[0002] The existing viscous material delivery and supply generally adopts a pumping mechanism / pumping device, which generally includes a hopper, and a delivery pump is arranged at the bottom of the hopper. The material in the hopper is sucked by the delivery pump and then pumped to other equipment or components. For example, a swing mechanism and concrete pumping equipment with application number 202122391029.5, and a concrete pumping mechanism hopper installation structure and concrete pump truck with application number 201910274949.3, due to the small size of the hopper and the small amount of material stored, if the speed of hopper feeding is difficult to catch up with the speed of discharging, it is difficult to meet the requirements of continuous pumping and discharging at the bottom of the hopper. Utility Model Content

[0003] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a pumping feeding device which increases the volume of stored materials, meets the requirements of continuous pumping out of materials at the bottom of the hopper and improves the operating efficiency.

[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0005] A pumping feeding device comprises a hopper, wherein one side of the bottom of the hopper is provided with a discharge port, and the other side is provided with at least two pumping ports, each of the pumping ports is connected to a pumping pump, and the pumping pump is located outside the hopper, the discharge port of the hopper is provided with a discharge mechanism that can rotate and selectively connect with the pumping port, and the top of the hopper is connected to a silo.

[0006] As a further improvement of the above technical solution:

[0007] An amplification port is arranged on the side wall of the silo, and an amplification chamber connected with the amplification port is arranged on the outside of the silo.

[0008] The bottom of the amplification chamber is tilted, and one end of the amplification chamber close to the hopper is lower than the other end.

[0009] A spiral feeding mechanism is provided at the bottom of the amplification chamber for conveying the material in the amplification chamber to the hopper.

[0010] The spiral feeding mechanism includes a spiral blade and a rotary drive member. The rotary drive member is arranged at one end of the amplification chamber away from the hopper. One end of the spiral blade is fixedly connected to the output shaft of the rotary drive member, and the other end extends toward the amplification port.

[0011] An openable door panel is provided at the amplification port.

[0012] Slots are provided on both sides of the amplification port, and the two sides of the door panel are movably inserted into the slots on both sides of the amplification port, and a pull-out portion is provided on the door panel.

[0013] The tops of the silo and the amplification chamber are open, and the pumping feeding device includes a top cover, which is arranged on the tops of the silo and the amplification chamber and pressed against the top of the door panel, and a feed port is arranged on the top cover.

[0014] The amplification chamber and the pumping pump are located on the same side of the hopper, and the amplification chamber is located above the pumping pump.

[0015] A stirring mechanism is arranged in the hopper.

[0016] Compared with the prior art, the advantages of the utility model are:

[0017] In the pumping feeding device of the utility model, the discharge of the hopper (i.e., the supply of the external equipment) is alternately drawn from the hopper by each pumping pump, and then alternately docked with the discharge mechanism to push the material out of the hopper. For example, there are only two pumping pumps, and while one pumping pump sucks the material in the hopper, the other pumping pump docks with the discharge mechanism to push the material through the discharge mechanism. Since there is a silo docked at the top of the hopper, the silo can store materials to meet the requirement of continuous pumping of the pumping pump within a certain period of time, and the pumping pump will not be sucked empty due to lack of material in the hopper. That is, the pumping feeding device increases the storage volume of materials to meet the requirement of continuous pumping discharge at the bottom of the hopper, thereby improving the working efficiency.

[0029] Embodiment 1:

[0030] Figures 1 to 3 An embodiment of the pumping feeding device of the utility model is shown. The pumping feeding device of this embodiment includes a hopper 1. A discharge port 11 is provided on one side of the bottom of the hopper 1, and at least two pumping ports 12 are provided on the other side. Each pumping port 12 is connected to a pumping pump 2. The pumping pump 2 is located outside the hopper 1. The discharge port 11 of the hopper 1 is provided with a discharge mechanism 3 which can be rotatably connected to the pumping port 12 for selective connection. The top of the hopper 1 is connected to a silo 4.

[0031] The discharge of the hopper 1 (i.e., the supply of the external device) is alternately drawn from the hopper 1 by each pumping pump 2, and then alternately docked with the discharge mechanism 3 to push the material out of the hopper 1. For example, there are only two pumping pumps 2, and while one pumping pump 2 sucks the material in the hopper 1, the other pumping pump 2 docks with the discharge mechanism 3 to push the material out through the discharge mechanism 3. Since the silo 4 is docked at the top of the hopper 1, the silo 4 can store the material, meeting the requirement of continuous pumping of the pumping pump 2 within a certain period of time, and the pumping pump 2 will not be sucked empty due to lack of material in the hopper 1. That is, this pumping feeding device increases the volume of stored material, meets the requirement of continuous pumping discharge at the bottom of the hopper 1, and thus improves the working efficiency.

