Technical Field

[0001] The invention belongs to the technical field of agricultural machinery and equipment, and in particular relates to a knotting counter device, a knotting system and a knotting method. Background Art

[0002] Crop straw is a very valuable biomass energy resource in the agricultural ecosystem. The comprehensive utilization of crop straw resources is of great significance to promoting farmers' income, environmental protection, resource conservation and sustainable development of agricultural economy. With economic development and government support, in addition to the traditional method of crushing straw and replacing it as organic fertilizer, straw feed, straw gasification, straw power generation, straw ethanol, straw building materials and other fields have also been greatly developed.

[0003] Currently, the semi-feed balers used for baling crop straw on the market all have the knotter working at the rear of the harvester, so the driver cannot pay attention to the baling situation behind while driving, resulting in the rope running out without the driver's knowledge, the baler continues to work, the bales become loose, and the baling process cannot be carried out. Summary of the invention

[0029] The present invention will be described in more detail below in conjunction with the schematic diagram, wherein the preferred embodiment of the present invention is shown, and it should be understood that those skilled in the art can modify the present invention described herein, and still achieve the beneficial effects of the present invention. Therefore, the following description should be understood as being widely known to those skilled in the art, and not as a limitation of the present invention.

[0030] like Figure 1 As shown, a knotting counter device comprises three parts: a fixed frame 1, a torsion spring 2 and a retractable pressure sensor.

[0031] The fixing frame 1 comprises a first side surface, a second side surface and a third side surface which are connected in sequence.

[0032] The torsion spring 2 includes a fixed section, a coiled section and a swing section 21 connected in sequence; the fixed section is fixed to the inner side of the second side of the fixed frame 1, and the swing section 21 is located on the outer side of the fixed frame 1; one end of the swing section 21 away from the fixed section is coiled to form a rope hole 211 for the rope 8 to pass through. Preferably, an arc-shaped clamping arc is fixed on the swing section 21 for clamping with the pressure sensor body 3; the fixed section is perpendicular to the second side.

[0033] The pressure sensor includes a pressure sensing body and a housing 4; the housing 4 is fixed to the inner side of the first side of the fixed frame 1; the pressure sensor body 3 is installed on the housing 4 through an elastic mechanism; the pressure sensor body 3 extends out of the housing 4 and toward the outside of the fixed frame 1; the pressure sensor body is within the swing range of the swing section 21. Preferably, the elastic mechanism is a spring; the spring is fixed to the inner side of the housing 4.

[0034] like Figures 2~4 As shown, a knotting system includes the above-mentioned knotting counter device, a swing frame 5 and a rope drum 7.

[0035] The fixed frame 1 is fixed to the frame 6 .

[0036] The swing frame 5 is located at one side of the fixed frame 1 and is installed on the frame 6 via a rotating shaft. A channel 51 for the binding rope 8 to pass through is provided on the swing frame 5. An angle sensor for measuring the swing angle is provided on the rotating shaft.

[0037] The rope drum 7 is located at the other side of the fixed frame 1 . The rope drum 7 is rotatably disposed at the bottom of the frame 6 . The rope 8 is wound around the rope drum 7 .

[0038] The working principle of this knotting system is:

[0039] (1) Cordless state

[0040] Before use, the swing section 21 is separated from the pressure sensor body 3. Figure 2 As shown, when the swing angle of the swing section 21 measured by the angle sensor is the first swing angle, the first swing angle is the initial angle, that is, zero degree.

[0041] (2) Initial state

[0042] like Figure 3 As shown, one end of the tying rope 8 is passed through the rope hole 211 of the swinging section 21 and the channel 51 of the swinging frame 5 in sequence, and then the tying rope 8 is fixed to the channel 51; due to the tension of the tying rope 8 itself, the tying rope 8 drives the swinging section 21 to swing toward the pressure sensor body 3 until the swinging section 21 fits the pressure sensor body 3. The angle sensor obtains the swing angle of the swinging section 21 in real time. When the swinging section 21 fits the pressure sensor body 3, the angle sensor transmits the obtained second swing angle to the controller, and the alarm device and the counter do not operate.

[0043] (3) Knotted state

[0044] like Figure 4As shown, the swing frame 5 is started, and the swing frame 5 drives the rope 8 to swing upward to the set position; during the swinging process of the swing frame 5, the swing section 21 swings upward with the rope 8, and the pressure sensor body 3 is in contact with the swing section 21 and moves toward the housing 4. The angle sensor obtains the swing angle of the swing section 21 in real time. When the swing frame 5 drives the rope 8 to swing upward to the set position, the angle sensor transmits the obtained third swing angle to the controller, the alarm device does not work, and the counter counts once. Among them, the starting process of the swing frame 5 is a prior art and will not be repeated here.

[0045] During use, when there is no rope in the rope hole 211, the torsion spring 2 will eventually reset to the rope-free state (first swing angle state) under the action of its own elastic force. At the same time, since the angle sensor obtains the swing angle of the swing frame 5 in real time, when the angle sensor shows that the swing angle of the swing section 21 is back to the first swing angle, the angle sensor transmits a signal to the controller, and the controller feeds back a signal to the alarm device to perform an alarm process, so as to remind the operator to install the binding rope 8 in time to ensure normal operation of the machine.

[0046] The above is only a preferred embodiment of the present invention and does not limit the present invention in any way. Any technician in the relevant technical field, without departing from the scope of the technical solution of the present invention, makes any form of equivalent replacement or modification to the technical solution and technical content disclosed in the present invention, which does not depart from the content of the technical solution of the present invention and still falls within the protection scope of the present invention.
