Abstract
Description
Technical Field
[0001] This utility model relates to the field of protective mechanism technology, specifically a gun head protective mechanism for a gun machine. Background Technology
[0002] In many fields such as building construction, road construction, and mining, rock-breaking machines have become key equipment for crushing hard materials due to their powerful impact.
[0003] Based on the above, the inventors have discovered the following problems: the protective measures used by the blasting machine are extremely rudimentary, usually consisting of only a simple baffle for shielding. This basic protective measure has serious defects in practical applications. During road construction, when the blasting machine powerfully impacts the road surface, the enormous impact force causes broken stones to fly outwards at high speed. Due to the limited blocking capacity of the baffle, these flying stones can easily exceed the expected working range, posing a serious safety threat to construction workers, pedestrians, and buildings in the surrounding area.
[0004] Therefore, in view of this, we will study and improve the existing structure and its shortcomings, and provide a gun head protection mechanism to achieve a more practical purpose. Utility Model Content
[0005] The purpose of this utility model is to provide a gun head protection mechanism to solve the problems mentioned in the background art.
[0006] By adopting the above technical solution, the cannon head of the blasting machine is protected, thereby preventing flying stones from threatening the surrounding construction workers.
[0007] In view of the above problems, the technical solution proposed by this utility model is as follows:
[0008] A gun head protection mechanism includes a main body and an auxiliary mechanism. The main body includes a protective cylinder with a drawstring bag sewn to its upper end and a steel ring fitted to its bottom end. The protective cylinder includes a canvas base layer, a first cut-resistant layer, a sound-insulating layer, a second cut-resistant layer, a first oil-resistant layer, and a second oil-resistant layer. The auxiliary mechanism includes a counterweight bag with its upper end sewn to the bottom of the protective cylinder. Both ends of the counterweight bag have first through holes, and the counterweight bag has an iron chain inside. The two ends of the iron chain extend to the outside through a pair of first through holes.
[0009] Furthermore, a pair of second through holes are provided on one side of the pocket, and a tie rope is provided inside the pocket, with both ends of the tie rope extending to the outside through the pair of second through holes.
[0010] The beneficial effect of adopting the above-mentioned further solution is that the binding rope inside the bag extends to the outside through a pair of second through holes at both ends. This design makes it easy to tighten the bag opening by pulling the binding rope after the protective cylinder is put on the gun head. The tightened bag opening can fix the protective cylinder to the gun head.
[0011] Furthermore, a sound insulation layer is provided on the inner side of the canvas base layer, a second cut-resistant layer is provided on the inner side of the sound insulation layer, and a first oil-resistant layer is provided on the inner side of the second cut-resistant layer.
[0012] The beneficial effects of adopting the above-mentioned further solutions are that the sound insulation layer installed on the inner side of the canvas base layer can effectively block the noise generated during the operation of the blasting machine from propagating outward. Under the powerful impact of the blasting machine, high-decibel noise will be generated. The sound insulation layer can reduce noise energy through absorption and reflection, thereby reducing the noise intensity of the construction site and the surrounding environment. The second cut-resistant layer is located inside the sound insulation layer. When the blasting machine causes hard objects such as stones to fly and hit the protective cylinder, the second cut-resistant layer can further enhance the protective capability. The first oil-resistant layer is located inside the second cut-resistant layer, which can effectively prevent oil generated during the operation of the blasting machine from penetrating the protective cylinder and contaminating the internal blasting machine components or spreading to the surrounding environment.
[0013] Furthermore, a first cut-resistant layer is provided on the outer side of the canvas base layer, and a second oil-resistant layer is provided on the outer side of the first cut-resistant layer.
[0014] The beneficial effect of adopting the above-mentioned further solution is that, by setting a first cut-resistant layer on the outside of the canvas base layer, the entire protective cylinder can provide a primary barrier against impacts and cuts from external hard objects. The second oil-resistant layer is located outside the first cut-resistant layer, and its position makes it the first line of defense against external oil contaminants. Furthermore, the sound insulation layer is made of sound-absorbing cotton, and the thickness of the sound insulation layer is 3-8 mm.
