Meanwhile, the plurality of sensors 14 arranged on the trenching machine can obtain related parameter information such as the humidity of the soil in the trenching area, the hardness of the soil, and the viscosity of the soil, and the database center can obtain environmental information such as temperature information, precipitation information, and humidity information from the local meteorological bureau, and upload the information to the controller 12, and the controller 12 can comprehensively analyze the related parameter information and the environmental information to determine whether the running speed of the chain trenching blade 1303 of the trenching machine 1 is within the predetermined requirement, and generate corresponding adjustment instructions to adjust the running speed of the chain trenching blade 1303 according to the determination result, so that the running speed of the chain trenching blade 1303 can be adjusted in time according to the soil condition of the trenching area, thereby ensuring the progress of trenching and reducing the damage of the blade.

[0042] The method for adjusting the running speed of the slotting component 13 according to the analysis result by the controller 12 is as follows:

[0043] Firstly, the obtained relevant parameter information and environment information are comprehensively analyzed. Specifically, the soil humidity value S RH , the hardness value S H and the viscosity value S CY of the soil obtained by each sensor 14 are acquired, so as to obtain the soil influence coefficient S through the formula g . Generally, the smaller the soil humidity, the higher the hardness value of the soil or the higher the viscosity value of the soil, the greater the influence on the slotting blade, so the soil influence coefficient S g is obtained through the formula , and the greater the value, the greater the influence on the slotting efficiency; then the average precipitation E W , the average humidity E RH and the average temperature E T of the database center in the past month are acquired, so as to obtain the environment influence coefficient E g through the formula . The less the average precipitation of a certain area in a month or the smaller the average humidity, the greater the influence of the soil in the corresponding state on the slotting blade speed, and the formula This can represent the change in the difference between the acquired temperature and the preset standard temperature within the system. The smaller the change, the smaller the impact on the blade's running speed; conversely, the larger the change, the greater the impact on the blade's running speed, and consequently, the greater the impact on grooving efficiency. Therefore, the formula... Obtain the environmental impact factor E g The larger the value, the greater the impact on trenching efficiency; therefore, to more accurately assess soil conditions, a formula is finally used. A comprehensive analysis is performed to obtain the adjustment judgment value G. Then, the obtained adjustment judgment value G is compared with the system's preset adjustment judgment value range [G1, G2]. When G∈(G2, +∞), it indicates that the influence value is relatively large. In order to ensure the grooving efficiency, the running speed of the chain grooving piece 1303 needs to be increased accordingly, and an increase command is generated. Conversely, when G∈(0, G1), it indicates that the influence value is relatively small. The set running speed is sufficient to ensure normal grooving efficiency. In order to reduce tool wear, the running speed can be appropriately reduced without affecting the grooving efficiency, and a decrease command is generated. When G∈[G1, G2], no adjustment is required, and the current speed can be maintained, and a hold command is generated.

[0044] After obtaining the adjustment command through the above method, the controller 12 then controls the running speed of the chain slotting piece 1303 on the slotting component 13 accordingly. Specifically, when the command is determined to be an adjustment command, the speed is adjusted using the formula... Increase the running speed of the slotted component 13 to V + When the instruction is determined to be lower, it is processed using the formula. Reduce the running speed of the slotted component 13 to V. - When the instruction is determined to be hold, the current running speed is maintained; from the formula It can be seen that the more the adjustment value G exceeds the threshold G2, the greater the increase in operating speed is required. However, each tool also has a certain critical speed and cannot be increased indefinitely. Infinitely increasing the speed would severely damage the tool quality. Therefore, a maximum operating speed that can be increased within the system is set to limit the speed and protect the tool. The adjustment of the operating speed is not only related to the soil conditions but also to the depth and width of the groove. Generally speaking, the deeper and wider the groove, the greater the cutting resistance of the tool and the greater the impact on the operating speed. Therefore, the deeper the groove depth L and the larger the width K, the greater the increase in operating speed is required. Similarly, from the formula... It can be seen that when the adjustment judgment value G is smaller, the smaller the influence on the tool running speed, the more the corresponding adjustable low speed, and the speed cannot be infinitely reduced, if reduced too much, it will affect the normal slotting efficiency, therefore, a maximum running speed allowed to be reduced in the system is set to limit and ensure the slotting efficiency. Thus, the soil information obtained and the historical information of the region can be comprehensively analyzed to dynamically adjust the running speed of the trencher 1, which can ensure the slotting efficiency, reduce the damage of the blade, and reasonably save resources.

[0045] It should be noted that the calculation of the above formula is only a mutual calculation in numerical value, the conversion coefficient β, the slotting depth reference value ΔL, the slotting width reference value ΔK and the adjustment judgment value interval [G1, G2] can be determined according to historical data combined with the results of test simulation data, and the standard temperature in the system The preset weight coefficients τ1 and τ2 can be obtained according to empirical data, and the maximum running speed allowed to be increased in the system The maximum running speed allowed to be reduced in the system The maximum running speed allowed to be increased in the system can be determined according to the historical running data of the tool of the notification type, which will not be described too much here.

[0046] The trencher of the present application can greatly reduce the construction steps and improve the progress of the whole project, and the trenching and laying integrated equipment of the present application can adapt to different sizes of trenching and different sizes of pipe construction, so that the equipment has better economic benefits. The plurality of sensors provided on the trencher of the present application can obtain related parameter information such as the humidity, hardness and viscosity of the soil in the trenching area, and the database center can obtain temperature information, precipitation information and humidity information from the local meteorological bureau, and upload them to the controller. The controller can comprehensively analyze the related parameter information and the environmental information, judge whether the running speed of the chain trenching blade of the trencher meets the requirement of slotting efficiency, and generate corresponding adjustment instructions according to the judgment result to adjust the running speed of the chain trenching blade. Thus, the running speed of the trencher can be adjusted in time according to the soil condition of the trenching area, so as to ensure the slotting efficiency and reduce the damage of the blade.
