Description

Technical Field

[0001] This utility model relates to the field of turning and turning machines, specifically to a single-beam lifting turning and turning machine. Background Technology

[0002] Currently, most compost turning machines employ a double-beam design to enhance their forward and backward movement and load-bearing capacity. The space between the two beams is used to achieve the lifting function of the turning disc mechanism. Double-beam compost turning machines typically use load-bearing pulleys from a shifting mechanism to drive rotation, enabling left and right movement along the tracks of the two beams. However, when the material thickness and moisture content in the fermentation tank are uneven, the resistance to left and right movement increases, easily causing the left and right moving pulleys to slip and spin freely on the tracks. This leads to the equipment malfunctioning and significantly reduces production efficiency. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and to propose a single-beam lifting and turning machine to solve the problem that the left and right moving pulleys in the existing technology are prone to slipping and spinning on the track.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] A single-beam lifting and turning machine includes two sets of movable columns mounted on a base; it also includes:

[0006] The single-beam frame is fixed at both ends to two sets of movable columns;

[0007] The displacement mechanism, mounted on a single-beam frame, includes a mounting plate, a drive sprocket, a driven sprocket, a chain support pulley, a mounting plate support pulley, and a displacement chain. Two sets of mounting plates are provided, located on opposite sides of the single-beam frame. The drive sprocket, driven sprocket, and chain support pulley are respectively mounted on three sprocket mounting rods, with both ends of each rod fixed to two mounting plates. One end of the displacement chain is fixedly connected to one of the movable columns, and the other end passes sequentially around the chain support pulley and the drive sprocket. The passive sprocket is fixedly connected to another movable column. One end of the sprocket mounting rod for installing the drive sprocket is connected to the output end of the shifting motor. When the shifting motor is started, the drive sprocket rotates. In conjunction with the shifting chain, the shifting mechanism can reciprocate on the single beam frame. The mounting plate supports at least four pulleys, which are installed on the mounting plate and can clamp the single beam frame and slide along it. This structure allows the shifting mechanism to be installed on the single beam frame and also facilitates reciprocating movement on the single beam frame.

[0008] The lifting mechanism is provided in two sets, which are used to lift two sets of movable columns respectively. Each lifting mechanism includes a traveling end beam, a folding stabilizer arm and a lifting drive device. The bottom of the traveling end beam is hinged to the base, the top is hinged to one end of the folding stabilizer arm, the other end of the folding stabilizer arm is hinged to the movable column, the bottom of the movable column is hinged to the base, and a lifting drive device is provided between the traveling end beam and the folding stabilizer arm. By extending and retracting the lifting drive device, the movable column is driven to rotate around the hinge point with the base, thereby realizing the lifting and lowering of the single beam frame.

[0009] The tumbling wheel assembly, installed below the shifting mechanism, has a tumbling function.

[0010] The above technical solution utilizes a single-beam frame to withstand pressure and operational intensity. The shifting mechanism employs mounting plate support pulleys that move left and right on the single-beam track. A single chain (shifting chain) via a drive sprocket, a driven sprocket, and a chain support pulley on the shifting mechanism enables forced left and right movement, preventing slippage and idle rotation of the mounting plate support pulleys on the track, thus improving work efficiency. Furthermore, when the single-beam frame tilts downwards at the movable column, it simultaneously changes the vertical downward angle of the tilting wheel assembly, gradually lifting the tilting wheel assembly off the ground and achieving the purpose of raising the tilting wheel assembly.

[0011] Furthermore, a reinforcing plate is provided between the two sets of mounting plates, on the one hand to enhance the stability between the two sets of mounting plates, and on the other hand to install the turning wheel assembly.

[0012] Furthermore, the shifting motor is mounted on a mounting plate.

[0013] Furthermore, several pulley mounting rods are installed between the two sets of mounting plates, distributed on the upper and lower sides of the single beam frame. Each pulley mounting rod is equipped with two mounting plate support pulleys, and the two mounting plate support pulleys are located on the front and rear sides of the single beam frame, with the mounting plate support pulleys in contact with the single beam frame.

[0014] Furthermore, a synchronous detection switch is installed on the traveling end beam of both sets of lifting mechanisms to ensure that the lifting and lowering actions of the lifting drive devices on both sides operate synchronously and to prevent deformation of the single beam frame.

[0015] Furthermore, the lifting drive device is one of a lifting hydraulic cylinder, a lifting air cylinder, or an electric telescopic rod.

[0016] Furthermore, a walking mechanism is provided below the base, which can be a tracked walking mechanism or a wheeled walking mechanism.

