Description

Technical Field

[0001] This utility model relates to the field of grain inspection technology, specifically a fully automatic grain inspection device. Background Technology

[0002] Currently, most grain storage enterprises still collect samples for testing manually during the acquisition process, and manually test core indicators such as moisture content, mold, broken grain ratio, and impurity content of the grain.

[0003] For large-scale grain purchasing companies, this manual operation mode has obvious limitations. On the one hand, companies need to invest a lot of manpower to complete sample collection and indicator testing, which increases their operational burden; on the other hand, manual testing is easily affected by subjective experience and operating procedures, resulting in large fluctuations in quality inspection results, making it difficult to guarantee accuracy and consistency.

[0004] This not only affects the efficiency of raw grain procurement, but may also affect the quality of procurement due to deviations in indicator judgment, bringing potential risks to enterprises in subsequent storage, processing and sales, and adversely affecting normal procurement work. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide a fully automatic grain inspection device.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: A fully automatic grain inspection device includes, from top to bottom, a sample divider, a feeder, a sorting mechanism, a weighing mechanism, and a sieving mechanism. The material channel of the sieving mechanism is connected to a thawing mechanism, and the thawing mechanism is connected to a moisture inspection mechanism.

[0007] This invention enables automated feeding, sorting, and testing, saving labor costs and providing more accurate test results.

[0008] The sampler used is a binary divider.

[0009] The feeder and sorting mechanism are each provided in two sets, and the weighing mechanism is provided in four sets. The sample divider can divide the grain into two parts, and simultaneously sort and weigh them, thereby improving the detection efficiency.

[0010] The input end of the feeder is connected to the material distribution channel of the sampler, the output end of the feeder is connected to the material supply channel, the output end of the material supply channel is connected to the input end of the sorting mechanism, one set of material discharge channels of the sorting mechanism is correspondingly set above the first set of weighing mechanisms, the other set of material discharge channels of the sorting mechanism is correspondingly set above the second set of weighing mechanisms, a collection hopper is set below the output end of the second set of weighing mechanisms, and a screening mechanism is set below the collection hopper.

[0011] The sorting mechanism includes an annular channel, a turntable at the bottom of the annular channel, a vision inspection mechanism at the top of the annular channel, and several feeding channels on the side of the annular channel. Each feeding channel has a corresponding nozzle at its top. The vision inspection mechanism is electrically connected to the control system, and the control system is electrically connected to the nozzle.

[0012] The sorting mechanism is mainly used to remove adjacent impurities. The annular channel is narrow, allowing only one grain to pass through at a time. Therefore, the grains line up in the annular channel, and the turntable drives the grains to move. During the movement, the vision inspection mechanism takes pictures of the grains and sends them back to the control system for judgment. If it is qualified grain, the nozzles at the top of the qualified grain feeding channel spray air to blow the grains into the qualified grain feeding channel. If it is adjacent impurity, it continues to move forward until it reaches the adjacent impurity feeding channel, where the corresponding nozzles blow it into the adjacent impurity feeding channel, thus separating the adjacent impurities.

[0013] Multiple feeding channels can be set up for qualified grains and adjacent impurities to improve work efficiency. In addition, each feeding channel for qualified grains and adjacent impurities is equipped with a weighing mechanism to weigh the qualified grains and adjacent impurities.

[0014] The visual inspection mechanism includes a camera and a light source.

[0015] The weighing mechanism includes a weighing hopper and a weighing device installed at the bottom of the weighing hopper. A bottom valve is provided at the output end of the weighing hopper. The bottom valve is electrically connected to the control system, which can control its opening and closing.

[0016] The screening mechanism is a rotary vibrating screen, which is used to separate soil particles and gravel particles from the grain and send them into the impurity channel.

[0017] The lower part of the weighing mechanism and the lower part of the impurity channel of the screening mechanism are both equipped with sample recovery devices to collect impurities such as gravel and stones.

[0018] The thawing mechanism includes a housing with an inlet and an outlet. An electric heater and a vibrating feeder are installed inside the housing. Grains fall into one end of the vibrating feeder through the inlet. The vibrating feeder is turned on to spread the grains evenly and then stops. The electric heater heats the grains. After thawing is complete, the vibrating feeder is turned on again to send the grains to the outlet. Finally, the grains fall into the moisture testing mechanism.

[0019] The beneficial effects achieved by this utility model are: This invention significantly reduces labor costs. Through the coordinated operation of components such as the sampler, feeder, and sorting mechanism, it automates the entire process of feeding, sorting, weighing, sieving, and moisture detection of raw grain samples after collection. This replaces the traditional manual operation mode, greatly reducing the manpower input of large-scale grain purchasing enterprises in the quality inspection process, and effectively reducing labor costs and operational burden.

[0020] This invention improves the accuracy and consistency of testing: it adopts a visual inspection mechanism in conjunction with a control system to achieve accurate identification and sorting of impurities, a vibrating screen to accurately separate soil particles, gravel and other impurities, and a thawing mechanism to ensure the stability of the sample state before moisture testing. It avoids interference factors such as subjective experience and differences in operating procedures in manual testing, and significantly improves the accuracy and consistency of quality inspection results.

