[0012] 2. The earthwork construction mortar mixing device can detect the moving distance of the pull rod through the first distance sensor, and then control the driving of the electric telescopic rod through the controller, so that in the process of the pull rod compressing the spring through the fixed sleeve, it can generate a sufficiently large elastic force to drive the moving frame to move. At the same time, the moving distance of the moving frame can be detected by the second distance sensor to ensure that the first driven disk and the second driven disk can be closed under the elastic force of the spring. When the moving frame fails to drive the first driven disk and the second driven disk to close after the electric telescopic rod is driven, the alarm can be used to remind the operator to perform maintenance.

DETAILED DESCRIPTION

[0020] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant utility model, rather than to limit the utility model. It is also necessary to explain that, for ease of description, only the parts related to the utility model are shown in the accompanying drawings.

[0021] The accompanying drawings in the embodiments of the present invention: different types of section lines in the drawings are not marked according to national standards, nor do they impose any requirements on the materials of the components. Instead, they are used to distinguish the cross-sectional views of the components in the drawings.

[0022] See also Figure 1-5A mortar mixing device for earthwork construction includes a frame 1 and a first mixing drum 2, a second mixing drum 3 and a reduction motor 4 fixedly installed above the frame 1. The first mixing drum 2 and the second mixing drum 3 are rotatably connected with a first hollow mixing rod 5 and a second hollow mixing rod 6 respectively. One side of the second mixing drum 3 is rotatably connected with a driving shaft 8 sleeved inside the second hollow mixing rod 6 through a support 7. The outer side of one end of the driving shaft 8 extending outside the support 7 is fixedly sleeved with the output shaft of the reduction motor 4 through a shaft sleeve. The outer side of the driving shaft 8 is sleeved with a first hollow mixing rod 5 and a second hollow mixing rod 6. A transmission mechanism 9 is arranged on the outside of the second hollow stirring rod 6, and a controller 10 is fixedly installed on the outside of the frame 1, which is electrically connected to the reduction motor 4 and has an alarm device inside. A first fixing frame 11 and a second fixing frame 12 are fixedly installed on opposite sides of the first mixing drum 2 and the second mixing drum 3, respectively. A transposition mechanism 13 located below the transmission mechanism 9 is fixedly installed between the first fixing frame 11 and the second fixing frame 12, and a driving mechanism 14 is movably sleeved on the outside of the transposition mechanism 13 and fixedly installed on the outside of the second mixing drum 3.

[0023] The transmission mechanism 9 includes a first driven disk 91 and a second driven disk 92 which are respectively mounted on the outside of the first hollow stirring rod 5 and the second hollow stirring rod 6 and are rotatably connected to the outside of the driving shaft 8, and a driving disk 93 which is mounted on the outside of the driving shaft 8. The insides of the first driven disk 91 and the second driven disk 92 are respectively fixedly connected to the first hollow stirring rod 5 and the second hollow stirring rod 6 by bolts 94, and the opposite sides of the first driven disk 91 and the second driven disk 92 are provided with annular limiting grooves 95 which are equidistantly distributed. The end faces on both sides of the active disk 93 are provided with limiting bosses 96 which are equidistantly distributed in an annular shape and matched with the limiting grooves 95. The first driven disk 91 and the second driven disk 92 can be limited by bolts 94, and the two can be easily disassembled and assembled. The first driven disk 91 and the second driven disk 92 can support the driving shaft 8, so that when the active disk 93 is closed with the first driven disk 91 or the second driven disk 92, the driving force of the driving shaft 8 can be stably transmitted to the first hollow stirring rod 5 or the second hollow stirring rod 6.

[0024] Among them, the shifting mechanism 13 includes a fixed rod 131 fixedly mounted between the first fixed frame 11 and the second fixed frame 12, and a movable frame 132 is movably mounted on the outer side of the fixed rod 131. Two symmetrically distributed fixed columns 133 are arranged on the top of the movable frame 132, and bearings 134 are fixedly mounted on the outer sides of the two fixed columns 133. The bearings 134 ensure that the movable frame 132 will not affect the rotation of the active disk 93 during the movement, so that the device can switch the working state of the first hollow stirring rod 5 and the second hollow stirring rod 6 without stopping the machine.

[0025] Among them, the driving mechanism 14 includes a pull rod 141 movably sleeved inside the first fixed frame 11 and the second fixed frame 12 and movably sleeved inside the mobile frame 132, and an electric telescopic rod 142 fixedly installed on the outside of the second mixing drum 3 and electrically connected to the controller 10. The outer side of the pull rod 141 is movably sleeved with a fixed sleeve 143 and a spring 144 symmetrically distributed on both sides of the mobile frame 132. The inner fixed sleeve 143 is fixedly sleeved with a first fixed pin 145 movably sleeved inside the pull rod 141. The inner movably sleeved at one end of the electric telescopic rod 142 is a second fixed pin 146 fixedly sleeved inside one end of the pull rod 141. The spring 144 ensures that the pull rod 141 will not directly push the mobile frame 132 to move during the movement. Even if the limiting boss 96 is not stuck in the inner side of the limiting groove 95, the active disk 93 can use the elastic force of the spring 144 to clamp the limiting boss 96 into the inner side of the limiting groove 95 during the rotation, thereby ensuring that the power can be transmitted stably.

[0026] A baffle 15 is fixedly mounted on the outer side of one end of the pull rod 141 away from the second fixing pin 146 , and a first distance sensor 16 is fixedly mounted inside the first fixing frame 11 and electrically connected to the controller 10 on one side of the baffle 15 .

[0027] The second fixing frame 12 is internally fixed with a second distance sensor 17 which is electrically connected to the controller 10 .

[0028] A boss is provided on the inner side of the active disk 93 , and the boss can be used to limit the active disk 93 and enable the active disk 93 to move along the axial direction of the driving shaft 8 under the push of the moving frame 132 .

[0029] When the device is in use, the electric telescopic rod 142 and the deceleration motor 4 are controlled to start by the reduction motor 4. The pull rod 141 is driven by the electric telescopic rod 142 to move, and the movable frame 132 is driven to move by the compression spring 144. When the movable frame 132 moves, the active disk 93 is pushed to move along the axial direction of the drive shaft 8 through the bearing 134, and then the active disk 93 is closed with the first hollow stirring rod 5 or the second hollow stirring rod 6. The drive shaft 8 and the active disk 93 are driven by the reduction motor 4 to rotate. After the limiting boss 96 is stuck in the inner side of the limiting groove 95, the active disk 93 can drive the first hollow stirring rod 5 or the second hollow stirring rod 6 to rotate, and then the mortar raw materials inside the first mixing drum 2 and the second mixing drum 3 are stirred and mixed respectively by the first hollow stirring rod 5 and the second hollow stirring rod 6.