[0017] Furthermore, the turning wheel assembly includes a slewing bearing, a wheel mounting base, a cutter wheel, and a slewing motor. The slewing bearing is fixed to the shifting mechanism via a connecting column. The wheel mounting base is fixed to the bottom of the slewing bearing. Two sets of cutter wheels are provided, respectively fixed to both ends of the rotating shaft. The rotating shaft is mounted on the wheel mounting base via a support column and driven by a wheel drive assembly fixed to the wheel mounting base. The slewing motor is mounted on the mounting plate of the shifting mechanism via a motor mounting base. The output end of the slewing motor is provided with a slewing drive wheel, which is located on one side of the slewing bearing and meshes with the outer circumference of the slewing bearing. Starting the slewing motor can drive the slewing drive wheel to rotate, thereby rotating the slewing bearing to change the direction of the cutter wheel and achieve 360° rotation of the cutter wheel in the horizontal direction.

[0018] Furthermore, the single-beam lifting and turning machine also includes a movable baffle assembly to prevent the material from scattering after turning. The movable baffle assembly includes a baffle, a sprocket drive shaft, a baffle drive sprocket, a baffle drive chain, and a baffle drive motor. Two sets of baffles are arranged in parallel, with their ends connected by a baffle connecting rod, forming a receiving space in the middle. The wheel disc mounting base is located within this receiving space, and the two baffles are respectively positioned above the two cutter wheel discs. Two sprocket drive shafts are provided, located on the front and rear sides of the wheel disc mounting base. Both ends of the sprocket drive shaft are mounted on the two baffles, and each end is equipped with a baffle drive sprocket. The two baffle drive sprockets on the same baffle are connected by a baffle drive chain. A chain bracket is fixed to the baffle drive chain, and the chain bracket is welded to the wheel disc mounting base. One end of one sprocket drive shaft is connected to the output end of the baffle drive motor. Driven by a baffle drive motor, the baffle can move back and forth relative to the wheel mounting base, flexibly adjusting the position of the baffle and preventing material spillage.

[0019] Furthermore, the turning wheel assembly is provided with a housing, the side of the baffle is provided with a roller, the housing is provided with a slide rail that matches the roller, and the roller is placed in the slide rail.

[0020] Technical effects of this utility model:

[0021] Compared with the prior art, the single-beam lifting and turning machine of this utility model adopts a single chain drive and forced execution to avoid slippage and improve work efficiency. The entire single-beam frame can be pushed backward by the walking end beam, folding stabilizing arm and lifting drive device, thereby changing the vertical downward angle of the turning wheel assembly, so that the turning wheel assembly gradually lifts off the ground and achieves the purpose of raising the blade wheel. The structure is simple and the operation is convenient and quick. Attached Figure Description

[0035] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0036] Example 1

[0037] like Figure 1 As shown, this embodiment relates to a single-beam lifting and turning machine, which includes a movable column 1, a base 2, a single-beam frame 3, a shifting mechanism 4, a lifting mechanism 5, a turning wheel assembly 6, a walking mechanism 7, and a moving baffle assembly 8.

[0038] like Figure 1 As shown, the movable column 1 is provided in two sets, and the bottom of the two sets of movable columns 1 are respectively installed on their respective bases 2.

[0039] like Figure 1 As shown, the two ends of the single beam frame 3 are respectively fixed to the top of the two sets of movable columns 1.

[0040] like Figure 2 and Figure 3As shown, the displacement mechanism 4 is mounted on the single-beam frame 3 and includes a mounting plate 401, a drive sprocket 402, a driven sprocket 403, a chain support pulley 404, a mounting plate support pulley 405, and a displacement chain 406. Two sets of mounting plates 401 are provided, located on the front and rear sides of the single-beam frame 3 respectively. The drive sprocket 402, driven sprocket 403, and chain support pulley 404 are respectively mounted on three sprocket mounting rods 407. The drive sprocket 402 is located diagonally above the driven sprocket 403, and the chain support pulley 404 is located on one side of the drive sprocket 402. Both ends of the sprocket mounting rods 407 are fixed to two mounting plates 401, and all three sprocket mounting rods 407 are located above the single-beam frame 3. One end of the shifting chain 406 is fixedly connected to one of the movable columns 1, and the other end passes through the chain support pulley 404, the drive sprocket 402 and the passive sprocket 403 in sequence before being fixedly connected to another movable column 1. One end of the sprocket mounting rod 407 that mounts the drive sprocket 402 is connected to the shifting motor 408 fixed on the mounting plate 401. When the shifting motor 408 is started, the drive sprocket 402 is driven to rotate, which cooperates with the shifting chain 406, so that the shifting mechanism 4 can move back and forth on the single beam frame 3. This structure avoids the phenomenon of the mounting plate support pulley 405 slipping and spinning on the track. Two sets of pulley mounting rods 409 are provided, located on the upper and lower sides of the single-beam frame 3 respectively. Each set of pulley mounting rods 409 is equipped with two mounting plate support pulleys 405, and the two mounting plate support pulleys 405 are located on the front and rear sides of the single-beam frame 3 respectively. The mounting plate support pulleys 405 are in close contact with the single-beam frame 3, which serves two purposes: firstly, to install the shifting mechanism 4 on the single-beam frame 3, and secondly, to facilitate reciprocating movement on the single-beam frame 3. A reinforcing plate 410 is also provided between the two sets of mounting plates 401, which serves two purposes: firstly, to enhance the stability between the two sets of mounting plates 401, and secondly, to install the turning wheel assembly 6.

