Description

  The present invention relates to an apparatus for winding a cold koji coated on a tea tree before plucking the tea leaves.

 In the shoots of tea trees, chlorophyll increases by shading during growth, and the leaf color becomes bright green. At the same time, amino acids such as theanine increase and tannin, which is 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 this simple covering material, cold candy is used, and as a coating method, there are a method of making a shelf for covering the cold potato, a method of coating directly on the tea tree, etc., but it is often coated directly on the tea tree. .

  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 that is stretched over the tea tree, and the operator winds up the koji koji by hand as well as when covering it. The wound cold kneads weighed about 15 kilograms and were heavy, requiring one worker on each side of the teacup. And, when the rolled cold straw was placed on the tea tree, the shoots of the tea tree were damaged, and the quality of the tea product after plucking was degraded, so it was necessary to hold the tea tree so that no load was applied on the tea tree . It was very hard work because I had to move around the tea plantation with heavy cold water and repeated this work tens of times throughout the tea plantation.

  Therefore, in recent years, an attempt has been made to mechanize the work of winding up the cold straw, and Patent Documents 1 and 2 have been invented.

  In the past, in the tea garden, the operator picked tea leaves while moving in the tea garden with scissors by hand, but in recent years, the riding type tea leaf plucking machine such as Patent Document 3 or Patent Document 4 Such riding-type tea garden management machines have been invented and are becoming popular.

  In the apparatus as described in Patent Document 1, the winding work is mechanized and the burden on the operator is reduced. However, the wound cold chill is heavy and remains the same as heavy labor. The device as described in Patent Document 2 does not need to have a rolled-up cold water bottle, but becomes a dedicated machine including a work carriage, which increases the introduction cost and requires a storage space.

  The winding diameter of the wound cold roll is about 40 centimeters (depending on the thickness of the cold roll), and the winding diameter is different between the beginning of winding and the completion of winding, and the winding efficiency is different. When the operator winds up as in Patent Document 1, or when the operator moves the carriage or operates the winding as in Patent Document 2, the adjustment can be made artificially. However, if this is mechanized, it must be adjusted.

  This invention makes it a subject to provide the apparatus which winds up the cold koji coated on the tea tree in order to release an operator from heavy labor.

First means estates for cheesecloth winding apparatus of the present invention includes a rotating shaft which is laterally placed to take up the cheesecloth, more configuration and driving means of said rotary shaft, as well as detachable to riding tea plantation work machine Rotate the tension arm pivotally, place it on the cold chill before winding, measure the position of the tension arm, measure the tension of the cold chill before winding, and make the tension constant The rotational speed of the rotary shaft is adjusted . The second means measures the tension arm with a potentiometer in the first means.

  According to the present invention, the worker is freed from the heavy labor of winding up the cold chill placed on the tea tree. Further, according to the second aspect, since the riding tea plantation machine travels at a constant speed, it is possible to safely travel and work according to the topography and farm field conditions. In other words, by measuring the tension of the cold straw with the tension arm, the winding speed of the cold straw is measured, and the winding speed is adjusted by the number of rotations of the rotating shaft, so that the riding tea plantation machine runs at a constant speed. be able to. According to the third aspect, it is possible to accurately measure the tension of the cold straw. According to claim 4, the apparatus of the present invention can also be used to coat a cold chill. According to the fifth aspect, it can be attached to a riding type tea leaf picking machine or riding type tea garden management machine owned by an operator, and can be used for general purposes. Furthermore, if a riding-type tea leaf plucking machine is used, the tea leaf can be plucked as it is after winding the cold koji, which is convenient.

