Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automatic tea plant dew remover that shakes off rain and night dew adhering to tea plants using wind and vibration of a flexible membrane.

Traditionally, rain and night dew adhering to tea plants have been brushed off using bamboo brooms, but although this method removes rain and dew droplets, it removes the water film adhering to the surface. Since it cannot be removed, it is necessary to use a blower method or centrifugal method to remove the dew after collecting.However, since the work efficiency is extremely low, it is impossible to remove the dew using a highly efficient power tea mower. Worker fatigue was also a significant drawback.

However, in the automatic tea tree dew removal machine according to the present invention, a blower rotated by a prime mover is attached to a support frame so that the blower tube faces downward, and the blower tube has left and right branches adapted to the shape of the cut surface of the tea leaves. The pipes are connected, and each of the branch pipes is provided with a large number of outlets facing in the direction of travel.A flexible membrane is provided above the outlet to vibrate and hit the tea leaves due to the repulsive wind, and adjustment fittings are installed on both sides of the support frame. The handle is equipped with a handle that can adjust the angle of attachment to the support frame, so while the blower is operated by the prime mover and air is blown out from the outlet of the branch pipe, the handle can be placed on top of the tea plant while holding the handle. When the support frame is advanced, the wind blown from the outlet blows off the rain and dew attached to the tea confectionery, bounces upwards against the tea leaves, hits the flexible membrane and vibrates, and the vibrations hit the tea leaves and release the rain. Not only is the raindrops that adhere to the tea leaves completely removed, but the water film that remains on the tea leaves is also air-dried, leaving almost no dew on the tea leaves, making it easy to remove the dew after picking. Although it is no longer necessary, the work efficiency exceeds the reaping capacity of the two-person row cutting machine, the labor burden on the workers is light, and the air blowing in the forward direction prevents the dew that has been removed from getting back on the tea leaves. Since the dew is not applied to the operator, the vibration of the flexible membrane and the wind force are used to completely remove the dew from the tea leaves, making it very easy and efficient to use this machine.

Next, an embodiment of the apparatus according to the present invention will be described below with reference to the drawings.

In the figure, reference numeral 1 denotes a blower, which is attached to the support frame 2 so that its blower pipe 3 faces downward.

Reference numerals 4 and 4 denote left and right branch pipes connected to the blower pipe 3, which are curved to match the shape of the cut surface of the tea plant, and each of which is provided with a number of air outlets 5, 5 facing forward in the traveling direction at the bottom thereof. .

6 is a prime mover such as an engine that drives the blower 1, and is directly connected to the blower 1.

7, 7 is a stand, which is attached to the branch pipes 4, 4 by an intermediate attachment part 8.

9 is a flexible membrane, the base of which is attached to the branch pipes 4, 4, and the air outlet 5
.

Reference numeral 11.11 is a U-shaped handle attached to both sides of the support frame 2 using adjustment fittings 13.13 that pass through the pivot 12, and the pivot 12 has a head 14 at one end and a lever 15 at the other end. Mount the cam 16 on the shaft 17, loosen this cam 16, and attach it to the support frame 2.
Adjust the mounting angle of the handle 11 against the handle, and after adjustment, tighten it.
In addition to fixing it at an arbitrary angle, the handles 11, 11 are constructed by fitting a thick base pipe a and a thin tip pipe, and after adjusting the length by adjusting the fitting amount, cut and split (as shown in the drawing). (not shown) at the end of the base pipe a,
It can be tightened with a nut 18 and fixed at a predetermined length.

Since one embodiment of the automatic dew removal machine for tea plants according to the present invention is constructed as described above, the handles 11 and 11 are attached to the support frame 2.
Set the mounting angle of the handles 11', 11 in a comfortable position so that the wind outlets 5, 5 correspond to slightly above the tea plant, and then drive the blower 1 with the prime mover 6. Then, if two workers hold the above-mentioned handle 11.11 and move the support frame 2 along the tea plant in the direction of the air outlets 5, 5, the air outlet will fit in the shape of the cut surface of the tea plant. Wind blows out from 5, 5 and blows the rain and dew drops adhering to the tea confectionery forward, and at the same time, the wind that hits the tea leaves rebounds upwards and hits the flexible membrane 9, causing it to vibrate. The tea leaves are beaten to shake off the raindrops that adhere to the tea leaves, and the rain and dew that remains on the surface of the tea confectionery in the form of a water film is air-dried, leaving the tea leaves with almost no dew on them. , the efficiency is higher than the tea cutting capacity of a two-person power tea cutter, so the tea cutting capacity is not reduced in the slightest, and the worker only has to carry the weight of the blower while walking. Because the burden is light, it is possible to remove the dew from a vast tea garden easily without getting tired.

In particular, this device directs the wind outlet toward the front in the direction of travel, causing the dew to flow forward, which prevents the dew from re-attaching to the tea leaves that have been removed, and prevents the removed dew from falling on the worker. It is something that cannot be changed.
