[0028] The present invention will be described in detail below in conjunction with the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional changes made by a person skilled in the art based on these embodiments are all within the scope of protection of the present invention.

[0029] Embodiment 1

[0030] like Figure 1-3 As shown, this embodiment proposes a waste treatment device for highway bridge construction, which includes:

[0031] The box body 1 is provided with a feed port 3, and an upper hopper 4 is connected above the feed port 3. The upper hopper 4 is located on the left side of the box body 1, and a support rod is connected between the bottom of the upper hopper 4 and the box body 1 to increase the stability of the upper hopper 4.

[0032] There is a conveyor belt assembly 5 for conveying waste in the box body 1. The conveyor belt assembly 5 is a prior art and will not be described in detail here. The conveyor belt assembly 5 is located at the bottom of the feed port 3, so as to catch the waste falling from the upper feed port 3; the right end of the conveyor belt assembly 5 is close to the right side of the inner wall of the box body 1, and a discharge port 6 is left between the left end of the conveyor belt assembly 5 and the left inner wall of the box body 1, and a crushing assembly 7 for crushing waste is arranged below the discharge port 6, and a material guide slope 10 is arranged below the crushing assembly 7, and a waste pit 11 is left between the right side of the material guide slope 10 and the inside of the box body 1, and a discharge port 12 is opened on the right side of the waste pit 11.

[0033] When the crushing component 7 crushes the waste from highway bridge construction, a large amount of dust will be generated. In the conventional structure, the waste is usually directly crushed by the crushing component through the feed port 3, and the dust generated is easy to be directly blown upward, affecting the surrounding environment, and has a certain impact on the physical and mental health of the operator in the long run; in this design, a stepped channel is formed between the crushing component 7 and the discharge port 6 through the conveyor belt component 5, and the dust generated during crushing will not be directly blown upward, making it difficult for the crushed dust to be blown upward from the feed port 3 through the channel, effectively avoiding the problem of dust blowing during the crushing process.

[0034] Furthermore, slide rails 13 are symmetrically arranged at both ends of the discharge port 12, and a sealing plate 14 for sealing the discharge port 12 is slidably connected in the slide rails 13. During the crushing process, the discharge port 12 at the bottom is sealed by the sealing plate 14 to prevent excessive dust from escaping from the two discharge ports after crushing.

[0035] In this embodiment, in order to maximize the cost savings of the crushing component 7, the following structure is designed: the crushing component 7 includes two transmission shafts 71 rotatably arranged in the box body 1, and the two transmission shafts 71 are provided with crushing rollers 72 for crushing coal. The two transmission shafts 71 penetrate the box body 1 and extend to the outside of the box body 1. Two meshing gears 73 are respectively provided on the outside of the two transmission shafts 71, and the two gears 73 are located outside the crushing box. One of the transmission shafts 71 is connected to a drive motor 74; it also includes a protective box 75 connected to the outside of the crushing box for covering the drive motor 74 and the gear 73; in this design, a drive motor 74 is used to drive two sets of crushing rollers 72 for crushing without affecting its original function, thereby maximizing cost savings.

[0036] The waste is transported to the discharge port 6 through the conveyor belt assembly 5, and falls downward from the discharge port 6 to be crushed by the crushing assembly 7. In order to prevent the waste from being not completely crushed and splashing outward during the crushing process of the crushing assembly 7, two groups of guide plates 15 are further provided. The two guide plates 15 are located between the discharge port 6 and the crushing assembly 7, and the two groups of guide plates 15 are fixed to the inner wall of the box body 1 in an inverted eight-shaped shape; the guide plates 15 in an inverted eight-shaped shape are used to further gather the waste in the discharge port 6 so that it can directly fall on the crushing assembly 7 to be crushed, thereby preventing the waste from falling from the side into the waste pit 11 below without being crushed.

[0037] When the waste is crushed and slides down through the guide slope 10 into the waste pit 11, in order to facilitate the removal of the waste, a pushing assembly 8 for pushing the waste in the waste pit 11 is arranged at the bottom of the guide slope 10, and the pushing assembly 8 includes an electric push rod 81, and the output end of the electric push rod 81 is connected to a push plate 82. In the initial state, the push plate 82 forms a vertical plane with the right side surface of the guide slope 10. When the garbage in the waste pit 11 accumulates to a certain extent, the sealing plate 14 is opened, and the waste will be pushed to the discharge port 12 by the electric push rod 81 and the push plate 82. Furthermore, in order to prevent the waste just crushed by the crushing assembly 7 from falling on the left side of the push plate 82 and affecting the operation of the electric push rod 81 when the push plate 82 pushes the waste to the discharge port 12, a receiving plate 83 is connected to the top of the push plate 82, and the receiving plate 83 is located on the left side of the push plate 82; the newly crushed waste is blocked by the receiving plate 83 so that the newly crushed waste falls to the top of the receiving plate 83, and when the electric push rod 81 retracts, the guide slope 10 scrapes the waste residue above the material plate 83 and scrapes the waste residue into the waste pit 11, which can effectively prevent the waste residue from falling between the push plate 82 and the electric push rod 81 to accumulate and affect the normal operation of the push rod.

