Description

Technical Field

[0001] This utility model relates to the field of garden planting equipment technology, and in particular to a pit-digging device for garden planting. Background Technology

[0002] The significance of planting hole digging devices for garden planting lies in their ability to efficiently and accurately excavate suitable holes for planting seedlings in garden land, facilitating the planting of garden trees, ensuring that trees have a good foundation for growth, and improving the efficiency and quality of garden planting work.

[0003] In the prior art, Chinese utility model patent application number CN202021801507.4 discloses a hole-digging device for garden planting. The device has a bracket fixedly connected to the base, a cylinder fixedly connected to the bracket, a drive motor fixedly connected to the bracket, a rotating rod fixedly connected to the drive motor, a drill rod connected to the rotating rod, and a spiral blade provided on the outer wall of the drill rod. A connecting plate is fixedly connected below the cylinder, and the drive motor is fixedly connected to the connecting plate. A guide assembly is provided between the base and the connecting plate. The guide assembly includes a guide cylinder and a guide rod. The guide cylinder is vertically set and fixedly connected to the base. The guide rod is vertically set, with its top end fixedly connected to the connecting plate and its bottom end extending into the guide cylinder, which has a certain effect on improving the stability of the hole-digging device. However, this technology has two main drawbacks: Firstly, the device relies on pulleys under the base for support. During the digging process, especially on uneven ground, this affects the accuracy of the digging, making it difficult to control the depth and shape of the pit. This is not conducive to the upright growth of the planted saplings. Moreover, the pulley support method is prone to displacement due to uneven force during digging, further compromising the accuracy of the digging and making it difficult to achieve the desired planting results, thus affecting the overall planning and aesthetics of the garden. Secondly, the device cannot effectively control the depth of the pit. If the pit is dug too deep, it is detrimental to the root growth of the saplings, which may prevent the roots from extending normally or cause root rot due to water accumulation, affecting the survival rate of the trees. If the pit is dug too shallow, it cannot provide enough space for the roots to grow, making the saplings prone to lodging during growth, which is not conducive to the long-term stable growth of the trees.

[0004] In summary, existing technologies have shortcomings in terms of the stability and depth control of planting hole digging devices for gardens, and further improvements and optimizations are needed. Therefore, we propose a planting hole digging device for gardens to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a hole-digging device for garden planting. By using this device, the existing problems in the background art mentioned above can be solved.

[0006] To achieve the above objectives, the technical solution provided by this utility model is as follows: a hole-digging device for garden planting, comprising a base, a bracket installed at the top of the base, symmetrical limiting grooves provided on the inner sides of the two columns of the bracket, a limiting component slidably connected in the limiting groove, a first driving component for moving the limiting component provided on the bracket, an electric push rod provided at the bottom end of the bracket beam, connecting rods provided on both sides of the extension end of the electric push rod, the end of the connecting rod away from the electric push rod being located in the limiting groove above the limiting component, a hole-digging mechanism fixedly connected to the extension end of the electric push rod, and leg seats evenly distributed and fixed at the four ends of the base, a sliding groove provided at the bottom end of the leg seat, a hollow support leg slidably connected in the sliding groove, a protruding nail provided at the bottom end of the support leg, and a second driving component for moving the support leg provided in the leg seat.

[0007] Preferably, the limiting component includes a stop block that is slidably connected in a limiting groove, and a damper is provided on the top of the stop block.

[0008] Preferably, the first drive assembly includes a protective shell disposed at the top of the support beam. A first lead screw is rotatably connected between the inner wall of the top of the protective shell and the inner wall of the bottom of the limiting groove. The outer surface of the first lead screw is threadedly connected to a stop block. A worm gear is fixedly connected to the outer surface of the first lead screw in the protective shell. A worm is meshed with one side of the worm gear. The worm is rotatably connected to the inner walls of both sides of the protective shell. One end of the worm passes through the inner wall of the protective shell and is coaxially fixedly connected to a first handle.

[0009] Preferably, a collar is fixedly connected to the end of the connecting rod away from the electric actuator, and the collar is slidably connected to the outer surface of the first lead screw above the damper.

[0010] Preferably, the digging mechanism includes a motor frame, which is fixedly installed at the extension end of the electric push rod. A drive motor is installed in the motor frame, and the output end of the drive motor is fixedly connected to a helical blade rod through the motor frame.

[0011] Preferably, the second drive assembly includes a mounting plate, which is fixedly connected to the inner wall of the slide. A first bevel gear is rotatably connected to the top of the mounting plate, and a second bevel gear is meshed with the first bevel gear. A rotating rod is fixedly connected to the second bevel gear, and the rotating rod is rotatably connected to the inner wall of the slide. One end of the rotating rod passes through the inner wall of the slide and is coaxially fixedly connected to a second handle. A second lead screw is fixedly connected to the first bevel gear, passing through the mounting plate. The outer surface of the second lead screw is threadedly connected to the top wall of the support leg.

