Abstract
Description
Technical Field
[0001] This utility model relates to the field of agricultural machinery technology, and in particular to a floating compaction adjustment system for a clay grain seeder. Background Technology
[0002] A grain seeder performs rotary tillage at the front, sowing at the rear, and then compaction. The grain seeder includes a rotary tillage system and a sowing and compaction system, which in turn includes a furrowing system, a sowing system, and a compaction system. Currently, the compaction system consists of a horizontally positioned compaction roller, which is rotatably connected to the lower rear of two longitudinally positioned, parallel, and spaced-apart side plates of the sowing and compaction system. The main drawback of this compaction system is that the height of the compaction roller relative to the sowing and compaction system is fixed, making it impossible to adjust the compaction pressure for different ground conditions, and therefore unable to achieve varying compaction pressures as needed. Utility Model Content
[0003] This invention addresses the shortcomings of existing technologies by proposing a floating compaction adjustment system for clay grain planters that enables different pressure compaction of the ground.
[0004] The present invention achieves its technical objectives through the following technical solutions.
[0005] A floating press adjustment system for a clay grain seeder is located at the rear of the seeding press system. It includes a horizontally placed press roller, which is rotatably connected to the lower part of the rear of two longitudinally placed and parallel press roller connecting side plates. Its improvement lies in that the press roller is adjusted by the press pressure adjustment system.
[0006] Furthermore, the pressing pressure regulating system includes two hydraulic regulating units; each hydraulic regulating unit includes a hydraulic cylinder with a longitudinal central axis; the front end of the pressing roller connecting side plate is hinged to the lower middle part of the rear of the sowing pressing system side plate; the upper part of the rear of the sowing pressing system side plate is rotatably connected to a hydraulic cylinder connecting block with a transverse central axis; the cylinder body of the hydraulic cylinder is hinged to the upper part of the rear of the pressing roller connecting side plate, and the piston rod of the hydraulic cylinder is connected to the hydraulic cylinder connecting block; the hydraulic cylinder, through the extension and retraction of the piston rod, can drive the pressing roller to rotate around the center where the front end of the pressing roller connecting side plate is hinged to the lower middle part of the rear of the sowing pressing system side plate.
[0007] Furthermore, the piston rod of the hydraulic cylinder is clearance-fitted through the hydraulic cylinder connecting block, and two springs are provided on the piston rod of the hydraulic cylinder to clamp the hydraulic cylinder connecting block in the middle. The piston rod of the hydraulic cylinder is provided with a limiting structure at the opposite ends of the two springs.
[0008] Compared with the prior art, this utility model has the following advantages:
[0009] 1. The pressing roller can be adjusted by adjusting the pressing pressure system to adjust the pressing pressure on the ground as needed to ensure the pressing effect. Appropriate pressing pressure will improve the moisture retention and frost resistance of the seedbed.
[0010] 2. Two springs are installed on the piston rod of the hydraulic cylinder to clamp the hydraulic cylinder connecting block in the middle. During operation, the bidirectional elastic buffering realizes floating pressing and further ensures the pressing effect. Attached Figure Description
