Have been. On the other hand, on the other hand, since such an object has been achieved, there has been a demand for the development of a method capable of further improving the work efficiency of subsequent handling of reaping tea.

[0003] At present, the handling (handling) of reaping tea is premised on relying on humans, and a storage bag of a size such that one unit is about 25 to 30 kg, which can be carried alone by an operator, is used. This is set on the tea machine each time the work is performed, and when it is full, the mouth is closed and the truck is loaded on the truck. On the other hand, even after being transported to a tea factory, the mouth of each of these storage bags is opened so that the reaper can be taken out.

On the other hand, in the present tea reaper, for example, a riding type plucking machine or the like is used for labor saving as described above, and a large amount of plucking is performed at one time. It is becoming incompatible with such labor-saving tea mowers.

Alternatively, a mechanism that moves up and down using a hydraulic cylinder, a mechanism that uses a ball screw mechanism, and a mechanism that uses a link mechanism 73 in the form of a pantograph as schematically shown in FIG.

The apparatus for handling cutted tea in the tea ridge running tea cutter according to the present invention has the above-described specific form, and its use will be described below. (1) Storage of Cutting Tea The cutting tea cut by the tea reaper 3 is fed into the container 6 through the relay transfer device 4 and stored. When the storage capacity is full, the truck T is receded to the side of the loading platform Ta of the truck T as it is. Of course, the bed T of the truck T
Since it is also possible to insert from the back of a, in this case, the riding type tea picking machine 1 is moved to the back of the loading platform Ta.

(2) Position Adjustment of the Loading Position of the Truck on the Loading Bed In order to load the truck T on the loading platform Ta, the position of the container 6 is adjusted. Basically, first, the container 6 is moved up and down
To raise. Then, for example, the riding type tea picking machine 1 is slightly moved, and the container 6 is moved backward to a desired position in the width direction of the bed Ta of the truck T. Thereafter, the height is appropriately adjusted by the elevating mechanism 7, and the container 6 is positioned at a desired charging position. At this time, it is preferable that the container 6 be movable in the elevating direction. However, for example, the transfer operation position to the truck T or the like is fixed, and the riding type tea picking machine 1 is mounted on the platform T of the truck T in a platform shape. When the container 6 is at a higher position, it is not necessary to independently move the container 6 up and down more than moving the container 6 up and down together with the tea mower body 3. Of course, the actual work site does not have such conditions of the loading area, so that the container 6 can be freely raised and lowered to some extent.
In addition, a horizontal moving mechanism may be provided so as to be movable in the horizontal direction so that the container 6 can protrude rearward.

(3) Loading After the loading position is determined, the peripheral frame 6B is slid backward by the peripheral frame horizontal shifting mechanism 6C, and the discharge opening E is opened while pulling and driving the conveying surface of the bottom body 6A. I do. Then, the reaping tea on the transport surface of the bottom body 6A in the container 6 is piled up on the carrier Ta of the truck T from the discharge opening E. When the front end of the peripheral frame body 6B is located at the rear end of the bottom body 6A, all the cutting tea is put in. Incidentally, the peripheral frame body 6B moves rearward in this way, but the bottom body 6A on which the cutting tea is mounted does not move, and the empty peripheral frame body 6B moves.
The center of gravity of the riding-type tea leaf picking machine 1 does not largely move rearward when the cut tea is discharged due to the movement of only the cut tea. When all the cutting tea has been put in, the peripheral frame 6B is returned to its original position, the discharge opening E is closed, and after leaving the truck T, the container 6 is cut to a predetermined position, and cutting is resumed.

Other Embodiments Although the basic embodiment of the present invention is as described above, various other modifications can be made. For example, the one shown in FIG. 5A is a preferred embodiment in which the shape of the peripheral frame 6B is different. That is, in this device, the lower part of the rear end surface (right side in the figure) of the peripheral frame body 6B is formed as a sloping inclined surface 6s, and the lower part of the front end surface (left side in the figure) is also inclined rearward. This is an embodiment formed in 6s. When the peripheral frame body 6B is configured in this manner, a small amount of tea leaves is first taken out, so that the truck T and the riding-type tea leaf picking machine 1 receive less shock at the time of the first feeding, and preferable feeding can be performed. In addition, since the lower part of the front end surface is also the inclined surface 6s, the last tea leaves can be smoothly discharged. In addition, in this specification, the rear end surface of the peripheral frame body 6B is defined as a surface in the direction in which tea leaves are taken out, and the front end surface is defined as a surface opposite thereto. Also, as shown in FIG. 5 (b), the lower part of the rear end face of the peripheral frame body 6B can be modified to be formed in a step-like convex shape so that a small amount of tea leaves is taken out first. is there. Further, as shown in FIG. 5C, the rear end face of the peripheral frame body 6B may be provided to be inclined so as to be flared from the upper part to the lower end. The invention described in claim 5 includes the embodiment as shown in FIG. 5 (c), in which at least the lower portion of the rear end face is formed as a flared slope.

