Description

Technical Field

[0001] This application relates to the field of material handling technology, and in particular to a vibrating feeder. Background Technology

[0002] A vibrating feeder, also known as a vibrating conveyor, is a device that can uniformly, regularly, and continuously feed lumpy or granular materials from a storage silo to a receiving device. The vibrating feeder utilizes the centrifugal force generated by the rotation of an eccentric block in the vibrator to force the moving parts, such as the screen box and vibrator, to perform a forced, continuous circular or near-circular motion. A vibrating feeder consists of a feeding trough, a vibrator, spring supports, and a transmission device. The vibration source for the trough vibrating feeder is the vibrator, which consists of two eccentric shafts (active and passive) and a gear pair. An electric motor drives the active shaft via a V-belt, and the gear on the active shaft meshes with the passive shaft to rotate. The active and passive shafts rotate simultaneously in opposite directions, causing the trough to vibrate and ensuring a continuous flow of material, thus achieving the purpose of material conveying.

[0003] However, existing vibrating feeders usually only have one feeding trough, so they can only deliver one type of material when conveying materials. If different materials need to be delivered to two devices at the same time, the number of feeders needs to be increased. This will not only increase the production cost of enterprises, but also make the space occupied by the equipment in the production area larger. Utility Model Content

[0004] This application provides a vibrating feeder that can simultaneously transport two different materials in a single device, thereby reducing enterprise production costs and minimizing the space required in the production area.

[0005] The above-mentioned objective of this application is achieved through the following technical solution:

[0006] A vibrating feeder includes a base housing on which a vibrator is mounted on the outside. The bottom of the base housing is mounted on a spring support. The interior of the base housing is provided with an upper feeding trough and a lower feeding trough in a vertical direction from top to bottom, and there is a gap between the upper feeding trough and the lower feeding trough.

[0007] The upper feeding trough and the lower feeding trough are both inclined in the same direction within the base shell, and there is a gap between the upper end of the upper feeding trough and the end plate on the same side of the base shell;

[0008] The upper feeding trough is mounted on the base housing via a first adjustment component on each side of its width direction, and the lower feeding trough is mounted on the base housing via a second adjustment component on each side of its width direction. The tilt angle of the upper feeding trough can be adjusted via the first adjustment component, and the tilt angle of the lower feeding trough can be adjusted via the second adjustment component.

[0009] Furthermore, there is a gap between the lower side of the lower feed trough and the bottom plate of the base shell, as well as between the upper end of the lower feed trough and the end plate of the base shell on the adjacent side; an inclined guide plate is provided between the upper end of the lower feed trough and the upper end of the upper feed trough, the upper end of the guide plate is fixedly connected to the end plate of the base shell on the adjacent side, and the lower end of the guide plate extends downward to above the upper end of the lower feed trough.

[0010] Furthermore, the projection of the lower end of the upper feed trough onto the horizontal plane is located outside the projection of the lower feed trough onto the horizontal plane.

[0011] Furthermore, the first adjustment component includes a first adjustment hole, a second adjustment hole, and a third adjustment hole. The first adjustment hole, the second adjustment hole, and the third adjustment hole are evenly arranged on one side wall of the base housing along the length direction. A first bolt is inserted at a position corresponding to the first adjustment hole, the second adjustment hole, and the third adjustment hole on the upper feeding groove. The nut end of the first bolt is located inside the upper feeding groove. The threaded section of the first bolt extends from the inside to the outside of the upper feeding groove, passing through the corresponding first adjustment hole, the second adjustment hole, or the third adjustment hole, and then to the outside of the base housing. The portion of the first bolt located outside the base housing is fitted with a first nut, and the two are threadedly connected.

