Abstract
The utility model mainly relates to the protective tillage equipment, in particular to an anti-blocking device for a no-tillage seeder. A spring-tooth anti-blocking device for a no-tillage seeder comprises a machine rack (1), a furrow opener base (3) and a furrow opener (9), and is characterized in that a spring-tooth anti-blocking device (2) is arranged on the machine rack (1) and in front of the furrow opener (9); the spring-tooth anti-blocking device (2) is arranged on the machine rack (1) by the furrow opener base (3) through a U-shaped bolt (21); a support plate (22) is arranged on the furrow opener base (3) through a bolt (23); one end of a spring tooth (24) is connected with the support plate (22) through a pin shaft (25), while the other end of the spring tooth (24) is connected with the furrow opener (9). The spring-tooth anti-blocking device has simple structure and low manufacturing cost, which makes use of the nonlinear deformation of the spring tooth to suppress the straw stalks before the furrow opener for a short period of time, so as to prevent the furrow opener being bound with grass and achieve the anti-blocking purpose.
Description
Technical field:
The utility model relates generally to the conservation tillage facility, is specifically related to the no-tillage seeding machine anti-block apparatus.
Background technology:
No-tillage seeding machine is the crucial facility in the zero tillage machinery equalization.For adapting to, require no-tillage seeding machine to have higher anti-blocking performance in the operation of stubble mulched ground upper seeding wheel.The anti-block apparatus of no-tillage seeding machine mainly contains cut-off type and branch open form both at home and abroad at present.The cut-off type anti-block apparatus is mainly used in the bigger situation of stalk overlay capacity, but its power consumption is big, noise big, work under bad environment.
Branch open form anti-block apparatus mainly contains cutting disc pressurization grass wheel combined type anti-block apparatus, the gear teeth are dialled careless type anti-block apparatus, chaffcutter dish+anti-block apparatus such as gear tooth-type grass stick, because above-mentioned minute open form anti-block apparatus complex structure, when the stalk overlay capacity is big, stopping up inevitably can appear in its anti-block apparatus place, becomes new obstruction source.
Summary of the invention:
The purpose of this utility model is to avoid the deficiencies in the prior art part and a kind of no-tillage seeding machine elastic claw type anti-block apparatus is provided, simple in structure, the low cost of manufacture of elastic claw anti-block apparatus, the stalk of the nonlinear deformation that this device utilizes elastic claw before to plough produces the short time compacting, prevent that plough from twining grass, under the more condition of the little floating grass of stalk overlay capacity, have trafficability characteristic preferably.
The purpose of this utility model can be by realizing by the following technical solutions: a kind of no-tillage seeding machine elastic claw type anti-block apparatus, include frame (1), plough seat (3), plough (9), on described frame (1), plough (9) the place ahead is provided with elastic claw anti-block apparatus (2).Described elastic claw anti-block apparatus (2) is that described plough seat (3) is arranged on the frame (1) by U-bolt (21), gripper shoe (22) is arranged on the plough seat (3) by bolt (23), one end of elastic claw (24) links to each other with gripper shoe (22) by bearing pin (25), and the other end of elastic claw (24) links to each other with plough (9).
Described no-tillage seeding machine elastic claw type anti-block apparatus, described elastic claw (24) forms torsion spring by the curling 1-3 circle of an end that bearing pin (25) links to each other with gripper shoe (22).Torsion spring is partly used finger setting during installation, leaves the gap of 2～3mm, and torsion spring is connected on the fixed mount with bolt, makes elastic claw certain axial movement value be arranged to give full play to the effect of torsion spring.
The beneficial effects of the utility model are: when carrying out the no-tillage seeding operation, one cover elastic claw anti-block apparatus is installed before each plough of no-tillage seeding machine, since elastic claw to plough before stalk keep the chip hold down of certain hour section, when making plough pass through the place ahead stalk, the relative ground of stalk transfixion, plough passes through the place ahead stalk with speed of drilling, elastic claw is shut down the stalk that swelling hangs on the plough from plough, make the plough straw winding, reach anti-blocking purpose, at 6000kg/hm
2Facility can pass through smoothly under the stalk overlay capacity, finish seeding operation.
Description of drawings:
Fig. 1 is the utility model elastic claw type anti-block apparatus structural representation;
Fig. 2 is the structural representation of the utility model embodiment.
Embodiment:
Be described in further detail below in conjunction with the most preferred embodiment shown in the accompanying drawing:
