A tension spring is connected between the second frame plate and the movable frame part one. When the connecting plate moves to one end away from the first frame plate, the front end of the guide rail moves downward under the action of weight to facilitate the concentric clamp to be closer to the planting hole and facilitate placement.

The main drive shaft rotates under the drive of the motor to make the hinged four-bar mechanism swing cyclically, and the two ends of the hinged four-bar mechanism are respectively fixed to the left and right driven shafts, so that the left and right U-shaped notched plates are driven by the hinged four-bar mechanism to alternately take out the straw bales from the storage cavity between the straw bin boards and pour them into the straw clamping frame.

[0010] Preferably, the straw clamping frame includes a series rod that fixes a plurality of U-shaped falling frames in series, and also includes a second drive motor fixed to the U-shaped falling frame and a crank clamp driven by the second drive motor. The crank clamp is turned 180 degrees and covers the upper opening of the U-shaped falling frame to clamp and fix the straw bale in the U-shaped falling frame, ensuring that the straw bale does not move with the U-shaped falling frame before it moves to the delivery position. When the hinged multi-rod mechanism is unfolded to the delivery state (Figure), the second drive motor drives the crank clamp to reset, so that the straw bale falls into the planting pit with holes drilled in advance.

[0011] Preferably, a hinge multi-rod mechanism for driving the straw clamping frame and a first drive motor for driving the hinge multi-rod mechanism are also provided on the structural frame, and the first drive motor is fixed on the aluminum alloy profile.

[0012] In a preferred embodiment, a discharge barrel is fixed to the chassis frame by bolts, a multi-link mechanism driven by a multi-link drive motor is hingedly provided on the base, and a bulldozer arm is fixed at the front end of the multi-link mechanism. The base, the multi-link mechanism, the multi-link drive motor and the bulldozer arm are arranged in two groups obliquely symmetrically at the bottom of the chassis frame. After the guide rail clamping planter completes the placement of the yam, the soil near the yam is pushed by the bulldozer to cover the yam.

[0013] The advantages and positive effects of the present invention are: The structure is compact and reasonable, and the originally purely manual planting work is automated. First, the supporting moving mechanism 22 is moved to the planting position, and then the planting punching mechanism 21 is used to punch holes. Then the yam planting machine uses the straw bundling and landfilling mechanism 23 to insert the straw into the soil hole. Then the yam segment discharging mechanism 25 discharges a piece of planted yam segment, which is clamped by the guide rail clamping planter 16 and then moved to the soil hole position and put down. Finally, the bulldozer arm 35 covers the loose soil near the soil hole on the yam planting block. It has a high degree of automation and can be operated by a single person.

[0014] It has high efficiency and high standardization. Compared with manual planting, the efficiency is greatly improved, and the planting indicators are more unified and the planting pits are more regular, which is conducive to improving the survival rate and development of yam.

[0015] The steel wire is first spread out in the contoured ring groove under the push of the clamping wheel, and then the straw is put in. The steel wire is tightened under the action of the clamping wheel to tie up the lower end of the straw bale, and then the wire feeding tube is sleeved on the slide and inserted into the soil hole. Then the steel wire is loosened under the push of the clamping wheel and moves downward for a distance under the action of the slide to break away from the straw. Then the steel wire is tightened and the slide and the wire feeding tube sleeve are pulled out. The structure is simple and can quickly fix the lower end of the upright straw bale and insert it into the soil pit, and then withdraw it. The straw can be quickly, accurately and completely inserted into the pit, which is more convenient and quicker than manual operation.

[0016] The stored straw bales can be pre-installed one by one according to the punched positions of yam planting and then inserted upright into the landfill. Compared with the existing technology through manual operation, it is more convenient and quick, the equipment has a high degree of automation, and the movement is continuous and the equipment is compact.

[0017] The concentric clamp is used to clamp the yam planting block, which can be easily transferred to the planting position with holes drilled in advance. The concentric clamp holding the yam planting block is moved into place under the translational action of the guide rail and the linear slider for planting. Compared with traditional manual planting, it is more labor-saving and convenient, without the need for repeated bending and kneeling, freeing people from tiring and repetitive production activities.

The punching position of the punching screw 20 coincides with the position of the guide rail clamping planter 16 for placing the yam. In this way, the device can complete the planting process after moving to a working position without the need for multiple moves.

[0028] In a preferred embodiment, a discharge barrel 39 is fixed to the chassis frame 10 by bolts, a multi-link mechanism 36 driven by a multi-link drive motor 37 is hingedly provided on the base 38, and a bulldozer arm 35 is fixed at the front end of the multi-link mechanism 36. The base 38, the multi-link mechanism 36, the multi-link drive motor 37 and the bulldozer arm 35 are arranged in two groups obliquely symmetrically at the bottom of the chassis frame 10. After the guide rail clamping planter 16 completes the placement of the yam, the soil near the yam is pushed by the bulldozer arm 35 to cover the yam.

[0029] During the specific implementation, the supporting moving mechanism 22 is first moved to the planting position, and then the planting punching mechanism 21 is used to punch holes. Then the yam planting machine uses the straw bundling and filling mechanism 23 to insert the straw into the soil hole. Then the yam segment discharging mechanism 25 discharges a piece of planting yam segment, which is clamped by the guide rail clamping planter 16 and then moved to the soil hole position and put down. Finally, the bulldozer arm 35 covers the loose soil near the soil hole on the yam planting block.

[0030] It should be emphasized that the embodiments described in the present invention are illustrative rather than restrictive, and therefore the present invention is not limited to the embodiments described in the specific implementation manners. Any other implementation manners derived by those skilled in the art based on the technical solutions of the present invention also fall within the scope of protection of the present invention.
