Agricultural baler with remote bale length control
An agricultural baler includes a main bale chamber; a bale length sensor that is configured to determine a length of the bale as the bale is being formed in the main bale chamber and output a bale length signal representative of the bale length; a knotter that is configured to wrap and tie twine around the bale in the main bale chamber; and a controller that is configured to output a knotter cycle initiation signal to the knotter when the length of the bale, as determined in the controller by the bale length signal, reaches a pre-determined bale length threshold value, and wherein the knotter cycle initiation signal actuates the knotter to wrap and tie twine around the bale. A remote control device, which is remote from the baler, is configured to communicate with the controller to remotely adjust the pre-determined bale length threshold value.
1 . An agricultural baler comprising:
a main bale chamber in which crop material is compressed into bales, the main bale chamber comprising an inlet for receiving a wad of crop material from a pre-compression chamber of the agricultural baler, and an outlet for discharge of compressed crop material into a bale;
a bale length sensor that is configured to (i) determine a length of the bale as the bale is being formed in the main bale chamber and (ii) output a bale length signal that is representative of the bale length;
a knotter that is configured to wrap and tie twine around the bale in the main bale chamber;
a controller that is configured to output a knotter cycle initiation signal to the knotter when the length of the bale, as determined by the controller as a function of the bale length signal, reaches a pre-determined bale length threshold value, and wherein the knotter cycle initiation signal actuates the knotter to wrap and tie twine around the bale; and
a remote control device, which is remote from the baler, that is configured to communicate with the controller to remotely adjust the pre-determined bale length threshold value, wherein the remote control device is a controller of another baler,
wherein the controller is configured to output one or more baler status signals to the remote control device, wherein the one or more baler status signals comprise the pre-determined bale length threshold value, the bale length signal, and a crop moisture reading.
2 . The agricultural baler of claim 1 , wherein the bale length sensor is a rotatable 2 . star-wheel that is mounted in the main bale chamber.
3 . The agricultural baler of claim 2 , wherein the bale length sensor further comprises a rotary encoder that is operatively coupled to the star-wheel, the rotary encoder being configured to output rotation signals to the controller corresponding to a rotation of the star-wheel.
4 . The agricultural baler of claim 3 , wherein the controller is configured to calculate the length of the bale based on the output rotation signals of the rotary encoder.
5 . The agricultural baler of claim 1 , wherein the remote control device is physically disconnected from the controller.
6 . The agricultural baler of claim 1 , wherein the remote control device is a mobile device including a processor.
7 . The agricultural baler of claim 6 , wherein the mobile device is a tablet computer, or a laptop.
8 . The agricultural baler of claim 1 , wherein the controller includes a wireless fidelity (WiFi) module, a mobile telephony module and/or a BLUETOOTH® module to enable communications with the remote control device.
9 . The agricultural baler of claim 1 , wherein the remote control device includes a cellular network that outputs a bale length adjustment signal to the controller after being prompted by one or more devices coupled to the cellular network.
10 . The agricultural baler of claim 1 , wherein the remote control device includes a graphical user interface that is programmed to display data relating to the baler status signals.
11 . The agricultural baler of claim 1 , wherein the controller is configured to output one or more bale length adjustment signals to controllers of other balers in a vicinity of the baler.
12 . The agricultural baler of claim 1 , further comprising a plunger that is configured for compressing the crop material within the main bale chamber.
13 . An agricultural vehicle comprising the agricultural baler of claim 1 .
14 . The agricultural baler of claim 1 further comprising a memory for storing the pre-determined bale length threshold value such that the pre-determined bale length threshold value is employed for successive bales yielded by the agricultural baler.
