DETAILED DESCRIPTION

[0024] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0025] like Figures 1 to 7 As shown, the embodiment of the utility model provides a multi-hole sowing device for digging holes in a field and sowing seeds in the holes, thereby improving the automation degree and sowing efficiency of the sowing operation.

[0026] Please refer to Figure 1 , Figure 2 and Figure 3The multi-hole sowing device includes: a seed box 2 for containing seeds to be sown is provided on the frame 1, a movable frame 3 that can be raised and lowered and a driving assembly 4 that is transmission-connected to the movable frame 3 are also provided on the frame 1, a vertical drill rod 31 is provided on the movable frame 3, when the movable frame 3 is driven down by the driving assembly 4, one end of the drill rod 31 is inserted into the field and a hole is dug on the field, a driving rod 32 that is perpendicular to the drill rod 31 is provided on the drill rod 31, a seed guide tube 21 for guiding the movement of seeds is provided on the seed box 2, and the seed guide tube 21 extends from one end of the seed box 2 to the drill rod 31 Directly below, a movable switch tongue 22 is provided on the seed conduit 21. When the switch tongue 22 extends into the seed conduit 21, the seed conduit 21 is blocked and the seeds are prevented from falling along the seed conduit 21 to below the drill rod 31. A rotatable movable plate 5 is also provided on the frame 1, and the movable plate 5 has a slot 51 for the driving rod 32 to pass through. A return spring 52 is provided on the movable plate 5. The return spring 52 extends into the slot 51 and the included angle between the length direction of the return spring 52 and the horizontal direction is an acute angle. When the driving rod 32 descends with the drill rod 31 and abuts against the return spring 52 When the driving rod 32 is lifted up, the driving rod 32 pushes the movable plate 5 to rotate until the driving rod 32 is separated from the return spring piece 52 and enters the slot 51. When the driving rod 32 rises with the drill rod 31 and abuts against the return spring piece 52, the return spring piece 52 is deformed to avoid the driving rod 32 so that the driving rod 32 can withdraw from the slot 51. The movable plate 5 is also provided with a movable shaft 6 and a tension spring 7. One end of the relative ends of the movable shaft 6 is rotatably connected to the movable plate 5, and the other end is rotatably connected to the switch tongue 22. One end of the relative ends of the tension spring 7 is fixedly connected to the movable plate 5, and the other end is fixedly connected to the switch tongue 22. The end is fixedly connected to the seed conduit 21, and when the movable plate 5 rotates under the drive of the driving rod 32, the movable shaft 6 pulls the switch tongue 22 to make the switch tongue 22 withdraw from the seed conduit 21, so that the seeds blocked by the switch tongue 22 can continue to fall along the seed conduit 21, and the tension spring 7 is stretched. After the driving rod 32 is separated from the return spring 52, the tension spring 7 returns to its original state and drives the movable plate 5 to reset. At this time, the switch tongue 22 is reset under the push of the movable shaft 6 and blocks the seed conduit 21, so that the movable plate 5 and the switch tongue 22 are automatically reset.

[0027] like Figures 4 to 7As shown, the operation steps of using the multi-hole sowing device provided by this embodiment to perform sowing operations are as follows: first, the frame 1 is transported to the field and seeds are placed in the seed box 2, the seed box 2 is operated to allow a certain amount of seeds to enter the seed conduit 21 and the seeds entering the seed conduit 21 are blocked by the switch tongue 22, the drive assembly 4 is started to drive the movable frame 3 to descend in the vertical direction, so that one end of the drill rod 31 is inserted into the field and holes are dug on the field, and as the drill rod 31 moves, the drive rod 32 descends and abuts against the return spring 52. Since the return spring 52 is inclined, when the drive rod 32 descends, it pushes the movable plate 5 to rotate so that the switch tongue 22 exits the seed conduit 21 under the pull of the movable shaft 6 and the tension spring 7 is lengthened. At this time, the seeds blocked by the seed conduit 21 continue to fall along the seed conduit 21, and after the drive rod 32 continues to descend and disengages from the return spring 52 and enters the slot 51, The tension spring 7 restores its original length and pulls the movable plate 5 to rotate in the opposite direction so that the switch tongue 22 is reset under the push of the movable shaft 6, and then the driving component 4 drives the movable plate 5 to rise in the vertical direction so that the drill rod 31 withdraws from the hole dug in the field. At this time, the seeds in the seed guide tube 21 fall into the hole under the guidance of the seed guide tube 21 to complete the sowing, and during the rising process of the drill rod 31, the driving rod 32 moves in the slot 51, and the driving rod 32 moves to the position abutting against the return spring piece 52 and pushes the return spring piece 52 to deform. The return spring piece 52 avoids the driving rod 32 so that the driving rod 32 can withdraw from the movable plate 5 and reset, thereby automatically completing the digging of the hole, sowing and resetting actions. After sowing is completed, the frame 1 is moved to the next sowing location and the seed box 2 is operated to add seeds into the seed guide tube 21 again. The driving component 4 drives the movable frame 3 to move back and forth in the vertical direction to continuously carry out the sowing operation. The multi-hole seeding device provided in this embodiment can automatically perform hole digging and seeding, thereby improving the degree of automation of the equipment, helping to reduce the labor intensity of operators and improving seeding efficiency.

The telescopic rod 42 is driven by the cylinder 41 to extend or retract into the cylinder 41, and the movable frame 3 can be driven to move through the action of the telescopic rod 42. When the telescopic rod 42 extends out of the cylinder 41, the movable frame 3 descends in the vertical direction. At this time, one end of the drill rod 31 is inserted into the field and a hole is dug in the field. When the telescopic rod 42 is retracted into the cylinder 41, the movable frame 3 rises in the vertical direction. At this time, the drill rod 31 withdraws from the hole so that the seeds can fall into the hole along the seed guide tube 21 to complete the sowing.

[0029] In detail, the frame 1 is further provided with a guide rod 11, which is vertically arranged on the frame 1 and the movable frame 3 is provided with a guide hole matched with the guide rod 11.
