Description

Technical Field

[0001] This utility model relates to the field of drilling device technology, and in particular to a hammer-type clay layer drilling device. Background Technology

[0002] Insect traps are widely used for pest control in crops due to their environmental friendliness, high efficiency, and precise targeting. Insect traps generally require a support pole; one end of the pole is inserted into the soil for fixation, and then the insect trap is suspended from the pole. To ensure the effectiveness of the insect trap and prevent it from being blown over by strong winds, the pole needs to penetrate the soft soil layer and be inserted into the hard soil layer for fixation. Because the hard soil layer has a compact structure, and the pole is also quite tall, it is difficult to manually press the pole into the hard soil layer. Generally, a hole needs to be drilled first, and then the pole inserted into the soil.

[0003] Existing manual soil aerators mainly consist of a handle, a punching rod, a punching head, and a foot pedal, as detailed in the patent "Single-Head Foot-Pedal Soil Aerator for Planting" (CN 104956794 A). In use, the handle is held and the foot pedal is pressed to insert the punching head and part of the punching rod into the soil. This tool is simple in structure and easy to operate, but it is more suitable for drilling holes in topsoil. For clay soils, it is difficult to drill holes by foot, and when drilling in clay soils, pressing only one side of the foot pedal easily leads to misalignment; using the hand to straighten the hole results in more force. Using a hammer or other tools to drive the punching head into hard soil layers is difficult, and pulling out the aerator is also strenuous, making it inconvenient for daily drilling operations. Utility Model Content

[0004] To address the above shortcomings, this utility model provides a hammer-type clay layer drilling tool to solve the problems of existing drilling tools being difficult to penetrate hard soil layers and requiring great effort to pull out the drilling tool.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a sleeve hammer clay layer drilling tool, comprising a handle, a drilling rod, and a drilling head. One end of the drilling rod is provided with the drilling head, and the other end with the handle. It also includes an upper retaining ring, a lower retaining ring, and a sleeve hammer. The upper retaining ring is located on the outer periphery of the drilling rod below the handle, and the lower retaining ring is located in the lower middle part of the drilling rod. The sleeve hammer is sleeved on the drilling rod between the upper and lower retaining rings. The overall height of the sleeve hammer is less than the height difference between the upper and lower retaining rings. The sleeve hammer can slide up and down along the drilling rod and strike the upper or lower retaining ring. In use, the sleeve hammer strikes the lower retaining ring downwards to insert the drilling rod into the soil, and the sleeve hammer strikes the upper retaining ring upwards to remove the drilling rod from the soil layer. The operation is convenient, simple, and labor-saving.

[0006] Preferably, a frustum-shaped compaction section is provided below the lower retaining ring, and the compaction section is located on the outer periphery of the drilling rod. The compaction section compacts the soil around the hole opening, making it less likely for soil to flow back when the drilling rod is pulled out, which is beneficial for inserting the upright rod into the hole.

[0007] Preferably, the compaction part is fixed to the bottom of the lower retaining ring by a spring or rubber pad, and can slide up and down relative to the punching rod.

[0008] Preferably, a foot pedal is provided on the outer side of the lower retaining ring. The drilling rod can be inserted into the tillage layer by stepping on the foot pedal.

[0009] Preferably, there are two foot pedals, which are symmetrically arranged on both sides of the lower retaining ring, resulting in a more balanced structure.

[0010] Preferably, the upper and lower ends of the hammer are respectively provided with an upper impact ring and a lower impact ring. Both the upper and lower impact rings are annular, and their inner diameters are smaller than the inner diameter of the hammer, while their outer diameters are larger than the outer diameter of the hammer. This facilitates operation and prevents the hammer from deforming.

[0011] Preferably, the hammer, upper impact ring, and lower impact ring are all made of metal, and the weight of the lower impact ring is greater than the weight of the upper impact ring.

[0012] Preferably, the handle is coaxially arranged with the punch rod, and the diameter of the handle is larger than the diameter of the punch rod but smaller than the diameter of the upper retaining ring. Preferably, a rubber sleeve is also provided on the handle.

[0013] Preferably, the distance from the lower retaining ring to the end of the punch head is 30-40cm. Preferably, the distance from the handle to the end of the punch head is 90-120cm, which facilitates handheld operation.

[0014] Preferably, the diameter of the punching rod is 1-3 cm. That is, the diameter of the matching column is 1-3 cm, which can not only fix the insect trap well, but also reduce the resistance of the punching operation.

