Description

Technical Field

[0001] The utility model belongs to the technical field of potato planters, and in particular relates to a disc fertilizing and furrowing system for potato planters. Background Art

[0002] At present, the land preparation effect before sowing by domestic potato growers is poor, and the soil is not loose enough after land preparation, so that during the operation of the potato planter, the fertilizer ditching disc moves up a lot, resulting in the fertilizer receiving bowl not receiving all the fertilizer, resulting in fertilizer waste. In addition, the fertilizer placement point also moves up, affecting the fertilization depth, which is less than 6 cm. Utility Model Content

[0003] In order to solve the problems of fertilizer waste and failure of fertilization depth to achieve an ideal effect, the utility model provides a disc fertilization and furrowing system for a potato planter.

[0004] The technical solution adopted by the utility model is:

[0005] A potato planter disc fertilization and furrowing system comprises a disc furrowing assembly; the disc furrowing assembly comprises a rotating shaft A, a tension spring, a frame, a connecting plate, a fertilizer receiving bowl, a fertilizer guide plate and a fertilizer furrowing disc; the front end of the frame is rotatably connected to the frame of the potato planter through the rotating shaft A, a tension spring is connected between the frame and the frame of the potato planter, the fertilizer furrowing disc is mounted on the rear end of the frame, one end of the connecting plate is mounted on the frame at an adjustable angle through bolts and oblong holes, the fertilizer receiving bowl is mounted on the fertilizer guide plate, the fertilizer guide plate is mounted on the other end of the connecting plate, and the fertilizer receiving bowl and the fertilizer guide plate are arranged to rotate clockwise and tilt through the connecting plate.

[0006] Compared with the prior art, the utility model has the following beneficial effects:

[0007] The utility model rotates the fertilizer receiving bowl and the fertilizer guide plate clockwise by a certain angle in advance to offset the counterclockwise rotation of the disc furrowing assembly when the seeder is operating, thereby accurately applying fertilizer to both sides of the seed potato, thereby improving the utilization rate of the fertilizer. After the improvement, the fertilization depth can reach 16 centimeters. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] In order to better understand the purpose, structure and function of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings.

[0013] like Figure 1 , Figure 3 As shown, the utility model provides a disc fertilizing and furrowing system for a potato planter, comprising a disc furrowing assembly; the disc furrowing assembly comprises a rotating shaft A1, a tension spring 2, a frame 3, a connecting plate 4, a fertilizer receiving bowl 5, a fertilizer guide plate 6 and a fertilizer furrowing disc 7; the front end of the frame 3 is rotatably connected to the frame of the potato planter through the rotating shaft A1, and a tension spring 2 is connected between the frame 3 and the frame of the potato planter, the fertilizer furrowing disc 7 is mounted on the rear end of the frame 3, one end of the connecting plate 4 can be mounted on the frame 3 at an adjustable angle through a bolt 10 and an oblong hole 8, the fertilizer receiving bowl 5 is mounted on the fertilizer guide plate 6, and the fertilizer guide plate 6 is mounted on the other end of the connecting plate 4, and the fertilizer receiving bowl 5 and the fertilizer guide plate 6 are arranged to rotate clockwise and tilt through the connecting plate 4.

[0014] like Figure 2 , Figure 3 As shown, the fertilizer ditching disc 7 is installed on the frame 3 through the rotating shaft B9, and the tail part of one end of the connecting plate 4 is an arc end face, which is matched and arranged on the outside of the rotating shaft B9 so that the connecting plate 4 can rotate around the rotating shaft B9. Two arc-shaped oblong holes 8 concentric with the arc end face are opened on the connecting plate 4, and the connecting plate 4 is fixed to the frame 3 by bolts 10 and the arc-shaped oblong holes 8.

[0015] like Figure 2 As shown, the angle between the axis of the fertilizer receiving bowl 5 and the vertical line is α, and the range of α is 0° to 20°, preferably 12°. The fertilizer receiving bowl 5 and the fertilizer guide plate 6 rotate outward clockwise.

[0016] like Figure 1 As shown, a gap is provided between the fertilization guide plate 6 and the fertilization ditching disc 7, and the front end of the fertilization guide plate 6 is bent toward the fertilization ditching disc 7. The end of the fertilization guide plate 6 is a fertilizer placement point.

[0017] like Figure 1 As shown, there are two disc furrowing assemblies, which are symmetrically installed on the frame of the potato planter, and the fertilizer receiving bowl 5 is arranged on the inner side of the fertilizer furrowing disc 7.

[0018] Working process: When the potato planter is in operation, the two disc ditching components overcome the tension spring 2 and rotate counterclockwise around the rotation axis A1 at a certain angle. The angle is determined by the hardness of the soil, and the general angle is 16° to 20°. After the two disc ditching components rotate, the fertilizer receiving bowl 5 will be offset and will not align with the fertilizer box conduit for potato planting. The fertilizer receiving bowl 5 cannot receive all the fertilizer, and the fertilizer placement point moves up, affecting the fertilization depth.

[0019] At this time, it is necessary to pre-set a certain angle for the fertilizer guide plates 6 in the two disc ditching assemblies, loosen the bolts 10, and rotate about 12° around the rotation axis B9. Figure 2 , to offset the resistance of the soil to the fertilizer ditching disc 7, and then accurately apply the fertilizer to both sides of the seed potato, thereby improving the utilization rate of the fertilizer.
