[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: The blasting hole crushing device provided by this utility model includes a positioning plate, a first positioning component, a second positioning component, and a driving component; the first positioning component is disposed on the first mounting surface of the positioning plate, and the first positioning component has a first positioning tip; the second positioning component is disposed on the second mounting surface of the positioning plate, and the second positioning component includes at least two sliding positioning elements, which are slidably connected to the positioning plate; the driving component includes a driving rod and a driving blade, the driving rod is rotatably connected to the positioning plate, the driving blade is connected to the driving rod, and the driving blade has a pushing part, which can contact one end of the sliding positioning element and push the sliding positioning element to move away from the center of the positioning plate; the other end of the sliding positioning element has a second positioning tip.
[0020] Analysis shows that the positioning disk provides a base for setting the first positioning component, the second positioning component, and the drive component. Since the first positioning component is set on the first mounting surface of the positioning disk in this application, and it can be understood that the first mounting surface in this application is the bottom surface of the positioning disk, which faces the bottom of the blast hole in actual operation, by setting the first positioning component on the first mounting surface, and the first positioning component in this application having a first positioning tip, the first positioning component can be inserted into the bottom of the blast hole through the first positioning tip, thereby improving the stability of the overall structure.
[0021] Furthermore, since the second mounting surface of the positioning disk in this application is also provided with a second positioning component, and the second positioning component includes at least two sliding positioning elements, which can slide relative to the positioning disk, the driving component in this application includes a driving rod and a driving blade, and the driving rod can rotate relative to the positioning disk, and the driving blade is fixedly connected to the driving rod.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0028] Please see Figure 1-3 This utility model provides a blast hole crushing device, including a positioning disk 1, a first positioning component 2, a second positioning component 3, and a driving component; the first positioning component 2 is disposed on the first mounting surface of the positioning disk 1, and the first positioning component 2 has a first positioning tip 202; the second positioning component 3 is disposed on the second mounting surface of the positioning disk 1, and the second positioning component 3 includes at least two sliding positioning members, which are slidably connected to the positioning disk 1; the driving component includes a driving rod 4 and a driving blade 5, the driving rod 4 is rotatably connected to the positioning disk 1, the driving blade 5 is connected to the driving rod 4, and the driving blade 5 has a pushing part, which can contact one end of the sliding positioning member and push the sliding positioning member to move away from the center of the positioning disk 1; the other end of the sliding positioning member has a second positioning tip 3021.
[0029] Compared with existing technologies, the blast hole crushing device provided by this utility model has the following advantages:
[0030] The blast hole crushing device provided by this utility model provides a base for the first positioning component 2, the second positioning component 3, and the drive component through the positioning plate 1. Since the first positioning component 2 is set on the first mounting surface of the positioning plate 1 in this application, and it can be understood that the first mounting surface in this application is the bottom surface of the positioning plate 1, which faces the bottom of the blast hole in actual operation, by setting the first positioning component 2 on the first mounting surface, and the first positioning component 2 in this application having a first positioning tip 202, the first positioning component 2 can be inserted into the bottom of the blast hole through the first positioning tip 202, thereby improving the stability of the overall structure.
[0031] Furthermore, since the second mounting surface of the positioning disk 1 in this application is also provided with a second positioning component 3, and the second positioning component 3 includes at least two sliding positioning members, which can slide relative to the positioning disk 1, the driving component in this application includes a driving rod 4 and a driving blade 5, and the driving rod 4 can rotate relative to the positioning disk 1. The driving blade 5 is fixedly connected to the driving rod 4. Therefore, when the driving rod 4 rotates, it can drive the driving blade 5 to rotate, thereby using the driving blade 5 to push the sliding positioning member.
[0032] As the sliding positioning component extends, a second positioning tip 3021 is formed at the end of the sliding positioning component away from the drive blade 5. Therefore, the second positioning tip 3021 can penetrate into the side wall of the blast hole, thereby further improving the stability of the overall clamping device. This, in turn, avoids the problem of debris spraying out during blasting to a certain extent, improves the safety of operators, and reduces the environmental pollution caused by the blasting process.
[0033] Optionally, based on the above structure, this application provides one embodiment, such as... Figures 1-3 As shown, in this application, one end of the drive rod 4 is formed with a threaded portion, and a screw hole is formed on the positioning disk 1. The threaded portion and the screw hole are threadedly engaged, so that the drive rod 4 and the positioning disk 1 are detachably connected.
[0034] Since the drive blade 5 is fixedly connected to the drive rod 4 in this application, by forming a threaded portion at one end of the drive rod 4 and forming a threaded hole in the positioning disk 1, a detachable connection between the drive rod 4 and the positioning disk 1 can be achieved by using threaded engagement.
[0035] In actual operation, the drive rod 4 is initially connected to the positioning disk 1. After the positioning disk 1 reaches the bottom of the blast hole and the first positioning tip 202 of the first positioning component 2 is positioned, the drive rod 4 is rotated, which can drive the drive blade 5 to rotate and push the sliding positioning component arranged circumferentially on the positioning disk 1 to move away from the center of the positioning disk 1, thereby enabling the second positioning tip 3021 to penetrate the side wall of the blast hole.
