Detailed Implementation

[0018] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention. The embodiments of the present invention will be further described in detail below with reference to the accompanying drawings:

[0019] like Figures 1-5 As shown, the straw bundling and burying mechanism for the yam planting machine of this utility model includes a structural frame constructed from aluminum alloy profiles 10 and fastening bolts. Two sets of symmetrical straw bins 14 are fixed to the structural frame by bolts. The space formed between each set of straw bins 14 is used to store bundled straw. A driven shaft 12 is also rotatably mounted on the structural frame via bearings. U-shaped notch discs 13 are fixedly spaced between the driven shafts 12. The U-shaped notches on the U-shaped notches 13 are used to feed individual straw bundles when they are facing upwards. Inside, a straw clamping frame 20 is provided below the structural frame to receive individual straw bales that fall as the U-shaped notch disc 13 rotates. A hinged multi-bar mechanism 21 is provided on the structural frame. The hinged multi-bar mechanism 21 is driven by a motor and has two hinge points with the straw clamping frame 20. Driven by the motor, the hinged multi-bar mechanism 21 lifts the straw clamping frame 20, rotates it ninety degrees, and moves it laterally so that the entire straw clamping frame 20 is located outside the structural frame, thereby dropping the straw bales.

[0020] Preferably, a four-bar linkage 11 is also hinged to the structural frame. The bottom bar of the four-bar linkage 11 is connected to the main drive shaft 23 rotatably mounted on the aluminum alloy profile 10. The main drive shaft 23 rotates under the drive of a motor, causing the four-bar linkage 11 to swing cyclically. The two ends of the four-bar linkage 11 are respectively fixed to the left and right driven shafts 12. Thus, under the drive of the four-bar linkage 11, the straw bales are alternately removed from the storage cavity between the straw bin plates 14 and poured into the straw clamping frame 20 by the left and right U-shaped notch discs 13.

[0021] Preferably, the straw clamping frame 20 comprises a series of U-shaped falling frames 18 fixed in series by a series of rods 19, a second driving motor 16 fixed on the U-shaped falling frame 18 and a crank clamp 17 driven by the second driving motor 16, the crank clamp 17 is turned by 180 degrees and covers the upper opening of the U-shaped falling frame 18, so as to clamp and fix the straw bundle in the U-shaped falling frame 18, and ensure that the straw bundle does not displace with the U-shaped falling frame 18 before displacement to the throwing position. When the articulated multi-link mechanism 21 is unfolded to the throwing state ( Figure 5 ), the second driving motor 16 drives the crank clamp 17 to reset, so that the straw bundle falls into the planting hole with a pre-punched hole.

[0022] Preferably, the articulated multi-link mechanism 21 for driving the straw clamping frame 20 and the first driving motor 22 for driving the articulated multi-link mechanism 21 are further arranged on the structural frame, and the first driving motor 22 is fixed on the aluminum alloy profile 10. When the articulated multi-link mechanism 21 is unfolded to the throwing state ( Figure 5 ), the second driving motor 16 drives the crank clamp 17 to reset, so that the straw bundle falls into the planting hole with a pre-punched hole.

[0023] Preferably, the left and right symmetrical two inclined guide plates 15 are further arranged on the structural frame by bolt fixing, for guiding the straw bundle taken out by the U-shaped notch disc 13 to fall into the U-shaped falling frame 18.

[0024] It should be emphasized that the embodiments of the utility model are illustrative rather than limiting, and therefore the utility model is not limited to the embodiments described in the specific embodiments, and any other embodiments derived by those skilled in the art according to the technical scheme of the utility model also belong to the protection scope of the utility model.
