[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Specifically: As Figure 1-6As shown in the figure, a mine shotcreting machine includes a shotcreting machine body 1, a slurry bucket 2 and a sealing cover 3: the slurry bucket 2 is installed inside the shotcreting machine body 1, the sealing cover 3 is fitted on the outer wall of the top of the slurry bucket 2, a homogenizing mixing mechanism 4 is arranged inside the slurry bucket 2, a pre-mixing mechanism 5 is arranged above the sealing cover 3, and a portable cleaning mechanism 6 is arranged on the side of the sealing cover 3;

[0024] The homogenizing mixing mechanism 4 includes a first hydraulic motor 41, a transmission shaft 42, a first stirring blade 43 and a second stirring blade 44. The first hydraulic motor 41 is installed on the outer wall of the top of the sealing cover 3, the output end of the first hydraulic motor 41 is connected to the outer wall of the top of the transmission shaft 42. The first stirring blade 43 and the second stirring blade 44 are arranged at staggered intervals outside the transmission shaft 42 inside the slurry bucket 2. The first stirring blade 43 is arranged in a spiral structure, the second stirring blade 44 is arranged in a strip-shaped plate structure, and a filter screen plate 45 is embedded on the outer wall of the side of the second stirring blade 44;

[0025] When it is necessary to homogenize and mix the slurry inside the slurry bucket 2, only the first hydraulic motor 41 needs to be turned on at this time. After the first hydraulic motor 41 is turned on, its output end automatically rotates and synchronously drives the transmission shaft 42 to rotate. Then, the rotation of the transmission shaft 42 will automatically drive the first stirring blade 43 and the second stirring blade 44 to rotate. Here, the first stirring blade 43 is arranged in a spiral structure so that when it rotates, it can convey the slurry inside the slurry bucket 2 up and down, thereby achieving the effect of longitudinal mixing. The second stirring blade 44 is arranged in a strip-shaped plate structure so that when it rotates, it can automatically mix the slurry inside the slurry bucket 2 in a transverse trajectory. With the filter screen plate 45 arranged inside it, it can also achieve the effect of breaking and mixing the slurry when it rotates. Therefore, through the above design of combining horizontal and vertical directions to mix the slurry, the rate of slurry mixing uniformity is greatly accelerated.

[0026] The premixing mechanism 5 includes a material injection pipe 51, a premixing box 52, a support frame 53, a guide plate 54, a stirring roller 55 and a support shaft 56. The top outer wall of the sealing cover 3 is penetrated with the material injection pipe 51, the top outer wall of the material injection pipe 51 is connected with the premixing box 52, and the top outer wall of the premixing box 52 is provided with a support frame 53. The inner walls of both sides of the support frame 53 are symmetrically provided with guide plates 54, and the guide plates 54 are inclined. Two groups of stirring rollers 55 are provided inside the premixing box 52, and the two groups of stirring rollers 55 are arranged outside the support shaft 56. One end of the support shaft 56 The first group of support shafts 56 are connected to the output end of the second hydraulic motor 57, the other end of the first group of support shafts 56 is connected to the side outer wall of the first transmission gear 58, one end of the second group of support shafts 56 is rotatably installed with the side inner wall of the premixing box 52, the other end of the second group of support shafts 56 is connected to the side outer wall of the second transmission gear 59, the second hydraulic motor 57 is connected to the side outer wall of the premixing box 52, the first transmission gear 58 and the second transmission gear 59 are both rotatably installed with the side outer wall of the premixing box 52, and the first transmission gear 58 and the second transmission gear 59 are meshed with each other;

[0027] When the slurry needs to be poured into the slurry barrel 2, it is necessary to start the second hydraulic motor 57 in advance. After the second hydraulic motor 57 is turned on, it will automatically drive the first group of support shafts 56 to rotate. Subsequently, the rotation of the first group of support shafts 56 will drive the first transmission gear 58 to rotate. The rotation of the first transmission gear 58 will automatically drive the second transmission gear 59 to drive the second group of support shafts 56 to rotate. The synchronous opposite rotation of the two groups of support shafts 56 will automatically drive the two groups of stirring rollers 55 to rotate in the opposite direction. When pouring the slurry, it is only necessary to pour the slurry into the inside of the support frame 53. The two groups of inclined guide plates 54 here have a guiding effect on the slurry. When the slurry enters the middle position of the two groups of stirring rollers 55 and passes down, the premixing effect is automatically achieved. Especially when the slurry is two liquids, the premixing effect is better.