[0015] Compared with the prior art, the beneficial effects of this utility model include: 1. This utility model features an upper retaining ring, a lower retaining ring, and a hammer on a punching rod. The hammer can slide up and down along the punching rod and strike the upper or lower retaining ring. In field use, the punching rod is first pressed into the topsoil layer, and then the hammer strikes the lower retaining ring to insert the punching rod into the clay layer. The hammer strikes downwards along the punching rod, which, compared to using a separate hammer, is more conducive to the vertical force on the punching head, allowing the punching rod to be inserted vertically into the soil. Furthermore, after punching, the punch can be easily removed by reversing the hammer's operation, i.e., striking the upper retaining ring with the hammer. The operation is convenient, simple, and labor-saving, and it is also easy to carry.

[0016] 2. This utility model features a frustum-shaped compaction section below the lower retaining ring. As drilling is completed, this compaction section compacts the soil around the hole, preventing soil backflow when the drilling rod is pulled out, thus facilitating the insertion of the upright into the hole. Simultaneously, checking the compaction of the soil in the hole allows for verification that the drilling operation was performed according to specifications and to the prescribed depth, ensuring the stability of the upright. The compaction section can be fixed to the lower retaining ring and the drilling rod, or it can be fixed to the bottom of the lower retaining ring via a spring or rubber pad, and can slide up and down relative to the drilling rod, providing both cushioning and enhanced compaction of the surrounding soil.

[0017] 3. This utility model strengthens the overall structure of the hammer by providing an upper impact ring and a lower impact ring at the upper and lower ends of the hammer, respectively. The inner diameter of both the upper and lower impact rings is smaller than the inner diameter of the hammer, while their outer diameters are larger than the outer diameter of the hammer. This prevents deformation during impact due to the thinness of the hammer's ends, thus extending the lifespan of the drill. Simultaneously, the thicker lower retaining ring increases the weight of the hammer, which is beneficial for drilling operations. Attached Figure Description

[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0023] Example 1 like Figure 1 As shown, a clay layer drilling tool with a sleeve hammer 7 includes a handle 1, a drilling rod 2, a drilling head 3, a foot pedal 4, an upper retaining ring 5, a lower retaining ring 6, and a sleeve hammer 7. The handle 1, drilling rod 2, drilling head 3, foot pedal 4, upper retaining ring 5, lower retaining ring 6, and sleeve hammer 7 of this application are all made of metal. By adding structures such as the upper retaining ring 5, lower retaining ring 6, and sleeve hammer 7, this application can solve the problems of existing drilling tools having difficulty penetrating hard soil layers and the difficulty in pulling out the drilling tool.

[0024] Combination Figure 2 The handle 1 is located at the top of the punching rod 2 and is vertically aligned coaxially with the punching rod 2. The diameter of the handle 1 is larger than the diameter of the punching rod 2 but smaller than the diameter of the upper retaining ring 5, facilitating gripping and operation. In this embodiment, a non-slip rubber glove is fitted over the top of the punching rod 2 to serve as the handle 1. In other embodiments, the handle 1 can also be made by welding a collar or other methods.

[0025] The drilling rod 2 is used to install the handle 1, drilling head 3, foot pedal 4, upper retaining ring 5, lower retaining ring 6, and hammer 7, and is inserted into the soil to drill holes under the action of external force such as the hammer 7. In this embodiment, the height of the drilling rod 2 is about 110cm, which is convenient for hand operation. The diameter of the drilling rod 2 is 1.5cm, that is, the diameter of the matching column is about 1.5cm, which can not only fix the insect trap well, but also reduce the resistance of the drilling operation.

[0026] The punch head 3 is fixed to the bottom of the punch rod 2 and is inverted conical in shape. In this example, the punch head 3 and the punch rod 2 are integrally formed and do not require other connecting structures for fixation. That is, the connection between the punch head 3 and the punch rod 2 is smooth, which helps to reduce drilling resistance.

[0027] The upper retaining ring 5 is located on the outer periphery of the drilling rod 2 below the handle 1. The upper retaining ring 5 is annular and is fixed to the drilling rod 2 by welding. The diameter of the upper retaining ring 5 is larger than the diameter of the hammer 7. When the hammer 7 strikes the upper retaining ring 5 upwards, the upper retaining ring 5 will transfer the force to the drilling rod 2, making it easier to remove the drilling rod 2 from the soil. In some embodiments, wear-resistant sleeves can also be fitted onto the upper retaining ring 5 and the lower retaining ring 6 to further protect the upper retaining ring 5 and the lower retaining ring 6 and reduce noise.

[0028] The lower retaining ring 6 is located in the lower part of the drilling rod 2. The lower retaining ring 6 is also annular and is fixed to the drilling rod 2 by welding. The diameter of the lower retaining ring 6 is larger than the diameter of the hammer 7. When the hammer 7 strikes the lower retaining ring 6 downwards, the lower retaining ring 6 transfers the force to the drilling rod 2, facilitating the insertion of the drilling rod 2 into the clay layer. In this example, the distance from the lower retaining ring 6 to the end of the drilling head 3 is 35cm. Setting the lower retaining ring 6 lower facilitates the insertion of the drilling rod 2 into the clay layer, while maintaining a distance of more than 30cm between the lower retaining ring 6 and the end of the drilling head 3 allows the drilling rod 2 to penetrate the cultivated layer and penetrate a certain depth into the clay layer, making the pole more securely fixed.

