They are currently widely used in mining, metallurgy, coal, chemical, building materials, grain, and light industries. In sand and gravel production lines, they can continuously and uniformly feed crushing devices.

[0003] According to Chinese Utility Model Patent Application No. CN202421070441.4, a vibrating feeder is proposed. The utility model describes that "by setting a steering plate, the user manually turns the handle to rotate the rotating disk, which causes the positive thread rod to drive the helically connected moving block to move, so that the moving block moves relative to each other, and the position of the steering plate is adjusted so that the sliding block slides in the sliding groove opened in the steering plate. The width of the outlet is adjusted by controlling the steering plate."

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-6 The sand and gravel feeder in this embodiment includes a vibration mechanism 1, two guide blocks 2 are connected inside the vibration mechanism 1, an adjustment mechanism 3 is connected to the vibration mechanism 1, and two guide plates 4 and two positioning mechanisms 5 are connected to the adjustment mechanism 3.

[0024] Specifically, the staff can use the vibration mechanism 1 to feed sand and gravel, and use the adjustment mechanism 3 to drive the two guide plates 4 to rotate relative to each other or in opposite directions, automatically rotating the two guide plates 4 to the designated position. The operation is relatively simple. The two positioning mechanisms 5 can be used to position the two guide plates 4, and the two guide plates 4 can be manually moved to the designated position, which makes it easier to adjust the orientation of the outlet and improves the usage effect.

[0025] In this embodiment, the vibration mechanism 1 includes a chamber 11. Eight connecting rods 12 are symmetrically fixedly installed on both sides of the chamber 11. The connecting rods 12 have an L-shaped cross section. A spring 13 is fixedly installed at the bottom of the connecting rod 12. A base 14 is fixedly installed at the bottom of the spring 13. A vertical rod 15 is fixedly installed at the top of the base 14, passing through the spring 13 and extending into the connecting rod 12. A slot matching the vertical rod 15 is opened at the bottom of the connecting rod 12. Two vibration motors 16 are symmetrically fixedly installed at the bottom of the chamber 11.

[0026] Specifically, by turning on the two vibration motors 16, the two vibration motors 16 drive the chamber 11 to vibrate. The chamber 11 not only drives the spring 13 to extend and retract, but also drives the vertical rod 15 to move up and down inside the connecting rod 12.

[0027] In this embodiment, both guide blocks 2 are fixedly connected to the inner bottom wall of the compartment 11. The opposite side of the guide block 2 is in contact with the inner side wall of the compartment 11, the opposite side of the guide block 2 is an inclined surface, and the cross section of the guide block 2 is a right triangle.

[0028] Specifically, the sand and gravel move along the inner bottom wall of the silo 11, and the two guide blocks 2 guide the sand and gravel.

[0029] In this embodiment, the adjustment mechanism 3 includes two rotating shafts 31, both of which are rotatably connected to the inside of the chamber 11 via bearings. The bottom of both rotating shafts 31 extends through and to the bottom of the vibration mechanism 1. Gears 32 are fixedly installed on the outside of both rotating shafts 31. The two gears 32 mesh with each other and are the same size. A connecting plate 33 is fixedly installed on the bottom of the chamber 11, and a motor 34 is fixedly installed on the top of the connecting plate 33. The output end of the motor 34 is fixedly connected to the bottom of one of the rotating shafts 31.

[0030] Specifically, by turning on the motor 34, the motor 34 drives one of the rotating shafts 31 to rotate, one of the rotating shafts 31 drives one of the gears 32 to rotate, one of the gears 32 drives another gear 32 to rotate, and the other gear 32 drives another rotating shaft 31 to rotate.

[0031] In this embodiment, two guide plates 4 are respectively sleeved on the outside of two rotating shafts 31. Twelve limiting strips extending into the inside of the guide plates 4 are fixedly installed on the outside of the rotating shafts 31. The twelve limiting strips are evenly distributed in a ring. The inside of the guide plates 4 is provided with limiting holes that match the limiting strips.

[0032] Specifically, the guide plate 4 can be removed from the outside of the rotating shaft 31 and reattached to the outside of the rotating shaft 31.

[0033] In this embodiment, the positioning mechanism 5 includes a bolt 51, which is threadedly connected to the top of the rotating shaft 31. The top of the rotating shaft 31 has a threaded groove that matches the bolt 51. A positioning plate 52 is fixedly installed on the outside of the bolt 51. The bottom of the positioning plate 52 is in contact with the top of the guide plate 4. A knob 53 is fixedly installed on the top of the bolt 51. The knob 53 has an anti-slip groove on its outside. A protective sleeve 54 is sleeved on the outside of the knob 53. The protective sleeve 54 is made of rubber.

[0034] Specifically, first remove the protective cover 54, then turn the knob 53. The knob 53 causes the bolt 51 to unscrew from the inside of the shaft 31. The positioning plate 52 releases the top of the shaft 31. After manually adjusting the position of the shaft 31, turn the knob 53 again. The knob 53 causes the bolt 51 to screw into the inside of the shaft 31. The positioning plate 52 positions the top of the shaft 31. Finally, put the protective cover 54 on the outside of the knob 53.

[0035] The working principle of the above embodiments is as follows:

[0036] When the size of the outlet needs to be adjusted, the staff turns on the motor 34. The motor 34 drives the two rotating shafts 31, the two gears 32 and the two guide plates 4 to rotate relative to each other or in opposite directions, automatically rotating the two guide plates 4 to the designated position.

[0037] When the direction of the outlet needs to be adjusted, the staff first removes the protective cover 54, then turns the knob 53. The knob 53 causes the bolt 51 to be screwed out from the inside of the shaft 31. The positioning plate 52 releases the top of the shaft 31. After manually adjusting the position of the shaft 31, the staff turns the knob 53 again. The knob 53 causes the bolt 51 to be screwed into the inside of the shaft 31. The positioning plate 52 positions the top of the shaft 31. Finally, the protective cover 54 is put on the outside of the knob 53.

[0038] When it is necessary to feed sand and gravel, the staff turns on the two vibrating motors 16. The two vibrating motors 16 drive the bin 11 to vibrate. The bin 11 not only drives the spring 13 to extend and retract, but also drives the vertical rod 15 to move up and down inside the connecting rod 12. The sand and gravel move along the inner bottom wall of the bin 11. The two guide blocks 2 and the two guide plates 4 guide the sand and gravel.
