[0038] The following will be combined with the drawings of the specific embodiments of the utility model to clearly and completely describe the exemplary scheme of the utility model. Unless otherwise defined, the technical terms or scientific terms used in the utility model should be the common meanings understood by people with ordinary skills in the relevant field.

[0039] like Figure 1 As shown, the automatic feeding device of the grouting system of the anchor-injection machine of this embodiment includes a track bracket 1, a hydraulic motor 2, two wire rope reels 4, two pulley linkage mechanisms 6 and an angle-adjustable flap 7. The track bracket 1 is installed on the anchor-injection machine grouting system 5. The track bracket 1 is used to support the flap 7, the outer spherical bearing 11 and other components. A pair of tracks is opened on the track bracket 1. The hydraulic motor 2 is used to provide power. The hydraulic motor 2 is arranged on the upper part of the track bracket 1. The output end of the hydraulic motor 2 is connected to a transmission shaft 3. The hydraulic motor 2 can drive the transmission shaft 3 to rotate. The transmission shaft 3 is used to transmit power. Two wire rope reels 4 are arranged at the left and right ends of the transmission shaft 3. The transmission shaft 3 rotates together with the wire rope reels 4. The wire rope is wound on the wire rope reels 4. Preferably, the wire rope reels 4 use small gap reels to omit the wire rope wiring device. The two pulley linkage mechanisms 6 are respectively arranged at the ends of the two wire ropes and move up and down along the track of the track bracket 1. The flap 7 is rotatably connected to the two pulley-link mechanisms 6 , and is turned over and unloaded when at the top of the track bracket 1 .

[0040] The track bracket 1 is a symmetrical structure. The structure of one side is described below, and the structure of the other side is symmetrical to it. Figure 2 As shown, the track bracket 1 includes a vertical bending plate 101, which is used to provide a track for the movement of the flap 7. A support frame 102 is horizontally welded to the upper part of the vertical bending plate 101, and an upper mounting plate 103 is welded to the end of the support frame 102. At least two connecting plates 104 are welded to the lower part of the vertical bending plate 101, and two connecting plates 104 are used in this example. The vertical bending plate 101 is fixed to the grouting system 5 of the anchor-injection integrated machine through the upper mounting plate 103 and the two connecting plates 104. Preferably, through holes are opened on the upper mounting plate 103 and the two connecting plates 104, and bolts are passed through the through holes to achieve fastening.

[0041] A plurality of ribs 105 are arranged at the front and rear ends of the vertical bending plate 101 to improve the rigidity of the track bracket 1. A small column 106 is arranged vertically between the support frame 102 and the vertical bending plate 101, and the small column 106 and the support frame 102 are also used to improve the rigidity of the track bracket 1 to meet the bracket rigidity requirements.

[0042] The track bracket 1 is provided with four sets of symmetrical redirection pulley blocks, which are two sets of upper redirection pulley blocks and two sets of lower redirection pulley blocks. The two sets of redirection pulley blocks are used to realize the steering of the wire rope on one side of the track bracket 1. After the wire rope passes through the two sets of redirection pulley blocks, it drives the reciprocating motion of the pulley linkage mechanism 6. The upper redirection pulley block includes an upper pulley bracket 107 and an upper pulley 108 mounted on the upper pulley bracket 107. The upper pulley bracket 107 can be fixed to the support frame 102 by bolts. The lower redirection pulley block includes a lower pulley mounting plate 109 and a lower pulley bracket 110 fixed to the lower pulley mounting plate 109 by bolts. The lower pulley bracket 110 is provided with a lower pulley 111. The lower pulley mounting plate 109 can be fixed to the vertical bending plate 101 by bolts. Of course, according to actual needs, the positions of the upper and lower pulleys 111 can be adjusted by adjusting the angles of the upper pulley bracket 107 and the lower pulley bracket 110, so as to flexibly change the steering of the wire rope.

[0043] like Figure 5 and Figure 6 As shown, the hydraulic motor 2 is fixed on the anti-twist block 8, and the anti-twist block 8 is installed on the right vertical bending plate 101. Specifically, the anti-twist block 8 is an L-shaped plate. The hydraulic motor 2 is fixed to the vertical part of the anti-twist block 8 by bolts, and the horizontal part of the anti-twist block 8 is inserted into the mounting hole of the right vertical bending plate 101. A through hole is opened on the horizontal part, and a bolt is arranged in the through hole. The bolt is equipped with two nuts. The upper nut is welded to the right vertical bending plate 101, and the lower nut is used as a top nut to prevent the bolt from loosening. The bolt here serves as an axial positioning of the hydraulic motor 2 to prevent it from falling off the transmission shaft 3.

