Description

[Detailed Description of the Invention] This invention relates to a removable fork device that is attached to a crawler-type loader or tractor used for earthwork work, mainly field preparation for farmland improvement.

It is well known that angle blades are conventionally installed in place of the blades of track-type loaders, but in work centered on field preparation for farmland improvement, not only earth and sand but also compost, drainage pipes, and other materials are used. In order to load and unload a wide variety of materials, such as the transportation of This work was inefficient, and the costs were high because many models were used.

This idea was made in view of the above-mentioned circumstances, and by attaching a fork device to the blade (earth removal plate) attached to a track-type loader, it can be used for fork work in addition to its normal function as an earth removal plate. It is intended to provide a detachable fork device.

Hereinafter, a detailed explanation will be given based on FIGS. 1 to 4. FIG. 1 is a perspective view showing an embodiment of the detachable fork device of this invention attached to a blade. At the upper end 1a of the blade 1, there are four The plate-like extension plate 11 having an even number of U-shaped notches 11a is fixed by welding or the like. In the notch 11a of the extension plate 11, a pair of fork tines 2 having an engaging portion 21 with an inverted U-shape at the upper end are inserted through a locking means such as a bolt as shown in FIG. 3 or 4. Fixed. The back surface of the lower end of this fork tine 2 is attached to the front surface of the blade 1, with the lower end back surface coming into contact with the cutting edge 3 of the blade 1. The reason why the notches 11a are provided in an even number of 4 or more is for adjustment when the mounting width of the fork tine 2 is to be narrowed or widened. Figures 3 and 4 are exploded explanatory views of the state in which the engaging part 21 at the upper end of the fork tine 2 is fixed to the extension plate 11 fixed to the upper end of the blade. and fix the embedded bolt 12a there, and the engaging part 21 of the fork tine 2
2a, it is fixed with a nut 12c, or the seated engaging portion 21 is directly tightened with a bolt 12b. Further, it is preferable to fit the fork tines 21 into the notches 11a by hitting them with a hammer. In the example shown, 1
Although a method of fixing the fork tines 2 with bolts or the like is shown, it is also necessary to fix the fork tines 2 preferably with two bolts for the safety of the fork tines 2.

As explained in detail above, according to this invention, by removably fixing the fork tine to the extension plate via bolts etc., it can not only be used as a normal earth removal plate (blade), but also can be used for material transportation using a conventional crane. Loading and unloading work can be done with the fork device of this invention, and the installation width of the fork tine can be changed freely, which increases the versatility of fork work, that is, adjusting the length of the fork tine according to the material to be processed. There are advantages to doing so. In addition, since there is no need to separately prepare equipment such as a crane as in the past, there is an effect that the number of models for work can be reduced.
