Harvesting machine for root-tuber crop in deep soil layer

Abstract

The invention relates to a harvesting machine for a root-tuber crop in a deep soil layer. Straight growing root-tuber crops, such as Chinese yam, are almost harvested by manual operation, so that the efficiency is low and the cost is high. The existing harvesting equipment has the defects that the soil excavating depth is shallow, and the crop completeness is difficult to guarantee. The harvesting machine comprises a power device, a machine frame, spiral drilling rods, a front conveyor, a conveying bet mechanism and a soil discharging auger, wherein side baffles are fixed to the two sides of the machine frame; the spiral drilling rods are assembled at the lower part of the front section of the machine frame side by side; the front conveyor and the conveying bet mechanism are assembled on the machine frame in sequence, and are joined and matched in tandem to convey and lift the harvested crop and soil to the ground; the soil discharging auger which is connected with the spiral drilling rods and the power device transfers power and evacuates the soil below the machine frame and pushed by the spiral drilling rods backwards. According to the harvesting machine, through mechanical soil loosening and through two-stage conveying of the front conveyor and the conveying belt mechanism, the soil excavating depth is increased, the work efficiency is improved, and the labor intensity and the operation cost of the crops, such as the Chinese yam, are reduced.

Description

technical field [0001] The invention relates to the technical field of harvesting machinery for crops, in particular to a harvesting machine for root crops in deep soil layers. Background technique [0002] Long-root crops such as yam and burdock are rich in protein, amino acids, vitamins and other nutrients, and have high nutritional and medicinal values. However, the rhizomes of this kind of crops are long columnar and fragile in texture. They grow upright in the depths of the soil, and it is impossible to control their growth. When harvesting, the long rhizomes will be broken and damaged if they are not careful. In order to avoid damage to crops during excavation, most yam crops are harvested manually. First, the soil around long rhizomes such as yams is loosened, and then carefully removed. This harvesting method has low work efficiency, great labor intensity, and is time-consuming and labor-intensive, resulting in higher harvesting costs of long-rooted crops, which dir...

Problems solved by technology

This harvesting method has low work efficiency, high labor intensity, and time-consuming and labor-intensive work, resulting in high harvesting costs for long-rooted crops, which directly affects the high price of yams, etc.

[0003] Patent No. ZL 201110034816.2 discloses "yam harvesting and planting dual-purpose machine", which uses devices such as rotary furrow plows to open furrows, and then loosens the soil around the crops through vibration, and then It is pulled out manually; but the operation of the equipment has certain requirements on the hardness of the soil. When the soil is hard, the equipment is difficult to drag normally, and there are certain difficulties in picking up the crops; before the operation, it is necessary to dig down to place the ditch and the operation of the vibration device Pit, cumbersome operation

The "root crop harvester" disclosed in patent No. ZL 201420218049.X solves the excavation work of root crops such as yams to a certain extent, but due to defects in the equipment such as loosening devices, it still has certain impact on soil hardness. In particular, the digging depth is shallow, and crops that are long or planted in deep soil layers cannot be harvested; crops are not transported smoothly during upward lifting operations, and crops are squeezed between crops, crops and soil, and crop damage often occurs. Phenomena, the integrity of yam crops is not easy to guarantee; in addition, the operation mode of the equipment cannot quickly discharge the loose soil in time, resulting in the accumulation of loose soil under the equipment, which increases the walking resistance and affects the travel of the equipment and the depth of excavation. , the driving equipment is difficult to operate, and the soil particles accumulated under the equipment cause great wear and tear on the equipment itself, which seriously affects the service life
