Description

Technical Field

[0001] The utility model relates to a screening bucket, in particular to a soil improvement screening bucket, belonging to the technical field of excavators. Background Art

[0002] Soil remediation is a technical measure used to restore contaminated soil to its normal function. In the soil remediation industry, there are more than a dozen commonly used techniques, which can be roughly divided into three methods: physical, chemical, and biological. When chemically oxidizing and remediating contaminated soil, a corresponding screening bucket is often used. Screening buckets can efficiently screen the soil to meet the needs of soil improvement. Screening can remove large impurities and stones in the soil, improving soil purity and uniformity. At the same time, crushing can make soil particles smaller, which is beneficial to improving soil fertility and the growth of plant roots.

[0003] However, the soil particles excavated by the screening bucket are uneven, and there are large impurities and stones in the soil, which leads to poor screening effect of the screen on the soil and easy clogging of the screen holes. As a result, the screen needs to be frequently replaced and repaired when the screening bucket is used, resulting in low screening efficiency, which in turn affects the progress of soil improvement and remediation operations.

[0024] As a technical optimization solution of the present invention, a groove 5 is provided on the screening bucket main body 1, and the screen 3 is slidably connected in the groove 5; when installing the screen 3, the screen 3 is aligned with the groove 5 at the top of the screening bucket main body 1, and the screen 3 is pushed downward to slide in the groove 5, and the screen 3 is continuously pushed so that the bottom end of the screen 3 is engaged with the groove 5 at the bottom end of the screening bucket main body 1, thereby preliminarily fixing the screen 3.

[0025] As a technical optimization solution of the present invention, the limiting structure 4 includes a limiting groove 401, a limiting groove 401 is provided on the screen 3, a limiting block 402 is engaged in the limiting groove 401, and the limiting block 402 is slidably connected to the screening bucket main body 1. The limiting block 402 is an "L"-shaped structure, and a tension spring 403 is fixedly connected between the limiting block 402 and the screening bucket main body 1. A knob 404 is abutted on the limiting block 402, and the end of the knob 404 is threadedly connected to the screening bucket main body 1; during the sliding process of the screen 3, it conflicts with the limiting block 402 and slides toward the outside of the screening bucket main body 1, and the limiting block 402 drives the tension spring 403 to extend, and continuously Push the screen 3 so that the bottom end of the screen 3 engages with the groove 5 at the bottom end of the screening bucket main body 1. At this time, the limit groove 401 on the screen 3 is aligned with the limit block 402, and the tension spring 403 is reset. The tension spring 403 drives the limit block 402 to engage with the limit groove 401, thereby fixing the screen 3. Then, the knob 404 passes through the limit block 402, so that the end of the knob 404 is threadedly connected to the screening bucket main body 1, and the knob 404 is continuously rotated until the knob 404 is pressed against the limit block 402, thereby further fixing the limit block 402, thereby increasing the stability of the installation of the screen 3. The screen 3 is detachable, which is convenient for replacing the screen 3 with different sizes of mesh or disassembly and maintenance.

[0026] As a technical optimization solution of the present invention, a shovel plate 6 is installed at one end of the screening bucket body 1 facing away from the screen 3, and the shovel plate 6 is provided with an inclined structure; since the shovel plate 6 has a sharp inclined structure, it can better cut into the soil, making it easier for the screening bucket body 1 to dig the soil, and the shovel plate 6 is installed by bolts, which is convenient for disassembly and replacement.

[0028] When the utility model is in use, the connecting piece 9 is first installed on the shovel frame of the excavator, and the screening bucket body 1 is driven by the excavator to dig soil or sand. When the screening bucket body 1 contacts the soil, the shovel plate 6 has a sharp inclined surface structure, which can better cut into the soil, making it easier for the screening bucket body 1 to dig the soil. The shovel plate 6 is installed by bolts and is easy to disassemble and replace. When the soil enters the screening bucket body 1, the motor 201 is started, and the motor 201 drives the first rotating shaft 202 to rotate. The first rotating shaft 202 drives the driving gear 203 to rotate. The driving gear 203 is meshed with the driven gear 204, causing the driven gear 204 to rotate. The driven gear 204 is driven The rotation simultaneously drives the second rotating shaft 205 to rotate, and the first rotating shaft 202 and the second rotating shaft 205 drive the two crushing rollers 206 to rotate, so that the two crushing rollers 206 are in a working state, and the shovel frame of the excavator drives the screening bucket body 1 toward one end of the shovel plate 6 through the connecting piece 9, so that the soil excavated by the screening bucket body 1 moves toward the two crushing rollers 206, and then the two crushing rollers 206 cooperate with each other to crush the soil, so that the large pieces of soil in the screening bucket body 1 are crushed, and then it is convenient to screen the soil through the screen 3, thereby improving the working efficiency of the screening bucket body 1; the crushed soil moves toward the direction of the screen 3, and then passes through the sieve holes of the screen 3. When the screen 3 is installed, the screen 3 is aligned with the groove 5 at the top of the screening bucket main body 1, and the screen 3 is pushed downward to make the screen 3 slide in the groove 5. During the sliding process, the screen 3 hits the limit block 402 and slides toward the outside of the screening bucket main body 1. The limit block 402 drives the tension spring 403 to extend, and continuously pushes the screen 3 so that the bottom end of the screen 3 is engaged with the groove 5 at the bottom end of the screening bucket main body 1. At this time, the limit groove 401 on the screen 3 is aligned with the limit block 402, the tension spring 403 is reset, and the tension spring 403 drives the limit block 402 to engage with the limit groove 401, thereby making the screen The mesh 3 is fixed, and then the knob 404 is passed through the limit block 402, so that the end of the knob 404 is threadedly connected to the screening bucket body 1, and the knob 404 is continuously rotated until the knob 404 is pressed against the limit block 402, thereby further fixing the limit block 402, thereby increasing the stability of the installation of the screen 3, and the screen 3 is detachable, which is convenient for replacing screens 3 with different sizes of mesh holes or disassembly and maintenance; the setting of the protective box 7 and the protective cover 8 has a protective effect on the driving gear 203 and the driven gear 204, preventing mud and sand from damaging the driving gear 203 and the driven gear 204; the setting of the connecting piece 9 facilitates the installation of the screening bucket body 1 on the shovel frame of the excavator.
