Description

STATE OF THE ART

[0001] The present invention relates to the technical field of hand-held power tools, more particularly to a hand-held device for improving the ease of use when drilling and shoveling. TECHNICAL BACKGROUND

[0002] In typical home and garden applications, there is often a need to dig small holes or trenches in the ground. For example, garden shovels are commonly used for tasks such as planting plants, planting bulbs, laying outdoor lighting cables, outdoor sound cables, fence posts, irrigation hoses, etc. However, using handheld garden shovels for such ground hole and cavity excavation tasks can be difficult and strenuous. CONTENTS OF THE INVENTION

[0003] The aim of the present invention is, in view of the shortcomings of the existing state of the art, to provide a hand-held drilling and shoveling device that improves the user-friendliness of hole or cavity excavation work.

[0004] The technical measures of the present invention are as follows:

[0005] This invention is based on the existing problem that difficulties and high expenditure of force can occur when using existing hand-held garden shovels for soil hole and cavity excavation work.

[0006] Based on this, the present invention provides a hand-held drilling and shoveling device that can improve the operator-friendliness of bottom hole or cavity excavation work. It comprises:

[0007] A handle and a drill head and a scoop plate attached to one end of this handle, the scoop plate being arranged laterally next to the drill head to form a receiving structure for drilling material;

[0008] The handle is connected to a drive motor which has a drive shaft to output torque;

[0009] The drive shaft is connected to the drill head to drive it for turning.

[0010] During operation, the cutter head can perform a rotary operation to drill holes, while the stationary bucket plate is typically positioned below the cutter head to collect the cuttings generated by the cutter head (such as soil created during drilling). This prevents the cuttings from falling back into the hole dug by the cutter head, allows for their collection and removal, and thus improves the operator experience of bottom hole or cavity excavation operations.

[0011] Furthermore, the handheld drilling and digging tool combines the functions of drilling and digging. It typically includes a drive motor for providing rotational power and a drill head that receives the rotational power to perform a rotary digging motion. Based on the requirements of handheld tools for digging work, a frictional connection between the drive motor and the drill head shaft of the drill head via a reduction gear is required to achieve speed reduction and torque increase, allowing the drill head to dig holes stably and powerfully in a low-speed, high-torque state.

[0012] For hand-held excavators, not all reduction gear structures can be equally well selected and adapted. For example, in a conventional reduction gear structure, in which a pinion gear is fixedly mounted on the drive motor drive shaft, a large gear is fixedly mounted on the cutter head shaft, and the pinion gear meshes with the large gear to achieve speed-reducing power transmission, this results in the hand-held device requiring a larger space to accommodate the two staggered gears. This forces a larger housing structure, which does not well meet the needs for compactness and portability of hand-held devices. On the other hand, the cutter head shaft and drive shaft must also be staggered, further increasing the requirement for a large housing.

[0013] Based on this, the present invention further provides a handheld drilling and shoveling device that can better meet the usage requirements of handheld tools. It comprises:

[0014] A handle and a drill head and a scoop plate attached to one end of this handle, the scoop plate being arranged laterally next to the drill head to form a receiving structure for drilling material;

[0015] The handle is connected to a drive motor which has a drive shaft for outputting a rotational force;

[0016] The drill head comprises: a drill head shaft rotatably connected to the handle and a cutting edge extending spirally along the outer periphery of this drill head shaft;

[0017] The drive shaft is non-positively connected to the drill head shaft via a planetary gear group, whereby this planetary gear group is a planetary gear structure that transmits the rotation of the drive shaft to the drill head shaft in a speed-reducing manner.

[0018] This means that in the above design, taking into account the use of the handheld device, a planetary gear structure is used as the speed-reducing power transmission structure between the drill bit shaft and the drive shaft. This not only stably transmits the rotational force of the drive shaft to the drill bit shaft in a speed-reducing and torque-increasing manner, driving the drill bit to rotate at low speed and high torque, but also has a smaller footprint, enabling a more compact arrangement to reduce the volume of the handheld drilling and digging device, thus meeting its portability requirements.

