However, the present invention may be implemented in many different forms and is not limited to the embodiments described herein. And in order to clearly explain the present invention in the drawings, parts irrelevant to the description are omitted, and similar reference numerals are attached to similar parts throughout the specification.

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

Referring to FIG. 1, according to one embodiment, in the corn harvesting device 1 for measuring the weight and quantity of harvested corn, a de-wilding unit 40 for separating the harvested corn and stalks, and a lower de-wilding unit 40 A transfer unit 10 that is positioned and transports falling objects including corn that has fallen from the wilting unit 40, and an impact sensor 12 installed in the transfer unit 10 to detect an impact of falling to the upper portion of the falling objects transfer unit 10 And it shows the collection unit 20 for collecting the corn transferred from the transfer unit 10.

The wiping unit 40 is a device for degassing the stems connected to corn only with corn. In one embodiment, as the corn stalks are transported together with the corn into the corn harvesting device 1, a part of the corn stalks is introduced between two cylinders, At the same time, the corn connected to it is located under the two cylinders, and the device for transporting the corn stalks and the two cylinders are gradually separated in the direction of travel, so that the corn is caught in the two cylinders and detached. The distance between the two cylinders should be longer than the corn stalk and shorter than the corn width.

The conveying unit 10 is a device for receiving the corn that has been removed from the corn stalk as it falls and transferring it to the collecting unit 20 that collects the harvested corn to take it outside. As it is spaced apart from the transfer unit 10 at a predetermined interval, it is formed so that the corn applies an impact to the transfer unit 10 when peeling.

Referring to FIGS. 1 and 2, the conveying part 10 is formed with a first conveyor belt 11, one end of which is extended from the first conveyor belt 11 to have a predetermined inclination, on which objects fall from the overhanging part 40, The second conveyor belt 13 having the other end connected to the collecting unit 20 and the first conveyor belt 11 and the second conveyor belt 13 to prevent corn being transported from the second conveyor belt 13 from falling It may include anti-fall protrusions 14 disposed to protrude to the outside at regular intervals. Depending on the size or height of the collecting part 20, the corn inlet part of the collecting part 20 may be at a higher position than the conveying part 10 of the corn collecting device, so the corn inlet part of the collecting part 20 in the conveying part 10 By installing the second conveyor belt 13, it can be transported to a predetermined height. In this process, since the conveyed corn may be separated or fall to the floor, the first conveyor belt 11 and the second conveyor belt 13 protrude to the outside to form an anti-fall protrusion 14. can The fall prevention protrusion 14 may be generally made of the same material as that of the conveyor belt, and may be detachably manufactured as needed. In particular, the fall prevention protrusion 14 is not limited according to a specific embodiment in the case of a material and shape capable of supporting a predetermined number of corn.

The shock sensor 12 is installed on the transfer unit 10 to detect an impact when the corn falls onto the first conveyor belt 11 . The first conveyor belt 11 and the second conveyor belt 13 may form one loop, and a power source (not shown) is formed at both ends of the loop so that the first conveyor belt 11 and the second conveyor belt ( 13) can be driven movably. A belt support 15 is positioned between one loop to support the first conveyor belt 11 so that the corn does not flow even when corn falls from the grain-removing part 40, and the first conveyor belt in the direction of the grain-removing part 40 An impact sensor 12 may be placed between (11) and the belt support 15. That is, as the corn that has fallen to the dewadding unit 40 falls onto the first conveyor belt 11, the impact of the corn is detected through the impact sensor 12 disposed above the belt support 15 to determine the number of corn. can judge The shock sensor 12 may also be configured through a general circuit such as an Arduino sensor, which is not limited according to a specific embodiment.

The gap between the stripping unit 40 and the first conveyor belt 11 is to generate an impact as the corn falls onto the first conveyor belt 11, and the larger the gap, the greater the distance can be measured in the transfer unit 10. The impact value may be large, but if the interval is too large, there is a risk of damage such as damage to falling corn, so it is necessary to adjust it appropriately in advance through experiments. This should be adjusted to the extent of distinguishing between the impact value when corn falls and the impact value when other foreign materials, such as corn stalks, fall.

In addition, a separation prevention device (not shown) such as a screen or a net may be additionally installed on the outer surface of the transfer unit 10 so that the corn does not collide with the first conveyor belt 11 when falling and escape to the outside of the device.

Also, referring to FIG. 1, the collection unit 20 includes a container 21 for collecting corn transferred from the transfer unit 10 and a weighing sensor (load) located under the container 21 to measure the weight of the corn transferred. cell) (22). In the case of the container 21, a plastic basket that can be easily transported by a worker as a space for storing a certain amount of corn, a tonbag that can be moved with heavy equipment by hanging a line formed on the top, and can accommodate a large amount of corn, or A pallet, etc. is installed at the bottom, so it can be used as a storage box that can be transported by a forklift. The type of weight measurement sensor 22 is not limited according to a specific embodiment, such as an electronic scale or an Arduino. In addition, after installing the weighing sensor 22 under the container 21, it is possible to measure only the weight of harvested corn by setting the initial weight value to 0.

