Definitions

  • the present invention relates to a blade adaptable to the front of a conventional forklift, with forks carried by an apron that can be raised or lowered, this blade being able to have various uses such as: leveling, cleaning, snow removal, etc. .
  • the blades for forklifts are usually intended to be mounted directly on the deck of a forklift, the forks being removed.
  • This solution has a major drawback; indeed, forklifts, especially those with only two drive wheels, have very poor grip on the ground when empty, by their design and their usual function, since most of the weight of the forklift is rear to balance the load on the forks.
  • the disassembly and reassembly of the forks and blades require time and labor.
  • the invention aims to eliminate these drawbacks, by providing a new solution which very significantly improves the adhesion to the ground of the assembly formed by the carriage and the blade, while facilitating the grip and removal of the blade and allowing to this blade to follow the unevenness of the ground.
  • the invention essentially relates to a blade adaptable on a forklift, comprising in combination: - A support provided with sleeves provided for the introduction of the forks of the forklift, this support receiving or constituting itself a counterweight; - a blade proper, located in front of said support; and - a blade holder frame, connecting the blade itself to the aforementioned support.
  • Such a blade can be quickly and easily adapted to any forklift, since it is taken directly on the forks of the truck, without transformation or disassembly. It also has a very particular advantage, which is the improvement in the grip of the machine constituted by the carriage fitted with this blade to the ground, this being due to the presence of an integrated counterweight, which remains loaded on the forks while working the blade.
  • the blade holder chassis is connected in an articulated manner, in particular around a horizontal axis, to the support which receives or itself constitutes the counterweight; thus, during the working stroke, the blade itself can play at height to follow the unevenness of the terrain on which it is used, while the carriage deck is placed at a height which allows the counterweight to be loaded on the forks.
  • the blade holder chassis is further connected to the support by means, such as at least one connecting rod or chain, which limit the angular movement of the articulation of this blade holder chassis relative to said support. So, when you want to raise the assembly, you just have to order the lifting of the forklift's deck: the support is then lifted by means of the forks, and this support itself drives the blade itself upwards , via the connecting rod (s) or chains supporting this blade.
  • the blade shown in the drawing, is intended to be adapted on the forks 1 of a forklift, not shown but of a conventional type, these forks 1 being carried by an apron which can be raised or lowered.
  • the main parts of the blade are: a support 2, a blade proper 3 and a blade holder frame 4 which connects the blade proper 3 to the support 2.
  • the support 2 has a main body 5 which constitutes a counterweight, either by its own mass, or by receiving a relatively heavy and inexpensive ballasting material, such as sand. Below the main body 5, there are two horizontal parallel sleeves 6 provided for the introduction of the forks 1 of the forklift.
  • the support 2 is also provided, at its lower part and towards the rear, with two feet 7 provided to rest on the ground and with two legs 8 defining a horizontal articulation axis 9, while a yoke 10 is provided at the front of the support 2 and in the central position.
  • the blade-holder chassis 4 comprises, in particular, two longitudinal members 11 whose front ends are joined, and whose rear ends are articulated to the support 2 along the axis 9.
  • the blade itself 3 is carried by the front part of the chassis 4 , in a manner which will be specified below.
  • the front part of the blade-holder chassis 4 is also connected to the support 2 by a connecting rod 12, the lower end of which is articulated along an axis 13 to a yoke 14 secured to the chassis 4 and the upper part of which has a slot 15 through which the axis 16 of the yoke 10 carried by the support 2.
  • the blade 3 can also be raised, so as to no longer come into contact with the ground 17.
  • the forks 1 of the forklift are raised high enough, with the deck, so that the chassis 4 and the blade 3 remain suspended from the connecting rod 12, the axis 16 of the yoke 10 retaining this connecting rod 12 by the upper end of the slot 15. It has been indicated by ⁇ , in this figure 4, the angle of movement of the articulation at 9 of the blade holder chassis 4 .
  • the blade 3 then comes to rest on the ground 17, and the support 2 itself comes to rest on the ground by its feet 7. Then moving the forklift back, the forks 1 are removed from the sleeves 6 along the arrow 18. Conversely, for gripping the blade, the forks 1 are introduced into the sleeves 6 along the arrow 19, by advancing the forklift, then these forks 1 are lifted to drive the support 2 upwards and thus take charge of it, with its counterweight 5.
  • the blade itself 3 is linked to the front part of the blade-holder chassis 4 by means of a plate 20 and a substantially vertical hinge pin 21, making it possible to orient this blade 3 either hydraulically or manually, as shown in particular in Figure 2; the blade 3 can, moreover, be mounted to oscillate relative to the plate 20 according to the arrows 22 (see FIG. 1). It is understood that various types of blades, and various means of orientation and control of these blades, can be used with the same adaptation system on the forks 1, depending on the applications envisaged: leveling, cleaning, snow removal, etc. ...
  • the means described can be replaced by any equivalent.
  • the connecting rod 12 is replaceable by a chain or by any other device providing a degree of freedom or a necessary stroke while ensuring retention.
  • the articulation of the blade-holder chassis 4 with respect to the support 2, illustrated in the particular form of a mechanical axis 9, can also be of any type; in particular, given the low value of the angle of movement ⁇ , this articulation can be produced simply in the form of one or more flexible blocks, for example made of rubber.
