Description

Technical Field

[0001] This utility model relates to the field of tobacco seedling transplanting hole drilling technology, specifically to a well-type tobacco seedling transplanting hole drilling device. Background Technology

[0002] The flue-cured tobacco well-cellar transplanting technique refers to a transplanting method that uses specialized tools, such as transplanting hole punchers, to create well-cellars of suitable size on the ridges, and then transplants seedlings of appropriate age into the well-cellars. This technique has the advantages of advancing the transplanting period (7-10 days), increasing the concentration of tobacco leaf transplanting (one person can transplant 2-3 acres per day), promoting early and rapid growth (the well-cellars are warm and humid), truly achieving deep planting of tobacco seedlings (planted deep and buried deep), and reducing seedling raising procedures (no or minimal leaf pruning).

[0003] Publication No. CN206078020U discloses a new type of well-cellar type tobacco seedling transplanting hole drilling machine, which drives the drill bit to rotate through the drive rod, uses the conical section of the drill bit to form a well cellar on the ridge, and sets up water chambers on the drill bit to inject water into the well cellar during the drilling process, which is beneficial to the shaping of the well cellar.

[0004] However, the depth of the well pit is usually greater than the overall height of the drill bit. During the drilling process, the conical section of the drill bit is completely inserted into the well pit to ensure that the upper part of the well pit is a relatively regular cylindrical shape. As a result, the drilling machine can only drill well pits with a fixed inner diameter, and its versatility needs to be improved. Utility Model Content

As a result, the drilling machine can only drill wells with a fixed inner diameter, and its versatility needs to be improved.

[0006] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution:

[0007] This utility model provides a well-type tobacco seedling transplanting hole punch, comprising:

[0008] Installation Department;

[0009] A drive unit, connected to the mounting unit, is used to drive the mounting unit to rotate;

[0010] A scraper is movably mounted on the mounting portion, and its direction of movement intersects the rotation axis of the mounting portion; and

The locking structure is disposed between the adjustment member and the mounting part for locking the adjustment member to the mounting part and for unlocking the adjustment member. The elastic member connects the scraper and the mounting part.

[0013] In some embodiments, the direction of movement of the adjusting member coincides with the rotation axis of the mounting portion, and it has a pressing surface on the side near the scraper. The pressing surface is inclined toward the scraper from one end near the mounting portion to one end away from the mounting portion and presses against the scraper.

[0014] In some embodiments, the scraper has an arc-shaped guide surface on the side near the adjusting member, and the arc-shaped guide surface slides in contact with the pressing surface.

[0015] In some embodiments, a plurality of scrapers are provided, and the plurality of scrapers surround the periphery of the adjusting member; a plurality of elastic members are provided, and the plurality of elastic members correspond one-to-one with the plurality of scrapers; each elastic member connects the mounting part to the corresponding scraper.

[0016] The outer diameter of the adjusting member gradually expands from the end near the mounting part to the end away from the mounting part, so that the pressing surface is arranged in a ring shape, and the pressing surface presses against the plurality of scrapers.

[0017] In some embodiments, the mounting portion is provided with a guide shaft facing the adjusting member, the adjusting member is provided with a guide hole for the guide shaft to pass through, and is sleeved on the guide shaft through the guide hole;

[0021] In some embodiments, one of the scraper and the mounting part is provided with a slide rail, and the other is provided with a slide groove through which the slide rail slides, the slide rail and the slide groove extending along the direction of movement of the scraper.

[0022] In some embodiments, the scraper has two blades, one of which extends along the rotational axis of the mounting portion and is located on the outside of the scraper, and the other extends along the direction of movement of the scraper and is located on the side of the scraper closer to the mounting portion.

[0023] In some embodiments, the outer diameter of the mounting portion is gradually reduced in a direction away from the scraper.

[0024] Compared with existing technologies, the well-type tobacco seedling transplanter provided by this utility model can adjust the distance between the scraper and the rotating axis of the mounting part by driving the scraper to move along the direction intersecting the rotation axis of the mounting part during operation. The scraper is then fixed in the adjusted position by the adjustment part, and the mounting part is driven to rotate by the drive part, which in turn moves the scraper and uses its part extending outside the mounting part to drill holes. Since the distance between the rotation axis of the scraper and the mounting part is the inner diameter of the well, the position of the scraper can be adjusted according to the required inner diameter of the well, thus enabling the drilling of wells with various inner diameters and providing good versatility.

[0037] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0038] To address the technical problem in existing technologies where the depth of the borehole is typically greater than the overall height of the drill bit, and the conical section of the drill bit must fully enter the borehole during drilling to ensure the upper part of the borehole is a relatively regular cylinder, thus limiting the drilling machine to boreholes with a fixed inner diameter and hindering its versatility, this invention provides a borehole-type tobacco seedling transplanting borehole drill. The distance between the scraper and the rotation axis of the mounting part is the inner diameter of the borehole. Therefore, the position of the scraper can be adjusted according to the required inner diameter of the borehole, enabling the drilling of boreholes with various inner diameters and improving versatility.

