The width direction of both the conveyor belt 51 and the pinch belt 52 is the longitudinal direction. In a specific layout, in a plan view, the front end of the furrow opener 4 is ahead of the front end of the conveyor belt 51, and the rear end of the furrow opener 4 is ahead of the rear end of the conveyor belt 51 (the rear end of the actual furrow opener 4 is located at a central position in the front-rear direction of the conveyor belt 51); the axes of the two helical members 61 of the casing assembly 6 face the rear end of the conveyor belt 51 with a space between the rear end of the furrow opener 4 and the helical members 61. Adopt this overall arrangement, sweet potato seedling puts in earthing suppression device when whole operation, sweet potato seedling puts in subassembly 5 and earthing subassembly 6 and is in running state always, there is a time interval before the preceding sweet potato seedling is put in the back of getting off and is put in the back sweet potato seedling, in this time interval, after furrow opener 4 opened the slot, earthing subassembly 6 immediately carries earth to fill some with the rear side of slot, make sweet potato seedling put in the head of getting off back sweet potato seedling and is heightened and expose soil by the bed hedgehopping, so can realize that partly lying of sweet potato seedling and its head is vertical state, be favorable to the subsequent growth of sweet potato seedling.
In the preferred embodiment, in order to realize the adjustment of the thickness of the casing soil for sweet potato seedlings, as shown in fig. 2 and fig. 10, each screw part 61 is connected to the frame 1 through an adjusting mechanism 63. The adjusting mechanism 63 comprises a transmission case 631, a transmission assembly 632 and a first adjusting rod 633; the power shaft 62 is rotatably arranged on the frame 1 and is connected with a power source; the transmission case 631 is rotatably mounted on the power shaft 62; one end of the first adjusting rod 633 is rotatably connected with the transmission case 631, the other end of the first adjusting rod 633 is connected with the frame 1, and the connection position between the first adjusting rod and the frame 1 is adjustable, specifically, the first adjusting rod 633 is provided with a screw portion, the frame 1 is provided with a first extending portion 11 with a through hole, the first adjusting rod 633 passes through the through hole of the first extending portion 11, and two first nuts 634 are screwed thereon, the two first nuts 634 respectively abut against two sides of the first extending portion 11, when the angle of the transmission case 631 needs to be adjusted, only the axial positions of the two first nuts 634 on the first adjusting rod 633 need to be adjusted; the screw part 61 is rotatably arranged on the transmission case 631, and the rotating center of the screw part is not coaxial with the rotating center of the power shaft 62; the transmission assembly 632 is used for establishing a transmission relationship between the screw member 61 and the power shaft 62, and in this embodiment, the transmission assembly 632 is a chain transmission assembly. Through the structure, the pitching angle of the transmission case 631 is used as an adjusting object, so that the deep rapid adjustment of the soil penetration of each spiral part 61 can be realized, the soil conveying capacity of the spiral parts 61 is controllable, and the purpose of reasonably covering the sweet potato seedlings with soil is achieved.
As shown in the attached figure 2, the pressing component 7 is used for pressing the floating soil covered around the sweet potato seedlings by the soil covering component 6, so that the floating soil is pressed tightly, and the loss of the floating soil under the external effects of rain wash and the like is prevented to cause the exposure of the sweet potato seedlings. Specifically, the press assembly 7 includes a connecting frame 71, a wheel frame 72, a press wheel 73 and a second adjusting rod 74; the connecting frame 71 is mounted on the machine frame 1, the press wheel 73 is rotatably mounted on the wheel frame 72, the machine frame 1 is rotatably mounted on the connecting frame 71, one end of the second adjusting rod 74 is hinged on the connecting frame 71, the other end of the second adjusting rod is connected with the connecting frame 71, and the connecting position of the second adjusting rod and the connecting frame 71 is adjustable. Specifically, the connecting frame 71 has a second extending portion 711, a through hole is formed in the second extending portion 711, the second adjusting rod 74 passes through the through hole in the second extending portion 711, the second adjusting rod 74 is screwed with two second nuts 75, the two second nuts 75 respectively abut against two sides of the second extending portion 711, and when the pitch angle of the wheel frame 72 needs to be adjusted, only the axial positions of the two second nuts 75 on the second adjusting rod 74 need to be adjusted.
Since the height of the press wheel 73 is adjusted by adjusting the pitch angle of the wheel frame 72, the adjustable range of the height of the press wheel 73 is small, and the connecting frame 71 can be adjusted in position in the vertical direction with respect to the frame 1 in order to provide a wider adjustable range for the press wheel 73. Thus, when the height of the press wheel 73 is adjusted, the height of the connecting frame 71 can be roughly adjusted, and then the pitching angle of the wheel frame 72 is adjusted to realize the accurate adjustment of the height of the press wheel 73.
Two press wheels 73 are symmetrically arranged on each wheel frame 72 from left to right, and the rotating shafts of the press wheels 73 are obliquely arranged, so that the two press wheels 73 are arranged in a V shape when viewed from the front and the back (as shown in figure 3). Through this structure, press wheel 73 not only can carry out the suppression to earth, still can extrude two ditches in the both sides of sweet potato seedling, is favorable to follow-up fertilization watering. The spacing between the two press wheels 73 is adjustable to suit specific press requirements.
Because the furrow opener 4, the soil covering assembly 6 and the press assembly 7 all work on the ridge formed by the ridge forming mechanism 3, the rear side of the frame 1 lacks strong support, and therefore, the supporting wheel 10 is installed at the rear side of the frame, and the height position of the supporting wheel 10 relative to the frame 1 is adjustable so as to prevent the supporting wheel 10 from making the furrow opener 4, the soil covering assembly 6 or the press assembly 7 overhead.
