Definitions

  • the invention concerns a cutter press of the type defined in the introductory portion of claim 1.
  • a cutter press can pick up cut crops lying on the ground, cut them and compress them to bales which, either tied with twine by means of a tying mechanism or wrapped in plastics by means of a mechanism adapted for the purpose, are deposited in the field-
  • Hydraulic presses are known, e.g. from the DE Patent Specifications 3 809 131 and 3 809 132, which are equipped with a very big prechamber for the material picked up and a rather complicated mechanical device moving the material from the prechamber to the compressing chamber when the plunger has been retracted.
  • the object of the invention is to provide a cutter press of the present type whose compressing section is simpler and more inexpensive to produce than the known ones, while working more efficiently.
  • the cutter press is constructed as stated in the characterizing portion of claim 1, since, in this structure, the feed channel and the inlet channel telescopically connected with the feed channel form a variable prechamber which is much smaller than in the known process, and which makes special transport means completely superfluous.
  • Claim 3 defines an embodiment with a hydraulic cylinder assisting the material pressure generated by the feed drum inlifting the compressing chamber.
  • the hydraulic pressure in this cylinder is adjustable and thus adapted that it only takes a moderate pressure in the material in the prechamber and the compressing chamber to lift it slightly, thereby activating the compressing plunger to perform a stroke.
  • the invention also concerns a method in the making of bales with the stated cutter press, and the unique features of the method of the invention are defined in claim 9.
  • fig. 1 is a schematic vertical section through an embodiment of the cutter press of the invention.
  • fig. 2 is a side view of such a cutter press with mounted wrapping equipment and discharge slot.
  • the main fram carries an assembly consisting of a pickup 12, which picks up the material from the ground, and a feed drum 13, which receives the material from the pickup and moves it past cutters 14 up into a feed channel 15.
  • This assembly 12-16 is driven mechanically from the tractor by known means (not shown).
  • the material is pressed from the feed channel 15 up into compressing chamber 17, which is pivotably journalled at the rear end on the main frame 10 by means of a shaft 18.
  • the compressing chamber In the vicinity of the front end the compressing chamber has an inlet opening 19 and an inlet channel 20 which is arranged opposite the inlet opening and whose walls surround and are telescopically movable with respect to the feed channel 15.
  • a compressing plunger 21 is slidably mounted in the front end of the compressing chamber 17, said compressing plunger being connected partly with a hydraulic drive cylinder 22, partly with a closing plate 23 which is slidable along the bottom of the compressing chamber and closes the inlet opening 19 during the greater part of the plunger movement.
  • the underside of the plunger mounts a rearwardly directed knife 24 which cuts free the material pressed up into the compressing chamber during the compressing movement of the plunger.
  • a hydraulic cylinder 25 is rotatably connected with the front end of the compressing chamber 17 at 26, and the plunger rod of the cylinder is rotatably connected with the main frame 10 at 27.
  • the compressing plunger 21 is shown in its retracted position in the drawing, and a plurality of compressed portions of material 28, produced by preceding plunger strokes, are shown in the compressing chamber 17.
  • the feed drum 13 presses cut material up into the compressing chamber part K positioned between the plunger and front portion of material.
  • the pressure from the drum 13 tries to lift the front end of the compressing chamber 17, i.e. pivot it about the pivot shaft 18.
  • the hydraulic pressure in the cylinder 25 is adjustable and so adapted that it only takes a moderate pressure in the chamber K from the feed drum 13 to lift the compressing chamber slightly.
  • a switch (not shown) is activated, causing the plunger 21 to perform a stroke, i.e.
  • Tying of the bales can be performed in a known manner by means of needles arranged on hydraulically activated swing arms 31, and the knotter mechanism 32 when the plunger 21, whose compressing face is formed with grooves (not shown) for the passage of the needles, is in its extreme position.
  • All the functions of the compressing section are carried out hydraulically with oil from the tractor or from a separate pump on the cutter press via a hydraulic system (not shown), which is capable of controlling the pressure of the material in the compressing chamber in a known manner, as desired.
  • a hydraulic system (not shown), which is capable of controlling the pressure of the material in the compressing chamber in a known manner, as desired.
  • the most compact bales are achieved when the pressure is kept at a maximum value for a certai time of the order of one to a few seconds at the termi ⁇ nation of each compressing stroke. However, this advantag is obtained at the expense of the time it takes to make a bale.
  • a less time-consuming, but still efficient method consists in maintaining the maximum pressure for a period of time after the termination of each of the compressing strokes completing the compression of a bale.
  • the plunger rate can advantageously be varied, and it will generally be expedient to control the oil pressure such that the plunger initiates both the compressing stroke and the return stroke at a high speed and terminates at a low speed.
  • the controlling parameter of the hydraulic system may e.g. be the output signal from a bale measuring wheel or from a counter mechanism or the like.
  • the amount of material left in the prechamber Q at the termination of the operation is moved up into the compressing chamber by means of a sector 34 fitted on a rotatable shaft 33, said sector consisting of a plurality of parallel plates which, upon rotation of the shaft, protrude into slots in the walls of the feed channel 15 and the inlet channel 20 facing the shaft.
  • This sector 34 is operated by a hydraulic cylinder (not shewn).
  • a cutter press according to the invention is shown with mounted equipment for automatic wrapping of the bales in plastics bags.
  • the equipment consists of a feed roll 35 mounted above the rear part of the compressing chamber and on which there is wound a carrier band 36 with four-sided openings corresponding to the cross-section of the compressing chamber and with the edges of folded plastics bags 37 attached along the edges of the openings, as well as of a roll 38 arranged below the compressing chamber to receive the carrier band freed of bags.
  • the • rear end of the main frame 10 mounts an inclined rolling chute 39 along which the wrapped bales 40 can slide down on to the ground.
  • the compressing chamber may optionally be parallel-slidable instead of piv ⁇ table.

Abstract

Dans une presse coupante comportant un bâti (10) portant un dispositif ramasseur-chargeur (12) et un tambour d'alimentation (13) coopérant avec des lames coupantes (14) ainsi qu'une chambre de compression (17) équipée d'un piston de compression (21) et recevant le matériau coupé transmis par le tambour, la chambre de compression est montée rotative sur paliers (18) par son extrémité arrière sur le bâti. Le tambour (13) introduit le matériau dans un canal d'alimentation fixe (15) et la chambre de compression (17) possède une ouverture d'entrée (19) située sur son extrémité avant et un canal d'entrée (20) qui est placé en face de ladite ouverture et entoure le canal d'alimentation (15) de façon télescopique. Quand la chambre (K) située dans la chambre de compression entre le piston et le matériau déjà comprimé, est pleine, la pression du matériau provenant du tambour élève l'extrémité avant de la chambre de compression, avec l'aide d'un vérin hydraulique (25), ce qui augmente le volume de la préchambre (Q) formée par le canal d'alimentation et le canal d'entrée, pour que le tambour d'alimentation puisse continuer à introduire le matériau dans ladite préchambre, tandis que le piston de compression effectue une course et ferme l'ouverture d'entrée (19).
