Description

Technical Field

[0001] This invention relates to the field of scrap steel bale technology, and in particular to a scrap steel bale vehicle. Background Technology

[0002] Steel scrap refers to the steel waste generated during the steel production process, as well as the steel materials in scrapped equipment and components. Usually, a special hydraulic baler is used to compress the loose steel scrap into rectangular bales, which facilitates transportation and recycling of the steel scrap for smelting, allowing the steel scrap to be reused.

[0003] A patent with publication number CN217671290U discloses a metal baling production line and a metal baling vehicle. This utility model integrates the shearing and removal of extra-long scrap steel pieces, improves the heat transfer, mass transfer, conduction, convection and radiation reaction conditions in the center of the baled block, facilitates the observation of internal components, and avoids the separation of fuel from scrap steel under high-speed airflow during fuel filling. It designs an integrated, mobile, modular production line for shearing, vibrating, drilling, fuel filling and baling of scrap steel.

[0004] The above solution uses hydraulic capping to pack scrap steel. However, the hydraulic capping equipment is large, which causes transportation problems. In addition, a gripping robotic arm is needed to remove the scrap steel bales from the compression and packing area before the next packing operation, which complicates the scrap steel packing process and reduces the efficiency of scrap steel packing.

[0010] In one embodiment of the present invention, the lower part of the ejector frame is provided with sliding structures on both sides of the sealing block. The sliding structure includes a slide rod fixed to one side of the ejector frame, a slider slidably connected to the slide rod, the slider slidably connected to the ejector frame, a first spring sleeved on one side of the slide rod near the slider, one end of the first spring fixed to the ejector frame, the other end of the first spring fixed to the slider, and the two sliders are jointly fixed to a sliding plate. The end of the sliding plate near the sealing block is set as an arc-shaped surface.

[0011] In one embodiment of the present invention, the two sliders are rotatably connected to a transmission roller, the transmission roller is rotatably connected to a slide plate, and a first motor is fixedly connected inside one of the sliders, the output end of the first motor being fixedly connected to the transmission roller.

[0012] In one embodiment of the present invention, the outer wall of the transmission roller is provided with multiple sets of spikes, and the slide plate is provided with multiple protective grooves that match the spikes.

[0013] In one embodiment of the present invention, two support plates are fixedly connected to one side of the ejector frame, and a protective cover is rotatably connected between the two support plates. A second motor is fixedly connected to one side of one of the support plates, and the output end of the second motor is fixedly connected to the protective cover.

[0014] In one embodiment of the present invention, lifting structures are provided on both sides of the sealing block. The lifting structure includes a fixed plate fixed to the upper side of the sealing block, a shovel block fixed to the lower side of the sealing block, a fixed rod fixed between the fixed plate and the shovel block, a lifting block slidably connected to the fixed rod, and a second spring sleeved on the fixed rod on one side of the lifting block.

[0018] 2. The scrap steel bale vehicle of the present invention, when cutting the compressed scrap steel bale, has the protective cover vertically parallel to the top ejection frame in the initial state, which can prevent metal fragments from flying and causing injury to nearby personnel when the sealing block cuts the scrap steel bale. When cutting scrap steel of different lengths, the second motor is started to rotate the protective cover from the vertical state to the horizontal state, so that the scrap steel of different lengths can be placed on the placement plate from the discharge port. Then the second cylinder is started to lower the sealing block to cut the scrap steel of different lengths. Then the first cylinder is started to push the cut scrap steel of the same length from the discharge port through the top pressing block, so that the scrap steel of the same length can be transported and smelted.

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments described are not intended to limit the present invention.

[0022] Reference Figures 1 to 5 As shown, a scrap steel bale cart of the present invention includes a car body 1, a hydraulic tank 2 fixedly installed on the car body 1, a first cylinder 4 fixedly connected inside the hydraulic tank 2, a top pressing block 5 fixedly connected to the output end of the first cylinder 4, a placement plate 8 fixedly connected to one side of the car body 1 located at the hydraulic tank 2, a left gathering block 6 rotatably connected to one side of the placement plate 8, a right gathering block 7 rotatably connected to the other side of the placement plate 8, a car plate 9 fixedly connected to one side of the car body 1, a plurality of pushing structures evenly arranged on both sides of the top surface of the car plate 9, the pushing structures being used to push the left gathering block 6 and the right gathering block 7 to gather, an ejection frame 3 fixedly connected to one side of the car plate 9 located at the placement plate 8, a second cylinder 10 fixedly connected inside the ejection frame 3, a sealing block 11 fixedly connected to the output end of the second cylinder 10, and an outlet 36 matching the sealing block 11 opened in the ejection frame 3.

