Description

Technical Field

[0001] The utility model relates to the technical field of chute anti-blocking, in particular to a device for preventing blocking of a falling material chute. Background Art

[0002] Due to the diversity of material transportation, when the moisture content of the material is too high, the material flow is poor and it is easy to adhere to the bottom of the chute, which can easily lead to poor material discharge due to material accumulation at the bottom of the chute, causing large-scale blockage of the chute. The wall blockage affects the material transportation efficiency and seriously affects the safe and stable operation of the unit. It is difficult to clean up the accumulated materials in the chute, which increases the labor intensity of the workers. Utility Model Content

[0003] The utility model aims to overcome the shortcomings of the prior art and provide a device for preventing blocking of a material dropping chute which has stable operation and good anti-blocking effect.

[0004] The utility model is realized in this way: a device for preventing blocking of a material dropping chute comprises an opening arranged on the chute, the chute is provided with a clearing scraper for clearing blockage, and the chute is provided with a driving device for driving the clearing scraper to move.

[0005] The chute is provided with a driving device for driving the blockage-clearing scraper to move through the opening.

[0006] The driving device adopts a rodless cylinder or a hydraulic cylinder.

[0007] The slide block of the rodless cylinder or hydraulic oil cylinder penetrates into the opening and is connected with the blockage clearing scraper.

[0008] The thickness of the slider is the same as the thickness of the chute wall (the opening depth of the chute wall). The blockage-clearing scraper is installed on the slider so that the blockage-clearing scraper can be attached to the chute wall, which is convenient for cleaning the blockage.

[0009] The cross section of the blockage clearing scraper is a herringbone structure, which facilitates the clearing scraper to clean the blockage on the chute wall when the blockage clearing scraper moves left and right.

[0010] The rodless cylinder is installed on the chute through a bracket.

[0011] An observation window is provided on the chute.

[0012] The longitudinal section of the slider is a trapezoid, which is narrow at the upper end and wide at the lower end. The slider can output the material in the opening when it moves left and right.

[0013] The installation direction of the blockage clearing scraper can be parallel to the direction of material flow, and can also be perpendicular to the direction of material flow.

[0014] When the device is in use, the driving device can be started regularly, and the driving device drives the slider and the cleaning scraper to move back and forth, and the cleaning scraper scrapes off the materials attached to or blocked at the bottom of the chute.

[0022] Example 1: Figures 1 to 5 As shown, a device for preventing a material drop chute from being blocked comprises an opening 7 arranged on the chute 2, the chute 2 is provided with a blockage clearing scraper 3 for clearing blockage, and the chute 2 is provided with a driving device 5 for driving the blockage clearing scraper 3 to move.

[0023] The difference between Example 2 and Example 1 is that the chute 2 is provided with a driving device 5 through the opening 7 for driving the clearing scraper 3 to move.

[0024] The difference between Example 3 and Example 2 is that the driving device 5 adopts a rodless cylinder.

[0025] The difference between Example 4 and Example 3 is that the slider 8 of the rodless cylinder penetrates into the opening 7 and is connected to the blockage-clearing scraper 3 .

[0026] The difference between Example 5 and Example 4 is that the thickness of the slider 8 is the same as the thickness of the chute wall 6 (the opening depth of the chute wall), and the blockage-clearing scraper installed on the slider can make the blockage-clearing scraper stick to the chute wall 6, which is convenient for cleaning the blockage.

[0027] The difference between Example 6 and Example 5 is that the cross section of the blockage clearing scraper 3 is a herringbone structure, which facilitates the clearing of blockages on the chute wall when the blockage clearing scraper moves left and right.

[0028] The difference between Example 7 and Example 6 is that the rodless cylinder is installed on the chute through the bracket 4.

[0029] The difference between Example 8 and Example 7 is that an observation window 1 is provided on the chute.

[0030] The difference between Example 9 and Example 8 is that the longitudinal section of the slider is a trapezoid, which is narrow at the upper end and wide at the lower end, and the slider can output the material in the opening when it moves left and right.

[0031] The difference between Example 10 and Example 9 is that the installation direction of the blockage clearing scraper is parallel to the direction of material flow.

[0032] The difference between Example 10 and Example 9 is: Figure 6 The installation direction of the blockage clearing scraper is perpendicular to the direction of material flow.

[0033] When the device is in use, the driving device can be started regularly, and the driving device drives the slider and the cleaning scraper to move back and forth, and the cleaning scraper scrapes off the materials attached to or blocked at the bottom of the chute.
