Description

Technical Field

[0001] This utility model relates to the field of biomass loosening tooling technology, specifically to a biomass loosening equipment. Background Technology

[0002] Biomass refers to all kinds of organisms formed through photosynthesis, including all plants, animals, and microorganisms. Among them, crop straw is a common type of biomass that can be used to produce fertilizer or generate electricity.

[0003] After crops are harvested, the straw is compressed and baled into cylindrical or square shapes using baling equipment. This baling is then secured with straps, forming multiple bales of roughly the same size for easy transport. The straps are typically made by twisting multiple straw stalks in a spiral. Because the straps are made from straw, there is no need to separate them during the subsequent unbundling process, simplifying the unbundling procedure.

[0004] After the bales are transported to their destination, the cylindrical or square straw, which possesses a certain structural strength, needs to be loosened before use. Loosening the bales involves cutting the bales straps and breaking up the straw. Current loosening methods typically use a auger shaft, where the spiral blades on the shaft act as blades, using the shaft's rotation to break up the bales and push the material forward. However, this auger method tends to cut the straw into small, uneven pieces, making it unsuitable for subsequent processes requiring fixed-length cutting. It's important to note that fixed-length straw cutting devices include rollers and blades built into them. Due to limitations in blade size and strength, straw in its bale state cannot be directly used for cutting. Instead, the bales must be cut first, and then the straw broken up to reduce the compressive strength between the straw strands before it can be properly cut by the blades. Fixed-length cutting is also generally required for other biomass.

[0005] Therefore, there is an urgent need for a loosening device that can loosen biomass bales while basically preserving the original length of the biomass. Utility Model Content

[0006] (a) Technical problems to be solved

[0007] In view of the above-mentioned shortcomings and deficiencies of the prior art, the present invention provides a biomass loosening device, which solves the technical problem that the existing biomass loosening device is prone to cutting the biomass during loosening, resulting in large differences in the length of the biomass.

[0015] One end of the first rotating shaft is connected to the first cutting wheel, and the other end is connected to the rotary drive; the driving wheel is sleeved on the first rotating shaft;

[0016] The first transmission gear and the second transmission gear are rotatably connected to the housing, and the two mesh with each other for transmission;

[0017] The first conveyor belt is wound around the driving wheel and the first transmission gear; the second conveyor belt is wound around the second transmission gear and the driven wheel;

[0018] One end of the second rotating shaft is connected to the driven wheel, and the other end is connected to the second cutting wheel.

[0019] Optionally, both the first transmission gear and the second transmission gear are constructed as wheel bodies with an H-shaped radial cross-section;

[0020] The middle part of the wheel is connected to either the first or the second conveyor belt; the two sides of the wheel are respectively provided with toothed wheels.

[0021] Optionally, the biomass loosening equipment further includes an inclined vibration mechanism; the vibration mechanism includes a sliding plate, an elastic fulcrum, and a vibration fulcrum;

[0022] The slide plate is positioned below the discharge port, and the end of the slide plate closer to the discharge port is higher than the end farther from the discharge port.

[0023] The bottom of both ends of the slide plate is provided with the elastic fulcrum and the vibration fulcrum respectively; the vibration fulcrum can drive the slide plate to move back and forth along the thickness direction of the slide plate; the elastic fulcrum can apply an elastic force in the thickness direction of the slide plate.

[0024] Optionally, the vibration fulcrum includes a thruster, a push rod, a sleeve, and a first elastic element;

[0025] One end of the push rod is connected to the pusher, and the other end is slidably connected to the sleeve along the thickness direction of the slide plate; the other end of the sleeve is connected to the slide plate.

[0026] The first elastic element is sleeved on the push rod and the sleeve; one end of the first elastic element is connected to the pusher, and the other end is connected to the slide plate.

[0027] Optionally, the end of the slide plate away from the discharge port is configured as a conical discharge port; and the diameter of the conical discharge port near the discharge port is larger than the diameter of the port away from the discharge port.

[0028] Optionally, the skateboard is provided with multiple deflectors;

[0029] The length direction of the guide plate is perpendicular to the discharge port of the slide plate.

[0030] Optionally, the protrusion is a ball bearing or an arc-shaped plate.

