After that, each time the crank shaft 302 rotates one circle, it will form abutment with the upper surface of the pressure frame 304, and then drive the pressure frame 304 to slide downward. The downward sliding of the pressure frame 304 drives the linkage operation of the digging device 306 and the quantitative delivery device 307.

[0021] The digging device 306 includes a hollow rotating shaft 3061, the top of the hollow rotating shaft 3061 is rotatably connected to the pressing frame 304, the surface of the hollow rotating shaft 3061 is provided with a spiral sheet 3062, the interior of the box body 301 is provided with a spiral groove 3063, the interior of the spiral groove 3063 is slidably connected with a sliding pin 3064, and the sliding pin 3064 is fixed on the surface of the hollow rotating shaft 3061.

When the pressing frame 304 is pressed and slid downward, the sliding frame 3079 will also be driven to move downward synchronously, and the sliding extrusion of the inclined surface will drive the sliding plate 3074 to slide inside the square tube 3073. As the sliding plate 3074 is squeezed and slid, the seeds inside the feed hole 3075 will be intercepted and slid to the top of the delivery tube 3076. After the feed hole 3075 is connected with the delivery tube 3076, the seeds inside will fall along the passage, that is, in the process of delivering the seeds, they will be automatically delivered to the dug pit, and finally a certain amount of vegetable seeds will be automatically intercepted and delivered.

The sliding tooth plate 3080 is fixed to the side of the sliding frame 3079. The number of the rotating wheel 3083 and the sliding tooth plate 3080 is set to two groups, and the two groups of rotating wheels 3083 and sliding tooth plates 3080 are symmetrically distributed about the center line of the machine body 1. When the sliding frame 3079 moves downward, it will drive the sliding tooth plate 3080 on the side to move, and then drive the rotating wheel 3083 to rotate counterclockwise through the meshing of teeth, and then use the eccentric connecting rod setting to provide the swing frame 3082 with an oblique downward thrust, so that the bulldozer 3081 pushes the soil to cover the pit, and then the seeds are automatically buried. When the sliding tooth plate 3080 moves upward, it will drive the rotating wheel 3083 to rotate clockwise, and then drive the swing frame 3082 to lift obliquely upward.

[0026] The film cover assembly 5 includes a fixing frame 503, which is fixed on the machine body 1. The fixing frame 503 is provided with a central axis 501. The two sides of the central axis 501 are rotatably connected with driven wheels 504. The fixing frame 503 is clamped with a film roll 502. When the machine body 1 moves, it will drive the rotation of the driven wheels 504, and the rotation of the driven wheels 504 will drive the film roll 502 to rotate to achieve the unwinding of the film. At this time, the film will directly cover the upper surface of the soil. The engine on the machine body 1 is connected to a power shaft 1 506 through a transmission device 2. The surface of the power shaft 1 506 is connected to a power shaft 2 507 through a conveyor belt transmission. The two ends of the power shaft 2 507 and the power shaft 1 506 are rotatably connected with a push frame 505. The push frame 505 is fixed to the side of the machine body 1, and the right end of the push frame 505 extends to the top of the film roll 502. When the equipment moves, another set of transmission devices 2 is used to drive the rotation of the power shaft 506, and then drive the conveyor belt to transport. At this time, when the pushing frame 505 moves with the body 1, it will shovel a certain amount of soil into the conveyor belt. As the conveyor belt is transported, the soil will be driven to the right side of the pushing frame 505. By rolling on the inclined surface, the soil blocks will slide and fall above the film, realizing burial and compaction to avoid being blown away by the wind.

