Abstract
The invention discloses a dozer blade, and in particular to a stable dozer blade. According to the stable dozer blade, a bolt assembly for connection is arranged between a fork and a shovel blade. The bolt assembly comprises a bolt and a nut. The bolt comprises a bolt head and a threaded rod. The nut is provided with an extension plate. The fork is provided with a rabbet matched with the extension plate in shape. Two corner rods made of spring steels are connected to one side face of the extension plate. The corner rods comprise first supporting rods and second supporting rods which are fixed to the extension plate. One ends of the first supporting rods and the second supporting rods are connected, and threaded holes in threaded connection with the threaded rod are formed in the other ends of the first supporting rods. The threaded rod is in threaded connection with the threaded holes of the first supporting rods. The threaded holes of the first supporting rods are in threaded connection, and one ends of the first supporting rods abut against the lower end of the fork. The technical defect that in the prior art, a fork is prone to disengaging from a shovel blade is overcome, and by means of the stable dozer blade, the fork can be prevented from disengaging from the shovel blade.
Description
Technical field
The present invention relates to a kind of dozer, especially relate to a kind of stable type dozer.
Background technology
Small four-wheel tractor is many in rural area use, and thing of generally hauling goods, the things such as to plow are many.Sometimes baby tractor is used for wholely, the things such as snow pushing.At present, market also there is not the baby tractor being with dozer.
In order to solve the problems of the technologies described above, Chinese patent CN203160295U provides a kind of stable type dozer, be made up of perching knife, fixed mount, oil pump, fork, described perching knife rear wall is provided with fixed mount, fixed mount and the lifting chute being contained in tractor preposition cooperatively interact, fixed mount lower end is connected with oil pump pull bar, and fork is fixed by bolts to the front lower end of perching knife.
But still there is following technological deficiency in above-mentioned prior art.
Adopt bolt to be connected with perching knife by fork, but bolt belongs to and is subject to mechanical oscillation impact and loosening connector occurs, normal phase use, described fork easily comes off from perching knife.
Summary of the invention
The invention is intended to provide a kind of stable type dozer, come off from perching knife to avoid fork
Stable type dozer in this programme, comprises perching knife, fixed mount, oil pump and fork, and described fixed mount is connected on the rear wall of perching knife, and fixed mount lower end is connected with the pull bar of oil pump, is provided with the bolt assembly be connected between fork with perching knife; Described bolt assembly comprises bolts and nuts, and wherein bolt comprises bolt head and screw rod, and fork and perching knife are provided with the installing hole passed through for screw rod; Described nut is provided with extended plate, described fork is provided with the tongue and groove with described extended plate form fit, one side of described extended plate is connected with the angle pole that two spring steel are made, described angle pole comprises the first pole and is fixed on the second pole in extended plate, one end of first pole is connected with the second pole, the other end of the first pole is provided with the screwed hole be connected with described screw flight, described screw rod is threaded with the screwed hole of each first pole, and one end of described first pole and the installing hole of described fork offset.
Adopt technical scheme of the present invention, there is following technique effect:
Described fork is located by extended plate and the first pole swelling, and the first pole is connected with screw rod, and perching knife is clamped between bolt head and extended plate, forms stable syndeton; Wherein screw rod is threaded with the first pole, and the first pole forms angle pole, and angle pole is made up of spring steel, and therefore this first pole can produce a kind of elasticity press power to screw rod, stop between screw rod and nut and relative motion occurs, namely realize locking effect.
Further, the other end of described first pole is installed with a flat board, and described screwed hole is located at described flat board place.
Conveniently the screwed hole at the first pole place of different angle pole can be aimed at, and spy is installed with a flat board at the other end of the first pole, and flat board can be superimposed together easily, then could be alignd by screwed hole rapidly.And while screw rod is connected with screwed hole, described first pole also can be disturbed with the second pole receipts gradually, cause one end of described first pole gradually near the lower end of fork, finally realize against clamping.
Further, a side of described extended plate is also provided with the 3rd angle pole, and three angle pole circumferences are distributed on outside nut.
In order to stress equalization and Stability Analysis of Structures, spy arranges three angle poles, forms upper and lower correspondence and three screwed holes be connected with screw rod.
Further, described dull and stereotyped downside is also provided with the locking nut be connected with screw flight.
In order to reach anti-loosing effect further, a locking nut can also be strengthened, preventing described first pole location unstable.
Accompanying drawing explanation
Fig. 1 is before installing, the structural representation of bolt assembly in embodiment of the present invention stable type dozer.
Fig. 2 is the structural representation of embodiment of the present invention stable type dozer.
Fig. 3 is after installing, the structural representation of bolt assembly in embodiment of the present invention stable type dozer.
Detailed description of the invention
