The operation method for seed loading and fertilizer loading comprises the following steps:
1. screening out fine particles such as broken foam, sandy soil and the like in seeds, picking out large sundries such as weeds, labels, paper sheets and the like in the seeds, cleaning and then loading the scattered and picked seeds, airing the coated seeds, and controlling the moisture content of the soaked seeds or the germinated seeds to be below 50%;
2. checking before seed loading: if the seed cleaning opening cover is covered and the two ends of the seed conveying pipe are connected, the problem is found out in time, and the seeds can be placed after the problem is eliminated.
3. After seeds are added into the seed box 53, the seed box 53 is covered, and the seeds are not opened during operation;
4. the position of the seeds in the seed conveying pipe is observed during operation, when the upper plane of the seeds is close to the bottom of the pipe, the seeds are added in time, otherwise, the seeds are easy to miss seeding.
5. Crushing the fertilizer blocks, removing impurities, and drying the fertilizer with poor over-wet fluidity in the sun in advance;
6. before loading fertilizer, the bucket is checked to see if there is sundries in it, and after loading, the bucket bottom pulling plate is checked to see if it is opened.
Fertilizer and seed cleaning
1. When the fertilizer is cleaned, the fertilizer opening cover at the bottom of the fertilizer hopper is opened, most of the fertilizer flows out from the fertilizer opening cover, and residual fertilizer can be pumped out of the fertilizer opening pull plate to open the fertilizer opening for discharging.
2. When cleaning seeds, the soil stuck on the furrow opener 46 is removed, and a bag is connected below the furrow opener 46. When the door is opened, the seeds can flow out.
Left row stop operation
When the rest rows appear in the operation land, for example, 8 rows are total in the operation land, 6 rows are completed by using a three-row seeder for operation twice, 2 rows are remained, the rest rows appear if the operation is not performed once, and at this time, one or more seeding assemblies 1 need to be stopped to be sown. The product is provided with the clutch on the seeding transmission shaft, and the seeding plate can be conveniently separated from or combined with the transmission system.
It should be noted that, the above-mentioned related data, the selection of the number of teeth and the number of pitches of each sprocket and chain in the present invention are all used to exemplify one of the implementation manners of the hill planter, and the actual operation and production can be adjusted according to the specific seeding conditions, and the adjusted data also fall into the protection scope of the present invention; the technical features are simply changed or obvious technical features are added in the same technology as the working principle of the invention, and the technical features are also in the protection scope of the invention.
