Specific embodiment

The utility model is described in further detail with reference to the accompanying drawings and examples, to enable those skilled in the art Refer to the instruction text can be implemented accordingly.

As shown in Figs. 1-2, the utility model provides a kind of weeding system, comprising:

Rail mechanism comprising parallel side-by-side is layed in a plurality of long rails 1 in farmland at equal intervals, it is generally desirable to phase Spacing between adjacent two long rails 1 can be preset in 15~30 meters, and farmland is divided into n-1 specification by n long rails 11 Identical standardization plot, the rail mechanism further include that parallel side-by-side is layed at least two cross tracks 2 in farmland, Wherein, at least two cross tracks 2 are transversely to the machine direction the setting of track 1；

Mobile platform 3, across on adjacent two long rails 1, the lower section of the mobile platform 3 is rotatably provided with The two groups of wheel groups 4 moved along adjacent long rails 1 or adjacent transverse track 2, be provided on the mobile platform 3 telescopic rod 5 with Jacking the mobile platform 3 makes two groups of wheel groups 4 de-orbit, and makes the mobile platform 3 both can be adjacent to rotate two groups of wheel groups 4 It is mobile on two long rails 1 to be moved on adjacent two cross tracks 2 again；Two groups of wheel groups 4 can be set to four, and every two A is one group, and corresponding cross track 2 is set as two, when mobile platform 3 moves on adjacent two long rails 1, four A wheel group 4 is by two one column, and each column is respectively corresponded walks in a long rails 1, when mobile platform 3 is in two cross tracks 2 When upper mobile, four wheel groups 4 press two a line, and every row is respectively corresponded walks in a cross track 2；The wheel group 4 can be with Six are set as, corresponding cross track 2 is set as three, when mobile platform 3 moves on adjacent two long rails 1, Six wheel groups 4 are by three one column, and each column is respectively corresponded walks in a long rails 1, when mobile platform 3 is in three cross tracks When moving on 2, six wheel groups 4 press two a line, and every row is respectively corresponded walks in a cross track 2.

Weeder is arranged on the mobile platform 3 so as to farmland weeding, weeding coverage area is just at adjacent Between two long rails 1, the weeder can be existing weeder, and specific structure does not repeat herein.

The mobile platform 3 in use, is first moved to the one of adjacent two long rails 1 by above-described embodiment End, is then turned on weeder, indulges when the mobile platform 3 is moved to adjacent two from one end of adjacent two long rails 1 To track 1 the other end when, weeding work is completed in the farmland between this adjacent two long rails 1, weeder can be closed, then Mobile platform 3 is moved to adjacent two long rails 1 and 2 infall of adjacent two cross tracks, telescopic rod 5 is opened and jacks institute Stating mobile platform 3 makes all wheel groups 4 be detached from long rails 1, then rotate all wheel groups 4 make the rotating direction of all wheel groups 4 with Cross track 2 is consistent, then shrinks telescopic rod 5 and wheel group 4 is allowed to contact with cross track 2, then allow 3 cross running of mobile platform extremely On the adjacent long rails 1 of two other, continuing starting telescopic rod 5 and jacking the mobile platform 3 makes all wheel groups 4 be detached from longitudinal direction Track 1, it is consistent then to rotate long rails 1 that all wheel groups 4 keep the rotating direction of all wheel groups 4 adjacent with two other, connects Shrink the long rails 1 that make wheel group 4 adjacent with two other of telescopic rod 5 and contact, so far, the mobile platform 3 completes change rail Process, and weeder is opened to the farmland weeding between the adjacent long rails 1 of two other.In order to reduce mobile platform 3 Moving distance, cross track 2 are generally located on one end of long rails 1.In above-described embodiment, since farmland is by a plurality of longitudinal rail Road 1 is divided into the muti-piece field being arranged successively, weeding of the mobile platform 3 between adjacent two long rails 1, and weeding area coverage is rigid Good linking, without overlapped part, also exhaustive part, fully achieves accurate farmland weeding, while adjacent two long rails 1 Spacing it is wider, the range of a weeding is larger, also improve in this way weeding work efficiency.

In another technical solution, 3 bottom surface of mobile platform be connected with vertical plane be in inverted T-shape two suspensions 6, two The horizontal component of suspension 6 is arranged in parallel in adjacent two long rails, 1 top respectively, and two groups of wheel groups 4 are rotatably set to respectively Two suspensions, 6 lower section, further raises mobile platform 3, it is ensured that mobile platform 3 will not be stopped along the smooth advance of track by weeds.

In another technical solution, each of two groups of wheel groups 4 wheel group 4 includes the groove body 7 of back-off, is set to groove body Rotating direction and consistent two idler wheel 8 of 7 length direction of groove body in 7 refer to that the direction of travel of idler wheel 8 and the groove body 7 are long Degree direction is consistent, and 7 end face center of groove body offers a first through hole, and the horizontal component of the suspension 6 is strip plate Body, the lower surface of 6 horizontal component of suspension are provided with vertical connecting shaft, and the lower end of the connecting shaft is by being arranged described Bearing and the groove body 7 in first through hole are rotatablely connected.Setting 4 structure of wheel group in this way is simple, when along the track travel Since there are two idler wheels 8 to position simultaneously, deflection is less likely to occur track route, and simultaneous wheels group 4 is realized by bearing flexibly to be turned To.

In another technical solution, two groups of wheel groups 4 are set as four wheel groups 4 altogether, and every two is set to together in four wheel groups 4 One suspension, 6 lower section, the connecting shaft of four wheel groups 4 surround rectangle, the center of the rectangle and the mobile platform 3 in the horizontal plane Center of gravity be overlapped, when rotating direction track 1 along longitudinal direction of four wheel groups 4, it is vertical along adjacent two respectively that four wheel groups 4 line up two column It is mobile to track 1, when transversely track 2, four wheel groups 4 line up two rows respectively along adjacent two for the rotating directions of four wheel groups 4 Cross track 2 is mobile, and the center of gravity of such mobile platform 3 is firm, and moving process is not easy to topple over, while rigid using four wheel groups 4 It is able to satisfy mobile platform 3 well not only in the requirement that long rails 1 are mobile but also move on cross track 2, uses six or more wheel groups 4 Manufacturing cost can then be improved.

In another technical solution, two idler wheels 8 of each wheel group 4 are symmetrically disposed on the connecting shaft two sides, the company Spindle is hollow cylinder, and the centre bore of the connecting shaft is through to the upper surface of 6 horizontal component of suspension, and the movement is flat The second through-hole is offered at connecting shaft center hole described in 3 face of platform, the telescopic rod 5 is passed through from second through-hole and face One long rails 1.It can ensure that the end elongation of telescopic rod 5 enough can just be against raceway surface in this way, support is more firm, if stretching The setting of contracting bar 5 is possible to probe into farmland after 3 other parts of mobile platform, the end elongation of telescopic rod 5, farmland soil property pine It is soft to be easy to cause the unsteady problem of support.

In another technical solution, the telescopic rod 5 be cylinder perhaps oil cylinder because cylinder or oil cylinder are from a wealth of sources, It is easy to use.

In another technical solution, multiple support rods are provided on the mobile platform 3, multiple support rods support jointly The ceiling of the one covering mobile platform 3, peasant household can operate on mobile platform 3 control the opening or closing of weeder, Telescopic rod elongates or shortens, and is avoided that peasant household works under burning sun in this way, improves working environment.
