Description

Technical Field

[0001] The utility model relates to the field of waste incineration treatment, in particular to a hierarchical control pusher. Background Art

[0002] A pusher is a transfer device that pushes the waste that slides into the waste hopper forward to push the waste in the waste chute towards the grate. When the pusher reaches the end, due to gravity, the waste above falls into the just-vacated space, and then by the next forward movement of the pushing device, the waste is pushed onto the grate.

[0003] The utility model with the publication number CN208349309U relates to a domestic waste pusher, which discloses that a pusher platform is installed on a base, a guide rail and wear-resistant plates are arranged on the pusher platform, and the wear-resistant plates are assembled on the pusher platform in not less than one piece; the pusher trolley is arranged on the guide rail and can push the waste forward under the action of a hydraulic cylinder to realize feeding. There is a gap between the wear-resistant plates, and the opposite side surfaces of two adjacent wear-resistant plates are inclined surfaces; a diversion hole is arranged on the pusher platform, and the diversion hole is opposite to the gap left between the wear-resistant plates. The leachate collection hopper is arranged below the base and communicates with the diversion hole to collect waste leachate.

[0004] For the waste pusher in the above technical solution, traditional single-direction guide wheels are adopted under the pusher. During use, it can only guide and position the pusher back and forth. When the amount of waste from the feed port is large, the pusher will continue to move forward under the action of hydraulic pressure. When encountering the resistance of the waste, the front half of the pusher will tilt upwards, thus damaging the pusher hydraulic device, and the waste leachate will penetrate into the bottom of the pusher accordingly. Content of the Utility Model

[0005] In order to make the pusher more stable during use, the present application provides a hierarchical control pusher.

[0006] The hierarchical control pusher provided by the present application adopts the following technical solution:[[]]

[0007] A hierarchical control pusher includes a frame, a pusher plate and a driving mechanism. A first guide rail is provided on the frame. The pusher plate is slidably connected to the first guide rail in the horizontal direction. Two groups of first pulleys are rotatably connected to the pusher plate, and the two groups of first pulleys are respectively slidably connected to the upper and lower sides of the first guide rail. The driving mechanism is used to drive the sliding of the pusher plate.

[0008] By adopting the above technical solution, two groups of first pulleys are respectively slidably connected to the upper and lower sides of the first guide rail to limit the sliding of the pushing plate, reduce the possibility of the pushing plate tilting during operation, and reduce the possibility of a large friction coefficient between the pushing plate and the slide rail, and reduce the possibility of the pushing plate being stuck, thereby increasing the stability of the pushing plate operation and enabling the pushing plate to operate continuously.

[0011] Preferably, a scraping plate is arranged at one end of the pushing plate away from the frame.

[0012] By adopting the above technical solution, the possibility of landfill leachate seeping into the bottom of the pushing plate is reduced.

[0013] Preferably, the upper end to the lower end of the scraping plate is tapered.

[0014] By adopting the above technical solution, the contact area between the scraping plate and the incinerator is reduced, thereby reducing the possibility of the pushing plate being stuck, guiding the pushed garbage and reducing the possibility of the garbage being brought back by the scraping plate after being pushed out.

[0016] By adopting the above technical solution, when the first pulley slides onto the ball, the first pulley drives the ball to rotate, and the ball takes out the lubricating grease in the oil cavity onto the first pulley and the first guide rail to reduce the friction coefficient between the first pulley and the first guide rail, reduce the possibility of the pushing plate being stuck, and increase the stability of the pushing plate operation, enabling the pushing plate to operate continuously.

[0017] Preferably, the driving mechanism includes a first hydraulic cylinder and a connecting rod, a plurality of hinge blocks are arranged on the connecting rod, the plurality of hinge blocks are respectively hinged to the pushing plate, the first hydraulic cylinder is arranged on the frame, and one end of the piston rod of the first hydraulic cylinder is fixedly connected to the connecting rod.

[0018] By adopting the above technical solution, the piston movement of the piston rod of the first hydraulic cylinder drives the push plate to move back and forth to push the material. By hingedly connecting the hinge block to the push plate, the possibility of the pusher shaking up and down and damaging the first hydraulic cylinder is reduced.

[0019] Preferably, the driving member also includes a second hydraulic cylinder, a sliding rod is slidably connected to the frame in a horizontal direction, the first hydraulic cylinder is fixedly connected to the sliding rod, the second hydraulic cylinder is fixedly connected to the frame, and one end of the piston rod of the second hydraulic cylinder is fixedly connected to the sliding rod.

Through the movement of the first hydraulic cylinder and the second hydraulic cylinder, the push plate can slide in stages.

[0021] The technical effects of this utility model are mainly reflected in the following aspects:

[0022] 1.

[0023] 2. The utility model further limits the sliding of the push plate by making two sets of second pulleys slidably connected to one end of the two second guide rails close to the first guide rail, thereby reducing the possibility of the push plate shaking left and right during operation, making the push plate more stable during use;

[0024] 3. The utility model provides an oil chamber and a ball. When the first pulley slides onto the ball, the first pulley drives the ball to rotate.

