Description

stubble returning machine

Technical field

The invention relates to a stubble-returning machine, in particular to a stubble-returning machine capable of realizing the functions of stubble starting and field-returning at the same time, and belongs to the field of agricultural machinery.

Background technique

At present, the removal of corn stubble is an urgent problem in autumn corn harvesting, especially when combined corn harvesting or conservation tillage techniques are used. At present, when corn is harvested, straw returning to the field has been widely used, and there are not many stubble removal operations, mainly due to mechanical problems. Even if there is stubble removal, the method of stubble removal after returning to the field is adopted, or the field returning machine and the stubble removal machine operate separately to complete the field returning and stubble removal operations, or the straw returning and stubble removal machine can be composed of a field returning machine and a rotary tiller. After the straw is returned to the field, the stubble removal operation is carried out immediately. This type of machine basically puts the straw returning machine and the rotary cultivator behind the machine (suspended on the tractor) at the rear of the tractor (there are also self-propelled ones that place the returning machine in the middle of the machine), and there are tractors or combine harvesters. There is a serious problem with the tire pressure bar, and the cutting effect of the stalks is poor, which cannot meet the agricultural requirements. In order to improve the operation quality, especially the part of the straw that is overwhelmed by the tires, it is necessary to use a high-speed returning motorized knife to remove the stalks from the soil. When it is picked up and shredded, the soil must be cut seriously, which not only causes serious power consumption, but also increases the slip rate of the transmission system due to the obstruction of the soil, causing the cutting speed to drop and affecting the shredding quality.

Use the stubble breaking device that rotates at a slow speed to dig up the corn stubble together with the stalks and send them to the returning machine at the back. The high-speed knife is not in direct contact with the soil, thereby reducing power consumption, and ensuring that the speed of the high-speed knife does not decrease, ensuring the quality of work. It solves the problem of the tire pressing the straw, and realizes the integrated operation of returning to the field and removing stubble.

Contents of the invention

The object of the present invention is to provide a stubble returning machine which can overcome the above defects and realize the functions of stubble starting and returning to the field at the same time.

The technical solution adopted by the present invention to solve the technical problem is: a stubble starting and returning machine, including a gearbox, a tripod, a frame, a stubble starting device cutter shaft, a stubble starting device knife seat, a stubble starting knife, and a stubble breaking knife , Field returning device knife shaft, field returning knife seat, field returning knife, fixed knife, cover, profiling slide plate, stalk feeding inlet. The gearbox is installed on the frame, the tripod is installed on the frame through the suspension ears, the stubble device cutter shaft is installed on the frame horizontally, and the stubble device tool holder is welded on the cutter shaft according to the helical line for installation. Knife and stubble breaking knife, the knife shaft of the field returning device is installed horizontally on the frame, the field returning knife seat is welded on the knife shaft according to the spiral line for installation of the field returning knife, and the cover is installed on the outside of the field returning device through the frame , the fixed knife is welded on the inside of the front part of the cover, the profiling slide is installed on the cover, and the stalk feeding port is installed on the frame. When working, the stubble starting device starts stubble and throws all the straw into the field returning device, and the field returning device returns to the field, realizing the operation of straw starting and field returning at the same time when the machine enters the field at one time.

The stubble starting and returning machine described above combines the functions of stubble starting and returning to the field to form a functional unit. field.

In the described stubble-returning machine, the stubble-starting device knife seat (3) has a backward inclination angle of 10°, the stubble-starting knife (5) is a left and right machete, and the middle part of the blade is in the shape of an Archimedes spiral. The top is arc-shaped, the stubble breaking knife (2) is a straight knife, and the blade is an Archimedes spiral. The arrangement of the two knives is 180 degrees in the same cutting plane, and the arrangement is symmetrical. The stubble device knife Seat (3) is arranged according to helical line, and stubble cutter (5) and stubble cutter (2) are arranged respectively.

In the stubble starting and returning machine, the rotating speed of the cutter shaft of the stubble starting device is 300r/min, and the rotating speed of the cutter shaft of the returning device is more than 1000r/min, and both of them are in reverse rotation.

In the stubble returning machine described above, a profiling slide is installed on the cover of the field returning device for profiling, and the height is adjustable.

The beneficial effect of the present invention is that the stubble starting device and the field returning device are combined to form a functional unit, the stubble starting device starts stubble, and all the straw is thrown into the field returning device, and the field returning device returns the field. It realizes the operation of stubble stubble and field return at the same time when the machine enters the ground at the same time; the angle of the knife seat of the stubble device is 10°, which can effectively avoid grass entanglement, and the type of stubble knife is a left and right machete, which can dig up crop stubble And transport it back to the field returning device, and the middle part of the stubble knife is an Archimedes spiral, and the top is an arc line, which has a strong sliding cutting effect and a better stubble effect. The stubble knife (2 ) knife type is a straight knife, and the blade is Archimedes spiral, which also has a strong sliding cutting effect. The arrangement of the two kinds of knives is divided into 180 degrees in the same cutting plane, symmetrically arranged. Arranged in a spiral line, the stubble cutter and the stubble breaker are arranged separately, and the blades are evenly arranged on the entire length of the cutter shaft and the rotation circumference of the blade. When two adjacent blades are working, the force on the cutter shaft is even, and the cutter shaft does not vibrate when it rotates. ; The rotation speed of the cutter shaft of the stubble device is 300r/min, and the rotation speed of the cutter shaft of the field returning device is above 1000r/min, and both of them are reverse rotation, which not only saves energy, but also throws all the lodging straw into the field returning machine behind Crushing avoids missing cuts; a profiling slide is installed on the cover of the field returning device for profiling, and the height is adjustable to prevent excessive power consumption and rapid tool wear caused by the field returning knife directly hitting the soil.
