Description

Technical Field

[0001] The utility model belongs to the technical field related to concrete spraying, in particular to a wet-type shotcrete spraying machine. Background Art

[0002] Wet shotcrete refers to mixing cement, coarse and fine aggregates and water together in a certain mix ratio. Then, with the help of various types of wet sprayers, the mixed concrete is transported to the nozzle through a feed hose, and liquid accelerator is added at the nozzle. Compressed air is used to supply energy to form a material bundle of concrete, which is then sprayed from the nozzle onto the surrounding rock surface.

[0003] However, when using a sprayer, concrete needs to be poured onto the vibrating screen on the sprayer. Since there is no scraping device to scrape the concrete on the vibrating screen, it will be blocked when there is too much concrete on the vibrating screen. At the same time, the scraping structure collides with the concrete for a long time, which makes it easy to break and damage the scraping structure. However, it is not convenient to assemble and disassemble the scraping structure, which affects the mixing efficiency of the concrete. To this end, we provide a wet shotcrete sprayer to solve the above problems. Utility Model Content

[0004] The utility model aims to provide a wet shotcrete spraying machine, which controls the rotation of a rotating rod by a motor so that a scraper can scrape the screen to avoid blockage of the vibrating screen. At the same time, the T-shaped block and the T-shaped opening are used in conjunction to realize the assembly and disassembly of the rotating rod, which is convenient for replacement.

[0005] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0006] The utility model discloses a wet-type shotcrete spraying machine, comprising a spraying machine body; a vibrating screen is fixed on the upper end surface of the spraying machine body; a vertical bar is fixed on the upper end surface of the spraying machine body located on the left side of the vibrating screen; a motor is fixed on the protruding end of the vertical bar; a buffer column is bolted to the rotating shaft end of the motor; a rotating rod is arranged directly below the buffer column; four scraping bars connected to the screen surface of the vibrating screen are fixed on the peripheral side wall of the rotating rod; an assembly column is arranged between the buffer column and the rotating rod; a connecting rod is fixed on the lower end surface of the assembly column; a T-shaped opening is opened on the lower end surface of the connecting rod; a T-shaped block inserted into the inner position of the T-shaped opening is fixed on the upper end surface of the rotating rod.

[0007] The utility model is further configured such that a movable hole is provided in the inner position of the buffer column, and a limiting hole is provided on the lower end surface of the buffer column and is connected to the inner portion of the movable hole, wherein the aperture of the limiting hole is smaller than the aperture of the movable hole.

[0008] The utility model is further configured such that the upper end portion of the assembly column passes through the position of the limiting hole and is located in the movable hole, and a movable plate sliding in the inner position of the movable hole is fixed on the upper end surface of the assembly column.

[0009] The utility model is further configured such that buffer springs are fixed to the upper and lower end surfaces of the movable plate, and the buffer spring located below the movable plate is sleeved on the assembly column.

[0010] The utility model is further configured such that a retaining cylinder is sleeved on the peripheral side of the connecting rod, and the lower end portion of the retaining cylinder is sleeved on the peripheral side position of the T-shaped block.

[0011] The utility model is further configured such that a pushing spring sleeved on the connecting rod is fixed to the upper end surface of the retaining cylinder, and the upper end surface of the pushing spring is fixedly connected to the lower end surface of the assembly column.

[0012] The utility model has the following beneficial effects:

DETAILED DESCRIPTION

[0025] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example 1

[0026] See also Figures 1 to 6 The utility model is a wet shotcrete spraying machine, which controls the rotation of the rotating rod 4 through the motor 201, so that the scraper 401 scrapes the screen to avoid clogging of the vibrating screen 3. At the same time, the T-shaped block 402 and the T-shaped port 604 are used in conjunction to realize the assembly and disassembly of the rotating rod 4, which is convenient for replacement.