[0012] Furthermore, the second adjustment component includes a fourth adjustment hole and a fifth adjustment hole. The fourth adjustment hole and the fifth adjustment hole are evenly arranged below the first adjustment hole, the second adjustment hole and the third adjustment hole along the length direction of the base shell. A second bolt is inserted at a position on the lower feed trough corresponding to the fourth adjustment hole and the fifth adjustment hole. The nut end of the second bolt is located inside the lower feed trough. The threaded section of the second bolt extends from the inside to the outside of the lower feed trough, passing through the corresponding fourth adjustment hole or the fifth adjustment hole and extending to the outside of the base shell. The portion of the second bolt located on the outside of the base shell is fitted with a second nut, and the two are threadedly connected.

[0013] Furthermore, both sides of the upper end of the upper feed trough and the lower feed trough in the width direction are movably connected to the base shell through a rotating unit.

[0014] Furthermore, the rotating unit includes a mounting block installed on the outer side of the upper end of the upper or lower feeding trough, a rotating shaft passing through the mounting block and rotatably connected to it, and one end of the rotating shaft being fixedly connected to the side wall of the base shell adjacent to it.

[0015] Furthermore, the first adjustment hole, the second adjustment hole, the third adjustment hole, the fourth adjustment hole, and the fifth adjustment hole are all arc-shaped through holes. The centers of the first adjustment hole, the second adjustment hole, and the third adjustment hole are located on the axis of the rotating shaft on the upper feed trough, and the centers of the fourth adjustment hole and the fifth adjustment hole are both located on the axis of the rotating shaft on the lower feed trough.

[0016] The distances between the first adjusting hole, the second adjusting hole, and the third adjusting hole on the upper feeding trough and the rotating shaft on the upper feeding trough increase sequentially. The length of the first adjusting hole is less than the length of the second adjusting hole, and the length of the second adjusting hole is less than the length of the third adjusting hole.

[0017] The distance between the fourth adjustment hole and the fifth adjustment hole on the lower feed trough and the rotating shaft on the upper feed trough increases sequentially, and the length of the fourth adjustment hole is less than the length of the fifth adjustment hole.

[0018] Furthermore, two of the first bolts and the first nut are installed in the third adjustment hole, and two of the second bolts and the second nut are installed in the fifth adjustment hole.

[0019] In summary, this application includes at least one of the following beneficial technical effects:

[0020] This application features an upper feed chute and a lower feed chute mounted on a base housing equipped with a vibrator. During use, the base housing vibrates due to the vibrator, allowing the upper and lower feed chutes to transport two different materials to different locations using this vibration. Compared to existing technologies, this vibrating feeder can achieve the transmission of two different materials with a single device. Since the upper and lower feed chutes are arranged vertically and mounted on the same base housing, sharing the same vibrator, they not only minimize the required production area but also effectively reduce production costs. The application includes a first adjustment component on the upper feed chute and a second adjustment component on the lower feed chute. During use, their tilt angles can be adjusted according to the material or particle size of the transported material to ensure the material slides to the designated area at an ideal speed. This improves the applicability and flexibility of the vibrating feeder. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are also within the scope of protection of this application.

[0027] like Figure 1 and Figure 2As shown, a vibrating feeder disclosed in this application includes a base housing 1 with a vibrator mounted on its outer side. The bottom of the base housing 1 is mounted on a spring support 2. An upper feed trough 3 and a lower feed trough 4 are arranged vertically from top to bottom inside the base housing 1, with a gap between them. The upper feed trough 3 and the lower feed trough 4 are both inclined in the same direction inside the base housing 1, and there is a gap between the upper end of the upper feed trough 3 and the end plate on the same side of the base housing 1. The two sides of the upper feed trough 3 in the width direction are respectively mounted on the base housing 1 by a first adjusting component 5, and the two sides of the lower feed trough 4 in the width direction are respectively mounted on the base housing 1 by a second adjusting component 6. The inclination angle of the upper feed trough 3 can be adjusted by the first adjusting component 5, and the inclination angle of the lower feed trough 4 can be adjusted by the second adjusting component 6.

