[0032] See also Figure 1-Figure 3 An adjustment device 10 is fixedly installed on the top of the support frame 2 at a position behind the second cross beam 7 .

[0033] See also Figure 4-Figure 5The stirring device 5 includes a stirring drum 51 , and the operator adds cement and yellow sand into the interior of the stirring drum 51 through the front end opening of the stirring drum 51 .

[0034] See also Figure 2 and Figure 4-Figure 5 A connecting sleeve 52 is fixedly installed at the end of the stirring drum 51, and a transmission gear 53 is fixedly sleeved on the outer surface of the connecting sleeve 52 near the end. The transmission gear 53 is meshed with the driving gear 9. The interior of the connecting sleeve 52 is movably sleeved with the water supply device 6. A stirring blade 54 is fixedly installed on the inner wall of the stirring drum 51. The stirring blade 54 is distributed in a linear array along the axial direction of the stirring drum 51. When the stirring drum 51 rotates, the stirring blade 54 will stir the material inside the stirring drum 51.

[0035] See also Figure 4-Figure 5 A coupling seat 55 is fixedly installed on the outer surface of the stirring drum 51 near the front end. The coupling seats 55 are distributed in a circular array. A connecting rod 56 is fixedly installed at the front end of the coupling seat 55. A matching seat 57 is fixedly installed at one end of the connecting rod 56. A matching groove 58 is provided at the end of the matching seat 57.

[0036] See also Figure 4-Figure 5 The axis of the matching seat 57 and the axis of the stirring drum 51 are located on the same center line.

[0037] See also Figure 5-Figure 10 The water supply device 6 includes a water supply pipe 61, a limit ring 62 is provided on the outer surface of the water supply pipe 61 near the front end, the water supply pipe 61 is movably sleeved inside the connecting sleeve 52 through the cooperation effect of the limit ring 62, a connecting sleeve 63 is movably sleeved on the inner cavity of the water supply pipe 61 near the end, and a water injection pipe 64 is sleeved inside the connecting sleeve 63, and the water injection pipe 64 is connected to the water supply equipment. A rotating pipe 65 is fixedly installed at the front end of the water supply pipe 61, and a rotating plate 66 is fixedly installed on the outer surface of the rotating pipe 65. As the viscosity of the concrete inside the mixing drum 51 increases, the mixing blades 54 will drive the concrete to rotate synchronously after contacting with the concrete. In this process, the concrete also contacts the rotating plate 66 at the same time, and drives the rotating pipe 65 to rotate synchronously through the rotating plate 66 until the concrete cannot bear the weight of the rotating plate 66 and collapses from the gap between the mixing blades 54, and then the rotating plate 66 is reset. As the mixing proceeds, the viscosity of the concrete continues to increase, and the angle of rotation of the rotating pipe 65 driven by the rotating plate 66 also continues to increase.

[0038] See also Figure 6-Figure 10The rotating plates 66 are distributed in a linear array along the axial direction of the rotating tube 65. A drainage pipe 67 is provided on the outer surface of the rotating tube 65 between the rotating plates 66. The water supply device sends water into the interior of the water supply pipe 61 through the water injection pipe 64, and then enters the interior of the mixing drum 51 through the drainage pipe 67.

[0039] In the process of mixing concrete, the traditional method is to add cement, yellow sand and water into the mixing drum 51 and mix them. This method of adding water at one time will cause the final concrete strength to decrease and is only suitable for engineering operations that do not require high concrete quality. The equipment involved in this application document, the water supply equipment, will send water into the water supply pipe 61 through the water injection pipe 64, and flow out from the inside of the drainage pipe 67 and enter the inside of the mixing drum 51, so that water can be gradually added to the inside of the mixing drum 51 at a certain flow rate and mixed with cement, yellow sand and other materials, achieving the effect of adding water in batches, making the final concrete structure stronger, and no manual addition is required during the whole process, reducing the difficulty of use. In addition, since there are a large number of drainage pipes 67 and they are distributed on the outer surface of the rotating tube 65 in a linear array, water can enter the inside of the mixing drum 51 in a dispersed form through multiple drainage pipes 67, so that water can better contact with the internal materials of the mixing drum 51, which can effectively shorten the time required for mixing and improve production efficiency.

[0040] See also Figure 6-Figure 10 A trigger device 68 is movably installed inside the rotating plate 66, and an annular plate 69 is provided inside the rotating plate 66 at a position in front of the trigger device 68. The front and rear sides of the annular plate 69 are respectively clamped with a front spring 601 and a rear spring 602, and the front end of the front spring 601 is clamped with a matching block 603, and the end of the rear spring 602 is clamped with the front end of the trigger device 68. A transverse sliding groove 604 is provided on the outer surface of the water supply pipe 61 at a position behind the limiting ring 62, and a clamping groove 605 is provided on the top of the inner wall of the transverse sliding groove 604 near the end.

