に構成されている。 To explain with a diagram, reference numeral 1 is a four-wheeled tractor, with one top link 2 at the upper position of the rear part and a pair of left and right lower links 3, 4 at the lower position.
will be established. Reference numeral 5 denotes a hydraulic arm which is moved up and down by a hydraulic mechanism, and the lower ends of connecting rods 6 and 7 whose upper ends are pivoted to the free ends of the arms 5 are pivoted to the front and rear intermediate positions of the lower links 3 and 4, respectively. do. The top link 2 is formed of a pair of front and rear threaded rods 10, 11 and a threaded cylinder 13 with a handle 12, and has a so-called turnbuckle structure. A vertical lifting frame 14 is attached to the rear end of each of the top link 2 and lower links 3 and 4. Conventionally, the elevating frame 14 has generally been L-shaped when viewed from the side, but in the present invention, it is |-shaped and has a straight shape, which makes the structure that much simpler. When viewed from the front side of the tractor, the elevating frame 14 is square-shaped, and a pair of left and right vertical protrusions 16 and 17 are provided protruding from the upper surface of the connecting body 15 at the top, and between the protrusions 16 and 17 Insert the annular body 18 attached to the rear end of the threaded rod 11 of the top link 2, and remove the vertical protrusion 16,
Insert the left and right shafts 19 into the holes drilled in 17 and fasten them. The bases of horizontally protruding protruding rods 20 and 21 are welded and fixed to the outside of the lower end of the elevating frame 14, respectively. The protruding rods 20 and 21 are both formed to have a large diameter up to the middle, and the tip portions are formed into small diameter shaft portions 22 and 23, which have shaft holes drilled at the rear ends of the lower links 3 and 4. 24 and 25 fit into the small diameter shaft portions 22 and 23. An engaging protrusion 28 is attached to the upper part of the gap 26 of the elevating frame 14, and is always elastically protruded downward by the elastic force of a spring 27.
When the lever 29 is moved upward, the projection 28 moves upward against the elasticity of the spring 27. 30 is a box with a front metal plate 31 and left and right side metal plates 32, 3.
3. It is formed from a bottom metal plate 34 and a rear metal plate 35. Among the above, left and right side metal plates 32, 3
3 and the rear metal plate 35 are both removable and horizontally rotatable. The rear metal plate 35 shown in FIG. 7 is suspended by a shaft 36.
The engagement holes 37 and 38 of No. 6 are formed in two stages, upper and lower, so that the height can be freely adjusted. Bottom metal plate 34
Several metal pillars 39 are attached to the lower surface of the front and back. The metal column 39 is a square pipe formed by bending a metal plate into a square tube, as is clear from the cross-sectional views of FIGS. 8 and 9. When viewed from the side, the metal column 39 has a shape in which the upper surface 40 is in close contact with the lower surface of the bottom metal plate 35, but the lower surface 41 is horizontal from the front end 42 to the middle portion 43, and then gradually slopes upward. As shown in FIG. 10, the rear edge 44 of the bottom metal plate 35 is formed into an upwardly inclined blade portion 45. metal pillar 39
An engagement plate 46 is welded to the side of the front end 42 of the engagement plate 46, and a curved engagement hole 47 is bored in the front part of the engagement plate 46 as shown in FIG. The box 3 is attached to the shaft parts 22 and 23, respectively.
0 is rotatable about the shaft parts 22 and 23 from a horizontal use position to a hanging throwing position. When the box 30 is in the usage position, an engagement plate 48 that engages with the engagement protrusion 28 is attached to the upper part of the front metal plate 31, and an engagement hole 49 is bored in the engagement plate 48. An inlet 50 is formed in the bottom metal plate 34 of the box 30, and a plow 51 is attached to the inlet 50. The plow 51 protrudes below the lower surface 41 of the metal column 39. The embodiment shown in FIGS. 12 and 13 is
A configuration in which an angle steel 52 is attached to the blade portion 45 is shown. If the blade portion 45 is formed to be sharp according to conventional wisdom, it will break immediately. Therefore, in the present invention, the angle steel 52 is purposely brought into contact with the blade to form an extremely blunt edge. Also, Figure 12, 1st
4 and 15 show an embodiment in which blade bodies 55, 56 are attached to rear opening edges 53, 54 of side metal plates 32, 33. The blade bodies 55 and 56 are detachably attached with set screws 57. When viewed from above, the blade bodies 55 and 56 have a shape in which the outer side 58 protrudes directly rearward and the inner side 59 gradually opens outward. The blade bodies 55 and 56 protrude further rearward than the angle steel 52 of the bottom metal 34,
When removing snow, the blades 55 and 56 are first used, and then the blunt blade made of angle steel 52 is used.

し、削土を放擲し得る。 Since the present invention has the above-described configuration, the tractor 1
When the hydraulic arm 5 is rotated downward by operating the hydraulic lever attached to the hydraulic lever, the connecting rods 6 and 7 move downward, and therefore the lower links 3 and 4 move downward.
The box 30 supported by the top link 2 and lower links 3 and 4 moves downward, and finally the lower surface 41 of the metal column 39 attached to the lower surface of the bottom metal plate 34 of the box 30 comes into contact with the ground. In this state, the tip of the plow 51 will pierce the ground. When the tractor 1 moves forward, the soil dug by the plow 51 flows into the box 30 one after another from the inlet 50, and eventually becomes full. Next, operate the hydraulic system and hydraulic arm 5
is moved upward, the lower links 3 and 4 are pulled up by the connecting rods 6 and 7, and the lifting frame 14 is moved upward to raise the box 30 and transport it to the target position. At this time, the plow 51 remains in the state shown in FIG. 6 and the inlet 50 is open, but the soil is in a block state and does not fall further than the inlet 50. At the destination, when the lever 29 is manually operated to separate the engagement protrusion 28 from the engagement hole 49, the box 30 will fall backwards under its own weight, and the excavated soil can be thrown away.
