It should be noted that, without conflict, the embodiments of the present application and features of the embodiments may be combined with each other. The present application will be described in detail with reference to fig. 1 to 9, and examples.
Example 1
Embodiment 1 discloses a seed-metering device of a secondary polymerization acceleration seed metering device, and referring to fig. 1-2, the seed-metering device comprises a seed-metering device shell 101, a seed-metering device top cover 102 and a pressurizing pipe 103. The upper end of the seed distributor housing 101 is disc-shaped, and a plurality of radially arranged insertion holes 1011 are uniformly formed on the outer circumferential surface thereof, 12 insertion holes 1011 in the present embodiment are uniformly formed, and then one seed outlet pipe 104 is provided in each insertion hole 1011. The lower end of the seed divider shell 101 is in a downward contracted arc surface round table shape, a seed dividing channel communicated with each jack 1011 is arranged on the inner wall of the lower end of the seed divider shell 101, and the lower wall of the seed dividing channel is in an arc shape.
The seed divider top cover 102 is detachably and fixedly mounted in an opening on the upper surface of the seed divider shell 101 through a connecting piece, the whole seed divider top cover is of a downwards concave conical structure, a conical surface curve of the seed divider top cover 102 extending into the inner cavity of the seed divider shell 101 comprises an upper curve section and a lower inclined line section, the lower end of the lower inclined line section extends to a conical tip part, the upper end of the lower inclined line section is connected with the lower end of the upper curve section, and the upper end of the upper curve section extends to the position of the inner end of the jack 1011. Through the structural design of the seed divider shell 101 and the seed divider top cover 102, the vortex phenomenon of seed flow in the inner cavity of the seed divider shell 101 under the action of an airflow field can be effectively improved, the blowing speed of the airflow is improved, the seed stagnation phenomenon is improved, and the flow property of seeds is improved.
The important design of this embodiment 1 is the structural design of the booster pipe 103, the booster pipe 103 is an hourglass structure with wide upper and lower ends and narrow middle, and the inner wall of the booster pipe 103 is provided with a V-shaped corrugated structure. The upper end of the booster pipe 103 is communicated with the lower end of the seed divider shell 101, a thread groove is formed in the lower end of the booster pipe 103, the booster pipe 103 can be in sealing rotation on a three-way pipe of a seed supply device through the design of the thread groove, an end ring 1031 is arranged on the outer circular surface of the booster pipe 103 above the thread groove, and after the lower end of the booster pipe 103 is in rotation connection with the three-way pipe, the booster pipe 103 and the three-way pipe can be fastened through a connecting piece on the end ring 1031.
Referring to fig. 3, in the specific design of the booster tube 103, a plane coordinate system is established by taking the central axis of the booster tube 103 as the Y axis and the direction perpendicular to the central axis at the narrowest point of the booster tube 103 as the X axis, and the track curve equation of the two side ends of the section of the booster tube 103 is as follows: Y epsilon [ -100,100], a epsilon [10,40], b epsilon [30,160], unit is mm. In the specific design of this example 1, a was set to 20 and b was set to 62.
Through the structural design of the pressure boosting pipe 103, after the air-seed two-phase flow enters the pressure boosting pipe, the air-seed two-phase flow firstly flows to the middle position of the pressure boosting pipe 103 for secondary polymerization due to the narrowing effect in the middle of the pressure boosting pipe 103, the speed of the air-seed two-phase flow is increased, and the gravity effect of the population is overcome. After the air-seed two-phase flow passes through the narrowest part of the pressurizing pipe 103, the polymerized population is uniformly dispersed around along with the airflow and is decelerated along with the airflow, and the air-seed two-phase flow enters the corresponding seed outlet pipe 104 through the seed distribution channel to realize uniform sowing.
The traditional seed separation device adopting the straight barrel corrugated booster pipe, because the lower end of the booster pipe is connected with the air flow seed feeding pipe on the seed feeding device through the bent pipe, the seed conveying air flow can gather towards one side after being guided by the bent pipe (refer to fig. 6 and 7), so that the seed quantity of the seed outlet pipe at one side end of the seed separation device after the population enters the seed separation device is larger than that of the seed outlet pipe at the other side, and the seed outlet uniformity cannot be ensured. In this embodiment, the hourglass-shaped booster tube is adopted, so that the seed conveying air flows are all polymerized towards the middle and then uniformly dispersed in the process of entering the booster tube through the bent tube, and the seed outlet quantity of each seed outlet tube on the whole seed separating device is effectively ensured to be consistent (refer to fig. 8 and 9).
In addition, due to the structural design of the hourglass-shaped pressurizing pipe, air flow can be polymerized and accelerated at the middle part when entering the pressurizing pipe, and then decelerated after the air flow is accelerated to the maximum. At this time, due to the action of air flow pressurization and acceleration, the gravity of the population is almost negligible compared with the action of high-speed air flow, so that the seed-separating device can uniformly distribute seeds under the complex terrain condition.
To verify the effect of the seed-metering device of the secondary polymerization acceleration-type seed metering device in this embodiment 1 on uniformity of seeding, a comparison test is now performed between the seed-metering device of the secondary polymerization acceleration-type seed metering device of this embodiment 1 and a conventional seed-metering device using a straight-tube corrugated booster tube as a reference group:
The comparison experiments control inlet airflow speed 26m/s, seed supply rate 5000 particles/s, simulation time step length 0.01s and total duration 3s, and statistics of consistency variation coefficients of each row displacement of two types of supercharging pipes under different inclination angles is carried out, wherein the data of specific seed discharge amounts and variation coefficients of each row are shown in the following tables 1 and 2:
Table 1: seed metering quantity of each row
Table 2: coefficient of variation of the consistency of each row displacement
Specific formula of the consistent variation coefficient of each row of displacement:
Wherein:
。
By simulating pneumatic seeding in different ground slope environments through the inclination angles of 0 DEG, 2.5 DEG and 5 DEG, the embodiment has better seeding effect under three inclination angles compared with the existing reference group adopting a straight-tube corrugated booster tube as seen from the calculated consistency variation coefficient of each row of displacement, and particularly, the seeding uniformity of the embodiment is obviously better than that of the reference group after a certain slope appears on the ground.
