Description

  The present invention relates to a traveling type tea leaf plucking machine that transports plucked tea leaves from a plucking device to a tea leaf storage device provided behind while plucking tea leaves while running along a teacup.

  In the traveling type tea leaf plucking machine, the following is disclosed, in which the plucked tea leaves are transported by a rising air current in a transport duct connecting the plucking device and the tea leaf storage device. For example, Patent Document 1, Patent Document 2, and Patent Document 3.

  The one shown in Patent Document 1 blows pressure air from the front of a clipper-type cutting blade from a blower pipe having a number of branch pipes, blows off the picked tea leaves rearward, and has a lower end and an upper end bend in an R surface. It is transported by blowing up in a vertical transport duct. Furthermore, a nozzle for assisting transportation by blowing pressure air in the middle of the transportation duct is also provided.

  As shown in Document 2, similar to Document 1, tea leaves plucked with a clipper-type cutting blade are blown rearward by a front blower pipe and blown upward in a transport duct that is blown upward and transported. The difference from Document 1 is that the lower end of the air duct is not an R-shaped bend, but a blowout port for pressurized air for blowing up. In Document 2, two fans are provided: a fan for supplying pressure air blown from the front of the cutting blade and a fan for blowing pressure air into the transport duct.

  What is shown in Document 3 is not a clipper-type cutting blade as a plucking device, but a rotary blade having a rotation axis in the horizontal direction, and blows out pressure air above and behind the rotary blade, It transports the picked tea leaves.

The mainstream is to blow back tea leaves that have been plucked by blowing out pressure air from a blower pipe having a number of branch pipes from the front of the clipper blade. In the plucking device that is fed backward by the rotating body, the rotating body is configured in parallel to the rotation axis.

  In each of Patent Documents 1 and 2, a blower pipe having a comb-shaped branch pipe in front of a clipper-type cutting blade is provided. In this case, if the buds of the tea leaves to be plucked are long or the tea leaves are dense, they will hit the comb-shaped branch pipe before hitting the cutting blade and remain on the surface of the tea tree without being hit by the cutting blade. , Mowing may become mottled. Moreover, in the example of patent document 1, since the R bend is required in the lower part of a perpendicular | vertical transport duct, the space of an R bend part is needed between a plucking apparatus and a transport duct, and a body dimension becomes large. Since the direction of the pressure air changes in the R bend portion, the air blown from the blower branch pipe must be strengthened, and the fan needs to be strong and large. On the other hand, since the thing shown in patent document 2 sends another pressure wind from the downward | lower direction of a perpendicular | vertical transport duct, and blows away tea leaves upward, it requires two fans. Further, the pressure air blown from the lower end of the transport duct drops 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 an air pressure on the entire width of the plucking device on average. In addition, since the duct descends on the side, the duct protrudes sideways from the airframe and interferes with traveling. Patent Documents 1 and 2 both require a large engine and a large plucking machine body.

  In order to send tea leaves plucked with a rotary blade to a transport duct, the one shown in Patent Document 3 is provided with a special outlet for pressure air on the upper rear side of the rotary blade, and the structure is complicated. I need two fans.

  An object of the present invention is to provide a device that prevents the size of the traveling tea leaf plucking machine body from becoming large and the device from becoming complicated, and efficiently transports the picked tea leaves from the plucking device to the tea leaf storage device.

  The first means of the present invention is a gate-shaped frame body provided with a traveling device that travels along a teacup across a teacup with a traveling-type tea leaf plucking machine, and a clipper-type cutting blade below the gate-shaped frame. In order to send the tea leaves into the transport duct, the tea picking device provided, the tea leaf storage device provided at the rear of the picking device, the substantially vertical transport duct through which the ascending airflow for transporting the tea leaf to the upper part of the tea leaf storage device passes, Rotating in a spiral so that the tip moves from the front of the clipper-type cutting blade to the rear, with at least one point in contact with the cutting blade per transport duct, provided close to the surface of the clipper-type cutting blade It consists of a rotating blade attached to the shaft.

  A 2nd means comprises the rotary blade of a 1st means with a flexible member. A 3rd means provides a some rotary blade in the width direction of the body of the portal frame of the 1st or 2nd means. A 4th means twists the rotary blade of the 1st, 2nd, or 3rd means spirally, and attaches it to a rotating shaft. The fifth means attaches the rotating blades of the first, second or third means by shifting the positions of the adjacent rotating blades and the rotating shaft in the circumferential direction.

  With the plucking device provided with the clipper type cutting blade, the tea leaves that have been cut can be continuously sent to the transport duct by twisting the rotating blades in a spiral shape or shifting the angle. Thereby, tea leaves can be plucked without clogging tea leaves in the transport duct.

  Embodiments will be described with reference to the drawings. FIG. 1 is a front view showing an embodiment of a traveling tea leaf plucking machine provided with a tea leaf transport device of the present invention, FIG. 2 is a side view, FIG. 3 is an enlarged sectional view of the vicinity of a clipper type cutting blade and rotating blades, and FIG. It is a perspective view near a die cutting blade and a rotary blade.

