Description

Technical Field

[0001] This invention belongs to the field of fireplace technology, specifically referring to a multifunctional indoor fireplace with real flame. Background Technology

[0002] A fireplace is a freestanding or wall-mounted indoor heating device that uses burning wood as its heat source, providing warmth and comfort. Because burning wood requires oxygen, the wood must be spaced out to prevent slow burning and extinguishing. Therefore, when lighting a fireplace, the wood must be manually arranged in a staggered pattern, and firewood is used to fuel the flame and ignite the logs. This entire process requires manual operation, causing inconvenience and making fireplaces impractical.

[0003] Furthermore, existing fireplaces are not very effective at heating, only providing warmth in a small area near the fireplace through heat dissipation, and therefore cannot produce a good effect on overall indoor heating. Summary of the Invention

[0004] In view of the above situation and to overcome the defects of the prior art, the present invention provides a multifunctional indoor real fire fireplace, which is equipped with an automatic wood placement mechanism, solving the problem of manual wood loading and placement in the prior art. It also has a staggered wood placement function, solving the problem of poor combustion effect due to poor placement position; and has a high-efficiency heating effect, solving the problem of small heating range.

[0005] The technical solution adopted by this invention is as follows: This invention provides a multifunctional indoor fireplace with a real flame, comprising: a fireplace body, the fireplace body being a cavity; a wood box for storing wood, the wood box being disposed on one side of the fireplace body; and an automatic placement mechanism, the automatic placement mechanism being disposed close to the fireplace body and the wood box. The automatic placement mechanism includes a placement support frame, a drive rod, a drive slider, a linkage arm, a linkage rod, a linkage slider, a telescopic arm, a top slide rod, and a pickup frame. The placement support frame is T-shaped, the bottom of the linkage arm is hinged to the placement support frame, the linkage arm has a downward groove, the drive slider is slidably disposed in the downward groove, the drive rod is rotatably disposed on the placement support frame, a pickup motor is connected to the drive rod, the drive rod and the drive slider are hinged, the placement support frame has an extension frame, the linkage rod is rotatably disposed on the extension frame, the linkage arm has an upper sliding groove, the linkage slider is slidably disposed in the upper sliding groove, and the linkage rod... The structure, hinged to the linkage slider, allows the following function: when the drive rod rotates, the vertical force is counteracted by the sliding slider within the sliding groove, thus propelling the linkage arm to reciprocate. Similarly, the linkage arm acts in the opposite direction on the linkage slider, causing the linkage rod to reciprocate. A swing sleeve is rotatably mounted on the extension frame, coaxially connected to the linkage rod. The telescopic arm slides within the swing sleeve, has a limiting block, and a spring is fitted onto it, located between the limiting block and the swing sleeve. The top slide rod is positioned at the top of the placement support frame, with a transverse slide sleeve sliding on it and a longitudinal slide rod on the transverse slide sleeve. The picking frame slides on the longitudinal slide rod, resulting in a movement where the picking frame moves up and down on one side and then slides to the other side to move up and down, thus achieving automatic picking and placing of wood. The gripper is equipped with an elastic telescopic rod on the picking frame. The gripper is mounted on the elastic telescopic rod. The function of the elastic telescopic rod is to enable the gripper to grip wood at different depths. Under the control of the automatic placement mechanism, the gripper is driven to rotate between the wood box and the furnace body to pick up wood and realize the function of automatic feeding. The shredder is used to crush large pieces of wood and pour the crushed wood chips into the furnace body, which helps to quickly ignite and increase the fire during the initial ignition, thereby facilitating the rapid ignition of the main wood material and having a combustion-supporting effect.

[0006] Furthermore, to simultaneously grasp multiple pieces of wood, the gripper includes a housing, a guide slide plate, a connecting slide rod, a clamping arm, and a pickup chuck. The housing is hollow with an opening at the bottom. Vertical slide rails are provided on both sides inside the housing, and a horizontal slide rail is provided inside the housing. The guide slide plate slides on the vertical slide rails, and the connecting slide rod slides on the horizontal slide rails. The connecting slide rod is located inside the guide slide plate. The guide slide plate has multiple hollow guide grooves, which are inclined and converge towards the center. The connecting slide rod has a sliding head that slides within the hollow guide grooves. The clamping arm and the connecting slide rod are fixedly connected, and the pickup chuck is fixedly mounted on the clamping arm.

