Description

  The present invention relates to a device for winding a cold strawberry coated on a tea tree before plucking the tea leaves, and more particularly to a cold potato winding shaft provided with a cold strawberry locking mechanism.

  In the shoots of tea plants, chlorophyll increases by shading during growth, the tea leaves turn bright green, amino acids such as theanine increase, and tannin, a bitter taste component, decreases. For this reason, tencha, gyokuro, kabusecha, etc. have been manufactured for a long time, but in recent years, even in the case of general sencha, simple coating (low shading rate, short period) is performed to improve quality. There is an increasing trend. As a simple covering material, cold candy is used, and there are several methods of covering such as making a shelf to cover the cold potato and directly covering the tea tree. There are many.

  The cold chill for tea garden is about 180-230 centimeters wide and about 50 meters long according to the tea bowl. During storage, it is stored in a state where it is wound in a width of about 180 to 230 centimeters, and at the time of covering, the tea tree and the cold potato are fixed at one end of the teacup, and the operator spreads the rolled cold chilled by hand, It was covered on a tea tree. And just before plucking the tea leaves, it is necessary to wind up the cold koji covering the top of the tea tree, and the operator winds up the koji koji manually as in the case of covering. The wound cold kneads weighed about 15 kilograms and were heavy, requiring one worker on each side of the teacup. When the rolled cold straw is placed on the tea tree, the shoots of the tea tree will be damaged, and the quality of the tea leaves after harvesting and the tea product after tea making will deteriorate, so the load will not be applied on the tea tree There was a need to do. It was very hard work because I had to move through the tea garden with heavy cold water and repeated this work dozens of times throughout the tea garden.

  Therefore, in recent years, Patent Documents 1, 2, and 3 have been invented. In order to wind up the cold cake with a driving means such as a motor, it is necessary to temporarily fix one end of the cold cake on the cold reel winding shaft. Therefore, inventions like Patent Documents 1 and 2 have been made. In addition to fixing as in Patent Documents 1 and 2, the cold candy was affixed to the cold potato winding shaft with gum tape or the like, or was fixed with a string.

  In Patent Documents 1 and 2, the structure is complicated, and it is difficult to perform both the operation of locking the chill kite to the chill kit winding shaft and the operation of manufacturing the chill kit winding shaft. Moreover, since the cold iron winding shaft like patent documents 1 and 2 has a part which latches a cold iron at the front-end | tip, it could not be utilized for an apparatus like patent document 3.

  When sticking with gum tape or fixing with string, there is a risk that the gum tape or string will fall into the tea tree, and if the dropped gum tape or string is collected together with the tea leaves when plucking the tea leaves, There was a problem of mixing. Therefore, it was necessary to avoid the use of gummed tape or strings.

  It is an object of the present invention to provide a chill kite locking mechanism of a chill kit winding shaft that can be easily attached to a chill kit winding shaft with a simple structure and can be used in an apparatus such as Patent Document 3. It is said.

A cold chill locking mechanism for a cold rewinder take-up shaft having a protrusion toward the surface. The second means is a shape in which, in the first means, the locking portion fits within a circumference of the cold winder winding shaft.

  The present invention has a simple structure in which only a cold iron winding shaft is processed, and no other components are required, so that it can be manufactured at low cost. Since there are no locking portions at both ends of the cold air winding shaft, the cold air winding shaft can be used either in a cantilever manner or in both ends. When the cold iron winding shaft is reversed, the cold iron can be removed from the protrusion of the locking portion, and the cold iron winding shaft can be removed from the cold iron. As the second means of the present invention, since the protrusion of the locking portion does not protrude from the cold chill winding shaft, it is easy to remove the cold chill from the cold chill winding shaft, and it is not damaged by being caught by the cold chill winding shaft. It is also possible to insert the cold winder shaft again.
