Description

Technical Field

[0001] The invention belongs to the technical field of planting trench excavation, and in particular relates to a trench excavation device for municipal garden greening construction. Background Art

[0002] Gardening and landscaping is an important part of urban construction and ecological environment construction. It not only beautifies the environment and improves the quality of urban landscape, but also has ecological functions such as regulating climate, purifying air, conserving water resources, and reducing noise. Through carefully designed and maintained garden landscapes, it can provide people with a comfortable and pleasant leisure space, allowing people to get closer to nature and enjoy life. During the construction of gardening and landscaping, trenching devices are usually used to dig trenches on the ground to provide suitable space and conditions for plant planting. For example, a gardening and landscaping trenching device proposed in the authorization announcement number CN220755455U improves the convenience of trenching when planting plants and effectively reduces the difficulty of trenching with a plow.

[0003] The existing principle of ditching devices for greening construction has the following problems when in use.

[0004] In southern my country, due to the humid climate and abundant rainfall, a relatively deep clay layer has formed in most areas. When the trenching device is used to dig trenches in the clay layer, the clay will adhere to the plow blade, so that the plow blade will bear greater resistance during the movement, which not only reduces the working efficiency of the trenching device, but also makes the trenching device run poorly, resulting in uneven trenching, affecting the trenching quality, and the trenching device needs to consume more energy to move forward, which also increases the energy consumption of the device;

[0005] In addition, during the movement of the furrowing device, the plow blade may come into contact with stones or tree roots inside the soil. When the stones and tree roots are large and the plow blade is still moving while in contact with the stones or tree roots, the plow blade may be damaged, curled or deformed due to the impact, requiring the operator to pause the device for a long time to replace the plow blade.

[0006] Therefore, a ditching device for municipal landscaping construction is proposed to solve the above problems. Summary of the invention

[0035] A handle 43 is fixedly connected to the upper side wall of the moving frame 1, and a control button 44 is fixedly connected to the upper side wall of the handle 43. The control button 44 is electrically connected to the PLC controller, which facilitates the operator to control the moving direction of the device and can control the device to work.

[0036] An observation window 45 is provided on the surface of the water storage tank 17, and a depth scale is provided on the surface of the observation window 45, which facilitates the operator to observe the water volume in the water storage tank 17.

[0037] The operation principle of the present invention is described as follows: Move the trench digging device to the construction site of municipal landscaping, and place the trench digging device in place. Then, the operator holds the handle 43 by hand and presses the control button 44. The control button 44 transmits an electrical signal to the PLC controller. After receiving the electrical signal, the PLC controller first controls the electric drive roller 2 and the first electric push rod 3 to work simultaneously. The electric drive roller 2 drives the device to move in the set direction, and the first electric push rod 3 drives the induction cylinder 111, the vertical pipe 4 and the plow blade 5 to move downward together, so that the plow blade 5 inserts into the ground to a certain depth, and the plow blade 5 moves forward under the drive of the electric drive roller 2 to perform trench digging operation on the ground;

