Embodiment Construction

[0041] The present invention will be further described below in conjunction with the accompanying drawings, wherein the end with the electric push rod 8 is the right side, and the side with the motor 5 is the left side, so as to establish a left and right direction reference for description, with a seed cleaning door One end of 12 is the rear end, and the opposite end is the front end:

[0042] seed meter, such as Figure 1-3 As shown in the figure, it includes a shell 1. The shell 1 can be welded by a plurality of side plates 11 to form a structure in which the surrounding is connected and the upper and lower ends are connected. A special chassis is added at the bottom of the shell 1, and the rear end of the chassis is provided with There is a connecting shaft, and the connecting shaft is used for docking with the opener of the seeder. A hinge 10 is arranged above the rear end of the housing 1, and a through slot is opened below the hinge 10. The through slot is communicated ...

Abstract

The invention relates to a seed metering device. The seed metering device comprises a shell, a seed box, a seed metering wheel and a control system; a seed cleaning door is arranged at one end of theshell and is used for discharging seeds; the seed box is of an up-and-down through structure, and the bottom of the seed box is provided with a slot and an inserting plate so as to be communicated with the inside of the shell; the seed metering wheel is arranged at the bottom of the shell and is used for metering and cleaning the seeds in the shell; and the control system is used for operating andcontrolling a motor, an electric push rod and the like of the seed metering device. The seed metering device is provided with the seed box, the shell and the seed metering wheel from top to bottom, is simple to operate, quick and convenient to adjust, accurate in seeding positioning, high in efficiency, low in labor intensity, low in danger coefficient and capable of guaranteeing farming time. The seeds are cleaned through the seed cleaning door, machine lifting for seed changing is not needed, and redundant seeds in the seed metering device are automatically cleaned. The row spacing is set through a touch screen, and the spacing of the seeds during sowing is flexibly adjusted.

Description

technical field [0001] The invention belongs to the technical field of mechanized seed metering, in particular to a seed metering device. Background technique [0002] As a mechanized agricultural production equipment, seed metering devices are increasingly used in different field farming methods, such as large-scale field planting production and small-scale scientific research sowing. In the process of large-scale production and sowing, because of its features of automation and high efficiency, it requires less manpower than manual sowing, and can complete the sowing goal faster, and has been widely used. However, there are many related technical difficulties in the actual use of the seed metering device for scientific research seeding in the community, which is difficult to meet the actual needs of scientific research and sowing in the community, thus restricting the application effect. [0003] It is difficult for the operator to grasp the exact position of the sowing se...
