Abstract
The utility model discloses a concrete mixer hopper door opening and closing mechanism. The concrete mixer hopper door opening and closing mechanism comprises a wedge block, a hopper door and a hydraulic ram, wherein the wedge block is fixedly arranged on one side of a bottom opening of a mixer body, a wedge groove which is meshed with the edge of a hopper door is formed in the wedge block, and the hopper door is arranged on the other side of the bottom opening of the mixer body through a third pin column and can rotate around with the third pin column; and one end of the hydraulic ram is arranged on the bottom of the mixer body through a first pin column, and the other end of the hydraulic ram is connected on the hopper door through a second pin column. According to the concrete mixer hopper door opening and closing mechanism, the hydraulic ram is controlled by a hydraulic system so as to adjust the openness of the hopper door, and the hopper door can automatically control when a mixer works and does not need to be adjusted by a specially-assigned person, so that the concrete mixer hopper door opening and closing mechanism is simple in structure, and convenient to operate.
Description
Technical field
The utility model relates to a kind of concrete mixer hopper door open-and-close mechanism, is specifically related to a kind of automatic open-close mechanism that adopts hydraulic jack to control the hopper door folding.
Background technology
Concrete mixer uses on a large scale in building, tunnel, mine support engineering, and when particularly using in mine, normal and concrete pump supports the use.Bottom at mixer is provided with hopper door, concrete finished product after being used for stirring is sent in the hopper of trucd mixer or concrete pump and is carried out pumping, the folding of existing mixer hopper door is substantially all by manually carrying out, owing to often needing to regulate the aperture of hopper door, all need special people to come switch, cause artificial waste.
The utility model content
The technological deficiency of the artificial folding of needs that exists for existing concrete mixer hopper door, the utility model provides a kind of concrete mixer hopper door open-and-close mechanism of controlling automatic open-close by hydraulic jack, and is simple in structure, easy to operate.
The utility model adopts following technical scheme to realize: a kind of concrete mixer hopper door open-and-close mechanism, comprise wedge 1, hopper door 2 and hydraulic jack 3, described wedge 1 is installed in a side of mixer body 7 bottom openings, which is provided with the wedge-shaped slot with hopper door 2 edge interlocks, hopper door 2 by the 3rd pin 6 be arranged on mixer body 7 bottom openings opposite side and can be around the 3rd pin 6 rotations; Described hydraulic jack 3 one ends are arranged on mixer body 7 bottoms by the first pin 4, and the other end is connected on hopper door 2 by the second pin 5.
In the utility model, described hopper door 2 is provided with handle shape projection with the opposite end of wedge 1 interlock and is connected with described hydraulic jack 3.
In the utility model, the rear end of described hydraulic jack 3 and mixer body 7 bottom-hinged, its rod end and hopper door 2 are hinged.
The utility model realizes regulating the aperture of hopper door by the HYDRAULIC CONTROL SYSTEM hydraulic jack, can automatically control when the work of operation mixer, need not the special messenger hopper door is regulated, and it is simple in structure, easy to operate.
Description of drawings
Fig. 1 is the utility model front view.
Fig. 2 is top view of the present utility model.
Number in the figure: the 1-wedge, the 2-hopper door, the 3-hydraulic jack, 4-the first pin, 5-the second pin, 6-the 3rd pin, 7-stirs body.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
Embodiment
referring to Fig. 1 and Fig. 2, concrete mixer hopper door open-and-close mechanism in the present embodiment, it comprises wedge 1, hopper door 2 and hydraulic jack 3, wedge 1 is installed in a side of mixer body 7 bottom openings, which is provided with the wedge-shaped slot with hopper door 2 edge interlocks, hopper door 2 is arranged on the opposite side of mixer body 7 bottom openings and can rotates around the 3rd pin 6 by the 3rd pin 6, hopper door 2 is provided with handle shape projection with the opposite end of wedge 1 interlock, the rear end of hydraulic jack 3 is by hinged mixer body 7 bottoms of being arranged on of the first pin 4, rod end is hinged by the handle shape projection on the second pin 5 hopper doors 2.
When opening hopper door 2, the rod end of hydraulic jack 3 stretches out, and the handle shape projection that promotes on hopper door 2 also prizes hopper door 2 take the 3rd pin 6 as fulcrum, hopper door 2 is broken away from the opening of realizing mixer body 7 bottoms and open blowing from the wedge-shaped slot of wedge 1; When closing hopper door 2, the rod end of hydraulic jack 3 is regained, and pulls the handle shape projection on hopper door 2 that the wedge-shaped slot interlock of hopper door 2 and wedge 1 is realized that it closes.
