Background technology:
Horse hoof is generally grown in shallow water Tanaka, three April long Seedling, stem straight rise, there is no branch and leaf, shape as dragon must, when mechanical harvest is carried out for Horse hoof, the general top layer earth first grown by Horse hoof and rice shoot are rooted out, and top layer earth carries out after rooting out ploughing operation of being unearthed again.
It is unearthed Horse hoof is ploughed, most employing is manually excavated, the employing scraper bowl also having or pears etc., hand labor intensity is big, the weight of instrument is relatively large, installing/dismounting is relatively inconvenient, therefore efficiency of crop relatively low under, do not have not yet a kind of rationally to plough unearthed structure to ensure that efficiency of crop significantly promotes.
Summary of the invention:
In order to make up prior art problem, it is an object of the invention to provide a kind of Horse hoof with fine tuning structure and plough excavation device, novel in structural design, it is possible to carry out the fine motion of grilled teeth when ploughing Horse hoof top layer earth, improve the efficiency ploughed.
Technical scheme is as follows:
Horse hoof with fine tuning structure ploughs excavation device, including rotating the rotating shaft being installed on bearing block, it is characterized in that: described rotating shaft is provided with the mounting disc of two interval suits, on described mounting disc outer wall, radially spaced distribution has several gripper shoes, corresponding gripper shoe is rotatablely equipped with mounting rod, mounting rod is intervally distributed with several grilled teeth, the described rotating shaft between one of them mounting disc and bearing block is set with concavo-convex dish, the outer wall of concavo-convex dish and bearing block fixes, concavo-convex dish be arranged over downwardly open U-shaped installing rack, the opening of U-shaped installing rack is rotatablely equipped with pulley, the upper surface of U-shaped installing rack is provided with guide post, guide post is set with pilot sleeve, the outer wall of pilot sleeve is fixed by connecting rod with corresponding gripper shoe outer wall, the guide post of the lower section of pilot sleeve is set with spring, lower spring end withstands described U-shaped installing rack, described guide post top is hinged with connecting plate, connecting plate front end is hinged with fixing plate, the end of fixing plate fixes with described mounting rod extension.
The described Horse hoof with fine tuning structure ploughs excavation device, it is characterised in that: described several grilled teeth tilt to install along the rotation direction of rotating shaft.
The described Horse hoof with fine tuning structure ploughs excavation device, it is characterised in that: the two ends of described pulley outer wall are provided with the spacing preiection of annular, and the interval between spacing preiection is slightly larger than the thickness of concavo-convex dish.
The described Horse hoof with fine tuning structure ploughs excavation device, it is characterised in that: described guide post upper end is provided with contiguous block, and contiguous block and connecting plate are hinged.
The invention have the advantage that
1, present configuration is novel in design, and overall structure lighter in weight uses dexterity, mounts and dismounts more convenient, practical;
2, the reasonable in design of the present invention, by being arranged on the concavo-convex dish in rotating shaft, concavo-convex dish and bearing block are relatively fixed, and coordinate the structures such as pulley, guide post, pilot sleeve to realize the fine motion of grilled teeth when ploughing earth, improve efficiency when ploughing unearthed;
3, the present invention is by pulley and the laminating of concavo-convex dish, drives the grilled teeth fine motion on mounting rod in rolling process, and pulley both sides are provided with annular stop projection, good stability;
4, the present invention carries out ploughing unearthed in the process that rotating shaft drives mounting disc to rotate, and meanwhile, fine tuning structure drives grilled teeth to carry out fine motion, cooperates, improves the efficiency ploughed.
Detailed description of the invention:
Referring to Fig. 1:
Horse hoof with fine tuning structure ploughs excavation device, including rotating the rotating shaft 2 being installed on bearing block 1, rotating shaft 2 is provided with the mounting disc 3 of two interval suits, on mounting disc 3 outer wall, radially spaced distribution has several gripper shoes 4, corresponding gripper shoe 4 is rotatablely equipped with mounting rod 5, mounting rod 5 is intervally distributed with several grilled teeth 6, rotating shaft between one of them mounting disc 3 and bearing block 2 is set with concavo-convex dish 7, the outer wall of concavo-convex dish 7 and bearing block 1 fixes, concavo-convex dish 7 be arranged over downwardly open U-shaped installing rack 8, the opening of U-shaped installing rack 8 is rotatablely equipped with pulley 9, the upper surface of U-shaped installing rack 8 is provided with guide post 10, guide post 10 is set with pilot sleeve 11, the outer wall of pilot sleeve 11 is fixed by connecting rod 12 with corresponding gripper shoe 4 outer wall, the guide post 10 of the lower section of pilot sleeve 11 is set with spring 13, U-shaped installing rack 8 is withstood in spring 13 lower end, guide post 10 top is hinged with connecting plate 14, connecting plate 14 front end is hinged with fixing plate 15, the end of fixing plate 15 fixes with mounting rod 5 extension.
Several grilled teeth 6 tilt to install along the rotation direction of rotating shaft.
The two ends of pulley 9 outer wall are provided with the spacing preiection 16 of annular, and the interval between spacing preiection 16 is slightly larger than the thickness of concavo-convex dish 7.
Guide post 10 upper end is provided with contiguous block 17, and contiguous block 17 and connecting plate 14 are hinged.
