Description

Rotary tillage beater

technical field

The utility model relates to a rotary tillage beating machine, which can complete rotary tillage and beating operations at one time, and can also be used for separate rotary tillage.

Background technique

Rotary cultivator is a kind of plowing machine with strong practicability and wide application range. It has the characteristics of good soil cutting effect and strong soil crushing ability. Intensive farming requirements. At present, rotary tillers are widely used in our country, accounting for 80% of the mechanization of rice production in the south. It is also widely used in dry field cultivation and land preparation operations such as rapeseed and flue-cured tobacco planting. Especially in recent years, with the adjustment of the planting industry structure in southern my country's rice-producing areas, the intercropping area of rice, wheat, rice oil, rice tobacco, etc. has increased rapidly, which puts forward higher requirements for land preparation machinery, which can not only complete dry land operations and deep plowing , broken soil, leveling and other requirements, and can meet paddy field pulping and paddy field leveling operations.

The rotary tillers currently used in the market are mainly suitable for dryland rotary tillage operations. Due to the shape of the rotary tiller blades and the arrangement of the blades, the quality and efficiency of the multiple tillage operations in paddy field operations are far inferior to paddy field beating; paddy field beating The operation quality and efficiency of soil crushing, pulping, grass pressing, and leveling can meet the technical requirements of paddy field agronomy, but the soil crushing efficiency, rotary tillage depth and comprehensive performance when used in dry land operations are not as good as those of dry land rotary tillers. The utility model integrates the structural features and operating characteristics of the rotary tiller and the beater, realizes the combination of rotary tiller and beater, and one machine with multiple functions.

Utility model content

The technical problem to be solved by the utility model is to provide a rotary tillage beater, which can not only meet the requirements of deep plowing, soil breaking and leveling in dry land, but also satisfy paddy field pulping and paddy field leveling operations.

The technical scheme that the utility model solves technical problem is designed as follows:

A rotary tillage beater is mainly composed of a frame, a transmission system, a rotary cutter shaft, a tillage depth adjustment device, an upper shield, a support frame, a sub-support plate, a rubber plate, comb teeth and a comb plate, and is characterized in that : The shaft of the rotary tiller is made of seamless steel pipe, and the shaft is welded with a cutter head and several knife holders. There are holes with equal intervals on the disk, which is convenient for adjusting the relative position of the blades according to the requirements of agricultural technology; the cutter head is equipped with an anti-winding rod; the frame is composed of a suspension frame, a middle gear box, a left main beam, a right The main beam, the side transmission box and the right side plate are composed; the middle gear box is supported by the left and right main beams; the transmission system is transmitted from the power output shaft of the tractor to the middle gear box through the universal joint, and then through the left main The transmission shaft in the beam drives the cutter shaft to rotate through the side transmission box.

When the rotary tillage beater is working, the rotary tiller blade is driven by the power output shaft of the tractor to make a rotary motion on the one hand, and on the other hand to move forward in a random group to make a constant speed linear motion. It can complete dry land operations such as deep plowing, soil breaking, and leveling.

As the unit keeps moving forward, the blades and comb teeth continuously loosen and crush the cultivated land. The working rotation of the anti-winding rod can prevent the grass from entanglement with the cutter shaft and improve the working efficiency of the operation. The comb board can press the straw and vegetation floating on the soil surface into the mud. The sub-pallet can flatten the seam during the back and forth operation. It has achieved the effects of crushing soil, pulping, grass pressing and leveling.

The utility model integrates the structural features and operating characteristics of the rotary tiller and the beater, realizes the combination of rotary tillage and beating, and one machine with multiple functions. It is suitable for the cultivation of paddy fields and also suitable for the cultivation of dry land. Reasonable structure, high body rigidity, low power consumption, high stubble burying rate.
