With the rotation of the walking wheels, the first pulley 61 is synchronously rotated, the second pulley 62 is synchronously rotated with the rotating shaft 2 through the transmission of the belt 63, the rotating block 21 is rotated with the rotating shaft 2, the connecting rod 31 is circularly moved with the rotating block 21, the connecting rod 31 and the rotating block 21 are hingedly connected at the eccentric position, the vertical rod 32 is slidably connected with the supporting rod 33, the supporting rod 33 can limit the vertical rod 32 during the up-and-down movement, ensures the stable operation of the vertical rod 32, when the connecting rod 31 is rotated to the high position with the rotating block 21, the vertical rod 32 is lifted by the connecting rod 31, when the rotating block 21 is rotated to the low position with the rotating block 21, the vertical rod 32 is lowered in the inside of the storage box 1, the dredging blade 34 reciprocally moves during the lifting and lowering of the vertical rod 32, the dredging blade 34 is located in the connecting channel between the bottom of the storage box 1 and the discharge bin 41, and the purpose of dredging is achieved, when the solid fertilizer falls in the channel, the dredging blade 34 moves up and down to push the blocked solid fertilizer, so that the solid fertilizer is unstable and can quickly fall, which is beneficial to the subsequent spreading of the solid fertilizer.

[0036] The auxiliary spreading mechanism 4 comprises a discharging bin 41 fixedly connected to the bottom of the storage tank 1, which is in communication with the inside of the storage tank 1. When the solid fertilizer in the inside of the storage tank 1 enters the inside of the discharging bin 41, the solid fertilizer will fall on the surface of the guide base 42. The bottom of the discharging bin 41 is fixedly connected with the guide base 42. Due to the feature that the guide base 42 is high in the middle and low at the periphery, the falling solid fertilizer will slide uniformly from the central high area of the guide base 42 to the periphery low area, and finally fall on the guide base 42, which has a preliminary dispersion effect. A plurality of discharging holes 43 are uniformly arranged in the inner wall of the side away from the center of the guide base 42, so that the solid fertilizer can continue to fall from the inside of the discharging hole 43. At the same time, the plurality of discharging holes 43 are beneficial to the multi-directional falling of the solid fertilizer, which helps to uniformly spread the solid fertilizer into the furrow. The bottom inner wall of the guide base 42 is provided with a sliding groove 44, and the sliding groove 44 is slidably connected with an opening and closing plate 45. The opening and closing plate 45 is located below the guide base 42, and the profile diameter of the opening and closing plate 45 is consistent with the profile diameter of the guide base 42. The top of the opening and closing plate 45 is fixedly connected with a pull rod 46, and the top end of the pull rod 46 is slidably connected with the bottom of the vertical rod 32. In the initial state, the top end of the opening and closing plate 45 is not pressed by the pull rod 46 and the vertical rod 32, so that the top end of the opening and closing plate 45 is stationary in the sliding groove 44. At this time, the opening and closing plate 45 is located below the guide base 42, and the opening and closing plate 45 is tightly attached to the guide base 42, so that the discharging passage of the discharging hole 43 is blocked by the opening and closing plate 45. By using the downward pressure of the pull rod 46 on the vertical rod 32, the opening and closing plate 45 slides downward in the sliding groove 44, and at the same time, the opening and closing plate 45 is separated from the guide base 42. At this time, the discharging passage of the discharging hole 43 is re-opened, so that the solid fertilizer can normally fall and roll onto the surface of the opening and closing plate 45 and then into the furrow. Not only does this increase the spreading range of the solid fertilizer, but also the solid fertilizer is dispersed again when it falls on the surface of the opening and closing plate 45, so that the solid fertilizer is more uniformly spread. At the same time, the intermittent lifting of the opening and closing plate 45 by the pull rod 46 causes the opening and closing plate 45 to intermittently contact and separate from the guide base 42, so that the discharging hole 43 has a discharging interval, so that only a small amount of solid fertilizer is discharged each time, avoiding excessive use of solid fertilizer. A plurality of discharging grooves 47 are uniformly arranged in the top inner wall of the opening and closing plate 45 and below the guide base 42.

