Description

Technical Field

[0001] The present invention relates to the field of agricultural planting, and in particular to a branch binding buckle for fixing branches and tendrils of crops. Background Art

[0002] At present, in the field of agricultural planting, such as planting crops such as grapes and kiwis, it is necessary to manually control their growth trends or vine growth paths. The traditional method is to use ordinary plastic ropes to tie them manually, which is inefficient. With the development of technology, people have invented branch buckles to replace plastic ropes for tying crops.

[0003] For example, CN211745799U provides a new type of branch binding clamp, which includes a connecting rod 1 and fixing buckles 2 located at both ends of the connecting rod 1. Each fixing buckle 2 is further provided with three card slots, namely a first card slot 21, a second card slot 22, and a third card slot 23. The same type of branch binding clamp can be used on steel wires of different diameters and thicknesses.

[0004] CN210519640U discloses a novel branch-binding clip, comprising a connector and two clips, each mounted at either end of the connector and joined together by the connector. The clips are equipped with two different cylindrical slots and two anti-slip projections. By folding the connector in half and bending the clips, the clips secure the wire through the slots. The wire between the clip and the two clips forms a loop, which allows for positioning of branches of plants such as kiwifruit and grapes.

[0005] CN217064810U provides a grape branch binding clip, consisting of a binding ring and a U-shaped connector. The binding ring has a notch, one end of which is fixedly connected to one end of the U-shaped connector, and the other end extends inwardly of the binding ring. The plane of the binding ring and the plane of the U-shaped connector are perpendicular to each other. This clip can be used to bind and secure grape branches to the wire surface of a grape rack.

[0006] However, the above-mentioned branch tying buckles in the prior art are not firmly fixed to the wire and may move along the axial direction of the wire, resulting in poor binding and positioning effect on crops; in addition, the branch tying buckles in the prior art are easy to scratch vines or limbs, causing damage to crops; in addition, the prior art does not have a tool specifically for branch tying buckles, and the operator can only rely on his hands to clamp and fix the branch tying buckles on the wire; due to the small size and large number of branch tying buckles, during the binding operation, the operator cannot exert force and can only rely on his fingers to operate, which causes the operator's fingers to be painful and reduces production efficiency. Summary of the Invention

[0007] The present invention provides a branch binding buckle, which solves the problems in the prior art of poor binding and positioning effect on crops and easy scratching of crops.

[0008] The solution of the present invention to the above-mentioned technical problem is as follows: a branch binding buckle comprises a ring body and a connecting seat, the ring body is provided with a notch, and the crops to be tied are placed into the ring body through the notch; fixing buckles are provided at the left and right ends of the connecting seat, and a clamping block is provided in the middle of the connecting seat, and the clamping block is located between the fixing buckles; a clamping slot for accommodating an iron wire is provided at the bottom of the fixing buckle, the opening direction of the clamping slot is parallel to the central axis direction of the ring body, and the clamping block protrudes in the direction away from the ring body and is used to fix the iron wire in the clamping slot, and the iron wire is located between the clamping block and the clamping slot.

[0013] Preferably, a first inclined surface is provided on both the left and right sides of the fixing buckle, and a second inclined surface is provided on both the left and right sides of the clamping block.

[0014] Preferably, a flange is provided on the inner side of the ring body, and the surface of the flange in contact with the crops is a plane.

[0015] Preferably, the branch binding buckle is made of elastic plastic material.

[0016] Preferably, the ring body is in the shape of a spiral, and a gap is formed at the overlapping portion of the spiral.

[0017] The beneficial effects of the present invention are as follows: the branch binding buckle provided by the present invention has the following advantages:

[0018] 1. In order to prevent the ring from scratching the crops, a flange is provided on the inner side of the ring.

[0054] Example 1

[0055] like Figure 1-2 As shown, the present invention provides a branch binding buckle, comprising a ring body 91 and a connecting seat 92. The ring body 91 is provided with a notch 911. The ring body 91 is spiral-shaped, with the notch 911 formed at the overlapping portion of the spiral. The crops to be bound are placed into the ring body 91 through the notch 911. The spiral-shaped ring body 91 allows the crops to be easily placed into the ring body 91 while preventing them from slipping out of the ring body 91 through the notch 911. Furthermore, to prevent the ring body 91 from scratching the crops, a flange 912 is provided on the inner side of the ring body 91. The flange 912 contacts the crops, and the surface of the flange 912 in contact with the crops is flat. By increasing the contact area, the ring body 91 is prevented from scratching the branches or vines to be bound, thereby protecting the crops.

