Description

Technical Field

[0001] The utility model belongs to the technical field of plastic film mulching, and specifically relates to an artificial film mulching device. Background Art

[0002] Plastic film can not only increase soil temperature, conserve water, soil and fertilizer, improve fertilizer efficiency, but also has multiple functions such as weed control, pest and disease prevention, drought and waterlogging resistance, salt inhibition and seedling protection, improving the near-surface light and heat conditions, and making the products hygienically clean. For newly emerged seedlings, it has the effects of protecting roots and promoting growth. Therefore, plastic film has been widely used in agricultural production.

[0003] After retrieval, a document with the publication number (CN220528785U) discloses a plastic film mulching auxiliary device. The support mechanism includes a sliding groove seat, a plastic film fixing frame and a conical fixing seat. The sliding groove seat is fixedly connected to the front end of the connecting push rod. Two plastic film fixing frames are symmetrically and movably arranged on both sides of the sliding groove seat. Two conical fixing seats are symmetrically rotatably connected to the front ends of the two plastic film fixing frames. The auxiliary device connects and fixes the plastic film roll through the support mechanism, and uses the conical fixing seats on both sides of the plastic film fixing frame to rotatably support the plastic film roll.

[0004] However, in daily use of this device, it is impossible to compact and cover both sides of the film while laying the film. After film mulching, it is necessary to cover the soil on both sides of the film manually, which increases the operation steps of workers and reduces the film mulching efficiency.

[0005] In view of this, the present utility model is specifically proposed. Summary of the Utility Model

During adjustment, loosen the bolt 15 on the upper part of the adjusting rod 2, and then adjust the telescopic length of the adjusting rod 2 by sliding and pulling. Use the clamping posts 18 on both sides of the adjusting rod 2 to clamp and fix the film roll. Then tighten the bolt 15 with the relative positioning hole 16 to complete the locking and fixing of the adjusting rod 2. Then place the film roll on the upper part of the ridge, and fix the end of the film on the upper part of the ridge. When laying the film, the elastic member 19 in the bead pressing device 17 pushes the contact rod 20 downward, and the contact rod 20 squeezes both sides of the film downward. At the same time, the soil covering wheel 4 drives the soil on both sides of the ridge inward and presses it on both sides of the film, avoiding the need for manual secondary soil covering operation on both sides of the film, improving work efficiency, and pressing down the support rod 3 through the counterweight of the counterweight groove 5 to make the soil covering wheel 4 closely contact the ridge. At the same time, with the help of the moving wheel 6 abutting against the ground and rotating, a certain supporting force is provided for the device, thereby reducing the burden of manually pulling the device and improving work efficiency.

[0028] Specifically, the whole soil covering wheel 4 is in an arc shape. A plurality of openings are formed on the soil covering wheel 4. Intermittent soil covering is carried out through the openings on the soil covering wheel 4. The soil covering wheel 4 is in an inclined state, and the inclined direction of the soil covering wheel 4 faces the adjusting rod 2. Intermittent soil covering is carried out through the openings on the soil covering wheel 4 to provide growth space for the seed roots on both sides of the film, avoiding continuous compaction and covering, resulting in no growth space for the seed roots, and improving the practicality of the device.

[0029] Specifically, the bead pressing device 17 forms a cylindrical structure. An elastic member 19 is movably installed in the bead pressing device 17. One end of the elastic member 19 abuts against a contact rod 20. The contact rod 20 is slidably connected with the bead pressing device 17. The other end of the contact rod 20 is in an arc shape. The elastic member 19 is a spring. The elastic member 19 in the bead pressing device 17 pushes the contact rod 20 downward, and the contact rod 20 squeezes both sides of the film downward.

[0030] Specifically, a plurality of positioning holes 16 are formed on the adjusting rod 2. A bolt 15 is threadedly connected to the base 1. The bolt 15 is threadedly connected with the positioning hole 16. Loosen the bolt 15 on the upper part of the adjusting rod 2, and then adjust the telescopic length of the adjusting rod 2 by sliding and pulling. Use the clamping posts 18 on both sides of the adjusting rod 2 to clamp and fix the film roll. Then tighten the bolt 15 with the relative positioning hole 16 to complete the locking and fixing of the adjusting rod 2.

[0031] Specifically, a handle 7 is fixedly connected to the upper end of the base 1. Connecting blocks 8 are symmetrically arranged on the handle 7, and the connecting blocks 8 are fixedly connected to the handle 7. A bracket 9 is pivotally connected between the two connecting blocks 8, and the device is supported and placed on the ground by the bracket 9 abutting against the ground.

A snap block 13 is fixedly connected to the other end of the pull rod 12. The return spring 14 pulls the pull rod 12 downward through its own elastic characteristic, and the pull rod 12 pushes the snap block 13 downward. Through the downward pushing force of the snap block 13, the plastic film roll is limited and locked to prevent the plastic film roll from rotating when the device moves.

Clamp and fix the plastic film roll with the clamping posts 18 on both sides of the adjusting rod 2. Then tighten the bolt 15 with the corresponding positioning hole 16 to complete the locking and fixing of the adjusting rod 2. Then place the plastic film roll on the upper part of the ridge, and fix the end of the plastic film on the upper part of the ridge.

At the same time, the soil covering wheel 4 drives the soil on both sides of the ridge inward and presses it on both sides of the plastic film, avoiding the need for manual secondary soil covering operation on both sides of the plastic film, improving the working efficiency. And the supporting rod 3 is pressed downward by the counterweight in the counterweight groove 5, so that the soil covering wheel 4 is in close contact with the ridge, and intermittent soil covering is carried out through the openings on the soil covering wheel 4 to provide a growth space for the seed roots on both sides of the film, avoiding continuous compaction and covering, resulting in no growth space for the seed roots, improving the practicability of the device. At the same time, with the help of the moving wheels 6 abutting against the ground and rotating, a certain supporting force is provided for the device, thereby reducing the burden of manually pulling the device and further improving the practicability of the device.
