Description

Technical Field

[0001] This invention relates to the field of emulsion explosives loading technology, and in particular to a double-belt extrusion loading vehicle for emulsion explosives. Background Technology

[0002] The explosive loading vehicle is mainly used for explosive loading operations in drilling and blasting construction scenarios such as tunnels and mines. It is the core equipment for realizing mechanized and unmanned production in mining and tunnel construction. It uses an extrusion device to peel open the finished emulsion explosive cartridges and extrude the explosives, which are then transported to deep holes and excavation holes through a hopper, a loading device and a boom to complete the explosive filling. It is gradually replacing the traditional manual explosive loading method.

[0003] Currently, most emulsion explosive loading vehicles in the industry use manual or semi-automatic extrusion mechanisms for the extrusion process, and the bag-breaking process of emulsion explosive rolls relies entirely on manual operation. This extrusion method is not only complex and requires a lot of manual intervention, but also suffers from long extrusion times and incomplete extrusion, resulting in a lack of significant efficiency advantage of loading vehicles compared to manual loading, which severely limits the widespread application of emulsion explosive loading vehicles. Furthermore, for loading vehicles with two-seat cabs, there is no space on the side of the cab, requiring the extrusion mechanism to be located below the hopper. However, existing extrusion devices are too large in size and have too high a loading height. Traditional extrusion roller structures also have high installation space requirements and poor layout flexibility, making them unsuitable for the spatial layout needs of loading vehicles. They also struggle to meet the requirements of automated extrusion, waste separation, and compact layout, further restricting the operational efficiency and scenario adaptability of emulsion explosive loading vehicles.

[0004] Therefore, it is necessary to propose a double-belt extrusion loading vehicle for emulsion explosives to solve or at least alleviate the above-mentioned defects. Summary of the Invention

[0005] The main objective of this invention is to provide a double-belt extrusion loading vehicle for emulsion explosives, so as to solve the problems of poor automation effect and poor layout flexibility of the loading vehicle in the prior art.

The hopper is connected to the vehicle body, the lifting mechanism is connected to the hopper and is vertically retractable, and the vertical double-belt extrusion device is connected to the lifting mechanism. The vertical double belt extrusion device includes a frame and an upper belt assembly, a lower belt assembly, and a cutting assembly built into the frame. The top of the frame has a feed inlet and a waste outlet, and the bottom of the frame has a feeding hopper and a discharge outlet. The discharge outlet is connected to the silo through a feeding pipe. The lower belt assembly is horizontally positioned in the middle of the frame. Both sides of the lower belt assembly have discharge ports that communicate with the upper hopper. The end of the upper belt assembly near the feed port is inclined upward to form an opening with the lower belt assembly. The cutting component is positioned near the opening to cut the emulsion explosive roll. The end of the upper belt assembly near the waste port is horizontally positioned and a waste outlet gap is reserved between it and the lower belt assembly.

[0007] Preferably, the upper belt assembly includes an upper belt and two upper pulleys, which are rotatably connected to the inner ends of the upper belt, and the upper pulley near the feed inlet is higher than the upper pulley near the waste outlet, so as to form an inclined upper belt assembly.

[0008] Preferably, the lower belt assembly includes a lower belt, two lower belt pulleys, and a plurality of lower guide rollers arranged longitudinally at intervals. The two lower belt pulleys are respectively rotatably connected to the inner ends of the lower belt and arranged opposite each other longitudinally. The lower guide rollers are rotatably connected to the top inner side of the lower belt.

[0009] Preferably, the upper belt assembly further includes a plurality of upper guide rollers spaced apart along the inclined direction of the upper belt, the upper guide rollers being rotatably connected to the inner bottom of the upper belt.

[0010] Preferably, the position of each of the upper guide rollers is vertically movable, so that the opening between the upper belt assembly and the lower belt assembly is adjustable, and the cutting assembly is disposed in the opening.

[0011] Preferably, it further includes a guide roller, which is rotatably connected to the frame and is located between the upper belt assembly and the feed inlet and above the upper pulley at the high end.

[0012] Preferably, the cutting assembly employs a rotating blade, which is rotatably connected to the frame and positioned at the entrance of the opening.

