Description

Technical Field

[0001] This utility model belongs to the field of waste treatment, specifically a construction waste sorting device. Background Technology

[0002] The purpose of construction waste sorting is to achieve resource recovery, volume reduction, and separation of hazardous substances from construction waste, thereby minimizing negative environmental impacts. Sorting equipment includes fixed screens, vibrating screens, drum screens, magnetic separators, flotation machines, and optical separators. These devices are designed based on sorting principles and material characteristics to meet diverse sorting needs.

[0003] The sorting equipment mentioned above is primarily used in scenarios involving large-scale waste sorting. In reality, many times the amount of waste requiring sorting is not so large that these large machines are unnecessary. This is because the cost of using such equipment for sorting small amounts of construction waste far outweighs the value of the usable materials extracted. Utility Model Content

[0004] The technical problem to be solved: Design a device suitable for sorting small amounts of waste.

[0005] Technical Solution: This utility model provides a construction waste sorting device, including a main component and a swinging component: the main component includes a base plate, two vertical supports are symmetrically connected to the top of the base plate, and a horizontal rotating shaft is connected to the supports through bearings. A hopper is fixed between the two rotating shafts, and a screen plate is installed inside the hopper. An inner disc is installed outside the supports at the outer end of the rotating shaft. The swinging component includes an outer disc outside the inner disc, which is in the same horizontal direction as the center of the inner disc and has a larger diameter than the inner disc. The outer disc is fixed to the supports through a connecting mechanism, and a fan-shaped arc groove is opened through it near the bottom. In addition, a swinging mechanism is provided outside the supports to limit the inner disc from swinging back and forth along the path of the arc groove.

[0006] Furthermore, the swing mechanism includes a rod vertically connected to the bottom of the inner disk at a position away from the center, which extends through an arcuate groove to the outer end of the outer disk.

[0007] Furthermore, the bracket has a through-hole at the position of the corresponding bearing. The inner wall of the through-hole is fixedly connected to the outer ring of the bearing, and the inner ring is interference-fitted with the shaft and passes through.

[0008] Furthermore, a servo motor with a horizontal output shaft can be installed outside the bracket. The outer periphery of the output shaft and the rotating shaft of the servo motor are fixedly fitted with mutually meshing gears located between the inner disk and the bracket.

[0009] Furthermore, an elastic sleeve can be fitted onto the outer periphery of the insertion rod, with the inner side of the sleeve located outside the outer disk.

[0010] Furthermore, the connecting mechanism includes multiple crossbars connected to the inner side of the outer disc, the inner sides of which are fixedly connected to the outer side of the bracket.

[0011] Technical Effects: In this invention, the inner disc swings back and forth along the path of the arc-shaped groove under the action of the swing mechanism. This arc-shaped groove is fan-shaped, so for the hopper, it is equivalent to making the hopper swing back and forth. In this way, the construction waste in the hopper can be quickly screened and separated. This structure is suitable for the rapid screening of small amounts of construction waste without the need for additional large sorting equipment. Attached Figure Description

[0017] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0018] The construction waste sorting device provided in this specific embodiment, such as Figure 1 As shown, it includes a main body component and a swinging component, wherein:

[0019] The main components include a base plate 1, with two vertical supports 2 symmetrically connected to the top of the base plate 1. A horizontal rotating shaft 3 is connected to each support 2 via bearings. Specifically, mounting holes are drilled through the support 2 at the corresponding bearing positions. The inner wall of the mounting hole is fixedly connected to the outer ring of the bearing, and the inner ring is press-fitted into the rotating shaft 3. Furthermore, a hopper 4 is fixed between the two rotating shafts 3. A screen plate 5 is installed inside the hopper 4, and an inner disc 6 located outside the support 2 is installed at the outer end of the rotating shaft 3.

[0020] The swinging component includes an outer disk 7 located outside the inner disk 6, horizontally aligned with the center of the inner disk 6, and with a diameter larger than the inner disk 6. The outer disk 7 is fixed to the bracket 2 via a connecting mechanism 8, and has a fan-shaped arc-shaped groove 9 extending through it near its bottom end. For the connecting mechanism 8, as shown... Figure 3 As shown, the connecting mechanism 8 includes multiple crossbars 801 connected to the inner side of the outer disk 7, and the inner sides of these crossbars 801 are all fixedly connected to the outer side of the bracket 2. In addition, a swing mechanism 10 is also provided outside the bracket 2 to limit the back-and-forth swinging of the inner disk 6 along the path of the arc-shaped groove 9, such as... Figure 3 As shown, the swing mechanism 10 includes a rod 1001 vertically connected to the bottom of the inner disc 6 at a position away from the center. The rod 1001 passes through the arc-shaped groove 9 and extends to the outer end of the outer disc 7. Thus, the rod 1001 serves as a handle, which the user holds and manually rotates back and forth within the arc-shaped groove 9, causing the hopper 4 to swing rapidly back and forth for quick screening of construction waste. Furthermore, for ease of use, a flexible sleeve can be fitted onto the outer periphery of the rod 1001. This sleeve acts as an anti-slip device for gripping, and its inner side is located outside the outer disc 7 to avoid affecting the swing between the rod 1001 and the arc-shaped groove 9.

[0021] In addition, such as Figure 2 As shown, a servo motor 11 with its output shaft in the horizontal direction can be installed outside the bracket 2. The output shaft of the servo motor 11 and the outer periphery of the rotating shaft 3 are both fixedly fitted with meshing gears 12 located between the inner disc 6 and the bracket 2. Due to the presence of the insertion rod 1001 and the arc-shaped groove 9, this servo motor 11 and gear 12 structure can also drive the hopper 4 to swing. Furthermore, this drive is electric and does not require manual rotation by the user.

[0022] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0023] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
