DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments will be described clearly and completely below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0032] In the description of the present disclosure, it should be understood that the terms "center", "lateral", "longitudinal", "front", "back", "left", "right", "up", "down", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present disclosure and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the scope of protection of the present disclosure.

[0033] In the related art, the trough of the vibrating conveyor makes the material in the trough continuously throw along the conveying direction through its own vibration, so as to realize the forward movement of the material. However, in the process of the trough vibrating to convey the material, due to the influence of various factors such as the installation environment of the equipment, the vibration frequency of the trough, and the impact of the material, the trough is prone to swing and the vibration conveyor body is prone to shake.

[0034] refer to Figure 1 As shown, in some embodiments of the vibrating conveyor provided by the present disclosure, the vibrating conveyor includes a frame 2, a trough 1, a driving device and a buffer device 8. The trough 1 is movably mounted on the frame 2, and the trough 1 is provided with a conveying surface for conveying materials; the driving device is mounted on the frame 2, and the driving device is configured to drive the trough 1 to vibrate relative to the frame 2, thereby causing the materials to move in a first direction ( Figure 1 The buffer device 8 is connected between the frame 2 and the trough body 1, and the buffer device 8 is configured to reduce the relative swing of the trough body 1 and the frame 2 in a second direction, wherein the second direction is perpendicular to the first direction and parallel to the conveying surface.

[0035] When the material is conveyed along the first direction, if the tank body 1 and the frame 2 swing relative to each other, a thrust deviating from the first direction will be generated on the material, causing the material to deviate from the moving direction, thereby affecting the conveying efficiency of the material.

[0036] The present invention reduces the relative swing of the trough body 1 and the frame 2 in the second direction by setting a buffer device 8. On the one hand, the displacement of the trough body 1 in the second direction is reduced, so that the vibration of the conveying surface of the trough body 1 is more regular, and the force of the conveying surface on the material will be more concentrated in the first direction, so that the movement state of the material in the conveying process is more stable, reducing the deviation, accumulation or scattering of the material, ensuring that the material is continuously and evenly conveyed forward according to the predetermined path and speed, which is conducive to improving the conveying efficiency and conveying accuracy, thereby improving the overall conveying efficiency and the automation level of the production line; on the other hand, the buffer device 8 is connected between the frame 2 and the trough body 1, which can effectively reduce the hard collision between the trough body 1 and the frame 2, especially under the working conditions of starting, stopping or sudden load change, etc., it can protect the connection between the two from damage by excessive impact load, and prevent problems such as loosening of fasteners, cracking of welds, fatigue fracture of support parts caused by excessive vibration, thereby improving the reliability of the overall structure of the vibrating conveyor and maintaining the normal operation of the equipment.

[0037] The material selection and structural design of the buffer device 8 can be set according to actual needs, so that it has good buffering performance in the second direction, thereby effectively absorbing the impact force between the frame 2 and the tank body 1.

[0038] refer to Figure 2 As shown, in some embodiments, the buffer device 8 includes a bracket 81 and a buffer structure 82, and the bracket 81 is connected to the tank body 1 and the frame 2 respectively.

[0039] The bracket 81 is connected to the tank body 1 and the frame 2 respectively, and plays the role of stable support and transmission of buffer force.

[0040] In some embodiments, the tank body 1 is provided with a first connecting portion 11 , the frame 2 is provided with a second connecting portion 21 , and both ends of the bracket 81 are respectively connected to the first connecting portion 11 and the second connecting portion 21 .

[0041] The first connection part 11 can be configured to be detachably connected to the main structure of the trough body 1, and the second connection part 21 can also be configured to be detachably connected to the main structure of the frame 2, thereby reducing the impact of the installation of the buffer device 8 on the original structure of the vibration conveyor and facilitating subsequent maintenance.

[0042] The buffer structure 82 can be set at a location that fully considers the actual stress conditions of each part of the vibrating conveyor during operation. For example, the buffer structure 82 can be set at the connection between the bracket 81 and the trough body 1 to at least offset a portion of the load on the trough body 1 in the second direction, thereby reducing the relative swing between the trough body 1 and the frame 2 in the second direction; or, the buffer structure 82 can also be set at the connection between the bracket 81 and the frame 2 to at least offset a portion of the load on the frame 2 in the second direction, thereby reducing the relative swing between the trough body 1 and the frame 2 in the second direction. This flexible configuration method can be adaptively designed according to different working conditions and material characteristics, thereby improving the overall adaptability and buffering efficiency of the equipment.

