Description

Multifunctional peanut planter and method

Technical Field

The invention relates to a multifunctional peanut sowing machine and a method, belonging to the technical field of agricultural machinery peanut sowing.

Background technique

Peanut planter is a commonly used agricultural machinery. Peanut planter can complete the processes of ridging, furrowing, driving ground wheels, fertilizing, sowing, covering, pressing, and film covering at one time. The peanut planter of the prior art is composed of a ridging mechanism, a fertilizing mechanism, a sowing mechanism, a covering and pressing mechanism, a spraying device, a drip irrigation belt laying mechanism, and a film covering mechanism. For example: the disclosed Chinese patent names "A peanut film-covered punch-free planter and method" (application number CN2021110538097), "A peanut automatic film-breaking electric-controlled planter and method" (application number CN2021110776894), etc., are all publicly applied to components on corn planters or peanut planters, but have a single function. At present, the peanut planter with the existing technology has the following problems: 1. Soil moisture problem; if the soil moisture is high during sowing, in order to seize the farming time, a large amount of soil will adhere to the soil covering roller and the soil covering device of the existing peanut planter during operation, causing the pressing roller to press and the mulch film to cover the soil loosely, which cannot play the role of raising temperature and retaining moisture; 2. Labor problem; saving cost means increasing income. During the sowing operation of the existing peanut planter, the peanut mulch film needs to be cut manually and then the secondary mulch sowing operation needs to be carried out. In addition, after the peanuts are sown, the film needs to be broken in time by machines or by humans to harden the seedlings, thereby increasing labor costs; the above problems have an adverse effect on the sowing quality of peanuts and the later peanut yield.
