Description

Technical Field

[0001] The utility model belongs to the technical field of tubular vibrating feeders, in particular to a tubular vibrating feeder with an optimized vibration function. Background Art

[0002] In salt production, tubular vibrating feeders are often used to feed and transport salt because of its particle size characteristics. Tubular vibrating feeders use a vibrating motor to force the load-bearing tube to perform simple harmonic vibration or approximate simple harmonic vibration in a certain direction. When the acceleration of its vibration reaches a certain value, the material is continuously thrown or slid along the direction of motion in the conveying tube, thereby moving the material forward and achieving the purpose of material transportation.

[0003] The patent document with publication number CN204508020U discloses a vacuum tube vibrating feeder, comprising a feeding tube body and an exciting device, the exciting device comprising two eccentric vibrating motors and a thrust plate, the eccentric vibrating motor is fixed on the thrust plate, the thrust plate is fixed on the outer wall of the feeding tube body, the two ends of the feeding tube body are a feed port and a discharge port, respectively, which are connected to the outlet of the silo and the inlet of the unloading chute, the limiting mechanism is arranged on both sides of the feed port and is fixed on the connecting support frame, a vibration damping spring is arranged between the connecting support frame and the feeding tube body, the vibration damping spring supports the vibration damping frame, and the vibration damping frame is fixed on the feeding tube body, the feeding tube body performs periodic reciprocating vibration under the action of the eccentric vibrating motor, during the vacuum treatment of the molten steel, the space for the vibration damping frame to move upward is limited by the limiting mechanism, so that the feeder maintains a balanced state and normal feeding capacity, can shorten the horizontal distance between the discharge port of the vacuum hopper and the feed port of the vacuum slot system, and has the characteristics of low failure rate and convenient maintenance and disassembly.

[0004] The vibrating feeder tube and the support frame in the above-mentioned comparative document are supported only by the vibration damping spring, so that all the vibrations generated by the vibration motor can be transmitted to the vibrating feeder tube. Based on the above principle, the basic principle of moving the material during the simple harmonic vibration of the vibration motor is as follows: the feeder tube receives the vibration and lifts the material inside it upwards. At this time, the feeder tube vibrates and moves a slight distance toward the discharge hopper side. At this time, the material lifted upward will fall to a position closer to the discharge hopper when it falls, and then the feeder tube is reset under the action of the reset spring. Compared with before, the material has moved toward the discharge hopper. A small distance is formed to form a small displacement. Under the support of the vibration frequency, within a fixed time, based on the above principle, the material will move hundreds or thousands of small displacements, and then form a visible movement in the feeding pipe; so it can be said that the material in the feeding pipe can be promoted to move from the feed hopper to the discharge hopper. It depends entirely on the up and down vibration of the feeding pipe and the front and back vibration along the axis of the feeding pipe. The left and right vibration has no practical help for the conveying operation of the feeding pipe, and may even interfere with the vibration feeding speed. Therefore, the utility model proposes the need to optimize the vibration mode of the feeding pipe. Summary of the Invention

[0005] The purpose of the present utility model is to provide a tubular vibrating feeder with an optimized vibration function to solve the technical problem that the vibration transmission from the vibration motor to the feeding pipe in the above-mentioned background art is not optimized.

[0006] The above technical purpose of the present utility model is achieved through the following technical solutions:

[0007] A tubular vibrating feeder with an optimized vibration function includes: a support frame, a trough cylinder, and a feeding pipe; the number of the trough cylinders is two, which are cylindrical structures with a trough-shaped cross-section. The trough cylinders are fixed at a height by the support frame. A horizontally tubular feeding pipe is inserted through the inner rings of the two trough cylinders. The two sides of the feeding pipe are tangent to the inner rings of the trough cylinders. End rings with an annular structure are respectively embedded at both ends of the feeding pipe. A return spring is connected between the end ring and the adjacent trough cylinder. The return spring is not in contact with the outer embedding on the feeding pipe. An upper-opening feeding hopper is conducted at one end of the feeding pipe, and a lower-opening discharging hopper is conducted and connected at the other end of the feeding pipe away from the feeding hopper. A number of vibration motors are fixed in the middle of the feeding pipe.

[0008] Further: In order to facilitate the connection between the return spring and the trough cylinder, a spring seat ring with an annular plate structure is concentrically fixed at the end of the two return springs close to the trough cylinder. The spring seat ring is externally embedded and fixed on the outer ring of the trough cylinder or fixed at the end of the trough cylinder.

