Implementation

[0023] Embodiments of the present utility model are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present utility model, and should not be construed as limitations on the present utility model. In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "upper surface", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the present utility model.

[0024] See also Figure 1-6 The utility model provides an embodiment: a yam digging tool, comprising a knife body part 1, a connecting piece 2 installed on the knife body part 1; the upper end of the connecting piece 2 is connected to a handle 4, and a guide rod 9 is also provided inside the handle 4; a percussion hammer 8 is slidably installed on the guide rod 9, and the percussion hammer 8 is adsorbed by an electromagnetic suction cup 6 provided at the upper end of the handle 4, so that the percussion hammer 8 slides upward along the guide rod 9; when the electromagnetic suction cup 6 is powered off, the percussion hammer 8 slides downward along the guide rod 9 to hit the knife body part 1, so that the knife body part 1 penetrates into the soil to dig out the yam.

[0025] In the above manner, the electromagnetic chuck 6 is powered on or off by connecting the wire to the external battery, and when powered on, the electromagnetic chuck 6 absorbs the hammer 8 to keep the hammer 8 away from the connecting piece 2; after power is off, the hammer 8 slides downward along the guide rod 9 under the action of gravity and hits the connecting piece 2, and the power is turned on and off synchronously and uninterruptedly, so that the cutter body 1 can be pushed deep into the soil, thereby improving the excavation efficiency of the device.

[0026] At the same time, the device is in the shape of a long strip as a whole, so it is easy for users to carry. When using it, you only need to cover the knife body part 1 on the outside of the yam, and then use the percussion hammer 8 to hit the knife body part 1, so that the knife body part 1 can be easily and conveniently pushed into the soil. In particular, the percussion hammer 8 can be used to knock the device so that it can also dig harder soil.

[0027] In order to further improve the excavation efficiency of the device, a spring 7 is further provided inside the handle 4, and the spring 7 is used to increase the force of the percussion hammer 8 hitting the blade part 1. Therefore, when the percussion hammer 8 moves upward, the spring 7 is compressed. After the electromagnetic chuck 6 is powered off, the spring 7 provides a faster initial velocity for the percussion hammer 8, so as to further increase the speed of the blade part 1 entering the soil. Based on this, the excavation efficiency of the device can be further improved.

[0028] At the same time, since a partition 10 is provided at the upper end of the handle 4, and the partition 10 is used to isolate the direct contact between the spring 7 and the electromagnetic suction cup 6, it is possible to avoid wear of the electromagnetic suction cup 6 during the up and down movement of the spring 7. At the same time, the partition 10 can also be used to simultaneously bear the pressure of the spring 7 and the attraction of the electromagnetic suction cup 6 to the hammer 8, thereby reducing the above-mentioned force acting on the electromagnetic suction cup 6, thereby reducing the problem of damage to the electromagnetic suction cup 6.

[0029] Furthermore, since the partition layer 10 is provided with a magnetically permeable hole, it is convenient for magnetic force to penetrate, thereby facilitating the electromagnetic suction cup 6 to attract the striking hammer 8 to move upward.

[0030] In addition, since the upper end of the handle 4 is connected to the outer cover 5, and the electromagnetic suction cup 6 is fixed to the handle 4 through the outer cover 5, the installation and replacement of the electromagnetic suction cup 6 are simple and convenient, and the outer cover 5 can also be used to prevent the electromagnetic suction cup 6 from being physically damaged by the outside.

[0031] On the basis of the above solution, since the side of the connecting member 2 is movably connected to the pedal 3, it is convenient for the user to step on the pedal 3 to further speed up the excavation efficiency of the equipment.

[0032] In order to facilitate the installation and replacement of the pedal 3, the connecting member 2 includes a main body 20, and the main body 20 is connected to the pedal 3 through a first connecting portion 21. Specifically, the pedal 3 is connected to the internal thread of the inner wall surface of the first connecting portion 21 through the external thread column provided thereon, so as to realize the installation and replacement of the pedal 3. In addition, since the pedal 3 is easy to install and replace, it is also convenient for the user to choose to use the pedal 3 or not to use the pedal 3 according to needs.

[0033] Furthermore, since the second connection part 23 having the same structure as the first connection part 21 is also provided on the side of the main body part 20 away from the first connection part 21, the installation position of the pedal 3 can be adjusted. In particular, when the pedal 3 is installed on the first connection part 21 and the second connection part 23 at the same time, the user steps on the pedal 3 with both feet and holds the handle 4 with both hands; at this time, with the striking of the hammer 8, the speed at which the device penetrates into the soil is further accelerated. In addition, since the hammer 8 can slide inside the handle 4, when the blade part 1 is pulled out of the soil, the impact of the hammer 8 facilitates the rapid discharge of the soil inside the blade part 1.

[0034] In order to facilitate the disassembly of the device, one end of the main body 20 is connected to the handle 4 through the third connection part 24, and the other end of the main body 20 is connected to the blade body 1 through the fourth connection part 25. Further, a fifth connection part 22 is also provided at the center of the main body 20, and the fifth connection part 22 is connected to the guide rod 9. Through the above-mentioned manner, that is, the arrangement of the first connection part 21, the second connection part 23, the third connection part 24, the fourth connection part 25 and the fifth connection part 22, each component installed on the connecting member 2 can be disassembled to reduce the volume of the device during transportation, wherein the inner wall surfaces of the first connection part 21, the second connection part 23, the third connection part 24, the fourth connection part 25 and the fifth connection part 22 are all provided with internal threads, which are connected with the external threads on each part through the internal threads, so that the assembly and disassembly of the device are facilitated, and the assembly of components is achieved by thread matching, which can also reduce the production cost of the device.

[0035] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions and variations of these embodiments are made without departing from the principles and spirit of the present invention, and still fall within the scope of protection of the present invention.
