Description

Technical Field

[0001] The invention relates to the technical field of cement mixing, in particular to a cement-soil mixing device with an automatic proportioning function. Background Art

[0002] Cement soil is made of extra-fine sand or sandy loam as the main raw material, with a small amount of cement, admixtures and an appropriate amount of water added and mixed evenly. Finally, special machinery and equipment are used to press it into plates of different specifications. After a period of watering and curing, it can be used as a building material. Cement soil is mainly used for channel anti-seepage and supporting projects such as bridges, culverts, and gates of small-scale farmland water conservancy projects. It is especially suitable for areas where sand and gravel are scarce, because the outstanding advantages of cement soil are that it can be obtained locally, the price is low, and there are significant economic benefits.

[0003] At present, cement soil is mostly mixed by traditional slurry mixing method, that is, deep mixing method. This mixing method easily leads to the problem of high density at the bottom and low density at the top. It requires manual turning and the mixing efficiency is not high. Summary of the invention

[0004] The purpose of the present invention is to provide a cement-soil mixing device with an automatic proportioning function to solve the problems raised in the prior art.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical scheme: a cement-soil mixing device with automatic proportioning function, comprising an equipment support and an automatic feeding pipeline, a mixing bin is installed on the equipment support, a bin cover is arranged on the mixing bin, a feeding port is opened on the bin cover, a discharge port is opened at the bottom of the mixing bin, an opening and closing mechanism is also arranged at the bottom of the mixing bin, the opening and closing mechanism blocks the discharge port, a rotating sealing disk is arranged at the top of the mixing bin, a plurality of stirring mechanisms are arranged on the rotating sealing disk, a vibrating mechanism is also arranged in the middle of the mixing bin, the automatic feeding pipeline extends into the mixing bin through the feeding port, the opening and closing mechanism at the bottom of the mixing bin is closed, and an appropriate amount of sandy loam, cement, admixture and water are poured into the mixing bin through the automatic feeding pipeline, the control system enables the first servo motor to be powered on, the first servo motor drives the active bevel gear to rotate, and the active bevel gear drives the stirring mechanism to stir and mix the cement soil.

[0006] Furthermore, an inner conical gear ring is integrally provided in the middle of the rotating sealing disk, a through groove is opened in the middle of the rotating sealing disk, the through groove is connected to the feed port, and several stirring mechanisms are evenly distributed and annularly installed on the rotating sealing disk, each stirring mechanism includes a small mounting disk, the small mounting disk is rotatably connected to the rotating sealing disk, the rotating sealing disk is rotatably connected to the stirring bin, and the small mounting disk is rotatably connected to the rotating sealing disk, which can prevent dust raised by cement soil during the mixing process from entering the interior of the machine bin cover.

[0007] Furthermore, each of the stirring mechanisms includes a pair of stirring tubes, which are symmetrically arranged at the bottom of the small mounting plate. The top side of each stirring tube is connected to the inside of the stirring chamber through a short tube. A planetary gear is integrally arranged above the small mounting plate. The active bevel gear drives the inner conical ring gear to rotate. Since the inner conical ring gear is integrally connected to the rotating sealing plate, the rotating sealing plate rotates at the top of the stirring chamber, and all the stirring mechanisms are driven to rotate by the rotating sealing plate. The active bevel gear also drives the outer annular ring gear to rotate, and the rotation direction of the annular ring gear is opposite to that of the rotating sealing plate.

[0008] Furthermore, each of the stirring mechanisms also includes a rotating shaft, on which an auger is provided, and paddle wheels and driving gears are respectively provided at both ends of the rotating shaft. The rotating shaft passes through a small mounting plate and a planetary gear, and the auger is located in the stirring tube, and the paddle wheel is located at the bottom of the stirring tube, and the driving gear is located at the top of the planetary gear. The annular gear ring drives the planetary gear to rotate, and because the movement directions of the planetary gear and the annular gear ring are opposite, the planetary gear is differentially accelerated. Therefore, the stirring mechanism rotates while also revolving, and the stirring range of the stirring tube forms an annular cylindrical shape in the stirring chamber.

