CS253718B2 - Crushing and raking-up device for maize straw and other residues after machine cob breaking - Google Patents

Description

BACKGROUND OF THE INVENTION The present invention relates to a device for crushing and raking corn maize and other residues after machine breaking into staggered rows.

The crushing, shredding or ripping of the remaining corn straw on the ground is a current agricultural task, especially in the cultivation of maize for industrial purposes.

In recent years, the importance of raking up the corn straw residues has become increasingly important, since by further processing, for example into bales or briquettes, valuable heating material can be obtained or the corn straw residues can be used as animal feed.

For crushing corn straw and other residues from corn straw, mainly rotary straw choppers with a vertical shaft are used.

To a lesser extent, rotary straw cutters with horizontal shafts are also used. However, the problem of crushing and concomitant aggregation of crushed straw residues into tapered rows is still not solved in either type of cutter.

The disadvantage of both types of equipment is that they spread the crushed material on the ground. Windrowing suitable for harvesting by a machine must be carried out by other equipment, such as a tedder or rake.

Therefore, there is a need to develop a device that simultaneously crushes and removes straw remnants into tapered rows.

This object is achieved by a device according to the invention which makes it possible to cut, crush and rake straw residues into rows in a single operation.

It is an object of the present invention to provide oblique baffle plates of material at an angle of about 30 [deg.] To the horizontal of the back cover.

The advantage of the invention is that it simultaneously crushes and summarizes corn straw and other residues after the machine breaks into narrowed rows.

An exemplary embodiment of the device according to the invention is described in detail with reference to the drawings, in which Fig. 1 is a side view and Fig. 2 is a top view of the device according to the invention shown in Fig. 1.

In the two side plates 6 of the semi-mounted frame 4 resting on the supporting wheels 2, generally pneumatic, a hollow rotating shaft 6 is provided, provided with swinging bent knives 6. The front domed cover plate surrounding the rotatable part of the apparatus comprising a hollow rotating shaft 4 with swinging blades 4 is mounted at a distance of 40 mm from the outer end of the swinging blades 4. The rear cover plate odch_ deviates from the horizontal by an angle of beta = 15 °.

The rotatable part of the device according to the invention is driven by an articulated shaft 6, an angular drive mechanism 6 and a chain 60. The support wheels 4 are raised and lowered by the hydraulic working cylinders 11.

In front of the hollow rotating shaft 6 are inclined plates 14 forming an angle of 30 ° with the horizontal to direct the material into the tapered rows. The rotatable part of the device according to the invention is driven laterally by the chain 10 via a countershaft 12, a torque coupling 43, an angular gear mechanism 8 with bevel gears and an articulated shaft 6.

A freewheel is mounted in the PTO shaft to prevent the reverse clutch 13 from engaging the angular gear and the chain overload of said drive elements.

running. The purpose of the device 10 is to provide protection against the inclined plate 14 in the event of a non-rows of the device. In operation, the device according to the invention is mounted on the support wheels 2, or on supports which are articulated to the semi-mounted frame A and fixed horizontally to the frame 1 when traveling.

Further hydraulic cylinders (not shown) may be placed behind the support wheels 2 for lifting the device in bends or lowering it to the transport position.

Drawn by a tractor. The rotatable part is driven by an outwardly arranged hydraulic. working

The described embodiment of the device according to the invention is the universal joint shaft of the tractor over the PTO shaft. The height adjusting rollers 11 can be driven by connecting a high pressure oil line arranged on the device according to the invention to the tractor hydraulic system.
