Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tea-cutting machine for picking tea leaves, cutting branches, etc. while traveling over a tea ridge. The present invention relates to a tea ridge crossing type tea cutter having a new handling apparatus.

[0002]

BACKGROUND OF THE INVENTION Tea ridge crossing type tea leaf picking machines and the like, which perform tea cutting work while traveling over a tea ridge, have become widespread, and such a device can reduce labor and efficiency of tea cutting work. 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 the tea factory, the mouth of each of these storage bags is opened, and the work of taking out the harvested tea from inside is carried 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.

[0005] When an attempt is made to solve such a problem, as long as the conventional general technology is used, first, as shown in FIG. It is conceivable to place it directly above the truck T and insert it after inverting it, or to insert it by opening the bottom as shown in FIG. 7 (b). Such a technical idea has already become a well-known technology. However, when such a technical idea is to be applied as it is to a handling device of a tea ridge crossing type tea cutter, in any case, the container 6 'is largely moved toward the truck T away from the traveling machine 2'. This necessitates an unbalanced tea ridge-running type tea-cutter, and the structure for implementing it must be large and complicated. This leads to an increase in manufacturing costs and many disadvantages due to a significant increase in the total weight of the vehicle.

[0006]

[Technical Problems Attempted to Be Developed] The present invention has been made in view of such a background, and the applicant of the present invention does not pack cutted tea into small tea bags and carries it without carrying a large capacity container. From now on, we came up with a method of handling reaper that is to be piled up in trucks and other transport vehicles as it is, and furthermore, when putting reaper from the container into this truck and other transport vehicles, move the container as far away from the traveling machine as possible. Despite the absence, it can be put into the desired position of the transport vehicle, which provides good stability when transferring tea leaves of the tea ridge crossing type tea cutter, the structure is not complicated, and the gross weight of the vehicle increases significantly This is an attempt to develop a new tea-running type tea-cutter that can prevent such problems.

[0007]

According to a first aspect of the present invention, there is provided a tea ridge crossing type tea mower according to the first aspect, wherein a tea mower having a cutting blade is attached to a traveling machine which runs across the tea ridge.
In a device that includes a cargo handling device for accommodating cutted tea and that performs pruning of tea leaves, pruning of trunks, and the like, the accommodating body of cutted tea in the cargo handling device includes a peripheral frame body and a bottom portion provided at the bottom thereof.

As shown in FIGS. 1 to 3, the handling apparatus 5 includes a container 6 including a bottom body 6 </ b> A and a peripheral frame 6 </ b> B above the container 6, and a peripheral frame that horizontally displaces the peripheral frame 6 </ b> B in the container 6. It comprises a body horizontal shifting mechanism 6C and an elevating mechanism 7 for vertically moving the entire housing 6 up and down.

The housing 6 will be described. The container 6
As described above, the bottom body 6A includes a bottom body 6A to which a belt conveyor is applied as an example, and a peripheral frame body 6B provided above the bottom body 6A, and the peripheral frame body 6B has a roller 61a at the bottom. Conveyor frame 6 of bottom body 6A
0 is provided so as to freely roll in the horizontal direction. Surround frame 6B
Consists of a peripheral frame 61 and a net 62 stretched inside the frame as an example, but various modifications are possible.
For example, the present invention can be practiced with a metal panel having a plurality of ventilation holes. The lower front end of the peripheral frame body 6B is fixedly attached to the upper transport surface of the bottom body. When the peripheral frame body 6B moves horizontally, the belt on the transport surface side is simultaneously pulled and the bottom body 6A is moved. Is driven. Incidentally, it is preferable that the container 6 is configured to be detachable from the riding-type tea leaf picking machine 1. In this case, for example, at the time of starting the work or at the end of the work, a plurality of devices are stacked when being mounted on the vehicle and transported. For example, there is an advantage that it is possible to efficiently and tidy the mounting.

