DETAILED DESCRIPTION

[0019] like Figures 1 to 4 As shown, the present invention discloses a coconut shell fiber reinforced coral aggregate concrete mixing and stirring device, such as Figure 1 As shown, this device is upgraded from an inclined drum stirring device, and mainly includes a mixing barrel 1 and a fiber material pipe 2 filled with coconut shell fiber, wherein two pairs of spiral blades 11 are symmetrically arranged around the inner side of the mixing barrel 1, and the mixing barrel 1 is fixed on a bracket, and a driving structure is arranged on the bracket. The mixing barrel 1 is driven to rotate by a motor. During the rotation of the mixing barrel 1, the spiral blades 11 in the mixing barrel 1 rotate, move, and flip up the concrete to make the concrete mixed evenly. In order to solve the problem of uneven mixing of coconut shell fiber, this device adds a fiber material pipe 2, refer to Figure 2 and Figure 3 The fiber material pipe 2 includes a connecting feed pipe 21 and a discharge pipe 22. The feed pipe 21 is located above the mixing barrel 1. The pipe surface of the feed pipe 21 is circular. The feed pipe 21 is connected to the discharge pipe 22. The discharge pipe 22 extends from the material port of the mixing barrel 1. The pipe surface of the discharge pipe 22 is set to be semicircular. The discharge pipe 22 has a flat bottom plane, and the bottom plane of the discharge pipe 22 faces downward. The bottom plane of the discharge pipe 22 is arranged to open a plurality of grooves 221; an extension rod 12 is coaxially fixedly connected to the inside of the mixing barrel 1, and a plurality of scraping strips 13 are arranged on the extension rod 12. Each scraping strip 13 corresponds to a groove 221. The width of the scraping strip 13 is smaller than the width of the groove 221. As the mixing barrel 1 rotates, the scraping strip 13 extends from the groove 221 into the discharge pipe 22 to bring out the coconut shell fiber in the discharge pipe 22.

[0020] This device is provided with a fiber material pipe 2 and a scraper 13 for taking out the coconut shell fiber from the fiber material pipe 2, so that in this device, when the mixing barrel 1 is mixing the mixed concrete, the coconut shell fiber is continuously and slowly brought into the concrete as the concrete is stirred. In this device, the feed pipe 21 is filled with coconut shell fiber at any time to ensure that the coconut shell fiber in the discharge pipe 22 connected to the feed pipe 21 is full. When the mixing barrel 1 does not rotate, the scraper 13 does not move, and the coconut shell fiber in the discharge pipe 22 is supported by the bottom plane and filled in the discharge pipe 22. Although there is a groove 221, the coconut shell fiber The coconut shell fibers are interlaced with each other to form a volume structure, so they will not fall from the bottom plane. Even if they fall, only a small amount of coconut shell fibers will fall, which will not affect the uniformity of the concrete. The extension rod 12 rotates coaxially with the mixing barrel 1 under the rotation of the mixing barrel 1. The scraper strip 13 on the extension rod 12 extends into and out of the strip groove 221 on the bottom plane of the discharge pipe 22 as the extension rod 12 rotates, so that the coconut shell fibers can be continuously brought out. This device can add coconut shell fibers to concrete in real time when mixing concrete, avoiding the situation where the coconut shell fibers are added at one time, resulting in the clumping of coconut shell fibers and the uneven mixing of coconut shell fibers in concrete.

[0021] In a further solution, Figure 4 As shown, a spiral shaft 3 is also rotatably provided in the feeding pipe 21. The spiral shaft 3 is driven by a motor, and as the spiral shaft 3 rotates, the coconut shell fiber in the coating tube can be pushed into the feeding pipe 22, so as to ensure that the coconut shell fiber in the feeding pipe 22 is filled at all times, and the gap taken away by the scraper 13 is quickly filled, and the coconut shell fiber can be continuously brought into the concrete being mixed by the scraper 13.

[0022] In a further solution, Figure 3 As shown, the scraper bar 13 includes a straight bar 131 fixed on the extension rod 12, and a baffle bar 132 arranged on the side of the straight bar 131. By setting the scraper bar 13 with a cross structure, the baffle bar and the straight bar 131 can bring out the coconut shell fibers interlaced in the discharge pipe 22 as much as possible, avoiding the situation where a single straight stick structure brings out a small amount of coconut shell fibers, or cannot bring out the coconut shell fibers.

[0023] In a further solution, Figure 2 and Figure 3 As shown, the fiber material tube 2 also includes a long brush 23, which is located below the feed tube 22. The long brush 23 is fixed to the feed tube 22 through an extended support frame structure. When the scraper strip 13 rotates to the bottom, the long brush 23 overlaps with the rows of scrapers 13.

[0024] In this structure, by setting a long strip baffle brush 23, the coconut shell fiber on the scraper bar 13 passing through the long strip baffle brush 23 can be blocked and fall into the mixed concrete, avoiding the coconut shell fiber from being entangled on the scraper bar 13 and entering the discharge pipe 22 again as the mixing barrel 1 rotates.

[0025] In a further solution, Figure 3 As shown, the scraping bars 13 on the extension rod 12 are divided into three rows, and the three rows of scraping bars 13 are arranged at an angle on the extension rod 12. By arranging multiple rows of scraping bars 13, the speed of scraping coconut shell fibers can be increased, and the situation where the efficiency of a single scraping bar 13 is too low can be avoided.

[0026] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
