Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention.

A feeding apparatus 100 according to an embodiment of the present invention is described below with reference to fig. 1, the feeding apparatus 100 of an embodiment of the present invention including: a shell 1 and a refining device 2. Specifically, a feeding channel 10 is formed in the shell 1, a material conveying plate 11 which is obliquely arranged is arranged in the shell 1, and materials enter the feeding channel 10 and then fall on the material conveying plate 11 for conveying; the refining device 2 comprises a pressure plate 21, the upper end of the pressure plate 21 is pivoted with the shell 1, and when the pressure plate 21 is naturally placed, a certain gap is formed between the lower end of the pressure plate 21 and the material conveying plate 11.

In the embodiment of the utility model, as shown in fig. 1, a feeding channel 10 is formed in a housing 1, when in actual use, a material enters the feeding channel 10 from the upper end of the housing 1, and then flows downwards under the limitation of a material conveying plate 11 and other peripheral walls of the housing 1, the upper end of a pressure plate 21 is pivoted with the housing 1, when the pressure plate 21 is naturally placed, the pressure plate 21 is generally in a vertical state, a certain gap is formed between the lower end of the pressure plate 21 and the material conveying plate 11, and the material flows downwards under the limitation of the gap.

When the layer height of the material flow is smaller than the gap, the material flow is generally small and is gathered together to flow into a subsequent processing device (such as a color selector), and the subsequent processing device can also easily deal with the material flow without performing refining treatment. When the layer height of the material flow is larger than the gap, the flow rate is relatively large, if the material is not subjected to material refining treatment, the material with large flow rate is gathered together and flows into subsequent treatment equipment (such as a color sorter), and the problem that the treatment task is heavy exists in a part of the subsequent treatment equipment. Therefore, the arrangement of the material pressing plate 21 in the embodiment of the present invention makes the material flow with a large flow rate not flow down from the position in time under the restriction of the material pressing plate 21, and further flows to other places in the gap between the material pressing plate 21 and the material conveying plate 11, so that the material flow uniformly flows down from the gap between the material pressing plate 21 and the material conveying plate 11. When the flow rate of the material continues to increase, the material with large flow rate is squeezed between the pressure plate 21 and the material conveying plate 11, so that the material flow pushes the pressure plate 21 to rotate outwards, the gap between the pressure plate 21 and the material conveying plate 11 is enlarged, and the material flows downwards in the gap between the pressure plate 21 and the material conveying plate 11 in an evenly distributed manner after the gap is enlarged. Of course, when the flow rate of the material is reduced, the force of the material pressing plate 21 outwards is reduced, and then the material pressing plate 21 rotates until the pressure of the material pressing plate 21 on the material is balanced with the supporting force provided by the material, in this state, as described above, due to the limit of the material pressing plate 21, the flow rate of the material in the area where the material flow is large is limited, and then the material flows to other places in the gap, so as to ensure that the flow rate of the material flowing downwards in the whole gap is consistent.

In summary, in the embodiment of the present invention, the gap formed between the pressing plate 21 and the material conveying plate 11 is utilized to perform the function of material flowing and homogenizing. Specifically, when the material flow is large, the material pushes the pressure plate 21 outwards to enlarge the gap, when the material flow is small, the pressure plate 21 rotates inwards by the gravity of itself to reduce the gap, so that the material flow cannot directly flow out at the position with large flow, the material at the position with large flow moves to the position with small flow, the material between the pressure plate 21 and the material conveying plate 11 is uniformly distributed, and finally the material uniformly flows downwards. The automatic feeding device is simple in structure, and ensures that materials are uniformly discharged after passing through the feeding channel 10 by utilizing the negative feedback automatic adjustment of the material pressing plate 21.

Therefore, the materials can uniformly and smoothly enter the subsequent processing equipment (such as a color sorter) through the material homogenizing treatment of the feeding device 100, so that the load of the subsequent processing equipment (such as the color sorter) can be reduced, and the processing efficiency and the processing quality of the subsequent processing equipment (such as the color sorter) on the materials can be improved.

Specifically, in an embodiment of the present invention, the pressure plate 21 may be pivotally connected to the housing 1 through a hinge.

The material feed plate 11 may be formed as part of the housing 1 as shown in fig. 1. Of course, the material feed plate 11 can also be a separate part which is arranged inside the housing 1.

