Description

Technical Field

[0001] This utility model relates to the field of soil screening technology, specifically a drum-type soil screening machine. Background Technology

[0002] Soil screening machines are mainly used for classifying and separating impurities from soil materials.

[0003] Currently, conventional soil screening machines have the following problems: the mesh size of the screen used for screening cannot be adjusted at any time according to the size of impurities in the soil; the soil that needs to be screened is often clump together, making it difficult for conventional screening machines to screen.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a drum-type soil screening machine in order to achieve a more practical purpose. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a drum-type soil screening machine to solve the problems mentioned in the background art.

[0006] In view of the above problems, the technical solution proposed by this utility model is: a drum-type soil screening machine, including a base, with a left sliding seat and a right sliding seat respectively provided at both ends of the base. The left sliding seat is provided with a first servo motor with its output end facing right, and the right sliding seat is provided with a second servo motor with its output end facing left. The output end of the first servo motor is fixedly connected to a left connecting shaft, and the output end of the second servo motor is fixedly connected to a right connecting shaft. An outer screen cylinder is fixedly connected to the end of the left connecting shaft away from the first servo motor. An inner screen cylinder is provided inside the outer screen cylinder. The arc surfaces of the outer screen cylinder and the inner screen cylinder are both provided with uniformly distributed screen holes. The outer screen cylinder and the inner screen cylinder cooperate to screen the soil. A conveyor belt is laid below the outer screen cylinder.

[0007] As a further description of the above technical solution: both ends of the top surface of the base are provided with sliding grooves, and the bottom of the left sliding seat and the bottom of the right sliding seat are provided with pulleys, which cooperate with the sliding grooves.

[0008] By adopting the above technical solution, it is easy to adjust the positions of the left and right sliding seats.

[0009] As a further description of the above technical solution: a turntable is provided in the middle of the left sliding seat, so that the upper part of the left sliding seat can rotate around the turntable.

[0010] By adopting the above technical solution, it is easy to rotate the left sliding seat, thereby driving the outer screen cylinder and the inner screen cylinder to rotate, which in turn facilitates feeding material from the opening provided at the end of the outer screen cylinder away from the left sliding seat.

[0011] As a further description of the above technical solution: both the outer screen cylinder near the right sliding seat and the inner screen cylinder near the right sliding seat are provided with openings, and the outer wall of the inner screen cylinder cooperates with the inner wall of the outer screen cylinder.

[0012] As a further description of the above technical solution: an arc groove is provided at one end of the outer screen cylinder near the left sliding seat, and a sliding rod is fixedly connected at one end of the inner screen cylinder near the left sliding seat. The sliding rod is in clearance fit with the arc groove, and the sliding rod can slide in the arc groove. The inner screen cylinder is fixed inside the outer screen cylinder by a bolt provided at the end of the sliding rod.

[0013] By adopting the above technical solution, the inner screen cylinder can be rotated inside the outer screen cylinder by moving the sliding rod. The size of the filter holes of the outer screen cylinder can be adjusted by the inner screen cylinder according to the size of the soil impurities to be screened during actual use, and the inner screen cylinder can be fixed by bolts.

[0014] As a further description of the above technical solution: the left sliding seat is provided with a bearing on the side near the outer screen cylinder, the outer ring of the bearing is provided with a connecting rod and is fixedly connected to the outer screen cylinder, and the inner ring of the bearing is fixedly connected to the left sliding seat.

[0015] By adopting the above technical solution, the connecting rod, in conjunction with the bearing, can provide support for the outer screen cylinder without affecting its rotation.

[0016] As a further description of the above technical solution: the right connecting shaft extends into the inner screen cylinder, and brush rods are evenly distributed on the right connecting shaft.

[0017] By adopting the above technical solution, the soil placed in the inner screen cylinder can be broken up by brushing the soil with a brush rod, and the soil can be effectively prevented from clogging the screen holes.

[0018] As a further description of the above technical solution: a connecting block is provided at one end of the right sliding seat near the inner screen cylinder, a disc is fixedly connected above the connecting block, the right connecting shaft passes through the disc, and ball bearings are evenly provided on the arc surface of the disc near the inner screen cylinder.

[0019] By adopting the above technical solution, the disc can play a role in isolation and support, preventing soil from leaking out of the inner screen cylinder. When the inner screen cylinder rotates, the ball bearings on the disc can reduce friction.

[0020] As a further description of the above technical solution: the first servo motor and the second servo motor rotate in opposite directions.

[0021] By adopting the above technical solution, it is beneficial to improve screening efficiency and facilitate the separation of soil by brush rod.

[0022] Compared with the prior art, the beneficial effects of this utility model are as follows: the inner screen cylinder is rotated inside the outer screen cylinder by moving the sliding rod. The size of the screen hole of the outer screen cylinder is adjusted by the inner screen cylinder according to the size of the soil impurities to be screened during actual use. The left rotating shaft drives the brush rod provided on the right rotating shaft. When the inner screen cylinder rotates, the brush rod can brush the soil placed inside the inner screen cylinder, which can break up the clumps in the soil and effectively prevent the soil from clogging the screen hole, thus improving the screening efficiency and screening effect.
