The core innovation of the embodiment is that the embodiment further comprises a plough, a conveying cylinder 6 and a stirring member 7, wherein the plough is also a cylinder body 4, the cylinder body 4 is arranged along the ground, that is, the cylinder body 4 is horizontally arranged or substantially horizontally arranged, at least a part of the cylinder body 4 is below the ground, and the cylinder body 4 is arranged along the front-rear direction of the vehicle body 1, so that a conveying channel 5 for conveying the original soil is formed in the cylinder body 4, in the process that the vehicle body 1 drives the cylinder body 4 to advance, the cylinder body 4 advances along with the vehicle body 1, so that the original soil enters from the front end of the cylinder body 4 and is discharged from the rear end, so that the cylinder body 4 has small resistance when advancing although the cylinder body 4 is inserted into the ground, meanwhile, the top surface of the middle part of the cylinder body 4 is connected with the conveying cylinder 6, the other end of the conveying cylinder 6 is connected with the conveying mechanism 3, or in other words, the conveying cylinder 6 is part of the conveying mechanism 3, the amendment enters into the cylinder body 4 along the conveying cylinder 6, and the cylinder body 4 has the original soil, so that the amendment falls on the surface of the original soil. Meanwhile, the stirring member 7 is arranged, the stirring member 7 is used for mixing the original soil conveyed by the cylinder body 4 and the amendment, and the most common stirring member 7 is a stirring screw, for example, a stirring screw is arranged in the middle part of the cylinder body 4, the bottom of the stirring screw extends into the bottom of the conveying channel 5, so that the stirring screw stirs and mixes the original soil and the amendment.

[0040] The automatic soil amendment device provided by the embodiment of the application can stir and mix the amendment and the original soil on the ground, does not occupy the limited space on the vehicle body 1, and saves the energy consumption of conveying the soil to the vehicle body 1.

[0042] Further, the resistance-reducing opening 8 gradually widens in the advancing direction of the vehicle body 1, which means that the resistance-reducing opening 8 gradually widens from the rear to the front of the vehicle body 1, that is, the width of the front side of the resistance-reducing opening 8 is greater than that of the rear side, and that the cylinder body 4 is floatingly connected to the vehicle body 1, which means that the cylinder body 4 can move relative to the vehicle body 1, such as being swingably or telescopically connected to the vehicle body 1, which brings another effect that when a hard object such as a stone abuts against the lower side of the cylinder body 4, the hard object can be avoided by the resistance-reducing opening 8 to some extent, and if the resistance-reducing opening 8 cannot avoid the hard object, the hard object can be avoided by the swing or upward movement of the cylinder body 4.

[0047] Further, the vertical middle part of the conveying channel 5 is provided with a partition plate 10, that is, the partition plate 10 divides the conveying channel 5 into two parts of upper part and lower part, the conveying cylinder 6 passes through the partition plate 10, and only the lower part leaks out the conveying screw, so that two effects are brought, one is that the partition plate 10 strengthens the cylinder body 4, and the other is that the partition plate 10 divides the in-situ soil into two parts of upper layer and lower layer, and the amendment is conveyed to the in-situ soil of the lower layer through the conveying cylinder 6, thereby reducing the risk that the amendment of the surface layer is lost by wind and rain.

[0048] Further, as shown in Figures 8-11 , the conveying cylinder 6 is vertically movably connected to the cylinder body 4, for example, the top of the cylinder body 4 has a vertical hole, the conveying cylinder 6 is movably connected to the vertical hole, the outer wall of the conveying cylinder 6 is provided with a radial protruding part to lap the part of the cylinder body 4 provided with the vertical hole, the partition plate 10 is fixedly connected to the conveying cylinder 6, the two ends of the partition plate 10 have a first gap with the inner wall of the cylinder body 4, the cylinder body 4 comprises two oppositely arranged arc-shaped plates, the bottom of the two arc-shaped plates has a resistance-reducing opening 8, the top of the two arc-shaped plates is rotatably connected to a vertical telescopic column 13, and further comprises a spring mechanism for maintaining the position of the two arc-shaped plates, for example, a spring is pressed between the top of the two arc-shaped plates, or a torsional spring is sleeved on the rotating shaft of the arc-shaped plate, at the same time, the vehicle body 1 has two limiting columns 11, the two limiting columns 11 are matched with the two arc-shaped plates respectively, the end of the limiting column 11 is arranged in the rotating stroke of the arc-shaped plate, but the second gap is arranged between the end of the limiting column 11 and the outer wall of the arc-shaped plate, preferably, the limiting column 11 is arranged in parallel with the vertical telescopic column 13, at the same time, the whole structure is swingably connected to the vehicle body 1, that is, the vehicle body 1 is swingably connected to a connecting frame 12, the vertical telescopic column 13 and the limiting column 11 are connected to the connecting frame 12, and the conveying cylinder 6 is movably connected to the connecting frame 12, so that the advantages are that the different sizes of hard objects can be passively adapted, when the hard object is small, at this time, for example, Figure 9As shown, when it enters the resistance-reducing opening 8, it directly pushes away the two arc-shaped plates or moves up the integral driving cylinder body 4 to achieve avoidance, at which time the rotation amplitude of the arc-shaped plates is limited within the second gap, that is, it will not hit the limiting column 11, and when the hard object is larger, at this time, if Figure 10 As shown, when it enters the resistance-reducing opening 8, it directly pushes away the two arc-shaped plates or moves up the integral driving cylinder body 4 to achieve avoidance, at which time the rotation amplitude of the arc-shaped plates is limited within the second gap, that is, it will not hit the limiting column 11, and when the hard object is larger, at this time, if

[0049] In still another embodiment of the present application, the stirring member 7 is located outside the discharge port of the cylinder body 4, and the stirring radius of the stirring member 7 is greater than the radial dimension of the cylinder body 4. At this time, the stirring member 7 is located behind the cylinder body 4, which provides a larger stirring range. The stirring members 7 in the foregoing two embodiments are located in the conveying channel 5, so they can only stir part of the in-situ soil. For example, the diameter of the cylinder body 4 is 30 cm, but the distance between each cylinder body 4 is 20 cm, so the space between each cylinder body 4 cannot be mixed. However, by setting the stirring member 7 to the rear side of the cylinder body 4, a larger range of mixing can be stirred, for example, the radial dimension of the stirring member 7 can be set to be greater than 30 cm, such as 40 cm or even more.

[0050] In still another embodiment of the present application, the inner wall of the cylinder body 4 is provided with spiral-shaped raised rib plates, which can strengthen the strength of the cylinder body 4 and make the in-situ soil rotate in a local spiral in the cylinder body 4, thereby improving the mixing effect of the in-situ soil and the improving agent in the cylinder body 4.

[0051] The foregoing merely illustrates some exemplary embodiments of the application, and no doubt numerous modifications and alterations thereto will be apparent to those skilled in the art. Accordingly, the above description is intended for purposes of illustration only and should not be construed as limiting the scope of the application.