[0012] Preferably, a scale is provided on the support column on one side of the limiting groove, and a horizontal and vertical level is provided on the top of the base.

[0013] Preferably, pulleys are rotatably connected to both sides of the rear end of the bracket, and handrails are fixedly installed on both sides of the bracket.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. Enhanced digging stability: Leg seats are installed at the four ends of the base, with sliding grooves in the legs connecting to the hollow legs. Protruding nails are installed at the bottom of the legs, allowing the height of the legs to be adjusted using the second drive assembly according to different ground conditions. This ensures stable support even on uneven ground, adapting to various complex terrains and effectively preventing the device from shaking due to uneven ground during digging, greatly enhancing the stability of the entire digging device during operation. Symmetrical limiting grooves are provided on the inner sides of the two columns of the support frame, with sliding connections to limiting components. One end of the connecting rod is connected to the extension end of the electric push rod, and the other end is slidably connected to the first lead screw in the limiting groove above the limiting component via a collar. During digging, this ensures more stable vertical movement of the electric push rod and the digging mechanism, reducing lateral deviation and further improving the overall stability of the device, which is beneficial for improving the accuracy and quality of digging.

[0016] 2. Effective control of the digging depth: Through the precise control of the limiting component by the first drive component, the height of the digging mechanism can be indirectly adjusted. The cooperation of the worm gear, worm wheel, and first lead screw in the first drive component allows the operator to adjust the position of the stop block within the limiting groove by turning the first handle. Due to the linkage between the connecting rod and the stop block, the working stroke of the digging mechanism at the extension end of the electric actuator can be accurately controlled. Furthermore, a scale is installed on the support column on one side of the limiting groove, allowing the operator to intuitively refer to the scale when adjusting the height of the limiting component, ensuring that the digging depth meets the planting requirements. This effectively avoids the problem of digging too deep or too shallow a hole, providing suitable growth space for the seedling roots, which is conducive to the vigorous growth of the seedlings and improves the quality of landscaping planting and the survival rate of the seedlings.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.

[0024] Combination Figures 1-4 A planting hole digging device for landscaping includes a base 1, a support 2 mounted on the top of the base 1, symmetrical limiting grooves 3 on the inner sides of the two uprights of the support 2, limiting components 4 slidably connected in the limiting grooves 3, a first drive component 5 for moving the limiting components on the support 2, an electric push rod 6 at the bottom of the crossbeam of the support 2, connecting rods 7 on both sides of the extended end of the electric push rod 6, and the end of the connecting rod 7 away from the electric push rod 6 being located in the limiting groove 3 above the limiting component 4. The position of the limiting component 4 is adjusted by the first drive component 5. The maximum working stroke of the extension end of the electric actuator 6 is then determined, and the digging depth is then set. The extension end of the electric actuator 6 is fixedly connected to the digging mechanism 8. The four ends of the base 1 are evenly fixed with leg seats 9. The bottom end of the leg seat 9 is provided with a sliding groove 10. A hollow support leg 11 is slidably connected in the sliding groove 10. The bottom end of the support leg 11 is provided with a protruding nail 12. The second drive assembly 13 for moving the support leg 11 is provided in the leg seat 9. The height of each support leg 11 is adjusted by operating the second drive assembly 13, thereby completing the adjustment of the support height of the device.

[0025] The limiting component 4 includes a stop 41, which is slidably connected in the limiting groove 3. A damper 42 is provided on the top of the stop 41. The damper 42 can play a buffering role, ensuring the stability of the device during the digging process, and at the same time preventing damage to the threads of the first lead screw 52.

[0026] The first drive assembly 5 includes a protective shell 51, which is located at the top of the crossbeam of the support 2. A first lead screw 52 is rotatably connected between the inner wall of the top of the protective shell 51 and the inner wall of the bottom of the limiting groove 3. The outer surface of the first lead screw 52 is threadedly connected to the stop block 41. A worm gear 53 is fixedly connected to the outer surface of the first lead screw 52 in the protective shell 51. A worm 54 is meshed with one side of the worm gear 53. The worm 54 is rotatably connected to the inner walls of both sides of the protective shell 51. One end of the worm 54 passes through the inner wall of the protective shell 51 and is coaxially fixedly connected to a first handle 55. By rotating the first handle 55, the worm 54 is driven to rotate, thereby driving the worm gear 53 and the first lead screw 52 to rotate. When the first lead screw 52 rotates, the stop block 41 is driven to slide up and down in the limiting groove 3 through the thread transmission principle.

