Description

Technical Field

[0001] This utility model relates to the field of mulch film laying technology, specifically to an integrated mulch film laying and pressing device. Background Technology

[0002] The statements herein provide only background information related to this invention and do not necessarily constitute prior art.

[0003] Mulching is a crucial step in crop cultivation. However, current integrated mulching and pressing equipment is mostly designed for large-scale, patch planting, and is not well-suited for small-scale planting, greenhouse cultivation, or ridge planting.

[0004] Taking strawberry and other strawberry planting on raised beds and the laying of reflective film between fruit tree rows as examples, the current common practice is to lay the film manually and then press it down. This method is inefficient and labor-intensive. Utility Model Content

[0006] To achieve the above objectives, the technical solution of this utility model is as follows: an integrated film laying and pressing device, comprising:

[0007] The rotating shaft has pressure plates at both ends. The pressure plates press the two sides of the laid mulch film into the soil by rolling and pressing down relative to the ground.

[0008] The handheld pole has one end connected to the pivot and the other end for holding, and a plastic film support is installed on it;

[0009] The mulch film unwinding shaft is mounted on the mulch film support and is used to thread the mulch film rolls and unwind them.

[0010] Furthermore, the plastic film support is positioned on the side of the hand handle near the pivot to lower the overall center of gravity of the equipment.

[0011] Furthermore, it also includes a guide shaft, which is located on the side of the pressure plate away from the mulch film support, and the guide shaft is connected to a rotating shaft or a hand handle via a connecting plate.

[0014] Furthermore, the connecting plate is hollow inside, and the transmission assembly consists of two transmission wheels and a transmission belt or chain connecting the two transmission wheels. One transmission wheel is located at one end of the guide shaft, and the other transmission wheel is located at one end of the rotating shaft. When the rotating shaft rotates, it can synchronously drive the guide shaft to rotate. The diameter of the transmission wheel on the guide shaft is smaller than the diameter of the transmission wheel on the rotating shaft.

[0034] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. Obviously, the described embodiments are only a part of the embodiments of the utility model, and not all of them. Unless otherwise specified, the embodiments and features described in this application can be combined with each other. All other embodiments obtained by those skilled in the art based on the embodiments of the utility model without creative effort are within the scope of protection of the utility model.

[0035] See Figures 1 to 3 .

[0036] This utility model discloses an integrated film laying and pressing device, comprising:

[0037] The rotating shaft 1 has pressure plates 11 at both ends. The pressure plates 11 press the two sides of the laid mulch film into the soil by rolling and pressing down relative to the ground.

[0038] Handheld lever 2, one end of which is connected to the rotating shaft 1, and the other end is used for handholding. A plastic film support 21 is fixedly installed on it. The plastic film support 21 is located on the side of the handheld lever 2 near the rotating shaft 1 to lower the overall center of gravity of the equipment.

[0039] The mulch film unwinding shaft 3 is rotatably mounted on the mulch film support 21 and is used to thread the mulch film roll and unwind the mulch film roll.

[0040] In practice, the plastic film roll is threaded onto the plastic film unwinding shaft 3, and then the plastic film unwinding shaft 3 is placed on the plastic film support 21. Initially, a portion of the plastic film is manually pulled down and pressed under the pressure plate 11. Then, the pressure plate 11 is moved by the hand lever 2. While pressing the two sides of the plastic film into the soil, the plastic film is automatically unwound due to the displacement of the hand lever 2 (and the downward pressure of the pressure plate 11). (At this time, the user can work backwards, with the equipment in front of the user). The pressure of the pressure plate 11 comes from the weight of the equipment itself, and the pressure can be provided to the pressure plate 11 by manually applying pressure to the hand lever 2.

[0041] Compared with the traditional method of manually covering and pressing the film, this invention has higher work efficiency and relatively reduced labor intensity. It can simultaneously cover and press the film, and has a simple and compact structure, making it suitable for mulching crops with small row spacing.

[0042] In one embodiment, a guide shaft 4 is also included, which is located on the side of the pressure plate 11 away from the mulch film support 21. The guide shaft 4 is connected to the rotating shaft 1 or the hand handle 2 via a connecting plate 5. With this design, during use, a portion of the mulch film can be manually pulled off, bypassed by the guide shaft 4, and then pressed under the pressure plate 11, thus eliminating the need to walk backwards during use and improving comfort.

[0043] In one embodiment, the rotating shaft 1 is rotatably engaged with the hand lever 2, the pressure plate 11 can rotate synchronously with the rotating shaft 1, one end of the connecting plate 5 is rotatably engaged with the guide shaft 4, and a limiting rod 6 is connected between the connecting plate 5 and the hand lever 2. The limiting rod 6 is used to limit the relative position of the connecting plate 5 and the hand lever 2; the limiting rod 6, the connecting plate 5 and the hand lever 2 form a stable triangular structure.

[0044] The guide shaft 4 has spiral friction grooves 41 with opposite directions of rotation at both ends, and also includes a transmission assembly (not shown in the figure) for driving the guide shaft 4 to rotate, and making the distance moved by any point on the guide shaft 4 per unit time greater than the unwinding length of the mulch film in the corresponding time.

[0045] In practice, since the distance that any point on the guide shaft 4 moves per unit time is greater than the unwinding length of the mulch film within the corresponding time, the guide shaft 4 rotates relative to the mulch film on it. Since the two ends of the guide shaft 4 are provided with spiral friction textures 41 with opposite directions of rotation, when the guide shaft 4 rotates, the friction textures 41 on it can push the two sides of the mulch film to extend outward, achieving the effect of a rolling roller and rolling the two sides of the mulch film flat.

