JPH07112363B2 - Tea tree ridge management work machine with rails laid - Google Patents

Description

[Detailed Description of the Invention] [Industrial field of application] In the present invention, rails are laid between the ridges of tea tree ridges planted in rows, and the ridge work is performed while moving along the rails. It concerns a management work machine.

[Conventional technology]

Conventionally, a rail was laid between the ridges of the tea tree ridges planted in rows, and a tea picking machine was attached to the moving trolley that was installed between the left and right rails so as to straddle the tea ridges, and the trolley was moved along the rails. However, it is known that the tea leaves are cut off.

[Problems to be Solved by the Invention]

In the rail type tea picking device, one person can perform the tea picking work as compared with the case where the tea picking machine is supported by two workers and moved along the tea tree ridges. On the other hand, the rails are laid in the furrows, so it is possible to perform deep plowing work, middle tillage work, fertilizing work, and hem trimming (cutting) of tea plants. However, there was a problem that it was difficult to do with each dedicated machine. Also, if you try to perform the above work using the rail, the aircraft will move diagonally to the rail, the working part will contact the rail, for example, the rust-proof coating coated on the rail. There is also a problem that it may be damaged by peeling off.

The present invention has been made for the purpose of solving the above problems.

[Means for Solving the Problems]

In order to achieve the above-mentioned object, (1) a rail is laid between the ridges of the tea tree ridges planted in rows, and the ridge work is performed while moving the management work machine along the rails. The management work machine includes a pair of left and right drive wheels that are provided so as to be grounded on both sides of the rail, rolling wheels that are provided at front and rear positions of the machine body, and that are rollingly contacted with the rail, and both rolling wheels. And a control handle provided so as to project to the soil between the ridges and a steering handle provided so as to project rearward from the machine body. (2) The management work machine is provided on a rail. It is characterized by a pair of front and rear rolling wheels that make rolling contact, a working unit that can work on the tea tree ridges on the left and right sides of the machine body, and a work unit provided so as to project rearward from the machine body. .

[Action]

According to the present invention having the above-described configuration, the drive wheels are grounded and driven on both sides of the rail, and the rolling wheels provided at the front and rear portions of the machine body are rollingly contacted with the rails and provided between the rolling wheels. Since the working unit works on the furrow soil, the machine body moves forward and backward without tilting and performs stable work. Therefore, the working part does not come into contact with and damage the rail.

Since a pair of front and rear wheels are brought into contact with the rails to move the machine while working on the tea tree ridges on both the left and right sides of the machine by the working unit, highly accurate work can be performed on the tea tree ridges on both sides of the machine.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

In FIG. 1 and FIG. 2, reference numeral 1 is a rail laid at a substantially predetermined height in the widthwise central portion of the ridge B between the tea tree ridges A and A. Management work machine 2 that performs stirring, mixing, etc. after middle tillage, powder / granular fertilizer application
However, it is provided so as to work while moving along the rail 1. The management work machine 2 has an engine 4 mounted on a machine body 3 and is provided on both sides of the rail 1 so as to be grounded in a furrow B under a transmission 5 that shifts the power transmitted from the engine 4. And a pair of left and right drive wheels 6, rolling wheels 7 and 8 provided at the front and rear positions of the machine body 3 and rollingly contacting the rail 1, and the machine body 3 between the two rolling wheels 7 and 8 and the ridge B It is provided with a plowing hoe 10 which is vertically moved by a crank movement mechanism 9 so as to work on the soil, and a steering handle 11 which is provided so as to project rearward from the machine body 3. Protective covers 12, 12 are provided on both left and right sides of the management work machine 2.

In the management work machine 2 for the tea tree ridge A in which the rail 1 having such a structure is laid, a pair of left and right drive wheels 6 supported by the transmission 5 are provided in the ridge B on both sides of the rail 1 when performing work. It is grounded and driven, and the rolling wheels 7 and 8 roll on the rail 1 at the front and rear positions of the machine body 3, and both rolling wheels 7 and 8
The plowing hoe 10 provided on the machine body 3 in between performs plowing / medium plowing work on the soil in the furrow B, or stirring / mixing of the fertilized powder / granular fertilizer into the soil. At this time, the operator operates with the steering handle 11, but in the management work machine 2, the wheels 7 and 8 roll forward and backward with respect to the rail 1, and the pair of left and right drive wheels 6 are sandwiched on both sides of the rail 1. Since it is grounded in the furrow B, the machine body works on the soil in the furrow B by the plowing hoe 10 while moving along the rail 1 while supporting the front, rear, left and right sides. Therefore, the management work machine 2 can be easily operated, and the body tilts to the left and right to allow the plowing hoe 10 to move toward the rail 1.
There is no chance of contacting each other and damaging each other. or,
When turning the vehicle body at the end of the rail 1, the rolling wheels 7 and 8 can be disengaged from the rail 1 and can be easily turned by the left and right drive wheels 6, and can be moved to the next rail 1.