[0013] Preferably, it further includes two discharge hoods arranged laterally opposite each other, the two discharge hoods being respectively disposed on both sides of the lower belt assembly, and the discharge hoods having a slope that slopes downward from the inside out in the lateral direction.

[0014] Preferably, it also includes a waste trough, which is connected to the outside of the frame and disposed at the waste inlet.

[0015] Preferably, the medicine loading vehicle further includes a maintenance mechanism, which includes a support frame and a maintenance platform. The support frame is connected to the vehicle body, and the maintenance platform is vertically movably connected to the support frame, and the maintenance platform itself is horizontally extendable.

[0016] Compared with the prior art, the present invention has the following beneficial effects: The present invention provides a double-belt extrusion loading cart for emulsion explosives, comprising a vertical double-belt extrusion device and a loading cart. The loading cart includes a cart body, a hopper, and a lifting mechanism. The hopper is connected to the cart body, and the lifting mechanism is connected to the hopper and is vertically retractable. The vertical double-belt extrusion device is connected to the lifting mechanism. The vertical double-belt extrusion device includes a frame and an upper belt assembly, a lower belt assembly, and a cutting assembly built into the frame. The top of the frame has a feed inlet and a waste outlet, and the bottom of the frame has a feeding hopper and a discharge outlet. The discharge outlet is connected to the hopper through a feeding pipe. The lower belt assembly is horizontally arranged in the middle of the frame. Both sides of the lower belt assembly have discharge outlets connected to the feeding hopper.

The cutting assembly is arranged near the opening to cut the emulsion explosive roll. The end of the upper belt assembly near the waste outlet is horizontally arranged and a waste outlet gap is reserved between it and the lower belt assembly. The lifting mechanism of this loading vehicle allows for vertical height adjustment of the extrusion device. During operation, the extrusion device can be raised to meet the needs of high-level feeding, and when not in operation, it can be lowered to match the height of the entire vehicle to meet the dimensional requirements for vehicle travel and relocation. The cutting component automatically cuts the explosive roll during the conveying process, and the continuous oblique extrusion of the double belts achieves automatic extrusion of the explosive, greatly reducing manual intervention, reducing the labor intensity of operators, and improving extrusion efficiency. Waste materials such as explosive residue and clips can be conveyed to the waste outlet through the waste outlet gap with the belt. The explosive falls into the feeding hopper through the discharge port and is then conveyed to the silo. The entire process is fully automated and compact, giving full play to the mechanized operation advantages of the loading vehicle. Attached Figure Description

[0025] Please see the appendix Figure 1-4 An embodiment of the present invention provides a double-belt extrusion loading cart 20 for emulsion explosives, comprising a vertical double-belt extrusion device 10 and a loading cart 20. First, it should be noted that in this application, "longitudinal" refers to the length direction along the frame 110, and "lateral" refers to the width direction along the frame 110. Please refer to the accompanying drawings for details; the specific design is as follows: The loading vehicle 20 includes a vehicle body 210, a hopper 220, and a lifting mechanism 230. The hopper 220 is connected to the vehicle body 210, and the lifting mechanism 230 is connected to the hopper 220 and is vertically retractable. The vertical double-belt extrusion device 10 is connected to the lifting mechanism 230. The vertical double-belt extrusion device 10 includes a frame 110 and an upper belt assembly 120, a lower belt assembly 130, and a cutting assembly 140 built into the frame 110. The top of the frame 110 has a feed inlet 111 and a waste outlet 112, and the bottom of the frame 110 has a hopper 113. The machine has a discharge port 114, which is connected to the hopper 220 via a feeding pipe; the lower belt assembly 130 is horizontally arranged in the middle of the frame 110, and the lower belt assembly 130 has discharge ports 134 on both sides that are connected to the feeding hopper 113; the upper belt assembly 120 is inclined upward at one end near the feed port 111 to form an opening with the lower belt assembly 130; the cutting component 140 is arranged near the opening to cut the emulsion explosive roll; the upper belt assembly 120 is horizontally arranged at one end near the waste port 112 and a waste outlet gap is reserved between it and the lower belt assembly 130.

