Rape cutter-rower

Abstract

The invention discloses a rape cutter-rower which belongs to the field of agricultural machinery and aims to solve the problem of the mechanized cutting / rowing process for transplanting rape. The rape cutter-rower comprises a rack which can be hung to the front part of a combine harvester, a reel arranged at the front upper part of the rack, and a cutting mechanism and a conveying mechanism whichare driven by a power transmission mechanism, wherein the cutting mechanism comprises a vertical cutting knife and a horizontal cutting knife, the horizontal cutting knife is located at the front lower part of the rack, and the vertical cutting knife is located on one side of the rack; the conveying mechanism comprises a transverse conveyor belt arranged in the middle position of the rack, and a rape discharging hole is formed at the end of the transverse conveyor belt, which is away from the vertical cutting knife; and the conveying mechanism further comprises a transverse shifting mechanismarranged at the upper part of the discharging hole, and a longitudinal shifting mechanism arranged at the rear lower part of the rape discharging hole. Accordingly, by arranging the transverse shifting mechanism and the longitudinal shifting mechanism, the rape cutter-rower can smoothly discharge and row the cut rape in an orderly way, thus avoiding the shattering damage and improving the yield of rape.

Description

technical field [0001] The invention relates to an agricultural machine, in particular to a mechanical device for cutting and drying rapeseed. Background technique [0002] my country is the world's largest rapeseed planting, processing and consuming country. Since 1985, my country's rapeseed planting area and total output accounted for about 30% of the world's rapeseed planting area and total output. However, the level of mechanized harvesting of rape in my country is low and the development is slow. The mechanized harvesting level of rape in my country was only 5.2% in 2006, less than 6% in 2007, and 6.97% in 2008. [0003] Rapeseed mechanical harvesting methods are mainly divided into two types: combined harvesting and segmented harvesting. At present, the diversity of rapeseed planting systems, unsuitability of varieties, imperfect machine performance, and high harvest loss rate all form constraints on combined rapeseed harvesting. It limits the operation area of ​​r...

AI Technical Summary

Problems solved by technology

Its disadvantages are as follows: firstly, the cut rapeseed is sent to the paihekou through a single-belt conveyor. Due to the many branches of the transplanted rapeseed, the diameter of the silique layer is 440-720mm, and the height of the paihekou from the ground is 510mm. The stubble of rapeseed is 150mm, so even though there are conveying teeth installed on the horizontal conveyor belt, the rapeseed cannot be smoothly separated from the conveyor at the mouth of the row, which may easily cause blockage of the outlet

Second, the felled rapeseed is transported to the Paihekou, and after leaving the horizontal conveying mechanism, it is placed on the stubble of the rapeseed. Because the rapeseed has many branches and the stems are intertwined with each other, the laying is not neat, which affects the follow-up. harvest
