[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Reference Figure 1-Figure 4 The utility model provides an embodiment: a pneumatic conveying pump for fly ash transportation, comprising a support seat 1, the top four corners of the support seat 1 are all threadedly connected with bolts 16, the external bolts of the bolts 16 are connected with a connecting box 2, the two connecting boxes 2 are symmetrically distributed, the top four corners of the connecting box 2 are all threadedly connected with bolts 2 17, the external thread of the bolts 2 17 is connected with a pump body 3, the internal rotation connection of the connecting box 2 is two connecting rods 4, the external fixed connection of the connecting rod 4 is a plurality of crushing blades 5, the front end of the connecting rod 4 is fixedly connected with a gear 6, the adjacent sides of the two gears 6 are meshed, the rear side of the gear 6 is rotatably connected with the front side of the connecting box 2, the front end of the support seat 1 is fixedly connected with a motor 7, the output end of the motor 7 is fixedly connected with the front end of the left gear 6, a limit assembly is arranged inside the connecting box 2, a screen 10 is installed inside the limit assembly, the external of the screen 10 is slidably connected with the inner wall of the connecting box 2, a vibration assembly is installed on the lower side of the limit assembly, and connecting pipes 15 are installed on both sides of the support seat 1.

[0025] Specifically, the connecting box 2 connects the support seat 1 and the pump body 3, so that the fly ash can enter the interior of the support seat 1. The support seat 1 is the base part of the delivery pump, and is connected to the connecting pipe 15 to form a delivery channel. At this time, by starting the pump body 3 to operate, the pump body 3 can transport the fly ash. The connecting box 2 limits the connecting rod 4 and the gear 6, so that they can rotate smoothly. The connecting box 2 fixes the motor 7, so that the motor 7 does not shake during operation. The crushing blades 5 on the left and right sides are symmetrically distributed and rotate in the direction of the adjacent side, so that the fly ash inside the connecting box 2 can be crushed. The connecting box 2 limits the internal screen 10, so that the screen 10 can slide smoothly. The screen 10 can screen the fly ash, so that the fly ash that meets the size can directly enter the interior of the support seat 1, and the fly ash that is larger than the size can be repeatedly crushed by the crushing blades 5 until the holes that meet the screen 10 fall into the interior of the support seat 1.

[0026] The limiting assembly includes four slide grooves 8, which are respectively opened at the four corners of the inner wall of the connection box 2. The inside of the slide groove 8 is slidably connected with a slider 9, and the inner sides of the four sliders 9 are respectively fixedly connected to the four outer corners of the screen 10.

[0027] Specifically, the four slide grooves 8 are distributed in a rectangular shape and limit the internal slider 9, so that the slider 9 can slide smoothly, thereby making the force on the screen 10 more uniform, so that the screen 10 can slide up and down more smoothly.

[0028] The vibration assembly includes a mounting groove 11, which is opened on the lower side of the slide groove 8. The upper side of the mounting groove 11 is connected to the lower side of the slide groove 8. A spring 12 is fixedly connected to the lower side of the inner wall of the slide groove 8. The top end of the spring 12 is fixedly connected to a limiting block 13. The outside of the limiting block 13 is slidably connected to the inside of the mounting groove 11. The top end of the limiting block 13 is fixedly connected to a push rod 14. The top end of the push rod 14 is fixedly connected to the bottom end of the slider 9. The outside of the push rod 14 is slidably connected to the inside of the mounting groove 11.

[0029] Specifically, the four mounting grooves 11 are distributed in a rectangular shape and are opened on the lower side of the slide groove 8. The mounting grooves 11 limit the internal limit blocks 13 and the push rods 14, so that the slider 9 can slide up and down stably. When the screen 10 moves downward, the spring 12 can be stably squeezed to produce elastic deformation. When the spring 12 performs a reset movement, it can push the screen 10 downward in the reverse direction. Due to the characteristics of the spring 12, the screen 10 can move back and forth, thereby improving the screening efficiency.

[0030] Working principle: when it is necessary to crush the fly ash, the fly ash is poured into the connection box 2 through the pump body 3, so that it can impact the screen 10, and then the screen 10 can drive the slider 9 to move downward, and then the slider 9 can drive the limit block 13 to move downward through the push rod 14, and then the limit block 13 can squeeze the spring 12, and then the spring 12 can do a reset movement, so that the spring 12 can push the push rod 14 to move upward through the limit block 13, and then the push rod 14 can push the slider 9 to move upward, and then the screen 10 can move up and down reciprocatingly, so that the screen 10 has a higher screening efficiency for the fly ash. By starting the motor 7, the motor 7 can drive the gear 6 on the left to rotate, and then the gear 6 on the left can drive the gear 6 on the right to rotate, so that the two connecting rods 4 can rotate simultaneously and in relative directions, so that the connecting rod 4 can drive the crushing blades 5 to crush the fly ash, and the fly ash passed through the screen 10 can be repeatedly crushed by the crushing blades 5, so that the quality of the crushed fly ash is higher, and the fly ash can be prevented from clogging the pipeline when it is transported, thereby greatly reducing the number of times workers clean it, thereby reducing the labor intensity of workers, and also ensuring that the transportation efficiency will not be reduced, making it more economical to use.

[0031] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