[0056] The flange 912 can be formed on the inner side of the ring body 91 by adding material or by using less material, for example, by cutting the inner side of the ring body 91 to form a flat surface in contact with crops as the flange 912 .

[0057] In order to improve the strength of the ring body 91 , the height of the flange 912 may be set to be greater than the height of the ring body 91 .

[0058] To strengthen the fixing effect between the branch binding buckle 9 and the wire, fixing buckles 92a are provided at the left and right ends of the connecting base 92, and a clamping block 92b is provided in the middle of the connecting base 92, and the clamping block 92b is located between the fixing buckles 92a. The fixing buckle 92a is a U-shaped structure with an upward opening. The bottom of the fixing buckle 92a is provided with a clamping slot 93 for accommodating the wire 10. The opening direction of the clamping slot 93 is parallel to the central axis OO of the ring body 91. The clamping block 92b protrudes away from the ring body 91 and is used to fix the wire in the clamping slot 93. When the wire is inserted into the clamping slot 93, the wire is located between the clamping block 92b and the clamping slot 93. The lower surface of the clamping block 92b acts on the wire to prevent it from slipping out of the opening of the clamping slot 93. Furthermore, the cross-force exerted by the clamping block 92b and the fixing buckle 92a on the wire increases the friction between the connecting base 92 and the wire, thereby improving the fixing force between the connecting base 92 and the wire.

[0059] like Figure 3 As shown, in order to adapt to different types of iron wires, a plurality of card slots 93 with different calibers are provided. The card slots 93 include a first card slot 93a and a second card slot 93b which are opened sequentially from top to bottom. The calibers of the first card slot 93a and the second card slot 93b are different. Specifically, the caliber of the first card slot 93a is usually set to be larger than the caliber of the second card slot 93b.

[0060] In order to facilitate the smooth entry of the iron wire into the slot 93, an arc surface 921 is provided on the side wall of the fixing buckle 92a, and a guiding slope 922 is provided on the side wall of the block 92b. The arc surface 921 and the guiding slope 922 are arranged relative to each other, so that the arc surface 921 and the guiding slope 922 form a guiding channel for guiding the iron wire 10 to enter the slot 93. The opening of the guide channel gradually decreases from top to bottom. Specifically, the opening of the guide channel is funnel-shaped.

[0061] The branch buckle 9 is made of a plastic material with elasticity, for example, PP, PE or nylon can be used; for plastic parts, injection molding is usually used, in order to facilitate demoulding, such as Figure 4 As shown, a slope 1 923 is provided on both sides of the fixing buckle 92a, and a slope 2 924 is provided on both sides of the blocking block 92b. Through this arrangement, only the upper and lower molds need to be designed, and no inclined block molds need to be added laterally to produce the branch binding buckle 9, which simplifies the mold structure and saves production costs.

[0062] When tying crops, first clamp the branch binding buckle 9 on the iron wire, press the iron wire through the guide channel formed by the arc surface 921 and the guide slope 922 with your fingers, and clamp it into the card slot 93. Then, put the branches or vines of the crops to be tied into the ring body 91 through the gap 911 to fix the branches or vines of the crops. Use the cross force of the clamping block 92b and the fixing buckle 92a to apply force to the iron wire to increase the friction between the connecting seat 92 and the iron wire, which makes it less likely for the connecting seat 92 to move along the axis of the iron wire, so that the branch binding buckle 9 can be stabilized at a certain position of the iron wire, playing a positioning role.

[0063] Example 2

[0064] In order to improve the clamping efficiency between the branch binding buckle 9 and the iron wire, the present invention also provides a branch binding pliers, which can be operated to clamp the iron wire into the branch binding buckle 9, instead of the operator's fingers applying force to clamp the branch binding ring into the iron wire, thereby improving production efficiency.

[0065] like Figure 5-6 As shown, the present invention provides a branch tying pliers comprising a first plier arm 2 and a second plier arm 5, which are rotatably connected and hinged to each other. A first jaw 1 is fixedly connected to the front end of the first plier arm 2, and a first handle 3 is sleeved on the rear end thereof. A second jaw 4 is fixedly connected to the front end of the second plier arm 5, and a second handle 6 is sleeved on the rear end thereof. The first jaw 1 is used to insert a branch tying ring 9 into the first jaw 1, and the second jaw 4 is used to press a wire into the branch tying ring 9.

[0066] like Figure 10 As shown, the branch binding pliers are used to press the wire into the branch binding ring 9. During the specific operation, the branch binding ring 9 is inserted into the first jaw 1, and the wire is located above the slot 93. The first jaw 1 and the second jaw 4 are closed by pressing the first handle 3 and the second handle 6 with the hands, and the wire is inserted into the slot 93.