[0028] In the above embodiments, the upper feed trough 3 and lower feed trough 4, which are vertically arranged within the base shell 1, need to transport different materials during use. The gap between the upper feed trough 3 and lower feed trough 4 ensures that the lower feed trough 4 is not affected by the upper feed trough 3 when transporting materials. Both the upper feed trough 3 and lower feed trough 4 are inclined to facilitate the smooth movement of materials along their length under their own weight when they vibrate together with the base shell 1. The gap between the upper end of the upper feed trough 3 and the end plate of the base shell 1 facilitates the transfer of materials to be transported by the lower feed trough 4 through the upper feed trough 3 onto the lower feed trough 4.

[0029] The vibrating feeder of this application can feed two different materials onto the upper feed trough 3 and the lower feed trough 4 respectively. Since both the upper feed trough 3 and the lower feed trough 4 are mounted on a base housing 1 equipped with a vibrator, when the base housing 1 vibrates during use (in actual production, the motor driving the vibrator can preferably be a variable frequency speed control motor, so that the feeding amount can be controlled by adjusting the motor frequency), the upper feed trough 3 and the lower feed trough 4 can vibrate synchronously with the base housing 1, and use this vibration to transport the two different materials to different locations or equipment. Compared with the prior art, the vibrating feeder of this application can achieve the transmission effect of two different materials with a single device. Since the upper feed trough 3 and the lower feed trough 4 are arranged vertically in sequence and are mounted on the same base housing 1 sharing the same set of vibrators, not only does it not occupy too much production area during use, but it also effectively reduces production costs. The first adjusting component 5, which is respectively installed on the upper feeding trough 3, and the second adjusting component 6, which is installed on the lower feeding trough 4, can adjust their tilt angles in a timely manner according to the different materials or particle sizes of the conveyed materials during use, so as to ensure that the materials slide to the designated area at the ideal speed. This can improve the applicability and flexibility of the vibrating feeder of this application.

[0030] Furthermore, such as Figure 1 and Figure 2 As shown, there are gaps between the lower side of the lower feed trough 4 and the bottom plate of the base shell 1, as well as between the upper end of the lower feed trough 4 and the end plate of the base shell 1 on the adjacent side; an inclined guide plate 7 is provided between the upper end of the lower feed trough 4 and the upper end of the upper feed trough 3. The upper end of the guide plate 7 is fixedly connected to the end plate of the base shell 1 on the adjacent side, and the lower end of the guide plate 7 extends downward to above the upper end of the lower feed trough 4.

[0031] In the above embodiments, the lower feeding trough 4 of this application may need to adjust its tilt angle according to the different materials being transported. The gap between the upper feeding trough 3 and the lower feeding trough 4 not only allows the lower feeding trough 4 to smoothly transport materials, but also meets the space requirements for adjusting the tilt angle when the upper feeding trough 3 rotates downward and the lower feeding trough 4 rotates upward. Correspondingly, the interval between the lower side of the lower feeding trough 4 and the bottom plate of the base shell 1 meets the space requirements when the lower feeding trough 4 rotates downward. When feeding materials into the lower feeding trough 4 of this application, it mainly relies on the gap between the upper feeding trough 3 and the end plate of the base shell 1. However, with the adjustment of the angle of the lower feeding trough 4, its upper end may be blocked by the upper feeding trough 3 or other situations may affect the feeding of materials. Therefore, this application sets a guide plate 7 between the upper feeding trough 3 and the lower feeding trough 4 in the manner described above, and the guide plate 7 and the upper end of the lower feeding trough 4 have a certain overlap area. This ensures that after the angle of the lower feeding trough 4 is adjusted, the guide plate 7 can always smoothly feed materials onto the lower feeding trough 4.

[0032] Furthermore, such as Figure 1 and Figure 2 As shown, the projection of the lower end of the upper feed trough 3 onto the horizontal plane is located outside the projection of the lower feed trough 4 onto the horizontal plane.

