[0002] A hole-digging device is a tool used in gardening operations to improve planting efficiency and accuracy. Typically, this device helps to dig holes quickly and evenly for planting trees, flowers, or other plants.

[0003] When using a posthole digger to dig holes for planting in a garden, the digger is started and travels within the planting area. Simultaneously, its internal control module activates the cylinder and motor. The motor drives the drill bit to rotate at high speed, while the cylinder moves the slider, motor, and rotating drill bit downwards, digging a hole in the ground to facilitate tree planting. Since existing drill bit sizes are usually fixed, the required planting hole size varies depending on the size of the plant. This necessitates frequent changes of different drill bit sizes during construction, causing inconvenience and wasting considerable time, thus reducing planting efficiency. Utility Model Content

[0004] The technical problem this utility model aims to solve is that, since the existing drill bit sizes are usually fixed, the required planting pit size will also be different when the size of the planted plants is different. This leads to the need to frequently change different sizes of drill bits according to actual needs during construction, causing inconvenience in carrying them. At the same time, changing and disassembling drill bits will take up a lot of time and reduce planting efficiency.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a garden planting hole-digging device, including a hole digger, a slider is slidably installed on the inner wall of one side of the hole digger, a cylinder is fixedly installed on one side of the hole digger, the output end of the cylinder passes through one side of the hole digger and is fixedly connected to one side of the slider, a motor is fixedly installed on one side of the slider, the output end of the motor passes through one side of the slider and a grooved rod is fixedly installed by means of a coupling, and an adjustment device is provided on one side of the grooved rod. The adjustment device can adjust the outward opening distance of the drill rod on the conical block through the pushing cooperation of the first screw hole block, the threaded rod and the connecting rod to achieve drill bits of different widths, so as to facilitate drilling foundation pits of different sizes.

[0006] The effect achieved by the above-mentioned components is as follows: When using a post hole digger to dig holes for planting in the garden, the adjustment device can be adjusted to a suitable size according to the planting needs, so that the post hole digger can dig pits of different sizes to accommodate the planting of different sized plants. When digging the pit, the post hole digger will be started and will travel in the planting area. At the same time, its internal control module will control the start cylinder and motor. The motor will drive the adjusted drill rod to rotate at high speed, while the cylinder will drive the slider, motor and rotating drill rod to move downward, digging a pit in the ground to facilitate the planting of trees.

[0007] Preferably, the adjusting device includes a threaded rod and a conical block, wherein one side of the conical block is fixedly installed on one end of the threaded rod, and one end of the threaded rod is inserted into the inner wall of the grooved rod; a plurality of drill rods, wherein one end of each drill rod is rotatably installed in the inner wall of one end of the conical block, and a connecting rod is rotatably installed on the inner wall of one end of each drill rod; a first threaded hole block, wherein the inner wall of the first threaded hole block is helically fitted onto the outer surface of the threaded rod, and a circular ring block is rotatably installed on the outer surface of the first threaded hole block, wherein several interiors of the outer surface of the circular ring block are rotatably connected to one end of each of the connecting rods; a limiting mechanism, wherein the limiting mechanism is disposed between the outer surface of the first threaded hole block and one side of the circular ring block, for limiting and fixing the adjusted first threaded hole block; and an easy-installation mechanism, wherein the easy-installation mechanism is disposed between one end of the threaded rod and the inner wall of the grooved rod, for facilitating the quick installation or removal of one end of the threaded rod from the grooved rod.

[0008] The effect achieved by the above-mentioned components is as follows: By setting an adjustment device, before using the hole digger, the threaded rod can be fixedly installed on the grooved rod with the help of an easy-to-install mechanism. Then, according to the size of the foundation pit to be dug, the first screw hole block is manually held and rotated on the threaded rod a certain number of times. This drives the ring block to move downwards, so that under the connection of the connecting rod, the drill rod can be rotated to a certain angle on one end of the connecting rod and in the inner wall of the conical block, expanding outwards with the threaded rod as the center. Then, a second limiting mechanism is used for secondary limiting and fixing. In this way, when the motor is started and drives the grooved rod and the threaded rod to rotate, a foundation pit of the corresponding size can be drilled, which is convenient for planting suitable plants. Through this adjustment, the frequency of disassembling and replacing drill bits can be reduced, and the need to carry several drill bits during landscaping planting can be avoided, making it convenient to carry and transport, while improving planting efficiency.

