FIG. 3 is an enlarged side view of the loading mechanism of the self-propelled manipulator of the present invention. As shown in FIGS. 1 to 3, the loading mechanism 4, a bucket 11 rotatably mounted about a mounting portion H on the front side of the packing box 2, after anteversion the crates 2,該荷box consisting link mechanism 12 for rotating pushing up the bucket 11 by transmitting Thus resulting pressing force anteversion. The link mechanism 12 includes a cylinder A that tilts the cargo box 2 forward by contraction , a fulcrum D to which a pressing force is applied by the forwardly tilted cargo box 2, a counter shaft fulcrum E that converts this force into a lifting force, and a bucket mounting portion H. The bucket has a lifting fulcrum I, and is constituted by a member that connects the fulcrums. Each said fulcrum and member are arrange | positioned back and forth on the centerline of a packing box width direction.

Further, the link mechanism 12 in the self-propelled manipulator shown in FIGS. 1 to 3 is connected between the counter shaft fulcrum E and the bucket lifting fulcrum I and the first lifting fulcrum G connected to the cargo box and the bucket. A link plate K having two push-up fulcrums F and a third push-up fulcrum L to which push-up force is transmitted is interposed between the fulcrums. The link plate K is rotatably attached to the cargo box at the first push-up fulcrum G, and the second push-up fulcrum F is rotatable while being separated from the cargo box. The fulcrum D to the link plate K are connected by a member 12a that connects the fulcrum D and the counter shaft fulcrum E, a member 12b that connects the counter shaft fulcrum E and the third fulcrum L of the link plate K, and a member 12c. Has been. (The member 12b and the member 12c are connected by a fulcrum J). The second lifting fulcrum F is connected to the bucket by a member 12d that connects the lifting fulcrum F and the bucket lifting fulcrum I. Each member is rotatable at each fulcrum.

Next, the effect | action in this invention is demonstrated using FIG. When the steering lever 15 of the boarding operation unit 3 in FIG. 1 is operated, the pump 13 provided behind the boarding operation unit 3 is operated and the hydraulic cylinder A is contracted. (Indicated by arrow X in FIG. 3). Due to the contraction of the hydraulic cylinder A, the cargo box 2 tilts forward about the cargo box rotation fulcrum B on the lower side of the bottom surface. When the cargo box 2 is tilted forward , a pressing force (indicated by an arrow Y in FIG. 3) is applied to the fulcrum D, and the pressing force is transmitted to the counter shaft fulcrum E by the member 12a. Is converted into a pushing force. The push-up force converted at the countershaft fulcrum E is transmitted to the third push-up fulcrum L of the link plate K via the fulcrum J by the members 12b and 12c. With the transmitted push-up force, the link plate K rotates around the first push-up fulcrum G in the direction of the arrow Z in FIG. 3, and the rotation causes the member 12d to transmit the push-up force to the bucket push-up fulcrum I. The bucket 11 is rotated upward and lifted about the attachment portion H of the bucket. By interposing the link plate K, the tip of the bucket 11 can be rotated to the upper surface of the packing box. As the tip of the bucket 11 rotates, the packing box returns to the original horizontal state. By retracting the cylinder A, the bucket is lowered and returns to the state before the rotation. In the present invention, the arrangement of the fulcrums, the lengths of the members and the link plate, etc. are appropriately designed according to the size of the packing box, the required lifting force of the bucket, and the like.

FIG. 4 shows the loading state of the object to be transferred by the self-propelled manual spreader of the present invention into the packing box, and FIG. 5 shows the loading flow. In order to load and recover the transfer object T such as compost loaded on the ground into the packing box 2, as shown in FIG. 4A, the cylinder A is contracted to tilt the packing box 2 forward, and the loading mechanism 4 The machine body is moved forward with the bucket 11 positioned near the ground and rushed into the lump of the transfer target T (when picked up). Thereafter, when the cylinder A is extended, as described above, the pressing force applied to the fulcrum D by the forward tilt of the cargo box 2 is the member 12a, the counter shaft fulcrum E, the member 12b, the fulcrum J, the member 12c, and the link plate K. The member 11d is converted and transmitted in the order of the member 12d, and is transmitted as a lifting force to the lifting fulcrum I of the bucket, and the bucket 11 is lifted upward. As a result, as shown in FIG. 4 (b), the bucket picks up the transfer object T (when lifting), and the tip of the pushed-up bucket 11 rotates to the upper surface of the packing box as shown in FIG. 4 (c). The transfer target T that has been moved and scooped can be loaded into the packing box 2 and collected (at the time of loading). The cylinder may be retracted to lower the bucket, and the above operation may be repeated to load the object to be transferred. Alternatively, as shown in FIG. You may go. In order to hit the ground while moving the transfer object loaded and collected in the packing box 2, it is only necessary to drive forward while driving the spraying mechanism 5, and the transfer object while moving forward with an easy posture facing forward. Can be sprayed.

