Description

Technical Field

[0001] This utility model relates to the field of hole punching technology, specifically a rapeseed hole-planting positioning hole punch. Background Technology

[0002] When rapeseed is planted in cold regions, in order to improve soil temperature and humidity conditions and ensure the germination of rapeseed seeds and the growth of seedlings, a layer of heat-insulating film is generally covered on the planting site to achieve the dual effect of soil heat preservation and moisture retention, laying the foundation for rapeseed growth.

[0003] In the rapeseed hole-sowing process, a toothed hole punch is required. The saw teeth cut through the insulation film and insert into the soil to form a hole, providing a fixed position for seed sowing. However, in actual drilling operations, it was found that the insulation film fragments cut during the drilling process tend to accumulate and adhere to the inner side of the hole punch due to friction and adsorption with the upper part of the hole punch, as well as the stickiness caused by changes in soil temperature.

[0004] As the adhesive insulation film accumulates and thickens, it directly hinders the hole punch from penetrating deeper into the soil. This results in the subsequent hole punching depth failing to reach the appropriate depth required for rapeseed sowing, affecting the consistency of seed planting depth and potentially reducing seed germination rate. To ensure the punching effect, workers need to frequently stop the machine to clean the insulation film inside the hole punch. However, because the hole punch has a serrated design with sharp serrated edges to ensure the ability to break the film, cleaning is not only difficult to operate and hard to completely remove the adhesive film, but also easy to cut hands with the serrated edges. This increases labor intensity and reduces the efficiency of hole sowing operations, causing many inconveniences for rapeseed hole sowing in cold regions.

[0005] Therefore, a rapeseed hole-planting positioning punch is proposed to address the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a rapeseed hole-planting positioning punch to solve the problems mentioned in the background art.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0032] Please see Figures 1-6 This utility model provides a technical solution:

[0033] A rapeseed hole-planting positioning punch includes a force-applying rod 1, with a film-breaking punching mechanism 2 welded and fixed to the bottom end of the force-applying rod 1. The film-breaking punching mechanism 2 includes a connecting cylinder 21, with a serrated punching cylinder 23 hinged to the connecting cylinder 21 via a connecting piece 22. An operating cavity 24 is opened on one side of the top of the serrated punching cylinder 23. A film-collecting component 25 is installed inside the connecting cylinder 21, and a U-shaped limiting rod 26 is installed outside the film-collecting component 25. One end of the U-shaped limiting rod 26 extends to the inside of the connecting piece 22. The other end of the position rod 26 is welded and fixed with an operating rod 28. The front end of the operating rod 28 is fixedly connected with a pull rod 27. A support spring 29 is sleeved on the outer wall of the operating rod 28. The film collecting component 25 includes a film collecting rod 251. A prism 252 is fixed on one side of the film collecting rod 251. Multiple grooved anti-slip parts 253 arranged linearly are fixed on the outer side of the film collecting rod 251. A storage hole 254 is opened on the side of the grooved anti-slip part 253 near the pull rod 27. The pull rod 27 is embedded in the inner side of the storage hole 254.

[0034] As a further implementation of this solution, the outer side of the U-shaped limiting rod 26 is U-shaped, the front end of the U-shaped limiting rod 26 is an arc-shaped surface, the U-shaped limiting rod 26 is located outside the collecting rod 251, and the width of the inner side of the U-shaped limiting rod 26 is three times the diameter of the collecting rod 251.

[0035] To further explain, this structural design allows for smooth insertion into the connecting hole 223, achieving stable positioning of the connecting cylinder 21 and the serrated punching cylinder 23, ensuring synchronous movement of both during punching; on the other hand, the curved surface reduces resistance during insertion, making operation easier.

[0036] As a further implementation of this solution, a tapered member 255 is fixed to the bottom end of the collecting rod 251. The lower surface of the tapered member 255 has a tapered structure, and the diameter of the upper surface of the tapered member 255 is the same as the diameter of the grooved anti-slip member 253. The grooved anti-slip member 253 has an upward inclined structure. The length of the prism 252 is the same as the length of the collecting rod 251, and the prism 252 and the collecting rod 251 are parallel to each other. The cross-section of the prism 252 is triangular.

[0037] To further explain, the tapered part 255 at the bottom of the collecting rod 251 facilitates the insertion of the insulation film into the collecting rod 251, the grooved anti-slip part 253 tilts upward to effectively prevent the insulation film from moving downward, and the triangular cross-section of the prism 252 can quickly cut the accumulated insulation film during cleaning.

[0038] As a further implementation of this solution, the connector 22 includes a connector block 221 and a connector seat 222. The connector block 221 is fixedly disposed on the side of the connector cylinder 21 away from the positioning seat 3. The connector seat 222 is hinged to the outside of the connector block 221. The connector seat 222 is fixedly connected to the top of the serrated punched cylinder 23 on the side away from the operating cavity 24. Both the connector seat 222 and the serrated punched cylinder 23 are provided with connector holes 223 for adapting to the U-shaped limiting rod 26.

