[0036] See also Figure 1 This embodiment provides a material silo device 100, including a silo 10, wherein a discharge port 11 is provided at the bottom of the silo 10 for discharging the material in the silo 10. The silo 10 can be provided in an inclined bucket shape, gradually shrinking from the upper entrance to the lower exit. The discharge port 11 is provided at the bottom exit position of the silo 10, and can be provided at the center of the bottom of the silo 10 as required. Figure 1 As shown, the bottom of the silo 10 can also be set to an inverted V-shaped fork to divide the bottom outlet of the silo 10, which can reduce the possibility of overall bridging of materials at the outlet. In a further embodiment, the outlet of the silo 10 can be divided into more parts, and a vertical rib partition plate structure can be set in each unit outlet to achieve the purpose of cutting off the bridging of materials. Of course, in the actual equipment setting, the segmentation setting of the silo 10 outlet cannot be infinitely small, otherwise it may cause congestion of the material itself.

[0037] See also Figure 1 and Figure 2The material silo device 100 further includes at least one unloading mechanism 20, which is disposed at the bottom outlet of the silo 10 and connected to the frame of the silo 10. The unloading mechanism 20 disposed at the bottom of the silo 10 can push the material in the silo space 101 of the silo 10. Preferably, a pushing unit 22 is disposed in the unloading mechanism 20, specifically but not limited to at least one pushing plate 221, which is controlled to push the material from one side to the other side into the material outlet on the other side.

[0038] In a more preferred embodiment, the pushing unit 22 can also be set from both sides, so as to push the material to the central downstream outlet at the same time. In a further preferred embodiment of the present invention, the pushing unit 22 is set to adopt a multi-layer structure, for example, three layers of pushing plates are set in steps, and the material is pushed into the central outlet discharge port 11 in a progressive manner in sequence, so that the particularly viscous material can also be pushed out to the central discharge port 11 in sequence, thereby ensuring that the material will not form a bridge during the discharge process, and the setting of the discharge mechanism 20 can continuously push the material in the silo space 101 to the discharge port 11, so that the viscous non-flowing material is forced to be pushed out of the silo 10, thereby achieving the purpose of preventing the material from bridging and blocking in the silo space 101, and ensuring that the discharge process of the viscous non-flowing material can proceed smoothly.

[0039] In a preferred embodiment of the present invention, please refer to Figure 3 The discharge mechanism 20 is also provided with a support unit 21, which is provided as at least one support plate 211 structure in the frame 24 of the discharge mechanism 20, so that it can be used to support materials and support the frame strength of the discharge mechanism 20. In a preferred embodiment, the support unit 21 can be provided to form a step shape matching the push unit 22, and the push plate 221 structure of the push unit 22 can be directly reciprocated in the gap between the support plate 211 structure of the support unit 21, so that when the push unit 22 pushes the viscous material toward the discharge port 11, it is possible that the material is adhered to the front of the push unit 22 (the back is close to the support plate 211 of the next layer, and there will be less adhered material). When it withdraws, the material can be retained in front of the push unit 22 through the scraping action of the upper support plate 211, waiting for the next push of the push unit 22, and the material is further pushed to the next layer or finally pushed into the discharge port 11.

[0040] The unloading mechanism 20 of the present invention can make full use of the bottom space of the silo space 101 of the silo 10, so that the silo space 101 has a larger bottom area, so as to increase the efficiency of pushing materials. In a more preferred embodiment, the pushing unit 22 and the support unit 21 and its frame 24 can form a unit module that is easy to disassemble and assemble, and according to the bottom area of ​​different silo spaces 101, multiple unloading mechanisms 20 can be arranged for splicing to maximize the efficiency of unloading.

[0041] In a preferred embodiment of the present invention, the pushing unit 22 can reciprocate relative to the discharge port 11 to push the material to the discharge port 11 to enter a subsequent processing procedure, such as drying or other processing procedures. Specifically, the pushing unit 22 is arranged in cooperation with the support unit 21, and the pushing unit 22 can move relative to the support unit 21 to push the material to the discharge port 11 to prevent it from forming a bridging phenomenon.

[0042] In an embodiment of the silo device of the present invention, the unloading mechanism 20 is further provided with a pushing member 23, and the pushing member 23 is arranged on the outer side of the pushing unit 22 away from the unloading port 11. The pushing member 23 is connected to the pushing unit 22 and drives the pushing unit 22 to reciprocate relative to the supporting unit 21.

[0043] During specific use, the pushing member 23 provides thrust for the pushing unit 22, so that the pushing unit 22 reciprocates relative to the supporting unit 21 at a certain speed, so as to continuously push the material supported on the supporting unit 21 to the discharge port 11, so that the viscous non-flowing material is forced out of the silo 10, preventing the material from bridging and sticking in the silo space 101.

[0044] In a preferred embodiment, see Figure 3 and Figure 4 The support unit 21 includes at least one support plate 211; the pusher unit 22 includes at least one pusher plate 221, which is arranged between the support plates 211 and can be set to a length corresponding to the support plate 211 on the upper layer. Each pusher plate 221 of the pusher unit 22 is also correspondingly provided with a push rod 222, and the pusher 23 is connected to drive the pusher plate 221 through the push rod 222, so as to realize the reciprocating motion of the pusher plate 221. The pusher 23 can be specifically but not limited to a controlled driving device such as an electric motor or a pneumatic or hydraulic cylinder.

