[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. The utility model improves loading and unloading efficiency by quickly dumping steel bars by rotating the steel bar pool. Specifically, when the rotating wheel rotates, the pull rope pulls the steel bar pool to move along the chute. When the first rotating rod moves to the top of the chute, the steel bar pool starts to rotate and dumps the steel bars toward the chute.

[0015] 2. The utility model uses a protective cover and an arc-shaped channel to avoid safety accidents when dumping steel bars. Specifically, the inclined platform is used to facilitate the dumping of steel bars, and the arc-shaped channel is used to limit the falling range of the steel bars when dumping them, so as to avoid the steel bars falling out of the chute and causing safety accidents. The protective cover is used to prevent the discarded steel bars in the pool from being directly flew out of the steel bar pool due to the centrifugal force when the steel bar pool rotates.

[0016] 3. The utility model uses an extendable and rotatable chute to adapt to different types of trucks and has strong versatility. Specifically, since the models of trucks are the same, in order to improve the versatility of the device, the connection angle between the chute and the truck compartment clamping plate is changed by the rotating shaft to facilitate the waste steel bars to fall into the car faster. The sub-plate extends the length of the chute through the positioning hole to further improve the versatility. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0024] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0025] See also Figure 1 to Figure 6As shown, a waste steel bar disposal device includes a loading rack 1 and a steel bar pool 7 installed on the loading rack 1 for loading waste steel bars and a chute 8 for delivering the waste steel bars to a truck. The loading rack 1 is provided with a rotating wheel 3 controlled by the traction force of the truck, a pull rope 4 connecting the rotating wheel 3 and the steel bar pool 7, and a first rotating rod 5 and a second rotating rod 6 serving as the movement fulcrum of the steel bar pool 7. The loading rack 1 is connected by two symmetrical side rods 2. The steel bar pool 7 is arranged between the two side rods 2 and can move up and down along the side rods 2. The chute 8 is rotatably arranged in the middle of the loading rack 1, the rotating wheel 3 is rotatably arranged on the top of the side rod 2, the pull rope 4 surrounds the steel bar pool 7 and the two ends of the pull rope 4 are wrapped around the two rotating wheels 3, the first rotating rod 5 is rotatably connected to the steel bar pool 7 and is located between the two side rods 2, and the second rotating rod 6 is rotatably connected to the steel bar pool 7 and is attached to the rod surface of the side rod 2.

[0026] Since most of the discarded steel bars are short steel bars with a length of 30 cm, the steel bar pool 7 is improved by using the conical reverse discharging concrete mixer feed hopper. The chute 8 is placed on the truck compartment plus deck. The wheel 3 is rotated by the traction force of the truck to pull the pull rope 4. The steel bar pool 7 is initially on the ground for convenient addition of discarded steel bars. With the action of the pull rope 4, it moves to the top of the side rod 2 of the upper material rack 1 through the first rotating rod 5. The second rotating rod 6 is used to support the steel bar pool 7 and keep it moving in a horizontal manner with the ground to prevent the steel bar pool 7 from falling due to its own gravity during the movement. When the first rotating rod 5 moves to the top of the side rod 2, the rotating wheel 3 continues to rotate. The steel bar pool 7 rotates with the first rotating rod 5 as the axis under the tension of the pull rope 4, and the discarded steel bars inside fall into the chute 8 and are transported to the truck compartment by the chute 8.

[0027] See also Figure 1 and Figure 2 As shown, the side bar 2 is provided with a cross bar 21, a reinforcing plate 22 and a reinforcing rib 23. The cross bar 21 is arranged on the side bar 2 horizontally with the ground, the reinforcing plate 22 is connected between the two cross bars 21, and the reinforcing rib 23 is arranged at the intersection of the cross bar 21 and the side bar 2.

[0028] The cross bar 21 is used to reinforce the supporting strength of the side bar 2 to prevent the loading rack 1 from falling apart. The reinforcing plate 22 is used to fix the two side bars 2 and further increase the firm connection between the cross bar 21 and the side bar 2 through the reinforcing ribs 23 to ensure that the loading rack 1 can stably support the steel bar pool 7 containing a large amount of discarded steel bars.

