Description

Technical Field

[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 binding 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 binding nails inside. One end of the groove has a nail outlet at the bottom. The nail-pushing assembly is slidably disposed in the groove and is used to push the binding nails.

[0004] However, existing nail-pushing devices have the following shortcomings: traditional nail-pushing components are prone to fatigue during the nail-pushing process, which leads to unstable nail feeding action in the nail box, easily causing uncoordinated nailing action or serious nail jamming. In addition, the head of the nail-pushing block is grooved, resulting in too small a contact area with the binding nail, which easily causes wear and ultimately causes nail jamming, affecting the user's binding efficiency. Utility Model Content

[0005] This utility model provides a nail-pushing device and a branch-tying machine to solve the problems of fatigue and nail jamming in the existing nail-pushing device.

[0006] The present invention provides the following solution to the above-mentioned technical problems: a nail-pushing device, which is used to be assembled onto the main body of a branch-tying machine and to provide the branch-tying machine with binding nails. The nail-pushing device includes: a nail box, in which a groove for placing binding nails is provided, and a nail outlet is provided at the bottom of one end of the groove; a nail-pushing assembly, which is slidably disposed in the groove and used to push the binding nails; a dust cover plate connected to the nail-pushing assembly; and a limiting structure disposed on the groove, which includes a protruding ridge on the outer wall of the groove and a stop block provided on the rear side of the protruding ridge. The limiting structure is used to limit the sliding distance of the dust cover plate on the groove.

[0007] Preferably, the dust cover is used to seal the push pin assembly within the groove; the dust cover has a first limiting edge and a second limiting edge on both sides, and a sliding pin, a limiting protrusion or a sliding fold is provided on the first limiting edge and the second limiting edge, and the sliding pin is slidably connected to the lower surface of the protrusion.

[0008] Preferably, the protruding edge and the stop are provided with avoidance holes, and the sliding pin, the limiting protrusion or the sliding fold can be engaged with the lower surface of the protruding edge through the avoidance holes.

[0009] Preferably, a first groove is formed on the inner surface of the side wall of the slide groove, the first groove being used to reduce the sliding friction between the pusher head and the slide groove.

[0010] The pusher assembly includes a pusher head, a support rod, and a spring. The pusher head is slidably sleeved on the front end of the support rod, and the spring is sleeved on the outer periphery of the support rod and abuts against the pusher head. A stepped hole is provided in the pusher head, and a limit post is provided at the front end of the support rod. The limit post is slidably connected in the stepped hole and is used to prevent the pusher head from dislodging from the front end of the support rod. The front end face of the pusher head is convex, concave, or flat, and the stepped hole penetrates the front end face.

[0011] The push pin assembly also includes an abutment plate, which is fixedly connected to the dust cover plate, and the abutment plate has a through hole, through which the support rod is connected.

[0012] The support rod can pass through the through hole, and a fixing groove is provided at the rear end of the support rod. The fixing groove is engaged and fixed with the through hole of the abutment plate.

[0013] The support rod is threadedly connected to the through hole on the abutment plate.

[0014] The dust cover is provided with a pressing structure at its rear end. The pressing structure can drive the slot to disengage from the first and second blocks. The pressing structure is provided with an anti-slip structure.

[0015] A branch-tying machine is also provided, preferably including the aforementioned nail-pushing device.

[0016] The beneficial effects of this utility model are as follows: The pusher device provided by this utility model has the following advantages:

[0017] 1. By setting protruding ridges on both sides of the chute and providing a stop block on the rear side of the protruding ridge, and by providing sliding pins, limiting protrusions, or sliding flanges on both the first and second limiting edges of the dust cover, the sliding pins are slidably connected to the lower surface of the protruding ridges; the sliding pins, limiting protrusions, or sliding flanges are engaged with the protruding ridges to restrict the up-and-down swaying of the dust cover; at the same time, the stop block limits the sliding distance of the dust cover and the pusher assembly, reducing fatigue damage to the pusher assembly, thereby effectively improving the stability of the nail supply.

[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] Example 1

[0040] Please see Figure 1 and Figure 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.

[0041] The pusher device includes a nail box 100, a pusher assembly 200, and a limiting plate 300. The pusher assembly 200 is slidably disposed in the slide groove 110 of the nail box 100 for pushing the strap nails. The dust cover 400 is connected to the pusher assembly 200.

[0042] Please continue reading. Figure 2-3 Specifically, the nail box 100 is elongated and has a groove 110 that extends through the interior of the nail box 100. 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.

[0043] When the pusher assembly 200 slides in 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 toward the nail outlet 120.

[0044] Please continue reading. Figure 4 and Figure 5The dust cover 400 is fixedly connected to the push nail assembly 200, and the sliding cover is provided on the slide groove 110. Simultaneously, as the push nail assembly 200 slides synchronously, the dust cover 400 is used to completely cover the push nail assembly 200 in the slide groove 110, effectively preventing the push nail assembly 200 from being corroded by dust and moisture, thereby ensuring the movement capability of the push nail assembly 200 and also improving the service life of the tying machine.

