Description

  The present invention relates to a riding-type tea garden management machine that performs work by attaching a unit for managing tea gardens such as pest control, fertilization, pruning, and deep plowing as an attachment.

  Conventionally, riding-type tea garden management machines are dedicated machines for the management of tea gardens such as pest control, fertilization, pruning and deep plowing. For example, in the case of pest control, the control unit for pest control is used only for pest control. Fixed to the top of the mold body, the fertilizer unit was fixed to the body in the case of fertilization, the pruning unit was fixed in the case of pruning, and the deep plowing unit was fixed in the case of deep plowing. In recent years, a control unit, a fertilizer unit, a pruning unit, a deep plow unit, and the like are attached as necessary to perform work.

  Passenger-type tea garden management machines that run across tea trees have the main components (the body, drive source, cockpit, and other necessary items) placed above the tea tree, and the height of the tea tree is generally 50- Because of the size of about 100 cm, there was a problem that the fuselage exceeded at least 100 cm, the position of the center of gravity became high, the fuselage became unstable, and it was easy to tip over. In addition, the attachment is attached to the rear part of the tea garden management device that is stable without the attachment being attached, and the attachment protrudes outside the entire length of the traveling device, leading to a deterioration in balance. Also, if the attachment protrudes larger than the traveling device, there is a risk of hitting the tea tree or other obstacles when turning or reversing. Furthermore, in order to match the height of tea trees and obstacles and the height when working, the attachment is mounted so that it can be moved up and down.

  There are various types of attachments. For example, in the case of control, the chemical tank used in combination with the control unit was large and heavy, so it was fixed on the aircraft, but the shape of the liquid changed on sloping ground, the balance was lost, and the aircraft became unstable. There was a risk of falling. Therefore, the height of the chemical solution tank is lowered and a flat chemical solution tank is used, or the chemical solution is divided into a plurality of small chemical solution tanks. However, as mentioned above, the aircraft is higher than the 50-100cm tea plant, so the chemical tank placed on the aircraft is lowered or remounted, and the chemical tank on the aircraft is refilled with chemical. It was difficult to work.

  Next, in the case of fertilization, compost or fertilizer is put into the container, and the container has a spout for sprinkling the integrated compost or fertilizer between the tea trees, and the whole container is moved up and down to adjust the height. It was. In this case, the container containing compost or fertilizer was very heavy, and moving the heavy container to a higher position unbalanced the entire riding-type tea garden management machine, raising the risk of falling even on flat ground.

As described above, when attaching the attachment, the overall balance of the riding type tea garden management machine is easily lost, and it is dangerous. When the attachment is lifted, the attachment is tilted upward toward the front and rear center of the machine, and as it moves upward, the front and rear center of the machine Invention (Patent Document 1) having a structure located at the front, or an invention in which the control unit and the drive source are arranged as far as possible in the aircraft configuration, and the attachment is placed within the overall length of the aircraft after the control unit and the drive source. (Patent Document 2).

  In the conventional technique, a heavy object such as a chemical solution tank or compost or a fertilizer container has to be moved to a high position, resulting in a loss of balance and a risk of falling. Moreover, it was difficult to fit the attachment within the entire length of the aircraft, and when the attachment was not attached, the center of gravity moved to the front half, which was dangerous. Furthermore, as described above, there are many types of attachments, and it is an object to provide a riding type tea garden management machine that can be easily applied to each attachment.

  The first means of the present invention includes a gate-type airframe straddling a tea tree, left and right traveling devices for traveling the airframe, a work platform that is movable up and down at the rear of the machine, and an attachment that is movable up and down at the rear of the work platform It consists of an attachment part, and attaches an attachment to perform tea garden management work. By using this means, depending on the type of attachment, a heavy object can be placed on a work bed and a part directly working on the tea plant can be attached to the attachment attachment part. Since the work platform and the attachment mounting portion are each movable up and down, only the work platform or only the attachment can be moved up and down independently.

  According to a second means of the present invention, in the first means, the machine body, the work platform and the attachment mounting portion are arranged within the entire length of the traveling device. As a result, even if a heavy object is placed on the work bed, the balance is not greatly lost, and it is safe even if the work bed is slightly higher.

  By the above first means, the height of the work bed and the attachment mounting portion (attachment) can be adjusted as necessary, and the rise of the center of gravity position is suppressed as much as possible, and it becomes easy to achieve a balance. Therefore, there is no risk of falling. And, according to the work, lowering the attachment mounting part when attaching or detaching the attachment, or lowering the work loading platform for loading and unloading the chemical tank, fertilizer or compost container and replenishing the contents, reduce labor Can do. By making the work platform and the attachment mounting part movable up and down at two locations, more precise height adjustment can be performed at the rear attachment mounting part. Since the attachment and the attachment mounting portion are lighter than when the work bed is moved, the height can be adjusted easily and carefully. By these things, the device of the present invention can be applied to various attachments.

  The work platform of the present invention can be used as a platform other than the tea garden management work, and can be used as a luggage carrier cart even if no attachment is attached.

  By the second means, the position of the center of gravity can be brought close to the center of the traveling device, the balance is not so much lost, and it is safe even if the work platform is slightly increased.

