The utility model belongs to the technological improvement of a profile modeling low cutting device of an agricultural harvesting machine. The utility model is characterized in that the utility model is provided with profile modeling cutter racks, and the front ends of which are provided with cutting mechanisms. The back ends of the profile modeling cutter racks are connected with a header by a hinge, and the lower sides of the profile modeling cutter racks are provided with trailing bars. The upper sides of the profile modeling cutter racks are suspended on a fixed bracket by a spring, and the profile modeling cutter racks and the cutting mechanisms are respectively one group right and left. A transmission mechanism drives the cutting mechanisms from the middle of the two groups. The utility model has sensitive profile modeling, and cutter monomer floats freely. When the utility model works, the utility model can not generate soil gathering and carrying phenomena, and the utility model accomplishes low stubble reaping and reduces grain loss.

Description

Soybean combine profiling close mowing mechanism

The utility model belongs to agricultural machinery technological field, is specifically related to the improvement of combining diced system close mowing technology.

Domestic existing combine, particularly middle-size and small-size backpack combine, the cutting part of the ceding of Taiwan has generally been taked rigid the connection with the ceding of Taiwan, has the problem of close mowing performance deficiency.

1, because ceding of Taiwan school is heavy, and delivery chute and ceding of Taiwan syndeton are unreasonable, limited the performance of the whole profiling effect of the ceding of Taiwan, ceding of Taiwan planker and ridge body frictional resistance are excessive, produce and gather around soil, native phenomenon in the ceding of Taiwan.

2, the cutter part all is rigid the connection with the ceding of Taiwan, and not profiling of cutting part does not realize floating automatically close mowing, and it is consistent not guarantee to cut stubble.

3, the connected mode of the transmission mechanism of diced system can not satisfy cutter and moving reciprocatingly, and rises automatically simultaneously or descending motion.This is the deficiency of existing moving knife transmission mechanism bulb and connecting rod connected mode.

The purpose of this utility model is the profiling close mowing mechanism that a kind of and existing combine of design is complementary, to solve the problem of middle-size and small-size backpack combine harvester header profiling poor performance, solve single ridge (or many ridges) floating copying close mowing technical problem automatically, and then solve the problem that the ceding of Taiwan is gathered around soil, gone up soil.

The utility model is made up of copying tool post, cutting mechanism and transmission mechanism, the copying tool post front end is installed with cutting mechanism, the copying tool post rear end is connected with ceding of Taiwan hinge, planker is installed below the copying tool post, copying tool post top by spring suspended on fixed support.Copying tool post and cutting mechanism be about each one group, transmission mechanism drives cutting mechanisms in the middle of two groups.

Transmission mechanism: the eccentric drive wheel of the whole tying rod and the ceding of Taiwan links, hinged with the triangle swing arm, the triangle swing arm affects pull bar and rear-swing arm, drive balance staff left and right sides half turn, front swing arm by the balance staff front end is reduced into half turn and swings again, and front swing arm drives slide block, and a square hole respectively is with on the left and right both sides of slide block, the moving knife push rod of cutting mechanism is stretched in square hole, is stirred the moving knife left and right sides changing of the relative positions of cutting mechanism by square hole.

The course of work of the present utility model is by balance staff, slide block, transmission mechanism power to be passed to left and right sides moving knife push rod, makes left and right sides moving knife push rod do left and right sides linear reciprocating motion, thereby realizes cutting operation.In the motion, can produce relative displacement between left and right sides moving knife push rod and the slide block assembly.Therefore, transmission mechanism does not influence the cutter floating copying.

During operation, mix up the distance on the ceding of Taiwan and ridge top earlier, to guarantee that under profiling planker and the effect of hanging spring the relative ceding of Taiwan of cutter with the hinge point is that axle produces unsteady for feeler mechanism during close mowing.Thereby realize automatic individual profiling close mowing operation.This machine Single-ridge copying motion is not influenced by or not adjacent ridge, can develop into two ridges or many ridges profiling lower cutting installation on this architecture basics,

The utility model is installed in the header part of combine front end, and its transfer motion power source is still provided by combine, does not change the global design of combine.Compared with prior art, the one, the ceding of Taiwan and cutting mechanism are connected through the hinge, can solve existing ceding of Taiwan profiling poor, gather around soil, go up native problem, realize cutter monomer floating copying; The 2nd, can realize low stubble harvesting, do not stay " horse ear " fresh kidney beans; The 3rd, transmission mechanism has solved existing triangle centering block and has scraped the problem of facing ridge beans bar easily in central authorities; The 4th, reduced the grain loss rate.

Fig. 1 and Fig. 2 are same ratio, and Fig. 3 to Fig. 6 is put than Fig. 1 and Fig. 2 and is twice;

Fig. 1 is a front view of the present utility model;

Fig. 2 is that the A of Fig. 1 is to view;

Fig. 3 is that the B of Fig. 1 is to view;

Fig. 6 is that the E of Fig. 1 is to view.

Now in conjunction with the accompanying drawings, concrete structure of the present utility model is described below:

The utility model is connected by joint 15 hinges with the ceding of Taiwan 22 by two copying tool posts 14, and the front end of copying tool post 14 is installed with stationary knife 8 and 12, and moving knife 9 and 13 is installed in respectively on moving knife connecting plate 10 and 11.Bearing support 25 is fixed in the ceding of Taiwan 22, is installed with above the bearing support 25 to regulate bolt 27 and nut seat 16, hangs spring 28 1 ends and connects adjusting bolt 27, and the other end hangs on the copying tool post 14.21 are the hinge dragon in the ceding of Taiwan.

Transmission mechanism, power is imported into from ceding of Taiwan eccentric drive wheel by whole tying rod 33, the push-and-pull campaign of whole tying rod becomes to drive pin 5 through triangle swing arm 24, pull bar 23, rear-swing arm 18, balance staff 17 and front swing arm 42 and swings, drive slide block 3 and 6 about drive, drive in the slide block and have square hole 1, left and right sides moving knife push rod 2 and 7 stretches in the square hole, is cutting action with the square hole side-to-side movement, and the motion of phase time square hole is floated for the cutter profiling up and down.