[0007] Furthermore, the picking clamp is provided with a clamping groove to facilitate clamping round pieces of wood. Since the wood is stacked in a wood box, the bottom of the picking clamp is pointed so that it can be inserted between the pieces of wood to facilitate the removal of the wood from the stack. This makes it easier to pick up multiple pieces of wood from the wood box at the same time.

[0008] Furthermore, a gripping screw is rotatably provided inside the housing, the gripping screw is threadedly connected to the guide slide plate, and a gripping motor is provided on the housing, the gripping motor being connected to the gripping screw.

[0009] Furthermore, the furnace body is equipped with a partition, which divides the space inside the furnace into upper and lower chambers: an upper combustion chamber and a lower ash collection chamber. To ensure that the fuel wood has gaps when placed, a perforated plate is rotatably mounted on the partition. The perforated plate has ash collection holes, and the partition is a cavity. A toothed ring is located on the outer side of the perforated plate, and a placement gear is rotatably mounted inside the partition. The placement gear meshes with the toothed ring, and a placement motor is connected to the placement gear. The placement motor is equipped with a heat insulation cover. After the wood is placed on the perforated plate, the position of the wood is adjusted by controlling the rotation of the perforated plate, so that the wood placed later is staggered with the wood placed earlier, leaving gaps between the wood pieces to ensure sufficient air for combustion.

[0010] Furthermore, to facilitate the placement of wood into the furnace body, the top of the furnace body is open, while the furnace body needs to be sealed. Therefore, the furnace body is equipped with a sealing mechanism, which includes a sealing cover one, a sealing cover two, a push-pull rod one, a push-pull rod two, and an active push rod. The sealing cover one and the sealing cover two are hinged to the top of the furnace body. The push-pull rod one is hinged to the sealing cover one, and the push-pull rod two is hinged to the sealing cover two. One end of the active push rod is hinged to the furnace body, and the other end of the active push rod is hinged to the push-pull rod one and the push-pull rod two. The rotation of the active push rod can push and pull the sealing cover one and the sealing cover two through the push-pull rod one and the push-pull rod two, thereby opening or closing the furnace body.

[0011] Furthermore, when the automatic placement mechanism grabs the wood and places it into the furnace, both the first and second sealing covers on the furnace body should be open. After the wood is placed, the furnace body should be sealed. Since the reciprocating rotation of the active push rod can control the opening and closing of the furnace body's cover, the automatic placement mechanism's linkage arm also reciprocates when it moves back and forth to grab the wood. Therefore, the linkage arm and the active push rod are fixedly connected, meaning that when the linkage arm rotates, the active push rod rotates simultaneously. This achieves the linkage effect of placing and opening / closing when the grabber loses the wood and moves to the top of the furnace body.

[0012] Furthermore, in order to avoid placing push-pull rod one, push-pull rod two, and active push rod inside the high-temperature furnace body, an extension section is provided on sealing cover one and the sealing cover. Push-pull rod one, push-pull rod two, and active push rod are all located outside the furnace body. The extension section of push-pull rod one and sealing cover one are hinged together, and the extension section of push-pull rod two and sealing cover two are hinged together.

[0013] Furthermore, in order to make full use of waste wood, the waste wood is crushed and can be used as fuel material. The crusher includes a crushing box, a crushing shaft, and a crushing cover plate. The top of the crushing box is open, and the crushing cover plate is locked at the opening of the crushing box. The crushing cover plate has symmetrical crushing openings on both sides. The crushing shaft is rotatably located on both sides inside the crushing box and is located inside the crushing opening. The crushing shaft is equipped with crushing blades, and crushing grooves are provided on both sides of the crushing opening. The crushing grooves and crushing blades are staggered to ensure that the crushing shaft rotates smoothly inside the crushing opening. In order to prevent blockage during the crushing process, that is, to leave enough space for the wood material, the crushing blades are spirally arranged on the circumference of the crushing shaft. At the same time, due to the setting of the crushing cover plate, the material will not fall directly into the crushing box, thus achieving the function of fine crushing without blockage.

