Description

Rotary tillage drill rod of vertical rotary cultivator

Technical Field

The utility model relates to a vertical rotary cultivator, in particular to a rotary tillage drill rod of the vertical rotary cultivator, which is used for deep tillage, deep scarification, soil cutting and ridge smashing 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 modes of plowing, rotary tillage, harrowing and the like to carry out farming, not only has complex working procedures and unsatisfactory plowing depth and soil breaking conditions, but also has higher requirements on the soil, mostly requires working on soft soil and is not beneficial to large-area mechanized production of agriculture.

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 pulverizing soil, 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, one or more rotary tillage drill rods are arranged on the vertical tillage part, spiral blades are arranged on the drill rods, and angle teeth are arranged on the spiral blades. The machine implements that the drill bit cuts and crushes the soil vertically after entering the soil, and moves forward by virtue of traction force, so that the soil automatically suspends to form ridges. 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 machine has many advantages, the drill rod and the drilling and milling rod are subjected to large resistance when moving forwards, so that the deep ploughing needs to be added with large power, and the characteristics of the drill rod also need to be added with large power when working. In use, mainly smash soil through helical blade's outer sword, helical blade is worn and torn easily, in case wearing and tearing are serious, just must change helical blade, because helical blade welds on the main part cutter arbor, changes and must wholly change, and it is troublesome to change, and the replacement cost is high. The special blade for screw connection is simple to replace, but the replacement cost is higher for the special blade. Meanwhile, as the special blade is screwed on the helical blade, the installation angle of the special blade changes along with the change of the helical angle, and the characteristic of the drill rod cannot reduce the advancing resistance.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a vertical rotary tillage drill rod which reduces the running resistance during work, improves the work efficiency, has long service life, is simple to replace a worn part and has low use cost.

In order to achieve the purpose, the utility model provides a rotary tillage drill rod of a vertical rotary cultivator, which comprises a drill rod body, wherein a spiral blade is arranged on the drill rod body, and a cutter seat and rotary tillage blades which are common to the traditional rotary cultivator are equidistantly arranged along a lead below the spiral blade.

In order to reduce the manufacturing cost and the use cost of users and facilitate the installation and the disassembly, the universal cutter holder and the rotary tillage blade of the traditional rotary cultivator are adopted.

In order to ensure the smoothness of vertical soil penetration and small advancing resistance, the helical angle of the helical blade is combined with the helical angles of the drill bit and the end mill to form a milling drill bit.

In order to save labor for cutting soil of the soil cutting section, a mature traditional rotary tillage blade is adopted for cutting soil, and a universal cutter holder is vertical to a drill rod. Not only ensures the smoothness of soil cutting, but also reduces the advancing resistance caused by the properties of the drill rod.

The utility model discloses a rotary cultivator, including the general blade holder of traditional rotary cultivator, rotary tillage blade, draw-in groove, the general blade holder of traditional rotary cultivator with through draw-in groove fixed connection between the rotary tillage blade, the draw-in groove sets up on the general blade holder of traditional rotary cultivator, the draw-in groove is type of ellipse promptly the upper and lower both sides line of draw-in groove is the pitch arc, the installation end of rotary tillage blade also be with the type of ellipse that the draw-in groove corresponds, the rotary tillage blade card in the draw-in groove and run through by the bolt with the general blade holder of traditional rotary cultivator with the rotary tillage blade is fixed. Compared with the traditional rectangular clamping groove, the oval-like clamping groove is adopted, so that the rotary tillage blade and the traditional rotary cultivator general blade holder have larger contact area at the side line, the rotary tillage blade and the traditional rotary cultivator general blade holder are more stably connected, and the corners of the rotary tillage blade and the corners of the clamping groove are not abraded greatly to cause the connection of the rotary tillage blade and the clamping groove to be loose due to long-term high load in long-term use.

The beneficial effect of above-mentioned scheme is:

by adopting the technical scheme, the utility model has the advantages of simple structure, convenient assembly and disassembly and practicality, and can be used for crushing soil and deeply ploughing and deeply loosening the soil. Different traditional rotary tillage blades are adopted according to different soils and are perpendicular to the cutter bar, so that the resistance of soil cutting during advancing can be reduced, and the crushing quality and efficiency are guaranteed. The helical blade mainly plays a role in guiding soil, and the service life is greatly prolonged.
