A small creeping peanut digging harvester for mulching planting

Abstract

The invention relates to a peanut harvesting machine, which is a small creeping peanut digging and harvesting machine for film-covered planting. A digging shovel (2) with a pointed front is arranged horizontally at the lower end of the front end of the frame, and the excavating shovel (2) ) to the rear cross bar configuration of the rectangular frame from the lower front to the rear upper toothed conveyor chain (3); respectively configure a guide plate (4) at the both sides of the toothed conveyor chain (3); A pair of toothed rotary cylindrical cylinders (7) are arranged between the guide plates (4): the toothed rotary cylindrical cylinders (7) are a plurality of rows of metal ring gears perpendicular to the axis protruding from the outer surface of the cylindrical cylinder. It is a triangular tooth plate protruding along the circumference, and the outer surface of the gear ring is covered with rubber coating; two left and right turning plates (8) are arranged behind the toothed rotary cylindrical cylinder (7), and the upper surface of the turning plate (8) Extending opposite to each other and the upper surface goes downwards through a rotating shape and smoothly transitions to the upper surface facing downwards. The invention overcomes the drawbacks of the prior art in domestic peanut fields covered with agricultural film that are easy to be entangled, clamped rods, and clamped fruits, and can give full play to the advantages of large-scale mechanized harvesting.

Description

Technical field [0001] The invention relates to a peanut harvesting mechanical equipment, in particular to a peanut harvesting mechanical structure covered with a film. Background technique [0002] In foreign countries, especially in the United States, most of the large creeping peanut varieties are planted with side branches longer than 1.5-2.0 meters, and the planting row width is more than 1.0 meters. They are planted in a single row. When peanuts are harvested, the peanut digging harvester first completes the peanut digging, conveying, soil clearing, and overturning operations at one time. After the peanuts are dried to a certain moisture content, the peanut picking combine harvester completes the picking and fruit picking operations. Because the American peanut varieties are creeping, it is very easy to tip the peanut vines upside down through the specially designed tipping mechanism during excavation and harvesting, which is conducive to the rapid drying of peanuts, create...

AI Technical Summary

Problems solved by technology

However, due to the use of plastic film during planting in our country, when the American peanut digging harvester is used intact, it is very easy to wind the agricultural film and peanut seedlings between the multi-row polygonal rotary disks on the overturning mechanism, and the peanut pods are also very easy to entangle. Stuck between the polygonal rotary disc and the guide rod, resulting in the loss of peanuts, and as the agricultural film and seedlings continue to wind and accumulate, the relative position between the polygonal rotary disc and the guide rod will change, and the peanut seedlings will The trajectory of the movement will change accordingly, and the overturning device may fail, and the overturning effect will not be achieved.

Therefore, the promotion and use of American peanut digging and harvesting machines in China is hindered
