[0030] Working principle description:

[0031] The basic function of this equipment is the same as that of the utility model patent named Spraying Dust Reduction Device for Concrete Preparation (Application No. 202222114756.1). The equipment performs spraying and dust reduction through the spray component 1, adjusts the equipment height through the telescopic rod 2, and achieves the effect of auxiliary support through the self-locking universal wheel 4; it is worth noting that when the equipment needs to be placed alone, first lock the self-locking universal wheel 4, push the first push rod 11, and the movement of the first push rod 11 drives the first limit block 10 to compress the first spring 9. At this time, the first limit block 10 disengages from the first limit hole 14 and retracts into the first slide groove 8. At this time, the support frame 13 can be pulled out around the rotating shaft 12. After the support frame 13 is pulled out, it contacts the second limit block 17. The second limit block 17 is forced to compress the second spring 16 and retract the second In the slide groove 15, when the second limit block 17 matches the second limit hole 19, the second limit block 17 pops out and is inserted into the second limit hole 19 under the rebound action of the second spring 16 to fix the support frame 13. At this time, the support frame 13 and the self-locking universal wheel 4 cooperate to enable the equipment to be placed independently; when it is necessary to retract the support frame 13, the second push rod 18 is pushed, and the second push rod 18 drives the second limit block 17 to compress the second spring 16. At this time, the second limit block 17 escapes from the second limit hole 19, and the support frame 13 is rotated to be retracted into the receiving groove 7. The support frame 13 contacts the first limit block 10 to compress the first spring 9. When the first limit block 10 matches the first limit hole 14, the first limit block 10 is inserted into the first limit hole 14 to fix the support frame 13.

[0032] Preferably, a rubber cushion is installed on the support frame 13. Such a structural design reduces the friction damage to the support frame 13 and makes the device placement more stable.

[0033] Preferably, the first push rod 11 is provided with anti-slip grooves. Such a structural design makes the first push rod 11 more convenient to operate.

[0034] Preferably, the second push rod 18 is provided with anti-skid grooves. Such a structural design makes the second push rod 18 more convenient to operate.

[0035] Preferably, a rubber cushion is installed in the storage groove 7. Such a structural design reduces the friction damage to the storage groove 7 and prolongs the service life of the equipment.

[0036] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the relevant technical field without departing from the spirit and technical ideas disclosed in the present invention shall still be covered by the claims of the present invention.
