Description

Auxiliary special equipment for garden engineering planting

Technical Field

Background

In the traditional large-batch tree planting, all tree pits are dug out by a digging machine or manually, and then the trees are transplanted into the tree pits uniformly. Finally, soil is backfilled into the tree pit through a digging machine or a manual mode so as to complete planting of the tree. When soil is backfilled into the tree pit by using a digging machine or manually, in order to effectively backfill the annular region around the trunk in the tree pit, the digging machine must backfill the tree pit around the tree movement, so that the digging machine consumes more energy and has lower backfilling efficiency due to more frequent movement of the digging machine around the trunk caused by backfilling the annular region around the trunk. And the artificial backfilling mode has lower efficiency in large-batch planting.

Aiming at the problems existing in the traditional backfilling mode in the large-batch tree planting, it is necessary to design a special planting auxiliary device suitable for large-batch planting so as to improve the planting backfilling efficiency.

The invention designs an auxiliary special device for garden engineering planting, which solves the problems.

The vehicle body 1 drives the tree planting machine to horizontally move towards the trees planted in the tree pits. Meanwhile, the hydraulic column A7 is controlled to shrink through the control system according to the height of soil accumulated around the tree pit, the hydraulic column A7 drives the U-shaped seat A5 to vertically move upwards for a certain height in the guide seat A3, and the U-shaped seat A5 drives the two guide seats B13 to synchronously vertically move upwards through the swing rod 8 and the U-shaped seat B11 which are hinged with the U-shaped seat A5. The two guides B13 move the two sector plates a26 and all the parts mounted thereon in synchronism. Meanwhile, the two guide blocks a6 moving synchronously with the U-shaped seat a5 drive the two hydraulic columns C44 to move vertically and upwardly synchronously through the two rotating columns 57. So that the lower ends of a plurality of arc plates A39 installed below the two sector plates A26 are higher than the top end of the soil heap.

If the tree pit is located in a hillock or a depression with high terrain, when the front wheels of the vehicle body 1 reach the hillock or the depression, the vehicle body 1 drives the vehicle body 1 to generate the condition that the front end of the vehicle body is tilted upwards or downwards. At this time, as the vehicle body 1 continues to drive the present invention to approach the tree pit and simultaneously control the hydraulic column B9 to extend or shorten, the extended hydraulic column B9 drives the swing rod 8 to swing around the hinge point of the swing rod and the U-shaped seat a5, the swing rod 8 drives the two guide seats B13 and the two sector plates a26 installed at one end of the swing rod to tilt up or tilt down and keep a certain height distance from the soil heap, and the two guide seats B13 and the two sector plates a26 keep a vertical relation with the trunk, so that the soil heap around the tree pit can be effectively backfilled by the plurality of arc plates a39 installed on the two subsequent sector plates a 26. Meanwhile, the two guide seats B13 respectively drive the rotating column 57 on the same side to rotate adaptively relative to the U-shaped seat a5 through the corresponding hydraulic columns B9.

When the trunk is located at the central position between the two guide seats B13, the soil accumulated around the tree pit is just positioned in the range of the vortex lines of the arc plates A39. At this time, the vehicle body 1 controls the two hydraulic columns C44 to extend, the two hydraulic columns C44 drive the two guide seats B13 to close around the pin a20, and simultaneously, the two guide seats B13 drive the two sector plates a26 to close around the pin B38. The two guide shoes B13 form a complete ring, the two sector plates a26 form a complete ring plate, and the tree is located at the center of the ring plate formed by the two sector plates a 26.

At this moment, the supporting mechanisms 45 symmetrically installed on the two guide seats B13 form package clamping on the trunk at the center, in the clamping process, the telescopic rods 46 in the two clamping mechanisms contract under the action of the trunk, the springs C55 in the telescopic rods 46 are further compressed for storing energy, and the arc plates B53 in the two supporting mechanisms 45 can generate self-adaptive swing around the respective pin shafts C52 under the action of the trunk so as to form effective clamping packages on the trunk and prevent the trunk from toppling over in the tree pit backfilling process. With the swing of the arc plate B53 relative to the corresponding expansion plate, the scroll spring 56 nested on the pin C52 deforms and stores energy,

