[0051] The sliding rod 23 is fixedly connected to the moving end of the arc-shaped telescopic plate 22, and the end of the sliding rod 23 is slidably connected to the inner wall of the protective cover 3. A second spring 24 is fixedly connected to the side wall of the sliding rod 23, and one end of the second spring 24 is fixedly connected to the inner wall of the protective cover 3.

The material barrel 7 is fixedly connected to the side wall of the moving rod 30. The circumferential wall of the push plate 8 contacts the inner ring wall of the material barrel 7, and the diameter of the outer ring wall of the material barrel 7 is smaller than the diameter of the circular through hole 6.

When the material barrel 7 drives the middle part of the chemical hazardous goods to move and makes the middle part of the chemical hazardous goods contact the pushing plate 8, the pushing plate 8 prevents the middle part of the chemical hazardous goods from continuing to move with the material barrel 7. The pushing plate 8 blocks the middle part of the chemical hazardous goods and pushes the chemical hazardous goods out of the material barrel 7, thereby realizing the sampling of the middle part of the granular chemical hazardous goods.

[0055] The end faces of the material taking barrel 7 and the clamping plate 5 are arranged at an angle, and an arc-shaped collecting plate 31 is arranged on the lower side of the port of the material taking barrel 7 close to the clamping plate 5.

[0056] The third spring 34 is pulled downward by the sliding plate 33 so that the lower end surface of the protective cover 3 is fitted with the bottom of the fixed seat 1, thereby preventing the protective cover 3 from moving.

[0057] Working principle: The bottom plate of the fixing seat 1 is bolted to one side of the existing chemical hazardous goods production conveyor belt, and the conveyor belt is located directly below the protective cover 3. When the conveyor belt moves the loaded chemical hazardous goods to the bottom of the protective cover 3, the first electric telescopic rod 2 and the third electric telescopic rod 42 are started, the first electric telescopic rod 2 pushes the connecting plate 4 downward, and drives the sliding plate 33 to slide downward, and the protective cover 3 will slide downward due to the action of gravity during the downward movement of the connecting plate 4, and the third electric telescopic rod 42 pulls the fixing block 14 to one side, so that the cover plate 13 moves to the receiving groove on the side wall of the strip through hole 12. At this time, the strip through hole 12 is open. When the protective cover 3 When the lower surface contacts the bottom of the fixed seat 1, the moving end of the first electric telescopic rod 2 continues to push the clamping mechanism downward and drives the sliding plate 33 to slide downward, and the sliding plate 33 pulls the lower end of the third spring 34 downward, so that the third spring 34 is in a stretched state, and through the pulling force of the third spring 34, the third spring 34 pulls the protective cover 3 downward, so that the lower end surface of the protective cover 3 is in contact with the bottom of the fixed seat 1, thereby preventing the protective cover 3 from moving. A notch is provided on the side wall of the protective cover 3 for replacing the transport belt, and the notch is connected to the strip through hole 12, so that the protective cover 3 is convenient for covering the transport belt. At the same time, the container loaded with granular chemical hazardous materials transported on the transport belt is located in the protective cover 3.

[0058] When the lower end surface of the push block 41 contacts the bottom of the fixed seat 1, the protective cover 3 moves downward, so that the bottom of the fixed seat 1 pushes the push block 41 upward, and pushes the blocking block 11 upward through the push rod 40. When the lower end of the blocking block 11 is located on the upper side of the air outlet 10, the inert gas in the inert gas loading box 9 is discharged through the air outlet 10 and enters the protective cover 3, thereby reducing the air in the protective cover 3, so that the container loaded with granular chemical hazardous substances is located in the inert gas in the protective cover 3. At this time, the first electric telescopic rod 2 continues to push the connecting plate 4 downward. When the two clamping plates 5 are inserted into the container loaded with granular chemical hazardous substances, the third spring The spring 34 is in a fully extended state, and the servo motor 16 is started at the same time. The output shaft of the servo motor 16 drives the lead screw 15 to rotate. Through the limitation of the thread and the slide groove on the connecting plate 4, the lead screw 15 drives the two clamping plates 5 to move toward each other. In the process of the two clamping plates 5 moving toward each other, the two clamping plates 5 clamp and fix the granular chemical hazardous materials, and make the clamped chemical hazardous materials located in the circular through hole 6, and the edges of the chemical hazardous materials protrude to the outside of the clamping plate 5 through the circular through hole 6, and the ends of the granular chemical hazardous materials protrude to the outside of the clamping plate 5 through the circular through hole 6, which can effectively prevent the clamping force of the clamping plate 5 from being too large, causing the granular chemical hazardous materials to slide to the side.

