Embodiment
The total design of the present invention is, at seeding and film laminating machine front portion assembling ripple cylinder, pressure builds many fins on the ground, strengthens the compression strength on ground, prevents facility from sinking and gathers around soil, realizes steadily mulch sowing operation fast.Around this design, introduce four kinds of embodiments below:
The first embodiment: as shown in Figure 1, this anti-sunken tectorial seeder has the frame 1 of a frame-type, frame 1 has been provided with mounting point above, and frame 1 is equipped with fertile case 2, ground film rack 3 above, plants case 5, seed tray 6, trailing bar 7, pressing wheel 8, parts such as ditching-fertilizing device 10 grade.Ground film rack 3 installs mulch film spool 4 above, and mulch film 9 twists on mulch film spool 4.The most outstanding feature of this facility is: install a cylinder 11 in the front lower place of frame 1 by axle bed.Composition graphs 2, Fig. 3 are visible, and cylinder 11 is hollow circular cylinders of a pressing metal plates, and the diameter of cylinder 11 changes repeatedly, cylinder wall is formed many ripples 12.For ease of illustrating, the maximum gauge top of cylinder 11 is called crest 13, and minimum diameter top is called trough 14.Ripple 12 recommended parameter is: height is 25-35mm about, wide about 55-65mm, and crest fillet diameter is about 5-10mm, and trough arc diameter is about 12-18mm, the round and smooth connection of crest 13 trough 14.
During work, as shown in Figure 4, this facility are articulated in after tractor, and the rotating shaft of cylinder 11 is by the fertile case fertilizer of chain-driving, and the ground that cylinder 11 rolls across extrudes branched strip impression, plastic mulching is on impression, seed tray 6 below rolls and carries out punching sowing on mulch film 9, and the pressing wheel 8 of both sides pushes down mulch film 9 subsequently, and covering device 7 covers mulch film 9 both sides soil, facility can not be gathered around soil and sink, can the operation of stable and continuous.
Why can strip impression prevent facility from sinking? initial analysis is as shown in Figure 5: cylinder 11 is in rolling process, each crest 13 first kiss the earth, space in instant trough 14 is not yet filled, soil both sides pressurized in trough 14, inner underside is pointed in the direction of pressure, and the reaction force of soil is outside upside, by the restriction of cylinder wall, the soil of both sides to upper direction in trough, can only finally be full of trough 14.If cylinder does not have ripple 12, when pressing down, soil can not move upward, and can only be pressed against front, will inevitably cause and gather around soil, and when ripple cylinder 11 presses down, the space of trough 14 allows pressurized soil to move upward, and can not travel forward, thus there will not be and gather around native phenomenon.When cylinder 11 presses down beginning, between two crests 13, institute is a rectangle to soil profile, it is then a subtriangular space when trough 14 is full of, rectangular area is much larger than wide contour triangle area, in other words a lot of soil is extruded in a very little space, its density and intensity can significantly improve, and bearing capacity significantly strengthens.From the situation of whole cylinder 11, as shown in Figure 6, the right section of soil pressurized front roll is rectangle, and the top edge line finally formed as shown in Figure 7 is the rectangle of wave, the soil of its wave breach has been compressed in the middle of fin, and the density of fin and intensity must increase.Section left after cylinder is corrugated impression, is equivalent to arrange many in the below of facility and strengthens rib, be enough to the pressure of keeping out facility.First the facility arrived subsequently will flatten the impression of projection, just can press down subsequently, equal to have occurred a buffering course, guarantee passing through smoothly of facility.
Meanwhile, due to the counter motion of upper layer of soil when ripple cylinder 11 presses down, effectively blocked the biography down of cylinder 11 pressure, the soil density change below impression is very little, still very loose, namely defines excess in the upper and deficiency in the lower perfect condition.
The second embodiment: the facility shown in Fig. 8 are improved on the basis of the first embodiment, a water pipe rack 15 is increased before mulch film spool 4 above frame 1, water pipe rack 15 supports a water pipe spool 16, water pipe spool 16 coils soft plastic film water pipe above, water wall gets many micropore holes by laser, drip irrigation can be carried out to crop.Before this, this water pipe by artificial existing laying before facility, can only add operating cost.After have employed said structure, can water pipe is pressed in below mulch film 9, once completed the laying operation of mulch film and water pipe by facility, operating efficiency significantly improves, and operating cost significantly reduces.
