As shown in fig. 1 to 4, the main body part of the invention is a middle mixer 2, the mixer 2 is supported by a plurality of rollers 6 on a bracket 1, and one roller 6 is driven by a motor to rotate; enabling the mixer 2 to rotate clockwise; the mixer 2 is composed of an inner cylinder 201 and an outer cylinder 202, wherein side plates 203 are arranged in front of and behind the area between the inner cylinder 201 and the outer cylinder 202, so that a large annular space is formed, and the space is divided into a plurality of chambers 205 by a plurality of radially and circumferentially uniformly distributed partition plates 204; a rotatable stirring shaft 206 is arranged in each chamber 205, and an opening corresponding to each chamber 205 is arranged on the outer cylinder 202;

the upper left of the mixer 2 is provided with a feed hopper 3, the upper right of the mixer is symmetrically provided with a feed hopper 3, and the opening at the lower end of the feed hopper 3 is consistent with the opening of each cavity 205 in size; each feed hopper 3 is inserted with a movable baffle plate 7, and the blanking speed of the feed hopper 3 can be adjusted by pulling the baffle plates 7;

the below of blender 2 has an arc 5, and arc 5 is fixed to be set up, and arc 5 parcel is in the outside of the lower part of outer drum 202, and be filter screen portion 501 under the arc 5, the left side of filter screen portion 501 is provided with row's cinder notch 502, and the right side of filter screen portion 501 is to the extension to guarantee that soil fully sieves.

In order to realize the installation and rotation of each stirring shaft 206 in the stirrer 2, the inner end of each stirring shaft 206 passes through the inner cylinder 201, the inner cylinder 201 is provided with a reinforcing sleeve sleeved outside the stirring shaft 206, and the inner end of each stirring shaft 206 is provided with a secondary bevel gear 207; a front-rear direction driving shaft 209 is mounted on the bracket 1, and a main bevel gear 208 which is simultaneously engaged with the plurality of auxiliary bevel gears 207 is mounted on the driving shaft 209; the driving shaft 209 is driven to rotate by a motor.

In order to realize the spraying of the spray header 4, the rear of the spray header 4 is connected with a hose, the other end of the hose is arranged in the container, and the middle part of the hose is connected with a water pump.

In order to avoid mixing the material discharged from the filter screen part 501 with the material discharged from the slag discharge port 502; the left end of the filter screen part 501 is provided with a vertical baffle 9.

In order to avoid material leakage, the left end and the right end of the arc-shaped plate 5 are fixed with the side walls of the left feeding hopper 3 and the right feeding hopper 3.

According to the invention, the mixer 2 continuously rotates clockwise, the left feeding hopper 3 is used for placing soil to be treated, and the right feeding hopper 3 is used for placing solid soil restoration agent; the left and right conveyor belts are arranged in the factory building to continuously feed materials into the left and right feed hoppers 3 respectively, so that continuous automatic feeding is realized.

In order to save energy consumption, the driving shaft 209 can be selected to rotate clockwise, and the rotation resistance of the roller 6, that is, the rotation resistance of the outer cylinder 202, can be adjusted, at this time, the driving shaft 209 can drive the auxiliary bevel gear 207 to rotate and can also drive the whole mixer 2 to rotate clockwise, so that one motor can drive the whole system to work. However, since the rotational resistance of the sub bevel gear 207 and the resistance to the rotation of the entire pulsator 2 are not determined at this time, the relationship between the rotation of the sub bevel gear 207 and the revolution speed of the pulsator 2 is not determined, but the effect is limited although it can be operated.

Therefore, for more stable operation, the driving shaft 209 is selected to rotate anticlockwise, and one of the rollers 6 is driven by the motor to drive the whole mixer 2 to rotate clockwise, so that the rotation speed of the whole mixer 2 is fixed, and the rotation speed of the auxiliary bevel gear 207 is enhanced by superposition under the action of the two motors, so that the rotation speed of the auxiliary bevel gear 207 is improved, and the crushing effect is improved.

When the stirrer 2 starts to rotate, firstly, the soil to be treated in the left feed hopper 3 falls into one of the chambers 205 in the stirrer 2 and is stirred and crushed by the stirring shaft 206 in the chamber 205, and then the soil to be treated rotates to the position right above the stirring shaft along with the rotation of the stirrer 2, and at the moment, liquid water or repairing agent can be sprayed by the spray header 4 as required for stirring again; the mixer 2 continues to rotate, and at the moment, the solid soil restoration agent in the feed hopper 3 on the right side falls into the soil and is stirred; the mixer 2 continues to rotate, so that the soil and the repairing agent mixed in the mixer can be fully mixed; meanwhile, in the stirring process, the stirrer 2 continuously rotates, so that the position of each chamber 205 also changes, and the existence of stirring dead angles can be avoided.

When the stirring is completed, the stirrer 2 is transferred to the lower part, and the soil after the crushing and the mixing of the repairing agent passes through the filter screen part 501 of the arc-shaped plate 5 and falls below the stirrer 2; the large-particle sundries contained in the mixer 2 can be temporarily stored above the filter screen part 501, and along with the continued rotation of the mixer 2, the fine-particle soil in the mixer 2 completely passes through the filter screen part 501; the large-particle sundries continue to rotate to the slag discharge port 502 and are discharged from the slag discharge port 502; realizes the separation of large-particle sundries.

The method repeatedly operates, and continuous automatic treatment of soil can be realized.

The falling speed of soil and the falling speed of the soil remediation agent can be adjusted according to the requirement, and the size of the falling opening of the feeding hopper 3 can be adjusted by adjusting the position of the baffle plate 7 below the feeding hopper 3, so that the falling speed is adjusted, and the self-defined soil remediation agent is added.

The device can select either a solid or liquid repairing agent, and both agents can be used at the same time; for example, when repairing acidic dry soil, lime powder is needed to repair, part of water can be sprayed from the spray header 4 to improve the humidity of the soil, so that the full mixing of the soil and the lime powder is facilitated. For example, in the case of restoration of soil lacking organic matter, a liquid restoration agent is not required, and only a biological strain of powder or solid restoration agent particles or the like is required to be added and sufficiently stirred.

In this device, through set up filter screen portion 501 and be located the sediment mouth 502 of filter screen portion 501 left side on arc 5, can realize the screening to fine particle soil, discharge the debris of macroparticle by sediment mouth 502 simultaneously to macroparticle that the card was in filter screen portion 501 can clear the scraping under the rotation of outer drum 202, has avoided the jam of filter screen portion 501.

The device is integrally designed, has a light structure, small occupied space, can continuously and automatically treat soil, does not need the cooperation of multiple devices in a pipelining manner, and has low energy consumption, good treatment effect and complete functions.