[0033] In the above embodiments, the projection of the lower end of the upper feeding trough 3 on the horizontal plane is located outside the projection of the lower feeding trough 4 on the horizontal plane (the side away from the base shell 1 of this invention is the outer side). In this way, the discharge position of the material conveyed by the upper feeding trough 3 and the discharge position of the material conveyed by the lower feeding trough 4 can be staggered, which facilitates the addition of materials to different devices that are not in the same position on the horizontal plane.

[0034] Furthermore, such as Figure 1 and Figure 2As shown, the first adjustment component 5 includes a first adjustment hole 51, a second adjustment hole 52, and a third adjustment hole 53. The first adjustment hole 51, the second adjustment hole 52, and the third adjustment hole 53 are evenly arranged on one side wall of the base housing 1 along its length direction. A first bolt 54 is inserted at a position on the upper feeding groove 3 corresponding to the first adjustment hole 51, the second adjustment hole 52, and the third adjustment hole 53. The nut end of the first bolt 54 is located inside the upper feeding groove 3. The threaded section of the first bolt 54 extends from the inside to the outside through the corresponding first adjustment hole 51, the second adjustment hole 52, or the third adjustment hole 53 from the side wall of the upper feeding groove 3 to the outside of the base housing 1. A first nut 55 is fitted on the part of the first bolt 54 located outside the base housing 1, and the two are threadedly connected.

[0035] In the above embodiments, a first bolt 54 is inserted at each position corresponding to the first adjustment hole 51, the second adjustment hole 52, and the third adjustment hole 53 on the upper feed trough 3 and the base housing 1. Thus, when fixing the upper feed trough 3 and the base housing 1 together, simply insert the threaded sections of the three first bolts 54 on the upper feed trough 3 into the corresponding first adjustment holes 51, 52, and 53, respectively, and then screw on the threaded sections of the three first bolts 54 on the outside of the base housing 1 using first nuts 55 that match their specifications. Since the upper feed trough 3 will vibrate during use, to reduce the risk of the first bolts 54 and first nuts 55 loosening, anti-slip washers (or anti-loosening washers) can be added between the nut of the first bolt 54 and the base housing 1, and between the first nut 55 and the base housing 1. This can effectively improve the stability of the installed upper feed trough 3 during use. When technicians need to adjust the tilt angle of the upper feed trough 3, they can loosen the first nut 55 of the first bolt 54 on the upper feed trough 3 in sequence, and then tighten all the first nuts 55 again after rotating the upper feed trough 3 in the base housing 1. This makes the adjustment of the angle of the upper feed trough 3 simple and convenient.

[0036] Furthermore, such as Figure 1 and Figure 2 As shown, the second adjustment component 6 includes a fourth adjustment hole 61 and a fifth adjustment hole 62. The fourth adjustment hole 61 and the fifth adjustment hole 62 are evenly arranged below the first adjustment hole 51, the second adjustment hole 52 and the third adjustment hole 53 along the length direction of the base shell 1. A second bolt 63 is inserted at the position corresponding to the fourth adjustment hole 61 and the fifth adjustment hole 62 on the lower feed trough 4. The nut end of the second bolt 63 is located inside the lower feed trough 4. The threaded section of the second bolt 63 extends from the inside to the outside from the side wall of the lower feed trough 4 through the corresponding fourth adjustment hole 61 or fifth adjustment hole 62 and extends to the outside of the base shell 1. The part of the second bolt 63 located outside the base shell 1 is fitted with a second nut 64 and the two are threadedly connected.

