Description

Chute cushioning device

Technical field

The utility model relates to a kind of chute cushioning device, especially a kind of chute cushioning device for materials-handling technology field.

Background technology

The chute normally groove transporting thing from high to lower on the ground, inner face is smooth, and thing can be slid down automatically, is the very common equipment in ore dressing plant.Therefore, usual chute all can have following problem: chute inner face is smooth, material slides from high to low, cause the speed of material larger, when material leaves the follow-up splicing equipment that chute enters as disintegrating machine, the speed of material is very large, can produce larger impact, follow-up splicing equipment badly broken to splicing equipment.Simultaneously material operation at a high speed in chute, also can have an impact to the liner plate of chute, and liner plate also can serious wear, reduces chute service life.Therefore also do not have a kind of structure simple in prior art, cost is low, reliable operation, easy examine and replace and slow down the chute cushioning device of chute and the damage of follow-up splicing equipment.

Utility model content

Technical problem to be solved in the utility model is to provide that a kind of structure is simple, and cost is low, reliable operation, easy examine and replace and slow down the chute cushioning device of chute and the damage of follow-up splicing equipment.

For solving the problems of the technologies described above the chute cushioning device that the utility model adopts, comprise chute and Buffer Unit, described Buffer Unit comprises buffer board and elastic component, one end and the chute of described buffer board are rotatably connected, the other end is free end, described elastic component one end is connected with buffer board, and the other end is connected with chute.

Further, described elastic component is spring.

Further, described Buffer Unit is two groups or more than two.

Further, the stiffness factor of described last group of Buffer Unit spring is greater than the stiffness factor of rear pool of buffer assembly spring.

Further, the buffer board of two adjacent groups Buffer Unit is connected to the both sides of chute.

Further, the scope of the included angle A of described buffer board and chute center line is 30 degree to 70 degree.

The beneficial effects of the utility model: when material slides to Buffer Unit position at a high speed along chute, material promotes buffer board Compress Spring, a part of kinetic energy of material converts the elastic potential energy of spring to, in conversion process of energy, the speed of material slows down, such buffer board carries out upper and lower radian swing by the active force between material and upper spring, and buffer board absorbs the energy of material in swing process, effectively reduces the speed that material falls.Effectively can slow down the impact of material to chute lining board and follow-up splicing equipment by this buffer unit, whole process completes automatically, saves cost of labor, protects chute and follow-up splicing equipment better.Device is simple, convenient maintenance and replacement, improves the service life of chute and follow-up splicing equipment, reduces cost of labor, greatly reduces enterprise's production cost, for enterprise creates economic benefit.

Detailed description of the invention

Below in conjunction with accompanying drawing, the utility model is described in further detail.

As depicted in figs. 1 and 2, chute of the present utility model (1) buffer unit, it is characterized in that: comprise chute (1) and Buffer Unit, described Buffer Unit comprises buffer board (2) and elastic component, one end and the chute (1) of described buffer board (2) are rotatably connected, the other end is free end, and described elastic component one end is connected with buffer board (2), and the other end is connected with chute (1).When material slides to Buffer Unit position at a high speed along chute (1), material promotes buffer board (2) Compress Spring (3), a part of kinetic energy of material converts the elastic potential energy of spring (3) to, in conversion process of energy, the speed of material slows down, such buffer board (2) carries out upper and lower radian swing by the active force between material and upper spring (3), buffer board (2) absorbs the energy of material in swing process, effectively reduces the speed that material falls.Described elastic component can be spring (3), the industrial conventional elastic element such as flexure strip.

As a kind of preferred embodiment, described elastic component is spring (3).Spring (3) structure is simple, and institute takes up space little, is convenient to connect.

Described Buffer Unit is two groups or more than two.Many group bolsters are adopted to strengthen buffering effect

The stiffness factor of described last group of Buffer Unit spring (3) is greater than the stiffness factor of rear pool of buffer assembly spring (3).Last like this group Buffer Unit is comparatively large to the cushioning effect of material, and the cushioning effect of latter a group is little, and the stepwise speed being conducive to material is successively decreased.

The buffer board (2) of two adjacent groups Buffer Unit is connected to the both sides of chute (1).To stagger about can making two adjacent groups Buffer Unit like this setting, prevent the material speed only having chute (1) side from reducing, and opposite side can not get situation about slowing down

Described buffer board (2) is 30 degree to 70 degree with the scope of the included angle A of chute (1) center line.But buffering effect is best when the included angle A of buffer board (2) and chute (1) center line gets aforementioned angular.

Embodiment:

The present embodiment adopts two groups of buffer units, staggers setting in front and back.Upper buffer board (2) left end is fixed, and right-hand member is not fixed, and carries out upper and lower radian swing by the active force between material and upper spring (3); Lower buffer board (2) right-hand member is fixed, and left end is not fixed, and carries out upper and lower radian swing by the active force between material and lower spring (3).Angle between upper buffer board (2) and mass transport direction is 30 degree to 70 degree, and the angle between lower buffer board (2) and mass transport direction is 30 degree to 70 degree.When material is when chute (1), because active force mutual between material and spring (3) is larger, spring (3) is caused to be compressed, material passes through chute (1) through upper and lower buffer board (2), when entering follow-up splicing equipment, the speed of material significantly reduces, thus also greatly reduces the impact of follow-up splicing equipment.
