DETAILED DESCRIPTION

[0025] The following is a description of the implementation of the present invention by means of specific embodiments. People familiar with the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification.

[0026] See also Figures 1 to 4 . It should be noted that the structures, proportions, sizes, etc. illustrated in the drawings of this specification are only used to match the contents disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the limiting conditions for the implementation of the utility model, so they have no substantial technical significance. Any modification of the structure, change in the proportional relationship, or adjustment of the size, without affecting the effects and purposes that can be achieved by the utility model, should still fall within the scope of the technical content disclosed by the utility model. At the same time, the terms such as "upper", "lower", "left", "right", "middle" and "one" quoted in this specification are only for the convenience of description, and are not used to limit the scope of the implementation of the utility model. Changes or adjustments in their relative relationships should also be regarded as the scope of the implementation of the utility model without substantially changing the technical content.

[0027] The following embodiments are only for illustration purposes and can be combined with each other, and are not limited to the contents presented in the following single embodiments.

[0028] For this example, please refer to Figure 1-4 The utility model provides an embodiment of a blasthole landfill device for open-air blasting, comprising a mounting base plate 51, a telescopic rod 52 and a chipping board 53; a rotating connection portion 511 is provided on the mounting base plate 51, and a shaft rod perpendicular to the ground is provided on the rotating connection portion 511, one end of two chipping boards 53 are both rotatably connected to the shaft rod, and the two ends of the telescopic rod 52 are respectively hinged on the mounting base plate 51 and the chipping board 53 and adjust the relative opening angle of the two chipping boards 53; a contact detection unit 5111 is provided on the rotating connection portion 511, and the contact detection unit 5111 is located in the middle of the two chipping boards 53, and the contact detection unit 5111 is triggered when the two chipping boards 53 are closed to the minimum angle.

[0029] In the above embodiment, when filling the blasthole, the two planing boards 53 are first opened into a "V" shape and then moved forward, so that the soil pile around the blasthole enters the middle of the two planing boards 53, and then the telescopic rod 52 pushes the two planing boards 53 to close, and then the blasthole filling device moves back and forth as a whole, so that the soil pile falls from the blasthole, thereby achieving the purpose of blasthole filling, which has the characteristics of high efficiency and reduced labor intensity.

[0030] Furthermore, the two planing boards 53 are rotatably connected to the same shaft or are rotatably connected to two adjacent shafts. When connected to the same shaft, the two planing boards can be connected to different positions of the shaft; when connected to two shafts, they can be connected as follows: Figure 1 As shown, two adjacent shafts are provided.

[0031] This embodiment can be found in Figure 2 , the detection heads 51111 of the contact detection unit 5111 are arranged on both sides and are respectively opposite to the two planing boards 53. In specific implementation, the detection heads 51111 can be a push switch or a proximity sensor. It should be noted that the contact detection unit 5111 is not necessarily provided, but is only used as a better implementation method. Because during specific construction, the blasthole filling device is often installed in front of a large engineering machinery, and its operating height is relatively low, so in actual implementation, the driver of the engineering machinery has a limited field of vision, and it is difficult to fully observe the state of the blasthole filling device, and it is also difficult to grasp the size when operating the telescopic rod 52. Setting the detection head 51111 can limit the stroke of the planing board 53. Once the two planing boards 53 reach the minimum clasping state, the two detection heads 51111 are also activated. At this time, even if the operator continues to operate the planing board 53 to continue clamping, the telescopic rod 52 and the planing board 53 will not continue to move, thereby improving the stability and safety of the device and facilitating the operator's operation.

[0032] For this example, please refer to Figure 3 The chipping board 53 includes a first board 531 and a second board 532 connected at an obtuse angle. When the two chipping boards 53 are folded and fitted together, a closed accommodation space is formed inside to accommodate the soil pile. When the chipping boards 53 move forward and backward to push the soil pile into the blasthole, the soil pile is always kept in the two chipping boards 53 and will not flow out, thereby ensuring the effect of filling the blasthole.

[0033] Furthermore, the end of the planing board 53 is also connected to a third board 533. When the two planing boards 53 are closed to the minimum angle, the ends of the two third boards 533 touch each other. In this embodiment, the planing board 53 formed by three boards has a concave shape. The concave parts of the two planing boards 53 are opposite to each other. When the two planing boards 53 are closed, the concave space inside is larger, which can accommodate more blasthole soil piles, can be applied to more blasthole types, and has a better blasthole landfill effect.

[0034] Furthermore, a transverse fourth plate 534 is provided at the upper end of the planing board 53. When the two planing boards 53 are closed to the minimum angle, there is still a gap between the fourth plates 534 on the two planing boards 53. The fourth plate 534 can strengthen the strength of the planing board 53. When the two planing boards 53 are closed, the position between the two fourth plates 534 is the foot line area of ​​the detonator, which can prevent the planing board 53 from clamping off the detonator foot line when filling the blast hole, causing difficulties for subsequent construction.

[0035] like Figure 4 As shown, this embodiment is an embodiment of a blasthole landfill vehicle for open-pit blasting, including the blasthole landfill device as described above, and also including a walking chassis, and the blasthole landfill device is installed at the front end of the walking chassis. The walking chassis is driven by wheels or tracks. When the walking chassis is driven by tracks, it includes a main track 551 and an auxiliary track 552, two main tracks 551 are arranged at the bottom of the walking chassis to drive walking, and two auxiliary tracks 552 are respectively arranged on both sides of the walking chassis near the front, and one end of the auxiliary track 552 is rotatably connected to the walking chassis, and the other end faces the forward direction of the walking chassis and the angle is adjustable. The auxiliary track 552 can rotate at a certain angle relative to the ground, and has a strong passing ability for earth pits and earth bags, so as to cope with the complex geological environment in the open-pit mine scene and increase the applicability and applicable scenes of the work vehicle.

[0036] In summary, the utility model effectively overcomes various shortcomings in the prior art, can produce beneficial technical effects, and has significant progress.

[0037] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed in the present invention shall still be covered by the claims of the present invention.
