Specific embodiments

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the invention with reference to the accompanying drawings in the embodiments of the invention. Obviously, the described embodiments are only a part of the embodiments of the invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the invention without creative efforts shall fall within the scope of protection of the invention.

[0023] Embodiment 1

[0024] Please refer to Figure 1 , which is the first embodiment of the invention. This embodiment provides a technical solution: a grouting machine that is easy to clean, including a body 100 and a grouting base pipe 200 installed on one side of the body 100. A feeding mechanism 300 is provided at the top of the grouting base pipe 200 for adding slurry. The feeding mechanism 300 includes a feeding seat 301 installed on the top surface of the grouting base pipe 200. The feeding seat 301 is communicated with the inside of the grouting base pipe 200, and a feeding hopper 302 is installed on the top of the feeding seat 301. Later, the slurry can be injected from the feeding hopper 302. A plurality of disassembly and assembly components 303 are provided between the feeding hopper 302 and the feeding seat 301.

[0025] In this embodiment, preferably, an integrated rectangular insertion frame is provided on the bottom surface of the feeding hopper 302, and the rectangular insertion frame is inserted into the inner side of the top end of the feeding seat 301 for positioning when the feeding hopper 302 is installed.

[0026] A method for using a grouting machine that is easy to clean includes the following steps:

[0027] Step 1: First, assemble the feeding hopper 302 and the feeding seat 301 together through the disassembly and assembly component 303 to complete the combined assembly of the feeding mechanism 300;

[0028] Step 2: Start the body 100 to make the grouting pump inside the body 100 operate, driving the mixing wheel inside the grouting base pipe 200 to rotate;

[0029] Step 3: Inject the slurry into the feed hopper 302 so that the slurry flows into the interior of the grouting base pipe 200 through the feed seat 301;

[0030] Step 4: The slurry entering the interior of the grouting base pipe 200 will be ejected from the grouting pipe at the end of the grouting base pipe 200 under the rotation of the mixer wheel to achieve the grouting operation.

[0031] Embodiment 2

[0032] Please refer to Figures 1 to 5 , which is the second embodiment of the invention. Based on the previous embodiment, the difference is that the installation and disassembly of the feed hopper 302 can be quickly completed through the disassembly and assembly component 303, which is convenient for the subsequent disassembly and cleaning of the feed hopper 302.

[0033] Specifically, the disassembly and assembly component 303 includes a positioning rod 3031, a base block 3032, a sliding plate 3033, and a U-shaped pressing block 3034. The positioning rod 3031 is welded and fixed on the top surface of the feed seat 301, and the top end of the positioning rod 3031 penetrates through to the bottom surface of the feed hopper 302. A positioning through hole is opened at the bottom edge of the feed hopper 302 for the penetration of the positioning rod 3031, and the positioning through hole corresponds to the positioning rod 3031. The base block 3032 is fixed on the side of the feed seat 301, and the sliding plate 3033 is movably installed on the side of the base block 3032. The U-shaped pressing block 3034 is rotatably installed on the top surface of the sliding plate 3033, and one end of the U-shaped pressing block 3034 is in pressing contact with the bottom surface of the feed hopper 302 to realize the downward pressing and limiting of the bottom end of the feed hopper 302. The top end of the positioning rod 3031 is located in the notch at the end of the U-shaped pressing block 3034 to ensure that the U-shaped pressing block 3034 does not rotate by mistake during daily use. A resilient structure 3035 is provided between the sliding plate 3033 and the base block 3032, and the resilient structure 3035 includes a side sliding groove 30351 opened on the side of the base block 3032. A side sliding block 30353 and a spring 30354 are arranged in the side sliding groove 30351. One end of the side sliding block 30353 extends out of the side of the base block 3032 and is fixed to the bottom end of the sliding plate 3033, so that the sliding plate 3033 can be pushed back by the spring 30354 after sliding upward.

[0034] In this embodiment, preferably, an inner guide rod 30352 is also fixed in the side sliding groove 30351, and both the side sliding block 30353 and the spring 30354 are movably sleeved on the surface of the inner guide rod 30352 to ensure the stability of the side sliding block 30353 and the spring 30354 during sliding.

[0035] In summary, when the feed hopper 302 needs to be removed for cleaning, just push up the slide plate 3033 first, so that the side slider 30353 compresses the spring 30354, and makes the U-shaped pressing block 3034 separate from the positioning rod 3031. At this time, the U-shaped pressing block 3034 can be rotated 180 degrees, so that the U-shaped pressing block 3034 no longer blocks and limits the bottom end of the feed hopper 302. At this time, the feed hopper 302 can be directly lifted up for disassembly and cleaning, greatly improving the cleaning convenience of the feed hopper 302. During daily use, the spring 30354 will continuously apply a downward thrust to the side slider 30353, so that the U-shaped pressing block 3034 continuously presses down on the bottom end of the feed hopper 302 to ensure the installation stability of the feed hopper 302.

[0036] Embodiment 3

[0037] Please refer to Figures 1 to 5 , which is the third embodiment of the invention. This embodiment is based on the previous embodiment. The difference is that the sealing structure 3036 can ensure the connection sealing performance between the feed hopper 302 and the feed seat 301.

[0038] Specifically, the disassembly and assembly component 303 further includes a sealing structure 3036. The sealing structure 3036 includes a U-shaped rubber pad 30361 adhesively fixed to the bottom surface of the feed hopper 302. And an integral U-shaped rubber ring 30362 is provided on the bottom surface of the U-shaped rubber pad 30361. A U-shaped sealing groove 30363 corresponding to the U-shaped rubber ring 30362 is formed on the top surface of the feed seat 301. And the U-shaped rubber ring 30362 is embedded in the U-shaped sealing groove 30363, playing an effective sealing role.

[0039] In summary, when the feed hopper 302 is subsequently installed on the top of the feed seat 301, the U-shaped rubber ring 30362 will also be embedded in the U-shaped sealing groove 30363, playing a good sealing role and ensuring the connection sealing performance between the feed hopper 302 and the feed seat 301.

[0040] Although the embodiments of the invention have been shown and described (see the above detailed description), for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the invention. The scope of the invention is defined by the appended claims and their equivalents.