  First, the riding tea leaf picking machine A will be described. The machine body 1 has a gate-like shape straddling the tea tree D, and the machine body 1 is caused to travel with the traveling devices 2 on both sides of the tea tree. The traveling device 2 is driven by a driving source such as the engine 3 and the hydraulic pump 4 to travel. In the present embodiment, a clipper-type cutting blade 5 is provided, and a blower pipe 6 for blowing off the picked tea leaves is provided slightly before this cutting blade 5, and a flexible hose (not required when winding a cold chiller, not shown) ) To send wind from the connected blower 8. A tea bag holding plate 9 for holding a tea bag for storing the picked tea leaves is connected to the rear of the cutting blade 5. An attachment mounting portion 10 is provided at the rear portion of the tea bag holding plate 9. The cutting blade 5, the blower tube 6, the tea bag holding plate 7, and the attachment mounting portion 10 are integrated and can be moved up and down in accordance with the height of the tea tree D. Step 11 is where the operator rides, and the seat 12 is the part where the operator sits. The operator operates the operation unit 13 such as a traveling handle and a cutting blade switch, and the riding type tea leaf plucking machine A is driven while plucking. To do.

  Next, the cold potato winder B for tea garden will be described. The rotating shaft is rotated by a motor 22 that is a driving means 21. The power switch of the motor 22 can be operated remotely. Winding guides 23 are provided at both ends of the rotating shaft 21 so that the cold chill 32 is wound up beautifully. The tension arm 24 is pivotally supported above the rotary shaft 21 so as to be placed on the cold chiller 32 in front of the rotary shaft 21. The position where the tension arm 24 is pivotally supported is the upper side in the present embodiment, but may be the rear side as long as it can measure the tension of the cold chill before the winding. The tension arm 24 is placed on the cold tub 32, and when the cold tub 32 rises, the tension arm 24 is placed on the cold tub 32 so that the tension arm 24 is lifted, and the potentiometer 26 measures how much the tension arm 24 is lifted. To do. When the potentiometer 26 measures that the tension arm 24 is lifted, the rotation speed of the motor 22 is changed to slow down the rotation of the rotary shaft 21.

  The frame 27 on the left side of the cold chiller winder B for the tea garden is used as a door 29 that can be opened and closed by a hinge 28. At the time of winding, the door 29 is closed and fixed with the fixture 30, and when the wound cold tub 32 is removed, the fixing of the fixture 30 is released, the door 29 is opened, and the cold tub 32 is extracted. At this time, the freezer 32 can be pulled out together with the rotating shaft 21. (It is possible to leave only the rotating shaft 21 and remove only the cold chill 32)

  Next, the cold chiller winder B for tea garden is attached to the riding type tea leaf plucking machine A. The frame 27 of the tea chiller winding device B for tea garden is provided with an attachment portion 31, and is attached to the attachment attachment portion 10 of the riding tea leaf plucking machine A. Thereby, it is detachable without a tool.

  The operation | work which winds the cold chill 32 coated on the tea tree D with the above apparatuses is demonstrated. First, one end of the cold tub 32 taken up by the operator is fixed to the rotary shaft 21. Then, the operator sits on the seat 12, turns on the power switch of the motor 22 of the tea garden cold chiller winder B, and causes the riding type tea leaf plucking machine A to run backward. Then, the riding type tea leaf plucking machine A travels backward while winding the cold chiller 32 around the rotating shaft 21 of the cold chiller winding device B for tea garden. As the winding of the cold chill 32 progresses, the winding diameter of the wound cold chill gradually increases, and the winding length of the cold chill 32 per rotation of the rotating shaft 21 becomes long, that is, the winding speed increases. The winding speed becomes faster than the traveling speed of the riding type tea leaf plucking machine A, and the tension of the cold chiller 32 becomes stronger. Furthermore, if the cold chill 32 is pulled strongly, the cold chill 32 will be dragged over the tea tree D. To prevent this, the traveling speed of the riding type tea leaf picking machine A is increased, or a cold chill roll for tea gardens is used. It is necessary to lower the winding speed by lowering the rotational speed of the rotary shaft 21 of the take-up device B.

