Description

    TECHNICAL FIELD The present invention relates to a self-propelled or riding-type agricultural machine, and, of course, the field of manufacturing a guidance device that can guide the agricultural machine so that the course of the agricultural machine does not ride on the scissors, and its transportation and storage. From the field of providing and selling equipment and equipment necessary for assembly and mounting, materials necessary for those materials, machinery and parts, such as wood, stone, various fibers, plastic, various metal materials, etc. , The electronic components incorporated in them, the field of control-related equipment that integrates them, the field of various measuring instruments, the field of power equipment that moves the equipment and instruments, the electricity that is the energy and the electricity that is the energy source In general, industrial fields such as the oil field, as well as testing and researching these facilities and equipment, and exhibiting, selling, importing and exporting them. Fields, generals, and results of their use, facilities for making them, fields related to the collection and transportation of garbage generated by the operation of equipment, and recycling fields that efficiently reuse these garbage In addition, there are no technical fields that are not related to new fields that are currently unimaginable.

(Points of interest)
In Japan, as the agricultural population declines, there are increasing opportunities for elderly people and women to drive and operate riding tractors, improving visibility around the tractor driver's seat and reducing steering force in the event of power steering failure. It is important to further secure and improve the safety of agricultural machinery, such as improving the operability over a wide range and strengthening the safety cab and frame.

    The passenger tractor, which has been improved from various points of view as described above, can be safely operated and operated by elderly people and women. However, if the vehicle body becomes larger, the blind spots will increase. In particular, it becomes difficult to recognize the traveling trajectories of the front and rear wheels, and it travels over a undulating field, straddling the heels that are raised in a wavy manner, so that the left and right wheels are aligned with each other, and does not deviate from the trajectory. Such steering requires a certain level of skill, and is one factor that makes it difficult to realize safe and efficient farming.

(Conventional technology)
In order to overcome the problems of conventional agricultural tractors, the electromagnetic wave generation means mounted on the moving body, the guidance line formed by the information display continuously embedded in the ground, and the guidance line or guidance Recognize the deviation from the line and give information on the moving direction of the moving body (see, for example, Patent Document 1) or the light of the laser beam generator mounted on the work machine. Using the light as a mark, the distance between the work machine and the work machine is adjusted so that the vehicle can travel (for example, refer to Patent Document 2), or a GPS device and an internal sensor are mounted autonomously. An agricultural work vehicle that performs work, and a GPS antenna is arranged between the front and rear wheels and approximately at the center of the left and right sides of the vehicle to easily capture the behavior of the vehicle when turning and Becomes simple Unishi was intended (e.g., see Patent Document 3) or the like is scattered.

    However, the former guidance method (Patent Document 1) requires that a plurality of information displays be embedded in the ground along the traveling line in advance, and that the tractor is provided with electromagnetic wave generating means to provide sound and images. And the driving line must be guided to the driver, and the tractor guiding equipment requires a large amount of expenses. The technology (Patent Document 2) that makes it possible to adjust the distance from the work machine is to install a guide base equipped with a laser beam generator at an appropriate position on the tractor, and irradiate the laser beam on the edge to easily adjust the distance from the wrinkle to the tractor. Although it is possible to keep the distance constant, it is not impossible to steer the tractor along the scissors by irradiating the floor or joint with a laser beam using this, but the left and right front and rear wheels It is difficult to steer the vehicle so as to ensure that the vehicle is in good agreement, and if the driver is focused only on the laser beam irradiation position, the safety confirmation ahead may be neglected. For example, there are many disadvantages in application to the gluteal muscle running.

The latter technique (Patent Document 3) using a GPS device is intended to unmanned farm work by a tractor and to realize more accurate and safe farm work, but is mounted on an agricultural work vehicle. A GPS device that consists of a station unit and a reference station unit installed near the farm, and is used to detect information necessary for autonomous traveling, such as the speed, attitude, engine speed, and steering angle of the agricultural work vehicle. Position information such as a field sensor, a sensor arm that is attached to the front part of the left and right front wheels and rotates in contact with the crop, and a stock scanning sensor that can output a detection signal according to the rotation angle. It is necessary to combine various devices to obtain, and it must be said that a large upfront investment is required, and the knowledge and technology to increase the economic burden and to safely use complex functions. Become dispensable, unmanned, but desirable for large-scale agriculture, which aims to streamline, were those not be said necessarily a good thing easy to use for the majority of farmers elderly and women has become the main operator.

(Awareness of problems)
As mentioned above, many of the previously proposed guidance devices for various agricultural machines require a great deal of expense and knowledge and skills to master complex equipment. Although there is an economically feasible technology that can be used to guide the vehicle by irradiating a laser beam at a suitable place on the ground, even if it is used, it straddles the floor with the left and right wheels and follows the gluteal muscle It is difficult to accurately guide the tractor that travels, and even beginners, elderly people, women, etc. can travel accurately without departing from all the wheels from the furrows along the scissors of the field. The reality is that there are no technologies that can be realized yet.

