Description

A deep ditch fertilizer applicator

technical field

The utility model belongs to the technical field of agricultural and forestry equipment, in particular to a deep ditch fertilization machine.

Background technique

my country's forestry resources are very rich, of which there are no less than 1,000 species of economic trees, and more than 100 species are widely planted. Economic forest is an important part of forestry resources. In order to improve the yield and quality of forest fruit, it is necessary to carry out furrowing and fertilization operations on economic forest trees. Due to the late start of my country's forest land machinery, relatively slow development, low level of mechanized operations, and the complex environment of economic forest land, it is difficult for large-scale ditching machinery to enter the forest land for ditching operations. At present, the ditching of economic forest land in my country mainly relies on manual operations. , low work efficiency and high labor intensity. At present, most orchard ditching machines on the market have a ditching depth of less than 300mm, and large-scale ditching equipment is not suitable for hilly and mountainous forest land operations. For economic forest crops such as Camellia oleifera, the ditching depth is required to be about 400mm, and the forest land is complex and the terrain is poor. Larger, with lush vegetation, more obstacles such as weeds, stones, branches, etc. on the ground, and tree roots underground, the ditching conditions are harsh, and deep ditching (>300mm) is difficult. Therefore, in view of the complex forest environment, harsh ditching conditions, and difficulty in deep ditching (>300mm), a deep ditching fertilization machine was designed to improve the efficiency of ditching and fertilization, thereby promoting mechanized forestry operations.

The ditching machine is a new type of ditching device with high efficiency and practicality. Ditching machine is a common mechanical equipment that can be used in agriculture and municipal construction. Divided into chain trenchers and disc trenchers. The chain trencher is mainly composed of a power system, a deceleration system, a chain drive system and a soil separation system. After the diesel engine transmits the rotation to the clutch through the belt, it drives the travel gearbox, transmission shaft, rear axle, etc. to realize the forward or backward linear motion of the chain trencher. The rotation of the diesel engine in the power system is transmitted to the reduction box in the reduction system through the four-link belt, and then the main sprocket installed on it is driven, and the main sprocket drives the chain meshed with it to rotate. The tool is installed on the chain, and driven by the power system, the chain drives the tool to rotate and translate, so as to realize ditching.

The main working part of the disc trencher is one or two high-speed rotating discs, surrounded by milling cutters, and the milled soil can be evenly thrown to one or both sides according to different agronomic requirements5 On the ground within the range of ~15m, the soil can also be stacked in strips on the edge of the ditch to form a soil ridge. The two discs form an angle of 45° with the horizontal plane, so the section of the ditch is an inverted trapezoid with a wide upper mouth and a narrow bottom. Excavated trenches.

Most of the blades used in existing chain ditching machines are blades of the same structure, which are arranged sequentially according to the direction of travel of the chain, such as CN201050077 discloses a self-propelled chain ditching machine and discloses that the chain is a double chain, which is beneficial The arrangement of the blades and the stability of the transmission, the blades for cutting the soil can be connected to the outer chain plate through bolts, which is convenient for installation and disassembly; the blades are in an arc-shaped structure, which is beneficial to reduce the cutting resistance. The blade block used can conveniently adjust the cutting range of the blade in the width direction, and it is easy to adjust the groove width. CN204690818U discloses a saline-alkali land pipe-burying machine trench ditching device. The three cutters in each group of cutters have different arcs and different inclinations, and along the direction of movement of the chain, The radian of the arc-shaped bending portion gradually becomes larger, and the inclination angle of the blade gradually becomes larger. However, this kind of tool needs to process different types of blades, and the installation needs to be done according to the rules, so the production cost is relatively high.