[0027] The working principle is that first, the device, that is, the machine body 1, needs to be driven to the land position where sowing is required, and then the device moves forward along the land. During the forward movement, the engine power in the machine body 1 will transmit the power to the crank shaft 302 through the transmission device 2, and the transmission device 2 here is a transmission structure between the pulleys. When the power is transmitted to the crank shaft 302, it will drive the pressure wheel 303 to rotate with the center of the crank shaft. After that, each time the crank shaft 302 rotates one circle, it will form abutment with the upper surface of the pressure frame 304, and then drive the pressure frame 304 to slide downward, so at this time the pressure frame 304 is It will squeeze the return spring 305 and drive the hollow shaft 3061 to move downward. Then the hollow shaft 3061 will be inserted into the soil to form a seed pit, realizing automatic digging. A sliding pin 3064 is provided. When sliding under the hollow shaft 3061, the sliding pin 3064 will be driven to slide in the spiral groove 3063 of the spiral shape, thereby controlling the rotation of the hollow shaft 3061, and then drilling holes in the soil through the spiral sheet 3062 of the spiral structure. The rotating characteristics can be used to break up some harder soil clods and drill holes at the same time, which is convenient for later seed placement. In addition, a supply device is provided inside the equipment. When the pressing frame 304 moves down, it will penetrate into the liquid fertilizer in the box body 301, and then the fertilizer will enter the inside of the pressing frame 304 through the water inlet grooves 3065 on both sides. As the fertilizer enters, it will enter along the internal drainage groove 3067 of the hollow rotating shaft 3061. When the hollow rotating shaft 3061 moves down, the fixed rod 3066 will slide inside it and disengage from the hole groove at the bottom of the hollow rotating shaft 3061, so that the waste material flows out from the bottom hole of the hollow rotating shaft 3061, and then penetrates into the dug pit, so that fertilization can be carried out while digging the pit. When the reset spring 305 contracts elastically and drives the hollow rotating shaft 3061 to reset, the fixed rod 3066 will block the bottom outflow hole of the hollow rotating shaft 3061 again. Therefore, fertilization is only carried out when digging a pit, thereby saving the input of fertilizer. At the same time, when the pressing frame 304 is pressed and slid downward, the sliding frame 3079 will also be driven to move downward synchronously, and the sliding extrusion of the inclined surface will drive the sliding plate 3074 to slide inside the square tube 3073. In the initial stage, the discharge hole 3075 is in a connected state with the guide tube 3072, and the vegetable seeds inside the seed box 4 will slide into the inside of the cylindrical box 3071, and then flow to the discharge hole 3075 position of the sliding plate 3074 through the pipeline. As the sliding plate 3074 is squeezed and slid, the seeds inside the discharge hole 3075 will be intercepted and slid to the top of the delivery tube 3076. After that, after the discharge hole 3075 is connected with the delivery tube 3076, the seeds inside will fall along the passage, that is, in the process of delivering the seeds, they will be automatically delivered into the dug pit, and finally the automatic interception of a certain amount of vegetable seeds will be realized for delivery.A soil burying device is also provided. When the sliding frame 3079 moves downward, it drives the sliding tooth plate 3080 on the side to move, and then drives the rotating wheel 3083 to rotate counterclockwise through the tooth meshing mode. Then, the eccentric connecting rod is used to provide the swing frame 3082 with a downward thrust, so that the bulldozer plate 3081 pushes the soil to cover the pit, and the seeds after being dropped are automatically buried. The whole realizes an integrated operation. The film covering assembly 5 is provided for covering the land after sowing. When the equipment is moving, it will drive the rotation of the driven wheel 504, and the rotation of the driven wheel 504 will drive the film roll 502 to rotate to realize the unwinding of the film. At this time, the film will directly cover the upper surface of the soil, and when the equipment moves, another set of transmission devices 2 is used to drive the rotation of the power shaft 506, thereby driving the conveyor belt to be transported. At this time, when the push rack 505 moves with the body 1, it will shovel a certain amount of soil into the conveyor belt. With the conveyor belt, the soil will be driven to the right side of the push rack 505. With the rolling of the inclined surface, the soil will slide and fall to the top of the film, realizing burial and compaction to avoid being blown away by the wind. Therefore, the entire equipment realizes the soil burial and fixed integrated operation of digging pits-fertilizing-quantitative placement of vegetable seeds-soil burial-film covering-film, which improves the consistency of the sowing process and the overall efficiency of vegetable sowing.