(Object of invention)
Therefore, the present invention is a new technology that enables a tractor to be driven and operated accurately along a gluteal muscle even for beginners to skilled workers, and elderly and female farmers who have been increasing in recent years. As a result of the long-term trial and error, many trial productions, and experiments, we finally realized a tractor guidance device with a new structure. In the following, the configuration will be described in detail together with an embodiment representative of the present invention shown in the drawings.

(Structure of the invention)
As will be clearly understood from the embodiments representing the present invention shown in the drawings, the tractor guidance device of the present invention basically comprises the following configuration.
In other words, a vertical bar upper end type or rear upward inclined posture bar upper end type illuminator that can be aimed at a rod to be used as a travel guide at a position on the bonnet upper surface in front of the driver's seat of the agricultural tractor and on the driver's front line of sight Or at least one of the aiming frames with the graticules stretched on the front sight of the driver in the vicinity of the front hood of the tractor and the hood where the tractor is detachable and self-supporting and temporarily fixed. In this position, a horizontal sight bar that incorporates a left / right width adjustment mechanism for aiming at the right and left adjacent rods or joints to be used as travel guides is detachable, self-supporting and temporarily fixed. It is a tractor guidance device having a gist of a configuration composed of a combination with a star.

    In other words, the vertical top end type or rear upward tilt that can be aimed at the rod that should be used as a driving guide at a position on the driver's front line of sight on the front hood of the agricultural tractor driver's seat. At least one of the stance pole upper end type sight gate or the sighting frame with the graticule stretched is detachable, self-supporting, temporarily fixed, and near the bonnet front end of the tractor Similarly, a horizontal sighting rod that incorporates a left / right width adjustment mechanism for aiming at the right / left adjacent saddle or joint that should be used as a driving guide is detachable, self-supporting, and temporarily fixed at a position that is on the driver's front line of sight It shall be a combination with an illuminator that has become possible, and at least one of the meridians in the sight of the sight or the center of the aiming frame on the driver's forward line of sight shall be It matches the fence that the wheel should cross And the left and right ends of the horizontal illuminating bar of the illuminator are steered so as to coincide with the left and right adjacent rods or joints to be travel guides, respectively, and the tractor body axis is aligned with the center of the rod bed to be guided, The tractor guidance device is configured to be capable of being guided so as to prevent the deviation of all wheels from the intercostal runway.

    The tractor guidance device having the basic configuration as described above is more specifically shown as a driving guide at a position on the bonnet upper surface in front of the driver's seat of the agricultural tractor on the driver's front line of sight. At least one of the vertical rod upper end type or rear upward inclined posture bar upper end type sighting gate, which can be aimed at the power rod, or the aiming frame with a graticule stretched, is detachable and self-supporting via a vertical extension mechanism A sighting device that can be temporarily fixed, and for the purpose of aiming at the left or right side of the tractor where it is to be a driving guide in the same position on the driver's line of sight near the hood front end A tractor guidance device is formed by combining a horizontal illuminating bar incorporating a left-right width adjusting mechanism with an illuminator that is detachable, self-supporting, and temporarily fixable via a vertical expansion / contraction mechanism.

    More specifically, this is a vertical bar upper end type or rear end that can be aimed at a rod to be used as a travel guide at a position on the driver's front line of sight on the bonnet upper surface in front of the driver's seat of an agricultural tractor. A turret that can be attached, detached, self-supported, and temporarily fixed with a vertical telescopic mechanism for each of the upper-tilt-type sight gate and the aiming frame with the graticule stretched. And a horizontal sighting rod that incorporates a left-right width adjustment mechanism for aiming at the left and right adjacent saddles or joints that should be travel guides at a position that is also on the driver's line of sight near the bonnet front end of the tractor Can be said to be a tractor guiding device having a configuration that is configured to be combined with an illuminator that is detachable through a vertical expansion / contraction mechanism and can be independently and temporarily fixed.

    According to the tractor guidance device of the present invention having the configuration as described above, until now, the agricultural tractor is steered in response to the undulations and inclinations of the field ground so that all the wheels do not depart from the intercostal track. Since it requires many years of experience and skill, it has been considered very difficult and difficult to ensure safety for elderly people and women who are unfamiliar with the operation of agricultural machinery. A sighting device comprising at least one of an aiming frame in which the driver's seat is on the line of sight and the front end of the bonnet is on the line of sight, and a graticule is stretched, or a vertical upper end type or rear upward inclined posture bar upper end type sight And a horizontal illuminating bar that incorporates a left-right width adjustment mechanism, and an illuminator that can be detachably mounted independently and temporarily fixed, By aiming the type of turret on the fence that should be the travel guide, it is possible to travel so that the tractor body axis is aligned with the center of the same floor, or the meridian at the center of the aiming frame is the travel guide. Aiming at the center of the power bed enables the tractor body axis to be aligned with the center of the floor, and the left and right ends of the horizontal sight bar of the illuminator should be used as a travel guide. Steering to match each vehicle can prevent all wheels from departing from the intercostal runway, and it is safe and efficient for beginners, elderly people, and women who are not good at handling large agricultural machines. The excellent feature is that it is possible to realize agricultural work without problems and without failure.

