[0030] Embodiment 1

[0031] Referring to Figure 1 - Figure 4 , which is the first embodiment of the present utility model. This embodiment provides a transmission device, including a conveying component 100. The conveying component 100 includes a lower carrier 101, an upper carrier 102 used in conjunction with the lower carrier 101, a rotating shaft 103 disposed between the lower carrier 101 and the upper carrier 102. The lower carrier 101 and the upper carrier 102 are connected by the rotating shaft 103, so that the upper carrier 102 can rotate through the rotating shaft 103, and a blanking member 104 disposed in the upper carrier 102 is used to blank the solid fuel;

[0032] The vibration assembly 200 includes a mounting frame 201 disposed on the lower carrier 101. The mounting frame 201 is fixedly installed at the bottom end of the inner wall of the lower carrier 101, a rack 202 and a rotating rod 203 disposed on the mounting frame 201. The rack 202 is slidably installed on the mounting frame 201, and a rotating member 204 is disposed on the rotating rod 203. Through the rotating member 204, the solid fuel can completely fall without accumulation.

[0033] The cleaning assembly 300 includes a rotating block 301 disposed on the upper carrier 102, a connecting member 302 disposed between the rotating block 301 and the lower carrier 101. By pulling the connecting member 302, the rotating block 301 rotates. One end of the connecting member 302 is rotatably installed on the upper carrier 102, and the other end is inserted into the rotating block 301, a counterweight block 303 disposed on the rotating block 301, a cross plate 304 disposed on the upper carrier 102, and a cleaning member 305 disposed on the cross plate 304. Through the cleaning member 305, the inside of the storage bin 104a is cleaned.

[0034] The fixing assembly 400 includes a concave frame 401 disposed on the lower carrier 101, an extension block 402 disposed in the concave frame 401. The extension block 402 is slidably installed inside the concave frame 401. A second spring (not labeled in the figure) is fixedly connected between the opposite surfaces of the two extension blocks 402. Through the second spring, the two extension blocks 402 can be reset, a locking block 403 disposed on the extension block 402, a rectangular block 404 disposed on the lower carrier 101 and the upper carrier 102, and an extrusion member 405 disposed on the concave frame 401.

[0035] Specifically, the blanking member 104 includes a storage bin 104a disposed inside the upper carrier 102 for storing solid fuel, and an electric telescopic rod 104b disposed inside the lower carrier 101. There are two electric telescopic rods 104b.

[0036] Further, the storage bin 104a is installed on the output ends of the two electric telescopic rods 104b through a hinge seat. By driving the two electric telescopic rods 104b, one side of the storage bin 104a rises. The lower carrier 101 and the upper carrier 102 are communicatively arranged. A groove 105 is formed on one side of the lower carrier 101 and is directly above the rotating shaft 103. A box door is hinged on one side of the storage bin 104a close to the groove 105, and the solid fuel is discharged from the box door.

[0037] Further, the rotating member 204 includes a gear 204a and a rubber block 204b disposed on the rotating rod 203. Torsion springs (not labeled in the figure) are disposed on both sides of the rotating rod 203. The rubber block 204b has flexibility, such as Figure 3 - to Figure 4, the top of the rubber block 204b is bent due to the extrusion of the storage bin 104a. There are several rubber blocks 204b arranged at equal intervals. A traction member is rotatably connected between the top of the rack 202 and one side of the bottom of the storage bin 104a. When the storage bin 104a rotates, it will also pull the traction member upward, and the rack 202 is pulled upward through the traction member. There are no teeth provided at the top and bottom of the side of the rack 202 close to the gear 204a, and the rack 202 does not mesh with the gear 204a in its initial state.

[0038] Furthermore, a handle is provided on one side of the upper carrier 102, and a number of universal wheels are provided at the bottom end of the lower carrier 101 and arranged at equal intervals.

[0039] Operation process: When in use, solid fuel is poured into the storage bin 104a, and then the device is pushed through the handle and moved through the universal wheels at the bottom. After moving to the designated position, the two electric telescopic rods 104b are activated to drive one side of the storage bin 104a to rise. (At this time, the height of one side of the storage bin 104a is h1), and the entire upper carrier 102 starts to rotate through the rotating shaft 103. At this time, the box door will open due to centrifugal force, and the solid fuel will be discharged from the box door and the groove 105. When the storage bin 104a rotates, it will also pull the traction member upward, and the rack 202 is pulled upward through the traction member. When the rack 202 rises, it meshes with the gear 204a through the teeth, causing the gear 204a to also rotate clockwise. At the same time, several rubber blocks 204b will also rotate and continuously strike the bottom of the storage bin 104a and collide with it. Through vibration, the inside of the storage bin 104a will not adhere to solid fuel. The two electric telescopic rods 104b are used to drive the storage bin 104a to continue rising. After the storage bin 104a rotates to the apex, (at this time, the height of one side of the storage bin 104a is h2), at this time, the rack 202 also rises to the apex, and the teeth of the rack 202 will disengage from the gear 204a and no longer mesh with the gear 204a. At this time, the reaction force of the torsion spring drives the rotating rod 203 to rotate, and the rotating rod 203 drives the gear 204a and several rubber blocks 204b to start rotating counterclockwise, so that when the storage bin 104a is inclined for feeding, several rubber blocks 204b will also continuously strike, thereby preventing fixed fuel from remaining inside the storage bin 104a.

