[0002] Girdling refers to the practice of removing a certain width of bark around the stem of a plant. In tobacco cultivation, timely and appropriate girdling can block the downward transport of nutrients through the phloem, which is conducive to the accumulation of photosynthetic products in the leaves, accelerates the ripening and yellowing of tobacco leaves, and improves the quality of tobacco leaves.

[0003] Existing girders consist of a hinged first clamp and a second insert, both with blades mounted in their center. The blades are connected by a cylinder and bolts. The blade angle can be adjusted to control the girdling depth. By manually driving the relative movement of the first and second inserts, the blades are used to girdle tobacco of different diameters. However, this operation is not only laborious but also only allows for a single mode of full-circumference cutting, making it impossible to gradient control the cutting ratio of the tobacco phloem, resulting in poor flexibility and adaptability in girdling.

[0031] Please refer to Figure 1 This embodiment provides a girder 100, including a drive assembly and a first insert 120 and a second insert 130 disposed opposite to each other. The first insert 120 and the second insert 130 can enclose to form a clamping space for holding the object to be girdled. A first blade 140 is slidably disposed on the inner side of the first insert 120, and a second blade 150 is slidably disposed on the inner side of the second insert 130. The drive assembly is used to synchronously drive the first blade 140 and the second blade 150 to slide. The drive assembly outputs at least a first driving force and a second driving force. The first driving force drives the first blade 140 and the second blade 150 to slide a first preset stroke, respectively. The second driving force drives the first blade 140 and the second blade 150 to slide a second preset stroke, respectively. The second preset stroke is greater than the first preset stroke.

[0032] Specifically, such as Figure 1As shown, the ring cutter 100 includes a first insert 120 and a second insert 130. Both the first insert 120 and the second insert 130 are arc-shaped structures, symmetrically arranged to form a ring-shaped clamping structure. When the first insert 120 and the second insert 130 are closed, a circular or arc-shaped space adapted to the tobacco stem is formed on the inner side, thereby conforming to the circular outline of the tobacco stem and improving clamping stability. A first blade 140 is provided on the inner side of the first insert 120, and a second blade 150 is provided on the inner side of the second insert 130. The drive assembly is used to provide driving force for the first blade 140 and the second blade 150. The drive assembly can drive the movement of the first blade 140 and the second blade 150 by electric drive, pneumatic drive, etc. This application does not limit the specific driving method of the drive assembly. In a preferred embodiment of this application, the drive assembly drives the movement of the first blade 140 and the second blade 150 by electromagnetic drive. Compared to the traditional method of manually driving the blades to girdle tobacco stalks, the design of the drive component reduces labor consumption and solves the problem of laborious manual girdling in existing technologies, making it particularly suitable for continuous operations in large-scale tobacco planting scenarios.

[0033] The drive assembly has different drive gears, and different drive gears can drive the first blade 140 and the second blade 150 to move different strokes. In this application, the drive assembly outputs at least a first drive force and a second drive force. The first drive force drives the first blade 140 and the second blade 150 to slide a first preset stroke, and the second drive force drives the first blade 140 and the second blade 150 to slide a second preset stroke, wherein the second preset stroke is greater than the first preset stroke.

[0034] This application does not impose any restrictions on the specific travel amounts of the first preset travel and the second preset travel. Preferably, the first preset travel is a quarter-distance that the first blade 140 slides along the inner side of the first insert 120, while the second blade 150 slides along the inner side of the second insert 130. The second preset travel is a distance that the first blade 140 slides along the inner side of the first insert 120 from one end to the other, that is, the first blade 140 slides the entire inner side of the first insert 120; at the same time, the second blade 150 slides along the inner side of the second insert 130 from one end to the other, that is, the second blade 150 slides the entire inner side of the second insert 130.

[0035] Of course, the above is only a preferred embodiment of this application. The first preset stroke and the second preset stroke can be adjusted according to the actual plant growth needs and the purpose of girdling, as long as the flexibility and adaptability of the girdling cutting ratio are guaranteed.