[0014] To further improve the anti-clogging effect of the crusher, the crushing shaft is controlled to reciprocate, thus avoiding clogging caused by rotation in one direction. Therefore, the crusher is equipped with a reciprocating drive assembly, which includes a forward gear, a reverse gear, a drive gear, a driven gear, a connecting gear one, and a connecting gear two. The forward gear and the reverse gear are rotatably arranged and mesh with each other. The forward gear is equipped with a forward lever, and the reverse gear is equipped with a reverse lever. The forward levers are evenly distributed along the circumference of the forward gear and mesh with the tooth grooves of the drive gear. The reverse levers are evenly distributed along the circumference of the reverse gear and mesh with the tooth grooves of the drive gear. The forward levers and the reverse levers do not mesh with the drive gear simultaneously. The drive gear, connecting gear one, connecting gear two, and driven gear mesh and transmit power in sequence.

[0015] The crushing disc has pointed tips on both sides, which facilitates crushing from both sides.

[0016] With the above structural design, firstly, by setting up spiral crushing blades, sufficient storage space is left between the two crushing shafts for the wood. The crushing trough, combined with the crushing blades and crushing cover plate, achieves crushing. At the same time, the two crushing shafts also have forward and reverse rotation functions, so that the wood is turned over by the two crushing shafts during crushing, further avoiding the possibility of blockage. Therefore, it can efficiently and without blockage crush large or irregular waste wood or other fuels, which can both reuse waste and serve as auxiliary fuel for the main wood material.

[0017] Furthermore, in order to facilitate the conveying of the crushed wood chips into the furnace body, the bottom of the crushing box is provided with a bottom conveying trough, the bottom conveying trough is connected to the lifting conveying trough, the bottom conveying trough is provided with a first conveying auger, and the lifting conveying trough is provided with a second conveying auger.

[0018] Furthermore, in order to transport the debris into the furnace body without obstructing or interfering with other structures and spaces, a telescopic feeding mechanism is provided between the crushing box and the furnace body. The telescopic feeding mechanism includes a fixed base frame, a drive frame, and a sliding upper frame. The fixed base frame is provided with a bottom slide rail, and the drive frame is slidably mounted on the bottom slide rail. Sprockets are rotatably mounted at both ends of the drive frame, and roller chains are connected to the sprockets. A telescopic motor is provided on the drive frame to drive the sprockets and control the rotation of the roller chains. The roller chains are provided with a lower fixing buckle, which is fixedly connected to the fixed base frame. The roller chains are provided with an upper fixing buckle, which is fixedly connected to the sliding upper frame. A feeding conveyor belt is provided on the sliding upper frame, and baffles are provided on both sides of the feeding conveyor belt. A discharge port is provided on the lifting conveyor trough, and the discharge port is connected to the feeding conveyor belt. The extension of both the drive frame and the sliding upper frame improves the telescopic effect, thereby increasing the feeding range of the conveyor belt. To enhance the connection stability between the sliding upper frame and the drive frame, an extension slide is slidably provided on the drive frame, and a connecting slide bar is provided on the sliding upper frame. The connecting slide bar and the extension slide bar are slidably connected. The connection bar and the extension slide bar improve the sliding stability between the sliding upper frame and the drive frame, preventing the sliding upper frame from sagging and hindering smooth sliding due to the small connection point when the sliding upper frame extends out of the drive frame.

[0019] Furthermore, the furnace body is equipped with a heating system, which includes a combustion air intake pipe, an exhaust pipe, and a heating pipe. The air intake pipe is connected to the ash collection chamber, the exhaust pipe is connected to the combustion chamber, and the heating pipe passes through the inner wall of the combustion chamber. The two ends of the heating pipe are located inside the chamber, and the two ends of the heating pipe are respectively the air intake and the exhaust. Both the air intake and the exhaust are equipped with filter covers. A fan is installed inside the heating pipe, and a filter is installed in the exhaust pipe.

[0020] The beneficial effects of the present invention using the above structure are as follows: The beneficial effects of the multifunctional indoor real fire fireplace provided by this solution are as follows: It has the function of automatically placing round logs, reducing manual labor; it can place round logs in an alternating manner to improve the combustion effect; it has the function of efficiently crushing waste wood, reusing waste; it has the function of efficiently heating; and the various structures are closely connected, with mutual assistance and synergistic effects.

