Abstract
Description
Technical Field
[0001] This utility model relates to the field of feeding technology, and more specifically, to a feeding mechanism for a biofuel pellet mill. Background Technology
[0002] In existing technologies, the feeding mechanism of a biofuel pellet mill typically consists of a feeding hopper, a conveying component, and a feeding outlet connected to the pellet forming cavity. Its main function is to uniformly and stably feed the crushed biomass raw materials into the forming cavity to ensure the quality of pellet fuel compression molding.
[0003] First, the feed outlet is prone to blockage during operation. Biomass raw materials are usually characterized by high fiber content, large fluctuations in moisture content, and uneven particle size. They are prone to accumulating at the outlet during transportation, causing blockage. Once the outlet is blocked, the raw material cannot smoothly enter the molding cavity, which will not only affect the continuous production efficiency of the equipment, but may also cause the raw material to backflow and compact in the feed hopper or conveying channel, increasing the difficulty of cleaning.
[0004] Secondly, the connection and disassembly of the feed hopper and the external feeding equipment are not convenient enough. In traditional designs, the interface of the feed hopper is mostly a fixed structure, lacking the function of quick assembly and disassembly. When equipment maintenance, clearing blockages or replacing the feeding equipment are required, operators often need to use tools to disassemble it. The operation steps are cumbersome and time-consuming, which is not conducive to the efficient operation of the equipment. Especially in scenarios with large production scale or high requirements for continuous production, this inconvenient connection method will significantly increase downtime and reduce overall production efficiency. Utility Model Content

[0008] To achieve the above objectives, this utility model provides the following technical solution: a feeding mechanism for a biofuel pellet mill, comprising a feeding hopper, a discharge hammer mechanism, an external connection mechanism, and a clamping auxiliary mechanism. The discharge hammer mechanism includes a hydraulic cylinder and a rotating frame. The hydraulic cylinders are symmetrically installed on both sides of the feeding hopper. A discharge pipe is provided at the bottom end of the feeding hopper. The rotating frame is rotatably disposed on the side of the feeding hopper. One end of the hydraulic cylinder is rotatably connected to the rotating frame. An elastic plate is installed on the rotating frame. A hammer-receiving plate is installed on the side of the discharge pipe. The elastic plate is intermittently in contact with the elastic plate. The external connection mechanism includes a clamping pipe and a clamping rod. An internal toothed ring is rotatably installed on the upper limit of the side wall of the clamping pipe. A clamping tooth plate is rotatably installed on the upper limit of the side wall of the clamping pipe. A connecting tooth is meshed between the clamping tooth plate and the internal toothed ring. A clamping groove is opened on the outer wall of the clamping rod. The clamping tooth plate can rotate into or away from the clamping groove.
[0009] The present invention is further configured such that the snap-fit auxiliary mechanism includes an outer rotating ring and a longitudinal moving ring. The outer rotating ring is rotatably limited and mounted on the outer wall of the snap-fit tube. A spring plate is installed on the longitudinal moving ring. A ratchet ring is installed on one end face of the inner toothed ring. The longitudinal moving ring can be embedded in the ratchet ring, so that the spring plate contacts and supports the ratchet ring, so that the inner toothed ring is fixed in one direction, thereby fixing the embedded plate in the snap-fit groove.
[0010] The present invention is further configured such that a support plate is installed on the side of the feed hopper, and the clamping pipe is fixed to the bottom end face of the support plate.
[0011] The present invention is further configured such that a limiting block is installed at one end of the locking rod, and one end of the locking rod can pass through the external device and engage with the support plate and locking tube.
[0012] The present invention is further configured such that a valve assembly is installed between the feed hopper and the discharge pipe, and the rotating frame is supported and rotated on the side of the valve assembly.
[0013] The present invention is further configured such that a connecting plate is installed at the bottom end of the side wall of the card tube, and the connecting plate is fixedly installed on the bottom end face of the support plate.
[0014] The present invention is further configured such that a support base is installed on the side of the valve assembly, and the rotating frame is rotatably mounted on the support base.
[0015] The present invention is further configured such that a threaded plate is installed on one end face of the outer rotating ring, and the threaded plate is threadedly connected to the longitudinal moving ring.
[0016] (III) Beneficial Effects
[0017] Compared with the prior art, this utility model provides a feeding mechanism for a biofuel pellet mill, which has the following beneficial effects:
[0018] This utility model is equipped with a discharge hammer shaking mechanism. The discharge hammer shaking mechanism drives the rotating frame through a hydraulic cylinder, so that the elastic plate and the hammer plate make intermittent contact to generate periodic vibration impact. The vibration mechanism effectively prevents biofuel raw materials from clumping and sticking in the feed hopper, ensuring smooth material flow. The valve assembly and the support seat provide stable support, realizing precise control of material flow and continuous and stable supply.
[0019] This utility model is equipped with an external connection mechanism, which enables a quick and reliable connection between the feeding mechanism and the external equipment. The clamping tube is driven by the meshing of the internal toothed ring and the clamping plate, allowing the clamping plate to rotate into or away from the clamping groove of the clamping rod, thus achieving a plug-in connection. The support plate and the connecting plate provide a stable installation foundation, and the limiting block ensures precise positioning of the connection, improving the convenience and reliability of equipment connection and disassembly.
