Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0027] In the embodiments, a building waste treatment method is given, and the present application comprises a bucket 1 and the following steps: Figs. 1-2

[0028] S1: modifying the bucket, modifying the ordinary bucket into the bucket 1, the bucket 1 is composed of digging teeth 101, reinforcing plates 102 and vertical buckets 103, the number of the digging teeth 101 is multiple, and each is fixedly connected with the front face of the vertical bucket 103, the reinforcing plate 102 is fixedly connected between each two adjacent digging teeth 101, each two adjacent digging teeth 101 are arranged in a hollow manner, the front face of the vertical bucket 103 is arranged in a bucket shape, and the vertical bucket 103 is drivably connected with the excavator;

[0029] S2: installing the bucket, driving the bucket 1 to be drivably connected with the excavator, and testing the flexibility of the bucket 1 through the hydraulic transmission system of the excavator, and then performing the operation after the turning limit requirement of the bucket 1 is met;

[0030] S3: selecting the area, driving the excavator, and selecting the area with scattered building waste piles or the area with a bagging rate lower than 20% to sort the waste;

[0031] S4: screening the waste, using the bucket 1 of the excavator to shake and sort the waste, and separating the large concrete and steel bars from the small building waste such as sandstone;

[0032] S5: separating the waste, piling up the large concrete and steel bars, manually removing the steel bars, piling up the large concrete removed into the loader and transporting it to the crushing station for crushing, and using the loader to load the small building waste such as sandstone into the loader and transporting it to the landfill site for landfill.

[0033] ​The digging bucket 1 is made of pure steel welding, the number of digging teeth 101 is not less than 5, and the spacing between adjacent two digging teeth 101 is not less than 30CM, and the vertical bucket 103 accounts for 30% of the total volume of the digging bucket 103.

[0034] The spacing between adjacent two digging teeth 101 is not less than 30CM, which is convenient for leaking out small construction waste, and separating large and solid concrete and gravel, sand and the like.

[0035] The turning limit angle of the digging bucket 1 is 180 degrees, and the excavator is a DX130 medium-sized excavator.

[0036] The 130 excavator is used, which has larger horsepower, and is convenient for pushing larger concrete construction waste.

[0037] When sorting the garbage, small construction waste such as sand and gravel leaks out through the gap between the digging teeth 101 to the ground, and larger concrete and part of the reinforcing steel is transported by the digging bucket to the surrounding area for construction waste classification.

[0038] The large and solid concrete construction waste is processed into standard coarse gravel, fine gravel, coarse sand, fine sand, and other recycled materials such as silt, and is used for secondary utilization. The steel bars and other metal products can also be recycled after manual recovery.

[0039] The crushing and secondary utilization of large and solid concrete construction waste can reduce material loss and improve the environmental protection effect of construction waste treatment.

[0040] Working principle:

[0041] The modified digging bucket 1 is assembled with the 130 excavator, and the digging bucket 1 is used through the 130 excavator to collect small piles of construction waste to form a larger construction waste cluster. In the process of collection, large and solid concrete construction waste can be intercepted in the digging bucket 1 by the vertical bucket 103, and small construction waste such as sand and gravel can be dropped through the gap between adjacent two digging teeth 101, so as to separate large construction waste from small construction waste such as sand and gravel. At the same time, small piles of construction waste are concentrated and collected, which is convenient for manual screening and reduces the use of manpower. In the screening process, longer reinforcing steel can be directly intercepted by the digging teeth 101, which is convenient for manual separation of longer reinforcing steel and construction waste, reduces the time of manual searching and screening in each construction waste pile, and thus improves the screening efficiency.
