The specific contents are as follows:

[0020] 1. By setting a buffer component, when the main body crushes the reinforced concrete, the crushed debris falls into the inside of the collection box through the bottom of the main body. At the same time, buffer components and buffer plates are installed on the four sides and bottom of the collection box. After the debris falls into the collection box, the debris will impact the buffer plate, so that the buffer plate moves after being subjected to the impact force.

At the same time, the buffer component 11 can buffer the impact force exerted on the collection box 3, thereby reducing the damage to the collection box 3 and improving the service life of the collection box 3. At the same time, the buffer component 11 and the buffer plate 12 are installed around and on the bottom of the collection box 3. At the same time, the main body 1 is a jaw crusher in the prior art, model PE400*600, and the pulley 2 is also the prior art. At the same time, the pulley 2 itself has a self-locking function.

[0031] One side surface of the sliding block 1103 is fixedly connected with a damping spring 1104, and the side surface of the damping spring 1104 away from the sliding block 1103 is fixedly connected to the sliding groove 1102, and the middle of the surface of the sliding block 1103 is rotatably connected to a movable rod 1105, and the top surface of the movable rod 1105 is rotatably connected to a stabilizing block 1106, and the top surface of the stabilizing block 1106 is fixedly connected to a connecting plate 1107, and telescopic rods 1108 are symmetrically installed on both sides of the bottom surface of the connecting plate 1107, and the surface of the telescopic rod 1108 is sleeved with a second spring 1109, and the bottom surface of the second spring 1109 is fixedly connected to the connecting block 1101, and the top surface of the second spring 1109 is fixedly connected to the connecting plate 1107, and the bottom surface of the telescopic rod 1108 is fixedly connected to the connecting block 1101, and the top surface of the connecting block 1101 is symmetrically provided with movable grooves 1110, and the movable grooves 1110 are slidably connected to the movable rod 1105, as shown in FIG. Figure 5 、 6As shown, the movement of the buffer plate 12 drives the movement of the connecting plate 1107, and the movement of the connecting plate 1107 drives the movement of the stabilizing block 1106. The movement of the stabilizing block 1106 drives the movement of the movable rod 1105. The movement of the movable rod 1105 pushes the sliding block 1103 to both sides. At the same time, when the sliding block 1103 moves, it squeezes the damping spring 1104, thereby deforming the damping spring 1104. At the same time, when the connecting plate 1107 descends, it squeezes the telescopic rod 1108 and the second spring 1109, thereby This causes the telescopic rod 1108 and the second spring 1109 to deform, and the elastic force of the damping spring 1104 is relatively large. At the same time, the sliding groove 1102 is limited, so that the damping spring 1104 will not swing significantly when it rebounds. At the same time, the second spring 1109 is a compression spring in the prior art. The second spring 1109 is limited by the telescopic rod 1108, so that the second spring 1109 will not swing significantly when it rebounds. Therefore, through the cooperation between the damping spring 1104, the telescopic rod 1108 and the second spring 1109, the buffer plate 12 can be buffered.

[0032] A limiting groove 7 is provided in the middle of the surface of the slider 6 near the slide groove 5. The limiting groove 7 is internally engaged with a limiting rod 8. The limiting rod 8 is away from the limiting groove 7 and passes through the surface of one side of the body 1 and is sleeved with a first spring 9. One side surface of the first spring 9 is fixedly connected to the limiting rod 8, and the other side surface of the first spring 9 is fixedly connected to the body 1. Figure 4 As shown, by pulling the limit rod 8 to separate the limit rod 8 from the limit groove 7, by pulling the collection box 3, the collection box 3 drives the slider 6 to slide inside the slide groove 5, so that the collection box 3 can be taken out. When installing the collection box 3, after placing the slider 6 inside the slide groove 5 and pushing the collection box 3 to a certain position, the limit rod 8 is loosened, so that the limit rod 8 returns to its original position under the action of the first spring 9, so that the limit rod 8 and the limit groove 7 are re-engaged together, thereby completing the installation of the collection box 3. At the same time, the first spring 9 is a tension spring in the prior art.

[0033] The top surface of the connecting plate 1107 is fixedly connected with a buffer plate 12. Figure 5 As shown, the buffer plate 12 is made of rubber, so that the buffer plate 12 itself has a certain buffering function, so that it can better buffer the impact force generated by debris falling into the collection box 3, thereby reducing damage to the collection box 3 and increasing the service life of the collection box 3.

[0034] Working principle: Before using this kind of steel bar recovery equipment for reinforced concrete columns, it is necessary to check the overall condition of the device to ensure that it can work normally. Figure 1 - Figure 6 As shown, first, when the main body 1 crushes the reinforced concrete, the crushed debris falls into the interior of the collection box 3 through the bottom of the main body 1. At the same time, buffer components 11 and buffer plates 12 are installed around and on the bottom of the collection box 3. After the debris falls into the collection box 3, the debris will impact the buffer plate 12, so that the buffer plate 12 moves after being subjected to the impact force. The movement of the buffer plate 12 will drive the movement of the connecting plate 1107, and the movement of the connecting plate 1107 will drive the movement of the stabilizing block 1106. The movement of the stabilizing block 1106 can drive the movement of the movable rod 1105. The movement of the movable rod 1105 will push the sliding block 1103 to both sides. At the same time, when the sliding block 1103 moves, it will squeeze the damping spring 1104, so that the damping spring 1104 is deformed. At the same time, when the connecting plate 1107 drops, it will push the telescopic rod 1108 and The second spring 1109 is squeezed, so that the telescopic rod 1108 and the second spring 1109 are deformed. At the same time, the elastic force of the damping spring 1104 is large. At the same time, the sliding groove 1102 is used to limit the damping spring 1104 when it rebounds. The second spring 1109 is a compression spring in the prior art. The second spring 1109 is limited by the telescopic rod 1108, so that the second spring 1109 will not swing significantly when it rebounds. Therefore, through the cooperation between the damping spring 1104, the telescopic rod 1108 and the second spring 1109, the buffer plate 12 can be buffered. At the same time, the buffer plate 12 is made of rubber, so that the buffer plate 12 itself has a certain buffering function, so that it can better buffer the impact force generated by debris falling into the collection box 3, thereby reducing damage to the collection box 3 and thus increasing the service life of the collection box 3.

[0035] Secondly, when it is necessary to clean the debris inside the collection box 3, the limit rod 8 is pulled to separate the limit rod 8 from the limit groove 7, and then the collection box 3 is pulled so that the collection box 3 drives the slider 6 to slide inside the slide groove 5, so that the collection box 3 can be taken out. When installing the collection box 3, after placing the slider 6 inside the slide groove 5 and pushing the collection box 3 to a certain position, the limit rod 8 is loosened so that the limit rod 8 returns to its original position under the action of the first spring 9, so that the limit rod 8 and the limit groove 7 are re-engaged together, thereby completing the installation of the collection box 3.

[0036] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