[0039] Please see Figures 1 to 3 , Figures 1 to 3This is a schematic diagram of the structure of a well-type tobacco seedling transplanter according to one embodiment of the present invention. The well-type tobacco seedling transplanter includes an installation part 1, a driving part 2, a scraper 3, and an adjusting part 4. The driving part 2 is connected to the installation part 1 and is used to drive the installation part 1 to rotate. The scraper 3 is movably installed on the installation part 1, and its direction of movement intersects the rotation axis of the installation part 1. The adjusting part 4 is installed on the installation part 1 and connected to the scraper 3, and is used to drive the scraper 3 to move in the direction intersecting the rotation axis of the installation part 1, and can maintain the scraper 3 at any position during its movement stroke. Specifically, in this design, the scraper 3 can extend at least partially beyond the installation part 1 when it is in motion.

[0040] The well-type tobacco seedling transplanter provided by this utility model can, during operation, drive the scraper 3 to move along the direction intersecting the rotation axis of the mounting part 1 via the adjusting part 4, thereby adjusting the distance between the scraper 3 and the rotation axis of the mounting part 1. The adjusting part 4 then fixes the scraper 3 in the adjusted position. The driving part 2 then drives the mounting part 1 to rotate, causing the scraper 3 to move and drill holes using its portion extending outside the mounting part 1. Since the distance between the scraper 3 and the rotation axis of the mounting part 1 is the inner diameter of the well, the position of the scraper 3 can be adjusted according to the required inner diameter of the well, thus enabling the drilling of wells with various inner diameters, providing good versatility. Specifically, in this design, the direction of movement of the scraper 3 is radial to the mounting part 1.

[0041] It should be noted that, in one embodiment, the drive unit 2 is a drive rod, which drives the mounting part 1 to rotate by manually applying external force. In another embodiment, the drive unit 2 is configured as a mounting arm, a gear, a rack, and a linear motor. The mounting part 1 is mounted on the mounting arm, and the gear is mounted on the mounting part 1. The rack meshes with the gear, and the linear motor is mounted on the mounting part 1, driving the rack to move linearly, thereby realizing the rotation of the mounting part 1.

[0042] In yet another embodiment, please refer to Figure 4 The drive unit 2 includes a mounting frame 21 and a drive motor 22. The mounting unit 1 is rotatably mounted on the mounting frame 21. The drive motor 22 is mounted on the mounting frame 21, and its rotor is connected to the mounting unit 1. When rotating, it drives the mounting unit 1 to rotate.

[0043] In addition, it should be noted that the adjustment unit 4 can be configured as a hydraulic rod, an electric actuator, a linear motor, or other forms.

[0044] In one embodiment, the adjustment part 4 includes an adjustment member 41, a locking structure 42, and an elastic member 43. The adjustment member 41 is movably mounted on the mounting part 1 and connected to the scraper 3. When in motion, it can drive the scraper 3 to move relative to the mounting part 1. The locking structure 42 is disposed between the adjustment member 41 and the mounting part 1 and is used to lock the adjustment member 41 to the mounting part 1 and to unlock the adjustment member 41. The elastic member 43 is connected to the scraper 3 and the mounting part 1 and is used to drive the scraper 3 to retract into the mounting part 1.

[0045] In this embodiment, the scraper 3 is driven to move towards the periphery of the mounting part 1 by the adjusting member 41, thereby increasing the distance between it and the rotational axis of the mounting part 1, and the adjusting member 41 is maintained in any position by the locking structure 42. At the same time, after the adjusting member 41 is unlocked, the scraper 3 automatically retracts into the mounting part 1 under the action of the elastic member 43, improving convenience.

[0046] It should be noted that the elastic element 43 can be a compression spring, a rubber band, or a gas spring, etc. Specifically, in this embodiment, the elastic element 43 is set in the form of a compression spring.

[0047] In one embodiment, the direction of movement of the adjusting member 41 coincides with the rotation axis of the mounting part 1, and it has a pressing surface 411 on the side near the scraper 3. The pressing surface 411 is inclined towards the scraper 3 from the end near the mounting part 1 to the end away from the mounting part 1 and presses against the scraper 3.

[0048] In this embodiment, when the adjusting member 41 moves along the rotation axis of the mounting part 1, the pressing surface 411 slides against the scraper 3. Since the pressing surface 411 is inclined as described above, the scraper 3 gradually moves towards the outside of the mounting part 1, increasing the distance between the scraper 3 and the rotation axis of the mounting part 1.

