Description

Technical Field

[0001] The present invention relates to the technical field of vibrating sizing equipment, and specifically relates to a dual-station material vibrating feeding and sizing equipment. Background Art

[0002] Sizing is a key procedure in sample preparation, aiming to reduce the amount of the sample. In the mechanized sampling process of bulk materials such as minerals in ports, mines, power plants, and steel enterprises, a sizing procedure is often required.

[0003] The existing sizing equipment mostly adopts a single-machine setting, which cannot complete the sizing processing of materials with various sizing requirements, cannot well meet the actual sampling needs, and cannot timely remove and clean the dust waste generated during sampling, resulting in relatively large pollution. Summary of the Invention

[0004] The purpose of the present invention is to provide a dual-station material vibrating feeding and sizing equipment to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the present invention provides the following technical solutions:

[0006] A dual-station material vibrating feeding and sizing equipment includes a frame. Two feeding and sizing units are symmetrically arranged on the inner wall of the frame, and a material receiving and converting mechanism is arranged between the two feeding and sizing units;

[0007] The feeding and sizing unit includes a feed hopper. A flip cover sealing plate is arranged above the feed hopper. A docking plate is fixedly connected to the top of the feed hopper. A docking groove is opened in the middle of the docking plate. One side of the docking plate is rotatably connected to a cover plate frame. A connecting shaft is fixedly connected to the middle of the cover plate frame. The top of the cover plate frame is fixedly connected to the flip cover sealing plate. The width of the flip cover sealing plate is the same as the width of the docking groove;

[0008] A flip cover mechanism for driving the flip cover sealing plate to rotate is arranged on one side of the feed hopper. The flip cover mechanism includes a mounting frame fixedly connected to the frame. A sealing cylinder is rotatably installed on one side of the mounting frame. The output end of the sealing cylinder is fixedly connected to a driving connecting rod. One end of the driving connecting rod is snap-fitted to the middle of the connecting shaft; A feeding hose is fixedly connected to the bottom of the feed hopper. A vibrating feeder is fixedly connected to the bottom of the feeding hose. A sealing baffle is slidably connected to the discharge port of the vibrating feeder. An outlet adjusting cylinder for driving the sealing baffle to move is arranged at one end of the sealing baffle. The output end of the outlet adjusting cylinder is fixedly connected to one end of the sealing baffle;

[0009] Below the vibrating feeder, there is an adjusting mechanism for adjusting the position of the discharging port of the vibrating feeder. The adjusting mechanism includes a swinging cylinder. The upper part of the swinging cylinder is fixed to the vibrating feeder. When the swinging cylinder works, the working position of the vibrating feeder can be adjusted. Its working positions are two, one is the material receiving position, and the other is the dust removal position.

[0010] The material receiving conversion mechanism includes a servo motor. The output end of the servo motor is fixedly connected with a rotating table. The top of the rotating table is fixedly connected with a carrying material receiving tray. Several sample cups are placed on the top of the carrying material receiving tray. Two jacking mechanisms are symmetrically arranged at the bottom of the carrying material receiving tray. The jacking mechanism includes a weighing sensor. The top of the weighing sensor is fixedly installed with a weighing jacking cylinder. The output end of the weighing jacking cylinder is fixedly connected with a jacking plate. When the cylinder jacks up, the top of the jacking plate contacts the bottom of the sample cup. One end of the vibrating feeder is fixedly connected with a dust removal pipeline. The end of the dust removal pipeline far away from the vibrating feeder is bent upward.

[0011] At the dust removal position at one end of the vibrating feeder, there is a dust removal pipeline. One end of the dust removal pipeline is connected with a dust removal fan. When the vibrating feeder is in the dust removal position, the dust removal fan operates to remove the residual materials and dust inside the vibrating feeder and the connected pipelines.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: By setting two feeding and reducing units and cooperating with the material receiving conversion mechanism, the present invention realizes synchronous material receiving for the two feeding and reducing units, enabling the device to perform vibrating reduction on two kinds of materials simultaneously. During the reduction operation, the discharging state of the vibrating reduction machine is adjusted by driving the sealing baffle plate to move through the discharging adjusting cylinder. Cooperating with structures such as weighing sensors, accurate control of the sampling amount of the sample cup is achieved.

[0013] After the feeding and material receiving are completed, the present invention sets up a dust removal mechanism to clean the residual materials and dust inside the device, thereby improving the cleanliness inside the device and facilitating subsequent reduction operations. The discharging rack is driven to rotate by the swinging cylinder, and then the discharging port of the vibrating reduction machine is driven to move, enabling it to switch between two working states of discharging and dust removal, making the use of the device more flexible and efficient.

Specific embodiments

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with 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.

[0020] Please refer to Figures 1-4 , in the embodiment of the present invention, a double-station material vibrating feeding and reducing equipment includes a frame 15. Two feeding and reducing units are symmetrically arranged on the inner wall of the frame 15, and a receiving and converting mechanism is arranged between the two feeding and reducing units;

[0021] The feeding and reducing unit includes a feed hopper 1. A flip cover sealing plate 2 is arranged above the feed hopper 1. A docking plate is fixedly connected to the top of the feed hopper 1. A docking groove is opened in the middle of the docking plate. One side of the docking plate is rotatably connected to a cover plate frame. A connecting shaft is fixedly connected to the middle of the cover plate frame. The top of the cover plate frame is fixedly connected to the flip cover sealing plate 2. The width of the flip cover sealing plate 2 is the same as the width of the docking groove, so that the flip cover sealing plate 2 can be stably engaged with the docking plate, improving its sealing ability for the feed hopper 1;

