Description

Technical Field

[0001] This utility model relates to the field of agricultural insulation film technology, and in particular to a paddy field insulation film laying device for wheat planting. Background Technology

[0002] Agricultural insulation film typically refers to a plastic film used to cover the soil surface to increase soil temperature, maintain soil moisture, and promote crop growth. This film is mostly made of polyethylene, which has good light transmittance and heat insulation properties. It can reduce heat loss from the ground during cold seasons or at night, providing crops with a more stable and warm growing environment.

[0003] Existing laying methods require the insulation film to be evenly laid on surfaces of different shapes and sizes. However, since it needs to be laid manually, it is easy to cause unevenness of the film layer due to improper operation. Moreover, the laying process is time-consuming. This not only affects the insulation effect in the process of laying insulation film for large buildings or equipment, but also requires a lot of time and labor costs.

[0004] Therefore, this utility model provides a paddy field insulation film laying device for wheat planting. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a paddy field insulation film laying device for wheat planting.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a paddy field insulation film laying device for wheat planting, comprising;

[0007] A folding support assembly, wherein a positioning component is fixedly connected to the outer side of the folding support assembly; the folding support assembly includes an upper transmission arm and a lower transmission arm, and a movable rod is rotatably connected inside the upper transmission arm and the lower transmission arm;

[0008] A laying assembly; the laying assembly includes a rotating shaft rotatably connected to a movable rod, a slide rail support rod rotatably connected to the outside of the rotating shaft, a pulley rotatably connected to the inside of the slide rail support rod, a positioning block fixedly connected to one side of the movable rod, a bolt threadedly connected to the inside of the positioning block, and a positioning ring fixedly connected to one end of the bolt.

[0009] Preferably, the lower drive arm is rotatably connected to a support shaft, and the upper drive arm is rotatably connected to the lower drive arm via the support shaft.

[0010] Preferably, the positioning component includes a fixing block fixedly connected to the outside of the folding support component, and a positioning bolt is inserted inside the fixing block.

[0011] Preferably, the positioning block is provided with an insulating film inside.

[0012] Preferably, one end of the thermal insulation film is in contact with the interior of the positioning block, and the other end of the thermal insulation film is in contact with the positioning ring.

[0013] Preferably, the inner part of the heat-insulating film is fitted onto the outer side of the pulley.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] This invention uses positioning bolts to fix the equipment to the ground, ensuring positional stability during operation. The lower drive arm is fixed to the starting point of the paddy field by a fixing block, ensuring the film's position does not deviate during laying. The insulation film is engaged by positioning blocks and positioning rings, and the sliding pulleys on both sides work with the slide rail support rod for smooth laying. The upper and lower drive arms rotate via a support shaft, allowing flexible control of the film laying process. After the film is laid, it is folded and stored. This design uses rotating bolts to firmly fix the insulation film to the equipment, while the sliding action of the pulleys ensures that the insulation film can be laid smoothly and steadily to the end point of the paddy field. This reduces the difficulty of operation, greatly improves work efficiency, and effectively saves time and labor costs. In addition, the folding function of the upper and lower drive arms allows for easy folding when not in use, effectively reducing the space occupied by the equipment during storage, making the equipment easier to store and transport, further enhancing its practicality and convenience.

[0025] 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.

[0026] like Figure 1 and Figure 4 As shown, this embodiment provides a technical solution: a paddy field insulation film laying device for wheat planting, comprising;

[0027] Folding support assembly 1; Folding support assembly 1 includes an upper transmission arm 11 and a lower transmission arm 12. The lower transmission arm 12 is rotatably connected to a support shaft 13. The upper transmission arm 11 is rotatably connected to the lower transmission arm 12 through the support shaft 13. Movable rods 14 are rotatably connected to the interior of both the upper transmission arm 11 and the lower transmission arm 12.

