Description

The double-deck cutter sweep of combine

The utility model relates to a kind of cutter sweep, particularly be the double-deck cutter sweep of a kind of improved combine.

People's custom is made the main frame of combine with tractor.As adopting Chuan Feng-15 type tractor with small four wheels to make the combining machine host, disadvantage is that main frame power is little, about 11.03KW.Other type is as 180 types, Mount Taishan-30 type, and the main frame of Shenniu-25 type etc. is all about 20～40KW.Only be provided with a cutting bed on the combine, in the harvesting process, operating condition is more abominable, the cooling system condition of work of tractor engine worsens and causes that the water in the engine water tank seethes with excitement, so little four-wheel combine is prone to the phenomenon of obstruction and the boiling of water tank water when farm work.

In view of above reason, the purpose of this utility model is in order to overcome above shortcoming, and a kind of double-deck cutter sweep of combine that can carry out operation easily in the harvesting process that is used on the combine is provided.

The purpose of this utility model is achieved in that ceding of Taiwan drive (1) in the utility model cutter sweep, one end is loaded on the connecting rod (2) on the ceding of Taiwan drive, contain the ceding of Taiwan (6) of upper cutter knife group (12), one end is connected with the ceding of Taiwan and by ball head connecting rod (9), the top link (7) that bearing shell (10) and flexible bulb (11) are connected with upper cutter knife group (12), the other end that it is characterized in that connecting rod (2) is connected on the bearing shell (3), flexible bulb (4) is housed in the bearing shell (3), flexible bulb (4) is fixedly connected with swing arm axis (5), the top of swing arm axis is stretched in the top link and is fixedlyed connected with top link, the bottom of swing arm axis is fixedly connected with the following swing arm (8) that is loaded in the ceding of Taiwan, ball head connecting rod (13) one ends are connected down flexible bulb (15) are housed in the bearing shell on the other end (14) in the swing arm, and flexible bulb (15) is connected with the following cutter group (16) that is loaded in the ceding of Taiwan (referring to Fig. 1～Fig. 5).

The fixed block (18) that contains regulating tank is arranged in the above-mentioned ceding of Taiwan, connector passes adjustment hole on back supporting rod (20) one ends and the regulating tank on the fixed block makes back supporting rod slide and be fixed on the fixed block along regulating tank, the front portion of back supporting rod is connected on the following cutter group of ceding of Taiwan bottom, an end that contains the lifter plate (22) of several lift spans is connected the front portion of back supporting rod, and the lift span that connector passes back supporting rod is connected (referring to Fig. 4) in the ceding of Taiwan with lifter plate.

During the utility model work, ceding of Taiwan drive is with transmission of power and connecting rod, the reciprocal stretching motion of connecting rod makes the bearing shell that is attached thereto and the flexible bulb can be in direction swing up and down, thereby make the swing arm axis drive pumping arm action side-to-side movement on straight line, make the upper and lower cutter group that connects on it carry out side-to-side movement clocklike simultaneously.Because upper and lower swing arm is connected in upper and lower cutter group two places and all adopts bearing shell to be connected with flexible bulb, the side-to-side movement that makes it in cutting can be done flexible swing.In the course of the work, the rice wheat head that straw shift wheel at first will the row's of going up cutter need cut and bar are allocated to the upper cutter knife group and cut, and the rice wheat head after the cutting transfers to delivery chute through the spiral of screw feeder and carries out other system works.The upper cutter knife group is when cutting, because the effect of straw shift wheel makes the front and back cutting distance of upper and lower cutter differ 150～200mm, after the upper cutter knife cutting earlier, the rice straw is just left down cutter for and finished.Rice straw after the following cutter cutting is just stayed the field, has finished the whole operation process of the double-deck ceding of Taiwan.The utility model is delivered to down operation after the 300mm length of the rice wheat head can being allocated to cutter cuts with straw shift wheel.About 700～the 800mm of rice wheat length overall height has cut behind the 300mm and has finished with the cutter of bottom about the about 400～500mm of remaining height, stays the field after the unnecessary rice straw that needn't enter is cut off.Adopt this device, minimum altitude can be guaranteed about 90mm.Such condition of work can overcome being short of power of small tractor fully.

Compare with existing single layer cut platform, the utlity model has following advantage:

1, only increase a cutting bed, just can make the conveying capacity of the whole combine system that enters main frame obviously reduce (can reach 2/3), carry threshing, wind to send etc. for the running of complete machine supremacy clause is provided, just complete machine can carry out operation easily in the harvesting process, has avoided the generation of obstruction and water tank boiling phenomenon; Not only can gather in and bring into play its combine effect season, and can give full play to the effect advantage that other machine can not be finished season at rice harvest at wheat;

2, can disposablely finish the cutting work of wheat (rice) fringe and wheat (rice) bar;

3, weeds can be cut off and stay, and needn't use other weeder again in the field.

Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing:
