Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of field ridge film covering, and in particular relates to a field ridge film covering device. Background Art
[0002] The ridges are the raised parts in the field. The ridges are used to achieve a high and level ground, thereby preventing water accumulation during the planting process that would soak the seedlings or seeds and affect the growth and development of the plants.
[0003] Ridge operation is to raise ridges in the field through the operation of specific agricultural machinery, such as rotary tillers. During the ridge planting operation, it is necessary to cover the ridges with film to protect the planted seeds or young shoots, such as keeping warm, preventing rain, and preventing birds from pecking. Specifically, during the film covering process, a film covering machine is used for film covering. The film covering machine is hung on the operating machinery, such as a tractor, by pulling and hanging. Efficient film covering of the ridges is achieved.
[0004] During the film covering process, the existing film covering equipment unwinds the film and covers it on the ridges. However, after the film is covered, its edge cannot be compacted with the ridge base, so once the wind blows, the film is easily overturned from the ridges. Therefore, in the prior art, soil is pressed on the edge of the film to prevent it from being overturned by wind.
[0005] However, in the actual working process, it was found that although the film was pressed by the soil after unrolling, it was not compacted onto the ridge base, and the soil pressing edge could not achieve a perfect pressing edge. As a result, the film was still easily overturned in strong wind conditions, especially when the edge of the film was not fully compacted. Under the action of wind, the uncompacted part was directly turned over, which produced a chain reaction and caused a large area of film to be overturned. Utility Model Content
[0006] Based on the above background, the purpose of the utility model is to provide a ridge film covering device.
[0007] In order to achieve the above objectives, the utility model adopts the following technical solutions:

[0038] Example 1
[0039] like Figure 1-5 As shown, a ridge film covering device includes a film covering frame 1. The specific structure of the film covering frame 1 is as follows: the film covering frame 1 includes a film covering rod frame arranged at intervals in front and back, and a plurality of coil insertion rods 8 are fixedly connected to the top of the film covering rod frame. The film coil is inserted on the insertion rod 8 to achieve sufficient film coil storage during the operation.
[0040] At the same time, the same as the existing method, the hangers 4 are welded at the left and right ends of the film laminating frame 1 to facilitate hanging on the working equipment such as a tractor. The same as the existing method, the film laminating rod frame is respectively equipped with a plurality of roller assemblies. The roller assembly includes a roller frame 3, and the front and rear sides of the roller frame 3 are respectively rotatably connected with rollers 31.
[0041] After the equipment is pulled and hung, the whole device can move along the ridges in the field and cover the fields with film.
[0042] Both ends of the film covering frame 1 are respectively equipped with film placing mechanisms, which are used to place the film covering the field ridges.
[0043] In order to fully compact the two edge parts of the film unwound and covered on the ridge and reduce the defect of being blown over by wind, the ridge covering device also includes a film edge pressing mechanism 6 respectively installed and connected to the two ends of the film covering frame 1.
[0044] Specifically, the film edge clamping mechanism 6 includes spring arms 61 respectively hinged on both sides of the coating frame 1 (the spring arms 61 are hinged through a hinge axis), and the shape of the spring arms 61 is: the spring arm 61 includes a vertical arm portion hinged on the outer wall of the coating rod frame, and the spring base is welded to the inner wall of the vertical arm portion; the vertical arm portion is integrally formed with a horizontal arm portion, and the horizontal arm portion is integrally formed with a protrusion 62.
[0045] Meanwhile, a plurality of edge pressing wheels 63 are respectively mounted and connected to the protruding parts; specifically, the axles of the edge pressing wheels 63 are rotatably connected to the protruding parts 62, and the edge pressing wheels 63 are located at the inner side of the roller.
[0046] During the operation, after film coating (during the film coating process, the rollers roll on both sides of the field ridge), the film is compacted by the edge pressing wheels 63 on both sides.
[0047] During the compaction process, in order to maintain a high contact pressure and cope with the uneven field geographical environment during the contact and compaction process, the edge pressing wheel 63 is designed to be a spring pressing method, and during the bumpy process, the spring structure is used to achieve the up and down swinging of the wheel body, so as to avoid crushing the film and ensure that the film can be contacted and compacted smoothly.
[0048] Specifically, the spring arm 61 and the coating frame 1 are tensioned by a spring structure, and the spring structure includes a spring base 611 fixedly connected to the spring arm 61, and a plurality of bent springs 64 are fixedly connected to the top of the spring base 61, and the bent springs 64 are fixedly connected to the bottom of the coating frame 1.
[0049] During the working process, first, under the elastic force of the curved spring 64, the spring arm 61 always keeps the downward pressure state, thereby maintaining a high contact pressure of the edge pressing wheel 63. When encountering bumps, at this time, the spring arm 61 acts as a buffer structure to achieve buffering (the deformation of the spring to form a buffer is a conventional application based on the inherent properties of the spring in the prior art), which is manifested in the continuous swinging of the spring arm 61, thereby avoiding the defect of the film being crushed by force when the pressure wheel cannot encounter obstacles.
[0050] Example 2
[0051] like Figure 1-5As shown, based on the structure of Example 1, the film unwinding mechanism comprises rotating seats 21 respectively connected to the inner side wall of the film-covering rod frame (same as the existing method, connected by a rotating shaft), and a plurality of film-piercing rods 22 are detachably assembled and connected between the rotating seats 21. Specifically, the fastening bolts for fastening the film-piercing rods 22 are threadedly connected to the rotating seats 21. After removing the fastening bolts, the film roll is inserted into the film-piercing rods to achieve unwinding. After unwinding is completed, the rotating seat 21 is rotated to continue unwinding.
[0052] At the same time, the top of the coating rod frame is fixedly connected with a locking structure for locking the rotating seat 21. The locking structure includes a locking column 7, and the locking column 7 is threadedly connected with a contact screw 71 that contacts and presses on the rotating seat 21.
[0053] During the unwinding process, the contact and pressure screw 71 is kept in contact with the rotating seat 21, and the rotating seat 21 is locked. During the process of switching the coiling die, the contact and pressure screw is released and the rotating seat 21 rotates to switch the coiling.
[0054] The above method can achieve the continuity of film unloading during the unloading process, avoid frequent replacement of coils during the unloading process, and thus improve the film unloading efficiency.
[0055] Example 3
[0056] like Figure 1-5 As shown, based on the structure of Example 1, in order to achieve film tensioning and maintain a relatively stable posture to cover the field ridges, the left and right ends of the above-mentioned film covering rod frame are respectively equipped with film tensioning structures.
[0057] Specifically, the film tensioning structure includes an adjustment rod 51 assembled and connected to the side walls of the film covering rod frame facing each other, and two film tensioning rods spaced apart from each other are fixedly connected between the adjustment rods 51. The film is inserted between the film tensioning rods and covers the field ridges.
[0058] In order to achieve tensioning, the adjusting rod 51 is provided with an adjusting opening 511 , and the film-coated rod frame is fixedly connected with a locking screw 53 passing through the adjusting opening 511 , and the locking screw 53 is threadedly connected with a nut that is pressed and locked on the adjusting rod 51 .
[0059] Specifically, if the film is too loose, the operator loosens the nut and lifts the film tensioning structure upward. During this process, the film tensioning structure lifts the film to tension it. During this process, the locking screw 53 slides relative to the adjustment port 511, and is locked again by the nut after adjustment. On the contrary, if the film is too tight, the film tensioning structure is lowered.
[0060] Similarly, rotational tensioning is achieved, that is, the nut is loosened for rotational tensioning and then tightened again.
[0061] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
