Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a tea-cutting machine for pruning tea leaves and pruning branches while traveling across a teacup, and in particular, a novel handling device for harvesting tea that contains and takes out the tea. This is related to the teacup straddle type tea mower.
[0002]
BACKGROUND OF THE INVENTION
A teacup-stretching type tea leaf picking machine that performs a tea-cutting operation while running across a teacup has become widespread, and the labor-saving and efficiency of the tea-cutting operation has been achieved by such a device. However, on the other hand, since such an object has been achieved, there has been a demand for the development of a technique that can further improve the work efficiency of the subsequent handling of the harvested tea.
[0003]
The current handling (handling) of harvested tea is based on the premise of relying on human hands, and a storage bag with a size of about 25 to 30 kg that can be transported by one worker is used as one unit. Each time they work, they are set on a tea cutter and when they are full they close their mouths and load them on a truck. On the other hand, even after being transported to the tea factory, the mouth of each of the storage bags is opened and the tea is taken out from the inside.
[0004]
On the other hand, as described above, for example, a riding type plucking machine or the like is used for the current tea cutting machine to save labor, and a large amount of plucking is performed once. It is becoming unsuitable for labor-saving tea mowers.
[0005]
By the way, when trying to solve such a problem, as long as the conventional general technique is used, first, as shown in FIG. It is possible to put it upside down and put it upside down, or to put it with the bottom open as shown in FIG. 7B. Thought is already a well-known technology.
However, when such a technical idea is applied as it is to the unloading apparatus of a teacup-stretching type tea mower, the container 6 'is moved away from the traveling machine body 2' to the truck T side in any case. As a result, the balance of the tea-crest-stretching type tea mower becomes worse, and the structure for carrying it out must be large and complex. This leads to many disadvantages due to an increase in manufacturing cost and a significant increase in the total vehicle weight.
[0006]
[Technical issues for which development was attempted]
The present invention has been made from such a background, and the present applicant does not carry the harvested tea in a small tea bag in a small tea bag. When thinking about how to load the harvested tea to be stacked, and when putting the harvested tea into the truck or other transport vehicle from the container, it is desirable that the transport vehicle be kept away from the traveling machine as far as possible. New tea that can be put into position, has good stability when transferring tea leaves from a teacup-climbing type tea mower, is not complicated in structure, and can prevent a significant increase in the total weight of the vehicle. This is an attempt to develop a straw-climbing type tea mower.
[0007]
[Means for Solving the Problems]

[0010]
Next, the tea cutter machine 3 will be described. The tea cutter body 3 is a type of tea bowl full plucking machine that plucks the whole surface of the tea bowl at once. This specific configuration is not particularly different from the conventional one, and details thereof are omitted.
[0011]
Next, the relay transfer device 4 will be described. The relay transfer device 4 is supported by the slider together with the tea cutter body 3 so as to be movable up and down, and is used for transferring the harvested tea to the handling device 5. As an example, a blower fan 40, a blower duct 41, And a discharge guide 42.
[0012]
Next, the cargo handling device 5 will be described. As shown in FIGS. 1 to 3, the cargo handling device 5 includes a container 6 including a bottom body 6 </ b> A and a peripheral frame body 6 </ b> B above the bottom body 6 </ b> A, and a peripheral frame that horizontally shifts the peripheral frame body 6 </ b> B in the container 6. It consists of a body horizontal shifting mechanism 6C and an elevating mechanism 7 for elevating the entire housing 6 up and down.
[0013]
The container 6 will be described. The container 6 includes a bottom body 6A to which a belt conveyor is applied as an example provided at the bottom as described above, and a peripheral frame body 6B provided above the bottom body 6A. The peripheral frame body 6B has a roller 61a at the bottom. It is provided on the conveyor frame 60 of the bottom body 6A so as to be able to roll in the horizontal direction. The peripheral frame body 6B includes, as an example, a peripheral frame frame 61 and a net 62 stretched on the inner side thereof, but various modifications are possible. For example, the peripheral frame body 6B is implemented by drilling a plurality of ventilation holes in a metal panel. It is also possible to do. The lower part of the 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 to pull the bottom body 6A. Is driven.
