As described in the background art, in an already built building (for example, in a factory building), when materials produced in an upper floor layer are transported to a lower floor layer, holes are generally formed in the floor layers between the floor layers, and then a chute is installed, so that the materials directly enter a designated position of the lower floor layer (for example, a feed inlet of production equipment placed in the lower floor layer) through the chute, thereby playing a role in transporting the materials. The different materials have different fluidity due to the variable properties of repose angle, compressibility, spatula angle and adhesiveness, and the inclination angle of the chute needs to be changed continuously to convey the materials with different fluidity by using the chute. Because this kind of upstream and downstream automated product is located adjacent floor generally, and the elephant trunk needs to pass the floor and connects upstream and downstream automated product, often leaves the space of giving the elephant trunk in this kind of overall arrangement limited, can't change the inclination of elephant trunk according to the flow characteristic of material, from the transportation efficiency who leads to the material reduces, appears the material and can detain the condition in the elephant trunk even, seriously influences the production efficiency of enterprise.

As shown in fig. 1 and 2, the floor 6 between two adjacent floors is provided with a through hole 61 for connecting the two floors, and for convenience of description, the two adjacent floors may be named as an upper floor and a lower floor, the upstream equipment may be placed on the upper floor, and the downstream equipment may be placed on the lower floor. The floor 6 in fig. 1 and 2 is shown in phantom to show the floor 6 in perspective, which serves to facilitate understanding of the present solution.

The chute 2 comprises a feeding end 21 and a discharging end 22, the feeding end 21 is generally positioned above the discharging end 22, the vibration force generated by the vibration mechanism 3 drives the chute 2 to vibrate, and materials in the chute 2 smoothly move in the chute 2 under the action of the vibration force to enter a feeding port of downstream equipment from the discharging end 22 of the chute 2, so that the purpose of discharging is achieved. I.e. without changing the inclination of the chute 2, the discharge rate is increased and the material is prevented from being retained in the chute 2 as much as possible.

So configured, the movable member 43 is compressed by the first spring 44 or the second spring 45 to provide elastic force as a buffering force, regardless of inward or outward movement in the extending direction of the buffering cylinder body 41.

Preferably, the first spring 44 and the second spring 45 may be fixedly connected or welded to the movable member 43, and whether the movable member 43 moves inward or outward in the extending direction of the buffer cylinder body 41, one of the first spring 44 and the second spring 45 is compressed, and the other one thereof is extended, so that the first spring 44 and the second spring 45 simultaneously provide elastic force as a buffer force to increase the buffer performance of the buffer mechanism 4.

Specifically, the movable member 43 is a movable nut, and the movable nut is connected to the output member 42 by a screw. So arranged, the movable member 43 and the output member 42 can be easily attached and detached.

Further, a double stack of self-locking shims 46 is sandwiched between the moveable nut and the screw. The double stack of self-locking shims 46 ensures that even under high vibration conditions or repeated use over time, i.e. relative rotation of the moveable nut and screw is avoided, resulting in separation of the moveable nut from the screw.

As shown in fig. 5, in another embodiment, the buffer cylinder body 41 has a buffer chamber 411 therein, the buffer chamber 411 is internally and hermetically connected with a piston 47, and the piston 47 is slidably connected in the buffer chamber 411, the output member 42 is connected with the piston 47, and the outer peripheral wall of the output member 42 is slidably and hermetically connected with the buffer cylinder body 41. I.e. the buffer cylinder block 41, the piston and the output member 42 cooperate at this time to be considered as a gas spring. Specifically, the piston 47 may divide the buffer chamber 411 into a first chamber 4111 and a second chamber 4112, where the first chamber 4111 and the second chamber 4112 are respectively a closed chamber, and the inside of the first chamber 4111 and the inside of the second chamber 4112 are respectively filled with gas having an equal pressure. The outer peripheral wall of the output member 42 is slidably and sealingly connected to the cylinder block 41 so as to form a closed chamber in cooperation with the piston 47 in the second chamber 4112. In the initial state, the piston 47 may be considered to be in the middle position of the buffer chamber 411, that is, the volumes of the first chamber 4111 and the second chamber 4112 are equal, and the pressures of the gases in the two chambers are equal. When the piston 47 starts to move in the buffer chamber 411, the volumes of the first chamber 4111 and the second chamber 4112 change, that is, the gas pressure in one chamber becomes large, and the gas pressure in the other chamber becomes small, so that a pressure difference is finally generated, and the buffer effect of the gas spring or the buffer mechanism is realized.

Specifically, the output member 42 and the piston 47 may be connected by a threaded connection, a clamping connection, a welding connection, a bolting connection, or the like.
