[0001] This application belongs to the field of stubble removal knife processing technology, and more specifically, it relates to a stubble removal knife feeding machine structure and welding equipment. Background Technology

[0002] A stubble cutter is a specialized tool used in agricultural production to remove stubble residue after crop harvesting. It is typically installed on agricultural machinery such as stubble cutters and straw return machines, and is a key component for straw treatment and soil tillage.

[0003] During the production of stubble-clearing knives, it is often necessary to fix the knives in place for processing, such as welding a wear-resistant layer to the side of the knives. Currently, the common practice is for the operator to manually place the knives into a fixture, clamp it, and then proceed with processing. This method requires manually placing each knives one by one, posing a safety hazard of injury from the fixture, and is also labor-intensive, inefficient, and makes it difficult to guarantee feeding accuracy. Utility Model Content

[0018] In some embodiments, the hopper is provided with a telescopic pressure head, which presses the tails of each of the stubble-cutting knives against the positioning sidewall.

[0019] In some embodiments, the stubble-cutting knife feeder structure further includes a positioning sensor located at the end of the guide plate away from the discharge port and adapted to detect the blade head of the stubble-cutting knife.

[0020] The beneficial effects of the stubble-cutting knife feeding machine structure provided in this application embodiment are as follows: Compared with the prior art, the stubble-cutting knife feeding machine structure of this application embodiment allows the operator to place at least one stubble-cutting knife into the hopper at a time, so that the stubble-cutting knife is stacked on the positioning side wall; then, the ejection mechanism pushes one stubble-cutting knife against the positioning side wall out of the hopper through the discharge port through the pusher, and moves the stubble-cutting knife along the guide plate; the guide plate is at least partially magnetic, which can attract the stubble-cutting knife, so that the stubble-cutting knife is attached to the guide plate for positioning, so that the stubble-cutting knife can be processed directly on the guide plate, or it can be clamped by an additional clamping device before processing;

[0021] The stubble-cutting knife feeding machine structure of this solution eliminates the need for operators to manually place the stubble-cutting knife into the processing position, reducing safety hazards.

Therefore, they should not be construed as limitations on this application.

[0034] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" or "several" means two or more, unless otherwise explicitly specified.

[0035] Please refer to the following: Figures 1 to 4 The structure of the stubble-cutting knife feeder provided in the embodiments of this application will now be described. A stubble-cutting knife feeder structure includes: a hopper 1, an ejection mechanism 2, and a guide plate 3.

[0036] The hopper 1 has a discharge port 11 and a positioning sidewall 12 for guiding the discharge port 11; the hopper 1 is suitable for storing at least one stubble-cutting knife 5, and at least one stubble-cutting knife 5 is stacked on the positioning sidewall 12.

[0037] The ejection mechanism 2 has a pusher 21, which is adapted to move in a predetermined direction to eject the stubble-removing knife 5, which is attached to the positioning sidewall 12, from the discharge port 11 along the positioning sidewall 12.

[0038] The guide plate 3 is located at the discharge port 11 and is continuous with the positioning side wall 12 so that the stubble-cutting knife 5 can move along the positioning side wall 12 to the guide plate 3; the guide plate 3 is at least partially magnetic so as to attract the positioning stubble-cutting knife 5.

[0039] Compared with the prior art, the stubble-removing knife feeding machine structure of this application embodiment allows the operator to place at least one stubble-removing knife 5 into the hopper 1 at a time, so that the stubble-removing knife 5 is stacked on the positioning side wall 12; then, the ejection mechanism 2 pushes one of the stubble-removing knives 5 against the positioning side wall 12 out of the hopper 1 through the pusher 21, and moves the stubble-removing knife 5 to the guide plate 3; the guide plate 3 is at least partially magnetic, which can attract the stubble-removing knife 5, so that the stubble-removing knife 5 is attached to the guide plate 3 for positioning, so that the stubble-removing knife 5 can be processed directly on the guide plate 3, or it can be clamped by an additional clamping device before processing.

[0040] The stubble-cutting knife feeding machine structure of this solution avoids the operator manually placing the stubble-cutting knife 5 into the processing position, reducing safety hazards; moreover, automated feeding reduces the operator's labor intensity and improves efficiency, while also improving repeatability accuracy compared to manual feeding.