[0028] The portable cleaning mechanism 6 includes a first mounting ring 61, a second mounting ring 62, threaded holes 63, fastening bolts 64 and nut blocks 65. The first mounting ring 61 is installed on the outer wall of the side at the bottom end of the sealing cover 3, and the second mounting ring 62 is installed on the outer wall of the side at the top end of the slurry bucket 2. Threaded holes 63 are evenly and penetratingly formed on the outer wall of the top ends of the first mounting ring 61 and the second mounting ring 62, and fastening bolts 64 are installed by threading inside the threaded holes 63, and nut blocks 65 are installed by threading on the outside of the fastening bolts 64; when it is necessary to remove the sealing cover 3 from above the slurry bucket 2 for cleaning the slurry bucket 2, at this time, only need to completely screw out the fastening bolts 64 from the nut blocks 65 and the threaded holes 63 at the corresponding positions. Then, the first mounting ring 61 and the second mounting ring 62 change from the locked state to the movable state. Subsequently, directly take out the sealing cover 3 together with the entire homogeneous mixing mechanism 4 and the premixing mechanism 5 from the inside of the slurry bucket 2. Then, the slurry bucket 2 becomes a cavity state, and it can be directly cleaned. The installation principle is the same as the above disassembly principle.

[0029] When the utility model is in use, first, the slurry needs to be poured into the slurry bucket 2. At this time, it is necessary to pre-start the second hydraulic motor 57. Then, after the second hydraulic motor 57 is started, it will automatically drive the first set of support shafts 56 to rotate. Subsequently, the rotation of the first set of support shafts 56 will drive the first transmission gear 58 to rotate. Then, the rotation of the first transmission gear 58 will automatically drive the second transmission gear 59 to drive the second set of support shafts 56 to rotate. Then, the synchronous and opposite rotation of the two sets of support shafts 56 will automatically drive the two sets of stirring rollers 55 to rotate in opposite directions. When pouring the slurry, at this time, only need to pour the slurry into the inside of the support frame 53. Here, the two sets of inclined guide plates 54 play a guiding role for the slurry. Then, when the slurry enters the middle position between the two sets of stirring rollers 55 and passes down, the pre-mixing effect is automatically achieved. Especially when the slurry is two liquids, the pre-mixing effect is better.

[0030] When it is necessary to homogenize and mix the slurry inside the slurry bucket 2, at this time, only need to start the first hydraulic motor 41. After the first hydraulic motor 41 is started, its output end automatically rotates and synchronously drives the transmission shaft 42 to rotate. Then, the rotation of the transmission shaft 42 will automatically drive the first stirring blade 43 and the second stirring blade 44 to rotate. Here, the first stirring blade 43 is set as a spiral structure so that when it rotates, it can convey the slurry inside the slurry bucket 2 up and down, thereby achieving the effect of longitudinal mixing. The second stirring blade 44 is set as a strip-shaped plate structure so that when it rotates, it can automatically achieve the mixing effect of the transverse trajectory of the slurry inside the slurry bucket 2. Cooperating with the filter plate 45 arranged inside it, it can also achieve the effect of dispersing and mixing the slurry when rotating. Then, through the above design of combining the horizontal and vertical directions to mix the slurry, the rate of mixing the slurry evenly is greatly accelerated.

[0031] When it is necessary to remove the sealing cover 3 from above the slurry bucket 2 for cleaning the slurry bucket 2, only the fastening bolt 64 needs to be completely screwed out from the nut block 65 and the threaded hole 63 at the corresponding position at this time. Then, the first mounting ring 61 and the second mounting ring 62 change from the locked state to the movable state. Subsequently, the sealing cover 3 together with the entire homogeneous mixing mechanism 4 and the premixing mechanism 5 are directly taken out from the inside of the slurry bucket 2. Then, the slurry bucket 2 becomes a cavity state and can be directly cleaned. The installation principle is the same as the above disassembly principle.

[0032] Specifically, how the slurry bucket 2 is installed inside the spraying machine body 1 and used in cooperation with other components for spraying Figure 1 has been drawn, and its installation method is the same as the existing combination method without any improvement, so no more description is made.

[0033] At the same time, it is noted here that the above first hydraulic motor 41 and second hydraulic motor 57 can be powered according to the existing operation technical means. Whether it is powered by a power supply component or an external wire, it belongs to the existing conventional operation technical means and will not be described in detail here.

[0034] In addition, it should be understood that although this specification is described according to the embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
