(lll) Advantageous Effects Compared with the prior art, the present invention provides a device for treating low and medium concentration cadmium polluted farmland soil with earthworms, and has the following beneficial effects:
1. An electric motor operates to drive a screw rod to rotate, and the screw rod rotates and moves along the nut, and further drives the electric motor to move; the electric motor drives a pressing plate to move when movable rightwards, and the pressing plate moves to press a corrugated cylinder, so that moisture in the corrugated cylinder is pressed and flows along an infusion tube to the interior of a hollow plate, and then is sprayed into the soil by means of nozzles, thereby maintaining the soil in a damp state, and providing a damp environment for earthworms to survive in the soil.
2. The rotation reset of a rotatable plate is facilitated by means of the torsion of the torsion springs, the rotatable plate rotates and drives round bars to move, so as to push movable blocks to move, so that touch switches are closed; under the action of the torsion of the torsion springs, the rotatable plate rotates and resets, the rotatable plate rotates to drive the round bars to move, the round bars moves to press the movable blocks, so that the movable blocks move upwards, the movable blocks move upwards to drive the T-shaped round bar to move upwards, so as to press the spring |; the movable blocks move upwards to drive the connecting rod to move upwards, so as to press the touch switch to close; and the temperature regulators and the heating plates start to work, thereby facilitating heat preservation of the soil inside the outer box body.
3. The rotatable rods are pressed by movable rods, and the rotatable rods rotate to adjust the positions of temperature regulators and temperature measurement probes; when the movable rods move upwards, pressing blocks are separated from the rotatable rods; under the action of the elastic force of a spring II, a T-shaped round block pulls the temperature regulator to move downwards so as to further press the rotatable rods, so that the rotatable rods rotate and resets; the temperature modulators move downwards and drive the temperature measurement probes to move downwards and insert same into the soil, so as to measure the temperature inside the soil; the temperature regulators are set at a temperature suitable for the survival of the earthworms; and when the temperature measured by the temperature measurement probes is lower than a set temperature, the temperature regulators control the operation of a heating plate to heat the soil until the temperature of the soil reaches a suitable temperature, thereby providing the earthworms with a survival environment inside the soil.
4. Moisture is added into the interior of the corrugated cylinder by means of a check valve, facilitating spraying water into the soil; an electric motor operates to drive a screw rod to rotate, the screw rod rotates and moves along a nut, so as to drive both the L-shaped plate and the electric motor to move leftwards; the electric motor moves leftwards to drive a pressing plate to move leftwards so as to stretch the corrugated cylinder, so that a negative pressure is formed in the corrugated cylinder; and an external water delivery device adds moisture into the interior of the corrugated cylinder by means of the check valve, thus improving the convenience of the operation of the device.
5. The movable blocks are pulled downward by means of the elastic force of the spring |, so that the connecting rod is driven to move downwards, and the rotatable rods are pressed, so that the temperature regulators and the temperature measurement probes move upwards, and the temperature measurement probes are separated from the soil, thereby avoiding the problem that the temperature measurement probes are damaged caused by the collision with the temperature measurement probes during the movement of the L-shaped plate.

When it is necessary to pull the L-shaped plate 2 into the outer box body 1, the electric motor 6 operates to drive the screw rod 3 to rotate in the reverse direction, so that the screw rod 3 moves in the reverse direction along the nut 4, the screw rod 3 moves to drive the L-shaped plate 2 and the electric motor 6 to move in the reverse direction, the L-shaped plate 2 moves rightwards into the outer box body 1 and is separated from the rotatable plate 7; under the action of the torsion of the torsion spring 9, the rotatable plate 7 rotates and resets, the rotatable plate 7 rotates to drive the round rod 10 to move, the round rod 10 moves to press the movable block 15, so that the movable block 15 moves upwards, and the movable block 15 moves upwards to drive the T-shaped round rod 13 to move upwards, so as to press the spring | 14; the movable block 15 moves upwards to drive the connecting rod 16 to move upwards, and then press the contact switch 17, so that the contact switch 17 is closed, and the temperature regulator 21 and the heating plate 26 begin to operate; during the upward movement of the movable rod, the pressure block 18 is separated from the rotatable rod 19; under the action of the elastic force of the spring II 25, the T-shaped round block 24 pulls the temperature regulator 21 to move downwards, and then presses the rotatable rod 19 to make the rotatable rod 19 rotate and reset; the temperature regulator 21 moves downwards to drive the temperature measurement probe 22 to move downwards and insert into the soil, so as to measure the temperature inside the soil, and set a temperature suitable for the survival of earthworms on the temperature regulator 21; when the temperature measured by the temperature measurement probe 22 is lower than the set temperature, the temperature regulator 21 controls the heating plate 28 to heat the soil until the temperature of the soil reaches the appropriate temperature; when the electric motor 6 moves rightwards to drive to the pressing plate 31 to move, and the pressing plate 31 moves to press the corrugated cylinder 30, so that moisture in the corrugated cylinder 30 is squeezed and flows along the infusion pipe 29 to the interior of the hollow plate 27, and is sprayed into the soil by means of nozzles 28, thereby maintaining the soil in a damp state.
The electrical elements mentioned herein are all electrically connected to an external master controller and a 220V mains supply, and the master controller can be a conventional known device controlled by a computer, etc.
In the description herein, it should be noted that, unless specified or limited otherwise, the terms "connecting" and "connected" should be interpreted broadly, and may be, for example, fixed connections, detachable connections, or integral connections; may also be mechanical or electrical connections, may also be direct connections, and may also be indirect connections by means of intervening structures. The specific meanings of the described terms in the present invention can be understood by a person skilled in the art according to specific situations.
In the description herein, it should be noted that relationship terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or sequence between these entities or operations. Furthermore, the terms "comprise", "include" or any other variant thereof are intended to cover a non-exclusive inclusion, so that a process, a method, an article, or a device that includes a series of elements not only includes those elements, but also includes other elements that are not explicitly listed, or further includes elements inherent to the process, the method, the article, or the device.
Although the embodiments of the present invention have been shown and described, it would be appreciated by a person skilled in the art that various changes, modifications, substitutions and modifications can be made to these embodiments without departing from the principle and spirit of the present invention, and the scope of the invention is limited by the appended claims and their equivalents.