[0019] Of course, the planetary gear group with planetary gear structure in the above design can have various structures. Taking into account the requirements of transmission stability, so that the drill head can also be used in the conventional inclined loading state (combined with the arrangement of the blade plate, often as in Fig. 2 shown in the hole excavation work). In some versions, the planetary gear group includes a single-stage reduction structure. This single-stage reduction structure includes:

[0020] In some designs, the planetary gear group includes a single-stage reduction structure. This single-stage reduction structure includes;

[0021] A first drive wheel fixedly connected to the drive shaft and rotating coaxially therewith;

[0022] A first driven gear rotatably connected to the handle and coaxially rotating with the first drive gear, said first driven gear being connected to the drill head shaft to drive the drill head shaft to rotate;

[0023] First planetary gears rotatably connected to the first output gear, which are configured in a plurality of ways to surround the first drive gear in a distributed and spaced manner, each first planetary gear being meshingly connected to the first drive gear;

[0024] A first position locking ring, fixedly connected to the handle, encloses the first drive gear, wherein a plurality of first planetary gears are arranged within this first position locking ring, and each first planetary gear is meshed with the inner wall of the first position locking ring. Thus, the fixed first position locking ring forms a support for the rotation of the first planetary gears and achieves a guide limit. This not only ensures stable rotation of the first planetary gears, but also increases the transmission stability of the overall structure of the planetary gear group and its assembly stability. When the hand-held drilling and shoveling device digs at different angles, the load can be absorbed better and more stably.

[0025] On the above basis, to further increase the stability of the power transmission structure and to better adapt to digging movements with different force application angles.

[0026] In some designs, several first planetary gears are evenly distributed around the outer periphery of the first drive gear. This ensures a uniform power distribution around the outer periphery of the first drive gear. During digging movements of the hand-held drilling and shoveling device at different angles, the first drive gear can always stably transmit the rotational force via the first planetary gears to the first output gear and the drill head shaft.

[0027] Of course, taking into account the gear ratio limitation of the single-stage reducer structure, in order to have a wider gear ratio control range.

[0028] In some embodiments, the planetary gear group further comprises: a two-stage reduction structure arranged between the first output gear and the drill head shaft;

[0029] The first output gear is connected to the drill head shaft via this two-stage reduction structure, transmitting the rotation of the first output gear to the drill head shaft in a speed-reducing manner. This creates a multi-stage superimposed planetary reduction structure that expands the gear ratio control range and can adapt to different operating requirements.

[0030] The two-stage reducer structure of the present invention can also have various structures. However, in view of the excellent transmission stability and load stability of the above single-stage reducer structure, it is preferable that the two-stage reducer structure in the present invention be constructed accordingly.

[0031] That is, in some designs, the two-stage reduction structure includes:

[0032] A second drive wheel arranged on the opposite wall side of the drive shaft on the first output wheel and rotatable coaxially therewith;

[0033] A second drive gear arranged on a side wall of the first driven gear facing away from the drive shaft and rotating coaxially with this first driven gear;

[0034] A second output gear rotatably connected to the handle and coaxially rotating with the first drive gear, said second output gear being connected to the drill head shaft to drive it to rotate;

[0035] Second planetary gears, rotatably connected to the second output gear, which are plural in number to surround the second drive gear in a distributed and spaced manner, wherein each second planetary gear is meshingly connected to the second drive gear;A second position locking ring, fixedly connected to the handle and enclosing the second drive gear, wherein a plurality of second planetary gears are arranged within this second position locking ring and each second planetary gear is meshingly connected to the inner wall of the second position locking ring.

[0036] To further increase the stability of the power transmission structure and to better adapt to digging movements with different force application angles.

[0037] In some designs, several second planetary gears are evenly distributed around the outer periphery of the first drive gear.

[0038] In the designs using a planetary gear group described above, especially in designs using multi-stage reduction structures, there is a problem that the first drive gear, as a transmission structure directly driven by the drive shaft, is subjected to a high load and is therefore easily prone to skew or unstable rotation.

[0039] Therefore, in some designs, the following are rotatably connected to the first drive wheel: support planetary gears located between the first drive wheel and the drive motor;

[0040] The support planetary gears are designed in multiple configurations and surround the drive shaft in a distributed and spaced manner;

[0041] The handle is firmly connected to: A support position locking ring that encloses the drive shaft;

[0042] Several support planetary gears are arranged within this support position locking ring, and each support planetary gear meshes with the inner wall of the support position locking ring. This further increases the transmission stability of the first drive gear and improves its load capacity. During excavation movements with different force application angles, the first drive gear can always better and more stably transmit the rotational force of the drive shaft to the planetary gear group, which then transmits it to the drill head to drive it for stable hole drilling.