[0044] like Figure 5and Figure 6 As shown, the output end of the hydraulic motor 2 is connected to the transmission shaft 3 through a coupling 9 (a flat key can be used for the connection with the coupling 9). The coupling 9 is used for power transmission between the hydraulic motor 2 and the transmission shaft 3. Preferably, the coupling 9 is covered with a coupling shield 10 on the outside, and the coupling shield 10 is used to protect the internal coupling 9. An outer spherical bearing 11 is installed on the outside of the left and right vertical bending plates 101. The transmission shaft 3 is matched with the right outer spherical bearing 11 (interference fit can be used) and then passes through the right vertical bending plate 101. The end of the transmission shaft 3 passes through the left vertical bending plate 101 and matches with the left outer spherical bearing 11 (interference fit can be used). Supported by the left and right outer spherical bearings 11, the transmission shaft 3 can rotate freely under the drive of the hydraulic motor 2.

[0045] The pulley linkage 6 is used to connect the wire rope and the flap 7. Figure 3 As shown, the pulley-link mechanism 6 includes a connecting rod 601, and the upper and lower ends of the connecting rod 601 are provided with axles, namely an upper axle 602 and a lower axle 603, and the upper and lower axles are connected with load-bearing wheels 604 through bearings. A lifting ring 605 is provided on the upper axle 602, which is used to pass a steel wire rope, and the steel wire rope lifts the flap 7 to reciprocate. Under the lifting action of the steel wire rope, the upper and lower load-bearing wheels slide in the vertical bending plate 101. A mounting plate 607 is welded to the bottom of the connecting rod 601, and two nuts are welded to the bottom of the mounting plate 607, and an adjusting bolt 608 matched with the nut passes through the mounting plate 607 upward. The two adjusting bolts 608 are against the upper flap 7, and by adjusting the extension length of the adjusting bolts 608, the uneven angle of the flap caused by the assembly gap can be compensated.

[0046] like Figure 4 As shown, the flap 7 mainly plays a load-bearing role. The flap includes a rectangular frame composed of a square steel tube 701, an angle steel 702 and a flat steel 703. A panel 704 is welded on the top of the rectangular frame. Two blades 705 are arranged on the upper surface of the panel 704. Ear plates 706 are welded at both ends of the square steel tube 701. The ear plates 706 are provided with round holes 707. The lower wheel shaft 603 is inserted into the round holes. A locking nut 606 is arranged at the protruding end to achieve the connection between the flap 7 and the connecting rod 601. When the flap 7 is not in use, the flap 7 is folded up to save space.

[0047] Here’s how it works:

[0048] First, adjust the upward extension length of the adjusting bolt 608 to adjust the angle of the flap 7 so that the flap 7 remains horizontal, and place the filled packaging bag on the flap 7. Then start the hydraulic motor 2, which drives the transmission shaft 3 and the wire rope reel 4 to rotate together, the wire rope lifting connecting rod 601 rises, and the upper and lower load-bearing wheels slide upward in the vertical bending plate 101, thereby lifting the flap 7 and moving it upward together. When the flap 7 reaches the inclined section of the track bracket 1, the connecting rod 601 is twisted to drive the flap 7 to tilt at a certain angle, and the packaging bag slides downward under the action of gravity. During the sliding process, the blade 705 will cut the packaging bag, and the material falls into the grouting system 5, realizing automatic feeding of the grouting pump.

[0049] It should be noted that when one element is “connected”, “coupled” or “connected” to another element, it may mean that they are directly connected, coupled or connected, but it should be understood that there may be intermediate elements between the two; that is, the positional relationships of direct connection and indirect connection are covered.

[0050] It should be noted that the use of "a" or "an" and similar words does not necessarily indicate a quantitative limitation. "Include" or "comprising" and similar words mean that the elements or objects preceding the word include the elements or objects listed after the word and their equivalents, but do not exclude other elements or objects.

[0051] It should be noted that terms such as "up", "down", "left" and "right" indicating orientation or positional relationship are only used to indicate relative positional relationship. This is for the convenience of describing the present utility model, and does not mean that the device or element must have a specific orientation, be constructed and operated in a specific orientation. When the absolute position of the object being described changes, the relative positional relationship may also change accordingly.

[0052] The preferred embodiments for implementing the present invention have been described in detail above, but it should be understood that the role of these embodiments is only to exemplify, and is not intended to limit the scope, applicability or configuration of the present invention in any way. The protection scope of the present invention is defined by the attached claims and their equivalents.
