[0020] Now, with reference to the attached drawings and preferred embodiments, the present utility model will be further described in detail. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present utility model in a schematic way, so they only show the components related to the present utility model.
[0021] Refer to Figure 1 、 Figure 2 And Figure 3As shown in the figure, the utility model provides a technical solution: a hole digger for walnut planting, which includes a U-shaped plate 1. Both sides of the bottom of the U-shaped plate 1 are fixedly connected with pedals 2. A protective plate 3 is installed on one side of the U-shaped plate 1. Both ends inside the U-shaped plate 1 are fixedly connected with sliding rods 4. The surface of the sliding rod 4 is slidably connected with a sliding plate 5. One side of the sliding plate 5 is fixedly connected with a bracket 6. The other end of the bracket 6 is installed with a driving device 7. The bottom of the driving device 7 is installed with a digging propeller 8. Both sides of the driving device 7 are fixedly connected with grips 9. After the staff places the U-shaped plate 1 at the horizontal ground, step on the pedals 2 and pull the grips 9. By the up and down sliding of the sliding plate 5 on the surface of the sliding rod 4, the grips 9 can control the sliding plate 5 to drive the bracket 6, so that the driving device 7 and the digging propeller 8 move up and down. Use the digging propeller 8 to dig the ground, so as to ensure the levelness of the hole dug by the digging propeller 8, prevent the planting hole from being dug obliquely, and block the soil discharged by the digging of the digging propeller 8 through the shielding of the protective plate 3 on one side of the U-shaped plate 1, preventing the soil from splashing and causing normal harm to the user.
[0022] Referring to Figure 3 As shown in the figure, in this implementation scheme: circular grooves 10 are opened at both ends inside the sliding plate 5. The inner walls of the circular grooves 10 are slidably connected with a number of balls 11. The surface of the balls 11 is slidably connected with the surface of the sliding rod 4. When the staff pulls the sliding plate 5 to move up and down on the surface of the sliding rod 4, through the rotational connection of a number of balls 11 rolling inside the circular groove 10 with the sliding rod 4, when the sliding plate 5 moves, through the contact between the balls 11 and the sliding rod 4, the contact area of the sliding plate 5 moving on the surface of the sliding rod 4 is reduced, and the frictional resistance generated when the sliding plate 5 moves on the surface of the sliding rod 4 is reduced, making the movement of the sliding plate 5 smoother and saving the force required for the staff to pull the sliding plate 5.
[0023] Referring to Figure 3 As shown in the figure, in this implementation scheme: conical scraping plates 12 are fixedly connected to both ends of the top and bottom of the sliding plate 5. The end of the conical scraping plate 12 far from the sliding plate 5 abuts against the surface of the sliding rod 4. When the sliding plate 5 moves up and down, the conical scraping plate 12 moves on the surface of the sliding rod 4. Through the contact of the tip of the conical scraping plate 12 with the surface of the sliding rod 4, the soil attached to the surface of the sliding rod 4 is scraped off while adhering to the surface of the sliding rod 4, thereby improving the cleanliness of the surface of the sliding rod 4 and preventing the soil from clogging the inside of the sliding plate 5.
[0024] Referring to Figure 5 As shown in the figure, in this implementation scheme: a circular hole 13 is opened on one side of the sliding plate 5. A nut 14 is fixedly connected to one side of the protective plate 3. A threaded rod 15 is threadedly connected inside the nut 14. After the staff moves the sliding plate 5 to the designated position, then screw the threaded rod 15 into the circular hole 13 through the nut 14, thereby fixing the position of the sliding plate 5 and the hole digging device installed at the front end, so that the digging propeller 8 and the driving device 7 cannot move up and down through the sliding plate 5 and the sliding rod 4, facilitating the transportation of this device by the staff.
