Description
Technical Field
The utility model belongs to agricultural machinery, and mainly relates to a land wheel profiling mechanism of a seeder.
Background
At present, when a seeding machine equipped with a seeding device is used for seeding, the seeding rotation power of the seeding device is the rotation power from a land wheel assembly of the seeding machine, so that the effective and reliable compaction contact between the land wheel of the seeding machine and the land surface is one of key technical conditions for guaranteeing the seeding quality of the seeding machine. However, due to the defects and defects in structural design, the hydraulic oil cylinder of the conventional seeding machine adopting a hydraulic traveling system structure is fixedly arranged on the frame assembly of the seeding machine, and is locked during seeding operation, so that the ground wheel assembly cannot perform and finish the up-and-down profiling motion along with the ground of the field on the frame assembly of the seeding machine, namely, the ground wheel assembly is easy to break away from contact with the ground of the field, the seeding machine stops seeding operation due to no rotary driving power source, the seeding operation quality is greatly influenced and reduced, miss seeding is caused, and particularly, when the phenomenon occurs on the large multi-row seeding machine, the number of seedlings per unit area is greatly reduced, and the yield is reduced.
Disclosure of Invention
The utility model aims at solving the problems in the prior art, combines the practical requirements of the operation of a seeding machine with a hydraulic traveling system structure, develops and designs a compression spring type anti-slip profiling compacting mechanism for the ground wheel of the seeding machine, and achieves the purposes of good floating profiling effect of the ground wheel assembly of the seeding machine, avoiding and eliminating the slip or stall of the ground wheel assembly caused by insufficient grounding pressure or separation from contact with the ground in the field, ensuring the seeding quality of the seeding machine and improving the adaptive capacity of the operation of the seeding machine.
The basic design of the utility model is as follows: a hanging support frame is fixedly arranged on the rear part of a frame assembly of the seeder and above a land wheel assembly, a pin shaft is fixedly arranged on the upper side part of the hanging support frame, a strip-shaped through hole is vertically formed in the upper end part of a hydraulic cylinder, the hydraulic cylinder can be hung and supported on the hanging support frame in a vertically sliding manner through the strip-shaped through hole and the pin shaft in a vertically sliding manner, an oil cylinder rod of the hydraulic cylinder is hinged with the land wheel assembly, a lower seat plate is fixedly sleeved on the lower side part of the hydraulic cylinder, an upper seat plate is sleeved on the upper side part of the hydraulic cylinder in a vertically moving manner and is in contact fit below the pin shaft, a pressure spring is sleeved on the outer part of the hydraulic cylinder, and the upper end and the lower end of the pressure spring are respectively in extrusion contact fit with the upper seat plate and the lower seat plate, so that a land wheel pressure spring type anti-slip profiling compacting mechanism of the seeder is formed.
The utility model has novel, simple and reasonable structure, can ensure that the land wheel assembly is reliably and effectively compacted and contacted on the field land all the time, avoids and eliminates the phenomenon of skidding or stalling of the land wheel assembly, has strong capability of adapting to the field land condition, has quick profiling action and ensures the sowing operation quality of the sowing machine.
Drawings
FIG. 1 is a schematic diagram of the overall structure of a compression spring type anti-slip profiling compacting mechanism of a ground wheel of a seeder;
fig. 2 is an enlarged view of the F portion in fig. 1.
Part number description in the drawings:
1. the seeder comprises a seeder frame assembly, 2, a hanging support frame, 3, a hydraulic cylinder, 4, a land wheel assembly, 5, a lower seat plate, 6, a pressure spring, 7, an upper seat plate, 8, a pin shaft, 9 and a strip-shaped through hole.
Detailed Description
Embodiments of the present utility model will be described in detail below with reference to the accompanying drawings. The utility model provides a seeder land wheel pressure spring type profile modeling compaction mechanism that skids that prevents, includes seeder frame assembly 1 and land wheel assembly 4, land wheel assembly 4 can swing from top to bottom ground articulates and installs on the rear side lower part of seeder frame assembly 1 on the rear portion of seeder frame assembly 1, be located the top position department of land wheel assembly 4 and adorn fixedly and hang support frame 2, round pin axle 8 is adorned fixedly on the upside position of hanging support frame 2, vertically offer bar through-hole 9 on hydraulic cylinder 3 upper end, but through bar through-hole 9 and round pin axle 8 relatively slip ground insert the fit with hydraulic cylinder 3 can hang the support with the ground and install on hanging support frame 2 from top to bottom, hydraulic cylinder 3's hydro-cylinder pole is articulated with land wheel assembly 4, and lower bedplate 5 fixed cover is joined in marriage on the downside of hydraulic cylinder 3, and upper bedplate 7 can be the ground suit on the upside of hydraulic cylinder 3 from top to bottom to be located round pin axle 8 below and be contact fit, is outside upper pressure spring 6, upper end and lower end of pressure spring 6 are respectively with upper bedplate 7 and lower bedplate 5 extrusion fit.
During operation, the hydraulic cylinder 3 is extended by the cylinder rod to ensure that the land wheel assembly 4 is reliably compacted on the field surface and is in close contact with the field surface, then the hydraulic cylinder 3 is locked, at the moment, the pin shaft 8 is positioned at the lowest end part of the strip-shaped through hole 9 of the hydraulic cylinder 3, meanwhile, the pressure spring 6 is extruded between the lower seat plate 5 and the upper seat plate 7 and the pin shaft 8 to increase the pressure, and the land wheel assembly 4 reliably rotates under the action of field resistance in the forward movement of the frame assembly 1 of the seeder to drive the seed sowing device to seed; when the field land surface is uneven and concave, under the combined action of the pressure spring 6 and the total weight of the land wheel assembly 4, the hydraulic cylinder 3, the upper seat plate 7 and the lower seat plate 5, and under the matched control of the pin shaft 8 and the strip-shaped through hole 9, the land wheel assembly moves rapidly downwards along with the underground concave surface of the field land, always keeps reliable compaction contact with the field land, realizes profiling movement, prevents the land wheel assembly 4 from reducing the contact capacity with the land or separating from contact, avoids and eliminates slipping or stalling of the land wheel assembly 4, and ensures the seeding operation quality of a seeding machine.
