[Prior art]

 A rail is laid in the tea garden, and a work cart that automatically travels on the rail is equipped with a picking device, a pruning device, an insect control device, etc. as appropriate to promote automation and labor saving of the tea plantation work. The automatic tea garden management system has already been proposed by the present inventor as Japanese Patent Application No. 62-336317. In the above-mentioned conventional work trolley, since the plucking, pruning and pest control devices are installed inside the frame of the trolley frame, even if the trolley running rail is laid up to the ridge of the tea garden, it will be on the boundary wall. Since the edge of the frame came into contact with the end first, there was a flaw that left the ridge work in the tea garden. In addition, since the trolley was driven via a single drive roller directly connected to the motor shaft, it was impossible to climb a steep slope in a mountainous area with severe ups and downs, causing a situation in which it stopped. Furthermore, in the past, the guide roller for preventing wheel derailment was fixed, so if the traveling rail was tilted due to slack in the ground, etc., it was not possible to follow up and a wheel derailment accident was observed. Another problem is that it cannot be used on the work trolley and that it cannot carry tea bags or other storage bags.

Hereinafter, the present invention will be described with reference to the accompanying drawings. 1 to 4, A1 is a formed tea plantation, 1 is two rails laid along the longitudinal direction of the tea plantation, and a work carriage indicated by reference numeral 2 automatically runs on these rails to cut and fertilize tea. , Disinfection spraying, mowing and defrosting work are performed. Next, an example in which the work carriage 2 is equipped with a plucking device (automatic management device) C for cutting tea will be described. The work carriage 2 includes an elevating frame body (frame) 10 whose main constituent members are formed by joining vertical and horizontal members and an upright member, and a traveling frame body (frame) 20 which is also formed by joining the respective members. Has become. The elevating frame body 10 is made to have a width dimension slightly wider than the ridge width of the tea garden A1, and bracket portions 12 1 and 13 3 are attached to the left and right ends thereof. The bracket portions 12 and 13 of the elevating frame body 10 are mounted on the rails 21, 20 and 22, which are upright at the front and rear positions of the bases 23 and 24 of the traveling frame bodies 20 and 20 mounted on the rails 1. It is detachably mounted, and the screw rods 14 and 15 are rotated by the height adjusting handles 11 and 11 on both the left and right sides to vertically move the bracket portions 12 and 13 and the ascending / descending frame body 10. Incidentally, for each of the frames 10, 20 and each of the members 16, 19 described later, a square pipe or a pipe made of a light alloy such as aluminum is appropriately used.

In the elevating frame body 10 of the work carriage 2, a bridging frame 16 that connects the left and right bracket portions 12 and 13 is suspended between the upper sides 17 and 18 of the left and right bracket portions 12 and 13. A front edge frame 19 is provided. A mounting support 19A is provided upward at a central position of the frame 19, and support parts 17A and 18A projecting forward from the upper sides 17 and 18 of the bracket parts 12 and 13 are provided. Between the support tool 19A and the support portions 17A and 18A, a well-known semi-cutting scissors scissors H in which a fixed blade 30 and a movable blade 31 are formed in an arch shape is supported and mounted. This half-cutting scissors scissors H is arranged in the position shown by the solid line in FIG. 4 with the support tool 19A as the turning axis when going out of the tea garden, and when the work carriage 2 is returning, it supports the right side support portion 17A. The hooked portion fitted to the shaft 35 is removed, and it is turned to the left to fit the hooked portion to the support shaft 36 of the left supporting portion 18A. It should be noted that the scissors scissors H are adjusted by the handles 11 and 11 so as to be at the optimum height position with respect to the tea leaves of the tea garden A1, and are fixed by a fixing screw (not shown). The relative position between the tip position O of the pincer scissors H of the fixed blade 30 and the movable blade 31 and the front position O1 which is the front part of the traveling frame body 20 of the work carriage 2 or the supporting portions 17A, 18A and the like. As shown in FIGS. 1 and 4, the tip end position O of the scissors is fixed by projecting forward by an appropriate amount L (about 30 to 50 cm 3). A motor M1 or a motor for driving the scissors is attached to the scissors H, and a generator G1 or a battery for driving the work vehicle 2 is provided on the upper base 20A of the traveling frame body 20. In addition to the operation panel S, a well-known power plucking device including a blower B for collecting the cut tea leaves, a storage bag B 2 for the blower B, and the like is arbitrarily installed. The storage bag B2 filled with the cut tea leaves is mounted on the bridging frame 16 and is transported together with the movement of the work carriage 2.

