[Problems to be solved by the invention]
In each of Patent Documents 1 and 2, a blower tube provided with a comb-shaped branch pipe is provided in front of a clipper-type cutting blade. In this case, if the buds of the tea leaves to be plucked are long or the tea leaves are densely grown, they hit the comb-shaped branch pipe before hitting the cutting blade, and are pushed down and remain on the surface of the tea tree without catching on the cutting blade. In some cases, mowing marks may be mottled. Further, in the example of Patent Literature 1, since the R-bend is required below the vertical transport duct, a space for the R-bend is required between the plucking device and the transport duct, and the body size is increased. Since the method of the pressurized air changes at the R-bend portion, the air blown from the blower branch pipe must be increased, and the fan needs to be strong and large. On the other hand, the apparatus disclosed in Patent Document 2 blows tea leaves upward by sending another pressurized air from below the vertical transport duct, and thus requires two fans. The pressure wind blown up from the lower end of the transport duct descends on the side surface of the plucking device by the duct, and is connected to the side surface of the tapered duct provided in the width direction of the plucking device. For this reason, it is difficult to blow up pressurized air on the entire width of the plucking device on average. In addition, since the duct is descending on the side surface, the duct protrudes sideways from the fuselage, which hinders traveling. In both cases shown in Patent Documents 1 and 2, it is necessary to increase the size of the engine and the size of the plucking machine body.
[0008]
The thing shown in patent document 3 is to provide a blow-off port of a pressure air specially on the upper rear side of the rotary blade in order to send the tea leaves picked by the rotary blade to the transport duct, and the structure is complicated, and You need two fans. SUMMARY OF THE INVENTION It is an object of the present invention to provide an apparatus for transporting a plucked tea leaf from a plucking apparatus to a tea leaf accommodating apparatus while preventing an increase in the size of a traveling-type tea leaf pruning machine body and complexity of the apparatus.
[0009]
[Means for Solving the Problems]
In order to solve the above-mentioned problem, in the means of claim 1, a traveling tea leaf picking machine that plucks tea leaves while traveling along a tea ridge with an airframe of a gate form straddling a tea ridge is provided. A plucking device is provided, a tea container is provided at the rear of the plucking device, and a substantially vertical transport duct is provided at the rear of the plucking device for transporting the pruned tea leaves to an upper part of the tea leaf storing device, and a transport duct through which rising wind passes. The tea leaves picked by a cutting blade are fed into the inside by a rotating body, and the tea leaves fly upward. " By using a rotating body to feed the picked tea leaves to the transport duct behind the picking device, a blower with a comb-shaped branch pipe provided in front of the clipper-type cutting blade to blow the picked tea leaves back. A tube is not required, and a fan for sending pressure air to the blower tube is not required, and only one fan is required. Further, the tea leaves can be pushed down by the comb-shaped blower tube to prevent mottle marks from becoming mottled.
[0010]
According to the second aspect of the present invention, a means is adopted in which the cutting blade is a clipper-type cutting blade and the rotating body is a rotating brush. The tea leaves cut with the clipper-type cutting blade will remain on the upper surface of the cutting blade. Therefore, when the tea leaves are swept into the rear transport duct, the tea leaves can be neatly swept if the rotating body has a brush shape.
[0011]
The means of claim 3 uses a means that "the rotating body is a rotating blade with a cutting blade". As a tea leaf plucking device, there are a clipper-type cutting blade and a device using a rotary blade having a cylindrical rotating body with a cutting blade. In the case of a picking device using a rotary blade, it is not necessary to particularly attach a rotary brush, and if the rotary blade is used as a rotating body, it is possible to sweep the picked tea leaves into the transport duct by the rotary blade as it is.
[0012]
According to the means of claim 4, "the rotating brush is provided at a position where the tip of the brush is close to or in contact with the surface of the clipper-type cutting blade, and the tip of the brush which is in contact with the cutting blade is in a direction moving from the front to the rear of the cutting blade. To rotate. " Tea leaves picked with a clipper-shaped cutting blade remain on the upper surface of the cutting blade. If the tip of the rotating brush rotates in the direction in which it moves backward in contact with the surface of the cutting blade, the tea leaves on the harvested cutting blade can be smoothly swept into the rear transport duct.
[0013]
In the means of claim 5, "the rear end of the semicircular bottom plate provided in contact with the outer periphery of the rotating body is connected to the opening of the transport duct provided substantially vertically, and pressure air is blown upward from below the transport duct. Blow up. " The tea leaves picked and put on the cutting blade are sent backward along the semicircular bottom plate in contact with the outer periphery of the rotating body, and are lifted obliquely upward according to the curved surface of the bottom plate. It is thrown into the opening. If it is put on the pressurized air blown up from the lower end of the transport duct, it can be blown upward through the transport duct and transported to the tea leaf storage device.
[0014]
The means of claim 6 employs a means of "sweeping the rotating brush into the transport duct at an angle in a direction delayed from the rotating direction". If the tip of the rotating brush is at an angle α in the direction delayed from the rotation direction, the action of discharging the tea leaves into the transport duct at the connection with the transport duct becomes strong, and the tea leaves stick back to the rotation of the rotating body and return Can be eliminated.
[0015]
According to a seventh aspect of the present invention, the blowout port for the pressurized air blown up from the bottom of the transport duct is provided over the entire length in the longitudinal direction of the semicircular bottom plate provided in contact with the outer periphery of the rotating body, and the blowout port on the bottom side is provided. A blow duct that spreads in a fan shape from above toward the top, blows down so that pressure air is sent evenly over the entire length in the longitudinal direction of the rotating body, turns 180 ° at the bottom, and blows up inside the transport duct "Means. The pressure wind blowing from the bottom of the transport duct must be of uniform intensity over the entire length of the outlet. If the supply duct for the pressure air is fan-shaped and adjusted to the entire length of the outlet, the pressure air to be supplied can be made to have a uniform strength over the entire length. By blowing down the pressurized air in this manner, turning it 180 ° at its tip and blowing it up from the bottom of the transport duct, the pressurized air supply duct for blowing up can be accommodated in the narrow space of the plucking device.

【The invention's effect】
With a picking device equipped with a clipper-type cutting blade, by providing a rotating body with a brush, there is no need for a blower tube with a comb-shaped branch pipe that blows out pressurized air from the front of the cutting blade. The tea leaves immediately before plucking are not pushed down with a tube so that the plucking surfaces are not made irregular. Further, a fan for sending pressure air to the blower tube is not required. By applying a brush to the rotating body, an action of cleaning the surface of the clipper-type cutting blade is generated, and this portion is prevented from being clogged with tea leaves. In the plucking device provided with the rotary blade, a pressure air blowing duct provided at the upper rear of the rotary blade is not required, and a fan for sending the pressure air to the duct is not required. According to the present invention, only one fan is required to generate the pressure wind, and the pressure wind blown from the lower part of the plucking device is made to have an average intensity, so that the tea leaf transporting device can be accommodated in a narrow space, which is simple. Thus, it was possible to make a device for transporting tea leaves with low power.