[0009] Furthermore, a small bracket is provided on the upper part of each stirring mechanism corresponding to the rotating sealing disk, and a fixed gear is fixedly installed on the small bracket. Each of the fixed gears is meshed with two driving gears in the same stirring mechanism. Since the stirring mechanism is in a state of self-rotation, the fixed gear and the stirring mechanism revolve simultaneously with the rotating sealing disk, so the fixed gear and the stirring mechanism are relatively stationary. When the stirring mechanism rotates, the two driving gears mesh and roll on the surface of the fixed gear. When the stirring tube stirs the cement soil, the rotating shaft inside it is also rotating, and the rotating shaft drives the auger and the paddle wheel to rotate.

[0010] Furthermore, a first servo motor is installed on the machine cover, and a sprocket and an active bevel gear are coaxially arranged on the motor shaft of the first servo motor. An annular gear ring is rotatably installed inside the machine cover, and the inner ring of the annular gear ring is meshed with all the planetary gears. Bevel teeth are provided on the top of the annular gear ring, and one side of the active bevel gear is meshed with the inner conical gear ring, and the other side of the active bevel gear is meshed with the bevel teeth. The paddle wheel scrapes the cement soil at the bottom of the mixing bin to the bottom of the mixing tube, and the auger draws the cement soil at the bottom of the mixing tube into the short tube at the upper end for discharge. By setting a stirring mechanism that rotates and revolves at the same time, the stirring range of the stirring tube is expanded, and the stirring range of the stirring tube forms an annular cylindrical shape to achieve stirring of the plane layer. By setting the auger, the cement soil at the bottom of the mixing bin is drawn to the upper part, and flipping from the bottom to the upper part is achieved, so that the stirring of the cement soil is more uniform.

[0011] Furthermore, a rotating sleeve is rotatably installed on the outer ring of the machine chamber cover corresponding to the feed port, a toothed disc is arranged on the outer side of the rotating sleeve, a chain is connected between the sprocket and the toothed disc, a continuous wavy annular groove is opened on the inner ring of the rotating sleeve, and the vibrating mechanism includes a vibrating rod, and the vibrating rod is extended into the mixing chamber through the feed port, and a driven pin is arranged on the upper part of the vibrating rod, and the driven pin is slidably arranged in the wavy annular groove, and the first servo motor drives the rotating sleeve to rotate through the sprocket and the chain, and the vibrating rod cannot rotate under the restriction of the rotation limiting frame, and can only slide up and down, and the rotating sleeve drives the driven pin to move by the wavy annular groove, thereby driving the vibrating rod to move up and down.

[0012] Furthermore, the vibrating mechanism also includes several vibrating plates, several of the vibrating plates are located inside the mixing chamber, and several of the vibrating plates are evenly distributed on the vibrating rod. The center thickness of each vibrating plate is greater than the edge thickness. A limiting slide groove is provided on the top of the vibrating rod, and a rotation limiting frame is provided on the top of the chamber cover. The limiting slide groove is slidably connected to the rotation limiting frame, and the vibrating rod drives all the vibrating plates to reciprocate up and down. Since the upper and lower sides of the vibrating plate are conical surfaces, the cement soil can be pushed to the edge during the vibration process, so that the cement soil is pushed into the range that the mixing tube can mix, thereby further improving the mixing efficiency of the cement soil.

[0013] Furthermore, the opening and closing mechanism includes several unloading baffles and an opening and closing transmission disk, the opening and closing transmission disk is rotatably installed on the bottom of the mixing bin, a pin is provided on the upper part of each unloading baffle, and a slider is provided on the lower part of each unloading baffle. The bottom of the mixing bin is provided with an inclined slide groove with the same number as the unloading baffle, and the pin is slidably installed in the inclined slide groove, and the opening and closing transmission disk is provided with a straight slide groove with the same number as the unloading baffle, and the slider is slidably installed in the straight slide groove.