The third embodiment: the facility shown in Fig. 9 increase a set of press mold frame 17 in the below of frame 1.Visible in conjunction with Figure 10, the workpiece of press mold frame 17 is cylindrical pressing film rollers 20, and the length of pressing film roller 20 is equal to or greater than the working width of the wide i.e. monomer facility of film, parallels with the mulch film spool 4 of top.Pressing film roller 20 two ends are contained in the front end of two forks 19 by rotating shaft, the rear end of two forks 19 by rotating shaft respectively with two connecting rod erect 18 phase hinges, the upper end of connecting rod 18 through the fixed cover 24 be connected with frame, and is located by jackscrew.Often prop up the rear upside of fork 19 all by rotating shaft and the depression bar erect a 21 phase hinge, fitting nut outside depression bar 21, more than nut cover has stage clip 22, through a sleeve pipe 22 be connected with frame, and can slide in the upper end of depression bar 21 in sleeve pipe 22.The fixed position of adjustment connecting rod 18, or the position of adjustment depression bar top nut, can adjust the downforce of pressing film roller 20, pressing film roller 20 is worked under the state of the best.During work, mulch film 9 first through pressing film roller 20, then extends to below seed tray 6, and punching is after planting pressed by the pressing wheel 8 of both sides below again, and earthing pressure is buried subsequently.Obviously, the expansion of mulch film no longer relies on pulling of seed tray 6, but is pulled by pressing film roller 20.Compared with seed tray 6, the tension and compression area of pressing film roller 20 pairs of mulch films 9 is large, and not damaged, makes the laying of mulch film 9 more smooth, and punch position and size are more accurate, and water retention property and durability significantly promote.
The improvement of film pressing device improves the flatness of mulch film, but this state will be fixed up, and also needs the cooperation of covering device 7.According to agriculture requirement, not only mulch film both sides need earthing, and above mulch film, most of area all needs the earthing covering 10-20mm.Because mulch film is very thin, easily scratch, the covering device in past can only at mulch film both sides earthing, can't on mulch film earthing.In order to address this problem, this example adopts a kind of covering device 7 of many point of adjustment.As shown in Figure 9, this covering device 7 is also the afterbody being contained in facility, in conjunction with Figure 12,13 visible, covering device 7 has two, is located at the both sides of mulch film respectively, and each covering device 7 has a swing pipe 26, rotating shaft 25 hinge is passed through in frame 1 in swing pipe 26 front end, the other end of swing pipe 26 inserts adjusts stock 27, adjusting stock 27 to adjust length by pulling and pushing in swing pipe 26, going up in position and being fixed by jackscrew.Adjust the other end of stock 27 to be connected a sleeve 28, plug-in mounting vertical rod 29 inside sleeve 28, a slice trailing bar 30 is equipped with in the lower end of vertical rod 29, and vertical rod 29 can move up and down in sleeve 28, and rotatably, goes up in position and fixed by jackscrew.The downside of swing pipe 26 is respectively equipped with multiple positioning hole 31 with relative frame position, has extension spring 32 to draw mutually between both sides positioning hole 31, and extension spring 32 adjusts the size of pulling force by conversion positioning hole 31.Had this covering device 7, just can adjust multi-mode operation parameter as required, can not only at mulch film both sides earthing, and can on mulch film earthing, the highly difficult routine of even earthing 10mm and not scratch mulch film can be competent at.
4th kind of embodiment: the facility shown in Figure 14, Figure 17 are provided with a set of film frame 33 for subsequent use, in conjunction with Figure 15,16 visible, film frame 33 for subsequent use has two suspension rods 34, suspension rod 34 front end hinge is in frame, rear portion is hung in frame by hoist cable 35, hoist cable 35 adjustable length, rear end mounts a film spool 36 for subsequent use by rotating shaft.The effect of this device is that available backup film continues to be routed to the edge of a field, then changes mulch film spool, avoids moving to take mulch film at a distance, time saving and energy saving, ensure that the continuity of operation, improves operating efficiency when the mulch film 9 of mulch film spool 4 is finished in operation midway.
