Abstract
The utility model discloses an independent opening mechanism for a tank bin door of a bulk feed truck. The technical scheme of the independent opening mechanism for the tank bin door of the bulk feed truck comprises a discharging door panel which is arranged inside a bin chamber and a rocking bar mechanism. The rocking bar mechanism and a fixed shaft form an included angle and are fixed connected with each other to form a leverage mechanism. One end of the rocking bar is connected with a telescopic shaft in a hinge pin mode, and the other end of the rocking bar is connected with the discharging door panel in a hinge pin mode. The independent opening mechanism for the tank bin door of the bulk feed truck is simple in structure and each opening mechanism of the bin chamber is independent. Compared with the prior art, the independent opening mechanism for the tank bin door of the bulk feed truck can not limit the length of the tank and the division of the bin chamber and is convenient to maintain. In addition, each bin chamber can be opened easily, so technology progress is reflected.
Description
Technical field
The utility model relates to a kind of tank car of shipping bulk feed, relates generally to specifically the design of this tank car tank body door mechanism.
Background technology
Known, in order to be applicable to the shipping bulk feed, usually adopt a kind of transportation tank car, tank body is full closeding state, tank body is long and be divided into a plurality of bins usually.For blowing, each bin is equipped with door, be a kind of four storehouse tank bodies as shown in Figure 1, 2, the rotary handle of door-opening mechanism 101 is arranged in the tank body tail end, and bin is a solid shafting foremost, other bin is the hollow central siphon that caliber increases gradually, solid shafting with are connected that a hollow shaft is set on together successively and are connected with the rotary handle of door-opening mechanism 101, need to open where fan door, just rotate corresponding handle, corresponding axle or pipe racks shake arm 3 and rotate, thereby open blowing door-plate 4.
The defective of prior art is, because door-opening mechanism is sleeve structure, if increase bin, door-opening mechanism will be huger, and axle and pipe easily interfere between the tube and tube and kill; Secondly, maintenance difficult need to all be extracted whole piece mechanism out just and can fix a breakdown; The 3rd, the door resistance that is in front end is larger, opens more difficult.So in the practice process, tank body only can arrange four storehouses at present, has greatly limited the increase of length of tank and the possibility of Further Division bin.
So those skilled in the art are necessary the door mechanism of the tank body of this bulk feed vehicle is further improved.
Summary of the invention
For the defective of above-mentioned prior art and the technical problem of existence, the technical problems to be solved in the utility model has provided between a kind of each door, and the mechanism of its switch door is door opening mechanism fully independently mutually.
The utility model solves the problems of the technologies described above the technical scheme that adopts: the independent opening mechanism that is used for bulk feed vehicle tank door, comprise the blowing door-plate that is arranged in bin inside, endplay device, described endplay device becomes angle to be fixedly connected with formation one leverage with fixed axis, the one end is connected with the telescopic shaft bearing pin, and the other end is connected with described blowing door-plate bearing pin.
Technique effect of the present utility model is: the prior art of comparing, the door-opening mechanism of present design arranges separately, separate with the door-opening mechanism of other door, increasing or reduce bin can not affect the structure of door-opening mechanism, so no matter length of tank increases and decreases, bin is divided all without any restriction; Secondly, the design is easy to maintenance, does not involve other bin during certain bin door-opening mechanism maintenance; The 3rd, difficulty is not opened in the unlatching of each bin because the position is different.To sum up solve the defective that prior art exists, embodied technological progress.
Preferred technical scheme: be used for the independent opening mechanism of bulk feed vehicle tank door, described endplay device comprises intermediate rocker and balanced its left and right side rocking bar that is arranged in that is fixed on the fixed axis centre position; The circumferential permanent position of described intermediate rocker and the circumferential fixed bit of described side rocking bar are set to default angle.
Further technique effect: the leverage that at first is made of three rocking bars is easy to open door; Secondly, the equilibrium of three rocking bars arranges, stressedly when being conducive to door and opening or close evenly more easily opens/close, and also is conducive to protect the intensity of member; The 3rd, become the lever of angle to be conducive to save mechanism's stroke.
Preferred technical scheme: be used for the independent opening mechanism of bulk feed vehicle tank door, described telescopic shaft comprises a leading screw, has the sleeve of internal thread, the leading screw protective sleeve; Described sleeve one end is connected with the intermediate rocker bearing pin, and the other end cooperates with leading screw in being contained in described leading screw protective sleeve; The described bin outside is equiped with the rotary handle that is fixedly connected with leading screw.
Further technique effect: only need turn handle control telescopic shaft elastic; can change the rocking arm position, thereby mention or put down the blowing door-plate, realize opening or closing of door; secondly the effect of protective sleeve is that the protection telescopic shaft is working properly, and the not lubricated oil of feed (fat) pollutes.

The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is elaborated, further illustrate advantage of the present utility model and with respect to the outstanding contributions of prior art, understandable, following embodiment only is the detailed description to the better embodiment of the utility model, should not be construed as any restriction to technical solutions of the utility model.
As shown in Figure 3, the design mainly comprises bin 1, endplay device, telescopic shaft 5, fixed axis 6, blowing door-plate 4 etc.
In bin 1 inside, to cut off base plate and be provided with bearing support, fixed axis 6 rotatable support are therein.Intermediate rocker 3a is welded on the center of fixed axis 6 and is connected with sleeve 52 bearing pins by connector; At the balanced weld side rocking bar of the left and right side of intermediate rocker 3a 3b, 3c, and link together by connector and blowing door-plate 4 bearing pins.The circumferential welding position of intermediate rocker 3a and side rocking bar 3b, the circumferential welding position of 3c form an angle, and more laborsaving when this is conducive to pull-up blowing door-plate 4, mechanism's rotational travel is shorter.
Sleeve 52 has internal thread and cooperates with leading screw 51; for the smooth and easy engagement between protection sleeve 52 and the leading screw 51 and feed are not polluted by the lubricant grease of leading screw 51; leading screw 51 is housed inside leading screw protective sleeve 55 inside that are fixed on the holder 54, and leading screw 51 other ends are fixedly connected with rotary handle 53 outside the storehouse.
Shown in Fig. 4,5; when needs are opened door; turn rotary handle 53; sleeve 52 and the past leading screw protective sleeve 55 inner indentations of leading screw 51 engagements; intermediate rocker 3a drives fixed axis 6 rotations; side rocking bar 3b, 3c are upturned with fixed axis 6 rotational angles and spur the 4 upwards liftings of blowing door-plate, thereby open door, and feed skids off bin 1 from blowing door-plate 4 sides.When closing, reverse turn rotary handle 53, sleeve 52 stretches out outside leading screw protective sleeve 55 inside are outside, and side rocking bar 3b, 3c rotate angle, put down blowing door-plate 4, close door.
The utility model is simple in structure, and each bin door-opening mechanism is independent, can not limit compared to existing technology the length of tank body and the division of bin, and easy to maintenance, and each bin is opened easily, has embodied technological progress.
