[0001] This utility model relates to the technical field of mining rapid-setting spraying material devices, specifically a transmission device for mining rapid-setting spraying materials. Background Technology

[0002] The conveying device for quick-setting sprayed materials in mining is a key piece of equipment used to efficiently transport quick-setting materials (such as concrete and mortar) to the spraying location in mining, tunnel and other engineering projects.

[0003] Existing equipment often results in the accumulation of quick-setting materials at the feed inlet when the materials are poured into the equipment. This leads to poor material mixing and requires frequent cleaning by staff, wasting time. Therefore, we propose a conveying device for quick-setting sprayed materials used in mining. Utility Model Content

The feeding assembly includes four sets of symmetrically opened sliding grooves on the inner wall of the equipment housing. Each of the four sets of sliding grooves has a slider slidably connected to its inner wall. Each of the four sets of sliders has a spring fixedly connected to its top. The end of each of the four sets of springs away from the slider is fixedly connected to the top of the inner wall of the sliding groove. A filter screen is fixedly connected to the opposite side of each of the four sets of sliders. Each of the sliders has four sets of symmetrically fixed protrusions at equal intervals on its bottom.

[0006] Furthermore, the transmission assembly includes two sets of rotating shafts symmetrically rotatably connected to the inner wall of the equipment housing. Four sets of cams are coaxially fixedly connected to the outer wall of the two sets of rotating shafts near the protrusion. The cams are adapted to the protrusion. Two sets of stirring rollers are symmetrically rotatably connected to the bottom of the inner wall of the equipment housing.

[0007] Furthermore, a first synchronous pulley, a second synchronous pulley, a third synchronous pulley, and a fourth synchronous pulley are rotatably connected to the front side of the equipment housing. The first and second synchronous pulleys are connected by a first synchronous belt, the first and fourth synchronous pulleys are connected by a third synchronous belt, and the fourth and third synchronous pulleys are connected by a second synchronous belt. A cover plate is fixedly connected to the front side of the equipment housing, and a motor is fixedly connected to the front side of the cover plate. The output end of the motor is connected to the fourth synchronous pulley.

[0008] Furthermore, the first synchronous pulley is coaxially fixed with the left rotating shaft, the second synchronous pulley is coaxially fixed with the right rotating shaft, the fourth synchronous pulley is coaxially fixed with the left stirring roller, and the third synchronous pulley is coaxially fixed with the right stirring roller.

[0009] Furthermore, the bottom of the equipment housing is provided with a discharge port, and the top of the equipment housing is fixedly connected with a feed port.

[0010] Furthermore, the transport assembly includes a base plate fixed to four sets of opposing support columns. A conveying roller is fixedly connected to the top of the base plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: By setting up a device shell, feeding component, transmission component and transport component, when in use, the device shell is placed on the ground and then the quick-setting material is put in sequentially from the feed port. Then the motor is started. Driven by the motor, the cam will contact the protrusion to make the filter screen vibrate up and down. During the vibration, the quick-setting material is transported to the mixing roller in an orderly manner. Through the mixing roller, the material is finally transported to the next device through the conveying roller. Through the above design, it is possible to prevent the quick-setting material from accumulating during mixing and stirring, which would affect subsequent mixing and use. Attached Figure Description