Next, a description will be given of the peripheral frame horizontal displacement mechanism 6C. As shown in FIGS. 2 and 3, a horizontal displacement rail 63 is provided on a conveyor frame 60, and a roller 61a at the bottom of the peripheral frame 6B is provided here. Is locked. Upper and lower rails 64 are provided on the left and right vertical frames at the front end of the peripheral frame 61, and the slider 65 is locked here.

6 is connected. With the above configuration, the peripheral frame 6
B slides backward while pulling the belt on the upper conveying surface side of the bottom body 6A by extending the cylinder rod 67a of the hydraulic cylinder 67, and the discharge opening E is opened between the B and the bottom body 6A. At the same time, maintain the position and orientation.

Next, the lifting mechanism 7 will be described. The elevating mechanism 7 can have various structures. Specifically, for example, as shown in FIG.
The conveyor frame 60 is locked so as to be able to move up and down freely.
It is possible to adopt a structure in which the conveyor frame 60 is connected to a chain 71 wound around the upper and lower sprockets. By driving the chain 71,
The conveyor frame 60 is moved up and down.

The elevating mechanism 7 is not limited to the above-described structure, but may be any of various types of mechanisms for moving up and down. For example, as shown schematically in FIG. 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 riding type tea picking machine 1 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) Adjustment of the position of loading the truck into the loading platform In order to load the truck T into 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 independently than moving the container 6 up and down together with the tea mower body 3. Of course, since the actual work site does not have such a condition of the loading area, the container 6 can be moved up and down a little.
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] The configuration of the tea ridge running tea cutter is as described above, but 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 discharged smoothly. 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. 5 (c), the rear end face of the peripheral frame 6B may be provided to be inclined so that the skirt spreads from the upper portion to the lower end.

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. .

Next, a tea ridge running tea cutter according to the present invention will be described. In other words, the discharge of the reaping tea contained in the container 6 described in the above embodiment is performed by opening the discharge opening E by moving the peripheral frame 6B horizontally. As shown in FIG. 6A, an opening / closing door 68 is provided at the lower rear end of the peripheral frame body 6B, and a roller for supporting the belt of the bottom body 6A, which is a belt conveyor, is shown in FIG.
(A) rotates the belt as shown by the arrow to drive the belt, and the opening / closing door 68 is opened from the discharge opening E to the bottom body 6.
It is possible to carry out the modification in such a manner that the cutted tea placed on A is discharged. 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, as other means for discharging reaping tea,
As shown in FIG. 6B, the bottom body 6A is formed of a smooth plate, and the extruded plate 69, which is a part of the peripheral frame 6B,
The reaping tea can be discharged by pushing it toward the discharge opening E with the opening / closing door 68 opened.

Further, the peripheral frame body horizontal shift 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 type 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.

[0027]

According to the first aspect of the present invention, the cuttable tea is stored in a small tea bag or the like, the mouth is closed one by one, and the cut tea is moved on the truck T. This eliminates the trouble of handling small storage bags one by one, such as taking out one by one from the storage bags and taking out the inside reaping tea and putting it into a fresh leaf receiving device or the like, thereby improving work efficiency. In addition, since the cutting body can be put into the desired position of the loading platform Ta of the truck T without moving the container 6 away from the traveling machine body 2 while holding the cutting tea, the tea ridge running tea is transferred at the time of transferring the cutting tea. The center of gravity of the mower is relatively located on the center side of the traveling machine body 2 and is excellent in stability. In addition, the structure necessary for carrying out the transfer is relatively simple, and the total weight is not so large. Also the bottom body 6
Since A is a belt conveyor, reaping tea is discharged smoothly and speedily.

Further, according to the tea ridge crossing type tea mower according to the second aspect, since the lifting mechanism 7 for moving the container 6 in the vertical direction is provided, it can be moved to a desired position such as the bed Ta of the truck T. You can load reaping tea.
