Description

Technical Field

[0001] This utility model relates to the field of bulk cargo sampling technology at docks, and in particular to a general-purpose automated bulk cargo sampling device for docks. Background Technology

[0002] In both coal trading and application, coal testing indicators are essential, and coal sampling is a crucial and indispensable step. Currently, goods are primarily transported horizontally by vehicle, and during peak production periods, up to a dozen production lines can operate simultaneously. Third-party testing agencies often have numerous sampling points at the work site, frequently resulting in mixed human and machine operations. This poses significant challenges to the company's safety management, presents substantial safety risks, and manual sampling is inefficient, labor-intensive, and impacts production efficiency.

[0003] To optimize the sampling process, reduce safety risks for sampling personnel, and improve the level of automation, those skilled in the art provide a general-purpose automated sampling device for bulk cargo at terminals. This device enables automated sampling of bulk cargo during transportation, replacing manual sampling. Summary of the Invention

[0004] The purpose of this invention is to solve the above-mentioned technical problems and provide a general-purpose automated sampling device for bulk cargo at docks.

[0005] To achieve the above technical objectives and requirements, the technical solution adopted by this utility model is as follows: a general-purpose automated sampling device for bulk cargo at a dock, comprising a left support and a hopper support. A transmission sampling mechanism is provided on the left support and the hopper support. A bellows cover is provided above the transmission sampling mechanism. The transmission sampling mechanism includes an X-axis assembly, a Z-axis assembly is vertically arranged on the X-axis assembly, and a sampling head module is provided at the lower end of the Z-axis assembly. A sample collection mechanism is provided on the hopper support. The sample collection mechanism includes a receiving hopper located above the inner side of the hopper support and a hopper located within the hollow longitudinal beam of the hopper support. A weighing mechanism is provided at the bottom of the hopper. A discharge hopper is provided on one side of the bottom of the hopper. A discharge assembly is provided at the connection between the hopper and the discharge hopper. A sampling bag receiving port is provided below the discharge hopper, and a sampling bag is fitted onto the receiving port. Sampling bag fixing assemblies are symmetrically arranged on both sides of the discharge hopper. A top cover is provided on the hopper support above the discharge hopper, and a weighing instrument is provided on the hopper support.

[0006] Preferably, the discharge assembly includes a storage door and an adjusting rod. The storage door is connected to the side wall of the hollow longitudinal beam via a hinge. A support is provided on the storage door, and a fixing block is provided on the support. A second support is provided on the side wall of the hollow longitudinal beam, and an adjusting block is provided on the second support. The lower end of the adjusting rod passes through the adjusting block and is mounted on the fixing block, while the upper end is provided with an adjusting handwheel. The adjusting rod is threadedly connected to the adjusting block. When the hopper reaches the set sampling mass, the system provides a voice prompt for sampling. The operator rotates the adjusting handwheel to open the storage door, discharges the sample, and then resets and closes the storage door.

[0007] Preferably, the sampling bag fixing assembly includes fixing brackets symmetrically arranged on both sides of the discharge hopper, guide rods symmetrically arranged at the bottom of the fixing brackets, insertion rods at the front end of the guide rods, abutment rods at the front end of the insertion rods, and connecting rods at the rear end of the insertion rods. The front end of the pull rod is hinged to the guide rods and the connecting rods respectively.

[0008] Preferably, the sampling head module includes a bucket-type sampling head, which is connected to the adjusting column of the Z-axis assembly via a bent rod. An electric push rod is provided on one side of the adjusting column, and the lower end of the electric push rod is connected to the middle of the bent rod via a connecting arm. An ultrasonic sensor is provided at the lower end of the adjusting column.

[0009] Preferably, a movable shovel is provided between the hopper support and the left support.

[0010] Preferably, the two sides of the hopper support are respectively equipped with laser rangefinders with digital switch output function, and the two laser rangefinders are installed in a fan shape to measure two points: the front and the rear of the vehicle.

