DETAILED DESCRIPTION

[0043] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. The components of the embodiments of the present invention generally described and shown in the drawings here can be arranged and designed in various different configurations.

[0044] Example 1:

[0045] In this embodiment, if Figure 1-2 As shown, the present invention proposes a pre-treatment device for soil remediation, comprising a box body 1, in which a first crushing assembly, a second crushing assembly, a first screening assembly and a second screening assembly are sequentially arranged from top to bottom;

[0050] In this example, the first crushing motor and the second crushing motor drive the first crushing assembly and the second crushing assembly respectively, which are prior art and not shown in the drawings. The first crushing motor and the second crushing motor can be purchased on the market.

[0051] In this embodiment, it is further configured that the first crushing assembly includes a first rotating shaft 21, a first crushing roller 22 and a first crushing tooth 23, the first rotating shaft is connected to the output end of the first crushing motor; the first crushing roller is sleeved on the first rotating shaft, and the first crushing roller rotates coaxially with the first rotating shaft; the first crushing teeth are circumferentially distributed on the first crushing roller.

[0052] In this example, a pair of first rotating shafts and first crushing rollers are provided, and the first rotating shafts are correspondingly connected to the first crushing motor. The two first rotating shafts rotate in opposite directions, the first rotating shaft on the right rotates counterclockwise, and the first rotating shaft on the left rotates clockwise, so as to facilitate the transportation of soil to the center for crushing and extrusion.

[0053] In this embodiment, it is further configured that the first crushing assembly includes a second rotating shaft 31, a second crushing roller 32 and a second crushing tooth 33, the second rotating shaft is connected to the output end of the second crushing motor; the second crushing roller is sleeved on the second rotating shaft, and the second crushing roller rotates coaxially with the second rotating shaft; the second crushing teeth are circumferentially distributed on the second crushing roller.

[0054] In this example, four second rotating shafts and four second crushing rollers are provided. Each second rotating shaft is connected to the second crushing motor. The second rotating shafts rotate counterclockwise, clockwise, clockwise, and clockwise from right to left, respectively, conveying the soil toward the center for crushing and squeezing. The second crushing roller has a smaller diameter than the first crushing roller and has more second crushing teeth than the first, enabling the second crushing assembly to more completely crush the soil.

[0055] In this embodiment, it is further configured that the first screening component includes a first mounting frame 41, a first vibration spring 42, a first screening mesh plate 43 and a first vibration motor 44, the first mounting frame is arranged inside the box; the bottom end of the vibration spring is connected to the first mounting frame, and the first vibration spring is arranged in a circumferential array; the outer bottom of the first screening mesh plate is connected to the top end of the first vibration spring, and the inclination angle of the first screening mesh plate is 15-20 degrees; the first vibration motor is installed below the first screening mesh plate.

[0056] In this embodiment, it is further configured that the second screening assembly includes a second mounting frame 51, a second vibration spring 52, a second screening mesh plate 53 and a second vibration motor 54, and the second mounting frame is arranged inside the box; the bottom end of the vibration spring is connected to the second mounting frame, and the second vibration spring is arranged in a circumferential array; the outer bottom of the second screening mesh plate is connected to the top end of the second vibration spring, and the inclination angle of the second screening mesh plate is consistent with the inclination angle of the first screening mesh plate; the second vibration motor is installed below the second screening mesh plate.

[0057] In this embodiment, a diverter plate 6 is provided between the first crushing assembly and the second crushing assembly, and both ends of the diverter plate are connected to the inner wall of the box. The diverter plate can disperse and transport the soil between the two second crushing rollers, thereby improving the crushing efficiency of the second crushing assembly.

[0058] In this embodiment, a baffle 7 is further provided above the first screening assembly and the second screening assembly, one end of the baffle being connected to the inner wall of the box, which can prevent the soil from being discharged from the screening outlet without being vibrated and screened, thereby improving the screening effect.

[0059] In this embodiment, a fixing frame 10 is further provided at the bottom edge of the box body, and the fixing frame is used to support the box body.

[0060] Example 2:

[0061] In this embodiment, if Figure 1-2 As shown, the side wall of the box is provided with a first screening outlet 11 and a second screening outlet 12, the first screening outlet is installed with a first track 8, and the second screening outlet is installed with a second track 9. The length of the first track can be greater than the length of the second track. Collecting devices are correspondingly provided under the first track and the second track, and the soil is collected by the collecting devices.

[0062] In this example, the highest point of the first screening outlet is lower than the lowest point of the baffle, the lowest point of the first screening outlet is higher than the highest point of the first screening mesh plate, the highest point of the second screening outlet is lower than the lowest point of the baffle, and the lowest point of the second screening outlet is higher than the highest point of the second screening mesh plate.

[0064] In this example, the collecting device can also be replaced by a conveying device, which conveys soil of corresponding particle size and further processes it.

[0065] The working principle of the pre-treatment device for soil remediation is as follows: after the crushing motor and the vibration motor are powered on, the operator pours the soil from the feeding port, and the soil is crushed by the first crushing component, so that the stones and large blocks in the soil are broken. The soil after the primary crushing is diverted by the guide plate and crushed by the second crushing component, so that the larger blocks in the soil are broken. The soil after the secondary crushing falls onto the first screening mesh plate, and the first vibration motor vibrates the first screening mesh plate so that the soil with a particle size smaller than the mesh size of the first screening mesh plate falls to the second screening mesh plate. The soil with a particle size larger than the mesh size of the first screening mesh plate gradually slides downward through the first screening outlet to the first track due to the inclination of the first screening mesh plate under the action of the first vibration motor. Similarly, the soil with a particle size smaller than the mesh size of the second screening mesh plate falls to the discharge port and is collected by the collecting device. The soil with a particle size larger than the mesh size of the second screening mesh plate gradually slides downward through the second screening outlet to the second track due to the inclination of the second screening mesh plate under the action of the second vibration motor.
