Description

Seeding machine including radish seed sorting and counting device {SEEDER MACHINE INCLUDING DEVICE FOR SORTING AND COUNTING RADISH SEEDS}

The present invention relates to a seeding machine, and more particularly, to a seeding machine capable of selecting good seeds and bad seeds from radish seeds sown through the seeding machine and predicting yield by counting the number of good seeds.

In general, in order to sow small seeds such as radish, a method of sitting in the field using a hoe or a hoe, digging the ground, inserting the seeds, and then covering the soil again has been used.

With the development of automated agricultural machines, the sowing of bulbous plants also depends on automated agricultural machines, but in the case of small-scale farmland or fields, manual seeders are often used for economic reasons due to the high price of automated agricultural machines. Methods are being developed to increase the convenience, durability and economy of these manual seeders.

For example, Korean Patent Registration No. 1765270, Korean Patent Registration No. 1470260, Korean Patent Registration No. 1651724, and Korean Patent Publication No. 2016-0097575 disclose various seeders.

In the case of the sowing season, since the seeds received in the storage (hopper) of the sowing machine are used as they are sowed in the field regardless of the condition of the seeds, in the case of defective seeds, they do not germinate even if they are planted in a normal way. If there are many bad seeds, the seeds do not germinate as much, so it is necessary to select bad seeds and good seeds at the time of sowing, and increase the yield by sowing only good seeds in the field.

In addition, if there are many defective seeds, it is difficult to predict the yield of radish crops harvested in the field no matter how many radish seeds are sown, and in the case of the current sowing season, the number of seeds sown is not counted, so there is no way to know exactly how many seeds have been planted.

An object of the present invention is to provide a seeder equipped with a device for selecting and counting radish seeds capable of counting the number of radish seeds sown so that the yield of crops can be predicted.

In order to solve the above problems, according to one aspect of the present invention, a seeder including a radish excellent seed sorting and counting device is provided. Here, the radish excellent seed sorting and counting device is provided in the form of a seed induction tube for inducing discharged seeds, and the radish excellent seed sorting and counting device includes a radish seed weight measurement sensor provided at the top of the inside of the seed induction pipe; A seed size measurement sensor provided below the seed weight measurement sensor inside the seed induction pipe; and a controller including a good/poor seed determination unit for determining whether the seeds are good or bad in response to detection results from the seed weight measurement sensor and the seed size measurement sensor.

In the above-described aspect, the controller includes a reference value setting unit for specifying a reference weight that is a reference weight for determining whether a seed is good or bad,

The good/poor seed determination unit determines that the seed is a good seed when the weight of the seed measured by the seed weight measurement sensor and the size of the seed measured by the seed size measurement sensor satisfy the reference weight and the reference size range, and determines that the seed is a bad seed when either the weight of the seed measured by the seed weight measurement sensor or the size of the seed measured by the seed size measurement sensor does not satisfy a reference value.

In the above aspect, the controller further includes a counting unit, and the counting unit is configured to count and store the number of good seeds and bad seeds determined by the good/poor seed determination unit.

In addition, in the above-described aspect, the good seed sorting and counting device includes a first discharge port through which good seeds are discharged and a second discharge port through which bad seeds are discharged, and when it is determined that the good seed is a bad seed, it is configured to be discharged through the second discharge port by an air blower motor.

Further, in the above-described aspect, the controller further includes a communication unit, and the counting unit is configured to notify the number of counts of good seeds and counts of bad seeds to a user terminal connected through the communication unit.

According to the present invention, the size and weight of the seeds are measured, and seeding is performed by determining that the seeds are excellent seeds only when both the size and weight of the seeds are greater than or equal to the reference value, while if either one of the size or weight does not meet the reference value, the seeds are judged to be defective and stored in a separator, thereby providing a seeder equipped with a function of sorting and counting excellent seeds capable of sowing only good seeds in a field.

In addition, the present invention can provide a seeder that can contribute to predicting the yield of crops by being configured to count only seeds determined to be good seeds.

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

1 to 3 are views showing an example of a seeder having a function of selecting and counting excellent radish seeds according to an embodiment of the present invention. As shown in FIGS. 1 to 3, the seeder is mounted on the tractor 1 and used, but the cover machine 200 is coupled to one side of the seeder 100 so that the soil cover operation can be performed simultaneously with seeding.

