Fig. 1-4 illustrate an automatic discharge dual horizontal axis concrete mixer comprising: the device comprises a barrel body 1000, a stirring assembly 2000, two gears 3000 with the same size, a driving assembly 4000 and a discharging assembly 5000. The barrel body 1000 is internally provided with a stirring cavity 1100, the bottom of the barrel body 1000 is in the shape of two drums, the bottom of the barrel body 1000 is provided with a discharge opening (not shown in the figure), and the discharge opening is positioned at the connecting position of the two drums. Stirring assembly 2000 is located in stirring chamber 1100, stirring assembly 2000 comprises two stirring shafts 2100 arranged in parallel, two ends of stirring shaft 2100 are rotatably connected to two ends of barrel 1000, stirring shaft 2100 is located at the central axis of two barrels of barrel 1000, seven sets of blade assemblies 2200 are axially surrounded on stirring shaft 2100, each blade assembly 2200 comprises a blade 2210 and a connecting rod 2220 with one end fixed on blade 2210, the other end of connecting rod 2220 is perpendicularly fixed on stirring shaft 2100, seven sets of blade assemblies 2200 are arranged in a spiral shape, blade 2210 is provided with a stirring surface 2213, and stirring surface 2213 is parallel to the central axis of connecting rod 2220 and forms an angle of 45 degrees with the central axis of stirring shaft 2100. Two gears 3000 are located at the same end of the two stirring shafts 2100 and outside the barrel 1000, and the two gears 3000 are engaged with each other. The other end of stirring shaft 2100 is provided with a chain wheel 3100, chain wheel 3100 is positioned outside barrel body 1000, driving assembly 4000 drives chain wheel 3100 to rotate through a transmission chain, stirring shaft 2100 positioned on the left side rotates anticlockwise, and stirring shaft 2100 positioned on the right side rotates clockwise when viewed from direction of chain wheel 3100. The discharging assembly 5000 comprises a cylinder 5100 and a discharging door device 5200. The discharge door device 5200 comprises a discharge door arc plate 5210, two discharge door side plates 5220, two rotating shafts 5230, a connecting rod 5240 and a bearing seat 5250, wherein the two discharge door side plates 5220 are fixed at two ends of the discharge door arc plate 5210, the two rotating shafts 5230 are connected in a connecting hole 5221 of the discharge door side plate 5220 and rotatably arranged in the bearing seat 5250, one end of the connecting rod 5240 is fixed at one rotating shaft 5230, the other end of the connecting rod 5240 is fixed at a piston rod of a cylinder 5100, the axial direction of the piston rod is perpendicular to the axial direction of the rotating shaft 5230, and the cylinder 5100 can drive the discharge door arc plate 5210 to cover the discharge opening.
In this embodiment, drive assembly 4000 rotates sprocket 3100 such that agitator shafts 2100 rotate, and both agitator shafts 2100 rotate in the same direction and in opposite directions by the action of the two meshing gears 3000. In the rotating process of the stirring shaft 2100, on the one hand, the materials to be mixed continuously move back and forth in the direction perpendicular to the two stirring shafts 2100, and meanwhile, the materials can move axially through the stirring surface 2213 with a certain oblique angle, so that the materials are uniformly mixed better. After the materials are mixed, the cylinder 5100 drives the connecting rod 5240 to move, so that the rotating shaft 5230 rotates, and the discharge door arc plate 5210 is moved away from the discharge opening, and the purpose of automatic discharging is achieved. After the discharge is completed, the cylinder 5100 performs a reverse action, so that the discharge gate arc plate 5210 covers the discharge opening. During the material stirring, the discharge gate arc 5210 is bearing the gravity of material, and because pivot 5230, connecting rod 5240 structure in this scheme for the gravity of material can't directly be transmitted for cylinder 5100 piston rod, thereby avoid cylinder 5100 piston rod to receive reverse effort, lead to the discharge opening to leak. Also, this configuration reduces the difficulty of opening and closing the discharge gate arc 5210.