[0009] Further: When the spring seat ring is fixed at the end of the trough cylinder, the longitudinal cross-sectional inner ring contour of the spring seat ring is greater than or equal to the longitudinal cross-sectional inner ring contour of the trough cylinder.

[0010] Further: In order to further reduce the left and right vibration of the feeding pipe and limit the rotational movement between the trough cylinder and the feeding pipe, the trough cylinder and the feeding pipe are movably connected by an anti-deviation and stability mechanism. The anti-deviation and stability mechanism includes: a fixed hinge seat, a movable hinge seat, a first strip, a second strip, and a hinge shaft; wherein the fixed hinge seat is fixed on the outer wall of the trough cylinder, the movable hinge seat is fixed on the outer wall of the feeding pipe. A first strip with a strip structure is rotatably fitted on the fixed hinge seat, and a second strip with a strip structure is rotatably fitted on the movable hinge seat. The other ends of the first strip and the second strip are both rotatably fitted on a hinge shaft with a horizontal axis by bearings. The contact surfaces of the first strip and the second strip are vertical planes, and the first strip and the second strip are mutually attached by their vertical surfaces.

[0011] Further: In order to limit the left and right vibration of the feeding pipe without affecting the up and down vibration of the feeding pipe, as shown in the figure, when there is no external force acting on the feeding pipe, the feeding pipe is suspended in the trough cylinder by the flexible support of the return spring, so that an up and down vibration cavity for the feeding pipe to move up and down is formed in the trough cylinder, and the up and down vibration cavity and the feeding pipe form a horizontal sliding fit.

[0012] Further: To facilitate the connection between the motor bracket and the feed pipe, a plurality of motor brackets are fixed on the feed pipe, and the vibrating motor is fixed on the motor bracket by bolts.

[0013] Further: When the number of motor brackets is one group, the motor bracket is arranged in the middle of the pipe section of the feed pipe. When the number of motor brackets is more than one group, the motor brackets are evenly distributed on the pipe section of the feed pipe.

[0014] Further: To prevent the operator from accidentally touching the vibrating motor and causing vibration injury and scalding (the vibrating motor will get hot after working for a long time), both the motor bracket and the anti-deviation and stability mechanism are arranged below the feed pipe, and a protective fence is provided on the support frame to shield and protect the motor bracket, vibrating motor, and anti-deviation and stability mechanism as a whole.

[0015] Further: To prevent the overall displacement of the support frame and the trough cylinder caused by vibration, a fixing plate is provided at the bottom of the support frame, and a countersunk hole for fixing bolts is provided on the fixing plate.

[0016] In summary, the utility model has the following beneficial effects:

[0017] ① The vibration direction is optimized: By setting up the trough cylinder and the feed pipe, it can promote the movement of salt material in the feed pipe from the feed hopper to the discharge hopper. It completely depends on the up-and-down vibration and the front-and-back vibration along the axis of the feed pipe. The left-and-right vibration has no actual help to the conveying operation of the feed pipe and even interferes with the vibrating feeding speed. Therefore, it is necessary to optimize the left-and-right vibration of the feed pipe. So, the left and right sides of the feed pipe will be limited by the inner wall of the trough cylinder, filtering out the left-and-right vibration generated by the vibrating motor, making the feed pipe only vibrate up and down and back and forth, avoiding the left-and-right vibration from interfering with the vibrating feeding, and improving the working efficiency of the vibrating feeding.

[0018] ② Stable and anti-displacement: By setting up the anti-deviation and stability mechanism, when the anti-deviation and stability mechanism works, the first plate can only rotate around the fixed hinge seat, and the second plate can only rotate around the movable hinge seat. And the contact surfaces of the first plate and the second plate are vertical and fit, which causes the movable hinge seat to only move up and down or back and forth relative to the fixed hinge seat and cannot move left and right. Also, because the movable hinge seat is fixed on the feed pipe and the fixed hinge seat is fixed on the trough cylinder, it further filters out the left-and-right vibration generated by the vibrating motor, making the feed pipe only vibrate up and down and back and forth, avoiding the left-and-right vibration from interfering with the vibrating feeding, and improving the working efficiency of the vibrating feeding. At the same time, due to the rotational limit of the anti-deviation and stability mechanism between the trough cylinder and the feed pipe connected by the anti-deviation and stability mechanism, there is no relative rotation between the trough cylinder and the feed pipe, avoiding the relative rotation of the trough cylinder and the feed pipe due to vibration, affecting the elastic force of the return spring and the orientation of the feed hopper and the discharge hopper, and further improving the working stability of the equipment.

