[0023] The technical solution of the present utility model is further described in detail below with reference to the accompanying drawings.

[0024] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0025] Example 1

[0026] Reference Figures 1 to 6 , which is the first embodiment of the present utility model, provides a TRD cutting device with a water jet head. The TRD cutting device with a water jet head includes a main body assembly 100, including a cutting box 101, a chain 102, a cutting knife 103 and a support member 104. The chain 102 is located in the cutting box 101, the cutting knife 103 is fixed to one side of the chain 102, and the support member 104 is arranged in the cutting box 101.

[0027] The cutting box 101 is used to support the chain 102 and the support member 104 . The chain 102 is used to drive the cutting blade 103 to cut the soil. The support member 104 is used to support the chain 102 .

[0028] The adjusting assembly 200 is arranged in the cutting box 101 and includes a conveying member 201, an adjusting member 202 and a breaking member 203. The conveying member 201 is arranged in the cutting box 101, the adjusting member 202 is located on the conveying member 201, and the breaking member 203 is arranged on one side of the cutting box 101.

[0029] The conveying part 201 is used to transport water and clean the cutting knife 103 at the same time to prevent the tool from being adhered to silt and reduce the soil cutting speed. The adjusting part 202 can adjust the cleaning force of the cutting knife 103 and determine whether a water jet is needed to cut the soil. The soil breaking part 203 is used to cut the soil to improve construction efficiency.

[0030] Specifically, the support member 104 includes a support shaft 104a and a support gear 104b. The support shaft 104a slides in the cutting box 101, and the support gear 104b is rotatably connected to the surface of the support shaft 104a.

[0031] The support shaft 104 a is used to support the support gear 104 b , and the support gear 104 b is engaged with the chain 102 .

[0032] Specifically, the support member 104 also includes an extrusion block 104c, a positioning column 104d and a compression spring 104e. The extrusion block 104c slides in the cutting box 101, the positioning column 104d is fixed to one side of the extrusion block 104c, and the two ends of the compression spring 104e are respectively fixed to the inner wall of the cutting box 101 and one side of the extrusion block 104c.

[0033] The compression spring 104e is in a compressed state and is used to push the extrusion block 104c, so that the extrusion block 104c squeezes the support shaft 104a, thereby positioning the support gear 104b. When encountering a stratum with relatively strong soil strength, the downward movement of the support gear 104b will be hindered, causing the compression spring 104e to be further compressed. At this time, the positioning column 104d approaches the inner wall of the cutting box 101. When the end of the positioning column 104d moves to the inner wall of the cutting box 101, the support gear 104b no longer further squeezes the compression spring 104e.

[0034] Example 2

[0035] Reference Figures 1 to 6 , which is the second embodiment of the present utility model, and this embodiment is based on the previous embodiment.

[0036] Specifically, the conveying member 201 includes a water pipe 201a and a conversion shell 201b. The water pipe 201a is fixed in the cutting box 101, and the conversion shell 201b is fixed to the end of the water pipe 201a.

[0037] The water pipe 201a is used to transport water into the conversion shell 201b, and the water can be used to clean the tool or cut the soil through the conversion shell 201b.

[0038] Specifically, the conveying member 201 further includes a connecting tube 201c and a compression tube 201d. The connecting tube 201c is fixed in the cutting box 101, and the compression tube 201d is fixed to the end of the connecting tube 201c.

[0039] The connecting pipe 201c is used to transport the water in the conversion housing 201b to the compression pipe 201d, so that the water is compressed by the compression pipe 201d.

[0040] Specifically, the conveying member 201 further includes a nozzle 201 e , which is fixed to one side of the compression tube 201 d and is located on one side of the chain 102 .

[0041] There are multiple nozzles 201e, and the compressed water in the compression tube 201d can be sprayed out through the nozzles 201e, thereby cleaning the chain 102 and the cutting knife 103.

[0042] Specifically, the conveying member 201 further includes a water pipe 201f, and the water pipe 201f is fixed to the surface of the conversion shell 201b.

[0043] The water pipe 201f is used to transport the water in the conversion shell 201b to the earth-breaking member 203 for cutting the soil and improving the construction efficiency.

[0044] Specifically, the adjusting member 202 includes an adjusting wheel 202a and a driving shaft 202b. The adjusting wheel 202a is rotatably connected to the conversion shell 201b, and the driving shaft 202b is fixed to one side of the adjusting wheel 202a. A water inlet groove U, a water delivery groove V and a water outlet groove W are opened in the adjusting wheel 202a.

