How Does Corn Sheller Work?

Recommended Posts

(1) Inspection of technical status

          Before the Knapsack Fertilizer Machine goes to work, check whether the various parts are deformed, whether the fasteners are loose, whether the fastening, transmission, cultivation, and adjustment systems are flexible, and whether the double-disc opener and the lifting mechanism of the opener are deformed.

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

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

   n=L effective/ b +①

   L effective: effective beam length of the opener mounting frame b: row spacing

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

   When the transmission speed ratio is fixed, use the sowing amount adjustment handle to change the working length of the seeding groove wheel to change the sowing amount. The longer the slot wheel enters the seeding box, the larger the seeding volume; otherwise, the smaller. According to the requirements of agriculture and production, the actual seeding amount q can be calculated according to the following formula:

   q = sowing rate per mu (kg/mu) × π × Knapsack Fertilizer Machine wheel diameter (m) × number of turns of the wheel × row spacing (m) (1 + wheel slip coefficient) / 666.7 (kg)

   The specific method is to support the Knapsack Fertilizer Machine, make the seed box level, the ground wheel can rotate freely, put down the opener, and place the sowing amount adjustment handle on the appropriate position. Add a certain amount of seeds, and include a flat seed surface, and connect an inoculation bag under the seed tube. Then, at a speed similar to the official field operation speed, evenly rotate the walking wheel 20-30 times, weigh out the amount of seed in each inoculation bag, and compare it with the actual calculated sowing amount q after recording (the actual calculation of the wheel slip The coefficient is generally taken from 0.05 to 0.1).

   Marker length calculation. In order to make the row spacing of the two adjacent row spacings normal, avoid replay and missed sowing, and guide the tractor to drive correctly, the marker length L is aligned with the centerline of the tractor: L=(B+b)/2

For example, when the tractor is driving off-position, the front right wheel of the tractor is often aligned with the mark, so that the length of left and right marks are different: Lleft(B+b)/2+A/2, Lright(B+b)/2 -A/2, B: sowing width b: row spacing A: tractor front wheel center distance

(3) Trial broadcast

Before Corn Sheller is operated, field trials should be carried out, and the seeding rate, seeding depth (to be achieved by adjusting the depth of the trench opener), soil quality, adjacent row spacing, etc. should be checked and adjusted until all items meet the requirements. Carry out formal planting operations.

   First calculate the seed quantity Q (kg) that should be sown in one round trip: Q=2 mu sowing amount (kg) × sowing width (m) × sowing stroke length (m)/666.

          Then add a certain amount of seeds in the seed box and scrape them flat, make a mark, and add a round trip of the seed to be sown into the seed box for sowing. After playing a round trip, see if it is flush with the mark; if it is inconsistent, adjust the handle position appropriately, and then perform trial broadcast until it meets the requirements.

(4) Inspection of seeding quality

   often use the groove wheel working length template to check each meter to see if there is any change. Randomly select more than 10 measuring points along the diagonal of the plot to check the seeding depth, and the deviation shall not exceed plus or minus 1 cm. Check the actual seeded number m per meter length in the sowing line, m can be calculated as follows:

  M = sowing rate per mu (kg/mu) × row spacing (m) × 106/666. 7 thousand-grain weight (g)

   Corn Sheller manufacturer: After sowing a certain plot and a certain area, check the sown area and the actual sowing amount with the sowing amount per mu, and adjust if it does not meet the requirements.