[0032] Furthermore, in this embodiment, an amplification port 51 is provided on the side wall of the silo 4, and an amplification chamber 5 connected to the amplification port 51 is provided on the outside of the silo 4. The silo 4 is connected to the amplification chamber 5 through the amplification port 51, further increasing the temporary storage capacity of the material.

[0033] Furthermore, in this embodiment, the bottom of the amplification chamber 5 is tilted, and one end of the amplification chamber 5 close to the hopper 1 is lower than the other end, so as to facilitate the flow of materials toward the hopper 1 .

[0034] Furthermore, in this embodiment, a screw feeding mechanism 6 is provided at the bottom of the amplification chamber 5 for conveying the material in the amplification chamber 5 to the hopper 1. Under the conveying action of the screw feeding mechanism 6, the amplification chamber 5 is prevented from being blocked. It is particularly suitable for conveying viscous materials.

[0035] Furthermore, in this embodiment, the spiral feeding mechanism 6 includes a spiral blade 61 and a rotating driving member 62. The rotating driving member 62 is arranged at one end of the amplification chamber 5 away from the hopper 1. One end of the spiral blade 61 is fixedly connected to the output shaft of the rotating driving member 62, and the other end extends toward the amplification port 51.

[0036] Furthermore, in the present embodiment, the silo 4 has a structure that is larger at the top and smaller at the bottom. Specifically, the upper portion of the silo 4 is square and has an open top. The top of the amplification chamber 5 is open, and an arc-shaped groove is formed at the bottom of the amplification chamber 5. The spiral blade 61 is coaxial with the arc-shaped groove, and the middle portion of the amplification chamber 5 is in an inverted figure eight shape.

[0037] Furthermore, in this embodiment, the amplification chamber 5 and the pumping pump 2 are located on the same side of the hopper 1, and the amplification chamber 5 is located above the pumping pump 2. The structural arrangement is compact and beautiful.

[0038] Furthermore, in this embodiment, a stirring mechanism 9 is provided in the hopper 1. The stirring mechanism 9 is used to stir the material in the hopper 1.

[0039] Further, in this embodiment, the discharge mechanism 3 includes a discharge pipe and a driving docking mechanism for driving the discharge pipe to rotate, one end of the discharge pipe is rotationally connected to the discharge port 11, and the other end is selectively docked with each pumping port 12. Specifically, the central axis of the other end of the discharge pipe (the end selectively docked with each pumping port 12) is parallel to or does not overlap with the rotation axis of the discharge pipe.

[0040] Embodiment 2:

[0041] Figure 4 Another embodiment of the pumping feeding device of the utility model is shown. The structure of the pumping feeding device of this embodiment is basically the same as that of the first embodiment, and the only difference is that in this embodiment, an openable door panel 7 is provided at the amplification port 51. When the amplification chamber 5 is not in use, the door panel 7 is used to isolate the material bin 4 and the amplification chamber 5, so as to prevent the material in the material bin 4 from entering the amplification chamber 5, thereby reducing the cleaning work of the amplification chamber 5.

[0042] Furthermore, in this embodiment, both sides of the amplification port 51 are provided with slots 511, and both sides of the door panel 7 are movably inserted into the slots 511 on both sides of the amplification port 51, and a pull-out portion 71 is provided on the door panel 7. The door panel 7 is pluggably installed at the amplification port 51, and the switch operation is convenient.

[0043] Embodiment three:

[0044] Figure 5 Another embodiment of the pumping feeding device of the utility model is shown. The structure of the pumping feeding device of this embodiment is basically the same as that of the second embodiment, and the only difference is that in this embodiment, the tops of the silo 4 and the amplification chamber 5 are open, and the pumping feeding device includes a top cover 8, which is arranged on the tops of the silo 4 and the amplification chamber 5 and pressed against the top of the door panel 7, and a feed port 81 is provided on the top cover 8. The tops of the silo 4 and the amplification chamber 5 are sealed by the top cover 8 to prevent the material from splashing out, and at the same time, the interior of the hopper 1, the silo 4 and the amplification chamber 5 (relatively sealed space, which can be connected to an external air pressure maintenance mechanism) can be maintained within a certain pressure range. In addition, the door panel 7 is pressed by the top cover 8 to prevent the door panel 7 from loosening.

[0045] Specifically, the top cover 8 is detachably mounted on the top of the silo 4 and the amplification chamber 5, such as by screws. On the one hand, when the amplification chamber 5 needs to be used, the top cover 8 can be opened, the door panel 7 can be pulled out, and then the top cover 8 can be covered to connect the amplification chamber 5 with the silo 4; on the other hand, it is convenient to clean and maintain the interior of the pumping feeding device.
