When the soil conveying device 300 moves to a suitable position, the position of the soil conveying device 300 is fixed through a locking member of the moving wheel set, keeping the working state stable.

[0039] Considering that the soil material can be compacted into blocks in the soil hopper 100 or the soil material itself has relatively large soil blocks, in some embodiments, the soil conveying device 300 is connected with a soil screening device 200, the soil screening device 200 includes a soil screening outlet 231 and a soil screening inlet 232, the soil screening inlet 232 corresponds to the position of the soil discharge port 110, and the soil screening outlet 231 is arranged corresponding to the input end of the soil conveying device 300. The soil screening device 200 can screen the soil material discharged from the soil hopper 100, so that the soil material meeting the requirements of seedling raising falls into the soil conveying device 300 and is conveyed to a designated component or station, and the soil blocks with relatively large particles are screened and intercepted, improving the quality of seedling soil. In addition, the soil screening device 200 is connected with the soil conveying device 300, and the soil screening device 200 can move together with the soil conveying device 300 and can switch between different installation positions.

[0040] Further, as Figure 4 and Figure 6As shown, the soil screening device 200 comprises a soil screening support 210, a drum screening body 220 and a soil screening shell 230. The soil screening shell 230 is connected with the soil screening support 210, the drum screening body 220 is rotatably arranged on the soil screening support 210, the drum screening body 220 is located inside the soil screening shell 230, and the soil screening shell 230 is provided with a soil screening outlet 231 on the side facing the soil conveying device 300. The soil screening shell 230 can wrap the circumferential side of the drum screening body 220, preventing the soil material from splashing outside the soil screening device 220 when the drum screening body 220 is rotating, and reducing dust dispersion. The drum screening body 220 is connected with a first driving member 250, and the first driving member 250 drives the drum screening body 220 to rotate along the axial direction thereof. It should be noted that the soil conveying device 300 is arranged obliquely and conveys the soil material from bottom to top, and the soil screening inlet 232 of the soil screening device 200 is located at the higher end, so that the soil material can enter the drum screening body 220 under the action of gravity. It should be noted that the first driving member 250 is a motor.

[0041] In some embodiments, as shown in Figure 4 and Figure 7 The drum screening body 220 is provided with an agitating rod set 240 inside, and the agitating rod set 240 is coaxially arranged with the drum screening body 220. The rotation circumference of the agitating rod set 240 is concentric with the rotation circumference of the drum screening body 220, which can improve the agitating efficiency of the soil material and prevent the soil material from being hardened in the drum screening body 220 and causing the screen hole of the drum screening body 220 to be blocked.

The stirring long rod 243 is arranged along the central axis length direction of the drum screen body 220, which increases the stirring range of the entire stirring rod group 240 and makes the stirring of the soil more sufficient. The stirring disc 241 is installed on the rotating shaft 270, and the rotating shaft 270 is connected with the second driving member 260. It should be noted that the second driving member 260 is a servo motor, and the steering direction thereof can be controlled by servo control.

[0043] In some embodiments, as shown in Figure 6 and Figure 8 As shown, the drum screen body 220 is provided with a chain tooth at the outer ring of one end of the soil screening inlet 232, and a plurality of guide wheels 211 are correspondingly arranged at the inner ring. The first driving member 250 is connected with the chain tooth through a chain. It can be understood that the output end of the first driving member 250 is connected with a driving sprocket, and the driving sprocket is connected with the chain tooth through a chain. The rotation of the first driving member 250 drives the entire drum screen body 220 to rotate, thereby rolling and screening the soil in the drum screen body 220. Further, in order to enable the soil to enter the drum screen body 220, the plurality of guide wheels 211 are distributed in the circumferential direction of the inner ring, and the wheel surface of the guide wheel 211 is arranged to fit the inner ring. The guide wheel 211 is rotatably installed on the soil screening support 210. The circumferentially distributed guide wheels 211 can minimize the space occupied by the soil screening inlet 232, reduce the shielding of the position of the soil screening inlet 232, and improve the soil feeding efficiency. Specifically, referring to Figure 8 , the guide wheel 211 is installed on the soil screening support 210 through a guide plate 212, and the guide wheel 211 is rotatably connected with the guide plate 212. The end of the drum screen body 220 relative to the soil screening inlet 232 is rotatably connected with the soil screening support 210 through the rotating shaft 270, and the end relative to the soil screening inlet 232 is located at a lower position. The outer side of the end is shielded by the soil screening shell 230 to prevent the soil from leaking out.

[0044] In some embodiments, as shown in Figure 4 and Figure 5As shown, the soil conveying device 300 comprises a conveying frame 310 and a conveying belt 320, the conveying belt 320 is installed on the conveying frame 310 and is driven by a third driving member 330; the conveying belt 320 is provided with wavy retaining edges 322 on both sides, and a plurality of transverse partitions 321 are arranged on the conveying surface of the conveying belt 320, and the both ends of the transverse partitions 321 are connected with the wave crests of the wavy retaining edges 322 on both sides. The wavy retaining edges 322 play a role in preventing the material from sliding and falling, and the wavy retaining edges 322 are designed in a corrugated shape to facilitate the bypassing of the roller. The transverse partitions 321 function to support the material, and in order to realize large-angle conveying, it is especially suitable for conveying powdery, granular, small block-shaped, paste-shaped and liquid-shaped materials that are easy to fall off.