[0020] This utility model is equipped with a snap-fit auxiliary mechanism, which provides precise control and stable locking function for external connection. The outer rotating ring is threadedly connected to the longitudinal moving ring through a threaded plate to achieve precise longitudinal adjustment control. The spring plate on the longitudinal moving ring cooperates with the ratchet ring to form a one-way locking mechanism, which effectively prevents reverse rotation and accidental loosening during the connection process, ensuring that the snap-fit plate is stably fixed in the snap-fit groove, and guaranteeing the stability and safety of the connection.

[0030] Please see Figures 1-5 A feeding mechanism for a biofuel pellet mill includes a feeding hopper 1, a discharge hammer mechanism, an external connection mechanism, and a clamping auxiliary mechanism. The discharge hammer mechanism includes a hydraulic cylinder 2 and a rotating frame 3. The hydraulic cylinder 2 is symmetrically installed on both sides of the feeding hopper 1. A discharge pipe 4 is provided at the bottom end of the feeding hopper 1. The rotating frame 3 is rotatably arranged on the side of the feeding hopper 1. One end of the hydraulic cylinder 2 is rotatably connected to the rotating frame 3. An elastic plate 5 is installed on the rotating frame 3. A hammer receiving plate 6 is installed on the side of the discharge pipe 4. The elastic plate 5 is intermittently in contact with the other elastic plate 6. The external connection mechanism includes a clamping pipe 7 and a clamping rod 8. An internal toothed ring 9 is rotatably installed on the upper limit of the side wall of the clamping pipe 7. A clamping tooth plate 10 is rotatably installed on the upper limit of the side wall of the clamping pipe 7. A connecting tooth 11 is meshing between the clamping tooth plate 10 and the internal toothed ring 9. A clamping groove 12 is opened on the outer wall of the clamping rod 8. The clamping tooth plate 10 can rotate into or away from the clamping groove 12.
[0031] In this embodiment, the discharge hammer mechanism realizes the vibration, clearing, and directional discharge of material in the feed hopper 1. Hydraulic cylinders 2 are symmetrically installed on both sides of the feed hopper 1, providing driving power for the rotating frame 3. One end of the hydraulic cylinder 2 is rotatably connected to the rotating frame 3, driving the rotating frame 3 to rotate on the side of the feed hopper 1. The elastic plate 5 installed on the rotating frame 3 rotates with the frame body and intermittently contacts the hammer plate 6 on the side of the discharge pipe 4, generating vibration and impact. The periodic hammering vibration can effectively prevent the material from clumping and sticking in the feed hopper 1, ensuring that the material flows smoothly to the discharge pipe 4. The valve assembly 19 controls the material flow rate, and the support base 21 provides stable rotation for the rotating frame 3. The support and external connection mechanism enable reliable connection and quick assembly / disassembly between the feeding mechanism and external equipment. The clamping tube 7 is used to limit the rotation of the internal gear ring 9 and the clamping plate 10. The internal gear ring 9 and the clamping plate 10 are connected by meshing teeth 11 to form a transmission system. When connection is required, the clamping plate 10 rotates and extends into the groove 12 on the outer wall of the clamping rod 8 to form a mechanical clamping. A limiting block 18 is installed at one end of the clamping rod 8, which can pass through the external equipment and engage with the support plate 17 and the clamping tube 7. The connecting plate 20 is fixedly installed on the bottom end face of the support plate 17 to provide a stable installation base for the clamping tube 7 and ensure accurate positioning and reliable fixation during the connection process.
[0032] The locking auxiliary mechanism includes an outer rotating ring 13 and a longitudinal moving ring 14. The outer rotating ring 13 is rotatably mounted on the outer wall of the locking tube 7. A spring plate 15 is mounted on the longitudinal moving ring 14. A ratchet ring 16 is mounted on one end face of the inner toothed ring 9. The longitudinal moving ring 14 can be embedded in the ratchet ring 16, so that the spring plate 15 contacts and supports the ratchet ring 16, so that the inner toothed ring 9 is fixed in one direction, thereby fixing the embedded plate in the locking groove 12.
[0033] In this embodiment, the snap-fit auxiliary mechanism provides precise control and stable locking for the external connection. The outer rotating ring 13 is installed on the outer wall of the snap-fit tube 7 and is threadedly connected to the longitudinal moving ring 14 through the end face threaded plate 22 to achieve longitudinal adjustment control. The spring plate 15 installed on the longitudinal moving ring 14 can be embedded in the ratchet ring 16 on the end face of the inner toothed ring 9 and contact the ratchet ring 16 to form a one-way locking mechanism. When the outer rotating ring 13 rotates, the threaded transmission causes the longitudinal moving ring 14 to move. The spring plate 15 and the ratchet ring 16 cooperate to achieve one-way fixation of the inner toothed ring 9, thereby ensuring that the snap-fit plate 10 is stably fixed in the snap-fit groove 12, preventing accidental loosening and reversal during the connection process, and ensuring the stability and safety of the connection.