[0039] Specifically, when cleaning or maintenance is required, the sawtooth punching cylinder 23 can be easily rotated out from under the connecting cylinder 21, which not only avoids the safety hazards caused by the sawtooth, but also facilitates the operation of the internal components.

[0040] As a further implementation of this solution, a positioning seat 3 is welded and fixed on the outer wall of the connecting cylinder 21 near the operating cavity 24. The positioning seat 3 is located above the operating cavity 24. The inner side of the positioning seat 3 is slidably connected to the operating rod 28. The other end of the support spring 29 is fixedly connected to the operating rod 28 to provide elastic force for the U-shaped limiting rod 26 so that it can be stably inserted into the connecting hole 223.

[0041] Specifically, the positioning seat 3 provides a sliding guide for the operating rod 28 to ensure its stability of movement, and the support spring 29 provides elasticity for the U-shaped limiting rod 26 to ensure its stable insertion into the connecting hole 223.

[0042] As a further implementation of this scheme, reinforcing arms 4 are welded and fixed on both sides of the bottom of the force-applying rod 1. The reinforcing arms 4 have an arc-shaped structure and are not easily scratched. The bottom end of the reinforcing arms 4 is welded and fixed to the top of the connecting cylinder 21. This arrangement is used to improve the firmness of the connection between the force-applying rod 1 and the connecting cylinder 21.

[0043] Work process: In the initial state of the component, the U-shaped limiting rod 26 is stably inserted into the connecting hole 223 of the connecting seat 222 and the sawtooth punching cylinder 23 under the influence of the elastic force of the supporting spring 29. At this time, the connecting cylinder 21 and the sawtooth punching cylinder 23 are in a fixed state and cannot be rotated. The axes are on the same straight line. The film collecting rod 251 and other components of the film collecting component 25 are in a suitable position inside the sawtooth punching cylinder 23. The operator holds the force applying rod 1 and applies a downward force to the connecting cylinder 21. The force is transmitted to the connecting cylinder 21 through the reinforcing arm 4, so that the connecting cylinder 21 drives the sawtooth punching cylinder 23 to move downward synchronously.

[0044] As the saw teeth at the lower end of the saw-toothed perforating cylinder 23 move downwards, they cut the insulation film and insert it into the soil to form the holes required for rapeseed sowing. The cut insulation film, along with the soil, enters the inner side of the saw-toothed perforating cylinder 23 and is located below the operating chamber 24. The insulation film is guided by the conical part 255 of the film collecting part 25 and is fitted onto the film collecting rod 251 and the pull rod 27. Because the grooved anti-slip part 253 has an upward inclined structure, the inserted insulation film cannot move downwards, which can prevent the insulation film from accidentally falling off during subsequent soil removal operations. During continuous perforation operations, the film collecting part 25 continuously accumulates the insulation film and squeezes it into the area of ​​the operating chamber 24 for storage.

[0045] After a period of operation, the thickness of the insulation film collected by the collecting device 25 is observed through the operating cavity 24. If cleaning is required, subsequent operations are performed. The operator pulls the operating rod 28 outward, which moves the U-shaped limiting rod 26 and the pull rod 27 synchronously. At this time, the U-shaped limiting rod 26 gradually disengages from the limiting of the connecting hole 223, and the pull rod 27 also moves out of the receiving hole 254, pulling the insulation film collected on the collecting rod 251 to move together. The accumulated insulation film, affected by the tension, comes into contact with the tip of the prism 252 on one side of the collecting rod 251. Since the prism 252 has a triangular cross-section and is relatively sharp, it can cut the accumulated insulation film at the contact point, allowing the accumulated insulation film to quickly detach from the collecting rod 251, facilitating centralized processing of the insulation film and avoiding pollution.

[0046] As the U-shaped limiting rod 26 completely disengages from the connecting hole 223, the sawtooth punching cylinder 23 can rotate around the hinge point of the connecting piece 22, thereby moving out from under the connecting cylinder 21. This avoids the potential danger caused by the sawtooth of the sawtooth punching cylinder 23 and facilitates separate maintenance of the film collecting piece 25 and the sawtooth punching cylinder 23, such as cleaning residual soil and checking the wear of the sawtooth.

[0047] After cleaning and maintenance, rotate the serrated punching cylinder 23 back below the connecting cylinder 21 so that the connecting hole 223 is aligned with the U-shaped limiting rod 26. Release the operating rod 28, and the operating rod 28 will reset under the elastic force of the support spring 29, causing the U-shaped limiting rod 26 to be reinserted into the connecting hole 223, so that the connecting cylinder 21 and the serrated punching cylinder 23 are fixed again, ready for the next punching operation.

[0048] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
