[0036] At present, at the tailings stage of the storage cabinet discharge, the flow rate fluctuates due to the thin thickness of the material. In order to ensure the stability of the flow rate, it is necessary to manually enter the storage cabinet to push the tailings into the discharge port. The manual cleaning method of the tailings is not only labor-intensive and inefficient, but also has certain safety hazards.

[0037] In order to solve the above technical problems, the utility model provides a material unloading device, which can automatically clean up the tailings in the storage cabinet, thereby saving manpower and improving the cleaning efficiency.

[0038] In order to make the technical solution and advantages of the present invention more clear, the implementation methods of the present invention are described in further detail below.

[0039] refer to Figures 1 to 3The embodiment of the utility model provides a feeding device, which is arranged at the output end of the storage cabinet 6, and the storage cabinet 6 is provided with a first direction (such as Figure 1 The conveyor bottom belt 7 extends in the vertical direction (as shown in the X direction in FIG. 1 ), and the conveyor bottom belt 7 is used to convey materials. The unloading device includes a mounting frame 1, a scissor mechanism 2, a push plate 3 and a moving mechanism 4. The mounting frame 1 is arranged above the output end of the storage cabinet 6. The scissor mechanism 2 is arranged on the mounting frame 1, and the scissor mechanism 2 can move in the vertical direction (as shown in the X direction in FIG. 1 ). Figure 3 The push plate 3 is arranged at the bottom of the scissor mechanism 2, and the push plate 3 can move between the first position and the second position in the vertical direction under the drive of the scissor mechanism 2. When the push plate 3 moves downward to the first position, the bottom of the push plate 3 can contact the upper surface of the conveyor bottom belt 7. When the push plate 3 moves upward to the second position, the bottom of the push plate 3 is separated from the upper surface of the conveyor bottom belt 7. The push plate 3 is used to discharge the materials at the output end of the storage cabinet 6. The moving mechanism 4 is arranged on the mounting frame 1 and connected to the scissor mechanism 2. The moving mechanism 4 can drive the scissor mechanism 2 to move in the first direction, so as to drive the push plate 3 to move in the first direction.

[0040] When it is necessary to clean the tailings of the storage cabinet 6, the moving mechanism 4 first drives the scissor mechanism 2 to move along the first direction to drive the push plate 3 to move to the side of the tailings away from the discharge port 61, and then the scissor mechanism 2 extends in the vertical direction to drive the push plate 3 to move downward to the first position, so that the bottom of the push plate 3 contacts the upper surface of the conveyor bottom belt 7, and the moving mechanism 4 drives the scissor mechanism 2 to move along the first direction to move the push plate 3 toward the discharge port 61 to push the tailings out of the discharge port 61, that is, to complete the cleaning of the tailings of the storage cabinet 6. The utility model can automatically and quickly clean the tailings of the storage cabinet 6, saving manpower and improving the cleaning efficiency.

[0041] Optionally, refer to Figure 1 There is an angle between the extension direction of the push plate 3 and the vertical direction. For example, the angle between the extension direction of the push plate 3 and the vertical direction can be 70-80 degrees. The horizontal spacing between the push plate 3 and the output end gradually decreases from top to bottom. By tilting the push plate 3, the design can reduce the resistance of the push plate 3 when pushing the material, thereby facilitating the pushing of the tail material.

[0042] Optionally, refer to Figure 3 The mounting frame 1 is provided with a Figure 3The first slide rail 11 extends in the Y direction (as shown in the Y direction in the figure), and the second direction is the width direction of the conveyor bottom belt 7. The first slide rail 11 is provided with a first slider (not shown in the figure), and the first slider can slide along the first slide rail 11. The scissors mechanism 2 includes at least one set of scissors assemblies, a base 21 and a driving mechanism 24. The scissors assembly includes two cross-arranged first scissors rods 22 and second scissors rods 23, and the middle parts of the first scissors rods 22 and the second scissors rods 23 are hinged. When the number of scissors assemblies is multiple, the number of scissors assemblies is an odd number, and each scissors assembly is arranged in sequence along the vertical direction. In two adjacent scissors assemblies, the bottom ends of the first scissors rods 22 and the second scissors rods 23 in the upper scissors assembly are respectively hinged to the top ends of the second scissors rods 23 and the first scissors rods 22 in the lower scissors assembly. The base 21 is located below the bottom scissor assembly, and the upper surface of the base 21 is provided with a second slide rail 211 extending along the second direction, and the second slide rail 211 is provided with a second slider (not shown in the figure), and the second slider can slide along the second slide rail 211. The top end of the first scissor rod 22 in the top scissor assembly is hinged to the first slider, and the top end of the second scissor rod 23 is hinged to the mounting frame 1. The bottom end of the second scissor rod 23 in the bottom scissor assembly is hinged to the second slider, and the bottom end of the first scissor rod 22 is hinged to the base. The driving mechanism 24 is used to drive the base 21 to move in the vertical direction, so as to drive the scissor mechanism 2 to extend and retract in the vertical direction.

