Description
Technical Field
[0001] The utility model belongs to the technical field of field ridge covering film, and in particular relates to a field ridge covering film edge pressing device. Background Art
[0002] The ridge is a raised part in the field, and the top of the ridge is higher than the field ground. By raising the ridge, a planting environment higher than the field ground is provided for the plants to be planted during the planting process, which can prevent waterlogging and weeds from affecting their growth.

However, after the film is covered, its edge and the top surface of the film cannot be compacted with the ridge surface and the ridge base (the position between the ridge and the ground), resulting in the film being easily overturned from the ridge once the wind blows.
[0005] Although, during the operation, the film is pressed by soil, the film that is not fully compacted is still easily overturned by wind because of the insufficient tightness of the cover. Utility Model Content

[0032] 3. The top and side positions of the film are fully compacted by the device disclosed in the utility model, which effectively solves the technical defect that the film is easily overturned by the wind due to the low compactness of the covering. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] Example 1
[0043] like Figure 1-4 As shown, a ridge film covering edge pressing device includes edge pressing mechanisms arranged at intervals on the front and rear sides. The edge pressing mechanism presses the two sides of the covered film during the edge pressing process. That is, during the working process, the edge pressing mechanism rolls on the front and rear sides of the ridge.
[0044] Specifically, the edge pressing mechanism includes an edge pressing frame 1 (according to the existing method, a hanging structure such as a hanging ring is welded at the end of the edge pressing frame 1, so that it can be hung on agricultural machinery such as tractors by means of steel wire ropes, etc., so as to work in the field), and the side walls of the edge pressing frame 1 facing each other are equipped with a plurality of edge pressing wheel assemblies, and the edge pressing wheel assemblies include a wheel body and a wheel barrel 211 fixedly connected to the wheel body 21 (the wheel barrel 211 is convexly arranged to face inwards, so as to facilitate the bottom edge of the film to be compacted onto the ridge base of the field ridge). The wheel barrel 211 is fixed on the contour of the wheel body 21 to increase the width of the edge pressing and improve the compaction effect.
[0045] At the same time, the wheel body 21 is rotatably connected to a wheel axle, and the wheel axle is fixedly connected to a buffer seat 22, and the buffer seat 22 is slidably installed on the edge pressing frame 1 through a spring buffer structure.
[0046] Specifically, the edge pressing frame 1 is provided with a plurality of inner sliding openings, and the buffer seat 22 is slidably connected in the inner sliding openings. The spring buffer structure includes an inner sliding rod fixedly connected in the inner sliding opening, and the inner sliding rod is slidably connected to the buffer seat 22; the spring buffer also includes an upper spring 221 and a lower spring 222 sleeved on the inner sliding rod, one end of the upper spring 221 and the lower spring 222 are respectively fixedly connected to the top and the bottom, and the other ends of the upper spring 221 and the lower spring 222 are respectively fixedly connected to the top and the bottom of the inner sliding opening.
[0047] In the process of working edge pressing, the upper spring 221 and the lower spring 222 are used to form a buffer on the uneven ground. When encountering obstacles, the elastic action of the buffer seat 22 and the upper spring and the spring is used to realize the up and down swing of the carrying wheel body 21 and the wheel drum 211. In this process, it is realized to avoid the film being crushed by the obstacles (such as stones) and the roller of the wheel body 21 due to excessive contact pressure when encountering obstacles. That is, the buffer seat 22-wheel body 21 structure with a buffer design realizes elastic swing, that is, maintains a high pressing strength, and can protect the film during the edge pressing process in the uneven field operation process.
