The driving mechanism comprises a rack, and a seeding head which is fixedly arranged on the rack, wherein the seeding head comprises a hole sowing rod which can vertically lift, a seeding tube parallel to the hole sowing rod, a seed tank which is horizontally arranged, and a seed sucker which can swing between the seed tank and the seeding tube; a sliding rail which is horizontally arranged is arranged on the rack below the seeding head; a tray is arranged on the sliding rail; a transverse beam is fixedly arranged on the rack below the tray; a cylinder frame is hinged to the transverse beam through a hinged shaft; a propulsion cylinder is fixedly arranged on the cylinder frame; an ejector rod is fixedly connected to a cylinder rod of the propulsion cylinder; a lower supporting plate which extends to the lower part of the cylinder frame is fixedly connected to the transverse beam; an adjusting bolt is arranged on the lower supporting plate through a thread; a positioning rod is fixedly arranged below the tray; positioning pits are arranged on the lower surface of the positioning rod. The driving mechanism is simple in structure and reliable in operation and can automatically correct the displacement error, and the design and production cost is reduced.
Description
Technical field
The utility model relates to a kind of agricultural machinery, specifically a kind of driving mechanism of pin type tray seeder.
Background technology
Pin type tray seeder is to the mechanical device on kind of dish by vegetable seeds program request, when its work, utilize can vertical lift the bar of attacking a vital point on the compost of kind of dish, put and plant cave, and utilize the suction kind device of aspiration principle that the seed in seed trough is picked up and put in sowing pipe, seed is slipped in kind of cave along sowing pipe.Because sowing is accurate, save seed consumption, there is good development prospect.In this pin type tray seeder course of work, need kind of a dish intermittence to move horizontally, traditional gear, tooth bar and belt transmissioning mode can be by the error accumulation of displacement, causes sowing inaccurate.As improve precision, reduce error and must cause increasing substantially of production cost.
Summary of the invention
The utility model provides a kind of simple in structure, the driving mechanism that can automatically revise the pin type tray seeder of displacement error for addressing the above problem, to reduce production costs, to improve equipment reliability of operation.
For achieving the above object, the utility model adopts following technical scheme:
The driving mechanism of a kind of pin type tray seeder described in the utility model comprises frame, be fixedly mounted on the seeding head in frame, described seeding head comprises the bar of attacking a vital point that can vertical lift, the sowing pipe be arrangeding in parallel with the bar of attacking a vital point, horizontally disposed seed trough and the suction kind device that can swing between seed trough and sowing pipe, in the frame of seeding head below with horizontally disposed slide rail, pallet is installed on slide rail, in the frame of described pallet below, be installed with crossbeam, on described crossbeam, be hinged with cylinder frame by hinge, on described cylinder frame, fixedly mount propulsion cylinder, on the cylinder rod of described propulsion cylinder, be fixedly connected with push rod, on described crossbeam, be fixedly connected with the bottom plate that extends to cylinder frame below, on described bottom plate, by screw thread, adjusting bolt be installed, below described pallet, be installed with backstay, the lower surface of described backstay is provided with positioning pit.
The stage casing of described push rod is with bending section.
Owing to having adopted said structure, this driving mechanism structure is simple, can automatically revise displacement error, reliable, is conducive to reduce design, production cost.
Brief description of the drawings
Fig. 1 is the structural representation of an embodiment of the utility model.
Fig. 2 is the plan structure schematic diagram of driving mechanism.
Embodiment
As shown in Figure 1 and Figure 2, the driving mechanism of a kind of pin type tray seeder described in the utility model comprises frame 1, is fixedly mounted on the seeding head in frame 1, described seeding head comprises the bar 2 of attacking a vital point, and the bar 2 of attacking a vital point the sowing pipe 3, the horizontally disposed seed trough 4 that be arranged in parallel and the suction kind device 5 that can swing between seed trough 4 and sowing pipe 3 that can vertical lift, in the frame 1 of seeding head below with horizontally disposed slide rail 6, pallet 7 is installed on slide rail 6, and pallet 7 is inserted kind of a dish for installing.In the frame 1 of described pallet 7 belows, be installed with crossbeam 8, on described crossbeam 8, be hinged with cylinder frame 9 by hinge, on described cylinder frame 9, fixedly mount propulsion cylinder 10, on the cylinder rod of described propulsion cylinder 10, be fixedly connected with push rod 11, the stage casing of described push rod 11 is with bending section, make the two ends angle in obtuse angle of push rod 11, can avoid like this propulsion cylinder 10 to install time, angle of inclination is excessive, can be conducive to again the propelling of push rod 11.On described crossbeam 8, be fixedly connected with the bottom plate 12 that extends to cylinder frame 9 belows, on described bottom plate 12, by screw thread, adjusting bolt 13 is installed, the upper end of described adjusting bolt 13 withstands on below cylinder frame 9, the angle of pitch that rotation adjusting bolt 13 can adjusting cylinders frame 9.Below described pallet 7, be installed with backstay 14, the lower surface of described backstay 14 is provided with positioning pit 15.
When work, adjust the angle of pitch of cylinder frame 9 by adjusting bolt 13, propulsion cylinder 10 promotes push rod 11 and moves obliquely upward when work, and the top of push rod 11 is injected in a positioning pit 15, promote pallet 7 station that advances, propulsion cylinder 10 returns are waited for next work period.After the sowing of seeding head has been moved, propulsion cylinder 10 task again, push rod 11 injects in next positioning pit 15, then pallet 7 is advanced to a station, by that analogy, until the whole sowings of kind dish are complete.
