[0002] Existing concrete mixing plants have large storage containers for storing aggregates, powders and auxiliary materials. During storage, concrete powders slowly react with moisture in the air and are prone to agglomeration. In addition, the friction between the particles of concrete powders is relatively large, so when discharging, the discharge port at the bottom of the storage container is occasionally blocked, causing slow and difficult discharging.

A plurality of cutting plates are movably provided on the surface of the buffer plate. A return spring is connected to the mounting rod of the spiral feeding paddle on the inner side of the bottom end of the cutting plate. A plurality of trigger blocks for pushing the cutting plates to move are fixed on the inner wall of the storage barrel.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0020] like Figure 1-4As shown, an anti-clogging concrete powder storage container includes a storage barrel 1, a spiral feeding paddle is rotatably provided at the top of the storage barrel 1, a separation ring plate 2 is provided at the tail end of the spiral feeding paddle in the storage barrel 1, a material buffer plate 3 is rotatably provided at the bottom surface of the separation ring plate 2 in the storage barrel 1, and an anti-clogging dredging mechanism is provided in the bottom opening of the storage barrel 1; the dredging mechanism includes a mounting ring plate 4 vertically slidably provided in the bottom opening of the storage barrel 1 and a plurality of dredging plates 8 provided inside the mounting ring plate 4, the top surface of the dredging plate 8 is in the shape of an inclined blade, and the powder falls on At this time, it falls on the dredging plate 8. As the powder falls and the dredging plate 8 moves up and down, the agglomerated powder is shaken and broken. A transmission mechanism for installing the ring plate 4 is provided in the storage barrel 1. The coordination of the buffer plate 3 with the dredging mechanism and the transmission mechanism can achieve the effect of first breaking up the agglomerated powder and then discharging it. At the same time, the powder discharging speed can be reduced to avoid the powder discharging speed being too fast and accumulating at the outlet position of a fixed size. At the same time, the powder falling at the outlet can be shaken up and down to accelerate the discharge of the powder from the outlet. Example

[0021] The technical solution is basically the same as that of the first embodiment, except that Figure 1-4 As shown, the transmission mechanism includes a trigger rod 9 obliquely arranged at the bottom of the mounting rod of the spiral feeding paddle and a plurality of trigger grooves 12 opened at the top of the mounting ring plate 4. The trigger groove 12 is arc-shaped, and the bottom end of the trigger rod 9 is smooth and spherical. The buffer plate 3 is fixedly arranged with the mounting rod of the spiral feeding paddle. The buffer plate 3 is conical, and the small end faces the partition ring plate 2. A plurality of cutting plates 5 are movably arranged on the surface of the buffer plate 3. The inner side of the bottom end of the cutting plate 5 is connected to the mounting rod of the spiral feeding paddle with a reset spring 6. A plurality of trigger blocks 7 for pushing the cutting plate 5 to move are fixedly arranged on the inner wall of the storage barrel 1. The cutting plate 5 retracted into the buffer plate 3 through the trigger block 7 rebounds quickly under the action of the reset spring 6, thereby realizing the preliminary breaking up and cutting operation of the agglomerated powder. A flange ring plate 10 is fixedly provided at the bottom end of the cutting plate 5, and a limiting ring plate is fixedly provided on the outer wall of the bottom end of the storage barrel 1. A sliding rod 11 fixedly connected to the top surface of the flange ring plate 10 is slidably provided inside the limiting ring plate. A return spring is sleeved on the rod body of the sliding rod 11 located above the limiting ring plate. The return spring and the sliding rod 11 cooperate to reset the pressed mounting ring plate 4, thereby realizing the up and down reciprocating movement of the dredging plate 8 and achieving the shaking and dredging effect of the powder.

[0022] Working principle: When in use, the spiral feeding paddle is controlled to work, and the powder is transported from the bottom end of the spiral feeding paddle to the buffer plate 3, and slides along the surface of the buffer plate 3. At the same time, the buffer plate 3 rotates with the spiral feeding paddle, and the cutting plate 5 intermittently contacts the trigger block 7 and is squeezed and locked in the buffer plate 3, and cooperates with the return spring 6 to achieve a preliminary rebound cutting operation on the powder. Then, this part of the powder falls from the space between the buffer plate 3 and the storage barrel 1 to the dredging plate 8. Through the intermittent pressing of the continuously rotating trigger rod 9 and the trigger groove 12 and the cooperation of the return spring, the dredging plate 8 is realized to reciprocate up and down, thereby achieving the shaking and dredging effect of the powder.
