Description

Technical Field

[0001] The utility model belongs to the technical field of agricultural and animal husbandry machinery, and in particular relates to a centralized seeding device for a pneumatic seeder suitable for seeds of different forms. Background Art

[0002] Compared with traditional mechanical seeders, pneumatic seeders use a "one device, multiple rows" seeding method, which can achieve wide-width operation and high work efficiency. It has become an important direction for the development of seeders in my country. "One device" refers to the centralized seeding device. As the core component of the pneumatic seeder, its working effect will directly affect the performance of the seeder. Most of the existing centralized seeding devices can only sow a single type of seeds and have poor versatility. The few seeding devices that can sow two or more types of seeds are either complex in structure or require replacement of parts to sow seeds of different forms. Utility Model Content

[0003] The purpose of the utility model is to provide a centralized seeding device suitable for seeds of different forms in view of the problems and shortcomings of the prior art. It does not need to replace parts. Only by adjusting the displacement adjustment mechanism can the infinitely variable seeding of seeds of different forms and categories under different sowing requirements be achieved, thereby improving the working efficiency and versatility of the machine.

[0004] The purpose of this utility model is achieved through the following technical solutions:

[0005] A centralized seeding device suitable for seeds of different forms mainly consists of a shell, a seeding mechanism, an agitator, a displacement adjustment mechanism and a power transmission mechanism. The seeding mechanism is placed inside the shell, and the seeding shaft of the seeding mechanism passes through the two side plates of the shell and is connected to the two side plates through bearings, and the shaft end on one side of the seeding shaft passes through the bearing and is connected to the fixed plate of the displacement adjustment mechanism, and the shaft end on the other side passes through the bearing and is connected to the power transmission mechanism outside the shell. One end of the agitator is installed on the shell, and the other end is connected to the power transmission mechanism outside the shell. The displacement adjustment mechanism is fixed to the outside of the shell, and the adjustment screw of the displacement adjustment mechanism cooperates with the adjustment nut of the seeding mechanism.

[0006] The seeding mechanism is mainly composed of a seeding shaft, a seeding wheel, a deep groove adjustment sleeve, a shallow groove adjustment sleeve, a seeding bearing seat, a small bearing, a large bearing, an adjustment nut, a seed cleaning brush, a locking block fixed seat, and a locking block. The seeding wheel is installed on the seeding shaft; the deep groove adjustment sleeve is sleeved outside the seeding wheel, and the slots on it correspond to the blades on the seeding wheel; the shallow groove adjustment sleeve is sleeved outside the deep groove adjustment sleeve, and the straight slots on it correspond to the blades on the seeding wheel; the deep groove adjustment sleeve fixing plate is connected through the mounting hole at the small diameter end of the shallow groove adjustment sleeve and the mounting hole on the locking block fixed seat, and the locking block is fixed to the locking block fixed seat by a disc spring and a screw. The inner ring of the small bearing is matched with the seeding shaft, and the outer ring thereof is matched with the bearing seat of the housing. The inner ring of the large bearing is matched with the small diameter end of the shallow groove adjustment sleeve, and the outer ring thereof is matched with the seeding bearing seat. The adjustment nut is sleeved on the small diameter end of the seeding bearing seat, close to the step.

[0007] The deep groove adjustment sleeve is composed of a deep groove adjustment sleeve fixing plate, a deep groove adjustment sleeve sleeve and a slot. The deep groove adjustment sleeve fixing plate is installed in the mounting hole of the shallow groove adjustment sleeve. The deep groove adjustment sleeve sleeve is composed of a sleeve adjustment part and a sleeve installation part. The diameter of the sleeve adjustment part is a fixed value, and the diameter of the sleeve installation part gradually decreases from the end of the sleeve adjustment part. The deep groove adjustment sleeve sleeve is provided with evenly distributed slots, and the number of slots is consistent with the number of seed wheel blades.

[0008] The small diameter end of the shallow groove adjustment sleeve is provided with a mounting hole for mounting the deep groove adjustment sleeve fixing plate. The sleeve of the shallow groove adjustment sleeve is provided with evenly distributed straight slots, the number of which is consistent with the number of the seed wheel blades.

[0009] The utility model has the advantages that the device has a simple structure, can be used for multiple purposes, and has strong versatility. By changing the working end position of the locking block and turning the handle of the adjustment mechanism, the infinitely variable seeding of seeds of different forms can be achieved, and the operation is simple.
