Description

Technical Field

[0001] This invention relates to the field of hydraulic baling machine technology, specifically a mobile tire hydraulic baling machine. Background Technology

[0002] As a core component of mobile equipment such as automobiles and construction machinery, tires have seen their annual consumption rise year by year with the rapid development of the transportation industry, resulting in an explosive growth in the number of waste tires. The rubber material of waste tires has extremely strong resistance to degradation, taking hundreds of years to decompose naturally. Indiscriminate dumping not only occupies a large amount of land resources but also may spontaneously combust due to long-term compression and high-temperature exposure, releasing toxic gases such as hydrogen sulfide and dioxins, causing serious pollution to the atmosphere, soil, and water sources. Therefore, how to efficiently process waste tires and achieve their reduction and resource utilization has become an urgent task for the environmental protection industry. Tire hydraulic balers use hydraulic power to compress loose waste tires into compact blocks, reducing the tire volume to 1 / 3-1 / 5 of its original volume, significantly reducing transportation costs and facilitating subsequent recycling into recycled rubber, tire powder, and asphalt modifiers. It is a key piece of equipment in the waste tire recycling and processing industry chain.

[0003] In existing technologies, traditional tire hydraulic balers are mostly designed for fixed workstations, requiring operation in factory buildings or fixed sites. They cannot be flexibly moved to waste tire generating sites (such as auto repair shops, scrap vehicle dismantling plants, and highway maintenance stations), resulting in waste tires needing to be transported to the baling site first, increasing intermediate costs. Although some mobile balers are equipped with walking mechanisms, their lifting and tilting systems have design flaws. For example, using single-acting lifting cylinders results in insufficient lifting force and an inability to achieve precise control. The tilting angle is usually no more than 90°, requiring manual assistance to push the tires during feeding, increasing operational risks. In addition, the compression chambers of existing equipment are mostly rectangular rigid structures, which have poor tire containment. During compression, the tires tend to expand outwards, resulting in uneven density and loose, easily scattered baled blocks, affecting subsequent stacking and transportation efficiency. Some balers also use conventional valve group control for their hydraulic systems, which have slow response speeds and low pressure regulation accuracy, resulting in long compression cycles and operational efficiency that cannot meet the needs of large-scale processing. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this invention provides a mobile tire hydraulic baler. By optimizing the walking mechanism, the equipment achieves flexible mobility and can be directly deployed to waste tire generating sites such as auto repair shops and scrap vehicle dismantling plants, reducing intermediate transportation links. An anti-rebound mechanism is added to the compression chamber to improve tire wrapping and compression tightness. Simultaneously, the cylinder design and hydraulic valve group control scheme of the lifting and tilting system are improved. This solves the technical problems of traditional fixed-station balers requiring waste tire transportation, increasing costs; insufficient lifting force in some mobile balers with tilting angles not exceeding 90° requiring manual feeding; uneven density and looseness of the baled blocks due to the rectangular rigid structure of the compression chamber; and slow hydraulic system response and low pressure adjustment accuracy leading to long compression cycles and low operating efficiency.

[0017] (III) Beneficial Effects

[0018] Compared with the prior art, the present invention provides a mobile tire hydraulic baler, which has the following advantages:

[0019] 1. The compression mechanism adopts a structural design with the compression cylinder set in the center and symmetrical connecting rods on both sides, so that the compression plate always remains horizontal during the up and down movement. This ensures that the compression plate is evenly stressed during the up and down movement, avoids tilting or offset, effectively improves the density and consistency of tire compression, and ensures that the packaged tire blocks are regular in shape and easy to stack and transport.

[0020] 2. The addition of an anti-rebound mechanism to the compression chamber improves the wrapping effect on the tires and the compactness after compression, further ensuring that the packaged tire blocks are regular in shape and not easily loosened. This effectively solves the problems of difficult binding and unstable stacking caused by tire rebound in traditional baling machines, and significantly improves the efficiency of subsequent transportation and storage.

