[0018] Compared with the prior art, the present invention has the following beneficial effects: 1. In the farmland soil pollution remediation device exemplified by the present invention, during the downward movement of the soil in the trumpet-shaped shell, the rotating plate continuously strikes the soil to crush the soil lumps, repeatedly piles up the soil and forms a thin layer of soil that falls downward, thereby continuously mixing the soil and making the soil remediation liquid evenly distributed in the soil, thereby ensuring the remediation effect of the soil remediation liquid on the soil.
[0019] 2. In the farmland soil pollution remediation device exemplified by the present invention, on the one hand, the strip member causes the soil accumulated on the first side of the rotating plate to slide obliquely upward, thereby increasing the number of times the soil is accumulated on the rotating plate and making the soil remediation liquid evenly distributed in the soil; on the other hand, the strip member causes the soil lumps to move toward the inner wall of the trumpet-shaped shell, and the strip member and the spiral rod pressurize and shear the soil lumps, thereby improving the crushing efficiency of the soil lumps in the soil; on still another hand, the rotating plate drives the spiral rod to rotate through the soil, and the spiral rod scrapes off the soil slurry adhered to the inner wall of the trumpet-shaped shell, thereby preventing the soil from adhering to the inner wall of the trumpet-shaped shell and ensuring that the thin layer of soil on the inner wall of the trumpet-shaped shell falls downward, thereby improving the reliability of the device.
[0020] 3. In the farmland soil pollution remediation device exemplified by the present invention, when bricks and stones are stuck between the edge of the rotating plate and the inner wall of the trumpet-shaped shell, the rotation speed of the rotating plate is reduced, and the moving part rotates compared to the rotating shaft. The rotating moving part causes the elastic part to bend, and the bent elastic part causes the moving part to drive the rotating plate to move downward, and the gap between the edge of the rotating plate and the inner wall of the trumpet-shaped shell becomes larger, so that the bricks and stones between the rotating plate and the trumpet-shaped shell are separated, thereby improving the reliability of the farmland soil pollution remediation device.
[0021] 4. In the farmland soil pollution remediation device of the example of the present invention, the rotation direction of the rotating shaft is the same as the spiral direction of the spiral rod. The soil accumulated on the first side of the rotating plate applies a downward force to the spiral rod, thereby preventing the driving mechanism from stalling due to excessive friction between the spiral rod and the trumpet-shaped shell.

DETAILED DESCRIPTION
[0024] 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 only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.
[0025] Embodiment 1: See also Figure 1-5 The present embodiment discloses a farmland soil pollution remediation device, including a liquid inlet pipe 2, a trumpet-shaped shell 3 with openings at the top and bottom ends, the inner diameter of the trumpet-shaped shell 3 gradually increases from top to bottom, a rotating shaft 1 is installed on the inner wall of the trumpet-shaped shell 3 through a bearing seat and a fixed bracket, the central axis of the rotating shaft 1 coincides with the central axis of the trumpet-shaped shell 3, a driving mechanism 7 for driving the rotating shaft 1 to rotate is installed on the trumpet-shaped shell 3, a liquid guide ring 9 is installed on the rotating shaft 1, and no less than two rotating components are installed at equal angles on the rotating shaft 1.
[0026] The rotating assembly includes a rotating plate 8, one edge of which is fixedly connected to the rotating shaft 1, and a gap is provided between the other edge of the rotating plate 8 and the inner wall of the trumpet-shaped shell 3. The rotating plate 8 has a first side surface and a second side surface, and a liquid distribution pipe 4 is fixed to the second side surface near the inner wall of the trumpet-shaped shell 3. The liquid distribution pipe 4 is provided with a plurality of liquid outlets, and the liquid distribution pipe 4 and the liquid inlet pipe 2 are connected through a liquid guide ring 9.
[0027] Furthermore, the cone angle of the inner wall of the trumpet-shaped housing 3 is 30.0°-130.0°.
[0028] Furthermore, the distance between the edge of the rotating plate 8 and the inner wall of the trumpet-shaped housing 3 is 0.3-2.5 cm.
[0029] The driving mechanism 7 used in the present invention is a common internal combustion engine, electric motor or hydraulic motor in the prior art, and its working method and structure are well-known technologies and will not be described in detail here.