[0009] Preferably, a telescopic cover is fixedly installed on one side of the first screw hole block, wherein the inner wall of the telescopic cover is sleeved on the outer surface of the threaded rod and the other end is rotatably installed on one side of the conical block.

[0010] The effect achieved by the above-mentioned components is that by setting up a telescopic cover, the outer surface of the threaded rod between the first screw hole block and the conical block can be covered, so that when drilling the foundation pit, the soil is less likely to get stuck on the threaded rod and affect subsequent use.

[0012] The effect achieved by the above components is as follows: by setting a limiting mechanism, after the first screw hole block is rotated to a certain number of turns, the ring block moves downward and drives the connecting rod to open the drill rod to a certain angle. Then, the bolt can be manually held and inserted into the second screw hole block and the corresponding thread groove. This can limit and fix the first screw hole block after rotation, so that the first screw hole block is not easy to slip or loosen on the thread rod during the use of the drill rod, thus improving the efficiency of digging holes and planting.

[0013] Preferably, the easy-installation mechanism includes two locking blocks, symmetrical locking holes on the inner wall of the grooved rod, and symmetrical sliding grooves on the outer surface of one end of the threaded rod, wherein the locking blocks are slidably installed in the inner wall of the sliding grooves and one end is inserted into the inner wall of the locking holes; and two springs, wherein the two ends of the springs are respectively fixedly installed on one side of the locking blocks and one side of the inner wall of the sliding grooves.

[0014] The effect achieved by the above-mentioned components is as follows: by setting up an easy-to-install structure, when using a post hole digger to drill foundation pits, the locking block can be manually pressed inward into the groove on the threaded rod to a certain position, so that one end is completely retracted into the groove. After that, the spring will contract, and then one end of the threaded rod can be inserted into the inner wall of the grooved rod. At this time, the locking block is released, and under the reset action of the spring, one end can be locked into the locking hole. Thus, the threaded rod can be quickly fixed in the inner wall of the grooved rod for later use in drilling foundation pits.

[0015] Preferably, a support rod is fixedly installed on one side of the inner wall of the slide groove, and one end of the support rod is inserted into the inner wall of the spring and slidably connected to the inner wall of the block.

[0016] The effect achieved by the above components is that by setting support rods, the inner walls of the locking block and spring can be supported and reinforced, making them less prone to damage during use and increasing their service life.

[0017] Preferably, the longitudinal section of the card block is U-shaped, and the height of the side of the card block closest to the first screw hole block is higher than the height of the other end.

[0018] The effect achieved by the above-mentioned components is that by setting the locking block in a U-shape, with one end higher than the other, it is convenient to manually press the higher end when removing it, making it easy to disassemble and replace.

[0019] Preferably, a limiting block is symmetrically fixedly installed on the outer surface of one end of the threaded rod, and a limiting groove is symmetrically opened on the inner wall of the grooved rod, with the limiting block inserted into the inner wall of the limiting groove.

[0020] The effect achieved by the above components is as follows: by setting the limiting block and the limiting groove, when one end of the threaded rod is inserted into the grooved rod, the limiting block can be aligned with the limiting groove and inserted into it. This ensures that the locking block can be quickly aligned with the locking hole, making it convenient to install and fix it.

[0021] The beneficial effects of this utility model are:

[0022] By setting an adjustment device, before using the post hole digger, the threaded rod can be fixedly installed on the grooved rod using an easy-to-install mechanism. Then, according to the required size of the foundation pit to be dug, manually hold the first threaded hole block and rotate it on the threaded rod a certain number of times. This causes the ring block to move downwards, which, under the push of the connecting rod, drives the drill rod to rotate to a certain angle on one end of the connecting rod and the inner wall of the conical block, expanding outwards around the threaded rod. Then, a limiting mechanism is used for secondary limiting and fixing. In this way, when the motor is started and drives the grooved rod and the threaded rod to rotate, a foundation pit of the corresponding size can be drilled, making it convenient to plant suitable plants. This adjustment reduces the frequency of disassembling and replacing drill bits, avoids the need to carry several drill bits when planting in the garden, facilitates carrying and transportation, and improves planting efficiency.

