[0001] The utility model relates to the technical field of sampling machines, in particular to an intelligent closed sampling machine. Background Art

[0002] A sampling machine is a mechanical device used to automatically or semi-automatically extract samples from bulk materials (such as grain, ore, and chemical raw materials). It can quickly and accurately obtain representative samples of the material for quality inspection, composition analysis, or subsequent process control. Sampling machines are widely used in various fields, including industrial production, warehouse management, and quality inspection.

[0003] In the prior art, for example, the utility model patent with publication number CN201203537Y discloses an automatic grain sampling machine, which includes a longitudinally traveling trolley placed on a longitudinally traveling track, two transversely traveling trolleys placed on the transversely traveling double-sided tracks of the longitudinally traveling trolley, a skewer transmission box lifting mechanism provided on the transversely traveling trolley, a skewer lifting mechanism provided on the skewer transmission box lifting mechanism, and counterweight boxes provided on the two transversely traveling trolleys. When using this machine to take grain samples, the grain transport vehicle drives into a position below the machine, and the machine inserts the skewer into the grain through longitudinal reciprocating motion, transverse reciprocating motion, vertical lifting of the skewer transmission box, and lifting of the skewer, and then sucks the grain sample through the skewer grain sample suction pipe and sends it to the inspection room to complete the sampling.

[0004] However, in actual applications, it is usually necessary to conduct cutting sampling at multiple points on each vehicle. After sampling at one point, the vehicle needs to move forward a certain distance before sampling at the second point. This process must be repeated many times, which is inconvenient. Utility Model Content

[0005] The technical problem to be solved by the utility model is that the existing sampling machine needs to move the vehicle after sampling at each point to sample the next point, which is cumbersome and inefficient.

[0006] In order to solve the above problems, the technical solution of the utility model is: an intelligent closed sampling machine, comprising multiple groups of fixed frames and sampling mechanisms installed on the fixed frames, a canopy is provided on the outside of the fixed frames, the sampling mechanism comprises a slide 1 installed on the fixed frame, a plurality of movable frames are movably provided above the slide 1, a slide 2 is fixedly connected to the upper part of the movable frame, two walking trolleys are movably connected to the outer side of the slide 2, and a steel drag chain is connected to the bottom of the walking trolley, a motor 2 that matches the steel drag chain is installed on one side of the walking trolley, and a skewer transmission box is installed on the other side, a sampling tube is movably installed on one side of the skewer transmission box, and a motor 3 for driving the sampling tube to move up and down is installed at the lower part of the skewer transmission box.

[0007] Furthermore, the four corners of the movable frame are each equipped with a traveling wheel arranged above the slideway 1, and a motor 1 is installed on the movable frame, and a belt transmission assembly is provided between the motor 1 and the traveling wheel.

[0008] Furthermore, the second slideway is perpendicular to the first slideway.

[0009] Furthermore, a limiting rod is provided below the second slideway, and a movable trolley sleeved on the outside of the limiting rod is fixedly connected to one side of the skewer transmission box.

[0010] Furthermore, proximity switches are installed at the four corners of the movable frame and on the side where the two traveling trolleys are close to each other.

[0011] The advantages of the present invention over the prior art are that the present invention can adjust the spacing between multiple movable frames and adjust the sampling tube to different positions, so that the sampling tube can randomly penetrate into the grain, and can complete multi-point sampling in a single time, with high efficiency and speed, cost saving, and simple and convenient operation.

[0017] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0018] like Figure 1As shown, an intelligent closed sampling machine includes multiple sets of fixing frames 1 and sampling mechanisms installed on the fixing frames 1, and a canopy 2 is provided on the outside of the fixing frames 1.

[0019] like Figures 2 to 4 As shown, the sampling mechanism includes a slide 3 installed on a fixed frame 1, and multiple movable frames 4 are movably provided above the slide 3. The four corners of the movable frames 4 are each equipped with a walking wheel 5 arranged above the slide 3, and a motor 6 is installed on the movable frame 4, and a belt transmission assembly is provided between the motor 6 and the walking wheel 5.

[0020] Motor 1 6 drives the running wheel 5 to rotate, which enables the movable frame 4 to move along the slide 3 to adjust the position of the movable frame 4. By installing proximity switches at the four corners of the movable frame 4, collisions between multiple movable frames 4 can be avoided.

