Abstract

The utility model relates to a bract smashing device of a maize harvesting machine. The bract smashing device of the maize harvesting machine structurally comprises a machine shell, a stationery cutter set, a cutter shaft, a group of moving cutter disks and moving cutters, wherein the stationary cutter set is fixed in the machine shell and composed of a row of paratactic stationary cutters, the cutter shaft is horizontally installed in the machine shell, the group of moving cutter disks are installed on the cutter shaft, and the moving cutters are fixed on the moving cutter disks. The bract smashing device is installed on the maize harvesting machine, maize bracts which are discharged out of a lower port of a stripping machine enter into the smashing device through an upper port of a shell body of the smashing device, are smashed into pieces under the coordination effect of the moving cutters and the stationary cutters of the smashing device, and then fall on field through a lower port of the shell body. Due to the fact that the maize bracts are smashed and discharged through the bract smashing device, a seeder is effectively prevented from being blocked and emergence of seeds are prevented from being negatively influenced when following-up seeding is carried out. Moreover, the smashing of the maize bracts is more favorable for decomposition, the effect that biomass returns to the field is strengthened, and crops grow up beneficially.

Description

Maize harvesting machine bract reducing mechanism

Technical field

The utility model relates to a kind of reducing mechanism, specifically a kind of maize harvesting machine bract reducing mechanism.

Background technology

Existing maize harvesting machine is when work ,The corn of harvesting enters ear-picking unit and carries out the separation of stalk fringe, and isolated corncob is sent to the debarker device and carries out skinning operations, and the corncob of having shelled skin is transported to storing bin, peels the bract that comes and is directly discharged and mix in the soil in farmland when ploughing.Because the profile of bract is larger, and can not be decomposed, therefore immediately; in follow-up sowing work, the bract in the soil usually can be caught on by sower, along with advancing of sower; collude with bract can block the sowing opening of sower, thereby affect the broadcast of seed.In addition, the bract that is mixed in the soil also can often can cover the seed that some are sowed, thereby impact is emerged and seedling grows normally.

The utility model content

The purpose of this utility model just provides a kind of maize harvesting machine bract reducing mechanism, bract is carried out pulverization process when the reaping corn, avoids bract integral body to enter behind the field follow-up sowing and growth of seedling adverse effect.

The utility model is achieved in that a kind of maize harvesting machine bract reducing mechanism, include: casing, be fixed on the stationary knife group that is formed by row stationary knife arranged side by side in the described casing, be installed in the horizontal cutter shaft in the described casing, be installed in one group of movable knife disc on the described cutter shaft, and be fixed on the moving knife on the described movable knife disc.

Two sides at each described movable knife disc all is equipped with moving knife, and the blade part of described stationary knife extend between the fixing described moving knife in described movable knife disc two sides in the formed crack.

The knife face of described moving knife is triangle, is evenly equipped with three described moving knife in every one side of described movable knife disc.

The utility model is mounted in the debarker lower position of maize harvesting machine, the made from bracteal leaf of corn of discharging from the debarker end opening is by the housing of this cracker inside that directly enters cracker suitable for reading, and under the mating reaction of the moving knife of cracker and stationary knife, drop on the field by the housing end opening after being ground into fragment.Made from bracteal leaf of corn pulverize to be discharged by this device, when effectively having prevented follow-up sowing to the obstruction of sower and the adverse effect that seed is emerged, and, be easier to decomposition after the bract pulverizing, increased the living beings field effect, be conducive to the growth of crops.

Description of drawings

Fig. 1 is the novel structural representation of this use.

Fig. 2 is the vertical view of bract reducing mechanism shown in Figure 1.

Among the figure: 1, casing, 2, stationary knife, 3, moving knife, 4, cutter shaft, 5, gear, 6, movable knife disc.

Embodiment

As shown in Figure 1 and Figure 2, casing 1 is funnelform housing, upper and lower opening.Stationary knife group and movable cutter set are housed in casing 1; The stationary knife group is comprised of a row leg-of-mutton stationary knife arranged side by side, is fixed on the lopsidedness inwall of casing 1; Movable cutter set comprises cutter shaft 4, movable knife disc 6 and moving knife 3 etc., cutter shaft 4 is positioned at the centre of casing 1, be connected to by the bearing cross-brace on the sidewall of casing 1, at one group of movable knife disc arranged side by side 6 of cutter shaft 4 sockets, on the positive and negative two sides of each movable knife disc 6 moving knife 3 be installed all.Among Fig. 1, the knife face of moving knife 3 is triangle, is evenly equipped with three moving knife 3 in every one side of movable knife disc 6, the duty of pulverizing continuously to form multitool.Among Fig. 2, the blade part of stationary knife 2 extend between the fixing moving knife in movable knife disc 6 two sides in the formed crack, the situation of shearing to form twolip.

An external part at cutter shaft 4 is equipped with gear 5, with corn picker on power drive mechanism join the driving force of pulverizing to obtain rotation.

Claims
