The pushing mechanism 7 is slidably connected to the inside of the cultivation vehicle 1. The pushing mechanism 7 is used to drive the connecting seat 3 to slide up and down along the inside of the seedling chamber 2. The pushing mechanism 7 includes several connecting columns 701 and a base 702. Several connecting columns 701 are evenly distributed inside the cultivation vehicle 1. The top of the connecting column 701 is fixedly connected to the bottom of the connecting seat 3, and the bottom end of the connecting column 701 is rotatably connected to the top of the base 702. Two cylinders 11 are symmetrically fixedly connected to the outside of the cultivation vehicle 1 on both sides. The output end of the cylinder 11 is fixedly connected to a connecting frame 12. Both ends of the connecting frame 12 are penetrated by the surface of the cultivation vehicle 1. One end of the connecting frame 12 penetrates into the interior of the cultivation vehicle 1 and is fixedly connected to the surface of the base 702. The base 702 is slidably connected to the interior of the cultivation vehicle 1 through the cylinder 11.

[0019] Among them, two cylinders 11 drive the connecting frame 12 to slide up and down on the surface of the cultivation vehicle 1, thereby driving the base 702 and the connecting seat 3 to slide up and down. In the process of the connecting seat 3 sliding downward in the seedling cavity 2, several scrapers 502 are located outside the receiving groove 9 and contact the inner wall of the seedling cavity 2.

[0027] The dirt flushed on the inner wall of the seedling raising chamber 2 is collected through the diversion chamber 22 and finally discharged through the guide hole 23, thereby preventing the dirt from remaining and affecting the effect of reuse.

[0028] The specific working principle and use method of the present invention are explained in detail below: when in use, the first step is to drive the connecting frame 12 to slide up and down on the surface of the cultivation vehicle 1 through the two cylinders 11, thereby driving the base 702 and the connecting seat 3 to slide up and down. In the process of the connecting seat 3 sliding downward in the seedling cavity 2, the scrapers 502 are located outside the receiving groove 9 and contact the inner wall of the seedling cavity 2. The sliding of the connecting seat 3 can scrape the inner wall of the seedling cavity 2 to prevent particles such as nutrient soil and root coverings from condensing and adhering to the inner wall of the seedling cavity 2, making it convenient to carry out cleaning work; In the second step, during the process of the connecting column 701 sliding up and down through the base 702, the transmission effect of the belt 13 forces the upper and lower guide wheels 802 to rotate synchronously, and the upper guide wheel 802 drives the rotating gear 803 to rotate through the meshing effect while rotating. Since the rotating gear 803 and the connecting column 701 can only slide up and down, the connecting column 701 and the connecting seat 3 are driven to rotate during the rotation of the rotating gear 803, and the connecting seat 3 drives the scraper 502 to slide circumferentially along the inner wall of the seedling chamber 2 during the rotation process, thereby ensuring the cleaning effect of the scraper 502 on the inner wall of the seedling chamber 2; In the third step, when the connecting seat 3 slides downward following the connecting column 701, the base 702 will squeeze the water bag 15 downward through the pressure plate 18. Through the action of pressure, the cleaning liquid in the water bag 15 is forced to be injected into the connecting cavity 602 through the conduit 16 and the connecting hole 17, and is transported to the flushing head 601 through the connecting groove 10, thereby completing the cleaning of the inner wall of the seedling cavity 2, and in conjunction with the rotation effect of the connecting seat 3, forcing the flushing head 601 to comprehensively flush the inner wall of the seedling cavity 2, and cooperating with the scraper 502 to complete the comprehensive cleaning of the seedling cavity 2.
