[0016] See also Figure 1-3 The utility model provides a technical solution: including a connecting device 100 and a trenching device 200.

[0017] In the technical solution, an agricultural film laying device for farmland, the connecting device 100 includes a connecting rod 110, a first connecting frame 120 and a second connecting frame 130, the first connecting frame 120 and the second connecting frame 130 are welded to the bottom of the connecting rod 110, a roller 121 is placed in the inner cavity of the first connecting frame 120, a film is wound around the outside of the roller 121, and a roller 131 is installed at the bottom of the second connecting frame 130 through a rotating shaft;

[0018] In this technical solution, the connecting rod 110, the first connecting frame 120 and the second connecting frame 130 are used to provide installation points for the installation of various parts, and the connecting rod 110 is connected to an external power mechanism and moves, the roller 121 is used to wrap the film, and as it moves, the film can be spread flat on the ground, and the roller 131 rolls in the groove to press the side of the film into the bottom of the groove.

[0019] The ditching device 200 includes a fourth connecting frame 210, a motor 220 and a connecting shaft 230. The fourth connecting frame 210 is welded to the bottom of the connecting rod 110. The motor 220 is fixed to the bottom surface of the top of the fourth connecting frame 210 through a mounting rod. The mounting rod is an L-shaped structure. The top of the mounting rod is welded to the fourth connecting frame 210. The motor 220 is fixedly connected to the mounting rod through bolts. The driving end of the motor 220 is keyed to a first gear 221. Both ends of the connecting shaft 230 are rotatably connected to the bottom of the fourth connecting frame 210 through bearings. Both ends of the connecting shaft 230 are respectively clamped with a soil-breaking roller 232. The outer wall of the soil-breaking roller 232 is annularly welded with multiple soil-breaking rods. The outer wall of the connecting shaft 230 is clamped with a second gear 231, and the second gear 231 is meshed and connected with the first gear 221.

[0020] In this technical solution, the fourth connecting frame 210 is used to provide installation points for the installation of various parts, the motor 220 and the first gear 221 are used to drive the rotation of the connecting shaft 230, the connecting shaft 230, the second gear 231 and the breaking roller 232 rotate synchronously, so that the breaking rod stirs and crushes the ground, and the direction in which the soil is thrown out is the same as the forward direction of the device, leaving a groove on the ground.

[0021] In some technical solutions, reference Figure 1-2 A third connecting frame 140 is welded to the bottom of the connecting rod 110, and the third connecting frame 140 is located between the first connecting frame 120 and the fourth connecting frame 210. The bottoms of both ends of the third connecting frame 140 are respectively connected to a compaction frame 141 through a rotating shaft, and a torsion spring is installed between the rotating shaft and the end of the third connecting frame 140. An electric push rod 142 is installed on the outer wall of the third connecting frame 140 through a cross plate. The cross plate is welded to the third connecting frame 140, and the fixed end of the electric push rod 142 is fixed to the cross plate by bolts, and the movable end of the electric push rod 142 can contact the top of the compaction frame 141.

[0022] In this technical solution, the compaction frame 141 has the characteristics of a narrow bottom and a wide top. The electric push rod 142 can control the direction of rotation of the compaction frame 141 on the rotating axis. When the electric push rod 142 is separated from the compaction frame 141, the compaction frame 141 rotates under the action of the torsion spring, and an angle is formed between the bottom of the compaction frame 141 and the gully. When the electric push rod 142 contacts the compaction frame 141, the bottom of the compaction frame 141 can be kept parallel to the gully, and the soft soil on the inner wall of the gully can be squeezed.

[0023] In some technical solutions, reference Figure 1 and Figure 3 A clamping hole 123 is opened inside the first connecting frame 120, and the end of the roller 121 is clamped in the clamping hole 123. A clamping block 122 and a welded limiting plate 124 are inserted into the outer wall of the first connecting frame 120. The clamping block 122 can extend into the clamping hole 123, and the limiting plate 124 can contact the end of the roller 121.

[0024] In this technical solution, the combined use of the clamping block 122 and the limiting plate 124 can firmly restrict the end of the roller 121 in the clamping hole 123, thereby preventing the roller 121 from horizontally moving out of the clamping hole 123 during use, or the roller 121 from being pulled out of the clamping hole 123, so that the roller 121 can discharge materials stably.

[0025] In some technical solutions, reference Figure 1 and Figure 3 The outer side walls at both ends of the second connecting frame 130 are respectively welded with a bulldozer plate 132 that is distributed in an inclined manner, and the two bulldozer plates 132 are distributed in an eight-shaped shape.

[0026] In this technical solution, the bulldozer plate 132 pushes the soil on the top of the gully side to make it roll into the gully to increase the strength of compaction on the film side.

[0027] Working principle: Connect the connecting rod 110 to the external driving mechanism, and connect the electric push rod 142 and the motor 220 to the external control device and power supply. Before laying the film, install the roller 121 with the film wrapped around it at the bottom of the first connecting frame 120, and use the clamping block 122 and the limit plate 124 to complete the positioning and clamping, and fix the end of the film with soil. After starting the external driving mechanism, drive the connecting rod 110 to move. At this time, the motor 220 drives the connecting shaft through the first gear 221 and the second gear 231. 230 rotates, at this time, the soil-breaking roller 232 leaves a groove on the ground, and the electric push rod 142 intermittently separates and contacts with the compacting frame 141 to compact the inner wall of the groove. At this time, the roller 121 rotates under the pull of the film, so that the film is spread flat on the soil surface, and the roller 131 presses the side of the film into the bottom of the groove when rolling in the groove, and the soil on the top of the side of the groove slides into the groove under the push of the bulldozer 132, completing the compaction of the side of the film, thereby effectively improving the laying efficiency of the film.