[0038] Furthermore, a controller is also provided in the box body 1, and the controller is electrically connected to the drive unit, the drive motor 74 and the electric push rod 81 in the conveyor belt assembly 5. A control panel 2 is also provided on the outer wall of the box body 1, and the control template is electrically connected to the controller. The operator controls the operation of each drive unit through the control panel 2.

[0039] Working principle of this device:

[0040] The waste materials for highway bridge construction are introduced into the hopper in advance, and the waste materials fall from the feed port 3 onto the conveyor belt assembly 5, and are transported to the discharge port 6 by the conveyor belt assembly 5. The waste materials fall from the discharge port 6 onto the crushing assembly 7 and are crushed. In the process of the waste materials falling, the waste materials are prevented from splashing by the guide plate 15 and are controlled to gather between the two crushing rollers 72;

[0041] The waste is crushed by the crushing roller 72 and falls downward. The waste falls on the guide slope 10 and slides into the waste pit 11. When the crushed waste gathers to a certain extent, the sealing plate 14 is opened and the electric push rod 81 is started. The electric push rod 81 controls the sealing plate 14 to push the waste in the waste pit 11 out of the discharge port 12 for further processing.

[0042] During the crushing process, the sealing plate 14 is in a closed state, which can prevent dust from being blown out during the crushing process. At the current stage, water spraying is mostly used to reduce dust during the crushing process. It is directly applied to waste treatment devices. Although it can play a role in dust reduction, it increases the weight of the waste after crushing to a certain extent, affecting its subsequent transportation and treatment. The device in this scheme forms a stepped channel between the conveyor belt assembly 5 and the crushing assembly 7, which greatly avoids the situation of dust being blown out; at the same time, the sealing plate 14 is also used at the discharge port 12 to prevent dust from being blown out, and it is only opened in the process of removing the waste, which can effectively avoid the problem of dust being blown out during the crushing process.

[0043] Embodiment 2

[0044] like Figure 2 As shown, this embodiment proposes a waste treatment device for highway bridge construction, and the other structures are the same as those of the first embodiment. The only difference is that an extrusion assembly 9 for compressing the crushed waste in the waste pit 11 is arranged on the box body 1, and the extrusion assembly 9 includes a limit shell 91 fixed in the box body 1, and the limit shell 91 is located on the right side of the crushing assembly 7, and also includes a worm 92, one end of the worm 92 successively penetrates the box body 1 and the limit shell 91 and then rotates in the limit shell 91. Specifically, the limit shell 91 and the box body 1 can use bearings as connecting parts where they are connected to the worm 92, so that the worm 92 successively penetrates the box body 1 and the limit shell 91 without affecting the rotation of the worm 92. Shell 91; a rotatable worm wheel 93 is also provided in the limiting shell 91, and support pads are provided at the upper and lower ends of the worm 92. The support pads support the worm 92 in the limiting shell 91 without affecting the normal operation of the worm 92. The inner wall of the worm wheel 93 has a threaded section, and the inner wall of the worm wheel 93 is threadedly connected with a screw 94. A nut 95 is fixedly connected to the limiting shell 91, and the nut 95 is threadedly connected to the screw 94. Both ends of the screw 94 freely pass through the limiting shell 91 and the nut 95. The bottom end of the screw 94 is fixedly connected to a pressure plate 96, and the pressure plate 96 is located above the waste pit 11.

[0045] The worm gear 93 is driven to rotate by rotating the worm 92. When the worm gear 93 rotates, it is threadedly connected with the screw rod 94 inside it to drive the screw rod 94 to rotate. When the screw rod 94 rotates, it is threadedly connected with the nut 95 above the limit shell 91, so that the lifting of the screw rod 94 is realized. When the screw rod 94 descends, it drives the pressure plate 96 to squeeze the crushed waste in the waste pit 11, further compressing it, and taking it out from the discharge port 12 after compression, which is convenient for subsequent stacking or transportation.

[0046] Furthermore, the other end of the worm 92 is connected to a turntable 97, which is located outside the box 1, and the operator can rotate the worm 92 conveniently through the turntable 97. A limit plate 98 is fixedly connected to the top of the screw 94, and the limit plate 98 prevents the screw 94 from excessively falling and disengaging from the worm wheel 93.

[0047] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