[0067] In order to fix the branch binding ring 9 on the first jaw 1, an upwardly extending guide member 11 is provided at the front part of the first jaw 1, and a receiving groove 12 is provided at the bottom of the guide member 11. The front end of the first jaw 1 is connected to an elastic pressing device, and the branch binding ring 9 is placed between the guide member 11 and the elastic pressing device, wherein the receiving groove 12 is used to place the connecting seat 92 of the branch binding ring 9. The elastic force of the elastic pressing device makes the branch binding ring 9 close to the guide member 11, and then clamps the connecting seat 92 between the elastic pressing device and the guide member 11.

[0068] In order to smoothly press the wire into the slot 93, an opening 41 is provided at the front end of the second jaw 4, and the guide 11 can be inserted into the opening 41. A lower pressing groove 42 is provided at the bottom of the second jaw 4 for accommodating the wire; Figure 10As shown, when the hand holds and presses the first handle 3 and the second handle 6, the iron wire leans against the front surface of the guide 11. When the second jaw 4 moves downward, the iron wire first gets stuck in the downward pressing groove 42, and under the action of the downward pressing groove 42, the iron wire is pressed into the clamping groove 93. To facilitate fixing the iron wire, the downward pressing groove 42 can be an arc-shaped or "V"-shaped groove.

[0069] A torsion spring 7 is connected at the hinge joint of the first jaw arm 2 and the second jaw arm 5. One end of the torsion spring 7 is fixedly connected to the first jaw arm 2, and the other end is fixedly connected to the second jaw arm 5. Under the action of the torsion spring 7, the first jaw 1 and the second jaw 4 always remain open. When doing the binding work, after the iron wire is stuck into the branch tying ring 9, the first jaw 1 and the second jaw 4 automatically open to prepare for the next pressing. The operator only needs to continuously hold and press the first handle 3 and the second handle 6, and there is no need to apply force to separate the first jaw 1 and the second jaw 4, which has the effect of saving effort.

[0070] To prevent misoperation, a safety mechanism is also provided. The safety mechanism includes a lock 8. A locking rod 81 is provided on the lock 8. The lock 8 is rotatably connected to the second jaw arm 5. A lock groove 21 is provided on the first jaw arm 2. By rotating the lock 8, the locking rod 81 can be inserted into the lock groove 21. At this time, the first jaw arm 2 and the second jaw arm 5 cannot rotate in the closing direction; correspondingly, by rotating the lock 8 to make the locking rod rotate out of the lock groove 21, the safety can be released.

[0071] As Figure 7-9 As shown, to reduce the manufacturing cost, the first jaw 1 and the second jaw 4 are made of sheet metal parts. The first jaw 1 includes a first lower support plate 1a and a second lower support plate 1b. A connecting head 14 is connected between the first lower support plate 1a and the second lower support plate 1b; wherein, a first guiding piece 11a extending upward is provided at the front part of the first lower support plate 1a, and a second guiding piece 11b extending upward is provided at the front part of the second lower support plate 1b. The first guiding piece 11a and the second guiding piece 11b form the guide 11; a first groove 12a is provided at the bottom of the first guiding piece 11a, and a second groove 12b is provided at the bottom of the second guiding piece 11b. The first groove 12a and the second groove 12b form the accommodating groove 12; the elastic pressing device is installed on the connecting head 14.

[0072] The elastic pressing device can be an elastic structure such as a spring 13 or a spring piece. For example, the elastic pressing device is a spring 13. The spring 13 includes a spring head 132. Spring rods 132 extending downward are respectively provided on both sides of the spring head 132. A gap is formed between the two spring rods 132; the connecting head 14 is a "C"-shaped structure. First connecting holes 141 and second connecting holes 142 are provided on the left and right side plates of the connecting head 14, and a third connecting hole 143 is provided on its front side plate; As Figure 7As shown, the left and right side plates of the connector 14 are respectively connected to the guide piece 11a and the guide piece 2 11b; the front side plate of the connector 14 is connected to the spring 13, and the bolt passes through the gap formed between the third connecting hole 143 and the two spring rods 132. A spring washer and a nut are connected to the end of the bolt. The spring 13 is fixed to the front side plate of the connector 14 by tightening the nut. When the spring 13 is damaged, the nut can be loosened for replacement.

