[0002] Mulching refers to a measure of covering the ground surface with agricultural plastic film, which has the effect of reducing the impact of raindrops and preventing erosion and crust formation; it can effectively reduce the evaporation of soil moisture, conserve moisture during droughts and increase moisture after rains, promote crop absorption of water and growth and development, and improve soil moisture utilization efficiency.

[0003] When covering the ground film, a special covering machine is needed. When in use, the ground film is put on the rotating shaft of the equipment, and a part of the ground film is pulled out to cover one end of the ground film with soil, and then the ground film is moved by the covering machine to gradually cover the surface of the land. If the ground film is loose during use, the ground film can be pulled open by pushing the rod to ensure that the ground film is covered flatly.

[0004] However, when used in serpentine fields, a single push rod is still used to prop up the ground film at the turning point, which may cause wrinkles in the ground film with a small turning radius, resulting in a poor covering effect. Therefore, the present application proposes a ground film covering machine with intelligent tension adjustment. Utility Model Content

DETAILED DESCRIPTION

[0018] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0019] Example 1

[0020] like Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6 Figure 4As shown in the figure, a plastic film mulching machine with intelligent tension adjustment proposed by the present utility model includes a frame 1. The frame 1 is arranged in an "L" shape. A detection box 18 is fixedly connected to one side of the frame 1. The detection box 18 can detect whether the plastic film has wrinkles. A connecting plate 2 is fixedly connected to the bottom of the frame 1. A placement shaft 3 is rotatably connected to one side of the connecting plate 2 close to the frame 1. The plastic film can be sleeved outside the placement shaft 3 for fixation and support. Traveling wheels 24 are rotatably connected to both sides of the frame 1. The traveling wheels 24 can move the frame 1. A connecting frame 22 is fixedly connected to one end of the frame 1. There are two groups of connecting frames 22 arranged symmetrically. A handle 23 is fixedly connected to the end of the connecting frame 22 away from the frame 1. The handle 23 can drive the connecting frame 22 and the frame 1 to move by relying on the traveling wheels 24. A hydraulic rod 21 is fixedly connected to one side of the frame 1. A push rod 4 is fixedly connected to the output end of the hydraulic rod 21. The hydraulic rod 21 can drive the push rod 4 to move, thereby stretching the plastic film. Adjusting rods 5 are rotatably connected to both ends of the push rod 4. A fitting groove 10 is opened at a position inside the adjusting rod 5 close to the push rod 4. A dial shaft 6 is fixedly connected to the push rod 4 close to the fitting groove 10. The adjusting rod 5 rotates by relying on the dial shaft 6 outside the push rod 4. A dial block 7 is fixedly connected to the outside of the dial shaft 6. There are multiple dial blocks 7 arranged in a circumferential array. A rotating shaft 12 is fixedly connected to the push rod 4 on the side away from the dial shaft 6 close to the adjusting rod 5. The rotating shaft 12 is rotatably connected inside the adjusting rod 5. The adjusting rod 5 rotates at one end of the push rod 4 by relying on the rotating shaft 12. An installation sleeve 13 is slidably connected to the outside of the adjusting rod 5. The installation sleeve 13 is arranged in a "C" shape. The "C" shape structure of the installation sleeve 13 can move outside the adjusting rod 5. A spring 16 is fixedly connected to one side of the installation sleeve 13. A rubber block 17 is fixedly connected to the side of the spring 16 away from the installation sleeve 13. The spring 16 can push the rubber block 17 to contact the plastic film, thereby stretching the wrinkled position of the plastic film. An installation screw 14 is rotatably connected to the installation sleeve 13 close to the opening. A telescopic rod 15 is fixedly connected to one side of the installation sleeve 13 close to the spring 16. One end of the telescopic rod 15 away from the installation sleeve 13 is fixedly connected to one side of the rubber block 17. The telescopic rod 15 is arranged inside the spring 16. The telescopic rod 15 can assist the spring 16 in stretching. A limiting component is arranged outside the dial block 7. The limiting component can limit the rotation of the dial block 7.