[0011] Compared with the traditional structure, the beneficial effects of this utility model are:

[0012] 1. This utility model has a reasonable structural design. Coal is collected through a receiving hopper and a silo. A sampling bag receiving port is reserved at the bottom of the discharge hopper, and a weighing sensor is installed at the bottom of the silo. When the set sampling mass is reached, the system alarms to prompt sampling. On-site sampling personnel can discharge materials in a concentrated manner, reducing the frequency of material receiving, reducing labor intensity, reducing the phenomenon of human-machine mixed operation, and improving production efficiency. The sample collection equipment is made of 304 stainless steel, which is non-stick, corrosion-resistant, and easy to clean.

[0013] 2. By using two laser rangefinders with digital switch output functions installed in a fan shape, the front and rear of the vehicle are measured. The digital switch output points of the two rangefinders are connected in series, which cleverly solves the problem of single-point vehicle positioning and achieves the goal of accurate vehicle positioning.

[0014] 3. Sampling is carried out using a bucket mechanism. The rotation of the bucket is controlled by an electric push rod. The height of the coal surface is detected by an ultrasonic radar sensor and fed back to the PLC to calculate the starting sampling height. This method is easy to operate, reduces the safety risks for sampling personnel, and improves the degree of automation in sampling. Attached Figure Description

[0021] The present invention will be further described below.

[0022] See attached document Figure 1 , Figure 2 A general-purpose automated sampling device for bulk cargo at a dock includes a left support 1 and a hopper support 4. A transmission sampling mechanism 2 is installed on the left support 1 and the hopper support 4. A bellows protective cover 6 is installed above the transmission sampling mechanism 2. The transmission sampling mechanism 2 includes an X-axis assembly 21. A Z-axis assembly 22 is vertically installed on the X-axis assembly 21. A sampling head module 3 is installed at the lower end of the Z-axis assembly 22. A sample collection mechanism 5 is installed on the hopper support 4.

[0023] like Figure 3 , Figure 5 As shown, the sample collection mechanism 5 includes a receiving hopper 51 located above the inner side of the hopper support 4, and a hopper 52 located inside the hollow longitudinal beam 41 of the hopper support 4. A weighing mechanism 53 is provided at the bottom of the hopper 52, and a discharge hopper 54 is provided on one side of the bottom of the hopper 52. A discharge component 55 is provided at the connection between the hopper 52 and the discharge hopper 54. A sampling bag receiving port is provided below the discharge hopper 54, and a sampling bag 57 is fitted on the receiving port. Sampling bag fixing components 56 are symmetrically arranged on both sides of the discharge hopper 54. A top cover 59 is provided on the hopper support 4 above the discharge hopper 54, and a weighing instrument 58 is provided on the hopper support 4, which can set the sampling mass.

[0024] The discharge assembly 55 includes a storage door 551 and an adjusting rod 552. The storage door 551 is hinged to the side wall of the hollow longitudinal beam 41. A support is provided on the storage door 551, and a fixing block 555 is provided on the support. A second support is provided on the side wall of the hollow longitudinal beam 41, and an adjusting block 554 is provided on the second support. The lower end of the adjusting rod 552 passes through the adjusting block 554 and is mounted on the fixing block 555. An adjusting handwheel 553 is provided at the upper end. The adjusting rod 552 is threadedly connected to the adjusting block 554. When the hopper reaches the set sampling mass, the system will prompt the operator to take a sample. The operator will turn the adjusting handwheel to open the storage door 551, discharge the sample, and then reset and close the storage door 551.

[0025] The sampling bag fixing assembly 56 includes fixing brackets 561 symmetrically arranged on both sides of the discharge hopper 54. The bottom of the fixing brackets 561 is symmetrically arranged with guide rods 562. The front end of the guide rods 562 is provided with an insertion rod 565. The front end of the insertion rod 565 is provided with an abutment rod. The rear end of the insertion rod 565 is provided with a connecting rod 563. The front end of the pull rod 564 is hinged to the guide rod 562 and the connecting rod 563 respectively.

