Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and more specifically to an integrated machine for laying double mulch film and drip irrigation tape. Background Technology

[0002] To conserve water, drip irrigation tapes are used for watering crops in existing farmland, and white plastic film is also laid to retain water. To improve agricultural efficiency, integrated drip irrigation tape and plastic film laying machines have been developed, such as CN208317729U-Drip Irrigation Tape and Plastic Film Laying Device and Kit, Integrated Drip Irrigation Tape and Plastic Film Laying Machine, and CN216874194U-An Integrated Intelligent Laying System for Plastic Film and Drip Irrigation Tape.

[0003] However, the existing equipment mentioned above can only lay a layer of white mulch, which is mainly used to reflect sunlight, reduce the temperature of the soil surface, prevent seeds from being burned by high temperature, and maintain soil moisture to promote seed germination. It does not have the function of suppressing weeds, preventing weed growth, or reducing the competition of weeds for crops.

[0004] Therefore, how to provide a machine that can simultaneously lay black and white mulch film and drip irrigation tape to achieve three functions in one machine, improve agricultural work efficiency, whereby the black mulch film inhibits weed growth, the laid white mulch film lowers the soil surface temperature to prevent seeds from being burned by high temperatures, and at the same time helps to maintain soil moisture and promote seed germination, and the laid drip irrigation tape achieves water-saving and water-free effects, is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] In view of this, the present invention provides an integrated machine for laying double mulch film and drip irrigation tape to solve the above-mentioned technical problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A double-film mulch and drip irrigation tape laying integrated machine, comprising:

[0008] frame;

[0009] A drip irrigation tape placement shaft is mounted on the frame, and two drip irrigation tape reels are sleeved on the drip irrigation tape placement shaft;

[0010] A white plastic film placement shaft is mounted on the frame and located on one side of the drip irrigation tape placement shaft. A white plastic film roll is sleeved on the white plastic film placement shaft.

[0011] A black plastic film placement shaft is mounted on the frame and located on the other side of the drip irrigation tape placement shaft. A black plastic film roll is sleeved on the black plastic film placement shaft.

[0012] A film pressing shaft assembly is mounted on the frame and located below the white mulch film placement shaft. The white mulch film on the white mulch film roll, the black mulch film on the black mulch film roll, and the drip irrigation tape on the drip irrigation tape roll are all pressed against the underside of the film pressing shaft assembly.

[0013] The white mulch film is laid on top of the black mulch film and the two drip irrigation tapes. The two drip irrigation tapes are located on both sides of the black mulch film. The width of the black mulch film is smaller than the width of the white mulch film.

[0014] As can be seen from the above technical solution, compared with the prior art, this utility model discloses an integrated machine for laying double-layer mulch film and drip irrigation tape. When the machine moves in the field, the black mulch film is laid in the center of the vegetable bed. This black mulch film inhibits weed growth in that area, preventing weeds from competing with crops. The white mulch film is laid on top of the black mulch film and covers the entire vegetable bed, including the black mulch film covering the sides and middle of the crops. The white mulch film lowers the soil surface temperature, preventing crop seeds from being burned by high temperatures. It also helps maintain soil moisture and promotes seed germination. Simultaneously, the drip irrigation tape is laid. Specifically, the drip irrigation tape can be laid between two rows of crops and pressed under the white mulch film, thus achieving water conservation and eliminating the need for manual watering. Furthermore, during laying, the pressing shaft assembly rolls the black and white mulch film and drip irrigation tape to ensure the mulch film is laid flat and without wrinkles or looseness.

[0015] Therefore, this all-in-one machine can lay black and white mulch film and drip irrigation tape completely in one go, greatly improving agricultural efficiency.

[0016] Furthermore, two first limiting discs are sleeved on the white mulch film placement shaft. The two first limiting discs stop at both ends of the white mulch film roll, and both first limiting discs are fixed to the white mulch film placement shaft by first tightening screws.

[0017] The beneficial effects of adopting the above technical solution are: the white mulch film roll can be limited by the two first limiting discs to prevent the white mulch film roll from moving back and forth when rotating; in addition, white mulch film rolls of different widths can be installed according to the requirements of the width of the white mulch film to be laid, which greatly improves the applicability of the integrated machine.

[0018] Furthermore, two second limiting discs are sleeved on the black mulch film placement shaft. The two second limiting discs stop at both ends of the black mulch film roll, and both second limiting discs are fixed to the black mulch film placement shaft by second tightening screws.

