[0017] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail. This application discloses an agricultural film-laying device. (Refer to...) Figures 1-5An agricultural planting film laying device includes a main rod 1, with two reinforcing rods 3 fixedly connected to one side of the main rod 1. A handle 4 is fixedly connected between one side of the two reinforcing rods 3. An adjusting rod 6 is slidably connected to the inner wall of the main rod 1. A clamping roller 9 is rotatably connected between the opposite sides of the two adjusting rods 6. A film roll 5 is in close contact between the opposite sides of the two clamping rollers 9. A first support plate 7 and a second support plate 8 are respectively provided between the tops of the two adjusting rods 6. A cutting mechanism 2 is provided on one side of the second support plate 8. The cutting mechanism 2 includes a fixed block 206. One side of the fixed block 206 is fixedly connected to one side of the second support plate 8. A guide frame 201 is fixedly connected to one side of the fixed block 206. A cross slider 207 is slidably connected to the inner wall of the guide frame 201. A connecting block 205 is fixedly connected to the top of the cross slider 207. The bottom of the connecting block 205 is movably connected to the top of the guide frame 201. A connecting rod 204 is fixedly connected to one side of the connecting block 205. A support block 203 is fixedly connected to one side of the connecting rod 204. A film cutting circular knife 202 is rotatably connected to one side of the support block 203 via a bearing.

[0018] Reference Figure 3 and Figure 5 The inner walls of the first support plate 7 and the second support plate 8 are slidably connected with sliding rods 12. The bottom of the two sliding rods 12 is fixedly connected to the top of the two adjusting rods 6. The top of the two sliding rods 12 is fixedly connected with limit caps 11. The bottom of the two limit caps 11 contacts the top of the first support plate 7 and the second support plate 8 respectively. By setting the sliding rods 12, adjusting rods 6 and limit caps 11 to work together, the height of the first support plate 7 and the second support plate 8 can be quickly adjusted to flexibly adapt to the needs of mulch film in different locations. Reference Figure 3 and Figure 5 Springs 13 are movably sleeved on the surfaces of the two sliding rods 12. The bottoms of the two springs 13 contact the tops of the two adjusting rods 6, and the tops of the two springs 13 contact the bottoms of the first support plate 7 and the second support plate 8, respectively. By setting the springs 13, the elastic force of the springs can enable the first support plate 7 and the second support plate 8 to automatically reset after movement, thus providing convenience for the next use. Reference Figure 5 An extension rod 14 is fixedly connected to one side of the first support plate 7. One end of the extension rod 14 extends to the inner wall of the first support plate 7 and slides to connect with the inner wall of the second support plate 8. By setting the extension rod 14, the first support plate 7 and the second support plate 8 can be adjusted after adjusting the two adjustment rods 6, thereby improving the stability and firmness of the first support plate 7 and the second support plate 8 after adjustment. Reference Figure 5Guide blocks 15 are fixedly connected to the top and bottom of the extension rod 14. The surface of the guide block 15 is slidably connected to the inner wall of the second support plate 8. By setting the guide block 15, the stability of the extension rod 14 during movement can be significantly improved, and the deviation of the extension rod 14 during movement can be effectively prevented. Reference Figure 3 and Figure 4 The inner wall of the guide frame 201 is provided with a cross groove 10. The inner cavity of the cross groove 10 is slidably connected to the surface of the cross slider 207. By setting the cross groove 10, a stable trajectory can be provided for the movement of the cross slider 207, effectively preventing it from deviating during the movement, thereby ensuring that the accuracy of the mulch film cutting is not affected. Reference Figure 5 The second support plate 8 has guide grooves 16 at both the top and bottom. The inner cavity of the guide groove 16 contacts the surface of the guide block 15. By setting the guide groove 16, a clear trajectory can be provided for the guide block 15 during movement, effectively preventing the guide block 15 from getting stuck during movement, and thus preventing the guide block 15 from being unable to move normally.

[0019] Working principle: When laying the mulch film, first adjust the two adjusting rods 6 to the appropriate positions corresponding to the mulch film roll 5. Then, insert the mulch film roll 5 into the two clamping rollers 9. During the movement of the adjusting rods 6, the first support plate 7 will move, thereby causing the extension rod 14 to slide in the second support plate 8. At the same time, the guide block 15 also slides in the guide groove 16. Adjust the position of the two adjusting rods 6 to clamp the mulch film roll 5, and lock it with the knob to fix the first support plate 7 and the second support plate 8. At this time, the user pulls the handle 4 to drive the reinforcing rod 3 and the adjusting clamping rollers 9, so that the mulch film roll 5 moves and is laid on the ground. After the mulch film is laid, in order to facilitate the cutting of the mulch film end and avoid adhesion and tilting due to improper cutting force and angle, the second support plate needs to be pressed down. 8. The first support plate 7 is moved downwards. During this process, the spring 13 is compressed, and the slide rod 12 drives the limit cap 11 to limit the movement, so that the two slide rods 12 slide in the second support plate 8 and the first support plate 7 respectively. When the second support plate 8 and the first support plate 7 move to the appropriate position, the film cutting round knife 202 contacts and pierces the mulch film. Then, the user moves the connecting block 205, which drives the cross slider 207 to slide in the cross groove 10. At the same time, the connecting block 205 drives the connecting rod 204 and the support block 203 to move, so that the support block 203 drives the film cutting round knife 202 to cut the mulch film. During the movement, the connecting block 205 is subjected to the linear action of the guide frame 201 and the accurate downward pressure of the first support plate 7 and the second support plate 8 to ensure that the end of the mulch film is cut flat and avoids sticking.

[0020] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
