Abstract
The utility model relates to the implanted device technical field in agricultural machinery, especially relates to a kind of direct insertion hole former.Comprise frame, hinged driving lever and the follower lever of being provided with in frame described in being characterized in, on driving lever, be provided with the driving lever slide block of translation constraint, on follower lever, be provided with the follower lever slide block of translation constraint, bunch planting bar and driving lever slide block and follower lever slide block are hinged respectively, in frame, be also provided with the bidirectional parallel operating slide block retraining with the translation of bunch planting bar upper end, bidirectional parallel operating slide block and frame translation constraint, described bunch planting bar, driving lever, follower lever and frame is by moving parallel four connecting rods of hinged formation.It is replaced by length because of the variable spring damping bar of condition by original follower lever, and the displacement of bar horizontal direction can reduce 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.
Description
Technical field
The utility model relates to the implanted device technical field in agricultural machinery, especially relates to a kind of direct insertion hole former.
Background technology
In prior art, the cavitation process that the cavitation device 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, cavitation device bury and unearthed process in should realize straight cutting motion, vertically bury and be vertically unearthed, this requires the part of burying of cavitation device 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 defect of prior art and a kind of direct insertion hole former is provided, and efficiently solves the problem that prior art exists.
For achieving the above object, the technical scheme that the utility model is taked is: the direct insertion hole former of described one, comprise frame, hinged driving lever and the follower lever of being provided with in frame described in being characterized in, on driving lever, be provided with the driving lever slide block of translation constraint, on follower lever, be provided with the follower lever slide block of translation constraint, bunch planting bar and driving lever slide block and follower lever slide block are hinged respectively, in frame, be also provided with the bidirectional parallel operating slide block with bunch planting bar upper end translation constraint, bidirectional parallel operating slide block and frame translation constraint, described bunch planting bar, driving lever, follower lever moves parallel four connecting rods with frame by hinged formation.
Described bunch planting bar bottom is provided with duck-beak type indenting tool.
The described frame tractor that was connected with tractor drives and travels forward, and described follower lever is spring damping bar, and driving lever does gyration and drives the motion of bunch planting bar and follower lever.
The beneficial effects of the utility model are: the direct insertion hole former of described one, and it is replaced by length because of the variable spring damping bar of condition by original follower lever, and the displacement of bar horizontal direction can reduce to bury.The 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 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.
Shown in figure: 1. frame; 2. bidirectional parallel operating slide block; 3. bunch planting bar; 4. driving lever; 5. driving lever slide block; 6. follower lever; 7. follower lever slide block; 8. duck-beak type indenting tool.
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, the direct insertion hole former of described one, comprise frame 1, hinged driving lever 4 and the follower lever 6 of being provided with in frame 1 described in being characterized in, on driving lever 4, be provided with the driving lever slide block 5 of translation constraint, on follower lever 6, be provided with the follower lever slide block 7 of translation constraint, bunch planting bar 3 is hinged respectively with driving lever slide block 5 and follower lever slide block 7, in frame 1, be also provided with the bidirectional parallel operating slide block 2 with the 3 upper end translation constraints of bunch planting bar, bidirectional parallel operating slide block 2 and frame 1 translation constraint, described bunch planting bar 3, driving lever 4, follower lever 6 moves parallel four connecting rods with frame 1 by hinged formation.
Described bunch planting bar 3 bottoms are provided with duck-beak type indenting tool 8.
Described frame 1 tractor that was connected with tractor drives and travels forward, and described follower lever 6 be spring damping bar, and driving lever 4 makees gyration drive bunch planting bar 3 and follower lever 6 moves.
The direct insertion hole former of described one, when work, driving lever circles for 4 times, and bunch planting bar 3 also returns and circles, and completes time cavitation, the process of charging seed.In complete machine motion process, bunch planting bar 3 keeps vertical with ground all the time.Bunch planting bar 3 lower ends are provided with duck-beak type indenting tool 8, complete sowing by duck-beak type indenting tool 8.
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.
