Abstract
Description
Technical Field
[0001] This utility model relates to processing equipment, and more particularly to an intelligent crushing equipment for construction waste. Background Technology
[0002] During the construction process, a large amount of construction waste and garbage is often generated, such as metal scrap, metal-contaminated sand and soil, and waste wood. Most of the construction waste and garbage are arbitrarily landfilled and piled up by construction units without any treatment, which not only affects the environment, but also wastes renewable energy.
[0003] For larger construction waste, such as concrete blocks and bricks, it is first crushed to reduce its size. Existing construction waste processing equipment lacks buffering measures. After being crushed, the construction waste falls directly vertically into the screen, which can easily damage the screen. The equipment structure and durability are also low. Utility Model Content

A notch is opened at the left end of the upper baffle. The shell is placed directly below the base. A rectangular hole is opened on the shell corresponding to the position of the through hole at the bottom of the crusher. Two connecting rods are symmetrically arranged on the left side of the rectangular hole. A lower baffle is located between the two connecting rods. The right end of the lower baffle is placed in the notch but is not completely embedded. The first screen and the second screen are arranged vertically inside the shell. An eccentric vibration mechanism is located on the front side of the shell. A spring support is located on the outside of the shell. A discharge hopper is located on the right side of the shell.

Detailed Implementation
[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, a further detailed description of this utility model will be provided below in conjunction with the accompanying drawings. It is hereby declared that any use of terms such as "up," "down," "left," "right," "front," "back," "inner," and "outer" in this document is based solely on the accompanying drawings and is not intended to specifically limit the scope of this utility model.
[0019] A smart crushing device for construction waste, such as Figures 1-5As shown, the device includes a base 1, a crusher 2, a housing 4, an upper baffle 5, a lower baffle 6, a connecting rod 7, a first screen 10, a second screen 11, a discharge hopper 12, an eccentric vibration mechanism 13, and a spring support 14. The crusher 2 is mounted on the top of the base 1. A through hole is opened at the bottom of the crusher 2. The upper baffle 5 is hinged to the right side of the through hole. A notch is opened at the left end of the upper baffle 5. The housing 4 is placed directly below the base 1. A rectangular hole is opened on the housing 4, corresponding to the position of the through hole at the bottom of the crusher 2. The rectangular holes are symmetrical on the left side. The housing has two connecting rods 7, with a lower baffle 6 between them. The right end of the lower baffle 6 is placed in the cut, but not fully embedded, so that the lower baffle 6 can move with the vibration of the housing 4. Inside the housing 4, there is a first screen 10 and a second screen 11 arranged vertically. The screen openings of the first screen 10 are larger than those of the second screen 11. An eccentric vibration mechanism 13 is provided on the front side of the housing 4. The eccentric vibration mechanism 13 includes a motor and an eccentric block. The motor is located on the front side of the housing 4, and the eccentric block is connected to the conveyor shaft of the motor. The core block is used to drive the first screen 10 and the second screen 11 to vibrate. There are two eccentric vibration mechanisms 13. The outer shell 4 is provided with a spring support 14. The spring support 14 includes a compression spring and a support foot. The outer shell 4 is provided with a compression spring, and the bottom of the compression spring is provided with a support foot. The right side of the outer shell 4 is provided with a discharge hopper 12. There are three discharge hoppers 12, which are located on the first screen 10, the second screen 11 and the bottom right side of the outer shell 4 respectively. The outlet of each discharge hopper 12 points to a different direction to ensure that construction waste of different sizes can be properly processed. At the same time, two motors are started to make the two eccentric blocks rotate in different directions. The centrifugal force generated by the two eccentric blocks is superimposed in the horizontal and vertical directions. The centrifugal force is transmitted to the spring support 14 through the outer shell 4. The compression spring connected to the support foot can be periodically compressed and restored with the vibration of the outer shell 4, playing a dynamic support role. The centrifugal force causes the outer shell 4 to vibrate in an elliptical trajectory. The construction waste is not only thrown up on the screen surface, but also moves along the screen surface.
[0020] like Figure 4 As shown, it also includes a servo motor 9 and a spiral shaft 8. The servo motor 9 is located on the front side of the housing 4. The spiral shaft 8 is connected to the output shaft of the servo motor 9. The spiral shaft 8 passes through the housing 4 and is located directly below the lower baffle 6. The spiral shaft 8 consists of two spiral rods in opposite directions. The spiral shaft 8 can push the crushed construction waste to both sides to prevent it from accumulating or forming a blockage below the lower baffle 6.
[0021] like Figure 3 As shown, it also includes a dust cover 3. The top of the outer shell 4 is provided with a dust cover 3. The dust cover 3 is located between the rectangular hole and the through hole. The dust cover 3 can prevent dust or particles from leaking out and protect the health and safety of workers. The dust cover 3 is designed as a corrugated tube. The corrugated tube structure gives the dust cover 3 flexibility and extensibility, so that the dust cover 3 can deform with the vibration of the outer shell 4 without being easily damaged.
[0022] Construction waste is fed into the crusher 2 for crushing. The crushed construction waste first falls onto the inclined surface formed by the upper baffle 5 and the lower baffle 6 and rolls down to the first screen 10. Construction waste smaller than the screen holes of the first screen 10 will pass through the screen holes and fall to the second screen 11 under the action of vibration. Construction waste smaller than the upper screen holes of the second screen 11 will pass through the second screen 11 under the action of vibration and fall to the bottom of the outer shell 4. Finally, the three types of construction waste that are divided into different sizes move to their respective discharge hoppers 12 under the action of vibration and are discharged from the outer shell 4 along the discharge hoppers 12 for separate collection.
[0023] Specifically, the equipment structure and durability indicators:
[0024] Screen lifespan: The design of the upper and lower baffles in this utility model protects the screen from direct impact from construction waste, extending the screen's lifespan to ≥2000 hours.
[0025] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
