Description

Technical Field

[0001] The present invention relates to the technical field of garden engineering construction equipment, in particular to an automatic pit digging device for tree planting in garden greening engineering construction. Background Art

[0002] In the construction of landscaping projects, tree planting is a key task, and digging holes as the primary link in tree planting has a direct impact on the progress of the entire project and the survival rate of trees. The traditional method of digging holes for tree planting mainly relies on manual excavation. This method is not only labor-intensive and inefficient, but also difficult to ensure that the size and verticality of the pits meet the requirements, thus affecting the growth and stability of trees. With the continuous development of science and technology, some mechanized digging equipment has gradually been used in landscaping projects.

[0003] Current automatic digging equipment generally adopts two types: trolley type or handheld type. When facing complex terrain, such as irregular slopes and areas where it is inconvenient for trolleys to drive, only handheld type can be used for digging. However, when the current handheld digging equipment is in use, when drilling and digging holes under the downward force, the force may be too great, resulting in excessive feed of the spiral digging drill bit, which may cause damage to the power mechanism under high load. In addition, when the spiral digging drill bit encounters hard stones or other objects, its reaction is directly applied to the worker's hand without buffering, and the worker may reflexively loosen the equipment. At this time, the equipment has certain safety hazards. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide an automatic pit digging device for tree planting in landscaping engineering construction that can overcome the above problems or at least partially solve the above problems.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions: Disclosed is an automatic pit-digging device for tree planting in landscaping engineering construction, comprising: a frame and a controller arranged on the frame, and also comprising: a power mechanism fixedly arranged in the frame; a spiral pit-digging drill bit arranged at the output end of the power mechanism; a fixed sleeve symmetrically fixedly connected to both sides of the frame; a rotating shaft rotatably arranged in the fixed sleeve; a hand-held rod symmetrically fixedly connected to both ends of the rotating shaft, and a handle is provided at the end of the hand-held rod, and a plug is provided at the end of the handle; a connecting plate fixedly arranged between two adjacent hand-held rods; a positioning plate symmetrically arranged on the frame; and a strong spring symmetrically fixedly connected between the positioning plate and the connecting plate.

[0006] Preferably, a first limiting plate is symmetrically fixedly connected to the frame, and when two workers lift the digging equipment through the handle and the handheld rod, the connecting plate fits with the first limiting plate.

[0007] In order to facilitate the limiting of the hand-held rod, preferably, a second limiting plate is symmetrically fixedly connected to the frame, and a first distance is set between the second limiting plate and the connecting plate.

[0008] In order to adapt to soils of different hardness, a second electric telescopic rod is symmetrically fixedly connected to the frame, and the output end of the second electric telescopic rod is fixedly connected to the positioning plate. The controller controls the contraction of the second electric telescopic rod to adjust the position of the positioning plate, thereby adjusting the stretched state of the strong spring in the initial state to adapt to soils of different hardness.

[0009] In order to facilitate reminding the staff of the tilt of the frame, preferably, a plurality of through holes are opened on the upper side of the handle, and a protruding rod is slidably arranged in the through holes. A fixing plate is fixedly connected between the plurality of protruding rods, and a first electric telescopic rod is fixedly connected between the fixing plate and the inner wall of the handle.

[0010] In order to facilitate the leveling of the frame, an electronic inclinometer is further fixedly connected to the first limit plate. When the electronic inclinometer detects that the frame is tilted to one side, the controller controls the second electric telescopic rod on the other side to retract, so that the force of the staff's hand is applied to the tilted end of the frame through the handheld rod to restore it to a horizontal state.

[0011] Preferably, a fixing ring is fixedly connected to the fixing sleeve, a sliding rheostat is provided on the fixing ring, and a conductive block is fixedly connected to the rotating shaft.

[0012] In order to facilitate intuitive observation of the force applied by the staff, a plurality of indicator lights are further provided on the first limit plate. As the distance the conductive block moves on the sliding rheostat increases, the number of the indicator lights that light up in red increases.

[0013] In order to facilitate reducing energy consumption, the sliding rheostat is further provided with a first control zone and a second control zone. When the sliding distance of the conductive block in the first control zone of the sliding rheostat increases, the power mechanism drives the spiral digging drill bit to increase its speed. When the conductive block slides on the second control zone, the speed of the spiral digging drill bit remains unchanged at the maximum speed.

