Abstract

The utility model relates to agriculture, namely, to a device for cutting rolls of high density. The technical result that can be obtained using the utility model is reduced to the creation of a simple design for cutting high-density rolls, which leads to increased productivity and lower energy consumption for grinding silage bales when using choppers-mixers-feed distributors, due to violation of the integrity of the surface densest and cohesive layers of high density roll. A device for cutting high-density rolls (see Fig. 1) consists of a knife 1, including a blade 2 attached to a knife blade 3 with screws 4. The knife 1 is pivotally mounted on the frame 5 and is fixed by a brace 6 at an angle α = 10-12 °, providing the cutting process with sliding and cutting the silage roll to a depth of 30 cm (see figure 1). Two guides 7 (see FIG. 3) are installed on the frame 5, which hold and guide the silage roll during cutting in the center of the frame 5 where the knife 1 is located (see FIG. 2). To give rigidity to the frame 5, the cross member 8 and the scarf 9 are welded (see figure 2). The longitudinal and transverse movement of the frame 5 when cutting the silage roll is limited by the side faces 10 of the stop 11, dug into the ground 12 to a depth of 50 cm. To fix the frame 5 in the stop 11, the rear wall of the frame 5 has a groove 13 profile and the size of which corresponds to the profile and size of the stop 11. The emphasis 11 has a square cross-section (see figure 2), which is fixed at the rear by a strap 14 and bolts 15 (see figure 1). To attach to the tractor (not shown in FIG.), When moving to another aft platform, transport earring 16 is attached to frame 5. When cutting high-density rolls, tractor 17 holds the tilter 18, the silage roll 19 above knife 1 (see FIG. .3)

A device for cutting rolls of haylage works as follows. Tractor 17 aggregated with a loader of rolls and tilter 18 accurately, captures the roll of silage 19 from the stack over the lateral cylindrical surfaces. Tractor 17 carries a roll of haylage 19, without removing the packaging film to the device installed on the aft platform. The knife 1 is fixed by a brace 6 which provides an angle α = 10-12 ° to the surface of the aft platform. With the front part of the lower generatrix of the cylindrical surface, the haylage roll 19 is lowered by the tilter 18 onto two guides 7 and the base of the knife 1. By translational movement of the tractor 17 with the tilter 18, the haylage roll 19 moves along the knife 1 parallel to the frame 5, which ensures the destruction of the integrity of the surface layer of the haylage roll 19 in the lower its parts. Tractor 17, driving over the device, cuts the roll of haylage 19 to a depth (25-30 cm).

Description

The technical field to which the utility model belongs.

The utility model relates to agriculture, namely, to a device for cutting rolls of high density.

The level of technology.

A device is known for cutting and loading silage, silage and similar materials, comprising a frame mounted on a tractor, a rotary boom with a knife and a bucket, and a hydraulic drive. The knife and bucket are mounted on the boom by means of a rotary frame, while the knife is equipped with a vibrator (see Pat. USSR No. 370919, Cl. A01D 87/00).

The disadvantage of this device is: the inability to use for cutting rolls of high density, bulky, high material consumption.

A device for cutting hay and hay rolls is known. It contains a frame with fingers attached to the bottom for gripping rolls. A knife (saw chain) with segments riveted to the roller chain is lowered by means of a hydraulic cylinder, which is connected by a hose to the tractor hydraulic system. The drive to the knife goes through a bevel gear, the driveshaft from the tractor PTO shaft (see. "Hay knife" // Rural machine operator 1991, No. 7 p.14).

The disadvantages of this device is that when cutting the roll, the knife (saw chain) becomes clogged with stalk material, the segments of the knife are pinched in the hay mass, the material is quite expensive in construction, the complexity of the structure, the use of manual labor when cutting and removing packaging and strapping material.