when the two guide seats B13 are fully closed, the two sector plates a26 are just fully closed. The limiting groove A19 of the locking block 18 arranged on one guide seat B13 is just opposite to the sliding groove A16 on the other guide seat B13. The semicircular cylinders mounted on the two sector plates a26 are merged into one complete circular cylinder, the two semicircular ring gears 34 are merged into one complete ring gear 34, and the two trapezoidal guide bars 31 mounted on the two sector plates a26 are merged into one complete annular trapezoidal guide bar 31. The semi-annular grooves A14 in the two guide seats B13 merge into a complete annular groove A14. The two semi-circular trapezoidal guide grooves 15 are combined into a complete circular trapezoidal guide groove 15. At this point, the tree is located exactly at the center of several arc plates a39 arranged along a spiral line concentric with sector plate a 26. The two hydraulic columns B9 still keep pushing the two guide seats B13 so that the two guide seats B13 keep the closed state. The control system then controls the hydraulic column A7 to extend and drive the U-shaped seat A5 to move vertically downwards. The U-shaped seat A5 drives the two guide seats B13, the two sector plates A26 and all the components mounted on the sector plates A26 to synchronously move vertically and downwards through the swing rod 8 and the U-shaped seat B11. When the lower ends of the arc plates A39 mounted on the lower surfaces of the two sector plates A26 are inserted into the soil, the electric drive module 37 is controlled to operate, and the electric drive module 37 drives the two combined sector plates A26 to rotate in the groove A14 relative to the guide seat B13 through the gear A36, the gear B35, the gear ring 34 and the cylinder. The two fan-shaped plates A26 drive the arc plates to rotate synchronously, and the rotating direction is the same as the rotating direction of the arc plates A39 around the outward vortex from the center.

With the rotation of the two fan-shaped plates A26, the side wall inclined surface of the unlocking groove 30 on the fan-shaped plate A26 and the side wall inclined surface of the unlocking opening 32 on the trapezoid guide bar 31 interact with one end of the limiting block 21, and the limiting block 21 moves towards the limiting groove A19 on the locking piece 18 under the action of the side wall inclined surfaces of the unlocking groove 30 and the unlocking opening 32. When one end of the limiting block 21 moves to the outside of the unlocking groove 30 and the unlocking opening 32 and contacts with the outer edge surface of the sector plate A26, the other end of the limiting block 21 just completely enters the limiting groove A19 on the locking block 18 and completes the locking of the two closed guide seats B13, and the limiting block 21 keeps entering the limiting groove A19 under the action of the outer edge surface of the sector plate A26, so that the two guide seats B13 cannot be separated and disengaged in the following operation. At this time, the stopper 21 further compresses the spring a22 through the compression spring ring 25, and since the one-way damping lever 24 does not exert a damping action at this time, the stopper 21 rapidly pulls the one-way damping lever 24 to extend through the connecting rod 23.

After the limiting block 21 locks the closed state of the two guide seats B13, the control system controls the two hydraulic columns C44 to stop acting on the two guide seats B13, so that the energy consumption of the hydraulic columns C44 for pushing the two guide seats B13 to keep the closed state is reduced. When the unlocking groove 30 of the rotating sector plate a26 is repeatedly opposed to the stopper 21, the one-way damping lever 24 exerts a damping action, so that the stopper 21 loses the support of the outer edge surface of the sector plate a26, but the stopper 21 is not reset by the reset action of the spring a22 in a short time due to the damping action of the one-way damping lever 24. When the limiting block 21 is not reset in time, the unlocking groove 30 and the unlocking notch 32 pass through quickly, the outer edge surface of the sector plate A26 contacts with one end of the limiting block 21 again and forms the reset limitation of the limiting block 21, so that the limiting block 21 always locks the closed state of the two guide seats B13 in the process that the two combined sector plates A26 rotate relative to the two combined guide seats B13, and the two combined guide seats B13 are ensured to provide a permanent and stable rotating guide rail for the rotating sector plate A26.

When the arc plates A39 rotate along with the two combined fan-shaped plates A26, the rotation direction of the fan-shaped plates A26 is the same as the outward vortex direction of the vortex line of the arc plates A39 from the center, so the arc plates A39 arranged in the vortex line move the soil within the range of the arc plates A39 to the center position direction of the trunk in the tree pit under the drive of the two rotating fan-shaped plates A26, and the soil falls into the tree pit and fills the tree pit gradually in the process of moving to the center of the trunk. The arc plate A39 is limited by the limiting slide block 42, so the arc plate A39 can not slide towards the center under the reaction of the soil, and the moving efficiency of the arc plate A39 for pushing the soil is improved.

