Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0047] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0048] See also Figure 1-Figure 8 The embodiment of the present invention provides a mulch film laying device for agricultural planting, comprising a mulch film laying frame 1, on which a traction bracket 2 is fixedly mounted, and further comprising:

[0049] A detachable support rod 26, wherein the detachable support rod 26 is installed on the mulch film laying frame 1, and a mulch film reel 22 is also sleeved on the detachable support rod 26;

[0050] and a ground film laying mechanism, the ground film laying mechanism is connected to the ground film laying frame 1 and installed close to the ground film reel 22, wherein the ground film laying mechanism includes a position adjustment component, a film pressing wheel 8 and a covering plate 9;

[0051] The position adjustment component is connected to the ground film laying frame 1, and the film pressing wheel 8 and the soil covering plate 9 are both connected to the position adjustment component, and the soil covering plate 9 and the film pressing wheel 8 are arranged close to the ground film reel 22 in sequence.

[0052] When laying ground film in a designated area, first, the entire laying equipment can be connected to an external traction device through a traction bracket 2, and the traction device drives the entire laying equipment forward, and then the ground film to be laid is fixed on the ground film reel 22, wherein the ground film reel 22 can rotate on the detachable support rod 26, so that when the laying equipment moves forward, the ground film wound on the ground film reel 22 is gradually loosened and covered on the ground. In addition, the detachable support rod 26 can be removed from the ground film laying frame 1 to facilitate replacement of ground films of the same or different sizes. In addition, a controller 14 is also fixedly installed on the ground film laying frame 1 for controlling the ground film laying mechanism. Electrical equipment, during the forward movement of the overall paving equipment, the two film pressing wheels 8 will press on the two edges of the ground film that has just fallen off the ground film reel 22, so that the ground film can be evenly covered on the designated ground. In addition, during the forward movement of the equipment, the covering plate 9 will cover the soil on both sides of the ground film on the edge of the ground film to fix the ground film laid on the ground. In addition, through the set position adjustment component, ground films of different widths can be laid, which improves the practicability and flexibility of the equipment, is simple to operate, can save manpower, and improve the work efficiency of the laying operation. In addition, it can also ensure the uniformity and quality of the laying, providing convenience for the staff.

[0053] In one embodiment of the present invention, see Figure 1-Figure 8 , further comprising: a support plate 12, one end of which is fixedly connected to the ground film laying frame 1;

[0054] A detection guide roller 13, wherein the detection guide roller 13 is rotatably connected to the other end of the support plate 12, and the height of the detection guide roller 13 is lower than the height of the ground film reel 22;

[0055] And a toggle adjustment component, the toggle adjustment component is connected to the support plate 12 and is detachably connected to the ground film reel 22, and the toggle adjustment component is also electrically connected to the detection guide roller 13 and the position adjustment component respectively.

[0056] The toggle adjustment component comprises:

[0057] A telescopic cylinder 24, wherein the telescopic cylinder 24 is fixedly mounted on the support plate 12 and is electrically connected to the detection guide roller 13 and the position adjustment assembly respectively;

[0058] A push-pull rod 25, which is inserted into the support plate 12 and is slidably connected to the support plate 12, and is also fixedly connected to the output end of the telescopic cylinder 24;

[0059] And an adjusting fork tine 23 , one end of which is fixedly connected to the push-pull rod 25 , and the other end of which is inserted into the detachable support rod 26 and detachably connected to the ground film reel 22 .

[0060] During the laying process of the ground film, under the guiding action of the detection guide roller 13, the ground film can be made close to the area where it needs to be laid (the ground film goes from the top of the ground film reel 22 downward around the bottom of the detection guide roller 13, so that the ground film can be made close to the ground). In addition, a plurality of detection wheels can be provided on the detection guide roller 13. By detecting the rotation of the wheels, it can be determined whether the laying position of the ground film is offset. For example, the detection wheels located on both sides of the detection guide roller 13, when a certain detection wheel on one side is not driven by the ground film to rotate, it proves that the ground film on this side may be offset to the other side. At this time, starting the telescopic cylinder 24 can push or pull the push-pull rod 25 to slide on the support plate 12, and drive the adjusting fork 23 to push or pull the ground film reel 22 to slide on the detachable support rod 26 (fine-tune) to correct the loose ground film on the ground film reel 22, thereby ensuring that the ground film is accurately laid at the specified position.

