DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] like Figures 1 to 11 As shown, the present invention provides a feeding device for a biomass straw bale burning boiler, comprising a housing mechanism 1 composed of a limiting housing 101, a guide block 102 and a positioning plate 103, wherein the guide block 102 is fixedly mounted on the surface of the limiting housing 101, the positioning plate 103 is fixedly mounted inside the limiting housing 101, and a feeding bin 2 is also mounted on the surface of the limiting housing 101, and further comprising: A feeding mechanism 3, which is disposed inside the feed bin 2 and is used to feed the biomass straw bales into the limiting housing 101; A mechanical crushing mechanism 6, which is disposed in the limiting housing 101 and is used to crush the biomass straw bales; A pushing mechanism 4, which is arranged at one end of the limiting housing 101 away from the mechanical crushing mechanism 6 and is used to push the biomass straw bale toward the mechanical crushing mechanism 6; The positioning mechanism 5 is disposed inside the limiting housing 101 and is used to position the pushing mechanism 4; Among them, the pushing mechanism 4 includes a hydraulic cylinder 401, a first partition 402, a connecting rod 403, a second partition 404 and an air injection and crushing assembly 405. The first partition 402 and the second partition 404 are movable inside the limiting shell 101 and the two are connected by the connecting rod 403. The hydraulic cylinder 401 is installed at one end of the limiting shell 101 and the output end is fixedly connected to the first partition 402. The air injection and crushing assembly 405 is arranged in the middle of the second partition 404 and can be inserted into the middle of the biomass straw bale.

[0020] The above scheme is adopted: the biomass straw bale can fall into the limiting shell 101 through the rotation of the feeding mechanism 3, and the first partition plate 402, the connecting rod 403, the second partition plate 404 and the gas injection crushing component 405 can be driven to move synchronously through the hydraulic cylinder 401, and the gas injection crushing component 405 is inserted into the middle of the biomass straw bale and pushed toward the direction of the mechanical crushing mechanism 6. The positioning mechanism 5 is set to shorten the gas injection crushing component 405 when the two are in pressure contact. When the gas injection crushing component 405 is shortened, gas can be injected into the biomass straw bale, and the gap between the straws is enlarged by the gas, thereby promoting crushing, and the mechanical crushing mechanism 6 is set to crush one side of the biomass straw bale.

[0021] like Figures 3 to 6 As shown, the gas injection breaking assembly 405 includes a first connecting rod 4051, a second connecting rod 4052, a spring 4053 and a cone block 4054. The first connecting rod 4051 is fixedly connected to the first partition plate 402, the second connecting rod 4052 is sleeved on the surface of the first connecting rod 4051 and is slidably connected to the second partition plate 404, the spring 4053 is arranged inside the second connecting rod 4052 and shows a stretching tendency, the cone block 4054 is installed at one end of the second connecting rod 4052 away from the first partition plate 402, and a second slide groove is provided in an annular manner on the surface of the cone block 4054. When the cone block 4054 moves along its axial direction, the spring telescopic rod 503 can enter the second slide groove provided on the surface of the cone block 4054, and the second slide groove is arc-shaped.

[0022] The above scheme is adopted: the first connecting rod 4051 and the second connecting rod 4052 are in the longest state after being combined in a natural state through the provided spring 4053, and the provided cone block 4054 can be easily drilled into the inside of the biomass straw bale, and during the movement of the cone block 4054, the second sliding groove on its surface cooperates with the spring telescopic rod 503, so that the second connecting rod 4052 can rotate, and the rotation of the second connecting rod 4052 allows the spring telescopic block 453 to enter the first sliding groove 452 from the groove 451, thereby achieving the shortening of the overall length of the first connecting rod 4051 and the second connecting rod 4052. At this time, the second partition plate 404 can push the biomass straw bale on the surface of the second connecting rod 4052 to move toward the mechanical crushing mechanism 6 for crushing.

[0023] like Figure 6 , 7 As shown, a spring telescopic block 453 is annularly installed on the surface of the first connecting rod 4051 located at one end inside the second connecting rod 4052, and a slot 451 and a first slide slot 452 are provided on the inner wall of the second connecting rod 4052 for the spring telescopic block 453 to slide, and an exhaust hole 454 is annularly provided on the surface of one end of the second connecting rod 4052 close to the cone block 4054.

