A disk channel 29 is opened on the rotating disk 28. The seed grabbing bar 30 is detachably connected to the rotating disk 28, and is provided with a seed grabbing cavity 31 and a seed transfer channel 32 which are interconnected. The seed transfer channel 32 is connected to the disk channel 29. The seed grabbing bar 30 is detachable so that when different plant seeds are grabbed, the seed grabbing bar 30 with a seed grabbing cavity 31 of different volumes can be replaced. The seed storage box 33 is fixedly connected to the rear wall of the component cavity 3, and the plant seeds are placed in the seed storage box 33. A collecting channel 35 is provided on the collector 34, and the collector 34 is fixedly connected to the upper end of the first seed transfer tube 36, and the lower end of the first seed transfer tube 36 is fixedly connected to the bottom wall of the component cavity 3.

The second seed transfer tube 37 extends to the bottom of the machine body 1, and the seed outlet of the second seed transfer tube 37 faces one of the digging shovels 8, so that the plant seeds can fall into the pits dug by the two digging shovels 8.

[0043] According to an optional embodiment of the present invention, a vibration conduction block 38 is fixedly connected to the first seed transfer tube 36, and a rotating plate 39 is rotatably connected to the vibration conduction block 38 via a self-resetting rotating shaft 40. The rotating plate 39 extends between two transmission teeth of the driven gear 24. The collision of the rotating plate 39 with the vibration conduction block 38 can cause the vibration conduction block 38 to vibrate, thereby transmitting the vibration to the first seed transfer tube 36 and the second seed transfer tube 37 to prevent clogging by plant seeds.

[0044] According to an optional embodiment of the present invention, one end of the linkage rod 22 is rotatably connected to a push wheel 41, and the push wheel 41 can reduce the friction between the linkage rod 22 and other components during transmission, making the linkage smoother, and applying lubricating oil to the push wheel 41 can further reduce the friction.

[0046] According to an optional embodiment of the present invention, the rotating disk 28 and the seed grabbing bar 30 are both located above the seed storage box 33 , so that the seed grabbing bar 30 can grab the plant seeds in the seed storage box 33 .

[0047] According to an optional embodiment of the present invention, the collector 34 is located at the lower right side of the rotating disk 28 , and the side of the collector 34 facing the rotating disk 28 is curved, so that plant seeds can smoothly fall from the disk channel 29 into the collecting channel 35 .

[0048] According to an optional embodiment of the present invention, it also includes: Step 4, adding fertilizers and nutrient solutions to the soil where the plant seeds are sown. Fertilizers commonly used in mixed coniferous and broad-leaved forests include organic fertilizers, compound fertilizers, trace element fertilizers, etc. Organic fertilizers can increase the organic matter content in the soil, improve soil structure, and enhance the soil's ability to retain water and fertilizer, which is beneficial to tree growth. Compound fertilizers can supplement the main nutrients such as nitrogen, phosphorus, and potassium that are lacking in the soil. Trace element fertilizers are targeted at soils that are specifically deficient in trace elements, such as soils that are deficient in zinc, iron, and manganese. The nutrient solution can be selected from a nutrient solution containing trace elements or a nutrient solution containing microorganisms.

[0049] According to an optional embodiment of the present invention, in the step one, the boundary of the planting area is marked by a rope, and the rope is selected to be a conspicuous color that is obviously different from the soil, such as red. In the step two, after testing the soil in the planting area, it is also necessary to determine the type of fertilizer and nutrient solution that needs to be added.

