The automatic control clutch is connected with an opening cylinder of the large round bale baler and comprises: a controller, a hydraulic cylinder, a block and a screw rod, a shift fork, a clutch outer sleeve, a clutch shaft sleeve, a driving sprocket and a chain. The controller sends an instruction to start or stop feeding grass according to a closing position signal or a full position signal of the opening cylinder. The hydraulic cylinder extends or retracts a piston rod according to the instruction to start or stop feeding grass. When the piston rod is extended, it pushes the screw rod to move, and the screw rod drives the block to deflect. The deflection of the block drives the shift fork to swing. The swing of the shift fork drives the clutch outer sleeve and the clutch shaft sleeve to slide on the driving shaft, so that the clutch shaft sleeve is combined with or disengaged from the driving sprocket on the driving shaft. When combined, the driving sprocket drives the clutch shaft sleeve and the driving shaft to rotate, and the driving shaft drives the conveyor belt to move to start feeding grass. When disengaged, the driving shaft stops rotating and the conveyor belt stops feeding grass, thereby realizing non-stop baling operation.

[0039] The controller is connected to a pressure sensor (not shown in the figure) in the warehouse opening cylinder, and the controller sends a command to start or stop sending grass according to a warehouse closing signal or a warehouse full signal sent by the pressure sensor.

[0040] In this embodiment, closing the bin in place means that the movable bin is closed after the straw bale is taken out of the bin.

[0041] The pressure sensor collects the pressure value in the opening cylinder in real time. When the pressure value reaches the upper limit, the pressure sensor sends a full-bin signal to the controller; when the pressure value reaches the lower limit, the pressure sensor sends a closing-bin signal to the controller.

[0042] In this embodiment, the controller is installed at the back end of a large round bale baler in a corn harvesting, green storage and yellow storage round bale baler.

[0043] The hydraulic cylinder 103 is fixed on the side wall of the large round baler. The hydraulic cylinder 103 includes a cylinder body 1031, an oil supply end 1032 and an oil return end 1033 arranged on the cylinder body 1031, and a piston 1034 and a piston rod 1035 arranged inside the cylinder body 1031 and connected to each other.

[0044] The oil supply end 1032 and the oil return end 1033 are both connected to the controller. The oil supply end 1032 obtains the oil supply pressure according to the start grass feeding instruction, and the oil supply pressure drives the piston 1034 to drive the piston rod 1035 to extend out of the cylinder body 1031; the oil return end 1033 obtains the oil return pressure according to the stop grass feeding instruction, and the oil return pressure drives the piston 1034 to drive the piston rod 1035 to retract into the cylinder body 1031.

[0045] The screw rod 105 passes through the stopper 104 , and the screw rod 105 is connected to the piston rod 1035 . When the piston rod 1035 is extended, it pushes the screw rod 105 to move, and the screw rod 105 drives the stopper 104 to deflect.

[0046] The shift fork 106 is a main component of the automatic control clutch, and the shift fork 106 is connected to the stopper 104 .

[0047] The shift fork 106 includes a movable portion 1061, a fixed portion 1062, and a support plate 1063 connecting the movable portion 1061 and the fixed portion 1062. The fixed portion 1062 is fixed on the stopper 104, and a rotating shaft sleeve 107 is fixed on the support plate 1063.

[0054] The shift fork 106 drives the clutch sleeve 109 to slide on the driving shaft 110 through the stop pin 1091 .

[0055] The stop pin 1091 of the clutch sleeve 109 is symmetrically welded on the outer wall. The stop pin 1091 slides in the U-shaped groove 10611 to compensate for the increase in the center distance between the small shaft 108 and the stop pin 1091 caused by the upward movement of the clutch sleeve 109 along the driving shaft 110 when the fork 106 swings.

[0056] The clutch sleeve 111 is connected to the clutch outer sleeve 109 , and the clutch outer sleeve 109 drives the clutch sleeve 111 to slide on the driving shaft 110 .

[0057] The inner hole of the clutch sleeve 111 is set as a single flat hole, and the corresponding single flat hole 116 and length are set at the matching position of the driving shaft 110 to ensure the sliding distance of the clutch sleeve 111 on the single flat hole 116 of the driving shaft 110. The clutch sleeve 111 transmits rotation and torque to the driving shaft 110 through the single flat hole 116.

[0058] The driving sprocket 112 is disposed on the driving shaft 110 , and the chain is respectively meshed with the driving sprocket 112 and an external power sprocket (not shown in the figure), and the external power sprocket drives the driving sprocket 112 to rotate through the chain.

[0059] The clutch sleeve 111 slides to the driving sprocket 112 and is coupled to the driving sprocket 112. In this embodiment, the coupling is meshing. At this time, the automatic control clutch is coupled, and the driving sprocket 112 drives the clutch sleeve 111 and the driving shaft 110 to rotate. The driving sprocket 112 drives the driving shaft 110 to rotate through the clutch sleeve 111. The driving shaft 110 drives the conveyor belt (not shown in the figure) to move, and grass is started to be delivered, thereby realizing the grass transport operation.

[0060] The clutch sleeve 111 is separated from the driving sprocket 112, the driving sprocket 112 is quickly disengaged from the clutch sleeve 111, and the conveyor belt stops conveying grass.

