A road paver (F) has a paving screed E the working width of which can be adjusted continuously. In order to further enlarge the working width in steps at least one paving screed extension can be mounted. A distributing auger (6) is supported in a distributing auger support (4). Distributing auger extensions (19a, 19b, 19c) can be mounted to the distributing auger (6). Scraper blades (20) are arranged in casting travelling direction behind distributing auger (6). At least a scraper blade section (20a) functionally associated to a mounted paving screed extension (13) is carried by a channel sheet steel plate (15) being part of the mounted distributing auger extension (19a, 19b, 19c). The scraper blade section (20a) can be adjusted in height direction together with the distributing auger support (4) via a drive (7) which can be remotely controlled during a casting process.

A harvester has a harvesting device arranged in a traveling and working direction of the harvester in front of a driver's cab. The harvesting device has first, second, and third parts and extends with its length in a direction transverse to the traveling and working direction. At least the first and second parts are swivel parts that are pivotable about approximately 180 degrees about a pivot axis, respectively. The pivot axis extends approximately in the traveling and working direction, such that the swivel parts are transferable from a working position in which the swivel parts extend transversely to the traveling and working direction into a transport position. In the transport position legally permissible dimensions for traveling on roads are observed. A longitudinal extension of the swivel parts transverse to the traveling and working direction matches at least approximately a maximum legally permissible transport width.

A compacting device (40) for attachment to an earthmoving machine (2) to compact a substrate is described. The compacting device (40) includes a plurality of wheel assemblies (41, 42, 43) mounted for rotation in bearings (46). A support is also provided, having a base part (48) that is adapted to be mounted to the earthmoving machine (2). One or more bearing support members (47) extend from the base part (48) and between the wheel assemblies (41, 42, 43) to support the bearings (46). Each wheel assembly (41, 42, 43) includes a set of ground-contacting feet (44) secured to and peripherally spaced apart around a rim portion of the wheel assembly (41, 42, 43). In this arrangement, when the device (40) is rolled over the substrate a first foot of said set of ground engaging feet (44) contacts the substrate between axial width limits that differ from axial width limits of a second foot of said set of ground engaging feet (44).

The invention relates to a teeth-like self-cleaning top comb for a cotton comber. Tooth sheets (2) are connected between a straight panel and a bent plate (3); the cross section of the tooth sheets (2) is of a wedge shape, wherein an alpha angle is 11 to 13 degrees; a beta angle is 17 to 19 degrees; and a gamma angle is 9 to 11 degrees; C and E are connected through an arc, the value of R is 2.3 to 3 mm, and edges of the C and the E are clearance angles and have no burr; the values of the C and D are 0.200 to 0.05 mm, the BC value of a working height of a tooth sheets section is 5.5+ / -0.015 mm, the value of AB is 3 mm, the value of BE is 0.6 to 0.8 mm, and the value of BF is 2.06 mm; and the alpha value of the lower end of the tooth sheets section thickness is 0.06 to 0.08 mm, and the beta value of the upper end of the tooth sheets section thickness is 0.20 to 0.25 mm. The top comb has the good carding effect, and self-cleans carded neps, flocks and impurities in the process of carding, so that the use performance of the top comb is improved and the working efficiency is improved.

The invention relates to integrated cleaning equipment for a water conservancy diversion canal. The integrated cleaning equipment comprises a trolley and a water tank, and a spraying device is mounted on the trolley; two sets of electric push rods extending downwards in an inclined mode are fixed to the water tank, a frame is jointly installed at the lower ends of the two sets of electric push rods, a first cleaning roller is rotationally installed on the lower end face of the frame, and a first motor rotating coaxially with the first cleaning roller is installed at one end of the first cleaning roller. Connecting rods are installed on the edges of the two sides of the frame body, bases are hinged to the upper end faces of all the sets of connecting rods, second motors are installed on the bases, and second cleaning rollers are coaxially arranged on output shafts of all the sets of second motors in a rotating mode. First telescopic rods are hinged to the two sets of vertical rods, limiting rings are hinged to the first telescopic rods, and the second cleaning rollers are inserted into open holes in the limiting rings to rotate. A battery is mounted on the trolley. According to the cleaning equipment, impurities on the inner walls of the two sides of the diversion canal are cleaned, and the defect that existing cleaning equipment can only clean the inner bottom face of the diversion canal is overcome.