The feeding assembly 2 includes four sets of sliding grooves 6 symmetrically formed on the inner wall of the housing 1, with sliders 10 slidably connected to the inner walls of the four sets of sliding grooves 6, and springs 11 fixedly connected to the tops of the four sets of sliders 10. The ends of the four sets of springs 11 away from the sliders 10 are connected to the sliding grooves. The top of the inner wall of the device housing 1 is fixedly connected to the filter screen 9 on the opposite side of the four sets of sliders 10. Four sets of protrusions 15 are symmetrically fixed at equal intervals on the bottom of the sliders 10. The transmission assembly 3 includes two sets of rotating shafts 12 symmetrically rotatably connected to the inner wall of the device housing 1. Four sets of cams 14 are coaxially fixedly connected to the outer wall of the two sets of rotating shafts 12 near the protrusions 15. The cams 14 are adapted to the protrusions 15. Two sets of stirring rollers 13 are symmetrically rotatably connected to the bottom of the inner wall of the device housing 1. A first synchronous wheel 16 and a second synchronous wheel 19 are rotatably connected to the front side of the device housing 1. A third synchronous pulley 20 is rotatably connected to the front side of the outer casing 1, and a fourth synchronous pulley 22 is rotatably connected to the front side of the outer casing 1. A first synchronous pulley 16 and a second synchronous pulley 19 are connected by a first synchronous belt 18, a first synchronous pulley 16 and a fourth synchronous pulley 22 are connected by a third synchronous belt 24, and a fourth synchronous pulley 22 and a third synchronous pulley 20 are connected by a second synchronous belt 21. A cover plate is fixedly connected to the front side of the outer casing 1, and a motor is fixedly connected to the front side of the cover plate. The output end of the motor is connected to the fourth synchronous pulley 22. The first synchronous pulley 16 is coaxially fixed to the left rotating shaft 12, and the second synchronous pulley 19 is rotatably connected to the left rotating shaft 12. 9 is coaxially fixed with the right rotating shaft 12, the fourth synchronous wheel 22 is coaxially fixed with the left stirring roller 13, the third synchronous wheel 20 is coaxially fixed with the right stirring roller 13, the bottom of the equipment shell 1 is provided with a discharge port 8, the top of the equipment shell 1 is fixedly connected with a feed port 17, the transport component 5 includes a base plate 23 fixed to four sets of support columns 4 facing each other, the top of the base plate 23 is fixedly connected with a conveying roller, the inner wall of the conveying roller is rotatably connected with an auger blade, the right outer wall of the conveying roller is fixedly connected with a motor, the output end of the motor is connected to the auger blade, and the top of the conveying roller is provided with a hole that matches the discharge port 8; Specifically, the equipment casing 1 is first placed stably on the work site using the four sets of support columns 4 at the bottom to ensure the stability of the entire device. Quick-setting materials such as concrete and mortar are poured in through the feed inlet 17 at the top of the equipment casing 1. The materials first fall onto the filter screen 9 of the feeding assembly 2. The motor on the front cover plate of the equipment casing 1 is then started. The motor output directly drives the fourth synchronous pulley 22 to rotate. When the fourth synchronous pulley 22 rotates, it drives the first synchronous pulley 16 to rotate via the third synchronous belt 24. The first synchronous pulley 16 then drives the second synchronous pulley 19 to rotate via the first synchronous belt 18. Since the first synchronous pulley 16 is coaxially fixed with the left-side rotating shaft 12, and the second synchronous pulley 19 is coaxially fixed with the right-side rotating shaft 12, the two sets of rotating shafts 12 will rotate synchronously. When the rotating shafts 12 rotate, the four sets of cams 14 on their outer walls will rotate synchronously. During the rotation of cam 14, it continuously contacts the protrusion 15 at the bottom of slider 10. When the protrusion of cam 14 touches the protrusion 15, it pushes the protrusion 15 upward, causing slider 10 to slide upward within the groove 6. At this time, the spring 11 at the top of slider 10 is stretched. When the protrusion of cam 14 moves away from the protrusion 15, the stretched spring 11 contracts and returns to its original position, pulling slider 10 downward within the groove 6. As slider 10 slides up and down, it causes the four sets of filter screens 9 connected to each other to vibrate together. The vibration of filter screen 9 can "shake off" the quick-setting material falling on it, preventing material accumulation, and at the same time, it allows the material to pass evenly through the mesh of filter screen 9 and fall into the lower part of the equipment housing 1. While the fourth synchronous pulley 22 rotates, it also drives the third synchronous pulley 20 to rotate through the second synchronous belt 21. Because the fourth synchronous wheel 22 is coaxially fixed with the left stirring roller 13 and the third synchronous wheel 20 is coaxially fixed with the right stirring roller 13, the two sets of stirring rollers 13 will rotate synchronously. The quick-setting material falling from the filter screen 9 will fall directly between the two sets of stirring rollers 13. The rotating stirring rollers 13 will mix and stir the material like a "stirring stick", making the material more evenly mixed and avoiding local lumps. The evenly mixed material will fall from the discharge port 8 at the bottom of the equipment shell 1. The top of the conveying roller of the transport component 5 has a hole that matches the discharge port 8, so the material will fall accurately into the conveying roller. Start the motor on the right outer wall of the conveying roller, and the motor output will drive the auger blades inside the conveying roller to rotate. When the auger blades rotate, they will act like a "spiral pusher", smoothly conveying the material inside the conveying roller from one end to the other end, and finally sending it to the next stage of construction equipment such as the spraying machine, completing the entire transmission process.

