Description

Technical Field

[0001] This utility model relates to the field of waste screening technology, specifically a waste screening device with automatic cleaning function. Background Technology

[0002] With the growth of the urban population and the improvement of residents' living standards, the amount of urban domestic waste is constantly increasing, including a large amount of large-sized waste. If this large-sized waste is directly sent to the waste treatment facility without pretreatment, it may damage the equipment. Therefore, waste screening is necessary. However, because the shape and size of the waste vary, it will cause a lot of inconvenience to the sanitation workers when collecting and screening, which will greatly affect the efficiency of the work.

[0003] To overcome the aforementioned shortcomings, prior art 1 (Chinese patent application number 201821783162.7, application date 2019.07.09) discloses a screening device for household waste recycling, comprising a crushing box with a feed inlet at the top and an inner cavity. A right fixed plate is located near the top of the right side of the crushing box, and a forward-rotating motor is fixedly connected to the top of the right fixed plate. A left fixed plate is fixedly connected near the middle of the left side of the crushing box, and a reverse-rotating motor is fixedly connected to the top of the left fixed plate. A first bearing is fixedly connected near the top of the left side of the inner cavity of the crushing box. This screening device for household waste recycling, through the coordinated use of a forward-rotating motor, a reverse-rotating motor, a first transmission rod, a second transmission rod, blades, a vibrator, and a screen, enables it to crush and screen waste. This solves the problem that the varying shapes and sizes of waste cause significant inconvenience to sanitation workers during waste sorting, greatly impacting work efficiency.

[0004] While existing technologies can solve the problem of the inconvenience caused to sanitation workers during recycling and screening due to the different shapes and sizes of garbage, breaking up garbage may damage some items that could originally be recycled whole, thereby reducing the recycling value of these items. Furthermore, broken garbage requires more precise screening or more complex recycling processes, which may further increase processing costs and time.

[0005] To address the aforementioned issues, there is an urgent need for innovative designs based on existing waste sorting devices. Therefore, we proposed a waste sorting device with automatic cleaning function that can effectively solve these problems. Utility Model Content

[0008] It also includes: shock-absorbing springs, four of which are fixedly installed symmetrically along the axis at the bottom of the main body, and the ends of the shock-absorbing springs away from the main body are respectively fixedly installed on the upper end of the support body. The upper end of the support body is provided with a feed inlet, and the position of the feed inlet is opposite to the position of the discharge port. The lower end of the support body is fixedly installed with a loading groove, and the position of the loading groove is opposite to the position of the feed inlet.

[0009] Preferably, the screening mechanism includes a transmission assembly and a screening assembly. The transmission assembly includes an eccentric rod, an eccentric wheel, and a transmission disc. Two eccentric rods are rotatably connected through the left and right sides of the main body, and the positions of the eccentric rods on the left and right sides correspond to each other. The eccentric rods at the lower ends of the left and right sides of the main body are fixedly connected to the output end of the screening motor. A first transmission rod is rotatably installed on the left and right sides of the main body. The two first transmission rods are respectively connected to the two eccentric rods on the same side through a bevel gear set. An eccentric wheel is fixedly connected to the end of the eccentric rods on the left and right sides of the main body away from the first transmission rod. A transmission disc is rotatably installed on the side of the four eccentric wheels. One side of each of the four transmission discs is fixedly installed on the screening assembly.

[0010] Preferably, the screening component includes a guard plate, a baffle, and a screen. Multiple baffles are fixedly installed on the upper end of the screen, and guard plates are fixedly installed on the left and right ends of the screen. Two transmission discs are fixedly installed on the side of the two guard plates away from the screen.

[0011] Preferably, the cleaning assembly includes a second transmission rod, a threaded rod, a cleaning linkage rod, a slide rod, and a fixed base. The second transmission rod rotatably extends through the left side of the main body, with its left end connected to the output end of the cleaning motor. The right end of the second transmission rod is connected to the lower end of the threaded rod via a bevel gear set. The upper end of the threaded rod is rotatably connected to the interior of the rear side of the main body, and the threaded rod is parallel to the screen. The fixed base is fixedly installed inside the right side of the main body, and its position is opposite to that of the second transmission rod. The lower end of the slide rod is rotatably connected to the fixed base, and its upper end is rotatably installed inside the interior of the upper rear side of the main body. The slide rod is parallel to both the screen and the threaded rod.

[0014] Compared with the prior art, the beneficial effects of this utility model are: this waste screening device with automatic cleaning function can not only effectively screen waste of different sizes, but also retain some items that can be recycled in whole. At the same time, the cleaning component can remove the waste adhering to the screen at all times, preventing the screen holes from clogging and maintaining screening efficiency. The specific details are as follows:

[0015] (1) A screen is provided. The screening motor drives the eccentric rod to rotate, so that the eccentric wheels on the left and right sides of the main body rotate at the same time, thereby driving the screen to rotate around the four eccentric wheels as the axis. Because the screen is fixedly installed with multiple baffles, when screening garbage, larger garbage will move upward along the screen until it reaches the top of the screen and is screened out through the combined action of the screen rotation and the baffles. Smaller garbage will be screened out through the mesh holes on the screen under the movement of the screen. The overall screening process is simple and convenient. It can not only effectively screen garbage of different sizes, but also effectively retain some items that can be recycled in whole.

