Description

Rear suspension type vertical rotary cultivator of tractor

Technical Field

The utility model relates to a vertical rotary cultivator, in particular to rotary cultivation of a tractor rear suspension type vertical rotary cultivator, which is used for deep ploughing and deep scarification cultivation of powder ridges and belongs to agricultural machinery.

Background

The existing farming equipment mainly has the main effects of carrying out plowing and scarification operation on the land, in order to realize mechanization, the equipment generally uses a tractor as a platform and adopts traditional manners such as plowing, rotary tillage, harrowing and the like to carry out farming, not only is the working procedure complicated, but also the situations of plowing deep and soil breaking are not ideal, and the requirement on the soil is high, most of the farming equipment needs to work on soft soil, the farming depth is shallow, and the mechanized development of agriculture is not facilitated.

The land property of China belongs to the modes of yield covering to households and scattered planting, small horsepower is more in large and multiple farming agricultural machines, soil hardening is caused by long-term shallow ploughing, the drought and lodging resistance of crops is weak, and the yield is difficult to increase.

In order to solve the problem of deep ploughing and soil pulverizing, particularly for root-tuber crops, the vertical rotary cultivators (powder ridge machines, deep scarification machines and the like with larger difference in naming modes) are used in China, and the vertical rotary cultivators are mainly supported by a tractor, a vertical tillage part is arranged on a rear frame of the tractor, a hydraulic oil cylinder and a guide post are arranged on the vertical tillage part, one or more rotary tillage drill rods are arranged below the vertical tillage part, spiral blades are arranged on the drill rods, and angle teeth are arranged on the spiral blades. This machinery utilizes hydraulic cylinder and guide pillar to guarantee that the rotary tillage drilling rod is perpendicular to be buried and guarantee to plough deeply, implements the drill bit and cuts the smashing to soil perpendicularly after burying, moves ahead with the help of traction force, makes the automatic suspension of soil become the ridge. The spiral drilling and milling rod is adopted, the spiral blades are provided with the angle teeth, and although the floating ridges formed by the machine are low, the power consumption is low, and the efficiency is high. There are also special blades screwed on the spiral blades.

Although the above machines have many advantages, the drill rod and the drilling and milling rod are subjected to larger resistance when advancing, so that the characteristics of the drill rod require larger power when working besides the larger power required by deep ploughing, thereby causing the use efficiency of the vertical rotary tiller to be lower. Moreover, massive foreign matters such as stones and stumps can appear in the soil, the vertical rotary tillage drill rod can be damaged due to the foreign matters, and the replacement cost of the rotary tillage drill rod is high, so that the operation efficiency is improved, the damage to the vertical rotary tillage drill rod is reduced, and the vertical rotary cultivator is the biggest obstacle to large-area popularization.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a vertical rotary cultivator which is convenient to refit, short in refit period, small in working running resistance, high in working efficiency, long in service life of a vertical rotary tillage drill rod and low in use cost, and can vertically lift at different tilling depths.

In order to achieve the purpose, the utility model is realized by the technical scheme, the tractor rear suspension type vertical rotary cultivator comprises a rear suspension bracket, wherein a double oil cylinder for enabling the vertical rotary cultivator to vertically move up and down, a first connecting rod and a second connecting rod of a left parallel four-bar linkage and a right parallel four-bar linkage are arranged on the suspension bracket, one end of the parallel four-bar linkage is connected with a gearbox bracket, a stepped deep loosening cutter and a gearbox are arranged on the gearbox bracket, one or more vertical rotary cultivation drill rods are arranged below the gearbox body, the drill rods can be arranged in a front-back mode or a single line mode according to requirements, and the vertical rotary cultivator is input by a tractor through a transmission shaft.

In order to ensure convenient modification, short modification period and vertical lifting of different required tilling depths, the rear suspension mechanism of the original tractor is disassembled, a parallel four-bar oil cylinder control mechanism is adopted, the first connecting bar and the second connecting bar in the left and right parallel four-bar mechanisms are respectively hinged on the rear suspension bracket, one end of the double oil cylinder is fixedly arranged on the rear suspension bracket, and the other end of the double oil cylinder is hinged on the middle point of the first connecting bar or the middle point of the second connecting bar.

In order to reduce the forward resistance of the operation and improve the operation efficiency, and simultaneously avoid the rotary tillage drill rods from directly colliding with the obstacles such as stones, wood and the like to be damaged, a group of deep loosening cutters are additionally arranged in front of each rotary tillage drill rod.

In order to ensure that deep ploughing and pulverizing ridges with different soil qualities can be smoothly carried out, the rotary tillage drill rods are arranged in a triangular front-back manner in principle.

The beneficial effect of above-mentioned scheme is:

by adopting the technical scheme, the rotary tillage machine has the advantages of simple structure, convenience in modification, easiness in adjusting the tillage depth, high operation speed and wide application range, and by adopting the front deepened loosening cutter, the forward resistance of operation is reduced, the operation efficiency is improved, meanwhile, the damage rate of a rotary tillage drill rod is reduced, the service life of the whole machine is prolonged, and the operation maintenance cost is reduced.
