Description

a rotary tiller

Technical field:

The invention relates to tillage machines, in particular to a rotary tiller.

Background technique:

A rotary tiller is a tillage machine that is matched with a tractor to complete plowing and harrowing operations. It has been widely used because of its strong ability to crush soil and flat surface after plowing. The correct use and adjustment of the rotary tiller is very important to maintain its good technical condition and ensure the quality of farming.

A driven soil tillage machine with rotating cutter teeth as the working part, also known as a rotary tiller. According to the configuration of the rotary tiller shaft, it is divided into two types: horizontal axis type and vertical axis type. There are two types of vertical shafts. Horizontal-axis rotary tillers with the knife shaft horizontally placed are widely used. Classification has a strong ability to crush soil. One operation can make the soil finely crushed, the soil and fertilizer can be mixed evenly, and the ground can be leveled to meet the requirements of dry land sowing or paddy field planting, which is conducive to gaining farming time and improving work efficiency. . However, the ability to cover stubble and weeds is poor, the plowing depth is shallow (dry farming 12-16 cm; hydroponic 14-18 cm), and the energy consumption is relatively large. It is mainly used in rice fields and vegetable fields, and is also used in orchard cultivation. The plowing depth of the heavy-duty horizontal-axis rotary tiller can reach 20-25 cm, and it is mostly used for reclaiming shrub land, swamp land and grass wasteland.

Most of the current rotary tillers are installed directly at the rear of the gearbox of the head of the tractor or tiller. For this situation, it will cause great damage to the head and greatly shorten the service life; for plowing After the tractor (walking tractor) is directly installed, farmers can only plow by holding the handle at the tail of the machine head. The manual labor intensity increases and the risk is extremely high. It is easy to scratch people or even die.

Invention content:

In order to make up for the problems in the prior art, the object of the present invention is to provide a rotary tillage machine with a novel structural design, which can conveniently and quickly carry out rotary tillage of soil, reduces labor intensity, has high safety and long service life.

Rotary tillage machinery, including a tractor head, a gearbox is provided on the rear side of the engine of the tractor head, and a supporting plate is provided at the rear end of the gearbox. There is a first transmission box on the pallet, and a rotating shaft passes through the first transmission box. The front end of the rotating shaft is connected with the output shaft of the gearbox through the first steering shaft, and the tail of the pallet is hingedly installed through a connecting rod. There is a rotary tillage frame, and the second transmission box is installed on the end of the rotary tillage frame, the input shaft end of the second transmission box is hinged with the tail of the rotating shaft through the second steering shaft, and the output shaft end of the second transmission box is installed The active bevel gear, the active bevel gear meshes with the driven bevel gear below, the driven bevel gear is set on the rotary tillage shaft, and the rotary tiller shaft is installed on the rotary tillage frame. The upper end of the second transmission box is connected to the A hydraulic cylinder is hingedly installed between the support frames of the seat cushion.

The rotary tillage machine is characterized in that: the rotary tiller shaft is provided with a knife seat, and a blade is installed on the knife seat.

The rotary tillage machine is characterized in that: there are mounting seats on both sides of the supporting plate, a mounting frame is provided under the mounting seat, an adjusting rod passing through the mounting seat is provided at the upper end of the mounting frame, and there are intervals on the adjusting rod. There are a plurality of adjustment holes, locking pins run through the adjustment holes, and rollers are installed at the lower end of the installation frame for rotation.

The above-mentioned rotary tillage machine is characterized in that: mud-proof covers are installed on the rotary tiller frames on both sides of the second transmission box.

The advantages of the present invention are:

The present invention has a novel structural design, and uses the head of the walking tractor to refit, and cooperates with the first transmission box, the second transmission box, the first steering shaft, the second steering shaft, etc. at the tail of the gearbox, and the rotary tillage part Placed at the tail, personnel can directly sit on the seat cushion to operate, which reduces labor intensity and risk factor, and at the same time improves the cleanliness of the machine head, reduces damage, and prolongs the service life.