  In the present invention, a state where no attachment is attached is shown in FIG. The airframe 1 has a gate shape straddling the tea tree, and has the traveling device 2 on both sides of the tea tree to cause the airframe 1 to travel. The traveling device 2 is driven by a driving source such as the engine 3 and the hydraulic pump 4 to travel. The seat 6 is a portion where the worker sits, and the worker operates the handle 7 to run the riding type tea garden management machine to perform work. The blower 9 is fixed to the airframe 1 because air blow may be required when performing the work by the attachment.

  A work bed 11 is provided at the rear of the machine body 1 and is provided so as to be vertically movable with respect to the machine body 1 by a work bed vertical cylinder 12 and a work bed fixing arm 13. The mechanism for moving up and down may be another mechanism or a motor.

  An attachment mounting portion 16 is provided on the rear portion of the working bed 11 so as to be movable up and down. The attachment mounting portion 16 is moved up and down by an attachment up / down motor 18 along the attachment up / down rail 17. In this embodiment, the attachment mounting portion 16 is moved up and down by the attachment up-and-down motor 18 and the attachment up-and-down rail 17, but it may be moved up and down by a cylinder and an arm in the same manner as the mechanism for raising and lowering the work bed 11. The machine body 1, the work platform 11, and the attachment mounting portion 16 are disposed within the entire length of the traveling device 2. The vertical movement of the work platform 11 and the vertical movement of the attachment mounting portion 16 are performed independently without any compatibility. However, it may be moved up and down in conjunction with each other as necessary.

  Step 19 normally protrudes in front of the sheet 6 as shown in FIG. 10 when used. When not in use or when transporting the riding-type tea garden management device, the step 19 is folded up about the shaft 20 as shown in FIG.

  Examples of control are shown in FIGS. In the case of pest control, a control unit 21 is attached to the attachment mounting portion 16 at a portion provided with a chemical solution outlet 23 for spraying a chemical solution, and a chemical tank 22 used together with the control unit 21 is placed on the work bed 11. In the operation of this embodiment, the chemical solution in the chemical solution tank 22 is poured into the control unit 21 by the chemical solution hose 24, and the chemical solution is sprayed from the chemical solution outlet 23 of the control unit 21 to the tea tree by blowing from the blower 9. In this embodiment, the chemical solution is sprayed by blowing air, but the chemical solution may be sprayed using a power sprayer instead of the blower 9.

  When the chemical tank 22 is placed on the working bed 11, the working bed upper and lower cylinders 12 are extended as shown in FIG. 4 to bring the working bed 11 to the lowest position. When the chemical solution tank 22 is replenished or the chemical solution tank 22 is lowered, the working bed 11 is moved to the lowest position. The work bed upper and lower cylinders 12 are contracted as necessary, and the work bed 11 is raised as shown in FIG. Although FIG. 5 is the highest position, it is possible to stop at a height between FIG. 4 and FIG. 5, so that the work platform 11 does not hit the tea tree 26 when straddling the tea tree 26 with the riding type tea garden management machine. Determine the height.

  When adjusting the height of the chemical outlet 23, the attachment up / down motor 18 is actuated to move the attachment mounting portion 16 up / down. When the attachment mounting portion 16 is at the lowest position, it is as shown in FIG. 6, and when it is at the highest position, it is as shown in FIG. When it is desired to move the chemical solution jet port 23 further upward, the working bed 11 is moved upward. In this case, basically, the operator controls to move each of the attachment vertical motor 18 and the work platform vertical cylinder 12, but when the attachment mounting portion 16 is to be moved outside the allowable range of the attachment vertical rail 17, For example, the work bed upper and lower cylinders 12 may be moved in conjunction with each other.

  An example of fertilization is shown in FIG. A container 31 containing compost or fertilizer 34 is placed on the work bed 11 after the work bed 11 is at the lowest position, and a spraying port 32 is attached to the attachment mounting portion 16 as a fertilizer unit, between the container 31 and the spraying port 32. Are connected with a fertilizer hose 33. The spraying port 32 is provided with a shutter (not shown), and the shutter is opened during spraying and closed when not spraying. The spray port 32 should be as close to the ground as possible so that compost and fertilizer do not scatter. Since the vertical movement of the work table 11 and the attachment mounting portion 16 is independent and the distance between the container 31 and the spray port 32 changes, the fertilizer hose 33 should be flexible. When spraying compost or fertilizer, set the work platform 11 at the lowest position where it does not hit the tea tree, open the shutter, and run while spraying compost or fertilizer between the tea trees (where the travel device 2 travels).

  An example of pruning is shown in FIG. A pruning unit 41 having a pruning blade is attached to the attachment mounting portion 16, and the blower hose 10 of the blower 9 is attached to the blower pipe 42. The pruning unit 41 has a cutting blade (not shown). When pruning is performed, the attachment mounting portion 16 (work platform 11 if necessary) is moved up and down to bring the cutting blade to a desired cutting position. Then, it travels between the tea trees, harvests the tea trees, and drops the tea leaves harvested by the air blown from the blower pipe 42 from above the tea trees. Unlike normal plucking, this pruning is dropped between tea trees without harvesting tea leaves.
