Flexible seed sowing device

Abstract

The invention belongs to the technical field of agricultural machines and relates to a flexible seed sowing device. A seed filling chamber is disposed below a seed hopper. The seed hopper is separated from the seed filling chamber by an inclined separator plate. Seeds in the seed hopper flow into the seed filling chamber through a seed channel between the separator plate and the anterior wall of the seed hopper. To increase fluidity for seed filling, a stirrer is disposed inside the seed filling chamber. Stirring teeth on the stirrer are spirally arranged in pairs. A flexible synchronous beltbelow the seed filling chamber is inclined and arranged parallel to the rotating shaft of the stirrer. With slots on the outer surface of the flexible synchronous belt are skewed slots. When the seedsowing device is working, the movement track of the ends of the stirring teeth is consistent with the direction of the long side of the with slots, thus making the shape arrangement of the seeds consistent when the seeds flow, making the seed flowing track along the direction of the long side of the with slots and increasing the seed filling effect. After seed filling, a seed clearing brush is used to remove superfluous seeds, which are conveyed under the protection of a seed protecting device to a seed outlet for seed charge. The invention can be used to solve mechanical sowing problems thatthe fluidity is poor and Gramineae herbage seeds are not easy to sow, and is suitable for mechanical sowing of Gramineae or leguminosae herbage.

Description

technical field [0001] The invention belongs to the field of agricultural machinery, in particular to a flexible seed metering device. Background technique [0002] In the current common seed metering devices, a certain volume of cavity is usually used to control the filling of single or multiple seeds and then realize seed metering. The seed flow formed by the weight of the seed itself is completed, which requires that the friction and extrusion force between the seeds should not be too large to affect the seed flow. In addition, the filling cavity should also meet the requirements of single or multiple seed filling. When the traditional mechanical seed metering device sows light weight, long and narrow gramineous grass seeds with awns, the above two aspects will encounter difficulties. It is not easy to flow stably and fill the seeds, and the long and narrow shape of the seeds brings difficulties to the design of the filling chamber. In terms of agronomic requirements, g...

Problems solved by technology

[0003] The object of the present invention provides a kind of flexible seed metering device for solving the problem of mechanized sowing of seeds such as poor fluidity and difficult sowing grasses described in the background technology, and it is characterized in that, the seed box 1 is a cuboid shell, and the seed chamber 3 is fixedly connected with the lower part of the seed box 1, and the partition plate 2 is fixedly connected with the side wall and the rear wall of the seed box 1 at an angle θ from the horizontal plane in the seed box 1, and the partition plate 2 separates the seed box 1 from the seed filling chamber. Open, the interval between the partition plate 2 and the front wall of the seed box 1 is the seed passage 4, the space in the seed filling chamber 3 is an inverted trapezoid that gradually shrinks, the front wall of the seed filling chamber 3 is perpendicular to the partition plate 2, and the seed filling The bottom of the chamber 3 is a rectangular outlet, the rectangular outlet at the bottom of the seed filling chamber 3 is parallel to the partition 2, and the two side plates 5 are parallel and vertically connected to the lower part of the outer sides of the two side walls of the shell of the seed filling chamber 3, respectively. The rear cover 6 is fixedly connected to the rear edge and the upper part of the lower edge of the two side plates 5, the seed outlet 7 on the rear cover 6 is downward, and the rear cover 6 closes the rear parts of the two side plates 5;
