The motor 8 and the belt pulley 81 installed on the output shaft of the motor are installed at the upper end of the accommodating case 1, the end of the shaft body 21 of the screw shaft 2 extends to the outside of the accommodating chamber 11 and is in transmission connection with the motor 8 through the belt pulley 81, and meanwhile, the motor 8 is also provided with the motor speed detector 9 which can be used for detecting the rotating speed of the screw shaft 2, thereby achieving the effects of detection and feedback.

In this embodiment, an overflow liquid density detector 15 is provided, the overflow liquid density detector 15 is installed at the first overflow port 13 or/and the second overflow port 14, and the overflow liquid density detector 15 is used for detecting the particle size of the discharged soil;

the output end of the lifting assembly is connected to the accommodating shell 1, and the inclination angle of the spiral shaft element 2 is controlled through the lifting action of the lifting assembly;

it should be noted that, because the screw shaft 2 is disposed in the accommodating chamber 11, the screw shaft 2 can be adjusted by the lifting assembly controlling the position relationship of the accommodating housing 1, specifically, a hydraulic component 6 is disposed at one end of the bottom of the accommodating housing 1, a first support frame 3 is fixedly connected to the bottom of the other end, and a base 5 is also disposed, the hydraulic component 6 is mounted on the base 5 through a base 7 disposed outside, in practice, the hydraulic component 6 can be a hydraulic cylinder but is not limited thereto, a cylinder body thereof is fixedly connected to the base 5 through the base 7, an end of an output shaft 61 thereof is rotatably connected to a lower end surface of the accommodating housing 1, a second support frame 4 is vertically and fixedly connected to the other end of the base 5, the second support frame 4 is rotatably connected to the first support frame 3, so that when the hydraulic component 6 at one end is jacked up through the output shaft 61 thereof, the accommodating housing 1 can be rotated around a connecting shaft of the first support frame 3 and the second support frame 4, similarly, the hydraulic component 6 can also rotate the accommodating shell 1 through the retracting action of the output shaft 61, so as to achieve the effect of rotating the spiral shaft component 2 by the preset inclination angle;

the lifting assembly adjusts the lifting action amplitude in real time according to the soil particle size detected by the overflow liquid density detector 15 so as to drive the soil particle size discharged from the first overflow port 13 and the second overflow port 14 to be within a preset particle size range;

here, a person skilled in the art can understand that, in the present application, the controller 10 is provided, before initial use, a preset adjustment instruction is written in a storage unit of the controller 10, so as to perform automatic lifting and lifting amplitude actions of the hydraulic part 6 according to the preset adjustment instruction, where the lifting amplitude can be understood as the telescopic length of the output shaft 61, and the control of the inclination angle is realized by controlling the telescopic length;

for example, after the soil in the solid-liquid mixed state enters the containing chamber 11 from the feeding hole 12, the screw shaft member 2 has an initial inclination angle at this time, and the soil with different particle sizes is discharged from the first overflow port 13 and the second overflow port 14 respectively in the rotation process, during the discharge process, the overflow liquid density detector 15 detects the soil density in the solid-liquid mixed state at the first overflow port 13 or/and the second overflow port 14 in real time, so as to determine the particle size of the discharged soil particles, the detection information at this time is sent to the controller 10, the controller 10 calculates, according to a preset algorithm model, which inclination angle the screw shaft member 2 in the current state is at is in a preset range, generally, when the inclination angle is smaller (i.e. the screw shaft member 2 is closer to horizontal), the particle size distribution of the soil discharged at the first overflow port 13 and the second overflow port 14 is closer, at the moment, the inclination angle needs to be increased to drive the soil discharged from the first overflow port 13 and the second overflow port 14 to be distributed in a preset large particle and a preset small particle; otherwise, the same principle is carried out; after the controller 10 calculates corresponding adjustment information, an adjustment instruction for controlling the telescopic length of the hydraulic part 6 is generated, the hydraulic part 6 is controlled by the adjustment instruction, and finally the grading effect of the soil particle size is achieved. Here we can see that the overflow liquid density detector 16 and the lifting assembly are used in a cooperative relationship and in combination with the use of the controller 10 to effect the dynamic adjustment.

Meanwhile, a height detection sensor 18 can be further installed at the bottom of the accommodating shell 1, in the lifting adjustment process of the accommodating shell 1, the height position of the accommodating shell 1 can be dynamically detected in real time through the height detection sensor 18, so that the change of the inclination angle of the accommodating shell is calculated according to a preset algorithm model, the height detection sensor 18 is electrically connected with the controller 10, and the controller 10 verifies whether the telescopic length of the hydraulic part 6 is accurate or not according to the height information fed back by the height detection sensor 18.

In another embodiment, the screw shaft 2 includes a shaft body 21 disposed along the length direction of the accommodating chamber 11, the shaft body 21 has a first connecting end 211 and a second connecting end 212 far away from the first connecting end 211, wherein the first connecting end 211 is connected to the pulley 81, the second connecting end 212 is rotatably connected to one end of the accommodating housing 1, and the plurality of blades 22 disposed in the direction from the first connecting end 211 to the second connecting end 212 and the shaft body 21 form the screw shaft 2 with a conical shape as a whole. Here, the blades 22 may be regarded as a semicircular sheet structure with a certain bending range, the inner side surface of the semicircular sheet structure is continuously bent and fixed around the circumference of the shaft body 21 and is connected with the adjacent blades 22 in a seamless manner, and the outer side surface is formed with an arc-shaped edge surface 220, in this embodiment, the blade 22 near the first overflow port 13 is regarded as a head-end blade 224, the blade near the second overflow port 14 is regarded as a tail-end blade 223, the maximum length from the edge surface 220 of the two blades 22 to the shaft body 21 is gradually increased along with the direction of the head-end blade 224 to the tail-end blade 223, and a conical structure of the screw shaft member 2 is formed. Here, the number of the vanes 22 disposed on the shaft body 21 is not limited to a specific number, and meanwhile, the edge surfaces 220 thereof are equally spaced and close to the bottom surface of the accommodating chamber 11, so that the close arrangement can effectively ensure that the soil in a solid-liquid mixed state can respectively flow to the first overflow port 13 and the second overflow port 14 under the rotation of the screw shaft member 2;

On the other hand, the first overflow port 13 is disposed at the upward position facing the accommodating chamber 11, and the second overflow port 14 is disposed at the position relatively below the accommodating chamber, so that the soil discharged from the second overflow port 14 has a high water content, and the overflow liquid density detector 15 is mounted at the position to detect the result more objectively and effectively, thereby improving the detection accuracy.

An overflow liquid flow velocity detector 16 is also installed at the second overflow port 14 for detecting the flow velocity of the soil, it should be noted that the overflow liquid flow velocity detector 16 is also electrically connected with the controller 10, and according to the detection result, the controller 10 controls the rotation speed of the motor 8, it should be understood that the faster the rotation speed of the motor 8 is, the faster the solid-liquid mixed state soil flow velocity flowing out from the second overflow port 14 is, and vice versa.
