Description

Technical Field

[0001] This utility model belongs to the field of mulch film covering technology, specifically relating to a mulch film covering device for planting. Background Technology

[0002] In modern agriculture, mulch is often laid on the ridges before planting. This is because mulch can enhance the soil's water and fertilizer retention capacity, improve nutrient utilization, keep the soil loose, prevent soil compaction caused by excessive watering, and prevent pests from attacking crops and diseases caused by certain microorganisms.

[0003] Chinese patent document CN111480502A discloses a film covering device with an automatic soil pressing function on top of the film after agricultural planting. The front end of the front frame is connected to the tractor, and the left and right ends of the front frame are symmetrically connected to a mounting side frame. There are four disc plows, and the four disc plows are connected to the left and right ends of the front frame through two mounting side frames. The device uses soil pressing pipes to roll on top of the film roller, and dumps the soil stored in the two soil pressing pipes into the top of the film roller in an alternating pattern through the soil discharge pipe, so that the spacing between the soil piles discharged from the soil pressing pipes is maintained at 30 centimeters, thus maintaining the uniformity of soil pressing on top of the film.

[0004] However, the above-mentioned film covering device still has the following shortcomings during use:

[0005] The aforementioned mulching device can only be used on mulch films with larger widths. It cannot select the soil covering area according to the width of the ridges and mulch films, nor can it adjust the wheel spacing, soil-pulling structure, and mulch film roll clamping structure. Different sizes of mulching devices need to be selected for different ridge and mulch film widths, which brings trouble to the mulching work and reduces mulching efficiency. Summary of the Invention

[0006] To address the problems mentioned in the background section, this invention provides a planting mulch film covering device. The device adjusts the drive wheels and the soil-lifting plow via an adjustment mechanism to accommodate different ridge widths. The mulch film covering mechanism uses a drive structure to adjust the clamping rods, clamping mulch film rolls of varying widths. The mulch film rollers press the film down into contact with the soil, ensuring a close fit. The soil-lifting plow, with its curved structure, pushes soil from both sides of the mulch film onto it, compacting the film. This simplifies the mulching process and improves efficiency.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a planting mulch film covering device, including a vehicle body, an installation adjustment groove is provided inside the vehicle body, an adjustment mechanism is slidably installed inside the installation adjustment groove, drive wheels are connected to both sides of the adjustment mechanism extending out of the vehicle body, a film covering mechanism is installed on the front end of the vehicle body, a width-adjustable clamping arm is driven and connected to the film covering mechanism through a second drive structure, a second electric telescopic rod is connected to the bottom end of the film covering mechanism, and a film covering roller is connected to the second electric telescopic rod through a bracket.

[0008] As a preferred embodiment, the adjustment mechanism includes an E-shaped adjustment frame and a first bidirectional reciprocating lead screw. The first bidirectional reciprocating lead screw is installed in the middle of the installation adjustment groove. The E-shaped adjustment frame is slidably mounted on the first bidirectional reciprocating lead screw via a first lead screw slider. The bottom of the E-shaped adjustment frame slides on a limiting groove at the bottom of the installation adjustment groove via a limiting slider. The E-shaped adjustment frame includes a wheel adjustment arm and a soil-digging plow adjustment arm. The drive wheel is installed at the bottom of the outer end of the wheel adjustment arm. A first electric telescopic rod is installed at the bottom of the soil-digging plow adjustment arm. A soil-digging plow is installed at the telescopic end of the bottom of the first electric telescopic rod. A first lead screw motor that is driven and connected to the first bidirectional reciprocating lead screw is installed inside the vehicle body.

[0009] As a preferred embodiment, the second drive structure includes a second bidirectional reciprocating lead screw, which is installed in the moving groove of the film covering mechanism. Both ends of the second bidirectional reciprocating lead screw are connected to one end of the clamping arm via a second lead screw slider. A clamping rod is provided on the inner side of the other end of the clamping arm. One end of the second bidirectional reciprocating lead screw passes through the film covering mechanism and is connected to a second lead screw motor. The clamping rod clamps the film roll.

[0010] As a preferred embodiment, the clamping arm is driven by a second lead screw motor to move in opposite directions in the horizontal direction via a second lead screw slider.

[0011] As a preferred embodiment, the drive wheels and the soil-digging plow are driven by a first lead screw motor to move horizontally in opposite directions on both sides of the vehicle body via a first lead screw slider.

[0012] As a preferred embodiment, a push rod is connected to the rear end of the vehicle body.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention adjusts the drive wheels and the soil-lifting plow according to the width of the ridges using an adjustment mechanism to adapt to the required ridge width. The mulching mechanism uses an adjustable clamping rod on its drive structure to hold mulch rolls of different widths, and the mulching rollers press the mulch into contact with the planting soil, ensuring complete adhesion and coverage of the soil surface. The soil-lifting plow, with its curved structure, pushes the soil from both sides of the mulch onto it, thus compacting the sides. This increases the stability of the mulch after installation, preventing it from being blown away by the wind. It facilitates the mulching process and improves mulching efficiency.

