[0048] For further understanding of the present application, the application will be described in detail with reference to the drawings and embodiments. It should be understood that the embodiments are only to explain the application and not to limit the application.

[0049] The following will be described in detail with reference to the drawings and embodiments Figures 1-6 The present embodiment will be further described in detail.

[0050] As shown in the drawings, the concrete mixing device capable of automatically controlling the mixing time in the present embodiment comprises, Figure 1

[0051] The mixing tank 100 has an open upper end and is used for containing concrete.

[0052] The mixing assembly is arranged in the mixing tank 100 and is used for mixing and stirring the concrete.

[0053] The lifting assembly is arranged on the upper end surface of the mixing tank 100 and is used for lifting and adjusting the mixing assembly.

[0054] The water supply assembly is arranged on the inner wall of the opening of the mixing tank 100 and is used for cleaning the inner wall of the mixing tank 100.

[0055] The protection assembly is arranged at the opening of the mixing tank 100 and is used for protecting the water supply assembly.

[0056] The protection assembly comprises a shielding plate 130 and a driving member. The shielding plate 130 is used for shielding the water supply assembly. The driving member is arranged on the outer side wall of the mixing tank 100 and is used for driving the shielding plate 130 to lift and lower.

[0057] The control assembly is arranged on the lifting assembly and is used for controlling the mixing time of the mixing assembly for the concrete.

[0058] ​In this embodiment, cement, water, sand, gravel, and admixtures are added into the mixing tank 100 through the upper opening. The mixing component is controlled by the control component to operate for a certain period of time, so that the mixing component can mix and stir the cement, water, sand, gravel, and admixtures to form concrete. When the mixing component is mixing the concrete, the lifting component can drive the mixing component to adjust its height, so that the mixing component can mix the concrete at different heights in the mixing tank 100, thereby reducing the blind zone of the mixing component and thus improving the mixing effect of the concrete in the mixing tank 100.

[0059] A discharge pipe 510 is installed on the outer wall of the mixing tank 100 at the bottom end. A plug 520 is installed on the external thread of the discharge pipe 510. After the mixing component completes its operation for a certain period of time, the control component will drive the mixing component to stop operating. At this time, the concrete in the mixing tank 100 is mixed. Then, the plug 520 is removed from the discharge pipe 510, so that the concrete can be discharged from the mixing tank 100 through the discharge pipe 510. When the concrete is mixed in the mixing tank 100, the plug 520 closes the discharge pipe 510.

[0060] When the concrete is discharged through the discharge pipe 510, water can be supplied to the mixing tank 100 through the water supply component, which makes it convenient for workers to clean the inner wall of the mixing tank 100 and facilitates actual use.

[0061] In order to prevent concrete from splashing and adhering to the water supply component when the mixing component is mixing the concrete, thereby affecting the next use of the water supply component, when the mixing component is mixing the concrete, the driving component can drive the shield 130 to move down, so that the shield 130 can shield the water supply component, thereby preventing concrete from splashing and adhering to the water supply component.

[0062] In actual use, multiple support legs 150 are fixedly installed on the lower end face of the mixing tank 100 along its circumference, and the mixing tank 100 can be placed in the corresponding position through the support legs 150.

[0063] like Figures 1-5 As shown, in this embodiment, the stirring assembly includes a rotating rod 200, a sleeve 210, and a stirring element disposed on the outer wall of the sleeve 210.

[0064] The rotating rod 200 is rotatably mounted inside the mixing tank 100;

[0065] The sleeve 210 is vertically mounted on the upper end of the rotating rod 200 and is used to drive the stirring component to stir as the rotating rod 200 rotates.

[0066] The lifting assembly includes a mounting plate 110, and the upper end of the sleeve 210 is rotatably connected to the mounting plate 110.

[0067] In this embodiment, by setting up the rotating rod 200, sleeve 210, mixing component and mounting plate 110, when the rotating rod 200 rotates, the rotating rod 200 can drive the sleeve 210 to rotate, so that the mixing component on the sleeve 210 can mix and stir the concrete in the mixing tank 100.

[0068] In this device, a corresponding locking block 401 is fixedly installed at the upper end of the rotating rod 200 along its axial direction, and a corresponding locking groove 411 is fixedly installed inside the sleeve 210 for the corresponding locking block 401 to be engaged. Through the cooperation of the locking block 401 and the locking groove 411, the rotation of the rotating rod 200 can drive the sleeve 210 to rotate.