[0050] Working principle of the soil digging and sowing machine: the machine body 1 is moved to the area where sowing is required by the wheels 2, and the motor 20 is turned on. The motor 20 drives the toothless gear 21 and the second permanent magnet 23 to rotate counterclockwise. First, the second permanent magnet 23 pushes the right wall of the second wedge plate 14, so that the second wedge plate 14 moves to the left. The second wedge plate 14 pushes the first wedge plate 13 and the displacement plate 10 to overcome the elastic force of the elastic member 17 and move downward. Since the transmission column 9 extends between the first transmission bar 11 and the second transmission bar 12, the first transmission bar 11 pushes the two transmission columns 9 and the digging shovel 8 to move downward, and the two digging shovels 8 The digging shovel 8 is inserted into the soil while moving downward along the two inclined guide channels 7 until the two digging shovels 8 abut against each other. At this time, the bottom wall of the second wedge plate 14 abuts against the first wedge plate 13, and the first wedge plate 13 no longer moves downward. The second permanent magnet 23 disengages from the second wedge plate 14, and the toothless gear 21 continues to rotate counterclockwise. The toothless gear 21 meshes with the driven gear 24, driving the driven gear 24, the first linkage wheel 25, the linkage chain 26, the second linkage wheel 27, the rotating disk 28, and the seed grabbing bar 30 to rotate clockwise, and the seed grabbing cavity 31 enters the plant seeds in the seed storage box 33 clockwise. , wherein a rated number of plant seeds enter the seed grasping cavity 31, the second permanent magnet 23 and the third wedge plate 19 are counteracted, the second permanent magnet 23 pushes the third wedge plate 19 and the component total plate 5 to move upward, so that the two digging shovels 8 drive the excavated soil to move upward, and a pit is formed on the ground. When the seed grasping bar 30 rotates more than 180 degrees, the plant seeds in the seed grasping cavity 31 will fall into the collecting channel 35 along the seed transfer channel 32 and the disk channel 29 under the action of gravity, and fall into the pit on the ground through the guidance of the first seed transfer tube 36 and the second seed transfer tube 37. When the first permanent magnet 15 moves to the second permanent magnet 15, the plant seeds in the seed grasping cavity 31 will fall into the pit on the ground along the seed transfer channel 32 and the disk channel 29. When the first wedge plate 13 is on the left side of the iron 23, the magnetic attraction of the second permanent magnet 23 attracts the first permanent magnet 15 and the second wedge plate 14, so that the second wedge plate 14 is separated from the first wedge plate 13. After the first wedge plate 13 loses the supporting force of the second wedge plate 14, the first wedge plate 13 and the displacement plate 10 move up and reset under the elastic force of the elastic member 17, and the second transmission bar 12 drives the two digging shovels 8 to move up and away from each other along the two guide channels 7. The soil on the two digging shovels 8 will fall back into the pit and automatically backfill the pit, quickly completing the operations of digging, sowing and backfilling.

[0051] When the driven gear 24 rotates, one of the transmission teeth of the driven gear 24 will push the rotating piece 39 to overcome the rebound force of the self-resetting shaft 40 and rotate clockwise. When the transmission tooth disengages from the rotating piece 39, the rotating piece 39 will rebound quickly under the action of the rebound force of the self-resetting shaft 40 to collide with the vibration conduction block 38, and the vibration conduction block 38 will vibrate. The vibration is transmitted to the first seed transfer tube 36 and the second seed transfer tube 37 to prevent plant seeds from being blocked in the first seed transfer tube 36 or the second seed transfer tube 37 and causing the phenomenon of being unable to be sown. Each transmission tooth on the driven gear 24 will push the rotating piece 39 one by one, so that the vibration conduction block 38 will continue to vibrate.

[0052] The machine body 1 subsequently moves to the next position, and the linkage rod 22 continues to rotate counterclockwise, repeating the above principle to perform sowing operations at other positions, which will not be described again here.

[0053] The present invention can realize quick digging of soil holes through a device, i.e., a soil digging and sowing all-in-one machine, and then automatically grab a rated number of plant seeds in a seed storage box 33 through a seed grabbing cavity 31 on a seed grabbing bar 30, and allow the plant seeds to automatically enter the hole after being guided by a series of components to complete automatic sowing, and finally the dug soil can be automatically backfilled into the hole without manual backfilling, and three cumbersome planting steps can be completed in one step, thereby improving the work efficiency of vegetation restoration and reducing the waste of manpower and material resources. The above operations can be realized by driving only one motor 20, the components are highly linked, and the device is highly practical.

[0054] The components, modules, mechanisms and devices not described in detail in the present invention are all universal standard parts or components known to those skilled in the art, and their structures and principles can be known to those skilled in the art through technical manuals or conventional experimental methods.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention, rather than to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present invention.
