Description

Technical Field

[0001] This utility model relates to the field of emulsion explosive loading technology, and in particular to a vehicle-mounted automatic emulsion explosive extruder and loading vehicle. Background Technology

[0002] In the field of emulsion explosive production and application, vehicle-mounted emulsion explosive trucks have become key equipment for blasting operations in scenarios such as mining, highway and railway infrastructure, and water conservancy projects, thanks to their core advantages of "mobile operation and immediate material supply". Before loading emulsion explosives, the material extrusion directly determines the explosive supply efficiency, raw material utilization rate and on-site operation safety, which has an important impact on the overall project construction progress and operating costs.

[0003] Currently, the emulsion explosives truck industry mainly uses manual assisted extrusion and semi-automatic extruders. Manual extrusion mainly involves manually pushing and pulling the emulsion explosive rolls through double clamps or double clamps. Semi-automatic extrusion mainly changes the manual pushing and pulling extrusion method to hydraulic drive, reducing the intensity of manual labor. However, the method of breaking the emulsion explosive roll bags is still manual. At the same time, the manual or semi-automatic process is still relatively complex and the overall efficiency is not high. The extrusion effect is not ideal. The loading can only start after each batch of extrusion is completed, and there is a significant pause in the process connection, which cannot meet the needs of continuous loading in large-scale blasting operations.

[0004] Therefore, it is necessary to propose an automatic emulsion explosive extruder and a loading vehicle to solve or at least alleviate the above-mentioned defects. Utility Model Content

[0034] Please see the appendix Figure 1 ~Appendix Figure 8 This utility model provides an embodiment of an automatic extruder for vehicle-mounted emulsion explosives, comprising an extrusion mechanism 10, a lower extruder 20, and a cutting assembly 30. First, it should be noted that in this application, "lateral" refers to the width direction of the overall device, and "longitudinal" refers to the length direction of the overall device. Please refer to the accompanying drawings for details; the specific design is as follows:

[0035] The extrusion mechanism 10 includes a base frame 110, a vertical telescopic component 120, and an upper extruder 130. The vertical telescopic component 120 is connected between the base frame 110 and the upper extruder 130. The driving end of the vertical telescopic component 120 is connected to the upper extruder 130 and is arranged to extend and retract vertically. The lower extruder 20 is laterally connected to the base frame 110. The top of the lower extruder 20 is recessed downward to form an extrusion groove 210 for placing the emulsion explosive roll 40. The bottom end of the upper extruder 130 is protruding downward to form an extrusion part 131 corresponding to the extrusion groove 210. The cutting component 30 is connected to the bottom surface of the upper extruder 130 for cutting open the emulsion explosive roll 40. The base frame 110 has a discharge groove 111 for communicating with the emulsion explosive hopper 50. The lower extruder 20 has a slot 220 for communicating with the discharge groove 111.

[0036] Specifically, the vehicle-mounted automatic emulsion explosive extruder in this application includes an extrusion mechanism 10, a lower extruder 20, and a cutting assembly 30. The extrusion mechanism 10 is used to extrude material from the emulsion explosive roll 40 and needs to cooperate with the lower extruder 20, which is used to load the emulsion explosive roll 40. The extrusion mechanism 10 includes a base frame 110, a vertical telescopic assembly 120, and an upper extruder 130. The base frame 110 serves as an installation platform and can be installed on the explosive loading vehicle 60, while also providing a connection point for other components. The lower extruder 20 is laterally connected to the base frame 110. This facilitates the loading and unloading of the emulsion explosive roll 40. When loading the emulsion explosive roll 40, the lower extruder 20 is pulled out. After loading, when ready to cut and extrude the material, it is pushed to the underside of the upper extruder 130. The upper extruder 130 is used to achieve the extrusion effect by pressing down on the emulsion explosive roll 40 (after cutting) in the lower extruder 20. The upward and downward pressing is accomplished by the vertical telescopic component 120. Therefore, the vertical telescopic component 120 is connected between the base frame 110 and the upper extruder 130. The vertical telescopic component 120 drives the upper extruder 130 to move up and down by vertical telescopic extension of the drive end of the vertical telescopic component 120.