[0022] A flip cover mechanism for driving the flip cover sealing plate 2 to rotate is arranged on one side of the feed hopper 1. The flip cover mechanism includes a mounting frame fixedly connected to the frame 15. A sealing cylinder 3 is rotatably installed on one side of the mounting frame. The output end of the sealing cylinder 3 is fixedly connected to a drive link 16. One end of the drive link 16 is snap-fitted to the middle of the connecting shaft; driving the flip cover to rotate through the flip cover mechanism to realize automatic opening and closing of the feed hopper 1;

[0023] A feeding hose is fixedly connected to the bottom of the feed hopper 1, and a vibrating feeder 4 is fixedly connected to the bottom of the feeding hose. A sealing baffle plate is slidably connected to the discharge port of the vibrating feeder 4, and a discharge regulating cylinder 6 for driving the seal baffle plate to move is provided at one end of the seal baffle plate, and the output end of the discharge regulating cylinder 6 is fixedly connected to one end of the seal baffle plate; the discharge regulating cylinder 6 drives the seal baffle plate to move, so as to adjust the discharge state of the vibrating feeder 4, and cooperates with structures such as a weighing sensor 7 to achieve accurate control of the sampling amount of the sample cup 12;

[0024] An adjusting mechanism for adjusting the position of the discharge port of the vibrating feeder 4 is provided below the vibrating feeder 4. The adjusting mechanism includes a swing cylinder 5. The upper part of the swing cylinder 5 is fixed to the vibrating feeder 4. When the swing cylinder 5 is working, the working position of the vibrating feeder 4 can be adjusted. The working position is divided into two, one is the material receiving position, and the other is the dust removal position.

[0025] The material receiving conversion mechanism includes a servo motor 9, the output end of the servo motor 9 is fixedly connected to a rotating table, and the top of the rotating table is fixedly connected to a material receiving tray 11. In this embodiment, four sample cups 12 arranged at equal distances are placed on the top of the material receiving tray 11. The output position close to the two vibrating feeders 4 is called the filling station, and the other two placement slots are located away from the two vibrating feeders 4, which are called the unloading stations.

[0026] Two lifting mechanisms are symmetrically arranged at the bottom of the material receiving plate 11, and the lifting mechanisms include a weighing sensor 7, a weighing lifting cylinder 8 is fixedly installed on the top of the weighing sensor 7, and a lifting plate is fixedly connected to the output end of the weighing lifting cylinder 8. When the cylinder is lifted, the top of the lifting plate contacts the bottom of the sample cup 12; the lifting plate is driven by the weighing lifting cylinder 8 to move up and down, and then the sample cup 12 is driven to move up and down, so that the sample cup 12 can be stably docked with the discharge position of the vibrating feeder 4, so as to achieve stable reception of the material;

[0027] One end of the vibrating feeder 4 is fixedly connected with a dust removal pipe 13 , and one end of the dust removal pipe 13 away from the vibrating feeder 4 is bent upward.

[0028] A dust removal pipe 13 is provided at the dust removal position at one end of the vibrating feeder 4, and a dust removal fan is connected to one end of the dust removal pipe 13. When the vibrating feeder 4 is in the dust removal position, the dust removal fan runs to remove residual materials and dust inside the vibrating feeder 4 and the connected pipes.

[0029] When the present invention is in use, first, the feeding operation of the material to be reduced is carried out. The sealing cylinder 3 starts to retract, driving the driving connecting rod 16 to rotate. The rotation of the driving connecting rod 16 drives the connecting shaft to rotate, and then drives the cover plate frame to rotate, causing the flip cover sealing plate 2 to flip open. The material to be reduced is fed in by an external feeding device. After the feeding is completed, the sealing cylinder 3 acts again, driving the flip cover sealing plate 2 to flip and close, closing the feeding hopper 1. The material entering the feeding hopper 1 enters the vibrating feeder 4 along the feeding hopper 1 and the feeding hose for vibrating and reducing operation.

[0030] When the discharging operation of the vibrating feeder 4 is required, two weighing lifting cylinders 8 drive the lifting plate and the sample cup 12 to lift. Then the discharging adjusting cylinder 6 starts, driving the sealing baffle to move, so that the material in the vibrating feeder 4 enters the sample cup 12 from the discharging port. By comparing the weight detected by the weighing sensor 7 with the initial weight of the sample cup 12, the weight of the material entering the sample cup 12 is judged. When the material weight meets the preset value, the discharging adjusting cylinder 6 starts, driving the sealing baffle to move to close the output end of the vibrating feeder 4, and at the same time the vibrating feeder 4 stops working. Then the two weighing lifting cylinders 8 retract, and the sample cup 12 falls onto the bearing receiving tray 11 under the action of gravity.

[0031] Then the servo motor 9 starts, driving the rotating platform 10 and the bearing receiving tray 11 to rotate, so that the subsequent sample cup 12 to be filled with samples moves to the filling station, and the sample cup 12 that has completed the material transfer moves to the discharging station. After repeating the feeding operation, the feeding and fixed-quantity reduction can be completed.

[0032] The swing cylinder 5 starts to work, driving the discharging port of the vibrating feeder 4 to turn to the dust removal pipeline 13. The other end of the dust removal pipeline 13 is connected with a dust removal fan. The dust removal fan operates to remove the residual material and dust inside the vibrating feeder 4 and the connected pipeline.

Although the present invention has been disclosed as above with a preferred embodiment, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to it as equivalent embodiments within the scope of the technical solution of the present invention. However, as long as it does not depart from the content of the technical solution of the present invention, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