[0049] In one embodiment, the scraper 3 has an arc-shaped guide surface 31 on the side near the adjusting member 41, and the arc-shaped guide surface 31 slides in contact with the pressing surface 411.

[0050] In this embodiment, the scraper 3 is provided with an arc-shaped guide surface 31 corresponding to the pressing surface 411, so that the adjustment member 41 drives the scraper 3 to move more smoothly and improves convenience.

[0051] In one embodiment, please refer to Figures 5 to 8 Multiple scrapers 3 are provided, and multiple scrapers 3 are arranged around the periphery of the adjusting member 41. Multiple elastic members 43 are provided, and multiple elastic members 43 correspond one-to-one with multiple scrapers 3. Each elastic member 43 connects the mounting part 1 and the corresponding scraper 3. The outer diameter of the adjusting member 41 is gradually widened from the end near the mounting part 1 to the end away from the mounting part 1, so that the pressing surface 411 is arranged in a ring shape, and the pressing surface 411 presses against multiple scrapers 3.

[0052] In this embodiment, the pressing surface 411 is set as an annular shape and simultaneously presses against multiple scrapers 3. Thus, when the adjusting member 41 moves close to the mounting part 1, it can simultaneously drive multiple scrapers 3 to move outward from the mounting part 1, thereby improving drilling capability while ensuring convenient adjustment.

[0053] Specifically, in this solution, the adjusting member 41 has a pressing section forming a pressing surface 411 and a threaded section with internal threads, and the pressing section and the threaded section are connected.

[0054] It should be noted that the adjusting member 41 can be configured as an adjusting seat, adjusting cylinder, or adjusting plate. Furthermore, in one embodiment, the locking structure 42 is configured as a bolt, and a slot is provided on the mounting part 1. A screw hole is provided on the side wall of the slot, and the adjusting member 41 is located in the screw hole. The bolt is screwed into the screw hole and presses against the adjusting member 41. In another embodiment, the locking structure 42 is configured as an electromagnet. The adjusting member 41 slides against the electromagnet seat, and when the adjusting member 41 slides to a preset position, the electromagnet is activated to attract the adjusting member 41.

[0055] In another embodiment, the mounting part 1 is provided with a guide shaft 11 facing the adjustment member 41, the adjustment member 41 is provided with a guide hole 41a for the guide shaft 11 to pass through, and is sleeved on the outside of the guide shaft 11 through the guide hole 41a; the locking structure 42 is a thread provided on the inner wall of the guide shaft 11 and the guide hole 41a respectively.

[0056] In this embodiment, the adjusting member 41 is sleeved on the guide shaft 11, and the locking and unlocking between the adjusting member 41 and the guide shaft 11 are achieved through a threaded engagement. The structure is simple and the operation is convenient. It should be noted that in this solution, the outer wall of the guide shaft 11 is provided with a scale line 117 along its axial direction. This scale line 117 indicates the distance between the scraper 3 and the rotation axis of the mounting part 1 through the adjusting member 41, so as to facilitate adjustment. The outer wall of the guide shaft 11 is provided with external threads, and the inner wall of the guide hole 41a is provided with internal threads.

[0057] In one embodiment, the inner wall of the guide hole 41a is also provided with a locking screw hole 41b that communicates with the outside; the adjustment part 4 includes a locking bolt 44, which is threadedly connected to the adjustment part 41 via the locking screw hole 41b and presses against the guide shaft 11.

[0058] In this embodiment, after the scraper 3 moves to the preset position, the locking bolt 44 is tightened, causing the locking bolt 44 to press against the guide shaft 11, preventing the adjusting member 41 from rotating unexpectedly relative to the guide shaft 11, and further improving stability. It should be noted that in one embodiment, the end of the locking bolt 44 pressing against the guide shaft 11 is provided with anti-slip rubber to increase the friction between the locking bolt 44 and the guide shaft 11, preventing the adjusting member 41 from rotating unexpectedly. In another embodiment, multiple locking screw holes 41b are spaced apart along the circumference of the adjusting member 41, and multiple locking bolts 44 are correspondingly provided. Each locking bolt 44 corresponds one-to-one with a locking screw hole 41b, and each locking bolt 44 is screwed into its corresponding locking screw hole 41b, further preventing the adjusting member 41 from rotating unexpectedly and improving stability.

[0059] In one embodiment, please refer to Figure 9 and Figure 10 One of the scraper 3 and the mounting part 1 is provided with a slide rail, and the other is provided with a slide groove for the slide rail to slide through. The slide rail and the slide groove extend along the movement direction of the scraper 3.

[0060] In this embodiment, the scraper 3 is guided to move by the cooperation of the slide rail and the slide groove, thereby improving the stability of the scraper 3's movement. Specifically, in this embodiment, the slide rail 32 is mounted on the scraper 3, and the slide groove 1a is formed on the guide shaft 11.