[0061] Symmetrical one-way meshing tooth grooves 115 are provided on one side of the clutch sleeve 111 that is combined with the driving sprocket 112 and on one side of the driving sprocket 112 that is combined with the clutch sleeve 111 .

[0062] The one-way meshing tooth groove 115 enables the clutch sleeve 111 and the driving sprocket 112 to quickly engage or disengage during movement, and transmits rotation and torque when engaged, while ensuring reliable engagement. The one-way meshing tooth groove 115 on the end surface of the clutch sleeve 111 and the driving sprocket 112 is a key structure, which requires reliable engagement during movement, reliable clutch engagement, and easy disengagement during movement, so that the clutch can be quickly released. The one-way meshing teeth are symmetrically designed on the end surface of the clutch sleeve, and the one-way meshing grooves are symmetrically designed on the matching end surface of the driving sprocket. After the clutch sleeve 111 is engaged with the driving sprocket 112, the clutch sleeve 111 and the single flat 116 cooperate to transmit rotation and torque to the driving shaft 110.

[0063] In order to ensure the stable operation of the automatic control clutch of the present invention, the automatic control clutch of the present invention further includes a block sleeve 113 and a bearing 114 .

[0064] The block sleeve 113 is connected to the fixing portion 1062 of the fork 106 , and the block sleeve 113 and the fixing portion 1062 are welded together. The block 104 is arranged in the block sleeve 113 , and the block 104 deflects along with the screw 105 in the block sleeve 113 , and the fixing portion 1062 passes through the block sleeve 113 and is connected to the block 104 .

[0065] The block sleeve 113 is also provided with a through slot 1131, and the screw rod 105 passes through the through slot 1131 and the block 104 at the same time. Fastening nuts (not shown in the figure) are provided on the screw rod 105 at both ends of the through slot 1031, and a set gap is provided between the fastening nuts and both ends of the through slot 1031, and the set gap is the distance that the screw rod 105 moves along with the piston rod 1035.

[0066] A flat portion 1132 is also processed on the outer wall of the block sleeve 113, and a through hole is processed in the middle of the block 104 to design a gap with the screw. After the block 104 is placed in the block sleeve 113, the screw 105 passes through the through groove 1131 and the through hole processed in the middle of the block.

[0067] The bearing 114 is disposed between the clutch sleeve 111 and the clutch outer sleeve 109 , and the bearing 114 enables the clutch sleeve 111 to rotate stably in the clutch outer sleeve 109 .

[0068] The clutch sleeve 109 cooperates with the clutch sleeve 111 through the bearing 114 to ensure that when the clutch sleeve 111 rotates, the shift fork 106 presses the clutch sleeve 109, the bearing 114, and the clutch sleeve 111, and the clutch sleeve 111 and the driving sprocket 112 remain combined.

[0069] When the clutch sleeve 111 is disengaged from the driving sprocket 112 , the driving sprocket 112 rotates idly in cooperation with the bearing 114 on the driving shaft 110 .

The piston rod 1035 pushes the screw 105 to move, and the screw 105 drives the block 104 to deflect. The deflection of the block 104 drives the shift fork 106 to swing around the small shaft 108, and the shift fork 106 drives the clutch sleeve 109, the bearing 114, and the clutch sleeve 111 to slide into the one-way meshing tooth groove 115 of the driving sprocket 112 through the stop pin 1091, and the clutch is automatically controlled to remain engaged. The clutch sleeve 111 obtains power and motion from the driving sprocket 112, thereby realizing the power and motion transmission between the clutch sleeve 111 and the driving sprocket 112.

[0077] When the grass feeding stops, the controller controls the solenoid valve to switch direction. The controller is connected to the hydraulic cylinder 103 through the fourth solenoid valve 510, the second solenoid valve 508 and the third solenoid valve 509, wherein the second solenoid valve 508 is connected to the oil supply end 1032 of the hydraulic cylinder 103, and the third solenoid valve 509 is connected to the oil return end 1033 of the hydraulic cylinder 103. When the controller issues a command to stop feeding grass, the fourth solenoid valve 510, the second solenoid valve 508 and the third solenoid valve 509 are energized, and the oil return end 1033 of the hydraulic cylinder 103 obtains the return oil pressure, and the cylinder is The cavity obtains hydraulic pressure, and the hydraulic pressure drives the piston 1034 to move and drive the piston rod 1035 to retract the hydraulic cylinder 103, and the piston rod 1035 drives the screw 105 to move, and the screw 105 drives the block 104 to deflect, and the deflection of the block 104 drives the shift fork 106 to swing around the small shaft 108, and the shift fork 106 drives the clutch sleeve 109, the bearing 114, and the clutch sleeve 111 to disengage the one-way meshing tooth groove 115 of the driving sprocket 112 through the stop pin 1091, and automatically controls the clutch to separate, the driving shaft 110 stops rotating, and the conveyor belt stops moving immediately, so that the grass delivery is stopped.

[0078] After the baler completes wrapping the bale with nets, counting its length, and cutting the nets, the movable bin is opened, and the bale slides out of the movable bin of the baler. After the movable bin is closed in place, the next grass feeding and baling cycle begins.
