DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] In order to solve the problem of large drop height, it often takes a long time for powder to settle when distributing it. The technical problem of material accumulation is that the material is discharged too quickly, such as Figure 1-Figure 4 As shown, the following preferred technical solutions are provided:

[0031] An intelligent silo material distributing and unloading device comprises a silo body 1 and a feeding channel 2 overheadly arranged at the top of the silo body 1, the silo body 1 and the feeding channel 2 are connected through a chute 3, the material is transported to the top of the silo body 1 through the feeding channel 2, and then slides down into the silo body 1 through the chute 3, an annular partition 4 is fixedly connected to the upper end of the inner cavity side wall of the silo body 1, a driving component 5 is fixedly connected to the side wall of the annular partition 4 close to the inner circle, a first bracket 6 is fixedly connected to the bottom surface of the annular partition 4, a flow guide component 7 is rotatably connected through the first bracket 6, for guiding and conveying the material, one end of the driving component 5 is meshedly connected with one end of the flow guide component 7, a central shaft 8 is fixedly connected to the bottom surface of the flow guide component 7, a flattening component 9 and a discharging component 10 are fixedly connected to the upper end of the side wall of the central shaft 8, and the discharging component 10 After loading the material, it starts and unloads the material into the silo body 1. At the same time, the flattening component 9 flattens the unloaded material to make full use of the storage space. The inner cavity side wall of the silo body 1 is fixedly connected with a slide rail 20. One end of the flattening component 9 and the unloading component 10 are slidably set on the slide rail 20. The middle and lower part of the side wall of the central axis 8 is provided with an external thread 30. The side wall of the central axis 8 is threadedly connected with a support plate 40 through the external thread 30. The side wall of the support plate 40 is slidably connected to the inner cavity side wall of the silo body 1. When unloading, the support plate 40 plays a role in reducing the falling distance of the material, and gradually descends with the rotation of the central axis 8, thereby avoiding the problem that the material falls too far, recoils after falling, and takes a long time to settle after being lifted. The bottom end of the central axis 8 is rotatably connected to the second bracket 50, and the second bracket 50 is fixedly connected to the bottom wall of the inner cavity of the silo body 1.

[0032] During loading, the material is transported through the conveying channel 2 and enters the guide component 7 inside the silo body 1 via the chute 3. The discharge ports on both sides of the guide component 7 are periodically opened and closed. When the discharge port on one side is opened, the discharge port on the other side is closed, so that the material can be loaded at a certain rate to avoid the problem of material accumulation due to the low adhesion of the material being discharged too quickly under the action of gravity. During loading, the image recognition device installed on the bottom surface of the guide component 7 intelligently identifies the unloading component 10. When it is detected that the unloading component 10 on one side is in place, the controller controls the operation of the components in the guide component 7 to close one side and open the other side, and then reverse the opening to achieve the effect of alternating loading of the unloading components 10 on both sides.

[0033] When unloading, the unloading component 10 gradually turns downward along the spiral track. When there is more material in the unloading component 10, its inclination angle is small. As the material decreases, the inclination angle of the unloading component 10 gradually increases until it is completely turned over, and the material is evenly unloaded in the radial direction. At the same time, the central shaft 8 drives the flattening component 9 and the unloading component 10 to rotate, so that the unloading component 10 rotates along the circumferential direction when unloading, and then the flattening component 9 further distributes, combs and flattens the material, so that the storage space of the silo body 1 is fully utilized.

[0034] The driving assembly 5 includes two mounting plates 51 fixedly connected to the inner side wall of the annular partition 4, a first gear 52 is rotatably connected between the two mounting plates 51, and a driving motor 53 is fixedly connected to the top wall of the mounting plate 51 at the top.

[0035] The flow guide component 7 includes a material distribution barrel 71 rotatably connected to the first bracket 6, and a second gear 72 is fixedly connected to the outer wall of the material distribution barrel 71. The second gear 72 is meshingly connected to the first gear 52, so that under the meshing connection between the second gear 72 and the first gear 52, the driving motor 53 can drive the flow guide component 7 and the center shaft 8 to rotate.

[0036] A diverter plate 73 is rotatably connected to the inner wall of the dividing barrel 71, and the diverter plate 73 is controlled by a controller to turn. A stopper 74 is fixedly connected to the bottom wall of the inner cavity of the dividing barrel 71, and the inside of the dividing barrel 71 is divided into two areas by the stopper 74. The bottom wall of the inner cavity of the dividing barrel 71 on both sides of the stopper 74 is provided with a discharge channel 75, and a visual probe 76 is fixedly installed on the bottom surface of the dividing barrel 71 at the discharge channel 75. The unloading component 10 is inspected by the visual probe 76, thereby making the material distribution and unloading more intelligent.

[0037] Specifically, the chute 3 adopts a vibration unloading method so that the material can smoothly enter the guide component 7. The guide component 7 detects the unloading component 10 on the corresponding side through the visual probe 76 installed on the bottom surface. When the unloading component 10 reaches the loading position, the controller rotates the diverter plate 73 to a certain angle, so that the corresponding side of the dividing barrel 71 is opened, while the other side is blocked by the diverter plate 73, so that the material can enter the unloading channel 75 on one side, and finally loaded into the unloading component 10 in place. Since the unloading components 10 are alternately arranged during loading, when one side is loaded, the controller controls the diverter plate 73 to open the other side and load the unloading component 10 on the other side, and so on, thereby achieving the effect of continuous and uniform unloading. Compared with the traditional direct unloading method, the unloading speed can be controlled more accurately and effectively to avoid the problem of excessive accumulation of materials due to excessive unloading.