[0046] Preferably, the transmission assembly can be made of an electric motor.

[0047] In one embodiment, the connecting plate 5 is hollow inside, and the transmission assembly consists of two transmission wheels and a transmission belt or transmission chain connecting the two transmission wheels. One transmission wheel is located at one end of the guide shaft 4, and the other transmission wheel is located at one end of the rotating shaft 1. When the rotating shaft 1 rotates, it can synchronously drive the guide shaft 4 to rotate. The diameter of the transmission wheel on the guide shaft 4 is smaller than the diameter of the transmission wheel on the rotating shaft 1.

[0048] In practice, when a drive belt is used, the drive wheel is a pulley; when a drive chain is used, the drive wheel is a sprocket.

[0049] In one embodiment, one end of the limiting rod 6 is rotatably connected to the connecting plate 5, and a slip ring 61 is slidably provided on one end of the limiting rod 6 corresponding to the hand handle 2. The slip ring 61 is rotatably engaged with the hand handle 2, and a first limiting member 62 is provided on the slip ring 61 to limit the relative position between the slip ring 61 and the limiting rod 6. With this design, when it is necessary to adjust the angle between the hand handle 2 and the connecting plate 5, the limiting of the limiting rod 6 can be released and then re-limited, making it convenient for the user to use according to their own habits.

[0050] Preferably, the first limiting member 62 includes a screw hole on the slip ring 61, and a screw is provided in the screw hole. Rotating the screw can move it towards the limiting rod 6, pressing against the limiting rod 6, thereby limiting the relative position of the slip ring 61 and the limiting rod 6.

[0051] In one embodiment, the mulch film support 21 has placement grooves 22 at both ends of the mulch film unwinding shaft 3. The two ends of the mulch film unwinding shaft 3 are rotatably placed in the placement grooves 22. Limiting plates 31 are respectively provided at both ends of the mulch film unwinding shaft 3. The limiting plates 31 can move along the length direction of the mulch film unwinding shaft 3 and are limited by the second limiting member.

[0052] The pressure plate 11 can move along the length of the rotating shaft 1 and is limited by the third limiting member 12.

[0053] In specific implementation, a rotating component (e.g., a bearing) can be installed at the corresponding placement groove 22 position of the mulch film unwinding shaft 3 to allow rotation relative to the mulch film support 21. A baffle can be installed on the outside of the placement groove 22 to prevent the mulch film unwinding shaft 3 from displacing relative to the mulch film support 21. The setting of the limiting plate 31 and the displacement of the pressure plate 11 are to adapt to mulch films of different widths and to lay surfaces of different widths. The specific structure of the second limiting member and the third limiting member 12 can be roughly the same as the structure of the first limiting member 62. The limiting is achieved by opening screw holes on the corresponding components and setting screws in the screw holes, and by the tightening of the screws. Of course, other limiting methods commonly used in the prior art can also be used for limiting. For the second limiting member, threads can also be opened on both sides of the mulch film unwinding shaft 3, and then the limiting plate 31 can be screwed into the mulch film unwinding shaft 3, which can also play a certain role in preventing the mulch film unwinding shaft 3 from displacing relative to the mulch film support 21.

[0054] Preferably, the pressure plate 11 can also be removed from the rotating shaft 1 for replacement. Replacing the pressure plate 11 with one of different diameters enables the application to be used in different terrains and for different types of plants.

[0055] In one embodiment, a first gear 13 is provided in the middle of the rotating shaft 1, and a power component 7 is provided on the hand handle 2. The output end of the power component 7 is provided with a second gear 71 that meshes with the first gear 13. The power component 7 is used to drive the first gear 13 to rotate.

[0056] In practice, a control button is also included. The control button is located on the end of the hand lever 2 away from the rotating shaft 1 and is used to control the start of the power component 7. The power component 7 can be used as an assist component to reduce the resistance when the user moves forward (so the power component 7 has low energy consumption). Of course, the power component 7 can also be used directly as the main driving force to drive the equipment forward. The user can mainly control the direction.

[0057] Preferably, the power unit 7 can be an electric motor, a small gasoline engine or a diesel engine from the prior art; when it is an electric motor, a battery module can be added to the hand lever 2 to provide power to the motor. The battery module, the motor and other parts of the equipment work together as a load-bearing element to ultimately transfer the gravity to the pressure plate 11, so that the workers do not need to apply a lot of downward pressure, but can press the mulch film into the soil by the weight of the equipment itself.

[0058] In one embodiment, the hand lever 2 is Y-shaped, with the top of the Y-shape rotatably engaging with the rotating shaft 1. The first gear 13 and the power component 7 are located in the middle of the fork of the Y-shape. This design improves the overall stability of the equipment, making it less prone to deviation during movement and facilitating directional control.

[0059] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.

[0060] It should be noted that if the utility model embodiment involves directional indicators (such as up and down), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0061] Furthermore, the meaning of "and / or" throughout the text includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or a solution that simultaneously satisfies A and B. Additionally, if the utility model embodiments involve descriptions of "first," "second," etc., these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Therefore, features defined with "first" or "second" can explicitly or implicitly include at least one of those features. Furthermore, "multiple" refers to two or more. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by the utility model.
