[0002] Belt conveyor is the abbreviation of belt conveyor. It has fixed and mobile types, simple structure and high efficiency. It is a continuous conveying machine that uses a flexible conveyor belt as a material carrying and traction component. An endless conveyor belt surrounds the driving roller and the redirecting roller, and the upper and lower branches between the two rollers are supported by several rollers. The material is placed on the upper branch, and the friction between the driving roller and the belt is used to drag the conveyor belt and the material to run.

Due to the transportation length and site conditions of belt conveyors, overlapping or reloading is often used to solve transportation problems when the distance is long or when turning. Since the materials thrown down when the belt conveyor is overlapped or reloaded will produce a large impact force on the lower belt and rollers, the lower belt and rollers are required to withstand continuous or pulsating impacts, resulting in a shortened service life, a high maintenance rate, and increased costs.

DETAILED DESCRIPTION

[0028] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is described in detail below in conjunction with the accompanying drawings. The description in this part is only exemplary and explanatory and should not have any limiting effect on the protection scope of the present invention.

[0029] Embodiment 1:

[0030] like Figure 1—4 shows: an energy storage and release structure of a buffer roller, comprising a roller 1, wherein both ends of the roller 1 are rotatably mounted on a bearing seat 2, wherein the bearing seat 2 is mounted on a buffer assembly 3, wherein the buffer assembly 3 comprises an upper connecting seat 31, wherein both ends of the upper connecting seat 31 are rotatably connected to the upper end of an upper connecting arm 32 via a pin shaft, wherein the bottom end of the upper connecting arm 32 is rotatably connected to two oppositely arranged side connecting seats 33 via a pin shaft, wherein the bottom end of the side connecting seat 33 is rotatably connected to the top end of a lower connecting arm 34 via a pin shaft, wherein the bottom end of the lower connecting arm 34 is rotatably connected to a lower connecting seat 35 via a pin shaft, wherein an energy absorbing buffer assembly 36 is mounted on the side connecting seat 33, wherein the energy absorbing buffer assembly 36 comprises an inner slide rod 364 and an outer cylinder body 361, The inner slide rod 364 is slidably inserted in the outer cylinder body 361, and one end of the inner slide rod 364 and the outer cylinder body 361 is installed on two opposite side connecting seats 33. The other end of the inner slide rod 364 is connected to a piston 363, and an oil overflow hole 366 is provided on the piston 363. The interior of the outer cylinder body 361 is filled with damping oil 362. An energy storage spring 365 is installed on the inner slide rod 364 inside the outer cylinder body 361. After the roller 1 is impacted and moved downward, the upper connecting seat 31 moves downward stably under the support of the connecting rod mechanism below. At this time, the energy storage spring 365 absorbs energy and the piston 363 is resisted by the damping oil 362 when moving, so that the roller 1 is buffered and descends. The energy storage spring 365 can cooperate with the damping oil 362 later. 2, the damping effect slowly releases the kinetic energy to make the roller 1 move up and reset. The length of the upper connecting arm 32 is the same as the length of the lower connecting arm 34. The upper connecting seat 31 is arranged parallel to the lower connecting seat 35. The connecting rod mechanism composed of the upper connecting seat 31, the upper connecting arm 32, the lower connecting arm 34 and the lower connecting seat 35 can cooperate with the use of the energy absorption buffer assembly 36 to stably drive the roller 1 to move up and down. The upper connecting seat 31, the side connecting seat 33 and the lower connecting seat 35 are all angle iron structures. The upper connecting seat 31, the side connecting seat 33 and the lower connecting seat 35 have a stable structure and a light weight. The pin shaft used to connect the upper connecting arm 32 and the lower connecting seat 35 can be stably installed to ensure the supporting strength of the overall structure of the buffer assembly 3. The outer side of the piston 363 is provided with A dynamic sealing structure is provided. A dynamic sealing structure is provided at the connection between the damping oil 362 and the inner slide rod 364. The use of the dynamic sealing structure can ensure the sealing of the cavity of the outer cylinder body 361, thereby ensuring the stable flow of the damping oil 362 through the oil overflow hole 366. The energy storage spring 365 is slidably mounted on the inner slide rod 364. The two ends of the energy storage spring 365 are tightly pressed against the inner end surface of the outer cylinder body 361 and one end surface of the piston 363. The energy storage spring 365 can effectively absorb and release the potential energy when the upper connecting seat 31 is lowered. The axis of the oil overflow hole 366 is parallel to the axis of the piston 363. The number of the oil overflow holes 366 is multiple, and the damping oil 362 can flow stably through the oil overflow holes 366 opened on the piston 363.

[0031] The working principle of the present technical solution is as follows: when the belt conveyed on the roller 1 is subjected to the downward impact force of the conveyed object, the force of the roller 1 is transmitted to the bearing seat 2, and the bearing seat 2 drives the upper connecting seat 31 to move downward, and the upper connecting seat 31 that moves downward drives the upper end of the upper connecting arm 32 to move through the pin shaft, and the lower end of the upper connecting arm 32 rotates outward when it moves downward, and drives the side connecting seat 33 to move outward under the action of the pin shaft, and the side connecting seat 33 moves stably under the support and positioning of the lower connecting arm 34 and the lower connecting seat 35 below, thereby driving the inner slide rod 364 and the piston 363 to the outside of the outer cylinder body 361 Move, at this time, the energy storage spring 365 is squeezed by the piston 363 to generate elastic energy storage. At the same time, when the piston 363 moves, the damping oil 362 in the outer cylinder body 361 on one side of the piston 363 moves to the other side of the piston 363 through the oil overflow hole 366. The flow resistance of the damping oil 362 forms a damping buffer, so that the roller 1 slowly lowers its height. When the impact force potential energy of the heavy object disappears, the energy storage spring 365 releases its elastic energy and pushes the piston 363 to reset and move. Similarly, the damping oil 362 plays a damping role, so that the energy storage spring 365 slowly releases kinetic energy.
