Description

A telescopic compartment of an orchard freight car

technical field

The invention relates to the technology of orchard freight cars, in particular to a retractable car for orchard freight cars.

Background technique

The proportion of fruit output value in my country's agricultural output value is constantly increasing, but the mechanization of fruit production is obviously lagging behind, and the orchard transportation tools are particularly prominent. For example, 90% of the citrus fruits in my country are planted in hilly and mountainous areas with complex terrains. However, the transportation of fruits and agricultural materials in the process of planting and harvesting is still dominated by human transportation, with low production efficiency and high labor intensity. In recent years, my country has also made breakthroughs in the field transportation technology of mountain orchards. The main technologies include aerial transportation cableways and track forms. These two transportation technologies provide a solution for the transportation of agricultural materials and fruit in steep mountain orchards. In addition, for orchards on gentle slopes with high planting density and poor road conditions, micro crawler trucks with good trafficability, strong mobility and easy operation are undoubtedly a better choice. At present, the compartments of miniature tracked freight vehicles are generally designed with fixed dimensions, and the effective volume of the compartments is a fixed value. Under the condition of a certain rated loading quality of the freight vehicle, the loading mass utilization factor depends on the volumetric mass of the cargo (kg m ^-3 ) That is, the density of the goods. When loading sand and stones with high density, the loading quality of the freight car can be fully utilized, and the utilization factor of the loading quality is high. On the contrary, when the fruit with low density is loaded, the loading quality of the freight car cannot be fully utilized. , the loading mass utilization factor is low.
