(1) Inspection of technical status

Before the planter works in the ground, it is necessary to check whether the various components are deformed, whether the fasteners are loosened, whether the fastening, transmission, cultivation, and adjustment of the system operation are flexible, and whether the double disk opener or the opener lifting mechanism is deformed.

(2) Adjustment of line spacing, broadcast volume, and marker

The row spacing is determined according to the technical requirements for agricultural production. The number n of openers that can be installed can be calculated as follows:

n=L valid/b +1

L effective: opener mounting effective beam length b: line spacing

If the calculated opener is singular, then the opener in the middle is installed in the middle of the opener mounting frame; if it is even numbered, it is symmetrically installed on both sides with the center of the mounting frame as the symmetrical center.

When the transmission speed ratio is fixed, the seeding amount can be changed by changing the working length of the seeding sheave with the sowing amount adjustment handle. The greater the length of the groove wheel into the seed box, the larger the broadcast volume; otherwise, it is small. According to the requirements of agriculture and production, the actual seeding rate q can be calculated as follows:

q=Mill sowing volume (kg/acre) Ï€ seeder ground wheel diameter (m) Number of rotations of the ground wheel Line spacing (m) (1+ground wheel slip coefficient)/666.7 (kg)

The specific method is to support the seeder so that the seed box is horizontal, the ground wheel can rotate freely, the opener is dropped, and the seed amount adjustment handle is placed in a suitable position. Add - a fixed number of seeds, and include seedlings, and inoculate the inoculation bag under the seedlings. Then, at a speed similar to that of the formal work in the field, 2030 turns of the walking wheel is evenly turned and the amount of seeds in each inoculated bag is weighed. After recording, the actual calculated seeding amount q is compared (the actual calculated ground-slide coefficient - Take 0. 050. 1).

Marker length calculation. In order to make the row spacing of the adjoining two row spacings normal, no replays and missed broadcasts will occur, guiding the tractor to run correctly, and the length L of the marker (distance from the furthest row opener to the marking line). Tractor centerline alignment trace:

L=(B+b)/2

If the tractor is eccentrically driven, the right front wheel of the tractor is often used to align the prints so that the left and right print lengths are different:

L left (B+b)/2+A/2

L right (B+b)/2-A/2

B: broadcast amplitude b: line spacing A: center distance of tractor front wheel

(3) Pilot

Before planter operations, field trials should be conducted first to check and adjust the sowing volume, sowing depth (by adjusting the depth of opener ditching), the quality of the earth covering, the adjoining row spacing, etc., until all the requirements are met. Formal sowing operation.

First calculate the number of return seeding Q (kg):

Q = 2 acres sowing volume (kg) broadcast amplitude (meters) sowing length (meters) / 666. 7

Then add - quantitative seeds in the seed box and scrape them, make a mark, add a round trip of the sowing seeds to the seed box and sowing. After the broadcast-a round trip, see if it is flush with the mark; if not, adjust the position of the adjusting handle, and then perform the trial broadcast until it meets the requirements.

(4) Inspection of sowing quality

It is common to check each metering device with a groove working length template to see if there is any change. Randomly take more than 10 measuring points along the diagonal direction of the plot to check the sowing depth. The deviation should not exceed plus or minus 1 cm. Check the number of seeds actually planted per m length in the broadcast. m,m can be calculated as follows:

m = Mu sowing volume (kg/mu) Row spacing (m) 106/666. 7 thousand grains (g)

After the completion of the plot and the area of â€‹â€‹the plot, check the area sown, the actual seeding rate and the mu planting rate, and adjust if the requirements are not met.
