Description

Technical Field

[0001] This utility model relates to the field of mortar production technology, specifically to a quantitative additive addition mechanism for mortar production. Background Technology

[0002] The raw materials required for mortar production mainly include cementitious materials, fine aggregates, admixtures, and water. Additives are an indispensable part of mortar production, significantly improving mortar performance and enhancing construction efficiency and quality. By adding additives in precise quantities, the component ratio of each batch of mortar can be ensured to be consistent, which helps improve the quality stability of the mortar and ensures the reliability and consistency of construction results.

[0003] Chinese utility model patent CN220261473U discloses a quantitative additive addition mechanism for mortar production, including a weighing hopper and an auger conveying pipe, as well as a protective addition mechanism. The protective addition mechanism includes a sleeve, a wall plate, a U-shaped seat, a vibrating motor, a bent drop pipe, a double-port cloth sleeve, a vibration plate, and a drop ring. The discharge end of the weighing hopper is interconnected with the feed end of the auger conveying pipe. By assembling the auger conveying pipe with the weighing hopper of the quantitative addition device with the protective addition mechanism, a quantitative additive addition mechanism for mortar production can be formed. After the mortar additive is weighed and quantitatively discharged by the weighing hopper, the mortar additive can be sent by the auger conveying pipe into the feed inlet of the protective addition mechanism, which extends downward into the feed inlet of the mortar production tank, to prevent the mortar additive from flying out at the feed inlet of the mortar production tank. In addition, the protective addition mechanism can also vibrate its own structure for conveying mortar additives to ensure that a sufficient amount of mortar additive falls into the mortar production tank.

[0004] In order to connect the sleeve and the delivery pipe together, the above-mentioned quantitative addition mechanism for mortar production additives is equipped with a wall plate and a fastening bolt at one end of the sleeve. However, the above-mentioned quantitative addition mechanism for mortar production additives does not have the function of limiting the fastening bolt. During long-term vibration and use, the fastening bolt may gradually loosen due to vibration. If the fastening bolt does not have a limiting device, once it loosens to a certain extent, it may cause the connection between the sleeve and the delivery pipe to be unstable or even fall off, thereby causing a safety accident.

[0010] Furthermore, a vibration transmission plate is fixedly installed at one end of the bent pipe.

[0011] Furthermore, a drop ring is fixedly provided at one end of the double-sided cloth cover.

[0012] Compared with the prior art, the present invention provides a quantitative additive addition mechanism for mortar production, which has the following beneficial effects:

[0013] 1. The quantitative addition mechanism for mortar production additives features a protective shell. This shell not only isolates the hexagonal nut from moisture, dust, and other harmful substances in the external environment, preventing corrosion and wear and extending its service life, but also tightly encloses the nut to prevent it from loosening or falling off during vibration and use. This helps ensure a stable and reliable connection between the sleeve and the delivery pipe, significantly reducing the risk of mortar leakage, equipment damage, and other safety accidents caused by loose or fallen hexagonal nuts, thus improving the safety and reliability of the equipment.

[0014] 2. This mortar production additive quantitative addition mechanism, through the setting of an L-shaped rod, a moving plate, a return spring, and a rotating groove, pulls the L-shaped rod away from the wall panel. The L-shaped rod drives the moving plate to slide, and the return spring deforms. When the hexagonal nut moves out of the protective shell, the L-shaped rod is rotated, and the rotating groove rotates accordingly until the hexagonal nut is completely exposed. At this time, the operator can rotate the hexagonal nut. After the operation is completed, the L-shaped rod is rotated again so that the hexagonal nut is aligned with the hexagonal groove of the protective shell. The L-shaped rod is then released, and under the elastic force of the return spring, the hexagonal nut is inserted into the hexagonal groove. The operation is simple, providing great convenience for operators to quickly release and achieve the limit of the hexagonal nut, reducing the workload of operators and improving work efficiency.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-3This utility model discloses a quantitative additive addition mechanism for mortar production, including a conveying pipe 1. A weighing hopper 201 is fixedly installed on one side of the top of the conveying pipe 1. A drive motor 202 is fixedly installed on one side of the conveying pipe 1. An auger 203 is fixedly installed on the output shaft of the drive motor 202. A sleeve 301 is movably installed on the outside of the conveying pipe 1 away from the drive motor 202. A wall plate 302 is fixedly installed on one side of the sleeve 301. Threaded holes are opened on both sides of the wall plate 302, and threaded rods 303 are movably installed in the threaded holes. One end of the threaded rod 303 is fixedly provided with a... A hexagonal nut 304 is provided with a protective shell 305. An L-shaped rod 306 is fixedly provided on the opposite side of the protective shell 305. A movable plate 307 is fixedly provided at one end of the L-shaped rod 306. A return spring 308 is fixedly provided on the side of the movable plate 307 away from the L-shaped rod 306. A rotating groove 309 is provided on the outside of the movable plate 307. The rotating groove 309 and the movable plate 307 are connected by a sliding connection. A U-shaped frame 401 is fixedly provided on the top of the sleeve 301. A vibration motor 402 is provided on the top of the U-shaped frame 401.

