[0022] The technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0023] like Figures 1 to 4 As shown, an embodiment of the present invention proposes a vibrating feeding device for inputting materials from a storage bin into a receiving device, and coarsely screening the materials during the feeding process for the receiving device.

[0024] Please refer to Figure 1 and Figure 2The vibrating feeding device comprises a base 1 and a main body 2 floatingly arranged on the base 1, wherein a vibrating motor 3 is arranged on the main body 2 and used to drive the main body 2 to vibrate on the base 1. The main body 2 is provided with a feeding groove 21 with an open end, wherein a fixed grid plate 4 and a movable grid plate 5 are arranged in the feeding groove 21, a driving assembly 6 is arranged on the main body 2 and in transmission connection with the movable grid plate 5, the driving assembly 6 is used to drive the movable grid plate 5 to move close to or away from the fixed grid plate 4, the fixed grid plate 4 is arranged close to the opening of the feeding groove 21, a plurality of first grid strips 41 are arranged on the fixed grid plate 4 in intervals and two adjacent first grid strips 41 enclose a dropping groove 42, the width of the dropping groove 42 gradually increases along the vertical direction, a plurality of second grid strips 51 are arranged on the movable grid plate 5 in intervals and in one-to-one alignment with the dropping grooves 42 and respectively extend into the dropping grooves 42, the width of the second grid strips 51 gradually increases along the vertical direction and the second grid strips 51 and the first grid strips 41 enclose a dropping passage 52 in communication with the dropping grooves 42, after the material is poured into the feeding groove 21, the material is driven by the vibrating motor 3 to vibrate the main body 2 and move along the feeding groove 21 to the fixed grid plate 4 and enter the dropping grooves 42, when the particle size of the material is smaller than the width of the dropping passage 52, the material falls along the dropping passage 52 to the lower side of the movable grid plate 5, when the particle size of the material is larger than the width of the dropping passage 52, the material continues to move along the feeding groove 21 until it is discharged from the opening of the feeding groove 21, so as to realize the coarse screening of the material and input the material into a receiving device; when the driving assembly 6 drives the movable grid plate 5 to move close to the fixed grid plate 4, the second grid strips 51 extend into the dropping grooves 42, so that the width of the dropping passage 52 gradually decreases, and when the driving assembly 6 drives the movable grid plate 5 to move away from the fixed grid plate 4, the second grid strips 51 exit the dropping grooves 42, so that the width of the dropping passage 52 gradually increases, that is, the size of the material screened out in the coarse screening process of the vibrating feeding device can be adjusted by moving the movable grid plate 5 through the driving assembly 6.

[0025] Specifically, the operating steps for feeding using the vibrating feeding device provided in this embodiment are as follows: connecting the opening of the feeding trough 21 with the feeding end of the receiving device, then starting the vibration motor 3 and pouring the material into the feeding trough 21, the main body 2 vibrates on the base 1 under the drive of the vibration motor 3 to move the material along the feeding trough 21, and when the material moves to the fixed grid plate 4, it falls into the dropping trough 42. When the particle size of the material is smaller than the width of the dropping channel 52, the material will fall along the dropping channel 52 to the bottom of the movable grid plate 5, thereby separating the material with too small a particle size, and the material with a particle size larger than the width of the dropping channel 52 will continue to move along the feeding trough 21. The screened material is discharged from the opening of the feeding trough 21 and enters the receiving equipment, thereby realizing the coarse screening and feeding of the material. When the vibrating feeding device provided in this embodiment is used to coarsely screen materials of different sizes, the driving assembly 6 drives the movable grid plate 5 to move on the main body 2. When the movable grid plate 5 approaches the fixed grid plate 4, the second grid bar 51 extends into the drop chute 42. At this time, the width of the drop channel 52 is reduced. When the movable grid plate 5 moves away from the fixed grid plate 4, the second grid bar 51 exits the drop chute 42, increasing the width of the drop channel 52. That is, the width of the drop channel 52 can be adjusted by moving the movable grid plate 5, thereby changing the particle size of the material that can pass through the drop channel 52 to meet the needs of screening materials of different sizes. The vibrating feeding device provided in this embodiment can conveniently adjust the screening size, and no parts need to be replaced during the adjustment process. The adjustment operation is simple, which helps to reduce equipment costs.

