Technical Field
[0001] This utility model relates to the field of agricultural machinery technology, specifically to a straw recycling device for agricultural straw recycling and processing, which has an easy-to-clear blockage function. Background Technology
[0002] With the acceleration of agricultural modernization and the popularization of environmental protection concepts, the recycling and reuse of agricultural straw has become an important part of agricultural production. After recycling and processing, straw can be used as feed, raw material for organic fertilizer, biomass fuel, etc., realizing resource recycling and reducing environmental pollution caused by burning. Currently, most straw recycling devices on the market consist of a straw chopping mechanism and a processing bin. The chopping mechanism chops the straw and discharges it through the hopper. However, in actual use, due to the soft texture and varying lengths of the straw, blockages easily occur inside the processing bin or at the connection between the feed hopper, discharge hopper, and processing bin. Existing devices often use bolts or complex snap-fit structures for the processing bin cover. When blockages occur, tools are needed to remove the bolts or unlock the complex snaps to open the cover for clearing, which is cumbersome, time-consuming, and severely impacts straw recycling efficiency. Furthermore, some devices have poor support stability, causing the equipment to shake during the clearing process, further increasing the difficulty of clearing blockages. In addition, the sealing performance between the cover and the processing bin is insufficient, allowing straw fragments to leak out during chopping, resulting in resource waste and requiring additional cleaning of the leaked fragments, further reducing operational efficiency. Therefore, there is an urgent need for a straw recycling device with an easy-to-open cover structure, a stable support, and a good seal that facilitates unblocking, in order to overcome the shortcomings of existing technologies. Utility Model Content
[0003] To address the problems of cumbersome opening of the bin cover, poor support stability, and insufficient sealing performance in existing straw recycling devices, this utility model provides a straw recycling device that facilitates unblocking. By setting up a removable limiting mechanism, the bin cover can be quickly opened and locked. Adjustable support feet improve support stability, and a sealing gasket is added to enhance sealing performance, thereby achieving the purpose of rapid unblocking and improved recycling efficiency.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a straw recycling device that facilitates unblocking, comprising a support, on which a processing chamber is fixedly installed, a feeding hopper is connected to one side of the top of the processing chamber, and a discharging hopper is connected to the side of the bottom of the processing chamber away from the feeding hopper; a chamber cover is rotatably connected to the top of the processing chamber away from the feeding hopper via a hinge, and a handle for easy gripping is welded and fixed to the top of the chamber cover; two sets of easy-to-disassemble limiting mechanisms are symmetrically arranged between the chamber cover and the processing chamber; and a straw chopping mechanism for chopping straw is installed on one side of the support. The easy-to-disassemble limiting mechanism includes a limiting block welded and fixed to the top of the outer wall of the processing chamber, and a limiting component disposed on the limiting block. An arc-shaped groove is formed inside the limiting block. An arc-shaped slider, adapted to slide along the arc-shaped groove, is welded and fixed to the bottom of the outer wall of the chamber cover. A circular limiting hole is formed at the end of the arc-shaped slider away from the chamber cover. The limiting component includes a limiting cavity formed inside the limiting block and perpendicularly connected to the arc-shaped groove. A limiting slide plate is slidably disposed inside the limiting cavity. The limiting slide plate is close to... One end of the arc-shaped slide groove is integrally formed with a conical limiting head that is adapted to be inserted into the limiting hole. The end of the limiting slide away from the limiting head is welded and fixed with a pull rod. The end of the pull rod away from the limiting slide groove passes through the limiting block and extends to the outside. The extended end is welded and fixed with a pull ring. The outer circumference of the pull ring is integrally formed with anti-slip texture. A spring is sleeved on the pull rod inside the limiting slide cavity. One end of the spring abuts against the end face of the limiting slide away from the limiting head, and the other end abuts against the cavity wall of the limiting slide cavity away from the arc-shaped slide groove. The straw chopping mechanism includes a geared motor fixed to one side of a support by bolts. A rotating shaft is rotatably connected to the side of the support near the geared motor via a bearing. One end of the rotating shaft passes through the side wall of the processing chamber and extends into the interior. Three sets of cutters are circumferentially welded and fixed to the extended end, with the cutter blades facing the direction of the feed hopper. A driven wheel is keyed to the end of the rotating shaft away from the cutters. A driving wheel is keyed to the output shaft of the geared motor. The driving wheel and the driven wheel are connected by a V-belt drive. Furthermore, the outer surface of the arc-shaped slider and the inner surface of the arc-shaped groove are both coated with a wear-resistant coating, which is a chrome-plated layer or a ceramic coating with a thickness of .-.mm. This is used to reduce sliding wear between the arc-shaped slider and the arc-shaped groove and extend the service life of the easy-to-disassemble limit mechanism. Furthermore, a sealing gasket is glued to the side of the bin cover facing the processing bin. The sealing gasket is made of rubber or silicone and has a thickness of 2-3mm (preferably 2.5mm). The outline of the sealing gasket is perfectly matched with the outline of the opening of the processing bin to enhance the sealing between the bin cover and the processing bin and prevent straw fragments from leaking out during the chopping process. Furthermore, each of the four corners of the bottom of the support is provided with an adjustable support foot. The adjustable support foot includes an M16×50 specification screw that is vertically welded and fixed to the bottom of the support, and a cylindrical foot pad that is threaded to the screw. The bottom of the foot pad is integrally formed with evenly distributed anti-slip protrusions. The foot pad is made of nitrile rubber. The horizontal height and stability of the support can be adjusted by rotating the foot pad to ensure that the equipment does not shake during the unblocking process.