[0031] (III) Beneficial Effects

[0032] The beneficial effects of this utility model are:

[0033] The protruding part has a protruding structure that can abut against the material. On the one hand, it can reduce the falling speed of the material and reduce the impact force of the material on the cutting wheel. On the other hand, it can guide the material and automatically adjust the position of the material relative to the cutting point of the first and second cutting wheels, thereby improving the cutting accuracy.

[0034] The first and second cutting wheels, which are at the same horizontal height, are driven by a drive mechanism to rotate, so that both sides of the strapping can be cut at the same time when cutting the strapping, ensuring that the strapping can be fully separated from the material or easily separated in the subsequent disintegration process.

[0035] Because the distance between the cutting points of the first and second cutting wheels is no greater than the inner diameter of the strapping, the cutting wheels only cut along the contour edge of the material body. The entire cutting process has minimal impact on the overall material, ensuring the integrity of the biomass after cutting and facilitating subsequent fixed-length cutting. Therefore, the first and second cutting wheels are not used to push the material; the material falls under its own weight, effectively preventing excessive force from being applied to the cutting wheels during descent and thus shortening their lifespan.

[0036] By positioning the first and second cutting wheels at the same horizontal level, both sides of the strap can be cut simultaneously, shortening the time difference between the two sides of the strap breaking and ensuring that both sides of the strap can be cut. The first and second cutting wheels are constructed as ratchet wheels, with ratchet teeth (i.e., blades) rotating in opposite directions. This allows the first ratchet to cut from the bottom of the strap, and the second ratchet to cut from the top, achieving bidirectional force on the strap during cutting. This prevents axial movement of the strap during cutting, improving cutting stability and ensuring that both sides can be cut simultaneously. Attached Figure Description

[0053] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0054] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0055] Furthermore, in this utility model, the use of terms such as "first," "second," etc., is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0056] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; "connection" can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0057] See Figure 1 and Figure 2 This utility model provides a biomass loosening device, which includes a housing 1, protrusions 2, a first cutting wheel 3, a second cutting wheel 4, and a drive mechanism 5. The top of the housing 1 is provided with a cylindrical or square vertical feeding port 11. Multiple protrusions 2 are embedded in the inner wall of the vertical feeding port 11. The bottom of the housing 1 is provided with a discharge port 12. The first cutting wheel 3 and the second cutting wheel 4 are both built into the housing 1 and are located below the vertical feeding port 11. The drive mechanism 5 is external to the housing 1. The drive mechanism 5 can drive the first cutting wheel 3 and the second cutting wheel 4 to rotate in opposite directions. The first cutting wheel 3 is provided with a first ratchet 31. The second cutting wheel 4 is provided with a second ratchet 41. The first cutting wheel 3 and the second cutting wheel 4 are located at the same horizontal height, and the horizontal distance between their cutting points is not greater than the inner diameter of the strapping 6.

[0058] In this embodiment, the housing 1 is vertically arranged, with a vertical feeding port 11 at its top, allowing materials to be fed vertically and fall freely under their own weight. After being cut by the first cutting wheel 3 and the second cutting wheel 4, the strapping 6 is discharged from the discharge port 12. The housing 1 does not require energy-consuming feeding, saving processing costs.

[0059] The spacing between the radially opposite protrusions 2 is adapted to the diameter of the material body (i.e., the material after removing the strapping 6). Optionally, the protrusions 2 are ball bearings or curved plates. The protrusions 2 have a raised structure that can abut against the material. On the one hand, this reduces the falling speed of the material, allowing it to fall more slowly within the housing 1, reducing the impact force of the material on the cutting wheels. On the other hand, it guides the material, automatically adjusting its position relative to the cutting points of the first cutting wheel 3 and the second cutting wheel 4, thus improving cutting accuracy. Optionally, a pusher (not shown) is also provided above the vertical feeding port 11. The pusher has a vertically retractable push plate, the outer diameter of which is smaller than the spacing between the radially opposite protrusions 2, so that the push plate can push the material vertically, causing the material to fall at a preset speed.

[0060] The drive mechanism 5 drives the first cutting wheel 3 and the second cutting wheel 4, which are at the same horizontal height, to rotate. This allows for simultaneous cutting of both sides of the strapping, ensuring that the strapping 6 can be fully separated from the material or easily separated in the subsequent dispersing process. It should be noted that the length of the strapping 6 after cutting both sides is generally longer than the set cutting length of the fixed-length cutting device. No additional processing is required for the strapping 6; it can be directly cut to the required length along with the material body.

