[0039] The conveyor belt 1 includes a bracket and rollers installed on the bracket. A belt is installed on the rollers. The slope 2 includes an inclined plate. On both side edges of the inclined plate, inclined legs are provided. The two inclined legs are commonly fixed on the side surface of the bracket close to the feeding bed 5. The belt and the inclined plate are arranged with a gap; Through the above structural settings, the slope 2 and the conveyor belt 1 are fixedly connected, and at the same time, it is ensured that the ribbed steel bars conveyed from the belt can smoothly slide onto the slope 2.

[0040] The working principle is as follows:

[0041] The first step: By setting a slope 2 at the output end of the conveyor belt 1, the operator places the ribbed steel bars to be processed on the conveyor belt 1. The conveyor belt 1 conveys the ribbed steel bars to the position of the slope 2. A feeding bed 5 is provided below the slope 2. The ribbed steel bars fall onto the stop groove 6 of the feeding bed 5 through the slope 2. A slot 3 is opened on the feeding bed 5. The ribbed steel bars will be horizontally arranged on the slot 3;

[0042] Step 2: The first motor 9 drives the rotating rod 20 to rotate, and the rotating rod 20 drives the rotating frame 21 to rotate. A notch 227 is provided on the rotating frame 21, and the linkage rod 225 is connected to the rotating frame 21 in rotation in the notch 227. A side groove 224 is provided on the rotating frame 21 on one side of the linkage rod 225. The third motor 223 is provided in the side groove 224. The third motor 223 drives the small gear 22 in the notch 227 and the fan gear 226 on the linkage rod 225 to rotate. When the fan gear 226 rotates, it drives the linkage rod 225 to rotate, and the linkage rod 225 can swing slightly.

[0043] Step 3: A placing hand 23 is provided on the linkage rod 225. When the placing hand 23 moves to the position of the stop slot 6, it drags away a ribbed steel bar. The ribbed steel bar will rotate with the rotating frame 21, and the rotating frame 21 will rotate toward the placement slot 4 position of the feeding bed 5. When the rotating frame 21 moves to the placement slot 4 position, the placing hand 23 is driven by the third motor 223 to rotate, thereby throwing the ribbed steel bar out, and then transporting the ribbed steel bar to the placement slot 4;

[0044] Step 4: The second motor 17 drives the rotating plate 16 to make a circular motion, and the rotating plate 16 drives the connecting rod 15 to make a circular motion. When the connecting rod 15 rotates, it moves up and down in the vertical slot 14. When the connecting rod 15 rotates following the rotating plate 16, it drives the vertical plate 13 to move horizontally. When the vertical plate 13 moves horizontally, it drives the push rod 11 to move horizontally, so that the push rod 11 drives the push plate 7 to push the ribbed steel bars. The push plate 7 pushes the ribbed steel bars to the round head processing equipment position for processing, or the push plate 7 pushes the ribbed steel bars onto the straightening bed 24;

[0045] Step 5: When the ribbed steel bars pass through the front kick plate 31 and enter the pressing groove 25, the construction workers can press down the pressing plate 26 to straighten the ribbed steel bars in the pressing groove 25. When the straightening work is completed, the construction workers can press down the extrusion frame 35 with both hands to drive the front kick plate 31 upward. The side of the front kick plate 31 contacts the end of the ribbed steel bars and pops out the ribbed steel bars in the pressing groove 25. The popped-out ribbed steel bars are taken to the round head processing equipment for processing.

[0046] The present invention sets a slope 2 at the output end of the conveyor belt 1. The construction workers place the ribbed steel bars to be processed on the conveyor belt 1. The conveyor belt 1 transports the ribbed steel bars to the slope 2. The ribbed steel bars fall onto the feeding bed 5 through the slope 2. The feeding bed 5 is provided with a slot 3. The ribbed steel bars will be horizontal on the slot 3. The holding hand 23 can be rotated to drag away a ribbed steel bar, and the ribbed steel bar is rotated to the placement slot 4 position and transported to the placement slot 4. Then the second motor 17 drives the rotating plate 16 to make a circular motion. The rotating plate 16 drives the connecting rod 15 to make a circular motion. When the connecting rod 15 rotates, it moves up and down in the vertical slot 14. The connecting rod 15 When the rotating plate 16 rotates, it drives the vertical plate 13 to move horizontally. When the vertical plate 13 moves horizontally, it drives the push rod 11 to move horizontally, so that the push rod 11 drives the push plate 7 to push the ribbed steel bars to the position of the round head processing equipment, thereby realizing automatic loading of the ribbed steel bars; it solves the technical problem of high labor intensity of construction workers in traditional manual handling of ribbed steel bars. The construction workers only need to carry the ribbed steel bars to the conveyor belt 1, and there is no need to move back and forth to carry the ribbed steel bars. The transportation distance of the ribbed steel bars is shortened, the labor intensity of the construction workers is reduced, and the efficiency of the construction workers in carrying the ribbed steel bars is improved, thereby improving the efficiency of the round head processing of the ribbed steel bars.