[0027] Specifically, the jet machine body 1; the upper end face of the jet machine body 1 is fixed with a vibrating screen 3, the upper end face of the jet machine body 1 located on the left side of the vibrating screen 3 is fixed with a vertical bar 2, the protruding end of the vertical bar 2 is fixed with a motor 201, the rotating shaft end of the motor 201 is bolted with a buffer column 5, a rotating rod 4 is arranged directly below the buffer column 5, four scraping bars 401 connected to the screen surface of the vibrating screen 3 are fixed to the peripheral side wall of the rotating rod 4, an assembly column 6 is arranged between the buffer column 5 and the rotating rod 4, the lower end face of the assembly column 6 is fixed with a connecting rod 603, the lower end face of the connecting rod 603 is provided with a T-shaped opening 604, and the upper end face of the rotating rod 4 is fixed with a T-shaped block 402 inserted into the internal position of the T-shaped opening 604.

[0028] The operation process of this embodiment is as follows: through the setting and use of the above-mentioned structure, when controlling the operation of the sprayer body 1, in order to avoid clogging of the vibrating screen 3, the motor 201 can be controlled to work, thereby the motor 201 will drive the buffer column 5 to rotate, and thereby drive the scraper bar 401 to rotate through the rotating rod 4, thereby directly driving the scraper bar 401 to scrape the concrete on the screen of the vibrating screen 3, avoiding clogging of the screen on the vibrating screen 3. At the same time, when it is necessary to disassemble the rotating rod 4, the rotating rod 4 is moved to drive the T-shaped block 402 to move out of the T-shaped opening 604, so that the rotating rod 4 is disconnected from the assembly column 6. At this time, the rotating rod 4 can be disassembled, and the T-shaped block 402 is inserted into the T-shaped opening 604, so that the rotating rod 4 can be assembled and connected with the connecting rod 603, and then assembled and connected with the buffer column 5, thereby realizing the assembly and disassembly of the rotating rod 4, which is convenient for replacement. Example 2

[0029] See also Figure 3 and Figure 4 On the basis of Example 1, the buffer spring 602 is provided to facilitate the resetting of the scraper strip 401 and ensure that the scraper strip 401 can work normally.

[0030] Specifically, a movable hole 502 is provided in the internal position of the buffer column 5, and a limiting hole 501 connected to the interior of the movable hole 502 is provided on the lower end surface of the buffer column 5. The aperture of the limiting hole 501 is smaller than the aperture of the movable hole 502. The upper end portion of the assembly column 6 passes through the position of the limiting hole 501 and is located in the movable hole 502. The upper end surface of the assembly column 6 is fixed with a movable plate 601 that slides in the internal position of the movable hole 502. The upper and lower end surfaces of the movable plate 601 are fixed with buffer springs 602. The buffer spring 602 located below the movable plate 601 is sleeved on the assembly column 6.

[0031] The operating process of this embodiment is as follows: since the screen plane on the vibrating screen 3 is uneven, the scraper bar 401 will move up and down when it rotates. Since the movable plate 601 is inside the movable hole 502, the scraper bar 401 will control the assembly column 6 to move up and down, and then the movable plate 601 will pull the buffer spring 602 below and compress the buffer spring 602 above. The buffering push of the two buffer springs 602 will reduce the amplitude of the up and down movement of the scraper bar 401. Example 3

[0032] See also Figure 3 and Figure 5 On the basis of Example 1, the retaining cylinder 7 is sleeved on the connecting rod 603 to limit the position of the T-shaped block 402 and the T-shaped opening 604, thereby preventing the T-shaped block 402 from escaping from the T-shaped opening 604 at will.

[0033] Specifically, a retaining cylinder 7 is sleeved on the circumferential side of the connecting rod 603, and the lower end of the retaining cylinder 7 is sleeved on the circumferential side of the T-shaped block 402. The upper end surface of the retaining cylinder 7 is fixed with a pushing spring 701 sleeved on the connecting rod 603, and the upper end surface of the pushing spring 701 is fixedly connected to the lower end surface of the assembly column 6.

[0034] The operation process of this embodiment is as follows: when the T-shaped block 402 needs to be moved out of the internal position of the T-shaped opening 604, the blocking cylinder 7 can be controlled to move upward, and then the blocking cylinder 7 will compress the pushing spring 701 to expose the T-shaped block 402, so that the T-shaped block 402 can be moved out of the T-shaped opening 604. At the same time, the blocking cylinder 7 is limited by the pushing spring 701, so that the blocking cylinder 7 will not move up and down at will.