[0025] Refer to Figure 4 As shown, in this embodiment: A number of taper pins 16 are fixedly connected to the bottom of the pedal 2. Through the number of taper pins 16 provided at the bottom of the pedal 2, when the device is placed on the bottom, the taper pins 16 can penetrate into the soil, increasing the friction between the device and the ground and preventing the displacement of the device during operation from affecting the size of the dug hole.
[0026] Refer to Figure 4 As shown, in this embodiment: A number of rubber strips 17 are fixedly connected to the top of the pedal 2. Through the rubber strips 17 provided on the top of the pedal 2, when the worker steps on the pedal 2, the friction between the pedal 2 and the user's shoe sole is increased through the rubber strips 17, preventing the user's foot from slipping when stepping on the pedal 2 and causing the user to fall.
[0027] Refer to Figure 2 As shown, in this embodiment: The cross-sectional shape of the protective plate 3 is an arc structure. Through the arc structure design of the protective plate 3, when the soil splashes onto the surface of the protective plate 3, the arc surface of the protective plate 3 buffers the impact force of the soil, reduces the damage caused by the soil splash to the protective plate 3, absorbs the impact force of the soil, prevents the soil from splashing again, and improves the service life of the protective plate 3.
[0028] Working principle: After the staff places the U-shaped plate 1 at the ground level, step on the pedal 2 and pull the grip 9. The skateboard 5 slides up and down on the surface of the slide bar 4, so that the grip 9 can control the skateboard 5 to drive the bracket 6, enabling the driving device 7 and the excavation propeller 8 to move up and down. Use the excavation propeller 8 to excavate the ground, thereby ensuring the levelness of the pit dug by the excavation propeller 8, preventing the planting pit from being dug obliquely, and shielding the side of the U-shaped plate 1 through the protective plate 3 to shield the soil discharged by the excavation of the excavation propeller 8, preventing the soil from splashing and causing normal harm to the user. When the staff pulls the skateboard 5 to move up and down on the surface of the slide bar 4, through the rotational connection of a number of ball bearings 11 rolling inside the circular groove 10 and the slide bar 4, when the skateboard 5 moves, through the contact between the ball bearings 11 and the slide bar 4, the contact area of the skateboard 5 moving on the surface of the slide bar 4 is reduced, and the frictional resistance generated when the skateboard 5 moves on the surface of the slide bar 4 is reduced, making the skateboard 5 move more smoothly and saving the force required for the staff to pull the skateboard 5. When the skateboard 5 moves up and down, the conical scraper 12 moves on the surface of the slide bar 4. Through the contact of the tip of the conical scraper 12 with the surface of the slide bar 4, it adheres to the surface of the slide bar 4 to scrape the soil attached to the surface of the slide bar 4, thereby keeping the surface of the slide bar 4 clean and preventing the soil from clogging the inside of the skateboard 5. After the staff moves the skateboard 5 to the designated position, then screw the threaded rod 15 into the round hole 13 through the nut 14, thereby fixing the position of the skateboard 5 and the front-mounted pit-digging device, so that the excavation propeller 8 and the driving device 7 cannot move up and down through the skateboard 5 and the slide bar 4, facilitating the transportation of this device by the staff. Through a number of taper pins 16 arranged at the bottom of the pedal 2, when this device is placed at the bottom, the taper pins 16 can penetrate into the soil, increasing the friction between the device and the ground and preventing the displacement of the device during operation from affecting the size of the dug pit. Through the rubber strip 17 arranged at the top of the pedal 2, when the staff steps on the pedal 2, the rubber strip 17 increases the friction between the pedal 2 and the sole of the user, preventing the user's foot from sliding when stepping on the pedal 2 and causing the user to slip. Through the arc-shaped structure design of the protective plate 3, when the soil splashes onto the surface of the protective plate 3, the arc-shaped surface of the protective plate 3 buffers the impact force of the soil, reducing the damage caused by the soil splashing to the protective plate 3, absorbing the impact force of the soil, preventing the soil from splashing again, and prolonging the service life of the protective plate 3.
[0029] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.
