Definitions

  • the invention relates to a crop collecting device for harvesting machines.
  • Devices of this type are known in different designs. They are attached to the front part of a harvesting machine, for example a loading wagon, presses, forage harvesters or the like, and have a pick-up drum which runs approximately horizontally to the direction of travel and is provided with circumferential tines, the pick-up drum being often mounted on the machine frame of the harvesting machine. Designs are also known in which the harvesting machines have two rockers and which can be pivoted in height about a common pivot axis and extend forward and at the front end of which the receiving drum is mounted. It is often the case that the wings are inclined downwards.
  • the tines can also penetrate the turf and soil. This leads to increased travel and working resistance of the tines and thus to a downward moment acting on the swing arms. So that the penetration of the tines into the turf and / or the soil is further increased. Injuries to the turf and contamination of the crop with soil particles are unavoidable.
  • the drive power to be applied also increases
  • the object of the invention is to avoid these known disadvantages and to create with little effort a stalk crop pick-up device of the aforementioned type, in which the rake tines of the pick-up device pick up the crop cleanly even when the ground is uneven and excessive penetration into the turf and scratching of the ground is avoided.
  • the rake tines should adapt to the ground smoothly and automatically. So that the crop is picked up free of soil particles.
  • the machine load should be kept low and a light and economical design should also be possible. According to the invention, this is achieved in that the
  • 1 is a pick-up device with drive elements
  • Fig. 2 pushed a receiving device, with the front
  • FIG. 3 shows a receiving device with the push-button wheel pushed and the swivel axis lying at the front
  • Fig. 4 pushed a receiving device with a
  • Fig. 6 schematically shows a quadrangle. 7 a receiving device with a weight-reducing drive ratio of the receiving drum
  • Fig. 11 shows another recording device with Antri
  • Fig. 12 is a quadrangle with a swing arm for a
  • Fig. 1 shows a recording device from the side.
  • the swing arm 2 is approximately horizontal
  • Part of the rocker arm 2 has a receiving drum 26 rotatably mounted on its associated shaft 4.
  • the rake tines 5 are part of the take-up drum 26.
  • the drive gear 6 is mounted on the machine frame 1 and drives the gear 7, which is mounted concentrically to the pivot axis S1.
  • the sprocket 8 is rotatably connected to the gear 7.
  • the rescue 9 transmits the driving force from the larger sprocket 8 to the smaller sprocket 10, which is connected to the take-up drum 26 by this translation.
  • the sprocket 10 and the take-up drum 26 are driven with greater angular velocity in relation to the toothed and sprocket (7, 8) the consequence that the drive moment is weight-relieving on the rocker 2 and the take-up drum 26 and counteracts a downward moment that can arise in addition to the weight because the rockers 2 are inclined forward and pushed when the lower rake tines 5 scrape into the turf or the surface of the ground 11 or hit a child's ice if the floor is uneven or the setting is incorrect.
  • Swing arm 2 or the distance between the pivot axis S1 on shaft 4 determine the weight-relieving magnitude of the drive torque, because it determines how steep the traction strand of the chain 9 is in relation to the straight line of the swing arm 2. If the rake tines 5 have to overcome a greater resistance, the required drive torque and thus the weight relief increases, so that the receiving drum 26 with the rake tines 5 is automatically raised in the event of unforeseen obstacles and follows the course of the ground.
  • the drive transmission based on Machine frame 1, on the take-up drum 2b can take place in various ways over several gear stages, provided the weight is relieved.
  • the weight relief can be supported by means of the spring 13. Tracer wheels can also support ground adaptation.
  • the drive of the take-up drum 26 can also be provided on both sides. It is advantageous if the take-up drum 26 is divided.
  • Articulation points 12 two links 3 articulated on the machine frame 1 and extend forward and are articulated on the articulation 2 at further articulation points 12.
  • the handlebars 3 form with the machine frame 1 and the swing arm 2 a four-bar linkage.
