Abstract
Disk harrow protective device, belongs to agricultural mechanical field.Existing disk easily weares and teares.The utility model comprises multiple blade, two supports, rotating shaft, two eccentric wheels and eccentric wheel driving mechanisms, described blade is installed on rotating shaft by bearings, rotating shaft terminal is threaded onto on two supports by described eccentric wheel, and one of them eccentric wheel is connected with eccentric wheel driving mechanism.The utility model drives rotating shaft to move up and down by eccentric wheel driving mechanism, thus disk harrow can be made can to rotate up and down when not working, and prevents from causing damage with ground friction, also convenient transport.
Description
Technical field
The utility model belongs to agricultural mechanical field, especially relevant with disk harrow protective device.
Background technology
Disk harrow be according to the principle of rake farming with concave disk in groups for workpiece, blade cutting edge plane is vertical and have an adjustable drift angle with unit direction of advance with ground.During operation, under tractor drawbar pull and soil reaction force acts, blade rolling is advanced, and in blade cutting edge incision soil, cuts off grass roots and crop cover, and makes earth overturn whereabouts after blade concave surface rising certain altitude.Existing disk is substantially parallel with ground when not working, and than being easier to and ground friction and cause damaging, and easily causing damage to disk at transporting disc rake, indirectly reducing the efficiency that disk is raked the soil level.
Utility model content
The purpose of this utility model is intended to overcome existing disk and easily weares and teares, and provides a kind of disk harrow protective device.
For this reason; the utility model is by the following technical solutions: disk harrow protective device; comprise multiple blade; it is characterized in that; described disk harrow protective device also comprises two supports, rotating shaft, two eccentric wheels and eccentric wheel driving mechanism; described blade is installed on rotating shaft by bearings, and rotating shaft terminal is threaded onto on two supports by described eccentric wheel, and one of them eccentric wheel is connected with eccentric wheel driving mechanism.
As to technique scheme supplement and perfect, the utility model also comprises following technical characteristic.
Two described supports are parallel to each other.
Described eccentric wheel driving mechanism is servomotor.
Use the utility model can reach following beneficial effect: the utility model drives rotating shaft to move up and down by eccentric wheel driving mechanism, thus disk harrow can be made can to rotate up and down when not working, and prevents from causing damage with ground friction, also convenient transport.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the cross-sectional view along A-A line in Fig. 1.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail.
As shown in Figure 1, the utility model comprises multiple blade 2, two supports 3, rotating shaft 1, two eccentric wheels 5 and eccentric wheel driving mechanism 4, described blade 2 is installed on rotating shaft 1 by bearings, rotating shaft 1 two ends are threaded onto on two supports 3 by described eccentric wheel 5, one of them eccentric wheel 5 is connected with eccentric wheel driving mechanism 4, and two supports 3 are parallel to each other.
As preferably, eccentric wheel driving mechanism 4 is servomotor.
More than show and describe general principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
