusions on the conical surface of the crushing cone 41, crushes accumulated rocks within the blasthole. The scraper cleans the blasthole wall, preventing the detonator from becoming stuck in the hole during placement, thus avoiding safety accidents and ensuring construction safety. The present invention is fixed via a support frame. Since the support rods 7 at both ends of the first support bar 5 are threadedly connected to the first support bar 5, the height can be adjusted by rotating the support rods 7. A fixing plate 9 is placed on the ground outside the blasthole to secure the main body of the device.

[0023] Furthermore, the support frame also includes a second support bar 6; a mounting slot is provided at the bottom of the first support bar 5, and the second support bar 6 is rotatably connected to the bottom of the first support bar 5. Second threaded holes are provided at both ends of the second support bar 6, and support rods 7 are installed in the second threaded holes. A fixing plate 9 is installed at the bottom of the support rod 7 through a bearing seat 8. The two-end fixing method used by the device body 1 is not stable enough. The second support bar 6 is rotatably connected to the mounting slot at the bottom of the first support bar 5. During installation, the second support bar 6 can be rotated and unfolded, thereby forming a cross-shaped support system with the first support bar 5, achieving a more stable support effect.

[0024] Furthermore, first fixing blocks 51 are provided at both ends of the first support bar 5, and second fixing blocks 61 are provided at both ends of the second support bar 6. The first fixing blocks 51 and the second fixing blocks 61 are connected by bolts. Notches are provided at both ends of the first support bar 5 for receiving the support rods 7 at both ends of the second support bar 6. The provision of the first fixing blocks 51 and the second fixing blocks 61 allows the first and second support bars 5, 6 to be locked when they are retracted, preventing them from swinging.

[0025] like Figure 3 As shown, the fixing plate 9 to which the first support bar 5 and the second support bar 6 are mounted is provided with a plurality of fixing holes, and the bottom of each fixing plate 9 is provided with an anti-slip pad 10. The provision of the anti-slip pad 10 improves the stability of the present invention. If the device body cannot stand upright, bolts are passed through the fixing plate 9 to fix the device body 1 to the ground to prevent the device body from tilting.

[0026] like Figure 4 As shown, further, the side of the cleaning rotating rod 4 is provided with two or more side grooves 42, and the fixing piece 43 is installed in the side groove 42 of the cleaning rotating rod 4. The side groove 42 is provided, and the fixing piece 43 is installed in the side groove 42. During the rotation of the scraper 45, the side of the fixing piece 43 abuts against the inner wall of the side groove 42, which can support the scraper 45.

[0027] The words "connection" and "fixation" appearing in the description of the present invention may refer to fixed connection, processing and forming, welding, or mechanical connection. The specific meanings of the above terms in the present invention shall be understood according to the specific circumstances.

[0028] In the description of the present invention, the terms "center", "upper", "lower", "horizontal", "inner", "outer", etc., which indicate the orientation or position relationship, are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation. Therefore, they cannot be understood as limitations on the present invention.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that the technical solutions described in the above embodiments can still be modified, or some or all of the technical features therein can be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