[0024] The above scheme is adopted: the spring telescopic block 453 located inside the first slide groove 452 in the initial state can play a locking effect, so that when the first partition plate 402 pushes the first connecting rod 4051, the first connecting rod 4051 will not enter the second connecting rod 4052, so that the second connecting rod 4052 can drill into the interior of the biomass straw bale. When the cone block 4054 is in pressure contact with the spring telescopic rod 503 and causes the second connecting rod 4052 to rotate, the movable end of the spring telescopic block 453 is squeezed by the second connecting rod 4052 and moves toward the fixed end. At this time, a gap is generated between the fixed end of the spring telescopic block 453 and the side wall of the slot 451. As the gap The first partition plate 402 continuously pushes the first connecting rod 4051 to move, so that the spring telescopic block 453 can enter the first slide groove 452. At this time, the first connecting rod 4051 gradually enters the second connecting rod 4052 along its axial direction. The gas injection crushing assembly 405 can discharge the air inside the second connecting rod 4052 into the biomass straw bale through the exhaust hole 454, and the gap between the straws is increased by gas, so that the crushing effect is better. At the same time, since the mechanical crushing mechanism 6 also crushes the biomass straw bale, the second partition plate 404 can squeeze the biomass straw bale so that it is always in contact with the mechanical crushing mechanism 6 for continuous crushing. The movement of the second partition 404 not only provides power for the movement of the biomass straw bales, but also can inject the air inside the limiting shell 101 into the furnace through the opening at the bottom of the limiting shell 101 to prevent dust from floating, and can also inject a certain amount of oxygen to promote combustion.

[0025] like Figure 7 As shown, the clamping slot 451 and the first sliding slot 452 are connected and there is a misalignment between the two, and the connection between the clamping slot 451 and the first sliding slot 452 on one side close to the movable end of the spring telescopic clamping block 453 is smooth.

[0026] The above scheme is adopted: when the spring telescopic block 453 is located inside the slot 451, the spring telescopic block 453 cannot be separated from the slot 451 when the second connecting rod 4052 does not rotate, so that the second connecting rod 4052 can be drilled into the biomass straw bale, thereby achieving the effect of separating the straw by injecting air from the inside; and because the slot 451 and the first slide slot 452 are misaligned and the connection on one side close to the active end of the spring telescopic block 453 is smooth, the spring telescopic block 453 can slide into the slot 451 through the first slide slot 452 under the elastic force of the spring 4053, thereby achieving convenient resetting of the structure and facilitating the crushing of the next bale.

[0027] like Figure 8 , 9 As shown in Figures 10, the mechanical crushing mechanism 6 includes a driving motor 601, a first gear 602, a second gear 603, a connecting ring 604 and a crushing disk 605. The driving motor 601 is fixedly mounted on the outer surface of the limiting housing 101. The output shaft of the driving motor 601 is transmission-connected to the connecting ring 604 through the first gear 602 and the second gear 603. A crushing disk 605 is fixedly mounted on one end of the connecting ring 604 away from the driving motor 601. The first gear 602, the second gear 603 and the connecting ring 604 are all rotatably connected to the positioning plate 103. The positioning mechanism 5 includes a connecting column 501, a supporting ring 502 and a spring telescopic rod 503. The connecting column 501 is fixedly connected to the inside of the limiting housing 101. The supporting ring 502 is sleeved on the surface of the connecting column 501. The spring telescopic rod 503 is annularly mounted on one end of the connecting column 501.

[0028] The above scheme is adopted: the biomass straw bale is torn and crushed by the rotation of the crushing disk 605. Since the positioning mechanism 5 needs to be aligned with the cone block 4054, the positioning mechanism 5 is set in the middle of the crushing disk 605. The positioning mechanism 5 is fixed. The spring telescopic rod 503 is telescopic and can adapt to the shape of the cone block 4054. The cone block 4054 is rotated by the movement of the spring telescopic rod 503 in the second slide groove, thereby driving the second connecting rod 4052 to rotate. Since the second connecting rod 4052 drills into the interior of the biomass straw bale, there is no straw in this area, so the crushing effect of the bale can be guaranteed.

