Greenhouse ridge film laying machine's film laying mechanism

Abstract

This utility model relates to the field of agricultural machinery technology, specifically to the film-laying mechanism of a greenhouse ridging and film-laying machine. It includes a frame, with a film roll rotatably connected to the top of the frame via a damping bushing, and a ridging roller rotatably connected to the bottom of the frame. It also includes a perforation assembly, fixedly installed on the outside of the frame. Through this perforation assembly, the ridging roller drives a crankshaft within the perforation assembly to rotate via a pulley system. When the crankshaft rotates, it drives a connecting rod, which in turn drives a limiting post to slide up and down along the inner wall of the connecting frame. At this time, the insert block moves up and down with the limiting post, completing the perforation action on the laid film. The perforation assembly is stabilized by support frames on both sides of the connecting frame and support wheels at the bottom, ensuring accurate perforation. By setting a film-pressing roller, the film is compacted, ensuring a tight fit between the film and the ridge. This simultaneously completes ridging, film laying, compaction, and perforation operations, improving the operational efficiency of greenhouse planting.

Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, specifically to the film covering mechanism of a greenhouse ridging and film laying machine. Background Technology

[0002] In the field of greenhouse cultivation, ridging and mulching are key steps to ensure the crop growth environment. Usually, ridging and mulching are completed first by a ridging and mulching machine, and then holes are punched in the mulch to meet the needs of crop sowing or transplanting.

[0003] In existing technologies, such as Chinese Patent Publication No. CN220875324U, a double-ridge mulching integrated device for seedling planting is disclosed. During use, controlling the extension and retraction of the tilting telescopic rod allows the frame to be raised away from the ground or lowered closer to it. Three ridge-raising plates form two ridges. Agricultural film is wrapped around a film-wrapping roller. During mulching, the film is tightened by a pressure roller to improve the mulching effect. The film-pressing roller presses down the film covering the two ridges, and a soil-covering plow presses the turned-up soil onto both sides of the film. A height adjustment component allows for adjustment of the installation height of the soil-covering plow to suit different ridge-raising and mulching needs. The device can complete the forming and mulching of two ridges in one operation, effectively improving ridge-raising and mulching efficiency. Simultaneously, a soil-feeding mechanism places soil onto the film, pressing it down to prevent it from being blown off the ridge by wind or other external factors, further ensuring the mulching effect.

[0004] Although the above technical solutions have the above technical advantages, their disadvantages are: after the film covering, the above solutions still need to rely on manual or independent perforation equipment to make secondary perforations on the surface of the film, which cannot overcome the problem of the process of "ridge covering - perforation", and still face the defects of low efficiency of manual perforation and easy damage to the film by independent equipment secondary operation. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a film covering mechanism for a greenhouse ridging and film laying machine, which solves the problem that existing equipment cannot simultaneously complete ridging, film laying and hole opening operations, resulting in low efficiency.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: the film covering mechanism of the greenhouse ridging and film laying machine includes a frame, the top of the frame is rotatably connected to the film roll through a damping bushing, the bottom of the frame is rotatably connected to a ridging roller, and also includes: an opening assembly, the opening assembly is fixedly installed on the outside of the frame, a swing rod is rotatably connected to the outside of the frame, the bottom of the swing rod is rotatably connected to a film pressing roller, the ridging roller rolls on the ground to realize ridging operation, the film roll rotates to release the film, and under the damping action of the damping bushing, the film can always maintain a moderate tension state;

[0007] The punching assembly includes a connecting frame, with support frames fixedly connected to both sides of the connecting frame. Support wheels are rotatably connected to the bottom of the support frames, and a crankshaft is rotatably connected to the top of the support frames. A connecting rod is rotatably connected to the outer side of the crankshaft, and a limit post is rotatably connected to the bottom of the connecting rod. An insert block is fixedly connected to the bottom of the limit post. When the crankshaft rotates, it drives the connecting rod to move, which in turn drives the limit post to slide up and down. At this time, the insert block moves up and down with the limit post, completing the punching action on the laid mulch film.

[0008] Preferably, a telescopic rod is rotatably connected to the inner side of the swing rod, and the end of the telescopic rod away from the swing rod is rotatably connected to the inner side of the frame. A tension spring is fixedly connected to the outer side of the telescopic rod. Under the action of the telescopic rod and its outer tension spring, the pressure roller at the bottom of the swing rod is always in close contact with the surface of the mulch film, pressing the mulch film firmly and making the mulch film tightly adhere to the ridge.

[0009] Preferably, the ridging roller and the crankshaft are driven by a pulley set, and the outer side of the support frame is fixedly connected to the outer side of the frame body. The ridging roller can drive the crankshaft in the hole assembly to rotate through the pulley set.

[0010] Preferably, the connecting rods are linearly arranged along the central axis of the crankshaft, and the outer wall of the limiting post is slidably connected to the inner wall of the connecting frame. The connecting rods can drive the limiting post to slide up and down along the inner wall of the connecting frame, and at this time the insert block moves up and down together with the limiting post.

[0011] The beneficial effects of this utility model are as follows:

[0012] (i) This mechanism incorporates an opening assembly. The ridging roller drives the crankshaft within the opening assembly to rotate via a pulley system. As the crankshaft rotates, it drives the connecting rod, which in turn causes the limiting post to slide up and down along the inner wall of the connecting frame. Simultaneously, the insertion block moves up and down with the limiting post, completing the drilling action on the laid mulch film. The opening assembly is stabilized by support frames on both sides of the connecting frame and support wheels at the bottom, ensuring accurate drilling positioning.

