The technical problem to be solved by the utility model is to provide a telescopic unloading hopper whose length can be easily adjusted.

In order to solve the problems of the technologies described above, the technical solution of the utility model is:

A telescopic unloading hopper, including a fixed cylinder and a movable cylinder capable of sliding on the fixed cylinder to change the overall length of the fixed cylinder and the movable cylinder, both of which are connected with a telescopic oil cylinder that drives the movable cylinder to slide relative to the fixed cylinder, The slewing mechanism is rotatably supported on the frame, the fixed cylinder and the slewing mechanism are hinged through the hinge shaft, and the luffing cylinder is set between the fixed cylinder and the slewing mechanism to realize the swing of the fixed cylinder relative to the slewing mechanism around the hinge axis, and the axis of the hinge shaft is perpendicular to the luffing cylinder .

In the above-mentioned telescopic unloading hopper, the rotary position of the rotary mechanism relative to the frame is locked by the locking mechanism.

In the telescopic unloading hopper, the tail end of the telescopic oil cylinder is connected to the support fixed on the fixed cylinder, and the piston rod head of the telescopic oil cylinder is connected to the support fixed on the moving cylinder.

For the above-mentioned telescopic unloading hopper, the rotary mechanism includes a rotary shaft, the fixed cylinder is hinged to the upper end of the rotary shaft, the cylinder body of the luffing cylinder is hinged to the lower end of the rotary shaft, and the head of the piston rod of the luffing cylinder is connected to the support fixed on the fixed cylinder. hinged.

For the above-mentioned telescopic unloading hopper, the fixed cylinder is provided with a chute or a slide rail for the sliding guide of the movable cylinder, and correspondingly, a slide rail or a slide groove is provided on the movable cylinder.

The beneficial effects of the utility model are:

1. Easy installation, hydraulic control, flexible operation, no mechanical impact;

2. The utility model completely solves the problem of manually installing the extension joint, and compensates for the position of the flow material affected by the long or short unloading hopper during the construction process.

Description of drawings

Below in conjunction with accompanying drawing, the utility model is described in further detail:

Fig. 1 is the structural representation of the utility model.

In the figure: 1 frame, 2 fixed cylinder, 3 chute, 4 telescopic oil cylinder, 5 moving cylinder, 6 rotary mechanism locking mechanism, 7 luffing cylinder.

Detailed ways

As shown in Figure 1, a telescopic discharge hopper includes a fixed cylinder 2 and a movable cylinder 5 that can slide on the fixed cylinder to change the overall length of the fixed cylinder and the movable cylinder, both of which are opposite to the driven movable cylinder The telescopic oil cylinder 4 that the fixed cylinder slides is connected, and the slewing mechanism is rotatably supported on the frame 1. The fixed cylinder and the slewing mechanism are hinged through the hinge shaft. Oil cylinder 7, the hinge shaft axis is perpendicular to luffing oil cylinder.

The rotary position of the rotary mechanism relative to the frame is locked by the locking mechanism, so as to realize the determination of the rotary position of the unloading hopper relative to the frame. Figure 6 shows the rotary mechanism locking mechanism, which has rotary and locking functions.

The tail end of the cylinder body of the telescopic oil cylinder is connected on the support fixed on the fixed cylinder, and the piston rod head of the telescopic oil cylinder is connected on the support fixed on the movable cylinder.

The rotary mechanism includes a rotary shaft, the fixed cylinder is hinged to the upper end of the rotary shaft, the cylinder body of the luffing cylinder is hinged to the lower end of the rotary shaft, and the head of the piston rod of the luffing cylinder is hinged to the support fixed on the fixed cylinder.

The fixed cylinder is provided with a chute or a slide rail for the sliding guide of the movable cylinder, and correspondingly, a slide rail or a slide groove 3 is provided on the movable cylinder to ensure the sliding fit between the movable cylinder and the fixed cylinder.

The utility model only needs to operate the hydraulic control valve to easily extend or shorten the telescopic oil cylinder installed on the fixed cylinder and the movable cylinder, and at the same time operate the hydraulic control valve to make the luffing cylinder stretch, thereby realizing the lifting of the discharge hopper to a certain height . Compared with similar technologies, the traditional manual installation of extensions is changed to extend the length of the unloading hopper, while the telescopic unloading hopper has the advantages of simple operation and flexible length control, and can be realized by operating the telescopic cylinder within the design range. The height adjustment of the unloading hopper uses the luffing cylinder to change the angle of the unloading hopper to realize the height adjustment of the unloading hopper. The utility model is simple to install, and the material can be sent to a suitable position quickly so as to improve the work efficiency.
