Problems to be solved by the invention

  In the conventional scraping method, the paddy fields were scraped using a halo to level the ground. However, the halo used for the scraping could overhang and cut the ridge. Since a great deal of labor is required to repair the shaved ridges, workers often work with a margin (about 10 cm to 20 cm) away from the ridge so as not to damage the ridge. . If the ground was leveled with some distance from the ridge, weeds would grow in the remaining area where the halo did not pass, which often hindered mowing.

  In addition, although a large paddy is scraped with a halo, it is not possible to level the paddy at once, so the paddy is scraped in a rectangular shape from the end of the paddy, leveled, and repeated back and forth, so that the paddy is leveled in a zigzag shape Was. However, in order to avoid a blank portion (landing leakage) in a portion where the halo passes, the worker performs the scraping operation so that the scraping portions of the halo are sufficiently overlapped on the outward route and the return route (or the adjacent portion). For this reason, it is necessary to reciprocate the scraping device more than in the case of the scraping operation in which there is almost no overlap with the scraping of the halo, and the workability is deteriorated.

  The present invention has been made in view of such a point, and an object of the present invention is to provide a harrow guide that can prevent damage to a ridge.

  It is another object of the present invention to provide a halo guide having a small overlap region of the scraping by the halo.

Means for solving the problem

In order to achieve the object of the present invention, the present invention is a device that is mounted on a scraping work machine that is mounted on a traveling body and performs a scraping work, and a length of a body frame and a mounting portion mounted on the traveling machine can be adjusted. It is characterized by comprising a guide member, a guide member provided from the middle to the tip of the guide member, a drive unit for driving the guide member from the main body frame, and a remote control switch unit for driving the drive unit. Here, the substitute scraping machine refers to an object composed of a traveling machine such as a tractor and a substitute scraper harrow.

Further, the present invention is characterized in that the guide member is formed of a metal chain or a bar pendulum.

In addition, the present invention is characterized in that a guide portion of a harrow guide is provided on the front outer side of the front tire of the traveling body.

The invention's effect

  By hanging the guide chain of the present invention on the paddy field, the operator can work with the guide chain as a guide, and the operability can be improved even by a non-expert, and a beautiful paddy field can be formed.

  In the hello guide according to the present invention, a guide indicating the scratched area to the operator can be displayed in front of the operator only by operating the guide section button. The operator drives the tractor or the like with the guide portion as a guide and performs scraping, so that the unscraped portion in the vicinity of the ridge can be significantly reduced, and the chance of damaging the ridge can be greatly reduced. Then, a scraping operation in which the overlapping area of the scraping portion of the paddy field is greatly reduced becomes possible.

  Since the guide can be displayed in a state of hanging forward, traveling on the second and subsequent roads is easy, and the overlap with the first road can be reduced in each step. As a result, the time for the scraping work can be reduced, and workability is greatly improved.

  Further, the guide chain of the present invention guides a paddy field, but the guide chain is suspended substantially perpendicularly to the paddy field by the weight of its own weight, so that accurate position guide can be achieved. Further, even if the vehicle body is tilted due to the unevenness of the paddy field, the guide chain always hangs in the vertical direction, so that accurate position guide can be performed.

  In addition, the guide arm can be opened and closed (length adjustment) only by a switch operation, and can be easily operated. The guide chain is automatically stored in the guide arm, so that it can be easily opened and closed and stored.

  Therefore, one paddy can be scraped efficiently, and the work efficiency of scraping is greatly improved.

Hereinafter, the configuration of an embodiment of the present invention will be described with reference to the drawings.

  The hello guide according to the first embodiment is a guide tool that is mounted on a traveling body such as a tractor to assist proper (efficient) driving of the traveling body. The body frame 1 includes a mounting portion 4 mounted on the traveling body, a folding or extending guide member, and a guide member 10 provided at an end from the middle of the guide member, and a gear for driving the guide member from the body frame. It comprises a motor section 8 and a remote control switch section 14 for opening and closing the motor section.

  The main body frame 1 is a pipe-shaped portion serving as a main skeleton of a halo guide portion, and is a member that is long in the left-right direction and is made of an angle material, a pipe material, or the like. As the material, steel, stainless steel, aluminum, resin, carbon fiber, wood and the like can be used, but aluminum is most preferable in terms of corrosion resistance, light weight and workability. The length in the left-right direction is desirably about 100 cm to 250 cm in order to travel on the road with the main body frame 1 as it is (without extending the guide portion). (See Fig. 1)

  The mounting part 4 to be mounted on the traveling body such as a tractor is a connection part for mounting the hello guide to the front bumper (weight kit) of the tractor etc.Because the tractor front bumper shape differs depending on the tractor manufacturer, the front bumper is sandwiched from the front and The fixing shape is not particularly limited as long as it can be fixed with bolts.