Incidentally, it is preferable that the container 6 is configured to be detachable from the riding tea leaf plucking machine 1, and in this case, for example, a plurality of devices are stacked when being carried on a vehicle at the start of work or at the end of work. For example, there is an advantage that it can be efficiently arranged and mounted.
[0014]
Next, the peripheral frame horizontal shifting mechanism 6C will be described. As shown in FIGS. 2 and 3, a horizontal shift rail 63 is provided on the conveyor frame 60, and a roller 61a at the bottom of the peripheral frame 6B is engaged therewith. Is done. Further, 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 thereto. The slider 65 and the conveyor frame 60 are connected by a link 66. The conveyor frame 60 is provided with a hydraulic cylinder 67, and a cylinder rod 67 a in the hydraulic cylinder 67 is connected to the link 66.
With the above-described configuration, the peripheral frame body 6B slides backward while pulling the belt on the upper conveyance surface side of the bottom body 6A by extending the cylinder rod 67a of the hydraulic cylinder 67, and between the bottom body 6A and the bottom body 6A. The discharge opening E is opened and the position and orientation are maintained.
[0015]
Next, the lifting mechanism 7 will be described. The elevating mechanism 7 can have various structures. Specifically, for example, as schematically shown in FIG. 4A, the conveyor frame 60 is engaged with the mast 70 so as to be able to move up and down. It is possible to adopt a structure in which the conveyor frame 60 is connected to a chain 71 wound around upper and lower sprockets. By driving the chain 71, the conveyor frame 60 is moved up and down.
[0016]
The lifting mechanism 7 can be applied to various mechanisms that move up and down in addition to the structure described above. For example, as shown in a skeleton form in FIG. 4B, a motor cylinder 72, an air cylinder, or a hydraulic cylinder. It is also possible to use a link mechanism 73 in the form of a pantograph as shown by a skeleton in FIG. 4C.
[0017]
The riding-type tea leaf plucking machine 1 has a specific form as described above, and this usage mode will be described below.
(1) Accommodating the harvested tea The harvested tea that has been harvested by the tea cutter body 3 is put into the accommodating body 6 through the relay transfer device 4 and accommodated. When the storage capacity is full, the truck T moves backward to the side of the loading platform Ta. Of course, it is possible to put in from the rear of the loading platform Ta of the truck T. In this case, the riding tea leaf plucking machine 1 is moved to the rear of the loading platform Ta.
[0018]
(2) Adjustment of loading position of truck to loading platform In order to load the loading position Ta of the truck T, the position of the container 6 is adjusted. Basically, the container 6 is first raised by the lifting mechanism 7. Then, for example, the riding tea leaf plucking machine 1 is moved a little to move the container 6 rearward to a desired position in the width direction of the loading platform 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 loading position. At this time, it is preferable that the container 6 is movable in the up-and-down direction. However, for example, the transfer work position on the truck T or the like is determined, and the riding tea leaf plucking machine 1 is placed in a platform shape on the platform T of the truck T. When the container 6 is at a higher position, it is not necessary to make the container 6 movable up and down independently, rather than moving up and down with the tea cutter body 3. Of course, the actual work site is not equipped with such loading conditions, so the container 6 can be raised and lowered as much as possible. In addition, a horizontal movement mechanism is provided to project the container 6 rearward. It is good also as movement in a horizontal direction so that it may obtain.
[0019]
(3) Loading When the loading position is determined, the circumferential frame body horizontal shifting mechanism 6C slides the circumferential frame body 6B rearward, and opens the discharge opening E while pulling and driving the conveying surface of the bottom body 6A. Then, the harvested tea on the conveying surface of the bottom body 6 </ b> A in the container 6 is piled up on the loading platform Ta of the truck T from the discharge opening E. It should be noted that all the harvested tea is introduced when the front end of the peripheral frame body 6B is positioned at the rear end of the bottom body 6A. 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, only the empty peripheral frame body 6B moves, and the cutting tea decreases. For this reason, the center of gravity of the riding-type tea leaf plucking machine 1 does not move greatly backward when the tea is discharged.