Specific embodiments

[0027] The present utility model will be further described in detail below with reference to the accompanying drawings.

[0028] Embodiment:

[0029] Please refer to Figures 1 - 7 , the present utility model provides the technical solution:

[0030] A tubular vibrating feeder with an optimized vibration function, comprising: a support frame 1, a trough cylinder 2, and a feed pipe 3; the number of the trough cylinders 2 is two, which are cylindrical structures with a trough-shaped cross-section. The trough cylinders 2 are fixed at a raised height by the support frame 1. A feed pipe 3 with a horizontal tubular structure is inserted through the inner rings of the two trough cylinders 2. The two sides of the feed pipe 3 are tangent to the inner rings of the trough cylinders 2. End rings 31 with an annular structure are respectively embedded at both ends of the feed pipe 3. A return spring 4 is connected between the end ring 31 and the adjacent trough cylinder 2. The return spring 4 is not in contact with the outer embedding on the feed pipe 3. One end of the feed pipe 3 is communicated with a feed hopper 5 with an upward opening, and the other end of the feed pipe 3 far from the feed hopper 5 is communicated and connected with a discharge hopper 6 with a downward opening. A plurality of vibration motors 8 are fixed in the middle of the feed pipe 3.

[0031] One end of the two return springs 4 close to the trough cylinder 2 is concentrically fixed with a spring seat ring 21 with an annular plate structure. The spring seat ring 21 is externally embedded and fixed on the outer ring of the trough cylinder 2 or fixed at the end of the trough cylinder 2.

[0032] When the spring seat ring 21 is fixed at the end of the trough cylinder 2, the longitudinal cross-sectional inner ring contour of the spring seat ring 21 is greater than or equal to the longitudinal cross-sectional inner ring contour of the trough cylinder 2.

[0033] An anti-deviation and stabilization mechanism 9 is used for the movable connection between the trough cylinder 2 and the feed pipe 3. The anti-deviation and stabilization mechanism 9 includes: a fixed hinge seat 91, a movable hinge seat 92, a first strip 93, a second strip 94, and a hinge shaft 95; wherein the fixed hinge seat 91 is fixed on the outer wall of the trough cylinder 2, the movable hinge seat 92 is fixed on the outer wall of the feed pipe 3. A first strip 93 with a strip structure is rotatably fitted on the fixed hinge seat 91, and a second strip 94 with a strip structure is rotatably fitted on the movable hinge seat 92. The other ends of the first strip 93 and the second strip 94 are both rotatably fitted on a hinge shaft 95 with a horizontal axis by bearings. The contact surfaces of the first strip 93 and the second strip 94 are vertical planes, and the first strip 93 and the second strip 94 are mutually attached by their vertical surfaces.

[0034] When there is no external force acting on the feed pipe 3, the feed pipe 3 is suspended in the trough cylinder 2 by the flexible support of the return spring 4, so that an up-and-down vibration cavity 22 for the supply pipe 3 to move up and down is formed in the trough cylinder 2, and the up-and-down vibration cavity 22 and the feed pipe 3 form a horizontal sliding fit.

[0035] A plurality of motor brackets 7 are fixed on the feed pipe 3, and the vibration motors 8 are fixed on the motor brackets 7 by bolts.

[0036] When the number of the motor brackets 7 is one group, the motor bracket 7 is arranged in the middle of the pipe section of the feed pipe 3. When the number of the motor brackets 7 is more than one group, the motor brackets 7 are evenly distributed on the pipe section of the feed pipe 3.

[0037] To prevent the operating workers from accidentally contacting the vibration motor 8 and causing vibration injuries and burns (the vibration motor 8 will get hot after working for a long time), both the motor bracket 7 and the anti-deviation and stabilization mechanism 9 are arranged below the feed pipe 3, and a guardrail 11 is provided on the support frame 1 to shield and protect the motor bracket 7, the vibration motor 8, and the anti-deviation and stabilization mechanism 9 as a whole.

[0038] A fixing plate 13 is provided at the bottom of the support frame 1, and a counterbore 12 for fixing bolts is provided on the fixing plate 13.