The output end of the motor 5 passes through one side of the slider 4 and is fixedly installed with a grooved rod 6 by means of a coupling. An adjustment device 2 is provided on one side of the grooved rod 6. The adjustment device 2 can adjust the outward opening distance of the drill rod 23 on the conical block 22 through the pushing cooperation of the first screw hole block 25, the threaded rod 21, and the connecting rod 24 to achieve drill bits of different widths, so as to facilitate the drilling of foundation pits of different sizes. When using a post hole digger 1 to dig holes for planting in a garden, the adjustment device 2 can be adjusted to a suitable size according to the planting needs, so that the post hole digger 1 can drill holes of different sizes to accommodate the planting of different sized plants. When digging the holes, the post hole digger 1 will be started and will move in the planting area. At the same time, its internal control module will control the start cylinder 3 and motor 5. The motor 5 will drive the adjusted drill rod 23 to rotate at high speed, while the cylinder 3 will drive the slider 4, motor 5 and rotating drill rod 23 to move downward, digging a hole in the ground to facilitate the planting of trees.

[0032] Figure 1-4 The adjusting device 2 shown includes a threaded rod 21 and a conical block 22, wherein one side of the conical block 22 is fixedly installed on one end of the threaded rod 21, and one end of the threaded rod 21 is inserted into the inner wall of the grooved rod 6; a plurality of drill rods 23, wherein one end of each drill rod 23 is rotatably installed in the inner wall of one end of the conical block 22, and a connecting rod 24 is rotatably installed on the inner wall of one end of the drill rod 23; a first threaded hole block 25, wherein the inner wall of the first threaded hole block 25 is helically sleeved on the outer surface of the threaded rod 21, and the outer surface of the first threaded hole block 25 is... A circular ring block 26 is rotatably mounted, wherein several internal parts of the outer surface of the circular ring block 26 are rotatably connected to one end of several connecting rods 24; a limiting mechanism 28 is disposed between the outer surface of the first screw hole block 25 and one side of the circular ring block 26, for limiting and fixing the adjusted first screw hole block 25; an easy-installation mechanism 27 is disposed between one end of the threaded rod 21 and the inner wall of the grooved rod 6, for facilitating the quick installation or removal of one end of the threaded rod 21 from the grooved rod 6. By setting the adjustment device 2, before using the hole digger 1, the threaded rod 21 can be fixedly installed on the grooved rod 6 with the help of the easy installation mechanism 27. Then, according to the size of the foundation pit to be dug, the first screw hole block 25 is manually held and rotated on the threaded rod 21 to a certain number of turns, which drives the ring block 26 to move downward. Thus, under the connection and push of the connecting rod 24, the drill rod 23 is driven to rotate to a certain angle on one end of the connecting rod 24 and in the inner wall of the conical block 22, expanding outward with the threaded rod 21 as the center. Then, the limiting mechanism 28 is used for secondary limiting and fixing. In this way, when the starting motor 5 drives the grooved rod 6 and the threaded rod 21 to rotate, a foundation pit of the corresponding size can be drilled, which is convenient for planting suitable plants. Through this adjustment, the frequency of disassembling and replacing drill bits can be reduced, and the situation of needing to carry several drill bits during garden planting can be avoided, which is convenient for carrying and transporting, and at the same time improves planting efficiency.

[0033] Figure 1-4A telescopic cover 29 is fixedly installed on one side of the first threaded hole block 25, wherein the inner wall of the telescopic cover 29 is fitted onto the outer surface of the threaded rod 21, and the other end is rotatably installed on one side of the conical block 22. By setting the telescopic cover 29, the outer surface of the threaded rod 21 between the first threaded hole block 25 and the conical block 22 can be covered, so that during the drilling of the foundation pit, soil is not easily stuck on the threaded rod 21, affecting subsequent use. The limiting mechanism 28 includes a second threaded hole block 282, wherein one side of the second threaded hole block 282 is fixedly installed on the outer surface of the first threaded hole block 25, and a plurality of threaded grooves 281 are opened on one side of the annular block 26; a bolt 283, wherein one end of the bolt 283 is screwed into the inner wall of the second threaded hole block 282 and the threaded grooves 281. By setting a limiting mechanism 28, after rotating the first screw hole block 25 a certain number of times, the ring block 26 moves downward and drives the connecting rod 24 to open the drill rod 23 to a certain angle. Then, the bolt 283 can be manually held and inserted into the second screw hole block 282 and the corresponding thread groove 281. This can limit and fix the first screw hole block 25 after rotation, so that the first screw hole block 25 is not prone to slippage and loosening on the thread rod 21 during the use of the drill rod 23, thereby improving the efficiency of digging holes and planting.