[0038] In order to solve the technical problem of uniform material distribution through rotary flattening, the flattening only involves the rotation of the flattening plate, which results in greater resistance when the material is thick, leading to increased power consumption. Figure 5-Figure 7 As shown, the following preferred technical solutions are provided:

[0039] The flattening assembly 9 includes a fixed sleeve 91, on the inner wall of which a plurality of connecting keys 92 are fixedly arranged, and on the side wall of the fixed sleeve 91 a first cross frame 93 is symmetrically fixedly connected, and a pulley 94 is fixedly installed at one end of the first cross frame 93 away from the fixed sleeve 91, and the pulley 94 is slidably arranged on the slide rail 20 to play a guiding and supporting role, and a connecting seat 95 is fixedly connected to the bottom surface of each first cross frame 93, and on the bottom wall of the connecting seat 95 a plurality of comb teeth 96 are fixedly installed, and the material is combed and dispersed by the comb teeth 96.

[0040] A plurality of key slots 81 matching the connecting keys 92 are formed on the outer wall of the central shaft 8 , so that the flattening assembly 9 can be driven to rotate by the central shaft 8 .

[0041] The side walls of the two comb teeth 96 located on the outside are fixedly connected with inclined rods 97 , and the side walls of the two inclined rods 97 are rotatably connected with roller shafts 98 , which are arranged behind the comb teeth 96 .

[0042] Specifically, when the center shaft 8 rotates, the connection between the connecting key 92 and the keyway 81 drives the flattening assembly 9 to rotate in the same direction at a low speed. The pulley 94 at one end of the first cross frame 93 slides on the annular slide rail 20, guiding and supporting the flattening assembly 9, making it more stable during operation. At the same time, the comb teeth 96 on the bottom surface of the flattening assembly 9 rotate to comb and disperse the radially distributed materials, and the rear roller 98 further flattens the materials immediately after the comb teeth 96, so that the materials can be evenly distributed and the storage space can be fully utilized. At the same time, since the upper plate 40 is threadedly connected to the center shaft 8 by the external thread 30, the outer ring side wall of the support plate 40 is slidably connected to the inner wall of the silo body 1, and it slowly descends when the center shaft 8 rotates, thereby reducing the height of the falling material and enabling the flattening assembly 9 to always flatten the material at the top.

[0043] In order to solve the technical problem that materials accumulate in the outermost circle, resulting in local accumulation, the storage space cannot be fully utilized, and the utilization rate of the silo is reduced, such as Figure 5 , Figure 8 and Fig. 9 As shown, the following preferred technical solutions are provided:

[0044] The unloading assembly 10 includes two second cross frames 101 which are sleeved on the outer wall of the fixed sleeve 91. The two second cross frames 101 are symmetrically arranged and are arranged at right angles to the first cross frame 93. The two second cross frames 101 are fixedly connected to the two first cross frames 93 respectively. A semi-cylinder 102 is symmetrically fixedly connected to the side wall of each second cross frame 101. A slider 103 is fixedly connected to the end of the two semi-cylinders 102 away from the fixed sleeve 91. The slider 103 is slidably connected to the slide rail 20.

[0045] A guide rail 104 is fixedly connected to the outer wall of each semi-cylinder 102, and the guide rail 104 is arranged in a spiral shape. A discharge vehicle 105 is slidably connected to each guide rail 104, and one end of each discharge vehicle 105 close to the outer side of the second horizontal frame 101 is a slope structure to facilitate discharge.

[0046] The unloading vehicle 105 includes a hopper 1051, on the bottom surface of which a moving block 1052 is fixedly installed. The moving block 1052 is driven by electricity and can move back and forth along the guide rail 104. A gravity sensor 1053 is fixedly installed on the bottom surface of the inner cavity of the hopper 1051. The gravity sensor 1053 is a columnar structure. The measuring end of the gravity sensor 1053 is fixedly connected to a pressure plate 1054. By detecting the pressure of the pressure plate 1054, the weight of the loaded material can be weighed.

[0047] Specifically, when the unloading trolley 105 in the unloading assembly 10 is loading, the gravity sensor 1053 can measure the weight of the loaded material by detecting the pressure of the pressure plate 1054. When the set loading weight is reached, the unloading trolley 105 is started by the controller, and the unloading trolley 105 moves along the spirally arranged guide rail 104 and gradually tilts to the side. The material loaded by the unloading trolley 105 falls onto the support plate 40 inside the silo body 1 through the inclined surface. As the unloading trolley 105 moves on the guide rail 104, the material is gradually unloaded. The inclination angle also gradually increases, which makes it easier to unload the material at the bottom. When it finally reaches the end of the guide rail 104, the unloading cart 105 is completely turned over and stops. When the unloading cart 105 on the other side is loaded with material and starts, the unloaded unloading cart 105 at the end of the guide rail 104 moves in the opposite direction along the guide rail 104 to reset, and so on. Intelligent alternating loading and unloading is achieved, and the spiral guide rail 104 is set to make the material evenly distributed in the radial direction, avoiding the problem of excessive accumulation of material during unloading, resulting in greater resistance of the flattening component 9 and increased energy consumption.
