Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, specifically a device for hilling up the roots of rapeseed to prevent frost damage and lodging. Background Technology

[0002] Rapeseed is susceptible to frost damage and lodging in winter. Traditional manual hilling and root mounding are inefficient. In the existing technology, traditional hilling equipment can only complete soil turning and hilling operations. Fertilization requires manual labor or additional equipment, resulting in a fragmented work process. Furthermore, repeated field compaction exacerbates soil compaction.

[0003] For example, the authorized patent document with application number CN202322127729.2 discloses a rapeseed seedling support and soil-raising machine. This utility model relates to the field of agricultural equipment technology. Support rods are respectively movably installed on the left and right sides of the frame. A first slider is fixedly installed on the upper part of the support rod. The slider is slidably installed in a first groove opened in the frame. A first threaded rod is screwed onto the frame through a bearing, and the first threaded rod is screwed onto two first sliders through a thread. The two ends of the first threaded rod have opposite thread directions. The seedling support rods are set in pairs at the lower part of the two support rods. The seedling support rods are inclined downward at the front end. While raising the soil of rapeseed, it can also support the seedlings. This not only avoids splashed soil covering the rapeseed, but also improves work efficiency.

[0004] The aforementioned patents have issues with the lack of fertilization function in the soil-building equipment, and the inability to accurately control the fertilization switch. Therefore, we need to provide a device for soil-building, root protection, frost prevention, and lodging resistance for rapeseed. Utility Model Content

[0025] 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.

[0026] Please see Figure 1-6 This utility model provides a technical solution: a device for hilling up the roots of rapeseed to prevent frost damage and lodging, comprising:

[0027] The outer shell 1, fertilizer tank 2, soil separating plate 3, and fertilization mechanism 4 are provided. The outer shell 1 contains a fertilizer tank 2 filled with fertilizer liquid. The outer shell 1 contains a fertilization mechanism 4 for blocking and opening the liquid outlet at the bottom of the fertilizer tank 2. The surface of the outer shell 1 is provided with a soil separating plate 3 for soil filling.

[0028] The fertilizer application mechanism 4 includes a feeding pipe 41, a piston 42, a drain pipe 43, and a pulling member 44. The feeding pipe 41 is connected to the bottom of the fertilizer tank 2. The piston 42 is used to seal the feeding pipe 41. The outer shell 1 is provided with a pulling member 44 for moving the piston 42. One side of the feeding pipe 41 is connected to an inclined drain pipe 43. One end of the drain pipe 43 passes through one side of the outer shell 1 and extends outward.

[0029] Specifically, the soil separating plate 3 includes a soil separating plate and a mounting frame. The soil separating plate and the mounting frame are welded and fixed, and one side of the mounting frame is welded to the surface of the outer shell 1. The outer shell 1 is made of metal. By pulling the outer shell 1 to mound soil in the field, the soil separating plate separates the soil and piles it around the rapeseed, thus achieving soil mounding. In its natural state, the piston 42 blocks the discharge pipe 41 and seals the bottom of the fertilizer tank 2. By adjusting the pulling part 44, the piston 42 can be moved downward, causing the piston 42 to separate from the discharge pipe 41. At this time, the piston 42 is still inside the discharge pipe 41, but the fertilizer can flow out through the drain pipe 43, thus achieving the fertilization operation. The piston 42 is fitted with a rubber ring that fits against the inner wall of the discharge pipe 41, similar to the rubber block inside a syringe. The rubber ring on the surface of the piston 42 fits tightly against the inner wall of the discharge pipe 41, which has a leak-proof effect, allowing the fertilizer to flow out only through the drain pipe 43.

[0030] The soil-spreading plate 3 first loosens the soil and opens the trench, followed by the drainage pipe 43 to apply fertilizer, ensuring that the fertilizer covers the loosened soil area and improves absorption efficiency. The fertilizer application mechanism 4 works in coordination with the soil-covering component to avoid the problem of uncoordinated operation caused by the split design of traditional equipment.

[0031] A rubber ring 5 is fixedly installed on the inner wall of the feed pipe 41. A tapered groove 6 adapted to the tapered part at the top of the piston 42 is opened at the bottom of the rubber ring 5. A guide cylinder 7 for guiding the piston 42 is provided on the inner wall of the outer shell 1.

[0032] Furthermore, the tapered groove 6 at the bottom of the rubber ring 5 is adapted to the tapered top of the piston 42. When the piston 42 moves upward under the push of the pulling member 44, the tapered top of the piston 42 fits tightly with the bottom of the rubber ring 5. Since the rubber ring 5 is made of rubber, it can deform to a certain extent and achieve a better sealing effect. The surface of the piston 42 is movably connected to the guide cylinder 7, which restricts the vertical movement of the piston 42. The bottom of the guide cylinder 7 is equipped with an exhaust control for venting air.

[0033] The conical seal between piston 42 and feed pipe 41 ensures zero leakage when closed, preventing fertilizer dripping, and the inner wall of guide cylinder 7 is coated with Teflon, resulting in a friction coefficient as low as 0.04.

[0034] The pulling component 44 includes a pull rod 441, a rack 442, a spring 443, a gear 444, and a column 445. The pull rod 441 is hinged to the annular protrusion on the surface of the piston 42. One end of the pull rod 441 is hinged to the rack 442, which meshes with the gear 444. A spring 443 is provided between the rack 442 and the inner wall of the outer casing 1. The column 445 at the axis of the gear 444 is rotatably installed inside the outer casing 1.

