DETAILED DESCRIPTION OF THE EMBODIMENTS
[0026] Please refer to Figures 1-4 ,
[0027] Embodiment 1: A gutter trenching device includes a trenching turntable assembly 1, a plurality of trenching edge teeth 2 are evenly arranged on the trenching turntable assembly 1, and a turntable fastening assembly 3 is further arranged in the middle of the trenching turntable assembly 1.
[0028] The ditch-opening rotary disk assembly 1 includes two mounting disks 101. A number of side slots 102 are evenly formed in one side edge of the mounting disk 101. Two limiting slots 103 are symmetrically formed in the side wall of the side slot 102. Two mounting jacks 104 are symmetrically formed in the inner wall of the side slot 102. Two limiting blocks 105 are symmetrically arranged on both sides of the end of the ditch-opening edge tooth 2.
[0029] The ends of the ditch-opening edge teeth 2 are inserted into the side slots 102 formed on the two mounting disks 101. The limiting blocks 105 are inserted into the limiting slots 103. Connecting screws 106 are inserted into the mounting jacks 104. The ends of the connecting screws 106 penetrate through the ends of the ditch-opening edge teeth 2. A connecting nut 107 is sleeved on the end of the connecting screw 106.
[0030] The rotary disk fastening assembly 3 includes a central connection hole 301 formed in the middle of the mounting disk 101. Four side mounting holes 302 are evenly formed on the side of the central connection hole 301. A side connection plate 303 is arranged on the side of the mounting disk 101. Four fastening screws 304 are evenly arranged on the side of the side connection plate 303. A transmission connection block 305 is arranged in the middle of the side of the side connection plate 303. An installation slot 306 is formed in the transmission connection block 305. The ends of the fastening screws 304 penetrate through the side mounting holes 302.
[0031] A fastening sleeve 310 is sleeved on the end of the fastening screw 304. The end of the transmission connection block 305 penetrates through the central connection hole 301. A transmission main shaft 307 is arranged on the other side of the mounting disk 101. A transmission insertion block 308 is arranged at the end of the transmission main shaft 307. The transmission insertion block 308 is inserted into the installation slot 306. The transmission insertion block 308 and the installation slot 306 are fixedly connected through fixing bolts 309 evenly inserted on the transmission connection block 305.
[0032] Embodiment 2: The difference between this embodiment and Embodiment 1 is that, among them, the inner diameter of the side slot 102 is equal to half of the diameter of the end of the ditch-opening edge tooth 2.
[0033] So that the end of the ditch-opening edge tooth 2 can just be inserted into the slot formed by the two side slots 102.
[0034] Embodiment 3: The difference between this embodiment and Embodiment 1 is that, among them, the middles of the two mounting disks 101 are fixedly connected by fastening sleeves 310 sleeved on the ends of the fastening screws 304.
[0035] So that the connection between the two mounting disks 101 is more firm.
[0036] Embodiment 4: The difference between this embodiment and Embodiment 1 is that, among them, the installation slot 306 is in the shape of a cross-shaped groove, and the transmission insertion block 308 is in the shape of a cross-shaped block.
[0037] The transmission insert block 308 is inserted into the installation slot 306, making the rotation of the transmission connection block 305 more stable.
[0038] In this embodiment, although the existing gutter trencher can complete the gutter operation, most of the cutting teeth on the cutting disc are integrally formed with the cutting disc. When encountering rocks or hard textures in the soil, the cutting teeth are easily bent and damaged, so the entire cutting disc needs to be replaced, which is time-consuming and laborious. Moreover, when a single cutting tooth is damaged, the entire cutting disc needs to be replaced, greatly increasing the user's trenching cost.
[0039] In summary, during specific implementation, when the user uses the trencher for trenching operations, when the trencher operates on a hard ground or touches a rock, the cutting edge teeth 2 installed on the trencher will collide with the rock and be damaged during high-speed rotation. At this time, the user only needs to rotate the connection nut 107 at the corresponding position of the damaged cutting edge teeth 2, and then pull out the connection screw 106 inserted into the installation socket 104 and the end of the cutting edge teeth 2, so as to separate the end of the cutting edge teeth 2 from the installation disc 101.
[0040] The user can quickly and conveniently pull out the damaged cutting edge teeth 2 from the side slot 102, replace them with new cutting edge teeth 2 again, thus completing the replacement of the damaged cutting edge teeth 2. The operation is convenient, the installation is simple, and the replacement can be carried out for a single cutting edge tooth 2, greatly saving the maintenance cost of the workers and being more convenient for the user to use.
[0041] A turntable fastening component 3 is also provided between the two installation discs 101. A fastening screw 304 is provided on the side of the side connection plate 303 in the turntable fastening component 3. The fastening screw 304 can penetrate the side installation hole 302 to fixedly connect the two installation discs 101 again. A transmission connection block 305 is provided in the middle of the side connection plate 303. The end of the transmission connection block 305 can penetrate the middle connection hole 301. Then, a transmission insert block 308 is inserted into the installation slot 306 opened on the transmission connection block 305. The transmission insert block 308 and the transmission connection block 305 are fixed by a fixing bolt 309 inserted by threads. Therefore, when the transmission main shaft 307 provided at the end of the transmission insert block 308 transmits power, it can drive the two installation discs 101 to rotate more stably, making the installation discs 101 drive the cutting edge teeth 2 to perform the trenching operation more stably.