[0043] For handheld drilling and shoveling equipment to meet the usage requirements of handheld tools in more dimensions.

[0044] In some designs, the protrusion of the auger head beyond one end of the handle is greater than the protrusion of the shovel plate beyond one end of the handle. This allows the auger head to contact the excavated material more quickly than the shovel plate, and the shovel plate impedes the digging of the auger head less. Therefore, there is no need to force the shovel plate between the auger head and the excavated material to start the digging movement, which reduces the effort required for the digging movement.

[0045] In some embodiments, the handle comprises: an object housing portion connected to the planetary gear group and a handle housing portion for force-applying gripping;

[0046] The drill head and handle housing section are respectively arranged at both ends of the object housing section, and the extension direction of the handle housing section is set at an angle to the extension direction of the drill head shaft to achieve: There is a force application angle A between the drill head shaft and the handle housing section. This allows the operator to more easily push the drill head shaft for drilling by gripping the handle housing section, which increases the ease of use and effort efficiency of the hand-held drilling and shoveling device.

[0047] In some designs, a cover plate is also provided at one end of the handle, which completely shields the drill head in the direction from the handle to the drill head. When the operator grasps the handle to push the drill head forward for excavation work, this cover plate forms a protective structure. The rapid rotation of the drill head better prevents drilling debris or other foreign matter from splashing toward the handle and damaging the operator's hands.

[0048] In some designs, a cover plate is also provided at one end of the handle, which completely shields the drill head in the direction from the handle to the drill head. When the operator grasps the handle to push the drill head forward for excavation work, this cover plate forms a protective structure. The rapid rotation of the drill head better prevents drilling debris or other foreign matter from splashing toward the handle and damaging the operator's hands.

[0049] The advantages of these technical designs are: 1. Formation of a hand-held excavator that combines a drill head and a shovel plate, which can improve the operability of bottom hole or cavity excavation work. 2. The use of a planetary gear drive system, based on reducing the speed and increasing the drill head torque to improve the stability of the hole excavation and increase the load-bearing capacity, combined with the characteristics of the planetary gear structure, can better realize a more compact layout, reduce the overall volume, and reduce the weight. This allows the hand-held drilling and digging rig to be made more compact and lighter, better meeting the user-friendliness requirements of hand-held equipment. 3. The planetary gear structure with a fixed gear race outside the planetary gears not only supports the rotation of the planetary gears but also restricts their rotation, ensuring stable rotation; it also increases the transmission stability of the overall structure of the planetary gear group and its assembly stability; and can better and more stably bear the load when the hand-held drilling and digging machine digs at various angles. 4. Uniform distribution of planetary gears and joint load distribution result in higher torque output capability per unit volume, enable greater torque in a compact volume, and better meet the load requirements for hole excavation of hand-held equipment. 5. Multi-stage reduction drive structures and power distribution through simultaneous engagement of multiple gears reduce single-tooth loads, increase transmission efficiency and stability, and enhance shock resistance. Even during oblique drilling movements, stable power transmission can be better ensured, better meeting the load requirements of handheld hole excavation equipment. 6. Due to the dimension limitations of the shovel plate and drill head on the combined hand-held drill and shovel rig, using this device for drilling holes may be more energy-efficient. 7. Based on the drilling scenario requirements of the hand-held drilling and shoveling rig, the handle is improved to increase the ease of use and effort efficiency during use. 8. Based on the drilling scenario requirements of the hand-held drilling and shoveling rig, a cover plate is provided to increase safety and protection during use. 9. A battery is provided to better expand the application scenario of the handheld device and improve the portability and ease of use of the hand-held drilling and shoveling device.

[0050] Further or more detailed advantageous effects are explained in the concrete embodiment in combination with concrete embodiment examples. DRAWING

[0052] The invention is explained in detail below using exemplary embodiments: Example:

[0053] A hand-held drilling and shoveling device, such as in Fig. 1 is a hand-held tool for drilling holes in the ground or other objects.