[0026] Specifically, the emulsion explosive double-belt extrusion loading vehicle 20 in this application includes a vertical double-belt extrusion device 10 and a loading vehicle 20. The vertical double-belt extrusion device 10 is used for automated extrusion, and the extruded explosive is then transported to the loading vehicle 20 for loading. By connecting the vertical double-belt extrusion device 10 to the vertically extendable lifting mechanism 230 of the loading vehicle 20, the vertical height of the extrusion device can be flexibly adjusted. During operation, the extrusion device can be raised to meet the operational requirements of feeding material to the hopper 220 at a high position. When not in operation, the extrusion device can be lowered to the same height as the entire vehicle, adapting to the size requirements of the loading vehicle 20 for driving and relocation. This effectively solves the problem of no arrangement space on the side of the double-cab loading vehicle 20 and improves the arrangement flexibility of the extrusion device. Meanwhile, the vertical double-belt extrusion device 10 integrates upper and lower belt assemblies 130 and a cutting assembly 140 within its frame 110. Utilizing the opening formed by the inclined end of the upper belt assembly 120 and the lower belt assembly 130, the cutting assembly 140 at the opening enables automatic bag breaking of the emulsion explosive rolls, replacing traditional manual bag breaking operations and significantly reducing manual intervention. The discharge ports 134 on both sides of the lower belt assembly 130 cooperate with the bottom feeding hopper 113 to ensure that the explosives, after continuous extrusion by the double belts, are smoothly collected and transported to the silo 220 through the discharge port 114 and the feeding pipe, resulting in more thorough extrusion and smoother conveying. The waste outlet gap between the horizontal end of the upper belt assembly 120 and the lower belt assembly 130 enables automatic separation of waste materials such as explosive casings and clips from the explosives. The waste is conveyed by the belt to the waste outlet 112 for discharge, ensuring that the feeding, extrusion, discharge, and waste removal processes of the device proceed in an orderly manner. The overall structure enables automated extrusion and feeding operations, reduces the labor intensity of operators, improves the extrusion efficiency of the loading cart 20, and the double belt pressure structure is more compact than the traditional roller extrusion structure, optimizing the overall spatial layout of the loading cart 20.

[0027] It is worth mentioning that when conveying the emulsion explosive roll to the vertical double belt extrusion device 10, an automatic feeding device can be used, such as a lifting belt or a vertical lifting machine, to meet the requirements of an automated structure. This is a relatively mature technology, so it will not be described in detail here.

[0028] In a preferred embodiment of the present invention, the upper belt assembly 120 includes an upper belt 121 and two upper pulleys 122. The two upper pulleys 122 are rotatably connected to the two ends inside the upper belt 121, and the upper pulley 122 near the feed inlet 111 is higher than the upper pulley 122 near the waste outlet 112, so as to form the upper belt assembly 120 with an inclined arrangement.

[0029] It should be noted that the upper belt assembly 120 consists of an upper belt 121 and two upper pulleys 122. By setting the upper pulley 122 near the feed inlet 111 to be higher than the upper pulley 122 near the waste outlet 112, the inclined configuration of the upper belt assembly 120 is naturally formed without the need for additional inclined support structures. This significantly simplifies the overall structure of the upper belt assembly 120 and reduces the processing, installation, and maintenance costs of the assembly. The inclined upper belt 121 and the horizontal lower belt 131 form a gradual compression space, allowing the medicine roll to be gradually compressed during the conveying process, improving the thoroughness of extrusion and avoiding the problem of insufficient extrusion of the medicine roll due to sudden changes in extrusion pressure.

[0030] In a preferred embodiment of the present invention, the lower belt assembly 130 includes a lower belt 131, two lower belt pulleys 132 and a plurality of lower guide rollers 133 arranged longitudinally at intervals. The two lower belt pulleys 132 are respectively rotatably connected to the inner ends of the lower belt 131 and arranged opposite each other longitudinally. The lower guide rollers 133 are rotatably connected to the inner top of the lower belt 131.

