DETAILED DESCRIPTION

[0017] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0018] It is understood that the terms "first", "second", etc. used in the present application may be used herein to describe various elements, but unless otherwise specified, these elements are not limited by these terms. These terms are only used to distinguish the first element from another element.

[0019] As Figure 1 , Figure 2 , Figure 5 and Figure 12 shown, in one embodiment, a plant pit-digging device for forestry is proposed. The device includes: Main body frame 1: including an installation fuselage 101 provided on the main body frame 1; Airbag mechanism 2: including an airbag tooth cylinder 201 installed inside the installation fuselage 101 for inflating and deflating, and further including a tooth shaft 202 rotatably installed on the inner wall of the installation fuselage 101 and cooperating with the airbag tooth cylinder 201. The airbag tooth cylinder 201 is fixedly installed on the inner wall of the spiral plate 203. It also includes a sliding shaft 205 fixedly installed on the inner wall of the installation fuselage 101. A wave cylinder 204 cooperating with the spiral plate 203 is slidably installed on the surface of the sliding shaft 205. The surface of the wave cylinder 204 is connected to the inner wall of the installation fuselage 101 through a tension spring 206. One end of the wave cylinder 204 is provided with an induction magnetic head. A circular magnetic head 208 cooperating with the induction magnetic head on the wave cylinder 204 is fixedly installed on the inner wall of the installation fuselage 101, and the induction thorn head and the circular magnetic head 208 have different magnetic properties. The circular magnetic head 208 is connected to an external controller. A limiting plate 207 for limiting the wave cylinder 204 is also installed inside the installation fuselage 101; Feedback mechanism 3: used to prevent the airbag tooth cylinder 201 from rotating when the driving mechanism 6 slips; Adjusting mechanism 4: used to adjust the moving distance of the driving mechanism 6; Excavating mechanism 7: used to complete the pit-digging operation on the ground.

[0020] In the actual application of the embodiment of the present invention, when performing a pit-digging operation on the ground, at this time, the driving mechanism 6 is adjusted to determine the spacing of the pits. As Figure 2 shown, after the first pit is excavated by the excavating mechanism 7 at this time, as Figure 5 shown, at this time, under the driving action of the driving mechanism 6, the device starts to move, so that the tooth shaft 202 rotates synchronously under the action of the driving mechanism 6. As Figure 12 shown, from Figure 12From the front view direction, due to the action of the feedback mechanism 3, the air bag gear cylinder 201 is meshed with the tooth shaft 202. At this time, the tooth shaft 202 drives the air bag gear cylinder 201 to rotate, and then drives the spiral plate 203 to rotate. The spiral plate 203 drives the wave cylinder 204 to move to the right through the spiral trajectory on its surface. It should be noted here that the spiral trajectory of the spiral plate 203 has not reached one circle after the wave cylinder 204 completes a wave of transverse movement. At this time, the spiral plate 203 is out of contact with the wave cylinder 204, thereby avoiding the interference of the spiral plate 203 when the wave cylinder 204 is out of the limit of the limit plate 207 and cannot be reset. At this time, the wave cylinder 204 moves one wave trajectory to the right for each rotation, and at the same time, the wave cylinder 204 cannot be reset under the limiting action of the limit plate 207. As the device moves, the wave cylinder 204 continues to move to the right. When it moves to multiple unit distances, When it reaches the set position, the limit plate 207 is disengaged from the limiting effect on the wave cylinder 204 under the external stimulation. At this time, the wave cylinder 204 is reset under the elastic potential energy of the tension spring 206, and the wave cylinder 204 contacts the circular magnetic head 208 again. At this time, the circular magnetic head 208 transmits a signal to the controller, so that the drive mechanism 6 stops moving, and the excavation mechanism 7 starts to run again to dig a pit. After the next pit digging is completed, the above operation is repeated to achieve the purpose of automatic fixed-distance digging. When the drive mechanism 6 slips during the movement of the driving device, the air bag tooth cylinder 201 is disengaged from the tooth shaft 202 through the action of the feedback mechanism 3. At this time, the rotation of the tooth shaft 202 will not drive the air bag tooth cylinder 201 to rotate, and will not drive the wave cylinder 204 to move to the right to consume the set value, thereby achieving the purpose of not affecting the final moving distance when slipping and ensuring the stability of the moving distance.