[0040] Embodiment 2

[0041] Refer to Figure 5 - Figure 7, which is the second embodiment of the present utility model. The difference between this embodiment and the first embodiment is that the cleaning member 305 includes a wire winding wheel 305a provided on the cross plate 304. There is one wire winding wheel 305a provided on each cross plate 304, a scraper 305b provided inside the storage bin 104a for cleaning the inner wall of the storage bin 104a, a fixing frame 305c provided on the scraper 305b, and a rope 305d wound and installed on the wire winding wheel 305a.

[0042] Specifically, one end of the rope 305d is fixedly installed on the counterweight 303. When the counterweight 303 moves, it will also pull the rope 305d. The other end of the rope 305d is fixedly installed on the fixing frame 305c. By pulling the fixing frame 305c with the rope 305d, the outer wall of the scraper 305b is in contact with the inner wall of the storage bin 104a, so that the solid fuel can be scraped off.

[0043] Furthermore, the rotating block 301 and the connecting member 302 are both inclined. A chute is provided on the side of the top end of the rotating block 301 away from the connecting member 302. The counterweight 303 is slidably installed in the chute. A first spring (not marked in the figure) is fixedly connected between the bottom end of the rotating block 301 close to the connecting member 302 and the lower bearing member 101. A notch is provided on the side of the scraper 305b close to the door. The diameter of the notch is the same as that of the door. By providing the notch, the solid fuel at the bottom end of the inner wall of the storage bin 104a will not be blocked by the scraper 305b during feeding.

[0044] The remaining structures are the same as those in Embodiment 1.

[0045] Operation process: Before use, first insert the connecting piece 302 into the rotating block 301. When the upper bearing piece 102 rotates for blanking, it will also pull the connecting piece 302. (At this time, the height of the upper bearing piece 102 corresponds to h1 in Embodiment 1), thereby causing the rotating block 301 to rotate and stretch the first spring. At this time, due to the downwardly inclined rotating block 301, the counterweight 303 will slide downward through the chute, and while sliding, it will pull the rope 305d. As a result, the other end of the rope 305d will pull the scraper 305b, causing the scraper 305b to rise, so as to scrape off the solid fuel adhering to the inner wall of the storage bin 104a. After the storage bin 104a rotates to the apex through the two electric telescopic rods 104b, the scraper 305b will also rise to the apex. (At this time, the height of the storage bin 104a corresponds to h2 in Embodiment 1). By pulling the end of the connecting piece 302 inserted into the rotating block 301 backward, the rotating block 301 is separated from the connecting piece 302. At this time, the rotating block 301 is pulled back to its original position by the reaction force of the first spring. At this time, the counterweight 303 will also return to its original position through the chute, and the scraper 305b will also descend and return to its original position. While descending, it will clean the inner wall of the storage bin 104a again, so that the solid fuel inside the storage bin 104a will not adhere to the inside of the storage bin 104a during blanking, preventing residual solid fuel.

[0046] Embodiment 3

[0047] Refer to Figure 8 , which is the third embodiment of the present invention. The difference between this embodiment and the second embodiment is that the pressing member 405 includes a threaded rod 405a provided on the concave frame 401, the threaded rod 405a is threadedly installed on the concave frame 401, a long plate 405b provided on the threaded rod 405a, and a turntable 405c. The long plate 405b is rotatably installed at one end of the threaded rod 405a, and an arc-shaped block 405d provided on the long plate 405b. Arc-shaped blocks 405d are provided at both ends of the long plate 405b.

[0048] Furthermore, the shape of the clamping block 403 is "C" - shaped, the diameter of the concave part of the clamping block 403 is the same as that of the combined rectangular block 404. Rectangular blocks 404 are provided at both ends of the lower bearing member 101 and the upper bearing member 102. The side of the extension block 402 close to the arc-shaped block 405d is set as an arc surface.

[0049] The remaining structures are the same as those in Embodiment 2.

[0050] Operation process: After the solid fuel feeding is completed, by rotating the turntable 405c, the threaded rod 405a rotates to push the long plate 405b, and the arc-shaped block 405d squeezes the extension block 402 to move it towards both sides, thereby pushing the latch 403 to engage with the rectangular block 404, so as to fix the lower carrier 101 and the upper carrier 102 together and prevent the upper carrier 102 from tilting during the pushing process.