[0061] Since the distance between the cutting points of the first cutting wheel 3 and the second cutting wheel 4 is no greater than the inner diameter of the strapping 6, and the cutting point refers to the free end of the ratchet, that is, the outermost extension of the ratchet cutting surface during rotation, preferably slightly smaller than the inner diameter of the strapping 6, the cutting wheels only cut at the contour edge of the material body. The entire cutting process has little impact on the overall material body, ensuring the integrity of the biomass after the cutting wheel completes the cutting, which facilitates subsequent fixed-length cutting of the material. Based on this, the first cutting wheel 3 and the second cutting wheel 4 are not used to push the material. The material falls by its own gravity, which can effectively avoid applying excessive force to the cutting wheel during the falling process, thus shortening the service life of the cutting wheel.

[0062] To ensure the binding strength of the strap 6 to the material, the strap 6 will partially embed itself into the material after binding. Therefore, if only one side of the strap 6 is cut, the uncut side of the strap 6 may still have a certain binding force on the material, which is not conducive to the subsequent dispersion of the material. Based on this, the present invention sets the first cutting wheel 3 and the second cutting wheel 4 at the same horizontal height, so that both sides of the strap 6 can be cut simultaneously, shortening the time difference between the breakage of the two sides of the strap 6, and ensuring that both sides of the strap 6 can be cut. The first cutting wheel 3 and the second cutting wheel 4 are constructed as ratchet wheels, and the ratchet teeth are also blades. The ratchet teeth on the two wheels rotate in opposite directions, so that the first ratchet tooth 31 can start cutting from the bottom of the strap 6, and the second ratchet tooth 41 can start cutting from the top of the strap 6. This achieves bidirectional force on the strap 6 during the cutting process, making it less likely for the strap 6 to move axially during cutting, improving cutting stability, and ensuring that both sides can be cut simultaneously.

[0063] like Figure 3 and Figure 4 As shown, the drive mechanism 5 includes a first rotating shaft 51, a second rotating shaft 52, and a drive wheel 53, a first transmission gear 54, a second transmission gear 55, a driven wheel 56, a first conveyor belt 57, a second conveyor belt 58, and a rotary driver 59, all externally mounted on the housing 1. One end of the first rotating shaft 51 is connected to the first cutting wheel 3, and the other end is connected to the rotary driver 59, which can be a motor or an electric motor. The drive wheel 53 is mounted on the first rotating shaft 51. The first transmission gear 54 and the second transmission gear 55 are rotatably connected to the housing 1, and they mesh for transmission. The first conveyor belt 57 is wound around the drive wheel 53 and the first transmission gear 54. The second conveyor belt 58 is wound around the second transmission gear 55 and the driven wheel 56. One end of the second rotating shaft 52 is connected to the driven wheel 56, and the other end is connected to the second cutting wheel 4. The conveyor belt can be a belt or a chain.

[0064] Optionally, multiple vertical feeding ports 11 are provided on the housing 1, which can simultaneously feed multiple bales, resulting in higher bale unloading efficiency. The preferred installation positions of the drive mechanism 5 are on multiple side plates of the housing 1. Due to the significant wear of gear transmission, its service life is relatively short; furthermore, the large outer diameter of the material necessitates a large number of gears on the first rotating shaft 51 and the second rotating shaft 52. This invention achieves direction reversal by meshing the first transmission gear 54 and the second transmission gear 55, combined with conveyor belt transmission, ultimately causing the first cutting wheel 3 and the second cutting wheel 4 to rotate in opposite directions. Using a conveyor belt and fewer gears for transmission extends the service life of the drive mechanism 5 and meets the spacing requirements between transmission components.

[0065] See Figure 5 Both the first transmission gear 54 and the second transmission gear 55 are constructed as wheels with an H-shaped radial cross-section; the middle part 541 of the wheel body is connected to either the first conveyor belt 57 or the second conveyor belt 58; and gear teeth 542 are correspondingly provided on both sides of the wheel body. Specifically, grooves are formed on the transmission gears, and the conveyor belt is wound around the grooves to achieve conveyor belt transmission. Gear teeth are provided on both sides of the grooves, i.e., on the circumference of the transmission gears, to achieve gear transmission. In this way, the first transmission gear 54 and the second transmission gear 55 can both perform gear transmission to complete reversal and achieve synchronous drive of the first cutting wheel 3 and the second cutting wheel 4 through conveyor belt transmission.

