Lifting adjusting straw smashing device

Abstract

The invention discloses a lifting adjusting straw smashing device which comprises a lifting frame, a plurality of straw smashing devices are arranged on the lifting frame side by side, the lifting frame is arranged on a first-stage lifting mechanism, and the first-stage lifting mechanism is movably connected with a second-stage lifting mechanism. And a driving mechanism for adjusting the height of the lifting frame is arranged between the second-stage lifting mechanism and the lifting frame. The height of the lifting frame is adjusted through the driving mechanism, then the distance between the straw smashing device and the ground is adjusted, it is guaranteed that rhizomes are not damaged, stubbles on the rhizomes are shorter, later-stage manual work is reduced, and the quality of rhizome finished products dug out in the later stage is high. When the tractor drives the straw smashing device to move in the field, the straw smashing device is lifted to the highest position through the two-stage lifting mechanism, the straw smashing device is prevented from being damaged by obstacles such as branches and ridges, the safety of the machine tool is improved, and the turning radius of the machine tool is reduced.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a lifting-adjusting straw crushing device. Background technique [0002] For rhizome crops, it is necessary to remove the seedlings that will grow on the ground before harvesting, so that the rhizomes are exposed, which is convenient for harvesting. For relatively shallow rhizome crops, some rhizomes and stems are exposed on the soil surface. The existing seed killer blades can break up weeds or seedlings, and at the same time easily damage the exposed rhizomes. In order not to damage the exposed rhizomes, the It is often necessary to raise the killing position of the seedling machine, but the height of the stubble increases, and the straw on the stem is not cleanly crushed, which is not conducive to subsequent soil separation and processing. The existing knapsack brush cutter can cut grass by hitting the grass rope, and can also be used for straw killing and crus...

AI Technical Summary

Problems solved by technology

For relatively shallow root crops, some rhizomes and stems are exposed to the soil surface. The blades of the existing rice seedling machine can break the weeds or seedlings, and it is also easy to damage the rhizomes in the exposed soil. In order not to damage the exposed rhizomes, It is often necessary to raise the killing position of the seedling killing machine, but the stubble height increases, and the straw on the stem is not crushed cleanly, which is not conducive to subsequent soil separation and processing

The existing knapsack brush cutters can mow grass by means of mowing rope, and can also be used for straw cutting and crushing. However, the brush cutter has only one working head, and the height needs to be manually adjusted up and down during the operation. In order to break all the stalks, the labor intensity of the operators is high and the work efficiency is low.