[0028] The support shaft 13 is a key component connecting the upper drive arm 11 and the lower drive arm 12, allowing the upper drive arm 11 to rotate freely on the lower drive arm 12, thereby flexibly adjusting the working angle of the device to adapt to different terrains and operational needs. At the same time, both the upper drive arm 11 and the lower drive arm 12 are rotatably connected to movable rods 14. These movable rods 14 not only enhance the stability of the structure, but can also be used for further adjustment and support of the entire device, ensuring that the insulation film can be laid flat and wrinkle-free on the ground.

[0029] like Figure 1 , Figure 3 and Figure 4As shown, the laying component 2 includes a rotating shaft 21 rotatably connected to the movable rod 14, a slide rail support rod 22 rotatably connected to the outside of the rotating shaft 21, a pulley 23 rotatably connected inside the slide rail support rod 22, a positioning block 24 fixedly connected to one side of the movable rod 14, an insulation roll film 4 disposed inside the positioning block 24, the insulation roll film 4 being sleeved on the outside of the pulley 23, a bolt 25 threadedly connected inside the positioning block 24, a positioning ring 26 fixedly connected to one end of the bolt 25, one end of the insulation roll film 4 contacting the inside of the positioning block 24, and the other end of the insulation roll film 4 contacting the positioning ring 26.

[0030] The slide rail support rod 22 is rotatably connected to the outer side of the shaft 21 and rotatably connected to the inner side of the pulley 23. It is used to support and guide the laying path of the insulation film. The slide rail support rod 22 ensures the straightness and uniformity of the insulation film laying, reduces the wrinkles and damage of the film material, and improves the laying quality. The pulley 23 is located inside the slide rail support rod 22 to reduce the friction of the insulation film during the laying process, so that the insulation film can be smoothly unfolded. The positioning block 24 is fixedly connected to one side of the movable rod 14 and is provided with the insulation roll film 4 inside. It is used to fix and support the insulation roll film 4. The bolt 25 is threadedly connected to the positioning ring 26. One end is fixedly connected to the positioning block 24 to fix one end of the insulation roll film 4. The use of the bolt 25 provides a firm fixing method to ensure that the insulation roll film 4 will not shift during the laying process and improves the stability of the starting point during laying. The positioning ring 26 contacts the other end of the insulation roll film 4 and is used in conjunction with the bolt 25 to fix the other end of the insulation roll film 4.

[0031] like Figure 1 and Figure 2 As shown, a positioning component 3 is fixedly connected to the outside of the folding support component 1. The positioning component 3 includes a fixing block 31 fixedly connected to the outside of the folding support component 1, and a positioning bolt 32 is inserted inside the fixing block 31.

[0032] The fixing block 31 is fixedly connected to the outside of the folding support assembly 1. As part of the positioning assembly 3, it provides a stable connection point for installing and fixing the positioning bolt 32. The use of the positioning bolt 32 can achieve precise positioning and fixing, ensuring that the device can provide a stable support point when laying, preventing displacement during the laying of the insulation film and thus affecting the laying effect.

[0033] Working principle:

[0034] like Figure 1 - Figure 4 As shown:

[0035] In use: First, insert the positioning bolt 32 into the ground for positioning. Then, fix the lower drive arm 12 at the starting point of the paddy field to be laid using the fixing block 31. Next, place the insulation roll 4 inside the positioning block 24. Then, rotate the bolt 25. The rotation of the bolt 25 moves the positioning ring 26 closer to the outside of the insulation roll 4 until the two sides of the insulation roll 4 are engaged with the two sides of the positioning block 24 and the positioning ring 26 under the push of the bolt 25. Then, slide the insulation roll 4 through the pulley 23. Finally, the insulation roll 4 slides through the pulley 23. Wheel 23 slides inside the slide rail support rod 22 until it reaches the end of the paddy field. Then, the upper drive arm 11 and lower drive arm 12 at one end are pushed. The middle part of the upper drive arm 11 and lower drive arm 12 rotates on the support shaft 13, while the two ends of the upper drive arm 11 and lower drive arm 12 rotate on the movable rod 14. This allows the upper drive arm 11 and lower drive arm 12 to be folded and stored. In this way, the laying of the heat insulation film can be completed, and the device for laying the heat insulation film can be stored, reducing the storage area.

[0036] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
