Description

Technical Field

[0001] The present invention relates to the technical field of garden planting, and more specifically, to an efficient shock-absorbing small hole digger for garden planting. Background Art

[0002] The small hole diggers used in current garden operations mainly rely on engines to provide power to drive the equipment. If a wheelbarrow-type hole digger is adopted, it can be easily moved by manpower, and this characteristic shows significant advantages in the equipment transfer link.

[0003] Chinese patent document (CN114667826A) discloses a four-wheeled vehicle with a hole digger for garden tree planting, which states in the specification that "it includes a suspension frame, a gearbox, a drill bit, a fixing device, a suspension device and a universal module. The suspension frame is rotatably connected to the gearbox, the bottom of the gearbox is fixedly connected to the drill bit, a fixing device is installed on the side of the gearbox, and the fixing device is connected to the suspension device through the universal module; by setting a connecting rod, a column rod and a semi-circular block, the gearbox is rotated in the suspension frame by moving the connecting rod, and the controller controls the electric push rod to insert into the first slot, so that the electric push rod drives the semi-circular block to be stuck on the upper surface of the column rod through the ejector rod. Therefore, the angle between the gearbox and the suspension frame is fixed by the column rod and the semi-circular block, so that the drill bit is perpendicular to the ground, and the drill bit can directly dig holes on the slope, reducing the labor burden of the planting personnel and improving the working efficiency of garden planting." However, in actual use, not only does it need to increase the weight of the machine body to improve stability, but it is also easy to increase the transportation burden of the equipment due to the increased weight, resulting in difficulty in ensuring the center of gravity of the equipment and poor stability during operation.

[0004] During the actual excavation operation, when the drill bit contacts the ground and generates a mutual force, the whole hole digger is extremely likely to tip over or even capsize due to the reaction force. To address this problem, there are mainly two solutions commonly adopted in the industry: one is to increase the own tonnage of the hole digger to enhance its stability by increasing the equipment weight; the other is to use a ground fixing device to firmly fix the hole digger on the ground. However, both of these methods have obvious drawbacks: increasing the weight of the hole digger can improve stability to a certain extent, but it will significantly increase the burden of the equipment during transportation and reduce the transportation efficiency; while the ground fixing method can effectively prevent the equipment from tipping over, but the operation process is cumbersome and complex, which will significantly extend the pre-preparation time of the excavation operation, and thus have an adverse impact on the overall use efficiency of the hole digger. In view of this, we propose an efficient shock-absorbing small hole digger for garden planting. Summary of the Invention

[0017] Compared with the prior art, the beneficial effects of the present invention are: 1. The present invention designs a rotating assembly and a pressing assembly. During the pit-digging operation, the driving assembly is started to drive the operation of four driven assemblies, thereby gradually drilling holes downward by the four rotating assemblies. At this time, the initial positioning is completed by means of the weight of the drill. After the initial positioning is completed, the positioning plate is flipped above the handrail through the electric regulator. At this time, the center of gravity of the drill is located outside the base plate. Then, the pump runs, injecting gas along the conduit into the pressure assembly. The pressure assembly squeezes the adjustment assembly, pushing the pressing assembly downward to press the loose soil on the surface of the rotating assembly after it drills into the ground. When the pressure assembly moves to the limit state, a large amount of gas is quickly discharged above the adjustment assembly, and the reaction force generated by the exhaust gas and the pressed soil jointly perform secondary fixation on the device. Since the position of the center of gravity of the drill changes after the positioning plate is flipped, the reaction force received by the drill during pit-digging will use the contact point between the drill and the ground as the base point and the connection between the rotating assembly and the ground as the center of the circle, causing the device to have a tendency to tumble. And a larger reaction force is required to maintain balance in the overturned state, which improves the stability of the device during pit-digging. In addition, if the pressure is too high and the device as a whole has an upward trend, the contact between the rotating assembly and the ground will play a reinforcing role, and at the same time, the pressing assembly presses the soil after the rotating assembly drills into the ground, further improving the stability of the device during use.

[0018] 2. The present invention also designs a rotating assembly and a driven assembly. When the motor runs, it drives one of the driven gears to rotate through the driving gear, and the four driven gears then achieve synchronous rotation via the transmission belt. At this time, the limit block drives the drill rod to rotate. During the rotation of the drill rod, relying on the cooperation between its thread groove and the nut, it gradually moves downward. As the drill rod rotates and moves downward, the spiral blade below it gradually penetrates into the ground. When most of the drill rod extends into the ground, the initial positioning of the device is completed. After the initial positioning is completed, the electric regulator can be started to prepare for the pit-digging operation. After the spiral blade penetrates into the ground, the contact area between the drill rod and the underground soil is increased. After adjusting the position of the drill, the drill will not easily squeeze the whole device to make it rise, but will show an inclined state after being stressed and adjusted. This inclined state maximally improves the stability of the device during pit-digging, effectively avoiding the problem that the device affects the pit-digging effect due to large vibrations, and thus improving the safety of the device during use.

