Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of harvesting machines, in particular to a grain fullness reminding control circuit of a harvesting machine. BACKGROUND

[0002] The grain fullness alarm of a harvesting machine is a sensor or system installed on the harvesting machine to monitor the storage amount of grains in the grain bin. When the grains reach the preset upper limit, the alarm will sound, light or other forms of warning to remind the operator to empty the grain bin in time to prevent overflow or affect subsequent harvesting operations.

[0003] As disclosed in Chinese patent CN101755535A, a grain bin alarm on a harvesting machine capable of automatically displaying the grain storage condition in the grain bin; the grain bin alarm on the harvesting machine comprises a grain bin and an operation plate, characterized in that: one end of a sensing switch fixed in the grain bin is connected with one end of a relay coil, the other end of the sensing switch is connected with one end of a normally open contact of a relay, the other end of the normally open contact is connected with one end of a buzzer, the other end of the buzzer is connected with a zero line, and the other end of the relay coil is also connected with the zero line. One end of the sensing switch fixed in the grain bin is connected with one end of the relay coil, the other end of the sensing switch is connected with one end of the normally open contact of the relay, the other end of the normally open contact is connected with one end of an indicator lamp, the other end of the indicator lamp is connected with the zero line, and the other end of the relay coil is also connected with the zero line. When the grains in the grain bin are stored to the position of the sensing switch, the buzzer alarms, so that the driver can timely grasp the grain storage condition in the grain bin, prevent the grains from overflowing out of the bin, cause unnecessary losses, or timely transfer the grains in the grain bin, thereby improving the harvesting efficiency.

[0004] However, the existing grain fullness alarm of the harvesting machine is single, that is, after detecting that the grain bin is full, the grain fullness alarm starts to alarm. Since the noise of the harvesting machine is large during harvesting, the decibel of the grain fullness alarm is also large, so that after the grain fullness alarm is triggered, the grain fullness alarm alarms regardless of whether the harvesting machine is operated or not. Only after the grain is unloaded, the grain fullness alarm stops alarming, which leads to poor driving experience of the operator of the harvesting machine. SUMMARY

[0029] The control module 100 is the core processing unit of the scheme, and a chip integrated controller is used as the control module 100 in the scheme. The control module 100 also has a CAN communication interface. The control module 100 specifically includes a control chip. The AD0 pin and the AD1 pin of the control chip are respectively used to receive the grain full signal and the harvester operation signal. The VCC pin of the control chip is connected with a +12V storage battery of the power module. The A8 pin of the control chip is connected with a resistor R1. The other end of the resistor R1 is connected to the base of an NPN transistor Q1. The emitter of the NPN transistor Q1 is grounded. The collector of the NPN transistor Q1 is connected with a diode D1. The collector of the NPN transistor Q1 is connected to the positive electrode of the diode D1. The negative electrode of the diode D1 is connected to the +12V voltage of the VCC. The control module also includes a relay RL1. The 85 pin of the relay RL1 is connected to the VCC pin.

The power module 400 in the present application adopts a DC 12V battery as the power module 400, and the positive and negative poles of the battery are connected to the power input interface of the control module 100, and the negative pole is grounded for safety.

[0032] Referring to Figure 1 As shown, in some embodiments, the sensor module 200 specifically includes: a threshing handle sensor 210, one end of which is connected to the control module 100, and the other end is grounded.

[0033] Among them, the threshing handle sensor 210 is set as a switch quantity form sensor, and the threshing handle sensor 210 is set as a normally open state; when the threshing handle sensor 210 detects the harvester operation, the threshing handle sensor 210 is closed and sends the harvester operation signal to the control module 100.

[0034] Referring to Figure 1 As shown, in some embodiments, the sensor module 200 further includes: a full grain sensor 220, one end of which is connected to the control module 100, and the other end is grounded.

[0035] Among them, the full grain sensor 220 is set as a switch quantity form sensor, and the full grain sensor 220 is set as a normally open state; when the full grain sensor 220 detects that the grain bin is full, the full grain sensor 220 is closed and sends the full grain signal to the control module 100.

[0036] Referring to Figure 1 As shown, in some embodiments, the alarm module includes: a full grain alarm 310, one end of which is connected to the control module 100, and the other end is grounded.

[0037] Among them, when the control module 100 receives the harvester operation signal and the full grain signal at the same time, the control module 100 supplies power to the full grain alarm 310 and controls the full grain alarm 310 to perform the alarm operation; when only the harvester operation signal or the full grain signal is received, that is, the harvester is not operated or the grain bin is not full, the control module 100 does not supply power to the full grain alarm 310, so that the full grain alarm 310 remains quiet, thereby improving the driving experience of the operator during use, avoiding the corresponding negative emotions and physical effects of the operator during long-time operation of the harvester, and improving the efficiency.

[0038] Referring to Figure 1 As shown in some embodiments, the sensor module further comprises: an instrument 320 connected with the CAN channel interface of the control module 100.

[0039] When the control module 100 receives the harvester operation signal and the full grain signal at the same time, the control module 100 supplies power to the instrument 320 and controls the grain bin to display corresponding grain bin information.

[0040] Control principle: when the harvester is working, the threshing handle moves to make the threshing handle sensor 210 closed, and the control module 100 receives the threshing handle signal; when the grain bin is full, the full grain sensor 220 is closed, and the control module 100 receives the full grain signal, at this time the control module 100 outputs +12V power and sends CAN message signal to the instrument 320, so that the full grain alarm 310 is powered on and thus alarms; the instrument 320 displays the grain bin instrument 320 prompt information.

[0041] When the harvester stops working, the threshing handle does not move, the threshing handle sensor 210 remains open, and the control module 100 does not receive the threshing handle signal; at this time, when the grain bin is full, the full grain sensor 220 is closed, even if the control module 100 receives the full grain signal, the full grain alarm 310 will not alarm; only when the threshing handle sensor 210 closed signal is received, the full grain alarm 310 can be powered on and thus alarms; the instrument 320 displays the grain bin instrument 320 prompt information.

[0042] The present application can integrate the information of the sensor module 200 through the control module 100, and only when the harvester operation signal and the full grain signal are received at the same time, the alarm module 300 is controlled to alarm, so that the worker only needs to stop the harvester operation when the grain is full to cancel the alarm, thereby improving the working experience of the worker, and the alarm module 300 can also timely alarm when the grain is full and the worker drives the harvester to work, thereby reducing the grain bin overflow.