[0036] To further improve the flexibility of girdling, in one embodiment of this application, the drive component can also output a third driving force, which drives the first blade 140 and the second blade 150 to slide a third preset stroke, respectively; the third preset stroke is located between the first preset stroke and the second preset stroke. Similarly, this application does not impose any limitation on the specific stroke amount of the third preset stroke.

[0037] In a preferred embodiment of this application, the first preset stroke is a quarter-distance sliding of the first blade 140 along the inner side of the first insert 120, and simultaneously a quarter-distance sliding of the second blade 150 along the inner side of the second insert 130; that is, when the first insert 120 and the second insert 130 are closed to form an annular clamping ring, the first preset stroke causes the first blade 140 and the second blade 150 to move a quarter turn within the annular clamping ring; the second preset stroke is the first blade 140 sliding along the inner side of the first insert 120 from one end... The first blade 140 slides to the other end while the second blade 150 slides along the inner side of the second insert 130 from one end to the other. In other words, the second preset stroke causes the first blade 140 and the second blade 150 to move a full circle within the annular clamping ring. The third preset stroke is formed by the first blade 140 sliding half a distance along the inner side of the first insert 120 while the second blade 150 slides half a distance along the inner side of the second insert 130. In other words, the third preset stroke causes the first blade 140 and the second blade 150 to move half a circle within the annular clamping ring.

[0038] It should be noted that, firstly, in one possible embodiment of this application, in order to facilitate flexible adjustment of the size of the annular clamping space enclosing the first insert 120 and the second insert 130 to adapt to tobacco stems of different diameters and further improve the circumferential fit of the tobacco stems, the ends of the first insert 120 and the second insert 130 are connected by a hinge shaft. The hinge shaft is located on the same side of the ends of the first insert 120 and the second insert 130, so that the first insert 120 and the second insert 130 can rotate around the hinge shaft as the rotation center, and quickly complete the clamping and release of tobacco stems of different diameters.

[0039] Second, such as Figure 1 As shown, in one possible embodiment of this application, the girder 100 further includes a first handle 160 connected to the first insert 120 and a second handle 170 connected to the second insert 130; driving the first handle 160 and the second handle 170 to move relative to each other causes the first insert 120 and the second insert 130 to rotate about a hinge axis respectively. By gripping the first handle 160 and the second handle 170 to apply force, the operator can easily control the rotation of the first insert 120 and the second insert 130 about the hinge axis, thereby achieving the opening and closing action.

[0040] Furthermore, such asFigure 1 As shown, to prevent the ring cutter 100 from slipping out of the hand, anti-slip sleeves 180 are fitted on the outer walls of the first handle 160 and the second handle 170. Preferably, the surface of the anti-slip sleeve 180 is provided with a textured surface to increase the coefficient of friction between the hand and the first handle 160 and the second handle 170, reducing the possibility of the ring cutter 100 slipping out of the hand when the operator squeezes and releases the handles to control the opening and closing of the first insert 120 and the second insert 130, thereby improving work efficiency.

[0041] The aforementioned girder 100 includes a drive assembly and a first insert 120 and a second insert 130 disposed opposite to each other. The first insert 120 and the second insert 130 can enclose and form a clamping space for girdling the object to be girdled, so that the girder 100 is stably fixed to the outer periphery of the object to be girdled, ensuring accurate relative position between the tool and the object to be girdled during the girdling process. A first blade 140 is slidably disposed on the inner side of the first insert 120, and a second blade 150 is slidably disposed on the inner side of the second insert 130. The drive assembly is used to synchronously drive the first blade 140 and the second blade 150 to slide. Through this arrangement... This design improves the flexibility of girdling. By adjusting the sliding stroke of the blades, different girdling requirements can be met, such as controlling the cutting ratio of the tobacco phloem. The drive component outputs at least a first driving force and a second driving force. The first driving force drives the first blade 140 and the second blade 150 to slide a first preset stroke, respectively; the second driving force drives the first blade 140 and the second blade 150 to slide a second preset stroke, respectively. The second preset stroke is greater than the first preset stroke. This design significantly reduces the labor intensity of operators and improves the efficiency of girdling operations. The different driving force outputs provide more choices and flexibility for girdling operations. In practical applications, for different growth stages, different varieties of tobacco, or different girdling purposes, the appropriate drive gear can be selected as needed. This setting allows for gradient control of the girdling cutting ratio. Compared to existing girders that can only achieve full-circumference cutting in a single mode, the girder 100 provided in this application can improve adaptability to diverse planting needs. The above-mentioned girder 100 is convenient and labor-saving to operate, and can gradient control the cutting ratio of the tobacco phloem, thus improving the flexibility and adaptability of girdling.

