[0102] The control system 200 of the bale press mechanism of the cotton picker includes the following working process:

[0103] The bale press process: the bale forming chamber is in a cavity state, the flow of the oil circuit in which the fixed swing arm drive cylinder 102 and the movable swing arm drive cylinder 202 are located is controlled through the multi-way valve 9, and the pulling force of the fixed packing belt 103 and the movable packing belt 203 is restricted through the first overflow valve 5 and the second overflow valve 8, so as to determine the bale density of the cotton bale 12.

[0104] The opening and unloading process: when the fixed swing arm drive cylinder 102 and the movable swing arm drive cylinder 202 reach the maximum stroke and the bale press process is completed, the multi-way valve 9 is switched to a non-working position, and the fixed swing arm drive cylinder 102 and the movable swing arm drive cylinder 202 are in a locked state, so that the movable box 2 rotates smoothly to open the bin and unload the bale.

[0105] Combining process: after opening and unloading the bale, the fixed packing belt 103 and the movable packing belt 203 are in a loose state, the multi-way valve 9 is switched to the working position, the flow of the oil circuit in which the fixed rocker arm driving oil cylinder 102 and the movable rocker arm driving oil cylinder 202 are located is controlled, the fixed rocker arm driving oil cylinder 102 and the movable rocker arm driving oil cylinder 202 are reset, the combining is completed, and when the combining is completed, the movable box 2 returns to the initial state.

[0106] The control system 200 of the bale packaging mechanism of the cotton picker can adjust the working state of the control system 200 according to specific packaging requirements, so as to meet different working conditions.

[0107] In the embodiment, the bale packaging mechanism 100 and the control system 200 thereof include three stages in one working cycle: a packaging process, an opening and unloading process, and a combining process, and one complete working cycle in time sequence is as follows:

[0108] The packaging process: in the initial state, the bale forming chamber is in a cavity state, the seed cotton is fed through the channel between the first fixed guide roller 111 and the fourth movable guide roller 211, and at this time, the first movable guide roller 208 and the first fixed guide roller 111 start to operate as driving rollers. At the same time, the gear pump 6 of the control system 200 starts to work, the oil enters the P port of the multi-way valve 9 through the gear pump 6, and the multi-way valve 9 controls the flow of the two paths according to the predetermined setting ratio. In this process, the first overflow valve 5 and the second overflow valve 8 respectively constrain the tension of the fixed packing belt 103 and the movable packing belt 203 (the setting pressure of the first overflow valve 5 is greater than that of the second overflow valve 8) to determine the bale density of the bale 12, and the pressure indicator 4 can respectively transmit the oil pressure signals in the fixed rocker arm driving oil cylinder 102 and the movable rocker arm driving oil cylinder 202 to the cab of the cotton picker, and the driver can judge whether there is an abnormality in the packaging according to the oil pressure change.

[0109] The opening and unloading process: when the fixed rocker arm driving oil cylinder 102 and the movable rocker arm driving oil cylinder 202 reach the maximum stroke, the packaging process is completed, at this time, the multi-way valve 9 is switched to the middle position (the oil enters the P port, the oil outlet is T, and the oil is returned through the oil cooler 10 and the oil filter 11), and the fixed rocker arm driving oil cylinder 102 and the movable rocker arm driving oil cylinder 202 are in the locked position, so as to ensure that the movable box 2 is smoothly opened and unloaded.

[0110] The closing process: after the opening and unloading of the bale, the fixed packing belt 103 and the movable packing belt 203 are in a loose state, when closing, the multi-way valve 9 is switched to the working position. In order to make the packing belt in a taut state during the closing process, the controller 3 outputs continuous analog voltage signals V1 and V2 to the multi-way valve 9, which respectively controls the flow of the two oil ways (the oil way where the fixed rocker arm driving oil cylinder 102 is located and the oil way where the movable rocker arm driving oil cylinder 202 is located) of the multi-way valve 9 according to the signal change law, so that the flow of the two oil ways changes continuously at a non-uniform speed according to the predetermined voltage signal, and then the stroke S2(t) of the fixed rocker arm driving oil cylinder 102 and the stroke S1(t) of the movable rocker arm driving oil cylinder 202 change continuously at a non-uniform speed according to the predetermined law. When the closing process is completed, the movable box 2 is in the initial state, and the piston rods of the fixed rocker arm driving oil cylinder 102 and the movable rocker arm driving oil cylinder 202 are completely retracted.

[0111] The cotton picker packing mechanism 100 and the control system 200 thereof of the present application, when working, with the feeding of cotton, the fixed rocker arm 101 swings counterclockwise, the movable rocker arm 201 swings clockwise, the fixed packing belt 103 and the movable packing belt 203 rotate clockwise respectively, and the movable rocker arm 201, the fixed rocker arm 101, the fixed packing belt 103 and the movable packing belt 203 jointly act on the cotton bale 12 to form a round bale cotton bale 12 with uniform density. The present application realizes independent control of the fixed rocker arm driving oil cylinder 102 and the movable rocker arm driving oil cylinder 202 by using the multi-way valve 9 to control the flow distribution, so that the movable packing belt 203 and the fixed packing belt 103 work independently. Compared with the packing system of the prior art with one packing belt, the present application can reduce the stretching and contraction amount of the packing belt during packing work, prolong the service life, and effectively ensure the uniformity of the density of the cotton bale 12.
