Single profiling device of precision seeder

Abstract

The invention belongs to the field of agricultural machinery, and relates to a single profiling device of a precision seeder. The single profiling device comprises a front frame seaming, an upper rodseaming, a lower rod and a support rod seaming, one end of the upper rod seaming is hinged with one end of the front frame seaming, and the other end of the upper rod seaming is connected with a seedmetering device shell (namely a seeder working part) of the precision seeder; the other end of the front frame seaming is hinged to one end of the supporting rod seaming and one end of the lower rod at the same hinge point, the other end of the lower rod is hinged to a seed metering device shell of the precision seeder, the other end of the supporting rod seaming is in sliding connection with theupper rod seaming, and a suspension frame cross beam of the suspension frame is connected with the front frame seaming; and the front frame seaming, the upper rod seaming, the lower rod and the seed-metering device shell form a parallel four-bar mechanism.

Description

technical field [0001] The invention belongs to the field of agricultural machinery, and in particular relates to a single profiling device for precision seeding machinery. Background technique [0002] When the seeder performs multi-row operations, when the working parts of each row and the suspension frame (connected to the tractor parts) are connected separately, the working parts and their connecting parts are called a single group. and tow The suspension frame connected to the pulling machine can hang multiple single groups or a single group, and the number of groups can be determined according to the specific needs of farmers. When the seeder is working, a single group moves up and down with the undulation of the ground, which is called profiling. The parallel four-bar linkage mechanism is a commonly used profiling mechanism on the seeder to ensure that the opener's entry angle remains unchanged and the seeder's sowing depth is consistent. During the working process o...

Problems solved by technology

During the working process of multiple groups of single seeders, when the sowing reaches the last stage or the sowing width is not the entire width of the machine due to irregularities in the field, it is required to sow part of the single group, and the remaining part of the single group stops working. Currently, the common solution The method is: 1. There is an insert plate between the seed box and the seed metering device. The disadvantage is that the single group that stops working needs to clean out the seeds in the seed metering device. The operation is complicated. 2. Use the neutral gear to cut off the transmission. The disadvantage is that the openers and the compaction profiling wheels continue to work, causing machine wear and repeated compaction of the soil by the compaction wheels
