[0015] The technical solution of the utility model is further specifically described below through embodiments and in conjunction with the accompanying drawings.

[0016] Embodiment: A dust removal structure of a dry-mixed mortar discharging device, such as Figure 1-Figure 2As shown, it includes a mounting bracket 1, and the mounting bracket 1 includes left and right side panels 2, four direction-changing rollers 3 are set between the middle positions of the left and right side panels 2, a lower powder roller 4 is set between the front and rear ends of the two left and right side panels 2, a filter belt 5 is sleeved between the lower powder roller 4 and the direction-changing roller 3, and edge Velcro 6 is set at the left and right edges of the filter belt 5, and a plurality of middle Velcro 7 is set on the filter belt 5 between the edge Velcro 6 on both sides, and the middle Velcro 7 is arranged perpendicular to the edge Velcro 6, and the two side ends of the middle Velcro 7 are connected to the two sides. The edge Velcro 6 is integrated into a whole, and two telescopic cylinders 8 are provided on the inner sides of the two left and right side panels 2. The protruding ends of the four telescopic cylinders 8 are commonly connected to a downward pressing frame 9, and the size of the downward pressing frame 9 is consistent with the size enclosed by the two middle Velcros 7 and the two edge Velcros 6. A negative pressure wind shell 10 is provided on the upper side cover of the downward pressing frame 9, and a connecting frame 11 is provided on the lower side of the mounting bracket 1. The size of the connecting frame 11 is consistent with the size of the downward pressing frame 9, and a dust cover 12 is provided on the lower side of the connecting frame 11.

[0017] A dust discharge hood 13 is provided on the front side of the dust hood 12; the dust discharge hood 13 covers the lower powder roller 4 on the front side of the mounting bracket 1 inside; the negative pressure wind shell 10 is sealed and connected to the downward pressure frame 9; an opening 14 for leading out the negative pressure wind shell 10 is provided on the left and right side panels 2 on one side of the mounting bracket 1; a drive motor 15 is provided on the left and right side panels 2 on one side at a position corresponding to the lower powder roller 4, and the drive shaft of the drive motor 15 is fixedly connected to the corresponding lower powder roller 4.