[0037] In the above embodiments, since the portion of the upper feeding trough 3 extending out of the base housing 1 is longer than that of the lower feeding trough 4, in order to ensure the stability of the upper feeding trough 3 during use, three fixed areas (i.e., the positions of the first adjustment hole 51, the second adjustment hole 52, and the third adjustment hole 63) are provided in the contact area between the upper feeding trough 3 and the base housing 1 on each side in the width direction. Since the contact area between the lower feeding trough 4 and the base housing 1 is large, the friction force between them after contact is also relatively large. Therefore, two fixed areas (i.e., the positions of the fourth adjustment hole 61 and the fifth adjustment hole 62) are provided in the contact area between the lower feeding trough 4 and the base housing 1 on each side in the width direction. When it is necessary to fix the lower feed trough 4 and the base shell 1 together, the lower feed trough 4 is fastened to the corresponding positions of the fourth adjustment hole 61 and the fifth adjustment hole 62 using the second nut 64 and the second bolt 63. When it is necessary to adjust the angle of the lower feed trough 4, the second nut 64 is loosened, the angle of the lower feed trough 4 is adjusted, and then the second nut 64 is tightened again. This makes the angle adjustment of the lower feed trough 4 simple and convenient to operate. Similar to the first bolt 54 and the first nut 55, in order to reduce the risk of the second bolt 63 and the second nut 64 loosening during use, an anti-slip shim (or anti-loosening shim) can be added between them.

[0038] Furthermore, such as Figure 2 and Figure 3 As shown, the upper feed trough 3 and the lower feed trough 4 are movably connected to the base shell 1 on both sides of the upper width direction through a rotating unit 8.

[0039] In the above embodiments, when adjusting the angle of the upper feed trough 3 or the lower feed trough 4, the upper position of these troughs is restricted by the rotating unit 8. This allows technicians to swing the other end of the upper feed trough 3 or the lower feed trough 4 around the rotating unit 8, enabling more precise control over the angle adjustment range. Since the rotating unit 8 continuously provides partial support to the upper feed trough 3 or the lower feed trough 4 during the angle adjustment process, it makes it easier and less strenuous for technicians to install the upper feed trough 3 or the lower feed trough 4 together with the base housing 1.

[0040] Furthermore, such as Figure 3 As shown, the rotating unit 8 includes a mounting block 81 installed on the outer side of the upper feed trough 3 or the lower feed trough 4. A rotating shaft 82 is provided through the mounting block 81 and the two are rotatably connected. One end of the rotating shaft 82 is fixedly connected to the side wall of the base shell 1 on the side adjacent to it.

[0041] In the above embodiments, the mounting block 81 is positioned on the outer side of the upper end of the upper feed trough 3 or the lower feed trough 4. This reduces their impact on the material during material transport and also prevents material from contaminating the rotating shaft 82 on the mounting block 81, thus affecting the smoothness of their rotation. In this application, one end of the rotating shaft 82 is fixedly connected to the base housing 1, and the other end of the rotating shaft 82 is rotatably connected to the mounting block 81. In this way, the rotating shaft 82 can share part of the weight of the upper feed trough 3 or the lower feed trough 4 through the base housing 1, while also ensuring that the upper feed trough 3 or the lower feed trough 4 can rotate smoothly around its own axis when the angle of the upper feed trough 3 or the lower feed trough 4 is adjusted.

[0042] Furthermore, such as Figure 1 and Figure 2 As shown, the first adjustment hole 51, the second adjustment hole 52, the third adjustment hole 53, the fourth adjustment hole 61 and the fifth adjustment hole 62 are all arc-shaped through holes. The centers of the first adjustment hole 51, the second adjustment hole 52 and the third adjustment hole 53 are located on the axis of the upper rotating shaft 82 of the upper feed trough 3, and the centers of the fourth adjustment hole 61 and the fifth adjustment hole 62 are located on the axis of the upper rotating shaft 82 of the lower feed trough 4.

[0043] The distances between the first adjusting hole 51, the second adjusting hole 52, and the third adjusting hole 53 on the upper feeding groove 3 and the upper rotating shaft 82 of the upper feeding groove 3 increase sequentially. The length of the first adjusting hole 51 is less than the length of the second adjusting hole 52, and the length of the second adjusting hole 52 is less than the length of the third adjusting hole 53.

