Description

Rolling screen type oily bean harvester cleaning mechanism

technical field

The utility model belongs to agricultural machinery and mainly relates to a cleaning operation mechanism on a rolling screen type oily bean harvesting machine.

Background technique

In order to adapt to and meet the needs of the mechanized harvesting of oil bean bean harvesting operations that continue to expand the planting area, the rolling screen bean bean harvesting machine has been developed. , and there is no wind blowing off the sundries on the single-layer screen. In actual practice, it is found that the straw transported from the rotary conveyor belt assembly of the harvesting machine to the single-layer screen is wrapped with more particles than The large and good-quality oily bean can not be separated and recycled, and it is discharged out of the machine with the straw, resulting in the loss of the oily bean, and the straw is not discharged smoothly or even blocked.

SUMMARY OF THE INVENTION

The purpose of this utility model is to aim at the problems existing in the above-mentioned prior art, and to study and design a new structure of the rolling screen type oily bean harvester cleaning mechanism in combination with the actual needs of the oily bean mechanical harvesting operation. The upper screen assembly is installed on the upper part of the type single-layer screen, and the technical scheme of removing the straw located on the upper screen assembly and separating and recovering the oily bean seeds can be achieved by cooperating with the blower in sections, so as to improve the recovery rate and cleaning rate of the oily bean and ensure the The purpose of smooth operation of the machine and reducing the occurrence of failures.

The basic design of the utility model is as follows: the cleaning mechanism of the rolling screen type oily bean harvester includes a blower, a vibrating lower screen assembly and a rotary conveyor belt assembly, and a main air supply pipe is installed on the air outlet of the blower, The middle part and the rear end part of the main air transmission pipeline are respectively installed with a front branch pipe for air transmission and a rear branch pipe for air transmission; an upper screen assembly is installed on the upper end of the vibrating lower screen assembly, and the upper screen assembly is installed The vertical wall surface of the front side is provided with an upper screen miscellaneous discharge port, and the miscellaneous discharge baffle is installed on the front end of the upper screen assembly in a laterally inclined manner, and is matched with the top screen miscellaneous discharge port; The air end is installed on the vertical side wall of the upper screen assembly, and the air is supplied horizontally; the exhaust end of the branch pipe after the air supply is installed on the rear end of the upper screen assembly, and the air is supplied longitudinally; The material discharge end of the rotary conveyor belt assembly is communicated with the rear side feeding end of the upper screen assembly.

The utility model can efficiently separate and recycle the oily bean stalks entrained in the residual straw, and discharge the residual straw out of the machine smoothly. High efficiency, reliable use and less failure.

FIG. 2 is a partial view from the direction A of FIG. 1 .

Description of the part number in the picture:

1. Hair dryer, 2. Main air pipeline, 3. Front branch pipeline, 4. Rear branch pipeline, 5. Vibrating lower screen assembly, 6. Upper screen assembly, 7. Discharge baffle, 8. Rotary conveyor belt assembly, 9. Upper sieve discharge port.

Detailed ways

The embodiments of the present utility model will be described in detail below with reference to the accompanying drawings. A rolling screen type oily bean harvester cleaning mechanism includes a blower 1, a vibrating lower screen assembly 5 and a rotary conveyor belt assembly 8, and a main air supply pipe 2 is installed on the air outlet of the blower 1, and the The middle part and the rear end part of the main air transmission pipe 2 are respectively installed with the front branch pipe 3 and the rear branch pipe 4; On the vertical wall surface of the front side of the upper screen assembly 6, an upper screen miscellaneous discharge port 9 is provided, and the miscellaneous discharge baffle plate 7 is installed on the front end of the upper screen assembly 6 in a laterally inclined manner, and cooperates with the upper screen miscellaneous discharge port 9; The exhaust end of the front branch pipe 3 for air transmission is installed on the vertical side wall of the upper screen assembly 6 to supply air horizontally; the exhaust end of the air transmission rear branch pipe 4 is installed on the upper screen assembly 6 On the rear end of the screen, the air is longitudinally supplied; the material discharge end of the rotary conveyor belt assembly 8 is communicated with the rear side feeding end of the upper screen assembly 6.

During operation, the material discharge end of the rotary conveyor belt assembly 8 sends the stalks entrained with part of the oily bean to the upper screen assembly 6 from the rear feeding end of the upper screen assembly 6. Driven by the vibrating lower sieve assembly 5, the upper sieve assembly 6 vibrates at the same time to shake and separate the sesame beans entrained in the straw from the straw, and fall onto the vibrating lower sieve assembly 5; at the same time, the blower 1 The wind blows the straw longitudinally from the rear of the upper screen assembly 6 to the front through the main wind pipe 2 and the rear branch pipe 4, and the other wind blows through the main wind pipe 2 and the front branch pipe 3. The straw located at the front side of the upper screen assembly 6 is blown laterally to the outside of the machine from the upper screen trash discharge port 9 under the cooperation of the trash discharge baffle 7 to complete the recovery of the oily bean from the straw.
