Description

Technical Field

[0001] The utility model relates to the technical field of weeding tools, in particular to a portable weeding device for substrate cultivation. Background Art

[0002] Substrate cultivation is a common cultivation form in modern agricultural production, that is, using peat, vermiculite, coconut bran fiber, straw particles and other substrates for cultivation, or adding these substrates to traditional soil to improve the physical and chemical properties of the soil, thereby promoting the growth of crops and achieving high-quality and efficient production of crops. Since peat, vermiculite, coconut bran fiber, straw particles and other substrates have a small bulk density, loose texture and good air permeability, they can avoid the problem of crop root hypoxia caused by soil compaction and promote crop growth and development. However, weeds will grow in the soil and seriously affect the normal growth of crops, so weeds need to be removed.

[0003] An existing portable weeding device for substrate cultivation (Announcement No.: CN219228317U) has the following defects: the above device uses a shovel head to insert into the soil to remove the roots of weeds, but since there is only a single shovel head that can only be inserted obliquely from one side of the weed to the root of the weed and cut it off, the shovel head can only be rotated when pulling out the weeds, so that the shovel head turns over the entire soil, thereby causing large-scale damage to the soil, and if the weeds are too close to the plants, the plants will be damaged. For this reason, the present utility model is proposed. Utility Model Content

DETAILED DESCRIPTION

[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Please see attached Figure 1 -Attached Figure 4 A portable weeding device for substrate cultivation comprises a main rod 1, a fixing plate 101 is fixed at the bottom end of the main rod 1, a weeding assembly is arranged on the outer wall of the main rod 1 and the bottom surface of the fixing plate 101, the weeding assembly comprises a movable plate 2 movably sleeved on the outer wall of the main rod 1, two oblique pressure rods 201 are arranged below the movable plate 2, a blade 202 is fixed at the bottom end of the oblique pressure rod 201, two adjusting holes 203 are arranged on the top surface of the fixing plate 101, an adjusting plate 206 is arranged inside the adjusting hole 203, an oblique hole 207 is arranged on the top surface of the adjusting plate 206, and the oblique pressure rod 201 and the inner part of the oblique hole 207 are inserted.

[0022] In the embodiment, a sliding groove 204 is provided on the bottom surface of the movable plate 2, and a directional wheel 205 is slidably provided inside the sliding groove 204. The top end of the oblique pressure rod 201 is fixed to the bottom surface of the directional wheel 205. By providing two inclined oblique pressure rods 201, when the oblique pressure rod 201 is pressed down, the two blades 202 are driven to approach each other, so that the blades 202 are inserted into the soil on both sides of the weeds and penetrate deep, converge at the roots of the weeds and cut off the roots of the weeds, and then the main rod 1 can be pulled to bring out the soil on both sides of the weed roots, so that there is no need to turn over the soil to pull out the weeds, thereby preventing large-scale damage to the soil and not affecting the plants around the weeds, thereby ensuring the normal growth of the plants.

[0023] In the embodiment, the internal thread connection of the main rod 1 is connected with the threaded rod 3, the top of the threaded rod 3 is fixed with a holding rod 301, the outer wall of the threaded rod 3 is threadedly connected with a locking nut 302, and by rotating the threaded rod 3, the threaded rod 3 is threadedly connected with the threaded rod 3, so that the threaded rod 3 is contracted toward the inside or extended outward, so that the staff can adjust the overall length of the threaded rod 3 and the main rod 1 as needed.

[0024] In the embodiment, a pedal 4 is fixed to the front side of the movable plate 2, and an anti-slip pattern 401 is provided on the top surface of the pedal 4. Through the setting and use of the pedal 4, it is convenient for the staff to better press down the movable plate 2, so that the blade 202 can be better inserted into the soil, which is convenient for better weeding.

[0025] In the embodiment, a plurality of locking holes 5 are provided on the front and rear sides of the fixing plate 101, and the locking holes 5 are communicated with the inside of the adjusting hole 203. A threaded hole 501 is provided on the front and rear sides of the adjusting plate 206, and a bolt 502 is inserted into the inside of the locking hole 5 corresponding to the position of the threaded hole 501, and the bolt 502 is threadedly connected with the threaded hole 501. By adjusting the position of the adjusting plate 206 in the adjusting hole 203 and then locking it with the bolt 502, the distance between the two blades 202 can be adjusted according to the size of the weeds, so as to better cut the roots of the weeds.

[0026] In the embodiment, two limit grooves 6 are provided on the front and rear sides of the adjustment hole 203, and two limit bars 601 are fixed on the front and rear sides of the adjustment plate 206. The limit bars 601 and the limit grooves 6 are internally slidingly arranged. By setting the limit bars 601 and the limit grooves 6 internally slidingly arranged, the adjustment plate 206 can be limited to prevent the adjustment plate 206 from falling out of the adjustment hole 203 when the bolt 502 is loosened.

[0027] Working principle: When in use, the bolt 502 is removed from the locking hole 5 and the threaded hole 501, and then the position of the adjustment plate 206 in the adjustment hole 203 is adjusted to adjust the distance between the two blades 202 according to the size of the weeds, and then locked by the bolt 502. At this time, by rotating the threaded rod 3, the threaded rod 3 is threadedly connected to the threaded rod 3, so that the threaded rod 3 is retracted toward the inside of the threaded rod 3 or extended outward, so that the staff can adjust the overall length of the threaded rod 3 and the main rod 1 as needed, and then the staff will place the two blades 202 on the soil on both sides of the weeds, and then use the foot to When the pedal 4 is stepped on, the two oblique pressure rods 201 are driven to slide inside the oblique hole 207, so that the inserting blade 202 is inserted into the soil. As the oblique pressure rod 201 descends, the directional wheel 205 at the top of the oblique pressure rod 201 slides inside the sliding groove 204. Then, when the two inserting blades 202 meet in the soil, the roots of the weeds can be cut off. Then, the main rod 1 can be pulled so that the soil on both sides of the weed roots can be brought out. By setting the limiting strip 601 and the internal sliding setting of the limiting groove 6, the adjusting plate 206 can be limited to prevent the adjusting plate 206 from falling out of the adjusting hole 203 when the bolt 502 is loosened.

[0028] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
