It is used to cover the ground to increase soil temperature, retain soil moisture, maintain soil structure, prevent pests from attacking crops and diseases caused by certain microorganisms, etc., and promote plant growth.

[0003] During agricultural work, ground film is often used to protect crops. Because the ground film is easily scratched and damaged, it is often equipped with a storage box when used. The traditional storage box only has the function of storage. When the ground film reaches a certain length, it needs to be cut off. At this time, the operator needs to use a knife or other tools to cut the ground film. The tools need to be carried with them, which is very inconvenient. At the same time, when the ground film is cut, the surface is rough and broken. Summary of the invention

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] The utility model provides Figures 1 to 5 A storage box with a ground film cutting function is shown, comprising:

[0025] A storage box 1, wherein a ground film roll 2 is placed in an inner cavity of the storage box 1;

[0026] A T-shaped plate 3 is fixed to the front end of the storage box 1, and a limiting groove 4 is horizontally provided on the top of the T-shaped plate 3. The inner cavity of the limiting groove 4 is slidably connected to a limiting block 5, which extends upward to the top of the T-shaped plate 3. Cutting knives 6 are staggered up and down on both sides of the limiting block 5. A sliding rod 7 is fixed to the top of the storage box 1. An operating rod 8 is slidably connected to the surface of the sliding rod 7. A through groove is provided at the end of the operating rod 8 away from the sliding rod 7. A connecting rod 9 is fixed to the top of the limiting block 5. The top of the connecting rod 9 passes through the through groove and extends upward. Two sets of limiting wheels 10 are installed on the surface of the limiting block 5 through a mounting frame. The limiting wheels 10 are attached to the top of the T-shaped plate 3 and are located at the front and rear sides of the limiting groove 4.

[0027] The limiting block 5 is translated by the operating rod 8 and the connecting rod 9 to drive the cutting knife 6 to slide from one side of the ground film to the other side to cut the ground film. When cutting, the ground film is limited by the limiting wheel 10 to ensure the flatness of the cutting position of the ground to prevent the cutting knife 6 from squeezing and pushing the ground film to one side. The cutting knife 6 can move in both directions for cutting, which is convenient and quick, and can ensure that the cutting edge is smooth and neat.

[0028] A protective cover 11 is hinged on the back of the storage box 1 through a hinge, and two sets of movable plates 12 are slidably set on both sides of the inner cavity of the storage box 1. The back of the movable plate 12 is rotatably connected with a mounting plate 13 through a movable shaft, and a limiting seat 14 for limiting the ground film roll 2 is fixed on the opposite side of the mounting plate 13. Through the design of the protective cover 11, it is convenient for the ground film roll 2 to enter and exit the storage box 1, and then the limiting seat 14 is installed by using the movable plate 12 and the mounting plate 13, so that the mounting plate 13 can slide out of the storage box 1 and unfold on the outside of the storage box 1 to clamp and install the ground film roll 2.

[0029] A fixing block 15 is fixed to the top of the connecting rod 9, and a supporting spring 16 is sleeved on the outer side of the connecting rod 9. One end of the supporting spring 16 is fixed to the bottom of the fixing block 15, and the other end of the supporting spring 16 is fitted to the top of the operating rod 8. Two groups of oblique blocks 17 for limiting the operating rod 8 are fixed to the top of the storage box 1. The supporting spring 16 is supported by the limiting block 5 so that the supporting spring 16 squeezes the operating rod 8 to deflect downward, and cooperates with the oblique block 17 to limit the position of the operating rod 8 to prevent the limiting block 5 from sliding in the limiting groove 4 when releasing the ground film, causing the cutting knife 6 to scratch the ground film.

[0030] Slide grooves 18 are provided on both sides of the top and bottom of the inner cavity of the storage box 1, and the top and bottom of the movable plate 12 extend to the inner cavity of the slide groove 18. Through the setting of the slide groove 18, it is convenient to limit the movable plate 12 and at the same time limit the movable plate 12 from sliding out of the storage box 1, so as to facilitate the storage and installation of the ground film roll 2.

[0031] A through groove 19 is provided on one side of the storage box 1 close to the T-shaped plate 3. The inner cavity of the through groove 19 is rotatably connected to two sets of mutually fitting limiting rollers 20 through bearings. The setting of the limiting rollers 20 facilitates the clamping and transportation of the ground film, ensuring that the ground film remains flat when released.

[0032] A pawl 21 is installed in the inner cavity of the through groove 19, and a ratchet 22 is fixed on the surface of the limiting roller 20. The pawl 21 is located on the outside of the ratchet 22 and meshes with the ratchet 22. The setting of the ratchet 22 and the pawl 21 facilitates the rotation limit of the limiting roller 20. The limiting roller 20 can be used to transport the ground film smoothly. After the ground film is cut, the limiting roller 20 can be prevented from rotating in the opposite direction and retracted into the storage box 1.

[0033] A guide roller 23 is installed on the side of the T-shaped plate 3 away from the storage box 1, and a rubber pad is bonded to the top of the T-shaped plate 3. Through the design of the guide roller 23, the smooth surface of the guide roller 23 is used to facilitate the turning of the ground film to prevent the edge of the T-shaped plate 3 from scratching the ground film. At the same time, the setting of the rubber pad can improve the adhesion ability of the ground film.

[0034] When in use, open the protective cover 11, move the mounting plate 13 outward, and at the same time, the mounting plate 13 drives the movable plate 12 to slide in the slide groove 18, so that the ground film roll 2 is stuck on the mounting seat, and then the movable plate 12 and the mounting plate 13 are moved back into the storage box 1, and the protective cover 11 is closed. The ground film led out from the ground film roll 2 passes through the two sets of limiting rollers 20 in the through groove 19. The pulled ground film can extend the length of the ground film. When it is necessary to cut the ground film, move the operating rod 8 upward so that the operating rod 8 passes over the oblique stopper 17, and then slides to the other side on the slide rod 7. The operating rod 8 drives the connecting rod 9 and the limiting block 5 to move horizontally. During the movement, the limiting wheel 10 limits the ground film so that the ground film fits on the top of the T-shaped plate 3, and the limiting block 5 drives the cutting knife 6 to cut the ground film. After moving to the other side, the operating rod 8 passes over the oblique stopper 17 and is limited to prevent the limiting block 5 from shaking.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
