Description

Technical Field

[0001] The utility model relates to the field of agricultural machinery, and particularly relates to an alarm device after the tying rope of a tying device of a semi-feed combine harvester is used up. Background Art

[0002] During the bale tying process of existing self-propelled balers, most balers are equipped with four bundles in two sets of tying ropes in the large rope box and two bundles in two sets of tying ropes in the small rope box. After use, there is no alarm device after the ropes are used up, and it is not easy for the operator to find that the tying ropes are used up, resulting in losses due to loose bales.

[0003] The Chinese patent authorization announcement number is CN 215345895 U, and the invention name is a tying rope breakage alarm device for a tying device of a semi-feed combine harvester, which discloses a tying rope breakage alarm device for a tying device of a semi-feed combine harvester, including a rope box, a tying rope roller is arranged in the rope box, an outlet hole for the rope is arranged on the outer wall of the rope box, and an alarm is further included. An induction torsion spring and an induction device connected to the alarm are fixedly connected to the outer wall of the rope box, and a pulling ring for the tying rope to pass through is arranged on the induction torsion spring. The technical solution of this combine harvester enables the adjusting rod to maintain stable contact with the induction device when the tying rope is used up. The adjusting rod hits the limit plate, so that the induction device receives the signal that the tying rope is disconnected, and the induction device thus controls the alarm to give an alarm. However, firstly, the structure is complex, and secondly, the tension of the spring rod is not easy to control, which is not practical. Summary of the Invention

[0004] The utility model provides an alarm device for a tying rope that is simple in structure and used up.

[0005] The technical solution of the present invention is that the synthesis route is as follows:

[0006] A rope shortage alarm device for a square self-propelled baler, which includes:

[0008] A rope shortage detection device for detecting the rope shortage state of the baler;

[0009] The alarm device and the rope shortage detection device are connected in series;

[0010] The rope shortage detection device is composed of a long rod swing arm limit micro switch and a relay in parallel;

[0011] Two tying rope terminals are connected to the long rod swing arm limit micro switch.

[0012] Furthermore, a button is provided on the circuit between the alarm device and the rope shortage detection device.

[0013] Further, the above alarm device is composed of a second relay and an audible and visual alarm in parallel.

[0014] Beneficial effects of the present utility model: The structure of the present utility model is simple, the alarm is accurate, and the installation is easy. Description of the Drawings

[0020] The present utility model will be further described below with reference to the drawings:

[0021] The following embodiments are further descriptions of the present utility model, rather than limiting the scope of the present utility model.

[0022] See Figure 1 , Figure 1 is a circuit schematic diagram of the rope - lacking alarm device of the self - propelled baler of the present utility model. The rope - lacking alarm device of the self - propelled baler is composed of a rope - lacking detection device 1, a button 2, and an alarm device 3 connected in series in the circuit. It is powered by the positive and negative poles of the storage battery; the first relay and the long - rod swing - arm limit micro - switch are connected in parallel and then connected in series with the button and the audible and visual alarm 3.

[0023] The rope - lacking detection device 1 is composed of a first relay and a long - rod swing - arm limit micro - switch connected in parallel in the circuit.

[0024] The alarm device 3 is composed of an audible and visual alarm and a second relay connected in parallel.

[0025] See Figure 2 Install the long - rod swing - arm limit micro - switch 1 of the rope detection device beside the rope box of the baler. Pull out two strands of ropes from the rope terminals of the baling ropes in the rope box and tie them to the upper end of the long - rod swing - arm limit micro - switch 1 of the detection device. The long - rod swing - arm limit micro - switch 1 has elasticity and can swing in any direction and reset automatically; its limit micro - switch can be of the YBLXW - 6 / 11W2 type.

[0026] Regardless of pulling off the terminal tying rope of the rope bundle 1 or the rope bundle 2, the long rod swing arm limit microswitch swings, the circuit is connected, and the sound and light alarm sounds continuously. Press the button switch to stop the alarm.

[0027] Specifically,

[0028] 1. The long rod swing arm limit microswitch is fixed on the fixed plate, and the fixed plate is fixed on the frame. The button, relay and sound and light alarm are fixed inside the side plate of the control room. Powered by the battery, the relay, long rod swing arm limit microswitch, button and sound and light alarm work in association with each other, as shown in Figure 1 .

[0029] 2. Pull out the terminal tying ropes of the rope bundles 1 and 2 from the rope bundle box respectively and tie them to the upper end of the long rod swing arm limit microswitch, as shown in Figure 2 .

[0030] 3. Regardless of pulling off any one of the terminal tying ropes (rope bundle 1 or rope bundle 2), the long rod swing arm limit microswitch starts to swing and contact, the circuit is connected, and the sound and light alarm starts to sound continuously. If the operation returns to normal, stop the machine immediately, replace the rope bundle, press the button switch, and after checking that the machine is normal, continue to work normally.