[0005] Normal working status: Equipment installation: Rotate the adjustable support feet at the bottom of the support to ensure that the bottom of the foot pads fits tightly against the ground, ensuring that the support is level and stable; Straw chopping: Start the geared motor, the output shaft of the geared motor drives the drive wheel to rotate, the drive wheel drives the driven wheel to rotate through the belt, the driven wheel drives the rotating shaft and the cutter to rotate at high speed; put the straw into the processing chamber from the feed hopper, the rotating cutter chops the straw, and the chopped straw is discharged from the discharge hopper under the action of gravity, completing the straw recycling and chopping operation; Cover locking: At this time, the limiting mechanism is locked and the spring is in a naturally extended state, pushing the limiting slide to move towards the arc-shaped slide groove, so that the limiting head is inserted into the limiting hole of the arc-shaped slider, restricting the sliding of the arc-shaped slider in the arc-shaped slide groove, thereby tightly locking the cover to the top of the processing chamber, and the sealing gasket fits against the opening of the processing chamber to prevent the debris from leaking out. Traffic congestion clearing status: Shutdown: When it is observed that the discharge speed of the discharge hopper slows down significantly or no straw is discharged, it is determined that there is a blockage inside the processing chamber. Immediately turn off the geared motor and cut off the power to the equipment. Unlocking the compartment cover: The operator holds the pull ring of the easy-to-remove limit mechanism and pulls the lever away from the limit block. The lever drives the limit slide to compress the spring and move away from the arc-shaped slide groove until the limit head is completely disengaged from the limit hole of the arc-shaped slider, thus unlocking the compartment cover. Open the chamber cover: Hold the handle on the chamber cover and rotate the cover upwards using the hinge as the axis of rotation. The arc-shaped slider will slide along the arc-shaped groove until the chamber cover is fully opened, exposing the interior of the processing chamber. Unblocking operation: Use tools such as rakes and brushes to reach into the processing chamber and clear the straw blocking the area around the cutter, the connection between the feed hopper and the processing chamber, or the inlet of the discharge hopper; Reset the compartment cover: After clearing the blockage, hold the handle and flip the compartment cover downwards so that the arc-shaped slider slides back to the initial position along the arc-shaped slide groove. Release the pull ring, and the spring will return to its natural extension state. Push the limit slide and the limit head to reset. The limit head will be reinserted into the limit hole to complete the locking of the compartment cover. Restart the equipment: After confirming that the bin cover is locked, restart the geared motor and the equipment will resume normal straw recycling operation.
[0006] Compared with the prior art, the beneficial effects of this utility model are: Convenient and efficient unblocking: The bin cover can be quickly unlocked and locked through the easy-to-disassemble limit mechanism. No tools are needed. Just pull the ring to open the bin cover. The unblocking operation time is reduced by more than 60% compared with existing equipment, which greatly improves the straw recycling efficiency. Attached Figure Description

[0010] This implementation plan addresses the technical problems existing in the prior art, such as those disclosed in the background section above: "Currently, most straw recycling devices on the market include a straw chopping mechanism and a processing bin. The straw is chopped by the chopping mechanism and discharged from the discharge hopper. However, in actual use, due to the soft texture and varying lengths of the straw, blockages easily occur inside the processing bin or at the connection between the feed hopper, discharge hopper, and processing bin. Existing devices often use bolts or complex snap-fit structures for the processing bin cover. When blockage occurs, tools are needed to remove the bolts or unlock the complex snap-fits to open the cover." The process of clearing blockages is cumbersome and time-consuming, severely impacting straw recycling efficiency. Furthermore, some devices suffer from poor support stability, causing equipment to shake during clearing and further increasing the difficulty.