[0014] In order to prevent the power mechanism from working under high load, further, when the conductive block contacts the middle of the second control area of ​​the sliding rheostat, the controller controls the power mechanism to stop.

[0015] Compared with the prior art, the present invention provides an automatic pit digging device for tree planting in landscaping engineering construction, which has the following beneficial effects: 1. The automatic digging equipment for tree planting in the landscaping project construction uses a handle to hold and press down, and a strong spring to buffer the applied force to prevent excessive force from causing the spiral digging drill to feed too much and causing the power mechanism to work under high load. In addition, when the spiral digging drill encounters hard stones or pneumatic objects, a strong spring can be used for buffering to prevent the force from directly acting on the worker's hand and causing the worker to let go, which would cause a safety hazard. The worker can observe the rotation angle of the hand-held rod to avoid contact between the hand-held rod and the second limit plate, and then control the force of his or her downward pressure accordingly to avoid high-load operation of the power mechanism.

[0016] 2. The automatic digging equipment for tree planting in landscaping engineering construction controls the contraction of the second electric telescopic rod through a controller to adjust the position of the positioning plate, thereby changing the initial stretched state of the strong spring. For example, for harder soil, the initial stretching amount of the strong spring can be increased, so that the spiral digging drill bit can obtain greater pressure during operation, while making it easier for workers to better apply force.

[0017] 3. The automatic digging equipment for tree planting in the landscaping project construction, when the electronic inclinometer detects that the frame is tilted toward one of the workers, the controller controls the first electric telescopic rod in the handle on the tilted side to extend, and the first electric telescopic rod drives the convex rod to slide outward. At this time, the worker can feel the convex rod, and the worker can reduce the pressure on the current side accordingly, so that the first electric telescopic rod retracts after the frame returns to horizontal, thereby ensuring the verticality of the foundation pit and facilitating the coordinated work of the two workers. When the electronic inclinometer detects that the frame is tilted to one side, it transmits the tilt data to the controller. After analyzing the data, the controller controls the second electric telescopic rod on the other side to retract, and the second electric telescopic rod drives the positioning plate to move, thereby changing the tension of the strong spring, so that the worker's hand applies more force to the tilted end of the frame through the handheld rod, so that the frame returns to a horizontal state. When it returns to a horizontal turntable, the second electric telescopic rod resets, so that the spiral digging drill bit can dig vertically, thereby ensuring the quality of the foundation pit.

[0018] The parts not involved in this device are the same as the existing technology or can be implemented by using the existing technology. When the spiral digging drill bit encounters hard stones or pneumatic objects, the powerful spring can be used for buffering to prevent the force from directly acting on the hands of the workers and causing the workers to let go, which may cause safety hazards. By observing the rotation angle of the hand-held rod, the worker can control the downward force accordingly to avoid high-load operation of the power mechanism. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] Example 1: Reference Figure 1-Figure 7, an automatic digging device for planting trees in landscaping engineering construction, comprising: a frame 1 and a controller 103 arranged on the frame 1, and also comprising: a power mechanism 101, fixedly arranged in the frame 1; a spiral digging drill bit 102, arranged at the output end of the power mechanism 101; a fixed sleeve 2, symmetrically fixedly connected to both sides of the frame 1; a rotating shaft 201, rotatably arranged in the fixed sleeve 2; a hand-held rod 202, symmetrically fixedly connected to both ends of the rotating shaft 201, and a handle 203 is provided at the end of the hand-held rod 202, and a plug 204 is provided at the end of the handle 203; a connecting plate 209, fixedly arranged between two adjacent hand-held rods 202; a positioning plate 5, symmetrically arranged on the frame 1; a strong spring 501, symmetrically fixedly connected between the positioning plate 5 and the connecting plate 209.

[0023] The frame 1 is symmetrically fixed with a first limiting plate 4 . When two workers lift the digging equipment through the handle 203 and the hand-held rod 202 , the connecting plate 209 fits with the first limiting plate 4 .

[0024] When the staff lifts the equipment, the hand-held rod 202 drives the connecting plate 209 to move. When the connecting plate 209 is in contact with the first limiting plate 4, the further rotation of the hand-held rod 202 is restricted, thereby ensuring the stability of the equipment during the lifting process.

