Detailed implementation manner

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Embodiment: Refer to Figures 1 - 4 A rapid feeding device for a mixing plant as shown, including a feeding block 1, a quantitative feeding mechanism is arranged on the feeding block 1, a placing groove is opened at the top of the feeding block 1, and a cover plate 20 is hingedly installed at the top of the feeding block 1;

[0024] The quantitative feeding mechanism includes a movable cavity opened on the feeding block 1, a flow hole communicating with the movable cavity is opened on the inner wall of the side part of the placing groove, a material guiding plate 18 is installed on the bottom inner wall of the flow hole, a blocking unit for blocking the flow hole is arranged on the feeding block 1, a rotating rod 2 is rotatably installed on the opposite inner walls of the movable cavity, a movable block 3 is sleeved on the rotating rod 2, a fixing groove is opened at the top of the movable block 3, a weighing device 4 is installed on the bottom inner wall of the fixing groove, the weighing device 4 is a mechanical scale for weighing additives, a placing box 5 is installed on the top of the weighing device 4, a discharge hole is opened on the side part of the feeding block 1 on the inner wall of the side part of the movable cavity, a stop block 10 is arranged in the movable cavity, and a driving unit for simultaneously rotating the rotating rod 2 and moving the stop block 10 is arranged on the feeding block 1.

[0025] By means of the above mechanism, when in use, first place the feeding block 1 on the stirring cylinder of the mixing plant, and align the discharge hole with its opening. Then pour the additive into the placement groove. At this time, the additive will enter the movable cavity through the flow hole and the guide plate 18 and fall onto the placement box 5. At this time, the weighing device 4 will weigh the additive on the placement box 5. When the weight reaches the standard, the blocking unit receives the signal to block and stop feeding. When feeding is required, the driving unit is used to move the blocking block 10 upward. The upward movement of the blocking block 10 will release the blocking of the discharge hole. At the same time, the driving unit will cause the rotating rod 2 to rotate. The rotation of the rotating rod 2 will cause the movable block 3 to rotate. The rotation of the movable block 3 will cause the placement box 5 to rotate through the weighing device 4. Then the additive enters the mixing plant through the discharge hole, thus eliminating the need for workers to perform weighing operations. And through the settings of the blocking unit and the driving unit, timed feeding can be carried out to avoid the situation of affecting subsequent use due to forgetting to feed.

[0026] As Figures 2 - 4 shown, the driving unit includes a motor 6 and a PLC controller installed on the top of the feeding block 1. A moving cavity communicating with the movable cavity is opened on the feeding block 1. The opposite inner walls of the moving cavity are rotatably installed with a lead screw 7. The other end of the lead screw 7 is installed on the output shaft of the motor 6. A threaded block 8 is threadedly sleeved on the lead screw 7. The blocking block 10 is installed on the side of the threaded block 8. Two through cavities are opened on the feeding block 1. The two ends of the rotating rod 2 away from each other respectively extend into the two through cavities and are respectively installed with winding rollers 11. Pulling ropes 12 are wound on both winding rollers 11. The tops of the two through cavities are both provided with rope holes communicating with the moving cavity. The other ends of the two pulling ropes 12 respectively penetrate through the two rope holes and are installed on the side of the threaded block 8. An elastic element is arranged on the rotating rod 2. The advantage of such a setting is that through the settings of the motor 6, the lead screw 7, the threaded block 8, the winding rollers 11 and the pulling ropes 12, it is convenient to move the blocking block 10 while making the rotating rod 2 rotate.

[0027] Specifically, when feeding is required after weighing, the motor 6 is turned on through the PLC controller. The output of the motor 6 will cause the lead screw 7 to rotate. The rotation of the lead screw 7 will cause the threaded block 8 to move upward. The upward movement of the threaded block 8 will cause the blocking block 10 to move, thereby opening the discharge hole. At the same time, the upward movement of the threaded block 8 will pull the pulling rope 12. When the blocking block 10 moves to completely open the avoidance hole, the pulling rope 12 is straightened. At this time, the continuous movement of the threaded block 8 will cause the winding roller 11 to rotate through the pulling rope 12. The rotation of the winding roller 11 will cause the rotating rod 2 to rotate. The rotation of the rotating rod 2 will cause the movable block 3 to rotate. The rotation of the movable block 3 will cause the placement box 5 to rotate through the weighing device 4, and then cause the placement box 5 to tilt, so that the additive enters the mixing plant through the discharge hole.

[0028] As Figure 4As shown, the elastic element includes two torsion springs 13 mounted on the rotating rod 2, and the other ends of the two torsion springs 13 are respectively mounted on the top inner walls of the two through cavities. The advantage of this setting is that, through the setting of the torsion springs 13, it is convenient to reset the placement box 5.

[0029] Specifically, when the threaded block 8 moves downward, the tension of the pull rope 12 will be reduced. At this time, under the action of the torsion spring 13, the rotating rod 2 will rotate in the reverse reset direction. The reset rotation of the rotating rod 2 will cause the movable block 3 to reset, and further cause the placement box 5 to reset, thus facilitating weighing next time.

[0030] As Figure 2 shown, guide rods 9 are mounted on the opposite inner walls of the moving cavity. A guide hole is opened at the bottom of the threaded block 8, and the guide rods 9 penetrate through the guide holes. The advantage of this setting is that, through the setting of the guide rods 9, it is convenient to make the threaded block 8 move along the horizontal direction.

[0031] As Figure 2 shown, the plugging unit includes a plugging cavity opened on the feeding block 1 and communicating with the flow hole. An electric push rod 14 is mounted on the top inner wall of the plugging cavity, and an L-shaped baffle 15 is mounted on the output end of the electric push rod 14. The advantage of this setting is that, through the setting of the electric push rod 14 and the L-shaped baffle 15, it is convenient to plug the flow hole.

[0032] Specifically, when the weight on the placement box 5 reaches a certain value, the electric push rod 14 will be started through PLC control. The output of the electric push rod 14 will cause the movement of the L-shaped baffle 15, and then plug the flow hole, thereby stopping the movement of the additive into the placement box 5.

[0033] As Figure 2 shown, a telescopic hydraulic cylinder 16 is mounted on the bottom inner wall of the placement groove, and a triangular bottom plate 17 is mounted on the output end of the telescopic hydraulic cylinder 16. The advantage of this setting is that, through the setting of the telescopic hydraulic cylinder 16 and the triangular bottom plate 17, it is convenient to make the lower additive pass through the flow hole.

[0034] Specifically, when the additive is lower than the flow hole, the telescopic hydraulic cylinder 16 is started. The output of the telescopic hydraulic cylinder 16 will cause the movement of the triangular bottom plate 17, and the movement of the triangular bottom plate 17 will cause the additive to rise, so that the lower additive passes through the flow hole, avoiding waste.

[0035] As Figure 1 shown, a protective shell is mounted on the top of the feeding block 1, and an L-shaped shielding plate 19 is mounted on the side of the feeding block 1. The advantage of this setting is that, through the setting of the protective shell, it is convenient to protect the motor 6 and the PLC controller. Through the setting of the L-shaped shielding plate 19, it is convenient to protect the discharge hole and avoid being affected by the external environment.

[0036] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