[0014] Furthermore, the opening and closing mechanism also includes a second servo motor and an opening gear, the opening gear is installed on the motor shaft of the second servo motor, and the outer ring of the opening and closing transmission disk is provided with spur teeth, and the opening gear is meshed with the spur teeth outside the opening and closing transmission disk. After the cement soil is mixed, the control system enables the second servo motor to be energized and work, and the second servo motor uses the opening gear to drive the opening and closing transmission disk to rotate, and the opening and closing transmission disk controls the opening or closing of the unloading baffle. After the unloading baffle is opened, the mixed cement soil flows out from the unloading port under the action of gravity.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. By setting a stirring mechanism that rotates and revolves at the same time, the stirring range of the stirring tube is expanded. The stirring range of the stirring tube forms an annular cylindrical shape to achieve plane layer stirring. Through the setting of the auger, the cement soil at the bottom of the mixing bin is pumped to the upper part to achieve turning from the bottom to the upper part, making the mixing of the cement soil more uniform.

[0017] 2. The vibrating rod drives all the vibrating plates to reciprocate up and down. Since the upper and lower sides of the vibrating plates are conical surfaces, the cement soil can be pushed to the edge during the vibration process, so that the cement soil is pushed into the mixing range of the mixing tube, further improving the mixing efficiency of the cement soil.

[0028] An inner conical gear ring 6 is integrally arranged in the middle of the rotating sealing disk 7, a through groove is opened in the middle of the rotating sealing disk 7, and the through groove is connected to the feed port. Several stirring mechanisms 8 are evenly distributed and annularly installed on the rotating sealing disk 7, each stirring mechanism 8 includes a small mounting disk 10, and the small mounting disk 10 is rotatably connected to the rotating sealing disk 7. Each stirring mechanism 8 includes a pair of stirring tubes 12, and the pair of stirring tubes 12 are symmetrically arranged at the bottom of the small mounting disk 10. One side of the top of each stirring tube 12 is connected to the inside of the stirring bin 1 through a short tube, and a planetary gear is integrally arranged above the small mounting disk 10. 11. The rotating sealing disk 7 is sealed and rotatably connected to the mixing chamber 1. The small mounting disk 10 is sealed and rotatably connected to the rotating sealing disk 7, which can prevent dust raised during the mixing of cement soil from entering the interior of the chamber cover 2. The active bevel gear 4 drives the inner conical gear ring 6 to rotate. Since the inner conical gear ring 6 is integrally connected to the rotating sealing disk 7, the rotating sealing disk 7 rotates on the top of the mixing chamber 1. All the mixing mechanisms 8 are driven to rotate by the rotating sealing disk 7. The active bevel gear 4 also drives the outer annular gear ring 5 to rotate. The rotation direction of the annular gear ring 5 is opposite to that of the rotating sealing disk 7.

[0029] Each stirring mechanism 8 also includes a rotating shaft 13, on which an auger 15 is arranged, and paddle wheels 16 and driving gears 14 are arranged at both ends of the rotating shaft 13, respectively. The rotating shaft 13 passes through the small mounting plate 10 and the planetary gear 11, and the auger 15 is located in the stirring tube 12, the paddle wheel 16 is located at the bottom of the stirring tube 12, and the driving gear 14 is located at the top of the planetary gear 11. The rotating sealing plate 7 is provided with a small bracket corresponding to the upper part of each stirring mechanism 8, and a fixed gear 9 is fixedly installed on the small bracket. Each fixed gear 9 is meshed with two driving gears 14 in the same stirring mechanism 8. A first servo motor 3 is installed on the machine cover 2, and a sprocket and an active bevel gear 4 are coaxially arranged on the motor shaft of the first servo motor 3. An annular gear ring 5 is rotatably installed inside the machine cover 2, and the inner ring of the annular gear ring 5 is meshed with all the planetary gears 11. Bevel teeth are provided on the top of the annular gear ring 5, and one side of the active bevel gear 4 is meshed with the inner conical gear ring 6, and the other side of the active bevel gear 4 is meshed with the bevel teeth.