The planter 100 has a main plate 111 and vertically attaches vertical plates 112 at both ends of the main plate 111, but forms main shafts 113 on the lower side of the main plate 111 on the left and right sides, forms a guide frame 114 at the front end of the main plate 111, and forms an upper plate 115 maintaining a predetermined interval on the upper side of the main plate 111. 110, a plurality of guide tubes 121 are passed through and fixed downward to the guide frame 114 of the support unit 110, and a compaction roller 122 pressurizing the ground downward is elastically installed in the lower part of the guide tube 121, and a plurality of pressure rollers 131 are sequentially coupled to the main shaft 113 of the support unit 110 to idle, and the pressure roller 13 The elastic removal rod 133 is coupled to the main shaft 113 between the 1) and the pressure roller 131 so that the elastic removal rod 133 is interlocked, but the pressure removal part 130 is located in the front side of the seed guide pipe 121 in the traveling direction, and the upper plate 115 of the support 110. The supply hopper 141 is installed and the lower part of the supply hopper 141 communicates with the upper part of the guide pipe 121 It consists of a supply unit 140, a control discharge unit 150 for discharging grain by combining a supply port (not shown) on the lower side of the supply hopper 141 of the supply unit 140, and a power transmission unit 160 for applying rotational force to the supply port 152 of the control discharge unit 150 by coupling a circular plate 161 to the center of the main shaft 113 of the support unit 110.

The supply unit 140 combines the vibration tube 142 formed of a spring at the bottom of the supply hopper 141 to communicate with the seed guide tube 121 of the discharge compaction unit 120 at the bottom so that vibration can occur continuously.

Therefore, it is possible to smoothly discharge the grains of seeds discharged through the seeder, and at the same time, when a foreign substance is caught, it is possible to easily remove it by opening the spring.

The control discharge unit 150 forms a control chamber 151 communicating up and down with the outlet of the supply hopper 141 of the supply unit 140, and rotates by combining the supply port 152 having the groove 153 formed on the inlet side of the control chamber 151 with the key shaft 154. Grains such as barley seeds of (141) can be accurately discharged one by one to the lower part.

Seeds supplied through the regulated discharge unit 150 reach the seed guide tube 121 through the supply vibration tube 142, and the seeds that reach the seed guide tube 121 are sorted and counted by a seed sorting and counting device installed in the guide tube.

In the case of seeds that meet the specifications in terms of size and weight, they are sown on farmland through the discharge port at the bottom of the guide pipe, but otherwise, that is, in the case of defective seeds, they are collected in the seed collection box 129 disposed on the side of the seed guide pipe.

4 is a view showing an example of an apparatus 300 for sorting and counting good seeds provided to a seeder according to an embodiment of the present invention. As shown in FIG. 4 , the device 300 for sorting and counting excellent radish seeds is installed in the form of a seed guide tube 121 through which seeds are discharged or inside the seed guide tube.

The apparatus 300 for sorting and counting excellent radish seeds includes a pressure measuring sensor 310, a seed size measuring sensor 320, and a seed counting sensor 330 as shown in FIG. 4 .

The pressure measuring sensor 310 functions to detect the amount of impact caused by the seeds falling from the top of the good seeds sorting and counting device 300, that is, from the supply vibrating tube 142. In the case of superior seeds, they have a weight greater than or equal to a pre-determined standard amount.

Since the height H at which the seeds fall is determined almost constantly, the amount of impact generated when the seeds hit the pressure measuring sensor 310 increases or decreases in proportion to the weight of the seeds.

Therefore, when the impact amount measured by the pressure measurement sensor 310 is equal to or less than a predetermined reference value, it may be determined that the seed is a defective seed that is underweight, and when the impact amount measured by the pressure measurement sensor 310 is greater than or equal to a predetermined reference value, it may be determined that the seed is a good seed that satisfies the weight condition.

The reference weight value for seeds is different depending on the type of seeds and can be changed in the controller 350 provided in the sorting and counting device 300 for good seeds.

As shown in the drawing, one end of the pressure measuring sensor 310 is rotatably installed in the guide tube 121, so that when a seed collides with it, its one end is rotated and the seed continues toward the first discharge port 129a.

Seeds whose weight is measured by the pressure measuring sensor 310 then pass through the size measuring sensor 320 installed in the guide tube 121 . Size measurement sensor 320 includes a plurality of laser sensor groups as shown.