[0029] like Figure 2 , 11As shown, the feeding mechanism 3 includes a rotating shaft 301, a partition plate 302, a guide frame 303 and a movable corner block 304. The rotating shaft 301 is slidably connected to the inside of the feed bin 2. The partition plate 302 is annularly fixed to the end surface of the rotating shaft 301 located inside the feed bin 2. The guide frame 303 is slidably connected to the limiting shell 101 and is rotatably connected to the rotating shaft 301. The movable corner block 304 is slidably connected to the bottom of the guide frame 303. The guide frame 303 is slidably connected to the guide block 102. The two adjacent partition plates 302 located below are both in contact with the inner wall of the feed bin 2. When the rotating shaft 301 and the guide frame 303 move upward as a whole, the partition plate 302 can rotate freely along the rotating shaft 301 inside the feed bin 2.

[0030] The above scheme is adopted: through the movement of the second partition plate 404 during the reset process from the mechanical crushing mechanism 6 to the direction of the hydraulic cylinder 401, the movable corner block 304 can be squeezed to move upward, and the upward movement of the movable corner block 304 can drive the rotating shaft 301 to move upward through the guide frame 303, thereby driving the partition plate 302 to move upward. The upward movement of the partition plate 302 will separate from the feed bin 2. At this time, the biomass straw bale located between the adjacent partition plates 302 can drive the partition plate 302 to rotate under the action of gravity, and the biomass straw bale falls into the limiting shell 101. When the second partition plate 404 passes over the movable corner block 304, the rotating shaft 301 descends and the partition plate 302 is in pressure contact with the feed bin 2 again. In this state, the partition plate 302 cannot rotate, which can also achieve the separation between the feed bin 2 and the limiting shell 101.

[0031] The working principle and use process of the present invention: When in use, the hydraulic cylinder 401 is started to push the first partition plate 402, the second partition plate 404 and the gas injection crushing assembly 405 to move synchronously in the direction close to the positioning mechanism 5. When the gas injection crushing assembly 405 moves, it can squeeze the movable corner block 304 to tilt upward inside the guide frame 303. During the movement of the gas injection crushing assembly 405, it drives the biomass straw bale to move and squeeze the crushing disk 605, and after the biomass straw bale cannot move, the cone block 4054 is used to make the second connecting rod 4052 drill into the biomass straw bale. At this time, the driving motor 601 is started to drive the crushing disk 605 to rotate through the first gear 602, the second gear 603 and the connecting ring 604 to crush the biomass straw bale. Synchronously, due to the hydraulic Driven by the pressure cylinder 401, the spring telescopic rod 503 falls into the second chute on the surface of the cone block 4054, and the cone block 4054 rotates under the pressure, and the rotation of the cone block 4054 drives the second connecting rod 4052 to rotate. The rotation of the second connecting rod 4052 enables the spring telescopic block 453 to enter the first chute 452 from the card slot 451. At this time, with the movement of the first partition 402 and the second partition 404, the first connecting rod 4051 gradually enters the second connecting rod 4052. Since there is a connecting rod 403 between the first partition 402 and the second partition 404, the second partition 404 will push the biomass straw bale along the surface of the second connecting rod 4052 to move in the direction of the crushing disk 605; Synchronously, when the first connecting rod 4051 enters the interior of the second connecting rod 4052, the air inside the second connecting rod 4052 can be squeezed out through the exhaust hole 454 to the spaces between the straws, thereby increasing the gaps between the straws and making the bale easier to break. When the biomass straw bale is broken, the driving motor 601 is stopped, and the first partition plate 402 and the second partition plate 404 are driven to return to their original positions through the hydraulic cylinder 401. In the process of returning to the original position, the spring 4053 provides elastic force all the time, so that the first connecting rod 4051 can be moved out of the interior of the second connecting rod 4052 first. After the spring telescopic block 453 enters the slot 451 through the first slide slot 452, it locks the first connecting rod 4051 and the second connecting rod 4052. When the second partition plate 404 is squeezed onto the movable corner block 304 during movement, the movable corner block 304 can be driven upward by pressure, thereby driving the guide frame 303 and the rotating shaft 301 upward, thereby eliminating the contact between the partition plate 302 and the feed bin 2. At this time, the biomass straw bales located between adjacent partition plates 302 can fall freely into the limiting shell 101 by gravity, thereby achieving a continuous crushing effect.
