Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery and equipment, specifically a dual-purpose device for ventilating and grouting the mulch film during peanut mulching. Background Technology

[0002] Traditional methods rely heavily on manual labor or single-function tools, resulting in low efficiency and an inability to precisely control the hole spacing. They also suffer from limitations such as limited functionality, poor adaptability, and inconvenient adjustment. Therefore, there is an urgent need for a device that integrates ventilation and film coating functions, allows for flexible mode switching, and enables hole spacing adjustment.

[0003] Compared to patent CN214413661U, the row spacing and plant spacing of the hook holes are not adjustable, and the size of the hook holes is not adjustable, so it cannot be used for making small holes for ventilation. Summary of the Invention

[0004] (a) Purpose of the utility model

[0005] The purpose of this utility model is to provide a peanut ventilation and film-hooking dual-purpose device. This device can conveniently realize ventilation (punching small holes) and film-hooking (hooking large holes) operations of the film during peanut planting. The size and spacing of the hooking holes can be adjusted as needed to improve work efficiency and reduce labor intensity.

[0006] (II) Technical Solution

[0007] The peanut ventilation and film-hooking device of this utility model includes the following components and systems:

[0008] 1. Four-wheeled ridge-riding system:

[0009] The system consists of a horizontal handle (1), a vertical handle (2), a support frame (3), two depth-limiting wheels (4), a ratchet shaft (5), a ground wheel shaft (6), and two ground wheels (7). Specifically, the ground wheel shaft (6) and ratchet shaft (5) are connected by bearings and installed at the front and rear ends of the support frame (3); the ground wheels (7) are fixedly connected to the ground wheel shaft (6) and can rotate with the shaft; the wheel spacing can be adjusted according to the width of the ridge; the depth-limiting wheels (4) are connected by bearings and installed on the ratchet shaft (5), and the wheel spacing can also be adjusted according to the width of the ridge. The horizontal handle (1) can be adjusted laterally, allowing operators to grip it in the same or staggered position as needed while walking; the angle between the vertical handle (2) and the ground is adjustable to accommodate different heights.

[0010] 2. Power transmission system, mode switching and plant spacing adjustment system:

[0011] Power transmission system: including drive chain (8), ratchet shaft sprocket (9), ground wheel shaft sprocket group (10), tensioner (11). Among them, the ratchet shaft sprocket (9) is fixedly connected to the ratchet shaft (5); the ground wheel shaft sprocket group (10) is fixedly connected to the ground wheel shaft (6), and the ground wheel shaft sprocket group (10) contains at least two sprockets with different numbers of teeth, and the number of teeth is less than the number of teeth of the ratchet shaft sprocket (9); the transmission chain (8) meshes with the ratchet shaft sprocket (9), and can also mesh with any sprocket of the ground wheel shaft sprocket group (10); the tension wheel (11) is installed on the switching pressure rod (12), which can adjust the tension of the transmission chain (8); when the ground wheel (7) rotates, the ground wheel shaft sprocket group (10) is driven to rotate through the ground wheel shaft (6), and then the power is transmitted to the ratchet shaft sprocket (9) through the transmission chain (8), thereby driving the ratchet shaft (5) and the ratchet (13) to rotate.

[0012] Mode switching and plant spacing adjustment system: By disengaging the transmission chain (8) from the ratchet shaft sprocket (9) or the ground wheel shaft sprocket group (10), the ratchet can roll forward freely. At this time, the ratchet only rolls simply on the working surface, making small holes for ventilation. By completing the meshing of the transmission chain (8) with any sprocket of the ratchet shaft sprocket (9) and the ground wheel shaft sprocket group (10), the ratchet can be decelerated when it moves forward using the principle of "paradox of the wheel". At this time, the ratchet will generate a large force when it rolls on the mulch film, making larger holes on the working surface. By switching the sprockets with different numbers of teeth in the ground wheel shaft sprocket group (10) to participate in the meshing, the rotation speed of the ratchet (13) can be changed because the transmission ratio between the sprockets with different numbers of teeth and the ratchet shaft sprocket (9) is different, thereby changing the size of the holes and the hole spacing.

[0013] 3. Operating System:

[0014] Two ratchet wheels (13) are fixedly connected to the ratchet shaft (5).

[0015] (III) Beneficial Effects

[0016] 1. Multifunctional integration: One device can perform both hole punching ventilation and film hooking for seedling release, reducing equipment investment.

[0017] 2. Quick switching: The operating mode can be switched by simply adjusting the chain engagement, making it easy to operate.

[0018] 3. Adjustable plant spacing: No parts need to be replaced; simply select different sprockets to adjust the plant spacing to adapt to different planting requirements.

[0019] 4. High stability: The four-wheel ridge-back walking design ensures stable operation and is suitable for different terrains. The accuracy rate of mulching and seedling placement can reach over 98%. Attached Figure Description

[0023] (I) Installation and Debugging

[0024] 1. Adjust the wheel spacing of the ground wheel (7) and the depth limiting wheel (4) according to the width of the peanut planting ridge so that the device can move stably on the ridge.

[0025] 2. Check the installation of the transmission chain (8) to ensure that it meshes well with the ratchet shaft sprocket (9) and the ground wheel shaft sprocket group (10), and adjust the tension of the transmission chain (8) by using the tension wheel (11) so that the chain will not slip during transmission.

[0026] (ii) Ventilation operation (making small holes)

[0027] When ventilation of the mulch film is required, the operator holds the horizontal handle (1) and the vertical handle (2) and pushes the device forward on the ridge. At the same time, the operator operates the switching lever (12) to disengage the transmission chain (8) from the ground wheel axle sprocket assembly (10), at which point the ratchet (13) is in a free-rolling state. As the device moves forward, the ratchet (13) rolls on the mulch film, making small holes in the mulch film to achieve the ventilation function.

[0028] (III) Membrane application (applying for larger holes)

[0029] When a larger hole needs to be made in the mulch film, the switching lever (12) is operated to engage the transmission chain (8) with one of the sprockets in the ratchet shaft sprocket (9) and the ground wheel shaft sprocket assembly (10). When the ground wheel (7) rotates, it drives the ground wheel shaft sprocket assembly (10) to rotate through the ground wheel shaft (6), and then transmits the power to the ratchet shaft sprocket (9) through the transmission chain (8), thereby driving the ratchet shaft (5) and ratchet (13) to rotate. Due to the use of the "paradox of the wheel" principle, the ratchet (13) decelerates as it moves forward, making a larger hole in the mulch film.

[0030] (iv) Adjustment of hook hole size and hole spacing

[0031] If it is necessary to change the size and spacing of the hook holes, the operator can operate the switching lever (12) to disconnect the transmission chain (8) from the currently engaged sprocket, then select a sprocket with a different number of teeth in the ground wheel axle sprocket set (10), and then use the switching lever (12) to engage the transmission chain (8) with the newly selected sprocket. The transmission ratio between the sprocket with a different number of teeth and the ratchet axle sprocket (9) is different, thereby changing the rotation speed of the ratchet (13) and realizing the adjustment of the size and spacing of the hook holes.

Those skilled in the art can make various modifications and variations to this utility model based on the above description. Without departing from the spirit and scope of this utility model, all such modifications and variations should fall within the scope of protection of the claims of this utility model.
