Ridging and groove pressing machine for planting shallow rhizoma dioscoreae

Abstract

The invention relates to a ridging and groove pressing machine for planting shallow rhizoma dioscoreae, and belongs to the field of agricultural technologies. The ridging and groove pressing machine comprises a framework, a rotary cultivation ridging assembly and a groove pressing roll. The framework is positioned and supported on land wheels, the rotary cultivation ridging assembly is positioned at the front of the framework, the groove pressing roll is positioned at the rear of the framework, is obliquely supported on the framework in the direction corresponding to ridge shapes formed by means of rotary cultivation ridging and is provided with arc protrusions, and the arc protrusions correspond to arc bottom planting grooves, are peripherally uniformly distributed and axially extend. The ridging and groove pressing machine for planting the shallow rhizoma dioscoreae has the advantages that heavy rotary cultivation ridging and groove pressing operation can be carried out without stop in planting procedures, accordingly, the labor intensity can be relieved to a great extent, and the efficiency can be obviously improved; the ridging and groove pressing machine is favorable for guaranteeing the planting quality, double purposes can be achieved by the single ridging and groove pressing machine with reasonable support structures such as a cutter shaft and the groove pressing roll; only the arrangement of a rotary cultivation ridging cutter needs to be appropriately adjusted, the rotary cultivation ridging cutter only needs to be matched with ridging forming plows, only the corresponding groove pressing roll needs to be exchanged, accordingly, ridging and groove pressing can be carried out on oblique single-side ridge bevel slopes or isosceles triangle double-side slopes as needed, and the ridging and groove pressing machine is quite convenient.

Description

technical field [0001] The invention relates to a crop planting ridge forming and grooving machine, in particular to a yam planting ridge forming and grooving machine, which belongs to the technical field of agricultural planting. Background technique [0002] Yam is a perennial herb with winding perennial roots. It belongs to the genus Dioscorea in the family Dioscoreae. Commonly used traditional methods for yam propagation are the reed head propagation method and the zero-surplus seed breeding propagation method. In the harvesting process of this type of traditional method, the digging pit is deep and easy to break, labor-intensive and time-consuming. Therefore, in recent years, planting in shallow troughs has become a trend. This planting method has changed the growth direction of yams and is conducive to the full mechanization of plowing, planting, management, and harvesting of yams. [0003] Retrieval shows that the Chinese patent literature with application number 20...

AI Technical Summary

Problems solved by technology

The Chinese patent document with the application number 201410681785.3 discloses a special planting method of yam, the staggered planting of yam on the ridge has the disadvantages of reducing the planting density of yam and reducing the yield

The Chinese patent with the application number 201610134324.3 discloses a method of superficial cultivation of purple yam and bamboo in guide grooves. The disadvantages are: 1) the manufacturing cost of bamboo is high, which increases the cost of planting; 2) the output of bamboo is limited, which is not conducive to large-scale cultivation. promotion, and a large amount of bamboo cutting is not conducive to the protection of the ecological environment; 3) The outer diameter of bamboo is different in size, which affects the appearance of yam

[0004] The above existing technologies not only have agronomic shortcomings, but also are not conducive to the realization of mechanization in the planting process, especially the heaviest links such as ridging and grooving, and there is no corresponding mechanization equipment at all.
