[0022] See also Figures 1 to 9 The embodiment of the present application discloses a bamboo shoot digging device, including a rotating drive component 1, a soil-digging component 2 and a bamboo shoot cutting component 3; the rotating drive component 1 is used for rotating power output, a first connecting part 4 is provided on the rotating drive component 1, a second connecting part for detachably connecting with the first connecting part 4 is provided on the soil-digging component 2, and a third connecting part for detachably connecting with the first connecting part 4 is provided on the bamboo shoot cutting component 3; the soil-digging component 2 includes a soil-digging sleeve 21, a lower end of the soil-digging sleeve 21 is provided with an opening 22 for bamboo shoots to enter the interior of the soil-digging sleeve 21, an outer side wall of the soil-digging sleeve 21 is provided with a spiral blade 23 for breaking the soil, and an upper end of the soil-digging sleeve 21 is provided with a second connecting part; the bamboo shoot cutting component 3 includes a bamboo shoot cutting sleeve 31, a lower end of the bamboo shoot cutting sleeve 31 is provided with an opening 32 for bamboo shoots to enter the interior of the bamboo shoot cutting sleeve 31, a cutting structure 33 for cutting bamboo shoots is provided at the opening 32, and a third connecting part is provided at the upper end of the bamboo shoot cutting sleeve 31.

[0023] As can be seen from the above, by designing the combination of the rotating driving component 1, the soil-digging component 2 and the bamboo shoot cutting component 3, an efficient and convenient bamboo shoot digging process is achieved.

The three can be quickly assembled and disassembled by disassembling the connecting components, thereby solving the problems of low efficiency and high labor intensity of manual bamboo shoot digging in the prior art.

[0024] In this embodiment, the rotary drive component 1 includes a cylinder 11, a motor 12 and a rotary drive shaft 13. The cylinder 11 is provided with a mounting groove 111. The rotary drive shaft 13 is rotatably connected in the mounting groove 111. The motor 12 is fixedly installed in the mounting groove 111 and is used to drive the rotary drive shaft 13 to rotate. One end of the rotary drive shaft 13 extending out of the mounting groove 111 is connected to a first connecting portion 4. The rotary drive component 1, as the core driving part of the bamboo shoot digging device, includes the cylinder 11, the motor 12 and the rotary drive shaft 13. The cylinder 11 provides overall structural support and protection. The motor 12 is fixedly installed in the mounting groove 111 of the cylinder 11 as a power source, and the rotary power of the motor 12 is transmitted through the rotary drive shaft 13. One end of the rotary drive shaft 13 extends out of the mounting groove 111 and is connected to the first connecting portion 4, so that it can be easily disassembled and connected with the soil-digging component 2 and the bamboo shoot cutting component 3.

The combination of the motor 12 and the rotating drive shaft 13 ensures the stability and reliability of the device during operation through the fixed connection of the mounting groove 111. The design of the first connecting portion 4 makes it simple and quick to replace different working parts, further improving the practicality and flexibility of the device.

[0025] Continue to see Figure 3 and Figure 5In this embodiment, the motor 12 is connected to the rotating drive shaft 13 through a transmission assembly 14. Specifically, the transmission assembly 14 includes a driving gear 141 and a driven gear 142, wherein the driving gear 141 is fixedly connected to the output shaft of the motor 12, and the driven gear 142 is fixedly connected to the rotating drive shaft 13 and meshes with the driving gear 141. The transmission assembly 14 is designed to achieve power transmission between the motor 12 and the rotating drive shaft 13. By fixing the driving gear 141 to the output shaft of the motor 12 and fixing the driven gear 142 to the rotating drive shaft 13, the rotational motion of the motor 12 can be transmitted to the rotating drive shaft 13 through gear meshing, thereby driving the rotating drive shaft 13 to rotate. This design can ensure efficient power transmission, and through the meshing of gears, a relatively stable transmission effect can be achieved. The number of teeth of the driving gear 141 and the driven gear 142 can be designed and adjusted according to actual needs to achieve different transmission ratios, thereby meeting different work requirements. For example, the driving gear 141 and the driven gear 142 can adopt standard spur gears or helical gears to improve transmission efficiency and reduce noise. In addition, the material of the gear can be selected from high-strength alloy steel or other wear-resistant materials to improve the service life and reliability of the gear.

[0026] Continue to see Figure 3 and Figure 4 In this embodiment, the first connection part 4 includes a sleeve 41, a block 42 and a limiting structure 43. The sleeve 41 is fixedly connected to the lower end of the rotating drive shaft 13. There are two blocks 42. The two blocks 42 are radially slidably connected in the sleeve 41. One end of the block 42 extends out of the sleeve 41. The limiting structure 43 is used to limit the position of the block 42 in the sleeve 41. The second connection part and the third connection part each include two slots 5 for matching the block 42. The two slots 5 are radially spaced. The block 42 is radially slidably connected in the sleeve 41, so that the block 42 can move flexibly in the sleeve 41. The existence of the limiting structure 43 effectively controls the position of the block 42 in the sleeve 41, ensuring the reliability of the connection. The slot 5 design of the second connection part and the third connection part enables the soil-cutting part 2 and the bamboo shoot cutting part 3 to be quickly and firmly connected and disassembled with the first connection part 4, thereby improving the operating efficiency of the device. The design of the clamping block 42 needs to take into account the matching accuracy between the clamping block 42 and the sliding sleeve 41 to ensure that the clamping block 42 will not get stuck during the sliding process.

