Detailed Description

The present invention will be further explained with reference to the drawings and examples.

As shown in fig. 1 to 3, the alpine meadow weeding machine of the present invention comprises a machine body 1 and a weeding device 2, wherein the weeding device 2 comprises a weeding cutter holder 21, a depth adjusting mechanism and a weeding mechanism, and the weeding cutter holder 21 is mounted on the machine body 1; the grass cutting mechanism comprises a lifting platform 22, a grass cutting knife 23 and an impact assembly, wherein the lifting platform 22 is in sliding fit with four guide posts 221 vertically arranged on a grass cutting knife rest 21 so as to be arranged on the grass cutting knife rest 21 in a vertical sliding manner, and the impact assembly is arranged on the lifting platform 22 and connected with the grass cutting knife 23 so as to drive the grass cutting knife 23 to do linear reciprocating motion; the depth adjusting mechanism is connected with the lifting platform 22 so as to adjust the height of the lifting platform 22.

When the grass cutter is used, the height of the lifting platform 22 is adjusted through the depth adjusting mechanism, so that the height of the grass cutter is adjusted, and the grass cutting depth of the grass cutter is adjusted; after the adjustment is finished, the machine body 1 is controlled to advance slowly, the impact assembly drives the weeding cutter 23 to do linear reciprocating motion, so that the weeding cutter 23 is shoveled into the alpine meadow block, and the alpine meadow block is shoveled. Because the grass removing knife 23 does linear reciprocating motion, the grass removing knife 23 does not have vertical motion in the grass removing process, thereby avoiding shaking loose meadow block soil in the grass removing process, solving the problem that the meadow block soil is easy to loose in the grass removing process of the alpine meadow, and thus the meadow block does not need to be manually shoveled, which not only improves the grass removing efficiency of the alpine meadow, but also reduces the transplanting cost of the alpine meadow.

The impact assembly can adopt any mechanism capable of realizing linear reciprocating motion, such as an impact cylinder and the like. The utility model discloses an impact the subassembly and include motor 27, carousel 25, connecting rod 26 and slider 24. The grass cutting knife 23 is connected with the sliding block 24, namely is arranged on the sliding block 24, the sliding block 24 is arranged on the lifting platform 22 and is in linear sliding fit with the lifting platform 22, the motor 27 is arranged on the lifting platform 22 and drives the rotary disk 25 to rotate around the center of the rotary disk, one end of the connecting rod 26 is eccentrically hinged on the rotary disk 25, and the other end of the connecting rod is hinged with the sliding block 24. It is understood that a transmission connection such as a coupling, a reducer, etc. may be provided between the motor 27 and the turntable 25. The linear sliding fit between the slider 24 and the lifting table 22 can be realized by mounting a linear guide rail on the lifting table 22, the linear guide rail being machined from the lifting table 22.

As shown in fig. 1, the depth adjusting mechanism includes a screw 28, a lifting motor 31, and a nut 29 mounted on the mowing tool rest 21 and adapted to the screw 28, one end of the screw 28 passes through the nut 29 and then is in threaded engagement with the lifting table 22 through a second nut 32, and the other end is in transmission connection with the lifting motor 31. Of course, the depth adjusting mechanism can also adopt telescopic mechanisms such as an air cylinder, a hydraulic cylinder and the like, but the structure of the grass mower is too complex and the maintenance is inconvenient. The screw 28 is preferably a trapezoidal self-locking screw, so as to lock the position of the lifting platform 22 conveniently, although the screw 28 may also be a common screw, and in the case of a common screw, it is understood that a transmission connecting member such as a coupling and a speed reducer with a self-locking function may also be arranged between the lifting motor 31 and the screw 28 of the turntable 25, or the lifting motor 31 is a contracting brake motor.

As shown in fig. 4, the grass cutting blade 23 includes a lower blade 231 and side blades 232 respectively fixed on both sides of the lower blade 231, the lower blade 231 is horizontally disposed, the side blades 232 are connected with the sliders 24, and the lower blade 231 and the side blades 232 enclose a grass cutting groove 233 for cutting off the meadow block. The grass cutting trough 233 is set according to the size of the meadow blocks, and generally coincides with the meadow block size. Compare and only be equipped with the grass cutter structure of lower blade 231 alone, the grass cutter that has set up side blade 232 is at the grass cutting in-process, gets into grass cutting groove 233 after the meadow piece is shoveled, and grass cutting groove 233 plays the constraint effect, can further prevent that meadow piece earth from becoming flexible like this. In the figure, the rear end of the weeding trough 233 is provided with a baffle 234 to restrain the shoveled meadow block soil.

In order to facilitate the separation of the shoveled meadow blocks from the weeding knife, the weeding device 2 is further provided with a turnover cylinder 30, the side blade 232 is hinged with the sliding block 24, one end of the turnover cylinder 30 is hinged with the lifting platform 22, and the other end is hinged with the baffle 234. When separating the meadow block, the weeding cutter is lifted through the depth adjusting mechanism, and then the overturning cylinder 30 is controlled to retract, so that the weeding cutter rotates around the hinged point of the weeding cutter (the side blade) and the sliding block 24, the weeding groove 233 inclines downwards, and the meadow block can automatically slide out of the weeding groove under the action of gravity.
