[0029] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.

[0030] See also Figures 1 to 4 The present invention provides an automatic tree planting device, comprising: a bottom plate assembly 1, a conveying assembly 2 for conveying materials such as saplings, and a clamping assembly 3 for automatically clamping materials such as saplings, the bottom plate assembly 1 comprises a bottom plate 11, the conveying assembly 2 comprises a conveying unit 21 and at least one mounting block 22 for placing materials, the conveying unit 21 is connected to the bottom plate 11, the mounting block 22 is detachably connected to the conveying unit 21, and is used for cyclically conveying materials, the clamping assembly 3 comprises a clamping member 31, a translation member 32 and a lifting member 33, the clamping member 31 and the conveying unit 21 are mutually connected The clamping member 31 is provided with a clamping gap of adjustable size, the translation member 32 has a first fixed end and a first movable end, the first fixed end is provided on the bottom plate 11, the first movable end is connected to the clamping member 31, and is used to drive the clamping member 31 to translate in a direction close to or away from the conveying unit 21, the lifting member 33 includes a second fixed end and a second movable end, the second fixed end is connected to the bottom plate 11, and the second movable end is connected to the first fixed end, and is used to drive the translation member 32 and the clamping member 31 to rise and fall, so as to cooperate with the clamping member 31 to clamp and release the material on the mounting block 22.

[0031] In the present device, a conveying unit 21 for cyclically conveying materials such as seedlings along a specified path is connected to a base plate 11, and a clamping member 31 is connected to the base plate 11 via a first movable end of a translation member 32, so that the clamping member 31 can translate toward or away from the conveying unit 21, and a first fixed end of the translation member 32 is connected to the base plate 11 via a second movable end of a lifting member 33, so that the translation member 32 and the clamping member 31 can be lifted and lowered, and the movement of the translation member 32 and the lifting member 33 cooperates with the clamping member 31 to complete automatic clamping of materials such as seedlings on the conveying unit 21.

[0032] It can be understood that compared with the prior art, the conveying unit 21 is first used to cyclically convey multiple materials such as seedlings along a designated track, and then the clamping member 31 is used to automatically clamp the seedlings and other materials placed on the conveying unit 21 through the movement of the translation member 32 and the lifting member 33. It can be used to solve the problem of low automation of the tree planting machine in the prior art, which requires manual cooperation in feeding to put the seedlings to be planted into the buckle of the planting mechanism and be clamped by the manipulator.

[0033] Furthermore, the material in the device is a seedling of a species such as Populus euphratica, which has few branches and a long trunk, and can be easily clamped by the clamping member 31, which will not be elaborated here.

[0034] like Figure 2 , Figure 3 and Figure 5 As shown, the device further includes a rotary disk 4 , a drilling assembly 5 connected to the rotary disk 4 , and a soil covering assembly 6 connected to the base plate 11 .

[0035] Among them, the base plate 11 is also provided with a first through hole 111, which is spaced apart from the clamping assembly 3. The turntable 4 is connected to the base plate 11 and rotates around its axis, and is provided with a second through hole 112 for allowing materials to pass through. The second through hole 112 can be connected to the first through hole 111 after the turntable 4 rotates. The support disc 311 is arranged relative to the second through hole 112, and is connected to the turntable 4 via the translation member 32 and the lifting member 33.

[0036] It can be understood that the first through hole 111 serves as a planting channel for planting materials such as seedlings, and is spaced apart from the conveying component 2 at the end and the middle of one end of the bottom plate 11, that is, under the cooperation of the translation member 32 and the lifting member 33, after the seedlings and other materials are taken from the middle conveying component 2, the rotating disk 4 rotates so that the clamping member 31 is set relative to the first through hole 111, and again under the cooperation of the translation member 32 and the lifting member 33, the seedlings to be planted are inserted into the soil to be planted through the first through hole 111.

[0037] As an implementation mode, the turntable 4 is also provided with a third through hole 113, and the third through hole 113 can be connected with the first through hole 111 after rotating with the rotating disk 3131. The drilling assembly 5 is arranged relative to the third through hole 113 and connected to the turntable 4. The drilling assembly 5 can be extended and retracted along the axial direction of the third through hole 113 and pass through the first through hole 111 for breaking the ground and digging a hole.

