AI Technical Summary
During spray purification of existing heavy metal contaminated soil, the soil is in a standstill state, resulting in the inability to mix well with the soil, affecting the purification effect.
A leaching device for treating heavy metal contaminated soil was designed. The limit block is driven by a worm, which drives the connecting rod to rotate, and the connecting rod drives the drum to mix the soil and the potion evenly. At the same time, the worm drives the worm gear and the eccentric wheel to rotate, driving the support rod and the limit sleeve to move, so that the connecting rod and the drum move back and forth while rotating, ensuring that the soil and the potion are fully mixed.
Through the design of this device, the soil and the potion can be fully mixed, which improves the purification efficiency of the soil and solves the problem of poor mixing of the potion and the soil in the prior art due to the standing of the soil.

DETAILED DESCRIPTION
[0019] The present invention is not limited by the following embodiments, and specific implementation methods can be determined according to the technical solution of the present invention and actual conditions.
[0020] The present invention is further described below in conjunction with the embodiments and drawings:
[0021] like Figure 1-4 As shown, a leaching device for treating heavy metal contaminated soil comprises a base 1, a motor 3 is arranged on the right side above the base 1, a worm 4 is fixedly connected to the output shaft end of the motor 3, a connecting rod 5 is movably sleeved on the output end of the worm 4, a rotating drum 6 is connected to the end of the connecting rod 5 away from the worm 4, a support seat 7 is connected to the left side of the base 1, and the rotating drum 6 is movably connected above the support seat 7; a feeding port 9 is arranged on the outside of the rotating drum 6; a mounting frame 2 is arranged above the base 1, and a moving component is arranged at the bottom of the mounting frame 2;
[0022] The moving assembly includes a rotating rod 10, an eccentric wheel 11, and a worm wheel 12 meshing with the worm 4. The eccentric wheel 11 is arranged on the outside of the worm wheel 12. A limiting sleeve 13 is sleeved on the outside of one end of the connecting rod 5 close to the worm 4. A support rod 14 is arranged on the outside of the limiting sleeve 13. The upper end of the support rod 14 is movably connected to the upper wall inside the mounting frame 2. The outer side of the support rod 14 is connected to the eccentric wheel 11 through the rotating rod 10.
[0023] During operation, the contaminated soil is placed inside the rotating drum 6, and the motor 3 drives the worm 4 to rotate, the worm 4 drives the connecting rod 5 to rotate, and the connecting rod 5 drives the rotating drum 6 to rotate, so that the soil and the medicine in the rotating drum 6 are evenly mixed, and the worm 4 drives the worm wheel 12 to rotate, and the worm wheel 12 drives the eccentric wheel 11 to rotate, and the eccentric wheel 11 drives the support rod 14 to move through the rotating rod 10, thereby further driving the limit sleeve 13 to move, so that the connecting rod 5 moves left and right, thereby, the connecting rod 5 can move left and right while rotating, so that the soil and the medicine inside the rotating drum 6 are fully mixed, and the soil purification efficiency is improved.
[0024] like Figure 3 , 4 As shown, a group of limit blocks 15 are symmetrically arranged along the radial direction on the outer side of one end of the worm 4 close to the connecting rod 5, and a limit groove 16 is arranged on the connecting rod 5 corresponding to the position of the limit block 15, and the limit block 15 is sleeved inside the limit groove 16. The length of the limit groove 16 is greater than the movable length of the worm 4, so as to prevent the connecting rod 5 from sliding out from the outer side of the worm 4 during the movement, thereby affecting the movement of the rotating drum 6.
[0025] like Figure 1 As shown, moving wheels 17 are provided at the four corners of the bottom of the support seat 7, and support rods 18 are provided at the front and rear sides of the upper part of the support seat 7.