[0015] The beneficial effect of adopting the above-mentioned further solution is that the sound insulation layer is made of sound insulation cotton. The sound insulation cotton has a porous and loose structure, which can effectively absorb and reflect the noise generated during the operation of the gun machine. When the noise sound wave enters the sound insulation cotton, the interconnected pores inside can make the sound wave continuously reflect, refract and rub against the fibers, converting the sound energy into heat energy and other forms of energy for consumption, thereby significantly reducing the intensity of the noise propagating outward.
[0016] Furthermore, the first and second cut-resistant layers are made of Kevlar fiber, and the thickness of the first and second cut-resistant layers is 0.5 to 2 mm.
[0017] The beneficial effect of adopting the above-mentioned further solution is that both the first and second anti-cut layers are made of Kevlar fiber. Kevlar fiber has the characteristics of high strength and high modulus. Its strength is several times higher than that of steel of the same weight. With its excellent mechanical properties, it can effectively resist the cutting and piercing of sharp and hard objects such as stones splashed out during the operation of the gun machine.
[0018] Furthermore, the first and second anti-oil layers are fluorocarbon polymer coatings, and the thickness of the first and second anti-oil layers is 0.05 to 0.2 mm.
[0019] The beneficial effect of adopting the above-mentioned further solution is that the first and second anti-oil layers are coated with fluorocarbon polymers, which have extremely low surface energy, making it difficult for oil to adhere to their surfaces.
[0020] Furthermore, the binding rope is made of nylon.
[0021] The advantage of adopting the above-mentioned further solution is that the nylon material has high strength, which allows the binding rope to withstand a certain amount of tension.
[0022] Furthermore, an observation window is provided on the bottom side of the protective cylinder, and a polycarbonate film is provided inside the observation window. The beneficial effect of adopting the above-mentioned further solution is that by providing an observation window, it is convenient to observe the position of the gun head when installing the protective cylinder, and by providing a polycarbonate film inside the observation window, the observation window can be shielded.
[0023] The beneficial effects of this utility model are as follows: The gun head protection mechanism obtained by the above design includes a first and second cut-resistant layer in the protective cylinder. This multi-layered cut-resistant structure effectively resists the impact and cutting of hard objects such as stones during gun operation, preventing them from easily tearing the protective cylinder and avoiding stones flying out of the protection range and causing injury to surrounding personnel, equipment, and buildings, thus greatly improving the safety of the construction site. The internal sound insulation layer can block and absorb the noise generated by the gun operation, reducing the transmission of noise to the surrounding environment, reducing damage to the hearing of construction workers and interference with the lives and work of surrounding residents, making the construction more environmentally friendly. The presence of the first and second oil-resistant layers allows the protective cylinder to effectively block oil stains that may be generated during gun operation, preventing oil stains from contaminating the surrounding environment and maintaining the cleanliness of the construction site and its surroundings. This design also facilitates the cleaning and maintenance of the protective cylinder itself, extending its service life. The drawstring bag sewn at the top of the protective cylinder allows users to easily secure it after placing it on the gun head. The steel ring fitted at the bottom of the protective cylinder enhances its structural strength, enabling it to maintain its overall shape better and resist deformation during gun operation, especially when subjected to external forces such as stone impacts, ensuring the continuous and effective performance of its protective function. The counterweight bag is sewn to the bottom of the protective cylinder, with an iron chain inside. The two ends of the iron chain extend to the outside through the first through hole. The weight of the iron chain increases the downward pressure on the entire protective cylinder, allowing it to maintain more stable contact with the ground during gun operation. This prevents the protective cylinder from shifting due to gun vibration and impact, thus maintaining a good protective state at all times. It also serves as a dustproof barrier, using the protective cylinder to isolate dust generated during gun operation. Attached Figure Description

Detailed Implementation
[0031] 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.