[0061] In one embodiment of the present invention, see Figure 1-Figure 8 , the position adjustment component comprises:

[0062] A regulating support plate 3, wherein the regulating support plate 3 is fixedly connected to the ground film laying frame 1, and a guide regulating groove 4 and a sliding control groove 5 are formed on the regulating support plate 3;

[0063] A second connecting plate 27, the second connecting plate 27 is rotatably connected to the film pressing wheel 8, and a lifting card plate 19 is fixedly installed on the second connecting plate 27, and a pressure limiting sliding column 10 is fixedly installed on the lifting card plate 19, and the pressure limiting sliding column 10 is inserted in the guide adjustment groove 4 and is slidably connected to the guide adjustment groove 4;

[0064] And an adjusting driving unit, wherein the adjusting driving unit is respectively connected to the ground film laying frame 1 and the lifting clamping plate 19, and is slidably connected to the sliding control groove 5.

[0065] The adjustment drive unit comprises:

[0066] A driving motor 15, wherein the driving motor 15 is fixedly mounted on the ground film laying frame 1;

[0067] An adjusting screw 17, wherein the adjusting screw 17 is rotatably connected to the ground film laying frame 1, and one end of the adjusting screw 17 is fixedly connected to the output end of the driving motor 15, wherein the threads on both sides of the adjusting screw 17 rotate in opposite directions;

[0068] The threaded sleeve 16 is two in number, and the two threaded sleeves 16 are respectively sleeved on both sides of the adjusting screw 17, and the threaded sleeves 16 are both fixedly mounted with guide slide posts 11, and the two guide slide posts 11 are both inserted into the sliding control groove 5 and are slidably connected with the sliding control groove 5;

[0069] And a movable slide plate 18 , wherein the movable slide plate 18 is fixedly connected to the threaded sleeve 16 , and the movable slide plate 18 is also slidably connected to the lifting clamping plate 19 .

[0070] It also includes: a connecting plate 20, the connecting plate 20 is fixedly connected to the lifting card plate 19, and is fixedly connected to the covering plate 9;

[0071] And an anti-rolling roller 21, the number of the anti-rolling roller 21 is multiple, and the multiple anti-rolling rollers 21 are distributed on the connecting plate 1 20 in an inclined state.

[0072] When replacing mulch films of different widths, it is necessary to adjust the distance between the two mulch pressing wheels 8, otherwise good mulch pressing and soil covering cannot be performed, resulting in poor laying effect. In addition, a wider mulch film requires more soil covering to ensure that both sides of the mulch film are completely covered to achieve the effects of heat preservation, moisture retention and prevention of weed growth, while a narrower mulch film requires less soil covering; at the same time, a wider mulch film requires a larger pressing wheel pressure to ensure that both sides of the mulch film are tightly fitted to the ground to prevent it from being blown up or moved by the wind, while a narrower mulch film may require a smaller pressing wheel pressure to avoid crushing the mulch film or causing it to deform; therefore, starting the drive motor 15 can drive the adjusting screw 17 to rotate. Since the threads on both sides of the adjusting screw 17 rotate in opposite directions, under the cooperation between the threads of the adjusting screw 17 and the threaded sleeve 16, and under the guiding action of the sliding control groove 5 on the guide slide column 11, the two threaded sleeves 16 can be moved toward the middle of the adjusting screw 17. During the movement of the threaded sleeve 16, the movable slide plate 18 can be driven to move synchronously, and the movable slide plate 18 When moving, it will drive the lifting card plate 19 and the film pressing wheel 8 to move synchronously, thereby reducing the distance between the two film pressing wheels 8 to press the film on the ground with a smaller width. In addition, when the two lifting card plates 19 are close to each other, under the guidance of the guide adjustment groove 4 on the pressure limit slide post 10, the lifting card plate 19 can be moved upward on the moving slide plate 18 for a short distance, so that when the two film pressing wheels 8 are close to each other, the distance from the ground will also be increased accordingly by a short distance, thereby reducing the pressure on the ground film with a smaller width. In addition, during the movement of the film pressing wheel 8, the covering plate 9 can be driven to move synchronously, so that the covering plate 9 also increases the distance between the ground and the ground, thereby reducing the amount of soil turned over by the covering plate 9, and then reducing the amount of soil covering the ground film, so as to ensure the smooth progress of the paving operation, improve the practicability and flexibility of the equipment, and through the provision of multiple anti-rolling rollers 21, the edge of the ground film before entering the ground can be lifted up to prevent the edge of the ground film from curling when it is laid on the ground, affecting the covering effect.