[0019] 3. The present invention also designs a pressing component and a pressure component. After the drill pipe is initially positioned and the position of the drilling rig is adjusted, the pump machine needs to be started. The pump machine inputs gas into the two sliding sleeves through the conduit respectively, increasing the pressure inside the sliding sleeves. At this time, the sliding cylinder pushes the push block to squeeze the slider, and the slider moves downward along the inclined planes on both sides. When the sliding cylinder enters the sealing shell, the exhaust groove above the sliding cylinder communicates with the sealing shell, and a large amount of gas quickly discharges along the sealing shell. At the same time, the downward-moving slider pushes the pressing plate to contact and squeeze the ground, and the squeezing position is exactly the area where the drill pipe drills into the ground, thereby squeezing the soil around the drill pipe. In addition, a large amount of gas discharges from bottom to top, playing a dual reinforcement role: on the one hand, the friction between the pressed soil and the drill pipe and the spiral blades increases, improving the stability of the device during use; on the other hand, the gas discharged from bottom to top further reinforces the device under the reaction force, further improving the stability and safety of the device during use.

Detailed implementation mode

[0022] As Figures 1 to 8 shown, a high-efficiency shock-absorbing small hole digger for garden planting involved in the present invention includes a roller 14, a motor 241, a drill 125 and a driver 124, and further includes The body mechanism 1 includes a base component 11, a reinforcement component 12 connected to the base component 11, a vertical plate 13 above the base component 11, a roller 14, and an electric regulator 15. Among them, the electric regulator 15 is connected to the vertical plate 13, and the roller 14 is located below the base component 11; and, the positioning mechanism 2 includes four rotating components 21, four driven components 22 respectively connected to the four rotating components 21, the four driven components 22 are connected by a transmission belt 23, and a driving component 24. Among them, the driving component 24 is connected to one of the driven components 22; and, the pressure mechanism 3 includes two pressing components 31, an adjusting component 32 above the pressing component 31, a pressure component 33 connected to the adjusting component 32, a conduit 34, and a pump 35. Among them, the conduit 34 is connected to the pressure component 33, and the other end of the conduit 34 is connected to the pump 35. By designing the rotating component 21 and the pressing component 31, during the pit-digging operation, the driving component 24 is started to drive the four driven components 22 to operate, and then the four rotating components 21 gradually drill holes downward. At this time, the initial positioning is completed by means of the weight of the drill 125. After the initial positioning is completed, the positioning plate 123 is flipped to above the armrest 16 by the electric regulator 15. At this time, the center of gravity of the drill 125 is located outside the base plate 111. Then, the pump 35 operates to inject gas along the conduit 34 into the pressure component 33. The pressure component 33 squeezes the adjusting component 32 to push the pressing component 31 downward to press the loose soil on the surface of the rotating component 21 after it drills into the ground. When the pressure component 33 moves to the limit state, a large amount of gas is quickly discharged above the adjusting component 32. The reaction force generated by the exhaust gas and the pressed soil jointly fix the device for the second time. Since the center of gravity position of the drill 125 changes after the positioning plate 123 is flipped, the reaction force received by the drill 125 during pit-digging will use the contact point between the drill 125 and the ground as the base point and the connection between the rotating component 21 and the ground as the center of the circle, prompting the device to have a tendency to tumble. And a larger reaction force is required to maintain the balance in the side-tip state, which improves the stability of the device during pit-digging. In addition, if the pressure is too high and causes the whole device to have an upward trend, the contact between the rotating component 21 and the ground will play a reinforcing role. At the same time, the pressing component 31 presses the soil after the rotating component 21 drills into the ground, further improving the stability of the device during use.

