DETAILED DESCRIPTION

The present invention will be further described below in conjunction with the embodiments.

Please refer to Figures 1-4. The utility model provides an automatic conveying mechanism for solid chemical raw materials, including a frame 1, the inner wall of the frame 1 is rotatably connected to two parallel conveying rollers 2, the outer surfaces of the two conveying rollers 2 are sleeved with conveyor belts 3, the outer end of the frame 1 is provided with a conveying motor 4 coaxially connected to the bottom conveying rollers 2, and also includes a blocking block 5, the blocking block 5 is in contact with the bottom top surface of the conveyor belt 3 and is fixed to the inner wall of the frame 1, a distributing barrel 6 is fixed to the top surface of the distributing barrel 6, the inner wall of the distributing barrel 6 is rotatably connected to a rotating blade 7, the outer ends of the rotating blade 7 and the outer ends of the conveying rollers 2 at the bottom are respectively coaxially fixed with rotating gears 8, the two rotating gears 8 are meshed and connected, the top inner wall of the distributing barrel 6 is slidably connected to a feed hopper 9, and the outer side of the feed hopper 9 is provided with a buffer feeding mechanism 10;

There are two material blocking bars 11, which are respectively fixed to the top surface of the frame 1, and a material blocking cover 12 is fixed to the top surface of the two material blocking bars 11, and a material dividing groove 13 opened on the surface of the material dividing barrel 6 is arranged below the material blocking cover 12, and a reflux groove 14 opened on the outer surface of the bottom of the material dividing barrel 6 is arranged below the material dividing groove 13, and a discharge plate 15 rotatably connected to the inner wall of the frame 1 is arranged on the top bottom surface of the conveyor belt 3, and a buffering blanking mechanism 16 matched with the discharge plate 15 is arranged on the inner wall of the frame 1.

As further shown in FIGS. 1 , 2 and 4 , it is worth specifically explaining that the buffer feeding mechanism 10 includes a guide sleeve 101, which is provided with four guide sleeves 101 and is fixed to the top two side walls of the distributing barrel 6 in a rectangular distribution, and an L-shaped rod 102 fixed to the side wall of the feed hopper 9 is provided above each guide sleeve 101, and a limiting rod 103 fixed to the bottom surface of the L-shaped rod 102 is provided on the inner wall of the guide sleeve 101, and a supporting spring 104 fixed to the opposite surface of the L-shaped rod 102 and the guide sleeve 101 is provided on the outer surface of the limiting rod 103;

The diverter block 105 is arranged inside the feed hopper 9 , and connecting rods 106 are fixed between the bottom surface of the diverter block 105 and the inner walls of both end surfaces of the diverter barrel 6 .

As further shown in Figure 3, it is worth explaining in detail that the bottom end face of the feed hopper 9 is provided with a slide groove 17 adapted to the connecting rod 106, and the vertical cross-section of the diverter block 105 is arranged in an isosceles triangle. The setting of the slide groove 17 enables relative movement between it and the connecting rod 106, and cooperates with the limiting effect of the distribution barrel 6 on the feed hopper 9, thereby ensuring that the solid chemical raw materials can be adaptively adjusted and processed when entering the distribution barrel 6.

As further shown in FIGS. 1 , 2 , 3 and 4 , it is worth specifically explaining that the buffering blanking mechanism 16 comprises an L-shaped plate 161, which is slidably arranged on the inner wall of the frame 1, and two symmetrically distributed vertical rods 162 are arranged through the inner wall of the L-shaped plate 161, and the bottom ends of the two vertical rods 162 are fixed to the frame 1, and the outer surface of the vertical rod 162 is provided with a buffer spring 163 fixed to the opposite surface of the L-shaped plate 161 and the frame 1;

There are two rotating rods 164 and they are rotatably connected to the outer surface of the L-shaped plate 161 respectively. Two symmetrically distributed limiting rings 165 are fixed to the bottom surface of the discharge plate 15. The top end of the rotating rod 164 is sleeved inside the limiting ring 165.