[0041] Traditional manual feeding methods require a significant investment of manpower, and with labor costs rising year by year, enterprise personnel expenses are constantly increasing. The stubble-cutting knife feeding machine structure of this embodiment can replace manual feeding, significantly reducing labor costs. Previously, each production line required one worker for manual feeding, with an annual salary of 80,000 yuan per person. With the stubble-cutting knife feeding machine structure of this embodiment, one worker can feed at least six production lines simultaneously, reducing the number of workers by at least five and saving up to 400,000 yuan in labor costs annually. Furthermore, the equipment maintenance cost is far lower than the labor cost, saving enterprises substantial funds in the long run and effectively reducing production costs. Moreover, the stubble-cutting knife feeding machine structure of this embodiment effectively prevents workplace accidents, protecting workers' lives and health, reflecting the enterprise's humanistic care for its employees, and contributing to the construction of harmonious and stable labor relations.

[0042] Furthermore, the application of this automated feeding equipment provides an automation solution for the stubble-cutting knife production industry, helping to drive the entire industry towards automation and intelligence. The improvement of industry automation levels not only increases production efficiency and product quality but also drives the development of related industries, such as automated equipment manufacturing and software development. At the same time, industry automation upgrades also help improve my country's international competitiveness in the agricultural machinery manufacturing sector and promote the sustainable development of related industries.

[0043] A typical stubble-crushing blade 5 usually consists of a blade tail 52 for connecting to a rotating shaft and a blade head 51 for crushing straw. Typically, the blade head 51 and the blade tail 52 are bent together at an obtuse angle, with the end of the blade tail 52 furthest from the blade head 51 being the blade tail 52.

[0044] In this embodiment, the hopper 1 is mainly used to store one or more stubble-cutting knives 5, and to stack the stubble-cutting knives 5 on the positioning sidewall 12. The positioning sidewall 12 positions the attached stubble-cutting knives 5 and provides some guidance when the stubble-cutting knives 5 are pushed out. Specifically, the hopper 1 is formed by a bottom plate and sidewalls surrounding the bottom plate. A notch is provided on the sidewall to form a discharge port 11, and the sidewall adjacent to the discharge port 11 forms the positioning sidewall 12. The positioning sidewall 12 is typically a flat sidewall, designed to fit against the side of the stubble-cutting knife 5's head 51 or tail 52. In use, when the pushing mechanism 2 pushes out the stubble-cutting knife 5 attached to the positioning sidewall 12 through the movement of the pushing member 21, the pushing member 21 is withdrawn, and the remaining stubble-cutting knives 5 continue to be stacked on the positioning sidewall 12.

[0045] The ejection mechanism 2 can drive the pusher 21 through a cylinder, gear rack, or other means, so that the pusher 21 can push the stubble-removing knife 5, which is attached to the positioning sidewall 12, out of the discharge port 11. The predetermined direction of movement of the pusher 21 can be parallel to the positioning sidewall 12 and towards the horizontal direction of the discharge port 11.

[0046] The guide plate 3 is used to receive the stubble-cutting knife 5 pushed out from the discharge port 11 of the hopper 1. The guide plate 3 is at least partially magnetic, so that after the stubble-cutting knife 5 moves from the positioning side wall 12 along the guide plate 3, the stubble-cutting knife 5 can be attracted to the guide plate 3 to ensure the positioning of the stubble-cutting knife 5.

[0047] In specific implementation, the attraction of the guide plate 3 to the stubble-cutting knife 5 is sufficient to allow the stubble-cutting knife 5 to adhere to the guide plate 3 for positioning. The attraction of the guide plate 3 can be very strong, so that even without support below, the stubble-cutting knife 5 can be firmly adhered to the guide plate 3 for positioning, and the stubble-cutting knife 5 can also be pushed by the pusher 21. The attraction of the guide plate 3 to the stubble-cutting knife 5 can be relatively weak, by setting a support plate below the stubble-cutting knife 5 to provide some support. In this case, the attraction of the guide plate 3 to the stubble-cutting knife 5 still needs to prevent the stubble-cutting knife 5 from shifting due to inertia, vibration, or external processing forces (such as external forces generated by welding), thus achieving positioning of the stubble-cutting knife 5. The positioning sidewall 12 and the guide plate 3 can be located on the same plane, so that when the stubble-cutting knife 5 is pushed out, it can smoothly move from the positioning sidewall 12 to the guide plate 3. The positioning sidewall 12 and the guide plate 3 can be integrally set or separately set.

[0048] Please see Figures 1 to 4 As a specific embodiment of the stubble-removing knife feeding machine structure provided in this application, the guide plate 3 is provided with at least one magnetic block 31; the position of at least one magnetic block 31 is configured such that the stubble-removing knife 5 is attracted by the magnetic block 31 before it is separated from the positioning side wall 12.

