As shown in fig. 1, the bin assembly provided by the invention comprises a bin 100 and a feeding device 300, wherein the bin 100 comprises a bin main body 110 and a bin bottom shell 120, a feeding hole is formed in the upper end of the bin main body 110, the lower end of the bin main body 110 is connected with the bin bottom shell 120, and the inside of the bin main body 110 is communicated with the inside of the bin bottom shell 120. The discharge port of the feeding device 300 is opposite to the feed port of the bin main body 110, and the feeding device 300 is used for feeding the material into the bin main body 110, and preferably, the feeding position of the feeding device 300 is located at the center position of the bin main body 110. Be provided with refining device 130 in the feed bin drain pan 120, refining device 130 preferably sets up in the feed bin drain pan 120, and be close to feed bin main part 110 with the junction of feed bin drain pan 120, refining device 130 is right the material in the feed bin main part 110 has the effect of bearing, so that when need not feed down stream, the material can not fall into in the feed bin drain pan 120, can store a certain amount of material in the feed bin main part 110, simultaneously, when needs feed, refining device 130 can guarantee that the even scattering of material arrives in the feed bin drain pan 120, avoid the material to pile up in the feed bin main part 110 and cause the jam.

Specifically, the bin main body 110 is in a cylindrical structure, and the bin main body 110 is in a cylindrical structure with an upper end smaller than a lower end, that is, the cross-sectional area of the bin main body 110 gradually increases from top to bottom, so that the appearance of the bin main body 110 is in an upright cone shape, or the bin main body 110 can also be in a structure such as a truncated cone or a prismatic table. The upper end of the bin bottom shell 120 is adapted to the lower end of the bin main body 110, and is in sealing connection, the lower end of the bin bottom shell 120 is closed, and a discharge port is provided on the sidewall of the bin bottom shell 120, and the material can be transported out through the discharge port under the action of the material conveying device (described in detail below).

Compared with a cylindrical bin main body or a funnel-shaped bin main body in the prior art, the bin provided by the invention has the following advantages when adopting a positive conical structure: when the material falls into the feed bin, even the pan feeding mouth is close to the top edge of feed bin main part, because the below space grow gradually, the drop point after the material falls also can keep enough distance from the feed bin lateral wall for the material can evenly to the landing or roll down all around, and can not contact the lateral wall of feed bin main part and then form the heap in lateral wall department easily, like cylindrical or funnel-shaped feed bin main part in the prior art. This advantage is even more pronounced when the feed opening is located at the centre point of the silo body.

When the bin is used for throwing dry fiber materials, the fibers are easy to intertwine and accumulate due to poor flowability of the fiber materials, so that when the bin main body in the prior art is adopted, the fiber materials can be always and quickly accumulated to the height of a feed inlet by means of the side wall at one side, and even the position of a discharge hole of a feeding device, so that the smooth throwing of the materials is influenced; when the bin main body is adopted, the adverse phenomenon is thoroughly eliminated.

As shown in fig. 2, the refining device 130 includes a plurality of rolling shafts 131, preferably 3 to 4, the rolling shafts 131 are provided with a plurality of shifting teeth 132, the shifting teeth 132 are distributed along the axial direction of the rolling shafts 131, and the shifting teeth 132 extend in a plurality of directions in the radial direction of the rolling shafts 131. The plurality of rolling shafts 131 are disposed at a distance from each other to prevent the shifting teeth 132 from interfering with each other when they are rotated. The rolling shaft 131 is rotatably disposed near the lower portion of the bin main body 110, and when in operation, the rolling shaft 131 rotates simultaneously, and breaks up the material in the bin main body 110 through the poking teeth 132, so that the material is scattered into the bin bottom shell 120. Preferably, the rotation speeds of the plurality of rolling shafts 131 are different from each other, so as to ensure that the materials are scattered as much as possible when the rolling shafts 131 rotate, so that the materials fall down uniformly. Further, the rotation speeds and the rotation directions of the rolling shafts 131 are different, so that the materials are further ensured to be sufficiently scattered. The rolling shafts 131 may be provided with different driving devices to ensure that the rotation speed and/or the rotation direction of each rolling shaft 131 are different, or a plurality of rolling shafts 131 use the same driving device, and then the driving device drives the rolling shafts 131 to rotate simultaneously through a transmission device, and different transmission ratios may be set in the transmission devices of the different rolling shafts 131 to ensure that the rotation speeds and/or the rotation directions of the rolling shafts are different, and preferably, the transmission device may be a chain transmission, a belt transmission, a gear transmission or the like.

As shown in fig. 1, in order to further ensure that the material is not accumulated in the bin main body 110 excessively, the material refining device 130 is preferably disposed obliquely, i.e., the rolling shaft 131 is disposed at an angle with respect to the horizontal plane, so that the material can move along the axial direction of the rolling shaft 131 under the action of gravity or has a tendency to move along the axial direction of the rolling shaft 131, so that the material moves more easily following the rotation of the rolling shaft 131 when the rolling shaft 131 rotates.