[0042] In one possible implementation of this application, such as Figure 2 and Figure 3As shown, the drive assembly includes a power supply unit 111, a first magnetic coil 112, and a second magnetic coil 113. The first magnetic coil 112 is disposed at the end of the first insert 120, and the second magnetic coil 113 is disposed at the end of the second insert 130. The power supply unit 111 is electrically connected to the first magnetic coil 112 and the second magnetic coil 113 respectively. The power supply unit 111 energizes the first magnetic coil 112 and the second magnetic coil 113 respectively, so that the first magnetic coil 112 and the second magnetic coil 113 generate attraction magnetic force respectively, thereby driving the first blade 140 to move toward the first magnetic coil 112 and the second blade 150 to move toward the second magnetic coil 113.

[0043] Specifically, such as Figure 2 and Figure 3 As shown, a first magnetic coil 112 is installed on one side of the first insert 120, and a second magnetic coil 113 is installed on one side of the second insert 130. The first magnetic coil 112 and the second magnetic coil 113 are respectively connected to the power supply unit 111 via wires. When the power supply unit 111 supplies power, the first magnetic coil 112 and the second magnetic coil 113 generate an attractive magnetic force, driving the first blade 140 and the second blade 150 to move, thereby realizing the circumferential cutting action. This electromagnetic drive method makes the operation convenient and labor-saving, while also ensuring the stability and controllability of the power output.

[0044] Optionally, such as Figure 2 and Figure 3 As shown, the first blade 140 is disposed at the end of the first insert 120 away from the first magnetizing coil 112 via the first elastic member 114; when the first blade 140 moves toward the first magnetizing coil 112, the first elastic member 114 stretches and stores energy; when the first magnetizing coil 112 is de-energized, the first elastic member 114 releases energy and drives the first blade 140 to reset; the second blade 150 is disposed at the end of the second insert 130 away from the second magnetizing coil 113 via the second elastic member 115; when the second blade 150 moves toward the second magnetizing coil 113, the second elastic member 115 stretches and stores energy; when the second magnetizing coil 113 is de-energized, the second elastic member 115 releases energy and drives the second blade 150 to reset.

[0045] Specifically, such as Figure 2 and Figure 3 As shown, one end of the first elastic member 114 is fixedly connected to the end of the first insert 120 away from the first magnetic coil 112, and the other end is connected to the first blade 140. The first blade 140 has a first cutting head 141 protruding from the side facing the first insert 120, and the first cutting head 141 is embedded in the first insert 120; the first elastic member 114 can be connected to the first cutting head 141, thereby avoiding interference with the cutting action of the first blade 140.

[0046] When the first magnetizing coil 112 is energized and generates an attractive magnetic force, the first blade 140 is driven to slide towards the first magnetizing coil 112. At this time, the first elastic element 114 is stretched by the first blade 140 and stores energy. When the first magnetizing coil 112 is de-energized, the attractive magnetic force disappears. At this time, the first blade 140 is no longer driven to slide towards the first magnetizing coil 112; the first elastic element 114 is no longer stretched and releases energy, causing the first blade 140 to return to its original position.

[0047] Similarly, as Figure 2 and Figure 3 As shown, one end of the second elastic member 115 is fixedly connected to the end of the second insert 130 away from the second magnetic coil 113, and the other end is connected to the second blade 150. The second blade 150 has a protruding second cutting head 151 on the side facing the second insert 130, and the second cutting head 151 is embedded in the second insert 130; the second elastic member 115 can be connected to the second cutting head 151, thereby avoiding interference with the cutting action of the second blade 150.