[0041] See also Figure 5-Figure 6 , the front end of the rotating plate 66 and the stirring blade 54 are in a staggered state.

[0042] See also Figure 5 and Fig.10 Under the action of pressure, the matching block 603 will extend from the front end of the rotating tube 65 and engage with the matching groove 58.

[0043] See also Fig.10 , the rear spring 602 is in a compressed state in the initial state.

[0044] When the trigger rod 685 is unfastened from the engaging groove 605, since the drain pipe 67 is blocked and the water supply device is still supplying water to the inside of the water supply pipe 61, the water pressure inside the rotating tube 65 is continuously increased, thereby pushing the matching block 603 to extend from the front end of the rotating tube 65 and match with the matching groove 58. Since the stirring drum 51 drives the matching seat 57 and the matching groove 58 to always be in a rotating state, after the matching block 603 matches with the matching groove 58, the rotating tube 65 rotates synchronously with the stirring drum 51, so that after the device completes the water addition, the rotating plate 66 can participate in the stirring operation, thereby improving the stirring efficiency and further improving the practicality of the device.

[0045] See also Figure 6-Figure 10 The trigger device 68 includes a trigger shaft 681, and the trigger shaft 681 rotates synchronously with the water supply pipe 61.

[0046] See also Figure 11-Figure 12 A baffle 682 is provided on the outer surface of the trigger shaft 681, a liquid guide hole 683 is opened at a position between the baffles 682 on the outer surface of the trigger shaft 681, a water retaining tail plate 684 is fixedly installed at a position near the end of the outer surface of the trigger shaft 681, and a trigger rod 685 is fixedly installed at a position on the outer surface of the trigger shaft 681 in front of the water retaining tail plate 684.

[0047] See also Figure 7 and Figure 10-12 In the initial state, the liquid guide hole 683 corresponds to the drain pipe 67. After the elastic force of the rear spring 602 is released, the rotating shaft 681 is triggered to move forward and the baffle 682 blocks the drain pipe 67.

[0048] See also Figure 6 and Fig.11 The outer surface of the water retaining tail plate 684 and the interior of the water supply pipe 61 are sealed.

[0049] See also Figure 1 , Figure 6 and Figure 11-Figure 12 In the initial state, the trigger rod 685 extends from the inside of the horizontal slide groove 604 and is engaged with the engaging groove 605. When the trigger shaft 681 rotates a certain angle, the trigger rod 685 will come into contact with the adjustment device 10, so that the trigger rod 685 is disengaged from the engaging groove 605.

[0050] During the rotation of the mixing drum 51, the mixing blades 54 can stir the material inside the mixing drum 51. As the mixing progresses, the viscosity of the material continues to increase, so that after the material moves to a certain height along with the mixing blades 54, under the action of gravity and the pushing of the rotating plate 66, it will collapse from the gap between the mixing blades 54 to the bottom of the inner cavity of the mixing drum 51. In this process, the strength of the material itself will drive the rotating plate 66 to rotate a certain angle, and as the viscosity of the concrete increases, the angle of rotation of the rotating plate 66 continues to increase, and finally the trigger rod 68 5 is rotated to contact with the adjustment device 10, under which the trigger rod 685 is disengaged from the engaging state with the engaging groove 605, and the elastic force stored in the rear spring 602 is released, thereby driving the trigger device 68 as a whole to move in the direction close to the front end of the rotating tube 65, so that the baffle 682 blocks the drain pipe 67, achieving the effect of automatic lifting and water injection, thereby improving the automation of the device. At the same time, compared with the manual water adding method, the effect of this automatic control of stopping water injection can accurately control the water content of the concrete finally obtained in the mixing drum 51, thereby improving the practicality of the device.

[0051] See also Figure 6 and Fig.13 The adjustment device 10 includes a third cross beam 101, a limiting sleeve 102 is arranged on the top of the third cross beam 101, the limiting sleeve 102 is sleeved with the water supply pipe 61, a connecting plate 103 is fixedly installed on the top of the outer surface of the limiting sleeve 102, a mounting side plate 104 is fixedly installed on the top of the connecting plate 103 near the front side, an arc hole 105 is opened on one side of the mounting side plate 104, and a trigger block 106 is fixedly installed on the top of the connecting plate 103 near the mounting side plate 104 by bolt connection.

