Description

TECHNICAL FIELD

[0001] The utility model relates to a grain full sound and light alarm control system applied to agricultural machinery. BACKGROUND

[0002] The current grain full alarm system of the harvester is composed of a grain full sensor and a sound and light alarm, and some increase a switch in the line connected with the sound and light alarm to control the operation of the sound and light alarm. In the traditional grain full alarm system, when the grain in the granary is pressed to the grain full sensor circuit, the sound and light alarm is turned on to alarm, even if the user has known it, the alarm prompt cannot be turned off, which makes the user feel uncomfortable. Another grain full alarm system with a switch can turn off the noise at any time, but the user may forget to turn on the switch when harvesting again, which makes the system unable to work normally. The shell of the sound and light alarm is mainly yellow, and the yellow flicker is not obvious when it works. SUMMARY

[0003] The utility model aims at solving the above technical problems, and provides a grain full sound and light alarm control system applied to agricultural machinery.

[0004] The grain full sound and light alarm control system applied to agricultural machinery comprises a clutch, a clutch sensor, an alarm device and a grain full sensor. The clutch is used for controlling the operation of the harvester. The clutch sensor is used for sensing the state of the clutch and sending a state signal to the alarm device. The alarm device is used for alarming when the granary is full of grain. The grain full sensor is used for sensing the accumulation height of the grain in the granary. When the clutch is combined, the clutch sensor sends a first signal to the alarm device, and the alarm device works normally. When the clutch is separated, the clutch sensor sends a second signal to the alarm device, and the alarm device turns off the sound alarm.

[0005] Further, the alarm device is a sound and light alarm. The sound and light alarm comprises a transparent shell. The shell is internally provided with a light source. The shell is externally coated with a dark transparent film.

[0006] Further, the light source is yellow.

[0007] Advantages: Compared with the prior art, the clutch sensor senses the separation and combination state of the clutch and sends different signals to the alarm device, so as to control the sound alarm part of the alarm device to be turned off or turned on. The sound and light alarm only alarms when the harvester works to harvest grain, and does not alarm when the harvester starts but does not work to harvest grain, which reduces the noise of the sound and light alarm in the cab and the influence on the user. The light emitted by the sound and light alarm is more eye-catching through the dark transparent film. BRIEF DESCRIPTION OF DRAWINGS

[0012] In order to deepen the understanding of the utility model, the utility model will be further described in combination with examples and drawings below, and the examples are only used to explain the utility model and do not constitute a limitation on the protection scope of the utility model.

[0013] As shown in the figure, the clutch 1, the clutch sensor 2, and the sound and light alarm 3; Figs. 1-3

[0014] A grain full sound and light alarm control system applied to agricultural machinery, comprising a clutch 1, a clutch sensor 2, an alarm device, and a grain full sensor, wherein the clutch 1 is used for controlling the working of a harvester, the clutch sensor 2 is used for sensing the state of the clutch 1 and sending a state signal to the alarm device, the alarm device is used for issuing an alarm when the grain warehouse is full, and the grain full sensor is used for sensing the stock height of grain in the grain warehouse; when the clutch 1 is combined, the clutch sensor 2 outputs a first signal to the alarm device, and the alarm device normally works; when the clutch 1 is separated, the clutch sensor 2 sends a second signal to the alarm device, and the alarm device closes the sound alarm.

[0015] In the embodiment, the alarm device is a sound and light alarm, and the sound and light alarm 3 comprises a transparent shell, a light source is arranged in the shell, and a dark transparent film is arranged outside the shell.

[0016] In the embodiment, the light source is yellow.

[0017] Usage: the grain full sensor is connected with the alarm device; when the harvester works, the sound and light alarm 3 will issue an alarm after the grain is full, but whether the sound and light alarm 3 will issue a sound alarm is determined according to the signal sent by the clutch sensor 2; when the harvester clutch 1 is combined, the clutch sensor 2 sends a signal to the sound and light alarm 3, the sound and light alarm 3 normally works, that is, emits light and sound; when the harvester clutch 1 is separated, the clutch sensor 2 sends a high flat signal, and the sound and light alarm 3 closes the sound alarm, that is, only emits light; when the harvester does not work, the sound and light alarm 3 does not accept the signal.

[0018] ​The above merely describes preferred embodiments of the present application and is not intended to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
