DE3034404A1 - Crop pick=up and conveyor mechanism - has three rows of knives in conveyor channel one above another - Google Patents

Abstract

The pick-up and conveyor mechanism is intended for stem and leaf crops to be loaded onto a pick-up truck travelling alongside. The mechanism is mounted on the chassis of an agricultural machine and has a channel ending at the load platform. A pick-up drum on swing booms has tines rotating in the opposite direction to the conveyor tines, which work between them and also between knives protruding into the channel via slots. There are three rows of knives (7-9) in the channel (2), one above the other. The intervals between the knives can be so matched to those between the conveyor tines (3-5) that only two rows of knives are cutting at the same time.

Description

"Pick-up and conveying device for agricultural iwalm

and sheet material "The invention relates to a receiving and conveying device for agricultural stalks and leaves according to the preamble of the main claim, i.e. to a conveyor device known today under the term "loading wagon" agricultural work machines.

In these known machines, regardless of whether the Conveyor tines are designed as chain conveyors or are arranged on a conveyor drum are, in the conveying channel protruding cutting knives have become known. Especially with Chain conveyor it has become known to arrange two rows of cutting knives on top of each other, in order to create what is known as a silage cutting unit, which is used for an exact cut of about 5 cm cutting length.

It was previously of the opinion that the arrangement of even more Knives in the conveyor channel is not possible because on the one hand the space required for the Arrangement of the knives was too small, on the other hand, the then occurring load became too high, so that the advantages achieved by the additional knife the expense not justified.

The invention is based on the object of a conveyor for To improve loading wagons that several cutting knives on top of each other in the conveying channel are arranged and so close to each other that a very short cut material is achieved, which is particularly suitable as silage.

This object on which the invention is based is achieved by that three rows of knives are arranged one above the other in the conveying channel.

According to the invention it is then further proposed that 'the distance the cutting of each row of knives in coordination with those interacting with the knife edges Conveyor tines, of which, according to the invention, preferably six consecutive Rows are arranged, is chosen such that essentially only two rows of knives are effective at the same time cutting.

This inventive design of the receiving and conveying device it is achieved that a very small eschnittes good is achieved, because a close-standing Knife row acts on the conveyed goods, but the knives so against each other and are offset in setting on the conveyor tines that for the operation of the invention Knife assembly required power requirement is essentially not higher than when only two rows of knives can be arranged in the duct.

The invention is then also based on the object of the holder to improve the knife in the channel, so that the operability of the knife by the Farmer becomes easier and safer.

This object on which the invention is based is achieved by that the two lowest rows of knives are arranged on a central support, the is carried by one or more carrier carriers. The swivel bracket is included pendulum but fixable suspended around a pivot point that is approximately in the vertical The center of gravity lies. If it is necessary to replace the knives, they can be swiveled out together with the central support and the swivel support and are then freely accessible without the need for this pivoting out and subsequent pivoting again a high power requirement would be required.

Each knife in the two lower rows can be pivoted about a pivot point stored and held in its working position by resilient buckling struts, so that a so-called stone protection is created, i.e. the knives can opposite avoid hard parts.

Finally, it is proposed according to the invention that between each Conveyor prongs a cover rod of the Förderkanalwanduna is arranged, so that a good Abutment for that to be cut Well done, being there but it is also possible to leave out the second cover rod in order to achieve the ~ to reduce the weight of the entire facility.

An exemplary embodiment of the invention is described below with reference to FIG Drawings explained.

The drawings show a conveying channel relatively schematically in FIG. 1 with chain conveyor and six controlled tine rakes as well as with three rows in the Cutting knife engaging the conveying channel, in FIG. 2 the arrangement according to FIG. 1 at pivoted central support and an illustration in FIG. 3 in a schematic representation the sequence of the various cutting operations.

In the figures, 1 denotes a take-up drum that is used in the illustrated embodiment is arranged leading, the Rotate the conveyor tines of this receiving drum in the direction of arrow F, the material to be conveyed pick up from the ground and convey into the conveyor channel 2. Reach into the conveyor channel A conveyor tines, of which the conveyor tines 3, 4 and 5 can be seen.

The conveyor chain carries a total of six such conveyor tines. There the end The conveyed material delivered to the conveying channel arrives in a not shown in detail Load space of a loading wagon and there on the so-called scraper floor 6, which is intermittent conveys the load to the rear.

In addition to the conveyor tines 3 to 5, 2 rows of cutting knives engage in the loading channel 7, 8 and 9, these cutting knives, viewed from above, with a gap between them stand, as is illustrated in FIG. 3. Here are the rows of knives denoted by the same reference numerals as in FIGS.

The knives are held differently, namely the top one Knife carried by a support device 10, while the two lower knives be borne indirectly by a central support ii, which in turn is supported by a swivel support 12 is carried, which can be pivoted about the pivot point 14, but can be locked in the position shown in Fig. 1, so that then the rows of knives 8 and 9 engage in the conveying channel 2.

Each knife of the two lower rows of knives 8 and 9 can be pivoted mounted about a pivot point 15 or 16 and is shown in FIG inclined working position held by buckling struts 17 and 18, the buckling struts 17 and 18 can also be designed twice and consist of spring steel, so that they can evade with a corresponding pressure on the cutting edge of the knife and thereby represent the backup.

The knives are set using the eccentric control 19, with a mer or less inclined by rotating the eccentric accordingly Engagement of the knife in the channel is achievable.

From the illustration in Fig. 3 it can be seen that the actual Cover rods 20 can be U-shaped so that it is possible that the tips of the knives even partially engage in the interior of this U-profile, whereby a particularly good cutting effect can be achieved.

Furthermore, it can be seen from Fig. 3 that the cutting portions always are supported by two conveyor tines, so that also through this arrangement one good cutting process can be achieved.

The illustration in Fig. 1 clearly shows that essentially only two rows of cutting knives are effectively engaged, namely according to the illustration Fig. 1 the cutting knife rows 8 and 9, while the cutting knife 7 its work has completed, so that the effort is relatively low, although a high cutting performance is achieved.
