Description

A kind ofly be equipped with the grain header that secondary is cut batch device

Technical field

The utility model relates to a kind of grain header that wheat or cereal are gathered in, and especially a kind ofly is equipped with the grain header that secondary is cut batch device.

Background technology

Along with development of human society, science and technology constantly develops, and the instrument and equipment of electromechanical integration is more and more, and China is large agricultural country, and the kind of agricultural machinery is also more and more, and especially more quick and easy agricultural machinery constantly occurs.Wheat is one of main crops of China, and the harvesting of wheat is at present also gathered in by original craft and transferred mechanical harvesting to, bigger raising operating efficiency, saved manpower.Yet the mode of operation is once gathered in the many employings of existing grain header, promptly in wheat harvesting process, grain header is provided with a cutter, drives the cutter action by the power wheels, wheat is realized disposable harvesting, though this structure has improved operating efficiency,, make that the cutter amount of extracting is bigger because residual wheat stubble can not be too high, thereby harvesting speed is slower, and because the feed quantity that the harvesting amount causes follow-up stalk to handle greatly is big, efficient is low, the energy consumption height.

The utility model content

Be to solve the deficiencies in the prior art, the utility model provides a kind of and can raise the efficiency effectively and the outfit secondary of energy savings is cut the grain header of batch device, and it is simple in structure, and is easy to use.

For achieving the above object, the grain header that outfit secondary of the present utility model is cut batch device comprises body, is arranged on the upper cutter knife on the body, described upper cutter knife is by being fixedly installed on the power wheels driven in rotation in the body outside, on the body, upper cutter knife below be fixedly connected with down cutter, described cutter down is by being arranged on the power wheels driven in rotation in the body outside.

As the improvement of aforesaid way, on body, be installed with locating piece, be fixed with lifting arm on the following cutter, described down cutter by an end be fixed on lifting arm, the other end is positioned on the body by the leading screw that nut is fixed on the locating piece.

Further improvement as aforesaid way, this grain header also comprises hydraulic lifting mechanism, described hydraulic lifting mechanism is made up of hydraulic cylinder, connecting rod and oil circuit, and described hydraulic cylinder is fixed on the locating piece, and its clutch end links to each other with following cutter by connecting rod.

Adopt technique scheme, have following beneficial effect:

A, employing upper cutter knife only cut the wheat head, make the part of cutting that the wheat head and a spot of stalk only be arranged, for follow-up wheat head treatment process has been saved the energy; And because cutting quantity reduces, make the speed of the cutting wheat head improve, its efficient can improve 30%;

B, employing cutter are down carried out secondary cut to the stalk remainder, at first can determine cutting quantity according to the differing heights of the wheat head, and be easy to use, can make remaining stalk have suitable height when making straw-returning in addition, do not influence the farming of next time.

Description of drawings

Below in conjunction with the drawings and the specific embodiments the utility model is done further to describe in detail:

Fig. 1 is an overall structure schematic diagram of the present utility model;

Fig. 2 is the syndeton schematic diagram of cutter and body under the utility model.

Embodiment

By Fig. 1, as can be known shown in Figure 2, this outfit secondary is cut the grain header of batch device, comprise body 6, be arranged on the upper cutter knife 12 on the body 13, upper cutter knife 12 is by being fixedly installed on power wheels 10 driven in rotation in body 13 outsides, on body 13, be installed with locating piece 1, be fixed with lifting arm 2 on the following cutter 5, following cutter 5 is fixed on lifting arm 2 by an end, the other end is positioned on the body 13 by the leading screw 8 that nut 9 is fixed on the locating piece 1, and following cutter 5 drives the hundred ring casees 7 that are fixedly installed on down cutter 5 one ends by the power wheels 11 that are arranged on body 13 outsides and drives cutter 5 actions down.In addition, this grain header comprises two groups of hydraulic lifting mechanisms, and every group of hydraulic lifting mechanism is made up of hydraulic cylinder 3, connecting rod 6 and oil circuit 4, and described hydraulic cylinder 3 is fixed on the locating piece 1, and its clutch end links to each other with following cutter 5 by connecting rod 6.

During use, with upper cutter knife 12 as for stalk top, primer fluid cylinder pressure 3 is transferred connecting rod 6, until descending cutter 5 in the stalk appropriate location, to descend the position of cutter 5 to fix by nut 9, leading screw 8, drive upper cutter knifes 12 and following cutter 5 is worked by power wheels 10 and power wheels 11, upper cutter knife 12 is used for the wheat head is cut off, and the wheat head of cutting off is sent in the subsequent handling handle, following cutter 5 carries out secondary cut with stalk, realizes straw-returning.After the use, will descend cutter 5 to be promoted to the appropriate location by hydraulic lifting apparatus after, be fixed and get final product with nut 9, leading screw 8.It is simple in structure, and is easy to use, the efficient height.
