[0033] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention. Embodiment 1

[0034] As Figures 1-7 shown, this embodiment discloses a two-way inertial vibrating feeder, including a connection assembly 1 for restricting the position of materials. A tightening sleeve 2 is connected to the connection assembly 1. The tightening sleeve 2 ensures the tight connection of the connection assembly 1 and improves the stability of the connection assembly 1 during use. One end of the tightening sleeve 2 is connected with a vibration damping assembly 8, and the end of the vibration damping assembly 8 away from the tightening sleeve 2 is connected with a support part 4. In this embodiment, the support part 4 is preferably an I-beam to ensure that the connection assembly 1 will not tip over when conveying materials.

[0035] The connection assembly 1 includes a protective housing 101. A vibration chamber 1011 is opened in the protective housing 101. A vibration assembly 5 is connected in the vibration chamber 1011. The materials passing through the protective housing 101 will enter the vibration chamber 1011 and fall on the vibration assembly 5. The vibration of the vibration assembly 5 drives the materials on its surface to move evenly, realizing the movement of the materials. To ensure that the vibration assembly 5 completes the movement of the materials, a power assembly 3 is connected to the vibration assembly 5. A plurality of vibrators 6 are connected to the vibration assembly 5. The end of the vibrator 6 away from the vibration assembly 5 is connected to the wall of the vibration chamber 1011. The power assembly 3 drives the vibration assembly 5 to move, and the vibrator 6 is used to maintain the vibration direction to ensure the normal movement of the materials on the surface of the vibration assembly 5.

[0036] When the bidirectional inertial vibrating feeder is in use, the material to be transported passes through the protective shell 101 and enters the vibration chamber 1011, and falls on the vibration component 5. At this time, the power component 3 and the exciter 6 are controlled to work, driving the vibration component 5 to vibrate, so as to move the material on the vibration component 5. In the process of vibration of the vibration component 5, the connection component 1 will be vibrated, and the vibration frequency of the connection component 1 will be weakened by the vibration reduction component 8 to ensure that the connection component 1 will not shake significantly, thereby ensuring its safety in use.

[0037] In order to ensure the safety of the vibration component 5 when in use and improve the use efficiency of the vibration component 5, two working components 7 for identifying and detecting the conveying status of the vibration component 5 are provided on the vibration component 5. The working components 7 include a connecting plate 701. The two ends of the connecting plate 701 distributed along the length direction are rotatably connected in the vibration cavity 1011. A plurality of connecting columns 702 are connected to one end of the connecting plate 701 close to the vibration component 5. A movable rod 703 is slidably provided at one end of the connecting column 702 away from the connecting plate 701. A resistance rod 7031 is connected to the movable rod 703, and the resistance rod 7031 can resist the vibration component 5.

[0038] Furthermore, the vibration assembly 5 includes a vibration plate 501, wherein the length direction of the connecting plate 701 corresponds to the width direction of the vibration plate 501, the exciters 6 are connected to the vibration plate 501, and the two ends of the vibration plate 501 distributed along the length direction are respectively provided with screening grooves 502 for improving the material transmission efficiency. When the material vibrates on the vibration plate 501 and moves to the area of the screening groove 502, part of the material will directly fall through the screening groove 502, and another part will fall after being transmitted to the end of the screening groove 502 as the vibration of the vibration plate 501, thereby realizing batch conveying of the material, ensuring the material conveying efficiency while effectively reducing the accumulation of the material. The movable rod 703 is located at the screening groove 502, and the movable rod 703 always runs through the screening groove 502.

[0039] Furthermore, the protective shell 101 is respectively penetrated by a feed port 102 and two discharge ports 103, wherein the feed port 102 and the discharge port 103 are respectively located on both sides of the vibration plate 501 along the thickness direction, and the two discharge ports 103 are respectively distributed along the length direction of the protective shell 101, and the material to be transported enters the vibration cavity 1011 through the feed port 102, and as the vibration of the vibration plate 501 is transmitted, the material is moved out of the vibration cavity 1011 through the two discharge ports 103.

[0040] In order to ensure that the material does not separate from the vibrating plate 501 during the process of conveying the material, further, the surface of the vibrating plate 501 is in an arc shape, and the distribution of the plurality of movable rods 703 is the same as the radian of the vibrating plate 501, that is, the height of the movable rods 703 passing through each area of the vibrating plate 501 is the same.