  • the straight lines 19 of the links 3 intersect in the pivot axis S2, which represents the instantaneous pole of the four-bar linkage.
  • the receiving drum 26 and the rocker 2 can be pivoted about the ideal pivot axis 52 and which is also the ideal pulling point for the receiving drum 26 and lies in front of the shaft 4 and higher, like this.
  • the take-up drum 26 is pulled upward to relieve weight in the event of obstacles to be overcome by the rake tines 5 and can easily move around it and follow the same on a wavy ground surface 11, so that the rake prongs 5 maintain the desired distance from the ground surface 11.
  • the spring 13 also serves to relieve the weight.
  • Swivel axis S3 is pivotable by the handlebar 3 Establish the connection between the machine frame 1 and the rocker arm 2 via articulation points 12, thus forming a four-bar linkage 1, 2, 3.
  • the straight lines of the handlebars 3 intersect in the ideal swivel axis S3, which is behind the shaft 4 of the take-up drum 26 and the axis 14 of the feeler wheels 15 and deeper than this and below the floor surface 11.
  • the take-up drum 26 and the feeler wheel 15 are pressed upwards to relieve weight and can easily pivot about the ideal swivel axis S3 and upward with a greater resistance dodge and adapt to the ground.
  • the feeler wheel 15 is connected to the rocker 2a via the link 3 through the joints 13 to the machine frame 1 and can be pivoted about the ideal pivot axis S2.
  • the ideal swivel axis S2 lies in
  • link 3 establish the connection between the machine frame 1 and the rocker 2a. This creates a quadrilateral joint whose instantaneous pole represents an ideal swivel axis S3 for the feeler wheel 15 and the rocker 2a.
  • the web 16 connects the rockers 2a and 2 to one another, so that the take-up drum 26 follows the movements of the feeler wheel 15.
  • FIG. 6 shows a four-bar linkage which is formed by arcuate guideways 17 and sliding bodies or rollers 18 and whose path normal 19 intersect at the moment and determine an ideal swivel axis S at its intersection.
  • the guideways 17 can also be straight.
  • the rocker arm 2 is articulated on the machine frame 1 with the receiving drum so that it can pivot about the pivot axis S1.
  • the drive gear 6 drives the internal gear 20, which is arranged concentrically to the pivot axis S1, in the direction of rotation R.
  • the internal gear 20 meshes the gear 22 mounted on the rocker arm 2 and drives the same.
  • the sprocket 21 is rotatably connected to the gear 22 and drives the gear 10 of the take-up drum via the chain 9.
  • This configuration provides a weight-relieving moment on the rocker 2 about the pivot axis S1 during operation, which can be changed as a function of the drive torque to be applied and also increases when the working resistance acting on the rake tines 5 increases and the pick-up drum is raised and passed over an obstacle that may occur becomes. 8, the handlebars 3 have different lengths. With pivoting movements of the rocker 2a, the position of the ideal pivot axis S3 and thus the ideal thrust point for the feeler wheel 15 changes quickly.
  • Fig. 9 shows a four-bar linkage 1, -2, 3, 12 in which the handlebars 3 are articulated such that the rocker arm 2 crosses with the broken line 11 'of the machine frame 1.
  • the ideal pivot axis S3 also shifts upward.
  • the ideal swivel axis S3 lies below the axis 4 and above the floor surface 11.
  • the sprocket 24 according to FIG. 10 is arranged in such a way that the traction strand of the chain 9 runs steeper than the straight line of the rocker arm 2. This results in a good weight relief under load which can be reinforced if the sprocket 24 is arranged further up.
  • Fig. 11 shows a similar embodiment, but in which the sprocket 25 is provided for the drive.
  • Fig. 12 shows a four-bar linkage in which the handlebars 3 are subjected to tension in operation. This has the advantage that the rocker 2a adjusts itself automatically in the direction of travel F.