Detailed implementation manners

[0030] The following is a further detailed description of the present application in combination with the attached Figures 1-4 to make the technical solution of the present application easier to understand and master.

[0031] The embodiment of the present application discloses a hierarchical control pusher.

[0032] Referring to Figures 1-4 , a hierarchical control pusher in this embodiment includes a frame 1, a pusher plate 2 and a drive mechanism 3. First guide rails 11 are fixedly connected to both sides of the frame 1 in the length direction. The pusher plate 2 is slidably connected to the first guide rails 11 in the horizontal direction. Two groups of first pulleys 21 are rotatably connected to both sides of the pusher plate 2 in the length direction. The two groups of first pulleys 21 are respectively slidably connected to the upper and lower sides of the first guide rails 11. Each group of first pulleys 21 includes a plurality of first pulleys 21, and the plurality of first pulleys 21 are evenly distributed along the length direction of the corresponding first guide rail 11. The drive mechanism 3 is used to drive the sliding of the pusher plate 2. Second guide rails 12 are fixedly connected to both sides of the frame 1 in the length direction. The two second guide rails 12 are arranged parallel to the first guide rails 11. Two groups of second pulleys 22 are rotatably connected to the pusher plate 2. The two groups of second pulleys 22 are respectively slidably connected to the opposite side surfaces of the two second guide rails 12.

[0033] Referring to Figure 3 , the two groups of first pulleys 21 are respectively slidably connected to the upper and lower sides of the first guide rail to limit the sliding of the pusher plate 2, reduce the possibility of the pusher plate 2 tilting during operation, and reduce the possibility of a large friction coefficient between the pusher plate 2 and the slide rail, and reduce the possibility of the pusher plate 2 getting stuck, so as to increase the running stability of the pusher plate 2 and enable the pusher plate 2 to run continuously. Further limit the sliding of the pusher plate 2 to reduce the possibility of the pusher plate 2 shaking left and right during operation, and make the pusher plate 2 more stable during use.

[0034] Referring to Figures 1-4, a scraping plate 23 is fixedly connected to the end face of the material pushing plate 2 away from the frame 1. The possibility of landfill leachate seeping into the bottom of the material pushing plate 2 is reduced. The upper end to the lower end of the scraping plate 23 is tapered. The contact area between the scraping plate 23 and the incinerator is reduced, thereby reducing the possibility of the material pushing plate 2 getting stuck, guiding the pushed garbage and reducing the possibility of the garbage being brought back by the scraping plate 23 after being pushed out.

[0035] Refer to Figures 1-4 , an oil cavity is formed in the first guide rail 11, and the oil cavity is filled with grease. A plurality of mating grooves 112 communicating with the oil cavity are respectively formed on the upper and lower sides of the end of the first guide rail close to the frame 1. A plurality of balls 113 are movably connected in the plurality of mating grooves 112 respectively, and the plurality of balls 113 are respectively located on the moving path of the first pulley 21. When the first pulley 21 slides onto the balls 113, the first pulley 21 drives the balls 113 to rotate, and the balls 113 carry the grease in the oil cavity onto the first pulley 21 and the first guide rail, so as to reduce the friction coefficient between the first pulley 21 and the first guide rail, reduce the possibility of the material pushing plate 2 getting stuck, and increase the running stability of the material pushing plate 2, so that the material pushing plate 2 can run continuously.

[0036] Refer to Figures 1-4 , the driving mechanism 3 includes a first hydraulic cylinder 31 and a connecting rod 32. A plurality of hinge blocks 33 are fixedly connected to the connecting rod 32. The plurality of hinge blocks 33 are respectively hinged to the material pushing plate 2 along the length direction of the material pushing plate 2. The driving member further includes a second hydraulic cylinder 35. A sliding rod 34 is slidably connected to the frame 1 in the horizontal direction. The first hydraulic cylinder 31 is fixedly connected to the sliding rod 34. One end of the piston rod of the first hydraulic cylinder 31 is fixedly connected to the connecting rod 32. The second hydraulic cylinder 35 is fixedly connected to the frame 1. One end of the piston rod of the second hydraulic cylinder 35 is fixedly connected to the sliding rod 34. Through the piston movement of the piston rod of the first hydraulic cylinder 31, the material pushing plate 2 is driven to reciprocate for pushing materials. By hinging the hinge blocks 33 to the material pushing plate 2, the possibility of the material pushing plate 2 shaking up and down and thus damaging the first hydraulic cylinder 31 is reduced. Through the piston movement of the piston rod of the second hydraulic cylinder 35, the sliding rod 34 is driven to slide, so that the first hydraulic cylinder 31 slides on the frame 1. Through the movements of the first hydraulic cylinder 31 and the second hydraulic cylinder 35, the material pushing plate 2 can slide step by step.

[0037] Of course, the above are only typical examples of the present application. In addition, the present application can also have many other specific implementation manners. Any technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present application.