[0043] Alternatively, a buffer structure 82 may be provided at the connection between the bracket 81 and the tank body 1 and at the connection between the bracket 81 and the frame 2, so as to obtain better buffering performance. This arrangement is equivalent to providing multiple "damping points" on the vibration transmission path, which can more effectively suppress the propagation of vibration energy and further reduce the relative swing between the tank body 1 and the frame 2.

[0044] There are many options for connecting the bracket 81 and the trough body 1, and connecting the bracket 81 and the frame 2, such as shaft hole connection, keyway connection, hinge connection, etc., as long as they do not affect the normal movement of the trough body 1 relative to the frame 2.

[0045] For example, in some embodiments, the buffer device 8 also includes a connecting shaft 83, one end of the bracket 81 connected to the slot body 1 is provided with a connecting hole 811, one end of the connecting shaft 83 is connected to the slot body 1, and the other end is passed through the connecting hole 811, and the buffer structure 82 is installed on the connecting shaft 83.

[0046] In some embodiments, a connecting hole is also provided on the first connecting portion 11 of the trough body 1 , and the connecting shaft 83 is connected to the trough body 1 through the connecting hole provided on the first connecting portion 11 .

[0047] In the above embodiment, there are many options for the structural form of the buffer structure 82, such as elastic sleeves, springs, telescopic structures, etc., which can play a buffering role. These structures can be directly installed on the connecting shaft 83, which is convenient for disassembly and maintenance.

[0048] In some embodiments of the present disclosure, the buffer structure 82 includes a spring and / or a thrust bearing. The spring and the thrust bearing may be used alone or in a coordinated design.

[0049] Specifically, in some embodiments, the spring can be sleeved on the connecting shaft 83, for example, arranged between the trough body 1 and the bracket 81. If the trough body 1 and the frame 2 tend to swing relative to each other due to an unstable load, the force on both ends of the spring will change, causing compression or elongation, which can play a buffering role, thereby reducing the displacement of the trough body 1 that may be caused by the load in the second direction.

[0050] By arranging a thrust bearing in the buffer structure 82, the thrust bearing's ability to withstand axial loads can be utilized to disperse the impact force caused by the unstable load in the second direction through the rolling elements and contact surfaces of the bearing and convert it into a smaller local stress. In addition, the friction and rolling resistance inside the bearing can also consume a portion of the impact energy and help to redistribute the unstable load along the circumference of the bearing, thereby reducing the impact on the trough body 1 and reducing its displacement in the second direction.

[0051] refer to Figure 2 As shown, in some embodiments, the buffer structure 82 includes two one-way thrust bearings respectively arranged on a side of the bracket 81 close to the slot body 1 and a side away from the slot body 1, and the force directions of the two one-way thrust bearings are opposite.

[0052] In the absence of external axial load, the two one-way thrust bearings do not interfere with each other. When the tank body 1 and the frame 2 are affected by the uneven axial load and have a tendency to swing relative to each other, the tank body 1 further transfers the load to the two one-way thrust bearings, and the bracket 81 also generates pressure on the two one-way thrust bearings. In this case, the two one-way thrust bearings can respectively withstand the axial impact force from two directions, play a role in offsetting part of the impact force and redistributing the remaining unbalanced impact force, that is, achieving buffering.

[0053] Furthermore, the bearing structure enables smooth relative rotation between the connecting shaft 83 and the bracket 81 , thereby avoiding interference with the preset vibration of the tank body 1 caused by the buffer device 8 .

[0054] refer to Figure 3 As shown, in some embodiments, grooves 812 ( Figure 3 Only one side is shown, the other side is the same), thereby increasing the stability of the bearing installation and improving the working reliability of the buffer structure 82.

[0055] In some other embodiments, the buffer structure 82 includes a bidirectional thrust bearing disposed in the connecting hole 811 .

[0056] The double-direction thrust bearing can bear loads in two axial directions. The principle of achieving buffering is similar to that of the two unidirectional thrust bearings working together to achieve buffering. In practical applications, the selection of bearings can be adjusted according to different situations such as buffering requirements, equipment structure, and maintenance methods.

