Chain type furrow opener and crawler type furrow opening fertilizer applicator

Abstract

The invention discloses a chain type furrow opener and a crawler-type furrow opening fertilizer applicator, the furrow opener comprises: a driving mechanism on which a first output shaft and a second output shaft are arranged at an interval; the chain type ditching assembly is rotationally connected to the first output shaft and is in transmission connection with the first output shaft, and a lifting swing arm is fixed to the position, close to the first output shaft, of the chain type ditching assembly; one end of the first dumping auger is fixedly connected with the tail end of the first output shaft; one end of the second dumping auger is fixedly connected with the tail end of the second output shaft; a cylinder barrel of the pushing oil cylinder is hinged to one side of the top of the driving mechanism, and the telescopic end of the pushing oil cylinder is hinged to the lifting swing arm. During ditching, the first soil discharging auger and the second soil discharging auger discharge discharged soil to one side of a groove, the soil discharging effect is good, and the problem that the soil easily covers the groove, and consequently the fertilization quality is affected is effectively solved; chained ditching is adopted, and the pushing oil cylinder is matched, so that the furrow opener is suitable for deep application of organic fertilizer.

Description

technical field [0001] The invention relates to the technical field of orchard fertilizer spreaders, in particular to a chain type trench opener and a crawler type trench opener and fertilizer spreader. Background technique [0002] Spatial variability of soil fertility and scientific fertilization methods lead to obvious differences in crop yield, quality and benefit. Precisely increasing the application of organic fertilizers and reducing the application of chemical fertilizers are the key scientific and technical issues for soil improvement, quality and efficiency improvement in orchards. The main methods of fertilization in orchards are: ditch fertilization, digging fertilization, whole orchard spreading, irrigation and fertilization; among them, digging fertilization work efficiency is low, the utilization rate of whole orchard fertilizing fertilizer is low, and the investment in irrigation and fertilization facilities is large. The fertilization method is most suitabl...

Problems solved by technology

[0004] However, the ditch opener on the existing orchard ditching and fertilizing machine has a shallow ditching depth, which is not suitable for deep application of organic fertilizers. In addition, the soil after ditching is easy to cover the ditch, which affects the quality of fertilization. When the ditch opener is working, the discharged soil will continue to accumulate, and it will easily form a larger soil pile, which will increase the forward resistance of the ditch opener, which will consume more power of the ditch fertilizer applicator, which will lead to the consumption of equipment. The oil quantity is increased; in addition, the existing ditching and fertilizing machines generally use tractors for traction, which makes the overall length of the machine tools longer, resulting in poor obstacle avoidance and steering capabilities, and is not suitable for complex terrain environments. The fertilizer applicator and the tractor are connected by a traction frame floating, which makes the driving stability of the ditching fertilizer applicator poor, and it is easy to swing from side to side, resulting in the trenches being not straight lines, which reduces the quality of ditching. The fertilizer tank of the traction ditching fertilizer applicator is generally small in size and needs to be filled with fertilizer many times, which is inconvenient to use and requires manual driving for fertilization operations. The degree of automation is low, and it is not suitable for the operating conditions of unmanned intelligent agriculture.
