[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Example 1

[0024] See also Figure 1-Figure 5 A device for preventing cracking of machine-made sand concrete for highway engineering projects includes a base 100, a water storage tank 200 is mounted on the top of the base 100, a roller 300 is mounted on the bottom of the base 100, a fixed pipe 400 is mounted on the side of the water storage tank 200, and a nozzle 500 is rotatably connected to the top of the fixed pipe 400. When the water pump on the top of the water storage tank 200 is activated, water can be sprayed on the concrete at a fixed point through the fixed pipe 400 and the nozzle 500;

[0025] An adjustment assembly 600 is provided at the top of the base 100. This adjustment assembly 600 includes an adjustment gear 1 606. A power rod 601 is connected to the side of the roller 300. When the base 100 is pushed, the roller 300 rotates, which in turn drives the power rod 601, which is connected to it, to rotate. A bevel gear 1 602 is fixedly connected to the side of the power rod 601. When the power rod 601 rotates, it drives the bevel gear 1 602, which is fixed to it, to rotate. A transmission rod 603 is rotatably connected to the base 100. A bevel gear 2 604 is fixedly connected to the bottom of the transmission rod 603. Bevel gear 2 604 is located on the side of bevel gear 1 602 and is meshed with bevel gear 1 602. When bevel gear 1 602 rotates, it drives the meshed bevel gear 2 604 to rotate, causing bevel gear 2 604 to drive the transmission rod 603, which is fixed to it, to rotate. The outer side of the transmission rod 603 is fixedly connected to gear 2 605, and the adjustment gear 1 606 is sleeved on the outer side of the nozzle 500. When the adjustment component 600 is not enabled, the adjustment gear 1 606 does not engage with gear 2 605. The outer side of the nozzle 500 is fixedly connected to a force block 607. When rotation spraying is required, the adjusting gear 1 606 is pulled upward and rotated to a certain angle, and then the adjusting gear 1 606 is moved downward so that the adjusting gear 1 606 moves from one slot on the force block 607 to another slot. At this time, the adjusting gear 1 606 changes from a state of not engaging with gear 2 605 to engaging with gear 2 605. The transmission rod 603 drives the gear 2 605 fixedly connected to it to rotate, so that the gear 2 605 drives the adjusting gear 1 606 that is now engaged with it to rotate, and the adjusting gear 1 606 then squeezes the force block 607, so that the force block 607 drives the nozzle 500 fixedly connected to it to rotate, and performs rotational water spraying, so that the device can switch between rotational spraying and fixed-point spraying, thereby improving the usability of the device.

[0026] When in use, start the water pump on the top of the water storage tank 200, and then spray water on the concrete at a fixed point through the fixed pipe 400 and the nozzle 500; when it is necessary to rotate and spray, pull the adjusting gear 1 606 upwards, rotate it to a certain angle, and then move the adjusting gear 1 606 downwards, so that the adjusting gear 1 606 moves from one slot on the force block 607 to another slot. At this time, the adjusting gear 1 606 changes from a state of not meshing with the gear 2 605 to a state of meshing with the gear 2 605, and then pushes the base 100 to drive the roller 300 to rotate, and the roller 300 then drives The power rod 601 connected to it for transmission rotates, so that the power rod 601 drives the bevel gear 1 602 fixedly connected to it to rotate, and the bevel gear 1 602 drives the bevel gear 2 604 meshing with it to rotate, so that the bevel gear 2 604 drives the transmission rod 603 fixedly connected to it to rotate, and the transmission rod 603 drives the gear 2 605 fixedly connected to it to rotate, so that the gear 2 605 drives the adjusting gear 1 606 meshing with it at this time to rotate, and the adjusting gear 1 606 immediately squeezes the force block 607, so that the force block 607 drives the nozzle 500 fixedly connected to it to rotate, and performs rotational water spraying. Example 2

[0027] See also Figure 1-Figure 5 Based on the first embodiment, a stirring assembly 700 is provided within the water storage tank 200. The stirring assembly 700 includes a rotating rod 701 that extends through the water storage tank 200 and is rotationally connected to the water storage tank 200. A conveyor belt 702 is mounted on the outside of the transmission rod 603. The conveyor belt 702 is located outside the rotating rod 701 at one end away from the transmission rod 603. When the transmission rod 603 rotates, the conveyor belt 702 mounted on its outside causes the rotating rod 701, which is connected to the transmission rod 603 via the conveyor belt 702, to begin rotating. A stirring rod 703 is fixedly connected to the outside of the rotating rod 701. When the rotating rod 701 begins to rotate, it drives the stirring rod 703 fixedly connected to it to rotate, stirring the coolant in the water storage tank 200 and preventing it from settling due to static conditions. This improves the cooling efficiency of the device and makes the device easier to use.

[0028] During use, based on Example 1, when the transmission rod 603 rotates, it cooperates with the conveyor belt 702 installed on its outside, so that the rotating rod 701 connected to the transmission rod 603 through the conveyor belt 702 starts to rotate, and the rotating rod 701 then drives the stirring rod 703 fixedly connected to it to rotate, so as to stir the coolant in the water tank 200 to prevent it from settling due to standing still.

[0029] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
