Description

Technical Field

[0001] This utility model relates to the technical field of trenching and pipe laying machinery, and in particular to a digging plow fixing system for trenching and pipe laying machines. Background Technology

[0002] In projects aimed at improving saline-alkali land, it is necessary to lay sand and gravel underground to create seepage channels, and then bury underground pipes within these channels. Excess saline water from the surface soil and topsoil flows through these channels into the underground pipes and is eventually drained away. Traditional underground pipe installation for saline-alkali land improvement typically involves excavation, support, subgrade construction, pipe laying, and backfilling. During excavation, a power-driven excavator plow is usually used to create trenches. Currently, widely used excavator plows are mounted on trenching machines using plow holders. However, because existing technologies only use pins to connect the plow and plow holder, the fixation is unreliable, resulting in uneven trench bottoms. Utility Model Content

The pin shaft 2 extends and retracts relative to the pin hole provided on the plow holder 1 under the drive of the cylinder rod of the pin cylinder 5, thereby fixing the digging plow 4 and the plow holder 1. A wedge support 9 is provided on the plow holder 1. A wedge cylinder 6 is hinged to the wedge support 9. A front pin shaft 12 is provided on the plow holder 1. The clamping wedge 3 moves up and down under the drive of the cylinder rod of the wedge cylinder 6. The clamping wedge 3 and the front pin shaft 12 cooperate to achieve forward fixation between the digging plow 4 and the plow holder 1.

[0027] refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a rear pin 10 is provided on the plow holder 1, and a clamping fork 11 is provided on the rear pin 10. The clamping fork 11 and the rear pin 10 cooperate to achieve rearward fixation between the digging plow 4 and the plow holder 1. Threaded holes that cooperate with clamping bolts 7 are provided on both sides of the plow holder 1. The clamping bolts 7 are used to fasten and adjust the lateral spacing and lateral fixation between the digging plow 4 and the plow holder 1.

[0028] In this embodiment of the invention, after the digging plow 4 is placed inside the plow holder 1, the control pin cylinder 5 pushes the pin shaft 2 to fix the digging plow 4 on the plow holder 1. At this time, the digging plow 4 can rotate around the pin shaft 2. The clamping fork 11 is installed on the rear pin shaft 10 to restrict the rearward rotation of the digging plow 4. The front wedge cylinder 6 is used to insert the clamping wedge 3 into the gap between the front pin shaft 12 and the digging plow 4 to restrict the forward rotation of the digging plow 4. The front and rear fork tips of the clamping fork 11 have different thicknesses. The vertical positions of the two fork tips of the clamping fork 11 and the clamping wedge 4 are adjusted so that the forward and backward movement of the digging plow 4 is completely restricted, and the lower surface of the digging plow 4 is parallel to the lower surface of the plow holder 1. The left and right position of the digging plow 4 is adjusted by the left and right clamping bolts 7 so that the digging plow 4 is located in the middle of the plow holder 1, and the displacement in the left and right directions is completely restricted by the clamping bolts 7.

[0029] This utility model provides a digging plow fixing system for a trenching and pipe-laying machine. The digging plow fixing system includes a plow holder and a digging plow fixed to the plow holder by a pin and a clamping wedge. The pin is hinged to the cylinder rod of a pin cylinder, and the clamping wedge is hinged to the cylinder rod of a wedge cylinder. Both sides of the plow holder are provided with clamping bolts. The pin and clamping wedge, together with the clamping bolts, achieve reliable fixing between the digging plow and the plow holder, avoiding uneven trench bottoms caused by loosening between the digging plow and the plow holder.

[0030] refer to Figure 4 and Figure 5As shown, the digging plow used in this embodiment of the present invention includes a digging plow body 401 and wing plates 402 disposed on both sides of the digging plow body 401. The wing plates 402 are set as inclined slopes or planes facing the direction of the digging plow's forward movement. The two sides of the digging plow body 401 are parallel, and the width between the two sides of the digging plow is between 30mm and 300mm. That is, the corresponding two sides of the digging plow body 401 in this embodiment of the present invention have a parallel structure, and the width between the two sides is 30mm to 300mm. In other words, the digging plow for trenching and pipe laying in this embodiment of the present invention adds two wing plates 402 to the narrow digging plow body. Therefore, during the digging process, the wing plates 402 can provide support to the digging plow body during the trenching process, improving the stability and reliability of the digging plow during the trenching process, and thus improving the flatness and uniformity of the bottom of the excavated trench.

[0031] refer to Figure 4 and Figure 5 As shown, a bottom wear-resistant plate 403 is provided below the digging plow body 401, and wing plates 402 are fixed to both sides of the bottom wear-resistant plate 403. Of course, the bottom wear-resistant plate 403 may not be provided below the digging plow body 401, but preferably, by providing a bottom wear-resistant plate 403 below the digging plow body 401, the wear resistance of the bottom of the digging plow body 401 can be improved, the wear during the use of the digging plow can be reduced, and the service life of the digging plow can be increased.

[0032] refer to Figure 4 As shown, in another possible implementation, regardless of whether the bottom wear-resistant plate 403 is provided at the bottom of the digging plow body 401, the wing plate 402 can be fixed on both sides of the digging plow body, and the wing plate 402 is parallel to the lower surface of the digging plow body 401.

[0033] In another possible implementation, the fins 402 are fixed on both sides of the digging plow body 401, and the angle between the fins 2 and the lower surface of the digging plow body 1 is less than 45°. That is, the fins 402 can be tilted towards or away from the direction of the digging plow's movement on both sides of the digging plow body 401. This tilted arrangement can better provide support for the digging plow body during the digging process, further improving the stability and reliability of the digging plow during the trenching process, and thus improving the flatness and uniformity of the bottom of the excavated trench.

[0034] refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown in the embodiment of this utility model, a plow head 404 is provided at the front of the digging plow body 401. The bottom of the plow head 404 is in the same plane as or lower than the lower surface of the bottom wear-resistant plate 403. A top wear-resistant plate 405 is provided on the digging plow body 401. The angle between the front surface of the plow head 404 and the top wear-resistant plate 405 is less than 30°, and the angle between the top wear-resistant plate 405 and the bottom wear-resistant plate 403 is greater than 30° and less than 60°.

[0035] By setting a plow head 404 in front of the digging plow body 401, the plow head 404 can reduce the difficulty of trenching and improve the trenching efficiency of the digging plow during the digging process; wear-resistant plates are set in front of and below the digging plow body, that is, by setting a top wear-resistant plate 405 and a bottom wear-resistant plate 403, the wear of the digging plow body during use is reduced and the service life of the digging plow is improved.
