Upper grid bars 3 and lower grid bars 4 are bolted to the crossbeam inside the feeding box 1. At least two layers of stepped grid bars are arranged on the internal crossbeam of the feeding box 1. The grid bars have a trumpet-shaped structure, with a small inlet port and a large outlet port. The grid bars are fixed with bolts for easy replacement after wear. The spacing between the grid bars can also be adjusted according to changes in working conditions to meet the feeding and screening effects of different materials. Round pipes 5 are fixedly installed at both ends of the feeding box 1, and the two ends of the round pipes 5 are tightly connected to... The adjustable support assembly 6 includes a vibrator 7 installed in the middle of the feeding box 1, with the shaft end of the vibrator 7 connected to the motor 2 via a V-belt. The bottom of the motor 2 is equipped with a motor adjustment seat 8. The adjustable support assembly 6 is a clamp structure, with the lower clamp 603 and the upper clamp 604 fixed to the circular tube 5 of the feeding box 1. When it is necessary to change the angle of the feeder, the bolts connecting the lower clamp 603 and the upper clamp 604 are loosened, allowing the feeder to rotate and adjust around the circular tube 5. With the use of the motor adjustment seat 8, the angle of the feeding box 1 can be adjusted over a large range. The structure is simple and the adjustment operation is convenient.

[0025] The adjustable support assembly 6 includes a spring seat 601, a vibration isolation spring 602, a lower clamp 603 and an upper clamp 604. The vibration isolation spring 602 is installed on the spring seat 601, the lower clamp 603 is installed on the vibration isolation spring 602, and the upper clamp 604 is fastened to the lower clamp 603 by bolts.

[0026] The motor adjustment base 8 includes a support base plate 801, an upper fixing plate 802, a connecting rod 803, and a shock-absorbing spring 804.

One end of the connecting rod 803 is hinged to the support base plate 801 by a pin, and the other end of the connecting rod 803 is movably sleeved with the upper fixing plate 802. The shock-absorbing spring 804 is installed on the connecting rod 803.

[0027] Specifically, one end of the feeding box 1 is provided with a feed inlet 9, and a baffle 10 is provided at the feed inlet 9.

[0028] In this implementation scheme, the material is fed from the feed inlet 9, and the baffle 10 is used to prevent the material from spilling during the conveying process.

[0029] Specifically, the other end of the feeding box 1 is provided with a discharge port 11, and the lower grid bar 4 is located near the discharge port 11.

[0030] In this implementation plan, after the vibrating screen, the material is discharged from the discharge port 11.

[0031] Specifically, the upper grid bar 3 and the lower grid bar 4 have a funnel-shaped cross-section and are arranged in a stepped manner.

[0032] In this embodiment, at least two layers of stepped grid bars are installed on the internal crossbeam of the feed box 1. The grid bars have a flared structure with a small feed port and a large discharge port. The grid bars are fixed with bolts for easy replacement after wear. At the same time, the spacing between the grid bars can be adjusted according to changes in working conditions to meet the feeding and screening effects of different materials.

[0036] In this implementation plan, such as Figure 2As shown, when it is necessary to change the angle of the feeder, the motor adjustment seat 8 needs to be adjusted together with the adjustable support assembly 6. Since one end of the upper fixed plate 802 is hinged to the support base plate 801 by a pin, and the other end is supported by the connecting rod 803, it is only necessary to turn the nut on the connecting rod 803 to change the length of the connecting rod 803 on the upper fixed plate 802.

[0037] In use, the adjustable support assembly 6 is a clamp structure, fixing the lower clamp 603 and the upper clamp 604 to the circular tube 5 of the feed box 1. When it is necessary to change the angle of the feeder, loosen the bolts connecting the lower clamp 603 and the upper clamp 604, and it can be rotated around the circular tube 5 for adjustment. With the use of the motor adjustment seat 8, the angle of the feed box 1 can be adjusted over a large range. The structure is simple and the adjustment operation is convenient. At least two layers of stepped grid bars are set on the internal crossbeam of the feed box 1. The grid bars have a flared structure with a small feed port and a large discharge port.

When the angle of the feeder needs to be changed, the bolts connecting the lower clamp 603 and upper clamp 604 are loosened, allowing the feeder to rotate around the circular tube 5 for adjustment. Combined with the use of the motor adjustment seat 8, the angle of the feed box 1 can be adjusted over a wide range. The structure is simple and the adjustment operation is convenient. At least two layers of stepped grid bars are installed on the internal crossbeam of the feed box 1. The grid bars have a trumpet-shaped structure with a small inlet port and a large outlet port. The grid bars are fixed with bolts for easy replacement after wear. At the same time, the spacing between the grid bars can be adjusted according to changes in working conditions to meet the feeding and screening effects of different materials.