[0026] like Figure 1 As shown, in this embodiment, a support spring 11 is provided on the base 1, and one end of the support spring 11 away from the base 1 abuts against the main body 2. By providing the support spring 11 on the base 1 to support the main body 2, the main body 2 can move relative to the base 1. When the vibration motor 3 drives the main body 2 to vibrate, the support spring 11 expands and contracts with the vibration of the main body 2, thereby maintaining a stable position of the main body 2 on the base 1.

[0027] Please combine Figure 1 and Figure 3 The main body 2 is further provided with a material guide plate 22, which is arranged around the opening of the feed trough 21 and extends away from the main body 2. The material guide plate 22 is used to guide the material discharged from the opening of the feed trough 21 to the feeding end of the material receiving device, ensuring that the material can be smoothly fed into the material receiving device and preventing the material from falling outside the material receiving device during the feeding process and causing loss.

[0028] In detail, the main body 2 is further provided with a material receiving plate 23 located below the movable grating plate 5 and extending in a direction opposite to the extending direction of the material guide plate 22. The material receiving plate 23 arranged below the movable grating plate 5 is used to receive the material falling after coarse screening and guide the material to move in a direction opposite to the opening of the feeding chute 21, so as to collect the screened material and avoid the screened material mixing with the material discharged from the opening of the feeding chute 21 again.

[0029] As shown in Figure 3 and Figure 4 , the driving assembly 6 comprises a fixed seat 61 arranged on the main body 2 and provided with a threaded rod 62, the axial direction of the threaded rod 62 is consistent with the moving direction of the movable grating plate 5, the threaded rod 62 is provided with two locking nuts 63 respectively matched with the threaded rod 62, the movable grating plate 5 is provided with a movable seat 53, the movable seat 53 is provided with a through hole 54 through which the threaded rod 62 passes, and the two locking nuts 63 respectively abut against the opposite sides of the movable seat 53. By rotating the locking nuts 63, the locking nuts 63 can be moved on the threaded rod 62, thereby enabling the movable seat 53 to slide along the axial direction of the threaded rod and drive the movable grating plate 5 to move, so that the movable grating plate 5 approaches or moves away from the fixed grating plate 4, and after adjusting the movable grating plate 5 to the position, rotating the locking nuts 63 clamps the movable seat 53 between the two locking nuts 63, that is, the position of the movable grating plate 5 on the main body 2 can be locked, preventing the movable grating plate 5 from moving unexpectedly due to the collision between the material and the movable grating plate 5 during screening, and facilitating to improve the reliability of the vibrating feeding device.

[0030] Specifically, the movable seat 53 is provided with a protruding guide rod 55, the main body 2 is provided with a guide groove 24 through which the guide rod 55 passes, and the length direction of the guide groove 24 is consistent with the moving direction of the movable grating plate 5. The guide groove 24 is arranged on the main body 2 and matched with the guide rod 55 on the movable seat 53, when the movable grating plate 5 moves on the main body 2, the guide rod 55 slides in the guide groove 24, avoiding the movable grating plate 5 from deviating from the preset direction when moving.

[0031] Please refer to Figure 4The first mounting hole is coaxial with the guide rod 55, and the first threaded hole is aligned with the first mounting hole, and the first connecting bolt 56 is arranged in the first mounting hole and matched with the first threaded hole.

[0032] As shown in Figure 1 The second threaded hole is arranged on the main body 2, and the second mounting hole is arranged on the fixed grid plate 4 and aligned with the second threaded hole, and the second connecting bolt is arranged in the second mounting hole and matched with the second threaded hole. The second wheel connecting bolt is matched with the second threaded hole on the main body 2 through the second mounting hole on the fixed grid plate 4, so that the fixed grid plate 4 is installed on the main body 2, and the position of the fixed grid plate 4 on the main body 2 is kept stable, which is beneficial to improve the structural stability of the vibrating feeder.

[0033] As shown in Figure 4 The second grid bar 51 is provided with a hollow groove 57, and the hollow groove 57 is located on the side of the second grid bar 51 away from the material falling groove 42. The hollow groove 57 arranged on the second grid bar 51 is used to reduce the overall weight of the movable grid plate 5, so as to facilitate the adjustment of the position of the movable grid plate 5.

[0034] Please refer to Figure 1 The main body 2 is provided with a mounting seat away from the feeding groove 21, and the vibrating motor 3 is arranged on the mounting seat. The mounting seat is arranged on the main body 2 for mounting the vibrating motor 3, so that the vibrating motor 3 is matched with the main body 2 firmly, and the main body 2 is continuously and stably vibrated under the driving of the vibrating motor 3.