[0057] refer to Figure 2 As shown, in some embodiments, the buffer device further includes a limiter 84 , and the limiter 84 is configured to limit the axial displacement of the bracket 81 and / or the buffer structure 82 on the connecting shaft 83 .

[0058] There are many options for the structural form and setting position of the limiting member 84. For example, the limiting member 84 can be a buckle, a snap ring, a shaft end cover, etc., which are arranged on the connecting shaft 83.

[0059] refer to Figure 2 and Figure 4 When the buffer structure 82 includes a thrust bearing, the limit member 84 can be set as a bearing cover corresponding to the specification and model of the thrust bearing, which can effectively ensure the working reliability of the bearing and facilitate disassembly and assembly.

[0060] In the above embodiment, if a buffer structure 82 is to be provided at the connection between the frame 2 and the bracket 81 , the buffer structure 82 at this position may be provided similarly to the buffer structure 82 at the connection between the tank body 1 and the bracket 81 .

[0061] In some embodiments, the vibrating conveyor includes at least two buffer devices 8 , and the at least two buffer devices 8 are symmetrically arranged on both sides of the frame 2 ; and / or, the at least two buffer devices 8 are symmetrically arranged on both sides of the trough body 1 .

[0062] The arrangement position of the buffer device 8 can be set according to the size of the vibration conveyor, the length of the trough body 1, etc.

[0063] Specifically, a plurality of pairs of buffer devices 8 may be provided, each pair of buffer devices 8 being symmetrically arranged on both sides of the frame 2 and the tank body 1, and both ends of the bracket 81 of each buffer device 8 being respectively connected to the frame 2 and the tank body 1, thereby achieving multi-point stabilization of the frame 2 and the tank body 1, and effectively preventing the frame 2 and the tank body 1 from deviating significantly in the second direction.

[0064] refer to Figure 1As shown, in some embodiments, the driving device includes a motor, a balancing body 3, a transmission assembly 5, a connecting rod assembly 4 and a rocker assembly 6, the transmission assembly 5 is connected between the motor and the connecting rod assembly 4, the balancing body 3 is connected between the connecting rod assembly 4 and the rocker assembly 6, the rocker assembly 6 is connected to the slot body 1, and the motor is configured to drive the transmission assembly 5 to drive the connecting rod assembly 4 to move, so that the connecting rod assembly 4 pushes the balancing body 3 to move, and then the balancing body 3 drives the rocker assembly 6 to drive the slot body 1 to perform an approximate simple harmonic vibration synchronously and opposite to the balancing body 3.

[0065] The transmission assembly 5 includes a pulley and an eccentric mechanism. The motor drives the pulley to rotate, and the output shaft of the pulley drives the eccentric mechanism to rotate, thereby driving the connecting rod assembly 4 to move, so that the connecting rod assembly 4 pushes the balancing body 3 to move.

[0066] refer to Figure 1 and Figure 2 As shown, the two ends of the rocker assembly 6 are respectively connected to the balancing body 3 and the slot body 1, and the middle part of the rocker assembly 6 is connected to the frame 2. These connections are all movable connections, so that the balancing body 3 can drive the rocker assembly 6 to drive the slot body 1 to perform an approximate simple harmonic vibration synchronously and oppositely to the balancing body 3.

[0067] When the driving device drives the trough body 1, when the vibration acceleration of the trough body 1 reaches a preset value, the material will be continuously thrown in the trough body 1 along the conveying direction (i.e., the first direction mentioned above), so that the material moves forward to achieve the purpose of conveying and loosening the material.

[0068] In the above embodiments, reference Figure 2 As shown, the buffer device 8 can be arranged corresponding to the rocker assembly 6, which is equivalent to playing the role of auxiliary support to increase the stability of the connection structure between the tank body 1 and the frame 2.

[0069] Among them, simple harmonic vibration refers to a periodic vibration of an object near its equilibrium position in the form of a sine or cosine function. Its characteristic is that the restoring force it receives during the vibration process is proportional to the displacement, and its direction always points to the equilibrium position.

[0070] In a specific embodiment of the vibrating conveyor disclosed in the present invention, the periodic driving force generated by the driving device causes the trough body 1 to reciprocate in a preset direction. Ideally, when the vibrating conveyor is in a stable working state, the vibration of the trough body 1 can be approximately regarded as a simple harmonic vibration, so that the material is continuously thrown in the trough body 1 along the preset conveying direction.