[0023] In the embodiment of the present invention, the upper part of the base assembly 11 is fixedly connected to the lower part of the reinforcement assembly 12, the upper part of the base assembly 11 is fixedly connected to the vertical plate 13, one side of the vertical plate 13 is fixedly connected to the electric regulator 15, the other end of the electric regulator 15 is fixedly connected to the reinforcement assembly 12, the number of rollers 14 is four, and the four rollers 14 are all arranged below the base assembly 11, the reinforcement assembly 12 is fixedly connected to the handrail 16, the handrail 16 adopts a concave design, the number of rotating assemblies 21 is four, and the four rotating assemblies 21 are respectively located at four driven assemblies 22, one of which is a driven assembly The components 22 are meshed with the driving components 24, the four driven components 22 are connected by the transmission belt 23, the top of the base component 11 is fixedly connected to the four driven components 22, the driving component 24 is clamped on the top of the base component 11, the number of the pressing components 31 is two, the tops of the two pressing components 31 are fixedly connected to the same adjustment component 32, the two sides of the adjustment component 32 are fixedly connected to the two pressure components 33 respectively, the two pressure components 33 are connected by the conduit 34, the other end of the conduit 34 is connected to the pump 35, the adjustment component 32 is fixedly connected in the base component 11, the pressing component The pump 31 is sleeved on the outside of the rotating assembly 21, and the pump 35 is fixedly connected to the top of the base assembly 11. By designing the rotating assembly 21 and the driven assembly 22, when the motor 241 is running, it will drive one of the driven gears 223 to rotate through the driving gear 242, and the four driven gears 223 will then realize synchronous rotation through the transmission belt 23. At this time, the limit block 226 drives the drill rod 211 to rotate. During the rotation process, the drill rod 211 gradually moves downward by virtue of the cooperation between its thread groove 213 and the nut 113. As the drill rod 211 rotates and moves downward, the spiral blade 214 below it gradually penetrates into the ground. When the drill rod 211 rotates and moves downward, the spiral blade 214 below it gradually penetrates into the ground. After most of the rod 211 is extended into the ground, the preliminary positioning of the device is completed. After the preliminary positioning is completed, the electric regulator 15 can be started to prepare for digging operations. After the spiral blades 214 penetrate deep into the ground, the contact area between the drill rod 211 and the underground soil is increased. After adjusting the position of the drilling rig 125, the drilling rig 125 will not easily squeeze the entire device to make it rise, but will be in an inclined state after the force is adjusted. This inclined state maximizes the stability of the device during digging, effectively avoids the problem of the device affecting the digging effect due to large-scale vibration, and thus improves the safety of the device during use.

[0024] In an embodiment of the present invention, the base assembly 11 includes a base plate 111. An installation groove 112 is formed above the base plate 111. Nuts 113 are fixedly connected to the four corners above the base plate 111. A placement groove 114 is formed above the base assembly 11. The upper part of the base plate 111 is fixedly connected to the bottom ends of the reinforcement assembly 12 and the vertical plate 13. The rotating assembly 21 is threadedly connected to the nuts 113. The driving assembly 24 is clamped above the base plate 111. The pump 35 is fixedly connected above the base plate 111. The adjusting assembly 32 is fixedly connected in the installation groove 112. Since the rotating assembly 21 is small in size, the reaction force during drilling is small, and the drilling can be completed by the weight of the drill 125, ensuring the stability of the device during the initial positioning of the device.

[0025] The reinforcement assembly 12 includes two reinforcement rods 121. A rotating rod 122 is clamped between the two reinforcement rods 121. A positioning plate 123 is fixedly connected to the outside of the rotating rod 122. The positioning plate 123 is L-shaped. A driver 124 is fixedly connected above the positioning plate 123. A drill 125 is fixedly connected below the positioning plate 123. The driver 124 is in transmission connection with the drill 125.

The reinforcement rods 121 are fixedly connected above the base plate 111. The two reinforcement rods 121 are fixedly connected to the same armrest 16. By designing the pressing assembly 31 and the pressure assembly 33, after the initial positioning of the drill pipe 211 is completed and the position of the drill 125 is adjusted, the pump 35 needs to be started. The pump 35 inputs gas into the two sliding sleeves 331 through the conduit 34 respectively, increasing the pressure inside the sliding sleeves 331. At this time, the sliding cylinder 332 pushes the push block 335 to squeeze the slider 322, and the slider 322 moves downward along the inclined surfaces on both sides thereof. When the sliding cylinder 332 enters the sealing shell 321, the exhaust groove 333 above the sliding cylinder 332 communicates with the sealing shell 321, and a large amount of gas quickly discharges along the sealing shell 321. At the same time, the downward moving slider 322 pushes the pressing plate 311 to contact and squeeze the ground, and the squeezing position is exactly the area where the drill pipe 211 drills into the ground, thereby squeezing the soil around the drill pipe 211. In addition, a large amount of gas is discharged from bottom to top, playing a dual reinforcement role: on the one hand, the friction between the pressed soil and the drill pipe 211 and the spiral blade 214 increases, improving the stability of the device during use; on the other hand, the gas discharged from bottom to top further reinforces the device under the reaction force, further improving the stability and safety of the device during use.

[0026] As another embodiment of the present invention, the rotating assembly 21 includes a drill pipe 211. Three limiting grooves 212 are formed on the outer surface of the drill pipe 211. A threaded groove 213 is formed on the outer surface of the drill pipe 211. A spiral blade 214 is fixedly connected to the outer surface of the drill pipe 211.

