Description

Technical Field

[0001] This utility model relates to the field of weeding technology, and in particular to a weeding rake for raising jujube seedlings. Background Technology

[0002] For the cultivation of *Ziziphus jujuba* seedlings, high-quality seeds should be selected and soaked before sowing in fertile, well-drained soil. Maintaining suitable humidity and temperature promotes germination and growth. A weed rake with sturdy metal teeth effectively loosens the soil and removes weeds, providing a healthy growing environment free from weed competition for the seedlings and promoting their healthy growth. Regularly using a weed rake to clear weeds in the *Ziziphus jujuba* nursery not only reduces the labor required for manual weeding but also improves soil aeration and water permeability, helping to increase the survival rate and growth rate of the seedlings.

[0003] When working in an environment with dense weeds, the metal teeth of the weed rake are easily tangled and clogged by weeds. This not only reduces weeding efficiency but also requires the user to frequently stop their work to manually remove the weeds between the teeth. Interruptions are not only time-consuming and laborious but also greatly affect the continuity and efficiency of the work, causing additional physical burden to the user. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, the purpose of this utility model is to provide a weeding rake for raising jujube seedlings.

[0005] A weeding rake for raising jujube seedlings includes a first handle, a fixing plate, blades, a sliding rod, a connecting block, and blades. The fixing plate is connected to one end of the first handle. At least seven blades are connected to the bottom of the fixing plate. The sliding rod is slidably connected to the side of the fixing plate near the first handle. Both ends of the sliding rod are inclined upwards. A connecting block is connected to each sliding rod. Blades are connected to the bottom of each connecting block. The blades are slidably connected to the blades. The blades are aligned with the gaps between adjacent blades and are higher than the blades.

[0006] Furthermore, the gaps between adjacent cutting teeth are all arc-shaped.

[0007] Furthermore, it also includes a limit plate, with a limit plate connected to the right side of each blade tooth, and the limit plate is located on the side of the blade tooth closer to the first grip.

[0008] Furthermore, it also includes a hinge, a second grip, pressure bars, and a scraping assembly. The first grip is connected to the hinge, and the second grip is hinged to the hinge. Two pressure bars are connected to the end of the second grip near the fixed plate. The scraping assembly is connected to the fixed plate, and the pressure bars are in contact with the scraping assembly.

[0009] Furthermore, the scraping assembly includes a scraper, guide rods, and a helical spring. The upper and lower sides of the fixed plate are open, and the scraper is slidably connected inside the opening of the fixed plate. The scraper contacts the left side of the blade teeth. Two guide rods are connected to the fixed plate, and the scraper is slidably connected to the guide rods. A helical spring is connected between the scraper and the guide rods.

[0010] Furthermore, the scraping assembly also includes a torsion spring, and a torsion spring is connected between the hinge and the second grip.

[0011] The beneficial effects are as follows: This utility model is equipped with a sliding rod, a connecting block, a blade, and a limiting plate. By repeatedly striking the limiting plate with the blade, the weeds are ensured to be completely cut, avoiding the problem of reduced weeding efficiency due to weeds tangling and clogging. There is no need to frequently stop weeding to manually clean the blade teeth, which can greatly reduce labor intensity and improve the continuity of weeding operation. It is also equipped with a scraper, which can thoroughly scrape off the cut weed residue from the surface of the blade teeth, ensuring that weeds no longer entangle on the blade teeth.

Detailed Implementation

[0017] The technical solution of this utility model will be further described below with reference to the accompanying drawings.

[0018] A type of weed rake used for raising jujube seedlings, such as Figures 1-4As shown, the assembly includes a first grip 1, a fixing plate 2, blade teeth 3, a sliding rod 4, a connecting block 5, a blade 6, a limiting plate 7, a hinge 101, a second grip 8, a pressure rod 9, and a scraping assembly. One end of the first grip 1 is connected to the fixing plate 2. At least seven blade teeth 3 are connected to the bottom of the fixing plate 2. A sliding rod 4 is slidably connected to the side of the fixing plate 2 near the first grip 1. Both ends of the sliding rod 4 are inclined upwards. Connecting blocks 5 are connected to each sliding rod 4. Blades 6 are connected to the bottom of each connecting block 5. The blades 6 are slidably connected to the blade teeth 3 and to adjacent blades. The gaps between the teeth 3 are aligned, and the blade 6 is higher than the teeth 3. The gaps between adjacent teeth 3 are all arc-shaped to reduce right angles or sharp edges, making it less likely for weeds to get tangled on the teeth 3. Each tooth 3 is connected to a limiting plate 7 on its right side. The limiting plates 7 are all located on the side of the tooth 3 near the first grip 1. The first grip 1 is connected to a hinge 101, and a second grip 8 is hinged to the hinge 101. Two pressure rods 9 are connected to the end of the second grip 8 near the fixed plate 2. A scraping component is connected to the fixed plate 2, and the pressure rods 9 are in contact with the scraping component.

[0019] like Figure 1 , Figure 3 and Figure 4 As shown, the scraping assembly includes a scraper 10, a guide rod 11, a helical spring 12, and a torsion spring 13. The upper and lower sides of the fixing plate 2 are open, and the scraper 10 is slidably connected inside the opening of the fixing plate 2. The scraper 10 contacts the left side of the blade teeth 3. Two guide rods 11 are connected to the fixing plate 2, and the scraper 10 is slidably connected to the guide rods 11. A helical spring 12 is connected between the scraper 10 and the guide rods 11. A torsion spring 13 is connected between the hinge 101 and the second grip 8.

[0020] Initially, both the helical spring 12 and the torsion spring 13 are in their natural state, the scraper 10 is away from the blade teeth 3, the end of the second grip 8 near the fixed plate 2 is tilted upwards, and the pressure rod 9 is in contact with the top of the scraper 10. During weeding, both hands hold the first grip 1, and the weeding rake is used in a traditional manner. When weeds become entangled on the blade teeth 3, the first grip 1 rotates the rake 90 degrees, causing one end of the sliding rod 4 to strike the ground, making the sliding rod 4 slide on the fixed plate 2. The fixed plate 2, through the connecting block 5, drives the blade 6 to move and strike the limiting plate 7. During the strike of the blade 6 against the limiting plate 7, the weeds between adjacent blade teeth 3 are cut by the blade 6. Then, the other end of the sliding rod 4 strikes the ground, causing the sliding rod 4 to slide in the opposite direction on the fixed plate 2, and the blade 6 moves in the opposite direction... The blade 6 strikes the adjacent limiting plate 7 repeatedly, ensuring that the weeds are completely cut off. This avoids the problem of reduced weeding efficiency due to weed entanglement and blockage. It eliminates the need to frequently stop weeding to manually clean the blade teeth 3, greatly reducing labor intensity and improving the continuity of weeding operations. Then, the second grip 8 is pressed down, causing the torsion spring 13 to deform. The second grip 8 rotates, causing the pressure rod 9 to press the scraper 10. The scraper 10 slides downward along the guide rod 11, thereby scraping off the cut weeds. The second grip 8 is released, and the torsion spring 13 returns to its original state, causing the second grip 8 to reverse and reset. The spiral spring 12 returns to its original state, causing the scraper 10 to slide upward along the guide rod 11 and reset. The scraper 10 scrapes the weeds off the blade teeth 3 multiple times.

[0021] Those skilled in the art should understand that the above embodiments do not limit the present invention in any way, and all technical solutions obtained by means of equivalent substitution or equivalent transformation fall within the protection scope of the present invention.
