Description

Technical Field

[0001] This utility model relates to the field of waste screening, specifically an iron removal device for waste screening. Background Technology

[0002] Waste sorting generally refers to a series of activities involving the sorting, collection, transportation, and treatment of waste according to certain regulations or standards, thereby transforming it into public resources.

[0003] In the prior art, when recycling waste, it is generally necessary to screen the iron objects in the waste for recycling and reuse. However, in the prior art, when screening iron objects in waste, the waste often piles up together, and some iron objects pile up at the bottom, making it difficult to be attracted by the magnet above. This results in a lack of efficiency in removing iron. Based on this, the present invention proposes an iron removal device for waste screening. Utility Model Content

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] By setting up a transmission mechanism, when it is necessary to screen the garbage, the drive motor is started to drive the garbage conveyor belt to transport the garbage on the upper surface. At the same time, the power of the garbage conveyor belt is transmitted to the movable rod, which moves back and forth along the inclined direction of the guide groove through the guide rod to sort the garbage on the upper surface of the garbage conveyor belt and expose the iron objects at the bottom, making it easier for the magnet to pick them up.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-3 In this embodiment of the utility model, an iron removal device for garbage screening includes a screening box 1 and a magnet conveyor belt 2 disposed on the upper layer of the inner cavity of the screening box 1 to pick up iron objects, and also includes a transmission mechanism 3 disposed in the inner cavity of the screening box 1 for sorting garbage.

[0024] Transmission mechanism 3 includes a transmission unit and a sorting unit;

[0025] The drive unit is used to provide power for the movement of the sorting unit;

[0026] The sorting unit is used to break up accumulated garbage and prevent localized pile-up of garbage.

[0027] The transmission unit includes a drive motor 301, a waste conveying synchronous belt 302, an intermediate synchronous pulley 303, a rotating wheel 304, a guide groove 305, and a guide rod 306;

[0028] The drive motor 301 is installed on one side of the screening box 1. The output end of the drive motor 301 is connected to an active rotating roller that extends into the inner cavity of the end of the waste conveying synchronous belt 302. The waste conveying synchronous belt 302 is tensioned on the outer wall of the active rotating roller and another passive transmission roller.

[0029] The intermediate synchronous wheel 303 is rotatably installed in the inner cavity of the screening box 1 and extends to the inner side of the garbage conveying synchronous belt 302 to mesh with the inner tooth groove of the garbage conveying synchronous belt 302. The intermediate synchronous wheel 303 is used to synchronously drive the rotating wheel 304 to rotate. The rotating wheel 304 is fixed to the end of the intermediate synchronous wheel 303. The rotating wheel 304 is used to synchronously drive the guide groove 305 opened on the outer wall to rotate circumferentially. The guide groove 305 is used to drive one end of the guide rod 306 located in the inner cavity to move axially back and forth. The guide rod 306 is fixed to the bottom end of the movable rod 307. The guide rod 306 is used to drive the movable rod 307 to move synchronously.

[0030] The organizing unit includes the movable lever 307 and the pusher lever 308;

[0031] The movable rod 307 is laterally slidably installed in the inner cavity of the screening box 1, and both ends of the movable rod 307 penetrate into the inner wall of the screening box 1. The push rod 308 is fixed to the bottom of the movable rod 307 and extends to the upper surface of the waste conveying synchronous belt 302. The laterally reciprocating push rod 308 is used to push and disperse the waste on the upper surface of the waste conveying synchronous belt 302 to avoid local accumulation of waste.

[0032] In this embodiment: by accumulating garbage on the upper surface of the garbage conveying synchronous belt 302, and then starting the drive motor 301, the active rotating roller connected to the output end of the drive motor 301 drives the garbage conveying synchronous belt 302 that is sleeved and engaged with the outer wall, so that the garbage accumulated on the upper surface of the garbage conveying synchronous belt 302 enters the interior of the screening box 1 with the transmission of the garbage conveying synchronous belt 302, and the iron objects in the garbage are picked up by the magnet conveyor belt 2 distributed in the upper layer of the inner cavity of the screening box 1.

[0033] During the transmission process of the waste conveying synchronous belt 302, the waste conveying synchronous belt 302 synchronously drives the intermediate synchronous wheel 303, which is engaged with the inner cavity, to rotate. This causes the rotating wheel 304, which is fixed at the other end of the intermediate synchronous wheel 303, to rotate synchronously. The guide groove 305, which is opened on the outer wall of the rotating wheel 304, will also move circumferentially with the rotation of the rotating wheel 304. The guide groove 305, which is connected end to end and is in a curved state, will give the bottom spherical block of the guide rod 306 a thrust, causing the guide rod 306 to move laterally and reciprocally along the curved trajectory of the guide groove 305. This synchronously drives the movable rod 307, which is fixed at the top of the guide rod 306, to move laterally and reciprocally. This drives the multiple push rods 308, which are fixed at the bottom of the movable rod 307, to move synchronously. The movable push rods 308 push and disperse the waste accumulated on the upper surface of the waste conveying synchronous belt 302, exposing the iron inside the waste, so that the magnetic conveyor belt 2 can better pick up the iron in the waste.

[0034] Please refer to this carefully. Figures 1-3The inner cavity of the waste conveying synchronous belt 302 is formed with tooth grooves that match the tooth blocks on the outer wall of the intermediate synchronous wheel 303. The tooth grooves are evenly distributed in the inner cavity of the waste conveying synchronous belt 302. The surfaces of the active rotating roller and the driven synchronous roller are formed with tooth blocks that mesh with the tooth grooves on the inner side of the waste conveying synchronous belt 302. The lateral outer walls of the push rods 308 are symmetrically inclined. There are multiple push rods 308. The multiple push rods 308 are evenly distributed at the bottom of the movable rod 307. The bottom of the guide rod 306 is spherical. The spherical block at the bottom of the guide rod 306 cooperates with the inner cavity of the guide groove 305.

[0035] In this embodiment: This structure allows the push rod 308, which is symmetrically inclined on both sides, to better disperse accumulated waste during lateral reciprocating movement via its inclined surface. The bottom of the spherical guide rod 306 allows the guide groove 305 to provide better thrust for the lateral reciprocating movement of the guide rod 306 as the rotating wheel 304 rotates. The above description is merely a preferred embodiment of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
