Abstract
Description
Technical Field
[0001] This utility model relates to the field of grain sampling technology, and in particular to an automated grain sampling device. Background Technology
[0002] Grain sampling is a crucial task in the production, storage, and trading of grain. Accurate grain sampling provides a reliable basis for grain quality testing, evaluation, and subsequent decision-making. For example, during grain storage, it is necessary to regularly sample and test the grain to understand indicators such as moisture content, pest infestation, and degree of mold, so as to take appropriate measures in a timely manner to ensure the quality and safety of the grain.
[0003] Traditional grain sampling methods mostly rely on manual operation. Operators need to manually insert sampling tools into the grain pile to collect samples, and then transfer the samples to the collection container. When multiple samples need to be collected, operators need to frequently change sampling tools and collection containers, which makes the entire sampling process extremely labor-intensive. Especially in large-scale grain storage warehouses or grain trading venues, long-term manual sampling operations can easily cause operator fatigue, thereby affecting the efficiency and accuracy of sampling. Utility Model Content
[0004] To solve the above-mentioned technical problems, this utility model provides an automated grain sampling device.
[0005] This utility model is achieved using the following technical solution: an automated grain sampling device, comprising a support plate, a vertical trough frame fixedly connected to the upper surface of the support plate, an mounting plate fixedly connected to the upper surface of the vertical trough frame, a motor fixedly connected to the upper surface of the mounting plate, a lead screw fixedly connected to the output end of the motor, a mounting plate threadedly connected to the outer surface of the lead screw, a right-angle frame fixedly connected to the lower surface of the mounting plate, a turntable mechanism fixedly connected to the surface of the right-angle frame, a sampling pump fixedly mounted on the upper surface of the mounting plate by bolts, an inlet pipe fixedly connected to the input end of the sampling pump, and a delivery pipe fixedly connected to the output end of the sampling pump.
[0006] The above technical solution enables automated height-adjustable sampling. The sampling height is accurately controlled by the cooperation of the motor and the lead screw. The turntable mechanism can collect multiple different grain samples at once, reducing the workload of manual operation and speeding up the sampling process.
[0007] As a further improvement to the above solution, the turntable mechanism includes a chassis, a second motor is provided on the upper surface of the chassis, a movable disk is fixedly connected to the output end of the second motor, a circular sliding groove is provided on the upper surface of the chassis, a sliding rod is fixedly connected to the lower surface of the movable disk, and several sample storage cylinders are fixedly connected to the upper surface of the movable disk.
[0008] The above technical solution allows for multiple samplings to be completed at once, eliminating the need for personnel to retrieve samples after each sampling and perform secondary sampling, thus improving sampling efficiency and enabling the orderly storage of multiple samples.
[0009] As a further improvement to the above solution, the slide rod is slidably connected to the inside of the circular groove.
[0010] The above technical solution ensures the stability of the rotating disc, thereby ensuring that the sample storage cylinder can accurately rotate to the bottom of the sample delivery tube to receive the sample, thus improving the accuracy of sampling and storage.
[0011] As a further improvement to the above solution, the mounting plate is slidably connected to the inside of the vertical slot frame.
[0012] The above technical solution ensures the stability of the mounting plate in the vertical direction, enabling the sampling pump and its connected inlet and delivery pipes to accurately reach the appropriate sampling and delivery positions.
[0013] As a further improvement to the above solution, a pipe seat is fixedly connected to the outer surface of the injection tube, and the pipe seat is fixedly connected to the upper surface of the mounting plate.
[0014] As a further improvement to the above solution, diagonal bracing brackets are fixedly connected to both sides of the outer surface of the vertical slot frame, and the diagonal bracing brackets are fixedly connected to the upper surface of the support plate.
[0015] As a further improvement to the above solution, a position sensor is fixedly connected to the upper surface of the second motor.
[0016] The above technical solution improves the accuracy of sample reception in the sample storage cylinder, avoiding sample leakage or failure to accurately enter the sample storage cylinder due to inaccurate positioning. The position sensor is an Omron E2EX10D1 M1 Z, which can accurately detect the approach of the target object and is well applicable to detecting the position of the sample storage cylinder in the turntable mechanism.