[0023] Specifically, when baling scrap steel using a hydraulic capping baling device, a robotic arm that clamps the metal places the scrap steel into the baling slot. The hydraulic equipment pushes the cap plate to initially compress the scrap steel in the baling slot, and then the hydraulic pushing device in the baling slot compresses the scrap steel a second time to obtain a rectangular scrap steel bale. The robotic arm then removes the scrap steel bale from the baling slot for stacking, allowing the scrap steel bale to be transported and smelted. However, this type of capping hydraulic baling device is relatively large, which causes transportation inconvenience. It also requires a gripping robotic arm to remove the scrap steel bale from the compression baling area before the next baling operation, which complicates the scrap steel baling process and reduces the efficiency of scrap steel baling. In this scheme, when baling scrap steel, the left gathering block 6 and the right gathering block 7 are as follows: Figure 4 The diagram shows the horizontally open state. The gripping robotic arm can place scrap steel onto the left collecting block 6, right collecting block 7, and placement plate 8. A pushing structure then rotates the left collecting block 6 and right collecting block 7 from a horizontal position to a vertical position. Figure 2 As shown, at this time, the second cylinder 10 is in the extended state, causing the sealing block 11 to block the discharge port 36 of the ejector frame 3. This creates a sealed space with the sealing block 11, the left gathering block 6, the right gathering block 7, and the placement plate 8. Then, the first cylinder 4 is activated to push the pressing block 5, compressing the scrap steel in the left gathering block 6, the right gathering block 7, and the placement plate 8 into a block. Next, the second cylinder 10 is activated to retract, causing the sealing block 11 to move upwards and open the discharge port 36 of the ejector frame 3. The first cylinder 4 is then activated again to push the compressed scrap steel bale. The scrap steel bale can be pushed out of the placement plate 8. If the length of the scrap steel bale is too long, it can be cut off by the sealing block 11. After the scrap steel bale is completely pushed out of the placement plate 8, loose scrap steel can be put back into the placement plate 8 for baling. This reduces the space occupied by the baling equipment, making it easier to load and use. It can also cut off scrap steel bales that are too long to load and transport. The baled scrap steel bales can also be pushed out automatically, improving the efficiency of scrap steel baling and optimizing the scrap steel baling process.

[0024] like Figure 4 As shown, the pushing structure includes a fixed frame 12 fixed to one side of the vehicle plate 9, a third cylinder 13 fixed inside the fixed frame 12, a sliding frame 14 fixed to the output end of the third cylinder 13, a fourth cylinder 15 rotatably connected inside the sliding frame 14, the sliding frame 14 slidably connected to the vehicle body 1, and multiple fixed brackets 16 fixed to one side of both the left gathering block 6 and the right gathering block 7, with the output end of the fourth cylinder 15 rotatably connected to the fixed bracket 16.

[0025] Specifically, when using the jacking structure to push the left gathering block 6 and the right gathering block 7, the third cylinder 13 is activated to push the sliding frame 14, causing the fourth cylinders 15 on both sides to move to both sides. The fourth cylinder 15 is activated to push the fixing frame 16, thereby pushing the left gathering block 6 and the right gathering block 7, so that the left gathering block 6 and the right gathering block 7 rotate from the horizontal open state to the vertical gathered state. The left gathering block 6 and the right gathering block 7 can also be rotated by adjusting the third cylinder 13 and the fourth cylinder 15 on the same side, so that the scrap steel material overflowing from the left gathering block 6 and the right gathering block 7 is compressed and packed into the left gathering block 6 and the right gathering block 7 by folding left and right.