[0044] The distance between the fourth adjustment hole 61 and the fifth adjustment hole 62 on the lower feed trough 4 and the upper feed trough 3 rotating shaft 82 increases sequentially, and the length of the fourth adjustment hole 61 is less than the length of the fifth adjustment hole 62.

[0045] In the above embodiments, since both the upper feed trough 3 and the lower feed trough 4 rotate around their respective upper shafts 82 when adjusting their angles, the movement trajectory of a specific point on the upper feed trough 3 or the lower feed trough 4 is always an arc centered on the axis of the corresponding shaft 82, and the greater the distance from the shaft 82, the greater the range of rotation. Based on this, the shape and size of the first adjustment hole, the second adjustment hole 52, the third adjustment hole 53, the fourth adjustment hole 61, and the fifth adjustment hole 62 are set in the manner described above. The lengths of the first adjustment hole, the second adjustment hole 52, the third adjustment hole 53, the fourth adjustment hole 61, and the fifth adjustment hole 62 are all greater than the adjustable range of the angle of the upper feed trough 3 or the lower feed trough 4 at their corresponding positions. In this way, when it is necessary to adjust the tilt angle of the fixed upper feed trough 3 or the lower feed trough 4, the technician does not need to completely unscrew the first nut 55 on the first bolt 54 or the second nut 64 on the second bolt 63. As long as there is a gap between the first nut 55 and the second nut 64 and the base shell 1, the tilt angle of the upper feed trough 3 or the lower feed trough 4 can be adjusted. This can prevent the risk of loss of the first bolt 54, the first nut 55, the second bolt 63, or the second nut 64 after disassembly.

[0046] Furthermore, such as Figure 1 and Figure 2 As shown, two first bolts 54 and a first nut 55 are installed in the third adjusting hole 53, and two second bolts 63 and a second nut 64 are installed in the fifth adjusting hole 62.

[0047] In the above embodiments, the third adjustment hole 53 is the fixed position on the upper feed trough 3 that is furthest from its upper end rotating shaft 82, and the fifth adjustment hole 62 is the fixed position on the lower feed trough 4 that is furthest from its upper end rotating shaft 82. A first bolt 54, a first nut 55, a second bolt 63, and a second nut 64 are added to the third adjustment hole 53 and the second adjustment hole 52, respectively, which can further improve the stability of the upper feed trough 3 and the lower feed trough 4 after they are fixed.

[0048] The implementation principle of this embodiment is as follows: When in use, the vibrating feeder of this application can feed two different materials onto the upper feed trough 3 and the lower feed trough 4 respectively. Since both the upper feed trough 3 and the lower feed trough 4 are installed on the base housing 1 equipped with a vibrator, when the base housing 1 vibrates during use, the upper feed trough 3 and the lower feed trough 4 can vibrate synchronously with the base housing 1, and use this vibration to transport the two different materials to different locations or devices. Compared with the prior art, the vibrating feeder of this application can achieve the transmission effect of two different materials with a single device. Since the upper feed trough 3 and the lower feed trough 4 are arranged sequentially in the vertical direction and are installed on the same base housing 1 sharing the same set of vibrators, not only does it not occupy too much production area during use, but the production cost can also be effectively reduced. When the tilt angle of the upper feed trough 3 needs to be adjusted, the technician loosens the first bolt 54 and the first nut 55 in sequence, and rotates the upper feed trough 3 around the rotating shaft 82 at the top. Similarly, when the tilt angle of the lower feed trough 4 needs to be adjusted, the technician loosens the second bolt 63 and the second nut 64 in sequence, and rotates the lower feed trough 4 around the rotating shaft 82 at the top. This can improve the applicability and flexibility of the vibrating feeder of this application.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