[0021] As Figures 2 - 4As shown, the limit assembly includes a one-way paddle 9, which is arranged in an arc shape and is embedded between the toggle blocks 7. The toggle blocks 7 can rotate along the arc structure of the one-way paddle 9. The one-way paddle 9 is fixedly connected to a positioning sleeve 8 at one end away from the toggle block 7. The positioning sleeve 8 is fixedly connected to an embedding block 11 on the outside. There are four embedding blocks 11 arranged in a circular array. The embedding block 11 is embedded in the embedding groove 10. The position of the one-way paddle 9 can be fixed by embedding the embedding block 11 in the embedding groove 10, thereby ensuring that the toggle shaft 6 and the toggle block 7 can rotate smoothly, and there is resistance when reversing. The detection box 18 is fixedly connected to a connecting line 19 on the outside, and the connecting line 19 is fixedly connected to a control box 20 at one end away from the detection box 18. The control box 20 is fixedly connected to one side of the frame 1, and the control box 20 is connected to the hydraulic rod 21. The control box 20 can transmit the electrical signal of the detection box 18 through the connecting line 19 to operate, so that the hydraulic rod 21 is retracted.

[0022] In this embodiment, when in use, the ground film is installed on the outside of the placement shaft 3 and is supported and fixed on one side of the frame 1 by the connecting plate 2, so that one end of the ground film can be pulled out, the ground film can be passed around the position of the push rod 4, and the ground film can be pulled out from the position of the traveling wheel 24 under the frame 1, and then the pulled-out ground film position is covered with some soil, thereby fixing one end of the ground film. At this time, the handle 23 can be dragged to drive the connecting frame 22 and the frame 1 to move relying on the traveling wheel 24, so that the ground film is gradually covered on the planting position.

[0023] When used in a straight line, the detection box 18 is used to detect whether wrinkles appear at the pulling-out position of the ground film. When wrinkles appear, the detection box 18 will transmit a detection signal to the hydraulic rod 21, so that the hydraulic rod 21 will drive the push rod 4 to move, so that the push rod 4 drives the adjusting rod 5 and the mounting sleeve 13 to push toward the ground film position bypassing the push rod 4, and the mounting sleeve 13 will rely on the telescopic rod 15 and the spring 16 to push the rubber block 17 to contact the ground film, thereby pushing and extending the position where the wrinkles appear, thereby stretching the wrinkled position flat.

[0024] When the equipment is used in a serpentine field, it is necessary to provide a driving force corresponding to the turning position. At this time, an adjustment rod 5 that does not need to be subjected to excessive force will be adjusted. During the adjustment, the positioning sleeve 8, the one-way paddle 9 and the engaging block 11 are taken out from the engaging groove 10, and then the positioning sleeve 8, the one-way paddle 9 and the engaging block 11 are reversed and inserted into the engaging groove 10. In this way, the rubber block 17 will shrink under the force, and the other frame 1 has a supporting effect, so that the ground film with a small turning radius can still be stretched out for laying.

[0025] To ensure that the friction force of the rubber block 17 is within the specified threshold during use, the mounting sleeve 13 can be removed from the outside of the adjusting rod 5 by means of the mounting screw 14, so that the rubber block 17 can be polished or replaced, thereby ensuring that the rubber block 17 is within the specified friction force for laying and use.

[0026] It should be noted that the device uses a detection box 18 to detect the wrinkles of the ground film, and allows the hydraulic rod 21 to drive the push rod 4, so that the adjusting rod 5 drives the rubber block 17 to fit the ground film, so that the wrinkled position of the ground film can be stretched out. At the turning position, the abutment between the toggle block 7 and the one-way paddle 9 controls which adjusting rod 5 is the main force for stretching the ground film, thereby avoiding the problem that a single push rod 4 cannot achieve uniform and flat inner and outer diameters at the turning position, and increases the stretching effect on different positions of the ground film when turning.

[0027] The above-mentioned specific embodiments are only several optional embodiments of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above-mentioned embodiments, those skilled in the art can make various alternative improvements and combinations to the above-mentioned specific embodiments.
