Description

[Detailed description of the invention] The present invention relates to the structure of a two-person tea leaf plucking machine, and in particular, in a structure in which a wind barrel is attached to the front edge of the machine housing to blow air from the front of the cutting blade, the present invention This makes it possible to monitor the entire surface of the cutting blade without forcing the body into an awkward position during operation.

As shown in Fig. 1, the work using this seed picking machine is carried out by moving back and forth between the left and right halves of the tea ridge.

In other words, the arc-shaped cutting surface A is placed along one side of the top surface of the ridge, and two workers advance it while holding the handles a and a', and at the end of the ridge, the cutting surface A is moved along the top surface of the other one. It is something that progresses.

One of the important things to keep in mind during this work is to pick the ridges in an orderly and uniform manner without leaving any steps at the top of the ridge surface (the area indicated by arrow A in the figure).

If this leaves a step, the picked core leaves will be uneven in size, long and short, and will break or break into pieces, damaging the original leaves, which will not only cause various problems in later tea processing. , later pruning work becomes troublesome, and the appearance is also unsatisfactory.

However, in the conventional plucking machine of this kind, as shown in Fig. 2, one side plate of the machine housing protrudes significantly forward in order to erect the wind barrel C, and is located along the front side of the bottom plate A. The cutting blade e was completely invisible from the side.

In other words, when the worker holding the handle assumes a natural posture, his/her line of sight is at the position of the arrow opening, and in this situation, the cutting blade e cannot be seen, so the operator has no choice but to shift his/her working posture until his/her line of sight is at the arrow. I didn't get it.

As shown in Figure 3, this posture is half-hip, facing backwards in the direction of travel, and is tilted considerably backwards, forcing the upper arms to lift the aircraft in an extremely dangerous and painful position. Become.

In view of the above-mentioned serious dangers, the present invention forms a notch in at least the side plate on which the power unit is mounted, through which the cutting blade is exposed, so that good plucking work can be done in a natural posture. It is something.

Its structure will be explained with reference to FIG.

1 is one side plate on which the prime mover 2 fan 3 etc. as a power unit is mounted, 1' is the other side plate opposite to it, 4 and 5 are an arc-shaped bottom plate and top plate that match the upper surface of the brown ridge, respectively. 1,1
', a bottom plate 4, and a top plate 5 constitute a machine case with openings at the front and back.

Reference numerals 6 and 6 denote forward protrusions of side plates, between which a wind cylinder 7 connected to the fan 3 is constructed.

Reference numeral 8 denotes a cutting blade provided along the front edge of the bottom plate 4, the tip of which is located approximately on the same line as the front side 9 of the side plates 1', 1.

10 is a large number of discharge small pipes branched from the wind cylinder 7, and the cutting blade 8
Direct it to the vicinity.

11 is a handle on the power section side, and 11' is a handle on the other side.

12 is a storage bag that is detachably attached to the rear of the machine housing.

Reference numeral 13 denotes a notch formed in the side plate 1, which may be large enough to allow the cutting blade 8 to be seen through the notch.

In the illustrated embodiment, the side plate 1 is directly cut out to form the notch 1.
3, but a peephole of an appropriate size may be bored to form a notch.

Therefore, two workers face each other across the ridge, and handle handle 1.
1.11' and walk as described above, the frozen confections sheared by the cutting blade 8 are blown away by the pressure from the wind barrel 7 to the rear of the machine housing, and are stored one after another in the storage bag 12. During the forward movement and during the return journey, the operator holding the handle 11 does not have to take the unstable and dangerous posture as in the past, but naturally maintains the posture of holding the machine. Since the cutting blade 8 can be constantly monitored through the notch 13 of the side plate 1, the depth and shallowness of the cutting and the uniformity of the ridge top during the return trip can be clearly seen visually.

In the illustrated example, the notch is formed only on the side plate 1, but it may be formed in the same manner on the other side plate 1' as necessary.

According to the present invention described above, the structure is extremely simple, but it is difficult for workers who walk on narrow tracks while carrying a relatively heavy machine (approximately 16 to 20 kg) to adjust the fit between the cutting blade and the top surface of the ridge. This means that the candies can be monitored in an almost natural posture, improving safety and fatigue levels, and also making it possible to pick uniform frozen confections.

This invention is particularly effective when this work is carried out by women, girls, the elderly, etc., and it can also be used in tree gardens with tall trees or in nursery gardens with short trees. Monitoring of the cutting blade becomes significantly easier.

Furthermore, the present invention requires less material at the notch portion, which is extremely advantageous for this type of working machine, which is lighter than its competitors by even 1 g.