Each laser sensor of the laser sensor group includes a laser light emitting unit 320a and a laser light receiving unit 320b, and the laser light emitting unit 320a irradiates the laser light receiving unit 320b with a laser. When the seed passes through the laser light emitting unit 320a and the laser light receiving unit 320b, laser reception is cut off by the seed.

5 is a view for explaining the measurement of seed size using a laser sensor group and the selection of good and bad seeds according to the seed size. In FIG. 5 , the laser light emitting part 320a and the laser light receiving part 320b are arranged at equal intervals from other laser light emitting parts and laser light receiving parts.

For example, considering that seedlings are usually 3.04 × 2.11 × 3.7 mm (L × W × H) and 16.65 g (weight of 1,000 grains), each laser emitting part can be formed at a distance of 3 mm from each other, and when three laser sensor groups are installed, a maximum size of 6 mm can be measured. In this case, radish seeds with a size of less than 3 mm and larger than 6 mm may be considered defective.

Unlike this, the first light-emitting unit and light-receiving unit and the second light-emitting unit and light-receiving unit may be separated from each other by 4 mm, and the second light-emitting unit and light-receiving unit and the third light-emitting unit and light-receiving unit may be separated by 1 mm from the upper side. In this case, seeds less than 4 mm and larger than 5 mm may be considered defective.

This configuration is made in consideration of the average size of radish seeds, because the average size of radish seeds has a round shape with a size of 4 mm × 4 mm. For example, the first and second light receivers and light emitting units from the insertion direction are used to measure the size of radish seeds having a normal size, and the third light receiving unit and light emitting unit are used to measure radish seeds having an abnormally large size.

The embodiment of FIG. 5 shows an example in which each of the laser light emitting unit and the light receiving unit are formed at intervals of 3 mm from each other.

As shown in (a) of FIG. 5, normal radish seeds have an average size of about 4 mm. Therefore, in the case of a good seed having an average size, it should be measured simultaneously between the first and second laser light emitting parts 320a and the laser light receiving part 320b provided at 3 mm intervals. Therefore, when measurements are made simultaneously by the top two laser sensors, it can be determined that the seed is an excellent seed.

On the other hand, as shown in (b) of FIG. 5, if the introduced seeds are not measured simultaneously between the two laser light emitting units 320a and the laser receiving unit 320b, the radish seeds do not satisfy the standard value in terms of size. It can be determined as a bad seed.

On the other hand, as shown in (c) of FIG. 5, when the input seeds are simultaneously measured between the three laser light emitting units 320a and the laser receiving unit 320b, the radish seeds exceed the reference value of 6 mm in terms of size. It can be judged as a foreign material other than the radish seed or a bad seed that is another seed.

The embodiment of FIG. 6 shows an example in which the upper two laser emitting parts and the light receiving part are formed at intervals of 4 mm from each other and the last laser emitting part and the light receiving part are formed at an interval of 1 mm from the second laser emitting part and the light receiving part.

As shown in (a) of FIG. 6, normal radish seeds have an average size of 4 mm. Therefore, in the case of a good seed, it should be measured simultaneously between the first and second laser light emitting parts 320a and the laser light receiving part 320b provided at 4 mm intervals. When measurements are made simultaneously by the top two laser sensors, it may be determined that the seed is a superior seed.

On the other hand, as shown in 6 5 (b), if the introduced seeds are not measured simultaneously between the two laser light emitters 320a and laser receivers 320b of No. 1 and No. 2, the radish seeds may be judged as defective seeds that do not satisfy the standard value in terms of size.

On the other hand, as shown in (c) of FIG. 6, when the input seeds are simultaneously measured between the three laser light emitting units 320a and the laser receiving unit 320b, the radish seeds exceed the maximum reference value of 5 mm in terms of size. It can be judged as a foreign material other than the radish seed or a defective seed that is another seed.

As described above, the controller 390 determines whether the seed dropped from the top is good or bad based on the amount and size of the impact measured through the pressure sensor 310 and the size sensor 320.

When the weight of the seed is greater than or equal to the reference value and the size of the seed is greater than or equal to the reference value, the controller 390 counts it as a good seed to be sown. On the other hand, if either the weight of the seed or the size of the seed does not meet the reference value, the controller 390 counts the seed as a defective seed, and at the same time drives the air blower 350 to send the falling defective seed toward the second discharge port 129b, and the defective seed is collected in the seed collection box 129 by compressed air from the air blower 350.