[0061] It should be noted that, in one embodiment, the guide shaft 11 includes a detachably connected fixed shaft 111 and a connecting shaft 112. The fixed shaft 111 is fixed to the mounting part 1 and has a receiving cavity 111a. The receiving cavity 111a is open at one end near the connecting shaft 112, and its side wall is provided with a sliding groove 1a. The connecting shaft 112 is connected to the driving part 2. The slide rail 32 is provided with a slot 32a at one end near the fixed shaft 111. The slot 32a is located in the receiving cavity 111a and is located on the side of the slide rail 32 near the opening of the receiving cavity 111a. The well-type tobacco seedling transplanter also includes a locking block 5. The locking block 5 is locked in the slot 32a and partially protrudes from the slot 32a, and can be blocked by the side wall of the receiving cavity 111a.

[0062] In this embodiment, when the scraper 3 is damaged, the connecting shaft 112 can be removed from the fixed shaft 111, and the locking block 5 in the slot 32a can be removed to slide the slide rail 32 out of the slot 1a, so that the scraper 3 is separated from the mounting part 1, which facilitates the repair and replacement of the scraper 3 and improves convenience.

[0063] It should be noted that the fixed shaft 111 and the connecting shaft 112 can be detachably connected by elastic snaps, threaded connections or bolts.

[0064] Specifically, in this embodiment, the connecting shaft 112 has a transition shaft 113 extending into the accommodating cavity 111a. The transition shaft 113 is provided with a connecting hole 113a, and the side wall of the accommodating cavity 111a is provided with a fixing screw hole 111c corresponding to the connecting hole 113a. The guide shaft 11 also includes a fixing bolt 116, which is sequentially inserted into the fixing screw hole 111c and the connecting hole 113a, so as to realize the detachable connection between the fixing shaft 111 and the connecting shaft 112.

[0065] It should be understood that in this embodiment, the transition shaft 113 and the slide rail 32 are spaced apart along the axial direction of the fixed shaft 111 to avoid the transition shaft 113 interfering with the movement of the slide rail 32.

[0066] In addition, to facilitate the alignment of the fixing screw hole 111c and the connecting hole 113a, the transition shaft 113 is provided with a polygonal positioning post 114 facing the fixing shaft 111, and the bottom wall of the receiving groove is provided with a polygonal positioning groove corresponding to the polygonal positioning post 114. Marking marks 115 are provided on the connecting shaft 112 and the fixing shaft 111 respectively, so as to facilitate the quick alignment of the fixing screw hole 111c and the connecting hole 113a.

[0067] In one embodiment, the scraper 3 has two blades 33, one of which extends along the rotation axis of the mounting portion 1 and is located on the outside of the scraper 3, and the other extends along the direction of movement of the scraper 3 and is located on the side of the scraper 3 close to the mounting portion 1.

[0068] In this embodiment, blades 33 are respectively provided on the outer and bottom sides of the scraper 3, so that the scraper 3 can simultaneously scrape the bottom and sidewall of the well, thereby improving the drilling efficiency of the scraper 3. It should be noted that, in order to further improve the stability of the scraper 3's movement, a guide groove 1b is provided on the mounting part 1 corresponding to the movement trajectory of the scraper 3. The blade 33 at the bottom of the scraper 3 is slidably disposed in the guide groove 1b, and the guide groove 1b is connected to the slide groove 1a.

[0069] It should be noted that the mounting part 1 can be a mounting base, a frame, or other forms.

[0070] In one embodiment, the outer diameter of the mounting portion 1 is gradually reduced in the direction away from the scraper 3.

[0071] In this embodiment, the outer diameter of the mounting part 1 is set as described above, so that the mounting part 1 is in the form of a drill bit, so that the mounting part 1 can quickly break the soil during rotation, thereby further improving the drilling efficiency of the device.

[0072] To better understand this utility model, the following is combined with... Figures 1 to 10 The technical solution of this utility model is described in detail below:

[0073] In this embodiment, when it is necessary to increase the inner diameter of the drilled well, the adjusting member 41 is rotated downwards, so that the pressing surface 411 of the adjusting member 41 drives the scraper 3 to move outwards from the mounting part 1. The scale line 117 on the guide shaft 11 is observed. When the scale line 117 indicated by the adjusting member 41 corresponds to the inner diameter of the required well, the locking bolt 44 on the adjusting member 41 is tightened. At this time, the distance between the scraper 3 and the rotation axis of the mounting part 1 is the inner diameter of the required well.

[0074] When it is necessary to reduce the inner diameter of the drilled well, first loosen the locking bolt 44, then rotate the adjusting part 41 upward. At this time, the scraper 3 can automatically retract under the influence of the elastic part 43. When the scale line 117 indicated by the adjusting part 41 is in place, tighten the locking bolt 44 again.

[0075] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
