In this embodiment: this novel belt sampling device mainly falls into three parts: a conveying mechanism 1, a sampling mechanism 2 and a valve mechanism 3. In use, the apparatus first places the ore feed material on a conveyor belt 101 and conveys it clockwise by means of conveyor rollers 102. When the ore is required to be sampled, the conveying arc plate 309 is rotated downwards, and when the conveying arc plate 309 rotates to the lower part of the feed inlet 213 from the side, the rotating ring 306 drives the rotating plate 304 to rotate and open the feed inlet 213 through the swinging arm 308. Since the feed port 213 is of a downward inclined design, when the conveying arc 309 is rotated downward below the feed port 213, the conveying arc 309 is also inclined. Mineral powder on the conveyor belt 101 is flushed by inertia through the conveying arc 309 into the first feed cylinder 211 and the second feed cylinder 212. Then, the motor 202 is started, and the motor 202 drives the first conveying fan 221 and the second conveying fan 222 on two sides to rotate through the driving gear 203 and the linkage gear 204. Wherein the inner sample can be sampled by the first feed cylinder 211, the outer sample can be sampled by the second feed cylinder 212, and the sampled raw materials are collected by the respective discharge pipes 224 and fall into the collection tank 225. When the motor 202 drives the linkage gear 204 to rotate, the vibration plate 218 can circularly knock the vibration block 214, so that the sample is prevented from adhering to the inner wall to affect the subsequent sampling operation.
Referring to fig. 5-6, a first conveying fan 221 is rotatably disposed in the first conveying cylinder 211, a second conveying fan 222 is rotatably disposed in the second conveying cylinder 212, a through hole 223 matching with the first conveying fan 221 is formed on a side surface of the first conveying cylinder 211, and a through hole 223 matching with the second conveying fan 222 is also formed on a side surface of the second conveying cylinder 212.
In this embodiment: since the side surface of the first feed cylinder 211 does not contact the first driven gear 205, a through hole 223 is formed in the side surface of the first feed cylinder 211 to be engaged with the first feed fan 221. The side surface of the second feed cylinder 212 is not in contact with the driven gear two 206, and therefore a through hole 223 is formed in the side surface of the second feed cylinder 212 to be engaged with the second feed fan 222.

The beating structure 207 comprises a plurality of groups of connecting arms 215, the tail ends of the connecting arms 215 are connected with transverse plates 216, symmetrical screw rods 217 are movably arranged on the transverse plates 216, vibration plates 218 are fixedly connected to the outer sides of the screw rods 217, vibration damping springs 219 are further arranged between the transverse plates 216 and the vibration plates 218, the vibration damping springs 219 are sleeved on the screw rods 217, adjusting nuts 220 are further connected to the screw rods 217 in a threaded mode, and the adjusting nuts 220 are in butt joint with the inner sides of the transverse plates 216.
In this embodiment: in order to further improve the sampling and conveying effect, the ore sample is prevented from adhering to the inner wall after long-term use, so a beating structure 207 is provided on the inner side of the linkage gear 204. As the motor 202 rotates the linkage gear 204, the vibration plate 218 may cyclically strike the vibration block 214. In order to further improve the degree of freedom of the device and to adaptively adjust the vibration force according to the requirement, an adjusting nut 220 is further screwed on the screw 217.
Referring to fig. 1 to 3, the feed inlet 213 on the first feed cylinder 211 is located on one side of the conveyor belt 101, and the feed inlet 213 on the second feed cylinder 212 is located on the other side of the conveyor belt 101.
In this embodiment: in order to improve the accuracy of the samples, a plurality of sets of feed cylinders are designed to sample the samples on both sides of the conveyor belt 101. When the conveyor belt 101 rotates clockwise, the inner sample can be sampled by the first feed cylinder 211, and the outer sample can be sampled by the second feed cylinder 212.
Referring to fig. 1 and 5, the bottoms of the first and second feed cylinders 211 and 212 are respectively provided with a feed pipe 224, and the support frame 103 is provided with a collection box 225 matched with the feed pipes 224 on both sides.

The base 301 is also provided with a plurality of groups of mounting columns 305, and the top plate 302 is mounted on the top of the mounting columns 305; the rotating ring 306 is also provided with a plurality of groups of rotating grooves 307 which are matched with the mounting posts 305, and the conveying arc plate 309 is fixedly arranged on the side surface of the rotating ring 306.
In this embodiment: in order to control the opening and closing of the feed port 213 by rotating the conveying arc plate 309, the conveying arc plate 309 is fixedly provided at the side of the rotating ring 306. When the conveying arc 309 is located at the side of the feed port 213, the feed port 213 is in a closed state at this time. When the conveying arc plate 309 rotates downward below the feed inlet 213, the rotating ring 306 drives the rotating plate 304 to rotate and open the feed inlet 213 through the swing arm 308. Since the feed port 213 is of a downward inclined design, when the conveying arc 309 is rotated downward below the feed port 213, the conveying arc 309 is also inclined. Mineral powder on the conveyor belt 101 is flushed by inertia through the conveying arc 309 into the first feed cylinder 211 and the second feed cylinder 212.
The working principle of the invention is as follows: in use, the apparatus first places the ore feed material on a conveyor belt 101 and conveys it clockwise by means of conveyor rollers 102. When the ore is required to be sampled, the conveying arc plate 309 is rotated downwards, and when the conveying arc plate 309 rotates to the lower part of the feed inlet 213 from the side, the rotating ring 306 drives the rotating plate 304 to rotate and open the feed inlet 213 through the swinging arm 308. Since the feed port 213 is of a downward inclined design, when the conveying arc 309 is rotated downward below the feed port 213, the conveying arc 309 is also inclined. Mineral powder on the conveyor belt 101 is flushed by inertia through the conveying arc 309 into the first feed cylinder 211 and the second feed cylinder 212. Then, the motor 202 is started, and the motor 202 drives the first conveying fan 221 and the second conveying fan 222 on two sides to rotate through the driving gear 203 and the linkage gear 204. Wherein the inner sample can be sampled by the first feed cylinder 211, the outer sample can be sampled by the second feed cylinder 212, and the sampled raw materials are collected by the respective discharge pipes 224 and fall into the collection tank 225. When the motor 202 drives the linkage gear 204 to rotate, the vibration plate 218 can circularly knock the vibration block 214, so that the sample is prevented from adhering to the inner wall to affect the subsequent sampling operation.
According to the invention, the first conveying fan 221 and the second conveying fan 222 on two sides can be synchronously driven through the design of the motor 202 and the rotating frame 201, so that mineral powder on two sides of the conveying belt 101 can be simultaneously sampled in groups. When the conveyor belt 101 rotates clockwise, the inner sample can be sampled by the first feed cylinder 211, and the outer sample can be sampled by the second feed cylinder 212. This stable in structure is effective to also greatly reduced this novel belt sampling device's time cost and human cost. The invention can circularly beat the vibration blocks 214 on the first material conveying cylinder 211 and the second material conveying cylinder 212 through the beating structure 207, thereby avoiding the adhesion of the wetted ore on the inner wall and further improving the conveying effect.
