Description

Technical Field

[0001] The utility model belongs to the technical field of trenching machines, in particular to a novel disc type trenching machine. Background Art

[0002] At present, when laying cables, trenching operations are usually performed using trenchers. Specifically, when in use, the trencher is rear-mounted and suspended on a power platform of a tractor, and the trencher can be raised and lowered in a circular motion by a lifting mechanism arranged on the power platform, and the trencher can be driven to operate by a power transmission mechanism arranged on the power platform, so that when the tractor is moving forward, the trencher can open a trench on the ground to facilitate the burying of the cable; and since the location where the cable is buried underground is usually at the curb, the existing trencher is usually an eccentric trencher, that is, when in operation, the tractor walks on the road, and the trenching mechanism on the eccentric trencher is located on one side of the tractor, so that when the trencher is running, a trench can be opened on the curb.

[0003] In the prior art, when constructing an expressway, it is necessary to bury cables in the isolation zone in the middle of the expressway. However, the isolation zone in the middle of the expressway is a pit before construction is completed, that is, there is a certain height difference between the bottom of the pit and the road surface of the expressway. Therefore, when an eccentric trencher is used to open a trench at the bottom of the pit, although the lifting mechanism on the tractor can realize the lifting and lowering adjustment of the trencher, the adjustable height range is not sufficient to overcome the height difference. Therefore, the tractor and the eccentric trencher must be located in the pit to avoid the height difference from affecting the trenching operation. However, since the trenching mechanism on the eccentric trencher is located on one side of the tractor during operation, the width space required for the eccentric trencher during operation is greater than the pit width of the pit. Therefore, the existing trencher is not suitable for opening trenches in the isolation zone in the middle of the expressway, and there are still defects and shortcomings. Utility Model Content

DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solution and beneficial effects of the present invention clearer, the implementation mode of the present invention is further described in detail below with reference to the accompanying drawings.

[0027] like Figures 1 to 7 As shown, the utility model provides a novel disc-type trencher, including a horizontally arranged chassis 3, one end of which is equipped with a vertically distributed suspension frame 6, and the end of the chassis 3 is also equipped with a gearbox 7 with an input shaft and an output shaft. Specifically, the chassis 3, the suspension frame 6 and the gearbox 7 are all prior arts. When in use, the utility model utilizes the suspension frame 6 to be rear-mounted on the power platform of the tractor through a three-point suspension, and the trencher can be lifted and lowered in a circular motion by a lifting mechanism arranged on the power platform, and the power input of the gearbox 7 can be realized by a power transmission mechanism arranged on the power platform.

[0028] In addition, two vertically arranged first bearing seats 1 are installed at one end of the base frame 3 away from the suspension frame 6, and the two first bearing seats 1 are symmetrically distributed on both sides of the base frame 3, and the inner side of each first bearing seat 1 is rotatably connected with a horizontally distributed first rotating shaft 8, one of the first rotating shafts 8 is transmission-connected to the output shaft of the gearbox 7 via a transmission device 5, and a disc 9 coaxially arranged with the first rotating shaft 8 is detachably fixedly connected between the ends of the two first rotating shafts 8 away from the first bearing seats 1 via a flange and bolts, the disc 9 is located in the middle position of the base frame 3, the bottom of the disc 9 is located outside the base frame 3, and the outer periphery of the disc 9 is fixedly connected with a plurality of grooving teeth 10 equidistantly distributed along the circumference of the disc 9. Specifically, the first A rotating shaft 8 can be rotated under the drive of the gearbox 7 and the transmission device 5, and the first rotating shaft 8 can drive the disc 9 to rotate during the rotation process, so that when the tractor moves forward, the ditching teeth 10 can open a groove under the drive of the disc 9; and because the disc 9 is located in the middle position of the chassis 3, when the ditching teeth 10 are used to ditch under the drive of the disc 9 and the tractor, they can be located in the middle position of the tractor, thereby reducing the width space required for the ditching machine during operation to adapt to the pit width of the pit, that is, when the utility model is used, it can be located in the pit together with the tractor to perform ditching operations, that is, the utility model can be suitable for opening grooves at the isolation belt position located in the middle of the highway.

