[0024] Embodiment 1

[0025] Referring to Figure 1 and Figure 2 as shown, a plastic film laying device for vegetable planting of the present utility model: includes a film laying vehicle,

[0026] The film laying vehicle includes an adjustment mechanism 1, a plurality of support legs 2, a support assembly 3 and two support rods 4. The adjustment mechanism 1 includes a first adjustment plate 101, a second adjustment plate 102 and a third adjustment plate 103. Drag hooks 7 are provided at the rear ends of the first adjustment plate 101 and the third adjustment plate 103 for guiding the laying of the plastic film. The second adjustment plate 102 is placed between the first adjustment plate 101 and the third adjustment plate 103 and is movably connected;

[0027] Among them, a plurality of support legs 2 are all fixed on the lower surface of the support plate, and rollers 201 are movably connected to the lower ends of the plurality of support legs 2;

[0028] In addition, support plates are provided on the outer sides of the first adjusting plate 101 and the third adjusting plate 103. The two support assemblies 3 include a first vertical rod 301, a second vertical rod 302, a cross bar 303 and a push rod 304. The two first vertical rods 301 and the second vertical rods 302 are both fixed on the upper surface of the support plate. The cross bar 303 is arranged between the first vertical rod 301 and the second vertical rod 302. The push rod 304 is fixed on one side of the cross bar 303. The push rod 304 is used to push the film laying vehicle, or is connected to other equipment here to drive it to perform film laying operations;

[0029] Two fixing holes 401 are provided on the inner sides of the first adjusting plate 101 and the third adjusting plate 103. Threads are provided in the fixing holes 401 for fixing the support rods 4. The fixing holes 401 are both movably connected to the two support rods 4. The two support rods 4 are symmetrically arranged, and the other ends are not fixed. Thus, the two support rods 4 can cooperate to extend here, so as to achieve the unity of adjusting the width of the film laying vehicle.

[0030] Embodiment 2

[0031] Since the existing plastic films cannot be adjusted in width according to the actual situation of vegetable planting during laying;

[0032] Based on the above problems, referring to Figure 3 and Figure 4 As shown, chutes 5 are provided on the inner sides of the first adjusting plate 101 and the third adjusting plate 103 for the second adjusting plate 102 to move left and right inside to adjust the distance between the first adjusting plate 101 and the third adjusting plate 103. Openings are provided on the front surfaces of the first adjusting plate 101 and the third adjusting plate 103. Fixing members 6 are provided in the openings for adjusting the positions of the first adjusting plate 101 and the third adjusting plate 103 and the second adjusting plate 102. Grooves 10201 are provided on the front surfaces of the first adjusting plate 101 and the third adjusting plate 103;

[0033] Specifically, sliding rods 601 are provided at the rear ends of the two fixing members 6, and are both movably connected to the openings. Connecting rods 602 are provided at the rear ends of the two sliding rods 601. Limit heads 603 are provided at the rear ends of the connecting rods 602. The limit heads 603 pass through the openings and penetrate through the chutes 5 to be connected to the grooves 10201 of the first adjusting plate 101 and the second adjusting plate 102. Threads are provided on the surfaces of the two limit heads 603 and the connecting rods 602.

[0034] Working principle: When it is necessary to lay the film, first check whether the film laying vehicle needs to be adjusted according to the current vegetable planting situation. If adjustment is required, the fixing member 6 can be loosened respectively, so that the limiting head 603 at the end of the connecting rod 602 of the fixing member 6 is removed from the groove 10201 of the current adjusting plate two 102. Subsequently, the distance between the adjusting plate one 101 and the adjusting plate three 103 is adjusted by moving the cross bar 303 towards the middle, so that the adjusting plate two 102 moves in the chute 5 on the inner sides of the adjusting plate one 101 and the adjusting plate three 103. Until the appropriate width is adjusted, at this time, the fixing member 6 also changes its position in the opening along with the position change of the adjusting plate two 102. Subsequently, tighten the fixing member 6 so that the limiting head 603 at its front end is screwed into the groove 10201 of the adjusting plate two 102 through the thread. And the thread provided in the connecting rod 602, as Figure 4 shown, is used to play a role in stabilizing the current position of the fixing member 6 to a certain extent. Subsequently, take out the plastic film and remove the two support rods 4, and make them pass through the inner diameter of the plastic film respectively. Subsequently, one end of each support rod 4 is inserted into the appropriate fixing hole 401 according to the height of the vegetables and fixed by the thread. After completion, the staff push the film laying vehicle forward through the push rods 304 on both sides, so that the beginning of the film is smoothed onto the two drag hooks 7, and the two sides of the film are lifted by the drag hooks 7 to complete the laying.