[0054] As in Fig. 1 to Fig. As shown in Figure 8, the hand-held drilling and shoveling device in this embodiment comprises: a handle 1 for gripping by the operator, as well as a drill head 2 and a shovel plate 3 attached to one end of this handle 1. The shovel plate 3 is arranged laterally next to the drill head 2 to form a receiving structure for drilling material.

[0055] The drill head 2 comprises: a drill head shaft 2.1 rotatably connected to the handle 1 and a cutting edge 2.2 which extends spirally along the outer periphery of this drill head shaft 2.1 to enable the drill head 2 to be rotated on the handle 1.

[0056] The blade plate 3 is a plate component that is removably connected to the handle 1, for example, via screws or snap connections. When the drill head 2 performs a drilling operation, the blade plate 3 is typically arranged below the drill head 2 and forms a receiving structure that prevents the cuttings generated during drilling by the drill head 2 from falling back into the drilled hole.

[0057] As in Fig. 3, the drill head 2 is arranged in a projecting manner at one end of the handle 1, the blade plate 3 is also arranged in a projecting manner at one end of the handle 1 and is located laterally next to this drill head 2; and the projecting length of the drill head 2 beyond one end of the handle 1 is greater than the projecting length of the blade plate 3 beyond one end of the handle 1.

[0058] At the same time, the handle 1 is connected to a drive motor 4, which provides the rotational force. This drive motor 4 has a drive shaft 4.1 for outputting the rotational force. The drive motor 4 receives electrical input power through electrical connection to a power source. The power source can be a socket structure, wherein the drive motor 4 is connected to the socket via a cable during use to realize the power supply; or, as shown in Fig. As shown in Figure 1, a battery 8 may also be installed and connected to the handle 1, which is electrically connected to the drive motor 4 to supply it with power. The battery 8 may be a rechargeable lithium battery or another rechargeable battery.

[0059] The drive shaft 4.1 is frictionally connected to the drill head shaft 2.1 via a planetary gear group 5. The planetary gear group 5 is a planetary gear structure that transmits the rotation of the drive shaft 4.1 to the drill head shaft 2.1, reducing its speed.

[0060] In this way, if as in Fig. 2, the drive motor 4 is switched on, the drill head shaft 2.1 rotates and transmits this rotation in a reduced manner to the drill head 2 via the planetary gear group 5. The drill head 2 rotates rapidly in order to be able to carry out a hole drilling operation upon penetrating the ground c. As the drill head 2 drills and generates drilling debris, this drilling debris falls onto the bucket plate 3 due to gravity and is collected by it, preventing it from falling back into the hole and forming unwanted fill material.

[0061] Furthermore, the handle 1 can comprise: an object housing section 1.1 connected to the planetary gear group 5, and a handle housing section 1.2 for force-applying gripping. The drill head 2 and the handle housing section 1.2 are each arranged at both ends of the object housing section 1.1, and the extension direction of the handle housing section 1.2 is set at an angle to the extension direction of the drill head shaft 2.1 to achieve: a force application angle A exists between the drill head shaft 2.1 and the handle housing section 1.2.

[0062] For example, as in Fig. 3, the axis (a) of the drill head shaft 2.1 is arranged horizontally, the handle housing section 1.2 is, for example, an inclined cylinder whose center line (b) is inclined to form an angle A with the axis of the drill head shaft 2.1. This formation of the angle A has the effect that, when gripping the handle housing section 1.2, the application of a thrust force to the handle 1 is facilitated, which drives the drill head shaft 2.1 along its axis to a drilling movement. The planetary gear group 5 can be a single-stage drive structure.

[0063] For example, as in Fig. 4 and Fig. As shown in Figure 5, the planetary gear group 5 comprises a single-stage reduction structure. This single-stage reduction structure includes: a first drive gear 5.1, a first output gear 5.2, first planetary gears 5.3, and a first position locking ring 5.4.