[0038] It can be understood that the drilling assembly 5 and the clamping assembly 3 are both connected to the base plate 11 through the turntable 4, and a third through hole 113 is opened on the turntable 4 relative to the first through hole 111. The drill bit on the drilling assembly 5 passes through the third through hole 113 and the second through hole 112 in turn and is inserted into the soil to break the ground and dig a hole.

[0039] Furthermore, by controlling the rotation of the turntable 4, the first through hole 111 is connected to the second through hole 112 or the third through hole 113 respectively, and the clamping assembly 3 or the drilling assembly 5 is arranged above the first through hole 111. In this way, drilling and tree planting can be achieved through only one channel, without the need to move the planting device, thereby avoiding position deviation caused by movement.

[0040] Furthermore, the drilling assembly 5 here is a drill bit that can be extended and retracted in the vertical direction and has a soil breaking function, etc. This is a conventional setting well known to those skilled in the art and will not be elaborated on here.

[0041] As another embodiment, the covering assembly 6 includes two covering blocks 61, a hinge 62 and a driving member 63. The two covering blocks 61 are symmetrically distributed on both sides of the first through hole 111. The hinge 62 is connected to the two covering blocks 61. The driving member 63 has a fixed end and a movable end. The fixed end of the driving member 63 is connected to the base plate 11, and the movable end is connected to the hinge 62, which is used to drive the hinge 62 to drive the two covering blocks 61 to move closer to or away from each other.

[0042] It can be understood that the two covering blocks 61 are symmetrically arranged on both sides of the first through hole 111, and the movement of the driving member 63 is transmitted to the two covering blocks 61 through the transmission of the hinge part, so that the covering blocks 61 move closer to each other. After the sapling is inserted into the pit, the two covering blocks 61 form a force similar to that of a person's palms, covering the dug soil on the sapling.

[0043] Furthermore, if Figure 2 and Figure 5 As shown, the soil covering component 6 in the present device is designed to be installed at the rear lower part of the vehicle body and is arranged relative to the first through hole 111. It includes a soil covering rod of a scissor mechanism, a positioning ring optical axis, a track for limiting sliding and at least one connecting rod, and a pushing device composed of a push rod motor mounting bracket, a push rod motor, and a connecting piece between the motor rod and the shaft. When the output shaft of the push rod motor extends outward, the optical axis is pushed to roll in the track for limiting sliding, and the connecting rod connected to the optical axis rotates a certain angle accordingly, thereby driving the soil covering rod to rotate a certain angle, so that the soil covering rod changes from an open state to a closed state. This can also be achieved by two relatively arranged linear driving members connected to the soil covering block 61, and driving the two soil covering blocks 61 to move closer to each other. No further elaboration is given here.

[0044] Furthermore, the base plate assembly 1 in the present device should also include a moving part 12 for realizing the movement of the base plate 11, an irrigation part 13 for watering the seedlings after planting, and a driving part for driving the turntable 4 to rotate, etc. Here, the moving part 12, the irrigation part 13 and the driving part are conventional settings well known to those skilled in the art and will not be elaborated on here.

[0045] like Figure 4 As shown, a material trough is provided on the bottom plate 11 , and the conveying unit 21 includes a circulating track 211 , at least one sliding block 212 , two gears 213 , a transmission chain 214 and a first motor 215 , and two guide wheels 216 connected to the sliding block 212 .

[0046] Among them, the circulating track 211 is in the shape of an elliptical ring and is connected to the inner wall of the material trough. The sliding block 212 is arranged on the circulating track 211, and the sliding block 212 is arranged one-to-one with the mounting block 22 and is connected to the mounting block 22. The two gears 213 are arranged at intervals from each other and rotate around their own axes and are built into the material trough. The transmission chain 214 is meshed with the two gears 213 and is transmission-connected to the two gears 213. The transmission chain 214 is detachably connected to the sliding block 212. The first motor 215 is fixedly connected to the base plate 11, and its output shaft is connected to a gear 213, which is used to drive the sliding block 212 to move along the guide circulation of the circulating track 211 along the transmission chain 214.

