[0034]
A potentiometer 79 is pivotally supported on the front upper portion of the frame portion 72, a detection lever 80 of the potentiometer 79 extends obliquely downward on the rear side, a spring 81 is connected to the detection lever 80, and the detection lever 80 is rotated upward on the rear side. The end of the detection lever 80 tends to come into contact with the outer periphery of the mat seedling.
[0035]
Thus, when the winding of the mat seedling is started or when the winding mat seedling has a small diameter, the detection lever 80 of the potentiometer 79 is rotated rearward and upward by the spring 81, and the detection information of the potentiometer 79 is displayed on the control unit (not shown). ). Then, a speed increasing command is issued from the control unit, the main motor 78 rotates at a higher speed, and the traveling speed of the left and right front / rear wheels 4,. .
[0036]
In addition, the winding mat seedling has a large diameter, the detection lever 80 comes into contact with the outer periphery of the winding mat seedling, and the detection lever 80 of the potentiometer 79 is rotated forward and downward against the spring 81, so that the potentiometer 79 Detection information is input to a control unit (not shown). Then, a deceleration command is issued from the control unit, the main motor 78 is decelerated and rotated, and the traveling speed of the left and right front / rear wheels 4,.
[0037]
Some conventional devices manually shift the running speed and leaf fall belt, but when winding the mat seedling, the operator performs winding work with both hands, so the winding work must be stopped during shifting. There was a problem that work efficiency was reduced.
However, in this embodiment, the traveling speed of the seedling winding assist device 1 and the rotation speed of the leaf fall belt are adjusted so that the speed increase adjustment in the first half of the mat seedling winding operation and the deceleration adjustment in the second half are performed by the operator. The take-up operation is automatically performed without interruption, and when the mat seedling of the latter half has a large diameter, it is decelerated and the large-diameter portion of the mat seedling is guided while slowly contacting the left and right winding auxiliary guides 73, 73. A clean winding mat seedling can be obtained while effectively preventing the protrusion to the left and right.
[0038]
Conversely, when the detection lever 80 of the potentiometer 79 rotates rearward and upward, the main motor 78 decelerates and rotates, and the traveling speed of the left and right front and rear wheels 4,. When the speed is adjusted to decelerate and the detection lever 80 rotates forward and downward, the main motor 78 rotates at an increased speed, and the traveling speed of the left and right front / rear wheels 4,. May be adjusted to increase speed. As a result, when the interval between the winding mat seedling wound by the operator and the seedling winding assisting device 1 becomes wide (when the detection lever 80 rotates upward on the rear side), the winding mat seedling is decelerated. And the seedling winding assist device 1 are accelerated (when the detection lever 80 is rotated downward on the front side), so that the seedling winding is performed according to the work efficiency of the operator who winds the mat seedling. The traveling speed of the auxiliary device 1 can be increased and decreased, the distance between the winding mat seedling and the seedling winding auxiliary device 1 can be optimized, and a beautiful winding mat seedling can be obtained.
[0039]
Next, a method for winding the mat seedling by the seedling winding assist device 1 will be described with reference to FIG.
In this embodiment, the seedling winding assist device 1 is reciprocated to wind up the mat seedling. That is, in the forward travel of moving the traveling means to the right side, the drive roller 13 is rotated clockwise to rotate the leaf fall belts 15 and 15 in the direction of the arrow so that the leaves of the mat seedlings are fallen down. In the reverse stroke in which the means is moved to the left side, the mat seedlings are wound up while the leaf seedling belts 15 and 15 are rotated in the opposite direction of the arrow while the leaves of the mat seedlings are lying down.
[0040]
In the conventional apparatus, an operator lays down the leaf portion of the mat seedling forward while pressing the mat seedling from one end side to the other end side with a pressure roller, and then the seedling winding assist device 1 is attached to the mat seedling. While moving from the end side toward the one end side, the mat seedlings are wound up while the leaf seedling belts 15 and 15 again fall down the leaves of the mat seedlings. In this method, a preliminary pressing roller is required, the preliminary pressing roller is loaded and unloaded on the bench, and the leaf section is overlaid by the preliminary pressing roller, which takes time and increases labor.
[0041]
However, by doing as described above, the preliminary pressing roller is not required, and the seedling winding assisting device 1 can be reciprocated to easily perform the mat seedling winding operation.
FIG. 10 (2) shows an electric circuit for operating the seedling winding assist device 1, which is composed of a forward / reverse switching switch 82, a forward relay 83, a reverse relay 84, a main motor 78 capable of forward / reverse switching, and the like. Thus, the rotation of the main motor 78 is switched by the switching operation of the forward / reverse switching switch 82, and the forward / backward rotation of the traveling means and the forward / reverse rotation of the leaf fall belts 15, 15 are switched.
[0042]