[0066] See you again Figure 1The biomass loosening equipment also includes an inclined vibration mechanism 7; the vibration mechanism 7 includes a sliding plate 71, an elastic fulcrum 72, and a vibration fulcrum 73; the sliding plate 71 is located below the discharge port 12, and the end of the sliding plate 71 closer to the discharge port 12 is higher than the end farther from the discharge port 12; the elastic fulcrum 72 and the vibration fulcrum 73 are correspondingly arranged at the bottom of both ends of the sliding plate 71; the vibration fulcrum 73 can drive the sliding plate 71 to reciprocate along the thickness direction of the sliding plate 71; the elastic fulcrum 72 can apply an elastic force in the thickness direction of the sliding plate 71. Specifically, because the material itself is compressed and shaped, after the strapping 6 is cut, the material body still has a certain structural strength and needs to be broken up. By tilting the sliding plate 71, the material body can slide down the top surface of the sliding plate 71 after falling onto it. By arranging elastic fulcrums 72 and vibration fulcrums 73 at both ends of the slide plate 71, the specific number of fulcrums is set according to actual needs. The vibration fulcrums 73 apply a force in the thickness direction to the slide plate 71, causing the slide plate 71 to reciprocate. The elastic fulcrums 72 cooperate with the slide plate 71 in reciprocating motion to achieve the purpose of vibration. This not only improves the smoothness of the material body sliding downward, but also disperses the material body, providing more dispersed material for the subsequent fixed-length cutting device, thus improving the processing convenience of the fixed-length cutting device. Optionally, the vibration fulcrums 73 are hinged to the bottom of the slide plate 71 (not shown in the figure), allowing the slide plate 71 to rotate around the hinge point, further improving the vibration effect.

[0067] See Figure 6 The vibration fulcrum 73 includes a thruster 731, a push rod 732, a sleeve 733, and a first elastic element 734. One end of the push rod 732 is connected to the thruster 731, and the other end is slidably connected to the sleeve 733 along the thickness direction of the slide plate 71. The other end of the sleeve 733 is connected to the slide plate 71. The first elastic element 734 is sleeved on the push rod 732 and the sleeve 733. One end of the first elastic element 734 is connected to the thruster 731, and the other end is connected to the slide plate 71. Specifically, the thruster 731 can be a cylinder or an electric push rod, and the first elastic element 734 and the elastic fulcrum 72 can be springs. In one embodiment, the pusher 731 is driven to operate at a set time. When the pusher 731 drives the push rod 732 to collide with the bottom of the slide plate 71, it applies a force. Based on this force, the slide plate 71 begins to vibrate. The first elastic element 734 and the elastic fulcrum 72 cooperate to apply an elastic force, achieving vibration for a longer period of time. After a set time, the vibration weakens, and the pusher 731 drives the push rod 732 to collide with the bottom of the slide plate 71 again, repeating the above operation. Through this design, the pusher 731 only needs to be pulsed, eliminating the need for continuous driving and saving manufacturing costs.

[0068] In one embodiment, see Figure 7The end of the slide plate 71 furthest from the discharge port 12 is constructed as a conical discharge port 711; and the diameter of the conical discharge port 711 near the discharge port 12 is larger than the diameter of the end far from the discharge port 12. The conical discharge port 711 guides the dispersed material, and the material processed from the conical discharge port 711 is essentially vertical, facilitating subsequent fixed-length cutting. Optionally, a baffle is also provided on the slide plate 71 to block the material and prevent it from falling out of the slide plate 71.

[0069] In another embodiment, see Figure 8 The slide plate 71 is equipped with multiple guide plates 74; the length direction of the guide plates 74 is perpendicular to the discharge port of the slide plate 71. When the material body slides along the top surface of the slide plate 71, it collides with the guide plates 74, and the guide plates 74 can guide the flow, so that the material body is discharged in a vertical state, which is convenient for subsequent fixed-length cutting.