As will be understood from fig. 4, in order to prevent the piston rod in the cylinder 5100 from being displaced too much, which may result in incomplete closing of the leakage opening, the outer end of the discharge opening is provided with a baffle 1200, the baffle 1200 is provided with a gasket 1300, and the discharge door arc plate 5210 presses the gasket 1300 when the discharge opening is closed. That is, when the discharge gate arc 5210 is blocked by the gasket 1300, the piston rod stops moving, and the discharge opening is completely closed. In other embodiments, a contact sensor can be mounted at the gasket 1300 for detecting the leak port closure state to avoid incomplete leak port closure in the event of a failure of the cylinder 5100.
In order to ensure that materials such as materials and water cannot leak from the discharge opening in the process of stirring the materials, and therefore ensure that the proportion of each material meets the requirements of regulations, as shown in fig. 4, in the present scheme, an annular sealing gasket 1400 is arranged around the outer side of the discharge opening, the rotating shaft 5230 is a camshaft, a first limiting block 5231 and a second limiting block 5232 are arranged on the camshaft, a limiting groove 5222 is arranged inside the connecting hole 5221, the first limiting block 5231 and the second limiting block 5232 are positioned in the limiting groove 5222, the discharge opening can be opened when the first limiting block 5231 abuts against one side wall of the limiting groove 5222, a spring 5260 is pressed between the second limiting block 5232 and the other side wall of the limiting groove 5222, and the discharge opening can be closed when the second limiting block 5232 is pressed against the limiting groove 5222. When the discharge opening is closed, the outer circumferential surface of the longer diameter of the cam shaft presses the connection hole 5221 upward, and the discharge gate arc plate 5210 presses the annular seal 1400.
When it is required to close the discharge opening, the second stopper 5232 is rotated in a direction in which the spring 5260 is pressed, and the discharge gate arc plate 5210 and the discharge gate side plate 5220 are rotated in a direction in which the cam shaft is rotated by the force of the spring 5260. When the discharge gate arc 5210 abuts against the gasket 1300, the discharge gate arc 5210 cannot rotate continuously, and the spring 5260 still has a certain compression space, so that the cam shaft can rotate continuously for a certain angle. In the process of the continuous rotation of the camshaft, the connecting position between the camshaft and the connecting hole 5221 gradually rotates from the short diameter to the long diameter, so that the discharge door arc plate 5210 moves towards the direction of pressing the annular sealing gasket 1400, and the annular sealing gasket 1400 is hermetically connected with the discharge door arc plate 5210, thereby avoiding the leakage of materials. When it is desired to open the discharge opening, the cam shaft is first rotated in the direction of the release spring 5260, and the annular seal 1400 is not rotated. When the cam shaft rotates a certain angle, the first stopper 5231 abuts against the side wall of the stopper groove 5222, so as to drive the discharge gate arc plate 5210 and the discharge gate side plate 5220 to rotate synchronously, thereby opening the discharge opening. By utilizing the structure, the phenomenon that the service life of the annular sealing gasket 1400 is short due to the fact that the discharge door arc plate 5210 generates large friction with the annular sealing gasket 1400 when being opened or closed can be avoided, and the discharge door arc plate 5210 can be tightly pressed on the annular sealing gasket 1400 when closing the discharge opening, so that the sealing effect is ensured.
In this embodiment, the seven blades 2210 include 6 adjacent forward blades 2211 and 1 reverse blade 2212, the forward blades 2211 and the reverse blades 2212 are opposite in axial direction of the stirring shaft 2100, the rotation direction of the stirring shaft 2100 is the same as the direction of the forward blades 2211 along the radial direction of the stirring shaft 2100, the adjacent blade assemblies 2200 are 60 degrees apart from the stirring shaft 2100, and the rotation direction of the forward blade 2211 adjacent to the reverse blade 2212 to the farthest forward blade 2211 is the same as the rotation direction of the stirring shaft 2100. The two stirring shafts 2100 are arranged in opposite directions. When the reverse blade 2212 in the left stirring shaft 2100 is close to the right stirring shaft 2100 and is located 30 degrees below the horizontal position, the reverse blade 2212 in the right stirring shaft 2100 is far from the left stirring shaft 2100 and is located in the horizontal position.
