A seeder with adjustable furrow depth for peanut cultivation

Abstract

The present invention discloses a seed drill with adjustable furrowing depth for peanut cultivation, comprising a frame, one end of the frame being fixedly connected to a hanger, a first mounting opening and a second mounting opening being provided on the frame near the hanger, the first mounting opening being located between the second mounting opening and the hanger, and a pressing component being fixedly connected to the bottom surface of the frame away from one end of the hanger. In the present invention, the furrowing blade is height-adjustable, thereby enabling adjustment of the furrowing depth. Simultaneously, the height of the ridging plate can be independently adjusted without being affected by the furrowing blade. Regardless of the furrowing blade's depth, the position of the ridging plate can be independently adjusted so that its top surface is located above the soil, preventing the ridging plate from being completely located within the furrow, thereby avoiding ridging failure. The ridging plate is provided with a self-rotating soil-scraping roller, which can break up and loosen the soil surface when sowing in deeper soil, thereby preventing the furrowing blade from becoming stuck when digging deep furrows.

Description

Technical Field

[0001] The invention relates to the technical field of peanut seeders, in particular to a seeder with adjustable furrowing depth for peanut cultivation. Background Art

[0002] Existing peanut planters generally include a seed box, a seeder, and a furrow opener. The peanut planter uses the seeder under the seed box to allow the peanut seeds from the seed box to leak into the peanut furrows opened through the sowing holes of the seeder to complete the sowing operation. Peanuts are annual herbaceous plants, and the optimal growth depth requirements of peanuts in different soils are different. However, the furrowing device on the current peanut planter is fixed in position and cannot adjust the furrowing depth according to the soil quality, which is not conducive to use.

[0003] In this regard, the Chinese invention patent with authorization announcement number CN108012628A discloses a small peanut seeder with adjustable sowing depth. The peanut seeder includes a furrow opener handle including a first connecting handle and a second connecting handle. The first connecting handle is provided with two mounting holes, and the second connecting handle is provided with multiple adjustment holes. Two bolts pass through the two mounting holes and the corresponding adjustment holes respectively.

[0004] The peanut planter adjusts the furrowing depth by adjusting the vertical position of the furrow opener. Two wing plates are set on the furrow opener for ridge forming. The furrow opener and the ridge former are fixed to each other, which is consistent with the current planter structure. However, when adjusting the depth of the furrow opener, the wing plates used for ridge forming will also adjust the height with the furrow opener, and the height of the wing plates cannot be adjusted separately. In this way, when the furrowing is deep, the wing plates are completely located in the furrow and will be buried by the soil, making it difficult to form ridges. Moreover, when the furrowing depth is deep, the soil resistance is large, and it is difficult to cut the soil relying solely on the furrowing blade of the furrow opener, and the furrow opener is prone to getting stuck.

[0005] For this reason, we propose a peanut cultivation seeder with adjustable furrow depth to solve the above problems. Summary of the Invention

[0048] Example 4:

[0049] See also Figure 1-10 , which is the fourth embodiment of the present invention. This embodiment is based on the above three embodiments.
