Description

Technical Field

[0001] This utility model relates to the field of river management technology, specifically to a hole-opening device for planting vegetation on the riverbed. Background Technology

[0002] When carrying out riverbed ecological restoration in mountainous areas with gravelly riverbeds, it is usually necessary to first remove large stones and silt from the riverbed, retaining the gravel, and then plant vegetation to enhance the ecological function of the riverbed. When planting submerged plants, holes need to be dug in the riverbed first, and then the plant roots are inserted and back-pressed with gravel to secure them. Simply digging holes manually is time-consuming and labor-intensive, and the efficiency is not high. Currently used hole-drilling tools are difficult to create ideal planting hole depths, and the holes are prone to collapse before the plants are placed in, causing some plants to be washed away or die due to shallow burial depth and exposed roots.

[0003] To solve the above problems, there is a need for a cavity-opening device that is suitable for opening cavities in crushed stone beds, has an appropriate cavity depth, is not prone to collapse, and can open cavities in batches. Utility Model Content

[0004] The purpose of this invention is to provide a hole-opening device for planting vegetation on the riverbed. A drive motor drives a rotating shaft to rotate, which in turn drives a drill bit to rotate. The drill bit penetrates deep into the gravel, and then a connecting plate moves down, causing a collar to move down, which in turn moves a connecting rod to support a protective plate. This causes the support plate to expand outward, increasing the outer diameter of the protective plate. Together with the drill bit, the gravel is pushed outward, forming holes within the gravel for planting vegetation on the riverbed, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a hole-opening device for planting vegetation on the riverbed, comprising: a rotating shaft, a drill bit fixed at the bottom of the rotating shaft, four sets of protective plates rotatably connected around the top of the drill bit via a movable shaft, multiple sets of protrusions for pushing pebbles and stones fixed on the outer side of the protective plates, a collar movably sleeved on the outer side of the rotating shaft, a connecting rod movably connected around the collar, the end of the connecting rod away from the collar being rotatably connected to the inner side of the protective plate, and a round tube sleeved on the outer side of the rotating shaft, the round tube being located above the collar, and a connecting plate fixed at the top of the round tube;

[0006] It also includes a drive motor for driving the rotating shaft. The drive motor is installed inside the housing. The output shaft of the drive motor passes through the lower end of the housing and is fixedly connected to the rotating shaft. An adjustment component for adjusting the vertical movement of the connecting plate is also provided on the outside of the housing.

[0007] Preferably, a limiting groove is formed on the outer side of the rotating shaft, and the collar extends to the inner side of the limiting groove.

[0008] Preferably, a protective cover is fixed to the outside of the collar, and the protective cover is located on top of the protective plate.

[0009] Preferably, it further includes a first support plate and a second support plate for connecting multiple main structures. A bearing is fixedly installed on the first support plate, and a sleeve is fixedly connected to the inner ring of the bearing. The sleeve is detachably connected to the rotating shaft, and the second support plate is detachably connected to the connecting plate.

[0010] Preferably, a first mounting screw is threaded onto the sleeve, the first mounting screw penetrates into the interior of the sleeve and is threaded onto the rotating shaft, and a second mounting screw is threaded onto the top of the second support plate, the second mounting screw penetrates the second support plate and is threaded onto the connecting plate.

[0011] Preferably, it also includes sprockets fixed to the outside of the rotating shaft, and chains are rotatably connected to the outside of the sprockets on the outside of adjacent sets of rotating shafts.

[0012] Preferably, a wear-resistant rubber sheet is fixed to one side of the protective plate facing each other, and the wear-resistant rubber sheet is folded inward and recessed along the center line.

[0013] Preferably, the adjustment assembly includes a fixed handle fixed to the outside of the housing, an adjustment rod passing through the handle, the bottom of the adjustment rod being fixedly connected to a connecting plate, and an electric push rod fixed to the top of the handle, the piston rod of the electric push rod being fixedly connected to the top of the adjustment rod.