[0027] In this embodiment, the limiting structure 43 includes a limiting button switch 431, a pressure rod 432, a push rod 433 and a spring 434. A vertical hole 131 connected to the sliding sleeve 41 is provided in the rotating drive shaft 13. The pressure rod 432 is slidably arranged in the vertical hole 131. One end of the push rod 433 is hinged with the pressure rod 432, and the other end of the push rod 433 is hinged with the block 42. The upper end of the spring 434 is connected with the pressure rod 432, and the lower end of the spring 434 is connected with the bottom of the sliding sleeve 41. The limiting button switch 431 is installed on the cylinder 11, and the output end of the limiting button switch 431 is connected with the pressure rod 432. The effective control of the position of the block 42 is achieved through the limiting structure 43. The limiting button switch 431 can accurately control the position of the block 42 in the sliding sleeve 41 through the linkage of the pressure rod 432, the push rod 433 and the spring 434, thereby realizing the rapid disassembly and installation of the soil-cutting component 2 and the bamboo shoot cutting component 3. This design not only improves the convenience of operation, but also ensures the stability and safety of the device. The limit button switch 431 can be implemented in many ways, such as a mechanical button switch, an electromagnetic button switch, etc.

[0028] Continue to see Figure 1 In this embodiment, a pressing handle 6 and a carrying handle 7 are provided on the cylinder 11. This design makes it more convenient for the user to operate. The setting of the pressing handle 6 allows the user to better control the downward pressure of the device during use, while the design of the carrying handle 7 makes it convenient for the user to move and carry the device in different occasions. Furthermore, the pressing handle 6 is provided on the side wall of the cylinder 11, which is convenient for the user to press with the palm during operation. The carrying handle 7 can be provided on the top of the cylinder 11, which is convenient for the user to lift the device by hand. The pressing handle 6 and the carrying handle 7 can adopt an ergonomic design, making the user more comfortable during use. In addition, the material of the pressing handle 6 and the carrying handle 7 can be selected from durable and non-slip materials to improve the safety and comfort of use.

[0029] Continue to see Figure 7 and Figure 8 In this embodiment, the lower end of the soil-digging sleeve 21 is a conical structure. The lower end of the soil-digging sleeve 21 is designed to be a conical structure, so that the soil can be broken better during the soil-digging process, which is convenient for the entry and excavation of bamboo shoots. The conical structure can reduce the resistance of the soil, make the soil-digging process smoother, and improve work efficiency.

[0030] Continue to see Fig. 9In this embodiment, the cutting structure 33 is a cutting blade 331, an iris mechanism 332 and a driver. The driver is connected to the bamboo shoot cutting sleeve 31. The input end of the iris mechanism 332 is connected to the driver. The output end of the iris mechanism 332 is connected to multiple cutting blades 331. The multiple cutting blades 331 are circumferentially distributed at the opening 32 of the bamboo shoot cutting sleeve 31. The input end of the iris mechanism 332 is connected to the driver. The driver adjusts the position and angle of the cutting blade 331 by controlling the opening and closing of the iris mechanism 332, thereby realizing the cutting operation of the bamboo shoots. This design can ensure the stability of the cutting process and the uniformity of the cutting effect. Multiple cutting blades 331 are circumferentially distributed at the opening 32 of the bamboo shoot cutting sleeve 31. This arrangement can ensure that the bamboo shoots are cut at multiple points during the cutting process, thereby improving the cutting efficiency. Specifically, the iris mechanism 332 can be accurately controlled by an electric control method, and the driver can be an electric motor or a hydraulic drive device. The cutting blade 331 can be made of high-strength alloy material to ensure sufficient strength and wear resistance during the cutting process. The design of the iris mechanism 332 may refer to the structure of the camera aperture, and the opening and closing degree of the cutting blade 331 may be controlled by adjusting the position of the iris blades, thereby achieving precise cutting of the bamboo shoots.

[0031] In the present embodiment, a detection probe 8 for detecting bamboo shoots is provided in the soil-scraping sleeve 21. The detection probe 8 is used to detect the presence and position of bamboo shoots, so as to more accurately perform soil-scraping and bamboo shoot cutting operations. The detection probe 8 can be an optical sensor, an ultrasonic sensor or other sensors suitable for detecting bamboo shoots. The detection probe 8 is installed inside the soil-scraping sleeve 21 and is connected to the control system through a signal line. The control system determines the position of the bamboo shoots according to the signal of the detection probe 8 and controls the execution of the soil-scraping process.