[0034] Please see Figures 1-5As a supplementary embodiment of the feeding mechanism of a biofuel pellet mill, which includes a discharge hammer shaking mechanism, an external connection mechanism, and a snap-fit auxiliary mechanism: A support plate 17 is installed on the side of the feeding hopper 1, a snap-fit pipe 7 is fixed to the bottom end face of the support plate 17, a limiting block 18 is installed at one end of the snap-fit rod 8, and one end of the snap-fit rod 8 can pass through an external device to engage with the support plate 17 and the snap-fit pipe 7. A valve assembly 19 is installed between the feeding hopper 1 and the discharge pipe 4, and a rotating frame 3 is rotatably supported on the side of the valve assembly 19. A connecting plate 20 is installed at the bottom end of the side wall of the snap-fit pipe 7, and the connecting plate 20 is fixedly installed on the bottom end face of the support plate 17.

A threaded plate 22 is installed on one end face of the outer rotating ring 13, and the threaded plate 22 is threadedly connected to the longitudinal moving ring 14.
[0035] More specifically, biofuel feedstock is fed into hopper 1 and gathers at the bottom under gravity. Hydraulic cylinder 2 starts to drive rotating frame 3 to rotate. Elastic plate 5 and hammer plate 6 intermittently contact to generate vibration, preventing material agglomeration and promoting flow. Valve assembly 19 adjusts the opening as needed to control the flow rate of material from hopper 1 to discharge pipe 4. Clamping rod 8 is inserted into external equipment, and clamping tooth plate 10 rotates and extends into clamping groove 12 to form a preliminary connection. Outer rotating ring 13 rotates to drive longitudinal moving ring 14 to move. Spring plate 15 contacts ratchet ring 16 to achieve one-way locking and ensure a stable connection. Under the action of vibration, material is continuously transported from hopper 1 to external equipment through discharge pipe 4 to achieve continuous and stable feeding supply.
[0036] In summary, during the use or operation of the overall equipment: when the discharge hammer mechanism is in operation, the discharge hammer mechanism realizes the vibration and dredging of the material in the feed hopper 1 and the directional discharge. The hydraulic cylinders 2 are symmetrically installed on both sides of the feed hopper 1 to provide driving power for the rotating frame 3. One end of the hydraulic cylinder 2 is rotatably connected to the rotating frame 3, driving the rotating frame 3 to rotate on the side of the feed hopper 1. The elastic plate 5 installed on the rotating frame 3 rotates with the frame and intermittently contacts the hammer plate 6 on the side of the discharge pipe 4 to generate vibration and impact. The periodic hammering vibration can effectively prevent the material from clumping and sticking in the feed hopper 1, ensuring that the material flows smoothly to the discharge pipe 4. The valve assembly 19 controls the material flow rate, and the support base 21 provides stable rotation support for the rotating frame 3.
[0037] When an external connection mechanism is required, it enables reliable connection and quick assembly / disassembly between the feeding mechanism and the external feeding equipment. The clamping tube 7 is used to limit the rotation of the internal gear ring 9 and the clamping plate 10. The internal gear ring 9 and the clamping plate 10 are connected by meshing teeth 11 to form a transmission system. When connection is required, the clamping plate 10 rotates and extends into the groove 12 on the outer wall of the clamping rod 8 to form a mechanical clamping. A limiting block 18 is installed at one end of the clamping rod 8, which can pass through the external equipment and engage with the support plate 17 and the clamping tube 7. The connecting plate 20 is fixedly installed on the bottom end face of the support plate 17 to provide a stable installation base for the clamping tube 7 and ensure accurate positioning and reliable fixation during the connection process.
[0038] When the locking auxiliary mechanism is required to operate, it provides precise control and stable locking for external connections. The outer rotating ring 13 is installed on the outer wall of the locking tube 7 and is threadedly connected to the longitudinal moving ring 14 through the end face threaded plate 22 to achieve longitudinal adjustment control. The spring plate 15 installed on the longitudinal moving ring 14 can be embedded in the ratchet ring 16 on the end face of the inner toothed ring 9 and forms a one-way locking mechanism by contacting and supporting the ratchet ring 16. When the outer rotating ring 13 rotates, the threaded transmission causes the longitudinal moving ring 14 to move. The spring plate 15 and the ratchet ring 16 cooperate to achieve one-way fixation of the inner toothed ring 9, thereby ensuring that the locking plate 10 is stably fixed in the locking groove 12, preventing accidental loosening and reversal during the connection process, and ensuring the stability and safety of the connection.
[0039] Biofuel feedstock is fed into hopper 1 and gathers at the bottom under gravity. Hydraulic cylinder 2 starts and drives rotating frame 3 to rotate. Elastic plate 5 and hammer plate 6 intermittently contact to generate vibration, preventing material agglomeration and promoting flow. Valve assembly 19 adjusts the opening as needed to control the flow rate of material from hopper 1 to discharge pipe 4.