[0045] During specific use, the pushing member 23 provides thrust to the pushing rod 222, and the pushing rod 222 pushes the pushing plate 221, so that the pushing plate 221 located between the support plates 211 of different step widths can reciprocate, so as to push the material supported on the support plate 211 (actually the material falling from the silo) to the discharge port 11, so as to smoothly discharge the material in the silo space 101 from the discharge port 11 without the problem of material bridging and blockage. The discharge mechanism 20 has a simple structure and is easy to operate.

[0046] See also Figure 3 The support unit 21 includes a plurality of support plates 211, and the plurality of support plates 211 are arranged in a stepped manner. Figure 5 A first gap 212 is provided between adjacent support plates 211 to accommodate the pusher plates 221. The plurality of pusher plates 221 may be arranged in a stepped manner. Figure 6 A second gap 223 is provided between adjacent push plates 221 .

[0047] The push plate 221 is inserted into the first gap 212 , the support plate 211 is inserted into the second gap 223 , and the push plate 221 is in contact with the support plate 211 .

[0048] By setting a first gap 212 between adjacent support plates 211, setting a second gap 223 between adjacent push plates 221, the push plate 221 is inserted into the first gap 212, and the support plate 211 is inserted into the second gap 223, and the support plate 211 and the push plate 221 are in contact and connected, it can be ensured that the material in the silo space 101 will not leak out from between the push plate 221 and the support plate 211. Under the action of the pusher 23, the push plate 221 can move relative to the support plate 211, and the support unit 21 in this embodiment includes a plurality of support plates 211, and the push unit 22 also includes a plurality of push plates 221, which facilitates quantitatively and continuously pushing the material in the silo space 101 with a large bottom area to the discharge port 11.

[0049] In a specific embodiment, the support unit 21 includes four support plates 211 with three first gaps 212, and the pusher unit 22 includes three pusher plates 221 with two second gaps 223. The three pusher plates 221 are sequentially inserted into the first gaps 212, and the support plates 211 located in the middle two layers are respectively inserted into the two second gaps 223, and the top support plate 211 is located on one side of the top pusher plate 221, and the bottom support plate 211 is located on one side of the bottom pusher plate 221. It should be understood that the number of support plates 211 included in the support unit 21 and the number of pusher plates 221 included in the pusher unit 22 are not limited to the above-mentioned situations, and they can be set according to actual conditions, and are not limited here.

[0050] In one embodiment, see Figure 6 The pusher unit 22 further includes a plurality of push rods 222, and the lengths between the plurality of push rods 222 are arranged in a step-like manner, so that the plurality of pusher plates 221 are arranged in a step-like manner. By arranging a plurality of pusher rods 222 arranged in a step-like manner on one side of the plurality of pusher plates 221, it is convenient to arrange the plurality of pusher plates 221 in a step-like manner. The arrangement of the pusher rods 222 facilitates the pusher 23 to provide thrust for the pusher plates 221, and the entire pusher unit 22 has a simple structure.

[0051] See also Figure 7 At least baffles are provided on both sides of the plurality of support plates 211, and the plurality of support plates 211 are arranged in a stepped manner between the baffles on both sides and connected to the baffles. Two or more baffles form the frame 24. The setting of the baffles not only facilitates the formation of the sealed silo space 101, but also facilitates the arrangement of the plurality of support plates 211 in a stepped manner.

[0052] See also Figure 8 An inverted V-shaped shield 12 is also provided at the lower part of the silo space 101, and the shield 12 is connected to the inner wall of the silo 10, and the shield 12 is located above the discharge port 11. The outer dimensions of the shield 12 are larger than the diameter of the discharge port 11 so as to cover the discharge port 11, so as to avoid the material bridging phenomenon caused by the material in the silo space 101 falling directly into the discharge port 11 from directly above the discharge port 11, and a discharge gap 13 for material discharge is reserved between the shield 12 and the support unit 21, so as to facilitate the pushing unit 22 to push the material supported on the support unit 21 out from the discharge gap 13 to the discharge port 11, thereby completing the material discharge.

[0053] Please continue reading Figure 8The mask 12 includes a first baffle 121, which is tilted and connected to the inner wall of the silo 10; the mask 12 also includes a second baffle 122, which is tilted and connected to the inner wall of the silo 10, and the first baffle 121 and the second baffle 122 form an inverted V shape.

[0054] The closed tip of the inverted V-shape is arranged toward the side away from the discharge port 11, which can achieve that the material does not get blocked by gravity bridge breaking during the discharge process, thus better avoiding the occurrence of material bridging. The open end of the inverted V-shape is arranged toward the discharge port 11, and the size of the open end is larger than the diameter of the discharge port 11, so as to prevent the material located directly above the discharge port 11 from falling directly into the discharge port 11.

[0055] Please continue reading Figure 8 The cover 12 divides the lower part of the silo space 101 into a first unloading area 1011 and a second unloading area 1012. At least one unloading mechanism 20 is provided in the first unloading area 1011, and at least one unloading mechanism 20 is provided in the second unloading area 1012. At least one unloading mechanism 20 is provided in each unloading area, so that the unloading port 11 can receive materials pushed out from opposite directions. In actual operation, the unloading mechanism 20 in the first unloading area 1011 and the unloading mechanism 20 in the second unloading area 1012 can be operated alternately, which can improve the efficiency of unloading and is not easy to be blocked.