[0069] The lower end of the rotating rod 200 is rotatably mounted on the inner bottom wall of the mixing tank 100 via a bearing. A second motor 220 is fixedly mounted on the bottom wall of the mixing tank 100. The output shaft of the second motor 220 is fixedly connected to the rotating rod 200, so that the second motor 220 can drive the rotating rod 200 to rotate.

[0070] The upper end of the sleeve 210 is rotatably mounted on the mounting plate 110 via a bearing. When the mounting plate 110 is raised or lowered, the raising or lowering of the mounting plate 110 can drive the sleeve 210 to be raised or lowered, thereby allowing the mixing component to be raised or lowered. At this time, the mixing component can mix the concrete of different heights in the mixing tank 100.

[0071] The mixing component includes a fixing plate 211 fixedly disposed at the lower end of the sleeve 210. Fixing rods 212 are fixedly installed at both ends of the fixing plate 211. Multiple mixing rods 213 are fixedly installed on the fixing rods 212 along their height direction. The rotation of the sleeve 210 can drive the fixing rods 212 and the mixing rods 213 to rotate through the fixing plate 211, thereby realizing the mixing of concrete by the fixing rods 212 and the mixing rods 213.

[0072] In order to achieve the best stirring effect, the stirring rod 213 is set parallel to the fixing plate 211;

[0073] In actual use, after the concrete is discharged from the discharge pipe 510, a lot of concrete is likely to remain in the mixing tank 100. A scraper 500 is fixedly installed at the lower end of the rotating rod 200. The rotating rod 200 drives the scraper 500 to rotate around the circumference of the rotating rod 200, which can push the concrete remaining in the mixing tank 100 toward the discharge pipe 510, thereby reducing the amount of concrete remaining in the mixing tank 100.

[0074] like Figures 1-4As shown, in this embodiment, the lifting assembly further includes,

[0075] Threaded blocks 120 are disposed on the outer side wall of the mixing tank 100;

[0076] The threaded rod 112 is rotatably located at both ends of the mounting plate 110, and the thread passes through the corresponding threaded block 120.

[0077] A rotating component, located within the mounting plate 110, is used to drive the threaded rods 112 on both sides to rotate synchronously.

[0078] In this embodiment, the arrangement of the threaded block 120, threaded rod 112, and rotating component allows the upper ends of the two threaded rods 112 to be rotatably mounted on the mounting plate 110 via bearings, while the threaded block 120 is fixedly mounted on the outer wall of the mixing tank 100. When the rotating component drives the two threaded rods 112 to rotate synchronously, the two threaded rods 112 and the corresponding threaded block 120 engage with each other. At this time, the two threaded rods 112 can drive the mounting plate 110 to rise and fall. The rise and fall of the mounting plate 110 can drive the sleeve 210 to rise and fall along the rotating rod 200. The rise and fall of the sleeve 210 can adjust the rise and fall of the mixing rod 213 through the fixing plate 211 and the fixing rod 212. When the mixing rod 213 is adjusted, the rotating rod 200 will drive the mixing rod 213 to rotate. At this time, the rotation and rise and fall of the mixing rod 213 can mix the concrete between different height layers in the mixing tank 100, thereby improving the mixing effect of the concrete.

[0079] like Figures 1-3 As shown, in this embodiment, the rotating component includes,

[0080] The sprocket 310 is fixedly sleeved on the threaded rod 112 located inside the mounting plate 110;

[0081] Chain 311 is fitted onto the opposite sprocket 310;

[0082] The first motor 111 is fixedly mounted on the mounting plate 110 and is used to drive one of the two threaded rods 112 to rotate.

[0083] In this embodiment, the arrangement of sprocket 310, chain 311 and first motor 111 enables one of the two threaded rods 112 to rotate when the first motor 111 drives one of them to rotate, which in turn drives the corresponding sprocket 310 to rotate. The rotation of the sprocket 310, through the chain 311, drives the sprocket 310 on the other threaded rod 112 to rotate. That is, the two threaded rods 112 rotate synchronously, thereby adjusting the height of the mounting plate 110.

