TOOL

The present invention relates to a tool for transferring granular material 5, which tool preferably belongs to an agricultural machine and comprises a plurality of flexible rod elements arranged in the same line by means of a fastener.

Such a tool is a further development of a plank, i.e. 10 planks arranged at an angle to the ground so that it is inclined forward in the driving direction and smoothes out the uneven, plowed ground before it is harrowed or otherwise worked. The flexible rod elements may be too flexible and too elastic to the side.

It is an object of the present invention to provide a tool such as a preamble which is adaptable to different amounts of soil.

This object is accomplished in accordance with the invention by the characterization defined in the characterizing part of claim 1. : *: where.

Fig. 4 is a side elevational view of a rod element mounted on a plank according to the invention.

Fig. 1 shows a tractor 1 which pulls a chisel 2 whose front part is provided with a tool 3 according to the invention comprising a series of flexible rod elements 4 with a detachably elongated plate, for example a plank 5, attached to its front.

Fig. 2 shows the tool 3 in more detail and partially disassembled. The tool thus comprises a flexible rod element 4 with welded or otherwise secured working elements, such as hardened steel corner plates 6. The fasteners 7 are arranged at the opposite end of the flexible rod elements 4 for securing them to a transverse beam 8 which is in turn connected to the mandrel. 9. The transverse beam 8 may be rotatable and / or raised to position the rod elements relative to the ground. The rod members 20 are further provided with fastening means in the form of loops 10, which are preferably arranged on the side facing away from the direction of travel of the rod elements. The rod 11, * * i ** i, which has through holes 12 at its ends, can be pushed in one line *: * through the provided loops 10, then the rod is • · * ·: 25 fastened by pushing and securing the pins bodies in the hole 12.

In order to further stiffen the tool 3 of the invention 3 118411, an elongated plate, for example a plank of substantially rectangular cross-section, with fastening means 14 in the form of loops, can be fastened to the front of the rod element by aligning the holes align with the holes in the loops 10 of the rod elements and then insert the rod 11 through all the loops 10 and 14.

Fig. 3 is a side view 10 of the rod element 4 with the clamp 7 and the lower plate 6 removed for clarity. As shown in Figure 3, the rod element consists essentially of two parts: a straight part 15 and a t-bent part 16 having a center of curvature 17 around which the rod element can pivot when mounted on a beam. The loop 10, which forms the fastening member, is arranged at a predetermined distance from the outer end of the straight portion 15 of the rod element. The arrow 18 illustrates that corresponding loops may be positioned one or more along a straight portion toward a bent portion, depending on the need for stiffening of the rod members. Thus, a plurality of loops can be arranged in one and the same rod element.

. It is important to note that the tool of the invention * »can be used in many ways, such as with plank or ♦ 30 with or without air, and with many rods, with or without plank.

This is especially important when the ground is very hard and uneven at the same time, or when there are large, hard lumps and coarse plowing. The stiffener 5 of the wire yarn is thus a tool formed in accordance with the invention as described above, whereby the flexible rod elements can be locked together by a rod, which may advantageously be made of flexible steel or the like. By changing the dimensions and position of the rod, the board can be provided with 10 different properties, i.e. it can be more or less stiffened.

The tool may also be used for other purposes for moving granular material such as soil, sand, snow, etc. The implement can thus be used as a road plow or as a snow plow and can therefore also be arranged at an angle other than transverse to the direction of travel.