[0026] like Figure 5 As shown, the inner two side walls of the right gathering block 7 are two vertical surfaces. The outer wall of the right gathering block 7 near the placement plate 8 is a straight surface, and the outer wall of the right gathering block 7 away from the placement plate 8 is an arc-shaped surface. The part of the left gathering block 6 near the placement plate 8 is a straight surface, and the part of the left gathering block 6 away from the placement plate 8 is an arc-shaped structure.

[0027] Specifically, when the left gathering block 6 and the right gathering block 7 are gathered together, the straight surfaces of the left gathering block 6 and the right gathering block 7 can form a square enclosed space with the placement plate 8 and the top frame 3, which can compress the scrap steel bale into a square shape for easy transportation. The curved surfaces of the left gathering block 6 and the right gathering block 7 can cut off the excess scrap steel that overflows from the left gathering block 6 and the right gathering block 7, so that the scrap steel can be better packaged into a regular square scrap steel bale for easy transportation.

[0028] like Figure 6 and Figure 7 As shown, the lower part of the ejector frame 3 is provided with sliding structures on both sides of the sealing block 11. The sliding structure includes a slide rod 17 fixed to one side of the ejector frame 3, a slider 19 slidably connected to the slide rod 17, the slider 19 slidably connected to the ejector frame 3, a first spring 18 sleeved on one side of the slide rod 17 and the first spring 18 fixed to the ejector frame 3, the other end of the first spring 18 fixed to the slider 19, and the two sliders 19 are jointly fixed to a slide plate 31. The end of the slide plate 31 near the sealing block 11 is set as an arc surface.

[0029] Specifically, when the scrap steel bale is cut off by the sealing block 11, the scrap steel bale is pushed out of the placement plate 8. The second cylinder 10 is activated to push the sealing block 11 downward to cut off the scrap steel bale. When the scrap steel bale is completely cut off, it will press against the arc surface of the sliding plate 31 to make the sliding plate 31 move. The sliding plate 31 causes the slider 19 to move on the sliding rod 17 and inside the ejection frame 3 and stretch the first spring 18, so that the scrap steel bale can be smoothly cut off and pushed out of the ejection frame 3.

[0030] like Figure 7As shown, two sliders 19 are rotatably connected to a transmission roller 21, and the transmission roller 21 is rotatably connected to a slide plate 31. A first motor 23 is fixedly connected inside one of the sliders 19, and the output end of the first motor 23 is fixedly connected to the transmission roller 21.

[0031] Specifically, after the scrap steel bale is cut off by the sealing block 11, the first motor 23 is started to make the transmission roller 21 rotate, which can convey the cut scrap steel bale out of the slide plate 31 and the ejection frame 3, preventing the scrap steel bale from accumulating on the slide plate 31.

[0032] like Figure 8 As shown, the outer wall of the transmission roller 21 is provided with multiple sets of spikes, and the slide plate 31 is provided with multiple protective grooves 32 that match the spikes.

[0033] Specifically, when the drive roller 21 rotates to pass the scrap steel bale out of the slide plate 31, the drive roller 21 with spikes can better convey the scrap steel bale, and the protective groove 32 prevents the scrap steel from getting tangled and remaining on the drive roller 21, ensuring that the drive roller 21 can normally pass the scrap steel bale out of the slide plate 31 and the ejector frame 3.

[0034] Example 2 like Figure 1 As shown in the first embodiment, another embodiment of the present invention is as follows: two support plates 33 are fixedly connected to one side of the ejector frame 3, and a protective cover 35 is rotatably connected between the two support plates 33. A second motor 34 is fixedly connected to one side of one support plate 33, and the output end of the second motor 34 is fixedly connected to the protective cover 35.

[0035] Specifically, when transporting scrap steel of varying lengths, the loading space cannot be fully utilized due to the different lengths of the scrap steel, leaving many gaps in the loading space. This results in unstable stacking of scrap steel and affects the efficiency of transporting scrap steel. When cutting the compressed scrap steel bale, the protective cover 35 is initially vertical and parallel to the ejector frame 3. This prevents metal fragments from flying and injuring nearby personnel when the sealing block 11 cuts the scrap steel bale. When cutting scrap steel of different lengths, the second motor 34 is started to rotate the protective cover 35 from the vertical state to the horizontal state, so that the scrap steel of different lengths can be placed on the placement plate 8 from the discharge port 36. Then, the second cylinder 10 is started to lower the sealing block 11 to cut the scrap steel of different lengths. Then, the first cylinder 4 is started to push the cut scrap steel of the same length from the discharge port 36 through the top pressing block 5, so that the scrap steel of the same length can be transported and smelted.

