Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Referring to fig. 1 and fig. 2, for the utility model discloses a concrete mixing device's ejection of compact structure, including going out hopper 1 and fixed discharging pipe 21 that sets up in a hopper 1 bottom. The upper end of the discharge hopper 1 is a flared end, and the lower end of the discharge hopper is a necking end, so that concrete can be conveniently discharged. The discharge pipe 21 is a circular pipe structure, and the discharge pipe 21 is communicated with the discharge hopper 1. An extension pipe 22 is sleeved on the discharge pipe 21, and the inner diameter of the discharge pipe 21 is the same as the outer diameter of the extension pipe 22. A drive for controlling the displacement of the extension tube 22 along the axis of the tapping pipe 21 is arranged on the tapping hopper 1, so that the extension tube 22 can be extended away from the tapping pipe 21.

When loading concrete transport vehicles with different specifications, the driving part is used for controlling the extension pipe 22 to extend out towards the direction far away from the discharge pipe 21, so that the fall between the discharge port of the extension pipe 22 and the feed hopper of the concrete transport vehicle is smaller. When the concrete is discharged from the discharging end of the extension pipe 22, the concrete is not easy to splash when falling on the feeding hopper of the transport vehicle.

Referring to fig. 1 and 2, a driver is provided as an electric cylinder 3. The number of the electric cylinders 3 is two, and the two electric cylinders 3 are symmetrically arranged on two sides of the extension pipe 22. One end of the cylinder body of the electric cylinder 3 is hinged with the outer wall of the discharge hopper 1, and one end of the piston rod of the electric cylinder 3 is hinged with the outer wall of the lengthening pipe 22. When the piston rod of the electric cylinder 3 is extended, the extension tube 22 is driven to extend away from the tapping tube 21.

Referring to fig. 1 and 2, in order to make the extension pipe 22 move along the tapping pipe 21 more smoothly, stoppers 211 are symmetrically disposed on the outer wall of the tapping pipe 21. The stopper 211 extends in the axial direction of the discharge pipe 21, and the length of the stopper 211 is the same as that of the discharge pipe 21. The inner wall of the extension pipe 22 is provided with a limiting groove 221 matched with the limiting block 211, and the limiting block 211 is slidably arranged in the limiting groove 221. Under the cooperation of the limiting groove 221 and the limiting block 211, the extension pipe 22 is more stable and less prone to skew when moving on the discharge pipe 21.

Referring to fig. 1 and 2, in order to prevent the concrete from splashing outside the vehicle, a protective cover 4 is integrally formed on an outer wall of the elongated tube 22, and the elongated tube 22 extends outward through the protective cover 4. When the extension tube 22 extends into the feed hopper of the concrete transporter, the protective hood 4 covers the feed hopper so that splashed concrete is caught by the protective hood 4.

Further, referring to fig. 1 and 2, in order to make the splashed concrete fall back into the feed hopper of the concrete truck, the protective cover 4 is arranged to be in an umbrella-shaped structure, and the protective cover 4 is turned upwards, so that the concrete splashed on the protective cover 4 is converged towards the direction close to the lengthened pipe 22, and the concrete is favorably fallen back into the feed hopper of the truck.

Further, referring to fig. 1 and 2, in order to prevent concrete from adhering to the shield 4, a water inlet pipe 5 is fixedly provided to the shield 4. The water inlet pipes 5 are evenly distributed on the protective cover 4. The water inlet pipe 5 penetrates through the protective cover 4, a spray head 6 is arranged at one end of a water outlet of the water inlet pipe 5, and the spray head 6 is positioned below the protective cover 4. One end of the water outlet of the spray head 6 is arranged towards the lengthening pipe 22, so that the spray head 6 is tightly attached to the protective cover 4, and water flow sprayed by the spray head 6 washes the protective cover 4 to wash away the concrete attached to the protective cover 4.

Further, referring to fig. 1 and 2, in order to increase the washing range of the water flow, the spray head 6 is a duckbill type spray head, so that the sprayed water flow covers a larger range, and the washing effect of the protective cover 4 is better.

Referring to fig. 1 and 2, in order to make the concrete discharged from the discharge outlet of elongated tube 22 converge better, the bottom end of elongated tube 22 is set to a tapered structure, and the bottom end of elongated tube 22 is gradually reduced along the direction opening deviating from discharge tube 21, so that the concrete is more easily converged and is not easily splashed outwards when discharged.

The implementation principle of the embodiment is as follows: after the concrete truck stops below the discharge hopper 1, the electric cylinder 3 is started, and the piston rod of the electric cylinder 3 drives the extension pipe 22 to extend out towards the direction close to the feed hopper of the truck, so that the protective cover 4 covers the upper part of the feed hopper, and the extension pipe 22 extends into the feed hopper. Go out hopper 1 at the in-process of unloading, the concrete falls to splash less that causes in the feeder hopper, and the concrete that partly splashes can fall on protection casing 4, falls into the feeder hopper again along the inclined plane of protection casing 4. After the blanking is finished, water flow is sprayed out of the spray head 6 to wash the protective cover 4, so that the concrete attached to the protective cover 4 falls into the feed hopper.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