[0021] Specifically: 1. Automatic placement mechanism, through reciprocating movement, works with a gripper to pick up logs from the timber box and place them into the furnace, thus realizing the function of automatic feeding.

[0022] 2. The gripper has the function of gripping multiple pieces of wood at the same time, achieving efficient, fast and accurate feeding.

[0023] 3. The perforated panels on the partition have a rotating function, automatically adjusting their angle and position, allowing the wood to be placed in an alternating manner, thus leaving sufficient gaps between the wood.

[0024] 4. The sealing mechanism has the function of controlling the opening and closing of the furnace body, and is linked with the automatic placement mechanism. It automatically opens when placing wood and automatically closes after placement, realizing the function of automatic opening and closing.

[0025] 5. The crusher crushes waste wood, reusing the wood and also aiding combustion. The spiral-shaped crushing blades on the crushing shaft of the crusher have an anti-clogging function, and the reciprocating drive component further improves the anti-clogging effect.

[0026] 6. The telescopic feeding mechanism has a multi-stage telescopic function, which reduces the space occupied and increases the conveying range, making it convenient to transport wood chips.

[0027] 7. It has a highly efficient heating system that can quickly raise the indoor temperature without causing indoor pollution. Attached Figure Description

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0031] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0032] like Figure 1-12 As shown, the present invention provides a multifunctional indoor fireplace with a real flame, such as... Figure 1 The system includes a furnace body 1, which is a hollow cavity. The furnace body 1 can be installed within a wall or placed indoors as a finished product. The furnace body 1 contains vermiculite slabs and a furnace door with high-temperature resistant glass. The furnace body 1 is coated with high-temperature resistant paint. A timber box 2 is used to store timber and is located on one side of the furnace body 1. An automatic placement mechanism 3 is positioned near the furnace body 1 and the timber box 2. Figure 2-3The automatic placement mechanism 3 includes a placement support frame 4, a drive rod 5, a drive slider 6, a linkage arm 7, a linkage rod 8, a linkage slider 9, a telescopic arm 10, a top slide rod 11, and a pickup sleeve 12. The placement support frame 4 is T-shaped. The bottom of the linkage arm 7 is hinged to the placement support frame 4. The linkage arm 7 has a sliding groove 13, and the drive slider 6 is slidably disposed in the sliding groove 13. The drive rod 5 is rotatably disposed on the placement support frame 4, and a pickup motor 14 is connected to the drive rod 5. The drive rod 5 and the drive slider 6 are hinged. The placement support frame 4 has an extension frame 15, and the linkage rod 8 is rotatably disposed on the extension frame. On the extension frame 15, the linkage swing arm 7 is provided with an upper sliding groove 16, and the linkage slider 9 is slidably disposed in the upper sliding groove 16. The linkage rotating rod 8 and the linkage slider 9 are hinged. The above structure can produce the following effect: when the driving rotating rod 5 rotates, the vertical force is counteracted by the sliding of the driving slider 6 in the lower sliding groove 13, thereby pushing the linkage swing arm 7 to perform a reciprocating swinging motion. Similarly, the linkage swing arm 7 acts in the opposite direction on the linkage slider 9, and drives the linkage rotating rod 8 to perform a reciprocating swinging motion. The extension frame 15 is rotatably provided with a swinging sleeve 17, and the swinging sleeve 17 and the linkage rotating rod 8 are coaxially connected. The telescopic swing arm 10 is slidably disposed in the swinging sleeve 17. A limiting block 18 is provided on the telescopic swing arm 10, and a spring 19 is sleeved on the telescopic swing arm 10. The spring 19 is located between the limiting block 18 and the swing sleeve 17. The top slide rod 11 is located at the top position on the placement support frame 4. A transverse slide sleeve 20 is slidably provided on the top slide rod 11, and a longitudinal slide rod 21 is provided on the transverse slide sleeve 20. The pickup sleeve 12 is slidably provided on the longitudinal slide rod 21. The working principle of the above structure is that when the linkage rotating rod 8 rotates, the swing sleeve 17 also rotates. The swing sleeve 17 drives the telescopic swing arm 10 to swing. The telescopic swing arm 10 drives the pickup sleeve 12 to slide up and down on the longitudinal slide rod 21, and the longitudinal slide rod... 21. The horizontal sliding sleeve 20 slides laterally on the top sliding rod 11; the gripper 22 is provided with an elastic telescopic rod 23 on the picking frame 12, and the gripper 22 is set on the elastic telescopic rod 23. The function of the elastic telescopic rod 23 is to enable the gripper 22 to grab wood at different depths. Under the control of the automatic placement mechanism 3, the gripper 22 is driven to rotate between the wood box 2 and the furnace body 1 to pick up wood and realize the function of automatic feeding; the shredder 24 is used to crush large pieces of wood and pour the crushed wood chips into the furnace body 1, which is conducive to rapid ignition and increased flame during initial ignition, and thus facilitates the rapid ignition of the main material wood, and has a combustion-supporting effect.