[0016] Working principle: First, the equipment casing 1 is placed stably on the work site using the four sets of support columns 4 at the bottom to ensure the stability of the entire device. Quick-setting materials such as concrete and mortar are poured in through the feed inlet 17 at the top of the equipment casing 1. The material first falls onto the filter screen 9 of the feeding assembly 2. The motor on the front cover plate of the equipment casing 1 is then started. The motor output directly drives the fourth synchronous pulley 22 to rotate. When the fourth synchronous pulley 22 rotates, it drives the first synchronous pulley 16 to rotate via the third synchronous belt 24. The first synchronous pulley 16 then drives the second synchronous pulley 19 to rotate via the first synchronous belt 18. Since the first synchronous pulley 16 is coaxially fixed with the left-side rotating shaft 12, and the second synchronous pulley 19 is coaxially fixed with the right-side rotating shaft 12, the two sets of rotating shafts 12 will rotate synchronously. When the rotating shafts 12 rotate, the four sets of cams 14 on their outer walls will rotate synchronously. During the rotation of cam 14, it continuously contacts the protrusion 15 at the bottom of slider 10. When the protrusion of cam 14 touches the protrusion 15, it pushes the protrusion 15 upward, causing slider 10 to slide upward within the groove 6. At this time, the spring 11 at the top of slider 10 is stretched. When the protrusion of cam 14 moves away from the protrusion 15, the stretched spring 11 contracts and returns to its original position, pulling slider 10 downward within the groove 6. As slider 10 slides up and down, it causes the four sets of filter screens 9 connected to each other to vibrate together. The vibration of filter screen 9 can "shake off" the quick-setting material falling on it, preventing material accumulation, and at the same time, it allows the material to pass evenly through the mesh of filter screen 9 and fall into the lower part of the equipment housing 1. While the fourth synchronous pulley 22 rotates, it also drives the third synchronous pulley 20 to rotate through the second synchronous belt 21. Because the fourth synchronous wheel 22 is coaxially fixed with the left stirring roller 13 and the third synchronous wheel 20 is coaxially fixed with the right stirring roller 13, the two sets of stirring rollers 13 will rotate synchronously. The quick-setting material falling from the filter screen 9 will fall directly between the two sets of stirring rollers 13. The rotating stirring rollers 13 will mix and stir the material like a "stirring stick", making the material more evenly mixed and avoiding local lumps. The evenly mixed material will fall from the discharge port 8 at the bottom of the equipment shell 1. The top of the conveying roller of the transport component 5 has a hole that matches the discharge port 8, so the material will fall accurately into the conveying roller. Start the motor on the right outer wall of the conveying roller, and the motor output will drive the auger blades inside the conveying roller to rotate. When the auger blades rotate, they will act like a "spiral pusher", smoothly conveying the material inside the conveying roller from one end to the other end, and finally sending it to the next stage of construction equipment such as the spraying machine, completing the entire transmission process.