[0052] See also Figure 1 , Fig.11 and Fig.13 When the water supply device 6 as a whole rotates, the trigger rod 685 will come into contact with the trigger block 106 .

[0053] By releasing the bolts connecting the trigger block 106, the position of the trigger block 106 is adjusted. When the position of the trigger block 106 is adjusted clockwise, the water supply pipe 61 rotates a smaller angle to make the trigger rod 685 contact with the trigger block 106 and release the state of the trigger rod 685 being engaged with the engaging groove 605. At this time, the water content of the material inside the mixing drum 51 is low, and the fluidity and viscosity are reduced. When the position of the trigger block 106 is adjusted counterclockwise, the water supply pipe 61 rotates a larger angle to make the trigger rod 685 contact with the trigger block 106 and release the state of the trigger rod 685 being engaged with the engaging groove 605. At this time, the water content of the material inside the mixing drum 51 is high, and the fluidity and viscosity are high, so that the operator can control the fluidity and viscosity of the final concrete by adjusting the trigger block 106, thereby further improving the practicality of the device.

[0054] The method of use of the present invention is as follows: During use, the operator adds cement and yellow sand into the mixing drum 51, then starts the power machine 8 to drive the driving gear 9 and drive the mixing device 5 to rotate, and the water supply equipment will send water into the water supply pipe 61 through the water injection pipe 64, and the water flows out from the inside of the drainage pipe 67 and enters the mixing drum 51, so that water can be gradually added to the mixing drum 51 at a certain flow rate and mixed with cement, yellow sand and other materials, achieving the effect of adding water in batches, making the final concrete structure stronger, and no manual addition is required during the whole process, which reduces the difficulty of use. In addition, since the number of drainage pipes 67 is large and they are distributed on the outer surface of the rotating pipe 65 in a linear array, water can flow through multiple drainage pipes 67. The drainage pipes 67 enter the interior of the mixing drum 51 in a dispersed manner, so that water can better contact the internal materials of the mixing drum 51, which can effectively shorten the time required for mixing. During the rotation of the mixing drum 51, the mixing blades 54 can stir the materials inside the mixing drum 51. As the mixing progresses, the viscosity of the materials continues to increase, so that after the materials move to a certain height with the mixing blades 54, under the action of gravity and the pushing of the rotating plate 66, they will collapse from the gaps between the mixing blades 54 to the bottom of the inner cavity of the mixing drum 51. In this process, the strength of the material itself will drive the rotating plate 66 to rotate a certain angle, and as the viscosity of the concrete increases, the angle of rotation of the rotating plate 66 continues to increase. Finally, the trigger rod 685 is rotated to contact with the adjustment device 10. Under this action, the trigger rod 685 is disengaged from the engaging state with the engaging groove 605. At this time, the elastic force stored in the rear spring 602 is released, thereby driving the trigger device 68 as a whole to move in the direction close to the front end of the rotating tube 65, so that the baffle 682 blocks the drain pipe 67, and the effect of automatic lifting to water injection is achieved. At the same time, compared with the manual water adding method, this automatic control of stopping water injection can accurately control the water content of the concrete finally obtained inside the mixing drum 51. By releasing the bolts connecting the trigger block 106, the position of the trigger block 106 is adjusted. When the position of the trigger block 106 is adjusted clockwise, the water supply pipe 61 can be rotated by a smaller angle to make The trigger rod 685 contacts the trigger block 106 and releases the state of the trigger rod 685 being engaged with the engaging groove 605. At this time, the water content of the material inside the mixing drum 51 is low, and the fluidity and viscosity are reduced. When the position of the trigger block 106 is adjusted counterclockwise, the water supply pipe 61 rotates at a larger angle to make the trigger rod 685 contact the trigger block 106 and release the state of the trigger rod 685 being engaged with the engaging groove 605. At this time, the water content of the material inside the mixing drum 51 is high, and the fluidity and viscosity are high, so that the operator can control the fluidity and viscosity of the final concrete by adjusting the trigger block 106. When the trigger rod 685 is released from the engaging groove 605, since the drain pipe 67 is blocked,The water supply device is still supplying water to the inside of the water supply pipe 61, so that the water pressure inside the rotating pipe 65 is continuously increased, thereby pushing the matching block 603 to extend from the front end of the rotating pipe 65 and match with the matching groove 58. Since the stirring drum 51 drives the matching seat 57 and the matching groove 58 to always be in a rotating state, after the matching block 603 matches with the matching groove 58, the rotating pipe 65 and the stirring drum 51 rotate synchronously, so that after the device completes the water addition, the rotating plate 66 can participate in the stirring operation, thereby improving the stirring efficiency.
