AI Technical Summary
In existing construction grouting equipment, the spray nozzle is prone to shaking during the grouting process, making it difficult to ensure the uniformity and stability of the grouting. In particular, manual support is uncomfortable at different grouting heights, causing the spray to deviate from the target position.
The spray head adjustment mechanism includes components such as a lead screw, a sliding seat, a cylinder, and an extrusion plate. The position and fixation of the spray head are controlled by a motor-driven lead screw and cylinder. The toothed groove and the toothed protrusion on the top of the spray head increase the friction and prevent shaking.
It achieves stable fixation and uniform spraying at different grouting heights, improving the stability and uniformity of grouting and reducing the discomfort of manual operation.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of construction equipment, and in particular to a grouting device for construction. Background Technology
[0002] According to the patent document with publication number CN221031501U, the patent document describes a process where grouting materials are fed into a mixing tank through an inlet. A servo motor is activated to drive the mixing blades to rotate synchronously, thereby mixing the grouting materials inside the mixing tank to make them more uniform during use. A grout pump is activated in conjunction with a grout extraction pipe to extract the mixed grouting materials from the mixing tank. The mixed grouting materials are then sprayed onto the area to be grouted through a grout outlet pipe and a spray nozzle. The spray nozzle is turned on and off by a spray nozzle switch, and hand guards are used to prevent grout from splashing, thus protecting the hands of the workers.
[0003] The patent document states that during the grouting process, workers need to insert the grout nozzle into the grout inlet and then manually hold the nozzle to perform grouting. The grout entering the inlet will generate a reaction force that pushes the nozzle to shake. Furthermore, the grouting height varies during construction; if it is too high or too low, it will cause discomfort for manual holding, leading to the nozzle moving or deviating from the target position during spraying, making it difficult to ensure the uniformity of grouting.

[0029] The present invention will be further described below with reference to the accompanying drawings:
[0030] like Figures 1-11 As shown, a grouting device for building construction includes a base 1, a pusher 3 fixed on one side of the base 1, a mixing mechanism 4 on the top of the base 1, four casters 2 fixed at the bottom of the base 1, and a grouting head adjustment mechanism 5.
[0031] In this embodiment: the stirring mechanism 4 includes a stirring cylinder 401, which is fixed to the top of the base 1. A sealing cover 402 is provided on the top of the stirring cylinder 401. A stirring rod 403 is rotatably connected inside the stirring cylinder 401. Four bolt assemblies, including bolts and nuts, are threadedly connected between the stirring cylinder 401 and the sealing cover 402. Five sets of stirring blades are fixed to the outside of the stirring rod 403. Scrapers are fixed to both sides of the stirring blades near the cylinder wall of the stirring cylinder 401. A first motor 404 is fixedly installed at the input end of the stirring rod 403. An air inlet pipe 405 is connected to the top of the sealing cover 402, and an air compressor 406 is connected to the input end of the air inlet pipe 405. On the other side, there is a discharge pipe 408. The air inlet pipe 405 and the end of the discharge pipe 408 near the mixing drum 401 are equipped with a valve 407. The discharge end of the discharge pipe 408 is connected to the spray head 508. The sealing cover 402 is fixed to the top of the mixing drum 401 by bolts and nuts. The first motor 404 drives the stirring rod 403 to rotate, so as to stir the raw materials evenly and scrape the raw materials on the inner wall of the mixing drum 401. The air compressor 406 inputs compressed air into the mixing drum 401 through the air inlet pipe 405 to increase the pressure in the mixing drum 401, so as to make the slurry spray out from the discharge pipe 408. The pressure in the grouting drum and the flow of slurry are controlled by two valves 407 respectively.
[0032] In this embodiment: the spray head adjustment mechanism 5 includes a lead screw 501, which is rotatably connected to the top of the base 1. A second motor 502 is fixedly installed at the input end of the lead screw 501. A first sliding seat 503 is threadedly connected to the outer side of the lead screw 501. Guide posts 504 are provided on both sides of the lead screw 501, and the guide posts 504 pass through one side of the second sliding seat 505. The second sliding seat 505 is slidably connected to the top of the first sliding seat 503. A cylinder 506 is fixedly installed on one side of the second sliding seat 505. A spray head 508 is provided above the second sliding seat 505. A fixing plate 507 is provided on the outer side of the spray head 508. An extrusion plate 511 is slidably connected to the top of the fixing plate 507. A screw 509 is provided on one side of the extrusion plate 511. A fixing ring 510 is fixed to the outer side of the screw 509. The fixing plate 507 is fixed to the top of the second sliding seat 505. The screw 509 is threadedly connected to the fixing plate 507. 1. A square groove for placing the fixing ring 510 is provided on the other side. A toothed groove is provided at the bottom of the extrusion plate 511. A toothed protrusion that mates with the toothed groove is provided at the top of the spray head 508. The first sliding seat 503 is moved vertically by the rotation of the lead screw 501 driven by the second motor 502. The first sliding seat 503 is prevented from rotating and shaking during the movement by the two guide pillars 504. The extension and retraction of the second sliding seat 505 is driven by the extension and retraction of the cylinder 506. The position of the spray head 508 is restricted by inserting it into the fixing plate 507. The fixing ring 510 is moved up and down by rotating the screw 509, which in turn moves the extrusion plate 511 up and down, thereby realizing the extrusion and release of the spray head 508 by the extrusion plate 511. The toothed groove on the extrusion plate 511 and the toothed protrusion at the top of the spray head 508 cooperate to increase the friction and prevent shaking.
[0033] Working principle: Before grouting, the raw materials are poured into the mixing drum 401. The sealing cover 402 is fixed to the top of the mixing drum 401 with bolts and nuts. The first motor 404 is started to drive the mixing rod 403 to rotate and mix the raw materials evenly. After the raw materials are mixed, the spray nozzle 508 is inserted into the fixing plate 507. The screw 509 is rotated to drive the fixing ring 510 to move downward, which in turn drives the extrusion plate 511 to move downward, thereby achieving the extrusion plate 511 to extrude the spray nozzle 508. The toothed groove on the extrusion plate 511 cooperates with the toothed protrusion on the top of the spray nozzle 508 to increase friction and prevent shaking. After the spray nozzle 508 is fixed, the pusher 3 is pushed to drive the universal wheel 2 and the base 1 to the grouting area and the stop plate of the universal wheel 2 is stepped on to prevent movement. The second motor 502 is started to drive the screw 501 to rotate, so that the first sliding seat 503 moves in the vertical direction, thereby driving the spray nozzle 508 to move. When the cylinder 506 moves to the slurry inlet, it pushes the second sliding seat 505 to drive the spray nozzle 508 to extend and insert into the slurry inlet. The air compressor 406 is started to input compressed air into the mixing drum 401 through the air inlet pipe 405 to increase the pressure inside the mixing drum 401. This causes the slurry to be sprayed out from the discharge pipe 408 and enter the slurry inlet through the spray nozzle 508 to begin grouting. As the amount of slurry in the mixing drum 401 decreases, the mixing rod 403 continues to stir. The mixing blades ensure the uniformity of the slurry, while the scraper scrapes off the slurry on the inner wall of the mixing drum 401 to prevent slurry residue from being difficult to clean. After grouting is completed, the cylinder 506 pulls the second sliding seat 505 to drive the spray nozzle 508 out of the slurry inlet. The screw 509 is rotated to drive the fixing ring 510 to move upward, which in turn drives the extrusion plate 511 to move upward, thereby releasing the spray nozzle 508 from the extrusion plate 511. The spray nozzle 508 is then removed to complete the subsequent cleaning.
[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
