Description

Technical Field

[0001] The utility model relates to the technical field of explosive fillers, in particular to a manual filler for linear energy-gathering tube emulsion explosives. Background Art

[0002] Emulsion explosive is a kind of explosive containing emulsifier, usually made of explosive substances such as nitrate esters and nitroglycerin mixed with emulsifier, and is commonly used in military and civilian fields, including blasting, mining, construction, etc. During the blasting construction process, emulsion explosive needs to be filled into the drug tube. Since the blasting work environment is generally near the filling site, the infrastructure construction at the work site is relatively backward and the filled materials are flammable and explosive items with high danger, a manual emulsion explosive filling equipment is needed.

[0003] Existing explosive filling equipment usually mixes raw materials and then fills them into a cartridge to meet the needs of blasting. However, these filling equipment usually require energy to drive and cannot be used in a power outage, resulting in low flexibility in use. At the same time, the overall weight of the equipment is heavy and inconvenient to carry and use. In view of the above problems, the technicians in this field have proposed a manual filler for linear energy tube emulsion explosives to solve the above problems. Utility Model Content

[0004] In order to make up for the above shortcomings, the utility model provides a manual loader for linear energy-focused tube emulsion explosives, aiming to improve the problem in the prior art that the explosive loader requires electric drive and cannot be used in a power outage, resulting in certain limitations in usage scenarios.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a manual filler for linear energy-forming tube emulsion explosives, comprising a main frame, a storage tube threadedly connected to the left side of the main frame, an injection head threadedly connected to the other end of the storage tube, the main frame being slidably connected to a push piece via a limit groove arranged in the middle, an operating trigger movably connected to the bottom of the main frame via rivets, a push rod slidably connected to the inside of the main frame, and a rubber push head fixedly connected to one end of the push rod.

[0006] Furthermore, a push rod releasing the pressure plate is movably connected to the right side of the main frame, and a pressure plate spring is fixedly connected between the bottom end of the push rod releasing the pressure plate and the main frame.

[0007] Furthermore, a push piece spring is fixedly connected between the left side of the push piece and the main frame, and the push piece spring is sleeved on the outside of the push rod.

[0008] Furthermore, one end of the operating trigger is rotatably connected to the outside of the push piece.

[0009] Furthermore, the outer portion of the push rod is slidably connected to the inner portion of the push rod release pressing plate, and the outer portion of the push rod is slidably connected to the inner portion of the push plate.

[0010] Furthermore, the injection head is formed by connecting two sections of copper pipes through bucket-shaped brass plates by gas welding. The maximum diameter of the injection head is 35 mm, the inner diameter is 32 mm, and the overall height is 59 mm.

[0011] Furthermore, the material of the storage tube is brass, the maximum length of the storage tube is 500 mm, the maximum diameter is 53 mm, and the inner diameter is 53 mm.

[0012] Furthermore, the outside of the rubber push head is slidably connected to the inside of the material storage tube.

[0013] The utility model has the following beneficial effects:

[0014] 1. In the utility model, the push piece is moved by pulling the operating trigger, which in turn drives the push rod to move, thereby pushing the explosive material inside the storage tube to move through the rubber push head, thereby realizing the filling of emulsion explosives. It can work normally without power supply, which improves the flexibility of the filler. The mechanical structure design is simple and compact, which is convenient for on-site operation and maintenance.

[0015] 2. In the utility model, the filling of explosives can be completed through the mutual cooperation of the injection head, the storage tube, the main frame and other structures. At the same time, the overall structural parts are cut and processed from standard profiles, and the connection between the parts is made by gas welding, which reduces the production cost, improves the overall service life of the filling equipment, and reduces the failure rate.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Reference Figure 1 - Figure 3 The utility model provides an embodiment: a manual filler for linear energy-forming tube emulsion explosives, including a main frame 1, a storage tube 2 is threadedly connected to the left side of the main frame 1, and an injection head 7 is threadedly connected to the other end of the storage tube 2. The main frame 1 is slidably connected to a push piece 4 through a limit groove arranged in the middle, and an operating trigger 6 is movably connected to the bottom of the main frame 1 through a rivet. A push rod 8 is slidably connected inside the main frame 1, and one end of the push rod 8 is fixedly connected to a rubber push head 9. A push rod release pressure plate 3 is movably connected to the right side of the main frame 1, and a pressure plate spring 10 is fixedly connected between the bottom end of the push rod release pressure plate 3 and the main frame 1.