The control unit 30 sets a predetermined impact value as a threshold value in order to count the number of corns based on the impact value measured by the impact sensor 12, and the impact value measured by falling objects is If it is above the threshold, it can be counted as the number of corn.

When corn is harvested with the corn harvesting device 1, not only corn but also corn stalks, leaves, and other foreign substances are easily introduced, and the corn and corn stalks are not separated by the dewaving part 40 or the separated foreign substances When included in (10) and transported, it is difficult to determine the weight of pure corn only with the weight value measured in the collection unit 20. In order to discriminate only corn from falling objects containing corn and other foreign substances, a threshold value, which is the minimum impact value measured by the impact sensor 12, is set, and when the impact value measured by the falling object is greater than or equal to the threshold value, this is determined. It can be judged by corn. In general, other foreign substances cut by the blade and introduced into the corn harvesting device 1 generally weigh less than the weight of corn, so this method has the advantage of being very easy to determine the number of corn.

In the case of the threshold value, it is possible to set the average weight of each corn according to the variety by calculating the impact value generated when falling from the set height of the transfer unit 10 from the de-wilding unit 40 and giving a slight error value. In the case of an error value, it may be changed in a step of adjusting a threshold value to be described later.

In addition, when the impact value is measured as a predetermined multiple value based on the threshold value, it is determined that one or more corn kernels have fallen at the same time, and this can be reflected in the quantity of corn.

In addition, referring to FIG. 4 , the control unit 30 compares the first measurement value obtained by multiplying the number of corns counted by the weight of each corn and the second measurement value measured through the weighing sensor 22 to obtain a threshold value. can be adjusted. The weight of each corn can use the average weight of corn according to the variety. This is not only the value preset in the control unit 30, but also the database unit 70 where the average weight value of corn according to the variety of corn is stored as data and the input unit 60 through which the user can input the variety of corn currently being harvested. ), the average weight of corn according to the input corn variety can be changed to the weight of each corn and substituted. The number of corns can be determined by comparing the first measurement value calculated as a result with the second measurement value, which is the weight of the whole corn measured through the weighing sensor 22 of the collecting unit 20. That is, when the second measurement value is greater than the first measurement value, the number of corns is less than the actual measured weight of corn, so the shock is detected by the shock sensor 12 by lowering the threshold value, but the number of corns You can increase the number of unrecognized corn. On the other hand, if the second measured value is smaller than the first measured value, since the number of corns measured is greater than the actual measured weight of corn, the threshold value is increased and recognized as the number of corns caused by the impact of foreign substances other than corn. number can be reduced. By adjusting the threshold value in this way, it is possible to derive a quantity close to the actual corn quantity.

Also, referring to FIG. 4 , according to an embodiment, a display unit 50 may be included to display the number of corns counted by the control unit 30 . When the worker needs to carry out the container 21 by determining the quantity of corn in real time as needed, the display unit 50 to show the current quantity of corn may be formed.

In addition, referring to FIGS. 1 and 3, the control unit 30 generates a signal to take out the container 21 of the collection unit 20 when the number of counted corn reaches the set number of corn, and the control unit ( 30) may include a hydraulic unit 80 that adjusts to separate the container 21 from the collection unit 20 and take it out. When the target number of corn is reached in the container 21 of the collection unit 20 through the display unit 50, the operation may be stopped and taken out. However, for automation of the operation, the number of corns is preset When the corresponding value is reached through the control unit 30, the container 21 may be automatically taken out by the action of the hydraulic unit 80. In addition, the control unit 30 generates a signal to take out the container 21 of the collection unit 20 when the second measurement value measured through the weighing sensor 22 reaches the set weight of corn, and the control unit 30) may include a hydraulic unit that adjusts to separate the container 21 from the collection unit 20 and take it out. In this case, since work continuity and separate manpower are not required, work efficiency can be increased.

The hydraulic unit 80 is configured to operate the hydraulic pump 81 with power generated from a power source (not shown) and transport the container 21 to the outside by the movement of the gear 82 connected thereto. Since the performance or specifications of the hydraulic pump differ depending on the type and size of the container, it is not limited according to the specific embodiment.

The corn harvesting device described above and shown in the drawings is only one embodiment for carrying out the present invention, and should not be construed as limiting the technical spirit of the present invention. Improved and changed embodiments without departing from the gist of the present invention will fall within the protection scope of the present invention as long as it is obvious to those skilled in the art to which the present invention belongs.
