Further, in order to reduce the friction extrusion degree in the soybean grain taking process, and simultaneously improve the grain dispersion degree of the soybean during the subsequent sowing, and improve the sowing density and the emergence rate, as shown in fig. 6, 7 and 10, the inner side of the grain taking pipe 3 is provided with an air cavity, the inner side of the grain taking groove 31 is provided with an air outlet hole 33 communicated with the air cavity, the inner side of the air outlet hole 33 is filled with filter cotton, an elastic air bag 44 is installed in a middle cavity of the accommodating barrel 30, the bottom of the air bag 44 is communicated with the inner air cavity of the grain taking pipe 3 through a hose, the outer wall of the grain taking pipe 3 is fixedly provided with a scraping plate 34, and the outer wall of the scraping plate 34 is in sliding abutting contact with the side wall of the air bag 44 to form extrusion.
During operation, in the process that the particle taking pipe 3 downwards enters the quantitative cylinder 4, the scraper 34 is driven to synchronously downwards move, at this time, the scraper 34 is attached to the outer wall of the air bag 44 to slide, and forms an upward-downward extrusion effect on the air bag 44, so that air inside the air bag 44 overflows outwards, at this time, overflowed air reaches the air cavity inside the particle taking pipe 3 through the hose and overflows from the position of the air outlet hole 33, through the blowing effect of the air flow, the gap between soybean seeds is enlarged, and the soybean seeds are upwards lifted under the blowing effect of the air flow, so that the resistance of the particle taking pipe 3 entering the inner side of the soybean seeds is reduced, the mutual friction extrusion degree between the soybean seeds is synchronously reduced, the falling-off amount of the soybean seed outer coating is reduced, the stress resistance of the soybean seed outer coating is improved, when the particle taking pipe 3 is outwards pulled by an operator, at this time, the air is reversely sucked from the position of the air outlet hole 33, the smoothness of the soybean seeds entering the particle taking groove 31 is improved, the stability is improved, the whole particle taking process is stopped is improved, and the particle taking accuracy is controlled.
Further, in order to avoid the decrease of stress resistance caused by falling of the soybean coating due to friction extrusion in the process of taking the grains, as shown in fig. 5, 6 and 8, the upper end of the plastic tube 21 is communicated with the storage box 2 through a flexible corrugated tube, the middle part of the plastic tube 21 is obliquely directed to the quantitative cylinder 4, the bottom of the plastic tube 21 is communicated with the middle part of the quantitative cylinder 4, the side wall and the bottom of the middle part of the quantitative cylinder 4 are provided with ventilation holes 45, and the diameter of the ventilation holes 45 is smaller than that of the soybean.
When the soybean seed sowing device works, the ventilation holes 45 in the middle and bottom of the quantitative cylinder 4 are uniformly formed, the falling-off medicament coating can naturally fall conveniently, in the process of taking grains, along with the discharge of air flow from the position of the air outlet hole 33, the falling-off coating can be synchronously blown to the outer side of the quantitative cylinder 4 by overflowed air flow, the coating falls into the sowing acupoint of the soybean seed under the action of gravity of the overflowed rear neck and is contacted and mixed with soil, wide-area pesticide coating of a soybean sowing area is realized, the utilization degree of the medicament is improved, in addition, after the grain taking is finished, the grain taking pipe 3 is reversely pulled by a worker, so that the turning rod 51 reversely deflects, after the turning rod 51 reversely deflects, the grain taking pipe 3 is positioned at the position right above the sowing acupoint, at the moment, the grain taking pipe 3 is pushed downwards again, the grain taking pipe 3 is exposed out of the accommodating cylinder 30, at the moment, the air flow is again subjected to the downward extrusion action at the position of the air outlet hole 33, the air flow is blown to enable the soybean in the grain taking groove 31 to fall down, sowing is finished, and the soybean seeds are uniformly dispersed by the air flow, the soybean seeds are uniformly spread and the nutrient is uniformly sprayed, the average, and the nutrient density is also can be absorbed at the outer side of the sowing position, and the sowing position is reasonable, and the sowing density is reasonable.
The foregoing has shown and described the basic principles, main features and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the foregoing examples, and that the foregoing description and description are merely illustrative of the principles of this invention, and various changes and modifications may be made without departing from the spirit and scope of the invention, which is defined in the appended claims. The scope of the invention is defined by the appended claims and equivalents thereof.
