Description

Technical Field

[0001] The present application relates to the technical field of tools, and in particular to a scarifier. Background Art

[0002] Field cultivation, greenhouse planting, and small-scale vegetable gardens, orchards, nurseries, tea gardens, lawns, and other occasions require regular soil loosening to allow crops to absorb sufficient oxygen in the soil. Traditional soil looseners are large and noisy, making them inconvenient to carry and unable to till the soil of smaller areas of land. In addition, existing lawn soil looseners use soil pegs to loosen the grass by inserting and removing them. For example, Chinese utility model patent application number CN202420341026.1 discloses a portable soil loosener that uses soil pegs to achieve the effect of inserting and removing soil, but it cannot loosen the soil continuously. Moreover, when loosening the soil, the user needs to visually determine the insertion and removal positions of the soil pegs, resulting in uneven soil loosening.

[0003] To solve the above problems, the Chinese utility model patent application number CN201922200457.8 discloses a gardening loosening device, which uses a rolling gear to roll on the ground, thereby achieving the effect of continuous and uniform loosening of the soil. However, since the plug-in and the connecting rod in this solution are both detachable connection structures, after long-term use, relative shaking will occur between the two, resulting in poor structural stability and short service life. In addition, the installation method of the toothed roller in this solution is complicated and the toothed roller cannot be quickly disassembled and assembled. In addition, the length of its operating rod cannot be carried, resulting in the problem of inconvenient operation during use, and there is also the problem of inconvenience in carrying due to the inability to further store it. Utility Model Content

[0004] In order to solve the problems of the existing tiller proposed in the above background technology, such as poor structural stability, short service life, inconvenient disassembly and assembly of the toothed roller, inconvenient operation of the operating lever, and inconvenience in carrying due to inability to be stored, the present application provides a tiller.

[0005] The present application provides a soil scarifier that adopts the following technical solution:

[0006] A soil scarifier, comprising:

[0007] A connecting member, one end of which has at least one support rod extending in a first direction of the connecting member, a rotatable loosening wheel being mounted on the end of the support rod, and a surface of the connecting member having at least one first concave cavity recessed downward;

[0008] The insertion rod is detachably mounted on the connecting member. After being mounted on the connecting member, the length direction of the insertion rod is consistent with the first direction of the connecting member. A rotatable loosening wheel is mounted on the end of the insertion rod. The surface of the insertion rod has at least one second concave cavity that is recessed downward.

[0009] The first handle is detachably mounted on an end of the connecting member away from the support rod, and the first handle is a telescopic structure.

[0010] By adopting the above technical solution, the soil is loosened by arranging loosening wheels at the ends of the support rod and the insertion rod, and the arrangement of the first cavity and the second cavity can further enhance the structural strength of the support rod and the insertion rod, and improve the structural stability during use. Since the support rod on the connecting member is integrally connected to the connecting member, the support rod will not shake, making the operation more stable and extending the service life of the loosener. The retractable first handle can facilitate adjustment of its overall length and can be stored when idle, reducing the problem of space occupancy and facilitating carrying and transportation.

[0011] Optionally, there are two support rods, and the insertion rod is detachably mounted on a connecting piece between the two support rods.

[0012] By adopting the above technical solution, it is possible to choose whether to install the support rods according to actual conditions; when it is necessary to loosen the soil on both sides of the crop, the rods can be disassembled, and the loosening wheels at the ends of the two support rods can be placed on both sides of the crop to avoid damage to the crop; when it is only necessary to loosen the soil, the rods are installed on the connecting parts to improve the uniformity of loosening the soil.

[0013] Optionally, the first concave cavity is respectively arranged on the upper and lower surfaces of the connecting member.

[0014] By adopting the above technical solution, the weight of the entire connecting piece can be reduced and materials can be saved, and the structural strength of the connecting piece can be improved. That is, the non-recessed structure on the surface of the connecting piece can form reinforcing ribs and rib structures, thereby improving the structural stability of the connecting piece.