[0029] In order to improve the stability of the trenching teeth 10 during the trenching process, Figures 1 to 3 and Figures 5 to 7 As shown, a vertically distributed support rod 11 is fixedly connected to the outer side of each first bearing seat 1, and the bottom end of each support rod 11 is fixedly connected to the base frame 3; a cross bar 12 is fixedly connected between the top ends of the two support rods 11, and a horizontally distributed connecting rod 13 is arranged between each support rod 11 and the suspension frame 6, one end of the connecting rod 13 is fixedly connected to the support rod 11, and the other end of the connecting rod 13 is detachably fixedly connected to the suspension frame 6. Specifically, a gate-shaped frame can be formed between the two support rods 11 and the cross bar 12, and by installing the connecting rod 13 between the gate-shaped frame and the suspension frame 6, the structural stability of the trencher can be improved, thereby improving the stability of the trenching teeth 10 during the trenching process.

[0030] The specific method of detachably fixing the connecting rod 13 to the suspension bracket 6 is as follows: Figures 1 to 3 and Figures 5 to 7As shown, one end of each connecting rod 13 close to the suspension bracket 6 is fixedly connected to a vertically distributed first connecting plate 14, the first connecting plates 14 are respectively located on the inner side of the connecting rod 13, and the four corners of the first connecting plate 14 are provided with horizontally arranged strip through holes 141, and both sides of the suspension bracket 6 are fixedly connected to vertically distributed second connecting plates 15, and the four corners of the second connecting plate 15 are connected to the strip through holes 141 respectively through horizontally arranged first bolt connection pairs 16, specifically, the first bolt connection pair 16 includes a first connecting bolt 161 and a first locking nut 162. When in use, when the connecting rod 13 is connected to the suspension bracket 6, the screw end of the first connecting bolt 161 can pass through the strip through hole 161 after passing through the second connecting plate 15. 41 penetrates the first connecting plate 14, then the first locking nut 162 is sleeved on the first connecting bolt 161, and the heads of the first locking nut 162 and the first connecting bolt 161 are respectively abutted against the first connecting plate 14 and the second connecting plate 15, so that the connecting rod 13 can be connected to the suspension bracket 6; in addition, since the ditching teeth 10 first enter the ground and then gradually go deeper when ditching, the disc 9 will apply a force toward the position of the suspension bracket 6 to the gate-shaped frame, and in order to avoid the force causing serious deformation of the gate-shaped frame, a strip through hole 141 is provided in the first connecting plate 14, so that when the disc 9 applies a force toward the position of the suspension bracket 6 to the gate-shaped frame, the gate-shaped frame can have a movable space that can tilt forward.

[0031] In order to facilitate the adjustment of the range of activities of the gate-shaped frame that can be tilted forward, each second connection 15 is fixedly connected to a fixing block 17 located outside the connecting rod 13, and each fixing block 17 is respectively threadedly connected to a tightening bolt 18 that penetrates the fixing block 17 and is coaxially arranged with the connecting rod 13. Specifically, by rotating the tightening bolt 18, the distance between the screw end of the tightening bolt 18 and the connecting rod 13 can be adjusted, thereby facilitating the adjustment of the range of activities of the gate-shaped frame that can be tilted forward.

[0032] Since the trenching teeth 10 will dig out soil during the trenching process, in order to prevent the soil from splashing around, Figure 1 , Figure 3 and Figures 5 to 7 As shown, a protective cover 19 is provided on the disc 9. The protective cover 19 includes two arc-shaped protective plates 191 arranged opposite to each other. The opposite sides of the two protective plates 191 are connected to form a Figure 7 The V-shaped structure shown in the figure has one end of the two protective plates 191 connected to the cross bar 12 via a connecting frame 192, and the other end of the two protective plates 191 is connected to the base frame 3 via another connecting frame 192, so that the structural stability of the protective cover 19 can be ensured. Specifically, when in use, when the trenching teeth 10 are in the process of trenching, the V-shaped protective cover 19 can prevent mud from splashing around.

[0033] Further, such as Figure 1 and Figures 3 to 6 As shown, a vertically distributed and height-adjustable depth wheel device 4 is installed on one side of each first bearing seat 1 away from the suspension frame 6, and each set of depth limiting wheel devices 4 is located outside the base frame 3. Specifically, when the tractor is moving forward, the depth limiting wheel device 4 can move along the ground, thereby improving the stability of the base frame 3 during movement; in addition, since the height position of the depth limiting wheel device 4 is adjustable, when in use, it can cooperate with the lifting mechanism on the tractor power platform to adjust the depth of the groove opened by the groove opening teeth 10.