The lower extreme of feed bin 100 is provided with material conveyer 200, a portion of transmission 200 is located in feed bin drain pan 120, material in the feed bin main part 110 passes through refining device 130 is scattered to in the feed bin drain pan 120, by material conveyer 200 passes through the discharge gate is carried away. Preferably, the material conveying device 200 is a screw conveying device, and includes a conveying screw 210 and a driving part 220, wherein the driving part 220 is preferably located at a side far from a discharge hole of the bin bottom shell 120, and the driving part 220 is preferably located at an outer side of the bin bottom shell 120. The driving part 220 is connected with the conveying screw 210 and drives the conveying screw 210 to rotate, and the conveying screw 210 conveys away materials through rotation. Preferably, the conveying screw 210 is disposed parallel to the rolling shaft 131, further, the bottom of the bin bottom shell 120 is an arc-shaped cylindrical structure adapted to the conveying screw 210, and the axis of the arc-shaped cylindrical structure and the axis of the conveying screw 210 are disposed parallel to the conveying screw 210 in the axial direction, preferably, the axis of the arc-shaped cylindrical structure and the axis of the conveying screw 210 are collinear. When the conveying screw 210 is obliquely disposed, the conveying direction is obliquely upward, in this case, the obliquely disposed conveying screw 210 and the bottom of the bin bottom shell 120 enable the material to move obliquely downward (away from the direction of the discharge port) along the axial direction of the conveying screw 210 under the action of self gravity, or have a tendency to move obliquely downward along the axial direction of the conveying screw 210, so that the material is not easy to accumulate at the discharge port to cause blockage when the conveying screw 210 rotates. .

As shown in fig. 3, in this embodiment, the rolling shaft 131 is driven by the driving part 220 of the material conveying device 200, so that the rolling shaft 131 and the conveying screw 210 rotate synchronously, so that the material can be conveyed away by the conveying screw 210 in time while blanking, and the situation that the material falls into the bin bottom shell 120 but the conveying device 200 is not started to cause the material to be accumulated in the bin bottom shell 120 is avoided. Further, the driving part 220 drives the rolling shaft 131 to rotate through a chain or belt transmission, and a tension pulley 133 is provided between sprockets or pulleys on the rolling shaft 131 in order to secure reliability of power transmission. In order to ensure the safety of the operation, a protective cover (not shown) is provided on the outside of the transmission between the driving part 220 and the rolling shaft 131, so as to prevent the operator from being injured by the operation error.

The discharge port on the bin bottom shell 120 is communicated with a material conveying channel 400, and the material conveying channel 400 is preferably in a cylindrical structure matched with the conveying screw 210. The material transfer passage 400 extends in the axial direction of the conveyor screw 210, and the conveyor screw 210 extends into the material transfer passage 400. Material is conveyed into the material transfer passage 400 as the conveyor screw 210 rotates.

Preferably, in order to further prevent accumulation of material at the discharge port on the bin bottom shell 120, the material transfer passage 400 is provided with a transition section at a position near the end connected to the discharge port, and the cross-sectional area of the transition section is gradually reduced from the position of the discharge port until being equal to the cross-sectional area of the rest of the material transfer passage 400. That is, the area of the outlet may be larger than the cross-sectional area of the normal portion of the material transfer passage 400, and the two may be engaged by the transition section. The meaning of this transition section is that when more material is transported by the conveyor screw 210 to the location of the discharge port, if the area of the discharge port is small, for example, equal to the cross-sectional area of the normal portion of the material transfer passage 400, it means that the gap between the conveyor screw 210 and the inner wall of the material transfer passage 400 is small from the discharge port, and excessive material is liable to form a blockage at the discharge port; by providing a larger discharge port and a transition section with a gradually smaller cross-sectional area, the material can be temporarily stored or let back in a larger gap between the conveying screw 210 and the inner wall of the transition section, so that the blockage is not caused.

Specifically, the transition section may include a slope 410 inclined with respect to the axis of the material transfer passage 400, where the slope 410 is configured to allow the material to enter the material transfer passage 400 through a region of gradually decreasing cross-sectional area of the passage, where the junction between the material transfer passage 400 and the material outlet is not suddenly decreased, so that the material does not form a pile at the material outlet when entering the material transfer passage 400.

Further, the cross section of the material conveying channel 400 is U-shaped, that is, the bottom of the material conveying channel 400 is an arc-shaped groove-shaped structure with the same shape as the bottom of the bin bottom shell 120, for example, a semi-cylindrical shape, the top of the material conveying channel 400 is a rectangular groove-shaped structure, the arc-shaped groove-shaped structure and the rectangular groove-shaped structure are spliced into a complete cylindrical structure, and the splicing surfaces of the arc-shaped groove-shaped structure and the rectangular groove-shaped structure are parallel to the axis of the material conveying channel 400. The inclined surface 410 is formed at the top of the material transfer passage 400. Moreover, the U-shaped cross section of the material conveying channel 400 is configured such that a gap between the upper side of the conveying screw 210 and the inner wall of the material conveying channel 400 is enlarged, so that a certain material containing space is formed, so that materials can be avoided from being led to the material containing space, and the excessive materials are prevented from blocking after entering the material conveying channel 400.

According to the bin assembly provided by the invention, the bin main body 110 is arranged to be of a structure with a small upper end and a large lower end, so that materials can be effectively prevented from being accumulated at the contact position of the inner wall of the bin main body 110, and the materials can fall more smoothly. The provision of the refining apparatus 130 ensures that the material can be evenly scattered and further ensures that the material is not deposited in the bin body 110.

It is easy to understand by those skilled in the art that the above preferred embodiments can be freely combined and overlapped without conflict.

It will be understood that the above-described embodiments are merely illustrative and not restrictive, and that all obvious or equivalent modifications and substitutions to the details given above may be made by those skilled in the art without departing from the underlying principles of the invention, are intended to be included within the scope of the appended claims.