[0015] Optionally, the second concave cavity is respectively arranged on the upper and lower surfaces of the insertion rod.

[0016] By adopting the above technical solution, the weight of the entire insertion rod can be reduced and materials can be saved, which is the same as the above effect. In this way, the non-depressed area on the surface of the insertion rod forms a reinforcing rib and rib structure, which is beneficial to improving the structural strength of the insertion rod.

[0017] Optionally, both sides of the front end of the support rod and the insertion rod have branches inclined outward, and the two branches form a V-shaped structure. The loosening wheel is sleeved on the V-shaped structure and is limited by a cotter pin installed at the end of the branch.

[0018] By adopting the above technical solution, the branch can be first inserted into the center hole of the loosening wheel, and the axis direction of the loosening wheel can be limited by the cotter pin, which has the characteristics of simple structure and convenient disassembly and assembly; in addition, since the two branches at the end of the support rod or the plug rod are in a V-shaped structure, after the two loosening wheels are installed on the branches, the two can form a certain angle, which is convenient for force balance.

[0019] Optionally, the loosening wheel has teeth extending outward and evenly distributed in the circumferential direction, the ends of the teeth form spikes, and the teeth on the two loosening wheels at the front end of the same support rod or the same insertion rod are staggered.

[0020] By adopting the above technical solution, the spike portion can be quickly inserted into the soil, and since the teeth of the two loosening wheels are staggered, the loosening effect can be improved and the uniformity of the loosening can be improved.

[0021] Optionally, the insertion rod and the first handle are both detachably mounted on the connecting member via a spring pin.

[0022] By adopting the above technical solution, the convenience of assembling and disassembling the insertion rod and the first handle can be improved, and the operation is simple and the connection is stable.

[0023] Optionally, the connecting piece is made of metal or alloy; and the insertion rod is made of nylon.

[0024] By adopting the above technical solution, the nylon rod has the characteristics of low cost, high structural strength and easy installation. Moreover, since it needs to be frequently held by hand for disassembly and assembly, the nylon material feels softer than metal, avoiding the cold feeling caused by the hand touching the metal, and providing a better experience.

[0025] Optionally, the first handle includes a plurality of short rods that are sequentially sleeved and can be connected end to end, and a plastic sleeve is installed at the end position of the short rod located on the outside of two adjacent sleeved short rods.

[0026] By adopting the above technical solution, since the adjacent short rods are arranged in a sleeve manner, the function of axial relative movement of the two adjacent short rods can be achieved, and then the effect of adjusting the overall length of the first handle can be achieved. The plastic sleeve can prevent the end of the short rod from forming a conical structure due to excessive force, thereby improving the structural strength of the end of the short rod.

[0027] Optionally, a second handle is further included, and the second handle is detachably connected to the insertion rod.

[0028] By adopting the above technical solution, the second handle is connected to the insertion rod alone, so that the insertion rod can be used alone. That is, in this state, the weight caused by the connection piece can be saved.

[0029] In summary, this application includes at least one of the following beneficial technical effects:

[0030] 1. The design structure of the utility model is simple and reasonable. It uses an integrally connected support rod structure at the end of the connecting piece to avoid the problem of shaking during use, and uses a detachable structure design of the plug rod to meet the loosening needs of different scenarios. It has the advantages of stable structure and wide application range.

[0031] 2. The loosening wheel of the utility model is sleeved on the branch and is limited by a cotter pin, which has the advantages of simple assembly structure, good limiting effect and easy disassembly and assembly.

[0032] 3. The utility model provides a concave structure on the surface of the connecting piece and the insertion rod, so as to improve the structural strength of the connecting piece and the insertion rod while reducing material costs, which is beneficial to extending the service life of the scarifier.

[0033] 4. The handle of the present invention is detachable and retractable, and can be disassembled into a multi-section structure, which is conducive to adjusting the length according to people of different heights, and can be stored when idle and easy to carry during transportation.