[0026] like Figure 4 As shown, the sampling head module 3 includes a bucket-type sampling head 33, which is connected to the adjusting column of the Z-axis assembly 22 via a bent rod 35. An electric push rod 31 is provided on one side of the adjusting column 221, and the lower end of the electric push rod 31 is connected to the middle of the bent rod 35 via a connecting arm 34. An ultrasonic sensor 32 is provided at the lower end of the adjusting column 31.

[0027] A movable shovel 7 is installed between the hopper support 4 and the left support 1. The sampling device can be flexibly deployed according to the change of the sampling route, reducing the overall investment cost and effectively improving the equipment utilization rate. The movable shovel 7 is designed to be separate from the sampling device. When not moving, the shovel must be placed in a designated position.

[0028] The two laser rangefinders 8 with digital switch output function are respectively installed on both sides of the hopper support 4. The two laser rangefinders 8 are installed in a fan shape and are used to measure two points: the front and the rear of the vehicle.

[0029] In practice, the sampling equipment is a bridge gantry structure. When the target vehicle enters the designated sampling area and the vehicle stops and stabilizes, the system starts working. The sampling head module moves horizontally from the waiting area to above the vehicle body. The upper and lower modules receive the system's descent command and begin to descend. When the sampling head descends to the material surface, the upper and lower modules automatically switch to a slow feeding mode. Sampling is completed. The sampling head rises and returns to the top of the receiving hopper to discharge the material. After discharge, it waits in place for the next operating command.

[0030] The X-axis assembly 21 employs a rack and pinion transmission mechanism, with a servo motor driving a planetary reducer, which in turn drives a gear transmission, guiding movement via a linear guide rail. The X-axis travel allows sampling within a 1-meter width of the vehicle's cargo compartment, using the compartment's center as a reference. The Z-axis assembly 22 also uses a rack and pinion mechanism, with a servo motor controlling the sampling coal height range of 3.4M to 4.3M. An automatic lubrication system automatically lubricates the X and Z axes at regular intervals based on operating time, ensuring smooth rack and pinion operation. To prevent dust ingress, the transmission sampling mechanism 2 features a sealed design with a bellows-shaped protective cover 6. The feed inlet of the receiving hopper 51 is located at the bottom of the bellows-shaped protective cover 6, preventing rainwater from entering.

[0031] The receiving hopper 51 is similar to a truck receiving hopper. Samples enter the silo 52 through the receiving hopper 51. The silo 52 is located inside the hollow longitudinal beam 41 and connected to the hollow longitudinal beam 41 via a bottom support. The silo 52 can store a minimum weight of 100 kg. A weighing sensor is installed at the bottom of the silo 52. When the set sampling weight is reached, the system alarms to prompt sampling. The operator turns the handwheel to open the storage door 551, discharges the sample, and then resets and closes the storage door 551. On-site sampling personnel can collect samples centrally, reducing the frequency of receiving. The sample collection equipment is made of 304 stainless steel, which is non-stick, corrosion-resistant, and easy to clean.

[0032] By using two laser rangefinders 8 with digital switch output function installed in a fan shape, the front and rear of the vehicle are measured. The digital switch output points of the two rangefinders are connected in series, which cleverly solves the problem of single-point vehicle positioning and achieves the goal of accurate vehicle positioning.

[0033] Two ultrasonic sensors 32 are installed above the bucket. When the Z-axis descends to 40 cm from the material surface, the Z-axis stops descending, and the electric push rod 31 pushes the bucket-type sampling head 33 to start operating.

[0034] The above embodiments of this utility model are merely examples to clearly illustrate this utility model, and are not intended to limit the scope of protection of this utility model. All equivalent technical solutions also fall within the scope of this utility model, and the patent protection scope of this utility model should be defined by each claim.
