Description

  The present invention relates to a panicle threshing device that threshs straw from a pan in a panicle unit.

  Improvement of paddy rice varieties that can maintain high quality against abnormal weather such as a rise in summer temperature in recent years has been demanded, and quality tests are frequently performed with increasing test points. Post-harvest quality surveys are conducted after threshing, mashing and rice selection.

  Rice breeding is mainly carried out by cross breeding, and selection is performed by combining individual selection and line selection. In the individual selection, the crossed seeds are planted one by one in the field in the next year, and excellent strains and ears are selected. In the line selection, one or several seedlings of the same crossing line are planted in the selection process of breeding lines that have passed several generations after crossing, and the lines and spikes with excellent growth characteristics are selected.

  On the other hand, in the yield survey conducted in research on cultivation of rice and soil and soil fertilizer, so-called plow cutting is carried out to cut a certain area (about 3 square meters = about 1 tsubos). In the yield survey, the number of straw per square meter related to ripening, quality and protein content is investigated. In calculating the number of pods per square meter, an investigation may be made to harvest representative stocks separately from the above-described plow cutting. In this case, several stocks that are close to the average number of ears are cut and the number of pods is measured. In this case, the number of pods per square meter is obtained by the product of the number of spikes and the number of spikelets, so it is necessary to measure the number of pods by threshing every spike.

  In addition, as an investigation of harvested rice, there are cases where it is desired to know the cadmium content and quality of brown rice in a field. In such a case, it is normal to perform pruning from 3 to 5 places in the field, but as another method, there is a method of obtaining 100 to 200 long ears from the entire field and obtaining it. In this case, in order to know the relationship with the soil component at the location where the collected ears are planted, it is necessary to obtain a measurement value from the brown rice of the threshed for each ear.

  As mentioned above, rice quality surveys are conducted after threshing after harvesting, rice bran, and rice selection, and rice grinding and rice selection can be easily conducted even with a small amount of sample material to be investigated. For threshing, small samples such as one ear had to be relied on manually, and it was difficult to cope with this.

  In the individual selection and line selection in the above-mentioned rice breeding breeding, the culm is threshed from the selected ear, and quality is determined using brown rice. At this time, conventional machines such as small threshing machines are used for threshing a large amount of selected materials, but in the case of small samples such as `` cutting ears '', there is no place to hold by hand when applying to the machine. Threshing has been done, and there was a problem that sampling of efficient straw was not possible. In addition, when threshing by ear is performed manually, different spikelets may be mixed, and there is a concern that accuracy may deteriorate due to mixing different varieties.

  In yield surveys, a small threshing machine is generally used to calculate the number of pods per square meter in pruning. However, mechanical threshing involves a lot of dust such as dead leaves and branch bellflowers in the sample mash after threshing. There was a problem that it took time to remove. There are some sample rice cakes that contain (fine) rice cakes and those that do not contain (shina) rice cakes, and it is necessary to include fresh rice cakes in the number of spikelets measured during the yield survey. There was a problem that dust could not be removed by wind selection, and soot and dust had to be sorted manually.

  This invention makes it an example of a subject to cope with such a problem. In other words, it is possible to efficiently thresh the sample pods from the ears, to prevent the mixing of different pods in the sample when obtaining the sample pods in one spike unit, including the new pods It is an object of the present invention that a sample soot can be obtained without selecting soot and dust when determining the number of spikelets.

  In order to achieve such an object, a panicle threshing apparatus according to the present invention comprises at least the following configuration.

  A concave lower plate, an upper lid provided with an outer peripheral edge that overlaps with an outer peripheral edge of the lower plate, and a connecting part that connects the upper lid so as to be openable and closable with respect to the lower plate. The outer peripheral edge portion of the lower plate body and the upper lid body serves as a scraping portion that disposes the eyelids from the ear that has placed the collar portion in the lower dish body and has taken the cob out through the outer peripheral edge portion. Ichiho Thresher characterized by.

  According to the panicle threshing device having such a feature, the ears with ridges are sandwiched between the lower plate body and the upper lid body, and the heel portion is arranged in the lower plate body, so that the outer portion of the lower plate body and the upper lid body that overlap each other is placed. The cob is placed outside through the periphery. In this state, by pulling the cob arranged outside while pressing the outer peripheral edge of the upper lid against the outer peripheral edge of the lower plate body, the wrinkles are removed from the ear by the outer peripheral edge of the lower plate body and the upper cover body. The cocoons removed from the ears are stored in the lower plate container.

  By using such a panicle threshing machine, threshing can be performed easily and efficiently in units of panicle. Since the sample basket threshed from one ear is stored in the container of the lower dish as it is, other sample baskets threshed from different ears are not mixed. In addition, since threshing is performed with the upper lid on the lower plate, it is possible to prevent dust from entering the threshed sample bowl, and to obtain a sample bowl without sorting the bowl and dust. Can do.
