Description

Technical Field

[0001] The utility model relates to the technical field of concrete mortar, in particular to a mortar admixture feeding mechanism. Background Art

[0002] Mortar admixture refers to one or more chemical substances added to improve the performance of mortar during the mortar production process. Conventional mortar admixtures can improve the strength, durability, fluidity and adhesion of mortar. The use of mortar admixtures helps to optimize construction performance, improve project quality, and meet specific environmental and functional requirements. The mortar admixture feeding mechanism is a device used to evenly add mortar admixtures during the concrete mortar mixing process in order to improve the performance of mortar.

[0003] However, the feeding of traditional mortar admixtures is usually directly discharged into the mortar admixture through a feeding hopper or a feeding box. When the amount of mortar admixture fed is large, it is more likely to accumulate in the feeding port of the feeding hopper or the feeding box during the feeding process, making it difficult to discharge, resulting in blockage. The blockage not only causes feeding interruptions, but also requires frequent cleaning and maintenance, which increases the difficulty of operation and downtime, and reduces production efficiency. Utility Model Content

DETAILED DESCRIPTION

[0018] 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.

[0019] See also Figure 1-Figure 3 An embodiment of the utility model provides a mortar admixture feeding mechanism, comprising: a mixing tank 1 and a feeding box 2.

[0020] Among them, Figure 1-Figure 3 As shown, the feeding box 2 is installed on the top of the mixing tank 1, and the top of the feeding box 2 is connected to the feeding hopper 3. The inner wall of the feeding box 2 is symmetrically provided with two inclined surfaces 10. A first motor 4 is installed on one side of the feeding box 2. The rotating shaft of the first motor 4 passes through the feeding box 2 and is fixedly connected with a feeding roller 13. One end of the feeding roller 13 is rotatably installed on the inner wall of one side of the feeding box 2, and the outer wall of the feeding roller 13 is symmetrically provided with no less than three arc-shaped convex ridges.

[0021] When in use, after the mortar admixture enters the feeding box 2 through the feeding hopper 3, the feeding roller 13 is driven to rotate by starting the first motor 4. When the feeding roller 13 rotates, the arc-shaped convex ridges can be used to close and open the bottom opening of the feeding box 2, so as to flexibly control the feeding state of the mortar admixture in the box. At the same time, the rotation of the feeding roller 13 can make the mortar admixture slide along the inclined surface 10.

[0022] For further reference, Figure 2 The top of the mixing tank 1 is connected to a slurry delivery pipe 6, and the bottom of the mixing tank 1 is connected to a slurry discharge pipe 8. Concrete mortar is input into the mixing tank 1 through the slurry delivery pipe 6 for mixing, and is discharged to the outside through the slurry discharge pipe 8 after mixing.

[0023] It should be noted that the outer wall of the feeding roller 13 is in contact with the inner wall of the bottom opening of the feeding box 2 .

[0024] In this embodiment, Figure 1-Figure 4 As shown, the inner wall of the feeding box 2 is fixedly connected with a support plate 11, and a movable rod 12 runs through the inside of the support plate 11. The bottom end of the movable rod 12 is attached to the outer wall of the feeding roller 13. The outer wall of the movable rod 12 is sleeved with a spring 15, and the top end of the spring 15 is fixedly connected to the bottom of the support plate 11.

[0025] When in use, one end of the bottom of the movable rod 12 is in contact with the feeding roller 13. When the feeding roller 13 rotates, the curved ridges can be used to push the movable rod 12 upward. After the movable rod 12 passes through the curved ridges, the spring 15 provides a rebound force to lower the movable rod 12, thereby controlling the movable rod 12 to rotate up and down when the feeding roller 13 rotates to feed the mortar admixture.

[0026] Furthermore, a rubber sleeve 14 is provided on the outer wall of the movable rod 12 , and the spring 15 is located inside the rubber sleeve 14 . The rubber sleeve 14 can cover and protect the spring 15 .

[0027] like Figure 1and Figure 2 As shown, a second motor 5 is installed on the top of the mixing tank 1. The rotating shaft of the second motor 5 passes through the top of the mixing tank 1 and is fixedly connected to a rotating rod 9. A stirring blade 7 is installed on the outer wall of the rotating rod 9. After the second motor 5 is started, it can drive the rotating rod 9 and the stirring blade 7 to rotate in the mixing tank 1, thereby driving the concrete mortar and mortar admixture in the mixing tank 1 to be fully mixed.

[0028] According to the above technical scheme, the working steps of this scheme are summarized and sorted out: when the utility model is used, after the mortar admixture enters the feeding box 2 through the feeding hopper 3, the feeding roller 13 is driven to rotate by starting the first motor 4. When the feeding roller 13 rotates, the arc-shaped convex ridges can be used to close and open the bottom opening of the feeding box 2, so as to flexibly control the feeding state of the mortar admixture in the box. At the same time, the rotation of the feeding roller 13 can make the mortar admixture slide along the inclined surface 10.

[0029] When the movable rod 12 is in use, one end of the bottom of the movable rod 12 is in contact with the feeding roller 13. When the feeding roller 13 rotates, the curved ridges can be used to push the movable rod 12 upward. After the movable rod 12 passes through the curved ridges, the spring 15 provides a rebound force to lower the movable rod 12. When the feeding roller 13 rotates to feed the mortar admixture, the movable rod 12 is controlled to rotate up and down, thereby improving the smoothness of the mortar admixture entering the mixing tank 1, avoiding the mortar admixture from accumulating at the bottom opening of the feeding box 2 and being unable to fall, thereby ensuring uniform feeding.

Although the embodiments of the present invention have been shown and described, it is understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the attached claims and their equivalents.
