A gypsum mortar laying device

Abstract

This application discloses a gypsum mortar laying device, relating to the field of gypsum mortar laying. It includes a support base, with a storage hopper and a pump at the top of the support base, and a lifting mechanism on one side of the storage hopper. This invention, through the lifting mechanism, can simultaneously lift two straight groove blocks to heights suitable for different wall heights, thereby raising the spray pipe located on one side of the lifting mechanism to a certain height to accommodate gypsum mortar laying on walls of different heights. The T-shaped block is pulled outwards, freeing it from the constraint of the limiting post, and rotated, causing the T-shaped block to drive a rotating rod to rotate. The rotating rod simultaneously drives two gears to rotate, lifting the corresponding toothed plates upwards from inside the hollow shell, so that the corresponding straight groove block rests on the roof, expanding the gypsum mortar laying height of the spray pipe. This allows for adaptation to different roof heights, thereby improving the adaptability of the device and increasing the efficiency of gypsum mortar laying.

Description

Technical Field

[0001] This utility model relates to the field of gypsum mortar laying technology, and in particular to a gypsum mortar laying device. Background Technology

[0002] In the construction industry, gypsum mortar is a commonly used building material, widely used in wall plastering, floor leveling and interior decoration projects. Its laying quality and efficiency directly affect the overall quality, aesthetics and construction progress of the building. With the continuous development of the construction industry, changes to the laying of gypsum mortar are one of the factors that improve the laying efficiency of gypsum mortar.

[0003] Pour the mixed gypsum mortar into the storage hopper. Adjust the spray pipe to match the wall height and spray the gypsum mortar onto the wall by moving it up and down.

[0004] Existing gypsum mortar laying devices require manual operation to spray the gypsum mortar onto one side of the wall while holding the output end at a certain distance from the wall. When laying the gypsum mortar at the required height, manual labor is required to climb to a higher position. As the wall laying construction time increases, the efficiency of manual labor gradually decreases. Therefore, a new gypsum mortar laying device is proposed. Utility Model Content

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0029] Example 1

[0030] Reference Figure 1 , Figure 3 , Figure 3 and Figure 4 This is the first embodiment of the present utility model. This embodiment provides a gypsum mortar laying device, including a support base 1. The top of the support base 1 is provided with a storage hopper 4 and a material pump 5. A lifting mechanism 2 is provided on one side of the storage hopper 4. A spraying mechanism 3 adapted to the lifting mechanism 2 is installed at the bottom of the storage hopper 4. A spray pipe 6 is provided on one side of the spraying mechanism 3.

[0031] The lifting mechanism 2 includes a hollow housing 201 symmetrically installed on the top of the support base 1. A toothed plate 202 is movably installed inside the hollow housing 201. Limiting blocks 203 are connected to both sides of the toothed plate 202. A rotating rod 205 is movably connected inside the hollow housing 201. A gear 206 adapted to the toothed plate 202 is provided on the outer surface of the rotating rod 205. A straight groove block 204 is installed on the top of the toothed plate 202.

[0032] Specifically, both sides of the hollow shell 201 are provided with long sliding grooves adapted to the limiting block 203. The limiting block 203 is slidably connected inside the long sliding groove. One side of the inner cavity of the hollow shell 201 is provided with a square groove adapted to the gear 206. The gear 206 is movably installed inside the square groove. The gear 206 meshes with the toothed plate 202. When the toothed plate 202 is driven to move up and down, under the action of the limiting block 203, the toothed plate 202 moves up and down smoothly. When the gear 206 is driven to rotate, it can lift the toothed plate 202 to the moving height.

[0033] Specifically, a limiting plate 211 is provided inside the rotating rod 205. A spring 210 is installed on the limiting plate 211. A T-shaped block 208 is installed on the other side of the limiting plate 211. Several limiting posts 207 adapted to the T-shaped block 208 are arranged circumferentially on one side of the hollow shell 201. A pull rod 209 is symmetrically arranged on one side of the T-shaped block 208. Under the action of the spring 210, a certain pushing force is applied to the T-shaped block 208 through the limiting plate 211, so that the T-shaped block 208 is stuck between the two limiting posts 207, restricting the reverse rotation of the rotating rod 205, thereby lifting the straight groove block 204 at the top of the hollow shell 201 to a certain height.

[0034] Specifically, the rotating rod 205 has a circular groove inside that is adapted to the limiting plate 211. The limiting plate 211 is slidably connected inside the circular groove. The outer surface of the rotating rod 205 has a square hole that is adapted to the T-shaped block 208. The T-shaped block 208 is movably connected inside the square hole. The T-shaped block 208 is adapted to the limiting post 207. The T-shaped block 208 is pulled outward to rotate, causing the rotating rod 205 to rotate. After the rotating rod 205 has finished rotating, the T-shaped block 208 is pushed to one side of each pair of limiting posts 207 under the action of the spring 210, restricting the rotation of the T-shaped block 208.

[0035] Furthermore, the T-block 208 is pulled outward by the pull rod 209, causing the T-block 208 to break free from the restriction of the limiting post 207. During this process, the T-block 208 applies a certain pressure to the spring 210 through the limiting plate 211, causing it to deform. Then, the T-block 208 is rotated, which drives the rotating rod 205 to rotate. The rotating rod 205 drives the two gears 206 to rotate simultaneously. The gears 206 lift the corresponding toothed plate 202 upward in the hollow shell 201. The toothed plate 202 pushes the straight groove block 204 upward until it is lifted to contact the roof. At this time, the tension applied to the pull rod 209 is released. Under the action of the spring 210, the T-block 208 is pushed in the opposite direction through the limiting plate 211, pushing the T-block 208 between every two adjacent limiting posts 207, restricting the rotation of the limiting posts 207, thus fixing the straight groove block 204 at that height.

