[0002] Film-laying seeders are mainly used for mulching farmland with plastic film and are an important symbol of modern, efficient, and high-yield agriculture. Existing film-laying seeders use a film-cutting and tape-cutting mechanism that uses a hydraulic cylinder to cut the plastic film and drip irrigation tape. This device only has the function of cutting the film and tape; it cannot cover the beginning and end points of each row with soil during sowing. Currently, manual soil covering of each row's beginning and end points is still required during sowing, increasing labor intensity and resulting in low sowing efficiency.

[0003] To achieve a simple structure and automatic soil covering, an automatic membrane and strip cutting soil covering device is proposed. Utility model content:

A push rod passes through the second bushing, and the two ends of the push rod are slidably connected to the first sliding groove.

[0008] Furthermore, a reinforcing rod is fixedly provided at the middle of the rear side of the two vertical support rods at an angle downwards, and the other ends of the two reinforcing rods are fixedly connected through the first crossbeam. An arc-shaped guide rod is fixedly provided on the vertical support rod above the opening, and the end of the arc-shaped guide rod away from the vertical support rod is fixedly connected to the reinforcing rod.

[0009] Furthermore, the clamping mechanism includes a crossbar and two connecting rods vertically fixed on the crossbar.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figure 1-6 As shown, this embodiment provides an automatic film cutting and strip cutting soil covering device, which includes a mounting frame 1, a film cutting component 2, a clamping mechanism 3, a pressing component 4 and a hydraulic cylinder 5, and the mounting frame 1 is fixedly connected to the seeder.

[0025] like Figure 3 As shown, the mounting frame 1 includes two symmetrically arranged vertical support rods 11. The tops of the two vertical support rods 11 are fixedly connected by a connecting rod. The two vertical support rods 11 are integrally formed with the connecting rod. The upper end of the mounting frame 1 is hinged to the fixed end of a hydraulic cylinder 5. The telescopic section of the hydraulic cylinder 5 is hinged to a film-cutting assembly 2 for cutting mulch film and drip irrigation tape. The hydraulic cylinder 5 and the film-cutting assembly 2 are located between the two vertical support rods 11. A clamping mechanism 3 is fixedly connected to the front of the film-cutting assembly 2. The clamping mechanism 3 is used to clamp the front of the film-cutting assembly 2. The plastic film and drip irrigation tape are arranged in a square shape. The film cutting assembly 2 is fixedly connected to the clamping mechanism 3 at the rear of the film cutting assembly 2, and is used to press the plastic film and drip irrigation tape at the rear of the film cutting assembly 2. The film cutting assembly 2 includes a U-shaped frame 21 and a film cutting knife 22. The film cutting knife 22 is fixed at the lower end of the U-shaped frame 21. The middle of the vertical rods on both sides of the U-shaped frame 21 is fixedly connected to a first bushing 22, and a rotating shaft 25 is inserted inside the first bushing 22. The upper end of the U-shaped frame 21 is fixedly provided with a second bushing 24, and a push rod 26 is inserted inside the second bushing 24.

[0026] like Figure 3-4 As shown, a first sliding groove 111 is formed on the inner sidewall of the middle part of the two vertical support rods 11. An opening 114 is formed at the bottom end of the first sliding groove 111 along the front of the vertical support rod 11. The inner bottom wall of the first sliding groove 111 is an arc-shaped surface 113 that extends to the opening 114. The two ends of the push rod 26 are slidably connected in the two first sliding grooves 111 respectively. A second sliding groove 112 is formed on the inner sidewall of the lower part of the two vertical support rods 11 respectively. The two ends of the rotating shaft 25 are slidably connected in the two second sliding grooves 112 respectively.

[0027] like Figure 5 As shown, the clamping mechanism 3 includes a crossbar 31 and two connecting rods 32 vertically fixed on the crossbar 31. A connecting part 33 is fixedly provided at the upper end of the two connecting rods 32 on opposite sides. The connecting part 33 includes a base 331 fixed to the connecting rod 32 and a limiting piece 332 fixed at both ends of the side of the base. A rotating shaft 25 is passed through the middle of the two limiting pieces 332 on the same base 331 and is rotatably connected to it. A rotating rod 34 is rotatably connected to the lower side of the crossbar 31 in the length direction. Several clamping pieces 341 are vertically fixed on the rotating rod 34 along the axial direction. A clamping block 342 corresponding to the clamping piece 341 is fixedly provided on the crossbar 31 above the clamping piece 341. Two driving members 35 are vertically fixed on the rotating rod 34.