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

[0015] 1. This utility model uses a drive motor to drive a rotating shaft and a drill bit, allowing the drill bit to penetrate deep into the gravel at the bottom of the river. Then, under the pressure of the adjusting rod, the circular tube is squeezed, and the circular tube drives the collar to move down, which in turn drives the connecting rod to support the protective plate, causing the protective plate to expand outward and increase its outer diameter. This facilitates pushing the gravel outward. In conjunction with the rotation of the rotating shaft, the size of the hole is enlarged. At the same time, multiple main structures can be connected, allowing multiple holes to be dug simultaneously using one drive motor, thus improving the efficiency of hole-digging for planting vegetation at the bottom of the river.

[0016] 2. This utility model uses wear-resistant rubber sheets to connect adjacent protective plates to prevent gravel from getting stuck between the protective plates when the rotating shaft rotates, thus preventing the protective plates from closing. Attached Figure Description

[0023] 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.

[0024] This utility model provides, for example Figures 1-3 The device shown is for planting vegetation on the riverbed. It includes: a rotating shaft 1, a drill bit 2 fixed at the bottom of the rotating shaft 1, four sets of protective plates 3 rotatably connected around the top of the drill bit 2 via a movable shaft, multiple sets of protrusions 4 for pushing stones and rocks fixed on the outer side of the protective plates 3, a collar 5 movably sleeved on the outer side of the rotating shaft 1, a connecting rod 6 movably connected around the collar 5, the end of the connecting rod 6 away from the collar 5 being rotatably connected to the inner side of the protective plate 3 via a connecting seat, a round tube 7 sleeved on the outer side of the rotating shaft 1, the round tube 7 being above the collar 5, and the inner diameter of the round tube 7 being smaller than the outer diameter of the collar 5, and a connecting plate 8 fixed at the top of the round tube 7.

[0025] It also includes a drive motor 9 that drives the rotating shaft 1. The drive motor 9 is installed inside the housing 10. The output shaft of the drive motor 9 passes through the lower end of the housing 10 and is fixedly connected to the rotating shaft 1. A handle 11 is fixed on the outside of the housing 10. An adjusting rod 12 passes through the handle 11. The bottom of the adjusting rod 12 is fixedly connected to the connecting plate 8. An electric push rod 13 is fixed on the top of the handle 11. The piston rod of the electric push rod 13 is fixedly connected to the top of the adjusting rod 12.

[0026] The drive motor 9 drives the rotating shaft 1 and the drill bit 2 to rotate, causing the drill bit 2 to penetrate deeper into the gravel at the bottom of the river. Then, the adjusting rod 12 is pressed down by the electric push rod 13 to squeeze the round tube 7. Subsequently, the round tube 7 contacts the collar 5 and drives the collar 5 to move down, which drives the connecting rod 6 to support the protective plate 3, causing the protective plate 3 to expand outward and increase its outer diameter, making it easier to push the gravel outward. In conjunction with the rotation of the rotating shaft 1, the size of the cavity is expanded.

[0027] Among them, such as Figure 3 As shown:

[0028] A limiting groove 14 is provided on the outer side of the rotating shaft 1, and the collar 5 extends to the inner side of the limiting groove 14. The limiting groove 14 is provided to facilitate the limiting of the collar 5, preventing the collar 5 from rotating and causing the connecting rod 6 to bend, thus failing to support the protective plate 3.

[0029] Furthermore, such as Figure 1 As shown:

[0030] A protective cover 15 is fixed to the outside of the collar 5. The protective cover 15 is located on the top of the protective plate 3. With the setting of the protective cover 15, it can move down and get closer to the protective plate 3 as the collar 5 moves down, covering the top of the protective plate 3 and preventing debris in the water from entering the inside of the protective plate 3.

