Grain sorting system

Abstract

The results of the first and second grain classifications for the first and second periods in a given field can be compared from the perspective of the yield difference. [Solution] The grain discrimination system comprises a grain discrimination machine that classifies grains in each field into multiple grain states: damaged rice, discolored grains, immature rice, and whole grains; a state classification unit that classifies the weight or proportion of the multiple grain states for each field over multiple periods for multiple fields; a storage device that stores the grain classification results from the state classification unit separately for each field over the multiple periods; and a display device that displays a comparison screen that shows the first and second grain classification results, which indicate the weight or proportion of the multiple grain states for a predetermined field input into the field input unit during the first and second periods input into the period input unit, for comparison on the comparison screen, which displays the first and second harvest yields for each predetermined field during the first and second periods, and a harvest yield difference value, expressed as negative or non-negative, obtained by subtracting the first harvest yield from the second harvest yield for the same field.

Claims

1. A device for sorting grains grown in a field, for each field, comprising a grain sorter that sorts the input grains into multiple grain states such as damaged rice, discolored grains, immature rice, and whole grains, A condition classification unit takes the grain classification results for each field, determined by the grain sorting machine, and divides each field into multiple grain conditions such as damaged rice, discolored grains, immature rice, and whole grains, and associates the weight or proportion of each grain condition with the other multiple grain conditions. This classification of multiple grain conditions is performed in common for multiple fields over multiple periods. A storage device that stores the grain classification results, in which the multiple grain conditions are classified for each field by the state classification unit, separately for each of the multiple period periods, A display device that displays a comparison screen for comparing multiple grain classification results for a predetermined field with different time periods, among the grain classification results for the multiple fields stored in the storage device, Equipped with, The display device displays a period input section in which multiple periods can be input, and a field input section in which at least one field can be input as the predetermined field, along with multiple grain classification results on the comparison screen. The display device extracts from the storage device the first period and the second period, which are multiple periods input to the period input unit, and the multiple grain classification results that match the predetermined field, which are input to the field input unit, and displays them on the comparison screen. The comparison screen displays, at least, the following grain classification results side by side: a first grain classification result showing the state of the multiple grains and the weight or percentage of each grain state in the predetermined field during the first period; and a second grain classification result showing the state of the multiple grains and the weight or percentage of each grain state in the predetermined field during the second period; the first harvest yield for each predetermined field during the first period is displayed corresponding to the first grain classification result for each predetermined field; the second harvest yield for each predetermined field during the second period is displayed corresponding to the second grain classification result for each predetermined field; and for the same field, the yield difference value, expressed as negative or non-negative, obtained by subtracting the first harvest yield from the second harvest yield is displayed for each predetermined field. The display device is a grain classification system that, when the first period and the second period are input to the period input unit, and at least one or more fields with a negative yield difference value and / or at least one or more fields with a non-negative yield difference value are input to the field input unit, extracts a plurality of grain classification results that match the input fields from the storage device and displays them on the comparison screen.

2. The grain discrimination system according to claim 1, wherein the display device displays the grain discrimination results for a predetermined grain state among the plurality of grain states of the grain classification results classified by the state classification unit on a result display screen including a field map including a field.

3. The system includes a state selection unit that selects a predetermined grain state from the aforementioned plurality of grain states on a setting screen. The display device displays the comparison screen based on the first operation, and displays the results display screen based on the second operation. When the state selection unit selects a detailed setting displayed on the result display screen, it displays the setting screen on the display device, and on the setting screen, it is possible to input one of the following as the predetermined grain state: damaged rice, discolored grains, immature rice, and whole grains. The grain discrimination system according to claim 2, wherein the display device displays the grain discrimination result corresponding to the grain state selected in the state selection unit on the setting screen for each field on the field map on the result display screen.

4. The system includes a range setting unit for setting the range of the grain discrimination result on the setting screen, The grain discrimination system according to claim 3, wherein the display device displays the fields corresponding to the grain discrimination results that fall within the range setting section from the grain discrimination results in a manner that distinguishes them from other fields.
