It should be noted that the transmission ratio of the first transmission wheel 15 and the second transmission wheel 21 should be controlled so that the drill bit mechanism 25 drills a hole once after the walking wheel 13 moves a predetermined distance (transplanting plant distance).

[0044] In an example, the drill bit mechanism 25 comprises an upper disc body 251, a lower disc body 252, a drill bit shaft 253, a film cutting piece 254, a soil turning piece 255, a mud blocking cylinder 256, a first spring 257, a first movable rod 258, a second gasoline engine 259, a flexible shaft 260 and a transmission mechanism 261, the upper disc body 251 is fixedly mounted at the bottom of the film breaking rod 24, the lower disc body 252 is connected below the upper disc body 251 through a plurality of fixing rods 265, the diameter of the lower disc body 252 is smaller than that of the upper disc body 251, the drill bit shaft 253 is rotatably mounted on the lower disc body 252, the film cutting piece 254 and the soil turning piece 255 are sequentially mounted on the drill bit shaft 253 from bottom to top, the film cutting piece 254 is two pieces and symmetrically mounted on the drill bit shaft 253, the soil turning piece 255 is a spiral piece, the mud blocking cylinder 256 is connected below the upper disc body 251 through a plurality of springs and the first movable rod 258, the bottom of the first movable rod 258 is fixedly connected to the mud blocking cylinder 256, the top of the first movable rod 258 is movably arranged through the upper disc body 251, and the first spring 257 is sleeved on the first movable rod 258, the mud blocking cylinder 256 surrounds the film cutting piece 254 and the soil turning piece 255, the second gasoline engine 259 is mounted on the vehicle frame 11, and is connected to the transmission mechanism 261 through the flexible shaft 260, the transmission mechanism 261 is connected to the drill bit shaft 253, and the transmission mechanism 261 is a conventional device of the drilling device, for example, a worm and gear transmission, which will not be described here.

[0045] When working, the second gasoline engine 259 transmits power to the drill shaft 253 through the flexible shaft 260 and the transmission mechanism 261. When the crank rocker mechanism 23 drives the drill shaft 253 to drill into the soil, the mud cylinder 256 first presses on the film, then compresses the first spring 257, and the drill shaft 253 continues to drill down, the film cutter cuts the film, and drills a hole in the soil. The soil piece 255 rotates the soil upwards and outwards, and the thrown mud is blocked by the mud cylinder 256 and falls onto the film between the mud cylinder 256 and the soil piece 255, thereby realizing the film covering operation. Thus, through the cooperation of the film cutting piece 254, the soil piece 255, the mud cylinder 256, the first spring 257 and the first movable rod 258, the device can not only punch holes while covering the film, but also rotate the soil produced by punching and cover it on the film around the punched hole.

[0046] In an example, second movable rods 262 are installed on both sides of the bottom of the vertical frame 113, the second movable rods 262 can move up and down relative to the vertical frame 113, the bottom of the second movable rod 262 is provided with a film pressing roller 263, and a second spring 264 is sleeved on the second movable rod 262. The film pressing roller 263 can be elastically pressed on the film during movement, which can effectively improve the punching effect in cooperation with the fixed film.

[0047] The film covering unit includes a film cylinder frame 31, a film pressing wheel 32 and a soil guiding wheel 33 installed in front of the drill mechanism 25 from front to back under the vehicle frame 11, and the film pressing wheel 32 and the soil guiding wheel 33 are located on both sides of the vehicle frame 11 respectively.

[0048] In an example, the U-shaped frame 114 includes an upper horizontal rod 1141, a lower horizontal rod 1142, a vertical rod 1143 and a middle connecting rod 1144. The upper horizontal rod 1141 is located at the front end of the flat frame 111, the lower horizontal rod 1142 is connected below the upper horizontal rod 1141 through the middle connecting rod 1144, the vertical rod 1143 is connected at both ends of the upper horizontal rod 1141 and the lower horizontal rod 1142, and the traveling wheel 13 is installed on the side surface of the vertical rod 1143. The traveling wheel 13 can be selected as a solid rubber wheel.

[0049] In an example, an adjusting rod 34 is connected to the middle top of the film cylinder frame 31, the adjusting rod 34 can be adjusted up and down and installed on a horizontal rod 35, and the horizontal rod 35 is fixedly connected with the middle connecting rod 1144, so that the fixed position of the adjusting rod 34 can be changed as needed.

[0050] In an example, the adjusting rod 34 is provided with a curved rod 36 extending downwardly to the rear side, and a low end of the curved rod 36 is connected with a roller frame 37, the roller frame 37 is provided with a film pressing roller 38, and arc-shaped rods 39 are arranged on both sides of the roller frame 37, and the film pressing roller 38 is located below the rear side of the film cylinder frame 31. When the film cylinder frame 31 releases the film, the film pressing roller 38 can timely press the film on the ridge, and the arc-shaped rods 39 can also flatten the film on both sides, thereby improving the subsequent film covering and punching effect.

[0051] In an example, the film pressing wheel 32 and the soil guiding wheel 33 are installed on the longitudinal rod 41 through the support 40, a front end of the longitudinal rod 41 is adjustably installed on a longitudinal curved rod 42, and a front end of the longitudinal curved rod 42 is adjustably installed on the lower cross rod 1142, so that the positions of the film pressing wheel 32 and the soil guiding wheel 33 on both sides and in the longitudinal direction can be adjusted as required.

[0052] The working principle of the film covering, fixed-point film breaking and soil covering all-in-one machine is as follows:

[0053] When the film cylinder frame 31 is installed with the film cylinder, the vehicle frame 11 is arranged on one side of the ridge, and the running wheels 13 are located in the ridges on both sides. During the forward movement of the vehicle frame 11 driven by the handrail 112 and the first gasoline engine 12, the film cylinder first releases the film, and then the film pressing wheel 32 and the arc-shaped rods 39 press the film on the ridge. The film on both sides is pressed by the film pressing wheel 32 and is guided by the soil guiding wheel 33 to guide the soil in the ridge to the film to cover and fix the film. Meanwhile, under the power transmission of the first transmission wheel 15, the second transmission wheel 21, the transmission chain 26 and the driving shaft 22, the crank rocker mechanism 23 reciprocates and swings, and when the drill shaft 253 is driven downward to drill into the soil, the mud blocking cylinder 256 is first pressed on the film, and then the first spring 257 is compressed. The drill shaft 253 continues to move downward, the film cutting knife cuts the film, and a hole is drilled in the soil. During the drilling process, the soil piece 255 rotates the soil upward and outward, and the mud blocked by the mud blocking cylinder 256 falls onto the film between the mud blocking cylinder 256 and the soil piece 255, thereby realizing the film covering operation. Finally, the crank rocker mechanism 23 drives the drill shaft 253 out of the soil, and the mud blocking cylinder 256 returns to the initial position under the action of gravity and the first spring 257, thereby preparing for the next drilling.

[0054] The above-described embodiments only express several implementation manners of the present application, and the description is relatively specific and detailed, but it cannot be understood as a limitation on the patent scope of the present application. It should be noted that, for ordinary skilled persons in the art, without departing from the concept of the present application, several modifications and improvements can be made, which all belong to the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the appended claims.