[0048] Example 2
[0049] like Figure 1-4As shown, based on the structure of Example 1, the field ridge film covering and edge pressing device of this embodiment further includes a plurality of film rolling mechanisms arranged between the edge pressing mechanisms; specifically, the field ridge film covering and edge pressing device further includes four film rolling mechanisms arranged between the edge pressing mechanisms; two film rolling mechanisms are located at the left and right end positions of the edge pressing frame 1 (the spacing between the two film rolling mechanisms at this position and the edge pressing frame 11 is adjusted by the spacing adjustment structure;), and the remaining film rolling mechanisms are located at the middle position of the edge pressing frame 1. Specifically, the spacing adjustment structure includes a plurality of mounting screws 11 fixedly connected to the outer side wall of the pressure roller frame, and the mounting screws 11 are slidably connected to the edge pressing frame; a pair of nuts positioned on the side walls of the edge pressing frame are threadedly connected to the mounting screws 11.
[0050] This method can adjust the width of the edge pressing frames 1 on both sides according to the width of the ridge during the working process. The method is to loosen the nut, slide it for adjustment, and then lock it with the nut.
[0051] By means of four film rolling mechanisms arranged between the edge pressing mechanisms, during the compaction of the edge portion of the film, the film and the ridge top of the field ridge are compacted, thereby ensuring that the covering template is fully compacted from the edge to the ridge top.
[0052] Specifically, the film rolling mechanism includes a pressing roller 31, both ends of which are rotatably connected to a rotating shaft, the rotating shaft is fixedly connected to a convex seat 311, and the convex seat 311 is assembled and connected to a pressing roller frame 32. Specifically, the film rolling mechanisms located at the left and right end positions of the edge pressing frame 1 are fixedly connected by connecting beams arranged at intervals in front and back; the two film rolling mechanisms located in the middle position of the edge pressing frame 1 are adjustably mounted on the connecting beams.
[0053] Specifically, the two film rolling mechanisms in the middle position are adjustable in position, so that the distance between the film rolling mechanisms can be adjusted during operation. For example, when the compaction degree of the top of the film is not high, the two film rolling mechanisms in the middle are brought closer to the film rolling mechanism at the end position on one side to increase the density of the rolling structure. In this way, when the compaction degree of the film is not high after covering the film, for example, when the film is too scattered, concentrated compaction can be achieved.
[0054] On the contrary, when the compaction degree of the film is moderate, the rolling efficiency is improved by maintaining a sufficient distance between the film rolling mechanisms, so that a longer length of film can be compacted in one rolling operation.
[0055] The above-mentioned connecting beam is provided with a long adjustment slide, and the two film rolling mechanisms located in the middle of the edge pressing frame 1 are fastened to the long adjustment slide through the adjustment screw A; the adjustment screw A is fixedly connected to the top of the pressing roller frame 32, and the adjustment screw A passes through the long adjustment slide. The thread on the adjustment screw A is connected to the contact nut on the top of the connecting beam. After loosening the contact nut, the two film rolling mechanisms in the middle position can be adjusted.
[0056] Example 3
[0057] like Figure 1-4 As shown, this embodiment is based on the structure of the second embodiment, and has the same principle as the wheel body 21 to compact the film in a buffering manner, so as to protect the film during compaction. A sliding rod is fixedly connected inside the pressing roller frame 32 (the longitudinal cross-section of the pressing roller frame 32 is U-shaped, i.e., a U-shaped frame), and the convex seat 311 is slidably connected to the sliding rod; similarly, the upper and lower ends of the sliding rod are respectively sleeved with the first spring 33 and the second spring 34. One end of the first spring 33 and the second spring 34 are respectively fixedly connected to the top and the bottom of the convex seat 311; the other ends of the first spring 33 and the second spring 34 are respectively fixedly connected to the top and the bottom of the pressing roller frame 32.
[0058] Similarly, during the process of compacting the film, when encountering obstacles such as raised stones or hard mud blocks, the first spring 33 and the second spring 34 cooperate with each other (that is, the first spring 33 is stretched or compressed and the second spring 34 is compressed or stretched to cooperate with the up and down swinging of the roller body), so that the convex seat 311 carries the roller body to swing elastically, forming an elastic displacement, thereby avoiding the defect of directly rolling over and easily crushing the film when the inelastic structure is designed.
[0059] 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.
