Description
Technical Field
The invention relates to the technical field of peanut harvesters.
Background
Such apparatuses have not been found yet, as yet, retrieved. Peanuts are widely planted in China, and a peanut harvester plays an important role in the peanut harvesting process. The peanut harvester separates the peanut from the peanut seedling in the working process, and the peanut separated from the peanut seedling inevitably carries peanut stems, so that the peanut harvesting quality is affected, and in order to further improve the quality of the harvested peanut, the peanut stems need to be further picked from the peanut seedling.
Disclosure of Invention
The invention aims to solve the technical problem of providing a peanut stem picking device for a peanut harvester, which has the characteristics of low energy consumption, simple and practical structure, high working reliability and the like. The fruit stalks of the harvested peanuts can be picked off, so that the quality of the harvested peanuts is further improved.
In order to solve the technical problems, the invention adopts the following technical scheme:
peanut stem picking device for peanut harvester, its characterized in that: the peanut stem picking mechanism comprises a peanut stem receiving guide groove, wherein the peanut stem receiving guide groove is a groove body mainly composed of a left guide groove wall, a right guide groove wall and a guide groove bottom wall which is inclined downwards from back to front, and the guide groove bottom wall of the peanut stem receiving guide groove is provided with a peanut stem picking mechanism: comprises a fruit handle bracket and at least one fruit handle tray, wherein the fruit handle tray comprises a plurality of fruit handle saws and fruit handle saw fixing shafts, the fruit handle saws are round saw blades, the fruit handle saws are fixed on the fruit handle saw fixing shafts at intervals, a row of fruit handle saw slots are arranged at intervals on the bottom wall of the guide slot of the peanut receiving guide slot, the front and back directions of the row of fruit handle saw slots are parallel, the width of each fruit handle saw slot is matched with the thickness of the fruit handle saw, the interval between the fruit handle saw slots is matched with the interval between the fruit handle saws of the fruit handle tray, the fruit handle saw fixing shafts are transversely arranged below the peanut receiving guide slot, the left end and the right end of the fruit handle saw fixing shafts are respectively supported on the left side and the right side of the machine, one end of each fruit handle saw fixing shaft is fixed with a handle saw transmission part, the upper part of each fruit picking handle saw of each fruit picking handle disc is embedded into each fruit picking handle saw slot hole at a corresponding position, the fruit picking handle saw slot hole part corresponding to the saw tooth at the front end of each fruit picking handle saw forms a fruit handle supporting slot, the saw tooth of each fruit picking handle saw inclines towards the rotating direction, so that the fruit handle at the fruit handle supporting slot can not slip when being subjected to the downward cutting force of the saw tooth of the fruit picking handle saw, the engine power output shaft of the peanut harvester drives the handle saw transmission part arranged on the fruit picking handle saw fixing shaft to rotate through the transmission device, so as to drive the fruit picking handle saw of each fruit picking handle disc to rotate forwards from back to back in the slot cavity of the peanut receiving guide slot, and the saw tooth of each fruit picking handle saw cuts off the fruit handle at the position under the support of the slot edge of the corresponding fruit handle supporting slot.
The invention is further improved in that:
the bottom wall of the guiding groove of the peanut bearing guiding groove consists of metal strips which are arranged at intervals in the front-back direction, and gaps among the metal strips form saw slots of the peanut picking handle.
The two fruit picking handle discs are arranged in parallel front and back; the spacing distance between the fruit picking handle saw and the fruit picking handle saw fixing shaft is 4 cm-6 cm.
The beneficial effects of adopting above-mentioned technical scheme to produce lie in:
The bottom wall of the guide groove of the peanut receiving guide groove is inclined downwards from back to front, the peanut falling into the peanut receiving guide groove slides forwards, and in the sliding process, the transmission device drives the handle saw transmission part arranged on the handle saw fixing shaft to rotate so as to drive the handle saw of each handle tray to rotate forwards from back to back in the groove cavity of the peanut receiving guide groove, so that the saw teeth of each handle saw cut off the fruit handle positioned at the position under the support of the groove edge of the corresponding handle supporting groove; because the fruit picking handle saw is a circular saw blade, the saw tooth spacing is smaller than the particle size of the peanuts, the peanut can not be damaged, and because the saw teeth of each fruit picking handle saw incline to the rotating direction, the fruit handle at the fruit handle supporting groove can not slip when being subjected to the downward shearing force of the saw teeth of the fruit picking handle saw, thereby completing the picking work of the peanut handle, the peanut bearing guide groove is in a vibration state under the drive of the bidirectional balance vibration mechanism, so that the peanuts can conveniently turn back and forth at the bottom wall of the guide groove, the probability that each peanut passes through the stem supporting groove is increased, the picking performance of the peanut stem is improved, and the picking rate of the peanut stem is improved by adjusting the distance between the stem picking saw.