[0041] In order to ensure that the power assembly 3 can perform bidirectional vibrating feeding on the vibrating plate 501, further, the power assembly 3 includes a first vibrating motor 301. The first vibrating motor 301 is located on one side of the feeding port 102. A second vibrating motor 302 and a third vibrating motor 303 are respectively connected between the two discharging ports 103. The first vibrating motor 301, the second vibrating motor 302, and the third vibrating motor 303 can all act on the vibrating plate 501. At the same time, the rotation directions of the second vibrating motor 302 and the third vibrating motor 303 are the same, and the rotation direction of the first vibrating motor 301 is opposite to that of the second vibrating motor 302 and the third vibrating motor 303. Through the three vibrating motors arranged in a triangular pattern, periodic vibration is performed to adjust the composite vibration, realizing the bidirectional conveying of the material on the vibrating plate 501, which has the characteristics of high efficiency and high stability. In this embodiment, the first vibrating motor 301, the second vibrating motor 302, and the third vibrating motor 303 are all prior arts and will not be elaborated here.

[0042] Further, an activity groove is provided on one side of the movable rod 703 close to the connecting column 702. One end of the movable rod 703 close to the connecting column 702 is connected with a return spring 704. The return spring 704 is located in the activity groove. One end of the return spring 704 away from the movable rod 703 is connected with the connecting column 702. When the abutting rod 7031 is abutted by the vibrating plate 501, at this time, according to the pressure borne on the vibrating plate 501, the movable rod 703 can be compressed and drive the return spring 704 to be compressed.

[0043] When the vibrating plate 501 is vibrating and conveying materials, since the vibrating plate 501 and the abutting rod 7031 are in mutual contact, the movable rod 703 will be in the same-frequency moving state as the vibrating plate 501, that is, under the vibrating state of the vibrating plate 501, the return spring 704 can expand and contract along with the vibrating plate 501, so as to identify the material condition on the vibrating plate 501 and the vibrating condition of the vibrating plate 501, ensuring that the working state of the vibrating plate 501 is always in a stable state.

[0044] When the vibrating plate 501 is in a normal working state, the weight of the material on the vibrating plate 501 can be identified by using the return spring 704. When the compression depth of the return spring 704 is in the normal compression depth, it means that the vibrating plate 501 is in a normal working state at this time, and the vibration state of the vibrating plate 501 is maintained stable. When the compression depth of the return spring 704 is relatively deep, it means that the weight of the material on the vibrating plate 501 is relatively heavy at this time, which affects the feeding state of the vibrating plate 501. At this time, the vibration frequency of the vibrating plate 501 needs to be adjusted.

[0045] When both the vibration frequency and the compression depth of the return spring 704 are in a normal state, it means that the vibration condition of the vibrating plate 501 is in a normal working state at this time. When the vibration frequency of the return spring 704 is normal, but the compression depth is relatively deep, it means that the vibration state of the vibrating plate 501 is stable at this time, but there is more material stored on the vibrating plate 501, warning the staff to slow down the feeding rate of the feeding port 102.

[0046] Furthermore, in order to ensure that during the process of the contact rod 7031 being contacted by the vibrating plate 501, relative sliding can occur between the contact rod 7031 and the vibrating plate 501 through the active rotation of the connecting plate 701, the contact rod 7031 is cylindrical, and a groove for restricting the position of the contact rod 7031 is provided on the connecting column 702, ensuring that when the contact rod 7031 expands and contracts with the return spring 704 on the connecting column 702, the moving state of the contact rod 7031 is stable.

[0047] It should be noted that in order to ensure that the return spring 704 can effectively identify the working state of the vibrating plate 501, a pressure sensor is provided at one end of the return spring 704, and the elastic change of the return spring 704 is identified through the change of the pressure indication of the pressure sensor, ensuring that the working state of the vibration assembly 5 can be identified by using the return spring 704.

[0048] When the device is working, the power assembly 3 is controlled to work, prompting the vibrating plate 501 to vibrate, and then the vibrator 6 is used to maintain the stable vibration state of the vibrating plate 501, so as to ensure that the vibrating plate 501 is in a normal vibration state.

[0049] The material to be conveyed enters the vibration cavity 1011 through the feeding port 102 and lands on the vibration assembly 5, thereby realizing the conveyance and separation of the material. Specifically, when the material lands on the vibrating plate 501, the vibration of the vibrating plate 501 is used to move the material to one side close to the screening slot 502, so that the material moves through the screening slot 502 to the discharge port 103, realizing the replenishment of the material.

[0050] When the vibrating plate 501 is in a normal working state, the movable rod 703 vibrates along with the vibration frequency of the vibrating plate 501. When the material passes through the screening trough 502, some of the material will directly fall to the discharge port 103 through the screening trough 502, and the remaining material will move to the end of the vibrating plate 501 through the movable rod 703 and enter the discharge port 103 along with the vibration of the vibrating plate 501. During the movement towards the end, the material also continuously passes through the screening trough 502 and separates from the vibrating plate 501. In order to ensure the stable feeding rate of the vibrating feeder during feeding, the replenishment rate of the material on the vibrating plate 501 is adjusted by using the movable rod 703, that is, when the material passes through the movable rod 703, the excess material can be blocked by the movable rod 703 or the material passing through the screening trough 502 can be accelerated to ensure the stable discharge rate through the discharge port 103.