According to the feeding device 100 of the embodiment of the utility model, a balancing weight 22 is arranged on one surface of the material pressing plate 21 away from the material conveying plate 11. In the above embodiment, it can be seen that in the embodiment of the present invention, the self-gravity of the pressure plate 21 is mainly used to provide the pressure on the material toward the side of the material conveying plate 11, so as to ensure that the material with a large flow rate cannot directly rush through the pressure plate 21 and then gather together to flow downward. However, in practical use, enough pressure cannot be provided sometimes only by the self gravity of the pressing plate 21, and as shown in fig. 2, the pressing plate 21 is provided with the counter weight 22 on the side away from the material conveying plate 11, the counter weight 22 is used to increase the pressure transmitted to one side of the material conveying plate 11, so as to provide better pressure, and meanwhile, the pressing plate 21 is generally pivoted on the casing 1 and is not easy to replace, and the counter weight 22 can be replaced with different specifications according to requirements to meet the feeding requirements of different materials.

According to the feeding device 100 of the embodiment of the utility model, the balancing weight 22 is connected to the pressure plate 21 through the adjusting rod 23. In the above embodiment, it can be known that the balancing weight 22 can increase the pressure of the pressing plate 21 towards one side of the material conveying plate 11, and then can change according to the feeding of different materials, for example, when sorting small-particle materials, the weight of the balancing weight 22 can be increased, and then the gap between the pressing plate 21 and the material conveying plate 11 is reduced, so as to ensure that the whole gap is filled with materials and then evenly falls, and the falling flow of the materials can be controlled by the arrangement. However, when a large amount of granular materials are needed, the weight of the counterweight 22 can be reduced, so that the pressure applied to the materials by the pressure plate 21 is reduced, the pressure plate 21 moves outwards under the pushing of the materials, and the gap between the pressure plate 21 and the material conveying plate 11 is increased, so that the materials can easily flow downwards and are not clamped in the gap between the pressure plate 21 and the material conveying plate 11. In the embodiment of the present invention, the counterweight 22 is connected to the pressure plate 21 through the adjusting rod 23, so that the length of the adjusting rod 23 can be utilized to increase the moment transmitted by the counterweight 22 to the pressure plate 21, and the weight of the counterweight 22 or the position of the counterweight 22 on the adjusting rod 23 can be adjusted to adjust the acting force transmitted by the counterweight 22 to the pressure plate 21 in actual use. Therefore, the use is more convenient, and the pressure of the material pressing plate 21 on the material is more convenient to adjust.

Specifically, according to the feeding device 100 of the embodiment of the present invention, the adjusting rod 23 is perpendicular to the plane where the pressure plate 21 is located. Referring to fig. 2, when the adjusting rod 23 is perpendicular to the plane of the pressure plate 21, the moment transmitted from the weight 22 to the pressure plate 21 is the largest, and thus the force that can be transmitted is the largest, so that the lightest weight 22 can be used under the same force. Certainly, the adjusting rod 23 can also present other included angles perpendicular to the plane where the pressure plate 21 is located, but the included angle between the adjusting rod 23 and the pressure plate 21 on the side of the pivot axis of the pressure plate 21 is generally an acute angle or a right angle, so that the center of gravity of the whole material refining device 2 can face one side of the material conveying plate 11, so that the pressure plate 21 has a tendency of moving towards one side of the material conveying plate 11, a small gap is always kept between the pressure plate 21 and the material conveying plate 11, and the phenomenon that the gap between the pressure plate 21 and the material conveying plate 11 is too large, which causes the material to flow out from the gap without refining is avoided.

Specifically, according to the feeding device 100 of the embodiment of the present invention, an opening 12 is provided on one side of the housing 1 opposite to the adjusting rod 23, and one end of the adjusting rod 23 passes through the opening 12 and then extends to the outside of the housing 1. Referring to fig. 3, the pressure plate 21 moves toward the opening 12 under the extrusion of the material, so that the adjusting rod 23 also moves toward the opening 12, the opening 12 is disposed to enable the adjusting rod 23 to move smoothly, the moving range of the adjusting rod 23 is prevented from being interfered/limited, and the pressure plate 21 can rotate freely according to the actual situation.

Specifically, the balancing weight 22 is connected with the adjusting rod 23 through a thread. The balancing weight 22 is connected with the adjusting rod 23 through a thread, so that the balancing weight 22 can be quickly mounted and dismounted, and the position of the balancing weight 22 on the adjusting rod 23 can be adjusted, and the use is convenient. Of course, the counterweight block 22 and the adjusting rod 23 can also be connected by other methods, such as clamping, etc., and the specific connection mode of the counterweight block 22 and the adjusting rod 23 can be determined as required on the premise of being convenient for adjusting the position of the counterweight block 22 on the adjusting rod 23, which should not constitute the limitation of the present application.

Specifically, according to the feeding device 100 of the embodiment of the present invention, the housing 1 may further be provided with a viewing window 13. Referring to fig. 3, a viewing window 13 is provided to facilitate viewing of material in the feed channel 10, sampling operations, and the like.