[0021] The upper part of the movable frame 4 is fixed with a slideway 2 7 which is perpendicular to the slideway 1 3. Two walking trolleys 8 are movably sleeved on the outer side of the slideway 2 7, and a steel drag chain 9 is connected to the bottom of the walking trolley 8. A motor 2 10 which cooperates with the steel drag chain 9 is installed on one side of the walking trolley 8, and a skewer transmission box 11 is installed on the other side. A limit rod 14 is provided under the slideway 2 7. A moving trolley 15 which is sleeved on the outer side of the limit rod 14 is fixed on one side of the skewer transmission box 11. A sampling tube 12 is movably installed on one side of the skewer transmission box 11, and a motor 3 13 for driving the sampling tube 12 to move up and down is installed on the lower part of the skewer transmission box 11. A proximity switch is installed on the side where the two walking trolleys 8 are close to each other.

[0022] A screw is rotatably installed inside the skewer transmission box 11, and the outer side of the screw is threadedly connected to a slider extending to the outside of the skewer transmission box 11. The upper end of the sampling tube 12 is installed on the slider, and the output shaft of the motor three 13 is connected to the screw by a gear transmission.

[0023] Motor 2 10 drives the traveling trolley 8 along slideway 2 7 to adjust the spacing between the two skewer transmission boxes 11. Motor 3 13 drives the sampling tube 12 up and down to adjust the depth of the sampling tube 12 inserted into the grain. The top of the sampling tube 12 is connected to a negative pressure vacuum adsorption mechanism to achieve cutting sampling of grain samples.

[0024] In specific use, this prototype machine is connected to an unmanned monitoring system, which at least includes a server, a switch, a speed control terminal, an entrance and exit gate, a remote video real-time monitoring system, a vehicle identification camera, a voice dialogue system car identification device, a serial port server, as well as database, operating system and other software.

[0025] The remote video real-time monitoring system at least includes a digital camera, a router, a hard disk, a 16-port hard disk recorder, and a display.

[0026] The voice dialogue system at least includes a voice module, an embedded control system module, an amplifier, a microphone, a wall-mounted loudspeaker, etc.

[0027] The unattended monitoring system can accept instructions from the vehicle control system and upload the information required by the vehicle control system.

[0028] The unattended monitoring system meets the following business processes:

[0029] 1) The vehicle owner, holding relevant documents, pre-registers the vehicle through the tenderer's vehicle control system. The vehicle control system transmits the vehicle pre-registration information to the unmanned monitoring system database through the database intermediate table.

[0030] 2) After the vehicle enters the scanning range of the license plate recognition camera in front of the sampling machine, the license plate recognition camera will automatically scan the license plate number. For vehicles that meet the requirements to enter the sampling machine, the driver will be reminded to enter the sampling area for sampling. The entrance barrier will be raised, and the driver will be reminded by voice to move forward and backward until the vehicle stops steadily on the parking line.

[0031] 3) After the vehicle enters and stops under the sampling machine, the driver walks out of the sampling machine exit to the QR code scanning area to scan the QR code. After the scan is successful, the vehicle control system transmits the information attached to the QR code to the database of the unmanned monitoring system again. The unmanned monitoring system will conduct a secondary check on the vehicle entering the sampling area and the information attached to the QR code scan. After the check is successful, the sampling system automatically starts. If the check is inconsistent, the sampling system will remind the driver through a voice alarm that the sampling cannot be carried out and manual intervention is required for inspection;

[0032] If the second comparison is consistent, the exit gate of the sampling machine will automatically drop down and the system will automatically take samples. For vehicles that are not parked in the correct position, the voice module will automatically remind the driver to move forward or backward. For other social vehicles that enter the scanning range of the license plate recognition camera, the system will automatically remind the vehicle that it is not registered and is not allowed to enter the sampling range. After the sampling is completed, the exit gate will automatically rise, and the driver will be reminded by voice that the sampling is complete and please get in the car and leave to wait for the test results. After the driver leaves, the exit gate of the sampling machine will automatically drop down and wait for the next sampling vehicle to be tested. The testing, weight inspection and other operations after the vehicle sampling are all performed by the tenderer's system.

[0033] This equipment can automatically identify the vehicle model. After one-button start, the sampling tube randomly penetrates into the grain, and uses negative pressure vacuum adsorption to suck the dry bulk grain from the transport vehicle into the grain storage tank. The grain is mixed and separated, and then transported to the laboratory. Sampling, mixing, and transportation are all completed in the same operation. The information is closed to avoid human intervention. It is extremely simple and convenient to use, which greatly improves the efficiency and benefits of grain sampling.

[0034] The sampling process does not require repeated operations and does not require moving the transport vehicle. The sampling efficiency is high, the speed is fast, the cost is saved, and the operation is simple and convenient.
