Description

Technical Field

[0001] The invention relates to the technical field of pushers, in particular to a uniform pusher for a boiler. Background Art

[0002] At present, the methods of sending garbage into the garbage incineration boiler generally adopt two types: grab bucket and pusher. The grab bucket grabs the garbage and throws it into the boiler from the top of the boiler; while the pusher dumps the garbage on the trolley platform. The trolley transports the garbage to the entrance and pushes the garbage into the furnace from the side of the boiler through the push plate, which has a pushing effect. However, since the garbage will gather and pile up after being dumped onto the trolley platform, the trolley will also cause problems of uneven combustion and combustion offset when pushing the garbage, depending on the accumulation position of the garbage, which affects the incineration effect of the boiler on the garbage. Therefore, designing a uniform boiler pusher that can prevent garbage from gathering and piling has become a technical problem that needs to be solved urgently. Summary of the invention

[0003] In order to solve the above problems, the present invention provides a boiler uniform pusher.

[0004] The technical solution of the utility model is a boiler uniform pusher, comprising a feeding platform and a push plate, a driving mechanism is provided at one end of the feeding platform, the driving mechanism is provided with a hydraulic push rod connected to the push plate, the driving mechanism is also provided with a rotating seat linked to the hydraulic push rod, the edge of the rotating seat is connected with a scraper, and the position of the scraper is aligned with the push plate.

[0005] After adopting the above structure, the garbage is put on the feeding table by the grab bucket, and the driving mechanism drives the hydraulic push rod to move, which drives the push plate to move and push the garbage along the feeding table into the incineration boiler; when the hydraulic push rod moves, the linked rotating seat rotates while the push plate moves, and the scraper shovels part of the garbage to slide to the side, avoiding the garbage from gathering and piling on the feeding table, so that the garbage can be evenly and completely burned after being pushed into the boiler.

[0006] As a further improvement of the utility model, the rotating seat is connected to a linkage rod, the linkage rod is parallel to the hydraulic push rod, the circumferential surface of the linkage rod is provided with a spiral driving groove, both sides of the driving mechanism are provided with movable holes for the linkage rod to pass through, the ends of the movable holes are provided with limit blocks inserted into the driving grooves, and the push plate is provided with a rotating shaft seat axially connected to the linkage rod.

[0007] After adopting the above structure, when the push plate moves, the rotating shaft seat drives the linkage rod to move along the axis direction of the movable hole. The limit block is inserted into the spiral driving groove to drive the linkage rod to rotate around its own axis when moving with the push plate, thereby driving the scraper to rotate.

[0008] As a further improvement of the present invention, the end of the limit block is provided with an arc surface which fits with the groove wall of the driving groove.

[0009] After adopting the above structure, an arc surface is provided at the end of the limit block to reduce the contact area with the driving groove, reduce the friction between the limit block and the driving groove, and make the linkage rod move more easily along the movable hole.

[0010] As a further improvement of the utility model, a pushing shovel that fits with the feeding platform is provided at the bottom of the pushing plate.

[0011] After adopting the above structure, a pushing shovel is arranged at the bottom of the pushing plate, so that garbage is not easily squeezed into the gap between the pushing plate and the feeding platform, thereby avoiding the pushing plate from being blocked.

[0012] As a further improvement of the utility model, the scraper is a fan-blade-shaped structure.

[0013] After adopting the above structure, the scraper has a fan-shaped structure, so that the garbage is moved obliquely to be loosened, thereby reducing the resistance to the movement of the scraper. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] like Figure 1-Figure 2 A boiler uniform pusher is shown, comprising a feed table 1 and a push plate 2, wherein a driving mechanism 3 is provided at one end of the feed table 1, wherein the driving mechanism 3 is provided with a hydraulic push rod 4 connected to the push plate 2, and the driving mechanism 3 is further provided with a rotating seat 5 linked to the hydraulic push rod 4, wherein a scraper 6 is connected to the edge of the rotating seat 5, and the position of the scraper 6 is aligned with the push plate 2.

[0018] The garbage is put onto the feeding platform 1 by the grab bucket, and the driving mechanism 3 drives the hydraulic push rod 4 to move, which drives the push plate 2 to move and push the garbage along the feeding platform 1 into the incineration boiler; when the hydraulic push rod 4 moves, the linked rotating seat 5 rotates while the push plate 2 moves, and the scraper 6 shovels part of the garbage to slide to the side, avoiding the garbage from gathering and piling on the feeding platform 1, so that the garbage can be evenly and completely burned after being pushed into the boiler.

[0019] The rotating seat 5 is connected to a linkage rod 7, and the linkage rod 7 is parallel to the hydraulic push rod 4. The circumferential surface of the linkage rod 7 is provided with a spiral driving groove 8. Both sides of the driving mechanism 3 are provided with movable holes for the linkage rod 7 to pass through. The ends of the movable holes are provided with limit blocks 9 inserted into the driving groove 8. The push plate 2 is provided with a rotating shaft seat axially connected to the linkage rod 7.

[0020] When the push plate 2 moves, the shaft seat drives the linkage rod 7 to move along the axis of the movable hole. The limit block 9 is inserted into the spiral driving groove 8 to drive the linkage rod 7 to rotate around its own axis when moving with the push plate 2, thereby driving the scraper 6 to rotate.

[0021] The end of the limit block 9 is provided with an arc surface which fits with the groove wall of the driving groove 8 .

[0022] By providing an arc surface at the end of the limit block 9, the contact area with the driving groove 8 is reduced, and the friction between the limit block 9 and the driving groove 8 is reduced, so that the linkage rod 7 can move along the movable hole more easily.

[0023] A pushing shovel 10 that fits the feeding platform 1 is provided at the bottom of the pushing plate 2 .

[0024] By arranging a pushing shovel 10 at the bottom of the pushing plate 2, it is difficult for garbage to be squeezed into the gap between the pushing plate 2 and the feeding platform 1, thereby preventing the pushing plate 2 from being blocked.

[0025] The scraper 6 is a fan-shaped structure.

[0026] The scraper 6 is fan-shaped, so that the garbage is moved obliquely to loosen, and the resistance to the movement of the scraper 6 is reduced.
