Description
Technical field
The utility model relates to the mower technical field, particularly relates to a kind of mowing and meadow trimming device.
Background technology
Because the meadow of urban afforestation band, golf course, farm and garden etc. often needs regularly to prune; To keep the attractive in appearance of meadow integral body and to satisfy the needs on athletic ground; And this operation is a suitable onerous toil; The scheme of therefore existing several work machinery, and oneself is through being applied.In these Work machines, because therefore small-sized the and easy operation of mower is widely used.Common mower is through with turning cylinder in the action bars of tubulose, through the prime mover that is located at the action bars rear end turning cylinder is rotated, thereby make the blade rotation that is located at the action bars front end.The operator bobs and weaves through gripping the operating grip that is located at the action bars stage casing, utilizes blade to cut the grass on a lawn with this.
The structure of existing mower has nothing in common with each other, and some mower adopts single blade, can only cut cursive script through high speed rotating, can't repair the edge on lawn; Some mower has adopted double blade, but when chaffcutter or finishing edge, meadow, exists efficient lower, rocks and defectives such as noise is bigger, causes use convenient inadequately.
Summary of the invention
The utility model technical problem to be solved provides a kind of mowing and meadow trimming device, realizes to cursive script or edge, meadow steadily, shear efficiently.
The utility model solves the technical scheme that its technical problem adopted: a kind of mowing and meadow trimming device are provided; Comprise gear-box, the upper cutter head of cutter is installed and the following tool rest of bottom knife is installed; Said upper cutter head is symmetrical up and down with following tool rest; The circumferential position of said upper cutter head connects with hollow splined shaft, and said upper cutter head inboard is provided with bearing; Said tool rest down connects with rotating shaft; Said rotating shaft passes said bearing and hollow splined shaft successively and links to each other with a gear in the gear-box, and said hollow splined shaft links to each other with another gear in the gear-box, and the direction of rotation of said hollow splined shaft and rotating shaft is opposite.
The locking screw cover locking is passed through on upper cutter head in the outer ring of said bearing.
Said bearing is a ball bearing.
The circumferential position of said upper cutter head and hollow splined shaft splined.
Said tool rest and rotating shaft splined down.
Said cutter is installed on the upper cutter head through sunk screw.
Said bottom knife is installed in down on the tool rest through sunk screw.
Beneficial effect
Owing to adopted above-mentioned technical scheme, the utility model compared with prior art has following advantage and good effect: the utility model is through the reverse rotation between cutter and the bottom knife, to realize to cursive script or edge, meadow steadily, shear efficiently.Utilize the inner ring of bearing to be enclosed within on the rotating shaft, the outer ring is fixed on the upper cutter head, has increased by two tool rest centering rigidity; Rotating shaft and hollow splined shaft can transmit bigger torque with following tool rest and upper cutter head splined respectively; Blade meets with obstruction and also is not easy to take place to connect situation about losing efficacy between tool rest and the axle when running up, tool rest and spool between relatively good to neutrality, high speed rotating does not have and rocks; Noise is little, and cutting efficiency is high.Cutter and bottom knife all are fixed on the tool rest separately through sunk screw and are easy to dismounting, and be necessary for frequent needs are followed the cutting machine of tool changing sheet.
Description of drawings
Fig. 1 is the assembly drawing of the utility model;
Fig. 2 is the cutaway view of the utility model;
Fig. 3 is the partial enlarged drawing of A among Fig. 2.
Embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment only to be used to the utility model is described and be not used in the restriction the utility model scope.Should be understood that in addition those skilled in the art can do various changes or modification to the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
The embodiment of the utility model relates to a kind of mowing and meadow trimming device; Like Fig. 1, Fig. 2 and shown in Figure 3; Comprise gear-box 1, the upper cutter head 3 of cutter 2 is installed and the following tool rest 5 of bottom knife 4 is installed; Said upper cutter head 3 is symmetrical about in the of 5 with following tool rest, and wherein cutter 2 all can be installed on the tool rest separately through sunk screw with bottom knife 4.The circumferential position of said upper cutter head 3 connects with hollow splined shaft 6, and connecting mode can adopt splined.Said upper cutter head 3 inboards are provided with bearing 8, and the outer ring of bearing 8 can be overlapped 9 through locking screw and be locked on the upper cutter head 3; Said tool rest 5 down connects with rotating shaft 7, and connecting mode can adopt splined; Said rotating shaft 7 passes said bearing 8 successively and links to each other with gear-box 1 an interior gear with hollow splined shaft 6; Said hollow splined shaft 6 links to each other with gear-box 1 another interior gear; Said hollow splined shaft 6 is opposite with the direction of rotation of rotating shaft 7, thereby can make the direction of rotation of cutter 2 and bottom knife 4 opposite.Wherein, bearing 8 can be ball bearing.
Be not difficult to find that the utility model is through the reverse rotation between cutter and the bottom knife, to realize steadily, shear efficiently to cursive script or edge, meadow.Utilize the inner ring of bearing to be enclosed within on the rotating shaft, the outer ring is fixed on the upper cutter head, has increased by two tool rest centering rigidity; Rotating shaft and hollow splined shaft can transmit bigger torque with following tool rest and upper cutter head splined respectively; Blade meets with obstruction and also is not easy to take place to connect situation about losing efficacy between tool rest and the axle when running up, tool rest and spool between relatively good to neutrality, high speed rotating does not have and rocks; Noise is little, and cutting efficiency is high.Cutter and bottom knife all are fixed on the tool rest separately through sunk screw and are easy to dismounting, and be necessary for frequent needs are followed the cutting machine of tool changing sheet.
In sum, the utility model when running cutter and bottom knife be with opposite direction rotation, and the formation shear effect can cut the grass on a lawn and can cut the edge, meadow, even under lower rotating speed, also can mow.The mower of the single blade that could mow with the high rotating speed of needs is compared, and has higher cutting efficiency and better cutting effect and the function at the edge, finishing meadow that do not have; Compare with common double blade device, have higher cutting efficiency and more stable cutting performance.Tool rest and jackshaft relatively good to neutrality steadily do not have during high speed rotating and rocks.Scissor shearing does not simultaneously produce big impulsive force, has avoided that the vegetation root sustains damage in pruning, cuts hard thing (like stone) and can not splash everywhere yet, uses safer.This structure also is easy to dismounting in addition, and daily replacing blade is more convenient.