    In addition, the turret and illuminator shall be provided with an up and down extension mechanism that can be adjusted up and down independently, according to the front gaze height of various drivers with different physiques. The height of the sighting device can be adjusted freely, and anyone can aim accurately by adjusting each vertical telescopic mechanism, making the operation of the tractor and the safety and work efficiency of farming work markedly The effect that it can be enhanced will be exhibited.

    In the case where the illuminator is composed of a combination of both a vertical rod upper end type or rear upward inclined posture bar upper end type sight and an aiming frame with a graticule stretched, a vertical rod end type illumination is used. Aim either the gate or the tilted-end-type illuminator to the fence that should be used as the travel guide, and the left and right ends of the horizontal sight bar of the sighting instrument should match the left and right adjacent fences or joints that should be used as the travel guide. The tractor body axis is aligned with the center of the anchorage floor to be guided, and can be guided so as to prevent deviation of all wheels from the intercostal runway. The horizontal illuminating bar position of the illuminator with respect to the latitude line can be visually confirmed, and the inclination state of the tractor body in the longitudinal direction of the traveling tractor can be confirmed, ensuring driving safety and better farm workability. The effect that it can ensure can be acquired.

    The turret unit has a support mechanism that uses a magnetic force attachment and detachment mechanism, and at least the bottom of the adsorption base is covered with a soft coating layer. In this case, a sighting frame having a graticule that is arranged on the driver's front line of sight can be easily and securely temporarily fixed at any location on the bonnet surface of the tractor. In addition, the base end covered with the soft coating layer has a feature that the bonnet upper surface can be reliably prevented from being damaged.

    If the sighting device has an aiming frame with graticules and displays a reference mark that can be aimed at the guide to be guided while traveling in the center of the aiming frame, the center position of the aiming frame is clearer Therefore, it is possible to easily aim at the kite to be guided, and to realize more accurate and smooth steering.

    The illuminator has an attachment / detachment mechanism using magnetic force, and a column body in which a telescopic type vertical extension / contraction mechanism is incorporated is erected on a base end base whose exterior bottom surface is covered with a soft coating layer, In the case where the vertical rod end type illuminator that is arranged on the driver's front line of sight is formed at the upper end of the column body, it becomes possible to secure a wider front field of view than that provided with an aiming frame, By aiming the vertical bar end type illuminator formed at the upper end to the eaves to be used as a travel guide, there is an advantage that it can be guided and steered easily and clearly.

    From the base end where the turret is near the bonnet front end of the agricultural tractor and near the rear of the illuminator, and is attached to the front of the tractor driver's seat. In the case where an inclined rod end type sight that can be aimed at the rod to be guided while the tractor is running is formed at the rear end of the inclined rod that extends obliquely upward and rearward, In any case where a frame is not provided, it can be aimed at the saddle to be used as a travel guide, and when combined with the aiming frame, the aiming frame, the graticule and the inclined rod end type illumination By visually recognizing the positional relationship with the gate, it is possible to clearly recognize the front / rear and left / right inclinations of the tractor body axis, thereby realizing more accurate and quick farming work.

    An illuminator is provided with an L-shaped support body having a base end that can be detachably self-supported and temporarily fixed on the chassis of the bonnet front end of an agricultural tractor or in the vicinity thereof, and forms an up-and-down expansion and contraction mechanism in the middle of it, A horizontal illuminating rod having a left / right width adjusting mechanism for aiming at the left / right adjacent saddle or joint to be travel guidance is provided at the upper end of the L-shaped support and on the driver's line of sight. Provided with a detachable level meter that allows the upper end of the L-type support to be displayed between the lateral sight bar and the front of the L-type support so that it can display the degree of tilting of the L-type support to the front, back, left and right. Then, the relatively heavy illuminator is temporarily fixed in or near the chassis, which is stronger than the bonnet, ensuring high rigidity, realizing more accurate guidance, and L-type support. Body forward avoiding contact with the front of the bonnet In addition to having the feature that the aim to the left and right adjacent rods or joints to be projected and travel guides can be made simpler, the horizontal illuminating bar with the left and right width adjustment mechanism, It is possible to freely adjust according to the width between the left and right adjacent ridges or the width between the ridges depending on the field, and further, it is possible to cope with various physique differences of drivers by adjusting the vertical expansion and contraction mechanism.
