Description

A plowing and planting machine for returning straw to the field for flooding, drought and stubble removal

technical field

The utility model relates to an agricultural farming machine, in particular to a straw-returning, flood-drought, stubble-removing, plowing and planting machine matched with a Dongfeng-12 walking tractor.

Background technique

In recent years, with the development of the rural economy and the change of farmers' lifestyles, the function of straw as a living fuel has been gradually weakened, which is reflected in the relatively high stubble left during harvesting, and the corresponding agricultural machinery is required to start to have Stubble removal process. But so far there is still a lack of a model for returning stalks to the field for flooding, drought, stubble removal, plowing and sowing, which are matched with the existing Dongfeng-12 type walking tractor. Among the supporting rotary tillers, the 60-type rotary tiller matched with Dongfeng-12 is mainly used. The width of the rotary tiller is only 60cm, which cannot cover the driving wheel track. In recent years, although there have been rotary tillers with a width greater than 800mm matched with Dongfeng-12 walking tractors, they cannot be used for rotary tillage in paddy fields, because the diameter of the tractor's iron anti-skid wheels is larger than that of the rubber drive wheels, and they collide with the rotary tillers. Paddy field operations cannot be implemented. When sowing for stubble removal in dry land, reverse rotation cannot be realized to improve the stubble removal rate.

Contents of the invention

The purpose of this utility model is to provide a kind of supporting Dongfeng-12 walk-behind tractor, and the rotary tillage planter with a tillage width greater than 800mm for returning straw to the field for water, drought and stubble removal. The machine consists of forward rotation transmission hitch box 1, reverse transmission hitch box 2, rotary cultivator gear box and left and right support arms 3, pressure roller 4, fixed cover 5, movable baffle 6, side chain box 9, sowing Box 10, front soil retaining board 11, grass retaining net 12 and other components can carry out multiple operations such as dry field rotary tillage, paddy field stubble leveling, reverse stubble removal and sowing.

When the utility model is used for rotary tillage and sowing operations in dry fields, the rotary tiller is directly connected to the tractor, and the power of the tractor is transmitted to the gearbox of the rotary tiller through the power output gear, and then transmitted to the cutter shaft through the sprocket to realize positive rotation. This state can be used for dry field rotary tillage. For the convenience of realizing the sowing function, the utility model designs the cover of the rotary cultivator as two parts of the fixed cover and the movable baffle. The movable baffle is fixed on the fixed cover during stubble removal and rotary tillage. When sowing, the movable baffle is turned down and fixed at the rear of the fixed cover. The position left by the movable baffle is turned down to install the seed box. The power of the sowing shaft is driven by the tractor. Lead out, drive the seeding shaft through the sprocket chain to realize its seeding function.

The reverse stubble removal and sowing function of the utility model is to add a reverse transmission hitch box 2 between the power output end of the tractor and the gear box of the rotary tiller. At this time, a single-axis gear transmission is used in the hitch box to change the direction of power transmission. , so as to realize the reverse rotation of the knife shaft, and a front retaining plate 11 is installed in front of the fixed casing 5, and the reverse stubble removal, plowing and sowing operations are realized during the movement.

In order to improve the effect of stubble removal, the utility model designs a grass-retaining net at the tail of the mud retaining cover of the rotary tiller. When the stubble is reversed, some plant stubble roots are thrown backward from the top of the rotary tiller. After the design of the grass-retaining net, While the soil is flying backward, the stubble roots in the grass-retaining net can be better buried and pressed into the soil to improve the effect of stubble removal.

When the utility model is performing paddy field rotary tillage operations, because the width of the rotary tiller is greater than the width of the tractor's wheel track, when the utility model is used for paddy field operations, the original rubber drive wheel has been changed into a large-diameter anti-slip wheel, and the anti-slip wheel and rotary tiller The left and right main girders of the tractor form a collision. For this reason, the utility model adds a positive rotation transmission hitch box 1 between the power output end of the tractor and the gear box of the rotary tiller. The direction of transmission remains unchanged. The left and right main girders of the rotary cultivator after installing the hitch box 1 have moved a certain distance, so that the paddy field rotary tillage operation is implemented. In order to improve the leveling effect of stubble in paddy fields, elastically adjustable grass rollers and levelers are installed before and after the tail wheel rides.

Main advantages of the utility model:

The utility model realizes the functions of plowing dry field and paddy field, reverse stubble removal, and rotary tillage seeder in one machine, and has the characteristics of compact structure, complete functions, strong practicability and convenient use.

Detailed ways

When the walking tractor implements rotary tillage in dry fields, the hitch box is not used, and the rotary tiller is directly connected to the tractor. The power output of the tractor is transmitted to the gearbox of the rotary tiller by the gear, and then to the shaft of the rotary tiller through the sprocket. Dry field rotary tillage operations can be carried out during this time.

When the walking tractor performs paddy field rotary tillage operations, since the tractor drive wheel has been transformed from rubber wheels to iron anti-skid wheels, and the diameter of iron anti-skid wheels is larger than the original rubber drive wheel, which hinders the operation of the rotary tiller, it is necessary to install forward rotation transmission The hitch box 1 is connected to the gear of the power output end of the tractor forward, and the gearbox 3 of the rotary tiller is connected backward, so that the rotary tiller can be moved backward properly as a whole, and the forward rotation of the paddy field can be performed without affecting the operation of the iron drive wheel. Tillage work. Elastically adjustable grass pressing rollers and soil scrapers are respectively installed at the front and back of the tail wheel to improve the leveling effect of paddy fields.

The utility model's new reverse stubble removal and rotary tillage sowing function is realized in this way:

The reverse transmission box 2 is installed between the power output end of the tractor and the gearbox 3 of the rotary cultivator. At this time, it is a reverse transmission to change the direction of power transmission, so that the cutter shaft rotates in the opposite direction, and performs reverse stubble removal and sowing operations. Soil retaining plate 11 is equipped with before fixed casing 5 and improves performance of throwing soil. There is a grass-retaining net 12 at the tail of the mud shield of the rotary tiller. When the stubble of the plant is thrown back and upward through the rotation of the cutter shaft during the reverse stubble removal process, the grass-retaining net 12 can block the stubble and make it fall, thereby providing a better environment for rotary tillage. Covered with the soil raised by the machine rotary tillage, the straw is deeply buried while the reverse rotary tillage is sowing, so as to realize the sowing operation of reverse rotation stubble removal.

In the state of realizing the rotary tillage operation, since the rotary tiller cover of the utility model has been divided into two parts, the fixed cover 5 and the movable baffle 6, the position reserved by the movable baffle 6 is just installed with the seed box 10. The power of the sowing shaft of the seeding box is drawn out from the tractor driving wheel, and the sowing shaft is driven by the sprocket and chain to carry out the seeding operation.
