Description

Technical Field

[0001] The utility model relates to the technical field of automatic seed counting and weighing, in particular to a thousand-grain weight tester for grains. Background Technique

[0002] The thousand-grain weight of grains is an important parameter in crop variety breeding, fertilizer application and management decision-making. During the growth process of plants, the size of seeds is affected by many factors, such as climate, soil, irrigation, fertilization, etc. Therefore, by measuring the thousand-grain weight of grains, the influence of these factors on the development of crop seeds can be understood, so as to guide reasonable farming management. The thousand-grain weights of different types of grains are also different. For example, the thousand-grain weight of wheat is usually between 30 and 50 grams, while that of corn is between 200 and 400 grams. The detection of the thousand-grain weight of grains is to accurately measure the size and yield of grain seeds, generally through the following steps: sampling, counting, weighing, and repeating multiple times.

[0003] The invention with the authorization announcement number CN105403300B discloses a thousand-grain weight tester for seeds based on machine vision. In this invention, the feeding mechanism feeds the seeds onto the vibrating material spreading mechanism, the vibrating motor makes the seeds spread out flat, the shadowless light source mechanism and the CCD camera mechanism cooperate to count the seeds, and the precision electronic scale weighs the seeds. After being calculated by the computer, the thousand-grain weight of the seeds is obtained.

[0004] The above device can achieve the detection of the thousand-grain weight of seeds. However, when only relying on vision to count the seeds, when there are more seeds, it is easy to cause overlap, resulting in counting errors and also errors in the measured value of the thousand-grain weight. Therefore, a measuring device with accurate counting and reliable measurement is needed. Content of the Utility Model

[0005] The purpose of the utility model is to provide a thousand-grain weight tester for grains to solve the problems put forward in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] A grain thousand-grain weight tester comprises a vibration fixing seat, a vibrator is arranged above the vibration fixing seat, a feed plate is arranged above the vibrator, a storage hopper is arranged above the left side of the feed plate, a feed pipe is arranged at the discharge port below the storage hopper, a material sensor is arranged at the top of the feed pipe and passes through the side wall of the feed pipe, a drive motor is arranged below the material sensor and the drive motor is fixedly connected to the feed pipe, the output shaft of the drive motor passes through the side wall of the feed pipe and extends to the inner side of the feed pipe, a material leveling wheel is fixedly arranged at the end of the output shaft of the drive motor, a material laser sensor is arranged below the right side of the feed plate, a weighing sensor is arranged at the top right side of the vibration fixing seat, a measuring hopper is arranged on the right side of the weighing sensor and below the material laser sensor, and a discharge pipe is arranged below the measuring hopper.

[0008] As a further solution of the utility model: the feed plate is V-shaped.

[0009] As a further solution of the utility model: a solenoid valve is arranged on the discharge pipe.

[0010] As a further solution of the utility model: a receiving hopper is arranged below the discharge pipe.

[0011] As a further solution of the utility model: a plurality of grooves are evenly arranged on the surface of the material leveling wheel.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0013] 1. The detected grains are stored in the storage hopper, and the material sensor measures the falling grains. When the grains are detected, the driving motor and the vibrator are started, the screed wheel rotates, and the grains gradually fall from the grooves on the screed wheel to the conveyor plate. On the one hand, the screed wheel can prevent a large amount of grains from falling onto the conveyor plate at one time, reducing the possibility of congestion. On the other hand, the grooves on the screed wheel can evenly transport a certain amount of grains to the conveyor plate, making it convenient for the conveyor plate to transport the grains to the next stage, thereby improving the efficiency of the device. At the same time, the conveyor plate is a V-shaped structure. When the vibrator drives the conveyor plate to vibrate, the overlapping grains at the bottom of the conveyor plate are vibrated apart, so that the grains can be discharged from the discharge port of the conveyor plate one by one, reducing the counting error caused by overlapping grains and improving the measurement accuracy of the device.

[0014] 2. The material laser sensor is used to count the grains falling from the discharge port of the feed plate, and the weighing bucket temporarily stores the fallen grains. After the material laser sensor completes counting the grains, the weighing sensor weighs the weighing bucket, and the thousand-grain weight of the grains is obtained through computer calculation. There is no need for manual corresponding detection work, which avoids the test results being easily affected by human factors and improves the timeliness of the test results. The receiving hopper can facilitate repeated measurement of grains to improve the accuracy of detection. Brief Description of the Drawings

During storage, the material sensor 6 measures the falling grains. When the grains are detected, the driving motor 11 and the vibrator 8 are started, and the squaring wheel 5 rotates. The grains gradually fall from the grooves on the squaring wheel 5 to the conveying plate 4. On the one hand, the squaring wheel 5 can prevent a large amount of grains from falling onto the conveying plate 4 at one time, reducing the possibility of congestion. On the other hand, the grooves on the squaring wheel 5 can evenly transport a certain amount of grains to the conveying plate 4, making it convenient for the conveying plate 4 to transport the grains to the next stage, thereby improving the efficiency of the device. At the same time, the conveying plate 4 is a V-shaped structure. When the vibrator 8 drives the conveying plate 4 to vibrate, the overlapping grains at the bottom of the conveying plate 4 are vibrated open, so that the grains can be discharged from the discharge port of the conveying plate 4 one by one, reducing the counting error caused by overlapping grains and improving the accuracy of the device measurement.

[0021] A material laser sensor 3 is arranged at the lower right side of the feed plate 4, a weighing sensor 10 is arranged at the top right side of the vibration fixing seat 9, a weighing hopper 2 is arranged at the right side of the weighing sensor 10 and below the material laser sensor 3, a discharge pipe 12 is arranged below the weighing hopper 2, a solenoid valve 13 is arranged on the discharge pipe 12, and a receiving hopper 1 is arranged below the discharge pipe 12.

After the material laser sensor 3 completes counting of the grains, the weighing sensor 10 weighs the weighing hopper 2, and the thousand-grain weight of the grains is obtained under computer calculation, without the need for manual corresponding detection work, avoiding the detection results being easily affected by human factors, and improving the timeliness of the detection results. The receiving hopper 1 can facilitate repeated measurement of the grains and improve the accuracy of the detection.

[0022] When the device is running, turn on the material laser sensor 3, the material sensor 6 and the weighing sensor 10. Place the grains to be detected in the storage hopper 7. When the material sensor 6 detects the grains, start the drive motor 11 and the vibrator 8, so that the material leveling wheel 5 runs. Under the action of the material leveling wheel 5, the grains are evenly fed to the feeding plate 4. The vibrator 8 drives the feeding plate 4 to vibrate, so that the grains are evenly spread on the feeding plate 4 and then fall into the measuring hopper 2 one by one. The material laser sensor 3 counts the grains. After the counting is completed, the weighing sensor 10 weighs the measuring hopper 2. After being calculated by the computer, the thousand-grain weight of the grains is obtained. Then open the solenoid valve 13, and the grains in the measuring hopper 2 fall into the receiving hopper 1 through the discharge pipe 12.