  The guide member is a guide member that folds or extends from the main body frame 1 to at least one side, and includes a left arm 2 and a right arm 3 in the first embodiment. When the arms are provided on the left and right sides (FIG. 1), it is desirable that the lengths are equal, and that when the arms are deployed on the left and right sides, the total length of the left and right arms and the body frame 1 is the same as the entire width of the expanded harrow. The material and shape of the guide member can be the same as the material and shape of the main body frame. However, the arm has a C-shaped cross section that opens upward, so that a later-described guide member (chain) is housed inside. I can put it.

  Although the chain 10 is hidden in a plan view in FIG. 1 in a plan view, the chain is drawn in a state of being bent in a horizontal direction in FIG.

  The guide member is set so that it can be suspended almost vertically from the arm to the paddy field and touches the water surface of the paddy field. A metal chain of about 8 to 12 mm and less than the front wheel diameter of the tractor (about 50 to 150 cm) is used. desirable. Other than a metal chain, an iron bar connected by connecting two metal rings can be used. The guide member is provided from the middle to the tip of the guide member.

  When a metal chain is used, even if the paddy has irregularities, the position can be accurately grasped without being affected by the irregularities. Further, even when wind is applied to the chain during work, the chain is less susceptible to the influence of wind due to its own weight, and the work can be performed smoothly, which is more suitable.

  The metal chain is located outside the front of the tractor front tire. By providing the tractor in front, the field of view from the driver's seat is improved, and the operator of the tractor can drive while looking at the hello guide guide. By providing the chain in front, it is not necessary to be affected by the waves generated in the paddy field.

  The drive unit 8 is a motor used to drive the guide member from the main body frame. The drive unit 8 can slowly expand or retract the guide member, and is preferably a low-speed gear motor for safe operation.

  The remote control switch unit 14 can operate each of the left and right drive units by attaching two toggle switches that can rotate forward and reverse the drive unit for opening and closing the guide member from the driver's seat.

  The hello guide having the above configuration is attached to the front frame of a traveling body such as a tractor (weight kit) (not shown) by sandwiching the body frame 1 from the front and rear through the mounting portion 4. At the time of installation, the harrow guide is the shortest and has the same dimensions as the tractor body, and can travel on the road in this state.

  When the tractor is operated and the user can get down to the paddy field and deploy the guide section, turning on the remote control switch activates the gear motor for driving, and the guide section (the left arm 2 and the right arm 3) moves one by one. Expand to the stretched length. At this time, a guide member (chain) having one end connected to the tip from the middle of the guide portion (left arm 2, right arm 3) hangs down in the paddy field. Thus, the operator can deploy the guide member while staying in the driver's seat without soiling the feet.

  After that, the scraping operation can be performed using the guide as a mark.

  When the scraping is completed and the guide member is folded, when the operator operates the remote control switch in the driver's seat, the gear motor for operating the guide member is inverted, and the guide members (the left arm 2 and the right arm 3) are moved. Can be shorter. At this time, the guide member (chain) having one end connected to the front end from the middle of the guide member is automatically stored in the C-shaped concave portion of the guide member.

This operation allows the worker to return to the garage because the width is such that the worker can pass on the return road.

  Also, the hello guide has the same width as the tractor width. The body frame is attached to the upper part of the connection to the tractor front bumper, hinges are attached to both ends of the body frame, guide members are attached to the hinges so as to overlap the body frame, the hinges become fulcrums, left and right guides When the member is folded or extended, the guide installed at the tip of the guide member can acquire the same width as the width of the rotary (harrow), and the power unit that drives the guide is , 12V motor and low speed gear.

The gear motors are respectively arranged near the fulcrum of the left and right body frames, a capricon is attached to the rotation shaft of the gear motor unit, connected to the round bar L-shape, and the tip of the round bar L-shape is connected to the arm by a chain. The power supply is taken out of the battery of the tractor body and connected to the gear motor. Two toggle switches for opening and closing the arm are mounted on the remote control box in the middle, and the left and right arms can be operated from the driver's seat by rotating forward and backward. By providing the remote control unit in the driver's seat, it is possible to drive and work safely while watching the guide unit (chain) in the left and right direction (45 ° diagonal direction) of the tractor. Therefore, the work can be performed without worrying about the overhang of the rear harrow, so that work errors can be reduced and the work time can be shortened, leaving no work left on the ridge, and the finish workability can be significantly improved.

As a result, the scraping time can be reduced, and the workability is greatly improved.