[0027] A collar 71 is fixedly connected to the end of the connecting rod 7 away from the electric push rod 6. The collar 71 is slidably connected to the outer surface of the first lead screw 52 above the damper 42. During the process of the electric push rod 6 pushing the digging mechanism 8 to move up and down, the connecting rod 7 slides on the first lead screw 52 through the collar 71, which ensures that the extension of the electric push rod 6 is effectively limited and determines the maximum working stroke of the extension end of the electric push rod 6. At the same time, the extension end of the electric push rod 6 is supported laterally by the connecting rod 7, which ensures that the electric push rod and the digging mechanism move more stably in the vertical direction and reduces lateral offset.

[0028] The digging mechanism 8 includes a motor frame 81, which is fixedly installed at the extension end of the electric push rod 6. A drive motor 82 is installed in the motor frame 81. The output end of the drive motor 82 passes through the motor frame 81 and is fixedly connected to a helical blade rod 83. After the drive motor 82 is started, the drive motor 82 drives the helical blade rod 83 to rotate at high speed. During the rotation, the helical blade rod 83 cuts into the soil and discharges the soil upward or to the surroundings, thereby realizing the function of digging a hole.

[0029] The second drive assembly 13 includes a mounting plate 131, which is fixedly connected to the inner wall of the slide 10. A first bevel gear 132 is rotatably connected to the top of the mounting plate 131. A second bevel gear 133 is meshed with the first bevel gear 132. A rotating rod 134 is fixedly connected to the second bevel gear 133. The rotating rod 134 is rotatably connected to the inner wall of the slide 10. One end of the rotating rod 134 passes through the inner wall of the slide 10 and is coaxially fixedly connected to a second handle 135. A second handle 135 is fixedly connected to the first bevel gear 132. The second lead screw 136 passes through the mounting plate 131. The outer surface of the second lead screw 136 is threadedly connected to the top wall of the support leg 11. Rotating the second handle 135 drives the rotating rod 134 to rotate, which in turn drives the second bevel gear 133 and the first bevel gear 132 to rotate. The second lead screw 136 passing through the mounting plate 131 is fixedly connected in the first bevel gear 132. The second lead screw 136 is threadedly connected to the top wall of the support leg 11. When the second lead screw 136 rotates, the support leg 11 moves up and down in the slide groove 10.

[0030] A scale is installed on the support column 2 on one side of the limiting groove 3. The position of the stop 41 and the damper 42 is determined by observing the scale. A level is installed on the top of the base 1 both horizontally and vertically. The device is judged to be in a horizontal state by observing the level.

[0031] The rear ends of the bracket 2 are rotatably connected to pulleys 21, and the sides of the bracket are fixedly installed with handrails 22 to facilitate the movement of the device on the ground.

[0032] Working principle:

[0033] First, based on the flatness of the work site, the height of the outriggers 11 is adjusted by operating the second drive assembly 13. Specifically, the second handle 135 is rotated, which drives the rotating rod 134 to rotate. The second bevel gear 133 on the rotating rod 134 drives the first bevel gear 132 to rotate, thereby causing the second lead screw 136 to rotate. Since the second lead screw 136 is threadedly connected to the top wall of the outriggers 11, the outriggers 11 slide up and down in the slide groove 10 until all the protrusions 12 of the outriggers 11 are firmly in contact with the ground, keeping the device horizontal and stable. The device can be judged to be horizontal by observing the level at the top of the base 1.

[0034] Then, based on the required depth of the pit to be dug, the position of the limiting component 4 is adjusted by operating the first drive component 5, thereby determining the maximum working stroke of the extension end of the electric actuator 6. Specifically, the first handle 55 is rotated, which drives the worm 54 to rotate. The worm 54 meshes with the worm wheel 53, thereby driving the first lead screw 52 to rotate. Since the first lead screw 52 is threadedly connected to the stop block 41, the stop block 41 and the damper 42 slide in the limiting groove 3. At the same time, the position of the stop block 41 and the damper 42 can be determined by observing the scale on the column of the bracket 2 on one side of the limiting groove 3, thereby determining the maximum working stroke of the extension end of the electric actuator 6, and thus setting the pit depth.

[0035] Next, the drive motor 82 in the digging mechanism 8 is started. The drive motor 82 drives the spiral blade rod 83 to rotate. At the same time, the electric push rod 6 is operated to extend it, which drives the spiral blade rod 83 to move downward to start digging. When the collar 71 at the top of the connecting rod 7 abuts against the damper 42, it indicates that the spiral blade rod 83 has reached the set depth and the digging of one pit is completed.

[0036] If it is necessary to move the device to the next digging location, use the pulleys 21 on both sides of the rear end of the support 2 to move the device by pushing the handle 22, and then repeat the above steps to dig the next pit.