[0059] At this time, the moving end of the first electric telescopic rod 2 pulls the connecting plate 4 upward, and drives the clamping plate 5 and the clamped chemical hazardous articles to move upward, and the lower end of the third spring 34 moves upward. When the third spring 34 is in a natural state, at this time, the protective cover 3 is pushed upward by the upward elastic force of the third spring 34. When the first electric telescopic rod 2 drives the connecting plate 4, the clamping plate 5 and the protective cover 3 to continue to move upward, when the protective cover 3 moves to the upper side loaded with granular chemical hazardous articles, at this time, the third electric telescopic rod 42 is started, and the third electric telescopic rod 42 pushes the two cover plates 13 toward each other, so that the cover plates 13 cover the strip through holes 12, and the bottom of the protective cover 3 is closed, thereby preventing the inert gas in the protective cover 3 from continuing to leak outward, and the limit plate 25 is separated from the pushing of the push plate 26, and in the process of the connecting plate 4 moving upward, the second spring 24 pushes the sliding rod 23 to the clamping The tightening plate 5 pushes and drives one end of the arc-shaped telescopic plate 22 to extend toward the clamping plate 5, and when the protective cover 3 contacts the top of the fixing seat 1, due to the blocking of the protective cover 3 by the top of the fixing seat 1, the position of the protective cover 3 remains unchanged during the process in which the first electric telescopic rod 2 drives the connecting plate 4 to move upward, and when the connecting plate 4 drives the clamping plate 5 and the limiting rod 19 to move upward, and the upper end of the limiting rod 19 contacts the protective cover 3, due to the blocking of the limiting rod 19 by the top of the protective cover 3, the clamping plate 5 moves downward relative to the clamping plate 5 during the upward movement, and when the cutting knife 17 passes through the granular chemical hazardous substances protruding from the circular through hole 6, the cutting knife 17 cuts off the granular chemical hazardous substances protruding from the circular through hole 6, and the cut external chemical hazardous substances fall downward onto the arc-shaped telescopic plate 22, and slide into the first collecting box 28 through the arc-shaped telescopic plate 22 and the first discharge pipe 27.

[0060] When the cutting knife 17 moves to the lower side of the cut chemical hazardous article, at this time, the baffle 18 covers one side of the cut chemical hazardous article, and at the same time the first electric telescopic rod 2 stops moving, and the second electric telescopic rod 29 is opened, the second electric telescopic rod 29 pushes the material taking barrel 7 in the direction of the clamping plate 5, the material taking barrel 7 passes through the circular through hole 6 and the end of the material taking barrel 7 is inserted into the chemical hazardous article through the cutting part of the granular chemical hazardous article. Due to the blocking effect of the baffle 18, when the end of the material taking barrel 7 contacts the side wall of the baffle 18, the material taking barrel 7 completes the interception of the middle part of the granular chemical hazardous article. At this time, the second electric telescopic rod 29 drives the middle part of the intercepted granular chemical hazardous article to be pushed to one side, and when the material taking barrel 7 drives the middle part of the chemical hazardous article to move and makes the middle part of the chemical hazardous article contact with the pushing plate 8, the pushing plate 8 prevents the middle part of the chemical hazardous article from continuing to move with the material taking barrel 7, thereby pushing the chemical hazardous article through the pushing plate 8. The blocking of the middle part of the hazardous chemical goods pushes the hazardous chemical goods out of the material dispensing barrel 7, thereby realizing sampling of the middle part of the granular hazardous chemical goods. When the material dispensing barrel 7 moves out of the circular through hole 6, the first electric telescopic rod 2 continues to drive the clamping plate 5 to move upward, so that the cutting knife 17 continues to cut the protruding part of the granular hazardous chemical goods on the lower side through the circular through hole 6, and collects the cut part, thereby realizing the distinguished collection and differentiated inspection of the outer layer and the middle part of the hazardous chemical goods, so as to facilitate the staff to inspect the surface of the hazardous chemical goods so that the staff can analyze the production status of the hazardous chemical goods in the environment where they are located, so as to facilitate the staff to adjust the environment where the hazardous chemical goods are produced, thereby reducing the influence of the air on the hazardous chemical goods during the production process, and at the same time, the staff can inspect the middle part of the hazardous chemical goods, so as to facilitate the staff to inspect the quality of the hazardous chemical goods.