FIG. 5D shows the bottom body 6A.
Is an embodiment in which is provided at an angle. In such a configuration, the discharge of the tea leaves is promoted by the inclination of the bottom body 6A. Incidentally, even in the case where the bottom body 6A is provided inclined as described above, it is possible to form and implement the lower rear end face and the lower front end face of the peripheral frame body 6B on the inclined surface 6s inclined rearward. .

The cutting tea stored in the housing 6 is discharged by opening the discharge opening E by moving the peripheral frame 6B horizontally, and for example, as shown in FIG. 6 (a). Alternatively, an opening / closing door 68 may be provided at the lower rear end of the peripheral frame 6B. Further, as shown in FIG.
The bottom body 6A is formed of a smooth plate, and the extruded plate 69, which is a part of the peripheral frame body 6B, is opened with the opening / closing door 68 opened.
The reaper may be pushed out toward the discharge opening E to discharge the reaper. Furthermore, the horizontal displacement of the peripheral frame 6B may be slight, and the relatively small discharge opening E may be opened, and then the bottom body 6A of the belt conveyor may be separately driven to discharge the cutting tea.

Further, the peripheral frame body horizontal shifting mechanism 6C may be implemented by a mechanism that moves by a chain or the like, or a mechanism that is performed by a link mechanism in the form of a pantograph, or a rack and pinion mechanism that drives the rack by a pinion. You may make it implement.

The cutting tea is discharged by a riding tea leaf picking machine 1.
, But the bottom body 6A is driven in the left-right direction of the housing 6 so that the reaping tea can be discharged from either the left or right or both ends. May be.

[0030]

According to the first embodiment of the present invention, the peripheral frame 6B or the bottom body 6A of the container 6 in the handling apparatus 5 is driven. Thus, it is possible to transfer the cutted tea in the container 6 to another without moving the cutted tea in a storage bag or the like. Is closed, moved on the truck T, removed one by one from the storage bag, and the troublesomeness of handling small storage bags one by one, such as taking out the reaping tea inside and putting it into the fresh leaf receiving device, etc., is eliminated. , Work efficiency is improved. In addition, since the containing body 6 can store the cutting tea at a desired position of the loading platform Ta of the truck T without being far from the traveling machine body 2, the tea ridge crossing type tea cutting machine can be transferred when the cutting tea is transferred. Has a center of gravity relatively close to the center of the traveling body 2 and has excellent stability. In addition, the structure necessary for carrying out the transfer is relatively simple, and the total weight is not so large.

According to the apparatus for handling reaping tea in a tea ridge running type tea mower according to the second aspect, the bottom body 6A is a belt conveyor, so that the structure is simple, so it takes up little space and is inexpensive. Implementation is possible, and the discharging operation is smooth.

Further, according to the third aspect of the present invention, the apparatus for handling harvested tea in the tea ridge crossing type tea mower has the lifting mechanism 7 for moving the container 6 in the vertical direction. The reaping tea can be loaded at a desired position such as the loading platform Ta.

According to the fourth embodiment of the present invention, the peripheral frame 6B of the housing 6 is horizontally displaced in the direction of the drive end of the bottom body 6A. Since it moves and the discharge opening E is opened, the discharge of the reaping tea is performed smoothly and speedily. Further, a driving device such as a motor is not required for the bottom body 6A itself. In addition, since the bottom body 6A on which the reaping tea is substantially placed is not moved and is fixed, the center of gravity of the riding tea leaf picking machine 1 does not collapse.

Further, according to the apparatus for handling cutted tea in the tea ridge running type tea mower according to the fifth aspect, the lower portion of the rear end face of the peripheral frame body 6B located at the end side of the belt conveyor moves rearward. Since the tea leaves are formed in a convex shape, the first take-out of the tea leaves becomes a small take-out, and the truck T and the riding-type tea leaf picking machine 1 at the time of the first feed are less shocked, so that the preferable feed can be performed.

Further, according to the apparatus for handling cutted tea in the tea ridge running tea cutter according to the sixth aspect, the lower portion of the rear end surface of the peripheral frame body 6B is formed as a flared inclined surface 6s. Therefore, the initial extraction of tea leaves gradually increases from a very small amount, and smoother extraction of tea leaves is performed.
