Description

A new type of air-blown einkorn wheat precision seed metering device with outer socket

technical field

The invention relates to a sowing machine, in particular to a novel out-socket air-blown precision wheat seed metering device for einkorn wheat, which belongs to the field of agricultural machinery.

Background technique

The plot area for wheat breeding generally has a ratio of 2:1 to 5:1. The length of the community is generally about 3 to 10 meters, and the longest will not exceed 20 meters.

In agricultural scientific research activities, field experiments are often encountered, such as various field comparative experiments, variety comparison yield identification, scientific research workers engaged in the cultivation of new crop varieties, often need to carry out modularized field management of different types of experimental plots, Observe and record. In the case that the sowing amount of each plot is erratic, it is necessary to sow the prepared specified number of seeds completely and evenly in the corresponding plot when sowing, and the plot seeder equipped with an air vertical seed meter The plots that are too large or too small can’t adapt to the situation. If there is no seeder suitable for small plots, we can only use manual ditching, zone division, manually sprinkle a certain amount of seeds in the sowing ditch, and then artificially cover the soil. The amount of labor is large, it is easy to cause artificial misseeding, and the quality of sowing is poor, which directly affects the accuracy of the test.

Therefore, a small precision wheat metering device with high seed filling efficiency and simple structure is designed, which is not only low in manufacturing cost, but also small in size, and can adapt to the agronomic requirements of single seed sowing of wheat in most plots. It not only saves seeds, but also reduces labor costs. Strength is easy to promote and use.

Contents of the invention

In order to solve the above-mentioned technical problems, the present invention designs a novel out-socket air-blown type einkorn wheat precision wheat seed metering device.

In order to realize above-mentioned technical problem, the present invention adopts following technical scheme:

The utility model relates to a novel air-blown precision wheat seed metering device for einkorn wheat, which mainly includes a seed metering device shell, a seed metering wheel, and a seed cleaning sheet. It is characterized in that: the seed metering wheel is installed on the external power square shaft, the seed metering wheel is installed in the shell of the seed metering device, the compound hole of the seed metering wheel is used for filling seeds, and the seed metering wheel is inclined The operation type of the composite hole in the seed guide groove is beneficial to the long axis of wheat seeds entering the hole, and the external air flow enters the seed meter through the air inlet channel of the seed meter shell 2, and the airflow clears the seeds, effectively avoiding seed damage. The housings are connected to each other by bolts.

The operating principle of the above-mentioned novel a kind of einkorn precision wheat metering device is:

The seed wheel is connected to the square shaft of the external power transmission device. When the power appears, the square shaft drives the seed wheel to rotate. Under the guidance of the groove, the seeds enter the composite hole to complete the seed filling process. The filled hole reaches the A of the seed meter housing 2 under the action of the rotation of the seed metering wheel. The seeds filled into the holes are blown away by the airflow, and the filled holes reach the entrance of the seed protection area, and pass smoothly through the area formed by the triangular cut grooves in the housing 2 of the seed metering device and the hole of the seed metering wheel, and reach the seed metering area. The mouth completes the seeding action under the action of seed gravity.

The beneficial effects of the present invention are: the seed metering device has high seed filling efficiency, simple structure, convenient installation, small appearance, low cost, low power consumption, and multiple seed metering devices can be installed on one power output shaft to work simultaneously, greatly improving Sowing efficiency; during the working process, the rotation speed of the seeding disc can also be controlled by adjusting the output speed of the external power transmission device's shaft, effectively controlling the seed distance, and the rate of missed seeding is small, which is convenient for realizing the requirements of wheat breeding hole planting, effectively saving seeds and reducing labor force , improve seeding efficiency.