[0051] And in order to judge the working state of the vibration assembly 5, during the use process, the state of the vibration assembly 5 is identified by recognizing the working state of the return spring 704. When the return spring 704 is in a normal compression depth and the compression frequency is in a normal state, it means that the vibrating plate 501 is in a normal working state at this time, and the power assembly 3 and the vibrator 6 are both in a stable working mode, ensuring that the discharge port 103 is in a normal replenishment progress.

[0052] When the return spring 704 is in a normal compression depth but its compression frequency is in an abnormal state, this means that the feeding rate on the vibrating plate 501 is stable and in a normal state at this time, but the power assembly 3 and the vibrator 6 have working faults, affecting the vibration amplitude of the vibrating plate 501, thus interfering with the replenishment rate of the material, resulting in an abnormal reading of the pressure sensor on the return spring 704, prompting the staff to detect the working performance of the power assembly 3 and the vibrator 6 to ensure that the double - inertial vibrator is in a normal conveying state.

[0053] When the return spring 704 is in a normal compression frequency but the compression depth increases, it means that the periodic telescopic change of the return spring 704 is in a normal state, representing that the working states of the power assembly 3 and the vibrator 6 are stable, which can ensure that the vibrating plate 501 vibrates and conveys the material above it. However, due to the increase in the compression depth of the return spring 704, when ensuring that the vibration assembly 5 is in a normal working state, it means that the amount of material falling onto the vibrating plate 501 through the feed port 102 increases at this time, causing an increase in the gravity on the vibrating plate 501.

[0054] When the compression depth of the return spring 704 increases and remains constant, at this time, according to the pressure indication of the pressure sensor, the vibration amplitudes of the power assembly 3 and the vibrator 6 are increased to improve the vibration amplitude of the vibrating plate 501, ensuring the stable conveyance of the material on the vibrating plate 501; when the compression depth of the return spring 704 is in the stage of gradually deepening, initially, the vibration amplitudes of the power assembly 3 and the vibrator 6 are adjusted. When the return spring 704 continues to be compressed, the operation of the power assembly 3 and the vibrator 6 is interrupted, causing the vibrating plate 501 to stop vibrating, and prompting the staff to inspect the feed inlet 102. On the one hand, it ensures the stable feeding rate, and on the other hand, it avoids excessive pressure on the vibrating plate 501 from damaging the power assembly 3 and the vibrator 6, ensuring the constant service life of the vibrating feeder.

[0055] After inspection by the staff, when the feed inlet 102, the power assembly 3, and the vibrator 6 are all in the normal working mode, but the compression amplitude of the return spring 704 and the indication of the pressure sensor continue to increase, it means that the screening tank 502 is blocked with materials at this time. While maintaining the normal operation of the power assembly 3 and the vibrator 6, the connecting plate 701 is controlled to rotate in the vibration cavity 1011, thereby realizing the rotation of the connecting column 702 and the movable rod 703. And since the abutting rod 7031 is cylindrical and always abuts against the vibrating plate 501, during the rotation of the connecting plate 701, due to the elastic action of the return spring 704, the lengths of the connecting column 702 and the movable rod 703 will be extended, causing the movable rod 703 to move in the screening tank 502 to clean the blockage in the screening tank 502. And when there is a blockage in the screening tank 502, the elastic action of the power assembly 3, the vibrator 6, and the return spring 704 is utilized to clean the impurities in the screening tank 502, that is, when the vibrating plate 501 vibrates, it drives the abutting rod 7031 to move, so that the contact pressure between the movable rod 703 and the impurities in the screening tank 502 is always in a dynamically changing process, thereby cleaning the blockage in the screening tank 502 and ensuring the normal conveying state of the vibrating plate 501. Embodiment 2

[0059] S3. When the material is conveyed to one side of the screening tank 502 on the vibrating plate 501, the material falls from the vibrating plate 501 through the screening tank 502 in sequence;

[0060] S4. Use the movable rod 703 to comb the material passing through the screening tank 502 to ensure the stable conveyance of the material passing through the screening tank 502.

[0061] S5. The material passing through the screening tank 502 passes through the discharge port 103 in sequence and then is discharged from the vibration cavity 1011, completing the feeding of the material.

When the material is conveyed on the vibration plate (501) to one side of the screening trough (502), the material falls from the vibration plate (501) in sequence through the screening trough (502); S4. Use the movable rod (703) to comb the material passing through the screening trough (502) to ensure the stable conveyance of the material passing through the screening trough (502). At the same time, use the movable rod (703) to identify the working state of the return spring (704) during vibration, so as to ensure the stable vibration state of the vibration plate (501); S5. The material after passing through the screening trough (502) passes through the discharge outlet (103) in sequence and then is discharged from the vibration cavity (1011), completing the feeding of the material.
