Description

Technical Field

[0001] This utility model relates to a device for sampling grain transported by ships in ports, belonging to the technical field of port grain testing equipment. Background Technology

[0002] After grain arrives at port, it needs to be sampled to test its quality. Traditional grain sampling involves manual boarding, using a sampling probe, dividing the area into different compartments, manually estimating the weight, and then taking samples. Testing personnel use probes to sample in sections and layers, then label and bag them. According to sampling standards, each ship requires dozens to hundreds of samples, with a total weight of several hundred to several thousand kilograms. This process is tedious and time-consuming. Traditional sampling methods are labor-intensive and time-consuming, significantly impacting ship loading and unloading operations, resulting in prolonged berth occupancy and low berth utilization. The total sampling weight per 10,000 tons of ship is approximately several hundred kilograms. Furthermore, the outdoor work environment is harsh, posing safety hazards to personnel, and the sampling time is long with low levels of standardized operation. Manual sampling also carries the risk of secondary contamination of the samples. Therefore, improvements are urgently needed. Utility Model Content

This grain sampling device can replace manual sampling of grain, standardize grain testing, improve the speed and timeliness of grain inspection, save sampling labor costs, and reduce the labor intensity of inspectors.

[0004] The technical solution to the above technical problem is:

[0005] A high-efficiency port ship grain sampling device includes a servo motor, a planetary reducer, a coupling, a spiral sampler, a mounting flange, a guide tube, and a sample storage cabinet. The servo motor is connected to the planetary reducer, the output shaft of the planetary reducer is connected to the input end of the coupling, the output end of the coupling is connected to the spiral sampler, the middle part of the spiral sampler is fixed to the outer wall of the grain loading funnel through the mounting flange, the upper end of the guide tube is connected to the spiral sampler outside the grain loading funnel, and the lower end of the guide tube is connected to the sample storage cabinet.

[0006] In the aforementioned high-efficiency port ship grain sampling device, the inner hole of the mounting flange is fitted onto the outer periphery of the spiral sampler, the plane of the mounting flange is inclined at an angle to the axis of the spiral sampler, the plane of the mounting flange is in close contact with the lower part of the outer wall of the grain loading funnel, and the mounting flange is fixedly connected to the outer wall of the grain loading funnel by mounting bolts.

[0007] The aforementioned high-efficiency port ship grain sampling device comprises a spiral sampler consisting of a sampling tube, a connecting flange, a rotating shaft, and auger blades. The sampling tube is cylindrical, with a connecting flange welded to its front end. The connecting flange is bolted to the housing of the coupling. The rotating shaft is located inside the sampling tube, with one end connected to the output end of the coupling and the other end rotatably connected to the bottom of the sampling tube by a bearing. The auger blades are mounted on the rotating shaft. The lower side wall of the sampling tube has a sampling port, which is an elongated hole extending along the length of the sampling tube and communicating with the grain stored inside the grain loading hopper.

[0008] In the aforementioned high-efficiency port vessel grain sampling device, the conduit is vertically downward and the sample storage cabinet is placed at the bottom of the funnel support below the grain loading funnel.

[0016] This utility model consists of a servo motor 1, a planetary reducer 2, a coupling 3, a spiral sampler 4, a mounting flange 5, a conduit 6, and a sample storage cabinet 7.

[0017] Figure 1 The display shows that the servo motor 1 is connected to the planetary reducer 2, the output shaft of the planetary reducer 2 is connected to the input end of the coupling 3, the output end of the coupling 3 is connected to the spiral sampler 4, and the middle part of the spiral sampler 4 is fixed to the outer wall of the grain loading hopper 13 by the mounting flange 5.

[0018] Figure 1 The upper end of the conduit 6 is connected to the spiral sampler 4 outside the grain loading funnel 13, and the lower end of the conduit 6 is connected to the sample storage cabinet 7. During sampling, the servo motor 1 drives the spiral sampler 4 to sample through the planetary reducer 2 and coupling 3. The spiral sampler 4 transports the sampled grain into the conduit 6, and the grain falls from the conduit 6 into the sample storage cabinet 7 for storage and testing.

[0019] Figure 1 As shown, the inner hole of the mounting flange 5 is fitted around the outer periphery of the spiral sampler 4, the plane of the mounting flange 5 is inclined at an angle to the spiral sampler 4, the plane of the mounting flange 5 is in close contact with the lower part of the outer wall of the grain loading funnel 13, and the mounting flange 5 is fixedly connected to the outer wall of the grain loading funnel by mounting bolts.

[0020] Figure 2 The spiral sampler 4 consists of a sampling tube 8, a connecting flange 9, a rotating shaft 10, and auger blades 11. The sampling tube 8 is cylindrical, with the connecting flange 9 welded to its front end. The connecting flange 9 is bolted to the housing of the coupling 3. The rotating shaft 10 is located inside the sampling tube 8. One end of the rotating shaft 10 is connected to the output end of the coupling 3, and the other end is rotatably connected to the bottom of the sampling tube 8 by a bearing. The auger blades 11 are mounted on the rotating shaft 10. The coupling 3 drives the rotating shaft 10 of the spiral sampler 4 to rotate, and the auger blades 11 on the rotating shaft 10 sample as the rotating shaft 10 rotates.

[0021] Figure 1 , 2 The sampling tube 8 has a sampling port 12 on its lower side wall. The sampling port 12 is an elongated hole that runs along the length of the sampling tube 8. The sampling port 12 is connected to the grain stored inside the grain loading funnel 13. The grain in the grain loading funnel 13 enters the sampling tube 8 through the sampling port 12. The auger blades 11 rotate to transport the grain that has entered the sampling tube 8 outward.

[0022] Figure 3 As shown, the conduit 6 connected to the spiral sampler 4 points vertically downwards, and the sample storage cabinet 7 is placed at the bottom of the funnel support 14 below the grain loading funnel 13. Grain samples fall into the sample storage cabinet 7 through the conduit 6 for storage and testing.

[0023] The usage process of this utility model is as follows:

[0024] After the grain loading and transportation begins, the grab bucket loads grain into the grain loading funnel 13. Once fully loaded, the transport vehicle waits to be loaded below the grain loading funnel 13. The device is activated at the same time the valve of the grain loading funnel 13 is opened to release the grain.

[0025] The servo motor 1 rotates, driving the spiral sampler 4 to rotate and spin out the grain sample from the grain loading funnel 13. The grain sample flows into the sample storage cabinet 7 through the conduit 6, completing one sampling.

[0026] The application of this grain sampling device will effectively reduce on-site operation time. Traditionally, manual sampling is performed once every 10 grab buckets (approximately 200 tons) are lowered to the ground, with each sampling taking about 5 minutes. A 10,000-ton ship's hold would require approximately 50 manual samplings, totaling about 250 minutes (4.17 hours). It is estimated that this will reduce operation time by 4.17 hours per ship unloaded. Therefore, the equipment will further improve terminal utilization, increase port throughput and revenue. During the unloading process, there is no need to lower the grab buckets to the ground for manual sampling, further ensuring on-site safety.