[0021] 3. The lifting cylinder adopts a double-acting hydraulic cylinder and is connected to the middle of the tilting mechanism. With the first tilting support and the second tilting support plug-in hinge structure, it not only ensures the support strength during tilting, but also makes the tilting action of the tire packing device more stable and controllable, enhances the adaptability of the equipment to different sites, facilitates the rapid unloading of the packed tires, reduces manual assistance time, and improves work efficiency.

[0038] Please see Figure 3 The mobile frame 1 includes a main frame 101. Three support legs 102 and eight tires 103 are mounted on the bottom of the main frame 101. The three support legs 102 are located at the bottom of the front end and the bottom of the rear end of the main frame 101, respectively, to provide stable support.

[0039] In the above embodiments, please refer to Figure 4-11 The tire packing device 4 includes a compression chamber 401, which has a U-shaped cross-section to accommodate and compress tires. A left support column 402a and a right support column 402b are symmetrically installed on both sides of the compression chamber 401 to provide structural support. A front door mechanism 403 is installed between the left and right support columns 402a and 402b, located on the U-shaped opening side of the compression chamber 401, for opening and closing the front.

A crossbeam 405 is installed between the upper ends of the left and right support columns 402a and 402b, and a pair of compression mechanisms 406 are symmetrically installed on the crossbeam 405 to apply pressure to the tires for compression. The height of the front door mechanism 403 is less than or equal to half the height of the compression chamber 401, creating a gap above the front door mechanism 403 for easy placement of waste tires.

[0040] The front door mechanism 403 includes a first cylinder support 403-1 mounted on the right side of the right pillar 402b and a pair of first transverse connecting beams 403-2 symmetrically mounted on the front side. A first door-pushing cylinder 403-3 is installed inside the first cylinder support 403-1 for driving the front door opening and closing. A pair of first connecting rods 403-4 are symmetrically mounted on the piston rod end of the first door-pushing cylinder 403-3. A pair of first clamping plates 403-5 are movably hinged between the two first connecting rods 403-4 to transmit power. A first door beam 403-6 is installed between two first transverse connecting beams 403-2. Multiple first front door connecting plates 403-7 are installed on the first door beam 403-6. A second front door connecting plate 403-8 is installed at the other end of each first front door connecting plate 403-7. A first round rod 403-9 is hinged through the joint between each first front door connecting plate 403-7 and the second front door connecting plate 403-8, forming a hinged connection that allows the door panel to rotate. A front door panel 403-10 is installed on the inner side of each first front door connecting plate 403-7. The right end of the second first front door connecting plate 403-7 from the top is installed between two first clamping plates 403-5, and the door panel opens and closes via a hydraulic cylinder. Multiple anti-rebound mechanisms 407 are installed in the front door panel 403-10 to prevent the tires from rebounding during compression.

[0041] The rear door mechanism 404 includes a second cylinder support 404-1 mounted on the right side of the right pillar 402b and a pair of second transverse connecting beams 404-2 symmetrically mounted on the rear side. A second door-pushing cylinder 404-3 is installed inside the second cylinder support 404-1 for driving the rear door opening and closing. A pair of second connecting rods 404-4 are symmetrically mounted on the piston rod end of the second door-pushing cylinder 404-3. A pair of second clamping plates 404-5 are movably hinged between the second connecting rods 404-4 to transmit power. A second door beam 404-6 is installed between two second transverse connecting beams 404-2. Multiple first rear door connecting plates 404-7 are installed on the second door beam 404-6. A second rear door connecting plate 404-8 is installed at the other end of each first rear door connecting plate 404-7. A second round rod 404-9 is hinged through the joint between each first rear door connecting plate 404-7 and the second rear door connecting plate 404-8, forming a hinged connection. The inner side of each first rear door connecting plate 404-7 is installed on the U-shaped back of the compression chamber 401. The right end of the second first rear door connecting plate 404-7 from the top is installed between two second clamping plates 404-5. The rear door opens and closes via a hydraulic cylinder. Multiple anti-rebound mechanisms 407 are installed in openings on the U-shaped back of the compression chamber 401 to prevent the tires from rebounding during compression.