[0041] like Figure 4 and Figure 5As shown, the lifting mechanism 5 is provided in two sets, respectively used for lifting two sets of movable columns 1. Each set of lifting mechanism 5 includes a traveling end beam 501, a folding stabilizing arm 502, and a lifting drive device 503; the bottom of the traveling end beam 501 is hinged to the base 2, the top is hinged to one end of the folding stabilizing arm 502, the other end of the folding stabilizing arm 502 is hinged to the movable column 1, the bottom of the movable column 1 is hinged to the base 2, and the lifting drive device 503 is provided between the traveling end beam 501 and the folding stabilizing arm 502. Preferably, the lifting drive device 503 is a lifting cylinder, the cylinder body of the lifting cylinder is hinged to the traveling end beam 501, and the piston rod is hinged to the folding stabilizing arm 502. By extending and retracting the piston rod of the lifting cylinder, the movable column 1 is driven to tilt backward, thereby realizing the lifting of the single beam frame 3. To prevent deformation of the single beam frame 3, a synchronous detection switch 504 is provided on the traveling end beam 501 of both sets of lifting mechanisms 5, so that the lifting actions of the lifting cylinders on both sides can operate synchronously.

[0042] like Figure 1 As shown, the tilting wheel assembly 6 is installed below the shifting mechanism 4 and has a tilting function. Its angle changes with the lifting and lowering of the single-beam frame 3, thereby achieving the purpose of lifting and lowering the tilting wheel assembly 6. Specifically, as... Figure 2 , Figure 3 and Figure 6 As shown, the tumbling wheel assembly 6 includes a slewing bearing 601, a wheel mounting base 602, a cutter wheel 603, and a rotary motor 604. The slewing bearing 601 is fixed to the reinforcing plate 410 of the shifting mechanism 4 via a connecting column 605. The wheel mounting base 602 is fixed to the bottom of the slewing bearing 601. Two sets of cutter wheel 603 are provided, respectively fixed to both ends of the rotating shaft 606. The rotating shaft 606 is mounted on the wheel mounting base 602 via a support column 607 and is driven by a wheel drive assembly fixed to the wheel mounting base 602. A housing 6 is provided on the outer periphery of the wheel drive assembly. 13. The housing 613 is fixed on the wheel mounting base 602, which has a protective function for the wheel drive assembly; the rotary motor 604 is mounted on the mounting plate 401 of the shifting mechanism 4 through the motor mounting base 608. The output end of the rotary motor 604 is provided with a rotary drive wheel 609. The rotary drive wheel 609 is located on one side of the rotary bearing 601 and meshes with the outer circumference of the rotary bearing 601. Starting the rotary motor 604 can drive the rotary drive wheel 609 to rotate, thereby causing the rotary bearing 601 to rotate, so as to change the direction of the cutter wheel 603 and realize the 360° rotation of the cutter wheel 603 in the horizontal direction.

[0043] As one feasible implementation method, such as Figure 2As shown, the wheel drive assembly includes a wheel drive motor 610 fixed to the bottom of the wheel mount 602, a drive wheel 611 fixed to the output end of the wheel drive motor 610, and a driven wheel 612 meshing with the drive wheel 611. The driven wheel 612 is fixed to the rotating shaft 606. The wheel drive motor 610 drives the drive wheel 611 to rotate, which in turn drives the driven wheel 612 to rotate, thereby realizing the rotation of the rotating shaft 606 and achieving the tumbling and throwing operation. This utility model is not limited to this structural form; other drive assemblies capable of driving the cutter wheel 603 to perform tumbling and throwing operations are also acceptable.