The self-propelled manual spreader of the present invention has a link mechanism, and the bucket can be rotated as the cargo box is tilted forward, so that the loading operation can be performed only by a simple operation such as operating the cylinder with a travel lever or the like. can do. Furthermore, by interposing the link plate, it is possible not to obstruct the field of view during movement in a state where the bucket is rotated on the cargo box, and to keep the total height during movement low.

Furthermore, in the self-propelled manual spreader according to the present invention, loading and spreading work can be performed only by moving forward, and the loading mechanism 4 and the spreading mechanism 5 can be configured independently, so that optimum performance can be exhibited for each. It can be a structure. In addition, the reverse mechanism of the transfer target by a conveyor or the like is unnecessary, the visibility of the loading mechanism 4 part from the driver's seat is good, the work is easy, and the traveling device does not step on the sprayed transfer target. There is an advantage that there is little or does not pollute the road.

In the self-propelled manual spreader of the present invention, the configuration of the spraying mechanism 5 can be appropriately set according to the spraying state and the like. In FIG. 1, it has the structure which has a pair of right-and-left vertical axis | shaft scraping rotary bodies 5a which scrape out the transfer object mounted in the cargo box 2 from the cargo box 2. As shown in FIG. The vertical rotary scraping rotor 5a is configured by implanting a plurality of scraping arms on a vertical rotary shaft. As the scraping rotary body, a horizontal shaft type scraping rotation constituted by arranging a plurality of scraping arms at equal intervals in the lateral direction and the circumferential direction on a lateral shaft installed over the lateral width of the packing box. The body may be used. Further, as another configuration, a scraping rotator for scraping the transfer target from the cargo box and a diffusion rotator for dispersing the scraped transfer target may be provided. The transfer object mounted on the packing box is first scraped out of the packing box by the scraping rotator, and then the scraped transfer object is diffused by the diffusion rotator. Thus, the object to be transferred can be dispersed uniformly and over a wide range. Examples of the configuration of the diffusion rotator include a configuration in which diffusion arms are attached to the upper surface of the rotating disk at appropriate intervals. In the case of using a vertical-axis scraping rotary body, the scraping rotary body and the diffusion rotary body can be configured as a common vertical rotary shaft, and there is an advantage that a transmission structure such as a chain and a transmission shaft can be omitted. Depending on the configuration of the scraping rotator and the diffusion rotator, a scraping guide or the like for assisting the spraying may be provided. The scraping rotator and the diffusion rotator are rotated by transmitting the output rotation of the prime mover 14 to the horizontal shaft or the vertical rotation shaft constituting them as described above. In addition, when using a horizontal axis-type scraping rotor on the rear wall of the packing box, the left and right discharge vertical walls are detachably attached to the packing box, and the horizontal axis is supported on the discharge vertical wall. By attaching / detaching the discharge vertical wall to / from the packing box, the spraying mechanism can be detachably mounted on the airframe.

Such a conveyor includes, for example, a pair of left and right chains wound around sprockets provided at both ends of the front and rear rotating shafts, and a plurality of conveyor bars laid over the left and right chains. Composed. By providing the conveyor, the transfer object loaded in the packing box by the loading mechanism can be transferred backward without staying in the front. In addition, even when the spraying mechanism is not activated or when the removable spraying mechanism is removed, the conveyor can be driven so that it can be discharged from the rear of the packing box while being loaded and collected by the loading mechanism. It can be used to turn off compost.

The self-propelled manual spreader of the present invention has a partition wall that prevents the mounted transfer target from reaching the spraying mechanism at a position immediately before the spraying mechanism in the packing box, and a retracted state in which the partitioning action does not act. It may be provided so that the switching can be freely performed.