[0028] like Figure 2-3 As shown, in this embodiment, the adjustment mechanism 2 includes an E-shaped adjustment frame and a first bidirectional reciprocating lead screw 26. The first bidirectional reciprocating lead screw 26 is installed in the middle of the installation adjustment groove 12. The E-shaped adjustment frame is slidably mounted on the first bidirectional reciprocating lead screw 26 via a first lead screw slider. The bottom of the E-shaped adjustment frame slides on the limiting slide groove 13 at the bottom of the installation adjustment groove 12 via a limiting slider 24. The E-shaped adjustment frame includes a wheel adjustment arm 22 and a soil plow adjustment arm 23. The drive wheel 21 is installed at the bottom of the outer end of the wheel adjustment arm 22. A first electric telescopic rod 4 is installed at the bottom of the soil plow adjustment arm 23. The telescopic end of the first electric telescopic rod 4 is installed with... The vehicle body 1 is equipped with a soil-removing plow 5 and a first screw motor 25 connected to the first bidirectional reciprocating screw 26. The drive wheels 21 and the soil-removing plow 5 are driven by the first screw motor 25 to move horizontally in opposite directions on both sides of the vehicle body 1 via the first screw slider. The first screw motor 25 is controlled to start the first bidirectional reciprocating screw 26. The first bidirectional reciprocating screw 26 drives the wheel adjustment arms 22 and the soil-removing plow adjustment arms 23 on both sides to slide synchronously in opposite directions, thereby facilitating the adjustment of the wheel spacing and soil-removing structure to adapt to the required width of the ridge.

[0029] like Figure 3-4As shown, in this embodiment, the second driving structure includes a second bidirectional reciprocating lead screw 33, which is installed in the moving groove of the film covering mechanism 3. Both ends of the second bidirectional reciprocating lead screw 33 are connected to one end of the clamping arm 32 via second lead screw sliders 34. A clamping rod 31 is provided on the inner side of the other end of the clamping arm 32. One end of the second bidirectional reciprocating lead screw 33 extends out of the film covering mechanism 3 and is connected to a second lead screw motor 35. The clamping rod 31 clamps the mulch film roll 8. The clamping arm 32 is driven by the second lead screw motor 35. The second bidirectional reciprocating screw 33 is driven by the second screw slider 34 to move in opposite directions in the horizontal direction; according to the width of the mulch film, the second screw motor 35 is controlled to drive the second bidirectional reciprocating screw 33 to run. The second bidirectional reciprocating screw 33 drives the clamping arm 32 to move in opposite directions in the horizontal direction via the second screw slider 34, thereby facilitating the adjustment of the clamping rod 31 to achieve clamping and support of mulch film rolls of different widths; the appropriate mulch film roll 8 is clamped and supported on the clamping arm 32 by the clamping rod 31.

[0030] In this embodiment, a push rod 11 is connected to the rear end of the vehicle body 1.

[0031] In addition, the vehicle body 1 is equipped with a power supply and switch control box for powering the first lead screw motor 25, the second lead screw motor 35, the first electric telescopic rod 4, and the second electric telescopic rod 6.

[0032] The working principle and usage process of this utility model: When using this utility model, firstly, according to the width of the ridge, the first lead screw motor 25 is started to drive the first bidirectional reciprocating lead screw 26 to run. The first bidirectional reciprocating lead screw 26 drives the wheel adjustment arms 22 and the soil-pulling plow adjustment arms 23 on both sides to slide synchronously in opposite directions, thereby facilitating the adjustment of the wheel spacing and soil-pulling structure to adapt to the current required width of the ridge.

[0033] Based on the width of the mulch film, the second lead screw motor 35 is started to drive the second bidirectional reciprocating lead screw 33 to run. The second bidirectional reciprocating lead screw 33 drives the clamping arm 32 to move in opposite directions in the horizontal direction via the second lead screw slider 34, thereby facilitating the adjustment of the clamping rod 31 to achieve clamping and support of mulch film rolls of different widths. The appropriate mulch film roll 8 is clamped and supported on the clamping arm 32 by the clamping rod 31.

[0034] During the mulching process, the drive wheels 21 propel the vehicle body 1 forward along the ridges. First, a section of mulch film is pulled out from the mulch film roll 8 and laid on the planting soil along the lower surface of the mulching roller 7. At this time, the second electric telescopic rod 6 is activated to drive the mulching roller 7 to press the mulch film down into contact with the planting soil, ensuring that the mulch film fully adheres to the soil surface. Then, the extension and retraction of the first electric telescopic rod 4 is controlled to adjust the turning depth of the soil-moving plow 5 to meet the needs of various situations. As the soil-moving plow 5 moves forward with the vehicle body 1, it uses its curved structure to push the soil on both sides of the mulch film onto the mulch film, thereby compacting both sides of the mulch film. This increases the stability of the mulch film after laying, thus preventing the mulch film from being blown away by the wind. This brings convenience to the mulching work and improves the efficiency of mulching.
