FR2507859A1 - Step feed passing earth clods to belt - uses clod mass to deflect tongue and rotate shaft crank, causing push rod to close linkage and move roller onto belt - Google Patents

Abstract

The distributor feeds earth clods to a dispatch belt (19) without using the thrust from the fabricating machine or the advancing clod column. The mass of the last row of clods is used to stop the feed at the exact site of separation, using a rocking axle (5) to drive a return sprung (9) push-rod (7) actuating a lever (12,13) displacing a drive roller (16) onto the underside of the belt. Tongues sited under a distribution grill (4) deflect under the mass of the clod, rotate the shaft through a part turn, and bring about rod displacement through the intermediary of a crank (6). The rod may have counter cranking (8), its return spring may be stopped (10), and its free end (11) may displace the compass fulcrum. The compass extends between a fixed point (14) and the roller axle (15), and the roller is driven by a pinion (17) suspended on a pivot arm (18).

Description

 The object of the invention relates to an automatic device for distributing clods of earth.

 It is intended to equip any machine allowing the continuous production of clods of all kinds in receptor packaging or other products in crates or other.

 It is known to use at the outlet of clod making apparatuses having predetermined dimensions, devices allowing their orderly packaging for their use in crops of all kinds; These devices must be adapted to the producing device and the very push of the clods on the receiving surface is used to ensure mechanical positioning; But the thrust of the clods on the receiving carriage is imprecise and causes not only a displacement of variable amplitude, but also overturns and even clod breakage, which makes them mostly unusable industrially.

 The device according to the invention eliminates these drawbacks and makes it possible to ensure automatic regulation of the translations by no longer using the thrust of the making machine, but only the weight of the clod or of the last row of clods to stop the translation at the exact location where the failure is to occur.

 It is constituted by the combination of a rocking tateur which by its displacement transmits with a rod, a push on a compass which by closing its angle attracts a driving roller against the receiving surface and causes its displacement.

In the accompanying drawings given by way of nonlimiting example of one of the embodiments of the subject of the invention
Figure 1 shows as a whole and in perspective view, the distributor control device.

 Figures 2 and 3 show some applications of the device.

 The clods advancing on the tongues 1, 2, 3, placed under the distribution grid 4 (Fia 2) are connected to the shaft 5 secured to the cam 6.

 On the lower part of the cam 6 is mounted the push rod 7 with counter-bending 8 and return spring 9 pressing on the fixed stop 10 forming a centering and balancing bearing.

 The end 11 of the pusher acts in the axis of the triggering compass whose arms 12 and 13 are connected on the one hand to the fixed point 14 and on the other hand to the shaft 15 supporting the drive roller 16 receiving its motor movement of the pinion 17 supported by the articulation rod 18 which makes the same movement. We therefore understand the operation of this device.

 In the pulling movement making it possible to free the receiving surface from the clod mat 19, arrow A, the released guardians 1, 2, 3 act on the compass 13, 14 to straighten it.

 The roller 16 is then no longer in contact with the surface 19. I1 occupies the position 16 '.

 On the other hand, when the empty surface 20 is put in place, the surface 19 takes the position 19 '(Fig 3), arrow B, and the clods advancing, present on the tongue. The latter by the rod 7 close the angle of the pusher and the rubber roller drives the bearing surface 19, arrow C, which is loaded.

 This alternating distribution accelerates production and makes it possible not to stop walking, arrow A.

 It is then possible to use a trolley 21 with a double cell capable of receiving the carrying surfaces 19. 20 and by moving them alternately, arrows BC, as and when they are filled, by lowering the stop screen 22 to avoid during the a few seconds required for the installation of packaging and distribution of clods.

During the displacements seen the stop of the distribution the roller occupies the position 16 'and no longer drives the surfaces 19 or 20.11 is further specified that when a crate is loaded and that the clods are separated, it is possible to pull the crate all the way back on its trolley to "disengage" the advancement and not move the empty crate which is waiting for its loading
However, the shapes, dimensions and arrangements of the various elements may vary within the limit of the equivalents, as moreover the materials used for their manufacture, without thereby changing the general conception of the invention which has just been described.