[0064] The first drive gear 5.1 is fixedly connected to the drive shaft 4.1, for example, via a screw structure, and rotates coaxially with this drive shaft 4.1. The first driven gear 5.2 is rotatably connected to the handle 1, and its rotational axis is arranged collinearly with the rotational axis of the first drive gear 5.1, so that the first driven gear 5.2 can rotate coaxially with this first drive gear 5.1 (coaxial rotation in the present invention means that the rotational axes of two rotating objects are arranged collinearly). And this first driven gear 5.2 is connected to the drill head shaft 2.1 to drive it to rotate. For example, the first driven gear 5.2 is directly connected to the drill head shaft 2.1 via a structure such as screws or a coupling, so that the rotation of the first driven gear 5.2 can rotate the drill head shaft 2.1 synchronously.

[0065] At the same time, the first output gear 5.2 has a side facing the first drive gear 5.1. A plurality of first planetary gear connecting pins 5.21 are arranged in a projecting manner on this side. A plurality of first planetary gear connecting pins 5.21 are distributed and spaced apart around the first drive gear 5.1, and a first planetary gear 5.3 is rotatably connected to each first planetary gear connecting pin 5.21. A plurality of first planetary gears 5.3 are distributed and spaced apart around the first drive gear 5.1, and each first planetary gear 5.3 is meshingly connected to the first drive gear 5.1.

[0066] The first position locking ring 5.4 is an annular collar, firmly connected to the handle 1, which encloses the first drive gear 5.1. Several first planetary gears 5.3 are arranged within this first position locking ring 5.4, and each first planetary gear 5.3 is meshingly connected to the inner wall of the first position locking ring 5.4.

[0067] Thus, when the drive shaft 4.1 rotates, it synchronously drives the first drive gear 5.1. The first drive gear 5.1 drives a plurality of first planetary gears 5.3 to rotate independently via a meshing power transmission. Under the action of the first position locking ring 5.4, a plurality of first planetary gears 5.3 synchronously rotate around the first drive gear 5.1, thereby driving the first driven gear 5.2 to rotate the drill head shaft 2.1 to perform the hole drilling operation.

[0068] The number of the first planetary gears 5.3 is determined according to the requirements. For example, as in Fig. 5, five first planetary gears 5.3 can be provided. Regardless of how many first planetary gears 5.3 are provided, several first planetary gears 5.3 are evenly distributed around the outer periphery of the first drive gear 5.1.

[0069] Furthermore, in this embodiment, the interior of the handle 1 is hollow. The drive motor 4 and the single-stage reduction structure (comprising: first drive gear 5.1, first output gear 5.2, first planetary gears 5.3, and first position locking ring 5.4) are preferably housed in the handle 1 to be enclosed and protected.

[0070] Or the planetary gear group 5 can also be a two-stage drive structure with a larger gear ratio.

[0071] For example, as in Fig. 6 and Fig. As shown in Figure 7, the planetary gear group 5 in this embodiment, based on the above single-stage reduction structure, further includes a two-stage reduction structure arranged between the first output gear 5.2 and the drill head shaft 2.1. The first output gear 5.2 is connected to the drill head shaft 2.1 via this two-stage reduction structure to transmit the rotation of the first output gear 5.2 to the drill head shaft 2.1 in a speed-reducing manner. The single-stage reduction structure and the two-stage reduction structure together constitute the planetary gear group 5 with a multi-stage planetary reduction structure.

[0072] Specifically, the two-stage reduction structure includes: a second drive gear 5.5, a second output gear 5.6, second planetary gears 5.7 and a second position locking ring 5.8.

[0073] The second drive wheel 5.5 is a gear structure which is arranged in a projecting manner on a side wall of the first driven wheel 5.2, which is facing away from the drive shaft 4.1, and rotates coaxially with this first driven wheel 5.2.

[0074] The second driven gear 5.6 is rotatably connected to the handle 1, and its rotational axis is arranged collinearly with the rotational axis of the second drive gear 5.5, so that the second driven gear 5.6 can rotate coaxially with this second drive gear 5.5 (coaxial rotation in the present invention means that the rotational axes of two rotating objects are arranged collinearly). And this second driven gear 5.6 is connected to the drill head shaft 2.1 to drive it to rotate. For example, the second driven gear 5.6 is directly connected to the drill head shaft 2.1 via a structure such as screws or a coupling, so that the rotation of the second driven gear 5.6 can rotate the drill head shaft 2.1 synchronously.

