[0012] The following is a detailed description of the embodiments of the present invention with reference to the accompanying drawings. DETAILED DESCRIPTION
[0013] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples provided are intended only to illustrate the present invention and are not intended to limit the scope of the present invention. The following paragraphs describe the present invention in more detail by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become more apparent from the following description. It should be noted that the drawings are all in a very simplified form and are not to exact proportions, and are only used to facilitate and clearly illustrate the embodiments of the present invention.
[0014] It should be noted that when a component is referred to as being "fixed to" another component, it may be directly on the other component or there may also be a central component. When a component is considered to be "connected to" another component, it may be directly connected to the other component or there may also be a central component. When a component is considered to be "set on" another component, it may be directly set on the other component or there may also be a central component. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.
[0015] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of this invention are intended only to describe specific embodiments and are not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments:
[0017] like Figure 1 As shown, a mortar liquid injector for anchor bar insertion includes a conveying plate 1, a through groove 2 for the anchor bar to pass through is opened inward on the outer edge of the conveying plate 1, and vertical plates 3 are provided on both sides of the through groove 2 on the conveying plate 1. A threaded rod 4 is passed through each vertical plate 3, and an adjusting nut 5 is tightened on both sides of the threaded rod 4 on the vertical plate 3. An arc-shaped limit plate 6 is fixed on the end of the threaded rod 4 facing the through groove 2, and a hole for the anchor bar to pass through is formed between the two arc-shaped limit plates 6. A slurry injection tube 7 is installed on the conveying plate 1, and the slurry injection tube 7 is connected to the slurry conveying pipeline. A conveying handle rod 8 is installed on the conveying plate 1.
[0018] When the present invention is used, the anchor bar can be inserted into the through groove 2, and then the position of the adjusting nut 5 can be changed to bring the arc-shaped limiting plate 6 close to the anchor bar, so that the conveying plate 1 can be conveyed along the anchor bar during transportation, and the position can be better determined. The position of the arc-shaped limiting plate 6 can be changed, and it can be adapted to anchor bars of different diameters.
[0019] The conveying plate 1 is a circular structure.
[0020] A plurality of balls 9 are provided on the inner side surface of the arc-shaped limiting plate 6 so that when the conveying plate 1 is placed into the anchor bar hole, the arc-shaped limiting plate 6 can move more smoothly along the anchor bar.
