[0001] This utility model relates to the field of agricultural production binding tools, and in particular to a nail-pushing device and a branch-binding machine. Background Technology

[0002] When planting crops such as tomatoes, grapes, and kiwis, we usually need to fix the vines or branches of the plants to bamboo poles or wires to guide their growth or assist in fruit setting, thereby improving crop yield and quality. In order to improve the efficiency of tying branches, compared with the traditional method of using ropes to tie branches, operators now usually use branch tying machines (also known as binding machines) to tie and fix the plants.

[0003] Currently, tying machines are usually equipped with a nail-pushing device for providing tying nails. For example, CN222424842U discloses a nail-pushing block and a tying machine. The nail-pushing device includes a nail box with a groove for placing tying nails inside. One end of the groove has a nail outlet at the bottom. The nail-pushing assembly is slidably disposed in the groove for pushing the tying nails.

[0004] However, the existing push-nail devices have the following shortcomings: the head of the push-nail block is grooved, and the contact area with the binding nail is too small, which can easily cause wear and eventually cause the nail to jam, affecting the user's binding efficiency.

[0036] The principles and features of this utility model are described below with reference to Figures 1-7. The examples given are for illustrative purposes only and are not intended to limit the scope of this utility model. The utility model is described more specifically in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of this utility model will become clearer from the following description and claims. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of this utility model.

[0037] It should be noted that when a component is described as "fixed to" another component, it can be directly on the other component or may have a component in between. When a component is considered "connected to" another component, it can be directly connected to the other component or may have a component in between. When a component is considered "set on" another component, it can be directly set on the other component or may have a component in between. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0038] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0039] Please refer to Figures 1 and 2. This utility model provides a nail-pushing device for use on a branch tying machine. It is installed on the branch tying machine and can provide the branch tying machine with binding nails when the branch tying machine is performing the nailing action, thereby completing the nailing action of the binding nails.

[0040] Furthermore, the nail-pushing device includes a nail box 100, a nail-pushing assembly 200, and a limiting plate 300. The nail-pushing assembly 200 is slidably disposed within the nail box 100, and the limiting plate 300 limits the sliding distance of the nail-pushing assembly 200 within the nail box 100 to avoid the situation where the nail-pushing assembly 200 is fatigued due to excessive pushing and pulling force when placing the strap nails, thus preventing unstable nail supply.

[0041] Please refer to Figures 2-3. Specifically, the nail box 100 is elongated and has a groove 110. The groove 110 preferably extends through the interior of the nail box 100, and a nail outlet 120 for feeding nails is provided at the bottom of one end of the groove 110. The nail pusher assembly 200 is slidably disposed in the groove 110. It can be understood that the nail pusher assembly 200 has a certain kinetic potential energy and can push the strap nails to the nail outlet 120.

[0042] On the nail box 100, a limiting plate 300 is provided on the outer edge of the slide groove 110 to limit the sliding distance of the push nail assembly 200 in the slide groove 110. The limiting plate 300 is provided facing the inner side of the slide groove 110. One or more limiting plates 300 can be provided. Furthermore, the limiting plates 300 are provided opposite to each other on both sides of the outer edge of the slide groove 110.

[0043] When the pusher assembly 200 slides within the slide groove 110 after being subjected to force, an area for placing the strap nail appears on one side of the slide groove 110 near the nail outlet 120. After the strap nail is placed, the pusher assembly 200 can push the strap nail towards the nail outlet 120. When the pusher assembly 200 slides, the limiting plate 300 can prevent the pusher assembly 200 from sliding too much, thus avoiding fatigue caused by excessive pushing and pulling force on the pusher assembly 200 itself, resulting in insufficient pushing force on the strap nail and unstable nail supply of the pusher device.

[0044] Furthermore, the limiting plate 300 is positioned in the middle of the nail box 100, thereby limiting the sliding distance of the pusher assembly 200 to only between the nail outlet 120 and the limiting plate 300. At the same time, the area between the nail outlet 120 and the limiting plate 300 within the slide groove 110 can be used to place strap nails.