[0033] To achieve the simultaneous grabbing of multiple pieces of timber, such as Figure 4The gripper 22 includes a housing 25, a guide slide plate 26, a connecting slide rod 27, a gripping arm 29, and a pickup chuck 28. The housing 25 is a cavity with an opening at the bottom. Vertical slide rails 30 are provided on both sides inside the housing 25, and a horizontal slide rail 31 is provided inside the housing 25. The guide slide plate 26 is slidably mounted on the vertical slide rails 30, and the connecting slide rod 27 is slidably mounted on the horizontal slide rail 31. The connecting slide rod 27 is located inside the guide slide plate 26. The guide slide plate 26 has multiple hollow guide grooves 32, which are inclined and converge towards the center. The connecting slide rod 27 has a sliding head 33. 3. Slidingly disposed within the hollow guide groove 32, the clamping arm 29 and the connecting slide rod 27 are fixedly connected, the picking chuck 28 is fixedly disposed on the clamping arm 29, the picking chuck 28 is provided with a clamping groove 34 to facilitate clamping round wood, and since the wood is stacked in the wood box 2, in order to facilitate the removal of wood from the stacked wood, the bottom of the picking chuck 28 is pointed, which can be inserted between the wood, thereby facilitating the simultaneous removal of multiple pieces of wood from the wood box 2, a gripping screw 35 is rotatably disposed inside the outer shell 25, the gripping screw 35 is threadedly connected to the guide slide plate 26, a gripping motor 36 is disposed on the outer shell 25, and the gripping motor 36 is connected to the gripping screw 35.

[0034] The working principle of the above structure is as follows: the gripping motor 36 is started to drive the gripping screw 35 to rotate, which in turn drives the guide slide plate 26 to slide downward. Then, the hollow guide groove 32 on it drives the sliding head 33 to converge towards the center in sync, which in turn drives the clamping arm 29 to move in sync. Multiple round logs are clamped at the same time through the picking chuck 28.

[0035] Among them, such as Figure 6 The furnace body 1 is equipped with a partition 37, which divides the space inside the furnace body 1 into two chambers: an upper combustion chamber 38 and a lower ash collection chamber 39. To ensure that the fuel wood has gaps when placed, a perforated plate 40 is rotatably mounted on the partition 37. The perforated plate 40 has ash collection holes 41, and the partition 37 is a cavity. A toothed ring 42 is provided on the outer side of the perforated plate 40, and a placement gear 43 is rotatably mounted inside the partition 37. The placement gear 43 meshes with the toothed ring 42, and a placement motor 44 is connected to the placement gear 43. The placement motor 44 is equipped with a heat insulation cover. After the wood is placed on the perforated plate 40, the position of the wood is adjusted by controlling the rotation of the perforated plate 40, so that the subsequently placed wood and the previously placed wood are placed alternately, leaving gaps between the wood to ensure sufficient air for combustion.