[0013] (ii) By setting up a film pressing roller, the film pressing roller at the bottom of the swing rod on the outside of the frame is always in close contact with the surface of the ground film under the action of the telescopic rod and the tension spring on its outside, so as to compact the ground film and make the ground film fit tightly with the ridge. This can prevent the ground film from shifting during drilling and subsequent operations. Through the coordinated cooperation of various components, the ridge, film laying, compaction and hole opening operations are completed simultaneously, which improves the operation efficiency of greenhouse planting.

[0020] 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.

[0021] Example: Please refer to Figure 1-5 This utility model provides a technical solution: a film covering mechanism for a greenhouse ridging and film laying machine, including a frame 1, the top of the frame 1 is rotatably connected to a film roll 2 via a damping bushing, the bottom of the frame 1 is rotatably connected to a ridging roller 3, and also includes: an opening assembly 4, the opening assembly 4 is fixedly installed on the outside of the frame 1, the outside of the frame 1 is rotatably connected to a swing rod 5, the bottom of the swing rod 5 is rotatably connected to a pressure roller 6, which pulls out the film on the film roll 2 and passes it under the pressure roller 6 to fix it to the ground. When the mechanism starts to be pulled by the traction mechanism, the frame 1 serves as an overall support structure, the ridging roller 3 rolls on the ground to realize ridging operation, the film roll 2 rotates to release the film, and under the damping action of the damping bushing, the film can always maintain a moderate tension. As the mechanism moves forward, the film gradually covers the ridging ridge formed by the ridging roller 3.

[0022] The perforation assembly 4 includes a connecting frame 41, with support frames 42 fixedly connected to both sides of the connecting frame 41. A support wheel 43 is rotatably connected to the bottom of the support frame 42, and a crankshaft 44 is rotatably connected to the top of the support frame 42. A connecting rod 45 is rotatably connected to the outer side of the crankshaft 44, and a limiting post 46 is rotatably connected to the bottom of the connecting rod 45. An insert block 47 is fixedly connected to the bottom of the limiting post 46. The ridging roller 3 is driven by a pulley system to rotate the crankshaft 44. The outer side of the support frame 42 is fixedly connected to the outer side of the frame 1. The connecting rod 45 is linearly arranged along the central axis of the crankshaft 44. The outer wall of the limiting post 46 is slidably connected to the inner wall of the connecting frame 41. The crankshaft 44 in the perforation assembly 4 rotates via the pulley system. When the crankshaft 44 rotates, it drives the connecting rod 45 to move, which in turn drives the limiting post 46 to slide up and down along the inner wall of the connecting frame 41. At this time, the insert block 47 moves up and down with the limiting post 46, completing the perforation action on the laid mulch film. The hole-drilling assembly 4 is kept stable by the support frames 42 on both sides of the connecting frame 41 and the support wheels 43 at the bottom, ensuring accurate drilling position.

[0023] A telescopic rod 7 is rotatably connected to the inner side of the swing rod 5. The end of the telescopic rod 7 away from the swing rod 5 is rotatably connected to the inner side of the frame 1. A tension spring 8 is fixedly connected to the outer side of the telescopic rod 7. Under the action of the telescopic rod 7 and the tension spring 8 on its outer side, the film pressing roller 6 at the bottom of the swing rod 5 on the outer side of the frame 1 is always in close contact with the surface of the ground film, pressing the ground film and making the ground film fit tightly with the ridge. This can prevent the ground film from shifting during drilling and subsequent operations. Through the coordinated cooperation of various components, the ridge, film laying, compaction and hole opening operations are completed simultaneously, which improves the operation efficiency of greenhouse planting.

[0024] Working principle: When in use, the mulch film on the mulch film roll 2 is pulled out and wrapped around the ground from under the pressure roller 6. When the mechanism starts to be pulled by the traction mechanism, the frame 1 serves as the overall support structure. The ridging roller 3 rolls on the ground to realize the ridging operation. The mulch film roll 2 rotates to release the mulch film. Under the damping action of the damping bushing, the mulch film can always maintain a moderate tension. As the mechanism moves forward, the mulch film gradually covers the ridges formed by the ridging roller 3.

[0025] Simultaneously, the crankshaft 44 in the perforation assembly 4 is rotated via the pulley set. As the crankshaft 44 rotates, it drives the connecting rod 45, which in turn causes the limiting post 46 to slide up and down along the inner wall of the connecting frame 41. At this time, the insertion block 47 moves up and down together with the limiting post 46, completing the perforation action on the laid mulch film. The perforation assembly 4 is stabilized by the support frames 42 on both sides of the connecting frame 41 and the support wheel 43 at the bottom, ensuring accurate perforation positioning.

[0026] During this process, the pressure roller 6 at the bottom of the swing rod 5 on the outside of the frame 1, under the action of the telescopic rod 7 and the tension spring 8 on its outside, always sticks tightly to the surface of the ground film, compacts the ground film, and makes the ground film fit tightly with the ridge. This can prevent the ground film from shifting during drilling and subsequent operations. Through the coordinated cooperation of various components, the ridge-making, film laying, compaction and hole-making operations are completed simultaneously, which improves the operating efficiency of greenhouse planting.