[0038] When the position of the ditching operation is in a clay area, when the plow blade 5 ditches on the ground, the resistance it encounters will increase compared to sandy soil. The plow blade 5 drives the induction block 112 and the conductive block 12 to move leftward through the vertical pipe 4, causing the induction block 112 to squeeze the spring on the left side until the elastic force of the spring is the same as the resistance of the plow blade 5, and then the induction block 112 will stop moving. At this time, the induction block 112 will drive the conductive block 12 to contact the induction plate 13. The conductive block 12 is electrically connected to the storage battery, and the induction plate 13 is electrically connected to the PLC controller. After the conductive block 12 and the induction plate 13 are in contact, an electrical signal will be sent to the PLC controller. After receiving this electrical signal, the PLC controller will control the second electric push rod 151 to work reciprocally after a 30-second delay (the soil humidity detection is completed earlier than the water spraying on the surface of the plow blade 5 to avoid affecting the subsequent measurement of soil humidity). The second electric push rod 151 drives the piston plate 16 to move reciprocally in the water supply tank 152. When the piston plate 16 moves leftward driven by the second electric push rod 151, the air pressure inside the water supply tank 152 will decrease. Under the action of negative pressure, the water in the water storage tank 17 will be transported into the water supply tank 152 through the elbow pipe 18 and the one-way valve 20 for storage. When the piston plate 16 moves rightward, the water pressure inside the water supply tank 152 will increase. Under the action of the two one-way valves 20, the water inside the water supply tank 152 will be transported into the interior of the induction block 112 through the hose 19. The induction block 112 is of a hollow structure and is connected to the vertical pipe 4, so that water can be transported to the interior of the plow blade 5 through the induction block 112 and the vertical pipe 4. The interior of the plow blade 5 is of a hollow structure. When water is transported into the plow blade 5, the internal pressure of the plow blade 5 will increase, filling a certain part of the interior of the plow blade 5, so that the hollow plow blade 5 has a certain resistance to pressure, avoiding the deformation of the plow blade 5. And under the action of pressure, the water will pass through the water outlet holes 6 and push open the water baffle 8 (the water baffle 8 is aligned with the surface of the plow blade 5 to avoid the problem that the water baffle 8 protruding from the surface of the plow blade 5 will increase the resistance of the plow blade 5. And except for the clay on the surface of the uppermost water baffle 8 that is not convenient to clean, the clay in other parts can be washed down by the water flow), so that the water flows out from the surface of the plow blade 5, thereby lubricating the clay attached to the surface of the plow blade 5, reducing the adhesion force between the clay and the plow blade 5, and avoiding the problems that the adhesion of the clay to the surface of the plow blade 5 will increase the resistance of the plow blade 5, reduce the ditching work efficiency, affect the ditching quality and increase the energy consumption of the device. When there is no water flowing out, the water baffle 8 will rotate towards the plow blade 5 under the thrust of the soil and be fixed by the adsorption of the magnet 10;

[0039] When the plow blade 5 contacts large stones and tree roots in the soil during movement, the large stones and tree roots will not be pushed. After the plow blade 5 contacts the stones and tree roots, it will receive a large reaction force. The plow blade 5 will drive the vertical pipe 4, the induction block 112 and the conductive block 12 to move quickly to the left. While reducing the impact force on the plow blade 5, it will also cause the induction block 112 to quickly squeeze the airbag 23 on the left side, which can buffer the plow blade 5. The airbag 23 will transport a large amount of gas into the trigger box 221 through the air supply pipe 24 in a short time. Only a small amount of gas will be discharged through the small hole 25, so that there will be a large air pressure on the left side of the airtight block 222 in a short time, pushing the airtight block 222 to drive the trigger frame 27 to move to the right, so that the trigger frame 27 contacts the trigger plate 28. The trigger frame 27 is electrically connected to the storage battery, and the trigger plate 28 is electrically connected to the PLC controller. When the trigger frame 27 contacts the trigger plate 28, an electrical signal will be sent to the PLC controller. After receiving the electrical signal, the PLC controller will immediately control the electric drive roller 2 to stop moving, and then control the buzzer on the moving frame 1 to work, reminding the operator that the trenching device needs to move in the reverse direction. Subsequently, the operator can control the electric drive roller 2 to rotate in the reverse direction through an external switch, so that the plow blade 5 is separated from the stones and tree roots, avoiding the problem that the plow blade 5 continues to move and collide with the stones and tree roots, resulting in damage, edge rolling or deformation of the plow blade 5;

[0040] When the trenching device is trenching, the PLC controller will control the third electric push rod 291 to work. The third electric push rod 291 drives the sampling cylinder 30 to move downward, so that the sampling cylinder 30 contacts the soil in the trench and extracts a part of the soil sample into the sampling cylinder 30. After the third electric push rod 291 drives the sampling cylinder 30 to move downward for five seconds, the third electric push rod 291 will drive the sampling cylinder 30 to move upward to return to its original position. After thirty seconds, the water supply component 15 will start to work, which will not affect the humidity of the soil in the sampling cylinder 30. The humidity of the soil is detected by the electronic hygrometer 34 inside the sampling cylinder 30. When the electronic hygrometer 34 detects that the humidity in the soil is low, the electronic hygrometer 34 will send an electrical signal to the PLC controller, so that the PLC controller controls the water pump 35 to work. The water pump 35 continuously sprays the water in the water storage tank 17 through the spray pipe 36 and the spray head 37, so that the trenching device trenches in the front while spraying water to moisturize the trench that has been opened in the back, keeping the soil with a certain amount of moisture and creating favorable conditions for the subsequent planting of plants.

[0041] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