[0019] The beneficial effects of adopting the above technical solution are: the black mulch film roll can be limited by two second limiting discs to prevent it from moving back and forth during rotation; in addition, black mulch film rolls of different widths can be installed according to the required width of the black mulch film to be laid, which greatly improves the applicability of the integrated machine.

[0020] Furthermore, the frame is provided with two spaced-apart guide tubes, and the two drip irrigation tapes pass through the corresponding guide tubes and extend to the bottom of the pressure film shaft assembly.

[0021] The beneficial effects of adopting the above technical solution are: the guide tube can guide the laying of drip irrigation tape, ensuring that the drip irrigation tape can be laid between two rows of crops.

[0022] Furthermore, the pressure shaft assembly includes:

[0023] Two height adjustment rods are provided, which are respectively inserted into two guide cylinders on the frame. The height adjustment rods are provided with multiple fixing screw holes vertically.

[0024] Two adjusting bolts are provided, which pass through the guide cylinder and are screwed into the corresponding fixing screw holes for fixation.

[0025] The pressure film shaft has two ends that are rotatably connected to the bottom of the two height adjustment rods. The white mulch film, the black mulch film, and the drip irrigation tape are all pressed against the bottom of the pressure film shaft.

[0026] The beneficial effects of adopting the above technical solution are: the height of the pressing shaft can be adjusted appropriately according to the elevation of the covered area. For example, when arched ridge covering is required, the pressing shaft can be raised to ensure that the mulch film can form a suitable covering height.

[0027] Furthermore, two soil-covering wheel assemblies are mounted on the frame at the rear of the pressing shaft for covering the soil on both sides of the white mulch film.

[0028] The beneficial effect of adopting the above technical solution is that it can compact the edges of the white mulch film to prevent the wind from blowing it away.

[0029] Furthermore, both of the aforementioned soil-covering wheel assemblies include:

[0030] A movable seat, which is slidably connected to a crossbeam on the frame;

[0031] The third tightening screw passes through the movable seat and is in tight contact with the crossbeam.

[0032] A height-adjustable soil-covering screw rod is threadedly connected to a screw hole on the movable base;

[0033] A soil-covering wheel is rotatably connected to the lower part of the height-adjustable soil-covering screw.

[0034] The beneficial effects of adopting the above technical solution are: the position of the movable seat on the crossbeam can be adjusted according to the width of the white mulch film, thereby enabling the covering wheels on both sides to perform soil covering and compaction operations on the edges of the current white mulch film. In addition, the height of the covering wheels can be adjusted by the height-adjustable covering screw, thereby adjusting the amount of soil covering the white mulch film.

[0035] Furthermore, limit locking bolts are screwed onto the height-adjustable soil-covering screw at both the top and bottom positions of the movable seat.

[0036] The beneficial effect of adopting the above technical solution is that it locks the position of the height-adjustable soil-covering screw, preventing the soil-covering wheel from changing its height arbitrarily.

[0037] Furthermore, the frame is equipped with casters.

[0038] The beneficial effect of adopting the above technical solution is that it facilitates the movement of the all-in-one machine.

[0039] Furthermore, the outer edge of the movable wheel is a walking toothed surface that facilitates walking.

[0040] The beneficial effect of adopting the above technical solution is that it facilitates the movement of the integrated machine in the field.

[0041] This invention utilizes a combination of two layers of mulch film (an upper white mulch film and a lower black mulch film) to effectively achieve multiple benefits including temperature regulation, moisture retention, and weed control. The following are specific details:

[0042] 1. Temperature regulation

[0043] The function of the upper white mulch film:

[0044] Reflecting sunlight: White mulch has a high reflectivity, which can reflect most of the sunlight, reduce the direct radiant heat on the ground surface, and thus lower the ground surface temperature.

[0045] Preventing overheating: In hot weather, white mulch can effectively reduce the problem of excessively high ground temperature and protect crops from heat stress.

[0046] Nighttime heat preservation: White mulch can reduce the loss of heat from the ground surface at night, maintain a relatively high temperature, and help stabilize the temperature difference between day and night.

[0047] The function of the lower layer of black mulch film:

[0048] Heat absorption: The black mulch absorbs sunlight, mainly acting on the inner layer of the root zone, which helps to maintain stable soil temperature.

[0049] Heat is released at night: The heat absorbed during the day is gradually released at night, helping to maintain the temperature around the roots and prevent a sudden drop in temperature at night.