[0030] The working process and principle of this embodiment are: The staff operates the driving mechanism 7, which drives the rotating plate 8 to rotate through the rotating shaft 1. The staff operates the external feeding mechanism to continuously input soil into the opening at the top of the trumpet-shaped shell 3. The staff operates the external liquid pump to continuously input soil remediation liquid into the liquid inlet pipe 2. The soil remediation liquid in the liquid inlet pipe 2 enters the liquid distribution pipe 4 through the liquid guide ring 9, and the soil remediation liquid in the liquid distribution pipe 4 is sprayed through the liquid outlet.
[0031] The first side surface of the rotating plate 8 contacts the soil, and the rotating plate 8 moves the soil toward the inner wall of the trumpet-shaped shell 3, and forms a thin layer of soil on the inner wall of the trumpet-shaped shell 3. The thin layer of soil falls downward after leaving the rotating plate 8, and the soil remediation liquid is sprayed on the soil falling downward through the liquid guide ring 9 and the liquid distribution pipe 4, and then the soil falling downward contacts the first side surface of the rotating plate 8.
[0032] The soil entering the trumpet-shaped shell 3 repeats the following process: the soil accumulates on the first side of the rotating plate 8, the soil forms a thin layer of soil on the inner wall of the trumpet-shaped shell 3, the thin layer of soil leaves the rotating plate 8 and falls downward, the soil remediation liquid is sprayed on the soil falling downward, and the soil falling downward accumulates on the first side of the rotating plate 8.
[0033] Finally, the soil in the trumpet-shaped shell 3 leaves through the opening at the bottom end of the trumpet-shaped shell 3 .
[0034] As the soil in the trumpet-shaped shell 3 moves downward, the rotating plate 8 continuously hits the soil to crush the soil lumps, repeatedly stacking the soil and forming a thin layer of soil that falls downward, thereby continuously mixing the soil and making the soil remediation liquid evenly distributed in the soil, thereby ensuring the soil remediation effect of the soil remediation liquid on the soil.
[0035] The soil remediation liquid in this embodiment is a material commonly used for soil remediation in the prior art. The soil remediation liquid converts pollutants from harmful to harmless or low-toxic through chemical reactions, or the soil remediation liquid reduces pesticide residues in the soil through physical adsorption.
[0036] Embodiment 2: like Figure 3 , 5 As shown, this embodiment discloses a farmland soil pollution remediation device, and its structure is roughly the same as that of the first embodiment, except that, in this embodiment, a plurality of strip members 10 are fixed on the first side surface of the rotating plate 8 along the direction from top to bottom, and the strip members 10 gradually tilt upward in the direction away from the rotating shaft 1.
[0037] Furthermore, the strip 10 is a fixing rod or a raised edge.
[0038] The working process and principle of this embodiment are: During the rotation of the rotating plate 8, the strip 10 causes the soil accumulated on the first side of the rotating plate 8 to slide obliquely upward, thereby increasing the number of times the soil is accumulated on the rotating plate 8 and making the soil repairing liquid evenly distributed in the soil.
[0039] Furthermore, under the premise that the strip 10 makes the soil remediation liquid evenly distributed in the soil, the device can reduce the height of the trumpet-shaped housing 3 and the height of the rotating plate 8, thereby reducing the equipment cost of the device.
[0040] Embodiment three: like Figure 2-5 As shown, this embodiment discloses a farmland soil pollution remediation device, and its structure is roughly the same as that of the second embodiment, except that, in this embodiment, a rotating spiral rod 6 is provided in the trumpet-shaped shell 3, and the outer edge of the spiral rod 6 is slidably fitted with the inner wall of the trumpet-shaped shell 3, and a gap is provided between the inner edge of the spiral rod 6 and the rotating plate 8.
[0041] Furthermore, the distance between the inner edge of the spiral rod 6 and the edge of the rotating plate 8 is 0.1-2.0 cm, and the thickness of the spiral rod 6 is 1.0-2.5 cm.
[0042] The working process and principle of this embodiment are: When soil lumps accumulate on the first side of the rotating plate 8, the strip 10 on the first side of the rotating plate 8 moves the soil lumps toward the inner wall of the trumpet-shaped shell 3. The strip 10 prevents the soil lumps from sliding up and down along the first side. The strip 10 and the spiral rod 6 pressurize and shear the soil lumps, thereby improving the crushing efficiency of the soil lumps in the soil.