[0036] like Figure 6 and Figure 7As shown, both sides of the sealing block 11 are provided with lifting structures. The lifting structure includes a fixed plate 24 fixed to the upper side of the sealing block 11, a shovel block 28 fixed to the lower side of the sealing block 11, a fixed rod 25 fixed between the fixed plate 24 and the shovel block 28, a lifting block 27 slidably connected to the fixed rod 25, a second spring 26 sleeved on the fixed rod 25 on one side of the lifting block 27, one end of the second spring 26 fixed to the fixed plate 24, the other end of the second spring 26 fixed to the lifting block 27, and a roller 30 rotatably connected between the two lifting blocks 27.

[0037] Specifically, when cutting scrap steel of varying lengths, the sealing block 11 moves downward, causing the lifting structure to move downward. The roller 30 presses against the scrap steel placed on the slide plate 31 and the transmission roller 21. As the sealing block 11 continues to move downward, the lifting block 27 slides on the fixed rod 25, compressing the second spring 26. Then, the first motor 23 is started to rotate the transmission roller 21, which transmits the excess scrap steel after cutting out of the ejection frame 3, preventing the excess scrap steel from accumulating and blocking the discharge port 36.

[0038] like Figure 7 and Figure 8 As shown, protective plates 20 are fixed to both sides of the two sliders 19, and multiple protective plates 20 are slidably connected to the ejector frame 3. Protective plates 29 are fixed to one side of the two lifting blocks 27, and the two protective plates 29 are slidably connected to the ejector frame 3. The ejector frame 3 has grooves that match the protective plates 20 and 29 respectively.

[0039] Specifically, when cutting scrap steel, the slider 19 drives the protective plate 20 to slide within the ejection frame 3. The sliding of the protective plate 20 prevents metal fragments from falling into the ejection frame 3 and damaging or jamming the first spring 18, thereby ensuring the normal extension and retraction function of the first spring 18. The lifting block 27 drives the protective plate 29 to move within the limiting groove 22. The sliding of the protective plate 29 prevents metal fragments from falling into the limiting groove 22 and damaging or jamming the second spring 26, thereby ensuring the normal extension and retraction function of the protective plate 29.

[0040] like Figure 6 and Figure 7 As shown, the top frame 3 has limit grooves 22 on both sides that match the lifting structure. Both fixed plates 24 are slidably connected to the limit grooves 22. The bottom surfaces of both shovel blocks 28 are set as inclined surfaces. Both shovel blocks 28 are slidably connected to the limit grooves 22.

[0041] Specifically, when the lifting structure moves, the shovel block 28 set on the inclined surface can remove the metal fragments that have broken into the limiting groove 22, preventing the metal fragments from accumulating in the limiting groove 22 and affecting the movement of the lifting structure.