[0036] To facilitate the placement of wood into furnace body 1, such as Figure 6The furnace body 1 has an open top and requires sealing. Therefore, a sealing mechanism 45 is provided on the furnace body 1. The sealing mechanism 45 includes a sealing cover 46, a sealing cover 47, a push-pull rod 48, a push-pull rod 49, and an active push rod 50. The sealing cover 46 and the sealing cover 47 are hinged to the top of the furnace body 1. The push-pull rod 48 is hinged to the sealing cover 46, and the push-pull rod 49 is hinged to the sealing cover 47. One end of the active push rod 50 is hinged to the furnace body 1, and the other end of the active push rod 50 is hinged to the push-pull rod 48 and the push-pull rod 49. The rotation of the active push rod 50 can push and pull the sealing cover 46 and the sealing cover 47 through the push-pull rod 48 and the push-pull rod 49, thereby opening or closing the furnace body 1.

[0037] Furthermore, when the automatic placement mechanism 3 grabs the wood and places it into the furnace body 1, the sealing cover 46 and sealing cover 47 on the furnace body 1 should be in the open state. After the wood is placed, the furnace body 1 should be in a sealed state. Since the reciprocating rotation of the active push rod 50 can control the opening and closing of the cover of the furnace body 1, the automatic placement mechanism 3 also reciprocates and swings its linkage arm 7 when it moves back and forth to grab the wood. Therefore, the linkage arm 7 and the active push rod 50 are fixedly connected. That is, when the linkage arm 7 rotates, the active push rod 50 rotates at the same time. This achieves the effect of the automatic placement mechanism 3 opening the sealing cover on the furnace body 1 when the grabber 22 loses the wood and moves to the top of the furnace body 1, making it easy to put the wood into the furnace body 1. This achieves the linkage effect of placement and opening / closing.

[0038] To avoid placing the push-pull rod 48, push-pull rod 49, and active push rod 50 inside the high-temperature furnace body 1, an extension section 51 is provided on the sealing cover 46. The push-pull rod 48, push-pull rod 49, and active push rod 50 are all located outside the furnace body 1. The extension section 51 of the push-pull rod 48 and the sealing cover 46 are hinged together, and the extension section 51 of the push-pull rod 49 and the sealing cover 47 are hinged together.

[0039] In order to make full use of waste wood, it is shredded and can be used as a fuel for combustion, such as... Figure 7 The crusher 24 includes a crushing box 52, a crushing shaft 53, and a crushing cover plate 54. The crushing box 52 has an opening at the top, and the crushing cover plate 54 is fitted into the opening of the crushing box 52. The crushing cover plate 54 has symmetrically arranged crushing openings 55 on both sides. The crushing shaft 53 is rotatably disposed on both sides inside the crushing box 52, and is located within the crushing openings 55. The crushing shaft 53 has crushing blades 56. Crushing grooves 57 are provided on both sides of the crushing openings 55. The crushing grooves 57 and crushing blades 56 are staggered to ensure smooth rotation of the crushing shaft 53 within the crushing openings 55. To prevent blockage during the crushing process, sufficient space is provided for the wood material. Therefore, as... Figure 9The crushing discs 56 are arranged in a spiral on the circumference of the crushing shaft 53. At the same time, due to the setting of the crushing cover plate 54, the material will not fall directly into the crushing box 52, thus achieving the function of fine crushing without clogging. The crushing discs 56 are provided with pointed heads 58 on both sides.

[0040] To further improve the anti-clogging effect of the crusher, the reciprocating rotation of the crushing shaft 53 can be controlled to avoid clogging problems caused by rotation in one direction. Figure 9 Therefore, the crusher 24 is provided with a reciprocating drive assembly 59, which includes a forward gear 60, a reverse gear 61, a drive gear 62, a driven gear 63, a first connecting gear 64, and a second connecting gear 65. The forward gear 60 and the reverse gear 61 are rotatably arranged and mesh with each other. The forward gear 60 is provided with a forward lever 66, and the reverse gear 61 is provided with a reverse lever 67. The forward lever 66 is evenly arranged along the circumference of the forward gear 60 and meshes with the tooth groove of the drive gear 62. The reverse lever 67 is evenly arranged along the circumference of the reverse gear 61 and meshes with the tooth groove of the drive gear 62. The forward lever 66 and the reverse lever 67 do not mesh with the drive gear 62 at the same time. The drive gear 62, the first connecting gear 64, the second connecting gear 65, and the driven gear 63 mesh and drive in sequence. The crushing motor 68 is connected to the drive gear 62.