7 is a diagram schematically illustrating an example of the controller 390 described above. As shown in FIG. 6 , the controller 390 of the device 300 for sorting and counting good seeds includes a data collection unit 391, a reference value setting unit 392, a good/bad seed determination unit 393, an air blower driving unit 394, a counting unit 395, and a communication unit 396.

The data collection unit 391 collects detection results from the pressure detection sensor 310 and the size detection sensor 320 installed in the device 300 for sorting and counting good seeds.

From the collected information, the good/poor seed determination unit 393 determines whether the input seeds are good or bad. Determination of good/poor seeds is made based on the standard weight and standard size set in the standard value setting unit 392 .

The good/poor seed determination unit 393 determines that the seed is a good seed if the measured weight (or impact amount) and size of the seed satisfy both of the predetermined weight (impact amount) and size, and determines that the seed is a bad seed if one of them does not meet the reference value.

The reference value setting unit 392 functions to determine the lowest weight of the seed to be measured. The reference weight value of seeds used in the reference value setting unit 392 may be input from a user terminal connected through a wireless or wired communication unit 396 .

The counting unit 395 is configured to count good seeds and bad seeds determined by the good/bad seed determining unit 393 . As described above, good seeds may be counted by measuring the size and weight of the seeds, but as shown in FIG. 4 , a separate counting means 330 may be provided to the first discharge port 129a for counting.

The number of good seeds and bad seeds counted through the counting unit 395 is stored in a memory provided in the controller 390, and the user can view count information on good and bad seeds by connecting the user terminal to the communication unit 396. Count information or ratio information for good and bad seeds may be used to manage seed quality. For example, when a user purchases seeds from multiple vendors, it may help to select a vendor with a high percentage of quality seeds.

When it is determined that the good/bad seed determination unit 393 is a bad seed, the controller drives the air blower motor 350 through the air blower driving unit 394 to the second outlet connected to the seed collection box 129. Discharge the seed in the direction of 129b.

8 is a flow chart showing the control flow in the controller of the apparatus 300 for sorting and counting excellent radish seeds according to the present invention.

As shown in FIG. 8D, the controller of the apparatus 300 for sorting and counting good radish seeds according to the present invention first measures the weight using the seed weight measuring sensor provided at the top of the inside of the seed guide pipe in step S120 when radish seeds are input in step S110. The gravimetry serves to select radish seeds that are above or below the average weight.

Specifically, in step S130, it is determined whether the measured radish seed weight is within the reference range. In step S130, when the weight of the measured radish seeds exceeds the reference range, the step proceeds to step S175 and is determined and counted as defective seeds.

In step S130, if the measured radish seed weight is within the standard range, for example, within ± 15% of the average weight of radish seed, the step proceeds to S140 to measure the size of the radish seed.

The size of the radish seed is performed through steps S150 to S165 as shown in FIG. First, the controller detects whether a disconnection signal (OFF signal) is input from the first laser sensor. If the OFF signal is not input from the first laser sensor, the step returns to S140, and when the first off signal is detected in step S150, the step proceeds to S155.

In step S155, it is detected whether a disconnection signal is input from the second laser sensor. When the OFF signal of the second laser sensor is detected, it is determined whether or not a disconnection signal is simultaneously detected from the first laser sensor. When disconnection signals are simultaneously detected from the first and second laser sensors, the process proceeds to step S165, otherwise, the process proceeds to step S160.

When proceeding to step S165, the controller determines whether disconnection signals (OFF) are simultaneously detected in all laser sensors from No. 1 to No. 3 laser sensors.

On the other hand, if a short circuit signal (on) is detected from the laser sensor 1 at the same time that the disconnection signal is detected from the laser sensor 3 in step S165, the controller determines that the corresponding radish seed satisfies the standard size and proceeds to count as good seeds in step S170.

On the other hand, if an off signal is detected from the second laser sensor in step S160 and an on signal is detected from the first laser sensor, the controller determines that the size of the corresponding radish seed is insufficient and proceeds to step S175 to count as a bad seed.

According to the present invention described above, the size and weight of the seeds are measured, and the size and weight of the seeds are both high -quality seeds when the size and weight of the seeds are more than the reference value, and the sowing is performed, and if either of the size or weight does not meet the reference value, it is determined that it is a defective seed, so that only the best seeds can be sown in the field, and the excellent seeds and the defective seeds are found. By counting the number, it is possible to determine the expected yield, and the advantage of being able to select suppliers who supply good quality seeds can be obtained.