[0045] Please refer to Figures 4 and 5. The nail-pushing device also includes a dust cover 400, which is fixedly connected to the nail-pushing assembly 200 and is slidably mounted on the slide groove 110. As the nail-pushing assembly 200 slides synchronously, the dust cover 400 completely covers the nail-pushing assembly 200 within the slide groove 110, effectively preventing the nail-pushing assembly 200 from being corroded by dust and moisture, thereby ensuring the movement capability of the nail-pushing assembly 200 and also improving the service life of the tying machine.

[0046] Please refer to Figures 3 and 4. A first locking plate 130 and a second locking plate 140 are provided at the end of the nail box 100 away from the nail outlet 120. A first locking block 131 is provided on the first locking plate 130, and a second locking plate 141 is provided on the second locking plate 140. Two slots 410 are provided at the end of the dust cover 400 away from the nail outlet 120. The first locking block 131 and the second locking block 141 can be respectively locked into the two slots 410. The slots 410 can be square holes, round holes, U-shaped holes, or other shaped notches. A pressing structure 420 is provided at the rear end of the dust cover 400.

[0047] Specifically, when the pusher assembly 200 is not subjected to external force and the tying machine is not using tie nails, the dust cover 400 can seal the pusher assembly 200 within the slide groove 110, and the dust cover 400 completely seals the slide groove 110. At this time, the first locking block 131 and the second locking block 141 are engaged in the slot 410, so that the dust cover 400 can be locked and fixed on the nail box 100. This avoids the pusher assembly 200, which is fixedly connected to the dust cover 400, from being subjected to secondary force, and also ensures that the pusher assembly 200 is not subject to dust intrusion. (It should be explained that if there is no cooperation between the first / second locking block and the slot 410, the dust cover 400 will slide on the nail box 100 under its own weight, thereby driving the movement of the pusher assembly 200 and causing the pusher assembly 200 to be subjected to secondary force.)

[0048] When it is necessary to place a strapping nail into the nail box 100, the pressing structure 420 needs to be operated to disengage the first locking block 131 and the second locking block 141 from the locking groove 410, and further pull the pusher assembly 200 to slide in the slide groove 110, so that a space for placing the strapping nail is formed in the slide groove 110.

[0049] The pressing structure 420 can be an elastic plate with elastic characteristics, or it can be a connecting plate with an unlocking function.

[0050] To improve the operating comfort of the pressing structure 420, an anti-slip structure 421 is provided on the pressing structure 420. The anti-slip structure 421 can be an anti-slip thread or an anti-slip protrusion.

[0051] Please refer to Figure 4-5. A first limiting edge 430 and a second limiting edge 440 are respectively provided on both sides of one end of the dust cover 400. The first limiting edge 430 and the second limiting edge 440 are arranged opposite to each other and are sleeved on both sides of the nail box 100.

[0052] Furthermore, the first limiting edge 430 and the second limiting edge 440 are disposed at one end of the dust cover 400 near the nail outlet 120, and can slide on both sides of the nail box 100. Both the first limiting edge 430 and the second limiting edge 440 are provided with limiting protrusions 450, which can prevent the dust cover 400 from detaching from the slide groove 110, effectively ensuring that the movement position of the dust cover 400 when sliding on the nail box 100 is not easily changed.

[0053] In the technical solution of this utility model, as shown in Figures 4-7, the push-pin assembly 200 preferably includes a push-pin head 210, a support rod 220, a spring 230, and an abutment 240. The abutment 240 is fixedly connected to the dust cover plate 400, and a through hole is provided on the abutment 240. The support rod 220 is fixed to the through hole on the abutment 240. The fixing method can be snap-fit, adhesive, welding, threaded connection, or any other form. For example, when using the snap-fit ​​method (as shown in Figure 6), a fixing groove 221 is provided at the rear end of the support rod 220. After the support rod 220 passes through the through hole of the abutment 240, the fixing groove 221 is snap-fitted and fixed to the through hole of the abutment 240. When using the threaded connection method, a threaded through hole is provided on the abutment 240, and a thread is provided at the corresponding position at the end of the support rod 220. The support rod 220 is tightened and fixed to the through hole on the abutment 240.