As shown in fig. 5, the forward blades 2211 on one mixer shaft 2100 push the mixture axially in one direction and the forward blades 2211 on the other mixer shaft 2100 push the mixture axially in the other opposite direction. The tail ends of the two stirring shafts 2100 are provided with a reverse blade 2212 for scraping the mixed materials away from the end part of the barrel body 1000, and the mixed materials are conveyed from one stirring shaft to the other stirring shaft, so that the materials complete large-cycle motion, and the stirring effect is good. In addition, in this scheme, the layout of blades 2210 on the stirring shaft 2100 is in a positive arrangement, that is: the blades 2210 are aligned in the same phase direction as the rotation direction of the stirring shaft 2100 when viewed against the direction of the mixed material. When the blades 2210 are arranged in the forward direction, when one blade 2210 pushes and stirs the mixed material forward, the former blade 2210 which can be coaxial through 60 degrees is only needed to push and stir continuously, so that the stirring efficiency is improved.
The phase relation of the blades 2210 on the two stirring shafts 2100 in the embodiment can ensure that the stirrer has high-efficiency stirring efficiency. As shown in FIG. 6, blades 2210 on left mixer shaft 2100 push the material outward, labeled I1-I7, where I1 is a counter-blade 2212; blades 2210 on the right stirring shaft 2100 push the material inward, labeled as II 1-II 7, where II 7 is a counter blade 2212; during the process that the two stirring shafts 2100 rotate for one circle, the countercurrent between the two stirring shafts 2100 is as follows: I7-II 6 and I4-II 3, the phase difference is 90 degrees; the phases of I2-II 1 are different by 210 degrees, the phases of I6-II 5 and I3-II 2 are different by 330 degrees. The two stirring shafts 2100 complete the same number of large cycles, the reverse flow phase of the first two times in each large cycle is small, the action is violent, the uniform stirring of mixed materials is facilitated, and the stirring quality is good.
When the mixer stopped using, in order to avoid the concrete to solidify in staving 1000, need with the interior sanitization of staving 1000, in this scheme, the top of staving 1000 has stirring cover 6000, has rivers pipeline (not shown in the figure) in the stirring cover 6000, and the inboard of stirring cover 6000 is opened has a plurality of water spouts (not shown in the figure) that are linked together with the rivers pipeline, and the water spout is towards stirring chamber 1100. Namely: if the barrel body 1000 needs to be cleaned, the water spray nozzle can be opened and the mixer can be started, so that clean water is stirred in the barrel body 1000, and the concrete on the inner wall is cleaned.
In this embodiment, there are two sets of driving assemblies 4000, and the same end of each of the two stirring shafts 2100 has a sprocket 3100. One of the two sets of driving assemblies 4000 is standby, so that the stirrer cannot work when one set of driving assemblies fails.
In addition, the drive assembly 4000 includes a motor 4100 and a speed reducer 4200, and the motor 4100 is connected to the speed reducer 4200 through a coupling.
Considering the influence of the size of the gap between blade 2210 and the inner wall of barrel 1000 on the service life of blade 2210 and the energy consumption for stirring, as shown in fig. 7, in the present embodiment, the outer end surface of blade 2210 is an arc-shaped surface, and the distance from the inner wall of barrel 1000 to the surface located at the front end in the arc-shaped surface is smaller than the distance from the inner wall of barrel 1000 to the surface located at the rear end in the rotation direction of stirring shaft 2100. The front end gap of the first contact mixed material is smaller than the rear end gap, which is beneficial to the release of the material once being clamped.
In order to keep the mixture as much as possible agitated by blades 2210, the arcuate surface is spaced less than 4mm from the inner wall of barrel 1000 in this embodiment.