[0084] Specifically, the mounting plate 110 has a cavity, and the sprocket 310 and chain 311 are installed in the cavity;

[0085] In actual use, the control components also include a controller and a timer. The controller and timer are fixedly installed on the outer wall of the mixing tank 100. The timer, the second motor 220 and the controller are electrically connected. In use, the operator adjusts the timer to the set time value according to the required mixing time. At this time, the timer transmits a signal to the controller, and the controller controls the second motor 220 to work. When the timer reaches the set time value, the controller controls the second motor to stop working and controls the timer to return to zero, thereby realizing the control of the mixing time.

[0086] like Figures 1-6 As shown, in this embodiment, the water supply component includes,

[0087] Multiple nozzles 600 are distributed around the circumference of the mixing tank 100, and are connected via a water supply pipe 160.

[0088] The arc-shaped plate 610 is installed inside the mixing tank 100 and is used for installing the nozzle 600.

[0089] In this embodiment, by setting up the arc plate 610 and the nozzle 600, the two arc plates 610 are fixedly installed on the inner side wall of the mixing tank 100, and the multiple nozzles 600 are fixedly installed on the corresponding arc plates 610. The multiple nozzles 600 are connected by a water supply pipe 160. Water is supplied to the water supply pipe 160 by a water pump, and then water is supplied to the mixing tank 100 through the nozzles 600.

[0090] like Figures 1-6 As shown in this embodiment,

[0091] The baffle 130 includes baffles 130 disposed on both sides of the mounting plate 110, and one side of the baffle 130 is bent to form a bent portion 131.

[0092] The driving component includes an electric push rod 141, which is installed on the outer wall of the mixing tank 100 and is used to drive the corresponding baffle plate 130 to rise and fall.

[0093] In this embodiment, the bending part 131 and the electric push rod 141 are configured such that when the electric push rod 141 drives the baffle plate 130 to move upward, the upward movement of the baffle plate 130 can drive the bending part 131 to move upward. At this time, the bending part 131 releases the obstruction of the multiple nozzles 600, and the nozzles 600 can supply water into the mixing tank 100. When the electric push rod 141 drives the baffle plate 130 to move downward, the downward movement of the baffle plate 130 can drive the bending part 131 to move downward. At this time, the downward movement of the bending part 131 can obstruct the multiple nozzles 600, thereby achieving the protection of the multiple nozzles 600 by the bending part 131, thus preventing concrete from adhering to the nozzles 600 and affecting the subsequent use of the nozzles 600.

[0094] In actual use, a base plate 140 is fixedly installed on the side wall of the mixing tank 100 corresponding to the electric push rod 141. The lower end of the electric push rod 141 is fixedly installed on the base plate 140. The side wall of the baffle plate 130 extends outward to form a baffle part 132. The upper end of the electric push rod 141 is fixedly connected to the baffle part 132, so that the baffle plate 130 can be driven to rise and fall by the electric push rod 141. That is, the bending part 131 rises and falls to protect or remove the protection of multiple nozzles 600.

[0095] In practical use, cement, water, sand, and additives are added to the mixing tank 100. The operator then sets the timer to the desired mixing time. The timer transmits a signal to the controller, which in turn controls the second motor 220. This causes the rotating rod 200 to drive the fixed rod 212 and the mixing rod 213 to rotate via the sleeve 210 and the fixed plate 211. During the mixing process, the operator can start the first motor 111 as needed, which then drives the sprocket 310 and chain 311. This allows the two threaded rods 112 to adjust the height of the mounting plate 110 via the threaded block 120. The lifting and lowering of the mounting plate 110, through the sleeve 210, the fixing plate 211, and the fixing rod 212, can drive the stirring rod 213 to adjust its height, so that the concrete in the mixing tank 100 can be better mixed. After the concrete mixing is completed, the plug 520 is removed from the discharge pipe 510, and the concrete can be discharged from the discharge pipe 510. At the same time, the second motor 220 drives the rotating rod 200 to drive the scraper 500 to rotate, which can reduce the amount of concrete residue in the mixing tank 100.

[0096] In summary, the above description is only a preferred embodiment of the present utility model. All equivalent changes and modifications made within the scope of the patent application of the present utility model shall fall within the scope of the patent of the present utility model.
