[0011] In the figure: 1. lower stopper; 2. support frame; 3. linear rail; 4. roller; 5. travel switch; 6. spiral trenching tool; 7. connecting bracket; 8. upper stopper; 9. slide block; 10. oil cylinder; 11. electromagnetic reversing valve. DETAILED DESCRIPTION
[0012] The utility model is further described in detail below in conjunction with the accompanying drawings.
[0013] The utility model is a precise spiral ditching device, comprising a spiral ditching tool 6, a support frame 2 and a cylinder 10. A linear rail 3 and a slider 9 are provided on one side of the support frame 2, and a cylinder 10 is provided on the other side. The slider 9 is connected to an "L"-shaped connecting bracket 7, and the spiral ditching tool 6 is provided on the connecting bracket 7 and is connected to the telescopic rod of the cylinder 10.
[0014] An upper stop iron 8 and a lower stop iron 1 are respectively provided above and below the support frame 2, and a travel switch 5 is provided between the upper stop iron 8 and the lower stop iron 1. The travel switch 5 is arranged on the spiral ditching machine 6. The oil inlet and outlet ports of the oil cylinder 10 are connected to the electromagnetic reversing valve 11 at the same time, and the travel switch 5 is connected to the processor, and the processor sends a signal to the electromagnetic reversing valve 11 to control the extension and retraction of the oil cylinder 10.
[0015] The travel switch 5 is arranged on the spiral ditching machine 6 in the form of a rotating pin, and can rotate, and the travel switch 5 top is provided with a roller 4. Its roller 4 can be a bearing.
[0016] The specific working principle is as follows:
[0017] When the device starts working, the cylinder 10 drives the spiral trenching tool 6 to move downward to open the trench. When the travel switch 5 hits the lower stop iron 1, it rotates and sends a signal to the processor to start timing (the user can adjust the timing time according to needs). When the time is reached, the processor sends a signal to the electromagnetic reversing valve 11 to control the cylinder 10 to work in the reverse direction. At this time, the spiral trenching tool 6 moves upward. When the travel switch 5 hits the upper stop iron 8, it rotates and sends a signal to the processor to start timing (the user can adjust the timing time according to needs). When the time is reached, the processor sends a signal to the electromagnetic reversing valve 11 to control the cylinder 10 to work in the reverse direction and repeat the above work.
