DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The present utility model will be further described in detail below with reference to the accompanying drawings.

[0020] AsFigure 1 , Figure 2 As shown in Figure 2 , a soil excavation and extraction device includes a support base 1, a support rod 2, a soil extraction clamp 3, and a driving mechanism 4.

[0021] As Figure 1 , Figure 2 shown in Figure 1 , the support base 1 is used to be fixed on the seedling raising machine. A pair of support rods 2 are arranged in parallel, and the upper ends are rotatably connected to both sides of the lower end position of the support base 1.

[0022] As Figure 1 , Figure 2 shown in Figure 1 , the soil extraction clamp 3 is arranged at the lower end of the support rod 2. The soil extraction clamp 3 is arranged with a wider upper part and a narrower lower part, and is arranged in a conical tube shape after being buckled, so as to realize the clamping of the soil. A cutting edge 31 is arranged at the lower end of the soil extraction clamp 3, so that the soil extraction clamp 3 can easily penetrate into the ground. An installation ring 32 is arranged at the upper end of the soil extraction clamp 3, and the installation ring 32 is connected to the support rod 2 through bolts, so as to realize the separate repair and replacement and convenient repair and replacement of the soil extraction clamp 3 after damage.

[0023] As Figure 1 , Figure 2 shown in Figure 1 , the driving mechanism 4 is used to control the opening and closing of a pair of soil extraction clamps 3. The driving mechanism 4 includes a driving block 41, a driving rod 42, a guiding block 43, and a guiding rod 44.

[0024] As Figure 1 , Figure 2 shown in Figure 1 , the driving block 41 is vertically arranged between a pair of support rods 2. The driving rod 42 is vertically arranged at the upper end of the driving block 41, and the driving rod 42 vertically slides and penetrates through the support base 1. A pair of guiding blocks 43 are vertically arranged on the inner side walls of the support rods 2, and the driving block 41 clamps the outer wall of the guiding block 43.

[0025] As Figure 1 , Figure 2 shown in Figure 1 , the guiding rods 44 are horizontally arranged on both sides of the lower end position of the driving block 41. The guiding block 43 is provided with guiding holes 45 for the guiding rods 44 to penetrate and slide. The upper ends of the guiding holes 45 are far away from each other, and the lower ends are close to each other.

[0026] When soil excavation and extraction operations are required, first control the driving rod 42 to move downward. At this time, the driving rod 42 drives the driving block 41 and the guiding rods 44 to move synchronously, and under the cooperation of the guiding holes 45 on the guiding block 43, the lower ends of a pair of support rods 2 gradually turn outwards, and drive the soil extraction clamp 3 to move synchronously, realizing the opening and closing control of the soil extraction clamp 3.

[0027] Subsequently, the soil grabbing clamp 3 is stabbed into the ground, and then the driving rod 42 is controlled to move upward, so as to realize the closing control of a pair of soil grabbing clamps 3, clamp the soil in the soil grabbing clamps 3, and at the same time, a soil pit for placing the nutrient bowl is automatically formed on the ground, realizing the operations of digging a pit and grabbing soil at one time.

[0028] Therefore, by setting the cooperation between the rotary support rod 2 and the soil grabbing clamp 3, the soil grabbing clamp 3 can be stabbed into the ground, and the soil grabbing clamp 3 can be controlled to close under the ground, automatically dig a soil pit on the ground, and after the pit digging is completed, the soil is automatically stored in the soil grabbing clamp 3, realizing the operations of digging a pit and grabbing soil, replacing the traditional manual operation, so as to achieve the effect of facilitating pit digging and soil grabbing.

[0029] Such as Figure 1 、 Figure 2 As shown in the figure, the support base 1 includes a bearing seat 11, a rotating rod 12, a seat plate 13 and a rotating mechanism 14. The bearing seat 11 is used to be fixed on the seedling raising machine, the rotating rod 12 vertically penetrates and is rotatably connected to the bearing seat 11, and the seat plate 13 is horizontally arranged at the lower end of the rotating rod 12.

[0030] Such as Figure 1 、 Figure 2 As shown in the figure, the rotating mechanism 14 is used to control the reciprocating rotation of the rotating rod 12. The rotating mechanism 14 includes a rotating gear 15 and a rotating rack 16. The rotating gear 15 is arranged on the outer wall of the upper end of the rotating rod 12, and the rotating rack 16 is horizontally slidably connected to the seedling raising machine and meshes with the rotating gear 15. In the actual use process, the rotating mechanism 14 can also adopt various driving methods such as the cooperation of a sprocket and a chain, and the cooperation of a synchronous belt and a pulley.

[0031] When the operations of digging a pit and grabbing soil are required, when the soil grabbing clamp 3 is stabbed into the ground, the rotating rack 16 is controlled to horizontally slide. At this time, the rotating rack 16 drives the rotating gear 15 and the rotating rod 12 to rotate synchronously, and drives the seat plate 13 and the soil grabbing clamp 3 to rotate synchronously. At this time, the soil grabbing clamp 3 can stably rotate out a soil pit on the ground.

[0032] At the same time, after the soil grabbing clamp 3 grabs the soil, the direction of the soil grabbing clamp 3 is controlled to rotate, so that the soil in the soil grabbing clamp 3 is separated from the ground, realizing stable pit digging and soil grabbing operations. At the same time, when the soil grabbing clamp 3 is lifted, the friction between the soil grabbing clamp 3 and the soil can be reduced, making the soil grabbing process more convenient.

[0033] The specific embodiments are only explanations of the present invention, and they are not limitations on the present invention. Those skilled in the art can make modifications without creative contributions to the embodiments according to needs after reading this specification, but as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
