Description

Detachable fork device for the assembly of accessories in agricultural implements.

Technical sector

The invention falls within the technical sector agricultural, and in the specific section of accessories for the implements agricultural

State of the art

At present the accessories are mounted on implements using welded plates (to function as brackets) on the chassis, these plates are manufactured in it place where the accessory is assembled and not manufactured in series, They also depend on both position and shape and size of the accessory to install and of all those parameters that it deems Timely the builder.

This above results in the accessories not are easily interchangeable, because the distance between plates (stands) cannot be varied, and their shapes are not standard. Other consequence is the rise caused by manufacturing unitary.

The invention at hand allows the supports (forks in our case) can be removable, interchangeable and variable in position. So you can install accessories such as: a hydraulic cylinder, a rake, a ripper roller, etc., without having to go through the workshop, it is simply necessary to mount one or several fork devices on the chassis (chords are the accessory to be used), compatible with its size and position adequate.

Detailed description of the invention

The invention is mainly constituted by the following elements:

A fork (figure 1), whose base has two extremes, A and B:

TO)

End of the base formed by a straight and collinear extension with it, containing in its part end a transverse deformation and a through hole, centered this respect of the sides that contain the fork, the hole It may be threaded or not. The deformation serves to allow Base socket with a straight angular surface, and hole to allow the passage of a screw, or that this thread on he.

B)

End of the base formed by a straight extension bent at 90º in the opposite direction to the branches of the fork, containing at the end and centered on the extension, a rectangular through hole or a through hole circular with a keyway shaped recess. These holes have that way because they must allow to be crossed and to support Another piece of the device.

The fork contains circular holes interns (one or several) in their branches, threaded or not, being practiced in the direction perpendicular to them, and aligned in this address, may also contain the grooved branches longitudinally straight or curved, practiced in the same way as the holes. The holes and grooves serve so that through the branches can pass bolts, pins, screws, etc., of such that they can be linked (attached) to the fork of the device the desired accessories. The grooves on the branches attend to the specialized use of the device to mount certain accessories, which for example should have restrictions on their movement, taking the fork as a support point.

A tie pin (figure 2) consisting of a longitudinally straight bar, of rectangular section or square, which at least contains at one of its ends a circular hole with direction perpendicular to its axis longitudinal, also centered on the faces that go through In order to be able to receive the screw thread that Close the system, the hole may be threaded. The end that Contains the hole may be stressed (widened laterally), so that once the hole is made, the section of the bar at that point does not look very diminished. He other end may contain all, some or none of the operations described, (bored, threaded and stressed).

The screw (3) (figure 5), and where appropriate a nut, are two elements of standard and standard type, it include because they are pieces (especially the screw), indispensable so that the device can be closed and opened on the bar chassis of the implement on which it is mounted, since the screw to through its turn it can generate the necessary tension for a correct hold. The nut is an element of which you can dispense, as long as the pinhole end hole of tie down (figure 2), which receives the screw, this thread.

Description of the figures

Figure 1 shows a fork in the model more elementary, with only one hole that crosses the two branches, This type of fork is a good candidate to support to all those accessories (eg hydraulic cylinders), whose rotation on the axis presented by the centers of the two holes, you should not Be limited by the device.

Figure 2 shows a tie pin that It has its two ends drilled and stressed.

Figures 3, 4 and 5 illustrate the sequence of assembly of the main elements of the device, on a portion of a bar that could belong to a chassis of a implement.

Figures 6 and 7 are two examples that show two forks, which are adapted for mounting some accessories, with different support features.

The fork in figure 6 has two holes that cross the two branches, and the accessory element when joined to the device by two axes, it will be immobilized, it will not have the ability to turn in the support provided. This model of Rigid support can be used for example: by a reel or coil, for a counterweight, etc.

The fork of figure 7 has on the one hand a hole that crosses the two branches, and on the other two slots curved that also cross both branches. This provision is used. when the device should provide support, in which it should limit the rotation of the accessory. As an example of use would be to give support to the parallels of a rake, or to those of a roller runaway, since these elements need to be dragged to move around the surface of the land, and being this irregular must be able to vary in height from the point of support, causing turns in the latter. The dimensioning of the turn serves to avoid collisions of accessory elements on the implement structure, in addition to providing some positions relative for the correct installation of the accessory.

Embodiment

To be able to use the fork device Detachable first you have to consider two things:

TO)

Which is the dimension of the implement chassis section, or bar ready to hold the device ?. The basis of forks is not independent of the size of the section on the that you want to install, therefore you have to know the dimension of said section and choose the size of the device according to she.

B)

That accessory do you want to install to the device ?. There are accessories that They need only one device, two others, etc. Also have to be Knowing the support needs the accessory needs, some need free spin support, others need rigid support, others support with limited rotation, etc., for this purpose some are illustrated possibilities in figures 1, 6 and 7.

These two parameters put us on the way to choose the fork device we need, and that will be chosen from the repertoire of sizes and shapes that are used for behold

The device / s installation can be Perform according to the following steps:

1st The tie pin (2) will be introduced by the opening that the folded base of the fork (1) (figure 3), so that the pin hole of tie down (2), line up with the extension hole collinear of the fork base (1).

2nd The device that in the previous point is open, it is installed on the bar (4) (figure 4), so that the fork base (1) has its faces adjusted to those of the bar (4).

3rd Screw (3) (figure 5) is inserted through the colineal extension hole of the fork base (1), until it passes or threads on the tie pin (2). If he screw passes through the tie pin (2), at the end screw protrusion (3) a nut will be threaded, until the necessary tightening of the fork (1) and the tie pin (2) against the bar (4). If the screw (3) threads on the pin tie (2) (because we are in the case that it contains hole threaded), we will thread said screw until the tension is generated necessary for the fork (1) and the tie pin (2) stay tightly on the bar (4).

The installation of an accessory on one or various fork devices, will be done by passing through the fork and accessory other elements, such as: pins, bolts, screws, etc., so that the holes and fork grooves are aligned with those of the attachment, (we assume that the accessory is provided with holes, grooves, etc., which are necessary). The fitting of the accessory can be perform on the side of the fork, between the two branches, or that said accessory contains two other branches within which between The fork.

To position the accessory and avoid displacements, in some cases caps can be used, which they will be mounted on the pins, bolts, screws, etc.

The elements described above (pins, bolts, screws, etc.) will be provided with safety elements, that prevent accidental disassembly, in addition to allowing power assemble and disassemble the connection between device and accessory, of a simple way.