[0045] The regulating wheel 202a is used to adjust the flow direction of the water body, and the driving shaft 202b is used to drive the regulating wheel 202a to rotate. In the current state shown in the figure, the water inlet trough U and the water pipe 201a are partially connected. At this time, the flow rate of the water pipe 201a entering the water inlet trough U is small. Through the transportation of the water trough V, the water body flows into the water outlet trough W. At this time, the water outlet trough W and the connecting pipe 201c are completely connected, and the water outlet trough W and the water pipe 201f are not yet connected, so that the water body in the water outlet trough W is transported to the compression pipe 201d through the connecting pipe 201c, and then the chain 102 and the cutting knife 103 are cleaned through the nozzle 201e.

[0046] Specifically, the adjusting member 202 further includes an adjusting gear 202c and a gear rod 202d. The adjusting gear 202c is fixed to the surface of the driving shaft 202b, and the gear rod 202d is fixed to one side of the extrusion block 104c.

[0047] When encountering a stratum with relatively strong soil strength, the downward movement of the support gear 104b will be blocked, causing the compression spring 104e to be further compressed. At this time, the extrusion block 104c will drive the gear rod 202d to move upward, thereby driving the adjusting gear 202c to rotate, so that the adjusting gear 202c drives the adjusting wheel 202a to rotate through the drive shaft 202b. As the adjusting wheel 202a rotates, the water inlet trough U and the water pipe 201a are fully connected. At this time, the flow rate of the water pipe 201a entering the water inlet trough U is large, and, as the adjusting wheel 202a rotates, the water outlet trough W begins to communicate with the water pipe 201f, so that the water can flow to the earth-breaking piece 203 through the water pipe 201f, thereby cutting the soil and improving construction efficiency.

[0048] If the soil is strong, the compression spring 104e will be further compressed, and the adjusting wheel 202a will be further rotated. At this time, the water outlet trough W and the connecting pipe 201c are disconnected, and the water in the water outlet trough W completely flows into the water guide pipe 201f, so that the earth-breaking piece 203 obtains greater water pressure, thereby better cutting the soil and improving construction efficiency.

[0049] When the soil strength begins to weaken, under the elastic force of the compression spring 104e, the gear rod 202d drives the adjusting gear 202c to reset, thereby resetting the adjusting wheel 202a, allowing water to flow into the connecting pipe 201c again to clean the cutter.

[0050] Specifically, the earth-breaking component 203 includes a water outlet pipe 203a, a rotating water jet 203b and a stopper 203c. The water outlet pipe 203a is fixed to the end of the water pipe 201f, the rotating water jet 203b is fixed to one side of the water outlet pipe 203a, and the stopper 203c is fixed to one side of the cutting box 101.

[0051] The water outlet pipe 203a is connected to the rotating water jet 203b. The rotating water jet 203b is a prior art. When water is supplied to the rotating water jet 203b, the rotating water jet 203b will rotate, thereby better cutting the soil. The block 203c is used to protect the rotating water jet 203b to prevent the soil and other debris on both sides from blocking the movement of the rotating water jet 203b.

[0052] During use, when encountering a stratum with relatively strong soil strength, the downward movement of the support gear 104b will be blocked, causing the compression spring 104e to be further compressed. At this time, the extrusion block 104c will drive the gear rod 202d to move upward, thereby driving the adjusting gear 202c to rotate, so that the adjusting gear 202c drives the adjusting wheel 202a to rotate through the drive shaft 202b. As the adjusting wheel 202a rotates, the water inlet trough U and the water pipe 201a are fully connected. At this time, the flow rate of the water pipe 201a entering the water inlet trough U is large, and, as the adjusting wheel 202a rotates, the water outlet trough W begins to communicate with the water pipe 201f, so that the water can flow to the earth-breaking piece 203 through the water pipe 201f, thereby cutting the soil and improving construction efficiency.

[0053] If the soil is strong, the compression spring 104e will be further compressed, and the adjusting wheel 202a will be further rotated. At this time, the water outlet trough W and the connecting pipe 201c are disconnected, and the water in the water outlet trough W completely flows into the water guide pipe 201f, so that the earth-breaking piece 203 obtains greater water pressure, thereby better cutting the soil and improving construction efficiency.

[0054] When the soil strength begins to weaken, under the elastic force of the compression spring 104e, the gear rod 202d drives the adjusting gear 202c to reset, thereby resetting the adjusting wheel 202a, allowing water to flow into the connecting pipe 201c again to clean the cutter.
