Description

Technical Field

[0001] This utility model relates to the field of material transportation sampling technology, and in particular to a sampling and preparation device for bulk materials. Background Technology

[0002] Bulk materials such as grain and wood chips are generally transported in material trucks with enclosed compartments. After the materials arrive at their destination, samples are taken before unloading and storing them in the warehouse.

[0003] During unloading from transport vehicles, a sampling worker is typically assigned to manually sample the materials on the unloading conveyor. The method involves periodically shoveling raw materials from the conveyor with a shovel and placing them into a nearby inspection port. Other workers then seal the sampled materials, manually write codes, record vehicle information, and coordinate subsequent testing. This sampling method is inefficient, labor-intensive, and poses safety hazards. Furthermore, it is susceptible to collusion and cheating, causing significant economic losses to the company.

A four-way discharge valve 22 is provided below the receiving bin 21 and between the mixing mixer 14 and the collar-type packing machine 15.

[0016] 2. The sampler 12 includes a collection chamber 121 and a discharge chamber 122 that are interconnected. The collection chamber 121 is a wedge-shaped structure with an opening that gradually decreases from top to bottom, and the discharge chamber 122 is a cylindrical structure. The wedge-shaped structure has an open upper bottom surface 1211, a closed lower bottom surface 1212, a vertical left side surface 1213, and an inclined right side surface 1214. The left side surface 1213 is connected to the side of the cylindrical discharge chamber 122, so that the wood chips can slide down the inclined right side surface from top to bottom into the cylindrical discharge chamber 122 and slide down from the lower opening of the cylindrical discharge chamber 122. A cover plate 1215 is also attached above the upper bottom surface 1211, and the length of the cover plate 1215 is less than the opening length of the upper bottom surface 1211.

[0017] 3. The mixing mixer 14 includes a mixing chamber 141 and a mixing blade 142 located in the mixing chamber 141. The mixing blade 142 is driven to rotate by the mixing motor 143 through chain drive. When the mixing motor 143 rotates forward, it mixes the material sample received in the receiving chamber 21. When the mixing motor 143 rotates in reverse, it pours the mixed material sample from the mixing chamber 141 into the four-way discharge valve 22.

[0018] IV. The lapel-type packaging machine 15 includes a packaging film supply mechanism 151, a forming lapel 152, a heat sealing mechanism 153, and a cutting mechanism 154, which are used to package the material samples conveyed by the four-way discharge valve 22.

[0019] 5. The four-way discharge valve 22 includes a valve body 201 and a valve disc 202. The valve body 21 has four channels, namely a feeding channel 23, a first discharge channel 24, a second discharge channel 25 and a third discharge channel 26.

[0020] 6. The valve disc 202 includes a rotary cylinder 221 and a rotary baffle 222. The rotary baffle 222 is disposed on the output shaft of the rotary cylinder 221. Under the drive of the rotary cylinder 221, the rotary baffle 222 swings left and right.

[0021] The working principle and process of this utility model are as follows: In the upstream process, the material cart unloads the bulk material. During the material's descent and transfer, the sampling motor 7 rotates, driving the sampler 12 to rotate via the sampling drive shaft 10. The length of the cover plate 1215 is shorter than the opening length of the upper bottom surface 1211, facilitating adjustment of the cover plate 1215's position at the opening of the upper bottom surface 1211 to regulate the material receiving speed of the collection bin 121. The cover plate 1215 and the upper bottom surface 1211 can be connected using bolts, nuts, and threaded holes. The sampled material slides down the inclined right side 1214 from top to bottom into the cylindrical discharge bin 122, and then slides from the lower opening of the cylindrical discharge bin 122 onto the conveying device 3. The conveying device 3 transports the sampled material to the receiving hopper 21 of the sample preparation device 2; The receiving hopper 21 sends the material sample into the mixing chamber 141 of the mixing mixer 14. The mixing blades 142 are driven to rotate by the mixing motor 143 through chain drive. When the mixing motor 143 rotates forward, it mixes the wood chip sample received by the receiving hopper 21. When the mixing motor 143 rotates in reverse, it pours the mixed wood chip sample out of the mixing chamber 141 and into the feed channel 23 of the four-way discharge valve 22. The rotary cylinder 221 of valve disc 202 drives the rotary baffle 222 to swing left and right, adjusting the opening size and on / off state of the first discharge channel 24, the second discharge channel 25 and the third discharge channel 26 of the four-way discharge valve 22. The first discharge channel 24 is connected to the forming collar 152 of the collar-type baler 15 through flange 27, the second discharge channel 25 is connected to the outlet of the waste material recycling system 28, and the third discharge channel 26 is connected to the outlet of the custom belt system 29. The packaging film supply mechanism 151 enters the forming collar 152 and wraps the packaging film around the surface of the collar tube to form a packaging bag. The heat sealing mechanism 153 completes the side sealing of the packaging bag. The labeling machine 16 affixes a label to the surface of the packaging bag. The material sample falls into the packaging bag through the collar tube. After the weight reaches the standard, the cutting mechanism 154 cuts the packaging bag and it falls into the finished product conveyor belt 18. The finished product conveyor belt 18 transports the finished product into the sample temporary storage box 17 for storage. The third discharge channel 26 is connected to the outlet of the custom belt system 29, which sends out this part of the material sample for sporadic storage; the surplus material recovery system 28 recovers the excess sample and transports it to the material transfer device.

[0022] The aforementioned material samples may be grains or wood chips.
