Now Highway Construction Machinery medium stone spreader and synchronous chip sealer application is very general, and its medium stone spreading amount is a major parameter of this kind equipment.When the speed of a motor vehicle one timing, material jaw opening and material toggling roller rotating speed are the key factors that affects the rubble spreading amount.
At present, the traditional control system of control material jaw opening size mainly contains following two kinds: a kind of is to adopt rocking bar-sawtooth bin gate detent mechanism, and another kind is the spiral screw rod detent mechanism.This two kinds of detent mechanism apertures precise control, manipulation repeatable accuracy height, but each adjustment is carried out manual operation after all need shutting down, and can't satisfy the demand of automation control.
Summary of the invention
The utility model provides a kind of bin gate stopping means, has mainly solved to carry out manual operation after the each adjustment of existing bin gate stopping means all need be shut down, and can't satisfy the problem of automation demand for control.
Concrete technical solution of the present utility model is as follows:
This bin gate stopping means comprises rotating shaft, bin gate locating oil cylinder and the bin gate cylinder that is arranged on the external side of hopper box, is socketed with bin gate in the rotating shaft; Described bin gate locating oil cylinder one end is connected with the hopper casing, and the other end is connected with rotating shaft, and bin gate cylinder one end is connected with the hopper casing, and the other end is fixedly connected with bin gate; Described rotating shaft one end is provided with angular transducer.
Be provided with on the above-mentioned bin gate for the bin gate anglec of rotation position-limit mechanism.
The above-mentioned bin gate locating oil cylinder other end is connected with the ear seat, and the ear seat is fixedly installed in the rotating shaft.
Above-mentioned bin gate locating oil cylinder one end is connected with the hopper casing by bearing pin, and the bin gate locating oil cylinder is connected by bearing pin with the ear seat, and the bin gate cylinder is connected with the hopper casing by bearing pin.
Above-mentioned rotating shaft is fixed on the external side of hopper box by rolling bearing units.
Above-mentioned angular transducer is fixedly installed on the rotating shaft left end.
Above-mentioned position-limit mechanism is the spacing thick stick of bin gate that is fixedly installed in the rotating shaft.
Above-mentioned hopper casing discharging opening below is provided with the spreading material roller.
The utility model has the advantage of:
This bin gate stopping means adopts hydraulic jack to drive spacing thick stick rotating shaft and rotates to an angle, and adopts angular transducer, realizes the automation control of material jaw opening size; Its compact conformation, conserve space, precise control, it is high to handle repeatable accuracy, can realize automation control.
Description of drawings
Fig. 1 is bin gate stopping means schematic diagram
Fig. 2 is the A-A sectional view of Fig. 1
The accompanying drawing detail is as follows: 1, angular transducer; 2, hopper casing; 3, the spacing thick stick of bin gate; 4, bin gate locating oil cylinder; 5, bin gate cylinder; 6, rolling bearing units; 7, spreading material roller; 8, bin gate locating oil cylinder engaging lug seat; 9, pivot pin; 10, bin gate; 11, rotating shaft.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in detail, as shown in Figure 1:
This bin gate stopping means comprises rotating shaft, bin gate locating oil cylinder and the bin gate cylinder that is arranged on the external side of hopper box, is socketed with bin gate in the rotating shaft; Bin gate locating oil cylinder one end is connected with the hopper casing, and the other end is connected with rotating shaft, and bin gate cylinder one end is connected with the hopper casing, and the other end is fixedly connected with bin gate; Rotating shaft one end is provided with angular transducer, and angular transducer generally is fixedly installed on the rotating shaft left end; Bucket casing discharging opening below is provided with the spreading material roller.Be provided with the position-limit mechanism for the restriction bin gate anglec of rotation on the bin gate, the bin gate locating oil cylinder other end is fixedly connected with rotating shaft by the ear seat, the ear seat is fixedly installed in the rotating shaft, bin gate locating oil cylinder one end is connected with the hopper casing by bearing pin, the bin gate locating oil cylinder other end is connected by bearing pin with the ear seat, and the bin gate cylinder is connected with the hopper casing by bearing pin; Rotating shaft is fixed on the external side of hopper box by rolling bearing units; Position-limit mechanism is generally the spacing thick stick of the bin gate that is arranged in the rotating shaft.
It is specifically: rolling bearing units 6 are installed on the supported on both sides of hopper casing 2 and rotating shaft 11, and rotating shaft 11 can be rotated freely; The spacing thick stick 3 of bin gate and bin gate locating oil cylinder engaging lug seat 8 are fixed in the rotating shaft 11; The piston rod of bin gate locating oil cylinder 4 is connected by pivot pin 9 with locating oil cylinder engaging lug seat 8, and the cylinder body of bin gate locating oil cylinder 4 is connected by pivot pin 9 with hopper casing 2; Bin gate 10 is enclosed within the rotating shaft 11; Angular transducer 1 is installed on the left side of hopper casing 2, and the axle of angular transducer 1 and rotating shaft 11 link together.
