[0002] At present, in the engineering industry, there are often more reinforced concrete demolition operations, such as the demolition of buildings and structures that have expired, or the demolition of temporary buildings and structures for auxiliary use. Large demolition projects often use blasting demolition first, and then use a blasting machine for more delicate secondary processing. Small buildings and structures are directly demolished by blasting machines and more delicate secondary processing is used to facilitate loading and transportation. At the same time, in demolition projects, there are often a large number of scrap steel bars that need to be sorted and collected after the demolition of buildings and structures. The blasting machine of the conventional blasting machine head often cannot completely separate the scrap steel bars and concrete, and some concrete is still firmly bonded to the steel bars. It is also necessary to use an electric drill to assist in demolition, which is time-consuming and laborious. Moreover, after demolition, the steel bars are often of different shapes and extremely irregular. Conventional blasting machines cannot compress and collect them, which is not conducive to loading and transportation, and often requires a large amount of manual participation.

[0024] At present, in the engineering industry, there are often more reinforced concrete demolition operations, such as the demolition of buildings and structures that have expired, or the demolition of temporary buildings and structures for auxiliary use. Large demolition projects often use blasting demolition first, and then use a blasting machine for more delicate secondary processing. Small buildings and structures are directly demolished by blasting machines and more delicate secondary processing is used to facilitate loading and transportation. At the same time, in demolition projects, there are often a large number of scrap steel bars that need to be sorted and collected after the demolition of buildings and structures. The blasting machine of the conventional blasting machine head often cannot completely separate the scrap steel bars and concrete, and some concrete is still firmly bonded to the steel bars. It is also necessary to use an electric drill to assist in demolition, which is time-consuming and laborious. Moreover, after demolition, the steel bars are often of different shapes and extremely irregular. Conventional blasting machines cannot compress and collect them, which is not conducive to loading and transportation, and often requires a large amount of manual participation. Therefore, the inventor has improved the design of the blasting machine head in view of the shortcomings of the above conventional blasting machines in steel concrete processing and compression, collection and arrangement of scrap steel bars.

[0025] Based on this, the present application proposes a gun machine gun head, Figures 1 to 3 As shown, it includes a gun head body 1 and a gun head connecting member 2, and the gun head connecting member 2 is fixedly connected to the center position of the upper surface of the gun head body 1. Specifically, the center position of the upper surface of the gun head body can be a position near the geometric center of the upper surface of the gun head body 1, or a position near the symmetric center of the upper surface of the gun head body 1. The gun head connecting member 2 includes a first connecting plate 21 and a second connecting plate 22, the first connecting plate 21 and the second connecting plate 22 are arranged parallel to each other, and a first pin shaft 31 and a second pin shaft 32 are arranged between the first connecting plate 21 and the second connecting plate 22, and the gun head body 1 can rotate relative to the first pin shaft 31 and the second pin shaft 32. The first connecting plate 21 and the second connecting plate 22 are connected to the gun head body 1 in a straight surface, and the first connecting plate 21 and the second connecting plate 22 are opposite to the connecting portion of the gun head body 1. The first connecting plate 21 and the second connecting plate 22 are curved surfaces on the side away from the connecting portion of the gun head body 1. The curved surface is high at both ends and low in the middle. The concave design in the middle can facilitate the avoidance of other structures during the rotation of the gun head body 1. The main body 1 of the gun head is in the shape of a round pancake, and at least three tooth rakes 4 are arranged on the lower surface of the main body 1 of the gun head. The three tooth rakes 4 are arranged at intervals near the edge of the lower surface of the gun head 1. The design of at least three tooth rakes 4 can be used to remove concrete slag and find scrap steel bars on the one hand, and can assist in removing concrete attached to a single steel bar on the other hand, and can be used to rake and collect scrap steel bars. A strong magnetic component (not shown in the figure) for adsorbing steel bars is arranged in the main body 1 of the gun head (not shown in the figure). The building is disassembled and separated by the wide force-bearing area of ​​the lower surface of the main body 1 of the round pancake, and the scrap steel bars of various shapes are rolled into a ball, and then the scrap steel bars are directly adsorbed by the strong magnetic component arranged in the main body 1 of the gun head, which greatly improves the construction efficiency and recycling efficiency and reduces the labor cost.

[0026] In one embodiment, the strong magnetic component includes an electromagnet and a control circuit, and the control circuit is used to switch the adsorption and release states of the electromagnet. When it is necessary to adsorb the scrap steel bars, the control circuit can turn on the adsorption state of the electromagnet to adsorb the scrap steel bars; when it is necessary to release the scrap steel bars, the control circuit can switch to the release state of the electromagnet to close the adsorption to release the scrap steel bars. Furthermore, the control circuit is controlled by a programmable logic controller, and the gun head body 1 is provided with a sensor, and the sensor communicates with the programmable logic controller. Through sensor detection and feedback, the control circuit automatically enables or disables the magnetic attraction function. The sensor can be a force sensor, which automatically determines that the scrap steel bars adsorbed by the gun head body 1 have reached the maximum target value, and reminds the operator that it can be released, and automatically releases when the operator moves the gun head body 1 to the target position, further improving work efficiency.

[0029] In one embodiment, the cannon head body 1 is provided with a steel bar collection groove 11, which is V-shaped and has a plurality of guide grooves (not shown in the figure) for guiding the orderly accumulation of steel bars. The orderly collection of scrap steel bars can be improved, the volume of steel bars near the larger opening of the V-shaped shape is larger, and the volume of scrap steel bars near the smaller opening of the V-shaped shape is smaller, which further improves the sorting efficiency of scrap steel bars.

[0030] In one embodiment, the blast head body 1 is in the shape of a round cake with a diameter of 70 cm and a thickness of 20 cm. The blast head body 1 of this size is the optimal parameter size obtained by the inventor through multiple experiments and studies. On the one hand, it can ensure that the weight of the blast head body 1 is reasonable. On the other hand, it can also ensure the best force-bearing area, facilitate the disassembly and separation of buildings, and at the same time, crush the waste steel bars of various shapes into a ball.