[0047] It can be understood that the cooperation of the two gears 213 , the transmission chain 214 and the first motor 215 is used to drive the sliding block 212 and the mounting block 22 to convey materials such as saplings along the guided circulation of the circulation track 211 .

[0048] Furthermore, the mounting block 22 here is detachably connected to the sliding block 212, and the mounting block 22 is provided with at least one second clamping groove for placing materials relative to the clamping gap. The at least one second clamping groove is point-symmetrically distributed along the center of the mounting block 22, which can be suitable for clamping one, two or three seedlings at the same time.

[0049] As an implementation method, the cross-section of the circulating track 211 is in the shape of an "I", and two first guide grooves are formed along the two back sides of the circulating track 211, and the guide wheels 216 are arranged one by one corresponding to the first guide grooves. The peripheral walls of the two guide wheels 216 are respectively slidably embedded in the first guide grooves, and the center rotations of the two guide wheels 216 are connected to the sliding block 212.

[0050] It can be understood that the cooperation between the guide wheel 216 and the guide groove plays a connecting and guiding role in the sliding of the sliding block 212 along the circulating track 211. At the same time, the guide wheel 216 is embedded in the guide groove to prevent the sliding block 212 from separating from or falling off the circulating track during the sliding process.

[0051] like Figures 6 to 9 As shown, the clamping member 31 includes a supporting disc 311, at least three first clamping blocks 312 and a driving portion 313, connected to the supporting disc 311 and at least three guide rods 314 and at least three connecting blocks 315, and at least one second clamping block 316 connected to the first clamping block 312.

[0052] Among them, the support disc 311 is provided with at least three slide grooves, at least three slide grooves are arranged along the radial direction of the support disc 311, and are distributed in a point-symmetrical manner along the center of the support disc 311. The first clamping block 312 is arranged in a one-to-one correspondence with the slide groove, and is connected to the support disc 311 along the guide sliding of the slide groove. The opposite sides of the first clamping block 312 are respectively provided with first clamping grooves, and at least three first clamping grooves are enclosed to form a clamping gap. The driving part 313 is connected to the three first clamping blocks 312, and is used to drive the three first clamping blocks 312 to approach or move away from each other along the radial direction of the support disc 311 to clamp or release the material.

[0053] It can be understood that at least three first clamping blocks 312 are distributed point-symmetrically along the center of the supporting disk 311. Driven by the driving part 313, the three first clamping blocks 312 simultaneously approach or move away from each other along the guide of the slide slot to clamp materials such as saplings.

[0054] As an embodiment, the support disc 311 is also provided with a receiving groove, which is connected to at least three slide grooves. The guide rod 314 is arranged radially relative to the slide groove along the support disc 311, and one end of the guide rod 314 is connected to the circumferential inner wall of the receiving groove. The connecting block 315 is arranged one by one with the first clamping block 312. The connecting block 315 is in an inverted "T" shape and has a large diameter section and a small diameter section. The large diameter section of the connecting block 315 is connected to the first clamping block 312, and the small diameter section of the connecting block 315 is slidably inserted in the slide groove and slidably sleeved on the guide rod 314.

[0055] It can be understood that the cooperation between the guide rod 314 and the connecting block 315 plays a connecting and guiding role in the sliding of the clamping block.

[0056] As a preferred implementation method, Figure 6 and Figure 8 As shown, at least one second clamping block 316 is arranged at intervals along the height direction of the first clamping block 312 and connected to two opposite sides of the clamping groove, and the second clamping blocks 316 on two adjacent first clamping blocks 312 are arranged alternately.

[0057] It can be understood that at least one second clamping block 316 is arranged at intervals and connected to the first clamping block 312, and the second clamping blocks 316 on two adjacent first clamping blocks 312 are staggered with each other, so that the two adjacent first clamping blocks 312 can overlap with each other, thereby having a larger stroke to clamp materials such as seedlings located on the center line of the support disk 311, and can complete the grasping and planting of one, two, or three seedlings and other materials according to planting needs.

