Technical Field

[0001] The utility model relates to the technical field of feeders, in particular to a vibrating feeder. Background Art

[0002] Vibrating feeders, also known as vibrating feeders, can evenly, regularly, and continuously feed bulk and granular materials from a storage bin to a receiving device during the production process. In sand and gravel production lines, they can continuously and evenly feed crushers and perform coarse screening of materials. They are widely used in combined crushing and screening equipment in industries such as metallurgy, coal mining, mineral processing, building materials, chemicals, and abrasives.

[0003] After searching, it was found that a patent with patent number CN221564534U discloses a vibrating feeder, including a base plate, a support plate 1 and a support plate 2 are respectively provided on both sides of the base plate. The side of the support plate 1 away from the support plate 2 is provided with a motor, and the output end of the motor is provided with a screw, and the other end of the screw is rotatably connected to the support plate 2. The screw is threadedly connected to a movable frame, and by setting an adjustable support structure, the motor drives the screw to rotate, thereby driving the movable frame to move back and forth, raising or lowering one end of the fixed plate, thereby adjusting the angle of the conveying trough, and under the action of the guide rod, the device can be relatively stable when adjusting the angle, and is easy to use. However, when the movable frame moves to a position close to the middle of the fixed plate, the center of gravity will be unstable, and it will be difficult to feed the feed port at this time. If the hinged parts at the feeding support plate 2 and the fixed plate are subjected to a large tension, it will be inconvenient to continuously feed the feed port in this case, and a vibrating feeder is urgently needed to solve the above-mentioned problems.

DETAILED DESCRIPTION

[0026] See also Figure 1-4 , further illustrate the embodiments of the present utility model;

[0027] A vibrating feeder for feeding mineral powder includes a support plate 1, a support plate 28 and an inclined plate 15. The support plate 1 and the support plate 28 are distributed left and right. The lower end of the inclined plate 15 is hinged to the support plate 1, and the upper end is connected to the top of the support plate 28 in a rolling manner. For example, a row of rollers 10 are installed on the top of the support plate 28. The rollers 10 are all connected to the bottom of the inclined plate 15 in a rolling manner. The support plate 1 and the support plate 28 are both used to support the inclined plate 15. When the support plate 28 moves, the roller 10 on its top will roll at the bottom of the supporting inclined plate 15, and the inclined plate 15 is arranged parallel to the top. There is a hopper 16, and a feed port 17 is provided at the upper end of the hopper 16. Materials can be added to the hopper 16 from the feed port 17. Several high-strength springs 19 are fixed between the hopper 16 and the inclined plate 15. A vibrator 18 is installed at the bottom of the hopper 16. When the feeder is in use, the lower end of the hopper 16 is aligned with the receiving device, and the vibrator 18 is started to vibrate the hopper 16 to feed the receiving device. The vibration force exerted on the hopper 16 will be transmitted to the high-strength spring 19, and the high-strength spring 19 can buffer the vibration force. The above design is the same as the design of CN221564534U and will not be repeated here.

[0028] The cam 15 is fixed to the bottom of the support plate 1 and the support plate 2, and a plurality of universal wheels 2 are installed between the two connecting rods 4. The universal wheels 2 are provided with brake pads. When adjusting, the left universal wheel 2 is braked with the brake pads to prevent the left universal wheel 2 from rolling. The electric push rod 16 is started to apply a left pulling force to the right connecting rod 4 and the support plate 2 8, thereby driving the universal wheel 2 at the bottom of the support plate 2 8 to roll, so that the support plate 2 8 moves to the left. In this process, the roller 10 on the top of the support plate 2 8 will roll at the bottom of the inclined plate 15, thereby realizing stable adjustment of the angle of the inclined plate 15. Compared with the structure of CN221564534U, the structure of the universal wheel 2 is simpler, and the design of the universal wheel 2 not only facilitates the angle adjustment of the inclined plate 15, but also facilitates the movement of the feeder to the required position.