[0042] Working principle: In this scheme, when baling scrap steel, the left gathering block 6 and the right gathering block 7, as... Figure 4The diagram shows the horizontally open state. The gripping robotic arm can place scrap steel onto the left collecting block 6, right collecting block 7, and placement plate 8. A pushing structure then rotates the left collecting block 6 and right collecting block 7 from a horizontal position to a vertical position. Figure 2 As shown, at this time, the second cylinder 10 is in the extended state, causing the sealing block 11 to block the discharge port 36 of the ejector frame 3. In this way, the sealing block 11, the left gathering block 6, the right gathering block 7 and the placement plate 8 form a sealed space. At this time, the first cylinder 4 is activated to push the pressing block 5, which compresses the scrap steel in the left gathering block 6, the right gathering block 7 and the placement plate 8 into a block. At this time, the second cylinder 10 is activated to retract, causing the sealing block 11 to move upward and open the discharge port 36 of the ejector frame 3. The first cylinder 4 is activated again to push the compressed scrap steel bale, which can push the scrap steel bale out of the placement plate 8. If the length of the scrap steel bale is too long, it can also be cut off by the sealing block 11. After the scrap steel bale is completely removed from the placement plate 8, loose scrap steel can be put back into the placement plate 8 for baling. The third cylinder 13 is activated to push the sliding frame 14, causing the fourth cylinder on both sides to... Cylinder 15 moves to both sides, activating the fourth cylinder 15 to push the fixing frame 16, thereby pushing the left gathering block 6 and the right gathering block 7, causing the left gathering block 6 and the right gathering block 7 to rotate from a horizontally open state to a vertically gathered state. The left gathering block 6 and the right gathering block 7 can also be rotated by adjusting the third cylinder 13 and the fourth cylinder 15 on the same side, thereby compressing and baling the scrap steel material that overflows from the left gathering block 6 and the right gathering block 7 by folding it left and right. The straight surfaces of the left gathering block 6 and the right gathering block 7 can form a square sealed space with the placement plate 8 and the ejection frame 3, which can compress the scrap steel bale into a square shape for easy transportation. The arc-shaped surfaces of the left gathering block 6 and the right gathering block 7 can cut off the excess scrap steel material that overflows from the left gathering block 6 and the right gathering block 7, so that the scrap steel material can be better packaged into a regular square scrap steel bale for easy transportation. When the scrap steel bale is cut by the sealing block 11, it is pushed out of the placement plate 8. The second cylinder 10 is activated to push the sealing block 11 downwards, cutting the scrap steel bale. When the scrap steel bale is completely cut, it will press against the arc-shaped surface of the sliding plate 31, causing the sliding plate 31 to move. The sliding plate 31 causes the slider 19 to move on the sliding rod 17 and within the ejection frame 3, stretching the first spring 18, thus allowing the scrap steel bale to be smoothly cut and pushed out of the ejection frame 3. After the scrap steel bale is loaded, the first motor 23 is started to rotate the transmission roller 21, which will convey the cut scrap steel bale out of the slide plate 31 and the ejector frame 3, preventing the scrap steel bale from accumulating on the slide plate 31. When the transmission roller 21 rotates and conveys the scrap steel bale out of the slide plate 31, the transmission roller 21 with spikes can convey the scrap steel bale better. The protective groove 32 prevents the scrap steel from getting tangled and remaining on the transmission roller 21, ensuring that the transmission roller 21 can normally convey the scrap steel bale out of the slide plate 31 and the ejector frame 3. When cutting the compressed scrap steel bale, the protective cover 35 is initially vertical and parallel to the ejector frame 3. This prevents metal fragments from flying and injuring nearby personnel when the sealing block 11 cuts the scrap steel bale. When cutting scrap steel of different lengths, the second motor 34 is activated to rotate the protective cover 35 from a vertical position to a horizontal position, allowing the scrap steel of different lengths to be placed on the placement plate 8 from the discharge port 36. Then, the second cylinder 10 is activated to lower the sealing block 11 to cut the scrap steel of different lengths. The first cylinder 4 is then activated to push the cut scrap steel of uniform length from the discharge port 36 through the pressing block 5, allowing the uniformly cut scrap steel to be transported and smelted. When cutting scrap steel of different lengths, the sealing block 11 moves downward, causing the lifting structure to move downward. The roller 30 presses against the scrap steel placed on the sliding plate 31 and the transmission roller 21. The sealing block 11 continues to move downward. The movement causes the lifting block 27 to slide on the fixed rod 25, compressing the second spring 26. Then, the first motor 23 is started, causing the transmission roller 21 to rotate and convey the excess scrap steel after cutting out of the ejection frame 3, preventing the excess scrap steel from accumulating and blocking the discharge port 36. The slider 19 drives the protective plate 20 to slide within the ejection frame 3. The sliding of the protective plate 20 prevents metal fragments from falling into the ejection frame 3 and damaging or jamming the first spring 18, thus ensuring the normal extension and retraction function of the first spring 18. The lifting block 27 drives the protective plate 29 to move within the limiting groove 22. The sliding of the protective plate 29 prevents metal fragments from falling into the limiting groove 22 and damaging or jamming the second spring 26, thus ensuring the normal extension and retraction function of the protective plate 29. The shovel block 28 set on the inclined surface can remove the metal fragments that have fallen into the limiting groove 22, preventing the metal fragments from accumulating in the limiting groove 22 and affecting the movement of the lifting structure.

[0043] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
