Abstract:
A large round baler has a pickup including a tined reel mounted beneath an inlet at the bottom of an expansible baling chamber for picking up windrowed crop and delivering it into the inlet. The teeth of the tined reel are constructed so as to be in the neighborhood of at least two times stiffer than conventional teeth for the purpose of enhancing bale starting and diminishing plugging by effecting a constant smooth delivery of crop to the baling chamber. An embodiment is disclosed wherein ultra-stiff teeth, teeth which are so stiff as to be virtually inflexible, are used at selected areas across the width of the reel together with the stiff teeth.
Abstract:
An auger arrangement is provided to prevent the build-up of material on a belt support roll of a conveyor-like structure including a plurality of rolls supporting a plurality of belts thereon in side-by-side relationship and being configured to define the baling chamber of a round baler. The auger is mounted such that its flighting passes closely adjacent the outer surface of the roll from which it is desired that adhering material be removed to prevent the build-up of such material.
Abstract:
A large round baler is equipped with a pick-up and a feed fork apparatus which work together to gather crop from the ground and deliver it to the inlet of the bale forming chamber of the baler. The feed fork apparatus includes a plurality of teeth which are mounted to an eccentric located beneath a chute of the apparatus and are caused to sweep along an oval path in the direction of desired crop movement, the tines moving through respective slots provided in the chute. Leading edges of the tines are stair-stepped so that they engage the crop and carry it along the chute to the inlet to the bale forming chamber.
Abstract:
A large round baler includes mechanism for optionally wrapping a bale with either twine or a surface wrap material. A wrap control mechanism includes means whereby the wrapping process is initiated in response to a bale reaching a desired diameter within the bale chamber. Various microswitches are strategically mounted so as to be operated by various components of the twine and surface wrap mechanisms and the control mechanism therefor. These switches are integrated into an indicator circuit including indicator devices including various colored lights and a buzzer all of which are caused to operate in various modes to apprise an operator of when the wrapping process is beginning, whether or not twine or surface wrap material is present, when wrapping is complete and when the surface wrap material has been severed.
Abstract:
A baling machine for forming large cylindrical bales of hay has a gate which can be raised to an open position for enabling a completed bale to pass under it for discharge. Upon initial opening of the gate, the bale initially rests on a horizontal support which is connected by a cable and link to the gate. On the gate being raised further, the moving gate pulls the support via the cable and link so that it swings downwardly in a rearward direction to form a discharge ramp along which the bale may roll onto the ground and beneath that gate. The arrangement is such, however, that in hilly terrain the gate can be opened initially to an intermediate position corresponding to an intermediate swinging position of the support so that the bale runs down the support and either lodges against the gate before or after it contacts the ground. On either event the gate stops the bale from rolling. The gate is then raised further and the machine driven away from the bale which therefore does not have unwanted momentum derived from rolling down the support which would increase the tendency of the bale to roll too far over the sloping ground.
Abstract:
A baling machine, towed by a tractor, for forming large cylindrical bales of hay has a baling chamber defined by oppositely moving runs of belts trained over rolls.In order to avoid stray hay wrapping round the ends of one of the rolls supporting the belts and then being ingested in bearings supporting opposite ends of the roll, a scraper assembly is provided at each end of the roll. The assemblies each comprise a spiral which is welded to the roll and which moves the stray crop away from the end of the roll, and a scaper in light contact with the spiral preventing the crop being carried round the roll by the spiral. Possible crop buildup at the scraper in wet conditions is reduced further by an auger which is disposed just above the scraper and which is driven, e.g. by one of the belts, to move crop away from the scraper.
Abstract:
A press for forming large cylindrical bales includes a forward bale chamber for forming a bale core during the time a full sized bale located in a main bale chamber is being tied and discharged. A set of belts are mounted on a vertically shiftable roller so as to form a loop that delimits a rear portion of the forward chamber and a rear portion of the main chamber when the roller is in a lowered position and which is moved out of the way to permit a formed bale core to move from the forward chamber into the main chamber when the roller is in a raised position. In one embodiment a conveyor delimits the bottom of the forward chamber and cooperates with a first pickup to feed crop material to the forward chamber. A second pickup is arranged for delivering crop material directly into the main chamber. In a variant to the first embodiment a longer conveyor is used and the second pickup is omitted. The first pickup and longer conveyor cooperate to deliver crop material to the main chamber. In a second variant to the first embodiment, the conveyor and second pickup are omitted with a set of belts being arranged to delimit the bottom of the forward chamber and with the belt set loop and first conveyor being located for feeding crop material into the forward chamber when the shiftable roller is lowered and for feeding material to the main chamber when the roller is raised.
Abstract:
A round baler is provided having a web wrap apparatus with a feeder for introducing web into a bale chamber through a gap between adjacent motion means. The motion means are provided with protrusions, and anti-interference spacing means are provided to prevent the feeder from contacting the protrusions.
Abstract:
A combination is provided of an agricultural implement and vehicle. The implement includes components that can be driven that are connected to a power take-off shaft of the vehicle, the components being covered by at least one manually opened cover. A sensor is also provided to detect the open status of the cover, that is coupled to an electronic control unit of the implement. The electronic control unit, is connected with an electronic control unit of the vehicle. The electronic control unit of the implement instructs the electronic control unit of the vehicle in case of an opening of the cover detected by the sensor and advises an actuator to disengage a clutch of the power take-off shaft and/or to prevent the actuator from engaging the clutch.
Abstract:
A bale wrapper is provided that comprises a rotating arm holding a film dispenser. The arm rotates around an axis thereby wrapping the film from the film dispenser around the bale. Rotation of the arm is stopped when a sensing arrangement mounted ahead of the arm senses an obstacle. The arm is driven with a first speed sufficiently slow to prevent any risk of injury and the arm and the film dispenser from being damaged by hitting an obstacle detected by the sensing arrangement when an obstacle sensor observing a sensitive range in the environment of the bale wrapper detects an obstacle. The arm rotates at a second speed faster than the first speed when the obstacle sensor detects no obstacle.
