Abstract

The utility model relates to a straw smashing device. The straw smashing device comprises a motor (1), a belt (2), a belt wheel (3), a straw box (4), a rotating shaft (5), a rotating wheel (6), four outer cutter holders (7) and four outer cutters (8), and is characterized in that inner cutter holders (9) are arranged on the rotating wheel (6), inner cutters (10) are arranged on the inner cutter holders (9), the inner cutter holders (9) are shorter than the outer cutter holders (7), the inner cutter holders (9) and the outer cutter holders (7) are arranged on the rotating wheel (6) in a staggered mode, and the inner cutters (10) and the outer cutters (8) are arranged on the rotating wheel (6) in a staggered mode. Because the double layers of cutters are used for cutting straw simultaneously, the straw can be thoroughly smashed, blockage is avoided, and working efficiency is improved.

Description

A kind of straw millstone

Technical field

The utility model belongs to agricultural machinery device technique field, specifically a kind of straw millstone.

Background technology

At present, mostly straw millstone is to be oppositely arranged two cutting knifes or four on runner cutting knife is used for cutting stalk, and the spacing of casing and cutting knife is larger, add the thickness of stalk, dry wet difference, constantly, crushing effect is bad, also often results in blockage in some stalk cutting.

Summary of the invention

The purpose of this utility model is for above weak point, provides a kind of and prevents that stalk cutting from constantly causing the straw millstone of obstruction.Realizing the technical scheme that the purpose of this utility model takes is: this straw millstone includes motor, belt, belt pulley, stalk case, rotating shaft, runner, circumscribed knife rest and outer cut, the number of circumscribed knife rest and outer cut is respectively four, it is characterized in that: described runner is provided with inscribe knife rest, on inscribe knife rest, inner cutter is set, described inscribe knife rest be shorter in length than circumscribed knife rest, the length of inscribe knife rest is that the half of circumscribed knife rest is advisable, inscribe knife rest and inner cutter and circumscribed knife rest and outer cut are crisscross arranged on runner, described inscribe knife rest and inner cutter and circumscribed knife rest and outer cut differ 45 degree and are crisscross arranged on runner.Rotate when electric machine rotation drives belt pulley, belt pulley, rotating shaft and runner are fixed on one, and therefore, runner rotates and drives outer cut and inner cutter to rotate simultaneously, and stalk is cut.

The utility model time cutting due to double-deck cutter, crushed stalk is totally thorough, has prevented obstruction, has improved operating efficiency.

Fig. 1 is structural representation of the present utility model;

Fig. 2 is the structural representation that arranges of the utility model intermediate slide and blade.

In figure, 1, motor, 2, belt, 3, belt pulley, 4, stalk case, 5, rotating shaft, 6, runner, 7, circumscribed knife rest, 8, outer cut, 9, inscribe knife rest, 10, inner cutter.

Embodiment

With reference to accompanying drawing, this straw millstone includes motor 1, belt 2, belt pulley 3, stalk case 4, rotating shaft 5, runner 6, circumscribed knife rest 7 and outer cut 8, the number of circumscribed knife rest 7 and outer cut 8 is respectively four, it is characterized in that: described runner 6 is provided with inscribe knife rest 9, inner cutter 10 is set on inscribe knife rest 9, described inscribe knife rest 9 be shorter in length than circumscribed knife rest 7, the length of inscribe knife rest 9 is that the half of circumscribed knife rest 7 is advisable, inscribe knife rest 9 and inner cutter 10 are crisscross arranged on runner 6 with circumscribed knife rest 7 and outer cut 8, described inscribe knife rest 9 and inner cutter 10 differ 45 degree with circumscribed knife rest 7 and outer cut 8 and are crisscross arranged on runner 6.Drive belt pulley 3 to rotate when motor 1 rotates, belt pulley 3, rotating shaft 5 and runner 6 are fixed on one, and therefore, runner 6 rotates and drives outer cut 8 and inner cutter 10 to rotate simultaneously, and stalk is cut.

Claims

1. a straw millstone, include motor (1), belt (2), belt pulley (3), stalk case (4), rotating shaft (5), runner (6), circumscribed knife rest (7) and outer cut (8), the number of circumscribed knife rest (7) and outer cut (8) is respectively four, it is characterized in that: described runner (6) is provided with inscribe knife rest (9), and inner cutter (10) is set on inscribe knife rest (9).

2. according to stalk reducing mechanism claimed in claim 1, it is characterized in that: described inscribe knife rest (9) be shorter in length than circumscribed knife rest (7), inscribe knife rest (9) and inner cutter (10) are crisscross arranged on runner (6) with circumscribed knife rest 7 and outer cut (8).

3. according to stalk reducing mechanism claimed in claim 2, it is characterized in that: the length of inscribe knife rest (9) is the half of circumscribed knife rest (7), described inscribe knife rest (9) and inner cutter (10) differ 45 degree with circumscribed knife rest (7) and outer cut (8) and are crisscross arranged on runner (6).