[0029] In order to solve the problem that when the angle of the inclined plate 15 is adjusted, the center of gravity of the feeder is unstable due to the left movement of the support plate 2 8 (moving to the middle of the bottom of the inclined plate 15), making it difficult to stably and continuously feed the hopper 16, a power support assembly is installed on the side of the support plate 2 8 near the upper end of the inclined plate 15, and a number of universal wheels 2 are installed at the bottom of the power support assembly. A PLC controller 3 electrically connected to the power support assembly is installed on the support plate 1.

[0030] Among them, the power support assembly includes a first drive member, a second drive member and a support frame. The first drive member is installed on the right connecting rod 4, and the output end of the first drive member passes through the support plate 2 8. The second drive member is installed at the output end of the first drive member, and the support frame is installed at the output end of the second drive member. The support frame is rollingly connected to the bottom of the inclined plate 15, and several universal wheels 2 at the bottom of the power support assembly are installed at the bottom of the second drive member.

[0031] Furthermore, the first driving member includes an electric push rod 29; the second driving member includes an electric cylinder 11 and a support leg 12, the support leg 12 is fixed to the output end of the electric push rod 29, the electric cylinder 11 is fixed on the support leg 12, and several universal wheels 2 at the bottom of the second driving member are installed at the bottom of the support leg 12; the support frame includes a mobile frame 13 and several rollers 2 14, the mobile frame 13 is located above the support leg 12 and is fixedly connected to the output end of the electric cylinder 11, and several rollers 2 14 are all installed on the top of the mobile frame 13, and the rollers 2 14 are all rollingly connected to the bottom of the inclined plate 15; the electric push rod 29 and the electric cylinder 11 are both electrically connected to the PLC controller 3.

[0032] This solution works as follows:

[0033] During adjustment, the PLC controller 3 will simultaneously start the electric push rod 2 9 and the electric push rod 1 6, but the movement directions of the output ends of the electric push rod 2 9 and the electric push rod 1 6 are always opposite. For example, if the electric push rod 1 6 drives the right connecting rod 4 to move left, then the electric push rod 2 9 drives the second driving member and the support frame to move right. During this process, the inclination angle of the inclined plate 15 and the hopper 16 becomes larger and larger, and the support plate 2 8 and the roller 10 thereon gradually approach the middle of the bottom of the inclined plate 15, while the support leg 12 gradually moves away from the support plate 2 8. Figure 3 As shown, the support leg 12 will drive the universal wheel 2 at its bottom to roll, and at the same time, the PLC controller 3 will calculate the stroke of the electric push rod 1 6 and the electric push rod 2 9 in real time to calculate the inclination angle of the inclined plate 15 and the height that the electric cylinder 11 needs to rise, thereby ensuring that the roller 2 14 on the mobile frame 13 always rolls at the bottom upper end of the inclined plate 15, that is, the power support component supports the upper end of the inclined plate 15 in real time, effectively solving the problem that when the angle of the inclined plate 15 is adjusted, the center of gravity of the feeder is unstable due to the left movement of the support plate 2 8 (moving to the middle of the bottom of the inclined plate 15), and it is difficult to stably and continuously feed the hopper 16; if the electric push rod 1 6 drives the right connecting rod 4 to move right, then the electric push rod 2 9 drives the second driving member and the support frame to move left, as shown in FIG. Figure 1 As shown in FIG. 2 , the support plate 2 8 and the support legs 12 are folded together.

[0034] In order to ensure the stable movement of the output ends of the electric push rod 1 6 and the electric push rod 2 9, mounting grooves 5 are opened at the right end of the connecting rod 4 and the side of the support plate 2 8. The electric push rod 1 6 and the electric push rod 2 9 are respectively installed in the left and right mounting grooves 5, and the output ends of the electric push rod 1 6 and the electric push rod 2 9 are both rollingly sleeved with limit rings 7, which are fixed in the adjacent mounting grooves 5. The limit rings 7 play a role of limiting and supporting the output ends of the electric push rod 1 6 (electric push rod 2 9).
