Description

MULTIFUNCTIONAL STRAW CHECKERBOARD PAVING VEHICLE

LU504000

TECHNICAL FIELD

The present disclosure belongs to the technical field of agricultural machinery, and particularly relates to a multifunctional straw checkerboard paving vehicle.

BACKGROUND

As a desert control way for wind protection, sand fixation, and water conservation, the netted straw checkerboards function as inanimate mini-protective belts for a desert to be interlocked into a whole. In order to control desert with the straw checkerboards, the dry straw is required to be inserted into soil, so as to hinder sand from moving, reduce blowing sand and slow down the movement of sand. Conventionally, the straw checkerboard is manually inserted into soil and paved. À vast number of workers are needed for such manual work, resulting in a high labor intensity, a low efficiency, and a high overall cost. Moreover, the desert is generally wide in area, resulting in a long paving time. Lasting exposure to the windy and sunny desert will also affects the workers’ physical health upon inhalation of plenty of sand. Although an automatic straw checkerboard paving machine has been invented, it is likely to slip and work inefficiently because of inferior drivability in the desert and an extremely high slippage rate. In the case of steep slopes and sand pits, it gets stuck and hardly moves. The machine works only after straw is pre-made into straw curtains, which is complicated. Without a ditching function, the straw is rolled with tremendous pressure. In the presence of hard soil, the depth of the rolled straw curtain will be insufficient. Without a sand backfill device and a sand compacting device, the rolled straw checkerboard will not solid enough, and accordingly, the straw checkerboard will be low-quality. With a complex structure, a large number of transmission shaft devices will be utilized, resulting in a heavy maintenance workload and a high maintenance cost.

With reference to FIGS. 1-7, the present disclosure provides a multifunctional straw checkerboard paving vehicle. The vehicle includes: a vehicle body 10, a storage battery 20, a straw storage bin 30, a plough blade 40, a straw rolling wheel 50, a sand backfill device 60, and a sand compacting device 70. The storage battery 20 is mounted on the vehicle body 10. The plough blade 40, the straw rolling wheel 50, the sand backfill device 60, and the sand compacting device 70 are sequentially mounted at a bottom end of the vehicle body 10. The straw storage bin 30 is mounted at a top of the vehicle body 10. An opening 31 is defined at a bottom of the straw storage bin 30, and the opening 31 is used for dropping a straw into a ditch 504000 formed when the plough blade 40 advances. The plough blade 40 is in an inverted triangle shape, and the plough blade 40 is driven to advance for ditching when the vehicle is in operation. The straw rolling wheel 50 is in a circular discus shape, with a bearing structure mounted at a center of a circle, and the straw rolling wheel 50 is rotatable. Two circular wheels with fixed angles in the sand backfill device 60 are in a diverged shape from back to front, to better backfill shifted sand to two sides of the straw, so that the straw is more stable. The sand compacting device 70 is in a semi-solid flat rolling wheel shape, to make contact with the ground, so as to compact the backfilled sand when the vehicle advances.

When the multifunctional straw checkerboard paving vehicle is in operation, firstly, the plough blade 40 ditches the sand, and the straw just drops into a ditch through the opening 31 in the straw storage bin 30. The straw rolling wheel 50 rolls to compact the straw dropped into the ditch. Then the sand backfill device 60 returns the sand to backfill the sand to the two sides of the straw. Finally, the sand compacting device 70 compacts the backfilled sand.

The multifunctional straw checkerboard paving vehicle further includes a straw shifting device. The straw shifting device includes a first electric motor 81, a first straw shifting roller, a second straw shifting roller, a first gear 84, a second gear 85, and a transmission belt 86. The first electric motor 81 is mounted on the vehicle body 10. The first straw shifting roller and the second straw shifting roller are mounted in the straw storage bin 30 through bearings.