[0016] (2) A cleaning linkage rod is provided. The cleaning motor drives the second transmission rod to drive the threaded rod to rotate, thereby causing the cleaning linkage rod on the threaded rod to move. During the movement, the cleaning brush installed on the cleaning linkage rod cleans the adhering material at the lower end of the screen. At the same time, multiple knocking blocks installed on the cleaning linkage rod will knock the screen. When the screen is knocked, it will vibrate, thereby removing the garbage that the cleaning brush on the screen has not cleaned. This device can quickly remove the garbage adhering to the screen when needed, prevent the screen holes from being blocked, and maintain screening efficiency. Attached Figure Description

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.

[0026] Example 1:

[0027] In this embodiment, a screening mechanism is used to improve overall screening efficiency. Its purpose is to separate waste of different sizes while retaining items that could originally be recycled whole, such as... Figures 1-7 The technical solution shown includes a main body 1, a screening motor 2, a cleaning motor 3, and a discharge port 14. The cleaning motor 3 is fixedly installed on the left side of the main body 1, and a cleaning component is fixedly connected to the output end of the cleaning motor 3. Screening motors 2 are symmetrically fixedly installed on the left and right sides of the main body 1, and a screening mechanism is fixedly connected to the output end of the screening motors 2. A discharge port 14 is provided at the lower end of the main body 1. Four shock-absorbing springs 15 are symmetrically fixedly installed at the bottom of the main body 1 along an axis. The ends of the shock-absorbing springs 15 furthest from the main body 1 are respectively fixedly installed on the upper end of a support body 16.

A loading trough 17 is fixedly installed at the lower end of the support body 16, and the loading trough 17 is opposite to the feed inlet. The screening mechanism includes a transmission assembly and a screening assembly. The transmission assembly includes an eccentric rod 4, an eccentric wheel 18, and a transmission disc 6. Two eccentric rods 4 are rotatably connected through the left and right sides of the main body 1, and the positions of the eccentric rods 4 on the left and right sides correspond to each other. The eccentric rods 4 at the lower ends of the left and right sides of the main body 1 are fixedly connected to the output end of the screening motor 2. First transmission rods 5 are rotatably installed on the left and right sides of the main body 1, and the two first transmission rods 5 are respectively connected to the output end of the screening motor 2 on the same side. The two eccentric rods 4 are connected by a bevel gear set. Eccentric wheels 18 are fixedly connected to the ends of the eccentric rods 4 on both sides of the main body 1, away from the first transmission rod 5. Transmission discs 6 are rotatably mounted on the sides of the four eccentric wheels 18. One side of each of the four transmission discs 6 is fixedly mounted on a screening assembly. The screening assembly includes a guard plate 9, a baffle 8, and a screen 7. Multiple baffles 8 are fixedly mounted on the upper end of the screen 7. Guard plates 9 are fixedly mounted on both the left and right ends of the screen 7. Two transmission discs 6 are fixedly mounted on the sides of the two guard plates 9 away from the screen 7. The screening motor 2 drives the eccentric rods 4 to rotate, causing the main body 1... The eccentric wheels 18 on both sides rotate simultaneously, thereby driving the screen 7 to rotate around the four eccentric wheels 18 as the axis. Because the screen 7 is fixedly installed with multiple baffles 8, when screening garbage, larger garbage volumes move upward along the screen 7 through the combined action of the rotation of the screen 7 and the baffles 8 until they reach the top of the screen 7 and are screened out. Smaller garbage will be screened out through the mesh holes on the screen 7 under the movement of the screen 7. The overall screening process is simple and convenient. It can not only effectively screen garbage of different sizes, but also retain some items that can be recycled in whole.

[0028] Example 2:

[0029] In this embodiment, a cleaning component is used to extend the life of the screen 7. Its purpose is to remove material adhering to the screen 7 and prevent clogging of the screen holes. Specifically, as follows... Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the cleaning assembly includes a second transmission rod 10, a threaded rod 11, a cleaning linkage rod 20, a slide rod 13, and a fixed base 12. The second transmission rod 10 rotatably passes through the left side of the main body 1. The left end of the second transmission rod 10 is connected to the output end of the cleaning motor 3. The right end of the second transmission rod 10 is connected to the lower end of the threaded rod 11 via a bevel gear set. The upper end of the threaded rod 11 is rotatably connected to the rear interior of the main body 1, and the threaded rod 11 is parallel to the screen 7.

The left end of the cleaning linkage rod 20 is threadedly connected to the threaded rod 11, and the right end of the cleaning linkage rod 20 is slidably connected to the slide rod 13. A cleaning brush 21 and a working rod 23 are horizontally fixedly mounted on the cleaning linkage rod 20. The cleaning brush 21 and the working rod 23 are parallel to each other. When the cleaning brush 21 is working, it is parallel to the screen 7 and the threaded rod 11 respectively. The screen 7 is tightly fitted, and multiple striking blocks 22 are evenly installed on another working rod 23. The striking blocks 22 and the working rod 23 are connected by spiral springs 19. The upper ends of the striking blocks 22 are perpendicular to the screen 7. When working, the upper end of the striking block 22 is higher than the distance between the striking block 22 and the screen 7. The striking blocks 22 will reciprocate when striking the screen 7. The cleaning motor 3 drives the second transmission rod 10 to drive the threaded rod 11 to rotate, thereby causing the cleaning linkage rod 20 on the threaded rod 11 to move forward. During the movement, the cleaning brush 21 installed on the cleaning linkage 20 cleans the adhering material on the lower end of the screen 7. At the same time, because the striking block 22 and the working rod 23 are connected by the spiral spring 19, the striking block 22 installed on the working rod 23 will continuously strike the screen 7 during the movement. The striking will cause the screen 7 to vibrate, thereby cleaning the residual adhering material on the screen 7 a second time. This device can quickly remove the garbage adhering to the screen 7 when needed, prevent the screen holes from clogging, and maintain screening efficiency.
