Description

Technical Field

[0001] The utility model belongs to the technical field of concrete pouring, and particularly relates to a novel concrete unloading device. Background Art

[0002] The Chinese utility model patent with publication number CN219298801U discloses a segmented concrete unloading device, including a receiving box, a discharge pipe and a slide. The receiving box is used to receive concrete materials dumped by a tank truck, and the discharge pipe is used to guide the concrete materials in the receiving box to the slide. A double-section slide is placed at an angle, and discharge holes are respectively opened on the upper and lower sections of the slide, and a pull-out slide is provided at the discharge hole as a switch; the slide is pulled out to open the corresponding discharge hole on the slide to realize pouring at the corresponding position; a speed bump is set to control the sliding speed of concrete in the slide.

[0003] The above-mentioned prior art has the following defects in practical applications:

[0004] (1) The effect of controlling the sliding speed of concrete by simply setting up speed bumps is poor, which is reflected in two aspects: first, when the discharge speed of the discharge pipe is fast, the speed bumps can only block the concrete in the lower layer, and basically have no effect on preventing the upper concrete from sliding; the setting of speed bumps blocks the sliding of the lower concrete, and this part of the concrete stagnates for a long time. Once the stagnation time exceeds 2 hours, it exceeds the service life and can only be scraped and discarded as construction waste, which not only wastes construction materials but also increases the workload of scraping and cleaning.

[0005] (2) Only one material discharge hole can be selectively opened on the upper and lower sections of the slide. If you want to implement simultaneous casting of the upper and lower sections, it is basically difficult to achieve.

[0006] (3) The distance between the two feeding holes on the upper and lower slides cannot be adjusted. Once the adjacent wall being cast changes slightly, the multiple feeding holes will lose their meaning. Utility Model Content

[0007] The technical problem to be solved by the utility model is to make up for the deficiencies of the prior art and provide a novel concrete unloading device.

[0008] To solve the above technical problems, the technical solution of the present utility model is:

[0009] A new type of concrete unloading device includes a frame with several casters at the bottom of the frame; a material receiving box and a material discharge box channel are fixedly provided on the frame, the material discharge box channel is arranged below the material receiving box, and a Y-shaped tee is arranged below the material discharge box channel; a discharge port I at the bottom of the material receiving box is connected to a feed port II of the material discharge box channel, and a discharge port II of the material discharge box channel is connected to a feed port III of the Y-shaped tee; an auger is provided in the inner cavity of the material discharge box channel, and the auger is rotatably connected to the material discharge box channel; the Y-shaped tee includes a main pipeline, a branch pipeline A and a branch pipeline B that are interconnected, a material discharge gate A is provided between the main pipeline and the branch pipeline A, and a material discharge gate B is provided between the main pipeline and the branch pipeline B, and the material discharge gate A and the material discharge gate B are respectively provided with a switching door mechanism.

[0010] Furthermore, the rotation of the auger is driven by a motor.

As shown Figure 3 and Figure 5 As shown, the Y-shaped tee pipe 8 includes a main pipe 801, a branch pipe A802 and a branch pipe B803 that are interconnected. A blanking gate A11 is provided between the main pipe 801 and the branch pipe A802, and a blanking gate B12 is provided between the main pipe 801 and the branch pipe B803. The blanking gate A11 and the blanking gate B12 are respectively equipped with a switch door mechanism 9. Figure 7As shown, open the blanking gate A11, the main pipeline 801 and the branch pipeline A802 are connected; open the blanking gate B12, the main pipeline 801 and the branch pipeline B803 are connected. Figure 5 As shown, when the blanking gate A11 is closed, the main pipeline 801 and the branch pipeline A802 are not connected; when the blanking gate B12 is closed, the main pipeline 801 and the branch pipeline B803 are not connected.

[0027] like Figure 3 As shown, the door opening and closing mechanism 9 includes a hinge lug A901, an operating link 902, a handle 903, a Y-shaped link 904, and a hinge lug B905.