[0043] Specifically, refer to Figure 3 The driving mechanism 24 includes a motor 241, a rotating shaft 242 and two pulleys 243. The motor 241 is arranged on the mounting frame 1. The rotating shaft 242 is arranged on the mounting frame 1, and the rotating shaft 242 extends along the second direction. The rotating shaft 242 is connected to the motor 241 and can rotate around its own axis under the drive of the motor 241. The two pulleys 243 are respectively arranged at the two ends of the rotating shaft 242. The axis of the pulley 243 coincides with the axis of the rotating shaft 242. The pulley 243 can rotate around its own axis under the drive of the rotating shaft 242. A belt 25 is wound around the pulley 243. The belt 25 includes a free end and a connecting end. The connecting end is fixedly connected to the base 21, and the free end is fixedly connected to the pulley 243. When the pulley 243 rotates, the belt 25 can be lengthened or shortened, thereby driving the base 21 to move up and down in the vertical direction (in this embodiment, the "upper" position is as shown in FIG. 1 ). Figure 3 As shown in the C direction in the figure, the "down" direction is as follows Figure 3 The scissor mechanism 2 is simultaneously driven to extend and retract in the vertical direction.

[0044] When the tailings in the storage cabinet 6 need to be cleaned, the motor 241 drives the rotating shaft 242 and the pulley 243 to rotate, thereby lengthening the belt 25 so that the base 21 moves downward in the vertical direction. At this time, the top end of the first scissor rod 22 in the uppermost scissor assembly and the bottom end of the second scissor rod 23 in the lowermost scissor assembly move toward the middle of the storage cabinet 6 respectively, that is, both move along Figure 3 The scissor mechanism 2 moves in the direction A in the figure to reduce the angle between the first scissor rod 22 and the second scissor rod 23 in each group of scissor assembly and the vertical direction, so that the scissor mechanism can be extended in the vertical direction. When the bottom of the push plate 3 contacts the upper surface of the conveyor bottom belt 7, the motor 241 stops running, and then the moving mechanism 4 drives the scissor mechanism 2 to move in the first direction toward the discharge port 61 to push the tailings out of the discharge port 61, that is, to complete the cleaning of the tailings in the storage cabinet 6.

[0045] After the cleaning of the tailings in the storage cabinet 6 is completed, the motor 241 drives the rotating shaft 242 and the pulley 243 to rotate in the opposite direction, thereby shortening the belt 25, so that the base 21 moves upward in the vertical direction. At this time, the top end of the first scissor rod 22 in the uppermost scissor assembly and the bottom end of the second scissor rod 23 in the lowermost scissor assembly move toward the two sides of the storage cabinet 6 respectively, that is, both move along Figure 3 The first scissor rod 22 and the second scissor rod 23 in each group of scissor assembly move in the direction B to increase the angle between the first scissor rod 22 and the second scissor rod 23 and the vertical direction, so that the scissor mechanism contracts in the vertical direction. When the bottom of the push plate 3 is separated from the upper surface of the conveyor bottom belt 7 and the push plate 3 moves to a preset height, the motor 241 stops running, and then the moving mechanism 4 drives the scissor mechanism 2 to move in the first direction away from the discharge port 61 to wait for the next cleaning of tailings.

[0046] Optionally, the thickness of the push plate 3 is 2-3 mm.

[0047] Optionally, the push plate 3 is made of stainless steel, which has good corrosion resistance and can increase the service life of the push plate 3.

[0048] Optionally, refer to Figure 1 , further comprising two pads 5, which are sequentially arranged on both sides of the push plate 3 along the second direction. When the push plate 3 is located at the first position, the two pads 5 are respectively in contact with the two inner side walls of the storage cabinet 6. The utility model can avoid the push plate 3 from directly contacting the inner wall of the storage cabinet 6 by designing the pads 5, thereby avoiding friction on the push plate 3 and improving the service life of the push plate 3.

[0049] Optionally, the pad 5 is made of a silicone material. The silicone material has good elasticity and is not easily deformed after long-term use, which can increase the service life of the pad 5 and prevent the material from leaking from the gap between the push plate 3 and the inner side wall of the storage cabinet 6 when pushing the material.