[0031] It is important to note that multiple longitudinally spaced lower guide rollers 133 are added to the lower belt 131 and the two lower pulleys 132, and these lower guide rollers 133 are rotatably connected to the inner top of the lower belt 131. The longitudinally opposite arrangement of the two lower pulleys 132 ensures that the lower belt 131 remains horizontal, providing a stable foundation for the extrusion operation. The lower guide rollers 133 on the inner top provide uniform and effective support to the lower belt 131, preventing it from sinking or deforming due to excessive force when extruding the emulsion explosive. This ensures the stability of the lower belt 131's horizontal shape, resulting in uniform pressure distribution during double-belt extrusion and further improving the thoroughness of the extrusion. Simultaneously, the rotatable connection between the spaced lower guide rollers 133 and the lower belt 131 significantly reduces frictional resistance, ensuring smooth transmission of the lower belt 131, reducing belt wear, extending the service life of the lower belt 131, and adapting to the continuous, high-intensity extrusion requirements of the charging vehicle 20.

[0032] It is worth mentioning that the lower belt 131 is not limited to the synchronous pulley, but may also include a roller chain mesh (not shown in the figure). The belt can not only transport the explosive cartridges and complete the extrusion, but the emulsion explosive can also fall directly from the roller chain mesh into the hopper below. The chain mesh also has a filtering operation to filter out the explosive casing, clips and other impurities.

[0033] In a preferred embodiment of the present invention, the upper belt assembly 120 further includes a plurality of upper guide rollers 123 spaced apart along the inclined direction of the upper belt 121, the upper guide rollers 123 being rotatably connected to the inner bottom of the upper belt 121.

[0034] It is worth noting that the inclined upper belt 121 is prone to bulging and deformation due to the extrusion force during the extrusion operation, which leads to uneven extrusion gap between the two belts and affects the extrusion effect. The upper guide roller 123 can provide stable support for the bottom of the inclined upper belt 121, effectively preventing the deformation of the upper belt 121, ensuring that the extrusion gap between the two belts is uniform, and allowing the emulsion explosive roll to be continuously and evenly extruded during the conveying process, ensuring that the extrusion is sufficient and thorough.

[0035] In a preferred embodiment of the present invention, the position of each of the upper guide rollers 123 is vertically movable so that the opening between the upper belt assembly 120 and the lower belt assembly 130 is adjustable, and the cutting assembly 140 is disposed in the opening.

[0036] It is worth noting that the vertically movable design of the upper guide roller 123 allows for flexible adjustment of the sag of the upper belt 121, thereby enabling free adjustment of the opening between the upper belt assembly 120 and the lower belt assembly 130. This adapts to different specifications of emulsion explosive rolls with diameters ranging from 30mm to 130mm, meeting the extrusion needs of different construction operations without requiring replacement of the extrusion assembly. This significantly improves the versatility of the device and reduces the cost of use and replacement. Specifically, a vertical elongated hole can be provided to facilitate the installation and adjustment of the vertical position of the upper guide roller 123. Simultaneously, the cutting assembly 140 is positioned within the opening, ensuring that the emulsion explosive roll is precisely cut as soon as it enters the extrusion area. This more accurate bag-breaking position ensures that the explosive flows out fully during the subsequent dual-belt extrusion process, improving extrusion efficiency. The adjustable opening, combined with the cutting assembly 140, allows for the effective and thorough breaking of explosive rolls of different diameters, avoiding the problems of incomplete breaking of small-diameter rolls and over-cutting of large-diameter rolls, further enhancing the reliability of automatic bag breaking.

[0037] As another preferred embodiment of the present invention, it further includes a guide roller 150, which is rotatably connected to the frame 110. The guide roller 150 is located between the upper belt assembly 120 and the feed inlet 111 and is positioned above the upper pulley 122 at the high end.

[0038] It should be noted that in this embodiment, the inclined upper belt assembly 120 does not need to extend to the feed inlet 111. The emulsion explosive rolls fed from the feed inlet 111 can be effectively guided and conveyed by the guide roller 150. The rotating connection reduces frictional resistance between the rolls and the feed inlet, preventing damage at the feed inlet 111. Simultaneously, the rolls are guided individually and orderly into the inclined upper belt assembly 120, effectively preventing blockages and accumulation at the feed inlet 111 when too much explosive is added, ensuring continuous and smooth feeding. Please refer to the appendix for details. Figure 4Preferably, the guide roller 150 is not limited to a rotating roller, and the roller surface is not limited to a smooth metal surface. It can be a serrated roller, a roller with concave and convex surfaces, or other non-metallic rollers to adapt to emulsion explosive rolls of different specifications and sizes, thereby improving the versatility of the equipment.