[0021] like Figure 7 , Figure 8 , Figure 11 and Figure 12As shown, as a preferred embodiment of the present invention, the feedback mechanism 3 includes a feedback runner 301 rotatably mounted on the installation fuselage 101. A plurality of anti-slip rods 302 are fixedly mounted on the surface of the feedback runner 301. A transmission belt group 303 is coaxially and fixedly mounted on the surface of the feedback runner 301. The other end of the transmission belt group 303 is rotatably connected to the inner wall of the installation fuselage 101. A plurality of wire columns 304 are fixedly mounted on the surface of the other end of the transmission belt group 303. The wire columns 304 are located between the relative projection areas of the first permanent magnet 310 and the second permanent magnet 311. The first permanent magnet 310 and the second permanent magnet 311 have different magnetic properties. The other ends of the plurality of wire columns 304 are all connected to the energized electromagnet 305. The energized electromagnet 305 is connected to the connecting magnet 307 through an elastic airbag 306. The connecting magnet 307 is slidably connected to the air delivery pipe 308. The air delivery pipe 308 is fixedly mounted inside the installation fuselage 101. The other end of the air delivery pipe 308 is connected to the fixed airway block 309. An annular groove is formed inside the fixed airway block 309. And the elastic airbag 306, the inside of the air delivery pipe 308, the annular groove inside the fixed airway block 309 and the inside of the airbag tooth cylinder 201 are sequentially communicated. The first permanent magnet 310 and the second permanent magnet 311 are both fixedly mounted inside the installation fuselage 101.

[0022] In the actual application of the embodiment of the present invention, when the device is driven to move under the driving action of the driving mechanism 6, at this time, the feedback runner 301 is driven to rotate by the contact between the anti-slip rod 302 and the ground, as Figure 12 shown. The rotation of the feedback runner 301 drives the wire columns 304 to rotate through the transmission belt group 303. At this time, since the wire columns 304 are located between the first permanent magnet 310 and the second permanent magnet 311, the rotation of the wire columns 304 makes the inside of the wire columns 304 charged, and then makes the energized electromagnet 305 generate magnetism. It should be noted here that an external battery can be added to supply power to the inside of the wire columns 304 when the wire columns 304 rotate, so as to ensure the stability of the energized electromagnet 305 being magnetized. Under the magnetic attraction, the connecting magnet 307 is driven to move towards the direction of the energized electromagnet 305. At this time, the elastic airbag 306 is compressed and the air inside is delivered to the airbag tooth cylinder 201 through the air delivery pipe 308 and the fixed airway block 309. After the airbag tooth cylinder 201 is inflated, it cooperates with the tooth shaft 202. At this time, the rotation of the tooth shaft 202 drives the airbag tooth cylinder 201 to rotate to achieve the purpose of fixed-distance movement. When the driving mechanism 6 slips, at this time, since the position of the device does not change, the wire columns 304 will not rotate, making the energized electromagnet 305 lose magnetism. At this time, under the elastic action of the elastic airbag 306 itself, the connecting magnet 307 is driven to reset. At this time, the elastic airbag 306 resets and sucks back the air in the airbag tooth cylinder 201. At this time, the airbag tooth cylinder 201 is separated from the tooth shaft 202, thus avoiding the influence of slipping on the movement distance of the device.

[0023] like Figure 12 and Figure 13 As shown, as another preferred embodiment of the present invention, the adjustment mechanism 4 includes a driver 401 installed inside the installation body 101, the output end of the driver 401 is connected to the adjustment card block 402, the driver 401 is fixedly installed on the moving plate frame 406, and the adjustment card block 402 is slidably connected to the moving plate frame 406, the inner wall of the moving plate frame 406 is slidably installed with a follower slide 411, the surface of the follower slide 411 is fixedly installed with an adjustment magnet 403, the surface of the follower slide 411 is slidably connected with a follower magnetic plate 405, the adjustment magnet 403 is connected to the follower magnetic plate 405 through a connecting spring 404, and the magnetism of the adjustment magnet 403 after power is turned on is connected to the follower magnetic plate 405. The plate 405 is different. The follow-up slide plate 411 is connected to the inner wall of the moving plate frame 406 through the compression spring 410. The moving plate frame 406 and the adjusting screw 407 form a spiral pair transmission. The other end of the adjusting screw 407 is connected to the adjusting motor. The adjusting motor is fixedly installed on the inner wall of the mounting body 101. The moving plate frame 406 is slidably connected to the inner wall of the mounting body 101. The inner wall of the mounting body 101 is also fixedly installed with an adjusting card plate 408 that matches the adjusting card block 402. The rectangular slots on the adjusting card plate 408 correspond one-to-one to the wave protrusions on the wave cylinder 204. The surface of the wave cylinder 204 is fixedly installed with a ratchet plate 409 that matches the follow-up magnetic plate 405.

[0024] In actual application of the embodiment of the present invention, when the device is moved, the parameters of the unit distance are input in advance by a person, such as Figure 12 and Figure 13 As shown, from Figure 13 408, and the follower magnetic plate 405 and the ratchet plate 409 are all in a non-matching state. At this time, the adjusting screw 407 rotates under the operation of the adjusting motor, driving the moving plate frame 406 to move to the left, and the synchronous adjusting block 402 moves to the set rectangular slot position of the adjusting card plate 408. At this time, the adjusting motor stops running, and the driver 401 runs to make the adjusting block 402 snap into the slot position of the adjusting card plate 408, and at the same time, the adjusting magnet 403 When the power is turned off, the magnetism is lost, so that the follower magnetic plate 405 is stuck in the ratchet plate 409. As the wave cylinder 204 moves to the right, the ratchet plate 409 is driven to move to the right synchronously, and then the follower magnetic plate 405 is driven to move to the right synchronously. When the follower magnetic plate 405 moves to the initial position, it triggers external movement to drive the limit plate 207 to rotate. At this time, the limit plate 207 no longer restricts the wave cylinder 204, so that the wave cylinder 204 resets the trigger signal to stop the driving mechanism 6, thereby achieving the purpose of automatic fixed-distance movement.