[0034] Figure 1-4 The installation mechanism 27 shown includes two locking blocks 274, symmetrical locking holes 271 on the inner wall of the grooved rod 6, and symmetrical sliding grooves 272 on the outer surface of one end of the threaded rod 21. The locking blocks 274 are slidably installed in the inner wall of the sliding grooves 272, and one end is inserted into the inner wall of the locking holes 271. Two springs 273 are also shown, with the two ends of the springs 273 respectively fixedly installed on one side of the locking blocks 274 and one side of the inner wall of the sliding grooves 272. By setting up an easy-to-install structure, when using the post hole digger 1 to drill and excavate foundation pits, the locking block 274 can be manually pressed inward into the groove 272 on the threaded rod 21 to a certain position, so that one end is completely retracted into the groove 272. This causes the spring 273 to contract, and then one end of the threaded rod 21 can be inserted into the inner wall of the grooved rod 6. At this time, the locking block 274 is released, and under the reset action of the spring 273, one end can be locked into the locking hole 271. Thus, the threaded rod 21 can be quickly fixed in the inner wall of the grooved rod 6 for later use in drilling and excavating foundation pits.

[0035] Figure 1-4A support rod 275 is fixedly installed on one side of the inner wall of the slide groove 272 shown. One end of the support rod 275 is inserted into the inner wall of the spring 273 and slidably connected to the inner wall of the locking block 274. By setting the support rod 275, the inner walls of the locking block 274 and the spring 273 can be supported and reinforced, making them less prone to damage during use and improving their service life. The longitudinal section of the locking block 274 is U-shaped, and the height of the side of the locking block 274 near the first screw hole block 25 is higher than the other end. By setting the locking block 274 into a U-shape, with one end higher than the other, it is convenient to manually press the higher end when removing it, making it easy to disassemble and replace. Limiting blocks 276 are symmetrically fixedly installed on the outer surface of one end of the threaded rod 21, and limiting grooves 277 are symmetrically opened on the inner wall of the grooved rod 6. The limiting blocks 276 are inserted into the inner wall of the limiting grooves 277. By setting the limiting block 276 and the limiting groove 277, when one end of the threaded rod 21 is inserted into the grooved rod 6, the limiting block 276 can be aligned with the limiting groove 277 and inserted into it. This ensures that the locking block 274 can be quickly aligned with the locking hole 271, making it convenient to install and fix it.

[0036] Working principle: When digging holes for planting in a garden using the hole digger 1, the locking block 274 can be manually pressed inward into the groove 272 on the threaded rod 21 to a certain position, so that one end is completely retracted into the groove 272. This causes the spring 273 to contract, and then one end of the threaded rod 21 can be inserted into the inner wall of the grooved rod 6. At this time, the locking block 274 is released, and under the reset action of the spring 273, one end can be locked into the locking hole 271. This allows the threaded rod 21 to be quickly fixed in the inner wall of the grooved rod 6 for later use in drilling and digging foundation pits. Then, depending on the size of the excavated pit, manually hold the first screw hole block 25 and rotate it on the threaded rod 21 a certain number of times. This will cause the ring block 26 to move downwards. Under the connection and push of the connecting rod 24, the drill rod 23 will rotate to a certain angle on one end of the connecting rod 24 and the inner wall of the conical block 22, expanding outwards with the threaded rod 21 as the center. Then, manually hold the bolt 283 and insert it into the second screw hole block 282 and the corresponding threaded groove 281. This will limit and fix the rotated first screw hole block 25. When the motor 5 is started and drives the grooved rod 6 and the threaded rod 21 to rotate, a pit of the corresponding size can be drilled, which is convenient for planting suitable plants. This adjustment can reduce the frequency of disassembling and replacing drill bits, and avoid the need to carry several drill bits when planting in the garden. It is convenient to carry and transport, and at the same time improves planting efficiency. When drilling a foundation pit, the hole digger 1 will be started and will travel within the planting area. At the same time, its internal control module will control the start cylinder 3 and motor 5. Motor 5 will drive the adjusted drill rod 23 to rotate at high speed, while cylinder 3 will drive the slider 4, motor 5 and rotating drill rod 23 to move downward, digging a pit in the ground to facilitate the planting of trees.
