Abstract
The invention relates to a protective device of a mower. The protective device of the mower comprises a baffle main body (1) arranged at the front end of the cutting system of the mower. The lower end (11) of the baffle main body (1) is provided with the teeth (12) extending downwards, the baffle main body (1) is connected with a sensor (3) and an alarm (4) used for responding the stress situation. The baffle main body (1) can prevent the cut grass residues for splashing everywhere while the mower is used for working, and can effectively obstruct the impact to the users caused by the foreign matter (as stones, branches, etc.) on the lawn due to the action of the mowing blades. The teeth (12) are used for pushing the foreign matters on the lawn away and removing the foreign matters outside the mower from the arc-shaped surfaces at two sides of the baffle main body, so that the cutting system of the mower can be effectively protected, and the alarm (4) gives an alarm for reminding the operators for cleaning the foreign matters while the foreign matter is oversize and exceeds the stress upper limit of the sensor (3).
Description
Technical field
The present invention relates to a kind of mower field, be specifically related to a kind of mower guard.
Background technology
For convenience of pruning lawn efficiently, improve the production efficiency of labourer, reduce the labour intensity of labourer, mower become enter into people's life fast a kind of for cutting the grass on a lawn, the machine tool of vegetation etc., it is made up of weeding disk, engine, road wheel, running gear, mowing blade, handrail, control section, in the prior art, in order to ensure the handling safety of user, a retaining device can be set above cutter head.
In prior art; retaining device is fixed on and cuts on bar; this retaining device plate is a disc-shaped structure; time cutter head rotates; protective plate can prevent weeds from splashing; thus the safety of protection labourer, this structure can meet instructions for use to a certain extent, but; the protective plate of disc-shaped structure can only prevent weeds from splashing; especially, time to foreign matters such as such as stones, without any protection and barrier structure, there is potential safety hazard; in addition; the design of this protective plate is not quite reasonable, and especially discoid design, exists unnecessary waste.
Summary of the invention
The present invention is for a kind of effective blocking foreign body, and structure is simple, the retaining device of energy comprehensive guarantee user personal safety.
A kind of mower guard of the present invention, comprise baffle body 1, described baffle body 1 camber, its upper surface, left side and right side are connected with the housing 2 of mower, described baffle body 1 bottom 11 is provided with the tooth 12 to downward-extension, also comprises sensor 3 and the alarm 4 of its stressing conditions of reaction be connected with described baffle body 1.
Preferably, described sensor 3 is arranged on inside described baffle body 1.
Preferably, the lower surface 11 of described baffle body 1 and mowing blade mounting plane are at grade.
Preferably, described tooth 12 is provided with elevator 13.
Preferably, described baffle body 1 is plastic material.
The baffle body 1 of camber of the present invention can not only prevent cut under careless slag splash everywhere, the foreign matter of effective obstruct under mowing blade effect on lawn is as stone, branches etc. are to the impact of user, and in conjunction with the tooth 12 that bottom 11 is provided with, along with mower is toward front wheel driving, can foreign matter be pushed open toward mower both sides along the camber line face of baffle body 1, effective protection mowing blade, and which is provided with the sensor 3 of reaction stressing conditions, when the foreign matter road wheel that baffle body 1 touches bulk due to resistance excessive can not toward front wheel driving time, the active force that baffle body 1 measured by sensor 3 is greater than in limited time, to the signal of alarm 4 correspondence, alarm 4 sends chimes of doom, user is reminded to remove foreign matter.
Accompanying drawing explanation
Fig. 1 is the structural representation of retaining device of the present invention.
In figure: 1 baffle body, 2 housings, 3 sensors, 4 alarms, 11 lower surfaces, 12 teeth, 13 elevators.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
As shown in Figure 1, a kind of mower guard of the present invention, comprise the baffle body 1 that an arc is arranged, the central axis of the summit of arcwall face and the diced system of mower is positioned on straight line.It is not shown that the upside of baffle body 1, left side and right side extend to mower housing 2() on.The bottom of this baffle body 1 is provided with the tooth 12 be parallel to each other to downward-extension.Baffle body 1 is also provided with interconnective force sensor 3 and alarm 4.During use, mower ground-engaging wheel and mowing system carry out operation, and baffle body 1 can intercept the splashing of the careless slag under being cut and prevent the impact of the foreign matters such as broken finger stone, protection operator.When the tooth 12 of baffle body 1 touches the foreign matter higher than tooth 12 lower surface, under the driving of road wheel, mower promotes foreign matter toward front wheel driving and moves away outside mower along the arcwall face of baffle body 1 both sides, avoids the wearing and tearing of foreign matter to mower diced system.When foreign matter gravity is excessive; when the road wheel of mower cannot be walked forward; the stressing conditions of baffle body 1 measured by sensor 3; when resistance is greater than the value of setting; give alarm 4 one respective signal of being connected with it, alarm 4 sends chimes of doom, and prompting user stops operation removing foreign matter; effectively can protect diced system, extend the service life of mower.
Described sensor 3 is arranged on inside described baffle body 1.Like this, the attractive in appearance of mower entirety is not affected.
The lower surface 11 of described baffle body 1 and mowing blade mounting plane at grade, protect body 1 and mowing system correspondence like this, improve the ability getting rid of foreign matter.
Described tooth 12 is provided with elevator 13, can adjust the concrete, very easy to use of the relative ground of tooth 12 accordingly according to the vegetation height that will cut with the position of diced system.
Described baffle body 1 is plastic material, and cost is low, and plastic material is flexible, easy to use.
The above is the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications are also considered as protection scope of the present invention.
