Ridging roller

Abstract

Ridging roller consists of: cross beams with a groove 2 and a lug 13, and side beams 1, which contain bearings 3 with washers 7 and a splined shaft 6 located inside a splined axle 4, on which a conical spring 9 with spherical discs 5 is mounted, and the cross beams with a groove 2 are connected by a wing nut 8 to the side beams 1, which have threads 12 for tie rods 10 with handles 11.

Description

The utility model belongs to agricultural machinery and can be used for forming ridges. The roller includes a frame, an axle and spherical discs with a located between them by a spring. The roller frame is made of composite material with the possibility of changing the distance between its side beams, which are interconnected by means of an adjustment mechanism. Diameter of turns of the spring decreases from the edges of the axis to its middle, and the outer turns of the spring are rigidly connected to convex sides of the spherical discs. When using a ridge roller, the quality of soil cultivation due to the formation of different ridge profiles depending on the technological requirements and the type of crop being processed. In addition, labor costs for roller maintenance are reduced. 2 ill. The utility model belongs to agricultural machinery, in particular it concerns rolling rollers. Known ridge-forming roller [Pat. SU No. 1517776. A01B29 / 04 - Publ. 10 / 30 / 89, Bull. No. 40.], which includes a frame, an axle and spherical discs loosely mounted on the axle. Between the spherical discs with The rings are arranged so that they can rotate freely on the axis and change the distance. Spherical discs installed with the convexity towards the axis of symmetry of the roller. The disadvantage of such a ridge roller is the difficulty of adjusting the distance between spherical disks. Unfortunately, during the patent search process, no close analogue of the utility model was found. The purpose of the utility model is to improve the quality of soil cultivation and reduce labor costs for maintenance of the ridge roller. The task is solved by the fact that the ridge-forming roller consists of: transverse beams with a groove 2 and an ear 13 and side beams 1, which contain bearings 3 with washers 7 and splined shaft 6, which is located inside the splined axis 4, on which the conical spring 9 with spherical disks 5, and transverse beams with groove 2 are connected by a ram nut 8 with side beams 1, which have threads 12 for tie rods 10 with handles 11. Fig. 1 shows a ridge-forming roller, a top view with local sections, and Fig. 2 - the same, side view with local sections. The ridge roller consists of: side beams 1, cross beams with grooves 2, bearings 3, splined axle 4, spherical discs 5, splined shaft 6, washer 7, ram nuts 8, conical spring 9, tie rods 10, handles 11, threads 12, earrings 13. The ridge-forming roller contains a frame consisting of side beams 1 and cross beams with grooves 2. On the side beams 1, bearings 3 with a splined shaft 6 with washers 7 are pressed in, which installed in a splined axle 4, on which spherical disks 5, which are installed with a convexity to axis, with the ability to move along the splined axis 4. The side beams 1 are fixed in the desired position relative to the cross beams with grooves 2 using lock nuts-rams 8. On the splined axis 4 between spherical disks 5 there is a conical spring 9, which is rigidly connected to the convex sides spherical disks 5. The spring is made with a decreasing diameter from the edges to the middle of the splined axis 4. The ridge roller works as follows: First, using the ram nuts 8, loosen the fastening of the side beams 1 and the cross beams beams with grooves 2 and, by rotating the handles 11 of the tie rods 10 along the threads 12 in the side beams 1, set the required width of the ridge profile, which is formed using spherical discs 5 and a conical spring 9 with coils of different diameters located between them. After that, the ram nuts 8 Next, the tractor driver connects the ridge roller by the serge 13 to the tractor and carries out workflow. When the ridge roller moves along rows of soil that has been previously loosened for laying seeds, a soil mound (crest) is formed, spherical disks 5, installed with the convex side inward for more uniform soil compaction, rolled together with the splined axle 4 in bearings 3, and due to pressure they form a ridge of soil, compacting it from the sides. Due to this A loose mulched layer of soil is formed, which reduces the evaporation of soil moisture. Improving the quality of soil cultivation is achieved by forming different ridge profiles soil depending on technological requirements and the type of crop being cultivated. In addition, thanks to the presence of the composition of the frame of the adjustment mechanism and the presence of a spring with coils of different diameters makes it possible reduce labor costs for maintenance of the ridge roller