[0073] In one embodiment of the present invention, see Figure 1-Figure 8 , further comprising: a loading and unloading slot 6, wherein the loading and unloading slot 6 is provided on the regulating support plate 3 and is connected to the guide regulating slot 4 and the sliding control slot 5;

[0074] A clamping control plate 28, the clamping control plate 28 is inserted into the loading and unloading slot 6 and is slidably connected to the loading and unloading slot 6, and the clamping control plate 28 is also located between the pressure limiting sliding post 10 and the guide sliding post 11 and is slidably connected to the pressure limiting sliding post 10;

[0075] And a clamping control component, which is connected to the guide slide post 11 and is slidably connected to the clamping control plate 28.

[0076] The clamping control assembly comprises:

[0077] An adjusting chamber 30, wherein the adjusting chamber 30 is provided in the guide slide column 11;

[0078] A lifting column 31, wherein the lifting column 31 is inserted into the adjusting chamber 30 and is slidably connected with the guide slide column 11;

[0079] An arc-shaped pressing plate 29, which is fixedly connected to one end of the lifting column 31 and is located outside the guide slide column 11, and is also slidably connected to the clamping control plate 28;

[0080] And a tightening adjustment spring 32, the number of the tightening adjustment springs 32 is multiple, the multiple tightening adjustment springs 32 are all located in the adjustment chamber 30, and the two ends of the tightening adjustment spring 32 are fixedly connected to the adjustment chamber 30 and the lifting column 31 respectively.

[0081] When adjusting the distance between the two film pressing wheels 8, since multiple components are movable parts, the film pressing wheels 8 may shake during operation. Therefore, the clamping control plate 28 is inserted into the loading and unloading slot 6, and under the elastic action of the tightening adjustment spring 32, a thrust can be exerted on the lifting column 31, and the lifting column 31 will push the arc-shaped pressure plate 29 to squeeze the upper end surface of the clamping control plate 28, so that the lower end surface of the clamping control plate 28 squeezes the pressure limiting slide post 10, so that the pressure limiting slide post 10 can be ensured to be in a stable state at any position of the film pressing wheel 8, thereby avoiding the film pressing wheel 8 from shaking during operation. In addition, a heat dissipation port 7 is also provided on the regulating support plate 3, so that The heat generated when the clamping control plate 28 slides in the loading and unloading slot 6 is discharged in time. In addition, the top of the clamping control plate 28 is an inclined structure, and its inclination direction is opposite to the direction of the guide adjustment slot 4. When the guide slide column 11 moves toward the side of the clamping control plate 28, the distance between the two film pressing wheels 8 increases, and the width of the ground film to be laid is also larger. At this time, the pressure of the film pressing wheel 8 on the ground is relatively large. In order to avoid insufficient pressure or shaking when the film pressing wheel 8 is working in a state of high pressure, at this time, since the top of the clamping control plate 28 is an inclined structure, the pressure of the arc-shaped pressure plate 29 on the clamping control plate 28 will also increase, thereby ensuring the smooth progress of the laying work. No further details will be given here.
