Abstract

The utility model discloses a straw pulverizer, which comprises a suspension bracket and a supporting frame body connected at the rear part of the suspension bracket, wherein, the suspension bracket is connected with a dragging device; an immovable tool post and a roll shaft driven through a power source are orderly and horizontally arranged on the supporting frame body; a plurality of cutter shafts and pulverizing cutters installed at the end parts of the cutter shafts are radially and symmetrically arranged on the roll shaft; a plurality of groups of immovable cutters matching with the pulverizing cutters are arranged on the immovable cutter post; the length of cutter shafts which are arranged on the roll shaft and match with the tire position of the dragging device is more than that of cutter shafts at the other positions. When the straw pulverizer works, the pulverizing cutters installed on the cutter shafts with an ordinary length pulverize the straws on the ground plane, the pulverizing cutters installed at the end part of the lengthening cutter shafts pulverize the straws in the track, and thus, the straws on the ground plane and in the track can be well pulverized.

Description

Stalk crasher

Technical field

The utility model relates to farm machinery, especially relates to a kind of stalk crasher.

Background technology

Stalk crasher is the essential farm machinery in rural area, and the stalk that is retained in the field after the peasant utilizes it to gather in the crops is pulverized the direct returning to farmland as fertilizer sources.Cutter shaft length unanimity on the stalk crasher roll shaft of selling on the present market, during use, owing to be to make driven equipment with tractor or grain header, after tractor or grain header walking, the stalk at the rut place in pressure wheel past will be lower than ground level, so the stalk in the rut can not well be pulverized, and has influenced crushing effect.

The utility model content

The purpose of this utility model is to provide a kind of crushing effect better stalk crasher.

For achieving the above object, the utility model can be taked following technical proposals:

Stalk crasher described in the utility model, it comprises and joining hanger bracket of driven equipment and the supporting frame that is connected its rear portion, on the support frame as described above body, be horizontally disposed with tool fixing frame and the roll shaft by drive power source successively, radial symmetric is provided with many cutter shafts and the pulverizing cutter that is installed in described cutter shaft end on roll shaft, tool fixing frame is provided with the many groups stationary knife that cooperates with described pulverizing cutter cutting, is arranged on the length of being longer than other position cutter shafts with the length of the corresponding cutter shaft of tire location described driven equipment on the roll shaft.

The described cutter shaft that is arranged on the roll shaft sets in a row vertically.

Advantage of the present utility model is to be arranged on the length of being longer than other position cutter shafts with the length of the corresponding cutter shaft of tire location described driven equipment on the roll shaft; When stalk crasher is worked, the pulverizing cutter of installing on the normal length cutter shaft is the stalk on the plane all to pieces, the pulverizing cutter that install several groups of cutter shaft ends of extending is pulverized the stalk in the rut, so, can both well be pulverized with the interior stalk of rut on the ground.
