Detailed Implementation

[0015] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments, but these embodiments should not be construed as limiting the present invention.

[0016] This invention designs an automatic concrete feeding device, which can be installed on the waiting hopper of a ready-mixed concrete mixer to automatically take a certain amount of concrete for testing.

[0017] Example 1 like Figure 1 As shown in the figure, this embodiment provides an automatic concrete material handling device, which mainly consists of a storage chamber 1 and a material discharging component.

[0018] The storage chamber 1 is the main part of the automatic concrete material handling device, and has an inclined cylindrical structure (see...). Figure 2 (Installation status), the material can be wear-resistant steel. The storage chamber 1 is designed with a volume of 20~30L, which is sufficient to meet the needs of making a set of standard concrete test blocks in one sampling. Several flushing holes 3 are opened on the side wall of the storage chamber 1. The flushing holes 3 can be connected to an external water source (not shown in the figure) or a high-pressure water gun (not shown in the figure) to flush the inside of the storage chamber 1 after sampling to prevent the concrete from setting.

[0019] The front end of storage chamber 1 (i.e. Figure 1 The lower left corner (middle left) is the discharge end, where a discharge assembly is installed. The discharge assembly includes a discharge gate 4, a discharge gate mounting plate 5, a pneumatic telescopic rod 6, and a telescopic rod fixing seat 7. The specific connections are as follows: The discharge gate mounting plate 5 is hinged to both sides of the discharge end of the storage chamber 1 via pins. The discharge gate 4 is an arc-shaped plate that completely covers the discharge end opening of the storage chamber 1. The middle part of the discharge gate 4 is welded to the bottom of the discharge gate mounting plate 5, allowing the discharge gate 4 to rotate around the pin of the discharge gate mounting plate 5. The telescopic rod fixing seat 7 is welded to the top of the outer wall of the storage chamber 1. The cylinder end of the pneumatic telescopic rod 6 is hinged to the telescopic rod fixing seat 7, and the piston rod end of the pneumatic telescopic rod 6 is hinged to the upper edge of the discharge gate 4.

[0020] Example 2 This embodiment is basically the same as Embodiment 1, except that: like Figure 2 As shown, this embodiment provides a mixer waiting hopper assembly with an automatic concrete receiving device, including a waiting hopper 8 and the rear end of the storage chamber 1 (i.e., Figure 1 A connecting seat 2 is welded to the upper right of the middle section. The connecting seat 2 is annular or flange-shaped, with an outer diameter larger than the outer diameter of the storage chamber 1 and an inner diameter consistent with the diameter of the storage chamber 1. It is fixed to the lower side wall of the waiting hopper 8 of the mixing plant by bolting or welding. A corresponding hole is opened on the waiting hopper 8 so that the concrete in the waiting hopper 8 can flow into the storage chamber 1 by gravity.

[0021] Working principle: Material handling stage: The pneumatic telescopic rod 6 is in the retracted state (or in the extended and locked state depending on the specific air circuit design), tightening the discharge gate 4 to close the discharge end of the storage chamber 1. When the concrete mixer discharges concrete into the waiting hopper 8, some concrete flows through the connecting seat 2 and fills the storage chamber 1.

[0022] Material Discharge Stage: When testing personnel need to take samples, place the sampling trolley (not shown in the figure) or test mold (not shown in the figure) under the automatic concrete discharging device. Control the pneumatic telescopic rod 6 to extend and push open the discharge gate 4 (e.g., Figure 1 (As shown in the figure) The discharge gate 4 flips downward around the pin shaft of the discharge gate mounting plate 5 and opens. The 20-30L of concrete stored in the storage chamber 1 slides out automatically under the action of gravity and falls into the sampling container.

[0023] Reset and Cleaning: After sampling, control the pneumatic telescopic rod 6 to reverse its movement and close the discharge gate 4. Spray water in through the flushing hole 3 to clean away any remaining concrete slurry, preparing for the next operation.

[0024] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.

[0025] The contents not described in detail in this specification are existing technologies known to those skilled in the art.
