Abstract

The utility model belongs to the field of application of husbandry machinery and particularly relates to a feeding and chopping device of forage grass picking and conveying equipment. The feeding and chopping device comprises a power input shaft, a cutter rest, a driven crank, a shifting tooth rod, a crank disk, a rotary main shaft, cutters, a positioning handle, an upper cutter regulating button, a lower cutter regulating button, a coupling pin, a pull rod, a front cutter rest, a fixing rod and a tension spring. When the feeding and chopping device works, power is input through the power input shaft to drive the rotary main shaft and the crank disk to rotate so as to drive shifting teeth to rotate; and the cutters pass through seams of the shifting teeth so as to realize that forage grass is grabbed, chopped and conveyed to the next station. In the feeding and chopping device, a double-crank mechanism has a compact structure and makes reasonable motion; each cutter is provided with an overload protection device, so that the abnormal damage to each cutter is avoided and the parking caused by abnormal faults is reduced; and meanwhile, the feeding and chopping device has the function of selecting whether to use the cutters and regulate the length of each chopping segment of the forage grass.

Description

Forage grass is picked up the feeding shredding mechanism of transporting equipment

Technical field

The utility model belongs to farming and animal husbandry machine applications field, is specifically related to the feeding shredding mechanism that a kind of forage grass is picked up transporting equipment.

Background technology

Along with China's Developing of Animal Industry, the demand of forage grass is increased day by day.Along with plantation grassland area increases year by year, more and more higher simultaneously to the requirement of fodder grass mechanized harvest.Forage grass is picked up the appearance of transporting equipment, and, operating efficiency advantages of higher little with its yield loss received user's welcome, for the results of fodder grass with a kind of strong technical guarantee is provided.Simultaneously the fodder grass after the chopping is carried out ensiling, compacted density height, fast, little, the good palatability of nutritive loss of fermentation easily obtain the silage fodder of high-quality.

Summary of the invention

The utility model purpose is to provide a kind of novel forage grass feeding shredding mechanism, picks up the job requirements of transporting equipment to be fit to forage grass.

The utility model mainly is achieved through the following technical solutions:

A kind of forage grass is picked up the feeding shredding mechanism of transporting equipment, partly is made up of power input shaft, cutoff knife rack, passive crank, moving tooth bar, crank disc, rotary main shaft, cutting knife, position fixing handle, last toolsetting button, following toolsetting button, attachment pegs, pull bar, preceding cutoff knife rack, dead lever, extension spring etc.Power input shaft, crank disc and rotary main shaft are fixedly connected, and it is hinged that power input shaft and forage grass are picked up transporting equipment, and cutoff knife rack, dead lever and forage grass are picked up transporting equipment and is fixedly connected, cutting knife one end and cutoff knife rack is hinged, an end is held by extension spring.

The utility model is installed in forage grass and picks up on the transporting equipment, power is imported by power input shaft during operation, driving rotational main shaft, crank disc rotation, thus drive the rotation of moving tooth bar, cutting knife passes from moving tooth bar webs, thereby realize to grasp forage grass, with forage grass chopping and be delivered to next station.

Description of drawings

Fig. 1 picks up the feeding shredding mechanism axonometric drawing of transporting equipment for forage grass.

Fig. 2 picks up the feeding shredding mechanism profile of transporting equipment for forage grass.

In the accompanying drawing: cutoff knife racks, 14 dead levers, 15 extension springs before toolsetting button on 1 power input shaft, 2 cutoff knife racks, 3 passive cranks, 4 moving tooth bars, 5 crank discs, 6 rotary main shafts, 7 cutting knifes, 8 position fixing handles, 9,10 times toolsetting buttons, 11 attachment pegs, 12 pull bars, 13.

Embodiment

The utility model will be further described with reference to the accompanying drawings:

A kind of forage grass is picked up the feeding shredding mechanism of transporting equipment, partly is made up of power input shaft 1, cutoff knife rack 2, passive crank 3, moving tooth bar 4, crank disc 5, rotary main shaft 6, cutting knife 7, position fixing handle 8, last toolsetting button 9, following toolsetting button 10, attachment pegs 11, pull bar 12, preceding cutoff knife rack 13, dead lever 14, extension spring 15 etc.Power input shaft 1, crank disc 5 are fixedly connected with rotary main shaft 6, it is hinged that power input shaft 1 and forage grass are picked up transporting equipment, cutoff knife rack 2, dead lever 14 picked up transporting equipment with forage grass and is fixedly connected, and cutting knife 7 one ends and cutoff knife rack are 2 hinged, an end is held by extension spring 15.Preceding cutoff knife rack 13 1 ends and cutoff knife rack 2 are hinged, and an end is hinged by attachment pegs 11 and pull bar 12.Power is imported by power input shaft during operation, the rotation of driving rotational main shaft, crank disc, thus driving the rotation of moving tooth bar, cutting knife passes from moving tooth bar webs, thereby realizes grasping forage grass, with forage grass chopping and be delivered to next station.

Dead lever 14 in the utility model, crank disc 5, a passive crank 3 and the moving tooth bar 4 that links to each other constitute double-crank mechanisms, three double-crank mechanisms are uniform at the circumferencial direction that with rotary main shaft 6 is the center, wherein dead lever (14) and forage grass are picked up the transporting equipment frame and are fixedly connected, be provided with on each moving tooth bar many to moving tooth, the corresponding cutting knife of the every pair of moving tooth.By determining the technical parameter of each parts, make the movement locus of moving tooth 4 and speed characteristics be fit to grasp forage grass, chopping forage grass, and the forage grass after will shredding is delivered to next station.

The utility model can select whether to use the chopping function, and when not using the chopping function, rotational positioning handle 8 uses special spanner to press down toolsetting button 9, puts down cutoff knife rack 2, unloads lower cutter 7, mentions cutoff knife rack 2 again, rotational positioning handle 8 fixed cutting tool framves 2.

Two row's cutting knifes 7 before and after the utility model is provided with, whether wherein front-seat cutting knife 7 can be selected to use easily, obtains needed herbage staple fiber ppd.When needs will be than long forage grass staple fiber ppd, attachment pegs 11 can be taken off, use special spanner to press down down toolsetting button 10, another pin-and-hole on the current cutoff knife rack 13 and the pin-and-hole on the pull bar 12 over against the time attachment pegs 11 is installed, front-seat cutting knife 7 can be retreated to the below of cutoff knife rack 2, front-seat cutting knife is no longer worked.

Each cutting knife 7 all is provided with overload protection arrangement in the utility model.When cutting knife 7 ran into harder foreign matter or bigger cutting resistance, cutting knife 7 was recovered to cutoff knife rack 2 belows automatically during work, and god is drawn in extension spring 15, treat foreign matter by or after the cutting resistance reduced, cutting knife returned to original operating position under the effect of extension spring 15 pulling force.