[0061] Embodiment 2

[0062] The following technical features are added on the basis of the first embodiment:

[0063] A chemical hazardous goods clamping device for safe production, a thermal ink loading box 35 is fixedly connected to the top of the protective cover 3, the thermal ink loading box 35 is used to load thermal ink, and a first liquid discharge pipe 36 is fixedly connected to the lower end of the thermal ink loading box 35.

[0064] The lower end of the first drainage pipe 36 is fixedly connected to the clamping plate 5, and a cavity 37 is opened in the clamping plate 5. The first drainage pipe 36 is connected to the cavity 37. The second drainage pipe 38 is fixedly connected to the clamping plate 5. The upper end of the second drainage pipe 38 is connected to the cavity 37. The lower end of the second drainage pipe 38 is fixedly connected to the inner wall of the protective cover 3, and a marking cotton 39 is fixedly connected to the inner wall of the protective cover 3. The marking cotton 39 is located directly below the second drainage pipe 38. The cavity The longitudinal section of 37 is U-shaped, and the ends of the first drainage pipe 36 and the second drainage pipe 38 are fixedly connected to the top of the clamping plate 5, and the first drainage pipe 36 and the second drainage pipe 38 are respectively located at the two ends of the cavity 37 and are connected to the cavity 37, wherein the material of the clamping plate 5 is a heat-conducting material, which facilitates the clamping plate 5 to transfer heat to the cavity 37, wherein the second drainage pipe 38 is provided with an automatic control valve, and the automatic control valve is used to control the intermittent opening of the second drainage pipe 38.

[0065] The lower section of the first liquid discharge pipe 36 and the upper section of the second liquid discharge pipe 38 are both telescopic hoses.

[0066] Working principle: Thermosensitive ink is injected into the thermosensitive ink loading box 35, and the thermosensitive ink flows downward into the cavity 37 through the first drainage pipe 36 and stays in the cavity 37, wherein the side wall of the thermosensitive ink loading box 35 is fixedly connected with an injection pipe, the end of the injection pipe penetrates the side wall of the protective cover 3 and is inserted with a piston, so as to facilitate the injection of thermosensitive ink into the thermosensitive ink loading box 35. At the same time, when the automatic control valve in the second drainage pipe 38 is opened, the thermosensitive ink in the cavity 37 flows downward through the second drainage pipe 38 and drips onto the marking cotton 39. When the conveyor belt moves the container loaded with chemical hazardous substances in the protective cover 3, and the container loaded with chemical hazardous substances and the marking cotton 39 are moved, the thermosensitive ink in the cavity 37 flows downward through the second drainage pipe 38 and drips onto the marking cotton 39. 9, the marking cotton 39 applies the heat-sensitive ink to the container loaded with chemical hazardous materials for marking. At this time, the first electric telescopic rod 2 drives the protective cover 3 to move upward, so as to facilitate the marked container to move out of the protective cover 3. When the chemical hazardous materials in the marked container are in the detection process and the monitoring data is abnormal, the staff can find the chemical hazardous materials container with abnormal data according to the number of sampling and the marked arrangement position. At the same time, the chemical hazardous materials in the container between the marked container and the adjacent marked container that have not been sampled can be sampled and compared, so as to facilitate the staff to check and separate the chemical hazardous materials with abnormal detection data and quality.

[0067] When the cutting knife 17 cuts the granular chemical hazardous materials protruding from the circular through hole 6 on the clamping plate 5, friction will occur between the cutting knife 17 and the chemical hazardous materials. At the same time, friction and heat will also occur when the cutting knife 17 slides on the clamping plate 5. Some chemical hazardous materials will undergo chemical reactions such as decomposition and explosion at high temperatures, such as above 20°C. Therefore, when the temperature on the clamping plate 5 is too high or the temperature inside the protective cover 3 is too high, the clamping plate 5 transfers the heat to the heat-sensitive ink in the cavity 37. The heat-sensitive ink will react with the temperature when sensing the temperature change. In the process, color change will occur, and when the marking cotton 39 applies the color-changed heat-sensitive ink to the outer surface of the container containing chemical hazardous substances, the personnel can distinguish the temperature inside the clamping plate 5 and the protective cover 3 by the color marked on the surface of the container, so as to facilitate the staff to replace the clamping plate 5 or adjust the temperature inside the protective cover 3, thereby avoiding the temperature inside the protective cover 3 being too high or the temperature on the clamping plate 5 being too high, which may cause the granular chemical hazardous substances to react chemically due to excessive temperature when sampling, thereby ensuring the accuracy of the data of the sampled chemical hazardous substances during detection.

[0068] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