Specifically, as shown in fig. 3 and 4, the feeding device 100 according to the embodiment of the present invention includes a material distribution assembly 3, wherein the material distribution assembly 3 includes a bottom plate 31 and six material distribution plates 32, the six material distribution plates 32 are spaced on the bottom plate 31 to define five material distribution channels 33, and the five material distribution channels 33 are respectively communicated with the feeding channel 10 formed by the housing 1. Of course, the number of the material distribution plates 32 is not limited to six in fig. 3 and 4. The number of the material separating plates 32 can be set to any number according to the requirement as long as the material separating function can be achieved, and the material separating plate is only used for illustration and is not used for limiting the utility model.

It can be understood from the above that the bottom plate 31 can support the plurality of material distributing plates 32, and define a plurality of material distributing channels 33 with the plurality of material distributing plates 32, the material can enter the material feeding channel 10, and flow to the plurality of material distributing channels 33 through the material feeding channel 10, and the material distributing channels 33 can disperse the material and then flow to the material processing bin, so that the material can uniformly, dispersedly and smoothly enter the material processing equipment.

In the related art, the feeding hopper of the color sorter has a plurality of feeding channels, and according to the feeding device 100 of the embodiment of the present invention, the plurality of material distributing plates 32 are arranged on the bottom plate 31 at intervals to define a plurality of material distributing channels 33, so that the material can flow into the plurality of material distributing channels 33 for dispersion after flowing out from the feeding channel 10, and thus the material can uniformly, dispersedly and smoothly enter the plurality of feeding channels of the color sorter, and the material quantity obtained by each channel of the color sorter is the same, and each channel of the color sorter is in the optimal identification state.

In some embodiments of the present invention, with reference to FIG. 3, the feed assembly 3 further includes a cover 34, the cover 34 being disposed on a side of the at least one feed channel 33 remote from the base plate 31, the cover 34 covering at least a portion of the feed channel 33. In some examples, the cover plate 34 may be disposed on a side of one of the distribution channels 33 far from the bottom plate 31, where the cover plate 34 covers at least a portion of one of the distribution channels 33, and the at least a portion of the distribution channel 33 may be understood as a portion of the distribution channel 33 or an entirety of the distribution channel 33, that is, where the cover plate 34 may cover a portion of a corresponding one of the distribution channels 33 or the cover plate 34 may cover an entirety of a corresponding one of the distribution channels 33.

In other examples thereof, the cover plate 34 may also be provided on a side of the plurality of distribution channels 33 remote from the base plate 31, in which case the cover plate 34 covers at least a portion of each distribution channel 33 of the plurality of distribution channels 33, i.e. in which case the cover plate 34 may cover a portion of each distribution channel 33 or the cover plate 34 may cover the entirety of each distribution channel 33.

Further, the cover plate 34 can cover the upper end portion of the material distribution channel 33, that is, the end of the material distribution channel 33 close to the housing 1, because the kinetic energy of the material after falling from the material inlet channel 10 is the largest, so that the material jumping is most likely to occur, and the cover plate 34 covers the upper end portion of the material distribution channel 33, so that the kinetic energy of the material of the seasoning can be absorbed, and the material jumping out of the material distribution channel 33 can be reduced.

In some embodiments of the utility model, as shown in FIG. 4, the cross-sectional area of the feed channel 33 gradually increases in a direction from the inlet end 331 to the outlet end 332 of the feed channel 33. Therefore, after the materials enter the material distributing channel 33 from the inlet end 331, the materials can be quickly evacuated in the material distributing channel 33 and leave the inlet end 331, and the material blockage at the inlet end 331 can be further reduced; moreover, the cross-sectional area of the material distributing channel 33 is gradually increased, so that the materials are gradually dispersed in the material distributing channel 33, and the materials can be in a better dispersed state when flowing out from the outlet end 332, which is beneficial to improving the material distributing effect of the material distributing component 3.

In some embodiments of the present invention, as shown in fig. 3 and 5, the feeding device 100 may further include a bracket 4, and the material-dividing assembly 3 is movably disposed on the bracket 4. The movable operation can be understood as that the material distributing assembly 3 moves on the support 4 in the up-down direction, and certainly, the material distributing assembly 3 moves on the support 4 in the horizontal direction, and the material flows out of the material distributing assembly 3 and then enters the subsequent processing equipment (such as a color sorter), so that the height of the feeding device 100 can be adjusted according to the size and height of the bin inlet of the subsequent processing equipment, the feeding device 100 is more matched with the subsequent processing equipment, and the material flowing out of the feeding device 100 can flow into the subsequent processing equipment as much as possible, and the waste of the material is reduced.
