Punching tool for planting peanuts

Abstract

The invention discloses a punching tool for planting peanuts. The lower part of an operation handle is provided with a connecting plate; the connecting plate is provided with punching pieces; the number of the punching pieces is more than one; the operation handle comprises a fixing rod; the fixing rod is hollow; an adjusting rod is sleeved by the fixing rod; the adjusting rod and the fixing rod are provided with adjusting holes I matching each other; a fixing bolt passes through the adjusting holes I and is fixed by a nut I; the connecting plate is provided with adjusting holes II; one end ofeach punching piece passes through on adjusting hole II for fixing; the adjustment of pit distance can be realized through moving the punching pieces in the adjusting holes II; each punching piece comprises a fixed base column; the lower part of the fixed base column is connected with a base plate; adjusting discs are penetrated by the fixed base column and are fixed by the base plate; the vertical sections of the adjusting discs and the base plate both have a trapezoidal shape; a plurality of the adjusting discs are arranged; and the outer diameter of each adjusting discs is larger than theouter diameter of the base plate. The invention provides the punching tool for planting peanuts; the punching tool has a simple structure and can be used for punching quickly; the punching distance iskept constant; the punching area and depth both can be adjusted; the working efficiency is high; the labor intensity is reduced; and the practicality is high.

Description

technical field [0001] The invention relates to the technical field of agricultural equipment, in particular to a nest-making tool for planting peanuts. Background technique [0002] Peanut is a leguminous crop, one of the main oil species of high-quality edible oil, also known as "groundnut" or "longevity fruit". Groundnuts originate from Rushan, Shandong, and peanuts are annual herbaceous plants. Originated in tropical and subtropical regions of South America. It was introduced into my country in the sixteenth century and developed at the end of the nineteenth century. Now it is planted all over the country, mainly distributed in Liaoning, Shandong, Hebei, Henan, Jiangsu, Fujian, Guangdong, Guangxi, Guizhou, Sichuan and other regions. The fruit of peanuts is a pod, which is usually divided into three types: large, medium and small. The shapes are cocoon-shaped, bead-shaped and hockey stick-shaped. Cocoon-shaped pods mostly have 2 seeds, and bead-shaped and hockey-sha...

AI Technical Summary

Problems solved by technology

[0003] At present, in order to increase the yield of peanuts, ridge cultivation is generally used. During ridge cultivation, nests need to be made one by one. The existing technology generally uses simple enough places to make nests, and only one word can be made. The nesting speed is slow and the labor load is large. , and the density of nest spacing is not easy to maintain, and the size and depth of a single nest spacing are difficult to guarantee, which indirectly affects the yield of peanuts