  In order to increase the traveling speed of the riding type tea leaf picking machine A, it is necessary for the operator to operate, and it is dangerous to gradually increase the traveling speed. Therefore, increasing the traveling speed of the riding type tea leaf picking machine A. Is not preferred. Therefore, when the winding diameter of the cold candy is large and the winding speed of the cold candy is faster than the traveling speed of the riding tea leaf plucking machine A, the tension arm 24 on the cold chiller 32 is The rotation of the portion that is pushed upward and pivotally supports the tension arm 24 is measured by a potentiometer 26, the rotational speed of the rotary shaft 21 of the cold water take-up device B for the tea garden is lowered, and the winding speed is decreased. Decrease the tension. On the other hand, when the winding speed of the cold chiller is slower than the traveling speed of the riding tea leaf plucking machine A and the tension is weak, the tension arm 24 follows the tension (sag) of the cold chiller 32 and the tension arm 24 is lowered. Thus, the tension arm 24 is measured by the potentiometer 26, the number of rotations of the rotary shaft 21 of the tea garden cold chiller winding device B is increased, and the winding speed is increased. By performing this operation, the freezer 32 maintains a constant tension. Therefore, it is possible to perform good winding with the traveling speed of the riding type tea leaf plucking machine A being constant. That is, the rotation speed of the rotating shaft 21 of the cold chiller winding device B for tea garden is adjusted so that the traveling speed of the riding tea leaf plucking machine A and the winding speed of the cold chiller are the same.

  When one sheet of the cold chiller 32 of about 50 meters is wound, the left door 29 of the cold chiller winder B for tea garden is opened, and the cold chiller 32 is removed from the cold chiller winder B for tea garden. Then, it moves to one end of the next cold tub 32 and similarly performs a winding operation.

  When the cold strawberry 32 is coated on the tea tree D, the rolled cold chiller 32 is set on the rotating shaft 21 of the cold chiller winder B for the tea garden, and the riding tea leaf plucking machine A is moved to the tea tree D covering the cold chiller 32. Then, one end of the cold chiller 32 is fixed to the tea tree D, and the riding tea leaf plucking machine A is moved forward. Even if the rotating shaft 21 is not driven by the motor 22, the rotating shaft 21 rotates and the cold chill 32 can be spread and covered on the tea tree D. Similarly to the winding, the cold arm 32 can be covered without sagging by adjusting the number of rotations of the rotary shaft 21 while watching the tension state of the cold shaft 32 by the tension arm 24 at the time of covering.

  By mounting the cold chiller winding device B for tea garden on the riding type tea leaf picking machine A and running the riding type tea leaf picking machine A, the cold chiller 32 can be wound and covered.

  As another embodiment, a riding tea garden management machine C will be described. The machine body 41 has a gate-like shape straddling the tea tree, and the machine body 41 is caused to travel by being provided with traveling devices 42 on both sides of the tea tree. The traveling device 42 is driven by a driving source such as an engine 43 and a hydraulic pump 44 to travel. In step 51, the operator gets on and the seat 52 is a part where the operator sits, and the operator operates the operation unit 53 to run the riding type tea garden management machine C to perform work. The blower 54 is fixed to the machine body 41 because air may be required when performing the work by the attachment, but is not used for the work of the present invention. Therefore, the riding type tea garden management machine C to which the blower 54 is not fixed may be used.

  An attachment mounting portion 48 is provided on the rear portion of the machine body 41 so as to be movable up and down. The attachment mounting portion 48 is moved up and down by an attachment up / down motor (not shown) along the attachment up / down rail 49. In this embodiment, the attachment mounting portion 48 is moved up and down by the attachment up / down motor and the attachment up / down rail 49. However, the mechanism for moving up and down may be another mechanism, and may be moved up and down by the cylinder and the arm.

  Attach the cold chill winding device B for tea garden to the riding type tea garden management machine C. The attachment part 31 provided in the frame of the cold water take-up device B for tea gardens is hooked and attached to the attachment attachment part 48 of the riding type tea garden management machine C. If it does in this way, similarly to the Example attached to riding type tea leaf plucking machine A, the cold chiller 32 can be wound up and coat | covered.
