[0027] The terms “first”, “second”, etc. are only used for distinguishing descriptions and should not be understood as indicating or implying relative importance.

For ordinary technicians in this field, the specific meanings of the above terms in this embodiment can be understood according to specific circumstances.

[0029] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0030] The feeder includes a belt conveyor, a silo, a lifting mechanism and an output mechanism which are sequentially connected along the conveying direction. The belt conveyor is used to convey materials into the silo, the silo is used to buffer materials, the lifting mechanism includes a lifting belt, which is used to output the materials in the silo and lift them to a set height, and the output mechanism is used to output the materials lifted by the lifting mechanism to the downstream production mechanism. However, the flow rate of the materials output by the lifting mechanism in the prior art is unstable.

[0031] The inventor has found through exploration that the main reason for the unstable flow rate of the material output by the lifting mechanism is that in the prior art, when the material falls from the output end of the belt conveyor into the silo 1, it accumulates in the middle of the silo 1. The running speed of the lifting mechanism is equal to the running speed of the belt conveyor, and the flow rate of the material transported by the belt conveyor into the silo 1 is fixed. If the material accumulates in the middle of the silo 1, the material transported by the lifting mechanism will fluctuate, making the flow rate of the material output by the lifting mechanism unstable.

[0032] The implementation mode of the utility model provides a silo, which can improve the uniformity of material distribution in the silo, thereby preventing the flow rate of the material output by the lifting mechanism from being unstable.

[0033] refer to Figure 1 The silo provided in this embodiment includes a silo body 1 and a guide plate 3. A feed port 2 is provided above the silo body 1, and the feed port 2 is located below the output end of the belt conveyor. The guide plate 3 is provided inside the silo body 1 and is arranged close to the feed port 2. The guide plate 3 can rotate relative to the silo body 1. The guide plate 3 is used to break up the material entering the feed port 2 so that the material in the silo body 1 is evenly distributed.

[0034] By adopting the above technical solution, by arranging the guide plate 3 near the feed port 2 of the silo, when the material enters the feed port 2, it collides with the guide plate 3, which can make the material loose and flow downward under the guidance of the guide plate 3. By setting the guide plate 3 to be able to reciprocate, the angle between the guide plate 3 and the vertical direction is constantly changing. When the material flows downward along the surface of the guide plate 3, it can reach all corners of the bottom of the silo, thereby avoiding the problem of excessive accumulation of materials in the silo in the prior art, and the resulting unstable output flow of the lifting mechanism.

[0035] Further, Figure 1 The structural view of the silo is shown, and mounting holes 5 are provided on two opposite side walls 4 of the silo body 1, and a hinge shaft 6 is provided on the guide plate 3. Both ends of the hinge shaft 6 are respectively inserted into the two mounting holes 5. The guide plate 3 can rotate around the axis of the hinge shaft 6, and the axis of the hinge shaft 6 is perpendicular to the feeding direction of the material. The guide plate 3 can continuously adjust the guiding direction of the material during the rotation process, so that the material is spread to all corners of the bottom of the silo, thereby improving the uniformity of material distribution in the silo.

[0036] Furthermore, if Figure 1 and Figure 2 As shown, arc-shaped through grooves 8 are provided on two opposite side walls 4, and the center of the arc-shaped through grooves 8 coincides with the center of the mounting hole 5; a slide bar 9 is provided on the guide plate 3, and the slide bar 9 passes through the arc-shaped through grooves 8. When the guide plate 3 rotates, the slide bar 9 can slide in the arc-shaped through grooves 8. The arc-shaped through grooves 8 can guide the guide plate 3 to rotate and prevent the guide plate 3 from deflecting.

[0037] Furthermore, if Figure 1 and Figure 2 As shown, a first bearing 10 is provided between the hinge shaft 6 and the mounting hole 5 to reduce the friction between the hinge shaft 6 and the mounting hole 5 and reduce wear.

[0038] Furthermore, if Figure 3 As shown, a sliding mechanism is provided in the arc-shaped through groove 8, and the sliding rod 9 is connected to the sliding mechanism. The sliding mechanism can slide back and forth along the arc-shaped through groove 8 to guide the sliding rod 9 of the guide plate 3 to rotate along an arc track.

[0039] Furthermore, if Figure 2 and Figure 3 As shown, the sliding mechanism includes a second bearing 11, which is arranged in the arc-shaped through groove 8, and the sliding rod 9 is inserted into the inner hole of the second bearing 11; an annular sliding groove 12 extending along its circumferential direction is provided on the outer circumferential surface of the second bearing 11, and the sliding groove 12 is clamped with the inner wall 7 of the arc-shaped through groove 8 to prevent the sliding rod 9 from being separated from the arc-shaped through groove 8.

[0040] Furthermore, the curvature of the arcuate slot 8 is 90-120 degrees. Specifically, the curvature can be set according to the particle size and fluidity of the material. For materials with smaller particle size and greater fluidity, the curvature of the arcuate slot 8 can be set to 90 degrees, and the angle between the line connecting the two ends of the arcuate slot 8 and the center of the positioning hole and the vertical direction is 45 degrees. For materials with larger particle size and lower fluidity, the curvature of the arcuate slot 8 can be set to 120 degrees, and the angle between the line connecting the two ends of the arcuate slot 8 and the center of the positioning hole and the vertical direction is 60 degrees.

[0041] Furthermore, the number of the guide plates 3 is two, and the two guide plates 3 are arranged along the width direction of the silo ( Figure 1 and Figure 2 The guide plates 3 and 3 are arranged at intervals (as shown in the X direction), and the width direction of the silo is perpendicular to the conveying direction of the belt conveyor. This is convenient for increasing the contact area between the guide plate 3 and the material, and further improving the uniformity of the material distribution in the silo.

[0042] Furthermore, a driving mechanism is also included, the driving mechanism is connected to the hinge shaft 6, and the driving mechanism is used to drive the hinge shaft 6 to reciprocate. Specifically, the driving mechanism includes a motor and a controller, and the controller is used to switch the rotation direction of the motor according to a set frequency to drive the guide plate 3 to reciprocate. The type of controller is not limited here, and all electrical appliances that can change the rotation direction of the motor are within the protection scope of this application.

[0043] An embodiment of the present application also provides a feeder, comprising any of the aforementioned silos.
