A kind of yam harvester

Abstract

The invention provides a Chinese yam harvester, and relates to the technical field of Chinese yam harvesting equipment. A transverse soil conveyor is arranged on a rack, and a ditcher is arranged on the rack and located behind the soil conveyor; the ditcher comprises at least three chain type excavating belts, the width of a Chinese yam ridge is reserved between every two adjacent chain type excavating belts, each chain type excavating belt comprises chain wheels and an annular chain, wherein multiple excavating cutters are arranged on the annular chain, and a ditcher lifting mechanism and a left-right angle adjusting mechanism are arranged further; a vibrator is arranged behind the ditcher; the soil conveyor, the ditcher and the vibrator are connected with a mechanical power device and a hydraulic transmission device; the soil conveyor can convey most soil excavated by the ditcher to the side, and the vibrator can vibrate soil of the Chinese yam ridges. The Chinese yam harvester has the advantages that by means of mechanical excavation, Chinese yam is not missed or impacted, the excavating quality is high, and the harvesting efficiency is high. The Chinese yam harvester is particularly suitable for Chinese yam harvesting and suitable for excavating vertical crops with long roots and stems.

Description

technical field [0001] The invention relates to the technical field of yam harvesting equipment. Background technique [0002] When harvesting long-rooted crops that grow underground, such as yams, in order to avoid damage to yams and affect their quality, most of them are manually excavated, which is labor-intensive and low-efficiency. At present, some harvesters that can help dig trenches and harvest in our country still need more labor, and can only dig out one row of yams at a time, and the work efficiency is also low; most of the existing harvesters are carried out at the bottom of the yams. Vibration loosens the soil and cannot clean the excavated soil well, resulting in the yams still being buried in the soil and cannot be exposed. This not only requires manual digging, but also easily digs out leaks and damages the yams, and the harvesting efficiency is still very low; traditional yam harvesting The machine is driven by people on the car.

[0002] When harvesting long-rooted crops that grow underground, such as yams, in order to avoid damage to yams and affect their quality, most of them are manually excavated, which is labor-intensive and low-efficiency

At present, some harvesters that can help dig trenches and harvest in our country still need more labor, and can only dig out one row of yams at a time, and the work efficiency is also low; most of the existing harvesters are carried out at the bottom of the yams. Vibration loosens the soil and cannot clean the excavated soil well, resulting in the yams still being buried in the soil and cannot be exposed. This not only requires manual digging, but also easily digs out leaks and damages the yams, and the harvesting efficiency is still very low; traditional yam harvesting The machine is driven by people on the car. Because the yam seedlings are small and difficult to see clearly, it is difficult for people to control the digging direction on the car, and it is easy to dig away and scratch the yam.
