Description

Technical Field

[0001] This invention relates to the field of planting technology, and more specifically, to a soil-digging device for facilitating the planting of small pear seedlings. Background Technology

[0002] Pear trees are one of the most common fruit trees. When planting small pear trees or other crops on a large scale, the soil needs to be turned over, which requires a soil turning device. In reality, most soil turning is done with hoes, and sometimes with machinery. Existing soil turning devices only have one set of blades. After turning over the bottom soil, a second turning is required to achieve the desired effect, which is time-consuming and labor-intensive. After turning over the soil, the planted saplings still need to be watered and fertilized manually, which is inefficient.

[0003] To address the aforementioned problems, utility model patent application CN 210641303 U discloses a soil-digging device for facilitating the planting of small pear seedlings. The device includes a support plate and a hollow connector. A bracket is fixed to the lower side of the support plate, and a hydraulic cylinder is installed at the upper left end of the support plate. A hydraulic rod is threaded to the upper end of the hollow connector. A dual-head motor is installed under the support plate, and a mobile battery is positioned between the hydraulic cylinders. A motor is installed on the upper side of a water tank, and a stirring rod is fixed to the lower side of the drive gear. A conveying pipe is installed below the discharge port, and the conveying pipe is connected to a connecting pipe. This soil-digging device for facilitating the planting of small pear seedlings includes a mobile battery and a water tank. The mobile battery provides power to the motor and the dual-head motor, ensuring the normal operation of the entire device. Eight nozzles are installed below the water tank, facilitating the even spraying of organic fertilizer onto the soil, replenishing nutrients without requiring manual fertilization, thus saving time and effort.

[0004] While the aforementioned patent can achieve the function of digging soil using blades, the digging effect is generally poor, and the soil still tends to clump together. Furthermore, the presence of pebbles in the soil can damage the blades and affect the planting and growth of small pear trees or other crops. Therefore, a soil-digging device that facilitates the planting of small pear seedlings is needed. Summary of the Invention

[0005] In view of the problems existing in the prior art, the purpose of this invention is to provide a soil-digging device that facilitates the planting of small pear seedlings.

[0006] To solve the above problems, the present invention adopts the following technical solution.

[0007] A soil-digging device for planting small pear seedlings includes a trolley with a traction device on its outer side.

[0009] The traction device includes four support wheels, and the four support wheels are rotatably connected to the trolley on the side closest to the trolley. Two motors are embedded inside the trolley, and the output shafts of the two motors are fixedly connected to the two support wheels on the right side, respectively.

[0010] As a further description of the above technical solution:

[0011] The slide rod is fitted with a sliding sleeve that is rotatably connected to it, and the bottom of the sliding sleeve is in contact with the fixed barrel.

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention;

[0033] Please see Figures 1-6 In this invention: a soil-digging device for planting small pear seedlings includes a trolley 1, a traction device 2 on the outer side of the trolley 1, a triangular block 3 fixedly connected to the inner wall of the trolley 1, a soil-digging plate 4 slidably connected to the triangular block 3, the left side of the soil-digging plate 4 being inclined downwards, an electric push rod 5 fixedly connected to the triangular block 3, the left end of the electric push rod 5 being fixedly connected to the soil-digging plate 4, an mounting plate 6 fixedly connected to the top of the trolley 1, a drive rod 7 rotatably connected to the mounting plate 6, the drive rod 7 being square, a motor 8 fixedly connected to the top of the mounting plate 6, the output shaft of the motor 8 being fixedly connected to the drive rod 7, a lifting sleeve 9 slidably connected to the drive rod 7, a fixed bucket 10 fixedly connected to the bottom of the mounting plate 6, the top end of the lifting sleeve 9 being inserted into the fixed bucket 10, a rotating disk 11 fixedly connected to the bottom of the fixed bucket 10, and a rotating disk 11 on the rotating disk 11. A screen plate 12 is fixedly connected to the lifting sleeve 9. Two crushing rods 13 are fixedly connected to both the left and right sides of the lifting sleeve 9. Two sliding rods 14 are fixedly connected to the top of the lifting sleeve 9. Two trapezoidal blocks 15 are fixedly connected to the inner bottom wall of the fixed barrel 10. Two discharge holes 16 are opened on the rotating disk 11. An electric push rod 17 is fixedly connected to the top of the rotating disk 11. A sliding plate 18 is fixedly connected to the top of the electric push rod 17. The left and right sides of the sliding plate 18 extend through and to the outside of the lifting sleeve 9. Sealing plates 19 are fixedly connected to both the left and right sides of the sliding plate 18. A round hole 31 is opened at the bottom of the trolley 1. The traction device 2 includes four support wheels 201. The four support wheels 201 are rotatably connected to the trolley 1 on the side closest to the trolley 1. Two motors 202 are embedded inside the trolley 1. The output shafts of the two motors 202 are fixedly connected to the two support wheels 201 on the right side, respectively.