[0041] The working principle of the above structure is as follows: The forward gear 60 rotates forward, causing the reverse gear 61 and forward gear 60 to rotate in opposite directions. When the forward lever 66 engages with the drive gear 62, it drives the drive gear 62 to rotate in opposite directions. When the reverse lever 67 engages with the drive gear 62, it drives the drive gear 62 to rotate forward, thus controlling the cyclic forward and reverse rotation of the drive gear 62. Through the transmission of connecting gear 1 64 and connecting gear 2 65, the driven gear 63 is driven to rotate in the cyclic forward and reverse directions, with the drive gear 62 and driven gear 63 rotating in opposite directions. Then, the drive gear 62 is connected to one crushing shaft 53, and the driven gear 63 is connected to another crushing shaft 53, resulting in a cyclic forward and reverse rotation effect between the two crushing shafts 53. The forward and reverse rotation described above do not refer to a fixed direction, but rather to indicate the transmission between gears and whether their rotation directions are the same or opposite.

[0042] To facilitate the conveying of the shredded wood chips into furnace body 1, such as Figure 1 The bottom of the crushing box 52 is provided with a bottom conveying trough 69, which is connected to the lifting conveying trough 70. The bottom conveying trough 69 is provided with a first conveying auger 71, and the lifting conveying trough 70 is provided with a second conveying auger 72.

[0043] Furthermore, in order to transport the debris into the furnace body 1 without obstructing or interfering with other structures and spaces, such as... Figure 10-11 A telescopic feeding mechanism 73 is provided between the crushing box 52 and the furnace body 1. The telescopic feeding mechanism 73 includes a fixed base frame 74, a drive middle frame 75, and a sliding upper frame 76. A bottom slide rail 77 is provided on the fixed base frame. The drive middle frame 75 is slidably mounted on the bottom slide rail 77. Sprockets 78 are rotatably mounted at both ends of the drive middle frame 75. Roller chains 79 are connected to the sprockets 78. A telescopic motor 80 is provided on the drive middle frame 75 to drive the sprockets 78 to control the rotation of the roller chains 79. A lower fixing buckle 81 is provided on the roller chains 79. The lower fixing buckle 81 is fixedly connected to the fixed base frame 74. An upper fixing buckle 82 is provided on the roller chains 79. The upper fixing buckle 82 is fixedly connected to the sliding upper frame 76. A feeding conveyor belt 83 is provided on the sliding upper frame 76. A guardrail 84 is provided on both sides of the feeding conveyor belt 83. A discharge port is provided on the lifting conveyor trough 70 and is connected to the feeding conveyor belt 83.

[0044] Wood chips are conveyed onto the feeding conveyor belt 83 via the bottom conveyor 69 and the lifting conveyor 70. Activating the telescopic motor 80 rotates the sprocket 78, which in turn rotates the roller chain 79. Because the lower fixing buckle 81 engages with the fixed base frame 74, the roller chain 79 causes the drive frame 75 to extend slidably. Furthermore, the roller chain 79 causes the sliding upper frame 76 to extend, moving the feeding conveyor belt 83 to the upper part of the furnace body 1. The feeding conveyor belt 83 then conveys the wood chips into the furnace body 1. An extension carriage is slidably mounted on the drive frame 75, and a connecting slide bar is mounted on the sliding upper frame. The connecting slide bar and the extension carriage are slidably connected.

[0045] like Figure 12 The furnace body 1 is equipped with a heating system, which includes an air inlet pipe 85, an exhaust pipe 86, and a heating pipe 87. The air inlet pipe 85 is connected to the ash collection chamber 39, the exhaust pipe 86 is connected to the combustion chamber 38, and the heating pipe 87 passes through the inner wall of the combustion chamber. The two ends of the heating pipe 87 are located inside the chamber, and the two ends of the heating pipe 87 are respectively an air inlet 88 and an exhaust outlet 89. Both the air inlet 88 and the exhaust outlet 89 are equipped with filter covers. A fan is installed inside the heating pipe 87, and a filter is installed in the exhaust pipe 86. The fan transports cold air from inside the chamber to the heating pipe 87. After passing through the heating pipe 87, the cold air absorbs heat from inside the furnace body 1 and is then discharged from the exhaust outlet 89, thus achieving efficient heating.