[0044] like Figure 1 As shown, the walking mechanism 7 is located at the bottom of the base 2 and can be either tracked or wheeled.

[0045] like Figure 6 , Figure 7 and Figure 8As shown, the movable baffle assembly 8 includes a baffle 801, a sprocket drive shaft 802, a baffle drive sprocket 803, a baffle drive chain 804, and a baffle drive motor 805. Two sets of baffles 801 are provided, arranged in parallel, with their ends connected by a baffle connecting rod 806, forming a receiving space in the middle. The wheel mounting base 602 is located within this receiving space. The two baffles 801 are respectively located above the two cutter wheel discs 603. The baffles 801 can adopt a U-shaped or V-shaped structure, but are not limited to these structures; other baffle structures that can prevent spillage are also acceptable. Two sprocket drive shafts 802 are provided, located on the front and rear sides of the wheel mounting base 602 respectively. Each end of the sprocket drive shaft 802 is mounted on a baffle 801, and a baffle drive sprocket 803 is mounted on each end. The two baffle drive sprockets 803 on the same baffle 801 are connected by a baffle drive chain 804. A chain bracket 807 is fixed to the baffle drive chain 804 and welded to the wheel mounting base 602. Rollers 808 are provided on the side of the baffle 801. A slide rail 809 matching the roller 808 is provided on the housing 613. The roller 808 is placed in the slide rail 809, which not only facilitates the forward and backward movement of the baffle 801 but also provides further support for the moving baffle assembly 8, making the moving baffle assembly 8 more stable. One end of the sprocket drive shaft 802 is connected to the output end of the baffle drive motor 805. During operation, the baffle drive motor 805 drives the sprocket drive shaft 802 connected to it to rotate, thereby driving the two baffle drive sprockets 803 on the sprocket drive shaft 802 to rotate synchronously, so that the baffle drive chains 804 on each set of baffles 801 rotate synchronously. Since the baffle drive chains 804 are fixed to the wheel mounting base 602 through the chain bracket 807, the rotation of the baffle drive chains 804 can drive the baffles 801 to move back and forth relative to the housing 613, so that the position of the baffles 801 can be adjusted as needed to better prevent material spillage.

[0046] This invention employs a single-beam structure, eliminating the need for a cumbersome lifting system and double the left-right shifting pulley mechanism on the main beam. This allows the single beam to easily bear the pressure and operational intensity. Since the turning wheel assembly 6 is directly below the single-beam frame 3, it prevents materials from being thrown onto the equipment. Furthermore, the cleverly designed, back-and-forth movable anti-spillage baffle 801 ensures controllable material spillage. This invention also utilizes a mounting plate to support the pulley 405, which slides left and right on the single-beam frame 3. Forced operation is achieved via a single chain through the drive sprocket 402, driven sprocket 403, and chain support pulley 404 on the shifting mechanism 4. This structure prevents slippage, allowing continuous material turning and improving work efficiency. This invention also uses a rotary bearing 601 to enable the 360° horizontal rotation of the blade wheel 603, allowing it to fully turn and shovel materials, making it more flexible and accelerating fermentation and evaporation. The movable columns 1 on both sides of this invention are tilted and flipped via a lifting mechanism 5. When the lifting cylinder extends outward, it pushes the folding stabilizing arm 502, which in turn pushes the movable column 1 and causes the single-beam frame 3 to tilt backward. At this time, the traveling end beam 501 acts as a fulcrum, and the folding stabilizing arm 502 ensures that the single-beam frame 3 will not deform or misalign during the lifting process. When the single-beam frame 3 tilts backward, it simultaneously causes the tilting wheel assembly 6 to change its vertical downward angle, gradually lifting it off the ground and achieving the purpose of raising the cutter wheel 603. Conversely, when the lifting cylinder retracts inward, it can cause the tilting wheel assembly 6 to tilt vertically downward, thereby resetting the cutter wheel 603. To prevent deformation of the single-beam frame 3 during the lifting process, synchronous detection switches 504 are installed on the traveling end beams 501 of the two sets of lifting mechanisms 5. The synchronous detection switches 504 are connected to the electrical control detection system. The electrical control detection system controls the two lifting cylinders to move according to the signal sent by the synchronous detection switches 504, so that the movable columns 1 on both sides move synchronously, effectively avoiding the problem of deformation of the single-beam frame 3 during the lifting process.
