Abstract

The utility model relates to a stalk cutter. The utility model is composed of a gear deviator, a candied gourd string-shaped chopping mechanism, a supporting fork cutting table grate, a pickup fork, and a stuff transferred roller, wherein, the chopping mechanism is provided with alternate circular saw blades. The string-shaped alternate circular saw blade chopping mechanism is arranged at the lower part of a gear box, and the distance between the saw blades and the floor is 15 centimeters. The pickup fork is arranged at the lower part of the stuff transferred roller, and stuff transferred roller is connected with the pickup fork are connected at the front part of the cutting table grate. A small tractor is regarded as the matching power, wherein, the horsepower of the tractor is more than 10. The stalk chopping is realized by that the cut stalks are picked up automatically, the stalks are conveyed to the rotating strip-shaped circular saw blade position to cut, and then, the stalks are discharged out. The utility model has the advantages that the structure is simple, the matching power is minimal, the efficiency is high, the chopping can be finished one time and the chopping is thorough and short. The utility model is suitable for farmers to harvest and cultivate.

Description

Stalk cutter

The utility model relates to a kind of stalk cutter, belongs to agricultural machinery.

Widely used stalk cutting and returning machine in present rural area and so on, can be divided into fixed and portable two kinds substantially, when fixed stalks cutting uses in the farmland, need stalk to be picked up and take in one's arms, near more will embracing at a distance, one a handle filled in the machine again with people, inevitable people will pay heavy muscle power, and efficient is low again, in case need be mobile very inconvenient, the human and material resources waste is greatly; Movable type then needs more powerful large sized tractor to drive, general minimum more than 50 horsepowers, the cost height, oil consumption is many, the chopping effect is uneven in length, and all stalks of all tires institute splenium branch can't be cut at all, very undesirable, directly make to cultivate and bring many troubles and inconvenience to the peasant.

The purpose of this utility model is at above-mentioned existing technical disadvantages, provide a kind of simple in structure, cost low can with) 10 horsepowers of supporting uses of numerous small four-wheel tractors, the chopping effect is once finished not only thoroughly but also is short, convenient peasant's results and cultivating are fit to the stalk cutter that the numerous individual dealers of agricultural machines in rural area use.

The utility model is realized in the following manner: stalk being cut down for convenient results the peasant is preceding topic, because the propelling of tractor, the straw field pickup fork is arranged before it, after flush with ground is picked up stalk automatically, through failing to expect to roll stalk is delivered to the saw blades groups place, garden that the interval intermediate plate is arranged respectively that is sugarcoated haws string shape (shape) rotation, it is broken to cut (saw) because centrifugation effect, be discharged to machine immediately after.The utility model is the preceding whippletree that utilizes tractor, will advance adjustable shelf to be contained on the preceding whippletree, connects this machine again, utilizes the power of the diesel engine belt pulley on the small tractor, finishes the entire job process.

Below in conjunction with drawings and Examples the utility model is further described:

Fig. 1 is a structure schematic top plan view of the present utility model.

Fig. 2 looks schematic diagram for a structure of the present utility model left side.

Fig. 3 looks schematic diagram for the structure of the present utility model right side.

Among the figure: 1 shell, 2 gear-boxes, 3 break-in relay axles, 4,5,7,8,9 bearing blocks, 6 bearing axle seats, 10,11,12,13 belt pulleys, 14 garden saw blade string working shafts, 15 defeated material roll, and 16 pick up fork, and 17 support forks are cut the platform grate, 18 gears, 19 advance adjustable shelf, 20 expansion tightening wheels, 21 garden saw blades, 22 wireline pulleys, 23 steel wire ropes, 24 driving shafts, plate in 25 supportings, 26 connect string pin hanger.

The break-in structure has in Fig. 1: gear-box 2, gear 18, driving shaft 24, break-in relay axle 3, bearing block 4, belt pulley 10,11 is formed, because the reverse running of diesel engine drives driving shaft 24, be forward running through the 18 meshing parallel break-ins of two gears, transmit through relay axle 3, thereby changed the direction of rotation that working shaft and defeated material roll, reached the purpose of required direction of rotation.Shredder mechanism has: garden saw blade string working shaft 14, supporting shaft holder 6 in center fixed on back skeleton on the shell, both sides are that sugarcoated haws string shape (shape) is spaced respectively to be contained in garden saw blade and Working-Clip sleeve on the working shaft, secondly are down to be fixed on the middle plate at two ends, below of deviator and belt pulley 12 constitutes along nut and bearing block 5,7.Pick up and the structure for conveying of stalk have: be fixed on support fork cut platform grate front lower place pick up fork 16 because of advance together stalk is picked up after, roll 15 by resistance and the crowded stalk that makes near defeated material, defeated material roll pick up fork above bearing block through two ends be fixed on the middle plate on both sides, because of rolling, defeated material is the triangle cage, under turning effort, pull over support fork of stalk is cut platform grate 17 places, the support fork is cut the front lower place of platform grate at the garden saw blade, around the saw blade gap except that middle and shell back skeleton support, two ends are fixed on the middle plate, because the grate tooth word order that support fork is cut the platform grate interlaces with sawtooth between the saw blade of garden and overlaps, making stalk lean on the string spaced garden saw blades groups that is of rotation, stalk to be cut (saw) broken, after being discharged to machine immediately, finish whole chopping process.

Propelling activity and positioning operation and the device that stops operation: advance adjustable shelf 19, adopt the characteristic of parallelogram, connect hanger with four and be connected the connection of the full application activity string of hanger pin with four of the present utility model.Positioning operation adopts the oil pressure elevating function of tractor self, through steel wire rope 23 around to after under the firm corbel back slab through left and right sides spreader pulley, be fixed on the lifting arm; The utility model dropped to pick up the fork job position that lands, make expansion tightening wheel 20 tensioner belts carry out operation simultaneously, rise and then stop operation.

The utility model has the advantages that: structure uniqueness, simple, the outward appearance novelty operate reliable and securely, uses clever It is convenient to live, and supporting power is minimum, can follow numerous mating miniature tractors, saving resource and energy consumption, cost is low, Efficient height, chopping effect are once finished thoroughly and are lacked, and convenient peasant gathers in the crops and cultivates, and is best suited for vast agricultural machinery The stalk cutter that use at the family.
