Technical background:
application number (2019106547471) technical improvement of solid waste pyramid piling process, which proposes the land reclamation problem of pyramid terrace type hillside; however, for how to transport farm works on the inclined hillside of the multi-storey terrace, the application only mentions in the specification [0016 ]: adopting another patent process, namely a slope engineering material transportation system (certificate No. 1639333); however, the patent is only a single-span cableway transportation method, and the individual-load transportation operation cannot be carried out on each layer of terrace, so that the farm work is very inconvenient; the part load type transportation of terraced fields and hillsides refers to the following steps: the collecting and distributing distance that can adapt to the farming transportation can both set up the stop station at the suitable position in every layer of terraced fields that need load and unload the material and fall the personnel on to make things convenient for the loading and unloading of farming goods and materials and personnel to fall.
A plurality of terrace farming regions of mountain agriculture in China also relate to the problem of farm transport on terraces and hillsides; the current situation is as follows: the automobile transportation method needs the road to bend and turn back, occupies a lot of cultivated land, and most rural areas with scarce land resources do not adopt the mode; the transportation of the tractor on the steep slope can be reluctant to the gentle slope hillside, and can not be done to the hillside with the angle of more than 20 degrees; in the traditional cableway transportation method, the station distance is long, and the method is not suitable for the part load transportation of a multilayer terrace; another disadvantage of conventional cableway transport is: the load and traction are all borne by one steel wire rope, so that the steel wire rope is large in specification, the diameter of a corresponding friction wheel is also increased, the diameter of the friction wheel is over 3.0m, and the heavy equipment is difficult to adapt to farm work in mountainous areas; therefore, terraced field cultivation in many mountainous areas is still an ancient transportation mode of shouldering the back of people, and cannot adapt to the development of modern agriculture.
The application refers to the rail transportation process of mine inclined shafts and slope ramps, but the farm transportation of terraced fields and hillsides has uniqueness: firstly, the conventional slope rail transportation method cannot set vertical curves in the upper direction and the lower direction and cannot adapt to the gradient change of the terrace hillside; secondly, the conventional slope rail transportation method needs to lay a rail on the ground, so that a plurality of terrace lands need to be damaged and occupied; thirdly, materials transported by farming generally have small specific gravity and large volume, the gravity center is too much higher than the rail surface, the materials are easy to get off the rail and turn over laterally during operation, and the stability and the safety are poor; according to the characteristics, the design of the invention adopts: the system is a set of convenient and flexible transportation system with overhead tracks, random slope changing, suspended loading, gravity center reduction, no damage to landforms, no land occupation and no part load stations.