When the tree pit is backfilled with small stones, the two fan-shaped plates B43 are taken down from the fan-shaped plate A26, and the limit of the arc plate A39 sliding along the vortex line is relieved by the limit sliding block 42. When the arc plates A39 rotating along with the fan-shaped plates A26 push the small stones to move into the tree pit, the reaction of the small stones on the arc plates A39 enables the arc plates A39 to slide along the vortex lines in which the arc plates A39 are located towards the center in a certain range, and the corresponding springs B41 are stretched to store energy. The arc plate A39 forms the reciprocating motion of small-range under the continuous effect with the cobble and the effect that resets of spring B41, forms certain degree buffering to the impact wear that the cobble led to the fact arc plate A39 to reduce the wearing and impact of cobble to arc plate A39, prolong arc plate A39's life. After the backfill of the small stones is finished, the arc plates A39 are completely reset relative to the sector plates A26 under the reset action of the corresponding springs B41 respectively.

After the backfilling of the tree pit is finished, the control system continuously controls the electric drive module 37 to operate, when the central axis of the pin shaft B38 between the two fan-shaped blocks A is coincident with the central axis of the pin shaft A20 between the two guide seats B13, the control system controls the electric drive module 37 to stop operating, the two fan-shaped plates A26 stop rotating, and the initial relative state between the two fan-shaped plates A26 and the corresponding guide seats B13 is recovered. The unlocking groove 30 on the sector plate A26 and the unlocking opening 32 on the trapezoid guide bar 31 are right opposite to the limiting block 21, and the one-way damping rod 24 plays a damping role at the moment, so the limiting block 21 slowly moves towards the unlocking opening 32 and the unlocking groove 30 under the combined action of the spring A22 which is further compressed and stored with energy and the one-way damping rod 24, finally enters the unlocking groove 30 to be separated from the limiting groove A19, and the unlocking of the merging state of the two guide seats B13 is completed.

Then, the control system controls the two hydraulic columns C44 to perform contraction movement, and the two hydraulic columns C44 simultaneously pull the two guide seats B13 to swing and expand in two sides around the pin shaft A20. The two guide seats B13 drive the two sector plates A26 to synchronously open towards two sides around the pin B38. Meanwhile, the two guide seats B13 drive the two supporting mechanisms 45 to separate from the trunk, the arc plates in the supporting mechanisms 45 swing back and forth to reset relative to the corresponding telescopic rods 46 under the reset action of the corresponding spiral springs 56, and the telescopic rods 46 in the supporting mechanisms 45 restore to the original length under the action of the corresponding springs C55. When the two guide seats B13 are opened to the initial state around the pin shaft A20, the control system controls the two hydraulic columns C44 to stop contracting. Then, the vehicle body 1 is retracted and brings the two guide shoes B13, the two sector plates a26 and all the components mounted thereon completely out of the trunk circumference.

When the two guide seats B13, the two sector plates A26 and all parts mounted on the sector plates A26 are completely separated from the periphery of a trunk, the control system controls the hydraulic column A7 to drive the U-shaped seat A5 to move to the initial position in the guide seat A3, the control system controls the hydraulic column B9 to drive the swing rod 8 to swing back to the initial state relative to the U-shaped seat A5, and the swing rod 8 drives all parts mounted on the swing rod 8 to swing back to the initial state through the U-shaped seat B11.

The invention has the beneficial effects that: the invention is driven by two sector plates A26 rotating in two guide seats B13 on the same wall to synchronously rotate a plurality of arc plates A39 distributed along a concentric vortex line; if the arc plate A39 is used to convey the soil into the center of the tree trunk, the tree pit where the tree trunk is located is gradually refilled with the soil while the soil is conveyed to the center of the tree trunk. In the process of backfilling the tree pit where the tree is located, the vehicle body 1 is always stopped at the same place, and soil does not need to be backfilled into the annular area of the tree pit where the trunk is located around the trunk of the tree by the vehicle body 1, so that the energy consumption of the vehicle body 1 is low. Meanwhile, the invention backfills the soil around the piled and tree pit at one time, and the backfilling efficiency is higher.