[0049] In this embodiment, the guide plate 3 is locally magnetic by providing magnetic blocks 31. The magnetic blocks 31 are positioned relatively close to the positioning sidewall 12 to ensure that the stubble-removing knife 5, which is attached to the positioning sidewall 12, is attracted by the magnetic blocks 31 before being pushed away from the positioning sidewall 12 by the pushing member 21. See [link to documentation]. Figure 3 In practice, the magnetic block 31 can be a permanent magnet or an electromagnet.

[0050] Please see Figures 1 to 4 As a specific embodiment of the stubble-removing knife feeding machine structure provided in this application, the magnetic attraction of the guide plate 3 to the stubble-removing knife 5 satisfies the following: the resultant force of the magnetic attraction and friction between the stubble-removing knife 5 and the guide plate 3 can counteract the gravity of the stubble-removing knife 5, so that the stubble-removing knife 5 is positioned on the guide plate 3.

[0051] In this embodiment, the magnetic attraction of the guide plate 3 is set to be relatively strong, and the stubble-cutting knife 5 is attracted to the guide plate 3, creating friction between the stubble-cutting knife 5 and the guide plate 3. The combined force of the magnetic attraction and friction can counteract the gravity of the stubble-cutting knife 5, preventing it from sliding downwards along the guide plate 3 due to its own weight. Therefore, it is unnecessary to place a support plate under the stubble-cutting knife 5 for support, avoiding the support plate interfering with subsequent equipment's gripping or processing of the stubble-cutting knife 5 positioned on the guide plate 3. (Reference) Figure 4 The stubble-cutting knife 5 is attached to the guide plate 3 and suspended below without any support.

[0052] Please see Figure 1 ,3 In embodiment 4, as a specific implementation of the stubble-removing knife feeding machine structure provided in this application, the tails 52 of each stubble-removing knife 5 are stacked on the positioning side wall 12, the heads 51 face the discharge port 11, and the pusher 21 is opposite to the tail end of the stubble-removing knife 5 that is attached to the positioning side wall 12.

[0053] The stubble-cutting blade 5 includes a tail 52 and a head 51, and the tail 52 and head 51 of the stubble-cutting blade 5 are usually set at an obtuse angle. In this embodiment, the stubble-cutting blade 5 is positioned in the hopper 1 with the tail 52 stacked on the positioning sidewall 12, thereby initially positioning the stubble-cutting blade 5.

[0054] Please see Figures 1 to 4 As a specific embodiment of the stubble-cutting knife feeding machine structure provided in this application, the hopper 1 is provided with an insertion port 13, which is opposite to the tail end of the stubble-cutting knife 5 that is attached to the positioning side wall 12; the pusher 21 is adapted to be inserted from the insertion port 13 and abut against the tail end of the stubble-cutting knife 5.

[0055] In this embodiment, the size of the insertion port 13 is such that the pusher 21 can pass through. The pusher 21 is opposite to the tail end of the stubble-killing knife 5, so that the pusher 21 can push the tail end of the stubble-killing knife 5 after passing through the insertion port 13.

[0056] Please see Figure 1 , 3 As a specific embodiment of the stubble-removing knife feeding machine structure provided in this application, the ejection mechanism 2 also includes a fixed plate 22 and a first telescopic unit 24.

[0057] The fixing plate 22 is located on the outside of the hopper 1; the fixing plate 22 and the insertion port 13 form a receiving space 23, and the pusher 21 is located in the receiving space 23.

[0058] The first telescopic unit 24 is installed on the fixed plate 22; the first telescopic unit 24 is connected to the pusher 21 so as to drive the pusher 21 from the receiving space 23 into the hopper 1 through the insertion port 13.

[0059] In this embodiment, the pusher 21 is located in the receiving space 23. The first telescopic unit 24 drives the pusher 21, causing it to insert into the hopper 1 through the insertion port 13, thus completing the feeding. The first telescopic unit 24 can also drive the pusher 21 out of the insertion port 13 and back into the receiving space 23. In a specific implementation, the side of the fixing plate 22 is fixed to the hopper 1 by a support rod, so that a certain distance is maintained between the fixing plate 22 and the hopper 1 to form the receiving space 23. The first telescopic unit 24 can be a cylinder.

[0060] Please see Figure 2As a specific embodiment of the stubble-removing knife feeding machine structure provided in this application, the pusher 21 is plate-shaped, and the pusher 21 and the tail 52 of the stubble-removing knife 5 that abuts against the positioning side wall 12 are on the same plane; on the plane where the tail 52 of the stubble-removing knife 5 is located, the tail end of the stubble-removing knife 5 has a protruding area 521, and the pusher 21 has a recessed area 21 at the pusher tip; the protruding area 521 is opposite to the recessed area 21 and is suitable for being embedded in the recessed area 21.