[0073] In addition, a support platform 144 is provided on the top of the connector 14. The surface of the support platform 144 is flush. The support platform 144 is used to contact the ring body 91 of the branch binding ring 9. The support platform 144 and the accommodating groove 12 ensure that the card slot 93 is aligned with the iron wire. During the pressing process of the branch binding clamp, the branch binding ring 9 is prevented from being crushed, so that the iron wire can be smoothly pressed into the card slot 93.

[0074] Furthermore, the second jaw 4 includes an upper pressing plate 1 4a and an upper pressing plate 2 4b, the bottom of the upper pressing plate 1 4a is provided with a lower pressing groove 1 42a, and the bottom of the upper pressing plate 2 4b is provided with a lower pressing groove 2 42b, and the lower pressing groove 1 42a and the lower pressing groove 2 42b constitute a lower pressing groove 42; the opening 41 is formed between the upper pressing plate 1 4a and the upper pressing plate 2 4b, and in order to ensure that the opening 41 is not deformed, a support rod 43 is also provided between the upper pressing plate 1 4a and the upper pressing plate 2 4b.

[0075] A lower pressing groove 42a is provided at the bottom of the upper pressing plate 4a; a lower pressing groove 42b is provided at the bottom of the upper pressing plate 4b, and the lower pressing groove 42a and the lower pressing groove 42b constitute the lower pressing groove 42, wherein the lower pressing groove 42a and the lower pressing groove 42b can be arc-shaped or "V"-shaped grooves.

[0076] Since the connecting head 14 is the main force-bearing component, it is prone to fatigue damage. In order to facilitate the replacement of the connecting head 14, the connecting head 14 and the first jaw 1 are connected in a detachable fixed manner. A left positioning protrusion 140a and a left connecting hole 130a are respectively provided at the front end of the guide piece 11a, and a right positioning protrusion 140b and a right connecting hole 130b are respectively provided at the front end of the guide piece 11b. The left positioning protrusion 140a and the right positioning protrusion 140b are respectively inserted into the second connecting holes 142 on both sides of the connecting head 14 to achieve preliminary positioning, and then the left side plate of the connecting head 14 is fixed by inserting bolts into the first connecting hole 141 and the left positioning protrusion 140a, and the right side plate of the connecting head 14 is fixed by inserting bolts into the first connecting hole 141 and the right positioning protrusion 140b.

[0077] Furthermore, the upper pressure plate 1 4a and the upper pressure plate 2 4b are fixedly connected to the front end of the second clamp arm 5, and the fixed connection method is bolt fixation, welding fixation or adhesive fixation; the lower support plate 1a and the lower support plate 2 1b are fixedly connected to the front end of the first clamp arm 2, and the fixed connection method is bolt fixation, welding fixation or adhesive fixation.

[0078] When bolts are used for fixing, a left mounting hole 201 and a right mounting hole 202 are respectively opened at the front of the first clamp arm 2, and corresponding mounting holes are opened at the upper pressure plate 1 4a and the upper pressure plate 2 4b. The bolts pass through the left mounting hole 201 and the right mounting hole 202 to connect with the upper pressure plate 1 4a and the upper pressure plate 2 4b; a left positioning circular hole 501 and a right positioning circular hole 502 are opened at the front of the second clamp arm 5, and the bolts pass through the left positioning circular hole 501 and the right positioning circular hole 502 to connect with the lower support plate 1 1a and the lower support plate 2 1b.

[0079] The working principle of the branch tying calipers is as follows:

[0080] like Figure 10-13 As shown, in the initial state, the first jaw 1 and the second jaw 2 of the branch tying caliper are kept open under the action of the torsion spring 7; first, the branch tying ring 9 is clamped and fixed on the first jaw 1, specifically by placing the connecting seat 92 of the branch tying ring 9 into the receiving groove 12, and the elastic force of the spring 13 clamps the connecting seat 92 between the spring 13 and the guide 11, thereby fixing the branch tying ring 9; secondly, the branch tying ring 9 to be clamped is moved to the bottom of the iron wire, at this time the iron wire is located between the first jaw 1 and the second jaw 2, and the iron wire is fixed. It contacts the front side of the guide 11 and is located above the slot 93; then, the first handle 3 and the second handle 6 are squeezed to rotate the first jaw 1 and the second jaw 2 in the closing direction. At this time, the downward pressing groove 42 of the second jaw 4 drives the wire to move downward, and finally presses the wire into the slot 93; finally, the branches or vines of the crops to be tied are placed into the ring body 91 through the notch 911 to complete one binding; after the binding is completed, let go, the first jaw 1 and the second jaw 2 are opened and reset, and the operation is repeated in this way.
