Description

[Detailed explanation of the idea] [Industrial application field]

The present invention mainly relates to a tea tree cutting and leveling machine that shapes the upper surface of tea tree furrows into a predetermined shape, and in particular, a tea tree trimming machine that is equipped with a tea tree trimming device that guides cut branches and leaves in a predetermined direction when blowing them down between the furrows. It concerns a cutting machine.

[Conventional technology]

The tea tree ridges are formed roughly in the shape of an arc in the width direction.
The cutting work has been carried out several times. As shown in Fig. 4, the machine that performs this work includes a frame 6 extending along the arc of the upper surface of the tea tree ridge, and a clipper-type machine installed on the front edge side of the frame 6 that reciprocates in the length direction of the frame. Provided on the cutting blade body (upper blade 4, lower blade 5) and one side of the frame,
Pressurized air is sent to the transmission mechanism (transmission case 3) and prime mover 1 for driving the cutting blade bodies 4 and 5, and the tea leaf guide plate 7 provided on the rear edge side of the frame 6, and the mower on the tea leaf guide plate 7 is Blower 2 for blowing away leaves
and a frame support rod 6 that supports the frame 6.
A two-person tea tree trimming machine equipped with handles 8 and 9 provided on both sides of the handle 1 through fasteners 10 and 10 is known, for example, from Japanese Patent Application Laid-open No. 114121/1983. .

[Problem that the invention attempts to solve]

In the above-mentioned tea tree cutting and leveling machine, the tea leaf guide plate 7 is also formed in an arc shape along the arc of the upper surface of the tea tree ridge T (see Fig. 5), and one side end of this arc-shaped tea leaf guide plate 7 is The air outlet of the blower 2 is open and sends pressure air onto the tea leaf guide plate 7 to blow off the cut leaves.The pressure air sent from the blower 2 has an arc shape although it slightly spreads vertically. tea leaf guide plate 7
It is extremely difficult to allow the blades to pass over the cutting blades 4 and 5 evenly. For this reason, as shown in Fig. 5, even if the cut leaves that are light and have a small mass are blown away by the pressure wind, they immediately stall and fall into the furrows along the tea leaf guide plate 7. However, once the mass of the cut leaves is larger than a certain level, once the scattering speed is reached, the leaves will be blown a long distance and fall onto the adjacent tea tree ridge T. Furthermore, as shown in FIG. 6, this tendency becomes even stronger when the tea garden is inclined by θ degrees. If these scattered tea leaves are left as they are, they will easily get mixed into the new buds during the next tea picking and have a negative impact on the quality of the tea, so they must be removed, which requires a lot of effort. do. Furthermore, if the wind power of the blower 2 is weakened to such an extent that the cut leaves do not blow into the adjacent tea tree furrows, the cut leaves will not have the ability to fall between the furrows and will end up stagnant on the tea leaf guide plate 7. There was a problem.

[Means to solve the problem]

In view of the above circumstances, the present invention is characterized in that a scattering prevention guide is provided on the tea leaf guide plate to guide the cut leaves blown away by the pressure air from the blower in a predetermined direction.

[Effect]

With this configuration, the tea tree trimming machine of the present invention can
The cut leaves will not blow over the neighboring tea tree ridges,
It can be dropped reliably into the furrows, allowing efficient mowing work.

【Example】

An embodiment of the present invention will be described below with reference to the drawings. The tea tree trimming machine shown in FIG. 1 has the same configuration as that shown in FIG. A frame that extends along an arc in the width direction, has a predetermined width, and is supported on both sides by frame support rods 61. On the front edge side of this frame 6, there is a clipper-type blade consisting of an upper blade 4 and a lower blade 5. A cutting blade body is provided. The upper blade 4 and the lower blade 5 receive power from a transmission case 3 fixed to one side of the frame 6, and reciprocate in the length direction of the frame 6. Reduction gears, cranks, rods, etc. are installed inside,
The cutting blade body is driven back and forth. Also,
A tea leaf guide plate 7 is provided on the rear edge side of the frame 6, and a handle 8 and a handle 9 are attached to the frame support rod 61 via fasteners 10 on both left and right sides thereof. A blower 2 is fixed on the transmission case 3 with its blower port 21 facing the tea leaf guide plate 7, and a prime mover 1 is mounted on the blower 2.
and the transmission case 3 so as to transmit power coaxially thereto. A scattering prevention plate 1, which is also shown in FIG.
1 is fixed to the frame support rod 61 by set screws 12, 12. This scattering prevention plate 11
The top plate 11a, the side plate 11b, and the back plate 1
1c, with the side surface on the side of the ventilation port 21 and the front surface on the side of the upper blade 4 and lower blade 5 open.It may be made of a metal plate, but it is convenient to form it from a transparent synthetic resin plate as it allows for internal observation during work. belongs to. In the tea tree cutting and leveling machine configured in this way, the prime mover 1 is started to drive the blower 2, the upper blade 4, and the lower blade 5 (cutting blade body), and two workers handle the handle 8, 9, and move the cutting blade forward along the arc of the upper surface of the tea tree with the tea tree ridge T facing in between, as shown in Figure 3, the blade will cut the upper surface of the tea tree ridge T. Branches and leaves are cut in an arc shape. The cut branches and leaves are placed on the tea leaf guide plate 7,
Here, the pressure air generated by the blower 2 is sent to the air outlet 2.
1, the cut leaves are blown away in the length direction of the tea leaf guide plate 7. The blown tea leaves are guided by the scattering prevention plate 11 and fall between the furrows. At this time, the distance blown away by the pressure wind will differ depending on the mass of the tea leaves, but these will fall into the furrows while being mixed together within the scattering prevention plate 11. , it is reliably prevented from covering the adjacent tea tree ridges T. In addition, in the above embodiment, the frame 6, the cutting blade body, the tea leaf guide plate 7, etc. are formed in an arc shape along the width direction of the tea tree ridge, and the scattering prevention plate 11 is provided. , these can be formed into a straight line, and can be similarly attached to a pruning machine used for trimming, pruning, etc. of tea plants.

[Effect of the idea]

As explained above, according to the cut leaf scattering prevention device for the tea tree trimmer of the present invention, the scattering prevention plate (body) 11 is provided on the tea leaf guide plate 7, so that the pressure air from the blower 2 is prevented. Regardless of whether the mass of the cut leaves is large or small, the cut leaves that are blown away are guided in a predetermined direction by the scattering prevention plate 11 and can be reliably dropped between the furrows. The tea leaves fall onto the tea tree ridges, eliminating the need for effort to remove them. Furthermore, dust is guided along with the cut leaves in a certain direction by the scattering prevention plate 11 and falls into the furrows, thereby preventing dust from getting on the operator. Furthermore, the scattering prevention plate 11 has a simple configuration,
Since it is only necessary to attach it to the tea leaf guide plate 7, it can be easily attached to a conventional cutting and leveling machine. Furthermore, when the scattering prevention plate 11 is made of transparent synthetic resin, the flow of cut leaves can be observed from the outside during work.
