Abstract

The utility model relates to a small dual-purpose machine for cutting and crumbling grass. The existing grass cutter composed of an upper shell, a lower shell, a main shaft, a bearing seat, a belt pulley, a knife disc, knife blades and a knife table adopts an axial feeding mode, cuts grass in axial direction from inside to outside, needs greater rotary moment of inertia, and consumes large energy. In the utility model, the right side of the upper shell is provided with a feed port, and a radial feeding mode is used. The cross section of the outer part of the knife disc forms a T shape, and the outer round surface of the knife disc is provided with the two knife blades which are symmetrical to each other. The moment of inertia of rotation can be reduced with small energy consumption by adopting axial cutting. The lower shell forms a square cylinder shape, and a supporting plate is welded between two side walls of the lower shell. Two cambered toothed plates are respectively arranged between the supporting plate and the upper edges of the left and the right walls, and a sieve plate is arranged between the two toothed plates. The main shaft can rotate at high speed via the tower-shaped belt pulley with variable speed, and thus the utility model can be used as a pulverizer. The other end of the main shaft is also provided with a grinding wheel. The small dual-purpose machine for cutting and crumbling grass is particularly suitable for farmers' families to use.

Description

Miniature dual-purpose machine for cutting and disintegrating hay

The utility model belongs to agricultural machinery hay cutter class.

Existing hay cutter, form by upper shell, lower house, main shaft and bearing block, belt pulley, cutterhead, blade and cutter platform, this hay cutter be with blade apparatus on the side of cutterhead, on the sidewall of upper shell, have charging aperture, the cutter platform is fixed on the place, upper edge of lower house sidewall, axial admission, radially hand hay cutter is cut from inside to outside; The problem of this hay cutter is: axial admission, and radially hand hay cutter is cut from inside to outside, and the hand hay cutter point of contact is nearer from main shaft, and the hand hay cutter linear velocity of cutting is low excessively, requires the rotator inertia moment of cutterhead bigger, and energy consumption is more, and it is also lower to cut up with a hay cutter careless efficient.

The purpose of this utility model is: provide a kind of structure less, energy consumption is the end of than, the broken dual-purpose machine of rotator inertia moment small-sized hand hay cutter grass meal little, that efficient is high.

Technical measures of the present utility model are: the right side at upper shell has charging aperture, in the material mouth hopper is housed; Lower house is a square tube shape, and seam has 2 or 4 support plates between two sidewalls, between the support plate on right side and the You Bi upper edge, between the support plate in left side and the Zuo Bi upper edge arc tooth plate is housed respectively; The outside section of cutterhead is a T shape, and two blades of symmetry are housed on the outer garden of cutterhead; At main shaft one end the speed change tower-shaped belt pulley is housed; On the right wall of lower house, be fixed with the cutter platform.

The broken dual-purpose machine of small-sized hand hay cutter grass meal of the present utility model, right side at upper shell has charging aperture, change radially charging into by axial feeding, two blades of symmetry are housed on the face of the outer garden of cutterhead, blade is in axially cut up with a hay cutter on the position farthest, axle center and cuts, make cutterhead just can satisfy to cut up with a hay cutter and cut in less rotator inertia moment effect; Two arc tooth plates are housed in the lower house of square tube shape, refill a sieve plate at the place of eating dishes without rice or wine between two arc tooth plates, make the main shaft high speed rotating also can realize the effect of pulverizing; So broken dual-purpose machine of small-sized hand hay cutter grass meal of the present utility model; When grass hand hay cutter has rotator inertia moment little, and less energy consumption also has the good effect of cracker.

Fig. 1 is a structural representation of the present utility model, and Fig. 2 is an end view.

1 is upper shell among the figure, and the right side of upper shell has charging aperture, and hopper 3 is housed in the charging aperture, changes radially feeding into by original axial feeding; Lower house 6 is square tube shapes; Seam has 2 or 4 support plates 8 between two sidewalls of lower house, between the support plate 8 and You Bi upper edge on right side, between the support plate 8 in left side and the Zuo Bi upper edge arc tooth plate 7 is housed respectively, the effect of arc tooth plate 7 is to play pulverizing when transferring hay cutter to cracker.Two at lower house 6 are being supported main shaft 14 by two bearing blocks 13 above the sidewall, fix a cutterhead 2 on the main shaft 14, the outside section of cutterhead is a T shape, two blades 4 of symmetry are housed on the garden outside cutterhead, adopt axially to cut up with a hay cutter and cut, blade 4 is on main shaft 14 position far away, under the identical situation of cutterhead rotational angular, the position line speed far away apart from main shaft is big, this cuts for hand hay cutter is very favourable, utilize less rotator inertia moment just can satisfy the needs that hand hay cutter is cut, so energy consumption is lower.On the right wall of lower house cutter platform 5 is housed, the Zuo Bi bottom has grass outlet 11, Di Kouchu that base plate A is housed, and at main shaft 14 1 ends speed change tower-shaped belt pulley 16 is housed, and the other end of main shaft 14 is equipped with emery wheel 15, but abrasive dust blade 4 and kitchen knife, axe, reaping hook etc.When grass hand hay cutter, adopt low speed to make main shaft 14 rotations, grass radially feed through hopper 3, and blade 4 and cutter platform 5 be grass hand hay cutter section, section grass eating dishes without rice or wine between two arc tooth plates 7, grass outlet 11 discharges.When need are given pig processing powder ground feed, with grass outlet 11 shutoff, A moves with base plate, the place of eating dishes without rice or wine between two arc tooth plates 7 loads onto an arc screening plate 9, sieve plate 9 makes main shaft 14 high speed rotating by 10 tops of transverse axis by speed change tower-shaped belt pulley 16, and forage grass is earlier through blade 4 and cutter platform 5 hand hay cutter sections, section grass is scraped in blade 4 and resistance under the effect of device and is pulverized through arc tooth plate 7, and leak down in the hole of sieve plate 9 end mouth of housing 6 of pulverized forage grass is discharged.It is bolt 12 or the scraper plate that is fixed on the cutterhead 2 that device is scraped in above-mentioned resistance.The broken dual-purpose machine of this small-sized hand hay cutter grass meal mainly uses designed for farmers' family.
