[0048] As Figure 2 shown, in some embodiments of the utility model, the vacuum suction machine further includes a high pressure gas storage tank 300, the output port of the high pressure gas storage tank 300 is connected to the backflushing port 106 through a control valve group 310, so as to facilitate backflushing of the filter element 110.

[0050] In some embodiments of the utility model, the high pressure gas storage tank 300 is provided with an air inlet, the air inlet is connected with an air compressor and other equipment, and the air inlet is used for supplementing the gas in the high pressure gas storage tank 300, so that the high pressure gas storage tank 300 maintains a high pressure state, and the backflushing effect is guaranteed.

[0051] As Figure 2 , Figure 3 , Figure 7 shown, in some embodiments of the utility model, the suction barrel 100 includes a barrel cover 120, the filter element 110 is arranged at the lower end opening of the barrel cover 120, so as to form the vacuum cavity 104 at the upper part of the barrel cover 120, the vacuum suction port 103 and the backflushing port 106 are arranged on the barrel cover 120, and the barrel cover 120 is detachably mounted to the barrel body of the suction barrel 100; when the barrel cover 120 is removed, the filter element 110 can be conveniently cleaned and replaced, and the maintenance of various interfaces and pipes can be facilitated.

[0052] AsFigure 3 , Figure 7 As shown, in some embodiments of this utility model, the filter element 110 is pressed and installed onto the inner wall of the bucket cover 120 by a pressure ring 111 and fasteners such as screws.

[0053] Of course, in the actual implementation process, the filter element 110 can also be installed into the barrel cover 120 by means of bonding or other methods.

[0054] like Figure 2 As shown, in some embodiments of this utility model, the high-pressure gas storage tank 300 and the control valve group 310 are arranged above the barrel cover 120 to improve the compactness of the mechanism and facilitate the application of the vacuum suction machine.

[0055] It is understood that in some embodiments of this utility model, the high-pressure gas storage tank 300 and the control valve group 310 may also be located outside the suction bucket 100, which will not be described in detail here.

[0056] like Figure 2 , Figure 3 , Figure 7 As shown, in some embodiments of this utility model, the vacuum feeder further includes a base 400, a suction bucket 100 disposed above the base 400, a switch 210 provided with a rotating shaft 220, the rotating shaft 220 being rotatably connected to the base 400, the rotating shaft 220 being provided with a rotating arm 230 extending in its radial direction, and a counterweight mechanism including a counterweight 240 slidably disposed on the rotating arm 230 and a counterweight positioning mechanism capable of positioning the relative position of the rotating arm 230 and the counterweight 240. By adjusting the position of the counterweight 240 on the rotating arm 230, adjusting the force arm of the counterweight 240, adjusting the torque, and controlling the load-bearing force of the switch 210, the material output of the vacuum feeder is adjusted.

[0057] Specifically, such as Figure 5 , Figure 6 As shown, the switch 210 and the counterweight 240 are distributed on both sides of the rotating shaft 220, forming a lever structure with the rotating shaft 220 as the fulcrum. When the weight of the material carried by the switch 210 is greater than the torque formed by the counterweight 240, the switch 210 opens. After the material is output, the switch 210 resets under the torque of the counterweight 240.

[0058] like Figure 4 As shown, in some embodiments of this utility model, the counterweight 240 is provided with a through hole that can slide with the rotating arm 230. The counterweight positioning mechanism includes a counterweight adjusting screw 250 that is threaded onto the counterweight 240. The counterweight adjusting screw 250 can be screwed into the through hole and press against the rotating arm 230, thereby positioning the counterweight 240 on the rotating arm 230. Loosening the counterweight adjusting screw 250 can adjust the position of the counterweight 240.

[0059] It is understood that in some embodiments of this utility model, the counterweight positioning mechanism may also be a magnetic fixing mechanism, in which a magnet is provided in the counterweight 240, and the counterweight 240 is fixed to the rotating arm 230 by the principle of magnetic adsorption.

[0060] It is understood that in some embodiments of this utility model, the counterweight positioning mechanism can also be a pin positioning mechanism, with multiple positioning holes distributed along its length on the rotating arm 230 and corresponding pin holes on the counterweight 240. By cooperating with the corresponding pins, the position of the counterweight 240 on the rotating arm 230 can be adjusted.