[0021] This utility model can improve inspection efficiency and ensure the progress of procurement: the sample divider adopts a two-part divider design, with two sets of feeders, sorting mechanisms and four sets of weighing mechanisms to realize the synchronous diversion and detection of raw grain samples; the multiple sets of qualified and impurity discharge channels further improve the sorting efficiency.

[0024] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0025] Example: like Figure 1 , Figure 2As shown, a fully automatic grain inspection device includes, from top to bottom, a sample divider 1, a feeder 3, a sorting mechanism 5, a weighing mechanism, and a sieving mechanism 9. The material channel 10 of the sieving mechanism 9 is connected to a thawing mechanism, and the thawing mechanism is connected to a moisture inspection mechanism 16.

[0026] The sample divider 1 is a binary divider with two material distribution channels 2.

[0027] The feeder 3 can be any existing feeder or delivery device.

[0028] The feeder 3 and the sorting mechanism 5 are each provided with two sets, and the weighing mechanism is provided with four sets. Each set of sorting mechanism 5 is provided with two sets of weighing mechanisms.

[0029] The input end of the feeder 3 is connected to the material distribution channel 2 of the sampler 1, the output end of the feeder 3 is connected to the material supply channel 4, and the output end of the material supply channel 4 is connected to the input end of the sorting mechanism 5.

[0030] like Figure 2 As shown, the sorting mechanism 5 includes an annular channel 51. A turntable 52 is located at the lower part of the annular channel 51, and the turntable 52 is driven to rotate by an existing mechanism (such as a motor). A vision inspection mechanism is located at the upper part of the annular channel 51. Several openings are provided on the side of the annular channel 51, and the openings connect to the feeding channel 56. Each feeding channel 56 has a corresponding nozzle 55 at its upper part. The vision inspection mechanism is electrically connected to the control system 17, and the control system 17 is electrically connected to the nozzle 55. The nozzle 55 includes an air source pipeline and a solenoid valve. The vision inspection mechanism includes a camera 54 and a light source 53.

[0031] The sorting mechanism 5 is mainly used to remove adjacent impurities, especially suitable for larger grains such as corn. The annular channel 51 is narrow, allowing only one grain to pass through at a time. Therefore, the grains line up in the annular channel 51, and the turntable 52 drives the grains to move. During the movement, the vision inspection mechanism takes a picture of the grains and sends it back to the control system 17 for judgment. If it is qualified grain, the nozzle 55 at the top of the qualified grain feeding channel 56 blows air into the qualified grain feeding channel 56. If it is adjacent impurities, it continues to move forward to the adjacent impurities feeding channel 56, where the corresponding nozzle 55 blows it into the adjacent impurities feeding channel 56, thus separating the adjacent impurities. Multiple feeding channels 56 for qualified grains and adjacent impurities can be set to improve work efficiency.

[0032] In addition, both the qualified grain feeding channel 56 and the adjacent impurity feeding channel 56 are equipped with a weighing mechanism to weigh the qualified grain and the adjacent impurities. The adjacent impurity feeding channel 56 is located above the first weighing mechanism, and the qualified grain feeding channel 56 is located above the second weighing mechanism. A collection hopper 8 is located below the output end of the second weighing mechanism, and a screening mechanism 9 is located below the collection hopper 8.

[0033] The working principle of the visual inspection mechanism, control system 17, and nozzle 55 in sorting and feeding impurities in the above structure is similar to the working principle of the impurity sorting machine described in Chinese patent CN223209966U, entitled "An Unmanned Intelligent Inspection Machine for Grain Impurities".

[0034] The weighing mechanism includes a weighing hopper 6 and a weighing device 7 installed at the bottom of the weighing hopper 6. A bottom valve is provided at the output end of the weighing hopper 6. The weighing device 7 and the bottom valve are both electrically connected to the control system 17. After weighing is completed, the weighing device 7 feeds back the data to the control system 17, and the control system 17 controls the bottom valve to open and release the grain.

[0035] The screening mechanism 9 is a rotary vibrating screen, which is used to separate soil particles and gravel particles from the grain and send them into the impurity channel 11.

[0036] The lower part of the weighing mechanism and the lower part of the impurity channel 11 of the screening mechanism 9 are both equipped with sample recovery devices 12, which are used to collect impurities such as gravel and other impurities. The sample recovery device 12 is a container with an open top.

[0037] Currently, moisture meters are mainly used to test the moisture content of grains. However, these meters have temperature requirements for moisture analysis. When the grain temperature is below 0°C, the accuracy of the moisture readings will be affected. Therefore, in winter, the grain temperature needs to be raised to above 10°C to ensure accurate results. Consequently, in Northeast China, where grain is harvested in winter, it is necessary to thaw the grain first.

[0038] This utility model is applicable to grain harvesting in winter. The thawing mechanism includes a housing 13 with an inlet and an outlet. An electric heater 14 and a vibrating feeder 15 are installed inside the housing 13. Grain falls into one end of the vibrating feeder 15 through the inlet. The vibrating feeder 15 starts to spread the grain evenly and then stops. The electric heater 14 is located above the vibrating feeder 15 to heat the grain. After thawing, the vibrating feeder 15 starts again to send the grain to the outlet, and finally, the grain falls into the moisture testing mechanism 16. The thawing mechanism is conventional equipment and will not be described in detail.

[0039] The moisture testing device 16 is a moisture meter based on existing technology.