[0071] Although in practical applications, the actual vibration of the tank body 1 may slightly deviate from the ideal simple harmonic vibration due to factors such as mechanical nonlinearity and uneven material filling, this deviation usually does not significantly affect the normal operation of the equipment. Therefore, in engineering calculations and analysis, an approximate simple harmonic vibration model can still be used to describe and predict the movement law of the tank body. Such a simplified treatment is beneficial not only to theoretical analysis, but also to design and adjust equipment parameters.

[0072] Refer to the following Figure 1 to Figure 4 , a specific embodiment of the vibrating conveyor disclosed in the present invention is described:

[0073] In this embodiment, the vibrating conveyor includes legs 7 , a frame 2 , a trough body 1 , a driving device and a buffer device 8 .

[0074] The frame 2 is mounted on a plurality of legs 7 so that the vibrating conveyor as a whole is stably supported on the ground.

[0075] The driving device includes a motor, a balancing body 3, a transmission assembly 5, a connecting rod assembly 4 and a rocker assembly 6. The transmission assembly 5 is connected between the motor and the connecting rod assembly 4, the balancing body 3 is connected between the connecting rod assembly 4 and the rocker assembly 6, and the rocker assembly 6 is connected to the trough body 1. The motor is configured to drive the transmission assembly 5 to drive the connecting rod assembly 4 to move, so that the connecting rod assembly 4 pushes the balancing body 3 to move, and then the balancing body 3 drives the rocker assembly 6 to drive the trough body 1 to perform an approximately simple harmonic vibration in a synchronous and opposite direction with the balancing body 3, so that the material is moved in the trough body 1 along the conveying direction ( Figure 1 Make continuous throwing motion (in the direction indicated by the arrow in the middle).

[0076] In this embodiment, the vibrating conveyor includes a plurality of buffer devices 8 corresponding to the rocker assemblies 6. A plurality of pairs of rocker assemblies 6 are symmetrically arranged on both sides of the frame 2 to connect the tank body 1, the frame 2 and the balancing body 3. A plurality of pairs of buffer devices 8 are also symmetrically arranged on both sides of the frame 2, and the buffer device 8 includes a bracket 81, a buffer structure 82, a connecting shaft 83 and a stopper 84. The bracket 81 is provided with connecting holes 811 at both ends, and two connecting shafts 83 are respectively inserted into the connecting holes 811 at both ends to connect the bracket 81 to the tank body 1 and the frame 2, respectively, and the buffer structure 82 is sleeved on the connecting shaft 83.

[0077] Specifically, the buffer structure 82 includes two one-way thrust bearings, which are respectively arranged on the inner side (the side close to the tank body 1 and the frame 2) and the outer side (the side away from the tank body 1 and the frame 2) of the bracket 81, and the force directions of the two one-way thrust bearings are opposite.

[0078] The stopper 84 is a bearing cap adapted to the one-way thrust bearing, which is sleeved on the connecting shaft 83 and connected with the threaded end of the connecting shaft 83 to compress the two one-way thrust bearings. The bearing cap and the bracket 81 are both provided with grooves for mounting bearings.

[0079] Through the description of multiple embodiments of the vibrating conveyor disclosed in the present invention, it can be seen that the vibrating conveyor disclosed in the present invention is equipped with a buffer device, which can reduce the relative swing of the trough body and the frame in the second direction, ensure that the trough body maintains a relatively stable vibration in the preset direction, and can effectively reduce the deviation of the material conveying direction caused by the sway of the trough body, thereby improving the conveying accuracy and efficiency of the material. In addition, the buffer device can absorb at least a part of the impact force between the frame and the trough body, effectively reducing the hard collision between the two, especially when the equipment is started, stopped, and the load suddenly changes, it can protect the connection parts from being damaged by excessive impact loads, thereby improving the reliability and service life of the overall structure of the vibrating conveyor.

[0080] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present disclosure rather than to limit it. Although the present disclosure has been described in detail with reference to the preferred embodiments, ordinary technicians in the relevant field should understand that without departing from the principles of the present disclosure, the specific implementation methods of the present disclosure can still be modified or some technical features can be replaced by equivalents, and these modifications and equivalent replacements should be included in the scope of the technical solution for protection of the present disclosure.