[0030] The annular gear ring 5 drives the planetary gear 11 to rotate. Since the planetary gear 11 moves in opposite directions to the annular gear ring 5, the planetary gear 11 is differentially accelerated. Therefore, the stirring mechanism 8 rotates while also revolving. The stirring range of the stirring tube 12 forms an annular cylindrical shape in the stirring chamber 1. Since the stirring mechanism 8 is in a state of self-rotation, the fixed gear 9 and the stirring mechanism 8 revolve simultaneously with the rotating sealing disk 7. Therefore, the fixed gear 9 and the stirring mechanism 8 are relatively stationary. When the stirring mechanism 8 rotates, the two driving gears 14 mesh and roll on the surface of the fixed gear 9. When the stirring tube 12 stirs the cement soil While mixing, the rotating shaft 13 inside it is also rotating, and the rotating shaft 13 drives the auger 15 and the paddle wheel 16 to rotate. The paddle wheel 16 scrapes the cement soil at the bottom of the mixing bin 1 to the bottom of the mixing tube 12, and the auger 15 draws the cement soil at the bottom of the mixing tube 12 to the short tube at the upper end for discharge. By setting the stirring mechanism 8 that rotates and revolves at the same time, the stirring range of the stirring tube 12 is expanded, and the stirring range of the stirring tube 12 forms an annular cylindrical shape to achieve the stirring of the plane layer. By setting the auger 15, the cement soil at the bottom of the mixing bin 1 is drawn to the upper part, and the turning from the bottom to the upper part is achieved, so that the mixing of the cement soil is more uniform.

[0031] A rotating sleeve 20 is rotatably installed on the outer ring of the machine chamber cover 2 corresponding to the feed port, a toothed disc is arranged on the outer side of the rotating sleeve 20, a chain 22 is connected between the sprocket and the toothed disc, a continuous wavy annular groove is provided on the inner ring of the rotating sleeve 20, and a vibrating mechanism includes a vibrating rod 17, which extends into the mixing chamber 1 through the feed port, and a driven pin 21 is provided on the upper part of the vibrating rod 17, and the driven pin 21 is slidably arranged in the wavy annular groove, and the vibrating mechanism also includes a plurality of vibrating disks 18, which are located inside the mixing chamber 1, and are evenly distributed on the vibrating rod 17, and the center thickness of each vibrating disk 18 is greater than the edge thickness, and a limiting sliding plate is provided on the top of the vibrating rod 17. The top of the machine cover 2 is provided with a rotation limiting frame 19, and the limiting slide groove is slidably connected with the rotation limiting frame 19. The first servo motor 3 drives the rotating sleeve 20 to rotate through the sprocket and the chain 22. The vibrating rod 17 cannot rotate under the restriction of the rotation limiting frame 19 and can only slide up and down. The rotating sleeve 20 drives the driven pin 21 to move by the wavy annular groove, thereby driving the vibrating rod 17 to move up and down. The vibrating rod 17 drives all the vibrating disks 18 to reciprocate up and down. Since the upper and lower sides of the vibrating disk 18 are conical surfaces, the cement soil can be pushed to the edge during the vibration process, so that the cement soil is pushed into the range that the mixing tube 12 can mix, thereby further improving the mixing efficiency of the cement soil.

[0032] The opening and closing mechanism includes several discharge baffles 26 and an opening and closing transmission disk 25, the opening and closing transmission disk 25 is rotatably mounted on the bottom of the mixing bin 1, a pin is arranged on the upper part of each discharge baffle 26, and a slider is arranged on the lower part of each discharge baffle 26. The bottom of the mixing bin 1 is provided with an inclined slide groove with the same number as the discharge baffle 26, and the pin is slidably mounted in the inclined slide groove, and the opening and closing transmission disk 25 is provided with a straight slide groove with the same number as the discharge baffle 26, and the slider is slidably mounted in the straight slide groove. The opening and closing mechanism also includes a second servo motor 23 and a bin opening gear 2 4. The opening gear 24 is installed on the motor shaft of the second servo motor 23. The outer ring of the opening and closing transmission disk 25 is provided with straight teeth. The opening gear 24 meshes with the straight teeth outside the opening and closing transmission disk 25. After the cement soil is mixed, the control system enables the second servo motor 23 to be powered on. The second servo motor 23 uses the opening gear 24 to drive the opening and closing transmission disk 25 to rotate. The opening and closing transmission disk 25 controls the unloading damper 26 to open or close. After the unloading damper 26 is opened, the mixed cement soil flows out from the unloading port under the action of gravity.