[0042] The anti-rebound mechanism 407 includes a mounting base 407-1 installed on the front door panel 403-10 or the U-shaped back of the compression chamber 401. A rotating shaft 407-2 is installed inside the mounting base 407-1. An anti-rebound plate 407-3 is fitted onto the rotating shaft 407-2. The anti-rebound plate 407-3 extends into the compression chamber 401 through a corresponding opening on the front door panel 403-10 or the U-shaped back of the compression chamber 401 to prevent tire rebound. A first connecting ring 407-4 is installed on the anti-rebound plate 407-3. A spring 407-5 is fitted onto the first connecting ring 407-4. The other end of the spring 407-5 is fitted into a second connecting ring 407-6. The second connecting ring 407-6 is installed on the first front door connecting plate 403-7 or the first rear door connecting plate 404-7. The tension of the spring maintains a certain pressure on the anti-rebound plate, preventing the tire from rebounding and expanding after compression. A protective mesh plate 408 is installed between the first front door connecting plate 403-7 or between the first rear door connecting plate 404-7 in the area where the anti-rebound mechanism 407 is located.

[0043] The compression mechanism 406 includes a base plate 406-1 mounted on a crossbeam 405. The base plate 406-1 can also be mounted on the lower side of the crossbeam 405. A compression cylinder 406-2 is installed at the center of the base plate 406-1 to provide compression power. A pair of connecting rods 406-3 are symmetrically installed on the base plate 406-1 on both sides of the compression cylinder 406-2 to guide the direction of movement. A compression connecting seat 406-4 is installed at the end of the piston rod of the compression cylinder 406-2. A compression plate 406-5 is installed on the lower side of the compression connecting seat 406-4, and the lower ends of the pair of connecting rods 406-3 are installed on the compression plate 406-5. The compression connecting seats 406-4 of the two compression mechanisms 406 are connected together by a connecting side plate 406-6. When the compression cylinder actuates, the piston rod extends, pushing the compression connecting seat and the compression plate downwards to compress the tire. The connecting rods ensure smooth movement.

[0044] In the above embodiments, please refer to Figure 12-13The lifting cylinder 5 is a double-acting hydraulic cylinder. Its cylinder body bottom is mounted on the bottom longitudinal beam of the mobile frame 1 through a fixed hinge seat 501. The top of its piston rod is connected to the middle position of the tilting mechanism 6 through a movable hinge pin 502. That is, the top of its piston rod is connected to the first cylinder support 403-1 on the right side of the right support column 402b through a movable hinge pin 502. The top of the piston rod of the lifting cylinder 5 and the first push-door cylinder 403-3 are installed side by side in the first cylinder support 403-1. The lifting cylinder 5 is used to drive the tilting mechanism 6 to rotate the tire packing device 4 around the hinge point between the tilting mechanism 6 and the mobile frame 1. The flipping mechanism 6 includes a first flipping support 601 installed on the side of the rear of the mobile frame 1 and a second flipping support 602 installed on the right side of the tire packing device 4. Both the first flipping support 601 and the second flipping support 602 are composed of a base plate and multiple ear plates installed on the base plate. The two are installed by plugging in, so that the openings on their respective ear plates are aligned and the hinge shafts 603 are inserted to form a hinge connection. The tire packing device 4 performs a flipping movement under the action of the lifting cylinder.

[0045] The working principle of the above embodiments is as follows:

[0046] When in use, the operator first connects the mobile tire hydraulic baler to the transport vehicle via a hook. The transport vehicle tows the mobile tire hydraulic baler to the designated area for the tires to be processed. The equipment is fixed in place by the outriggers 102 at the bottom of the mobile frame 1 to ensure stability. After the hydraulic system is started, pressurized oil is introduced into the lifting cylinder 5, and the piston rod of the double-acting cylinder slowly extends. Since the top of the piston rod is connected to the first cylinder support 403-1 of the right support column 402b of the tire packing device 4 through the movable hinge pin 502, and the first cylinder support 403-1 and the right support column 402b are rigidly fixed, the extension of the piston rod will drive the right support column 402b and the entire tire packing device 4 to rotate around the hinge axis 603 of the flipping mechanism 6. At the same time, the first flipping support 601 installed on the side of the rear of the mobile frame 1 serves as a fixed hinge point, and the second flipping support 602 installed on the right side of the tire packing device 4 moves in a circle around the hinge axis 603 along with the device, so that the tire packing device 4 gradually flips upward from the initial horizontal state parallel to the rear of the mobile frame 1 until the tire packing device 4 lands smoothly on the ground.