[0034] The specific structure of the depth limiting wheel device 4 is as follows: Figure 1 and Figures 3 to 6 As shown, each set of depth limiting wheel devices 4 includes a sleeve 41 located outside the base frame 3 and fixedly connected to the first bearing seat 1, and the sleeve 41 and the first bearing seat 1 are fixedly connected by a mounting frame 46; a slide rod 42 is slidably connected in the sleeve 41, and a plurality of adjustment through holes 421 equidistantly distributed in the vertical direction are horizontally opened at the top of the slide rod 42, and the bottom end of the slide rod 42 is located outside the sleeve 41 and is installed with an inverted U-shaped plate 43, and the inverted U-shaped plate 43 is rotatably connected to the depth limiting wheel 44, and the axial line of the depth limiting wheel 44 is parallel to the axial line of the disc 9, that is, the walking direction of the depth limiting wheel 44 is parallel to the forward direction of the trencher; a horizontally distributed second bolt connection pair 45 is respectively arranged between one of the adjustment through holes 421 on each slide rod 42 and the sleeve 41, and specifically, the second bolt connection pair 45 includes a The second connecting bolt 451 and the second locking nut 452 are used. When the second locking nut 452 and the second connecting bolt 451 are removed in turn, the position of the slide bar 42 can be moved in the vertical direction along the sleeve 41, so that the height position of the depth limiting wheel 44 can be adjusted. After the height position of the depth limiting wheel 44 is adjusted to the right position, the screw end of the second connecting bolt 451 can be passed through the sleeve 41, and then passed through the slide bar 42 through the adjacent adjustment through hole 421 until the screw end of the second connecting bolt 451 is located outside the sleeve 41, and then the second locking nut 452 is sleeved on the second connecting bolt 451, and the heads of the second locking nut 452 and the second connecting bolt 451 are both abutted against the sleeve 41. In this way, after the height position of the depth limiting wheel 44 is adjusted, the height position of the depth limiting wheel 44 can be fixed.

[0035] Further, such as Figure 1 and Figures 3 to 5 As shown, a vertically distributed bulldozer plate 20 is installed on one side of each inverted U-shaped plate 43 close to the first bearing seat 1. Specifically, when in use, the bulldozer plate 20 can clean and trim the ground into a flat road, so that the depth limiting wheel 44 will not fluctuate during the forward movement, thereby ensuring the smooth operation of the depth limiting wheel 44.

[0036] Further, such as Figure 1 , Figure 3 and Figure 4 As shown, the sleeve 41 is a rectangular tube, and the slide bar 42 is a rectangular bar matched with the sleeve 41, so that when the height position of the depth limiting wheel 44 is adjusted, the slide bar 42 can be prevented from rotating, so that the axial line of the depth limiting wheel 44 can always be kept parallel to the axial line of the disc 9 to avoid the walking direction of the depth limiting wheel 44 from changing.

[0037] The specific manner in which the first rotating shaft 8 is connected to the output shaft of the gearbox 7 through the transmission device 5 is as follows: Figure 1 , Figure 3 and Figure 6 As shown, a vertically distributed second bearing seat 2 is installed on the base frame 3 located on one side of the gearbox 7, and a second rotating shaft 21 arranged parallel to the first rotating shaft 8 is rotatably connected to the inner side of the second bearing seat 2, and the second rotating shaft 21 is drivingly connected to the output shaft of the gearbox 7. Specifically, the second rotating shaft 21 is coaxially arranged with the output shaft of the gearbox 7, and the second rotating shaft 21 is connected to the output shaft of the gearbox 7 through a coupling; and the transmission device 5 includes a second sprocket 52 sleeved on the second rotating shaft 21 and a first sprocket 51 sleeved on the first rotating shaft 8, the first sprocket 51 and the second sprocket 52 are positioned opposite to each other, and a transmission chain is wound between the first sprocket 51 and the second sprocket 52, so that when in use, the first rotating shaft 8 can be driven by the gearbox 7 and the transmission device 5 to realize rotation; in addition, a casing 53 can be covered on the transmission chain, and the casing 53 can be fixed on the support rod 11, so that the transmission device 5 can be protected.

[0038] Further, such as Figure 1 , Figure 3 , Figure 5 and Figure 6 As shown, two inclined and relatively distributed reinforcing rods 22 are fixedly connected between one end of the base frame 3 close to the suspension frame 6 and the suspension frame 6. Specifically, the reinforcing rods 22 can increase the connection strength between the suspension frame 6 and the base frame 3 to ensure the structural stability of the base frame 3 and the suspension frame 6.