[0039] Furthermore, the cutting assembly 140 employs a rotating blade 141, which is rotatably connected to the frame 110 and positioned at the entrance of the opening.

[0040] It should be understood that the rotating blade 141's rotating bag-breaking method is more efficient, and can quickly and continuously cut through the emulsion explosive rolls entering the opening. It is suitable for the continuous feeding requirements of the explosive rolls and greatly improves the operating efficiency of the entire extrusion device. Especially in the embodiment with the guide roller 150, the rotating blade 141 is set at the opening entrance, so that the explosive roll is broken as soon as it enters the extrusion area after being guided by the guide roller 150. This allows the explosive to flow out fully and quickly during the subsequent continuous extrusion process of the double belt, ensuring the thoroughness of the extrusion.

[0041] Furthermore, it also includes two discharge hoods 160 arranged laterally opposite each other. The two discharge hoods 160 are respectively arranged on both sides of the lower belt assembly 130, and the discharge hoods 160 have a slope that slopes downward from the inside to the outside in the lateral direction.

[0042] It should be noted that the discharge hood 160 can effectively guide and collect the emulsion explosive flowing from the discharge ports 134 on both sides of the lower belt assembly 130, preventing the explosive from scattering into other parts inside the frame 110 during the discharge process. This ensures that all the explosive flows into the bottom feed hopper 113, reducing waste and improving collection efficiency. Simultaneously, the inclined slope of the discharge hood 160 allows gravity to guide the explosive to slide quickly into the feed hopper 113, preventing accumulation at the discharge ports 134 and ensuring the continuity of the extrusion and discharge operations.

[0043] Furthermore, it also includes a waste trough 170, which is connected to the outside of the frame 110 and is located at the waste inlet 112.

[0044] It is important to note that the waste trough 170 can centrally collect waste materials such as spent explosive casings and clips discharged from the waste outlet 112, achieving orderly separation and centralized collection of waste materials from emulsion explosives. This prevents waste materials from scattering onto other parts of the loading vehicle 20 or the construction site, maintaining a clean working environment and improving the standardization of construction operations. Simultaneously, the waste trough 170 is connected to the outside of the frame 110, featuring a simple structural design. Operators can complete the waste cleaning work without disassembling the extrusion device, making operation simple and convenient, significantly improving the ease of operation of the equipment. Furthermore, the centralized waste collection method facilitates unified waste treatment, meeting the environmental protection and management requirements of the construction site.

[0045] Furthermore, the medicine loading vehicle 20 also includes a maintenance mechanism 240, which includes a support frame 241 and a maintenance platform 242. The support frame 241 is connected to the vehicle body 210, and the maintenance platform 242 is vertically movably connected to the support frame 241, and the maintenance platform 242 itself is horizontally extendable.

[0046] Understandably, the vertically movable design allows the maintenance platform 242 to flexibly adjust its height, adapting to maintenance and cleaning areas at different heights, such as the vertical double-belt extrusion device 10 and the feed inlet of the hopper 220. The laterally extendable design of the maintenance platform 242 allows it to extend into the maintenance area during operation and retract to the side of the vehicle body 210 when not in operation, without occupying the driving and construction space of the charging vehicle 20. This fully utilizes the overall space of the charging vehicle 20 and ensures the compactness of the overall vehicle layout. Simultaneously, the maintenance mechanism 240 assists operators in safely and conveniently completing the cleaning, inspection, and maintenance of the extruder and the feed inlet of the hopper 220 without the need for additional climbing equipment, reducing safety risks during maintenance operations and improving the convenience of equipment maintenance. Timely and convenient maintenance and cleaning effectively ensure the working performance of the equipment, extend the service life of the charging vehicle 20 and the extrusion device, and further improve the operational reliability of the charging vehicle 20.

[0047] The above are merely preferred embodiments of the present invention and do not limit the scope of the patent. Any equivalent structural or procedural transformations made based on the description and drawings of the present invention, or direct or indirect applications in other related technical fields, are similarly included within the scope of patent protection of the present invention.