The two limiting cylinders 222 are respectively clamped in the two card slots 224. A sleeve 225 is fixedly connected inside the driven gear 223. Three limiting blocks 226 are fixedly connected inside the sleeve 225. The bracket 221 is fixedly connected above the base plate 111. The three limiting blocks 226 are respectively slidably connected in the three limiting grooves 212 formed on the outer surface of the drill pipe 211. Four driven gears 223 are meshed through a transmission belt 23. The driving assembly 24 includes a motor 241. The output shaft of the motor 241 is fixedly connected to a driving gear 242.

The driving gear 242 is meshed with one of the driven gears 223. The position of the drill 125 is adjusted through a rotating rod 122 and an electric regulator 15. The reaction force generated when the drill 125 contacts the ground during digging will push the base plate 111 to turn and move due to the different positions of the drill 125. When the base plate 111 is in a turned state, the drill pipe 211 moves downward to remain vertically downward. At this time, the drill pipe 211 and the spiral blade 214 will be squeezed against the unloosened soil underground, resulting in an increase in the difficulty of turning the base plate 111, thereby improving the equipment stability of the device during digging operations.

[0027] As another embodiment of the present invention, the pressing assembly 31 includes two pressing plates 311. The two pressing plates 311 are fixedly connected by a connecting bar 312.

The sliding sleeve 331 is fixedly connected to one side of the sealing shell 321. The push block 335 is clamped outside the slider 322. The sliding sleeve 331 is communicated with the conduit 34. When the motor 241 runs in the reverse direction, the drill rod 211 can be taken out of the soil, and the pressing plate will also clean the thread groove 213 and the limiting groove 212 outside the drill rod 211 to ensure the service life of the device.

[0028] Working principle: This embodiment provides a high-efficiency shock-absorbing small hole-digging machine for garden planting. When in use, the reinforcement assembly 12 is adjusted through the electric regulator 15 so that it is located above the base assembly 11. Then, the armrest 16 can be pushed to move the position of the device. After moving to the hole-digging position in the garden, the device is positioned through the positioning mechanism 2, and after positioning, it is secondarily reinforced through the pressure mechanism 3. Then, the ground can be dug through the drill 125. During the hole-digging operation, the driving assembly 24 is started, which drives the four driven assemblies 22 to operate. During the operation of the driven assemblies 22, the four rotating assemblies 21 gradually drill holes downward, and at the same time, the initial positioning is completed by means of the weight of the drill 125. After the initial positioning is completed, the electric regulator 15 is operated to flip the positioning plate 123 so that it flips above the armrest 16. At this time, the center of gravity of the drill 125 moves outside the base plate 111. Then, the pump 35 is started, and the pump 35 injects gas into the pressure assembly 33 along the conduit 34. After the pressure assembly 33 is pressurized, it squeezes the adjusting assembly 32, and then pushes the pressing assembly 31 to move downward to press the loose soil on the surface after the rotating assembly 21 drills into the ground. When the pressure assembly 33 moves to the limit state, a large amount of gas is quickly discharged above the adjusting assembly 32, generating a reaction force through the exhaust. Using the reaction forces generated by pressing the soil and gas discharge, the device is secondarily fixed together. When the motor 241 operates, it drives one of the driven gears 223 to rotate through the driving gear 242. The four driven gears 223 then rotate synchronously via the transmission belt 23. At this time, the limit block 226 drives the drill pipe 211 to rotate. During the rotation of the drill pipe 211, by virtue of the cooperation between its thread groove 213 and the nut 113, it gradually moves downward. As the drill pipe 211 rotates and moves downward, the spiral blade 214 below it gradually penetrates into the ground. When most of the drill pipe 211 extends into the ground, the preliminary positioning of the device is completed. At this time, the electric regulator 15 can be started to prepare for the subsequent pit-digging operation; After the preliminary positioning of the drill pipe 211 is completed and the position of the drill rig 125 is adjusted, the pump 35 needs to be started. The pump 35 inputs gas into the two sliding sleeves 331 respectively through the conduit 34, increasing the pressure inside the sliding sleeves 331. At this time, the sliding cylinder 332 pushes the push block 335 to squeeze the slider 322, and the slider 322 moves downward along the inclined surfaces on both sides. When the sliding cylinder 332 enters the sealing housing 321, the exhaust groove 333 above the sliding cylinder 332 communicates with the sealing housing 321, and a large amount of gas quickly discharges along the sealing housing 321. At the same time, the downward-moving slider 322 pushes the pressing plate 311 to contact and squeeze the ground, and the squeezing position is exactly the area where the drill pipe 211 drills into the ground, thereby squeezing the soil around the drill pipe 211, and a large amount of gas discharges from bottom to top.