[0045] Please see Figure 4-5 On both sides of one end of the dust cover 400, a first limiting edge 430 and a second limiting edge 440 are respectively provided. 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. The first limiting edge 430 and the second limiting edge 440 are located at the end of the dust cover 400 near the nail outlet 120 and can slide on both sides of the nail box 100. Each of the first limiting edge 430 and the second limiting edge 440 is provided with a sliding pin 450 (limiting protrusion 450). The sliding pin 450 (limiting protrusion 450) 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.

[0046] Furthermore, a limiting structure is provided on the slide groove 110, the limiting structure including a protruding rib 160 formed on the outer wall of the slide groove 110, and the sliding pin 450 is slidably connected to the lower surface of the protruding rib 160.

[0047] A stop 180 is provided on the rear side of the protruding ridge 160. The limiting structure is used to limit the sliding distance of the dust cover 400 on the slide groove 110. Furthermore, the stop 180 is located in the middle of the nail box 100, thereby limiting the sliding distance of the dust cover 400 to be between the nail outlet 120 and the stop 180. At the same time, the area between the nail outlet 120 and the limiting plate 300 in the slide groove 110 can be used to place tie-on nails. This is to avoid the tie-on nail pusher assembly 200 shaking up and down due to excessive pushing and pulling force when placing tie-on nails, and to avoid excessive back-and-forth movement of the dust cover 400, which could cause fatigue damage to the tie-on nail pusher assembly and lead to unstable nail supply.

[0048] Please see Figure 4 and Figure 5A 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.

[0049] 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.)

[0050] 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. This further pulls the pusher assembly 200 to slide in the slide groove 110, thus creating a space within the slide groove 110 for placing the strapping nail. The pressing structure 420 can be an elastic plate with elastic characteristics, or it can be a connecting plate with an unlocking function.

[0051] 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.

[0052] In the technical solution of this utility model, such as Figure 6-8 As shown, the push-pin assembly 200 preferably includes a push-pin head 210, a support rod 220, a spring 230, and an abutment plate 240. The abutment plate 240 is fixedly connected to the dust cover 400, and a through hole is provided on the abutment plate 240. The support rod 220 is fixed to the through hole on the abutment plate 240. The fixing method can be snap-fit, adhesive, welding, threaded connection, or any other form. For example, when using a snap-fit ​​connection (such as...), Figure 6As shown, 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 plate 240, the fixing groove 221 is engaged and fixed with the through hole of the abutment plate 240. When a threaded connection is used, a threaded through hole is provided on the abutment plate 240, and a thread is provided at the corresponding position on the end of the support rod 220. The support rod 220 is tightened and fixed with the through hole on the abutment plate 240.

[0053] 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 plate 240 respectively.

[0054] 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.

[0055] To prevent the pusher head 210 from dislodging from the front end of the support rod 220, a through hole is provided inside the pusher head 210, 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.

[0056] Furthermore, the front end of the pusher head 210 has no groove, so the front end face of the pusher head 210 is a convex surface, a concave surface, or a plane. The stepped hole penetrates the front end face. Compared with traditional pusher heads, the pusher head 210 provided by this utility model has no groove at the front end, has higher strength, is not easily deformed, and therefore will not have the problem of pusher head jamming.

[0057] 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.

[0058] 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 improves the stability of the binding nail and also effectively improves the nailing accuracy and nailing efficiency of the branch binding machine.

[0059] 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.

[0060] Working principle of the branch tying machine: The branch tying machine includes a standby state, a strap gripping state, a branch tying state, and a strap binding and cutting state. 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 state, the bow-shaped frame 2 is in the open position relative to the frame 1. In the strap gripping state, 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 rotate the bow-shaped frame 2 counterclockwise upwards. 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 moves 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 attaches to the binding strap from the nail outlet. Release the handle 3 again, and the bow-shaped frame 2 returns to the open position, thus completing one branch-tying operation. Repeating the above actions can achieve branch-tying operations for various branches.

[0061] Example 2

[0062] Please see Figure 9 Unlike Embodiment 1, this embodiment provides limiting protrusions 450 on both the first limiting edge 430 and the second limiting edge 440. The limiting protrusions 450 are formed by a stamping process. The limiting protrusions 450 can prevent the dust cover 400 from detaching from the slide groove 110. When the dust cover 400 is engaged with the limiting structure, it is slidably connected to the lower surface of the protrusion 160 through the limiting protrusions 450.

[0063] Example 3

[0064] Please see Figure 10Unlike embodiments 1-2, this embodiment has a sliding folded edge 452 on both the first limiting edge 430 and the second limiting edge 440. The sliding folded edge 452 is formed by a folding process. The sliding folded edge 452 can prevent the dust cover 400 from detaching from the slide groove 110. When the dust cover 400 is engaged with the limiting structure, it is slidably connected to the lower surface of the protrusion 160 through the sliding folded edge 452.