[0033] The working principle of the present invention is as follows: the opening and closing mechanism at the bottom of the mixing bin 1 is closed, and an appropriate amount of sandy loam, cement, admixture and water are poured into the mixing bin 1 through an automatic feeding pipe, and the control system enables the first servo motor 3 to be powered on, the first servo motor 3 drives the active bevel gear 4 to rotate, and the active bevel gear 4 drives the stirring mechanism 8 to stir and mix the cement soil.

[0034] The rotating sealing disk 7 is sealed and rotatably connected to the mixing bin 1, and the small mounting disk 10 is sealed and rotatably connected to the rotating sealing disk 7, which can prevent dust raised during the mixing of cement soil from entering the interior of the machine bin cover 2. The active bevel gear 4 drives the inner conical ring gear 6 to rotate. Since the inner conical ring gear 6 is integrally connected to the rotating sealing disk 7, the rotating sealing disk 7 rotates at the top of the mixing bin 1, and all the mixing mechanisms 8 are driven to rotate by the rotating sealing disk 7. The active bevel gear 4 also drives the outer annular ring gear 5 to rotate, and the rotation direction of the annular ring gear 5 is opposite to that of the rotating sealing disk 7.

[0035] The annular gear ring 5 drives the planetary gear 11 to rotate. Since the planetary gear 11 moves in opposite directions to the annular gear ring 5, the planetary gear 11 is differentially accelerated. Therefore, the stirring mechanism 8 rotates while also revolving. The stirring range of the stirring tube 12 forms an annular cylindrical shape in the stirring chamber 1. Since the stirring mechanism 8 is in a state of self-rotation, the fixed gear 9 and the stirring mechanism 8 revolve simultaneously with the rotating sealing disk 7. Therefore, the fixed gear 9 and the stirring mechanism 8 are relatively stationary. When the stirring mechanism 8 rotates, the two driving gears 14 mesh and roll on the surface of the fixed gear 9. When the stirring tube 12 stirs the cement soil While mixing, the rotating shaft 13 inside it is also rotating, and the rotating shaft 13 drives the auger 15 and the paddle wheel 16 to rotate. The paddle wheel 16 scrapes the cement soil at the bottom of the mixing bin 1 to the bottom of the mixing tube 12, and the auger 15 draws the cement soil at the bottom of the mixing tube 12 to the short tube at the upper end for discharge. By setting the stirring mechanism 8 that rotates and revolves at the same time, the stirring range of the stirring tube 12 is expanded, and the stirring range of the stirring tube 12 forms an annular cylindrical shape to achieve the stirring of the plane layer. By setting the auger 15, the cement soil at the bottom of the mixing bin 1 is drawn to the upper part, and the turning from the bottom to the upper part is achieved, so that the mixing of the cement soil is more uniform.

[0036] The first servo motor 3 drives the rotating sleeve 20 to rotate through the sprocket and chain 22. The vibrating rod 17 cannot rotate under the restriction of the rotation limiting frame 19 and can only slide up and down. The rotating sleeve 20 uses the wavy annular groove to drive the driven pin 21 to move, thereby driving the vibrating rod 17 to move up and down. The vibrating rod 17 drives all the vibrating plates 18 to reciprocate up and down. Since the upper and lower sides of the vibrating plate 18 are conical surfaces, the cement soil can also be pushed to the edge during the vibration process, so that the cement soil is pushed into the mixing range of the mixing tube 12, further improving the mixing efficiency of the cement soil.

[0037] After the cement soil is mixed, the control system powers on the second servo motor 23, and the second servo motor 23 drives the opening and closing transmission disk 25 to rotate by the opening gear 24. The opening and closing transmission disk 25 controls the opening or closing of the discharge damper 26. After the discharge damper 26 is opened, the mixed cement soil flows out from the discharge port under the action of gravity.