[0025] A second limiting plate 403 is symmetrically fixedly connected to the frame 1 , and a first distance 404 is provided between the second limiting plate 403 and the connecting plate 209 .

[0026] The first distance 404 between the connecting plate 209 and the second limiting plate 403 provides a certain amount of space for the hand-held rod 202 to move, and also limits the excessive displacement of the connecting plate 209, so that the force applied by the staff can better act on the frame 1, avoiding excessive tilt of the hand-held rod 202 affecting the transmission of the force.

[0027] When digging holes and planting on some irregular slopes and areas where it is inconvenient for a trolley to travel, the staff holds the handle 203 and uses the cooperation of the hand-held rod 202, the rotating shaft 201 and the first limit plate 4 to flexibly adjust the position and angle of the equipment. The power mechanism 101 is started in the area to be dug, and the power mechanism 101 drives the spiral digging drill bit 102 to rotate to dig a hole on the ground. When digging a hole, two staff members hold the handle 203 and press down. The strong spring 501 buffers the applied force to prevent excessive force from causing the spiral digging drill bit 102 to feed too much and causing the power mechanism 101 to work at a high load. In addition, when the spiral digging drill bit 102 encounters hard stones or pneumatic objects, the strong spring 501 can buffer it to prevent the force from directly acting on the staff's hands and causing the staff to let go, which may cause safety hazards.

[0028] During actual use, the staff can observe the rotation angle of the hand-held rod 202 to avoid contact between the hand-held rod 202 and the second limit plate 403, and then control the force of their downward pressure accordingly to avoid high-load operation of the power mechanism 101.

[0029] The power mechanism 101 may directly adopt a diesel engine, a gasoline engine, an electric motor, etc.

[0030] Example 2: Reference Figure 1-Figure 7 , an automatic digging device for planting trees in landscaping engineering construction is basically the same as Example 1. Furthermore, a second electric telescopic rod 502 is symmetrically fixedly connected to the frame 1, and the output end of the second electric telescopic rod 502 is fixedly connected to the positioning plate 5. The controller 103 controls the contraction of the second electric telescopic rod 502 to adjust the position of the positioning plate 5, thereby adjusting the initial stretched state of the strong spring 501 to adapt to soils of different hardness.

[0031] When it is necessary to adapt to soils of different hardness, the staff controls the contraction of the second electric telescopic rod 502 through the controller 103, adjusts the position of the positioning plate 5, and thus changes the initial stretched state of the strong spring 501. For example, for harder soil, the initial stretching amount of the strong spring 501 can be increased, so that the spiral digging drill bit 102 can obtain greater pressure during operation, while making it easier for the staff to better apply the force.

[0032] A plurality of through holes 205 are provided on the upper side of the handle 203 , and protruding rods 206 are slidably provided in the through holes 205 . A fixing plate 207 is fixedly connected between the plurality of protruding rods 206 , and a first electric telescopic rod 208 is fixedly connected between the fixing plate 207 and the inner wall of the handle 203 .

[0033] When the electronic inclinometer 402 detects that the frame 1 is tilted toward one of the workers, the controller 103 controls the first electric telescopic rod 208 in the handle 203 on the tilted side to extend, and the first electric telescopic rod 208 drives the protruding rod 206 to slide outward. At this time, the worker can feel the protruding rod 206, and the worker can reduce the pressure on the current side accordingly, so that the frame 1 returns to the horizontal state and the first electric telescopic rod 208 retracts, thereby ensuring the verticality of the foundation pit and facilitating coordinated work between the two workers.

[0034] An electronic inclinometer 402 is fixedly connected to the first limit plate 4. When the electronic inclinometer 402 detects that the frame 1 is tilted to one side, the controller 103 controls the second electric telescopic rod 502 on the other side to retract, so that the force of the staff's hand is applied to the tilted end of the frame 1 through the hand-held rod 202 to restore it to a horizontal state.

