Detailed Description

The present application is described in further detail below with reference to figures 1-6.

The embodiment of the application discloses garrulous grass machine.

Example 1

Referring to fig. 1 and 2, a grass chopper, including the grass chopper main part and install the lift adjustment mechanism who is used for adjusting the grass chopper main part near the front end in the grass chopper main part, the grass chopper main part includes fuselage 1 and installs the cutting mechanism on fuselage 1, fuselage 1 includes housing 11 and two rear wheels 14 of roll installation, housing 11 is inside hollow and bottom and front and back end are uncovered, cutting mechanism includes installation axle 2, install a plurality of cutters 3 and the power part on installation axle 2, installation axle 2 horizontal installation is in housing 11 and can rotate, installation axle 2 is perpendicular to the direction of travel setting of fuselage 1. The power part is installed on fuselage 1, and the power part can be the motor for the rotation of drive installation axle 2. The installation axle 2 is fixed with the multiunit mounting panel along the axial, and two mounting panels that are parallel to each other are a set of, wear to establish a bolt between a set of mounting panel, and the bolt sets up for installation cutter 3 in a parallel with installation axle 2.

Cutter 3 includes polylith blade 31, and polylith blade 31 rotates and installs on the bolt between a set of mounting panel to when power component drove installation axle 2 and rotates, installation axle 2 can drive cutter 3 and rotate, realizes the garrulous grass function. One cutter 3 comprises three blades 31, the middle blade 31 is a rectangular plane piece, and the other two blades 31 are bent towards the direction deviating from each other, so that weeds in different directions can be cut, and the grass chopping efficiency is improved. In this process, since the blade 31 rotates in a vertical plane, the possibility that the blade 31 is wound to affect the work when cutting weeds can be reduced.

Install the lift adjustment mechanism who is used for adjusting cutting mechanism height on the fuselage 1, lift adjustment mechanism includes articulated mast 4, handle 5 and two parallel arrangement's stabilizer blade 6, and articulated mast 4 level setting and both ends are rotated and are connected on 11 roof of housing for articulated mast 4 can rotate. Handle 5 welds perpendicularly on hinge bar 4, and handle 5 keeps away from hinge bar 4 one end and extends to the afterbody of fuselage 1 to user's accessible handle 5 rotates hinge bar 4. Stabilizer blade 6 is the L form, and 6 one end of stabilizer blade and hinge bar 4 keep away from 5 one side vertical welds of handle, and the other end is vertical setting down and highly is higher than housing 11 for housing 11 can be unsettled. Front wheel 7 is installed to the vertical one end bottom of stabilizer blade 6, and front wheel 7 is the auto-lock universal wheel for when fuselage 1 traveles, front wheel 7 and ground contact and roll, reduce the resistance on ground.

When the height of the housing 11 needs to be increased, the handle 5 can be lifted upwards, the handle 5 vertically moves upwards, and the housing 11 is driven to vertically move upwards, so that the height of the cutter 3 is increased, at the moment, the front wheel 7 and the rear wheel 14 land, the distance between the front wheel 7 and the rear wheel 14 is shortened, and the front wheel 7, the hinge rod 4 and the rear wheel 14 form an inverted V shape with the hinge rod 4 as the highest point. When the cover 11 needs to be reset, the handle 5 can be released, so that the hinged rod 4 and the cover 11 move downwards under the action of gravity, and the cover 11 falls back, thereby lowering the height of the cutting mechanism. Not only can adjust the height of the grass piles left during cutting grass, but also can cut grass with different heights.

Referring to fig. 1 and 3, a bolt 51 is rotatably connected to an end of the handle 5 away from the hinge rod 4, one end of the bolt 51 is bent to be circular and sleeved on the handle 5, and the inner diameter of the circular ring is slightly larger than the diameter of the handle 5, so that the bolt 51 can rotate and move along the handle 5. The end of the bolt 51 far away from the handle 5 is arranged in a straight line, and the end part is gradually reduced and tapered. The fuselage 1 is provided with a plurality of pinholes 12, and the aperture of pinhole 12 is kept away from handle 5 one end looks adaptation with bolt 51 for bolt 51 can insert pinhole 12, and when needing short-term the fixing after handle 5 rotates to suitable height, can insert bolt 51 in pinhole 12, with handle 5 lock solid can. Perpendicular welding has the grass pressing pole 8 of level setting between two 6 vertical sections of stabilizer blade, can be when fuselage 1 traveles, and higher grass is pressed down earlier for cutter 3 can contact the root of grass and cut.

Referring to fig. 2 and 4, the open front end and the open rear end of the machine body 1 are respectively provided with the check curtains 9, and the check curtains 9 and the cover 11 enclose the cutters 3, so that the possibility of splashing sundries generated during cutting is reduced. The stop curtain 9 includes horizontal pole 91 and polylith baffle 92, and horizontal pole 91 is the inner wall that shell 11 was fixed at round bar and both ends, and baffle 92 sets up the round hole that runs through for rectangular plate and one end, and horizontal pole 91 is worn to establish in the round hole for baffle 92 can rotate relative horizontal pole 91, reduces baffle 92 and runs into the possibility that the barrier influences fuselage 1 and traveles.

The implementation principle of a garrulous grass machine of this application embodiment does: when needing to weed, can promote fuselage 1 and go forward, simultaneously, the power part drives installation axle 2 and rotates, and installation axle 2 drives blade 31 and rotates around installation axle 2, cuts the not equidirectional weeds, because blade 31 rotates at vertical plane, when can reduce the cutting weeds, blade 31 is twined the possibility of influence work.

Example 2

Referring to fig. 5 and 6, a grass chopper, the difference with embodiment 1 lies in, the lift adjustment mechanism includes two lifter 10 that set up respectively in fuselage 1 front end both sides, lifter 10 is the rectangular plate, fuselage 1 front end both sides welded fastening respectively have spout 13, spout 13 encloses into the rectangle passageway that supplies lifter 10 to pass with the lateral wall of housing 11, lifter 10 wears to establish in spout 13 and fixes with spout 13 through the bolt, front wheel 7 is installed in the bottom of lifter 10, the lowest of front wheel 7 is less than the lowest of housing 11 for front wheel 7 plays the effect of supporting housing 11. A plurality of through-holes 101 have been seted up along the direction of height to lifter 10, during the use, lift the relative lifter 10 upward movement of housing 11 for housing 11 risees for lifter 10, thereby drives cutter 3 and risees, and is fixed through the different through-holes 101 with bolt and lifter 10, thereby adjusts the height of housing 11 front end, realizes adjusting cutter 3's height, thereby the grass pile height that leaves when adjusting the garrulous grass and the not grass of cutting co-altitude.
