Problems solved by technology

However, since there are many types of super rice, each seed has its own characteristics, and there are individual differences among seeds of the same kind, so the satisfactory orientation rate cannot be obtained in the actual use process.

Embodiment Construction

[0014] The present invention will be further described below in conjunction with accompanying drawings and implementation.

[0015] Such as figure 1 , figure 2 Shown, the present invention comprises seed box 1, flat vibrating plate 2, a plurality of arc guide plates 3, V-shaped parabolic plate 5, first frame 6, second frame 7 and vibration exciter 8; Flat vibrating plate 2 is installed on the first frame 6 inclined to the horizontal plane, and the flat vibration plate 2 can perform reciprocating linear motion after being connected with the vibration exciter 8. The seed box 1 is installed on the high end of the flat vibration plate 2, and multiple arc-shaped guide plates 3 Installed on the low end surface of the flat vibrating plate 2, the angle between the tangential direction of the multiple arc-shaped guide plates 3 and the horizontal side of the low end of the flat vibrating plate 2 gradually increases from the high end to the low end, and the angle between the multiple a...

Abstract

The invention discloses an arc guide plate super rice oriented sowing device. In the device, a vibrating plate is obliquely arranged on a frame, and is connected with a vibration exciter to make reciprocating linear motion; a seed case is arranged at the higher end of the vibrating plate, and a plurality of arc guide plates are vertically arranged on a lower end face of the vibrating plate; included angles between the tangent directions of the plurality of arc guide plates and a lower transverse edge of the vibrating plate become larger gradually from top to bottom, until the tangent direction of an arc guide plate forms an angle of 90 degrees with the lower transverse edge; V-shaped parabolic plates in a number the same as that of the plurality of arc guide plates are arranged at the lower ends of the plurality of the arc guide plates; each arc guide plate is aligned with the groove bottom of a respective V-shaped parabolic plate; and the V-shaped parabolic plates are arranged on another frame. Rice seeds slide along the arc guide plates on the vibrating plate and change the direction to ensure that rice seed embryos are arranged along the guide plates in the same direction and fed into the parabolic plates and leave the parabolic plates at a horizontal speed which is consistent with the horizontal forwarding speed of a tray, so the rice seed embryos are protected against bounce after the rice seed embryos are contacted with earth, and are arranged sequentially to achieve uniform distribution of emergence positions.

Description

technical field [0001] The invention relates to agricultural machinery, in particular to an arc-shaped guide plate super rice directional sowing device. Background technique [0002] Compared with traditional rice seedling raising, super rice seedling raising has been upgraded from the original 2-5 grains / hole precision seeding to precision seeding, that is, 2±1 / hole; Seedling hole boundary) changed from 3-5 grains / seedling area to 2±1 grains / seedling area. From relevant data research, the current method for directional sowing of super rice is to use the surface of rice seeds to have fluff, and the frictional force caused by different moving directions is different to realize the purpose of orientation. However, because there are many kinds of super rice, each seed has its own characteristics, and there are individual differences among the same seeds, so the satisfactory orientation rate cannot be obtained in the actual use process. Contents of the invention [0003] The...