[0036] Example 2

[0037] Reference Figure 5 and Figure 6This is the second embodiment of the present invention. This embodiment is based on the previous embodiment. The spraying mechanism 3 includes a reversing wheel 306. Side plates 308 are symmetrically installed at the bottom of the storage hopper 4. Slide rods 311 are provided on opposite sides of the two side plates 308. Tensioning wheels 307 are installed at both ends of the slide rods 311. The straight groove block 204 and the hollow shell 201 are movably connected to the rotating shaft 301. The outer surface of the rotating shaft 301 is symmetrically provided with transmission sprockets 302. The outer side of the transmission sprockets 302 is connected to the transmission chain 304. A connecting block 303 is installed on one side of the transmission chain 304.

[0038] Specifically, the transmission chain 304 is fixedly installed at the right angle at the bottom of the storage hopper 4. The transmission chain 304 is connected to the outside of the reversing wheel 306. The transmission chain 304 is connected to the tension wheel 307. The nozzle 6 is installed on one side of the connecting block 303. One end of the rotating shaft 301 extends to the outside of the straight groove block 204 and is equipped with a first motor 305. The two side plates 308 are movably installed with lead screws 309 on opposite sides through bearing seats. When the rotating shaft 301 is rotated, it drives the two transmission sprockets 302 to rotate. Under the action of the reversing wheel 306, the transmission chain 304 changes the transmission direction and connects with the tension wheel 307, so that the nozzle 6 located on one side of the connecting block 303 can move up and down in the vertical direction. The gypsum mortar is laid on the wall through the nozzle 6.

[0039] Specifically, a second motor 312 is installed on one end of the lead screw 309 extending to one side of the side plate 308. Balance bars 310 are symmetrically arranged on opposite sides of the two side plates 308. A slide bar 311 is movably installed on the outside of the lead screw 309 through a threaded sleeve. The slide bar 311 is slidably connected to the outside of the balance bar 310. The input end of the pump 5 is connected to the storage hopper 4 through a pipe. The pump 5 is connected to the nozzle 6 through a pipe. Under the action of the two balance bars 310, when the lead screw 309 drives the slide bar 311 to move, the stability of the slide bar 311 during the movement is ensured, so that the two tensioning wheels 307 are always symmetrical along the lead screw 309.

[0040] Furthermore, while the straight groove block 204 is pushed upward, the second motor 312 is controlled to run. The output end of the second motor 312 drives the lead screw 309 to rotate. With the assistance of the two balance bars 310, the lead screw 309 drives the slide bar 311 to push to the other side, causing the tension wheel 307 to move accordingly. According to the length of the rise of the straight groove block 204, the tension wheel 307 is adjusted to a certain horizontal distance, so that the vertical length of the transmission chain 304 becomes longer, and the vertical height of the transmission chain 304 is adapted to the height of the wall.

[0041] Working principle: The device is connected to an external power supply and controller using a wiring harness. The mixed gypsum mortar is poured into the storage hopper 4. The pump 5 is controlled to operate, delivering the gypsum mortar through a pipeline to the spray nozzle 6, allowing it to be laid on one side of the wall. During the laying of the gypsum mortar, the first motor 305 is controlled to operate. The output of the first motor 305 drives the rotating shaft 301 to rotate. The rotating shaft 301 drives two transmission sprockets 302 to rotate simultaneously. The transmission sprockets 302 drive the corresponding transmission chains 304, causing the transmission chains 304 to change direction outside the reversing wheel 306 and drive outside the tensioning wheel 307. The transmission chain 304, with the assistance of the connecting block 303, drives the spray pipe 6 to move up and down on one side of the wall to lay gypsum mortar on one side of the wall. When encountering walls of different heights, the extension length of the toothed plate 202 needs to be adjusted. At this time, the T-block 208 is pulled outward by the pull rod 209, so that the T-block 208 is freed from the restriction of the limiting post 207. During this process, the T-block 208 applies a certain pressure to the spring 210 through the limiting plate 211, causing it to deform. Then, the T-block 208 is rotated, which drives the rotating rod 205 to rotate. The rotating rod 205 drives the two gears 206 to rotate simultaneously. As the gear rotates, the gear 206 lifts the corresponding toothed plate 202 upwards within the hollow housing 201. The toothed plate 202 pushes the straight groove block 204 upwards until it reaches contact with the roof. At this point, the tension applied to the pull rod 209 is released. Under the action of the spring 210, the T-shaped block 208 is pushed in the opposite direction by the limiting plate 211, pushing the T-shaped block 208 between every two adjacent limiting posts 207, thus restricting the rotation of the limiting posts 207. This fixes the straight groove block 204 at that height. During the adjustment of the extension height of the toothed plate 202, the second motor 312 also needs to be controlled. The second motor 312 is equipped with an electromagnetic brake at its output end. When the second motor 312 is not running, the output end of the second motor 312 can be locked. The output end of the second motor 312 drives the lead screw 309 to rotate. With the assistance of the two balance bars 310, the lead screw 309 drives the slide bar 311 to push to the other side, causing the tension wheel 307 to move accordingly. According to the length of the rise of the straight groove block 204, the tension wheel 307 is adjusted laterally by a certain distance, so that the length of the transmission chain 304 in the vertical direction becomes longer, and the vertical height of the transmission chain 304 is adapted to the height of the wall. Then, the gypsum mortar can be laid on the wall again.
