Description

Paddy field straw burial rotary tiller

technical field

The utility model relates to a paddy field straw burying rotary cultivator for paddy field straw burying, soil crushing and straw covering operations.

Background technique

In recent years, with the rapid development of the rural economy and the level of mechanization, the effective utilization rate of crop straw has been declining year by year, especially in rice-wheat rotation areas, where the wheat straw and high stubble scattered after the operation of the combine directly affect the planting of rice. However, most farmers use the method of burning straw, which seriously causes waste of resources and environmental pollution. At present, most of the paddy field straw returning machines popularized and applied in our country have problems such as complex structure, high price, poor operation effect, low utilization rate of machines and tools, and poor economic benefits.

Contents of the invention

In order to solve the problems existing in the current rice and wheat harvesting, the utility model provides a paddy field straw burying rotary cultivator, which can carry out operations such as paddy field straw burying, crushing soil and covering straw after replacing the paddy field grass burying tool , The machine works well, can reduce costs, improve the effect of grass burying, reduce the workload, one machine with multiple functions, improve work efficiency and improve machine functions.

The technical scheme adopted by the utility model to solve its technical problems is: the machine has a plate-shaped left and right support arm, a coulter transmission box, a left side plate, a chain box assembly and a fender combination welded and fixed, assembled into a A rectangular frame, the coulter transmission box is installed above the middle of the frame, the joystick protrudes from one side of the coulter transmission box to the rear, the coulter transmission box is connected with the transmission shaft of the tractor to input power, the coulter transmission box It is installed and rotated synchronously with the sprocket of the chain box assembly on the right, and is connected with the drive wheel of the rotary tiller on the cutter shaft and the paddy field burying knife through the chain to realize straw burial, rotary tillage and broken soil operations, and the rotary tillage and the rear The thrown soil blocks are dragged by the fender, the cover and the drag plate to make the land level, and the function of leveling the land can be realized. The rotary tiller and paddy field burying knife are symmetrically fixed on the rotary tiller shaft, and the left and right paddy fields The angle between the two welds of the grass cutter is in the range of 65° to 75°. On the outer diameter of the shaft of the rotary tiller, there is welded and fixed a knife magazine that matches the root of the handle of the rotary tiller and paddy field burying grass. There are fixing screws on the side of the knife magazine. Wire fixed.

The beneficial effect is that the paddy field straw burying rotary cultivator can complete operations such as paddy field straw burying, rotary plowing and soil preparation, and the like at one time after the paddy field grass burying knife is installed. After the rotary tiller is replaced, the rotary tillage and soil breaking operations can be completed at one time, so that one machine can be used for two purposes. It is beneficial to realize straw returning to the field, increase soil organic matter, enhance soil fertility, increase crop yield by 5%-10%, and avoid environmental pollution caused by straw burning.

Detailed ways

In the figure, the machine has a plate-shaped left and right support arm 10, a coulter transmission box 1, a left side plate 8, a chain box assembly 9 and a fender 4 combined and welded together to form a rectangular frame. The coulter transmission box 1 is installed above the middle of the frame, and the joystick 2 protrudes from one side of the coulter transmission box 1 to the rear. The coulter transmission box 1 is connected with the drive shaft of the tractor to input power. It is installed and rotated synchronously with the sprocket of the chain box assembly 9 on the right, and is connected with the drive wheel of the rotary tiller 6 on the cutter shaft and the paddy field burying knife 7 through the chain, so as to realize straw burial, rotary tillage and broken soil operations, and is rotated The cultivated land and the soil clods thrown back are dragged by the fender 4, the cover 3 and the drag plate 5 to make the land level, and the function of leveling the land can be realized. The rotary tiller 6 and the paddy field burying knife 7 are fixed symmetrically On the rotary tillage axis, the included angle between the two welds of the left and right paddy field burying knives is in the range of 65° to 75°. On the outer diameter of the rotary tiller shaft, there is welded and fixed a knife storehouse matching the roots of the rotary tiller knife 6 and the paddy field burying grass knife 7 handles, and the side of the knife storehouse is provided with fixing screws, and the knife handle is inserted into the knife storehouse during installation. fixed by wire.

In the figure, the machine is used in conjunction with various tractors with more than 15 horsepower. It is based on the original rotary cultivator and can be used after replacing the paddy field burying knife 7.