[0048] When the second magnetizing coil 113 is energized and generates an attractive magnetic force, the second blade 150 is driven to slide towards the second magnetizing coil 113. At this time, the second elastic element 115 is stretched by the second blade 150 and stores energy. When the second magnetizing coil 113 is de-energized, the attractive magnetic force disappears. At this time, the second blade 150 is no longer driven to slide towards the second magnetizing coil 113; the second elastic element 115 is no longer stretched and releases energy, causing the second blade 150 to return to its original position.

[0049] Preferably, the first elastic element 114 and the second elastic element 115 are springs.

[0050] By setting the first elastic element 114 and the second elastic element 115, the first blade 140 and the second blade 150 can be automatically reset. After the girdling is completed, the operator does not need to manually adjust the position of the first blade 140 and the second blade 150. Especially in large-scale tobacco girdling operations, the time cost of repeated operations can be reduced and the continuous operation capability can be improved.

[0051] For example, such as Figure 2As shown, the power supply unit 111 includes a battery 1112 and a ring-cutting switch 1113; the battery 1112 is installed in the battery compartment 1111; the ring-cutting switch 1113 is electrically connected to the battery 1112, the first magnetizing coil 112, and the second magnetizing coil 113 respectively; the ring-cutting switch 1113 can output a first current value and a second current value to the first magnetizing coil 112 and the second magnetizing coil 113 respectively, the first magnetizing coil 112 and the second magnetizing coil 113 generate a first magnetic attraction force from the first current value, the first magnetic attraction force drives the first blade 140 and the second blade 150 to slide a first preset stroke respectively; the first magnetizing coil 112 and the second magnetizing coil 113 generate a second magnetic attraction force from the second current value, the second magnetic attraction force drives the first blade 140 and the second blade 150 to slide a second preset stroke respectively.

[0052] Specifically, such as Figure 2 As shown, the battery compartment 1111 provides some protection for the battery 1112, reducing the possibility of damage to the battery 1112. One end of the ring-cutting switch 1113 is connected to the battery 1112 via a wire, and the other end is connected to the first magnetizing coil 112 and the second magnetizing coil 113 via wires. The ring-cutting switch 1113 is used to adjust the current value output by the battery 1112 to the first magnetizing coil 112 and the second magnetizing coil 113. By changing the output current value, the magnitude of the magnetic attraction force can be changed, thereby adjusting the movement stroke of the first blade 140 and the second blade 150.

[0053] In one specific embodiment of this application, the circumferential cutting switch 1113 can output a first current value and a second current value to the first magnetizing coil 112 and the second magnetizing coil 113 respectively, wherein the first current value is less than the second current value; the first magnetizing coil 112 and the second magnetizing coil 113 generate a first magnetic attraction force from the first current value and a second magnetic attraction force from the second current value, wherein the first magnetic attraction force is less than the second magnetic attraction force. Therefore, the first magnetic attraction force drives the first blade 140 and the second blade 150 to slide a first preset stroke respectively, and the second magnetic attraction force drives the first blade 140 and the second blade 150 to slide a second preset stroke respectively, wherein the first preset stroke is less than the second preset stroke.

[0054] The ring-cutting switch 1113 can also output a third current value to the first magnetizing coil 112 and the second magnetizing coil 113 respectively. The third current value is greater than the first current value and less than the second current value, so that the first magnetizing coil 112 and the second magnetizing coil 113 generate a third magnetic attraction force from the third current value. The third magnetic attraction force is greater than the first magnetic attraction force and less than the second magnetic attraction force. Therefore, the third magnetic attraction force can drive the first blade 140 and the second blade 150 to slide a third preset stroke respectively. The third preset stroke is less than the second preset stroke and greater than the first preset stroke.