[0036] It is understandable that, such as Figure 2 As shown, since the driving blade 5 in this application is arc-shaped towards the side of the sliding positioning block, the pushing distance of the driving blade 5 is limited. When the most protruding part of the driving blade 5 contacts the sliding positioning block, the driving blade 5 will not push the sliding positioning block further no matter how many more times it rotates. Therefore, when the second positioning tip 3021 enters the side wall, the driving rod 4 can be separated from the positioning disk 1 by continuing to rotate the driving rod 4.
[0037] Since the drive blade 5 is fixedly connected to the drive rod 4, after separation, the operator can directly remove the drive rod 4 and drive blade 5 from the blast hole, leaving only the positioning disc 1 structure inside the hole, which greatly reduces the operating cost of the clamping operation.
[0038] When tightening the next burst hole, simply connect the drive rod 4 to the new positioning disc 1 again. Therefore, only one drive assembly is needed to operate multiple positioning discs 1, greatly reducing usage and manufacturing costs.
[0039] Preferably, such as Figures 1-3As shown, an operating handle 401 is formed at the end of the drive rod 4 away from the positioning disk 1, which is used to rotate the drive rod 4.
[0040] Optionally, such as Figure 1 Combination Figure 3 As shown, the first positioning component 2 in this application includes multiple insert rods, which are evenly distributed in the circumferential direction on the first mounting surface of the positioning disk 1.
[0041] The present application has four insertion rods, which are evenly distributed around the circumference of the positioning plate 1. Furthermore, the center of all the insertion rods is equidistant from the center of the positioning plate 1, thereby ensuring that the positioning plate 1 is subjected to uniform force during insertion, avoiding tilting and improving the protection against gravel.
[0042] It is understandable that, such as Figure 1 Combination Figure 3 As shown, the insert rod in this application includes a column portion 201, one end of which is fixedly connected to the positioning disk 1, and the other end forms a first positioning tip 202.
[0043] Optionally, such as Figures 1-3 As shown, the second positioning component 3 in this application includes a guide block 301 and a sliding block 302. The guide block 301 is disposed on the positioning disk 1, and the sliding block 302 is slidably connected to the guide block 301. One end of the sliding block 302 can contact the drive blade 5, and the second positioning tip 3021 is formed at the other end of the sliding block 302.
[0044] In this application, the guide block 301 is fixedly connected to the positioning disk 1, thereby providing a stable guide for the sliding block 302. Through the sliding connection between the sliding block 302 and the guide block 301, and the fact that the second positioning tip 3021 is formed at the end of the sliding block 302 away from the drive blade 5, when the drive blade 5 pushes the sliding block 302 to move away from the center of the positioning disk 1 relative to the guide block 301, the second positioning tip 3021 can be inserted into the side wall of the blasting channel to achieve further positioning of the positioning disk 1.
[0045] Optionally, in this application, the guide block 301 near the edge of the positioning disk 1 and facing the sliding block 302 has an elastic locking member formed on its side. The sliding block 302 away from the second positioning tip 3021 and facing the sliding block 302 has a locking hole. When the sliding block 302 is pushed to the limit position by the drive blade 5, the elastic locking member can extend into the locking hole, so that the sliding block 302 and the guide block 301 are fixed in position.
[0046] The elastic snap-fit component in this application can be a ball or a positioning pin protruding from the guide block 301. Since the positioning disc 1 in this application ultimately remains in the rupture hole, a positioning pin structure with more stable positioning is preferred. That is, a spring is provided inside the guide block 301, one end of the positioning pin is connected to the spring, and the other end extends out under the action of the spring.
[0047] Since the sliding block 302 has a locking hole at the corresponding position, when the sliding block 302 slides into position relative to the guide block 301, the positioning pin is further ejected under the action of the spring, thereby entering the locking hole and locking the position between the sliding block 302 and the guide block 301.
[0048] It is understandable that, since this application only needs to ensure that the sliding block 302 will not retract after the second positioning tip 3021 of the sliding block 302 pierces the side wall of the blast hole, causing the second positioning tip 3021 to detach from the side wall of the blast hole, the use of a positioning pin can make the limiting more stable.
[0049] Preferably, such as Figures 1-3 As shown, the number of sliding blocks 302 in this application is four, and the four sliding blocks 302 are evenly distributed along the circumference of the positioning disk 1. The guide block 301 corresponds one-to-one with the sliding block 302, and the number of driving blades 5 is at least two.
[0050] More preferably, the number of drive blades 5 in this application is four, which can push the sliding block 302 to complete the action more quickly. Although a single blade can also achieve the action, the force is relatively unstable. Therefore, at least two drive blades 5 are required. Correspondingly, the more blades there are, the fewer rotations the drive rod 4 will make, but the cost and overall weight will increase relatively.
[0051] Another embodiment provided in this application is that the drive rod 4 and the positioning disk 1 are an integral structure. In this embodiment, a mounting hole is formed in the center of the positioning disk 1, and a bearing is provided in the mounting hole. One end of the drive rod 4 is fixedly connected to the inner ring of the bearing.
[0052] In some embodiments, since the depth of the blast holes is different, the drive rod 4 in this application may include multiple rod sections that are detachably connected, and an operating handle 401 is formed on the rod section located away from the positioning disk 1.
[0053] The detachable connection of multiple rod sections can be achieved using threaded engagement or other snap-fit engagement methods, which will not be elaborated here. By setting multiple detachable rod sections, the overall length of the drive rod 4 can be increased or decreased according to specific needs, thereby enabling better construction.
[0054] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