[0031] At the same time, multiple main structures can be connected, and multiple holes can be opened simultaneously using a single drive motor 9, thereby improving the efficiency of hole opening for planting vegetation on the riverbed.

[0032] Preferred, such as Figure 4-5 As shown:

[0033] It also includes a first support plate 16 and a second support plate 17 for connecting multiple main structures. A bearing is fixedly installed on the first support plate 16, and a sleeve 18 is fixedly connected to the inner ring of the bearing. The sleeve 18 is detachably connected to the rotating shaft 1, and the second support plate 17 is detachably connected to the connecting plate 8. Through the first support plate 16 and the second support plate 17, it is convenient to connect multiple rotating shafts 1 and the connecting plate 8 to maintain the stability of the device. At the same time, by using the sleeve 18 to connect the rotating shaft 1 to the first support plate 16, the rotation of the rotating shaft 1 can be maintained, and it is also convenient to disassemble and assemble.

[0034] It is worth noting that, such as Figure 4-5 As shown:

[0035] A first mounting screw 19 is threaded onto the sleeve 18. The first mounting screw 19 passes through the inside of the sleeve 18 and is threaded onto the rotating shaft 1. A second mounting screw 20 is threaded onto the top of the second support plate 17. The second mounting screw 20 passes through the second support plate 17 and is threaded onto the connecting plate 8. The first mounting screw 19 and the second mounting screw 20 facilitate the connection between the sleeve 18 and the rotating shaft 1, as well as the fixation between the second support plate 17 and the connecting plate 8.

[0036] In a further preferred embodiment, such as Figure 5 As shown:

[0037] It also includes a sprocket 21 fixed on the outside of the rotating shaft 1. The outer sides of the sprockets 21 of two adjacent sets of rotating shafts 1 are rotatably connected to the chains 22. Through the cooperation of the sprockets 21 and the chains 22, it is convenient to make multiple sets of rotating shafts 1 rotate synchronously. Using a set of drive motors 9, multiple sets of acupoints can be opened.

[0038] In addition, such as Figure 1-2 As shown:

[0039] A wear-resistant rubber sheet 23 is fixed on the opposite side of the adjacent protective plates 3. The wear-resistant rubber sheet 23 is folded inward along the center line and recessed. The wear-resistant rubber sheet 23 connects the two adjacent sets of protective plates 3 and maintains the sealing of the protective plates 3 during the opening and closing process.

[0040] In practical use, when using a single main structure: connect the rotating shaft 1 to the output shaft of the drive motor 9, then place the device in river water, place the drill bit 2 in the gravel, start the drive motor 9, the drive motor 9 drives the rotating shaft 1 to rotate, and then the rotating shaft 1 drives the drill bit 2 to penetrate deeper into the gravel. At the same time, the electric push rod 13 drives the adjusting rod 12 to move downward, and the adjusting rod 12 drives the connecting plate 8 to move downward. The connecting plate 8 drives the round tube 7 to move downward, pressing the collar 5 downward. The collar 5 moves downward along the limiting groove 14, and then the collar 5 drives the connecting rod 6 to support the protective plate 3, causing the protective plate 3 to expand outward. As the protective plate 3... As the acupoint expands, the wear-resistant rubber sheet 23 is opened, and the protective plate 3 pushes out the surrounding gravel as the rotating shaft 1 rotates, expanding the acupoint and preventing it from being refilled by gravel. When multiple main structures need to be used at the same time: the rotating shaft 1 is fitted into the sleeve 18, and the sleeve 18 is connected to the rotating shaft 1 using the first mounting screw 19. Then, the second support plate 17 is connected to the connecting plate 8 using the second mounting screw 20. The output shaft of the drive motor 9 is then connected to a set of rotating shafts 1, and the adjacent rotating shafts 1 are connected to the chain 22 through the sprocket 21, so that a set of drive motors 9 can synchronously drive multiple sets of rotating shafts 1 to rotate.