[0043] The present application is further described in detail below with reference to the accompanying drawings.

[0044] As shown in the figure, the embodiment of the present application discloses a scarifier, comprising:

[0045] The connecting member 2 has at least one support rod 202 extending in a first direction toward the connecting member 2 at one end, a rotatable loosening wheel 4 is mounted on the end of the support rod 202, and the surface of the connecting member 2 has at least one first concave cavity 201 that is recessed downward;

[0046] The rod 3 is detachably mounted on the connecting member 2. After being mounted on the connecting member 2, the length direction of the rod 3 is consistent with the first direction of the connecting member 2. A rotatable loosening wheel 4 is mounted on the end of the rod 3. The surface of the rod 3 has at least one second concave cavity 301 that is recessed downward.

[0047] The first handle 1 is detachably mounted on an end of the connecting member 2 away from the support rod 202 , and the first handle 1 is a telescopic structure.

[0048] Specifically, in this example, there are two support rods 202, and the insertion rod 3 is detachably installed on the connecting member 2 between the two support rods 202. After the insertion rod 3 is installed on the connecting member 2, its end can be flush with the end of the support rod 202.

[0049] Specifically, the first concave cavity 201 is respectively arranged on the upper and lower surfaces of the connecting member 2, and the second concave cavity 301 is respectively arranged on the upper and lower surfaces of the insertion rod 3. This arrangement can form a cross-section of the connecting member 2 and the insertion rod 3 similar to an I-beam structure, which has stronger structural stability and can reduce material costs.

[0050] Specifically, both sides of the front end of the support rod 202 and the insertion rod 3 have branches 5 that are inclined outward, and the two branches 5 form a V-shaped structure. The loosening wheel 4 is mounted on the V-shaped structure and is limited by a cotter pin installed at the end of the branch 5. More specifically, a pin hole 6 perpendicular to the center line of the branch 5 is opened near the outer end of the branch 5, and the cotter pin can be inserted into the pin hole 6 to achieve the positioning of the loosening wheel 4.

[0051] Specifically, the loosening wheel 4 has teeth 401 extending outward and evenly distributed in the circumferential direction, and the ends of the teeth 401 form a spike portion 402. The teeth 401 on the two loosening wheels 4 at the front end of the same support rod 202 or the same insertion rod 3 are staggered. On the one hand, it can avoid mutual interference between the teeth 401, and on the other hand, it can improve the uniformity of loosening the soil.

[0052] Specifically, the insertion rod 3 and the first handle 1 are both detachably mounted on the connector 2 by means of a spring pin 8. As in the connection structure between the insertion rod 3 and the connector 2, small holes are provided on the insertion rod 3 and the connector 2 respectively, and the spring pin 8 can be inserted into the two small holes, thereby achieving docking between the insertion rod 3 and the connector 2. When disassembling, only the spring pin 8 needs to be pressed to complete the disassembly of the two. Similarly, the disassembly and assembly of the first handle 1 and the connector 2 also adopts the above principle.

[0053] Specifically, the connecting member 2 is made of metal or alloy, more specifically, cast aluminum in this example; the inserting rod 3 is made of nylon.

[0054] Specifically, the first handle 1 includes a plurality of short rods 101 that are sequentially sleeved and can be connected end to end. Among two adjacent sleeved short rods 101, the ends of the outer short rods 101 are installed with plastic sleeves 102, wherein, Figure 6 As shown, two adjacent short rods 101 are sleeved on each other, and can be connected at the end connection position by using threads or friction in the prior art. In order to prevent the end of the short rod 101 at the external position from being stretched, a plastic sleeve 102 is provided at its end to strengthen the structural strength of the end of the short rod 101.

[0055] Specifically, it also includes a second handle 7, which is detachably connected to the insertion rod 3 and is used to loosen the soil by operating the second handle 7 alone.

[0056] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
