[0023] Preferably, third hydraulic cylinders 40 are respectively provided at the bottom ends of the first support rod 34 and the second support rod 78. The piston rods of the third hydraulic cylinders 40 are connected to a support frame 41. A positioning cone 42 is provided on the bottom surface of the support frame 41.

[0024] Preferably, a water tank 22 is provided on the top surface of the cross beam 25. The output end of the water tank 22 is connected to a water pump 23.

[0025] Preferably, both the first clamping ring 2 and the second clamping ring 4 are of hollow structures, and long strip-shaped through grooves are opened on the inner side surfaces of the first clamping ring 2 and the second clamping ring 4. The long strip-shaped through groove of the second clamping ring 4 communicates with the material passing port 3. After the binding steel wires penetrate into the material passing port 3 of the second clamping ring 4, they are located in the long strip-shaped through groove. The long strip-shaped through groove is used for positioning the binding steel wires to prevent deviation.

[0026] Preferably, the handle 13 is of a U-shaped structure, and a through hole matching the insertion rod 18 is opened on the handle 13.

[0027] Preferably, a U-shaped grip 39 is provided on the outer side surface of the first support rod 34. The U-shaped grip and the insertion rod 18 are used for integrally moving the portal frame composed of the first support rod 34, the second support rod 78 and the cross beam 25.

[0028] During the steel bar bundling operation, first adjust the distance between the first support rod 34 and the second support rod 78 according to the site where the steel bars are scattered. Start the fourth motor 33 to drive the fourth gear 32 to rotate. The fourth gear 32 meshes with the fourth rack 31 and moves along the sliding grooves 251 on both sides of the cross beam 25 through the fourth sliding tube 30, thereby driving the first support rod 34 to move horizontally along the cross beam 25 to achieve the adjustment of the distance between the first support rod 34 and the second support rod 78. Place the first support rod 34 and the second support rod 78 on the ground. The first support rod 34 and the second support rod 78 can be inserted into the ground by the positioning cones 42 pushed by the third hydraulic cylinders 40 at the bottom ends to improve the reliability of the positioning of the first support rod 34 and the second support rod 78.

[0029] Start the second motor 21 to drive the second gear 20 to rotate. The second gear 20 meshes with the second rack 58 and drives the support box 49 to lift and lower along the second sliding rail 59 through the third sliding tube 19. The lifting and lowering of the support box 49 drives the lifting and lowering of the clamping plate 51. The opening and closing of the clamping plate 51 are controlled by the fifth motor 43 and the sixth motor 46. Stack the scattered steel bars under the clamping plate 51. Drive the clamping plate 51 to open and hold the outer ring of the stacked steel bars by the fifth motor 43 and the sixth motor 46, and then drive the clamping plate 51 to close by the fifth motor 43 and the sixth motor 46, thereby gathering the stacked steel bars and gathering the scattered steel bars in the clamping plate 51. During this process, the water pump 22 can be started to inject water into the clamping plate 51 through the hose 24. The clamping plate 51 sprays water on the gathered steel bars through the nozzles on the inner arc surface; at the same time, start the refrigerator in the support box 49. The refrigerator cools the water in the gaps between the steel bars to freeze, thereby temporarily fixing the gathered steel bars by freezing; repeat the above operations so that the steel bars are temporarily fixed by spraying water and freezing at at least three positions within the full length range.

[0030] Start the third motor 26 to drive the third gear 27 to rotate. The third gear 27 meshes with the third rack 28 and drives the second hydraulic cylinder 37 and the tapered rod 38 to lift and lower along the first sliding rail 29 through the fifth sliding tube 35 to the end face of the steel bar bundle. Start the second hydraulic cylinder 37 to push the tapered rod 38 so that the tapered rod 38 is inserted into the end face of the preliminarily fixed steel bar bundle; then drive the second hydraulic cylinder 37 and the tapered rod 38 to lift by the third motor 26 to lift the end face of the steel bar bundle.

[0031] Then the operator holds the handle 13 and starts the first motor 8 to drive the first gear 7 to rotate. The first gear 7 meshes with the first rack 11, thereby driving the first sliding tube 10 to move along the sliding rod 12, causing the first clamping ring 2 and the second clamping ring 4 to open. The first clamping ring 2 and the second clamping ring 4 are moved to both sides of the steel bar bundle through the connecting rope 15 and are located at the temporarily fixed position of the steel bar bundle without being sprayed with water and frozen. After moving into place, the through hole of the handle 13 is inserted into the insertion rod 18 to play a role in positioning the first clamping ring 2. The first motor 8 is controlled to close the first clamping ring 2 and the second clamping ring 4 and clamp them around the outer circle of the steel bar bundle. The seventh motor 69 is started to drive the turntable 70 to rotate, and the binding wire on the turntable 70 is released. The binding wire passes through the guide tube 73, the hollow shaft rod 71 and the material passing port 3 and penetrates into the second clamping ring 4, and returns to the other material passing port 3 of the second clamping ring 4 along the long strip-shaped through groove on the inner side surfaces of the second clamping ring 4 and the first clamping ring 2, that is, the binding wire surrounds the outer circle of the steel bar bundle for one week. The binding wire passing out of the material passing port 3 is placed in the mounting frame 64 and is temporarily fixed between the spaced-apart clamping plates 65. During the process of releasing the binding wire, the eighth motor 75 drives the runner 60 to rotate, and the runner 60 plays a role in guiding and conveying the binding wire. The first hydraulic cylinder 5 is started, and the guide tube 73 is pulled back through the positioning tube 68. At the same time, the turntable 70 is driven by the seventh motor 69 to rotate in the reverse direction to tighten the binding wire. Two fourth hydraulic cylinders 61 are started to make the clamping plates 65 at the top of the piston rod 63 clamp the head end and the tail end of the binding wire surrounding the steel bar bundle. At this time, the bolt between the fifth connecting rod 67 and the mounting frame 64 is loosened, and the mounting frame 64 is rotated with the hollow shaft rod 71 as the rotation axis, so as to tighten the head end and the tail end of the binding wire together. The tail end of the binding wire is cut off with scissors to realize the bundling of the steel bars. The above operations are repeated to bundle the binding wire at at least three positions within the full length of the steel bars.

[0032] In this steel bar bundling machine, the front part and the rear part of the connecting rope are two independent parts, which are flexibly connected by the connecting rope and are used separately. The front part strengthens the steel bar bundle through freezing, and the rear part bundles the steel bar bundle with steel wire. When the first clamping ring and the second clamping ring at the rear part of the connecting rope move to both sides of the steel bar bundle, the connecting frame can be placed flat on the ground, and the connecting rope has a certain length.

[0033] This steel bar bundling machine can gather scattered steel bars through the setting of the clamping plate, realizing the collection of steel bars and providing assistance for the bundling of steel bars. Through the cooperation of the water pump and the refrigerator in the support box, it is convenient to preliminarily fix the steel bars in an ice freezing manner before bundling, so that the scattered steel bars can be fastened with ice when collected together. Through the control of the tapered rod, the second hydraulic cylinder and the third motor, the tapered rod can be inserted into the steel bar bundle positioned by ice to lift the steel bars, providing convenience for the subsequent bundling of steel bars. Through the cooperation of the insertion rod and the handle, the handle can be inserted on the insertion rod to facilitate the movement of the device. By setting up the bundling mechanism, the steel wire is bundled outside the steel bar bundle by using the bundling mechanism to realize the bundling of steel bars.
