DISC HILLER

Abstract

This utility model relates to agricultural engineering, specifically to tillage implements, and can be used for ridge-cutting and soil loosening, while eliminating weeds between rows when growing row crops on raised beds. The technical result of this utility model is an increase in the depth and quality of ridge loosening. This is achieved by welding a shelf to the frame symmetrically along the longitudinal axis of the hiller, in front of the disks. A bracket with a hole for attaching a stand is attached to this shelf with clamps. The stand, with a winged paw at the end, is inserted into the bracket's hole and can be adjusted in height and secured with a bolt.A disc hiller consisting of a frame, a coupling device, posts fixed relative to the frame at a certain pitch, providing a row spacing of 45, 60 and 70 cm using cotter pins through openings made in the frame and frame posts, curved disc posts made of round pipes with a slot and two holes for bolts, sectors attached to the slot movably with the possibility of fixation, hubs with discs attached to the sectors, wherein a shelf is welded to the frame symmetrically along the longitudinal axis of symmetry of the hiller in front of the discs, to which a bracket with an opening for attaching a post is attached with clamps, a post with an arrow-shaped paw at the end is inserted into the opening of the bracket with the possibility of moving in height and fixing with a bolt.

Description

[0001] The utility model relates to agricultural engineering, in particular to tillage implements, and can be used for cutting ridges and loosening the soil with the destruction of weeds in the inter-row spaces when growing row crops on ridges.

[0002] A disc hiller is known [RU Copyright Certificate Patent No. 2759865, IPC class A01B 13 / 02, 2021], which consists of a frame, a coupling device, frame posts, disc posts, while the frame, frame posts, disc posts are made of round pipes, the disc posts are made of a curved shape with a slot and two holes for bolts, while a sector is movably attached to the slot with the possibility of fixation, a hub is rigidly attached to the sector, to which a disc is attached with the possibility of rotation, while the frame posts are provided with threaded holes for the disc post fixing bolts and the frame post fixing bolts, while the design provides the possibility of a floating position in a horizontal plane with the possibility of unscrewing / screwing in the limiting bolts and then fixing them with lock nuts.

[0003] The disadvantage of the well-known disc hiller is the difficulty of setting the specified processing width and the impossibility of quickly adjusting the row spacing in steps.

[0004] The closest analogue to the claimed technical solution, adopted as a prototype, is a disc hiller [RU Author's Certificate Patent No. 231306, IPC class A01B 21 / 04, 2025], consisting of a frame, a coupling device, posts fixed relative to the frame at a certain pitch, providing a row spacing of 45, 60 and 70 cm using cotter pins through holes made in the frame and frame posts, curved disc posts made of round pipes with a slot and two holes for bolts, sectors movably attached to the slot with the possibility of fixation, hubs with discs attached to the sectors.

[0005] The disadvantage of the prototype is the insufficient depth and quality of loosening the ridges.

[0006] The technical result of the utility model is to increase the depth and quality of ridge loosening.

[0007] The technical result is achieved due to the fact that a shelf is welded to the frame symmetrically along the longitudinal axis of symmetry of the hiller in front of the disks, to which a bracket with a hole for attaching a stand is attached with clamps, the stand with an arrow-shaped paw at the end is inserted into the hole of the bracket with the ability to move in height and fix with a bolt.

[0008] The specified set of essential features ensures the appearance of new properties in the claimed disc hiller, different from the prototype.

[0009] Fig. 1 shows a diagram of a disc hiller, a top view, Fig. 2 shows the same, a side view when interacting with the soil.

[0010] Disc hiller, consisting of a frame 1, fig. 1, coupling device 2, posts 3 fixed relative to the frame with a certain step, providing a row spacing of 45, 60 and 70 cm with the help of cotter pins 4 through openings made in the frame and posts of frame 3, curved posts of disks 5 made of round pipes with a slot and two openings for bolts 6, sectors 7 attached to the slot 8 movably with the possibility of fixation, hubs 9 with disks 10 attached to sectors 7, wherein a shelf 11 is welded to the frame symmetrically along the longitudinal axis of symmetry of the hiller in front of the disks 10, to which a bracket 12 with an opening for attaching a post is attached with clamps 13, a post 15 with an arrow-shaped paw 16 at the end is inserted into the opening of the bracket 12 with the possibility of moving in height and fixing with a bolt 14.

[0011] The disc hiller works as follows.

[0012] Before work, a bracket 12 is attached to the shelf 11 welded to the frame 1 with brackets 13. A post 15 with a lancet paw 16 is inserted into the hole of the bracket 12 and fixed with a bolt 14 in such a position that the blade of the lancet paw 16 is located below the lower point of the disks 10 by a distance of c, Fig. 2.

[0013] In the ridge-cutting mode, the 16 wing-shaped plow loosens the soil along the ridge width to a depth of a, which is determined by the root development depth of the specific crops to be planted. Following the 16 wing-shaped plow, the 10 discs form a soil ridge of height b. The passage of the disc working element results in a well-loosened ridge with a deepened depth of c and a loosened base.

[0014] In the hilling option, the stand with the arrow-shaped paw is removed by unscrewing the brackets 13, and only the discs 10 perform the work, restoring the slopes of the ridges and destroying weeds.

[0015] Thus, the stated technical result is achieved.
