[0020] In order to further explain the technical solution of the present utility model, it is described in detail through specific embodiments below.

[0021] See also Figure 1 The utility model provides a feeding device for a particle vibrating screen machine, comprising a feeding hopper 1, a discharge port 2 and a flow regulating device 3. The discharge port 2 is arranged at the bottom of the feeding hopper 1, and the flow regulating device 3 is arranged inside the feeding hopper 1.

[0022] See also Figure 2-5 The utility model provides a feeding device for a particle vibrating screen machine. The flow regulating device 3 includes a connecting cavity 31, a baffle 32, a slide groove 33, a threaded sleeve 34, a connecting seat 35, a screw 36, a hand wheel 37 and a bevel gear set 38. The left and right side walls of the feed hopper 1 are both provided with connecting cavities 31. The bottom of the connecting cavity 31 is connected with the discharge port 2. A baffle 32 is slidably installed inside the connecting cavity 31, and the baffle 32 can slide out of the connecting cavity 31 and extend into the inner side of the discharge port 2. By controlling the baffle 32 to move to both sides of the discharge port 2 to block it, the diameter of the discharge port 2 is reduced, so that the material can flow through the discharge port 2. The amount is adjusted, a slide groove 33 is provided on the bottom surface of the connecting cavity 31, and the slide groove 33 passes through the bottom of the hopper 1, a threaded sleeve 34 is slidably installed on the inner side of the slide groove 33, and the threaded sleeve 34 passes through the slide groove 33 and is fixed with screws to the baffle 32, and a connecting seat 35 is welded on the bottom surfaces of the left and right sides of the hopper 1, a screw rod 36 is rotatably installed on the inner side of the connecting seat 35, the threaded sleeve 34 is sleeved on the surface of the screw rod 36 and is threadedly connected with it, a hand wheel 37 is rotatably installed on the bottom of the head end of the connecting seat 35, and a bevel gear group 38 is installed inside the head end of the connecting seat 35, and the hand wheel 37 is transmission connected with the screw rod 36 through the bevel gear group 38.

[0023] To further explain, the axial direction of the hand wheel 37 is parallel to the plumb line, so that the hand wheel 37 is easy to operate and use.

[0024] To further explain, the baffle 32 is made of 45# steel, which is a high-quality carbon structural steel, ensuring that the baffle 32 has sufficient strength and deformation resistance.

[0025] It is further explained that the maximum travel distance of the baffle 32 is not less than 30% of the length of the discharge port 2, so that the baffle 32 has a good adjustment margin and can adjust the caliber of the discharge port 2 according to materials of different particle sizes.

[0026] It is further explained that the connecting cavity 31 is designed to be inclined, and the inclination angle of the connecting cavity 31 is not less than 15°, so that the material is not easy to enter the inner side of the connecting cavity 31.

[0027] To further explain, the width of the baffle 32 matches the width of the discharge port 2 , so that the material cannot leak out from the gap between the baffle 32 and the side wall of the discharge port 2 .

[0028] Here’s how it works:

[0029] By setting a flow regulating device 3 on the inner side of the feed hopper 1, when it is necessary to adjust and reduce the material flow rate of the discharge port 2, the hand wheel 37 is turned forward, and the hand wheel 37 drives the screw 36 to rotate through the bevel gear set 38, so that the screw 36 pushes the threaded sleeve 34 to slide downward along the slide groove 33. During this process, the baffle 32 will move synchronously with the threaded sleeve 34, so that the baffle 32 slides downward out of the connecting cavity 31 and extends into the inner side of the discharge port 2. The baffle 32 can block both sides of the discharge port 2, thereby reducing the flow rate of the discharge port 2.

[0030] When it is necessary to adjust and expand the material flow rate of the discharge port 2, reverse the hand wheel 37, let the screw 36 push the threaded sleeve 34 to slide upward along the slide groove 33, so that the baffle 32 retracts upward to the inside of the connecting cavity 31, and the baffle 32 is moved away from both sides of the discharge port 2, thereby expanding the flow rate of the discharge port 2. The caliber can be adjusted according to materials of different particle sizes to regulate the material flow rate.

[0031] The above are only preferred examples of the present invention and are not intended to limit the present invention. Although the present invention is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