[0035] It is worth noting that the rotation of the column 445 drives the gear 444 to rotate, and the surface of the gear 444 meshes with the rack 442, thereby causing the rack 442 to move. Since one end of the rack 442 is hinged to the pull rod 441, the pull rod 441 swings, thereby dragging the piston 42 downward. At this time, the spring 443 is in a compressed state, and the piston 42 moves downward to realize the fertilizer dispensing. In the natural state, the spring 443 keeps squeezing the rack 442, causing the piston 42 to block the discharge pipe 41 and not discharge fertilizer. The elastic coefficient of the spring 443 can make the piston 42 press the rubber ring 5 tightly, which will not cause leakage.

[0036] It also includes a transmission component 8 for rotating the column 445. The transmission component 8 includes a wire rope 81, a winding reel 82 and a long tube 83. The winding reel 82 is fixedly installed on the surface of the column 445. The long tube 83 is connected to the inside of the outer casing 1. The wire rope 81 on the surface of the winding reel 82 passes through one end of the long tube 83 and is equipped with a handle.

[0037] It is worth noting that the steel wire rope 81 is moved inside the long tube 83 by pulling the handle. The top of the long tube 83 is welded with a handle to facilitate dragging the outer shell 1. The movement of the steel wire rope 81 will drive the winding reel 82 to rotate. The winding reel 82 is fixed to the surface of the column 445. The column 445 is rotatably installed inside the outer shell 1, thereby adjusting the rotation of the column 445 to start the fertilization operation.

[0038] The inner wall of the long tube 83 has a self-lubricating coating, allowing it to move flexibly even at -40℃. The steel wire rope 81 is made of 316 stainless steel and PTFE, making it resistant to fertilizer corrosion.

[0039] The inner wall of the outer shell 1 is provided with a guide wheel 9 for auxiliary support of the wire rope 81, and the bottom of the long tube 83 located inside the outer shell 1 is provided with a smooth ring 10.

[0040] The guide wheel 9 has an annular groove on its surface to assist in limiting the wire rope 81. The guide wheel 9 provides auxiliary support for the wire rope 81 and reduces friction, further protecting the surface of the wire rope 81 and extending its service life. A smooth ring 10 is located at the lower end of the long tube 83, which also protects the wire rope 81. The surface roughness of the smooth ring 10 is Ra≤0.2μm (mirror grade). The wheel body is coated with polyurethane to absorb the vibration energy of the wire rope 81.

[0041] A guide rod 11 is movably sleeved inside the spring 443, and a guide groove 12 is provided inside the rack 442 that is slidably installed with the guide rod 11. One end of the guide rod 11 is fixedly installed on the inner wall of the outer shell 1.

[0042] Specifically, the guide rod 11 and the guide groove 12 form a sliding pair, which restricts the motion freedom of the rack 442 to a single direction, completely solving the "snake-like swing" problem common in traditional spring 443 mechanisms. The spring 443 is always compressed along the center line, avoiding fatigue fracture caused by non-axial force. The surface of the guide rod 11 is plated with hard chrome (hardness HRC62), which is resistant to fertilizer corrosion.

[0043] The top of the fertilizer tank 2 is connected to a feed pipe 13 with a sealed cap, and the fertilizer tank 2 is designed to be a transparent tank.

[0044] The liquid fertilizer is poured directly into the feed pipe 13 by opening the sealed cap. The fertilizer level can be observed in real time through the transparent barrel wall. The inner wall has a smooth coating to accommodate fertilizers with a pH value of 2-12. There are also tiny vent holes on the top of the fertilizer barrel 2 (not described in the text).

[0045] A support wheel 14 is provided on one side of the outer casing 1, and a protective cover 15 is provided on one side of the outer casing 1 to protect the liquid outlet end of the drain pipe 43;

[0046] A perforated protective cover 15 is provided, with the perforations far away from the soil separating plate to prevent soil from clogging the lower end of the drainage pipe 43. Support wheels are also provided to facilitate the movement of the outer shell 1. The perforations are located on the side and bottom of the protective cover 15, avoiding the direction of soil dispersal from the soil separating plate. The perforations are made of 304 stainless steel with laser cutting, which is resistant to salt and alkali corrosion. The support wheel set meets the needs of all-terrain operations, including paddy fields, dry fields, and slopes.

[0047] This device achieves soil mounding by pulling the outer casing 1 in the field. A soil separating board separates the soil and piles it around the rapeseed. A handle pulls a steel wire rope 81, which moves within a long tube 83. The top of the long tube 83 has a handle for easy dragging of the outer casing 1. The movement of the steel wire rope 81 causes the winding reel 82 to rotate. The winding reel 82 is fixed to the surface of a column 445, which is rotatably mounted inside the outer casing 1. This allows for adjustment of the column 445's rotation. The rotation of the gear 444 drives the gear 444 to rotate, and the surface of the gear 444 meshes with the rack 442, thereby causing the rack 442 to move. Since one end of the rack 442 is hinged to the pull rod 441, the pull rod 441 swings, thereby dragging the piston 42 downward. At this time, the spring 443 is in a compressed state, the piston 42 moves downward, and the piston 42 separates from the feed pipe 41. At this time, the piston 42 is still located in the feed pipe 41, but the fertilizer can flow out through the drain pipe 43, thereby achieving the fertilization 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.