[0058] like Figures 6 to 9As shown, the driving part 313 includes a rotating disk 3131, at least three sliding rods 3132 and a second motor 3133. The rotating disk 3131 is rotatably built in the accommodating groove, and the rotating disk 3131 is provided with at least three second guide grooves, the second guide grooves are arc-shaped, and the at least three second guide grooves are point-symmetrically distributed along the center of the rotating disk 3131. The sliding rods 3132 are arranged one-to-one with the second guide grooves, and one end of the sliding rod 3132 is slidably connected to the second guide groove, and the other end is connected to the small diameter section of the connecting block 315. The output shaft of the second motor 3133 is connected to the rotating disk 3131, and is used to drive the rotating disk 3131 to rotate around its rotation axis in a clockwise direction or counterclockwise direction.

[0059] It can be understood that during the rotation of the rotating disk 3131 , the sliding rod 3132 slides relative to the rotating disk 3131 along the guide of the second guide groove, so that at least three first clamping blocks 312 move synchronously.

[0060] Furthermore, in the present device, at least one steel ball is disposed between the inner wall of the receiving groove and the rotating disk 3131 to reduce the friction between the rotating disk 3131 and the receiving groove during the rotation of the rotating disk 3131, which will not be elaborated herein.

[0061] As an implementation mode, the translation member 32 in the device is a linear motion mechanism formed by a pulley, a belt and a sliding block 212 to achieve translation in the horizontal direction, and the lifting member 33 is a ball screw nut pair structure composed of a screw, a nut and a motor, which can achieve lifting and lowering in the vertical direction. Here, the translation member 32 and the lifting member 33 can also be replaced by hydraulic cylinders, push rod motors and cylinders, etc. This is a conventional setting known to technical personnel in this field and will not be elaborated here.

[0062] The specific working process of the present invention is that the conveying unit 21 for cyclically conveying materials such as seedlings along a designated path is connected to the bottom plate 11, the clamping member 31 is connected to the bottom plate 11 via the first movable end of the translation member 32, so that the clamping member 31 can be translated close to or away from the conveying unit 21, and the first fixed end of the translation member 32 is connected to the bottom plate 11 via the second movable end of the lifting member 33, so that the translation member 32 and the clamping member 31 can be lifted and lowered, and the movement of the translation member 32 and the lifting member 33 cooperates with the clamping member 31 to automatically clamp the seedlings and other materials on the conveying unit 21. Compared with the prior art, the conveying unit 21 is first used to cyclically convey multiple materials such as seedlings along a designated track, and then the movement of the translation member 32 and the lifting member 33 cooperates with the clamping member 31 to automatically clamp the seedlings and other materials placed on the conveying unit 21. The invention can be used to solve the problem in the prior art that the tree planting machine has a low degree of automation because manual feeding is required to put the seedlings to be planted into the buckles of the planting mechanism and clamp them by a robot.

[0063] When the device is in use, after the base plate 11 is moved to the designated planting area, the rotary disk 4 first rotates to connect the third through hole 113 with the first through hole 111, and then the drilling assembly 5 lifts and lowers the drill bit, and recovers it after completing the soil-breaking and digging work. Then the translation member 32 and the lifting member 33 cooperate to move the first clamping block 312 and the second clamping block 316 close to the circulating track 211, and drive at least three first clamping blocks 312 to approach synchronously under the drive of the second motor 3133 to clamp the sapling, and then the clamping member 31 holding the sapling is driven by the translation member 32 to move directly above the second through hole 112, and the rotary disk 4 rotates to connect the second through hole 112 with the first through hole 111, and then the lifting member 33 lifts and lowers the sapling, and recovers it after completing the planting work. Finally, the driving member 63 drives the two covering blocks 61 to approach each other through the hinge 62, suddenly covers the sapling, and irrigates it.

[0064] Furthermore, the user can reasonably change the number of seedlings placed on the mounting block 22 according to the soil conditions in the planting area. After completing one material extraction, the first motor 215 drives the transmission chain 214 and the gear 213 to move, so that the next mounting block 22 with the seedlings placed thereon moves to below the movement trajectory of the clamping member 31, waiting for the next material grabbing, thereby realizing automatic drilling, seedling transportation, seedling extraction, seedling planting, soil covering and irrigation operations for seedlings and other materials, thereby improving the automation of planting.

[0065] The above structure can be used to solve the problem in the prior art that the tree planting machine has a low degree of automation because manual feeding is required to place the seedlings to be planted into the buckles of the planting mechanism and clamped by the robot.

[0066] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