[0028] Connecting seats 13 are fixedly installed at the bottom rear side of the two vertical support rods 11. Third sliding grooves 131 are formed on the opposite side walls of the two connecting seats 13, and the two connecting rods 32 are slidably connected within the two third sliding grooves 131. The sliding connection of the connecting rods 32 within the third sliding grooves 131 improves the stability of the clamping mechanism 3. Connecting blocks 132 are fixedly installed on the outer side walls of both connecting seats 13. A through hole is formed vertically on each connecting block 132, and a limiting rod 36 passes through the through hole. The bottom end of the limiting rod 36 is fixedly connected to the driving component 35, and a limiting block 361 is fixed above the limiting rod 36. Through the limiting rod 36, after the clamping mechanism 3 moves downward and clamps the mulch film and drip irrigation tape, its downward distance is limited, preventing breakage of the mulch film and drip irrigation tape.

[0029] like Figure 6 As shown, the pressing assembly 4 includes a pressing part 41 and a fixing part 42. One end of the fixing part 42 is fixed to the pressing part 41, and the other end is fixed with a fixing rod 43 that passes through two limiting pieces 332 on the same base 331. The bottom end of the fixing rod 43 is provided with a fixing nut 44.

[0030] A reinforcing rod 12 is fixedly installed at the middle of the rear side of the two vertical support rods 11 at an angle downwards. The other ends of the two reinforcing rods 12 are fixedly connected through the first crossbeam 17. An arc-shaped guide rod 14 is fixedly installed on the vertical support rod 11 above the opening 114. The end of the arc-shaped guide rod 14 away from the vertical support rod 11 is fixedly connected to the reinforcing rod 12.

[0031] In this embodiment, the hydraulic cylinder 5 drives the film-cutting assembly 2 to move downward. The film-cutting assembly 2 drives the clamping mechanism 3 and the pressing assembly 4 to move downward. The clamping mechanism 3 clamps the mulch film and drip irrigation tape in front of the film-cutting assembly 2, and the pressing assembly 4 presses down on the mulch film and drip irrigation tape behind the film-cutting assembly 2. The film-cutting blade 22 cuts the mulch film and drip irrigation tape under the action of the hydraulic cylinder 5 and penetrates a certain distance underground. Under the action of the arc surface 113, the film-cutting assembly 2 rotates backward with the push rod 26 above as the center, lifting the soil behind it, along with the mulch film and drip irrigation tape, backward and upward. Under the action of gravity, it falls onto the mulch film pressed by the pressing assembly 4, covering the mulch film behind the film-cutting assembly 2 with soil, thereby realizing the function of cutting the film and tape and automatically covering the soil at the end position of a row. When the seeder starts a new row, the seeder is lowered, and the mounting frame is lowered to the lowest point under the drive of the seeder. The film-cutting component is lifted upward by the hydraulic cylinder. Under the action of the arc-shaped guide rod, the film-cutting component pulls the soil in front of the film-cutting component forward with the push rod as the center, thus completing the covering of the film in front with soil. At this time, the utility model returns to the initial position.

[0032] In a preferred embodiment, a second crossbeam 15 and a third crossbeam 16 are respectively horizontally fixed at the middle and lower ends of the two vertical support rods 11. A balance bar 45 is vertically fixed on the fixing part 42, and the balance bar 45 passes through the second crossbeam 15 and is slidably connected to it. By having the balance bar 45 pass through the second crossbeam 15, the stability of the pressing assembly 4 pressing the mulch film and drip irrigation tape is increased.

[0033] Usage process:

[0034] When the seeder finishes planting a row, the hydraulic cylinder 5 is activated and moves downwards. The hydraulic cylinder 5 pushes the film-cutting assembly 2 downwards, which in turn drives the pressing assembly 4 and clamping mechanism 3 to move downwards as well. The film-cutting blade 22 cuts the mulch film and drip irrigation tape under the action of the hydraulic cylinder 5, penetrating a certain distance underground. The pressing part 41 of the pressing assembly 4 presses the mulch film and drip irrigation tape behind the film-cutting assembly 2, while the clamping mechanism 3 clamps the mulch film and drip irrigation tape in front of the film-cutting assembly 2. At this time, the hydraulic cylinder 5 continues to move downwards, and the push rod 26 slides out of the first groove 111 from the opening 114 under the action of the arc surface 113. The film-cutting assembly 2 rotates backwards with the rotating shaft 25 as the center, lifting the soil behind it, along with the mulch film and drip irrigation tape, upwards and backwards. Under the action of gravity, it falls onto the mulch film pressed by the pressing assembly 4, thus covering the mulch film behind it with soil. At this point, the tractor lifts the entire seeder and moves it to the starting point of another row. Then, it lowers the seeder and starts hydraulic cylinder 5 to lift it upwards. Under the action of hydraulic cylinder 5 and arc-shaped guide rod 14, the film-cutting assembly 2 rotates forward around the pivot 25, pulling the soil in front of the film-cutting blade 22 forward, thus completing the covering of the mulch film in front of the film-cutting assembly 2. Afterwards, hydraulic cylinder 5 lifts intermittently upwards until the entire device returns to its initial position.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
