Description

Technical Field

[0001] The utility model relates to the technical field of mortar storage, in particular to a dry mortar storage tank. Background Art

[0002] Dry-mix mortar is a granular or powdered material made by physically mixing dried and sieved aggregate, inorganic cementitious materials, and additives in a specific proportion. It can be used directly after adding water. After production, dry-mix mortar needs to be temporarily stored in a storage tank and can be accessed as needed.

[0003] Existing storage tanks store finished dry mortar directly inside. When the mortar needs to be discharged for use, due to the mortar's physical properties and various factors that may have affected it during transportation, some mortar often adheres to the inner wall of the tank's discharge port. This adsorption phenomenon may be due to a certain degree of stickiness between mortar particles or electrostatic attraction to the tank's inner wall under specific environmental conditions. As the mortar continues to be discharged, the amount of mortar adsorbed on the inner wall of the tank's discharge port increases, easily causing localized blockages, reducing the effective discharge space of the tank's discharge port, and thus affecting the mortar's drop efficiency.

[0045] The storage tank 1 is a cylindrical structure with a sealed upper end and an open bottom end, and has a storage cavity for storing dry mortar inside;

[0046] The lower hopper 6 is trumpet-shaped and is installed at the bottom end of the storage tank 1. The small opening of the lower hopper 6 is connected to a lower pipe 7 that communicates with the accommodating cavity.

[0047] The positioning frame 14 extends vertically upward along the bottom end of the discharge pipe 7 and can rotate circumferentially along the outer wall of the discharge pipe 7. A reciprocating screw 15 is rotatably mounted on the inner top wall thereof, and a bearing plate 17 is threadedly connected to the reciprocating screw 15;

[0048] The knocking member is provided on the carrying plate 17 and can knock the outer wall of the feeding pipe 7 when the carrying plate 17 slides along the positioning frame 14;

[0049] The driving assembly is arranged on the outer wall of the discharge pipe 7 and is used to drive the reciprocating screw 15 to rotate along its own axis.

[0050] It should be noted that: the outer wall of the storage tank 1 is connected to a support leg 2 for supporting the storage tank 1, and a plurality of support legs 2 are evenly distributed along the outer wall of the storage tank 1. The top of the storage tank 1 is also provided with a feed port 3 for feeding dry mortar into the storage tank 1. The storage tank 1 is supported by the provided support legs 2 to improve the stability of the storage tank 1 during storage. The provided feed port 3 facilitates the feeding of dry mortar into the storage tank 1 for storage. The feed port 3 is provided above the storage tank 1. After the dry mortar enters the storage tank 1 from the feed port 3, it falls to the bottom of the storage tank 1 by its own gravity.

[0051] See Figure 3-Figure 5 , striking parts include:

[0052] The fixed rack 16 has an end portion fixedly connected to the inner top wall of the positioning frame 14 and extends vertically downward along the inner top wall of the positioning frame 14;

[0053] The first gear 18 is rotatably mounted on the carrier plate 17 and meshed with the fixed rack 16. A rotating shaft 21 is rotatably mounted on the carrier plate 17, and the first gear 18 is mounted on the rotating shaft 21.

[0054] The fourth gear 22 is fixedly mounted on the end of the rotating shaft 21, and a quarter of the outer circumference of the fourth gear 22 is provided with teeth;

[0055] The knocking rod 23 can slide along the upper surface of the carrier plate 17, and its lower surface is continuously provided with tooth grooves that mesh with the teeth of the fourth gear 22, and a knocking head 24 of a flexible structure is installed at the end of the knocking rod 23;

[0056] The support plate 25 extends vertically along the upper surface of the bearing plate 17 , and a spring 27 is installed on its side wall. The other end of the spring 27 is fixedly connected to the knocking rod 23 .

[0057] Specifically, the reciprocating screw 15 is rotated to drive the supporting plate 17 to move vertically back and forth along the positioning frame 14. During the movement of the supporting plate 17, the first gear 18 rotatably installed thereon will roll and engage with the fixed rack 16 fixed on the side wall of the positioning frame 14, thereby causing the first gear 18 to rotate on the supporting plate 17 during movement. During the rotation of the first gear 18, the rotating shaft 21 will drive the fourth gear 22 to rotate, and the fourth gear 22 can drive the knocking rod 23 to move back and forth linearly. The knocking rod 23 can drive the knocking head 24 to knock back and forth on the outer wall of the discharge pipe 7, and can continuously knock on the outer wall of the discharge pipe 7, which helps to loosen impurities adhering to the discharge pipe 7, facilitate discharge, and effectively prevent blockage.

[0058] It should be noted that: when the toothed part of the fourth gear 22 begins to engage with the tooth groove of the knocking rod 23, as the fourth gear 22 rotates, its teeth push the knocking rod 23 to move upward in a straight line. When the toothed part of the fourth gear 22 is about to disengage, the knocking rod 23 reaches its maximum speed and maximum displacement in the forward motion, and its toothless part begins to correspond to the knocking rod 23. At this time, the knocking rod 23 loses the direct power transmission from the fourth gear 22, and the knocking rod 23 will return to its initial position, thereby achieving the effect of reciprocating motion of the knocking rod 23 relative to the discharge tube 7.

[0064] Specifically, the driving motor 12 drives the driving gear 13 to rotate, and the driving gear 13 can drive the movable gear ring 11 to rotate. The movable gear ring 11 drives the knocking piece installed thereon to rotate circumferentially along the discharge pipe 7, so as to achieve the effect of the knocking piece knocking on the discharge pipe 7 at multiple circumferential positions. During the rotation of the movable gear ring 11, the second gear 19 installed at the bottom end of the reciprocating screw 15 will roll and engage with the third gear 20 fixed on the outer wall of the discharge pipe 7, thereby causing the second gear 19 to electrically drive the reciprocating screw 15 to rotate along its own axis. The rotation of the reciprocating screw 15 can drive the supporting plate 17 to reciprocate and lift. During the movement of the supporting plate 17, the knocking piece can be driven to knock on the vertical outer wall of the discharge pipe 7 at multiple points, further enhancing the knocking effect on the discharge pipe.