When all the harvested tea has been introduced, the peripheral frame body 6B is returned to its original position, the discharge opening E is closed, and after leaving the truck T, the container 6 is trimmed and positioned at a predetermined position to resume trimming.
[0020]
[Other Embodiments]
Although the form of the teacup-stretching type tea mower is as described above, various other modifications can be made.
For example, what is shown in FIG. 5A is a preferred embodiment in which the shape of the peripheral frame 6B is different. That is, in this structure, the lower part of the rear end surface (right side in the figure) of the peripheral frame 6B is formed on the inclined surface 6s spreading toward the bottom, 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 way, since the initial removal of tea leaves is a small amount, the shock received by the truck T and the riding tea leaf plucking machine 1 at the time of the initial insertion is reduced, and preferable insertion can be performed. In addition, since the lower part of the front end surface is also an inclined surface 6s, the last tea leaf is discharged smoothly. In the present specification, the rear end surface of the peripheral frame 6B refers to a surface in the direction of taking out tea leaves, and the front end surface is defined to refer to the opposite surface.
Similarly, as shown in FIG. 5B, it is possible to modify the lower end of the rear end surface of the peripheral frame body 6B so as to form a stepped convex shape so that the initial removal of the tea leaves is a small amount. is there. Further, as shown in FIG. 5 (c), the rear end surface of the peripheral frame 6B may be provided so as to be inclined so as to spread from the top to the bottom.
[0021]
FIG. 5D shows an embodiment in which the bottom body 6A is provided with an inclination. When comprised in this way, discharge | emission of a tea leaf is accelerated | stimulated by the inclination of 6 A of bottom parts. Incidentally, even when the bottom body 6A is provided in an inclined manner as described above, it is possible to carry out by forming the lower portion of the rear end surface and the lower portion of the front end surface of the peripheral frame body 6B on the inclined surface 6s inclined rearward. .
[0022]
Moreover, the cutting tea housed in the container 6 is discharged by opening the discharge opening E by moving the peripheral frame body 6B horizontally. For example, as shown in FIG. An opening / closing door 68 may be provided at the lower rear end of the body 6B.
Further, the horizontal shift movement of the peripheral frame body 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.
[0023]
Next, a teacup-stretching type tea mower according to the present invention will be described. This is a modification of the cutting tea discharging means in the above embodiment. That is, as shown in FIG. 6 (b), the bottom body 6A is formed of a smooth plate-shaped member, and the extrusion plate 69, which is a part of the peripheral frame body 6B, is opened with the opening / closing door 68 open. By pushing toward the part E, it is possible to discharge the harvested tea.
[0024]
Further, the peripheral frame horizontal shifting mechanism 6C may be implemented by a mechanism that moves with a chain or the like, or a pantograph-type link mechanism, or a rack / pinion mechanism that drives a rack with a pinion. It may be.
[0025]
Moreover, although the cutting tea is discharged from the rear of the container 6 provided at the rear part of the riding tea leaf plucking machine 1, either the left or right side is driven by driving the bottom body 6A in the left-right direction of the container 6. Or you may comprise so that cutting tea can be discharged | emitted from both ends.
[0026]
【The invention's effect】
According to the teacup-stretching type tea mower according to claim 1, the harvested tea is accommodated in a small tea bag or the like, the mouth is closed one by one, moved on the truck T, and the accommodation bag is also accommodated one by one. This eliminates the hassle of handling small storage bags one by one, such as taking out tea from inside, taking out the harvested tea inside, and putting it into a fresh leaf receiving device or the like, improving work efficiency. Moreover, since the raising / lowering mechanism 7 which moves the accommodating body 6 to an up-down direction is comprised, it can load a cutting tea in desired positions, such as the loading platform Ta of the truck T. FIG. In addition, since the harvesting tea can be put into a desired position of the loading platform Ta of the truck T without holding the harvesting tea away from the traveling machine body 2 while accommodating the harvesting tea, the teacup straddling type tea is transferred when the harvesting tea is transferred. The center of gravity of the mower is relatively on the center side of the traveling machine body 2 and is excellent in stability. In addition, the structure necessary for transfer can be made relatively simple and the total weight does not become so heavy.
