[0002] Geotechnical engineering is an important part of civil engineering. According to statistics, it includes geotechnical engineering investigation, design, testing, construction and monitoring, involving the whole process of engineering construction. It is of great significance in various constructions such as housing, municipal administration, energy, water conservancy, roads, shipping, mining, national defense, etc. Geotechnical engineering is a general term for any kind of rock and soil that makes up the earth's crust from the perspective of engineering construction. Geotechnical engineering can be subdivided into five categories: hard (hard rock), sub-hard (soft rock), weakly connected, loosely connected, and with special composition, structure, state and properties.

[0003] The mined rock and soil basically need to be crushed and processed. Conventional rock and soil processing methods generally adopt a multi-step, multi-process, and multi-device separate processing method, which not only increases the producer's rock and soil production and processing costs, but also has low efficiency in separating stones and fine materials, so there are shortcomings.

[0012] A further improvement is that a notch is provided on one side of the screening disc, and the notch is aligned with the mouth of the screening hole.

[0013] Further improvement is that: the screening assembly includes a driving motor, a toggle plate and a crushing body, the bottom of the driving motor is fixedly connected to the inner bottom of the crushing tank, the top of the driving motor output shaft is fixedly connected to a driving rod, the center of the toggle plate is fixedly connected to a first fixed ring, four toggle plates are arranged in a ring shape around the first fixed ring, the toggle plate is arranged on the upper part of the screening disc, the toggle plate is fixedly connected to the driving rod through the first fixed ring, the bottom of the crushing body is fixedly connected to the top of the driving rod, and the crushing body is matched with the top opening of the crushing tank.

[0014] A further improvement is that the toggle plate is arranged to be inclined at 15 degrees, and the outer edge of the toggle plate is close to the inner wall of the screening disc.

[0015] A further improvement is that a conical cap is sleeved on the upper part of the driving motor, and the conical cap is arranged below the screening plate.

[0018] By adopting the above technical solution, the beneficial effects of the utility model are:

[0019] 1. The driving motor drives the crushing body to rotate at the top of the crushing tank. At this time, the toggle plate also rotates synchronously. The stone to be crushed is poured into the mouth of the crushing tank for crushing and falls onto the screening plate. The fine material will leak out, and the larger pieces of stone will be discharged from the screening hole by the toggle plate and then transported away by the conveyor. It can not only grind and crush the stone, but also separate the stone and fine material at the same time, which improves the separation efficiency, requires less power source, has low crushing cost, and is easy for personnel to operate.

[0020] 2. By arranging a cleaning plate driven by a driving motor at the bottom of the screening disc, clogging of the holes of the screening disc can be avoided.

[0021] 3. By setting the crushing body as a cone, the stone can be crushed in stages, making the crushed pieces smaller and easier to separate. BRIEF DESCRIPTION OF THE DRAWINGS
