Description
Technical field
The utility model relates to a kind of dozer, especially relates to a kind of stable type dozer.
Background technology
Small four-wheel tractor is the most in rural area use, and thing of typically hauling goods, the things such as plow are the most.Sometimes baby tractor is used for wholely, the things such as snow pushing.At present, market the most there is not the baby tractor of band dozer.
In order to solve above-mentioned technical problem, Chinese patent CN203160295U provides a kind of stable type dozer, it is made up of perching knife, fixed mount, oil pump, fork, described perching knife rear wall is provided with fixed mount, the fixed mount lifting chute preposition with being contained in tractor cooperates, 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 above-mentioned prior art still suffers from following technological deficiency.
Using bolt to be connected with perching knife by fork, but bolt belongs to the connector easily affected by mechanical oscillation and loosen, the normal phase uses, and described fork easily comes off from perching knife.
Utility model content
The utility model is intended to provide a kind of stable type dozer, to avoid fork to come off from perching knife
Stable type dozer in this programme, including perching knife, fixed mount, oil pump and fork, 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 being connected between fork with perching knife；Described bolt assembly includes bolts and nuts, and wherein bolt includes that bolt head and screw rod, 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 and the tongue and groove of described extended plate form fit, the one side of described extended plate connects the angle pole having two spring steel to make, described angle pole includes the first pole and the second pole being fixed 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 being connected with described screw flight, described screw rod is threadeded with the screwed hole of each first pole, and the installing hole of one end of described first pole and described fork offsets.
Use the technical solution of the utility model, have the following technical effect that
Described fork is positioned 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 attachment structure；Wherein screw rod and the first pole are threaded, and the first pole is to form angle pole with the second pole, and angle pole is made up of spring steel, and therefore this first pole of institute can produce a kind of elastic press power to screw rod, stop and relative motion occurs between screw rod and nut, i.e. 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.
Screwed hole at first pole of different angle poles can be directed at for convenience, and the special other end the first pole is installed with a flat board, 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 gradually can be received with the second pole and be disturbed, and causes one end of described first pole to move closer to the lower end of fork, finally realizes against clamping.
Further, the one side of described extended plate is additionally provided with the 3rd angle pole, and three angle pole circumferences are distributed on outside nut.
For stress equalization and Stability Analysis of Structures, spy arranges three angle poles, forms three screwed holes that are the most corresponding and that be connected with screw rod.
Further, it is additionally provided with, on the downside of described flat board, the locking nut being connected with screw flight.
In order to further up to anti-loosing effect, it is also possible to strengthen a locking nut, prevent described first pole location shakiness.
Accompanying drawing explanation
Before Fig. 1 is for installing, the structural representation of bolt assembly in the utility model embodiment stable type dozer.
Fig. 2 is the structural representation of the utility model embodiment stable type dozer.
After Fig. 3 is for installing, the structural representation of bolt assembly in the utility model embodiment stable type dozer.
Detailed description of the invention
Below by detailed description of the invention, the utility model is described in further detail.
Reference in Figure of description includes: perching knife 1, fixed mount 2, fork the 3, first pole first the 130, first pole second 120, screwed hole second 121, screwed hole first 131, nut 111, extended plate 110, angle pole S, bolt 200.
Embodiment is the most as shown in Figure 2: the present embodiment stable type dozer, and perching knife 1 rear wall is provided with fixed mount 2, and the fixed mount 2 lifting chute preposition with being contained in tractor cooperates, and fixed mount 2 lower end is connected with oil pump pull bar.
Fork 3 is provided with, between lower end front with perching knife 1, the bolt assembly being connected；As shown in Figure 1,3, described bolt assembly includes bolt 200 and nut 111, and wherein bolt includes that bolt head and screw rod, fork and perching knife are provided with the installing hole passed through for screw rod；Described nut is provided with extended plate 110, and described fork is provided with and the tongue and groove of described extended plate form fit, and the one side of described extended plate connects the angle pole S having two spring steel to make.