[0050] Temperature balance: Under the protection of the white mulch, the black mulch will not get too hot during the day, but it can effectively absorb and balance the temperature of the root zone, promoting the healthy growth of crop roots.

[0051] 2. Moisturizing effect

[0052] The function of the upper white mulch film:

[0053] Reduce evaporation: White plastic film covering crops reduces direct sunlight exposure on the soil surface, thereby reducing soil moisture evaporation.

[0054] Maintaining humidity: White mulch can maintain the humidity of the ground surface and reduce water loss, especially in dry or hot climates.

[0055] The function of the lower layer of black mulch film:

[0056] To prevent water loss: Black mulch is placed on the soil surface to prevent water from evaporating directly into the air and to keep the soil in the root zone moist.

[0057] Preventing runoff: Black mulch can also prevent the loss of irrigation or rainwater runoff, ensuring that more water penetrates into the root zone and improving water use efficiency.

[0058] 3. Weed control effect

[0059] The function of the lower layer of black mulch film:

[0060] Blocking light: Black mulch is opaque and can block sunlight from reaching the soil surface, thereby inhibiting the photosynthesis of weeds and preventing weed growth.

[0061] Reduced competition from weeds: Because black mulch effectively inhibits the growth of weeds, it reduces competition for nutrients and water between weeds and crops, thereby improving the crop's growing environment. Attached Figure Description

[0067] 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.

[0068] like Figures 1-4 As shown, this utility model embodiment discloses an integrated machine for laying double-layer mulch film and drip irrigation tape, comprising:

[0069] Rack 1;

[0070] Drip tape mounting shaft 2 is mounted on frame 1, and two drip tape rolls 3 are fitted on drip tape mounting shaft 2;

[0071] White mulch film placement shaft 4 is installed on the frame 1 and located on one side of the drip irrigation tape placement shaft 2. White mulch film roll 5 is sleeved on the white mulch film placement shaft 4.

[0072] Black mulch film placement shaft 6 is installed on the frame 1 and is located on the other side of drip irrigation tape placement shaft 2. Black mulch film roll 7 is sleeved on the black mulch film placement shaft 6.

[0073] The pressing shaft assembly 8 is installed on the frame 1 and located below the white mulch film placement shaft 4. The white mulch film 51 on the white mulch film roll 5, the black mulch film 71 on the black mulch film roll 7, and the drip irrigation tape 31 on the drip irrigation tape roll 3 are all pressed under the pressing shaft assembly 8.

[0074] The white plastic film 51 is laid on top of the black plastic film 71 and the two drip irrigation tapes 31. The two drip irrigation tapes 31 are located on both sides of the black plastic film 71. The width of the black plastic film 71 is smaller than the width of the white plastic film 51.

[0075] In some embodiments, to prevent the white and black plastic film rolls from moving back and forth during installation, two first limiting discs 9 are fitted onto the white plastic film installation shaft 4. These first limiting discs 9 stop at both ends of the white plastic film roll 5, and are fixed to the white plastic film installation shaft 4 by first tightening screws 10. Two second limiting discs 11 are fitted onto the black plastic film installation shaft 6. These two second limiting discs 11 stop at both ends of the black plastic film roll 7, and are fixed to the black plastic film installation shaft 6 by second tightening screws 12.

[0076] The first tightening screw 10, by tightening against the white mulch film installation shaft, fixes the position of the first limiting disc 9. The second tightening screw 12, by tightening against the black mulch film installation shaft, fixes the position of the second limiting disc 11. Thus, the two first limiting discs 9 limit the white mulch film roll, and the two second limiting discs 11 limit the black mulch film roll, effectively preventing the white and black mulch film rolls from shifting back and forth during installation, ensuring the straightness of the mulch film installation.

[0077] The frame 1 is provided with two spaced guide tubes 13, and two drip irrigation tapes 31 pass through the corresponding guide tubes 13 and extend to the bottom of the pressure film shaft assembly 8.

[0078] The pressure shaft assembly 8 includes:

[0079] There are two height adjustment rods 81, which are respectively inserted into two guide cylinders 101 on the frame 1. Multiple fixing screw holes 811 are vertically opened on the height adjustment rods 81.

[0080] Two adjusting bolts 82 are provided, which pass through the guide cylinder 101 and are screwed into the corresponding fixing screw holes 811 for fixation.

[0081] The pressing shaft 83 has two ends that are rotatably connected to the bottom of the two height adjustment rods 81. The white mulch film 51, the black mulch film 71, and the drip irrigation tape 31 are all pressed under the pressing shaft 83.

