This programme discloses a kind of forage cutting machine of field of agricultural machinery, including cutting box, and motor and two transmission shafts are equipped in cutting box, and two transmission between centers are socketed with transmission belt；It is fixedly connected with cam on the output shaft of the motor, the longer end of cam is arc surface, it is fixedly connected with cutter on the side of cam, cutter extend to outside the longer end of cam, cam is located at the surface of transmission belt, with transmission interband there are gap when cam longer end is located at minimum point, gap is less than forage thickness；The cutter are located at outside conveyer belt；The arc surface of the cam longer end is equipped with grinding tooth；The grinding tooth is engaged with worm screw；Worm screw is connect with the transmission shaft by belt.Forage cutting machine in this programme controls the Cutting Length of forage by the rotation of cam, to ensure that the forage length being cut into is unified.

Description

A kind of forage cutting machine

Technical field

The invention belongs to field of agricultural machinery, more particularly to a kind of forage cutting machine.

Background technology

Herding refers to the animal tamed by our human artificial raisings using poultry, fowl etc., Huo Zhelu, musk deer, fox, ermine, The physiological function of the wild animals such as otter, quail enables it to change the plants such as herbage and feed by artificial feeding, breeding For animal energy, to obtain the production process of the livestock products such as meat, egg, milk, wool, cashmere, hide, silk and medicinal material.In herding In breeding process, forage is often used as feed；And the forages such as stalk due to containing fiber it is more, length is larger, no Conducive to the edible of livestock and poultry and absorb；Therefore it before launching forage, generally requires and forage is cut.

Currently, the cutting of forage is mainly carried out by forage cutting machine, the relatively simple forage of structure is cut on the market at present Cutting mill includes mainly motor, and motor is fixedly mounted in rack, and motor is connect by belt gear with main shaft, main Axis is mounted on by bearing block in rack, and cutting tool is installed in one end of main shaft.Such be arranged is realizing the same of chaffcutter purpose When, it is cut due to needing to move forage with hand push so that cutting tool is easy to generate injury to human body；Simultaneously as forage Promotion mainly carried out using artificial, cause the push amount of forage in the unit interval indefinite, and then cause the Cutting Length of forage It is uneven.

Invention content

The invention is intended to provide a kind of forage cutting machine, cut in progress forage with solving forage cutting machine in the prior art When cutting, the problem of forage causes the forage length being cut into differ is pushed using artificial.

In view of the above technical problems, a kind of forage cutting machine that this programme provides, including cutting box, cutting box is interior to be equipped with electricity Machine and two transmission shafts, two transmission between centers are socketed with transmission belt；Be fixedly connected with cam on the output shaft of the motor, cam compared with Long end is arc surface, is fixedly connected with cutter on the side of cam, cutter extend to outside the longer end of cam, and cam is located at The surface of transmission belt, with transmission interband there are gap when cam longer end is located at minimum point, gap is less than forage thickness；It is described Cutter are located at outside conveyer belt；The arc surface of the cam longer end is equipped with grinding tooth；The grinding tooth is engaged with worm screw；Worm screw with The transmission shaft is connected by belt.

The operation principle and advantage of the present invention：In use, forage is put on a moving belt.Start motor, motor Output shaft band moving cam rotates, and the grinding tooth in cam longer end is engaged with worm screw drives worm screw rotation, worm screw that conveyer belt is driven to turn It is dynamic, and then the forage on conveyer belt is made previously to move.When cam goes to lower section, worm screw disengaging is engaged with cam, cam When longer end turns to lower section, cam longer end is pressed against forage, while cutter cut forage.Such Zhou Erfu Begin, since the amount of cam driven worm movement is certain, so that the amount that conveyer belt drives forage previously to move is certain, and then cuts Cutter is certain to the Cutting Length of forage.Meanwhile forage is placed in transmission belt i.e. by direct in this programme by certain way Can, it need not equally need that forage is manually pushed to advance to forage cutting machine in the prior art, and then avoid cutter pair The case where staff damages.

Further, one end of the transmission belt is located at outside the cutting box.Transmission belt is arranged outside cutting box, convenient for grass The addition of material, while whether normal operation convenient for observation cutting machine.

Further, the cutting box includes bottom plate, and bottom plate is equipped with discharge hole, and discharge hole is located at the underface of cutter. It is convenient for the collection of forage by the way that discharge hole is arranged, avoids the normal operation of forage bulk deposition operation cutting machine in cutting box.

Further, the bottom of the cutting box is equipped with idler wheel.By the way that idler wheel is arranged, it is convenient for the movement of cutting box.
