Inclined spoon wheel seed meter corn precision seeder

technical field

The utility model belongs to the technical field of sowing machinery, in particular to a corn precision sowing machine with an inclined spoon wheel seed metering device.

Background technique

The currently used corn seeder includes a frame with a fertilizer box and a seed box, a fertilization opener and a fertilization pipe on the front beam of the frame, and a sowing opener and a spoon wheel for seeding on the rear beam of the frame. The sowing assembly is composed of a device, a cover device and a pressing wheel. The scoop wheel seed metering device of this kind of corn seeder is installed vertically on the sowing assembly of the rear beam of the frame, and the seed has only one fulcrum on the seed scoop of the spoon wheel seed meter device. If it is tilted, large seeds are easy to fall off from the seed spoon, causing holes and affecting the emergence rate of sowing.

Utility model content

The technical problem to be solved by the utility model is to provide a corn precision sowing machine with an inclined scoop wheel seed metering device that the seeds are not easy to fall off from the seed scoop.

In order to solve the above-mentioned technical problems, the technical scheme adopted by the utility model is as follows: it includes a frame provided with a fertilizer box and a seed box, the front beam of the frame is provided with a fertilization ditch opener and a fertilization pipe, and the rear beam of the frame is provided with a sowing ditch opener 1. A seeding assembly composed of a spoon wheel seed meter, a soil covering device and a pressing wheel, wherein the spoon wheel seed meter is arranged obliquely.

Its additional technical features are: the included angle between the central axis of the spoon wheel seed metering device and the horizontal plane is 8°-40°;

The bottom end of the fertilization ditch opener is 10-15 cm lower than the bottom end of the sowing ditch opener, and the fertilization pipe behind the fertilization ditch opener is provided with 3-5 fertilizer outlets from top to bottom.

When the corn precision seeder provided by the utility model is sowing, the frame moves forward with the tractor, and the fertilization opener is used to open the ditch first, and the fertilization pipe is used to fertilize in layers, and then the ditch opener is sown. Digging is carried out at about 5 cm behind the fertilization ditch opener, and then the seeds in the seed box are discharged through the spoon wheel seed metering device, then the soil covering device is used for covering soil, and finally the pressing wheel is used for repression. The utility model provides the tilting spoon wheel seed metering device corn precision sowing machine, the spoon wheel seed metering device is installed obliquely on the seeding assembly of the rear beam of the frame, so that the center of gravity shifts, and the fulcrums of the seeds on the seed spoon are two , The stability is greatly improved. When the machine shakes or tilts, the seeds are not easy to fall off from the seed spoon, thereby reducing the cavity and improving the seedling emergence rate. According to needs, the angle between the central axis of the scoop wheel seed metering device and the horizontal plane is 8°-40°. The bottom of the fertilizing ditch opener is 10-15 cm lower than the bottom of the sowing ditch opener, which becomes semi-submerged. The fertilization pipe behind the fertilization ditch is provided with 3-5 fertilizer outlets from top to bottom. Fertilization can be applied in layers, which can provide sufficient fertilizer nutrients for corn in different growth stages.

Detailed ways

Below in conjunction with accompanying drawing, the specific structure of the utility model inclined scoop wheel seed metering device corn precision sower is further described.

As shown in Figure 1, the utility model inclined spoon wheel seed metering corn precision sowing machine includes a frame 1, which is provided with a fertilizer box 2 and a seed box 3, and the front beam of the frame is provided with a fertilization ditch opener 4 , fertilization pipe 5, the frame rear beam is provided with sowing opener 6, spoon wheel seed metering device 7, soil covering device 8, the sowing assembly that suppressing wheel 9 forms, and fertilization ditch 4 bottoms are lower than sowing ditch 6 bottoms The end is 10-15 centimeters lower, and the fertilization pipe 3 is provided with 3-5 fertilizer outlets 10 from top to bottom. As shown in FIG. 2 , the scoop wheel seed metering device 7 of the prior art is vertically arranged, and the fulcrum 13 of the seed 11 on the seed scoop 12 is only one. As shown in Figure 3, the spoon wheel seed metering device 7 of the utility model is arranged obliquely, the included angle between the central axis 14 axis of the spoon wheel seed metering device 7 and the horizontal plane is 8°-40°, and the seeds 11 are on the seed spoon 12 The fulcrum 15 is two.

When the inclined spoon wheel seeder provided by the utility model is sown by the corn precision sower, the frame 1 moves forward with the tractor, and the fertilization opener 4 first ditches and fertilizes in layers by the fertilization pipe 5, and then sows Ditch opener 6 ditches at about 5 centimeters behind fertilization ditch opener 5, then the seed in seed box 3 is discharged through spoon wheel seed metering device 7, then soil covering device 8 covers soil, and finally pressing wheel 9 suppresses. In the inclined scoop wheel seed metering device corn precision sowing machine provided by the utility model, the spoon wheel seed metering device 7 is arranged obliquely on the seeding assembly of the frame rear beam, so that the center of gravity shifts, and the fulcrum of the seed 11 on the seed spoon 12 15 is two, and the stability is greatly improved. When the implement shakes or tilts, the seed 11 is not easy to fall off from the seed spoon 12, thereby reducing the cavity and improving the seedling emergence rate. According to requirements, the included angle between the central axis 14 axis of the spoon wheel seed metering device 7 and the horizontal plane is 8°-40°. And the fertilization ditch opener 4 bottoms are 10--15 centimeters lower than the seeding ditch opener 6 bottoms, become semi-submerged pine, and the fertilization pipe 5 is provided with 3--5 fertilizer outlets 10 from top to bottom, can divide Layer fertilization can provide sufficient fertilizer nutrients for corn in different growth stages.

The scope of protection of the utility model is not limited to the above-mentioned embodiments, as long as it has the same structure as the tilting spoon wheel seed metering device and corn precision seeder of the utility model, it falls within the scope of protection of the utility model.
