Vibratory layering fertilization furrower with staggered four rods

Abstract

The invention discloses a vibratory layering fertilization furrower with staggered four rods and belongs to agricultural machinery. The vibratory layering fertilization furrower is characterized in that a main furrower is fixed in a main frame, the main frame is hinged to a tail furrower through left and right ring connecting rods, the left ring connecting rods are connected with adjusting holes of the main frame through adjusting bolts, a vibrating blade with high front and low rear is hinged to the rear of the main furrower, and the rear of the vibrating blade is connected to an orifice plate fixed at the rear of the lower middle of the main furrower through a split pin, a dowel and a spring. By changing the selective connection of the adjusting bolts and adjusting holes, it is possible to transversely control the fertilization position of the main and tail furrowers longitudinally parallel so as to decrease soil tilling resistance and its lateral component; through passive vibratory soil cutting by the vibrating blade, soil of the furrow wall behind deep fertilizer is forced to collapse, covering the deep fertilizer, and the fertilizer is separated in layers significantly. The vibratory layering fertilization furrower with staggered four rods is novel in structure, simple and reasonable, convenient to operate, good in quality and reliability, and highly applicable.

Description

technical field [0001] The invention belongs to agricultural machinery, and mainly relates to a dislocation four-rod vibrating layered fertilization opener equipped with a seeder. Background technique [0002] At present, in order to meet the nutrient requirements of the entire life cycle of intertillage crops, in addition to applying seed fertilizer while sowing, it is also necessary to apply base fertilizer before sowing, and intertillage topdressing in the middle of crop growth. The machine tool enters the field many times, and the plowing and compaction of the soil will cause soil compaction, shallowing of the plow layer, and soil degradation, which will affect the sustainable development of agriculture. It is easy to cause the volatilization and loss of chemical fertilizers and reduce the utilization rate. Relevant studies have pointed out that: at the same time of sowing, layered and deep application of slow-release long-acting fertilizer can significantly increase cr...

Problems solved by technology

However, most of the commonly used layered fertilization openers currently use a single opener co-located layering method. Due to the poor fluidity of the soil, the layering effect is not obvious, and the fertilizer in the shallow layer mostly falls into the deep layer, and the spatial distribution of fertilizer is uneven. , and the layered fertilizer applicator of the proportional layered fertilization device invented by the inventor can realize and complete the functions of deep and shallow layered fertilization or frontal layered and lateral layered fertilization by using a special suit tail pipe structure. The same problem of inconspicuous delamination as mentioned above occurs in the layer, but when using side layering for layered fertilization, the suit tailpipe is arranged in the side and rear direction, and the overall asymmetric structure of the opener increases the soil tillage resistance on the one hand. , on the other hand, it produces a large lateral tillage resistance
