Disclosure of Invention
The utility model aims to overcome the defects and shortcomings of the prior art and provides a disc harrow group of a combined soil preparation machine.
In order to achieve the above purpose, the utility model adopts the following technical scheme: a disc harrow group of a combined soil preparation machine is characterized in that: including the installing support, the installing support is L type structure, and its bottom sets up the axle sleeve, set up the center pin in the axle sleeve, run through on the center pin and set up the blade, cup joint bearing and driving gear on the center pin respectively, hang on the installing support and set up a pair of bearing frame, rotate between the bearing frame and set up the pivot, set up driven gear and driving sprocket respectively in the pivot, driven gear and driving gear meshing transmission are connected, driven sprocket is cup jointed to the outside of bearing, driven sprocket and driving sprocket pass through chain transmission and are connected, driven sprocket's side sets up rotatory cover, rotatory cover also overlaps on the center pin, and with center pin clearance fit, rotatory cover's outside sets up the knife rest, the top of knife rest sets up scrapes the mud sword, scrape the mud sword and support the side at the blade.
Further, the mud scraping knife is attached to the surface of the harrow piece.
Further, the top of bearing frame sets up on slide rail subassembly to fix through adjusting bolt.
After the structure is adopted, the utility model has the beneficial effects that:
according to the utility model, the clay on the harrow piece can be removed by arranging the mud scraping knife which rotates reversely with the harrow piece, so that the influence of the clay on the harrow piece is avoided, and the working efficiency of the scraper can be improved.
Drawings
Fig. 1 is a schematic structural view of the present utility model.
Reference numerals illustrate:
1 installing support, 2 axle sleeve, 3 center pin, 4 harrow piece, 5 bearing, 6 driving gear, 7 bearing frame, 8 pivot, 9 driven gear, 10 driving sprocket, 11 driven sprocket, 12 rotating sleeve, 13 knife rest, 14 mud scraper, 15 slide rail subassembly.
Detailed Description
The utility model is further described below with reference to the accompanying drawings.
In order to make the objects, technical solutions and advantages of the present utility model more apparent, the present utility model will be further described in detail below with reference to the accompanying drawings and detailed description. It should be understood that the detailed description is presented by way of example only and is not intended to limit the utility model.
Referring to fig. 1, a disc harrow group of combined soil preparation machine, including installing support 1, installing support 1 is L type structure, its bottom sets up axle sleeve 2, set up center pin 3 in the axle sleeve 2, run through on the center pin 3 and set up blade 4, cup joint bearing 5 and driving gear 6 respectively on the center pin 3, hang on installing support 1 and set up a pair of bearing frame 7, rotate between the bearing frame 7 and set up pivot 8, set up driven gear 9 and driving sprocket 10 respectively on the pivot 8, driven gear 9 and driving gear 6 meshing transmission are connected, driven sprocket 11 is cup jointed to the outside of bearing 8, driven sprocket 11 and driving sprocket 10 pass through chain transmission and are connected, driven sprocket 11's side sets up rotary sleeve 12, rotary sleeve 12 also overlaps on center pin 3, and with center pin 3 clearance fit, rotary sleeve 12's outside sets up knife rest 13, knife rest 13's top sets up the mud scraper 14, mud scraper 14 supports the side at blade 4. Specifically, when the soil preparation machine works, the harrow piece 4 rotates to cut the ground, the harrow piece 4 rotates to drive the central shaft 3 to rotate, so as to drive the driving gear 6 to rotate, the driving gear 6 drives the driven gear 9 to rotate, the driven gear 9 and the driving gear 6 rotate in opposite directions, meanwhile, the rotating shaft 8 drives the driving sprocket 10 to rotate, the driving sprocket 11 drives the driven sprocket 11 to rotate around the bearing 5 through the chain, the driven sprocket 11 drives the rotating sleeve 12 to rotate, the rotating sleeve 12 drives the knife rest 13 and the mud scraping knife 14 to rotate around the central shaft 3, and the rotation direction of the mud scraping knife 14 is opposite to that of the harrow piece 4, so that clay on the harrow piece can be removed, the influence of the clay on the harrow piece is avoided, and the working efficiency of the soil preparation machine can be improved.
In this embodiment, the mud scraping knife 14 is attached to the surface of the rake 4, so as to facilitate scraping the clay.
In this embodiment, the top of the bearing housing 7 is disposed on the slide rail assembly 15 and is fixed by an adjusting bolt. The bearing seat 7 can move left and right along the sliding rail assembly 15, namely, the distance between the mud scraping knife 14 and the harrow blade 4 can be adjusted, and the practicability is improved.
The foregoing is merely illustrative of the present utility model and not restrictive, and other modifications and equivalents thereof may occur to those skilled in the art without departing from the spirit and scope of the present utility model.
