[0023] The film assembly includes two support plates 7, the bottom ends of the two support plates 7 are fixed on the top of the mobile body 1, the two support plates 7 are both located in the box 5, and the tops of the support plates 7 are provided with U-shaped grooves 8. The film assembly also includes a film roller 9, and both ends of the film roller 9 are fixed with limit plates 10. The two ends of the film roller 9 rotate in the two U-shaped grooves 8 respectively. The surface of the limit plate 10 fits with the surface of the support plate 7, so that the film roller 9 can rotate stably on the support plate 7 and is convenient for taking and placing. A film 11 is wrapped around the surface of the film roller 9, and a first support seat 12 is fixed on the top of the mobile body 1. The top of the first support seat 12 The end is rotatably connected to the first guide roller 13, a second support seat 14 is fixed to the bottom of the mobile body 1, and the bottom end of the second support seat 14 is rotatably connected to the second guide roller 15. A strip hole 16 is opened in the middle of the mobile body 1, and the bottom end of the film 11 passes through the first guide roller 13, the strip hole 16 and the second guide roller 15 in sequence. Specifically, when the mobile body 1 moves, the bottom end of the film 11 covering the vegetables can be pulled, that is, the film roller 9 is rotated, thereby releasing the film 11, and under the guidance of the first guide roller 13, the strip hole 16 and the second guide roller 15, the film 11 is stably unfolded;

[0024] The pre-stressing assembly includes two vertically arranged cylinders 17, the bottom ends of the cylinders 17 are fixed to the top of the mobile body 1, and a return spring 18 is vertically fixed to the top of the inner wall of the cylinder 17. Two limiting holes 19 are provided on the mobile body 1, and the two limiting holes 19 are respectively connected to the two cylinders 17. A guide rod 20 is vertically passed through the limiting holes 19, and a connecting plate 21 is fixed to the top of the guide rod 20. The tops of the two connecting plates 21 are respectively fixedly connected to the bottom ends of the two return springs 18, and the bottom ends of the guide rods 20 are rotatably connected to rollers 22, and the two rolling wheels 22 are respectively in contact with the two side edges of the surface of the film 11. Specifically, when the mobile body 1 is moving, the rolling wheels 22 can press the two side edges of the surface of the film 11, and under the action of the return spring 18, the rolling wheels 22 can be kept rolling on the two side edges of the film 11 at all times;

[0025] The automatic film pressing assembly includes two vertically arranged connecting rods 23, the top ends of the two connecting rods 23 are fixed to the bottom of the mobile body 1, and the bottom ends of the two connecting rods 23 are fixed with plowboards 24.
