An inclined plate is fixedly connected inside the connecting frame, and two support legs are fixedly connected to the bottom left end of the inclined plate. A connecting shaft is fixedly connected to the middle of the connecting rods, and a connecting ring is movably connected to the outer surface of the connecting shaft. A short rod is fixedly connected to the outer surface of the connecting ring. A collection box is snapped into the right side of the connecting frame, and a connecting box is fixedly connected to the top of the connecting frame. A motor is fixedly connected to the left side of the connecting box, and a coupling is fixedly connected to the outer surface of the motor's main shaft. A stirring rod is fixedly connected to the inner surface of the coupling. This invention, by setting a connecting box, motor, coupling, stirring rod, blade, connecting hole, and filter screen on the connecting frame, can break up large clods of soil, improving soil utilization.

[0004] The aforementioned patent has the following problems: The patent has some drawbacks in its use, such as: when the device is in use, there is a certain gap between each blade, which will cause some soil clods to not be broken. Also, when the device is feeding, the soil will fall directly onto the filter screen. If too much soil accumulates, it will not be able to leak out of the filter screen. Therefore, a seed cultivation soil screening device is proposed. Utility Model Content

[0022] like Figures 1 to 4 As shown, a seed cultivation soil screening device includes a workbench 1. Two hydraulic cylinders 4 are fixedly installed on the top of the workbench 1. Connecting plates 5 are fixedly installed on the output ends of the two hydraulic cylinders 4. A storage box 2 is fixedly installed between the two connecting plates 5. The storage box 2 has an inner cavity 9 and a discharge trough 15. An auger 10 is rotatably installed in the inner cavity 9. A drive assembly for driving the auger 10 to rotate is provided on the storage box 2. A rotating shaft 11 is fixedly installed at one end of the auger 10 and located in the discharge trough 15. Several first crushing rods 12 are fixedly installed on the rotating shaft 11. Several third crushing rods 16 are fixedly installed on the inner wall of the discharge trough 15. Figure 2 As shown, the drive assembly includes a drive motor 3, which is fixedly mounted on the top of the storage box 2. The output end of the drive motor 3 extends through the top of the storage box 2 into the inner cavity 9 and is coaxially connected to the auger 10. The output shaft of the drive motor 3 is rotatably connected to the storage box 2.

[0023] More specifically, during use, the staff puts the soil to be screened into the inner cavity 9 through the feed port on the storage box 2. Under the action of the auger 10, the soil will not fall down. When the inner cavity 9 is full of soil to be screened, the drive motor 3 is connected to the power supply and started. The output shaft of the drive motor 3 will drive the auger 10 to rotate quickly. At this time, the auger 10 will transport the soil in the inner cavity 9 to the discharge trough 15. At the same time, the auger 10 will drive the rotating shaft 11 to rotate quickly. The rotating shaft 11 will drive several first crushing rods 12 to rotate quickly. With the cooperation of several third crushing rods 16, it is ensured that the clumps of soil entering the discharge trough 15 can be completely crushed.

[0024] like Figure 2 As shown, the lower end of the auger 10 is located inside the discharge trough 15, and the auger 10 is in contact with the inner wall of the discharge trough 15.

[0025] More specifically, it ensures that the auger 10 can block the soil in the inner cavity 9, and that the soil in the inner cavity 9 will not fall into the discharge chute 15 while the auger 10 remains stationary.

[0026] like Figure 2 and Figure 3As shown, the positions of several first crushing rods 12 are staggered from the positions of several third crushing rods 16.

[0027] More specifically, this ensures that soil clods can be broken up more effectively, preventing some clods from becoming unbreakable.

[0028] like Figure 1 As shown, the two hydraulic cylinders 4 are electrically connected, and the connecting plate 5 and the storage box 2 are integrally formed.

[0029] More specifically, this ensures that the two hydraulic cylinders 4 can operate simultaneously, thereby enabling the two connecting plates 5 to drive the storage box 2 to move up and down more stably. Example 2:

[0030] like Figure 1 and Figure 4 As shown, a through groove 17 is provided on the workbench 1, an annular frame 7 is provided in the through groove 17, a filter plate 8 is fixedly installed in the annular frame 7, a rotating plate 13 is fixedly installed at one end of the rotating shaft 11 and located in the annular frame 7, and several second crushing rods 14 are fixedly installed at the bottom of the rotating plate 13.

[0031] More specifically, the crushed soil will fall onto the filter plate 8 inside the annular frame 7. Some of the crushed soil will fall through the filter plate 8 into the collection box placed below the workbench 1. At the same time, the rotating shaft 11 will drive the rotating plate 13 to rotate, and the rotating plate 13 will drive several second crushing rods 14 to rotate, preventing impurities and small stones from accumulating together, avoiding affecting the screening, and also better crushing the soil, making it easier for the soil to pass through the filter plate 8 and fall into the collection box.

[0032] like Figure 1 and Figure 4 As shown, a pin 6 is inserted and installed inside the annular frame 7. One end of the pin 6 extends into the worktable 1, and the pin 6 is inserted and engaged with the worktable 1.

[0033] More specifically, this ensures that the pin 6 can be inserted into the annular frame 7 and the worktable 1, thereby ensuring the stability of the annular frame 7.

[0034] like Figure 4 As shown, the annular frame 7 and the through slot 17 are engaged.

[0035] More specifically, this ensures that the annular frame 7 can be inserted into the through slot 17, thereby ensuring the stability of the annular frame 7.

[0036] In summary: During use, the operator places the soil to be screened into the inner cavity 9 through the feed inlet on the storage box 2. Under the action of the auger 10, the soil will not fall downwards. When the inner cavity 9 is full of soil to be screened, the drive motor 3 is powered on and started. The output shaft of the drive motor 3 will drive the auger 10 to rotate rapidly. At this time, the auger 10 will transport the soil in the inner cavity 9 to the discharge chute 15. Simultaneously, the auger 10 will drive the rotating shaft 11 to rotate rapidly, which will drive several first crushing rods 12 to rotate rapidly, in conjunction with several third crushing rods 1... With the cooperation of 6, the clumps of soil entering the discharge trough 15 are completely crushed. Then, the crushed soil will fall onto the filter plate 8 in the annular frame 7. Some of the crushed soil will fall into the collection box placed below the workbench 1 after passing through the filter plate 8. At the same time, the rotating shaft 11 will drive the rotating plate 13 to rotate, and the rotating plate 13 will drive several second crushing rods 14 to rotate, preventing impurities and small stones from accumulating together, avoiding affecting the screening, and also better crushing the soil, making it easier for the soil to pass through the filter plate 8 and fall into the collection box. When the soil screening is complete and the impurities and small stones in the annular frame 7 need to be cleaned, the workers can connect the two hydraulic cylinders 4 with their wires and start them. The output shafts of the two hydraulic cylinders 4 will extend simultaneously and drive the two connecting plates 5 to move upward at the same time. The two connecting plates 5 will drive the storage box 2 to move upward, thereby causing the rotating plate 13 and several second crushing rods 14 to move above the annular frame 7. Then the workers can pull the pin 6 upward to remove the pin 6 from the workbench 1 and the annular frame 7. Then the annular frame 7 can be removed from the through groove 17.