In the above configuration, the vertical adjustment of the management work machine 2 with respect to the rail 1 is performed by the vertical adjustment mechanism 13 provided on the support portion of the rolling wheel 7 and the vertical adjustment mechanism 14 provided on the support portion of the rolling wheel 8. The adjusting mechanism 14 is constructed as shown in FIG. That is, the bracket 16 is fixed to the stay 15 provided between the upper part of the wheel bearing case 5a protruding laterally from the transmission 5 and the machine body 3, and the base of the support arm 8a of the wheel 8 is bolted to the bracket 16. -The nut 17 is attached so that its rotation can be adjusted. Also, the bracket 16 has
Stoppers 18 and 18 for restricting the rotation range of the support arm 8a are provided, and the rotation of the support arm 8a can be adjusted within the range of the gap s with the rail 1. The gap s is smaller than the gap S between the rail 1 and the wheel bearing case 5a, and has a relationship of s <S. Therefore, the wheel bearing case 5a does not come into contact with the rail 1 even when the roller 8 is adjusted to the maximum position and the machine body is lowered by the vertical adjustment mechanism 14.

Further, as shown in FIG. 4, even when the distance between the rail 1 supported by the support 1a and the ridge B is large at the ends of the tea tree ridge A and the rail 1, the plowing depth by the tilling hoe 10 is small. Although it becomes slightly shallow, stable work can be performed, and when turning the aircraft, the rolling wheels 7 and 8 can be disengaged from the rail 1, and the left and right drive wheels 6 can easily turn to move to the next rail 1. Can be made.

Not only the working machine such as the management working machine 2 but also the rail 1 of the tea tree ridge A shown in FIGS.
A double-sided hemming machine 19 that simultaneously trims both hem parts may be movably mounted and used. That is, in the conventionally known double-sided hemming machine, one traveling wheel is provided under the main stay 20, the traveling wheel is grounded in the ridge, and the cutting blades 24, 24 are pushed while pushing the machine body forward with the steering handle 25.
At the same time, both sides of the tea tree ridge are trimmed at the same time, but in the present invention, the rolling wheel 21 is provided at the bottom of the main stay 20,
Rollers 23 are provided below the sub-stays 22 protruding rearward from the main stays 20 so as to be brought into rolling contact with the rails 1.

In this embodiment, the operator holds the control handle 25 of the double-sided hemming machine 19 and pushes the machine body forward to transfer the wheels 21, 23.
Move on the rail 1 while rotating, and the left and right cutting blades 24, 2
By 4 the hem of the tea tree ridge A on both sides of the rail 1 is cut off at the same time. In this case, the aircraft will have front and rear wheels 21,23.
Thus, it can be stably supported, can be moved lightly on the rail 1, and almost constant work can be performed only by paying attention to the inclination of the body to the left and right.

The present invention is not limited to the above two examples, for example, a deep cultivator for deeply cultivating the furrow, a control machine for controlling the pests of the tea tree furrow, a fertilizer machine for fertilizing the furrow or the root of the tea plant, and various management work machines. By providing a rolling wheel that rolls on the rail 1, each work can be performed while moving the machine body along the rail 1.

〔The invention's effect〕

As described above, the tea tree ridge management work machine in which the rail of the present invention is laid can have the following effects by having the above configuration.

The drive wheels are grounded and driven on both sides of the rail, and the rolling wheels provided at the front and rear of the machine touch the rails, and the working section between these rolling wheels is attached to the furrow soil. Since the work is performed, the work unit can perform stable work while moving without tilting forward, backward, leftward, and rightward. Therefore, the working parts do not come into contact with the rails to damage each other. Further, at the end of the rail, it is possible to easily rotate the drive wheel to move it to the next rail in a state where the roller wheel is separated from the rail.

By rolling a pair of front and rear wheels to the rails and moving the machine while working on the tea tree ridges on the left and right sides of the machine while working with the working unit, it is highly accurate for the tea tree ridges on both sides of the machine while moving the machine lightly. Work can be carried out. or,
Even when the work resistances of the left and right tea tree ridges by the working units are different, the machine body can be moved along the rail with good straightness.
