Scraper transport collection vehicle

Technical Field

The invention relates to the technical field of manufacturing of sugarcane harvesters, in particular to an agricultural machine for collecting and shoveling whole sugarcane stalks.

Background

However, in places with many mountains, the topography of many sugarcane fields is complex, and the fields are scattered, so that the whole sugarcane harvesting operation, especially the field operation, is mostly finished manually, and the efficiency is extremely low. A large number of large-scale combined sugarcane harvesters emerging in the past years are relatively well applied to sugarcane planting areas in vast plain areas, but the large-scale combined sugarcane harvesters are difficult to be effectively applied to Guangxi areas where a large number of sugarcanes are planted, and the large-scale combined sugarcane harvesters are not only high in cost and heavy in whole machine, but are easy to crush the root systems of the sugarcanes and compact the soil of the sugarcane fields at narrow row spacing, so that the annual growth of the sugarcanes is greatly influenced, and the large-scale combined sugarcane harvesters cannot be popularized and applied in multiple mountainous areas. In order to improve the process of mechanical sugarcane harvesting in mountain areas, the applicant continuously improves sugarcane harvesting machinery for many years to improve the mechanical adaptability, so that the sugarcane harvesting procedures which can be completed in the field are divided into harvesting, shoveling, flattening, leaf peeling and collecting, each procedure is completed by designing a relatively small mechanical device, the matching operation of multiple machines in the field is beneficial to improving the sugarcane harvesting efficiency and quality, and the adverse effect on sugarcane fields is reduced. The shoveling and transporting mechanical equipment with the structure is well practiced in actual operation, but the application range of the shoveling and transporting mechanical equipment is still limited by the terrain and the requirement of matching with the special side-lodging harvesting machine. If a user purchases the shoveling and transporting machine independently, the whole sugarcane cut down on the sugarcane field is generally piled in a scattered state in the field due to the growth, cutting direction, terrain and other reasons, and is inconvenient to collect and shovel; or due to the reason of topography, some plots are inconvenient to stop production and cannot scoop up surrounding sugarcane.