The closest in technical essence and the achieved positive effect and adopted by the authors for the prototype is a device for cutting rolls of hay and hay. It contains a frame, on the lower beam of which the teeth are horizontally located. A frontal knife is fixed on two side racks, the knife has eyes, in which double-acting hydraulic cylinders are articulated. For mounting on a loader or on the rear linkage of the tractor, the frame is equipped with brackets (see http // www.mammut.at / start.htm. Of the company "MAMMUT.).

The disadvantage of this device is the complexity and material consumption of the structure, the use of hydraulic equipment and the need for great effort when cutting the roll.

Disclosure of a utility model.

The objective of the utility model is: creating a simple design for cutting high density rolls, which leads to increased productivity and lower energy consumption of the process of grinding high density rolls when using choppers-mixers-feed distributors.

The technical result that can be obtained using the utility model is reduced to the creation of a simple design for cutting high density bales which leads to increased productivity and lower energy consumption for grinding silage bales when using choppers-mixers-feed distributors, due to violation of the integrity of the surface densest and cohesive layers of high density roll.

The technical result is achieved by the fact that the device for cutting high-density rolls containing a frame with a knife while two guides are fixed to the frame, and the knife is pivotally mounted in the center of the frame with a stop, which is installed with the possibility of adjusting the depth of cut of the high-density roll from 20 to 30 cm.

Utility Model Implementation

A device for cutting high-density rolls (see Fig. 1) consists of a knife 1, including a blade 2 attached to a knife blade 3 with screws 4. The knife 1 is pivotally mounted on the frame 5 and is fixed by a brace 6 at an angle α = 10-12 °, providing the cutting process with sliding and cutting the silage roll to a depth of 20-30 cm. (see figure 1). On the frame 5 there are two guides 7 (see Fig. 3) that hold and guide the haylage roll during cutting in the center of the frame 5 where the knife 1 is located (see Fig. 2). To give rigidity to the frame 5, the cross member 8 and the scarf 9 are welded (see figure 2). The longitudinal and transverse movement of the frame 5 when cutting the silage roll is limited by the side faces 10 of the stop 11, dug into the ground 12 to a depth of 50 cm. To fix the frame 5 in the stop 11, the rear wall of the frame 5 has a groove 13 profile and the size of which corresponds to the profile and size of the stop 11. The emphasis 11 has a square cross-section (see figure 2), which is fixed at the rear by a strap 14 and bolts 15 (see figure 1). To attach to the tractor (not shown in FIG.), When moving to another aft platform, transport earring 16 is attached to frame 5.

A device for cutting rolls of haylage works as follows.

To prepare the device for cutting haylage rolls to work, it is necessary: to transport the device to the place of work by attaching the transport earring 16 to the tractor 17, install the frame 5 parallel to the platform and secure

her, in emphasis 11, strap 14 (see figure 1). Check the sharpness of the blade 2 which is attached to the blade 3 with screws 4. If necessary, sharpen the blade 2.

Tractor 17 aggregated with a loader of rolls and tilter 18 accurately, captures the roll of silage 19 from the stack over the lateral cylindrical surfaces. Tractor 17 carries a roll of haylage 19, without removing the packaging film to the device installed on the aft platform. The knife 1 is fixed by a brace 6 which provides an angle α = 10-12 ° to the surface of the aft platform. With the front part of the lower generatrix of the cylindrical surface, the haylage roll 19 is lowered by the tilter 18 onto two guides 7 and the base of the knife 1. By translational movement of the tractor 17 with the tilter 18, the haylage roll 19 moves along the knife 1 parallel to the frame 5, which ensures the destruction of the integrity of the surface layer of the haylage roll 19 in the lower its parts. Tractor 17, driving over the device, cuts the roll of haylage 19 to a depth (25-30 cm). Before loading into the chopper-mixer-distributor of feeds, the tilter 18 lowers the roll of haylage 19 on the surface of the feeding platform and remove the packaging film and twine. Loaded into the grinder-mixer-distributor of feed by the tilter 18.
