RU2367137C1 - Device for cuttong rolls of stalk fodder - Google Patents

Abstract

FIELD: agriculture.

SUBSTANCE: device for cutting rolls of stalk fodder is meant for preparing fodder rolls for feeding animals, mainly for use in pens on animal farms. The device has chain conveyors fitted head-on, on the chains of which flange catch-locks are cantilever fitted on hinges. Below the conveyors there is a cone-shaped roller-breaking unit. The roller is moved to the upper zone of the device using an inclined conveyor, and is thrown down. Upon colliding with the said cone-shaped unit, the roller breaks and the feed takes a crumbled form. Animals prefer crumbled feed to rolled-up feed. If the roll does not break up, it is held on the breaking unit and vertical conveyors are switched on. The flange catch-locks raise the said roll and, on the section where the flange catch-locks stop interacting with feeler units, racks take a position closer to the vertical. The roll falls down and the cycle is repeated.

EFFECT: proposed device provides for complete break up of rollers and obtaining crumbled feed from rolls of different density and moisture.

Description

The alleged invention relates to agriculture and can be used to cut coils of coarse stalked feed on livestock farms, mainly on walking grounds.

A device is known for cutting rolls of stalk feed, comprising a carriage mounted on a frame with the possibility of reciprocating movement in a vertical plane, a mechanism for driving a carriage, a device for gripping and orienting a roll, a device for fixing a roll, a drive for a cutting tool (see av. USSR No. 1588320, class A01F 29/00). The disadvantages of this device include the complexity of the design, the need to ensure the interaction of mechanisms, the need for periodic updates of the cutting elements of the knife device.

The closest in structural design and technical essence is the installation for cutting rolls, containing chain conveyors vertically mounted towards each other with a gap between them and a link destroying the roll installed below the conveyors in the middle of the gap (see av. St. USSR No. 1762795, class A01F 29/00 for 1987).

The disadvantages of this device include the impossibility of ensuring a sufficiently complete destruction of the feed roll and bringing it to the state most favorable for feeding to animals, as well as the need for periodic sharpening and replacement of cutting elements.

The objective of the proposed installation is to bring the feed roll to its complete destruction and providing the animals with the most comfortable eating process. This is achieved by the fact that in the installation for cutting stalked feed rolls containing chain conveyors vertically mounted towards each other with a gap between them and a breaker link installed below the conveyors in the middle of the gap, copiers not reaching their upper sprockets are fixed inside the chain conveyors, and shelf links are cantileverly mounted on chain links with the possibility of rotation in the vertical plane, while on each of them a lever is tilted fixed, I interact with a copier to ensure horizontal fixation of the shelf grip on the ascending branch of the chain conveyors, and the destructive roll link is made in the form of fan-shaped and vertically fixed triangular plates, while the contour of the shelf captures is made to ensure that the gaps between the plates intersect when the ascending branches of the chain conveyors move, while the destructive roll link is raised above the level of the lower sprockets, the chain conveyors are mounted to ensure their synchronous th operating mode.

According to the patent and scientific and technical literature, the claimed combination of essential features is unknown, which allows us to judge the compliance of the proposed technical solution with the level of the invention.

The technical result consists in the fact that in the proposed installation, the coarse feed roll is dropped from a height onto the destructive link (divider), while the kinetic energy accumulated during the free fall of the coil, when the coil meets the destructive link (divider) is spent on its destruction .

In the proposed installation, it is possible to repeatedly raise the roll and drop it onto the destructive link (divider), which allows using the proposed device to ensure its complete destruction. Animals are more likely to eat stalked feed in loose form, while feed losses are reduced and more complete eating is provided.

Figure 1 presents a General view of the installation, figure 2 is a section aa in figure 1, figure 3 is a remote element 1 in figure 2, figure 4 is a section bb in figure 1, figure 5 is a section bB in figure 4.

The plant for cutting stalk feed rolls contains a frame 1 (not fully shown in the drawing), vertically mounted chain conveyors mounted vertically towards one another, each of them consists of upper sprockets 2, lower sprockets 3, chains 4, on connecting elements 5 links 4, bearings 6 are fixed, on which a shelf grip including a shelf 7 is mounted cantileverly, support axles 8 are attached to the shelf along its edges, the ends of which are nested in bearing bearings 6. A lever is tilted to the shelf 7 r 9, on which the end of the roller 10 is mounted.

Copiers 11 are vertically fixed inside the contours of the chain conveyors, while the upper edge of the copier does not reach the upper sprockets 2 of the chain conveyors, and the lower end of the copier is made with a bend for a smooth entry of the roller 10 onto the copier 11 during the operation of the conveyors.

Below the chain conveyors, a roll-breaking link is fixed, made in the form of a fan-shaped and vertically arranged triangular-shaped plates 12 radially attached to a pointed rod 13, the sharp end of which is directed upward. The outer edges of the plates 12 may be pointed. The profile of the shelf 7 shelf captures made with the intersection of the gaps between the plates 12. The installation has a guard 14, a guide receiver 15, the conveyor 16, equipped with rake for feeding the roll.

Installation for cutting rolls is as follows. The roll is conveyed by the conveyor 16 to the guide receiver 15 and is dropped down along the fence 14. In free fall, the roll gains kinetic energy and is destroyed when it encounters the pointed rod 13 and the plates 12.

The destroyed roll falls to the site. In case of incomplete destruction of the roll, vertical chain conveyors are turned on, while the shelf grips of the two conveyors, when each of them interacts with the lever 9 and the roller 10 with the copier 11, occupy a horizontal position and, when moving upward, intersect the gaps between the plates 12, remove the undamaged roll from the plates. When moving along the ascending branch of the conveyor chains to the upper edge of the copiers 11, the interaction of the lever 9 with the roller 10 ceases, while the shelf clamps mounted in the cantilever bearings 6 are tipped over and occupy a close vertical position, and the roll falls out and gains kinetic energy which, when meeting (impact) with a link destroying the roll, is spent on the destruction of the roll. Cycles can be repeated until the roll is completely destroyed. Chain conveyors operate synchronously.

The proposed installation, equipped with shelf grippers, ensures the complete destruction of rolls with various density characteristics, various humidity during use, leaves stalked feed composition remains and remains on the walking platform, more complete animal feed is provided.

In the proposed installation, the loading height of the roll can be reduced and brought to the possibility of use for loading forklifts.
