Detailed Embodiments

[0028] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0029] Embodiment 1:

[0030] Please refer to Figures 1-5, a shotcrete device with wire mesh for mortar bolts, comprising a main body 1, a storage mechanism and a spraying mechanism. The storage mechanism includes a feed inlet 2, a cover plate 3, a connecting plate 4, a buckle 5, a spring 6 and an anti-caking mechanism. The feed inlet 2 is fixedly connected to the main body 1. The cover plate 3 is slidably connected to the feed inlet 2. The connecting plate 4 is rotatably connected to the cover plate 3. The buckle 5 is installed on the connecting plate 4 and is detachably connected to the feed inlet 2. The spring 6 is installed inside the connecting plate 4, and one end thereof is fixedly connected to the buckle 5. The anti-caking mechanism includes a stirring motor 7, a tank cover 8, a stirring shaft 9 and a fixing rod 10. The stirring motor 7 is fixedly installed on the tank cover 8. The tank cover 8 is fixedly connected to the main body 1. One end of the connecting shaft is fixedly connected to the output end of the stirring motor 7. The fixing rod 10 is fixedly installed on the stirring shaft 9.

[0031] In this embodiment, the storage mechanism includes a feed inlet 2, a cover plate 3, a connecting plate 4, a buckle 5, a spring 6 and an anti-caking mechanism. During use, at this time, the cover plate 3 is pulled. The slider 21 on the cover plate 3 and the connecting plate 4 slides in the sliding groove of the feed inlet 2, and the block 22 also slides in the sliding groove at the same time. When the connecting plate 4 reaches the end of the sliding groove, the block 22 at this time enters the locking hole 20 inside the sliding groove. Because the block 22 is subjected to the elastic force released by the compressed spring 6, the block 22 is pushed into the locking hole 20. And during this process, the connecting rod 24 also slides on the connecting plate 4. In order to prevent the detachment of the buckle 5, the positioning plate 23 on the buckle 5 is fixedly connected to the connecting plate 4 after the block 22 enters the locking hole 20, thereby completing the limit of the buckle 5. At this time, the cover plate 3 rotates under the influence of gravity and is perpendicular to the ground. At this time, the raw materials are started to be transported into the feed inlet 2 on the main body 1.

[0032] In this embodiment, the anti-caking mechanism includes a stirring motor 7, a tank cover 8, a stirring shaft 9 and a fixing rod 10. During use, at this time, the raw materials enter the main body 1. In order to prevent the coagulation of the concrete, the stirring motor 7 on the tank cover 8 is driven at this time, directly driving the stirring shaft 9 to rotate, so that the fixing rod 10 on the stirring shaft 9 starts to stir the concrete inside the main body 1, making it not easy to coagulate, and water can be added to the feed inlet 2 as required.

[0033] In this embodiment, the spraying mechanism includes a stop valve 11, a spray pump 12, a spray rack 13, a lifting motor 14, a lead screw 15, a lifting plate 16 and a connection assembly. When in use, the raw materials are prepared at this time. The stop valve 11 is opened, and all the raw materials start under the action of the spray pump 12 and are sucked out of the main body 1. Subsequently, through the operation of the spray pump 12, the raw materials at this time enter the flexible pipe 17. Since the working places and environments of this setting are quite different, the initial spraying height is also different. At this time, the lifting motor 14 is driven to directly drive the lead screw 15 to rotate, so that the lifting plate 16 slides in the lifting chute 25 inside the spray rack 13, and the driven head 27 at one end of the flexible pipe 17 also rises and falls under the action of the lifting plate 16. At this time, the extension rod 18 can be taken out from the placement box 26 inside the spray rack 13 as appropriate, and then the extension rod 18 is connected to the flexible pipe 17 installed inside the lifting plate 16. At this time, the driving head 28 on the extension rod 18 is in threaded engagement with the driven head 27 on the flexible pipe 17. And during this process, the inner pipe 29 in the extension rod 18 enters the driven head 27, reducing the damage to the thread between the driving head 28 and the driven head 27 by the concrete. This device can be installed on a vehicle for movement.

[0034] Embodiment 2:

[0035] In summary, when in use, raw materials are introduced into the main body 1, and the cover plate 3 is pulled. The sliders 21 on the cover plate 3 and the connecting plate 4 slide in the sliding groove of the feed port 2, and the block 22 also slides in the sliding groove at the same time. When the connecting plate 4 reaches the tail end of the sliding groove, the block 22 enters the clamping hole 20 inside the sliding groove. Because the block 22 is subjected to the elastic force released by the compressed spring 6, the block 22 is pushed into the clamping hole 20, and in this process, the connecting rod 24 also slides on the connecting plate 4, and in order to prevent The stop buckle 5 is disengaged. At this time, the positioning plate 23 on the buckle 5 is fixedly connected with the connecting plate 4 after the block 22 enters the clamping hole 20, thereby completing the limit of the buckle 5. At this time, the cover plate 3 is affected by gravity and rotates and is perpendicular to the ground. At this time, the raw materials are conveyed to the feed port 2 on the main body 1. Then, in order to prevent the raw materials from condensing, the stirring motor 7 on the tank cover 8 is driven to directly drive the stirring shaft 9 to rotate, so that the fixed rod 10 on the stirring shaft 9 starts to stir the concrete inside the main body 1, making it less likely to condense, and depending on the situation, it can be Water is added to the feed port 2, and finally the injection is performed. The stop valve 11 is opened, and all the raw materials are sucked out of the main body 1 under the action of the injection pump 12, and then the injection pump 12 is operated. At this time, the raw materials enter the flexible tube 17. Since the working place and environment of this setting are very different, the initial injection height is also different. At this time, the lifting motor 14 drives and directly drives the lead screw 15 to rotate, so that the lifting plate 16 slides in the lifting slot 25 inside the injection frame 13, and the driven head 27 at one end of the flexible tube 17 is also The lifting plate 16 is used for lifting and lowering. At this time, the outrigger 18 can be taken out from the placement box 26 inside the injection rack 13 according to the situation, and then the outrigger 18 is connected to the flexible tube 17 installed inside the lifting plate 16. At this time, the active head 28 on the outrigger 18 is threadedly engaged with the driven head 27 on the flexible tube 17, and in this process, the inner tube 29 in the outrigger 18 enters the driven head 27, reducing the damage of concrete to the threads between the active head 28 and the driven head 27. The device can be installed on a vehicle for movement.

[0036] In all the schemes mentioned above, the connection between two parts can be selected according to actual conditions by welding, bolt and nut matching connection, bolt or screw connection or other well-known connection methods, which are not described one by one here. In the above, all fixed connections are preferably welded. Although the embodiments of the utility model have been shown and described, it can be understood by ordinary technicians in this field that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the utility model. The scope of the utility model is defined by the attached claims and their equivalents.