[0047] Once the tire baling device 4 reaches the working position, the operator places the tire to be baled into the compression chamber 401 through a gap created above the front door mechanism 403. Simultaneously, a pair of compression mechanisms 406 are activated. Pressurized oil is introduced into the compression cylinder 406-2, and the piston rod of the compression cylinder 406-2 slowly extends along the guide hole of the base plate 406-1, pushing the compression connecting seat 406-4 and the compression plate 406-5 below it to move vertically downwards along the direction defined by the double connecting rod 406-3. This applies uniform pressure to the waste tires accumulated in the compression chamber 401. The double connecting rod guide reduces the deviation of the piston rod of the compression cylinder 406-2 in its downward movement, making the compression process more stable. Under the action of the compression force, the tire gradually undergoes plastic deformation and downward compression, rapidly reducing its volume. The tire expands outwards from its edges towards the compression chamber 401. At this time, the anti-rebound mechanism 407 on the front door panel 403-10 and the U-shaped back of the compression chamber 401 works simultaneously. Under the pressure of the tire expansion force, the anti-rebound plate 407-3 rotates slightly towards the inside of the compression chamber 401 around the rotating shaft 407-2. At the same time, the spring 407-5 is stretched to generate reverse tension, so that the anti-rebound plate 407-3 always maintains close contact with the tire surface, effectively preventing the tire from rebounding and expanding due to elastic recovery during compression. When the compression plate 406-5 descends to the preset stroke, that is, when the tire compression density reaches the set value, the hydraulic system triggers the pressure relay, the compression cylinder 406-2 stops supplying oil and maintains pressure, so that the tire can stably maintain the compressed block structure under continuous pressure.

[0048] After the tire is compressed and packaged, the front door mechanism 403 is activated and opened. Specifically, the first door-pushing cylinder 403-3 is activated by the hydraulic control valve, and its piston rod extends. Through the first connecting rod 403-4, the first clamping plate 403-5 pushes the first door beam 403-6, the first front door connecting plate 403-7, the second front door connecting plate 403-8, and the front door panel 403-10 forward. Then, the first clamping plate 403-5 rotates around the hinged first connecting rod 403-4 to open the door. The compressed tire block is then forked out by a forklift and transferred to the pre-prepared collection area.

[0049] After the tire block is pushed out, the piston rod of the compression cylinder 406-2 slowly retracts under the control of the hydraulic system, driving the compression plate 406-5 back up along the original path to the initial position below the crossbeam 405; at the same time, the piston rod of the first door-pushing cylinder 403-3 retracts, working in the reverse manner of the door opening as described above, so that the front door mechanism 403 returns to the initial closed state, preparing for the next compression operation.

[0050] During the above process, the rear door mechanism 404 does not need to be opened or closed. It only needs to be opened when maintenance is required. The opening method of the rear door mechanism 404 is the same as that of the front door mechanism 403.

[0051] After all the tires to be processed have been packed, the operator shuts off the hydraulic system and generator 2, and initiates the retraction action of the lifting cylinder 5. This involves the piston rod of the double-acting cylinder gradually retracting, pulling the right support column 402b of the tire packing device 4 via the movable hinge pin 502. This causes the entire tire packing device 4 to rotate in the opposite direction around the hinge axis 603 of the flipping mechanism 6, gradually lifting it from the ground and placing it upside down onto the main frame 101 of the mobile chassis 1, returning it to its transport state. Subsequently, the three support legs 102 at the bottom of the mobile chassis 1 are retracted via hydraulic control, allowing the eight tires 103 to re-contact the ground.
