Description
Technical Field
The utility model relates to a spiral seed metering device, and belongs to the technical field of seed metering components of agricultural mechanical seeders.
Background
The existing seed metering device has more types, most of complex structures, more parts, high production cost and high failure rate; or the seed discharging holes are less, and the seed sowing machine is not suitable for mechanized large-area sowing.
The utility model relates to a seed metering device (2022230483415) matched with a spiral conveying type seeder, which adopts a double spiral auger to convey seeds from the middle part of a seed metering sleeve, and conveys the seeds to two seed metering ports at two sides of the seed metering sleeve for seed metering, and has simple structure, but only two rows of crops can be sowed at the same time, and the sowing efficiency is low.
Disclosure of Invention
The utility model aims to provide a spiral seed sowing device which has a simple structure, low cost and no maintenance, can simultaneously sow a plurality of rows of crops and is suitable for mechanized large-area sowing.
The utility model is realized by the following technical scheme:
the utility model comprises a seed metering sleeve and a screw rod, and is characterized in that: the screw rod is a single screw rod, the outer diameter of the screw rod is matched with the inner diameter of the seed metering sleeve, the screw rod is arranged in the seed metering sleeve and penetrates through the seed metering sleeve, the screw starting end of the screw rod is a power input end, and a section of connecting section is reserved at the screw starting end and extends out of a port of the seed metering sleeve; a row of seed inlet nozzles are arranged on the outer wall of the seed discharging sleeve at equal intervals along the axial direction of the seed discharging sleeve, a row of seed outlet nozzles with the same number as the seed inlet nozzles are arranged on the opposite side of the seed discharging sleeve at equal intervals along the axial direction of the seed discharging sleeve, and each seed outlet nozzle corresponds to one seed inlet nozzle.
The axis of each seed outlet pipe opening is moved backwards by an integral multiple of a screw pitch compared with the axis of the corresponding seed inlet pipe opening;
the number of the seed inlet nozzles and the number of the seed outlet nozzles on the seed metering sleeve are both more than 2;
the number of the seed inlet nozzles and the number of the seed outlet nozzles on the seed discharging sleeve are optimal in 8-12.
The utility model has the advantages that: the parts are few, maintenance is free, the cost is low, multiple rows of crops can be sowed simultaneously, and the method is suitable for mechanized large-area sowing.

FIG. 1 is a front view of the present utility model;
FIG. 2 is a top view of FIG. 1;
FIG. 3 is a left side view of FIG. 1;
fig. 4 is a perspective view of the present utility model.
In the figure: 1. a seed metering sleeve; 2. a seed inlet pipe orifice; 3. a screw; 4. a seed outlet pipe orifice; 5. and a connecting section of the screw rod.
Description of the embodiments
Referring to fig. 1-4, the utility model comprises a seed metering sleeve 1 and a screw 3, wherein the screw is a single screw rod, the outer diameter of the screw is matched with the inner diameter of the seed metering sleeve, the screw is arranged in the seed metering sleeve and penetrates through the seed metering sleeve, the screw starting end is a power input end, and a section of connecting section 5 is reserved at the screw starting end and extends out of a port of the seed metering sleeve; a row of seed inlet nozzles 2 are arranged on the outer wall of the seed discharging sleeve at equal intervals along the axial direction of the seed discharging sleeve, a row of seed outlet nozzles 4 with the same number as the seed inlet nozzles are arranged on the opposite side of the seed discharging sleeve at equal intervals along the axial direction of the seed discharging sleeve, each seed outlet nozzle corresponds to one seed inlet nozzle, and the axis of each seed outlet nozzle is shifted backwards by an integral multiple of a screw pitch compared with the axis of the corresponding seed inlet nozzle. Generally, the spacing of the seed outlet nozzles can correspond to the row spacing of crops according to the requirement of sowing row spacing, and the number is generally between 8 and 16.
When the utility model is applied, the utility model is arranged on a seeder, each seed inlet pipe orifice is independently connected with a seed box of the seeder by a pipe, each seed outlet pipe orifice is connected with a seed discharging pipe, and the connecting section 5 of the screw rod is connected with a power mechanism of the seeder. During sowing, the sowing machine walks at a certain speed, seeds in a seed box of the sowing machine enter the seed inlet pipe opening along the pipe according to gravity, the power mechanism of the sowing machine drives the screw rod to rotate, so that the seeds falling in the seed inlet pipe opening move to the seed outlet pipe opening along with the screw rod, the seed sowing is realized through the seed sowing pipe, and meanwhile, the seed sowing quantity can be controlled by adjusting the rotating speed of the screw rod.