[0037] The overall outer contour of the material guiding base 42 is high in the middle and low at the four corners, the top of the opening and closing plate 45 is close to the area of the discharging chute 47 and is located below the material guiding base 42, which is a concave surface, the outer wall of the bottom end of the opening and closing plate 45 is a slope, the top of the opening and closing plate 45 and the area below the discharging hole 43 is a flat surface, a plurality of partition plates 51 are uniformly and fixedly connected to the top of the material guiding base 42, a plurality of discharging holes 43 are distributed between adjacent two partition plates 51, the flat surface at the top of the opening and closing plate 45 is used to close the falling channel of the discharging hole 43 when the opening and closing plate 45 is combined with the material guiding base 42, and when the opening and closing plate 45 is separated from the material guiding base 42, the solid fertilizer in free fall will fall on the concave surface area and the slope area at the top of the opening and closing plate 45, in the concave surface area, the solid fertilizer in the concave surface can fall off by using the discharging chute 47, achieving the purpose of spreading solid fertilizer in the area below the opening and closing plate 45, and through the cooperation of the slope and the concave surface, the uniformity of the solid fertilizer spreading can be further improved, so that the solid fertilizer is evenly distributed in every place in the furrow, ensuring that after subsequent soil covering, the poplar can be well nourished.

[0038] The auxiliary stirring mechanism 7 comprises a fixed frame 71 fixedly connected to the top end side wall of the storage tank 1, a support rod 72 slidingly connected inside each of the two fixed frames 71, a support seat 73 fixedly connected to the top of the end of the support rod 72 away from the fixed frame 71, a rotating ring 74 rotatably connected to the top of the support seat 73, a plurality of stirring blades 75 fixedly connected to the bottom of the rotating ring 74, a transmission wheel 76 fixedly connected to the outer wall of the rotating shaft 2, the outer wall of the transmission wheel 76 being in frictional engagement with the outer wall of the rotating ring 74, the outer wall of the rotating ring 74 and the outer wall of the transmission wheel 76 being inclined surfaces that can continuously fit, the outer surfaces of the rotating ring 74 and the transmission wheel 76 being rough, a support spring 81 fixedly connected to the inner side wall of the fixed frame 71 below the end of the support rod 72, the top of the support spring 81 being fixedly connected to the bottom of the support rod 72, a knocking block 82 further fixedly connected to the outer wall of the rotating shaft 2 above the support rod 72, the arc-shaped end of the knocking block 82 being in abutting engagement with the top of the support rod 72, the rotating shaft 2 rotating with the transmission wheel 76, under the action of friction, causing the transmission wheel 76 to rotate with the rotating ring 74 on the top of the support seat 73, and the rotating ring 74 rotating synchronously with the stirring blades 75, when a plurality of solid fertilizers are added to the inside of the storage tank 1, the stirring effect can be achieved, so that the plurality of solid fertilizers can be uniformly mixed during movement above the furrow in the storage tank 1, compared with manual stirring, the user's physical strength and time are saved, in addition, when the rotating shaft 2 rotates with the knocking block 82 and contacts the top of the support rod 72, the arc-shaped end of the knocking block 82 will press down the support rod 72, causing the support rod 72 to slide downward in the fixed frame 71, during which the support spring 81 is compressed, when the knocking block 82 separates from the support rod 72, under the resilience of the support spring 81, the support rod 72 is reset, and the rotating ring 74 and the stirring blades 75 vibrate, the above process is repeated, which can increase the vibration frequency of the rotating ring 74 and the stirring blades 75, and the vibration can avoid the solid fertilizer from adhering to the surface of the rotating ring 74 and the stirring blades 75, improve the stirring effect, and has the self-cleaning effect, facilitating multiple uses.