[0037] In detail, extrusion is performed by the interaction of the extrusion groove 210 and the extrusion section 131. The extrusion groove 210 is formed in the lower extruder 20, which is used to place the emulsion explosive roll 40 and cooperate with the extrusion section 131 to extrude material. The extrusion section 131 is formed at the bottom of the upper extruder 130. The upper extruder 130 presses down to drive the extrusion section 131 to move downward and apply downward pressure, thereby extruding the material in the emulsion explosive roll 40. Since the emulsion explosive roll 40 is usually sealed and packaged, the cutting component 30 is provided to cut the emulsion explosive roll 40. It is also installed on the bottom side of the upper extruder 130. Preferably, the cutting component 30 can be provided at both ends in the longitudinal direction to cut from both ends at the same time, thereby improving the extrusion efficiency. When the upper extruder 130 presses down, the cutting end of the cutting component 30 will cut open the emulsion explosive roll 40. At the same time, the extrusion is completed under the mutual extrusion action of the extrusion section 131 and the extrusion groove 210.

[0038] Furthermore, the base frame 110 is provided with a discharge trough 111, which is used to communicate with the emulsion explosive hopper 50 to guide the extruded emulsion explosive into the hopper 50 of the emulsion explosive cart. The lower extruder 20 is provided with a slot 220 to communicate with the discharge trough 111. Thus, when the lower extruder 20 moves directly below the upper extruder 130, the extruded emulsion explosive will flow into the discharge trough 111 through the slot 220 and finally reach the hopper 50.

[0039] In a preferred embodiment of the present invention, the vertical telescopic assembly 120 includes two vertical telescopic units (not shown in the figure), and one vertical telescopic unit is respectively provided at each end of the base frame 110; wherein, each vertical telescopic unit includes a guide cylinder 121, the bottom end of the guide cylinder 121 is fixed on the base frame 110, and the top end of the guide cylinder 121 is connected to the upper extruder 130 and is arranged to telescopically along the vertical direction.

[0040] It should be noted that vertical telescopic units are set at both ends simultaneously to ensure the synchronicity and uniformity of the telescopic movement, and to ensure the stability of the overall structure. Each vertical telescopic unit includes a guide cylinder 121, which uses the driving force of the cylinder to achieve vertical telescopic movement. It is easy to operate and has a stable thrust, which can meet the requirement of thorough material extrusion.

[0041] In a preferred embodiment of the present invention, each of the vertical telescopic units further includes a guide rod 122 extending vertically. The guide rod 122 is fixed on the base frame 110. The end of the upper extruder 130 is provided with a through hole 132, and the top end of the guide rod 122 passes through the through hole 132.

[0042] It should be noted that the guide rod 122 is used to limit the movement direction of the upper extruder 130 to prevent it from being accidentally deviated from its track by external force during vertical movement, which would prevent the extrusion part 131 and the extrusion groove 210 from correspondingly extruding and ultimately affecting the extrusion effect. Therefore, the guide rod 122 is used to limit the movement of the upper extruder 130 by vertical extension and contraction, and the upper extruder 130 slides along the guide rod 122 through the through hole 132.

[0043] In a preferred embodiment of the present invention, the extrusion groove 210 is a plurality of V-shaped grooves arranged side by side in the transverse direction, and the extrusion part 131 is a plurality of V-shaped protrusions arranged one-to-one with the V-shaped grooves.

[0044] It is worth noting that this multi-groove pressure distribution, combined with the V-shaped concave-convex structure, provides better positioning, concentrates the extrusion pressure towards the center, reduces residue in the bag, and improves utilization. Furthermore, the V-shape can be set to a V-shaped structure with a certain degree of curvature, which is suitable for cylindrical emulsion explosive rolls 40.

[0045] In another preferred embodiment of the present invention, the extrusion groove 210 is a rectangular groove, and the extrusion part 131 is a rectangular protrusion corresponding to the rectangular groove.

[0046] It is worth noting that in actual operation, some emulsion explosive rolls 40 may be slightly deformed due to transportation bumps and storage compression. Therefore, the rectangular groove is used to form a non-separate packaging form, which does not have high requirements for the shape of the emulsion explosive rolls 40, and avoids extrusion failure due to shape deviation. When using rectangular grooves, multiple emulsion explosive rolls 40 are placed side by side. Therefore, the specific form of the extrusion concave-convex structure can be set and processed by those skilled in the art as needed.

[0047] Furthermore, the slot 220 includes a side slot 221, the discharge slot 111 includes a first discharge slot 1111, the side slot 221 is disposed at one end of the lower extruder 20, and the first discharge slot 1111 is disposed on the side close to the side slot 221.

