[0002] The machinery that sows crop seeds is called planting machinery, that is, sowing machinery. Agriculture is a basic industry related to the national economy and people's livelihood, and sowing operation is one of the six major links in the agricultural production process. Sowing mechanization is the most complex and important work in the agricultural mechanization process. The sowing methods, crop types and varieties faced by sowing machinery vary greatly, which requires sowing machinery to have strong adaptability and work performance that can meet different planting requirements.

[0003] Vegetables refer to plants or fungi that can be cooked and made into food. Vegetables are one of the essential foods in people's daily diet. Vegetables can provide a variety of nutrients such as vitamins and minerals necessary for the human body, and peas are one of them.

[0004] When sowing vegetable seeds, since the sowing depth requirements of each vegetable seed are different, the seeder is required to have an adjustable trenching depth to adapt to the sowing of various vegetable seeds. The seeds after sowing still need to be fertilized, but the fertilizer cannot be applied directly on the seeds, otherwise the seeds will be burned. In response to the above needs, the utility model proposes a pea seeder. Utility Model Content

[0025] Working principle:

[0026] Before planting peas, the user first needs to confirm the depth of the pea furrowing, and then the user drives the adjusting shaft 241 to rotate on the adjusting shaft seat 242 by hand-cranking the handle 244. During this process, the adjusting gear 243 drives the driven gear plate 233 to rotate. Since the number of teeth of the adjusting gear 243 is one-tenth of the number of teeth of the driven gear plate 233, if the adjusting gear 243 rotates one circle, it drives the driven gear plate 233 to rotate one-tenth, so the adjusting push-pull plate 234 also rotates one-tenth, and the push-pull connecting rod 235 pushes and pulls the furrowing arm assembly 22 to rise or fall on the lifting slide assembly 21, thereby achieving the purpose of rising or falling of the boat-shaped shovel furrow opener 25, so that the depth of the boat-shaped shovel furrow opener 25 inserted into the soil is suitable for the planting of peas. After the furrowing depth is adjusted, the handle 244 is turned to tie the rope to fix it.

[0027] When the fiber-drawn vehicle pulls the pea planter to move, the traveling wheel 3 will drive the pea planter to move. In this process, the boat-shaped shovel-type furrow opener 25 will be inserted into the soil to open furrows, and the soil turned out by the furrowing will be turned to both sides of the furrow. In addition, through the transmission cooperation of the seeding box group 4, the fertilizer box group 5, the chain gear on the right end of the traveling wheel 3 and the support gear 6 and the chain 7, the seeding box group 4 and the fertilizer box group 5 are synchronously driven, and the seeding box group 4 will start to discharge pea seeds through the sowing hose and the sowing The pipe head 27 flows into the opened ditch for orderly sowing, and the fertilizer box group 5 will start to fertilize through the fertilizer hose, the first distribution pipe 283 and the second distribution pipe 284 on the fertilizer pipe group 28 to make the fertilizer flow to the turned soil on both sides, and finally the two soil covering arc scrapers 26 scrape the turned soil containing fertilizer from the rear side and cover it into the ditch again. At this time, the fertilizer and the pea seeds will not come into direct contact, which can prevent the pea seeds from being burned by direct contact with the fertilizer, and complete the automatic operation of ditching, planting, fertilizing and covering.