[0032] Please see Figure 1 - Figure 6This utility model provides a technical solution: a gun head protection mechanism, including a main body 100 and an auxiliary mechanism 200. The main body 100 includes a protective cylinder 1001, with a drawstring bag 1003 sewn to the upper end of the protective cylinder 1001, and a steel ring 1002 fitted to the bottom end of the protective cylinder 1001. The protective cylinder 1001 includes a canvas base layer 100101, a first cut-resistant layer 100102, a sound insulation layer 100103, a second cut-resistant layer 100104, a first oil-resistant layer 100105, and a second oil-resistant layer 100106. The auxiliary mechanism 200 includes a counterweight bag 2001, with the upper end of the counterweight bag 2001 sewn to the bottom of the protective cylinder 1001. Both ends of the 2001 have first through holes 2002. Inside the counterweight bag 2001 is an iron chain 2003, with both ends of the chain 2003 extending outwards through a pair of first through holes 2002. The protective cylinder 1001 includes a first cut-resistant layer 100102 and a second cut-resistant layer 100104. This multi-layered cut-resistant structure effectively resists the impact and cutting of hard objects such as stones during the operation of the blasting machine, preventing them from easily tearing the protective cylinder 1001 and avoiding stones flying out of the protective area and causing injury to surrounding personnel, equipment, and buildings, greatly improving the safety of the construction site. The internal sound insulation layer 100103 can block and absorb the noise generated by the blasting machine operation, reducing noise pollution. The protective sleeve 1001 effectively blocks oil stains that may be generated during the operation of the blasting machine, preventing oil from contaminating the surrounding environment and keeping the construction site and surrounding area clean. The presence of the first oil-proof layer 100105 and the second oil-proof layer 100106 also helps to clean and maintain the protective sleeve 1001 itself, extending its service life. The drawstring bag 1003 sewn onto the upper end of the protective sleeve 1001 allows users to easily attach the protective sleeve 1001 to the blasting head and secure it. The steel ring 10 at the bottom of the protective sleeve 1001 further enhances its environmental friendliness. 02 enhances the structural strength of the bottom of the protective cylinder 1001, enabling it to better maintain its overall shape and resist deformation during the operation of the artillery, especially when subjected to external forces such as stone impacts, thus ensuring the continuous and effective performance of its protective function. The counterweight bag 2001 is sewn to the bottom of the protective cylinder 1001, and an iron chain 2003 is installed inside it. The two ends of the iron chain 2003 extend to the outside through the first through hole 2002. The weight of the iron chain 2003 increases the downward pressure of the entire protective cylinder 1001, allowing it to maintain more stable contact with the ground during artillery operation. This prevents the protective cylinder 1001 from shifting due to vibration and impact from the artillery, thereby maintaining a good protective state at all times. The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0033] Please see Figure 1 - Figure 6 The drawstring bag 1003 has a pair of second through holes 1005 on one side. A binding rope 1004 is provided inside the drawstring bag 1003, with both ends of the rope 1004 extending outwards through the pair of second through holes 1005. This design facilitates tightening the bag opening by pulling the binding rope 1004 after the protective cylinder 1001 is fitted onto the gun head, thus securing the protective cylinder 1001 to the gun head. The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.
[0034] Please see Figure 1 - Figure 6The canvas base layer 100101 has a sound insulation layer 100103 on its inner side, a second cut-resistant layer 100104 on its inner side, and a first oil-resistant layer 100105 on its inner side. The canvas base layer 100101 has a first cut-resistant layer 100102 on its outer side, and a second oil-resistant layer 100106 on its outer side. The sound insulation layer 100103 is made of sound-absorbing cotton and has a thickness of 3-8 mm. The first and second cut-resistant layers 100102 and 100104 are made of Kevlar fiber. The thickness of the cut-resistant layer 100102 and the second cut-resistant layer 100104 is 0.5-2mm. The first oil-resistant layer 100105 and the second oil-resistant layer 100106 are fluorocarbon polymer coatings with a thickness of 0.05-0.2mm. The binding rope 1004 is made of nylon. An observation window 1006 is provided on the bottom side of the protective cylinder 1001. The observation window 1006 is provided with a polycarbonate film inside. A sound insulation layer 100103 is provided on the inner side of the canvas base layer 100101, which can effectively block the noise generated during the operation of the gun machine from spreading outward.The powerful impact of the blasting machine generates high-decibel noise. The sound