[0029] See also Figure 1~Figure 3 As shown, the first rotating rod 5 is provided with an engaging wheel 52 and a first bracket 53, and a slide groove 51 is provided on the opposite surfaces of the two side rods 2. The engaging wheel 52 is installed at both ends of the first rotating rod 5 and is in the slide groove 51. The first bracket 53 is rotatably connected to the first rotating rod 5 and fixed on the top of the steel bar pool 7.

[0030] The size of the interlocking wheel 52 corresponds to that of the slide 51. The first bracket 53 is used to connect the steel bar pool 7 and the first rotating rod 5. When the rotating wheel 3 rotates 1, the pull rope 4 pulls the steel bar pool 7 along the slide 51. When the first rotating rod 5 moves to the top of the slide 51, the steel bar pool 7 starts to rotate and dumps the steel bars toward the chute 8.

[0031] See also Figure 3 As shown, the second rotating rod 6 is provided with a roller 62 and a second bracket 63, the roller 62 is installed at both ends of the second rotating rod 6 and fits with the rod surface of the side rod 2, and the second bracket 63 is rotatably connected to the second rotating rod 6 and fixed to the bottom of the steel bar pool 7.

[0032] Since the steel bar pool 7 is heavy, moving up and down with the first rotating rod 5 as the fulcrum alone will cause rotation in advance. In order to ensure the smooth rise of the steel bar pool 7, the second rotating rod 6 is used to support the bottom of the steel bar pool 7 on the side rod 2. The second bracket 63 has the same principle as the first bracket 53.

[0033] See also Figure 1~Figure 5 As shown, an inclined platform 71, an arc-shaped channel 72 and a protective cover 73 are provided on the steel bar pool 7. The inclined platform 71 is installed above one end of the steel bar pool 7, the protective cover 73 is installed above the other end of the steel bar pool 7, and the arc-shaped channel 72 is provided in the inclined platform 71.

[0034] The inclined platform 71 is used to facilitate the dumping of steel bars, the arc channel 72 is used to limit the falling range of the steel bars when dumping them, to prevent the steel bars from falling out of the chute 8 and causing safety accidents, and the protective cover 73 is used to prevent the discarded steel bars in the pool from being directly flew out of the steel bar pool 7 due to the centrifugal force when the steel bar pool 7 rotates.

[0035] See also Figure 5 As shown, the surface of the steel bar pool 7 is provided with a connecting buckle 74, an axle wheel 75 and a rope buckle 76. The connecting buckle 74 is arranged at the connection between the protective cover 73 and the steel bar pool 7, two axle wheels 75 are installed on both sides of the steel bar pool 7, and the rope buckle 76 is installed at one end of the steel bar pool 7 and is located between the two axle wheels 75.

[0036] The connecting buckle 74 facilitates the quick installation and removal of the protective cover 73, thereby improving the efficiency of adding discarded steel bars to the steel bar pool 7. The rope buckle 76 and the shaft wheel 75 are passed through the pull rope 4 and hung on the rotating wheel 3 by the pull rope 4, ensuring that the rotating wheel 3 can lift the steel bar pool 7 through the fulcrum on the surface of the steel bar pool 7 when it rotates.

[0037] See also Figure 1 to Figure 6 As shown, a rotating shaft 81, a sub-plate 82 and a positioning hole 83 are provided on the chute 8. The rotating shaft 81 is installed at the notches on both sides of the chute 8. The sub-plate 82 is arranged in an array in the chute 8. The positioning hole 83 is arranged on the side walls of the chute 8 and the sub-plate 82.

[0038] Since all parts of the truck models are the same, in order to improve the versatility of the device, the connection angle between the chute 8 and the truck compartment clamping plate is changed by the rotating shaft 81 to facilitate the waste steel bars to fall into the vehicle faster. The sub-plate 82 extends the length of the chute 8 through the positioning hole 83 to further improve the versatility.

[0039] See also Figure 6 As shown, a latch 831 and a nut 832 are provided in the positioning hole 83 , the latch 831 passes through the positioning hole 83 from the inside of the chute 8 to the outside, and the nut 832 is installed on the latch 831 and is located outside the chute 8 .

[0040] The latch 831 and the nut 832 are used to quickly change the length of the chute 8. At the same time, the latch 831 is installed from the inside of the chute 8 to the outside to prevent the pin of the latch 831 from hindering the transportation of waste steel bars in the chute 8.

[0041] The above embodiments only express one or several implementation methods of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be based on the attached claims.