[0082] Two soil covering wheel assemblies 14 are installed on the frame 1 at the rear of the pressing shaft 83 for covering soil on both sides of the white mulch film 51.

[0083] In specific implementation, both soil covering wheel assemblies 14 include:

[0084] The movable base 141 is slidably connected to the crossbeam 102 on the frame 1;

[0085] The third tightening screw 142 passes through the movable seat 141 and is in tight contact with the crossbeam 102.

[0086] The height-adjustable soil-covering screw 143 is threadedly connected to the screw hole on the movable seat 141;

[0087] The covering wheel 144 is rotatably connected to the lower part of the height-adjustable covering screw 143.

[0088] Limit locking bolts 145 are screwed onto the height-adjustable soil-covering screw 143 at both the top and bottom positions of the movable base 141.

[0089] The frame 1 is equipped with casters 15. The outer edge of the casters 15 is a walking toothed surface 151 to facilitate movement.

[0090] The upper layer of the mulch film in this invention is white, primarily used to reflect sunlight, reduce soil surface temperature, and prevent seeds from being burned by high temperatures. Simultaneously, the white mulch film has excellent moisture retention properties, helping to maintain soil moisture and promote seed germination.

[0091] Underlying mulch: Black mulch is used primarily to suppress weed growth. The black mulch blocks sunlight, preventing weed growth and thus reducing competition from weeds for crops.

[0092] Drip irrigation tape: The drip irrigation tape is laid during the process of laying the mulch film.

[0093] Example:

[0094] To address the potential high-temperature issues when planting lettuce in high-altitude areas during June, the following double-layer mulch film arrangement is adopted: Figure 4 As shown:

[0095] (1) The vegetable bed is 1.4 meters wide: two rows of lettuce are planted on both sides, with a row spacing of 30cm, so that each row of lettuce has enough growing space with the edge and adjacent rows.

[0096] (2) Lay black mulch in the middle 15cm: Lay black mulch in the middle of the vegetable bed, covering an area 15cm wide.

[0097] (3) Then lay a 1.4-meter-wide transparent white mulch film on top: cover the entire vegetable bed, including the black mulch film on both sides and in the middle where lettuce is planted. Mainly used for heat preservation and humidity maintenance: the transparent mulch film helps to keep the soil warm, maintain soil moisture, and prevent excessive water evaporation. It can also improve photosynthesis: the transparent mulch film allows sunlight to pass through, ensuring that lettuce can receive sufficient light, promoting photosynthesis and growth.

[0098] Overall technical effect:

[0099] (1) Significant temperature regulation effect: The upper white mulch reflects sunlight, reducing soil surface temperature and preventing seeds from being burned by high temperatures. The lower black mulch inhibits weed growth, keeps the soil clean, and helps crops grow healthily. The combined use of the double-layer mulch can provide a more stable soil temperature in high-altitude areas, which is conducive to the germination and growth of late-season lettuce.

[0100] (2) Good moisture retention: The upper white mulch effectively retains moisture, reduces water evaporation, ensures the soil maintains suitable humidity, and promotes seed germination and seedling growth. Double-layer mulch can better maintain soil moisture, reduce irrigation frequency, and save water resources.

[0101] (3) Significant weed control effect: The lower layer of black mulch blocks sunlight, prevents weed growth, and reduces competition for nutrients and water from crops. By inhibiting weed growth, it reduces the workload of farmers in weeding and lowers labor costs.

[0102] (4) Easy to operate and efficient: The double-film laying machine can lay two layers of mulch film at one time, which greatly improves work efficiency. The adjustable width design allows farmers to flexibly purchase and place mulch film according to actual needs, adapting to the needs of different plots and crops.

[0103] (5) Enhance seedling emergence rate and crop yield: Through effective temperature regulation, moisture retention and weeding, the double film laying machine helps to improve the seedling emergence rate and overall yield of late lettuce, thereby increasing farmers' economic benefits.

[0104] (6) The height of the pressing shaft can be adjusted to facilitate the laying of mulch film in arched and flat terrain, ensuring that the mulch film provides coverage and protection in the crop growth space.

[0105] This utility model's integrated machine solves the technical challenges of temperature control, moisture retention, and weed control in late-season lettuce cultivation at high altitudes by simultaneously laying two different layers of mulch film and drip irrigation tape. Its flexible mulch film width adjustment design and efficient operation not only improve work efficiency but also significantly improve the crop's growing environment, increasing germination rate and yield, making cultivation in high-altitude areas more efficient and sustainable.
