Problems solved by technology

However, the seed filling method of the vertical seed tray with this type of structure only uses the lateral pressure generated by the interaction between the seeds to fill the seed grains into the seed filling holes, and cannot use the gravity of the seeds to assist in completing the seed filling operation. As a result, the seed filling effect of the traditional vertical disc seed meter is not ideal under the condition of high-speed rotation, and the seed filling rate still needs to be improved

Embodiment Construction

[0010] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. A vertical seeding disk that can be filled with gravity. The seeding disk 2 is in the shape of a basin as a whole. 2 The side walls are evenly distributed along the circumferential direction with seed-filling holes 3, and a pot-shaped seed protection plate 1 matching it is arranged in the basin cavity of the basin-shaped seed-discharging tray 2, and the side wall of the pot-shaped seed protection plate 1 will be Part of the seed-filled hole 3 on the side wall of the pot-shaped seeding tray 2 is shielded and covered.

[0011] During operation, in the seed filling area on the lower side of the casing of the vertical disc seed metering device, the seeds are filled into the seed filling type of the rotating seed metering disc 2 under the joint action of the side pressure generated between the seeds and its own gravity. In the hole 3, under the common protec...

Abstract

The invention provides a vertical seed-metering disc capable of utilizing gravities for seed filling, belonging to agricultural machinery. The vertical seed-metering disc is characterized in that a seed-metering plate is wholly basin-shaped; the inner surface of the side wall of the basin-shaped seed-metering plate is wholly cone-shaped; seed filling holes are uniformly distributed on the side wall of the basin-shaped seed-metering plate along the peripheral direction; a basin-shaped seed protection plate matched with the seed-metering plate is arranged in a basin cavity of the basin-shaped seed-metering plate; and the side wall of the basin-shaped seed protection plate shields and covers part of the seed filling holes on the side wall of the basin-shaped seed-metering plate. The vertical seed-metering disc has the following beneficial effects: the disc completes seed filling by utilizing lateral pressures generated through mutual extrusion of the seeds and the gravities of the seeds; the seed filling rate is improved; and the disc has the characteristics of novel, reasonable and simple structure, low manufacture cost, good seed-metering quality and reliability in use.

Description

technical field [0001] The invention belongs to agricultural machinery, and mainly relates to a vertical disc seed metering device. Background technique [0002] The vertical seed metering disc in the traditional vertical disc seed metering device adopts a circular plate-shaped disc body, and the structural design of seed-filling holes is uniformly arranged at the peripheral edge of the circular plate-shaped disc body. Because of its small axial size, simple structure, convenient transmission, accurate seeding, small variation in plant-to-plant spacing, and low seed damage rate, it has been widely used in agricultural production. However, the seed filling method of the vertical seed tray with this type of structure only uses the lateral pressure generated by the interaction between the seeds to fill the seed grains into the seed filling holes, and cannot use the gravity of the seeds to assist in completing the seed filling operation. As a result, the seed filling effect of...