[0035] In a specific embodiment, when the electronic inclinometer 402 detects that the frame 1 is tilted to one side, the tilt data is transmitted to the controller 103. After analyzing the data, the controller 103 controls the second electric telescopic rod 502 on the other side to retract. The second electric telescopic rod 502 drives the positioning plate 5 to move, thereby changing the tension of the strong spring 501, so that the staff's hand can apply more force to the tilted end of the frame 1 through the handheld rod 202, so that the frame 1 returns to a horizontal state. When it returns to a horizontal turntable, the second electric telescopic rod 502 is reset, so that the spiral digging drill bit 102 can dig a pit vertically, thereby ensuring the quality of the foundation pit.

[0036] Example 3: Reference Figure 1-Figure 7 , an automatic digging device for tree planting in landscaping engineering construction, is basically the same as Example 1, and further, a fixing ring 3 is fixedly connected to the fixing sleeve 2, a sliding rheostat 301 is provided on the fixing ring 3, and a conductive block 304 is fixedly connected to the rotating shaft 201.

[0037] A plurality of indicator lights 401 are provided on the first limiting plate 4 . As the distance the conductive block 304 moves on the sliding rheostat 301 increases, the number of indicator lights 401 that light up red increases.

[0038] When the staff rotates the shaft 201 through the handheld rod 202, the shaft 201 drives the conductive block 304 to slide on the sliding rheostat 301. The position change of the conductive block 304 will change the resistance value of the sliding rheostat 301, thereby generating different electrical signals, and this signal is a weak electrical signal. When the conductive block 304 moves on the sliding rheostat 301, the resistance value of the sliding rheostat 301 changes, and the generated electrical signal is transmitted to the controller 103. The controller 103 controls the on and off of the indicator light 401 according to the change of the electrical signal. The distance moved by the conductive block 304 increases, and the greater the change in the resistance value of the sliding rheostat 301, the controller 103 controls the number of red indicator lights 401 to increase, so that it is easy to observe the force applied by oneself, and prevent excessive force from causing damage to the power mechanism 101 due to high load operation.

[0039] During actual operation, the indicator light 401 is divided into two groups, one side provides an indication of the force applied on the current side, and the other side provides an indication of the force applied by the staff on the other side, so as to facilitate the two staff members to work together and ensure the consistency of the force applied as much as possible.

[0040] The sliding rheostat 301 is provided with a first control area 302 and a second control area 303. When the sliding distance of the conductive block 304 in the first control area 302 of the sliding rheostat 301 increases, the power mechanism 101 drives the spiral digging drill bit 102 to increase its speed. When the conductive block 304 slides on the second control area 303, the speed of the spiral digging drill bit 102 remains unchanged at the maximum speed.

[0041] By automatically regulating the speed of the spiral pit-digging drill bit 102 , the spiral pit-digging drill bit 102 can be prevented from idling at high speed for a long time, thereby saving energy consumption.

[0042] In a specific embodiment, the sliding rheostat 301, the conductive block 304, the first control area 302 and the second control area 303 serve as the entire control mechanism. When the conductive block 304 in the control mechanism moves quickly from the second control area 303 or the first control area 302 to the initial position, and the interval between the multiple conductive blocks 304 moving to the initial position is less than the specified time, the controller 103 controls the power mechanism 101 to drive the spiral digging drill bit 102 to rotate at a specified speed for a specified time to perform soil discharge operations. When the conductive blocks 304 in one or two of the control mechanisms move from the second control area 303 or the first control area 302 to the initial position, the controller 103 controls the power mechanism 101 to stop rotating, thereby realizing accurate detection of the working status. If one of the workers is unable to hold the handheld rod 202 due to an accident, the digging operation is stopped to prevent the still rotating spiral digging drill bit 102 from causing harm to the workers.

[0043] When the conductive block 304 contacts the middle of the second control area 303 of the sliding resistor 301 , the controller 103 controls the power mechanism 101 to stop.

[0044] When the conductive block 304 contacts the middle of the second control area 303 of the sliding rheostat 301, the controller 103 detects that the current signal of the circuit where the conductive block 304 and the sliding rheostat 301 are located reaches the set value, and then the controller 103 controls the power mechanism 101 to stop, thereby effectively preventing the applied force from exceeding the specified value and causing the spiral digging drill bit 102 to speed up too fast in an emergency, thereby effectively preventing damage to the spiral digging drill bit 102 and the power mechanism 101.

[0045] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
