Description

TECHNICAL FIELD

[0001] The utility model belongs to water conservancy engineering machinery technical field, concretely relates to a water conservancy channel ditcher. BACKGROUND

[0002] The water conservancy channel ditcher (continuous wall ditcher) is a mechanical equipment used in the fields of farmland water conservancy engineering, drainage system construction, etc., mainly used for excavating ditches to guide water flow, and prolonging the excavation of the ditch through moving continuous ditching operation. In order to meet the ditching requirements of different depths, the ditcher with a shorter cantilever cannot meet the requirements of ditching depth through the adjustment of the lowering angle, and the traditional ditcher usually responds by lengthening the cantilever. However, lengthening the cantilever also increases the overall size of the equipment, leading to inconvenience in transportation and movement, especially when working in narrow or complex terrain, the flexibility is poor.

When the ditching width needs to be changed, different width chain belt scrapers must be replaced. Such operation not only consumes time and effort, but also requires additional provision of multiple specifications of scrapers, increasing the use cost and maintenance difficulty of the equipment.

[0027] The side surface of main cantilever 1 is provided with power mechanism 14 for driving two groups of chain scrapers 6 to rotate, the fixed frame 10 is rotatably installed on main cantilever 1, the traction plate 13 is arranged on the fixed frame 10 for connecting with the traction equipment, the fixed frame 10 is also arranged on the traction equipment, the hanging support plate 12 is rotatably installed on main cantilever 1, two groups of chain scrapers 6 are installed in the hanging support plate 12, a plurality of lifting hydraulic cylinders 11 are arranged above main cantilever 1, the fixed end of lifting hydraulic cylinder 11 is rotatably arranged on the upper side of fixed frame 10, the extension end of lifting hydraulic cylinder 11 is rotatably arranged on the hanging support plate 12, the control end of telescopic hydraulic cylinder 4 and lifting hydraulic cylinder 11 is arranged on the traction equipment;

[0028] The upper part of the sleeve hole cantilever 2 is provided with two groups of vertical push-up roller sets 8a, which are in transmission connection with the bottom surface of the chain belt scraper 6. The sleeve hole cantilever 2 is provided with a rotating support plate 7, and the two groups of push-up roller sets 8a are arranged on the upper side of the rotating support plate 7. The telescopic cantilever 3 is provided with a linkage plate 8, which is arranged inside the chain belt scraper 6 and is in transmission connection with the rotating support plate 7.

[0029] As an optional embodiment, the adjusting transmission mechanism 5 comprises a transmission fixed seat 51 arranged on the side surface of the telescopic cantilever 3 or the upper surface of the main cantilever 1. The two side plates of the transmission fixed seat 51 are respectively provided with slide rail shafts 52 on the opposite sides. The two side plates of the transmission fixed seat 51 are provided with transmission wheels 53 connected with the slide rail shafts 52. One of the slide rail shafts 52 is provided with a reciprocating screw 54 rotatingly penetrating in it. The reciprocating screw 54 is arranged on the side of the other slide rail shaft 52. The side of the transmission fixed seat 51 is provided with a brake plate 55 fixedly connected with one side of the reciprocating screw 54. The brake plate 55 is provided with a fastening screw 55a threadedly connected with the side of the transmission fixed plate. The reciprocating screw 54 is provided with two groups of opposite helical threads. In this way, the two groups of transmission wheels 53 can be driven to move close to or away from each other by the two groups of opposite helical threads on the reciprocating screw 54, so as to adjust the width of the two groups of chain belt scrapers 6.

[0030] Referring to the accompanying drawings Figure 3 and the accompanying drawings Figure 4 The number of transmission wheels 53 is two and symmetrically arranged. The transmission wheel 53 comprises a transmission gear disc 53a and a slide hole sleeve 53b rotatingly arranged on the transmission gear disc 53a. The transmission gear disc 53a is in meshing connection with the chain belt on the chain belt scraper 6. The slide hole sleeve 53b is slidingly arranged on the slide rail shaft 52 through the shaped sleeve hole. The side of the slide hole sleeve 53b is provided with an extension ring 53c sleeved on the reciprocating screw 54. The reciprocating screw 54 is provided with a screw hole disc 53d threadedly matched thereon. The screw hole disc 53d is arranged in the extension ring 53c. The shapes of the slide rail shaft 52 and the slide hole are hexagonal. In this way, the rotation of the transmission wheel 53 can be limited, so as to avoid the transmission wheel 53 being driven to rotate when the chain belt scraper 6 rotates, thereby preventing the displacement of the transmission wheel 53 from affecting the width adjustment of the two groups of chain belt scrapers 6.

[0031] Furthermore, the power mechanism 14 includes a rear fixed seat 14a disposed on the side of the main cantilever 1. A transmission shaft 14b is rotatably disposed on both side plates of the rear fixed seat 14a. Two smooth sleeves 14c are slidably sleeved on the transmission shaft 14b. The transmission shaft 14b is configured in a hexagonal shape, which not only drives the smooth sleeves 14c to rotate, but also allows the smooth sleeves 14c to slide on the transmission shaft 14b to adapt to the adjustment requirements of the transmission mechanism 5. Two drive gear disks 14d are disposed on the two smooth sleeves 14c, which are respectively engaged with the chain belts on the two sets of chain scrapers 6. The end of the transmission shaft 14b is connected to the traction equipment or the power equipment. With this configuration, the power mechanism 14 can drive the two drive gear disks 14d to rotate through the transmission shaft 14b, thereby driving the two sets of chain scrapers 6 to engage and rotate.

[0032] With the above structure, during telescopic adjustment, the telescopic hydraulic cylinder 4 can be extended by the control button on the traction equipment, which drives the telescopic cantilever 3 to extend into the sleeve cantilever 2. At the same time, the linkage plate 8 pulls the rotating support plate 7 to rotate, so that the rotating support plate 7 drives the push roller group 8a to rotate, thereby providing rolling support for the chain scraper 6. In this way, the cantilever telescopic adjustment of the trenching depth can be realized.

[0033] By loosening the fastening screw 55a on the adjusting transmission mechanism 5, the brake plate 55 is rotated to drive the reciprocating screw 54 to rotate, causing the reciprocating screw 54 to drive the two screw hole discs 53d to move away from or towards each other, thereby synchronously driving the two transmission gear discs 53a to move, thereby adjusting the translational excavation width of the two sets of chain scrapers 6. After adjustment, the fastening screw 55a is threaded to the transmission fixing seat 51 to fix the position of the transmission gear discs 53a, thereby maintaining the excavation width. This design improves the functional versatility of the trencher and facilitates trenching operations in water conservancy channels.
