Description

  The present invention is composed of a small vertical frame (about half the conventional size, the same applies hereinafter) and a small portal-shaped movable frame movably provided on the vertical frame. The present invention relates to a tea garden management device that can be equipped with a tool post in both the forward and / or backward direction of the frame mechanism of the tea plant management device and that can change the position of the cutting edge of the tool of the tool stand.

As is well known, a teacup formed from a conventional tea tree is tailored to a width of about 1.8 m, and various tea garden management devices (large-sized tea garden management devices, which can be used for this teacup, hereinafter referred to as a full-brush teabrusher, Is commercially available. However, in this large tea plantation management device, the following problems have been pointed out in the field tea plantation (farm).
(I) In the method of plucking a tea plantation of about 1.8m width through a half-row mower (about half of the whole mowing) one side at a time, the central part is left uncut or deep cut There are improvements such as being inferior in tea cutting accuracy and inferior tea cutting accuracy, or making it difficult to make a beautiful tea garden.
(B) The full-cut mower is expensive, and there are improvements such as high repair and / or maintenance (cutlery repair costs, etc.) of parts of the full-cut mower and increased running costs.
(C) The riding-type full-cut mower has to be lifted to the tea bag carrier and replace the tea bag, which is a heavy labor and has some improvements such as danger.
(D) If the tailoring of the tea plantation becomes large, the distance to reach the fertilizer will become long, the fertilizer efficiency will be inferior, or the amount of solar radiation at the base of the tea tree will decrease, making it unsuitable for the cultivation of high-quality tea, etc. There are improvements.
(E) Since the full-size mower is large, the minimum turning radius is large, requires a lot of headland, is inconvenient, or difficult to mount on a light truck (nearly impossible) In addition, in mountain slopes, there are fields with many narrow and narrow roads, so there are improvements such as difficulty in moving the tea cutter.

  As is well known, the conventional tea garden management device has various uses, and various types of tools are attached to the tool post attached to the device. For example, there are plucking (browning) blades, intermediate cutting blades, pruning blades, etc., which need to be replaced for each work, which is troublesome and takes time for the replacement work. For example, in a normal tea cutter, the cutting blade body is attached to the cutting blade support guide plate using a guide pin, so that the guide pin is released and the reciprocating drive unit is disassembled to drive the mechanism. The operation | work which cancels | releases the connection part with a cutting blade body is needed. Therefore, when attaching the cutting blade body to the tea cutter, it is necessary to adjust the gap between the pair of upper and lower cutting blade bodies. There are problems such as taking time.

  As a prior document for solving these problems, there is, for example, “teabrush machine with a detachable cutting blade unit” disclosed in JP-A-2002-360035 (referred to as document (1)). SUMMARY OF THE INVENTION An outline of the present invention is a modular cutting blade unit provided in a tea cutter having a cutting blade body reciprocally driven by an appropriate driving source, a cutting blade support guide plate that supports the cutting blade body, and a drive A reciprocating drive unit for converting the power transmitted from the source into the reciprocating motion of the cutting blade body is made into one assembly, and this cutting blade unit can be attached to and detached from the main body unit provided as a module in the tea cutter. Since it is the structure to attach and the cutting blade body which has been a troublesome work can be attached and detached by exchanging the unit, it can be easily and quickly performed even by a person who is not a manufacturer who is familiar with the handling of equipment. In addition, it has a feature that it can more reasonably manufacture products of different specifications through modularization.

Since the basic structure is the same as the above-described example, the description thereof will be omitted, and a structure not included in the above-described example will be described. The rotation mechanism 70 controls the rotation of the tool post 43 that supports the blade 44. The rotation mechanism 70 is, for example, substantially in the horizontal direction from the second column 12 and / or the beam member 14. A horizontal rod 71 extending to the screw shaft, a screw shaft 72 (high lead screw) provided on the screw portion of the horizontal rod 71 so as to be rotatable and movable up and down, and a rotating portion 74 pivotally supported on the tip of the screw shaft 72. To do. Therefore, when the tool post 43 rotates, the screw shaft 72 moves up and down based on the horizontal rod 71. By this raising and lowering, the tool post 43 moves up and down, and the entire tool 44 moves up and down. That is, it is configured to move up and down about 40 mm to about 80 mm. The tool post 43 is held by a holding piece 75 (fixing mechanism: stopper) provided at the left and right sides of the second column 12 and having different positions. In this example, at least one rear end portion 430 of the tool post 43 is configured to be secured to the gripping piece 75 by being inserted or fitted. The holding of the rear end 430 by the holding piece 75 is an example, and other fixing mechanisms such as bolts and hooks are also possible. As a general rule, a cutting blade is attached to the tool post 43. Note that the above-described rotation mechanism 70 is an example, and other configurations are possible as long as the screw shaft 72 moves up and down based on the horizontal rod 71 as the tool post 43 rotates.

  By adopting this configuration, for example, the mid-cutting operation is performed once every 4 to 5 years, and the tea tree A of about 900 mm is cut off to a height of about 500 mm. This mid-cutting work not only facilitates the work, but also aims to restore the vigor of trees, and it is necessary to cut off the tea tree A by about 400 mm. At this time, considering that it is usually impossible to cut off 400 mm at a time, the present invention cuts off about 100 mm on the forward path (going), cuts off about 50 mm on the return path (returning), and cuts about 150 mm in one round trip. By performing the dropping work, the configuration in which the tea tree A is lowered by dividing the tea tree A into 4 to 5 times usually has an effect that it can be omitted once, for example, and is useful, and the work can be made more efficient. Another advantage of this configuration is that, for example, in the case of a tea garden with one side headland, the tea cutter is lifted and moved backward by air. If you use this air transport, and the mid-cutting work becomes more efficient, the work efficiency will be better, and if you do the middle-cutting work in this way, the finished shape of tea tree A will be very beautiful. Thus, there is an advantage that it can contribute to the influence on tea tree A and the improvement of tea cutting accuracy. And since this rotation is a half-row mower, it has the feature that it can be easily and / or safe.

  In addition, in another example, there is an advantage that the pitch of the screw of the shaft 72 is changed and the height of the vertical movement is adjusted so that the height can be adjusted to various heights such as tea tree and / or mid-cutting. In addition, in another example, there is a feature that the cutting blade can be attached and / or used in combination with the advancing side and the retreating side of the movable frame 10 and the working efficiency can be ensured.
