The feeding box 1 is an existing mechanism, generally a transversely arranged long-strip box body, a plurality of feed openings 1-1 are transversely arranged at the bottom of the feeding box at intervals, and a plurality of ridge platforms for ploughing can be fed during operation, such as seeding and topdressing. Specifically, as shown in fig. 3, a conical slope 1-3 is arranged at the middle position in the feeding box 1 for guiding the seeds or fertilizers stored therein to the middle position, the bottom of the conical slope 1-3 is communicated with a plurality of tray installation cavities 1-4 arranged at intervals, the bottoms of the tray installation cavities 1-4 are communicated with the discharge ports 1-1 one by one, a transmission shaft 9 is coaxially and rotatably installed between the tray installation cavities 1-4, a plurality of discharge trays 9-1 are coaxially and fixedly arranged on the transmission shaft 9, the discharge trays 9-1 are rotatably arranged in the corresponding tray installation cavities 1-4 one by one, a plurality of discharge transfer grooves 9-2 are arranged at equal angles on the circumference of each discharge tray 9-1, when the discharge tray 9-1 rotates, the seeds or the fertilizers are intermittently transferred to the discharge ports 1-1 through the discharge transfer grooves 9-2 and discharged, one end of the transmission shaft 9 extends out of the feeding box 1 and coaxially fixes a transmission wheel 9-3 which is used for being connected with an external transmission system so as to drive the plurality of blanking discs 9-1 to rotate.

Because the ridge of ploughing is not necessarily completely straight, the accuracy of unloading position is hardly guaranteed to solitary feed tank 1 when unloading, so this scheme has add corresponding quantity's unloading position control frame, and it is shown with combination figure 1, figure 3 that, lateral wall an organic whole sets up a plurality of vertical sleeves 1-2 and is used for the grafting installation of unloading position control frame behind feed tank 1, vertical sleeve 1-2 with unloading mouth 1-1 is the one-to-one setting, and an unloading position control frame is installed to every vertical sleeve 1-2 below.

Referring to fig. 2, the blanking position adjusting frame comprises an inverted T-shaped support rod 2, a cross beam 3, an adjusting screw 6, a positioning cylinder 7, two upright rods 4 and two ridge positioning wheels 5. The upper ends of the inverted T-shaped support rods 2 are inserted into the corresponding vertical sleeves 1-2 in a sliding mode, so that the blanking position adjusting frames are in contact with ridge platforms of cultivated land all the time under the action of dead weight in the operation process, it is worth mentioning here that in order to facilitate the lifting of the blanking position adjusting frames away from the ground under the non-operation condition, threaded holes are formed in the lower ends of the side walls of the vertical sleeves 1-2 and are connected with locking bolts in a screwing mode, the inverted T-shaped support rods 2 can be tightly fixed through the locking bolts, and therefore the blanking position adjusting frames can be conveniently lifted away from the ground and then tightly fixed.

Two transverse sleeves 3-1 are integrally arranged on two sides of the upper end of the cross beam 3 and are sleeved on two sides of the lower end of the inverted T-shaped support rod 2 in a sliding mode, so that the cross beam 3 can perform certain transverse displacement on the lower end of the inverted T-shaped support rod 2 to adapt to the position change of a ridge. The lower end of the cross beam 3 is provided with a sliding groove 3-2, the upper ends of the two vertical rods 4 are in sliding connection with the two ends of the sliding groove 3-2, the lower ends of the two vertical rods 4 are oppositely bent to form wheel shaft parts and are respectively and rotatably provided with ridge positioning wheels 5, the middle position of the lower end of the cross beam 3 is fixedly provided with a bearing seat 3-3, the middle position of the adjusting screw rod 6 is rotatably connected with the bearing seat 3-3, the two ends of the adjusting screw rod 6 are provided with two sections of threads 6-1 in opposite directions, the middle positions of the two vertical rods 4 are respectively and integrally provided with nuts 4-1 and are matched with the corresponding threads 6-1 in a screwing mode, so that the distance between the two vertical rods 4 can be changed through positive and negative rotation of the adjusting screw rod 6, the distance between the two ridge positioning wheels 5 is adjusted to enable the two ridge positioning wheels to be well clamped on the two sides of corresponding ridges, and further move along with the ridges. Because the section of the ridge is generally approximate to an isosceles trapezoid, preferably, the opposite surfaces of the two ridge positioning wheels 5 are set to be conical surfaces with thick centers and thin edges, so that the bottoms of the two ridge positioning wheels 5 can be better kept on two waist lines of the isosceles trapezoid, and the clamping and following movement of the ridge are more stable. In addition, in order to facilitate the rotation of the adjusting screw 6, the handheld turntables 6-2 can be coaxially fixed at two ends of the adjusting screw 6 respectively.

The middle position in front of the cross beam 3 is provided with a strip hole 3-4, the positioning cylinder 7 is vertically arranged and transversely slidably mounted in the strip hole 3-4, the positioning cylinder 7 is provided with a locking screw 7-1 which can be tightly fixed in the strip hole 3-4, the positioning cylinder 7 can be provided with annular wings at the upper end and the lower end thereof in an outward expanding mode so as to limit the positioning cylinder 7 in the strip hole 3-4, the locking screw 7-1 can be arranged at the position, corresponding to the edge of the upper end of the strip hole 3-4, of the annular wing at the upper end, and the relative position of the positioning cylinder 7 and the strip hole 3-4 can be positioned by screwing the locking screw 7-1. Each feed opening 1-1 is connected with a discharge hose 8, the lower end of each discharge hose 8 is inserted and fixed in a corresponding positioning cylinder 7, the position of each positioning cylinder 7 can be fixed in advance according to requirements during operation, if seeding operation is carried out, seeds need to be put in the middle of ridge platforms, the positioning cylinders 7 are also fixed in the middle of the strip holes 3-4, and if topdressing operation is carried out, fertilizer needs to be put beside the seeds/seedlings, so the positioning cylinders 7 are fixed at the edge positions of the strip holes 3-4.

In conclusion, the distance between the two ridge positioning wheels 5 is adjusted by the adjusting screw 6 and stably clamped on two sides of a ridge, the two ridge positioning wheels 5 can move along with the ridge in the advancing process, even if the two ridge positioning wheels 5 bend in the extending direction of the ridge to generate certain transverse displacement, the positioning cylinder 7 fixed with the position on the cross beam 3 in advance can be driven to adapt to the transverse displacement, the relative position of the positioning cylinder 7 above the two ridge positioning wheels 5 is unchanged, and the lower end of the discharging hose 8 is always in the appropriate position when seeds or fertilizers are put in.
