Description

universal seed meter for seeder

technical field

The utility model relates to agricultural machinery, in particular to a sowing matching machine tool.

Background technique

With the continuous popularization and improvement of the level of agricultural mechanization, seeding machinery is gradually developing towards multi-function. To sow a variety of crops, the seed meter becomes the key. Among the existing seed metering devices, the pneumatic type, the milling type, the hole disc type, and the finger clip type are single-grain precision sowing, which are mainly used for one or a few kinds of crops, and the cost is relatively high; the electromagnetic oscillation type requires additional equipment. The cost is higher. At present, the outer wheel groove (nest) type is mostly used. One or more seeding wheels are installed on one seed metering device. Each seeding wheel has different grooves (nests). According to the needs of sowing, different seeding wheels are selected for operation. Adjust the position of the seed wheel to determine the seeding rate. This structure has low cost and is widely used, but its versatility is not strong, the crop varieties are limited, the sowing amount is not easy to control, the sowing distance cannot be adjusted, and it is easy to cause problems such as seed waste and difficulty in thinning and setting seedlings.

The chain is connected to the driving wheel. The structures of the support, the seed box, the limited seed retaining plate, the seed metering box, the seed metering wheel shaft, the chain, etc. are basically the same as those of the existing seed metering device. The seed box outlet is equipped with a limited seed blocking plate to control the number of seeds flowing into the seed metering box. The sowing rate adjustment rod, the adjusting connecting rod and the adjusting nut are matched with the quantitative seed blocking plate, which is used for multiple groups of seed metering devices to sow the same crop. At the same time, adjust the quantitative seed baffles of multiple sets of seed metering devices to control the sowing amount of the seed metering wheel. The chain is connected with different transmission sprockets to form different rotation speeds of the seeding wheels, which can adjust the plant spacing of the crops. Different sets are equipped with seeding troughs and seeding strips. When multiple groups are used together, multiple crops can be sown at the same time, and it can be carried out simultaneously with the application of base fertilizer.

Manufactured according to the above-mentioned design, the utility model is matched with the seeder, and by adjusting the seeding groove or the seeding bar of the seeding wheel, multiple crops can be sown at the same time or different crops can be sown separately; different sprockets can be connected with the chain , change the rotation speed of the seeding wheel to adjust the sowing distance; move the position of the quantitative seed baffle to adjust the sowing amount. The utility model has the advantages of simple structure, low cost, convenient operation and use, strong versatility, high seeding efficiency and good quality, and better achieves the intended purpose.
