Detailed description of the invention
Understand for technical characterictic of the present utility model, object and effect being had more clearly, now contrast brief description of the drawings detailed description of the invention of the present utility model.Wherein, identical parts adopt identical label.
Fig. 1 is according to the structural representation of a kind of wood chip bucket elevator belt tensioning device of a specific embodiment of the present utility model; Fig. 2 is the part-structure schematic diagram of the wood chip bucket elevator bottom shown in Fig. 1; Fig. 3 is the structural representation of the square-shaped hopper shown in Fig. 1.Shown in Fig. 1-3, the utility model provides a kind of wood chip bucket elevator, it comprises casing 1, be arranged at the actuating device 2 in described casing 1, tightening device 3 moving up and down and be provided with the belt 4 of hopper, described casing 1 bottom is provided with inlet point 11, top is provided with discharging opening 12, described inlet point 11 is connected with a square-shaped hopper 5 by pipeline, described tightening device 3 is provided with the auricle 31 extending to outside described casing 1, described casing 1 is provided with locating plate 13 above described auricle 31, described auricle 31 is connected by slide bar 6 with described locating plate 13, the each sidewall of described square-shaped hopper 5 has respectively been horizontally disposed with at least one bar magnet 51.
Said as background technology, existing bucket elevator, tightening device 3 position is in use fixed, and in the time using bucket elevator to transport wood chip material, because the size of wood chip material is inhomogeneous, particularly in the time being mixed with metallic impurity in wood chip material, be easy to cause in bucket elevator exit position congested, like this, when the outlet discharge that occurs bucket elevator top not in time, cause congestedly, cylinder continues the upwards situation of belt elevator, is just easy to cause the belt fracture of bucket elevator.
For fear of this situation, the utility model improves on existing bucket elevator basis.The utility model says that the wood chip bucket elevator providing utilizes nut that described slide bar 6 is fixed on described locating plate 13, before wood chip bucket elevator is started working, described tightening device 3 is under the effect of self counterweight, hang on described slide bar 6 by described auricle 31, like this by adjusting the length of described slide bar 6, can make described tightening device 3 make belt keep tensioning state under the effect of self counterweight.When the outlet discharge that occurs wood chip bucket elevator top not in time, cause congested, cylinder continues the upwards situation of belt elevator, if the suffered tensile force of belt is greater than the gravity that self counterweight of described tightening device 3 produces, described tightening device 3 can upwards produce displacement along described slide bar 6 under belt drives, so just can avoid excessive belt tension to pull apart belt, in the time that the outlet on wood chip bucket elevator top recovers unobstructed, described tightening device 3 just can fall back to described slide bar 6 bottoms under self counterweight effect.So, by ensureing that described tightening device 3 has a mobile space to top offset, just can be stressed when excessive at belt, make described tightening device 3 follow belt to top offset, thereby avoid belt fracture.
In addition, in order to get rid of the metallic impurity in wood chip material, avoid bucket elevator exit position to occur congested as far as possible, by described bar magnet 51 being set at described square-shaped hopper 5 sidewalls, just can be when chip raw material falls under gravity into described square-shaped hopper 5, scatter in the process dropping in chip raw material, metallic impurity are wherein adsorbed.Four sidewalls of described square-shaped hopper 5 are flat board, so just can be convenient to purchase bar magnet 51 finished products and install.Described bar magnet 51 can be greater than 4/5ths of its length of side in the installation site of described sidewall, can make like this magnetic field of described bar magnet 51 form enough coverings to the space in described square-shaped hopper 5, thereby ensure the adsorption removal to metallic impurity.
In a preferred embodiment, each described sidewall is uniformly distributed in vertical direction and is fixed with three described bar magnets 51.Can further make like this magnetic field of described bar magnet 51 form enough coverings to the space in described square-shaped hopper 5, thereby ensure the adsorption removal to metallic impurity.
In a preferred embodiment, described locating plate 13 bottoms are provided with stop spring 7, described stop spring 7 can be enclosed within outside described slide bar 6, the effect of described stop spring 7 is to avoid described tightening device 3 when to top offset, if displacement is excessive, directly bump against described casing 1 with larger speed, thereby described casing 1 is caused to damage, described stop spring 7 only needs, by described auricle 31, described tightening device 3 is produced to an elastic buffer, therefore, its length only need to be greater than the distance of described locating plate 13 to the top edge of described casing 1 opening, certain elastic buffer can be provided, those skilled in the art are to be understood that, the effect of the spring in the Chinese patent CN202765730U that described stop spring 7 is mentioned from background technology is completely different.
In a preferred embodiment, described locating plate 13 is provided with the check plate (not shown) of pointing to described auricle 31.Described check plate can be iron rod or the L shaped steel disc being welded on described locating plate 13, its effect be equally for fear of described tightening device 3 when to top offset, if displacement is excessive, directly bump against described casing 1 with larger speed, thereby described casing 1 is caused to damage, therefore, its length is same only need to be greater than the distance of described locating plate 13 to the top edge of described casing 1 opening.
Certainly, described check plate and described stop spring 7 can be set on described locating plate 13 simultaneously, the length of described check plate and described stop spring 7 is greater than the distance of described locating plate 13 to the top edge of described casing 1 opening, the length of described stop spring 7 is greater than the length of described check plate, so just can utilize the buffering of described stop spring 7, avoid described tightening device 3 in top offset process, described auricle 31 and described check plate generation rigid collision, thus may cause damage to described tightening device 3.
A kind of wood chip bucket elevator provided by the utility model, it can be before wood chip enters inlet point, metallic impurity are wherein adsorbed, and the wood chip material that minimizing is mixed with metallic impurity causes congested situation at bucket elevator discharging opening, in addition, there is bucket elevator outlet discharge not in time, cause congestedly, cylinder continues upwards belt elevator, and belt is stressed when excessive, can make tightening device follow belt to top offset, thereby avoid belt fracture.
Although it will be appreciated by those skilled in the art that the utility model is to be described according to the mode of multiple embodiment, be not that each embodiment only comprises an independently technical scheme.For the purpose of in specification sheets, so narration is only used to know; those skilled in the art should make specification sheets as a wholely to be understood, and regard technical scheme related in each embodiment as the mode that can mutually be combined into different embodiment understand protection domain of the present utility model.