[0024] Specifically, the main components of the filler can be connected through the main frame 1, which is convenient for structural assembly, making the mechanical structure compact and convenient for operation and maintenance. Through the threaded connection between the storage tube 2 and the injection head 7, the explosive raw material can be injected into the storage tube 2, and connected to the main material tube through the injection head 7, so as to complete the filling of explosives. The operation is simple, and it is convenient to replace the injection head 7 with a larger or smaller caliber according to the usage to meet the filling requirements. The limit groove opened in the middle of the main frame 1 can limit the movement of the push piece 4, so that the push piece 4 can maintain horizontal movement when the operating trigger 6 is pulled, thereby realizing the stable operation of the structure. The movement of the push rod 8 can be limited by the main frame 1, so that the push rod 8 pushes the rubber push head 9 to move when moving, thereby pushing the raw material inside the storage tube 2 to fill the explosive. The push rod releases the compression plate 3 and the compression plate spring 10, so that the push rod 8 will not retreat after moving forward, thereby facilitating the filling of explosive raw materials.

[0025] Reference Figure 4 A push piece spring 5 is fixedly connected between the left side of the push piece 4 and the main frame 1. The push piece spring 5 is sleeved on the outside of the push rod 8, and one end of the operating trigger 6 is rotatably connected to the outside of the push piece 4.

[0026] Specifically, the push piece spring 5 can enable the operating trigger 6 to push the push piece 4 to slide along the push rod 8 to achieve reset after being released, thereby facilitating the operation of repeatedly pushing the explosive raw materials.

[0027] Reference Figure 3 The outside of the push rod 8 is slidably connected to the inside of the push rod release pressing sheet 3, the outside of the push rod 8 is slidably connected to the inside of the push sheet 4, and the outside of the rubber push head 9 is slidably connected to the inside of the material storage tube 2.

[0028] Specifically, by pulling the operating trigger 6, the push plate 4 is pushed forward obliquely under the action of the lever principle, thereby generating a bite force to drive the push rod 8 to move forward. The push rod releases the pressure plate 3 to compress the pressure plate spring 10, and after the operating trigger 6 is released, the pressure plate spring 10 can push the push rod to release the pressure plate 3 to restrict the push rod 8, thereby preventing the push rod 8 from retreating.

[0029] Reference Figure 2 The injection head 7 is formed by two sections of copper pipes connected by gas welding of bucket-shaped brass plates. The maximum diameter of the injection head 7 is 35mm, the inner diameter is 32mm, and the overall height is 59mm. The material of the storage tube 2 is brass. The maximum length of the storage tube 2 is 500mm, the maximum diameter is 53mm, and the inner diameter is 53mm.

[0030] Specifically, the replaceable injection head 7 is composed of two sections of copper tubes connected by gas welding of bucket-shaped brass plates and can be replaced, which improves the flexibility of use of the filler. The storage tube 2 is cut from standard copper tubes and milled with threads. Other components are cut and processed from standard profiles. The parts are connected by gas welding to meet the requirements of low cost, easy production and high strength.

[0031] Working principle: When charging, first, the on-site workers select the appropriate discharge head according to the construction needs, and prepare for the assembly of the emulsion explosive filling equipment. Then, they press the push rod with their thumb to release the pressure piece 3 and pull the push rod 8 to the end. Then, they hold the storage tube 2 with one hand and the main frame 1 with the other hand, and rotate the two hands in opposite directions to unscrew the storage and discharge mechanism as a whole. Then, they open the package of emulsion explosive and fill it into the storage tube 2 until the discharge port is about to discharge the material, and then rotate the storage and discharge mechanism back to the main frame 1 to complete the loading of the emulsion explosive. When the lever 8 is in motion, the push rod 8 is released, and the spring 10 pushes the push rod 8 forward, thereby releasing the pressure plate 3 and compressing the pressure plate spring 10, so that the push rod 8 can move forward through the pressure plate hole. When the lever 8 is in motion, the push rod 8 is released, and the spring 10 pushes the push rod 8 forward, thereby releasing the pressure plate 3 and compressing the pressure plate spring 10, so that the push rod 8 can move forward through the pressure plate hole. When the lever 8 is in motion, the push rod 8 is released, and the spring 10 pushes the push rod 8 forward, thereby releasing the pressure plate 3 and compressing the pressure plate spring 10, so that the push rod 8 can move forward through the pressure plate hole. When the lever 8 stops moving forward, the pressure plate hole is obliquely locked under the action of the pressure plate spring 10 to prevent the push rod 8 from moving backward. Repeating the above operation repeatedly makes the push rod 8 move forward but not backward under the control of the operating trigger 6, thereby pushing the raw material through the rubber push head 9 to complete the loading of the emulsion explosive. The loader can work normally without power supply, thereby improving the flexibility of use. The mechanical structure design is simple and compact, which is convenient for on-site operation and maintenance.

[0032] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
