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
The present invention relates to agricultural machinery, especially relate to the directed seeding apparatus of a kind of arc line type guide plate super hybridization rice.
Background technology
The super hybridization rice seedling is compared with traditional raising rice seedlings, and hole plate seedling raising is a precise sowing by the defective ejaculation amount sowing lifting in original 2-5 grain/cave, i.e. 2 ± 1/ caves; Blanket shape seedling (not having border, seedling cave accurately between the Miao Yumiao) is changed into 2 ± 1/seedling taking area by original 3-5 grain/seedling taking area.See that from interrelated data research the method to the directed sowing of super hybridization rice is to utilize the long villous in seed rice surface at present, the direction of motion is different and frictional force that cause is different, realizes the purpose of orientation.But because the super hybridization rice kind is more, each seed all has the characteristic of himself, and also has individual difference between the similar seed, therefore can not obtain satisfied orientation ratio in actual use kind.
Summary of the invention
The object of the present invention is to provide the directed seeding apparatus of a kind of arc line type guide plate super hybridization rice, the seed rice that drops in the seedling dish is arranged by same direction, simple in structure, can adapt to the sowing requirement of all kinds of super hybridization rice seeds.
In order to achieve the above object, the technical scheme of the present invention's employing comprises:
The present invention includes kind of a case, plate vibration plate, many arc-shaped guide plates, V-arrangement parabola plate, first frame, second frame and vibration exciter.Plate vibration plate and horizontal plane tilt to be installed on first frame; The plate vibration plate with can do reciprocating linear motion after vibration exciter is connected; Plant case and be installed in the high-end of plate vibration plate; Many arc-shaped guide plate is vertically mounted on the low end face of plate vibration plate; The angle of the tangential direction of many arc-shaped guide plates and plate vibration plate low side horizontal edge becomes greatly to low side from high-end gradually, and the tangential direction of the end of many arc-shaped guide plates becomes 90o with the low side horizontal edge of plate vibration plate, and the V-arrangement parabola plate with identical number of many arc-shaped guide plates is installed in many arc-shaped guide plate lower ends; And every arc-shaped guide plate aligns with the bottom land of separately V-arrangement parabola plate successively each other, and V-arrangement parabola plate is installed on second frame.
The V-shaped groove angle of described V-arrangement parabola plate is 40o～60o.Described plate vibration plate (2) is 20o～30o with the horizontal plane angle of inclination.
The beneficial effect that the present invention has is:
The present invention be directed to super hybridization rice precisely sows and require to propose.Plate vibration plate and horizontal plane have an inclination angle; Arc-shaped guide plate is vertically mounted on the plate vibration plate; Fall seed rice on the plate vibration plate under the effect of inertia force (being provided by vibration force), frictional force, gravity etc., seed rice moves along the arc-shaped guide plate with friction plate on the plate vibration plate.Because seed rice surface fine hair has directionality, and is therefore in motion process, less along embryo's direction kinetic friction force, otherwise then bigger.The seed rice that moves along arc-shaped guide plate; Because the change of angle, the moment of couple that frictional force that seed rice receives and inertia force form reduces gradually, and the frictional resistance moment of seed rice on the plate vibration plate is constant; Therefore as long as make the moment of couple that rigidly connects seed rice frictional force and inertia force formation of (embryo is in the back when moving) when driving in the wrong direction of touching guide plate greater than the frictional resistance moment of seed rice on the plate vibration plate; The seed that then moves along arc-shaped guide plate has experienced under two kinds of situation (embryo is preceding, and the embryo is in the back) and has all turned in motion process, to having only the seed rice embryo at the back, to turn to; To keeping the constant process of ordering effect, realize the purpose that aligns.Improved the adaptability of seed greatly.Seed rice velocity attitude and horizontal direction through the guide plate ordering have an angle, just the angle between plate vibration plate and the horizontal plane.Seed rice is through the parabola plate, and the velocity attitude of seed rice changes horizontal direction into, and is consistent with seedling dish moving direction, and seed can not produce spring after touching soil, arranges in order, reaches the position of emerging and evenly distributes.
