Embodiment Construction

[0037] figure 1 The rear of an agricultural tractor 1 is shown attached to an agricultural sprayer 2 by a three-point connection, comprising two lower arms 3 and an upper arm 4 arranged to be connected to a connection 5 .

[0038] If the agricultural sprayer 2 is viewed from a closer viewpoint and without the presence of the tractor's three-point arm (see figure 2 ), then the situation and properties of the connecting device 5 can be more clearly understood. In the example shown, a device is shown consisting of two identical devices 5, 5' positioned in parallel at a distance from each other. The connecting device 5, 5' is fixed on the chassis 20 of the agricultural sprayer 2 by two pins, the first pin 6 of which can be seen.

[0039] from image 3 The complete connection device 5, 5' can be seen in , wherein there is a first pin 6 and a second pin 6', both of which are used to fix the connection device 5, 5' to the chassis 20 of the agricultural sprayer 2 (see figure 2 )...

Device for connecting an agricultural accessory to an agricultural tractor vehicle, comprising a lock actuation part, a connecting part and an arming member, wherein the coupling member of the agricultural vehicle actuates the pawl in order to effect a connecting, the said coupling member actuating the lock actuation part in order to lock the pawl and prevent the movement of the coupling member, and the said coupling member actuating the pawl once again and then the arming member in order to effect a disconnection and leave the device ready for a new connecting.

Description

technical field [0001] The present invention relates to the field of devices for connecting a suspended accessory to an agricultural vehicle, in particular a device for connecting a suspended agricultural sprayer to a suitable agricultural tractor. Background technique [0002] As the name suggests, the purpose of a farm sprayer is to spray liquid onto a crop field. The liquid is contained in a liquid tank supported on a chassis that is attached to a farm tractor for delivery of the sprayer. In general, agricultural sprayers include extensions, often referred to as "booms," which deliver the liquid to the greatest possible distance from the liquid tank to cover the greatest possible area of ​​the field at a time. Usually the liquid that is sprayed contains phyto-disease control products used to treat crops in order to prevent diseases or pests or the like. [0003] A suspended agricultural sprayer is characterized by being supported by the tractor in an elevated position r...