[0061] like Figure 4 As shown, in some embodiments of this utility model, the switch 210 is provided with a rotating base 260, the rotating shaft 220 is rotatably engaged with the rotating base 260, and a rotation positioning mechanism is provided between the rotating base 260 and the rotating shaft 220 to position the rotation angle of the rotating shaft 220. The relative angle between the counterweight 240 and the switch 210 is adjusted to adjust the torque formed by the counterweight 240 when the switch 210 is turned on or off.

[0062] like Figure 4 As shown, in some embodiments of this utility model, the rotatable base 260 is provided with a shaft hole that can be rotatably engaged with the rotating shaft 220. The rotation positioning mechanism includes a rotation positioning screw 270 that is threadedly engaged with the rotatable base 260. The rotation positioning screw 270 can be screwed into the shaft hole and press against the rotating shaft 220, thereby restricting the rotating shaft 220 from rotating within the shaft hole.

[0063] It is understood that in some embodiments of this utility model, the rotation positioning mechanism may also be a pin positioning structure, which will not be described in detail here.

[0064] like Figure 5 , Figure 6 As shown, in some embodiments of this utility model, the switch 210 extends obliquely downward relative to the rotating shaft 220, and the rotating arm 230 extends obliquely upward relative to the rotating shaft 220 and is distributed opposite to the switch 210. Under normal conditions, the torque generated by the counterweight 240 is greater than the torque generated by the switch 210, thereby keeping the switch 210 in contact with the discharge port 102. When the switch 210 carries a set amount of material, the torque formed at the switch 210 is greater than the torque generated by the counterweight 240. The switch 210 and the counterweight 240 rotate counterclockwise, and the switch 210 opens the discharge port 102. The torque generated by the material output at the discharge port 102 on the switch 210 and the weight of the switch 210 itself is greater than the torque formed after the counterweight 240 rotates counterclockwise, thereby maintaining the continuous output of material.

[0065] Specifically, as shown in the figure Figure 5 ,Figure 6 As shown, when the switch 210 carries a set amount of material, the torque generated at the switch 210 is greater than the torque generated by the counterweight 240. The switch 210 and the counterweight 240 rotate counterclockwise, and the switch 210 opens the discharge port 102. At the same time, since the angle α between the rotating arm 230 and the vertical plane decreases, the torque generated at the counterweight 240 also decreases. Therefore, the small force generated by the material output at the discharge port 102 is sufficient to keep the switch 210 in the open state, thereby achieving continuous material output.

[0066] In the specific implementation process, the angle α between the rotating arm 230 and the vertical plane can be adjusted by rotating the positioning mechanism, so that when the switch 210 is opened, the force exerted by the material output at the outlet 102 on the switch 210 and the torque generated by the weight of the switch 210 itself are greater than the torque generated by the counterweight 240 after counterclockwise rotation, that is, it is maintained in a better critical state to achieve continuous material output. When the material output is completed, the force exerted by the material output on the switch 210 disappears, and the torque generated by the counterweight 240 is greater than the torque generated by the weight of the switch 210 itself, so that the switch 210 resets and closes the outlet 102.

[0067] like Figure 3 As shown, in some embodiments of this utility model, the lower end of the suction bucket 100 is provided with a discharge connector 130, and the discharge port 102 is located at the discharge connector 130.

[0068] Specifically, the lower end of the discharge connector 130 is provided with a downwardly angled cut structure to form a discharge port 102, and the switch 210 extends downwardly relative to the rotating shaft 220.

[0069] like Figure 3 As shown, in some embodiments of this utility model, a maintenance port 401 is provided on the side of the base 400, and a cover plate (not shown in the figure) is installed on the maintenance port 401. The cover plate can be detachably installed on the base 400 to facilitate the adjustment of the counterweight mechanism or the maintenance and cleaning of the interior of the base 400.

[0070] In some embodiments of this utility model, the cover plate is a transparent part to form an observation window, which makes it convenient for operators to observe the working conditions inside the base 400.

[0071] Of course, this invention is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this invention. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