On the other hand, on both side bases 23 and 24 of the traveling frame body 20, the traveling drive member (power unit) D of the work carriage 2 is provided, and the generator mounted on the bridging frame 16 of the elevating frame body 10. Drive motors M2 and M2, which are reversibly driven by G1 or battery, are provided. The sprockets 28 of the motors M2 and M2 are connected to the sprockets 25A and 27A of the two drive rollers 25 and 27 through a chain 26 and a guide sprocket 29. The two drive rollers 25 and 27 are mounted on the two rails 1 as shown in FIGS. Reference numerals 60 and 61 denote guide rollers for sandwiching both side surfaces of the rail 1 and are provided on the respective side bases 23 and 24. As a result, derailment of the work carriage 2 is prevented, and stable running is guaranteed. Therefore, the start, stop, and reverse start of the motors M2, M2 are driven by the operation panel S by the four driving rollers, and the forward, backward, and backward movements of the work carriage 2 are securely performed without slipping even on a steep slope. It is configured to run. Further, steps (boarding platforms) 40, 41 on which workers can be mounted are attached to the rear ends of the left and right bases 23, 24 of the work vehicle 2 so as to be mounted from above, and the storage bag B2 This will improve the workability and safety when boarding during replacement of the vehicle or during various maintenance.

The self-propelled work trolley 2 for tea fields of the present invention has the above-mentioned configuration, and its operation will be described below. The forward, stop, and backward movements of the work carriage 2 are the moving force for rotating the four drive rollers 25 and 27 all at once by the operation control of the motors M2 and M2 using the generator G1 as a drive source, and moving the rails on the rail. Is generated. In particular, since the driving force is generated by a large number of drive rollers 25 and 27, reliable driving is guaranteed without slipping on steep slopes, and a braking function with excellent stopping ability on steep slopes is also demonstrated. To do.

Further, since the tip end position O of the pincer scissors H of the fixed blade 30 and the movable blade 31 is arranged so as to project forward from the front position O1 of the work carriage 2, it is located at the ridge of the tea garden A1. The tea-scissors reach the ridges just before the work cart 2 approaches, and the tea-cutting work is efficiently and reliably carried out without leaving any uncut portion of the tea-cutting. This is demonstrated as an effective tea-cutting work when there is a fence 50 adjacent to the edge of the tea plantation A1 and a tea plantation of another person as shown in FIGS. This half-cutting scissors scissors H cuts one side of the tea garden by the arrangement of the solid line position shown in FIG. 4 with the support 19A as a turning axis when going out of the tea garden, and when the work carriage 2 returns, The hanging portion fitted to the supporting shaft 35 of the supporting portion 17A is removed and swiveled to the left, and the hanging portion is fitted to the supporting shaft 36 of the left supporting portion 18A, the direction is changed, and the tea leaves on the opposite side which are left uncut are cut. 5 shows the loci L1 to L4 ... of the work trolley 2 of the present invention with respect to multiple rows of tea gardens A0 to A3. The working mode of this embodiment is the same as the conventional one. There will be no uncut uncut tea at the ridges of the tea fields A0 to A3.

FIGS. 6 and 7 show a conventional work trolley 2 ', and the pinching scissors position O is determined by the front frame position O1 of the work trolley 2'and the tip position O2 where the limit switch LS is arranged. Even on the far back side. Therefore, the uncut portion of the ridge of the tea plantation A1 corresponding to the retreated distance L'is generated, and the work efficiency is deteriorated. In addition, since only one drive roller 25 is arranged, the work vehicle 2'has a poor transporting ability, and it also slips on a steep slope and has a poor stopping ability on a steep slope, which may cause a runaway. Is high. Further, since the work carriage 2'is not provided with a step (board) on which an operator can board or a bridging frame base for carrying the storage bag B, it can be boarded when the storage bag B2 is replaced or at various maintenance. However, its workability and safety are extremely poor.

It is needless to say that the present invention is not limited to the above-described embodiment, and design changes can be made within the scope of the invention. For example, changing the arrangement direction and the number of the drive rollers 25 and 27 with respect to the rails, and changing the configuration to an approximate design of a hand-operated work carriage do not depart from the idea of the present invention.

[0015]

【effect】

 As described above, since the tea field self-propelled work trolley of the present invention is configured as described above, when the trolley approaches to the ridge end of the tea field, the plucking, pruning, and pest control device etc. first come to the ridge of the tea field. It has the effect of reaching the edge and efficiently performing tea field work without leaving the ridge work of the tea field. Also, since the trolley is driven by multiple drive rollers directly connected to the motor shaft, it is possible to easily climb a steep slope in a mountainous area with severe undulations. Can be followed even if the ground is loose due to slackness, etc., and the derailment accident is resolved. Since the work carriage is not equipped with a step (board) on which a worker can board or a frame stand on which a storage bag can be placed, the work cart can be boarded when the storage bag is replaced or during various maintenances. It has many advantages in terms of transportability and safety. Furthermore, there is an effect of satisfying the function as a tea field work cart (automatic tea field management device) that completely unmanners agricultural work such as tea picking and disinfection in the tea production process.
