Description

Technical Field

[0001] The utility model relates to a transplanting hole digging device, which belongs to the field of forestry transplanting hole digging. Background Art

[0002] When transplanting trees, the size of the hole should be determined according to the soil ball specifications or root system of the seedlings. Generally, the diameter of the tree hole should be 50-100 cm larger than the soil ball, and the depth should be increased by 20-40 cm to ensure that the root system has enough space to expand. The upper and lower diameters of the tree hole should be unified to avoid forming a pot-bottom shape or a cone, so as to facilitate the expansion of the tree root system and the compaction of the soil. In the prior art, a motor is used to drive the digging drill bit to rotate underground to perform the tree hole digging operation. During the digging process, the shallow soil and the deep soil of the tree hole should be piled separately. The shallow soil is relatively fertile and should be filled to the roots of the tree. The bottom soil is placed on the surface and its structure will change after being exposed to wind and sun, becoming loose and fertile. However, when using a drill bit to dig a tree hole, due to the drill bit rotating too fast, the soil will splash around the tree hole along the inertia generated by the rotation of the drill bit, thereby increasing the difficulty of soil collection. It is necessary to manually clean the soil around and stack it together, which increases the workload when digging the hole. Therefore, it is necessary to design a transplanting and digging device that is convenient for collecting the soil dug out from the tree hole. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide a transplanting and digging device to solve the problems raised in the above-mentioned background technology. The present invention improves the efficiency of collecting soil and avoids soil splashing everywhere.

[0004] In order to achieve the above-mentioned purpose, the utility model is implemented through the following technical solutions: a transplanting and digging device, comprising a fixed top plate, a driving motor is installed on the top of the fixed top plate, a drill bit is installed on the output end of the driving motor, the drill bit is located on the lower side of the fixed top plate, and limit frames are symmetrically installed on both sides of the fixed top plate, the limit frames are sleeved on the support plate, limit plates are installed on the tops of the two support plates, rollers are installed on the bottoms of the two support plates, a handle is installed on the rear side of the fixed top plate, two shielding frames are symmetrically installed on the bottom of the fixed top plate, a discharge port is installed on one side of the shielding frame, the shielding frame is movably installed on the bottom of the first extension frame, the first extension frame is movably installed on the bottom of the second extension frame, the second extension frame is slidably installed on the bottom of the fixed top plate, a partition structure is installed on one side of the first extension frame and the second extension frame, and telescopic parts are installed on the shielding frame and the first extension frame.

[0005] Furthermore, two slide rails are symmetrically installed on the bottom of the fixed top plate, and the two slide rails are respectively located on both sides of the drill bit. Slide bars are installed inside the slide rails, and the slide bars are fixedly installed above the two second extension frames.

[0006] Furthermore, the telescopic part includes a card block, and two card blocks are symmetrically installed on the shielding frame and the first extension frame. A push plate is installed above the card block. The card block and the push plate are both inserted in the movable groove, and the movable groove is opened inside the first extension frame and the second extension frame.

[0007] Furthermore, two guide plates are symmetrically installed inside the shielding frame, and the two guide plates are respectively installed on both sides of the discharge port. The guide plates are inclined toward the side close to the discharge port, and the cross section of the guide plates is triangular.

[0008] Furthermore, the first extension frame and the second extension frame are both provided with through holes, the positions of the through holes correspond to the positions of the discharge ports, and a barrier structure is installed inside the through holes.

[0009] Furthermore, the partition structure includes a storage box, which is located on the upper side of the through hole, and the storage boxes are installed on the inner sides of the second extension frame and the first extension frame. A central axis is installed inside the storage box, and a clockwork spring is installed on the central axis. A curtain is installed on the other end of the clockwork spring, and a counterweight block is installed on the other end of the curtain. The bottom of the counterweight block is connected to the positioning block, and two positioning blocks are symmetrically installed on the inner wall of the through hole.

[0010] The beneficial effects of the present invention are as follows: a transplanting and digging device of the present invention drives the drill bit to rotate by a driving motor, so that the drill bit drills deep along the soil surface to perform tree hole digging operations, and the soil excavated from the tree hole will be transmitted to the outside of the tree hole along the rotation inertia of the blade on the drill bit, and the soil will be splashed and hit in the shielding frame by inertia, and the soil excavated later will push the soil excavated earlier along the guide plate to the outside of the discharge port, thereby reducing the range of soil splashing and facilitating the collection and classification of the soil.

[0011] When the drill bit is moved to a suitable position, the bottom of the shielding frame will fit in with the soil surface. When the drill bit gradually digs a tree hole deeper into the soil, the shielding frame will drive the card block to move in the moving groove, so that the shielding frame will shrink into the first extension frame and the second extension frame, so that the distance between the shielding frame and the first extension frame and the second extension frame can change synchronously according to the depth of the tree hole, thereby improving the efficiency of tree hole excavation, and the shielding frame is always in contact with the outer surface of the soil, which is convenient for collecting the excavated soil.

[0012] With the support of the weight of the counterweight block, when the shielding frame does not retract into the first extension frame and the second extension frame, the top of the discharge port does not support the weight of the bottom of the counterweight block, and will not trigger the spring spring to drive the curtain to retract. The counterweight block will fit with the positioning block, so that the curtain will block the through hole, preventing dust from splashing out of the first extension frame and the second extension frame from the through hole.

Through the cooperation of the provided roller 4 and the handle 2, the slide rail 10 can be moved to the position where it needs to be used, reducing the effort spent on carrying the drill bit 11.

[0021] See also Figure 2 and Figure 3 , two slide rails 10 are symmetrically installed at the bottom of the fixed top plate 1, and the two slide rails 10 are respectively located on both sides of the drill bit 11. A sliding bar is installed inside the slide rail 10, and the sliding bar is fixedly installed above the two second extension frames 14. The telescopic member includes a card block 17, and two card blocks 17 are symmetrically installed on the shielding frame 6 and the first extension frame 13.

[0023] Specific implementation method: The drill bit 11 is driven by the driving motor 9 to rotate, so that the drill bit 11 drills deep along the soil surface to perform a tree hole excavation operation. The soil excavated from the tree hole will be transmitted to the outside of the tree hole along the rotation inertia of the blade on the drill bit 11, and the soil will be splashed and hit in the shielding frame 6 by inertia. The soil excavated later will push the soil excavated earlier along the guide plate 12 to the outside of the discharge port 7, reducing the range of soil splashing and facilitating the collection and classification of the soil. When the drill bit 11 is moved to a suitable position, the bottom of the shielding frame 6 will fit the soil surface. When the drill bit 11 gradually excavates a tree hole deep into the soil, the shielding frame 6 will drive the block 17 to move its position in the moving groove 16, so that the shielding frame 6 moves to the first extension frame 13 and the second extension frame 14, so that the distance between the shielding frame 6 and the first extension frame 13 and the second extension frame 14 can be changed synchronously according to the depth of the tree hole, thereby improving the efficiency of tree hole excavation, and the shielding frame 6 is always in contact with the outer surface of the soil, which is convenient for collecting the excavated soil. Through the weight support of the counterweight block 21, when the shielding frame 6 does not retract into the first extension frame 13 and the second extension frame 14, the top of the discharge port 7 does not support the weight of the bottom of the counterweight block 21, and will not trigger the clockwork spring to drive the curtain 20 to retract. The counterweight block 21 will be in contact with the positioning block 22, so that the curtain 20 blocks the through hole 15, and prevents dust from splashing out of the first extension frame 13 and the second extension frame 14 from the through hole 15.
