[0025] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0026] Embodiment 1:

[0027] Please refer to Figures 1-5 The utility model provides a discharging device for concrete production, including tank body 1, tank body 1 is installed on support 2, the bottom of tank body 1 is provided with discharging pipe 11, is fixedly installed with mounting plate 12 on discharging pipe 11, and the output end of motor 13 on mounting plate 12 is connected with first gear 14, and first gear 14 is engaged with second gear 15, and second gear 15 is rotatably installed on discharging pipe 11, and the bottom of second gear 15 is provided with connecting piece 5, and connecting piece 5 is installed with cleaning piece 6, and cleaning piece 6 includes mounting frame 61, and fixed rod 65 is fixedly installed in the middle of mounting frame 61, and helical blade 63 is arranged on fixed rod 65, and the both sides of fixed rod 65 are provided with scraper 64, and scraper 64 is fixedly installed on mounting frame 61, and one side of scraper 64 is provided as inclined scraper blade;

[0028] The inclined scraper blade of scraper 64 is attached to the inner wall of discharging pipe 11, and protruding tooth 641 is equidistantly arranged on the scraper blade of scraper 64;

[0029] Specifically, the cleaning member 6 is installed on the connecting member 5 in the normal state, the scraper 64 and the helical blade 63 in the cleaning member 6 are arranged in the discharging pipe 11, when the tank body 1 discharges, the operator starts the motor 13 installed on the mounting plate 12. The motor 13 operates, and the output end drives the first gear 14 to rotate. Since the first gear 14 is engaged with the second gear 15, the rotation of the first gear 14 will drive the second gear 15 to rotate, and the second gear 15 is rotatably installed on the discharging pipe 11, when it rotates, the connecting member 5 at the bottom will rotate synchronously. The connecting member 5 is installed with the cleaning member 6, so the cleaning member 6 will also make a circular motion around the center axis of the discharging pipe 11;

[0030] The mounting frame 61 in the cleaning member 6 drives the fixed rod 65 to rotate, and the helical blade 63 on the fixed rod 65 rotates, and the helical blade 63 plays a role of pushing and stirring the concrete in the discharging pipe 11 during rotation, which helps the rapid discharge of the concrete. At the same time, the scraper 64 installed on the mounting frame 61 also rotates around the inner wall of the discharging pipe 11. The inclined blades of the scraper 64 are in close contact with the inner wall of the discharging pipe 11, and can directly scrape the concrete on the inner wall during rotation. And the scraper 64 is provided with equidistant protrusions 641 on the blades, which can cut into the concrete and break the bonding force between the concrete and the inner wall, so as to scrape the concrete and further enhance the scraping effect, even if the concrete has high adhesion, it can also be effectively peeled off from the inner wall.

[0031] Further, in order to realize the convenient installation and disassembly of the cleaning member 6, please refer to Figures 1-5 The mounting frame 61 is provided with a helical hole 62 at both ends;

[0032] The connecting member 5 includes a connecting frame 51, which is fixedly installed at the bottom of the second gear 15, and the connecting plate 52 is fixedly installed on the connecting frame 51, and the helical rod 53 is installed on the connecting plate 52 and is helically connected with the helical hole 62;

[0033] The connecting frame 51 is L-shaped, and the connecting rod 54 is slidably installed on the connecting frame 51, the top end of the connecting rod 54 is fixedly connected with the helical rod 53 through the connecting disc, and the low end of the connecting rod 54 is fixedly installed with the knob 55;

[0034] The supports 2 on both sides of the tank body 1 are fixedly installed on the bottom plate 3, and the collecting groove 4 is placed on the bottom plate 3.

[0035] Specifically, when the cleaning member 6 is installed, the mounting frame 61 of the cleaning member 6 is placed on the connecting plate 52, and the screw holes 62 at both ends thereof are aligned with the screw rods 53 on the connecting plate 52 in the connecting member 5, the knob 55 is rotated, the knob 55 drives the connecting rod 54 to slide on the connecting frame 51, and at the same time, the screw rod 53 is controlled to rotate, so that the screw rod 53 moves upward and is screw-connected with the screw hole 62, thereby enabling the mounting frame 61 to be firmly mounted on the connecting plate 52. When disassembling, the knob 55 is reversely rotated, the knob 55 drives the screw rod 53 to reversely rotate through the connecting rod 54, so that the screw rod 53 is gradually separated from the screw hole 62, and after the screw rod 53 is completely separated from the screw hole 62, the cleaning member 6 can be removed.

[0036] When the scraper 64, the screw blade 63 and other components of the cleaning member 6 are worn or damaged, the cleaning member 6 can be quickly disassembled for replacement or maintenance, without the need to disassemble the entire discharging device. In the concrete production process, the cleaning member 6 may be attached with a large amount of concrete residues and other sundries. Through the convenient installation and disassembly mode, the cleaning member 6 can be regularly removed for thorough cleaning, so as to prevent the sundries from affecting the cleaning effect of the cleaning member 6, thereby ensuring the cleanliness of the inner wall of the discharging pipe 11 and avoiding the blockage of the discharging pipe 11.

[0037] The top end of the connecting rod 54 is fixedly connected with the screw rod 53 through the connecting disc, and the bottom end is fixedly connected with the knob 55, so that the screw rod 53, the connecting rod 54 and the knob 55 form an integral whole, and the connecting rod 54 and the screw rod 53 are limited by the knob 55 and the connecting disc. When the cleaning member 6 is disassembled, the screw rod 53 will not be separated from the connecting frame 51 and fall off and be lost, so that the screw rod 53 is always connected with the connecting frame 51, thereby facilitating the installation and use next time.

[0038] Working principle: when the tank body 1 needs to be discharged, the operator starts the motor 13 installed on the mounting plate 12, the motor 13 operates, the output end drives the first gear 14 to rotate, the first gear 14 is engaged with the second gear 15, thereby driving the second gear 15 to rotate, and the connecting member 5 at the bottom of the second gear 15 rotates synchronously. The connecting member 5 is installed with the cleaning member 6, so that the cleaning member 6 rotates around the central axis of the discharging pipe 11. The screw blade 63 in the cleaning member 6 plays a role in pushing and stirring the concrete in the discharging pipe 11 during rotation, which helps the concrete to be discharged quickly.

[0039] At the same time, the scraper 64 installed on the mounting frame 61 rotates around the inner wall of the discharging pipe 11. The inclined scraper of the scraper 64 is attached to the inner wall of the discharging pipe 11 and directly scrapes the concrete on the inner wall during rotation. The equidistant protrusions 641 on the scraper cut into the concrete, break the bonding force between the concrete and the inner wall, and scrape the concrete, thereby further enhancing the scraping effect and avoiding the residue of the concrete on the inner wall of the discharging pipe 11, thereby ensuring the smooth discharging.
