Description

A small rotary tillage all-in-one machine for ridging and forming holes

technical field

The invention relates to a small-sized integrated machine for ridge and hole formation by rotary tillage, in particular to the research field of agricultural machinery requiring ridge formation and hole formation.

Background technique

In the process of planting tobacco and other crops in the field, it is usually transplanted after ridges and holes are formed. This method is conducive to soil moisture conservation and drought resistance, and improves the quality and yield of tobacco. Ridging and forming holes at the same time is a new type of soil preparation method. After plowing, the ridges are straight and the furrows are flat, the soil is finely divided, and the holes are vertical to the ground and have the same depth, which can effectively reduce labor intensity and improve production efficiency.

At present, in our country, in the process of transplanting tobacco into holes, manpower is still the main method. Existing machinery generally has the problems of low hole forming speed and low work efficiency. There is still a lack of all-in-one ridge forming machines suitable for the agronomic requirements of tobacco planting. The traditional operation method of first forming ridges and then using ridge forming machines or manually to form ridges on the ridges increases the operation process, and it is difficult to guarantee the quality of burrowing. The soil is repeatedly rolled, which is not conducive to the growth of tobacco and the cost is high.

The integrated rotary tillage, ridge and hole forming machine can achieve a ridge distance of 1.4 meters, a ridge height of 35 cm, and a uniform width of the ridge body. The holes have the same depth and are perpendicular to the ground, and the hole formation operation is carried out while ridging. It can meet the agronomic requirements of deep planting of tobacco seedlings, and make the soil preparation highly efficient and beneficial.

The lower part of the cavitation rod 13 is wedge-shaped, and its counterclockwise rotation speed is greater than that of the tractor. Vertical square holes can be formed on the ridge.

The working principle of a small-scale rotary tillage ridge-forming integrated machine of the present invention is:

The power of the walking tractor is transmitted to the knife shaft through the gearbox to drive the ridging knife to rotate to complete the ridging action; the ground wheel transmits the power to the caving sprocket box through the sprocket box during the forward process to provide power for the caving mechanism; The sprocket box, the cavitation sprocket box and the cavitation mechanism are all fixed on the gearbox of the walking tractor through the frame; the depth of the hole is controlled by the height of the lifting frame of the cavitation device fixed on the gearbox; The crank-rocker mechanism drives the wedge to form the hole. The connecting rod and the tractor produce anti-phase motion to realize the hole. The hole-forming connecting rod is hinged with the connecting rod in the crank-rocker mechanism, and the movement track of the hinge point moves downward to become the roller guide rail. , the roller on the caving connecting rod moves in the roller guide rail to ensure that the caving connecting rod is always vertically downward. It is said that it can be realized as a vertical square hole.

The advantages of a small-scale rotary tillage ridge forming integrated machine of the present invention: the invention can be connected with a walking tractor to realize ridge formation and hole formation at the same time, and the depth of the formed holes can be adjusted according to requirements; the operation quality is high, The hole depth is consistent, which can meet the agronomic requirements; one person can complete the operation independently, which can effectively reduce labor intensity and improve production efficiency.