[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0018] This invention features a turntable mechanism. A second motor drives the movable disc to rotate, and a sliding rod on the lower surface of the movable disc slides within a circular groove on the upper surface of the base, ensuring stable rotation. This allows for the orderly rotation of different sample storage cylinders to the sample delivery tube for receiving samples, enabling the simultaneous collection of multiple different grain samples. This eliminates the need for repeated manual container changes, reducing labor and accelerating the sampling process. The first motor drives a lead screw, controlling the descent height of the mounting plate. Compared to manual height adjustment, this method is more precise and stable, reducing sampling height errors caused by human factors. This allows for accurate adjustment of the sampling pump and sample delivery tube height, ensuring the sample delivery tube can sample grains at the appropriate height. Attached Figure Description

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0027] Example:
[0028] Please combine Figure 1-5An automated grain sampling device according to this embodiment includes a support plate 1. A vertical trough frame 2 is fixedly connected to the upper surface of the support plate 1. A mounting plate 3 is fixedly connected to the upper surface of the vertical trough frame 2. A motor 4 is fixedly connected to the upper surface of the mounting plate 3. A lead screw 5 is fixedly connected to the output end of the motor 4. A mounting plate 6 is threadedly connected to the outer surface of the lead screw 5. A right-angle frame 7 is fixedly connected to the lower surface of the mounting plate 6. A turntable mechanism 8 is fixedly connected to the surface of the right-angle frame 7. A sampling pump 9 is fixedly mounted on the upper surface of the mounting plate 6 by bolts. A sample inlet pipe 10 is fixedly connected to the input end of the sampling pump 9. A sample delivery pipe 11 is fixedly connected to the output end of the sampling pump 9. When the motor 4 is started, its output end drives the lead screw 5 to rotate. Since the mounting plate 6 is threadedly connected to the lead screw 5 and the mounting plate 6 is slidably connected inside the vertical trough frame 2, the rotation of the lead screw 5 will cause the mounting plate 6 to descend along the vertical trough frame 2. When the mounting plate 6 reaches the appropriate height, the sampling pump 9 starts, and the sampling tube 10 takes a sample of the grain under the drive of the sampling pump 9. Then, the sample is sent into the turntable mechanism 8 through the sample delivery tube 11.
[0029] The turntable mechanism 8 includes a base 801. A second motor 802 is mounted on the upper surface of the base 801. A movable disk 803 is fixedly connected to the output end of the second motor 802. A circular groove 804 is formed on the upper surface of the base 801. A sliding rod 805 is fixedly connected to the lower surface of the movable disk 803. Several sample storage cylinders 806 are fixedly connected to the upper surface of the movable disk 803. When the second motor 802 is started, its output end drives the movable disk 803 to rotate. The sliding rod 805 on the lower surface of the movable disk 803 slides within the circular groove 804 on the upper surface of the base 801, ensuring the stable rotation of the movable disk 803. When a sample storage cylinder 806 on the movable disk 803 rotates to below the sample delivery tube 11, the sample delivered by the sample delivery tube 11 enters the sample storage cylinder 806. When a second sampling is performed, the second motor 802 is started again to rotate the movable disk 803, causing the next sample storage cylinder 806 to rotate to below the sample delivery tube 11 to receive the sample, and so on.
[0030] The slide rod 805 is slidably connected inside the circular slide groove 804. When the motor 802 drives the movable disk 803 to rotate, the slide rod 805 slides inside the circular slide groove 804, which restricts the movement trajectory of the movable disk 803 and ensures its stable rotation.
[0031] Mounting plate 6 is slidably connected to the inside of vertical slot frame 2. When motor 4 drives lead screw 5 to rotate, mounting plate 6 moves vertically along vertical slot frame 2 according to the thread movement of lead screw 5.
[0032] A pipe seat 12 is fixedly connected to the outer surface of the injection tube 10, and the pipe seat 12 is fixedly connected to the upper surface of the mounting plate 6.
[0033] Both sides of the outer surface of the vertical slot frame 2 are fixedly connected to the diagonal bracing brackets 13, which are fixedly connected to the upper surface of the support plate 1.
[0034] A position sensor 14 is fixedly connected to the upper surface of motor 802. The position sensor 14 is an Omron E2EX10D1 M1 Z, which can accurately detect the approach of the target object. It is well applicable to detecting the position of the sample storage cylinder 806 in the turntable mechanism 8. When motor 802 drives the movable disk 803 to rotate, the position sensor 14 detects the rotation position of the sample storage cylinder 806. When the sample storage cylinder 806 rotates to the accurate position below the sample delivery tube 11, the position sensor 14 sends a signal to ensure that the sample storage cylinder 806 can accurately receive the sample.
[0035] The implementation principle of an automated grain sampling device in this embodiment is as follows: The operator starts motor 4, and the output end of motor 4 drives the lead screw 5 to rotate. Since the mounting plate 6 is threadedly connected to the lead screw 5 and the mounting plate 6 is slidably connected inside the vertical trough frame 2, the rotation of the lead screw 5 will cause the mounting plate 6 to descend along the vertical trough frame 2. The operator determines that the mounting plate 6 has reached the appropriate sampling height by observing the device or according to the pre-set marks. When the mounting plate 6 reaches the appropriate height, the operator starts the sampling pump 9. After the sampling pump 9 is started, the sampling tube 10 connected to its input end samples the grain under the drive of the sampling pump 9. Then, the sample is sent into the turntable mechanism 8 through the sample delivery tube 11. In the turntable mechanism 8, motor 802 is started, and its output... The output end drives the movable disk 803 to rotate. The slide bar 805 on the lower surface of the movable disk 803 slides in the circular slide groove 804 on the upper surface of the chassis 801 to ensure the stable rotation of the movable disk 803. The position sensor 14 detects the rotation position of the sample storage cylinder 806. When the sample storage cylinder 806 rotates to the accurate position below the sample delivery tube 11, the position sensor 14 sends a signal to ensure that the sample storage cylinder 806 can accurately receive the sample. When a second sampling is required, the operator starts the motor 802 again to rotate the movable disk 803, so that the next sample storage cylinder 806 rotates to the position below the sample delivery tube 11. Then, the sampling pump 9 is started to perform a second sampling. The new sample enters the next sample storage cylinder 806, and so on. Multiple sampling operations can be performed as needed.
[0036] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
