Minitype remote-control chain-type tractor

Abstract

The invention discloses a minitype remote-control chain-type tractor. A belt variable speed case is arranged between an engine and a gear box, wherein the engine transmits power to the belt variable speed case by a main clutch and drives two drive sprockets of a crawler by two steering clutches; the main clutch, the middle driving wheel of the belt variable speed case, the steering clutches, agricultural implement lifting and an engine revolving speed control accelerator are all driven by a small hydrocylinder; the small hydrocylinder is controlled by solenoid directional valves, and each solenoid directional valve is provided with a radio frequency remote control receiver and a remote control unit for remotely controlling or manually controlling. The minitype remote-control chain-type tractor can pass through fruit trees and under crowns, can conveniently finish operation items of weeding, loosening the soil, fertilizing and the like and is especially suitable to use in low orchards and greenhouses with thick planting.

Description

Technical field [0001] The invention belongs to the technical field of agricultural machinery, and is a miniature remote control chain tractor that realizes the mechanization of field operations in orchards or gardens. Background technique [0002] At present, the planting of fruit trees in my country mainly adopts the management mode of dwarfing and dense planting. One is that the row spacing of fruit trees is 3~4m. Due to the small row spacing, the existing tractor sprayers, organic fertilizer deep application machines and small orchard management machines are all available. Cannot work normally. Another new planting model orchard has a row spacing of 5-6m. However, due to the large crown shape and small height above the ground, it is still difficult for agricultural machinery to pass operations, especially after fruit trees are produced, the stumps used to support the main branches also affect the performance of agricultural machinery. Passability makes it difficult for tradit...

Problems solved by technology

[0002] At present, my country's fruit tree planting mainly adopts the management mode of dwarf and dense planting. One is that the row spacing of fruit trees is 3-4m. can't work normally

Another new planting mode orchard row spacing reaches 5-6m, but due to the large crown shape and small height from the ground, it is still difficult for agricultural machinery to pass through operations, especially after the fruit trees bear fruit, the stumps used to support the main branches also affect the operation of agricultural machinery. Passability, making it difficult for traditional agricultural tractors to enter orchard operations

Foreign orchard special-purpose tractors generally have relatively large supporting power and high production costs, which are not compatible with the status quo and economic development level of domestic small-scale orchard planting and operation with families as the main body; the development of domestic orchard production machinery is still in its infancy. Less, low technical content, poor compatibility with operating machines, far from meeting market demand