[0025] like Figure 6 ,Figure 10 and Figure 13 As shown, as another preferred embodiment of the present invention, the device also includes a toggle mechanism 5, which includes an L-shaped rack 501 fixedly mounted on the surface of the follower slide 411, and also includes a follower gear 502 rotatably connected to the inner wall of the mounting body 101 and matched with the L-shaped rack 501, and the surface of the follower gear 502 is connected to the inner wall of the mounting body 101 through a torsion spring 503.

[0026] In practical application of the embodiment of the present invention, when the follower magnetic plate 405 moves to the right, Figure 13 As shown, at this time, the follower magnetic plate 405 drives the L-shaped rack 501 to move to the right synchronously. When the follower magnetic plate 405 moves to the starting position, as shown in FIG. Figure 10 As shown, at this time, the L-shaped rack 501 is meshed with the follower gear 502, and the movement of the L-shaped rack 501 drives the follower gear 502 to rotate, and then drives the limit plate 207 to rotate synchronously, so that the wave cylinder 204 is no longer limited by the limit plate 207, and the wave cylinder 204 resets the trigger signal, so that the drive mechanism 6 stops driving, thereby achieving the purpose of automatic feedback to stop the movement and ensuring the stability of the movement distance.

[0027] like Figure 9 As shown, as another preferred embodiment of the present invention, the driving mechanism 6 includes a driving motor 601 fixedly mounted on the inner wall of the mounting body 101, a bevel gear set 602 is fixedly mounted on the output end of the driving motor 601, the other end of the bevel gear set 602 is coaxially fixedly connected to the gear shaft 202, a driving belt set 603 is coaxially fixedly mounted on the surface of the gear shaft 202, and the other end of the driving belt set 603 is coaxially fixedly connected to the driving wheel 604.

[0028] In practical application of the embodiment of the present invention, when the device is moved, such as Figure 9 As shown, at this time, the driving motor 601 starts to run, and the operation of the driving motor 601 drives the bevel gear set 602 to rotate. The rotation of the bevel gear set 602 drives the driving wheel 604 to rotate through the tooth shaft 202 and the driving belt set 603. One rotation of the driving wheel 604 is a wave trajectory of the wave cylinder 204, so that the device starts to move, achieving the purpose of automatic drive movement.

[0029] like Figure 2 and Figure 4As shown in the figure, as another preferred embodiment of the present invention, the excavation mechanism 7 includes two feeding motors 703 fixedly installed on the inner wall of the installation fuselage 101. The output end of each feeding motor 703 is fixedly installed with a rotating lead screw 704. Both rotating lead screws 704 form a helical pair drive with a lead screw slide plate 705. The surface of the lead screw slide plate 705 is fixedly installed with an excavation motor 701. The output end of the excavation motor 701 is fixedly installed with an excavation auger 702. The surface of the lead screw slide plate 705 is penetrated by a conveying cylinder 706 and is slidably connected to the conveying cylinder 706. The conveying cylinder 706 is connected to the lead screw slide plate 705 through a return spring 707. The excavation auger 702 is installed in the internal passage of the conveying cylinder 706. The surface of the conveying cylinder 706 is fixedly installed with a blanking cylinder 708. A collection box 709 is also fixedly installed inside the installation fuselage 101.

[0030] In the actual application of the embodiment of the present invention, when the fixed-distance movement is completed, as Figure 4 shown, at this time, the feeding motor 703 starts to operate. The feeding motor 703 drives the lead screw slide plate 705 to move vertically downward through the helical pair drive, and then drives the excavation auger 702 and the conveying cylinder 706 to move downward synchronously. When the conveying cylinder 706 touches the ground, at this time, the excavation motor 701 starts to operate, driving the excavation auger 702 to rotate. At this time, as the feeding motor 703 continues to operate, it drives the excavation auger 702 to dig the soil downward. The dug soil moves upward through the conveyance of the excavation auger 702 and the limiting effect of the conveying cylinder 706. As Figure 2 shown, and then it falls into the collection box 709 through the blanking cylinder 708, so as to achieve the functions of automatically digging pits and collecting soil.

[0031] As Figure 3 shown, as another preferred embodiment of the present invention, the teeth on the airbag tooth cylinder 201 and the tooth shaft 202 are both made of hard rubber.

[0032] In the actual application of the embodiment of the present invention, as Figure 3 shown, through the rubber teeth provided on the airbag tooth cylinder 201 and the tooth shaft 202, the friction of extrusion is reduced during the cooperative rotation, thereby improving the service life of the device.

[0033] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.
