Description

Technical Field

[0001] This utility model relates to the field of tobacco planting, specifically a mulch film perforation device for tobacco planting. Background Technology

[0002] Mulching technology is widely used in tobacco cultivation. Mulching offers numerous advantages, including heat preservation, moisture retention, weed suppression, and reduced soil erosion, significantly improving tobacco yield and quality. However, after mulching, holes need to be punched in the film to allow tobacco seedlings to emerge and grow. This step currently relies mainly on manual labor, which presents the following problems:

[0003] The traditional method of drilling holes in plastic film mainly relies on manual labor using simple tools to locate and drill holes one by one. The operation is cumbersome and labor-intensive, especially in large tobacco planting bases, where manual drilling consumes a lot of time and manpower. Utility Model Content

[0004] The purpose of this invention is to provide a mulch film punching device for tobacco planting, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

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.

[0022] Please see Figures 1 to 4 In this embodiment of the utility model, a mulch film punching device for tobacco planting has a welded part 9 fixedly connected to the lower part of the frame of the frame 1. An inner frame 8 is fixedly connected to the middle support part of the frame of the welded part 9. A rotating shaft 10 is rotatably connected to the front part of the inner wall of the welded part 9. Wheel axles 13 are fixedly connected to both ends of the rotating shaft 10. A guard strip 5 is symmetrically arranged on the front end of the inner frame of the inner frame 8 near the rotating shaft 10. A connecting block 4 is fixedly connected to the side of the guard strip 5. There are two sets of connecting blocks 4. A mounting seat 14 is fixedly connected to the bottom of each set of connecting blocks 4.

[0023] A connecting plate 16 is fixedly connected to the upper front end of the mounting base 14. A slide rail 25 is fixedly connected to both the upper and lower front ends of the connecting plate 16. A slider 24 is slidably connected to the slot of the slide rail 25. A slider 23 is located at the front end of the slider 24. A connecting plate 20 with left-right displacement is located at the front end of the connecting plate 16. Slide rails 22 are located on both the left and right sides of the back of the connecting plate 20. The end of the slide rail 22 away from the back of the connecting plate 20 is slidably connected to the slider 24. A lifting lug is installed on the top of the connecting plate 20, and a connecting shaft 19 is installed at the axis of the lifting lug. An eccentric rod 18 is fixedly connected to the end of the connecting plate 20 away from the eccentric rod 18 away from the connecting shaft 19. A rotating shaft 17 is fixedly connected to the end of the eccentric rod 18 away from the connecting shaft 19. The rotating shaft 17 is rotatably connected to the center of the front end of the connecting plate 16. A connecting pin block 2 is welded to the center of the front end of the frame 1. A rear wheel bracket 6 is fixedly connected to the rear part of the inner wall of the inner frame 8. The push handle is connected to the wheel axle 13 through the connecting pin block 2. The first sprocket 11 is fixed to the rotating shaft 10. The second sprocket 12 is connected to the driven rod. The bevel gear assembly 26 is installed at the end of the driven rod. One end of the rotating shaft 17 is eccentrically connected to the eccentric rod 18.

[0024] Please see Figures 1-3 A sprocket 11 is fixedly connected to the outer wall of the rotating shaft 10. A sprocket 2 12 is connected to the outer wall of the sprocket 11 via a chain drive. A driven rod is fixedly connected to the shaft center of the sprocket 2 12. The push handle is pushed, and the wheel axle 13 drives the sprocket 11 to rotate. The sprocket 2 12 drives the rotating shaft 17 to rotate via the bevel gear assembly 26. The eccentric rod 18 drives the connecting plate 20 to rotate eccentrically via the connecting shaft 19. The slider 23 slides in the slide rail 22, and the slide rail 22 slides in the groove of the slide rail 25, realizing the compound motion of the connecting plate 20.

[0025] Please see Figures 3-4 A bevel gear assembly 26 is installed on one side of the outer wall of the driven rod. The driven shaft of the bevel gear assembly 26 passes through the back of the connecting plate 16 and is fixedly connected to the back of the rotating shaft 17. A mounting plate 21 is fixedly connected to the front face of the connecting plate 20. A vertical column 29 is installed at the bottom of the mounting plate 21. A hook 30 and a blade 3 are fixed at the bottom of the vertical column 29 respectively. A blade 3 is installed on the upper surface of the outer wall of the hook 30. The mounting plate 21 moves with the connecting plate 20. After the hook 31 pierces the film, the blade 3 enlarges the hole of the film piercing.

[0026] In 1000 cycles of testing, the puncture position error remained stable within 0.3mm. Compared with traditional devices, the membrane breaking efficiency was increased by 45% and the failure rate was reduced by 60%.

[0027] A gripping wheel 15 is fixedly connected to the outer wall of the wheel axle 13 via a connecting rod.

[0028] The working principle of this utility model is as follows:

[0029] Assembly: Welding component 9 is welded to the lower frame of the frame 1 to position the inner frame 8 at the lower part of the inner frame of the frame 1.

[0030] The connecting block 4, which is fixed to the inner side of the outer frame of the inner frame 8, is used for welding the mounting base 14.

[0031] Specifically: The tractor is connected to the connecting pin 2, and the tractor drives the present invention to move, thereby causing the wheel axle 13 to rotate, which in turn drives the rotating shaft 10 to rotate. After the rotating shaft 10 rotates, the sprocket 11 fixed on the outer wall of the rotating shaft 10 drives the sprocket 2 12 to rotate through the chain. The driven rod connected to the shaft center of the sprocket 2 12 drives the bevel gear assembly 26 to operate. The driven shaft of the driven part of the bevel gear assembly 26 brakes the rotating shaft 17 to rotate. The eccentric rod 18 eccentrically connected to one end of the rotating shaft 17 is fixed to the connecting shaft 19. The connecting shaft 19 is connected to the connecting plate 20. After the rotating shaft 17 rotates, it will drive the connecting plate 20 to rotate eccentrically.

[0032] However, the slider 23 connected to the back of the connecting plate 20 is slidably connected to the slide rail 22. At the same time, the slide rail 22 is fixed to the slider 24, which slides in the groove of the slide rail 25 at the front end of the connecting plate 16. When the connecting plate 20 rotates eccentrically, it will cause the connecting plate 20 to move left and right at the front end of the connecting plate 16 and also move up and down at the groove of the slide rail 22. This design helps the connecting plate 20 to be stable during the eccentric rotation process.

[0033] The mounting plate 21 connected to the front end of the connecting plate 20 will also rotate eccentrically. The vertical column 29 connected to the bottom of the mounting plate 21, together with the through hook 31, will first pierce the film. After the mounting plate 21 rotates eccentrically, the through hook 31 will move to the left and drive the blade 3 installed on the outer wall of the hook 30 to enlarge the pierced film hole.

[0034] This effect occurs because the rootstocks of tobacco plants are too large after planting, and traditional small holes cannot accommodate their growth.

[0035] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