[0048] It should be noted that the lower extruder 20 described in this application adopts a drawer-type structure with a top opening. Therefore, in this preferred embodiment, when the slot 220 is set at one end, the lower extruder 20 can form the side slot 221 without a baffle at one end. When placed, the emulsion explosive roll 40 can have one end protruding from the side slot 221, which is convenient for extruding the emulsion explosive after being cut open. The first discharge trough 1111 is opened on the base frame 110 so that the emulsion explosive in the emulsion explosive roll 40 after being cut open at the end flows directly into the first discharge trough 1111 on the side of the side slot 221, and then flows into the emulsion explosive hopper 50 through the first discharge trough 1111 to collect. When loading explosives, it is then discharged through the emulsion explosive hopper 50. It can be understood that the first discharge trough 1111 is set on the side close to the side slot 221, which means the position relative to the lower extruder 20 when it is pushed onto the base frame 110.

[0049] Furthermore, the groove 220 also includes a bottom groove 222, and the discharge groove 111 also includes a second discharge groove 1112. The bottom groove 222 is located at the bottom of the lower extruder 20, and the second discharge groove 1112 is located below the bottom groove 222.

[0050] It should be understood that the bottom groove 222 facilitates the discharge capability of the lower extruder 20. Thus, when the lower extruder 20 moves directly below the upper extruder 130, the lower extruder 20 is also simultaneously positioned above the second discharge trough 1112 on the base frame 110. Therefore, during extrusion, in addition to flowing into the first discharge trough 1111 through the side groove 221, the other end can flow into the second discharge trough 1112 through the bottom groove 222, and the excess can continue to flow out through the side groove 221 to increase the discharge path and improve the discharge effect. It should be understood that the second discharge trough 1112 is located below the bottom groove 222, which means it is positioned relative to the lower extruder 20 when it is pushed onto the base frame 110.

[0051] Furthermore, the cutting assembly 30 includes a plurality of cutting blades 310 arranged side by side in a transverse direction, with the cutting ends of the cutting blades 310 facing downwards.

[0052] It should be noted that the number of cutting blades 310 can be set according to the number of emulsion explosive rolls 40 placed at one time. For example, in a preferred embodiment of this application, for V-shaped concave-convex structure or rectangular concave-convex structure, the number of emulsion explosive rolls 40 placed at one time is three. Therefore, the number of cutting blades 310 is also three. The position (cutting end) of the three cutting blades 310 can preferably be directly above each emulsion explosive roll 40 to ensure the cutting effect.

[0053] Furthermore, a sliding groove 113 is provided on the base frame 110, the sliding groove 113 is arranged in a transverse direction, and a pulley (not shown) is installed at the bottom of the lower extruder 20, the pulley being rotatably disposed in the sliding groove 113.

[0054] It should be noted that the slide groove 113 facilitates the sliding of the lower extruder 20, and in conjunction with the pulley, it also serves as a limiting and guiding function to ensure that the lower extruder 20 moves laterally without deflection.

[0055] In another preferred embodiment, the base frame 110 is also connected to the cutting assembly 30. The cutting assembly 30 located on the base frame 110 extends in a direction parallel to the movement trajectory of the lower extruder 20 and is located on the side near the side slot 221.

[0056] It is understandable that, in embodiments where the side slot 221 is located at one end, the emulsion explosive roll 40 typically extends out of the side slot 221 at one end. In this way, a cutting component 30 can also be provided on the base frame 110. When the lower extruder 20 enters the device laterally, the end of the emulsion explosive roll 40 that extends out is cut open by the cutting component 30 located on the base frame 110, allowing some material to flow out freely. The remaining internal material is then cut open by the upper cutting component 30 and further extruded, thereby improving the overall extrusion efficiency and the thoroughness of extrusion. Therefore, the extension direction of the cutting component 30 located on the base frame 110 is parallel to the movement trajectory of the lower extruder 20 to avoid blocking the movement trajectory of the lower extruder 20.

[0057] This utility model also provides a loading vehicle 60, including a vehicle body and a vehicle-mounted automatic emulsion explosive feeder as described above, wherein the vehicle-mounted automatic emulsion explosive feeder is connected to the bottom of the vehicle body. It is understood that this combination satisfies the core advantages of "mobile operation and immediate feeding".

[0058] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