This scheme has the following working process: when the solid chemical raw materials are automatically conveyed and processed, the solid chemical raw materials enter from the feed hopper 9 through the discharge pipe of the storage silo, and enter the rotating blade 7 in the distribution barrel 6 through the diversion of the diversion block 105. At this time, the two conveying rollers 2 drive the conveyor belt 3 to continuously convey from bottom to top in a clockwise direction through the driving of the conveying motor 4, and the rotating blade 7 rotates counterclockwise in the distribution barrel 6 through the meshing transmission between the two rotating gears 8, so that the solid chemical raw materials are driven to fall from the distribution trough 13 to the Above the conveyor belt 3, the solid chemical raw materials are automatically transported to the discharge plate 15 for unloading. A small amount of solid chemical raw materials fall above the conveyor belt 3 and enter the distributing barrel 6 through the reflux groove 14, so that they are rotated and transported to the top of the conveyor belt by the rotating blade 7 until they reach the discharge plate 15. When the solid chemical raw materials reach the discharge plate 15, the limit ring 165, the rotating rod 164 and the L-shaped plate 161 are set, so that the discharge plate 15 can be rotated slightly with the gravity of the solid chemical raw materials, thereby realizing the unloading of the solid chemical raw materials by the discharge plate 15;

When the flow rate of the solid chemical raw material conveying in the silo is large or in a stacking state, a certain gravity pressure is formed on the top of the feed hopper 9. At this time, the support spring 104 is compressed by the L-shaped rod 102 and the limit rod 103, so that the feed hopper 9 moves downward in the distributor barrel 6 through its side wall and the slide groove 17, thereby increasing the distance between the top inner wall slope of the feed hopper 9 and the diverter block 105, forming a buffer feeding treatment for the solid chemical raw materials.

According to the above working process, it can be known that: through the setting of the buffer feeding mechanism 10, the input amount of the solid chemical raw material is adaptively adjusted, and the solid chemical raw material is blocked by the separation cylinder and the blocking block 5 to effectively prevent the solid chemical raw material from spilling. At the same time, through the setting of the blocking strip 11 and the blocking cover 12, the dust caused by the height difference during the feeding of the solid raw material is effectively prevented from escaping to the external environment. Through the setting of the rotating blade 7, the dividing trough 13 and the reflux trough 14, the solid chemical raw material is fully rotated and sent to the top of the conveyor belt 3 and fully transported to the unloading plate 15 for unloading processing. Through the setting of the buffer dropping mechanism 16, the unloading plate 15 is rotated slightly on the frame 1, so that the solid chemical raw material is buffered and protected to a certain extent when entering the subsequent processing equipment, effectively avoiding local impact.

As further shown in Figures 1, 3 and 4, it is worth specifically explaining that the side walls at both ends of the unloading plate 15 are in contact with the opposite surfaces of the two blocking strips 11 respectively, the top surface of the unloading plate 15 is inclined with respect to the frame 1, and the blocking strips 11 are in contact with the unloading plate 15 to prevent the solid chemical raw materials from spilling when being transported to the unloading plate 15. The unloading plate 15 is inclined to provide a certain degree of buffering for the solid chemical raw materials to prevent the solid chemical raw materials from directly impacting subsequent processing equipment.

As further shown in Figures 3 and 4, it is worth specifically explaining that the end of the rotating blade 7 is provided with a protrusion extending inward, and the bottom surface of the blocking block 5 is provided with an inclined chamfer. The shape of the rotating blade 7 allows the solid chemical raw materials entering the distribution barrel 6 to form a certain accumulation at each blade of the rotating blade 7, thereby facilitating the rotation of the rotating blade 7. The solid chemical raw materials can better enter the upper part of the conveyor belt 3 from the distribution trough 13 for automatic transportation and processing. The inclined chamfer at the bottom of the blocking block 5 forms a certain degree of scraping on the top surface of the conveyor belt 3 to prevent the solid chemical raw materials from remaining on the surface of the conveyor belt 3.

In summary: through the setting of the buffer feeding mechanism 10, the input amount of the solid chemical raw material is adaptively adjusted, the solid chemical raw material is blocked by the separation cylinder and the blocking block 5, and at the same time, the setting of the blocking bar 11 and the blocking cover 12 can effectively prevent the solid raw material from escaping to the external environment due to the height difference during feeding. Through the setting of the rotating blade 7, the dividing trough 13 and the reflux trough 14, the solid chemical raw material is fully rotated and sent to the top of the conveyor belt 3 and fully transported to the unloading plate 15 for unloading processing. Through the setting of the buffer dropping mechanism 16, the solid chemical raw material is buffered and protected to a certain extent when entering the subsequent processing equipment, effectively avoiding local impact.

The conveying motor 4 can be purchased from the market and equipped with a power supply, which is a mature technology in this field and has been fully disclosed, so it will not be repeated in the specification.
