Description

The dual-purpose hay cutter of small-sized convenience

The utility model relates to agricultural machinery technological field, is specifically related to the dual-purpose hay cutter of a kind of small-sized convenience.

The hay cutter that existing market is sold all is to be power with threephase motor or diesel engine, the most of casting of parts, feed shaft is gear drive, have that precision requirement height, power consumption are big, function singleness, body heaviness, waste raw material, maintenance difficulty is big, use inconvenient, especially at present power shortage, and each family does not possess the three-phase electrical source of power again, makes troubles to the user.

The purpose of this utility model provides that a kind of body is light, energy-conservation, manufacturing is simple, easy to maintenance, function is many, is the dual-purpose hay cutter of small-sized convenience of power with common 220 volts of mains lighting supplies, single-phase motor.

The utility model is achieved in that mainframe made by common angle steel, and precision requirement is not high, and power motor adopts Single-machine motor, has made things convenient for family's use; Charging driving wheel and driving wheel all adopt belt transmission, and having solved prior art charging wheel is the shortcoming of gear drive mounts rapid wear; Main shaft is directly installed on the mainframe, the middle frame position of prior art is the charging roller bearing, cuts the hand hay cutter main shaft with being installed on the casting integrated middle frame that the expense of taking a lot of work expects that the utility model is divided into two parts with middle frame, main shaft is directly installed on the mainframe, makes simple, easy to maintenance; In order to make hay cutter have the function of reconditioning cutter, at an end of main shaft emery wheel is installed directly, can conveniently repair with emery wheel and waste other agricultural machinery cutlery; Over cap is to make with common iron plate, has solved the shortcoming that material was taken a lot of work, taken in the manufacturing of prior art cast iron; The gear hobbing bracing strut is to make with simple foundry goods, makes simple, easy for installation.

The utility model is described in further detail below in conjunction with accompanying drawing

Fig. 1 is the utility model structural representation

Fig. 2 cuts organigram in the hand hay cutter case

Fig. 3 is a material feeding box structure cross-sectional schematic

Referring to accompanying drawing 1, mainframe 1 is made by common angle steel welding, and power motor 2 is installed under the frame, and motor adopts monophase machine, is fit to the 220V of family power supply and uses; Charging driving wheel 4 and driving wheel 8 all adopt belt transmission; Main shaft 13 directly is installed on the mainframe 1 by axle casing 11, at an end of main shaft 13 emery wheel 3 is installed directly, feed roller gear-box 6 is installed on mainframe 1 side by side and cuts hand hay cutter case 9, and its over cap 7 is to make with common iron plate; There is feed hopper 5 front portion at charging gear hobbing axle box 6, and discharging opening 10 is arranged at the bottom of cutting hand hay cutter case 9, and the drive 12 on the main shaft 13 drives charging driving wheel 4 by belt and rotates.

Referring to Fig. 2, an end of main shaft 13 is installed driving wheel 8, and the other end is installed emery wheel 3, and it is by gland 17 and fall female 18 fixingly, at main shaft 13 middle parts knife rest 14 and blade 15 is housed, and blade 15 usefulness screws 16 are fixed; Bearing box 11 and power transmission shaft 16 also are housed on main shaft 13.

Referring to Fig. 3, positive and negative gear hobbing axle 20 is housed in the material feeding box, the one side is equipped with built-up gear 22, gear hobbing bracing strut 21 is to be made by simple foundry goods, itself and the combination of watt box 19 usefulness Bolt Connection, prior art is that watt box and gear hobbing bracing strut are monoblock cast, makes complicated, inconvenient maintenance.

The utility model has the advantages that: make simple, cost is low, body is light, energy-conservation sturdy and durable, convenient many Function, practical etc.