[0029] The hammer 7 is sleeved on the drilling rod 2 between the upper retaining ring 5 and the lower retaining ring 6, combined with Figure 3 The hammer 7 is a ring-shaped structure with a certain height. The inner diameter of the hammer 7 is slightly larger than the diameter of the drilling rod 2. The overall height of the hammer 7 is less than the height difference between the upper retaining ring 5 and the lower retaining ring 6. That is, the hammer 7 can slide up and down along the drilling rod 2 and impact the upper retaining ring 5 or the lower retaining ring 6. In use, the hammer 7 impacts the lower retaining ring 6 downwards to insert the drilling rod 2 into the soil, and the hammer 7 impacts the upper retaining ring 5 upwards to remove the drilling rod 2 from the soil layer. The operation is convenient, simple, and labor-saving. Preferably, the upper and lower ends of the hammer 7 are respectively provided with an upper impact ring 9 and a lower impact ring 10. Both the upper and lower impact rings 9 and 10 are ring-shaped, and their inner diameters are smaller than the inner diameter of the hammer 7, while their outer diameters are larger than the outer diameter of the hammer 7. This is more conducive to the impact operation, and the hammer 7 is less likely to deform during the impact process, which helps to extend the service life of the hammer 7. Furthermore, the lower impact ring 10 is heavier than the upper impact ring 9, so the lower retaining ring 6 is lengthened and extends to the lower outer side of the hammer 7. Making the lower retaining ring 6 thicker increases the weight of the hammer 7, which is beneficial for the drilling operation.

[0030] Combination Figure 4 The foot pedal is located outside the lower retaining ring 6 and is perpendicular to the drilling rod 2. In this embodiment, there are two foot pedals 4, which are symmetrically arranged on both sides of the lower retaining ring 6 to facilitate force balance. The foot pedal 4 is a long strip, and one end of the foot pedal 4 is fixed to the drilling rod 2 by welding. In use, the drilling rod 2 can be pressed into the topsoil layer by stepping on the foot pedal 4.

[0031] Further integration Figure 4 Below the lower retaining ring 6, there is an inverted frustum-shaped compaction part 8, which is located on the outer periphery of the drilling rod 2. The compaction part 8 is fixed to the lower retaining ring 6 and the drilling rod 2 by welding. Simultaneously with drilling, the compaction part 8 compacts the soil around the hole, preventing soil backflow when the drilling rod 2 is pulled out, thus facilitating the insertion of the upright into the hole. Furthermore, checking the compaction of the hole can also be used to check whether the drilling operation is performed according to specifications and whether the hole is drilled to the prescribed depth, ensuring the stability of the upright.

[0032] In other embodiments, the compaction part 8 can also be fixed to the bottom of the lower retaining ring 6 by a spring or rubber pad, and can slide up and down relative to the perforating rod 2, which can both buffer and enhance the compaction of the air soil.

[0033] Use this hole punch to drill holes in the clay layer in the field and insert the post for hanging insect traps. The specific operation is as follows: First, hold the handle 1 or step on the foot pedal 4 to press the punch rod 2 into the cultivated soil layer. Then, use the hammer 7 to strike the lower retaining ring 6 to push the punch rod 2 into the clay layer. Repeat the impact several times to push the punch rod 2 to the desired depth. At the same time, the compaction part 8 will compact the soil around the hole. Next, reverse the operation of the hammer 7, that is, repeatedly strike the upper retaining ring 5 with the hammer 7 to easily remove the hole punch. The operation is convenient, simple, and labor-saving, and it is also easy to carry. Finally, insert the post into the drilled hole and compact it to secure it.

[0034] In summary, this hole puncher features an upper retaining ring 5 and a lower retaining ring 6 on the upper and lower parts of the punching rod 2, respectively. A movable sleeve hammer 7 is fitted onto the punching rod 2 between the upper and lower retaining rings 5 ​​and 6. The sleeve hammer 7 strikes the lower retaining ring 6 downwards to insert the punching rod 2 into the soil, and strikes the upper retaining ring 5 upwards to remove the punching rod 2 from the soil. This design is convenient, simple, and labor-saving. Furthermore, by providing a frustum-shaped compaction section 8 below the lower retaining ring 6, the compaction section 8 compacts the soil around the hole opening as drilling is completed. This prevents soil backflow when the punching rod 2 is pulled out, facilitating the insertion of the upright rod into the hole and making it easier to check the accuracy of the drilling operation. This invention is particularly suitable for drilling small-diameter holes in clay layers in the field.

[0035] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