[0061] In this embodiment, when the pusher 21 pushes the stubble-cutting knife 5, the protruding area 521 at the tail end of the stubble-cutting knife 5 is embedded in the recessed area 21 at the pushing tip of the pusher 21, thereby positioning the stubble-cutting knife 5 and preventing the stubble-cutting knife 5 from shifting in the width direction of the tail 52 during the pushing process. Figure 2 The up and down directions in the middle.

[0062] In practice, the plate-shaped pusher 21 is parallel to the positioning sidewall 12 and moves horizontally in a direction parallel to the positioning sidewall 12, precisely pushing the stubble-removing blade 5 that is against the positioning sidewall 12. On the plane where the tail 52 of the stubble-removing blade 5 is located, the tail end of the stubble-removing blade 5 is cut into an arc-shaped protrusion 521; the pusher 21 and the tail 52 of the stubble-removing blade 5 against the positioning sidewall 12 are on the same plane, and the pushing tip of the pusher 21 is opposite to the tail end of the stubble-removing blade 5. On the plane where the tail 52 of the stubble-removing blade 5 is located, the pushing tip of the pusher 21 is cut into a recessed area 21 with a V-shaped or inverted trapezoidal notch. In use, the recessed area 21 of the pushing tip of the pusher 21 is opposite to the protrusion 521 of the stubble-removing blade 5 against the positioning sidewall 12.

[0063] Please see Figure 1 , 3 In embodiment 4, as a specific implementation of the stubble-cutting knife feeding machine structure provided in this application, the hopper 1 is provided with a telescopic pressure head 14, which presses the blade tails 52 of each stubble-cutting knife 5 against the positioning side wall 12.

[0064] In this embodiment, the telescopic pressure head 14 is used to press the blade tails 52 of each stubble-cutting blade 5 against the positioning sidewall 12, so that after the pushing member 21 pushes out the stubble-cutting blade 5 that is against the positioning sidewall 12, the remaining stubble-cutting blades 5 can be pressed against the positioning sidewall 12 again under the push of the telescopic pressure head 14.

[0065] In a practical implementation, the telescopic pressure head 14 can be composed of a second telescopic unit and a pressure head. The second telescopic unit applies a certain pressure to the multiple stubble-removing knives 5 stacked on the positioning sidewall 12 through the pressure head. More specifically, the second telescopic unit can be a cylinder.

[0066] Please see Figure 1 , 3As a specific embodiment of the stubble-cutting knife feeding machine structure provided in this application, the stubble-cutting knife feeding machine structure also includes a positioning sensor 4, which is located at the end of the guide plate 3 away from the discharge port 11 and is adapted to detect the blade head 51 of the stubble-cutting knife 5.

[0067] In this embodiment, the positioning sensor 4 detects the blade head 51 of the stubble-cutting knife 5 to determine whether the stubble-cutting knife 5 is in place, thereby improving the feeding accuracy.

[0068] In practical implementation, the positioning sensor 4 can detect the blade head 51 of the stubble-cutting blade 5 to control whether the ejection mechanism 2 continues to push the stubble-cutting blade 5. More specifically, if the positioning sensor 4 does not detect the blade head 51 of the stubble-cutting blade 5, the ejection mechanism 2 continues to push the stubble-cutting blade 5; when the positioning sensor 4 detects the blade head 51 of the stubble-cutting blade 5, it controls the ejection mechanism 2 to stop pushing the stubble-cutting blade 5. The positioning sensor 4 can be a through-beam sensor, proximity sensor, etc., to detect the blade head 51 of the stubble-cutting blade 5.

[0069] This application embodiment also provides a welding device, which includes: the stubble-removing knife feeding machine structure of any of the above.

[0070] The welding equipment provided in this application avoids the problems of high labor intensity, low efficiency, and difficulty in ensuring feeding accuracy of manual feeding by adopting the stubble-removing knife feeding machine structure of any of the above.

[0071] In practice, the welding equipment can use a clamp to hold the stubble-removing knife 5, which is adsorbed and positioned by the guide plate 3, to ensure the stability of the welding process; alternatively, the welding head can be used directly to weld the stubble-removing knife 5, which is adsorbed and positioned on the guide plate 3, without the need for a clamp. The welding equipment can clamp the stubble-removing knife 5 with a clamp before welding. This can be done by clamping the stubble-removing knife 5 in situ on the guide plate 3 and then welding it directly, or by using a clamp to remove the stubble-removing knife 5 from the guide plate 3, adjusting its position, and then welding.

[0072] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