[0039] Brief description of the usage process:

[0040] During use, as Figure 4 described, first use bolts to penetrate the counterbore 12 to fix the fixing plate 13 and the support frame 1 to the ground, and the trough cylinder 2 is fixed along with the support frame 1; then put the salt material into the feed hopper 5, the salt material enters the feed pipe 3 from the feed hopper 5, power on all the vibration motors 8 to make them work, the vibration motor 8 transmits the vibration to the feed pipe 3 through the motor bracket 7, the feed pipe 3 receives the vibration and lifts the salt material inside it forward and upward. At this time, the feed pipe 3 vibrates and displaces a slight distance toward the side of the discharge hopper 6. When the salt material lifted forward and upward falls due to inertia, it will land at a position closer to the discharge hopper 6. Then, under the action of the return spring 4, the feed pipe 3 resets. Compared with before, the salt material has displaced a small distance toward the discharge hopper 6 to form a small displacement. With the addition of the vibration frequency, within a fixed time, based on the above principle, the salt material will move hundreds or thousands of small displacements, and then a visible movement will be formed inside the feed pipe 3, thereby transporting the salt material from the feed hopper 5 to the discharge hopper 6 and discharging it from the discharge hopper 6 to the next processing or packaging unit to complete the feeding operation.

[0041] Based on the above principle, it can be known that to promote the movement of the salt material in the feed pipe 3 from the feed hopper 5 toward the discharge hopper 6, it completely depends on the up-and-down vibration of the feed pipe 3 and the front-and-back vibration along the axis of the feed pipe 3 (this orientation takes Figure 5 the perspective as a reference). The left-and-right vibration has no actual help to the conveying operation of the feed pipe 3 and even interferes with the vibration feeding speed. Therefore, it is necessary to optimize the left-and-right vibration of the feed pipe 3; so the left and right sides of the feed pipe 3 are limited by the inner wall of the trough cylinder 2 to filter out the left-and-right vibration generated by the vibration motor 8, so that the feed pipe 3 can only vibrate up and down and back and forth, avoiding the left-and-right vibration from interfering with the vibration feeding and improving the working efficiency of the vibration feeding; when the feed pipe 3 vibrates up and down in the up-and-down vibration cavity 22, it will drive the end ring 31 to vibrate up and down, and then the two groups of return springs 4 connected to the end ring 31 will generate a slight up-and-down deflection, causing the return springs 4 to generate a return elastic force. Under the action of the return elastic force, the up-and-down vibration is controlled within a reasonable vibration range, and it also prevents the feed pipe 3 from being displaced due to the up-and-down vibration.

[0042] When the feeding pipe 3 vibrates back and forth along its axis, the end rings 31 at both ends of the feeding pipe 3 follow the back-and-forth vibration. Also, since the trough cylinder 2 is supported and fixed by the support frame 1, the two groups of return springs 4 connected to the end rings 31 are such that one group is compressed and the other is stretched, generating an elastic force that pulls or pushes the feeding pipe 3 back to its original position, controlling the back-and-forth vibration within a reasonable range and ensuring the stability of the feeding rate of the feeding pipe 3.

[0043] When the anti-deviation and stabilization mechanism 9 works, the first plate 93 can only rotate around the fixed hinge seat 91, and the second plate 94 can only rotate around the movable hinge seat 92. Moreover, the contact surfaces of the first plate 93 and the second plate 94 are vertical and in contact, which results in the movable hinge seat 92 being able to move only up and down or back and forth relative to the fixed hinge seat 91 and not being able to move left and right. Also, since the movable hinge seat 92 is fixed on the feeding pipe 3 and the fixed hinge seat 91 is fixed on the trough cylinder 2, the left-and-right vibration generated by the vibration motor 8 is further filtered out, enabling the feeding pipe 3 to vibrate only up and down and back and forth, avoiding left-and-right vibration interfering with the vibrating feeding and improving the working efficiency of the vibrating feeding. At the same time, due to the rotational limit of the anti-deviation and stabilization mechanism 9 between the trough cylinder 2 and the feeding pipe 3 connected by the anti-deviation and stabilization mechanism 9, relative rotation between the trough cylinder 2 and the feeding pipe 3 cannot occur, preventing the relative rotation of the vibrating trough cylinder 2 and the feeding pipe 3 from affecting the elastic force of the return spring 4 and the orientations of the feed hopper 5 and the discharge hopper 6.

[0044] This specific embodiment is only an explanation of the present invention and is not a limitation thereof. After reading this specification, those skilled in the art can make modifications to this embodiment that do not contribute creatively as needed, but as long as it is within the scope of the claims of the present invention, it is protected by the patent law.
