Description

  The present invention makes it possible to equip both the forward and / or backward direction of the main body frame of the tea garden management apparatus of a small size (approximately the same size as that of the conventional one), and the turret of the turret. The present invention relates to a tea garden management device capable of changing the blade tip position of a blade.

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 that can be used for this teacup). 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 garden tailored to a width of about 1.8 m one by one through a half-row mower (which is about half of a full-pitch tea mower), the central part is left behind. There are improvements such as being prone to deep-cutting, 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 increases, the distance to reach the fertilizer will become longer, 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 operation, which is troublesome and takes time for the replacement operation. 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 the cutting blade body is attached 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.

  First, the first example shown in FIGS. 1 to 4 will be described. A configuration in which 1 can straddle a tea tree A (bamboo) having a width of approximately 1.2 m to a width of approximately 1.3 m (referred to as a width of approximately 1.2 m). The main body frame 1 is erected on the left and right wheels, crawlers and other traveling parts 2 and 2 (hereinafter, one of them is displayed in the case of a pair, such as left and right). . A rectangular tube-shaped elevating column 4 is externally fitted to each column 100 of the main body frame 1 so as to be movable up and down, and controls vertical movement of a tool post (tool) described later. The raising / lowering of the elevating column body 4 is constituted by a screw shaft 5 provided in the main body frame 1, a gear mechanism 6 (bevel gear speed reduction mechanism) meshing with the screw shaft 5 and / or a handle 7 for rotating the gear mechanism 6. The gear mechanism 6 and / or the screw shaft 5 is rotated by the rotation of the handle 7, and the lifting column body 4 is moved up and down by a gear (not shown) meshed with the screw shaft 5 by this rotation. . Instead of the screw shaft 5 and the handle 7, other mechanisms such as a cylinder may be used.

  In the figure, reference numeral 10 denotes a blade adjusting means. The blade adjusting means 10 includes a driven movable plate 12 pivotally attached to a bracket 11 provided on the elevating column 4 and a support rod 13 fixed to the driven movable plate 12. A pin 14 loosely fitted in the long groove 1200 of the driven movable plate 12, a bracket provided on the lifting column 4 to which the pin 14 is fixed, and a drive movable plate 16 pivotally attached to 15 The gear mechanism 17 provided on the support shaft 1600 of the drive side movable plate 16 and the adjustment handle 18 that controls the operation of the gear mechanism 17 are configured. The left and right support rods 13 (referred to as support rods 13) are configured to move simultaneously via the support shaft 1600. The gear mechanism 17 (gear reduction mechanism) is driven via the adjustment handle 18 to move the drive side movable plate 16. Due to the movement of the driving side movable plate 16, the pin 14 moves in the long groove 1200, and at the same time, the driven side movable plate 12 moves with the pivot 1201 as a fulcrum, and the tip side 13a of the support rod 13 moves in accordance with this movement. Move up and down. With this vertical movement, the blade edge 21a of the blade 21 of the tool rest 20 moves up and down. The cutter 21 refers to a tea cutter, a middle cutter, a pruning cutter, a leveling cutter, and the like. This type of cutter can be freely replaced, and is intended to improve convenience, economy, workability, and the like. To do. The blade adjusting means 10 described above is an example, and although not shown, any configuration can be adopted as long as the support rod 13 is movable via a drive mechanism and / or a movable mechanism.

  In the figure, reference numeral 23 denotes a bag that is detachably provided on a small carrier 24 provided on the main body frame 1. At the tip of the bag 23, there are a lock string 26 for hanging a tea bag 25, and this lock string. 26 has a stopper 27 for regulating 26. By suspending the tea bag 25 using this bag 23, a conventional large bag carrier (not shown) for bags is eliminated, and the apparatus is simplified, downsized or reduced in cost, and improved in workability. It may be useful for facilitating accommodation of tea leaves and avoiding damage to tea leaves during accommodation. Reference numeral 28 denotes a driver's seat, 29 denotes an operation mechanism, and A denotes a tea tree.

  Next, a second example shown in FIGS. 5 to 8 will be described. The basic configuration of the second example is the same as that of the first example. The main features of the second example are described below. Reference numeral 30 denotes a rotating mechanism, and the rotating mechanism 30 is a blade that supports a blade 31. The rotation mechanism 30 is provided to rotate the table 32. The rotation mechanism 30 is provided on a horizontal rod 321 extending in a substantially horizontal direction from the beam portion of the main body frame 1 and a screw portion of the horizontal rod 321 so as to be rotatable and movable up and down. The screw shaft 34 (high lead screw) and a rotating portion 35 pivotally supported on the tip of the screw shaft 34 are configured. Therefore, when the tool post 32 rotates, the screw shaft 34 moves up and down based on the horizontal rod 321. By this elevation, the tool post 32 moves up and down, and the entire tool 31 moves up and down. That is, it is configured to move up and down about 40 mm to about 80 mm. And this tool post 32 is clamped by the clamping piece 36 (fixing mechanism: stopper) provided in the main body frame 1 at different positions on the left and right. In this example, the rear end portion 320 of the tool post 32 is inserted into the holding piece 36 and secured. The holding of the rear end portion 320 by the holding piece 36 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 rest 32. The rotation mechanism 30 described above is an example, and other configurations are possible as long as the tool shaft 32 rotates and the screw shaft 34 moves up and down based on the horizontal rod 321.

  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 this example, the pitch of the screw shaft 34 is changed, and the height of the vertical movement is adjusted, so that there is an advantage that it can be adjusted to various heights such as tea tree A and / or mid-cutting. . Moreover, in another example, there is a feature that the intermediate cutting tool can be attached and / or used as both the forward side and the backward side of the elevating column body 4 and that the working efficiency can be ensured.

  Next, a third example shown in FIGS. 9 to 13-4 will be described. The basic configuration of the third example is the same as that of the first example, and its main features will be explained. In the figure, reference numeral 40 denotes a blade adjusting means.
