In order to address this problem, people have taked the mode of double plate trench digging, for example, application number is that 99234552.9 Chinese patent promptly discloses the two disk seed manures of a kind of large-scale power traction sower and divides sowing and applying furrow opener, purpose is the shallow seed of executing of side position deep placement chemical fertilizer, fertile layering, raising emergence rate and the output of planting.Main composition is trench digging circular disc and fertilizer delivering pipe and grain tube to be arranged, fertilizer delivering pipe and grain tube bottom assembling branch kind of fittings body and secondary ditching shovel on the opener shank.
The plough of above-mentioned prior art does not all deviate from " wedge shape " structure thinking of ploughing plough, complex structure not only, and can't make the soil after the farming keep original form substantially, be unfavorable for environmental protection.
Summary of the invention
The objective of the invention is to: at the shortcoming that above prior art exists, proposes a kind ofly can under the prerequisite of the original form of basic maintenance soil, guarantee to form required spaced trenches, and double-station twin-disk colter simple in structure.
In order to reach above purpose, at first designed the plough of coaxial parallel double disc structure, attempt to utilize the structure of trench digging disk self, leave ditch seam at interval, so that sowing one of therein, another fertilising, thus promptly avoid " burn and plant ", can behind seeding and fertilizing, keep original form of soil again as far as possible.Yet, facts have proved that the problem that this coaxial double plate plough exists is in practicality, the soil between the two trench digging dishes is easy to be taken up by integral body, and the result had both destroyed required parallel interval groove, had destroyed original form of soil again.
The applicant finds through experimental study, and the basic reason that the soil between the coaxial two trench digging dishes is taken up by integral body is two dish medial surfaces to due to the synchronous frictional force of soil.On this understanding basis, double-station twin-disk colter of the present invention is proposed, comprise cutterhead holder and at least one pair of circular beater plate, vertical both sides of described cutterhead holder are installed the spaced and parallel cutter axis that stretches to the both sides respectively, and rotatable cutterhead is installed respectively on the described cutter axis.
The present invention further improves, the parallel cutter axis at described two intervals is in level when working with its axial connecting line mode is fixed on the cutterhead holder, the cutterhead seat of pipe shape is installed by bearing respectively on two cutter axis, described cutterhead seat length direction middle part extends outward the flange ring with its axis normal, fixation cutter head on the described flange ring.
Plough of the present invention is not only simple in structure, and owing to two trench digging cutterheads are parallel to each other but disalignment, therefore will produce different directions, different big or small friction force to soil therebetween when rotating, thereby can avoid soil to dig with cutterhead, the result can keep the original form of soil substantially, leave parallel spaced trenches, be convenient to follow-up fertilising, seeding operation.
Description of drawings
The present invention is further illustrated below in conjunction with accompanying drawing.
Fig. 1 is the structural representation of one embodiment of the invention.
Fig. 2 is the sectional structure schematic diagram at Fig. 1 embodiment cutterhead position.
Embodiment
Embodiment one
Present embodiment is the double-station twin-disk colter supporting with no-tillage seeding machine, its structure as depicted in figs. 1 and 2, cutterhead holder 1 is L-shaped, suffered soil resistance direction is suitable during the work of the angle of inclination, long limit on its top and cutterhead, with about 60 degree of horizontal angle.The minor face basic horizontal of bottom, two cutter axis 1-4 spaced apart that stretch to the both sides respectively of its vertical both sides fixed installation, support by inside and outside two bearings 1-5 respectively on two cutter axis 1-4 pipe shape cutterhead seat 1-3 is installed, two cutterhead seat 1-3 cylindrical length directions middle part extends outward the flange ring with its axis normal, fixedly mounts parallel circular beater plate 1-2 by securing member respectively on the inner surface of flange ring.The periphery of circular beater plate 1-2 is shaped on cutting edge, is convenient to trench digging.
Fixedly connected with the lower end of the elastic cylindrical pin 2 that tilts in the upper end, long limit of cutterhead holder 1, the upper end of this elastic cylindrical pin is in same horizontal position substantially with two cutter axis 1-4 and is inserted in the angling hole of movable connecting rod 3 rear end correspondences, by axle position ring washer, realize axial constraint each other, circumferentially can relatively rotate, thereby constitute automatic guide mechanism.The lower end of the front end of movable connecting rod 3 and Connection Block 7 is hinged, between the back upper end of Connection Block 7 and movable connecting rod 3 middle parts spring 5 is housed.On the spring lever 6 that this spring housing is hinged in lower end and movable connecting rod 3 middle parts, the upper end passes Connection Block 7.Spring base 4 is housed on the step of this spring lever bottom, blocks the lower end of spring 5, Connection Block 7 is withstood in the upper end of spring 5.Nut is screwed in the upper end of spring lever 5 after Connection Block 7 passes, can regulate the initial position of two cutterheads, and forms spring buffer mechanism, and to the downforce of trench digging cutterhead.The front end of Connection Block 7 is equipped with involutory (the being commonly called as Hough) Connection Card 8 that is used to connect no-tillage seeding machine.
