Abstract
The utility model relates to the technical field of farming holing devices, in particular to a rotary type holing mechanism. The rotary type holing mechanism is characterized by comprising a driving crank mounted on a rack, wherein the driving crank is hinged with one end of a buried holing rod which is connected with one end of a driven drag rod, the other end of the driven drag rod is mounted on the rack, and a return spring damping is arranged on the driven drag rod; and the driving crank, the buried holing rod, the driven drag rod and the rack are hinged to form a parallel four-bar mechanism. According to the rotary type holing mechanism, the driven rod equipped with the spring damping can further recover the shape of the parallel four-bar mechanism when the buried holing rod is not buried into soil, so that the buried holing rod is buried into the soil perpendicularly, the driven rod equipped with the spring damping can balance part of displacement in the horizontal direction after the buried holing rod is buried into the soil, and the horizontal displacement quantity of the buried rod is reduced; and with the adoption of the rotary type holing mechanism, the film hole size during seeding operation can be reduced, thus, the heat preservation and the wind resistance of a film are higher, and powerful guarantee is provided for increase of crop yield.
Description
Technical field
The utility model relates to cultivates cavitation device technique field, especially relates to a kind of swinging hole former.
Background technology
In prior art, the cavitation process that the hole former of type farming equipment advances in process at complete machine is: 1) move downward cavitation; 2) when moving downward, move backward with respect to complete machine, to ensure cave hole forming seeding; 3) move upward and return.Its fenestra size is to weigh the important parameter of operation quality, in order to be conducive to insulation and to improve wind resistance, is not affecting under the prerequisite of emerging, and membrane pore size should be the smaller the better; For fear of producing residual film, hole former bury and unearthed process in should realize straight cutting motion, vertically bury and be vertically unearthed, this requires the part of burying of hole former to have in the horizontal direction less displacement.After existing four function pivoted levers exist operation, membrane pore size is excessive, chooses film dyestripping serious, and heat insulating ability and the wind resistance of film are poor.
Summary of the invention
The purpose of this utility model is to avoid the deficiencies in the prior art that a kind of swinging hole former is provided, thereby effectively solves the problem of prior art.
For achieving the above object, the technical scheme that the utility model is taked is: described a kind of swinging hole former, be characterized in comprising rack-mounted driving crank, driving crank is connected with the cavitation bar that buries, the cavitation bar that buries is connected with driven drag strut one end, the driven drag strut other end is arranged in frame, on driven drag strut, is provided with back-moving spring; Described driving crank, the cavitation bar that buries, driven drag strut and frame are by hinged formation parallel four-bar linkage.
Described driving crank is done gyration and is driven bury cavitation bar and the revolution of driven drag strut.
The beneficial effects of the utility model are: described a kind of swinging hole former, and it is replaced by length because of the variable spring damping bar of condition by original follower lever, and the displacement of cavitation bar horizontal direction can reduce to bury.The cavitation bar that simultaneously buries does not enter follower lever that when ground is equipped with spring damping and also can recover the shape of parallelogram lindage, the guarantee cavitation bar that buries vertically buries, the follower lever that spring damping is housed after burying can balance the displacement of a part of horizontal direction, the horizontal displacement of the bar that reduces to bury.It can reduce membrane pore size in the time of seeding operation, makes like this heat insulating ability of film and wind resistance higher, for crop yield provides powerful guarantee.
Brief description of the drawings
Fig. 1 is structural principle schematic diagram of the present utility model.
In figure: 1. driving crank; 2. cavitation bar buries; 3. driven drag strut; 4. back-moving spring.
Embodiment
Below in conjunction with accompanying drawing, principle of the present utility model and feature are described, example, only for explaining the utility model, is not intended to limit scope of the present utility model.
As shown in Figure 1, described a kind of swinging hole former, be characterized in comprising rack-mounted driving crank 1, driving crank 1 is connected with the cavitation bar 2 that buries, the cavitation bar 2 that buries is connected with driven drag strut 3 one end, driven drag strut 3 other ends are arranged in frame, on driven drag strut 3, are provided with back-moving spring 4; Described driving crank 1, the cavitation bar 2 that buries, driven drag strut 3 and frame are by hinged formation parallel four-bar linkage.
Further, described driving crank is done gyration and is driven bury cavitation bar and the revolution of driven drag strut.
Described a kind of swinging hole former, driving crank circles for 1 time, and the cavitation bar 2 that buries also returns and circles, and completes time cavitation, the process of charging seed.In complete machine motion process, the cavitation bar 2 that buries keeps vertical with ground all the time.In cavitation bar 2 upper ends of burying, seeding unit is set, the seed of discharge falls into cavitation bar bottom inner chamber by grain conductor, and the cavitation bar lower end enforced opening that buries in the time reaching the seed level of regulation, falls under gravity in hole, cave the seed in inner chamber.It is replaced by length because of the variable spring damping bar of condition by original follower lever, and the displacement of cavitation bar horizontal direction can reduce to bury.The cavitation bar that simultaneously buries does not enter follower lever that when ground is equipped with spring damping and also can recover the shape of parallelogram lindage, the guarantee cavitation bar that buries vertically buries, the follower lever that spring damping is housed after burying can balance the displacement of a part of horizontal direction, the horizontal displacement of the bar that reduces to bury.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
