Description

Technical Field

[0001] The utility model relates to the technical field of agricultural planting film covering, and more specifically, it relates to an agricultural planting film covering device. Background Art

[0002] Covering cultivation is an agricultural planting technology that improves the soil environment, retains heat and water, inhibits weed growth, reduces soil erosion and increases crop yields by covering the soil surface with a transparent plastic film. During use, the existing agricultural planting covering device can usually only install films of the same width. When the widths of the ridges to be covered are different and need to be covered with films of different widths, it is necessary to replace covering devices of different specifications, thereby reducing the versatility and practicality of the entire device and making it very inconvenient to use; secondly, the existing agricultural planting covering device usually does not have a cutting component during use. After a ridge is covered with film, it is necessary to manually use a cutter to cut the film, thereby reducing the covering efficiency of the entire device and increasing the labor burden of the staff. At the same time, there are safety hazards in manually carrying knives. Utility Model Content

[0031] A cutting frame 13 is fixedly provided at the lower end of the support frame 1 , a cutting knife 14 is movably provided in the cutting frame 13 , and a cutting groove 15 is provided in the cutting frame 13 .

[0032] In this embodiment, the entire device is installed on an agricultural vehicle through a traction ring 2. When it is necessary to cover ridges of different widths, the handle 9 is turned to drive the bidirectional screw 4 to rotate. Since the bidirectional screw 4 is provided with two threaded areas in opposite directions, the two movable seats 5 move in the direction of separation, and the movable seat 5 drives the adjustment frame 6 to move, so that the adjustment frame 6 drives the rotating shaft 7 to move, so that the two rotating shafts 7 move in the direction of separation, and the installation cylinder 25 wrapped with the film is placed between the two rotating shafts 7, and the handle 9 is rotated in opposite directions, so that the two adjusting frames 6 drive the rotating shaft 7 to move in adjacent directions, and the two rotating shafts 7 are inserted into the installation cylinder 25. The installation cylinder 25 is consistent with the width of the film, so that films of different widths can be installed. When the handle 9 is used, the bolt 11 is turned so that the bolt 11 rotates and moves in the direction of the gear ring 8. The bolt 11 drives the clamping block 12 to move along the sliding connection with the support frame 1, thereby clamping the gear ring 8, and the bidirectional screw 4 can be clamped. When the agricultural vehicle moves, the agricultural vehicle drives the entire device to move through the traction ring 2, and the film is pulled, so that the installation cylinder 25 rotates, thereby performing film coating.

[0033] More specifically, the two adjustment frames 6 can be moved by rotating the handle 9, so that the mounting tubes 25 with films of different widths can be installed, and films of different widths can be coated. When a ridge is coated with film, the cutting knife 14 moves so that the cutting knife 14 cooperates with the grass cutting groove to cut the film.

[0034] See also Figure 1-5 As an implementation method for moving the cutting knife 14: a storage chamber 16 is provided in the cutting frame 13, and the cutting knife 14 is movably arranged in the storage chamber 16. Two push rods 17 are fixedly provided on one side of the cutting knife 14, and two sleeves 18 are fixedly provided on one side of the support frame 1. One end of each of the push rods 17 extends into the sleeve 18 and is fixedly connected to a push ring 19. One side of the push ring 19 is provided with a spring 20 movably sleeved on the outside of the push rod 17. One end of the two push rods 17 passes through the sleeve 18 and the support frame 1 and is fixedly connected to a push plate 21. A motor 22 is fixedly provided on one side of the support frame 1, and a convex wheel 23 is fixedly provided on the driving end of the motor 22.

[0035] Specifically, the motor 22 is started, and the motor 22 drives the convex wheel 23 to rotate. When the protruding part of the convex wheel 23 contacts the pushing plate 21, the convex wheel 23 rotates, so that the convex wheel 23 pushes the pushing plate 21, and the pushing plate 21 drives the two pushing rods 17 to move. The pushing rod 17 drives the cutting knife 14 to move out of the storage chamber 16 and cooperates with the cutting groove 15 to cut the film. At the same time, the pushing rod 17 drives the pushing ring 19 to move, and the spring 20 is compressed. When the protruding part of the convex wheel 23 is separated from the pushing plate 21, the spring 20 drives the pushing ring 19 to drive the pushing rod 17, the cutting knife 14 and the pushing plate 21 to move back to the original position. At this time, the cutting knife 14 moves back into the storage chamber 16. For each cutting side, the convex wheel 23 rotates 360 degrees.

[0036] See also Figure 1-5 As an implementation method for limiting the mounting tube 25: two limiting bars 24 are fixedly provided on each of the rotating shafts 7, and mounting tubes 25 are movably provided on the outer sides of the two rotating shafts 7, and limiting grooves 26 matching with the limiting bars 24 are provided on the mounting tubes 25, and one end of each rotating shaft 7 passes through the adjusting frame 6 and is fixedly connected with a gear column 27, and a vertical plate 28 is fixedly provided on the support frame 1, and an electric push rod 29 is fixedly provided on the vertical plate 28, and the driving end of the electric push rod 29 passes through the vertical plate 28 and is fixedly connected with a moving plate 30 that is slidably connected to the support frame 1 through a track, and two limiting blocks 31 matching with the gear column 27 are fixedly provided on one side of the moving plate 30.

[0037] Specifically, when installing the installation cylinder 25, align the limit groove 26 of the installation cylinder 25 with the limit strip 24. When the rotating shaft 7 moves, the rotating shaft 7 drives the limit strip 24 to move into the limit groove 26. One end of the film causes the installation cylinder 25 to rotate under the action of the tension. The installation cylinder 25 drives the rotating shaft 7 to rotate through the limit groove 26 and the limit strip 24. When the entire device stops moving, start the electric push rod 29. The electric push rod 29 drives the moving plate 30 to move along the sliding connection with the support frame 1. The moving plate 30 drives the two limit blocks 31 to move, so that the limit blocks 31 clamp the gear column 27, thereby limiting the gear column 27. The gear column 27 limits the installation cylinder 25 through the rotating shaft 7, the limit strip 24 and the limit groove 26.

[0038] See also Figure 1-5 As an implementation method for pressing down and covering the film: a pressing wheel 32 is rotatably provided at the lower end of each adjusting frame 6, and a turning plate 33 is fixedly provided at the lower end of each adjusting frame 6.

[0039] Specifically, one end of the film is placed on the ridge that needs to be covered, and the entire device is moved so that the pressing wheel 32 presses down on both sides of the film placed on the ridge, and at the same time the turning board 33 is moved. The turning board 33 is tilted so that the turning board 33 turns the soil on the outside of the film to the upper end of the film, thereby covering and fixing both sides of the film.

[0040] To sum up, when the overall equipment is in use:

[0041] When it is necessary to adjust the device according to the width of the film and the ridge, the entire device is installed on the agricultural vehicle through the traction ring 2. When it is necessary to cover the ridges of different widths with films, the handle 9 is turned. The handle 9 drives the bidirectional screw 4 to rotate. Since the bidirectional screw 4 is provided with two threaded areas in opposite directions, the two movable seats 5 move in the direction of separation, and the movable seat 5 drives the adjustment frame 6 to move, so that the adjustment frame 6 drives the rotating shaft 7 to move, so that the two rotating shafts 7 move in the direction of separation, and the installation cylinder 25 wrapped with the film is placed between the two rotating shafts 7, and the limiting groove 26 of the installation cylinder 25 is aligned with the limiting strip 24, and the handle 9 is rotated in opposite directions, so that the two adjusting frames 6 drive the rotating shaft 7 to move in adjacent directions, and the two rotating shafts 7 are inserted into the installation cylinder 25, and the rotating shaft 7 drives the limiting strip 24 to move into the limiting groove 26. The installation cylinder 25 is consistent with the width of the film, so that films of different widths can be installed. At the same time, the adjusting frame 6 drives the pressing wheel 32 and the turning plate 33 to adjust their positions. When the turning handle 9 is used, the bolt 11 is rotated so that the bolt 11 rotates and moves toward the gear ring 8. The bolt 11 drives the clamping block 12 to move along the sliding connection with the support frame 1, thereby clamping the gear ring 8, and thus the bidirectional screw 4 can be clamped. One end of the film is pulled so that it passes through the cutting frame 13 and is placed on the field ridge that needs to be covered. When the agricultural vehicle moves, the agricultural vehicle drives the entire device to move through the traction ring 2, and the pressing wheel 32 rotates, so that the film is placed under the pressing wheel 32, and the two sides of the film placed on the field ridge are pressed down. The film is pulled under the action of the pressing wheel 32, so that the mounting cylinder 25 drives the rotating shaft 7 to rotate through the limit groove 26 and the limit bar 24, thereby covering the film. At the same time, the turning plate 33 moves, and the turning plate 33 is tilted so that the turning plate 33 turns the soil on the outside of the film to the upper end of the film, thereby covering and fixing both sides of the film.

[0042] When it is necessary to limit the installation cylinder 25, after the entire device has completed the film covering of a field ridge, the agricultural vehicle stops moving and the electric push rod 29 is started at the same time. The electric push rod 29 drives the moving plate 30 to move along the sliding connection with the support frame 1, and the moving plate 30 drives the two limit blocks 31 to move, so that the limit blocks 31 clamp the gear column 27, thereby limiting the gear column 27. The gear column 27 limits the installation cylinder 25 through the rotating shaft 7, the limit bar 24 and the limit groove 26.

[0043] When the film needs to be cut, the motor 22 is started, and the motor 22 drives the convex wheel 23 to rotate. When the protruding part of the convex wheel 23 contacts the pushing plate 21, the convex wheel 23 rotates, so that the convex wheel 23 pushes the pushing plate 21, and the pushing plate 21 drives the two pushing rods 17 to move. The pushing rod 17 drives the cutting knife 14 to move out of the storage chamber 16 and cooperates with the cutting groove 15 to cut the film. At the same time, the pushing rod 17 drives the pushing ring 19 to move, and the spring 20 is compressed. When the protruding part of the convex wheel 23 is separated from the pushing plate 21, the spring 20 drives the pushing ring 19 to drive the pushing rod 17, the cutting knife 14 and the pushing plate 21 to move back to the original position. At this time, the cutting knife 14 moves back into the storage chamber 16. For each cutting side, the convex wheel 23 rotates 360 degrees.

[0044] In all the schemes mentioned above, the connection between two parts can be selected according to actual conditions by welding, bolt and nut matching connection, bolt or screw connection or other well-known connection methods, which are not described here one by one. In the above, all fixed connections are preferably welded.