[0046] Both the intake pipe 85 and the exhaust pipe 86 are bends to prevent fires.

[0047] A dust collection box is installed inside the dust collection chamber 39.

[0048] In practical use, the entire device is equipped with a control circuit. When fuel wood is placed in the wood box 2, the pickup motor 14 is started, driving the drive rod 5 to rotate. During this process, the drive slider 6 slides within the sliding groove 13, pushing the linkage arm 7 to reciprocate. Similarly, the linkage arm 7 acts in the opposite direction on the linkage slider 9, causing the linkage slider 9 to slide and driving the linkage rod 8 to reciprocate. When the linkage rod 8 rotates, the swing sleeve 17 also rotates, driving the telescopic swing arm 10 to also swing. The telescopic swing arm 10 drives the pickup frame 12 to slide up and down on the longitudinal slide rod 21. The rod 21 slides laterally on the top slide rod 11 via the transverse sliding sleeve 20, thereby enabling the gripper 22 to transfer wood between the wood box 2 and the furnace body 1. When the gripper 22 is working, the gripping motor 36 is started to drive the gripping screw 35 to rotate, which in turn drives the guide slide plate 26 to slide downward. The hollow guide groove 32 on it drives the sliding head 33 to converge towards the center synchronously, which in turn drives the clamping arm 29 to move synchronously. Multiple round logs are clamped at the same time by the picking chuck 28, and the elasticity of the elastic telescopic rod 23 pushes the gripper 22 to extend downward and grab the wood deep inside. While the linkage arm 7 swings back and forth, it controls the reciprocating movement of the picker between the wood box 2 and the furnace body 1. Simultaneously, the linkage arm 7 also rotates the active push rod 50. The active push rod 50, through push-pull rod 48 and push-pull rod 49, pushes and pulls the sealing cover 46 and sealing cover 47, thereby opening or closing the furnace body 1. When the picker 22 places wood into the furnace body 1, the furnace body 1 opens; after placement, the furnace body 1 closes. After a set of wood is placed on the perforated plate 40, the placement motor 44 is started, driving the placement gear 43 to rotate, which in turn drives the gear ring 42 and the perforated plate 40 to rotate, thus changing the position and angle of the wood. This causes the next set of wood to be placed to be staggered with the previously placed wood, increasing the gaps between the wood and facilitating combustion.

[0049] In use, waste wood can be put into the crusher for crushing. The crushing process is as follows: the forward gear 60 is driven to rotate forward, and then the reverse gear 61 and the forward gear 60 rotate in reverse. When the forward lever 66 and the drive gear 62 are engaged, the drive gear 62 is driven to rotate in reverse. When the reverse lever 67 and the drive gear 62 are engaged, the drive gear 62 is driven to rotate forward. This controls the cyclic forward and reverse rotation of the drive gear 62. Through the transmission of the connecting gear 1 64 and the connecting gear 2 65, the driven gear 63 is driven to rotate in the cyclic forward and reverse. The drive gear 62 and the driven gear 63 rotate in opposite directions, driving the crushing shaft 53 to reciprocate forward or reverse. Both ends of the crushing disc 56 on it can crush wood.

[0050] The crushed wood chips are conveyed to the feeding conveyor belt 83 through the bottom conveyor 69 and the lifting conveyor 70. By starting the telescopic motor 80, the sprocket 78 is rotated, which in turn drives the roller chain 79 to rotate. Because the lower fixing buckle 81 and the fixed base frame 74 are fixed, the roller chain 79 drives the drive frame 75 to slide out. The roller chain 79 further drives the sliding upper frame 76 to extend, moving the feeding conveyor belt 83 to the upper part of the furnace body 1. The feeding conveyor belt 83 conveys the wood chips into the furnace body 1. After the main material, round wood, is placed, the wood chips are added. This has a combustion-aiding effect and facilitates the combustion of the round wood. In specific use, an igniter can be used for ignition.

[0051] The fan delivers the cool air from the room to the heating pipe 87. After passing through the heating pipe 87, the cool air absorbs heat from the furnace body 1 and is then discharged from the exhaust port 89, thus converting the heat and increasing the temperature in the room. It also allows the air to circulate and is filtered and purified.