[0054] Furthermore, the pusher head 210 is slidably sleeved on the front end of the support rod 220, and the spring 230 is sleeved on the outer periphery of the support rod 220 and abuts against the pusher head 210; the spring 230 is sleeved on the support rod 220, and the two ends of the spring 230 are in contact with the pusher head 210 and the abutment head 240 respectively.

[0055] After the dust cover 400 is pulled, the pusher head 210 can be pulled to slide in the slide groove 110. The pusher head 210 further compresses the spring 230, so that the spring 230 has driving potential energy on the pusher head 210, which in turn can drive the strap nail in the slide groove 110 to move towards the nail outlet 120.

[0056] To prevent the pusher head 210 from dislodging from the front end of the support rod 220, the pusher head 210 has a through hole inside, and a stepped hole 211 is provided at the front end of the through hole. The diameter of the stepped hole 211 is larger than the diameter of the through hole. A limiting post 222 is provided at the front end of the support rod 220. The diameter of the limiting post 222 is larger than the diameter of the main body of the support rod 220. The main body of the support rod 220 and the through hole are clearance-fitted. When the pusher head 210 moves to the front end of the support rod 220, the limiting post 222 is slidably connected in the stepped hole 211. The limiting post 222 can prevent the pusher head 210 from dislodging from the front end of the support rod 220.

[0057] The front end of the pusher head has no groove, and the front end face of the pusher head is convex, concave or flat. The stepped hole penetrates the front end face. Compared with the traditional pusher head, the pusher head 210 provided by this utility model has no groove at the front end, has higher strength and is not easily deformed, so there will be no problem of pusher head jamming.

[0058] When the dust cover 400 is pulled, the pusher head 210 can slide in the groove 110. After the pusher head 210 pushes the strap nail, the dust cover 400 can be pushed to cover the area where the strap nail is located. This not only provides a stable driving force for the strap nail, but also protects the strap nail from dust.

[0059] When the pusher head 210 pushes the binding nail toward the nail outlet 120, a nail guard plate 150 is provided on the nail box 100 at the relative position of the nail outlet 120 to protect the binding nail and prevent the binding nail from falling out of the slide groove 110. This can improve the stability of the binding nail and effectively improve the nailing accuracy and nailing efficiency of the branch binding machine.

[0060] In this technical solution, by installing the nail-pushing device onto the branch-tying machine, the nailing accuracy and effect of the branch-tying machine can be effectively improved.

[0061] Working principle of the branch tying machine: The branch tying machine includes standby mode, strap gripping mode, branch tying mode, and strap binding and cutting mode. A clamping device 1 is installed at the front end of the bow-shaped frame 2, allowing the binding strap to be pulled out from the front end of the frame 4. A nail outlet is provided at the front end of the nail pusher 5, and the clamping device 1 cooperates with the nail outlet. In the standby mode, the bow-shaped frame 2 is in the open position relative to the frame 1. In the strap gripping mode, force is applied by squeezing the handle 3, causing the bow-shaped frame 2 to rotate downwards clockwise relative to the frame 4. As the bow-shaped frame 2 rotates, the clamping device 1 contacts the front end of the frame 4, thus clamping the binding strap. In the branch-tying state, release the pressure on the handle 3 and the bow-shaped frame 2 will rotate upwards counterclockwise. As the bow-shaped frame 2 rotates, the binding strap is stretched. After inserting the branch-tying machine into the desired branch position, let the binding strap wrap around the branch to complete the tying. In the binding and cutting state, after adjusting the binding strap to the appropriate position on the branch, press the handle 3. The bow-shaped frame 2 will move downwards again until the clamping device 1 contacts the front end of the frame 4. Press the handle 3 further, and the binding strap nail in the nail pusher 5 will attach the binding strap from the nail outlet. Release the handle 3 again, and the bow-shaped frame 2 will return to the open position, thus completing one branch-tying operation. Repeating the above actions can achieve branch-tying operations for various branches.
