Abstract
The invention discloses a locking device of an unloading hopper of a mixer car and the mixer car with the locking device. The locking device includes a locking device housing with one end fixedly connected to a dead plate, a locking member rotationally jointed to an open end of the locking device housing, an elastic component with one end fixed to the inner side of the locking device housing and the other end connected to the locking member, and a handle fixed on or integrally molded with the locking member. The locking member is L-shaped or hook-shaped, has a buckling part arranged outside the locking device housing for locking the unloading hopper. According to the invention, the locking device has a simple structure that the unloading hopper is able to be locked or released through turning the locking member by the handle. The locking device is easy to operate and can be used in locking various unloading hoppers of mixed cars.
Description
Technical field
The present invention relates to trucd mixer, especially trucd mixer discharge bucket locking device and there is the trucd mixer of locking device.
Background technology
Trucd mixer discharge bucket is generally provided with the locking device be made up of retaining mechanism and unlock switch.Existing locking device comprises latch, lock, fork lock etc., its unlock switch and and retaining mechanism be all placed in a housing.But in some cases, if the locking of device trucd mixer discharge bucket, just cannot meet relevant user demand.
Summary of the invention
Goal of the invention: the trucd mixer discharge bucket locking device that the present invention will provide a kind of structure simple, easy to operate, to solve the problem.
Technical scheme: a kind of trucd mixer discharge bucket locking device, comprise one end to be fixedly connected the locking device housing on fixed head, rotatably be connected in the locking member of described locking device housing open end, one end is fixed on described locking device case inside, the other end is connected in flexible member on locking member, and is fixed on locking member or handle integrated with locking member; Described locking member becomes L shape or hook-type, has one for locking the buckling parts be positioned at outside locking device housing of discharge bucket.
Described flexible member is extension spring.Described buckling parts is arc.
A kind of trucd mixer with above-mentioned trucd mixer discharge bucket locking device.
Beneficial effect: structure of the present invention is simple, by handle rotation lock gripping members to lock or to unclamp discharge bucket, operation is very easy, and the present invention can be used for locking various types of trucd mixer discharge bucket.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
As shown in Figure 1, the locking device of trucd mixer discharge bucket of the present invention comprises one end and to be fixedly connected the locking device housing 2 on fixed head 1, rotatably be connected in the locking member 6 of locking device housing 2 open end, one end is fixed on inside locking device housing 2, the other end is connected in extension spring 7 on locking member 6, and is fixed on locking member 6 or handle integrated with locking member.Locking member 6 one-tenth L shape or hook-type, it is rotatably connected on locking device housing 6 by bearing pin and latch, be positioned at the connection part 62 being positioned at the arc buckling parts 61 outside locking device housing and connecting with extension spring be respectively for locking discharge bucket at pin joint point two ends, wherein the end of arc buckling parts is provided with stopper protrusion, to lock discharge bucket.Particularly, locking device housing is removably fixed on fixed head 1 by bolt 3 and nut 4.
Above-mentioned locking device is arranged on trucd mixer in an appropriate manner, trucd mixer of the present invention can be obtained.
In use, rotary handle, is pushed into certain position by discharge bucket, release handle, and locking member rotates under the effect of extension spring, locking discharge bucket.Under the buckling parts of arc and the effect of stopper protrusion thereof, discharge bucket can be effectively locked.When needs put down discharge bucket, same rotary handle can realize.If the firmness of locking is inadequate, extension spring or locking member can be changed.