insulation layer 100103 can reduce noise energy through absorption and reflection, thereby lowering the noise intensity at the construction site and surrounding environment. The second cut-resistant layer 100104 is located inside the sound insulation layer 100103. When the blasting machine causes rocks or other hard objects to fly and impact the protective cylinder 1001, the second cut-resistant layer 100104 can further enhance the protective capability. The first oil-resistant layer 100105 is located inside the second cut-resistant layer 100104, which can effectively prevent oil generated during the operation of the blasting machine from penetrating the protective cylinder. If the barrel 1001 becomes contaminated with internal gun components or spreads to the surrounding environment, a first cut-resistant layer 100102 is installed on the outside of the canvas base layer 100101. This provides the entire protective barrel 1001 with the primary barrier against impacts and cuts from external hard objects. The second oil-resistant layer 100106 is located outside the first cut-resistant layer 100102, and its position makes it the first line of defense against external oil contamination for the protective barrel 1001. The sound-insulating layer 100103 is made of sound-absorbing cotton, which has a porous and loose structure that can effectively absorb and reflect gun components. Noise generated during operation is absorbed into the sound insulation cotton through its interconnected pores. The sound waves are continuously reflected, refracted, and rubbed against the fibers, converting sound energy into heat and other forms of energy, thus significantly reducing the intensity of noise propagation. Both the first cut-resistant layer 100102 and the second cut-resistant layer 100104 are made of Kevlar fiber. Kevlar fiber has high strength and high modulus, its strength being several times higher than that of steel of the same weight. Its excellent mechanical properties effectively resist the splashes of air during gun operation. For cutting and piercing by sharp and hard objects such as stones, the first oil-proof layer 100105 and the second oil-proof layer 100106 are coated with fluorocarbon polymer. Fluorocarbon polymer has extremely low surface energy, which makes it difficult for oil to adhere to its surface. Nylon material has high strength, which allows the binding rope 1004 to withstand a certain amount of tension. By opening an observation window 1006, it is easy to observe the position of the gun head when the protective cylinder 1001 is installed. By setting a polycarbonate film inside the observation window 1006, the observation window 1006 can be covered.Specifically, the working principle of this type of gun head protection mechanism is as follows: In use, the protective cylinder 1001 is fitted onto the gun head, and the binding rope 1004 is tightened to secure the bag 1003. The binding rope 1004 fixes the protective cylinder 1001 to the gun head. The counterweight bag 2001 is sewn to the bottom of the protective cylinder 1001 at its upper end. The two ends of the internal iron chain 2003 extend to the outside through the first through hole 2002. The iron chain 2003 has a certain weight. When the protective cylinder 1001 is installed... When the gun barrel fires, the weight of the chain 2003 causes the counterweight bag 2001 to sag, increasing the downward pressure on the entire protective cylinder 1001. This downward pressure effectively prevents the protective cylinder 1001 from shifting due to external forces when the gun barrel vibrates or experiences impacts. The noise generated by the gun barrel operation propagates outward in the form of sound waves. When the sound waves reach the protective cylinder 1001, the sound insulation layer 100103 located inside the canvas base layer 100101 begins to function. The porous and loose structure of the sound insulation cotton prevents the sound waves from being dislodged. The sound energy is continuously reflected, refracted, and rubbed against the fibers, converting sound energy into heat and other forms of energy for consumption. This effectively reduces the intensity of noise propagation and minimizes noise interference to the surrounding environment and construction personnel. By setting a second cut-resistant layer 100104 and a first cut-resistant layer 100102 on the inside and outside of the canvas base layer 100101 respectively, it can prevent stones or other sharp objects from penetrating the protective cylinder 1001 during construction, thus avoiding danger to surrounding personnel. By setting a first oil-resistant layer 100105 and a second oil-resistant layer 100106, it can prevent oil stains on the blasting head and external oil stains during construction from soiling the protective cylinder 1001. The steel ring 1002 fitted at the bottom of the protective cylinder 1001 can enhance the structural strength of the bottom of the protective cylinder 1001, so that it can better maintain its overall shape and is not easily deformed during blasting operations, especially when subjected to the impact of stones, ensuring the continuous and effective performance of the protective function.