[0043] The rotating plate 8 drives the spiral rod 6 to rotate through the soil, and the spiral rod 6 scrapes off the soil mud adhered to the inner wall of the trumpet-shaped shell 3, avoiding the soil from adhering to the inner wall of the trumpet-shaped shell 3, ensuring that the thin layer of soil on the inner wall of the trumpet-shaped shell 3 falls downward, thereby improving the reliability of the device.
[0044] Furthermore, by adjusting the weight of the screw rod 6 or adjusting the extrusion force between the screw rod 6 and the trumpet-shaped housing 3 , the angular velocity of the screw rod 6 is made lower than the angular velocity of the rotating plate 8 .
[0045] Embodiment 4: like Figure 5 , 6 As shown, this embodiment discloses a farmland soil pollution remediation device. On the basis of embodiment one, embodiment two or embodiment three, the edge of the rotating plate 8 and the rotating shaft 1 of this embodiment are connected through an installation assembly, and the installation assembly includes an elastic member 13, a movable member 12 rotatable around the rotating shaft 1 and a fixed member 14 fixed on the rotating shaft 1, the fixed member 14 is located below the movable member 12, the edge of the rotating plate 8 and the movable member 12 are fixedly connected, and the fixed member 14 and the movable member 12 are connected through the elastic member 13.
[0046] Further, the elastic member 13 is an elastic rod, an elastic sheet or an elastic shock absorber, the moving member 12 is a first circular ring, and the fixing member 14 is a second circular ring or a fixing block.
[0047] The working process and principle of this embodiment are: When bricks and stones are stuck between the edge of the rotating plate 8 and the inner wall of the trumpet-shaped shell 3, the rotation speed of the rotating plate 8 decreases, and the moving part 12 rotates compared to the rotating shaft 1. The rotating moving part 12 causes the elastic part 13 to bend, and the bent elastic part 13 causes the moving part 12 to drive the rotating plate 8 to move downward. The gap between the edge of the rotating plate 8 and the inner wall of the trumpet-shaped shell 3 becomes larger, so that the bricks and stones between the rotating plate 8 and the trumpet-shaped shell 3 are separated, thereby improving the reliability of the farmland soil pollution remediation device.
[0048] Embodiment five: like Figure 3 , 5 As shown, this embodiment discloses a farmland soil pollution remediation device, and its structure is roughly the same as that of the third embodiment, except that a support member 11 is fixed to the inner wall of the trumpet-shaped shell 3 of this embodiment, and the support member 11 is a circular ring, and the top side of the support member 11 is in sliding contact with the bottom end of the spiral rod 6.
[0049] When the screw rod 6 rotates, the friction between the screw rod 6 and the trumpet-shaped housing 3 , and the friction between the screw rod 6 and the ring make the angular velocity of the screw rod 6 lower than the angular velocity of the rotating plate 8 .
[0050] Embodiment six: like Figure 3 , 5 As shown, this embodiment discloses a farmland soil pollution remediation device, and its structure is roughly the same as that of the third embodiment, except that this embodiment also includes a support member 11, which is a bearing, and the bottom end of the spiral rod 6 and the inner wall of the trumpet-shaped shell 3 are rotatably connected through the bearing.
[0051] When the screw rod 6 rotates, the friction between the screw rod 6 and the trumpet-shaped housing 3 causes the angular velocity of the screw rod 6 to be lower than the angular velocity of the rotating plate 8 .
[0052] Embodiment seven: like Figure 2-5 As shown, this embodiment discloses a farmland soil pollution remediation device, and its structure is roughly the same as that of the fifth or sixth embodiment, except that the rotation direction of the rotating shaft 1 in this embodiment is the same as the spiral direction of the spiral rod 6, and the soil accumulated on the first side of the rotating plate 8 exerts a downward force on the spiral rod 6, thereby preventing the friction between the spiral rod 6 and the trumpet-shaped shell 3 from being too large and causing the driving mechanism 7 to stop rotating.
[0053] Embodiment eight: like Figure 2-5 As shown, this embodiment discloses a farmland soil pollution remediation device, whose structure is roughly the same as that of the first embodiment, except that a nozzle 5 is installed on each liquid outlet of the liquid distribution pipe 4 to spray the soil remediation liquid in the liquid distribution pipe 4 evenly.
[0054] While the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations can be made to the embodiments without departing from the principles and spirit of the invention.
