DETAILED DESCRIPTION

[0034] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 , a mortar unloading device, including collecting box 1, the upper side of collecting box 1 is provided with unloading cleaning device 8. Unloading cleaning device 8 includes the upper side unloading pipe 10 that is communicated in collecting box 1, two connecting plates 14 that are fixedly connected in the side of unloading pipe 10, second drive motor 15 that is fixedly installed in the upper side of connecting plate 14, second rotating shaft 21 that is fixedly connected in the output end of second drive motor 15, winding roller 22 that is fixedly connected in the output end of second rotating shaft 21, connecting rope 16 that is fixedly connected in the outer side of winding roller 22, scraping plate 18 that is fixedly connected in the side of connecting rope 16 away from winding roller 22 and counterweight 19 that is inserted in the interior of scraping plate 18.

[0035] Wherein, the top end of connecting rope 16 penetrates unloading pipe 10 and extends to its interior, the end of unloading pipe 10 close to connecting rope 16 is inserted with sealing ring, the outer side of scraping plate 18 is abutted in the inner wall of unloading pipe 10, the front end face of collecting box 1 is inserted with box plate 2, the interior of box plate 2 is inlaid with two observation windows 3, and the two observation windows 3 are horizontally arranged.

[0036] It should be noted that the sealing ring can prevent the connecting rope 16 from bringing the mortar in the discharge pipe 10 out when moving, and the sealing ring can also hang the mortar attached to the surface of the connecting rope 16. The end of the scraping plate 18 close to the discharge pipe 10 is in a conical structure, which can easily scrape the mortar adhered to the inner wall of the discharge pipe 10 when moving, so as to achieve the purpose of cleaning the inner wall of the discharge pipe 10. The sealing ring is made of rubber material. The outer side of the connecting rope 16 extends through the inner wall of the sealing ring to the inside of the discharge pipe 10. The outer side of the scraping plate 18 is bonded with an anti-sticking layer made of aluminum foil and plastic film. When the scraping plate 18 moves vertically in the discharge pipe 10, the anti-sticking layer can effectively prevent the mortar from adhering to the surface of the scraping plate 18. Moreover, the conical structure can better scrape the adhered mortar. The counterweight 19 is directly inserted into the middle of the inner side of the scraping plate 18, which can increase the overall weight of the scraping plate 18. The aluminum foil has excellent waterproof and moisture-proof performance, which can be used as an isolation layer to prevent the mortar from adhering to the base material. The plastic film can be used as a physical isolation layer to reduce the contact between the mortar and the base material, thereby avoiding adhesion. The second drive motor 15 is of RF-300CA type. The observation window 3 is made of super white glass. The surface of the super white glass is smooth and has high light transmittance, so it is not easy to adsorb mortar and other impurities, and therefore has good anti-mortar adhesion capacity.

[0037] Please refer to Figure 1 and Figure 3 In the embodiment, the inside of the discharge pipe 10 is provided with a blocking assembly. The blocking assembly includes a first drive motor 9 fixedly installed on the front end face of the discharge pipe 10, a first rotating shaft 11 fixedly connected to the output end of the first drive motor 9, and a baffle 12 sleeved on the outer side of the first rotating shaft 11.

[0038] The side of the discharge pipe 10 is rotatably sleeved with two guide wheels 17. The surfaces of the two guide wheels 17 are drivingly connected to the outer side of the connecting rope 16. The right side of the discharge pipe 10 is internally provided with a limiting groove 13 matched with the baffle 12.

[0039] It should be noted that the first rotating shaft 11 can drive the baffle 12 to rotate by 90 degrees inside the discharge pipe 10. When not discharging, the baffle 12 is abutted by the first rotating shaft 11 on the inner wall of the discharge pipe 10 to prevent other objects from entering the collecting box 1 from the discharge pipe 10, thereby achieving the isolation effect. The guide wheels 17 can help the connecting rope 16 to move and play a transmission role, thereby reducing the resistance and having a certain guiding property. The limiting groove 13 can keep the outer side of the baffle 12 in a planar state with the inner wall of the discharge pipe 10 during rotation, thereby facilitating subsequent scraping of the mortar adhered to the surface of the baffle 12. The first drive motor 9 is a ZYT type motor with high precision and strong reliability. The outer side of the guide wheel 17 is attached with a non-slip layer made of rubber pad. When the connecting rope 16 moves on the surface of the guide wheel 17, the sliding phenomenon can be avoided.

[0040] Please refer to Figure 1 、 Figure 2 and Figure 5 In this embodiment, the side of the collection box 1 is provided with a dust suction assembly, which includes two connecting pipes 7 communicated at the side of the collection box 1, a dust collection box 4 communicated at the lower side of the connecting pipe 7, an internal dust suction fan 5 inlaidly installed at the lower side of the dust collection box 4, and an internal dust isolation net 6 slidably connected to the dust collection box 4.

[0041] The suction force generated by the dust suction fan 5 cooperates with the connecting pipe 7 to suck part of the dust generated by the falling of the mortar in the collection box 1, so as to avoid the scattering of the dust when the mortar is taken out, which is easy to be inhaled into the body and cause harm to the body. The dust collection box 4 is internally provided with a mounting hole 20 matched with the dust isolation net 6.

[0042] It should be noted that the mounting hole 20 can insert the dust isolation net 6 into the dust collection box 4, and also facilitate the subsequent removal of the dust isolation net 6 from the dust collection box 4 for cleaning the filtered dust. The dust collection box 4 is fixedly connected with a straight sliding rail matched with the dust isolation net 6, so as to meet the guiding effect of the dust isolation net 6 when the dust isolation net 6 is moved into or out of the dust collection box 4. The dust isolation net 6 is arranged at the upper end of the dust suction fan 5, which can avoid the contact between the absorbed dust and the dust suction fan 5, and prolong the service life of the dust suction fan 5.

[0043] The working principle of the above embodiment is as follows:

[0044] The first drive motor 9 drives the first rotating shaft 11 to rotate the baffle 12 downward and clamp it into the limiting groove 13. At this time, the discharge pipe 10 and the collection box 1 are in communication with each other, and the mortar is discharged from the upper side of the discharge pipe 10 into the collection box 1. The discharge condition of the mortar in the collection box 1 can be directly observed through the observation window 3. During the discharging process, the dust collection fan 5 is started, and the connecting pipe 7 collects the dust generated when the mortar in the collection box 1 is impacted. The dust enters the upper end of the dust collection net 6 in the dust collection box 4 to be isolated, avoiding being discharged from the dust collection box 4. After the discharging of the mortar in the collection box 1 is completed, the second drive motor 15 is started to loosen the outer connecting rope 16 of the winding roller 22, so that the scraping plate 18 moves vertically downward under the action of the downward gravity generated by the counterweight 19. During the movement, the outer side of the scraping plate 18 abuts against the inner wall of the discharge pipe 10 to scrape off the residual mortar and drop it into the collection box 1. After the baffle 12 is clamped into the limiting groove 13, it maintains the same plane with the inner wall of the discharge pipe 10. The scraping plate 18 simultaneously scrapes off the residual mortar outside the baffle 12, avoiding the residual mortar in the discharge pipe 10 from being naturally dried to block the discharge pipe 10 and cause difficulty in later discharging. After the scraping is completed, the second drive motor 15 starts to wind the connecting rope 16, and the scraping plate 18 moves to the top of the discharge pipe 10 to wait for the next use. The first drive motor 9 drives the baffle 12 to rotate upward and abut against the inner wall of the discharge pipe 10 to form a vertical state, thereby isolating the discharge pipe 10 from the collection box 1.