  Two crawler type traveling devices 2 and 3 are connected by a gate frame 4 with a teacup 1 interposed therebetween, and a plucking device 5 is provided under the gate frame 4. A tea leaf storage device 6 is provided behind the plucking device 5. The plucking device 5 and the tea leaf storage device 6 are connected by flexible transport ducts 7 and 8. Fans 9 and 10 are installed on the gate mold 4 and are connected to the plucking device 5 by flexible air ducts 11 and 12. The plucking device is divided into two at the central portion, and the leading ends of the air ducts 11 and 12 are fan-shaped hoods 13 and 14 that are connected to the back surface of the plucking device 5. The upper ends of the transport ducts 7 and 8 are hoods 15 and 16 whose bottom surfaces are opened, and are installed on the upper part of the tea leaf storage device 6. The lower ends of the transport ducts 7, 8 are fan-shaped hoods 19, 20 and are connected to the upper part of the plucking device 5. A plurality of tea bags 17 are set in the tea leaf storage device 6 with the upper surface opened. The tea leaf storage device 6 rotates around a support column 18 so that all tea bags 17 in which tea leaves falling from the hoods 15 and 16 are set can be received.

  Reference numeral 21 denotes a clipper-type cutting blade, which has a structure in which two saw blades on the upper and lower sides reciprocate horizontally to cut tea leaves. On the cutting blade 21, a rotating blade 23 that rotates about the rotation shaft 22 is provided at a position close to the surface of the cutting blade 21, and the rotation of moving the tip of the rotating blade 23 from the front to the rear of the cutting blade 21. Rotating in direction. Reference numeral 25 denotes a bottom plate provided along the tip of the rotating body, which faces the blowout port 26 for the pressurized air. The tip hoods 13, 14 of the air ducts 11, 12 change the direction by 180 ° at the lower ends, become the air outlets 26, and are connected to the bottom plate 25.

  Next, plucking work will be described. The plucking device 5 can be moved up and down by hydraulic drive. The traveling devices 2 and 3 are set in the furrows, the plucking device 5 is moved up and down, the cutting blade 21 is aligned with the plucking surface, the cutting blade 21 is driven, and the rotary blade 23 is rotated. Next, when the blower fans 9 and 10 are driven, pressurized air is generated and blows up through the blower ducts 11 and 12 from the outlet 26 to the transport ducts 7 and 8. Next, the tea leaf storage device 6 is slowly rotated. When the machine body is run along the teacup 1, it is cut by the cutting blade 21. The cut tea leaves are sent to the outlet 26 along the bottom plate 25 by the rotary blade 23. At the outlet 26, it is blown upward by the pressure wind blown from below, passes through the hoods 19, 20, rises in the transport ducts 7, 8, falls at the hoods 15, 16, and rotates. The tea bag 17 is accommodated.

  The rotary blade 23 of this embodiment is attached to the rotary shaft 22 by twisting the rotary blade 23 itself in a spiral shape. The width direction of the portal frame 4 is divided into four sections, and two rotating blades 23 twisted by 90 degrees are attached to one section. This is because two rotating blades 23 are provided in two sections for each of the transport ducts 7 and 8 (hoods 19 and 20), so that at least one of the four sheets in total for one transport duct (hood) is the cutting blade 21. It becomes 90 degrees to divide 360 degrees by 4 sheets. In this way, the area through which tea leaves and air pass is always constant. Since at least one place only needs to contact the cutting blade 21, the twisting angle may be increased so as to contact more frequently.

  As another example, as shown in FIG. 5, when four rotating blades 31 are attached to the rotating shaft 22, one rotating blade 23 is twisted 90 degrees. In order to keep the area through which the tea leaves and air pass through always constant, four sheets are set to 360 degrees. At this time, when one transport duct (hood) is divided into two sections, the number of the rotary blades 31 is eight, and thus the single rotary blade 31 may be twisted 45 degrees. When one transport duct (hood) is divided into three sections, the number is 12, so one rotary blade 31 may be twisted 30 degrees.

  As another embodiment, as shown in FIG. 6, it is possible to attach three rotary blades 32 to the rotary shaft 22 in one section. The rotary blades 32 correspond to one transport duct (hood), and the number of the rotary blades 32 is six. When 360 degrees is divided by six, the rotary blades 32 are 60 degrees. . In order to make contact at two places, if 360 degrees is divided by three sheets, it becomes 120 degrees, so one rotary blade 32 may be twisted by 120 degrees.

  When one rotating blade is used for one transport duct (hood), one rotating blade can be twisted 360 degrees and attached.

  As shown in FIG. 7, it is the same even if the rotary shaft 22 is divided for each section and a joint portion is provided and connected.

  Further, as another embodiment, as shown in FIG. 8, without attaching the rotating blade 34, the mounting angle to the rotating shaft 22 is shifted by 45 degrees, and each section is divided into four sections and divided into four sections. A rotating blade 34 is attached.

  As described above, by increasing or decreasing the number of sections, the number of rotating blades in one section, and the angle of attachment to the rotating shaft 22, at least one place may be in contact with the cutting blade for one transport duct.

  The material of the rotary blade is a flexible member such as a brush, cloth, or resin.

  In the present embodiment, the tea leaf container 17 is provided with the tea bag 17, but it may be of a container type.