[0021] Specifically, a sealing ring is provided on the outer wall of the end of the conveying pipe 1 away from the drive motor 202.

[0022] In this embodiment, by setting up a delivery pipe 1, when the delivery pipe 301 is connected to the sleeve 1, the sealing ring can improve the tightness of the connection between the delivery pipe 1 and the sleeve 301, thereby improving the sealing performance of the equipment.

[0023] Specifically, the rear of the protective shell 305 is provided with a hexagonal groove that matches the hexagonal nut 304.

[0024] In this embodiment, by setting a protective shell 305, the size and shape of the hexagonal groove of the protective shell 305 are adapted to the hexagonal nut 304, so that the hexagonal nut 304 can be accurately inserted into the protective shell 305, thereby improving the limiting effect.

[0025] Specifically, a bend pipe 403 is fixedly provided at one end of the sleeve 301 away from the wall panel 302, and a double-ended cloth sleeve 405 is provided at one end of the bend pipe 403.

[0026] In this embodiment, by setting up a bent drop pipe 403 and a double-port cloth sleeve 405, the additive enters the sleeve 301 and then falls into the double-port cloth sleeve 405 through the bent drop pipe 403, which greatly facilitates the addition of the additive to the feed port of the mortar production equipment tank.

[0027] Specifically, a vibration transmission plate 404 is fixedly installed at one end of the curved pipe 403.

[0028] In this embodiment, by setting up a bend pipe 403 and a vibration transmission plate 404, the sleeve 301 is vibrated and the vibration is transmitted to the bend pipe 403, and then to the vibration transmission plate 404 through the bend pipe 403. The double-ended cloth sleeve 405 vibrates accordingly and discharges the attached additive powder.

[0029] Specifically, a drop ring 406 is fixedly provided at one end of the double-mouth cloth cover 405.

[0030] In this embodiment, by setting a drop ring 406, the double-sided cloth cover 405 is kept vertically hanging down to facilitate the rapid passage of the additive.

[0031] In use, the sleeve 301 is installed at one end of the conveying pipe 1 via the wall-mounted plate 302, threaded rod 303, and hexagonal nut 304. Then, the L-shaped rod 306 is pulled away from the wall-mounted plate 302. The L-shaped rod 306 causes the moving plate 307 to slide, and the return spring 308 deforms. Simultaneously, the L-shaped rod 306 rotates, and the rotating groove 309 rotates accordingly. When the hexagonal nut 304 is aligned with the hexagonal groove of the protective shell 305, the L-shaped rod 306 is released. Under the elastic force of the return spring 308, the hexagonal nut 304 is inserted into the hexagonal groove, thus limiting the position of the hexagonal nut 304. The mortar production additive can then be poured into the weighing hopper 201 and weighed. The heavy hopper 201 can weigh and quantitatively discharge mortar production additives into the conveying pipe 1 according to the discharge volume set by the quantitative addition equipment control system. The drive motor 202 is started, and the auger 203 is driven by the drive motor 202 to auger and feed the additives into the sleeve 301. The additives enter the double-port cloth sleeve 405 through the bent drop pipe 403. The vibration motor 402 is started, and the vibration motor 402 transmits the vibration to the sleeve 301 through the U-shaped frame 401, and then to the vibration plate 404 through the bent drop pipe 403. The double-port cloth sleeve 405 vibrates accordingly, thereby discharging the attached additive powder, so that the additives can smoothly enter the tank inlet of the mortar production equipment for mortar production.

[0032] In summary, this quantitative additive addition mechanism for mortar production, by incorporating a protective shell 305, not only isolates the hexagonal nut 304 from moisture, dust, and other harmful substances in the external environment, preventing corrosion and wear and thus extending its service life, but also tightly encloses the hexagonal nut 304, preventing it from loosening or falling off during vibration and use. This helps ensure a stable and reliable connection between the sleeve 301 and the delivery pipe 1, significantly reducing the risk of mortar leakage, equipment damage, and other safety accidents caused by loosening or falling off the hexagonal nut 304, thereby improving the safety and reliability of the equipment. Furthermore, the inclusion of an L-shaped rod 306, a moving plate 307, a return spring 308, and a rotating groove 309 further enhances the safety and reliability of the equipment. Pulling one side of the wall panel 302 pulls the L-shaped rod 306, causing the moving plate 307 to slide. The return spring 308 deforms. When the hexagonal nut 304 moves out of the protective shell 305, the L-shaped rod 306 is rotated, and the rotating groove 309 rotates accordingly until the hexagonal nut 304 is completely exposed. At this point, the operator can rotate the hexagonal nut 304. After the operation is completed, the L-shaped rod 306 is rotated again so that the hexagonal nut 304 is aligned with the hexagonal groove of the protective shell 305. The L-shaped rod 306 is then released, and under the elastic force of the return spring 308, the hexagonal nut 304 is inserted into the hexagonal groove. The operation is simple and provides great convenience for operators to quickly release and achieve the limitation of the hexagonal nut 304, reducing the workload of operators and improving work efficiency.