[0055] For example, such asFigure 3 As shown, the first insert 120 includes a first upper baffle 121 and a first lower baffle 122 arranged in parallel opposite directions, and a first sidewall 123 connecting the first upper baffle 121 and the first lower baffle 122 respectively; a first sliding channel is formed between the first upper baffle 121 and the first lower baffle 122, and the first blade 140 is at least partially embedded in the first sliding channel and can slide along the first sliding channel; the second insert 130 includes a second upper baffle 131 and a second lower baffle 132 arranged in parallel opposite directions, and a second sidewall 133 connecting the second upper baffle 131 and the second lower baffle 132 respectively; a second sliding channel is formed between the second upper baffle 131 and the second lower baffle 132, and the second blade 150 is at least partially embedded in the second sliding channel and can slide along the second sliding channel.

[0056] Specifically, such as Figure 3 As shown, the inner side of the first insert 120 has a first sliding channel for the movement of the first blade 140. The first sliding channel has a hollow structure and is formed by a first upper baffle 121 and a first lower baffle 122 that are arranged opposite to each other. The first sliding channel ensures the stability of the sliding of the first blade 140. The first insert 120 also includes a first sidewall 123, which is used to fix the first upper baffle 121 and the first lower baffle 122.

[0057] Similarly, as Figure 3 As shown, the inner side of the second insert 130 has a second sliding channel for the movement of the second blade 150. The second sliding channel has a hollow structure and is formed by a second upper baffle 131 and a second lower baffle 132 that are arranged opposite to each other. The second sliding channel ensures the stability of the sliding of the second blade 150. The second insert 130 also includes a second sidewall 133, which is used to fix the second upper baffle 131 and the second lower baffle 132.

[0058] Optionally, such as Figure 1 , Figure 4 and Figure 5 As shown, a first threaded connection portion 1231 protrudes from the outer side of the first sidewall 123, and the first threaded connection portion 1231 is used to screw the first fastener 1232; the first fastener 1232 is rotated to drive the first insert 120 to move axially along the first fastener 1232 through the first threaded connection portion 1231; a second threaded connection portion 1331 protrudes from the outer side of the second sidewall 133, and the second threaded connection portion 1331 is screwed to the second fastener 1332; the second fastener 1332 is rotated to drive the second insert 130 to move axially along the second fastener 1332 through the second threaded connection portion 1331.

[0059] Specifically, please refer to Figure 1 and Figure 4The outer side of the first sidewall 123 is provided with a plurality of first threaded connection portions 1231, which are arranged at intervals. The first threaded connection portions 1231 are used to screw the first fastener 1232. When the first fastener 1232 rotates clockwise, the first threaded connection portions 1231 are driven to move the first insert 120 toward the first fastener 1232. At this time, the length of the first blade 140 exposed in the first insert 120 increases, thereby increasing the circumferential cutting depth. When the first fastener 1232 rotates counterclockwise, the first threaded connection portions 1231 are driven to move the first insert 120 away from the first fastener 1232. At this time, the length of the first blade 140 exposed in the first insert 120 decreases, thereby decreasing the circumferential cutting depth.

[0060] Similarly, please refer to Figure 1 and Figure 5 The outer side of the second sidewall 133 is provided with a plurality of second threaded connection portions 1331, which are arranged at intervals. The second threaded connection portions 1331 are used to screw the second fastener 1332. When the second fastener 1332 rotates clockwise, the second threaded connection portions 1331 are driven to move the second insert 130 toward the direction closer to the second fastener 1332. At this time, the length of the second blade 150 exposed in the second insert 130 increases, thereby increasing the circumferential cutting depth. When the second fastener 1332 rotates counterclockwise, the second threaded connection portions 1331 are driven to move the second insert 130 away from the second fastener 1332. At this time, the length of the second blade 150 exposed in the second insert 130 decreases, thereby decreasing the circumferential cutting depth.

[0061] Preferably, the first threaded connection portion 1231 and the second threaded connection portion 1331 are nuts; the first fastener 1232 and the second fastener 1332 are bolts.

[0062] This setup allows for precise control of the depth to which the blade cuts into the tobacco plant stem, ensuring that the girdling depth can be flexibly adjusted according to the growth needs of the tobacco leaves, further improving the flexibility and adaptability of girdling.