[0075] At the same time, the second output gear 5.6 has a side facing the second drive gear 5.5. A plurality of second planetary gear connecting pins 5.61 are arranged in a projecting manner on this side. A plurality of second planetary gear connecting pins 5.61 are distributed and spaced apart around the second drive gear 5.5, and a second planetary gear 5.7 is rotatably connected to each second planetary gear connecting pin 5.61. A plurality of second planetary gears 5.7 are distributed and spaced apart around the second drive gear 5.5, and each second planetary gear 5.7 is meshingly connected to the second drive gear 5.5.

[0076] The second position locking ring 5.8 is an annular collar, firmly connected to the handle 1, which encloses the second drive gear 5.5. Several second planetary gears 5.7 are arranged within this second position locking ring 5.8, and each second planetary gear 5.7 is meshingly connected to the inner wall of the second position locking ring 5.8.

[0077] Thus, as described above, when the drive shaft 4.1 rotates, thereby driving the first driven gear 5.2 to rotate, it synchronously drives the second drive gear 5.5 to rotate. The second drive gear 5.5 drives a plurality of second planetary gears 5.7 to rotate independently via meshing power transmission. Under the action of the second position locking ring 5.8, a plurality of second planetary gears 5.7 synchronously orbit around the second drive gear 5.5, thereby driving the second driven gear 5.6 to rotate the drill head shaft 2.1 to perform the hole drilling work.

[0078] The number of second planetary gears 5.7 is determined according to the requirements. For example, as in Fig. 5, five second planetary gears 5.7 may be provided. Regardless of how many second planetary gears 5.7 are provided, several second planetary gears 5.7 are evenly distributed around the outer periphery of the second drive gear 5.5.

[0079] Furthermore, in this embodiment, the interior of the handle 1 is hollow. While the drive motor 4 and the single-stage reduction structure are housed in the handle 1, the two-stage reduction structure (comprising the second drive gear 5.5, the second driven gear 5.6, the second planetary gears 5.7, and the second position locking ring 5.8) is also preferably housed in the handle 1 to be enclosed and protected.

[0080] Furthermore, regardless of whether the planetary gear group 5 is equipped with a single-stage or multi-stage reduction structure, as shown in Fig. 8, a flange section 5.11 is formed projecting on the outer edge of the first drive gear 5.1. This flange section 5.11 has a side wall facing away from the first planet gears 5.3. Several support planet gear connecting bolts 5.12 are arranged on this side wall and are distributed and spaced apart around the drive shaft 4.1. A support planet gear 6 is rotatably connected to each support planet gear connecting bolt 5.12. The support planet gears 6 are formed in multiples and surround the drive shaft 4.1 in a distributed and spaced apart manner.

[0081] At the same time, the handle 1 is also firmly connected to an annular support position locking ring 7, which surrounds the drive shaft 4.1. Several support planetary gears 6 are arranged within this support position locking ring 7, and each support planetary gear 6 is meshingly connected to the inner wall of the support position locking ring 7. The support position locking ring 7 is housed in the handle 1 together with the planetary gear group 5.

[0082] Furthermore, a cover plate 3.1 can be provided at one end of the handle 1, which completely shields the drill head 2 in the direction from the handle 1 to the drill head 2. This cover plate 3.1 can be a plate component independent of the blade plate 3, which is firmly connected to the handle 1, for example, via a snap-in connection structure. Or the cover plate 3.1 is formed integrally with the blade plate 3, so that the fixed connection of the blade plate 3 is realized by connecting the cover plate section 3.1 to the handle 1.

[0083] As in Fig. 1 to Fig. 3, the bucket plate 3 can be a plate structure made of metal or metal-like hard material in order to be able to penetrate directly into the ground for digging when picking up drilling material.

[0084] Or, for example, as in Fig.As shown in Figure 9, the blade plate 3 may also be a plate or sleeve component made of a soft material such as rubber or silicone. This can, as described above, block the soil and other cuttings produced by the drill head 2 during excavation, preventing them from falling back into the excavated hole or splashing around.

[0085] If the blade plate 3 is a plate or shell component made of soft material such as rubber or silicone, a plurality of cuttings retention grooves 3.2 may be formed on the side of the blade plate 3 facing the drill head 2 in order to prevent the cuttings from slipping off.