[0034] In this invention, during use, the trolley 1 is first moved to the area where soil needs to be excavated. Then, the user activates the electric push rod 5, which causes the soil-collecting plate 4 to slide along the triangular block 3. As the soil-collecting plate 4 slides, its left side inserts into the soil. By controlling the electric push rod 5, the depth of the soil-collecting plate 4 inserted into the soil can be adjusted, thus controlling the excavation depth. After the soil-collecting plate 4 is adjusted to the appropriate position, the user activates the two motors 202. These motors 202 drive the two right-side support wheels 201 to rotate. The rotation of the support wheels 201 pushes the trolley 1 to move. During the movement of the trolley 1, the soil-collecting plate 4 scoops up the soil, which then slides along the soil-collecting plate 4 into the trolley 1. The soil then falls onto the top of the screen plate 12. Next, the user activates the motor 8, which drives the drive rod 7 to rotate. The rotation of the drive rod 7 then drives the lifting sleeve 9 to rotate. During the rotation of the lifting sleeve 9, the crushing rod 13 rotates. During the process, the clumps of soil are broken up. The broken soil is then filtered by the sieve plate 12, which filters out the clumps of soil and stones. Soil of the appropriate size passes through the sieve plate 12 and falls to the ground through the round hole 31, completing the soil excavation work. As the trolley 1 moves, it excavates the soil in the area it passes through. At the same time, as the lifting sleeve 9 rotates and drives the crushing rod 13 to break up the soil, the sliding rod 14 at the top of the lifting sleeve 9 slides continuously over the top of the two trapezoidal blocks 15. When the sliding rod 14 slides along the inclined surface of the trapezoidal block 15 to its top, it drives the lifting sleeve 9 to rise until it slides over the trapezoidal block 15. At this time, the lifting sleeve 9 will descend rapidly. As the sliding rod 14 slides over the trapezoidal block 15, the lifting sleeve 9 drives the sieve plate 12 to move up and down, improving the soil screening effect of the sieve plate 12 and lifting the soil so that the crushing rod 13 can better break up the soil, thereby improving the working efficiency of the device.

[0035] Please see Figure 5 The slide rod 14 is fitted with a slide sleeve 20 that is rotatably connected to it, and the bottom of the slide sleeve 20 is in contact with the fixed barrel 10.

[0036] In this invention, the sliding sleeve 20 can reduce the friction between the sliding rod 14, the fixed barrel 10, and the trapezoidal block 15, thereby improving the smoothness of the device's operation, reducing wear, and extending the device's service life.

[0037] Please see Figure 5 The drive rod 7 is fitted with a fixed ring 21 that is fixedly connected to it. The outer side of the fixed ring 21 is slidably connected to the lifting sleeve 9. A spring 22 is fixedly connected to the bottom of the fixed ring 21. The bottom end of the spring 22 is fixedly connected to the lifting sleeve 9.

[0038] In this invention, the fixed ring 21 and the spring 22 can drive the lifting sleeve 9 to move downward, so that the lifting sleeve 9 can quickly descend after rising, thereby improving the soil crushing and screening effect.

[0039] Please see Figure 1 , 3 4, wherein: the sieve plate 12 is shaped like a trumpet, and the soil sampling plate 4 is shaped like a U.

[0040] In this invention, the funnel-shaped sieve plate 12 allows the filtered stones to move closer to the center of the rotating disk 11. After the designated area is excavated, the screened stones remain on the top of the sieve plate 12 and roll down onto the rotating disk 11. When the user activates the electric push rod 17, the sealing plate 19 is moved away from the top of the discharge hole 16 via the sliding plate 18. At this time, the stones on the rotating disk 11 are discharged from the discharge hole 16, thus achieving the purpose of discharging the stones.

[0041] Please see Figures 1-4 Among them, two fixing blocks 23 are fixedly connected to the right side of the trolley 1, and a handle 24 is fixedly connected between the two fixing blocks 23.

[0042] In this invention, the fixed block 23 and the handle 24 make it easier for the user to control the trolley 1, thereby improving the practicality of the device.

[0043] Please see Figure 2 Among them, the right side of the trolley 1 is fixedly connected to a controller 25 that controls the opening and closing of the electric push rod 5, the motor 8, the electric push rod 17, and the motor 202.

[0044] In this invention, the controller 25 allows users to easily control the opening and closing of the electric push rod 5, the motor 8, the electric push rod 17, and the motor 202, thereby improving the practicality of the device.

[0045] Please see Figures 1-4 The trolley 1 is fixedly connected to a fixed plate 26 on its left side. A hydraulic push rod 27 is inserted through the fixed plate 26 and fixedly connected to it. A lifting frame 28 is fixedly connected to the bottom end of the hydraulic push rod 27. A crossbar 29 is rotatably connected to the inner side of the lifting frame 28. Cutting discs 30 are arranged at equal intervals on the crossbar 29.

[0046] In this invention, when the soil is being excavated, the hydraulic push rod 27 is activated, which will cause the lifting frame 28 to descend. After the lifting frame 28 descends, the cutting disc 30 on the crossbar 29 will be inserted into the soil. During the movement of the trolley 1, the cutting disc 30 will cut the soil, which will make it easier for the soil extraction plate 4 to extract soil.

[0047] The above are merely preferred embodiments of the present invention; however, the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concept, should be covered within the scope of protection of the present invention.
