Abstract

The utility model relates to a combined cutting device without a blade protector, which comprises a fixed cutter which is arranged on a beam and a movable cutter riveted structure which is matched with the fixed cutter and is composed of a cutter bar and a movable cutter, and the beam is also provided with a blade pressing device and a friction plate to be matched with the movable cutter. The utility model is characterized in that the beam is a fixed cutter beam, and the fixed cutter is directly riveted with the front part of the fixed cutter beam. In the utility model, the fixed cutter is directly riveted with the front part of the fixed cutter beam, so that the blade protector and the blade protector beam are not used, the structure is simplified, and the manufacturing cost is obviously lowered. The utility model simultaneously takes the advantages of a standard V type cutter and a standard VI type cutter by the selection and match of component types, so the limitations and the shortages of the range of use of the V type and the VI type cutters are solved, so that the combined cutting device without a blade protector has a good cutting effect on thin stalk corps, such as wheat, paddy rice, soybean, etc., and thick stalk corps, such as maize, etc. The utility model has the advantages of high cutting efficiency, orderly cut, light weight and low cost.

Description

A kind of compound no guard cutter sweep

Technical field

The utility model relates to a kind of cutter sweep, mainly is suitable for the results cutting of wheat, paddy rice, soybean, seeding corn and other crops straw.

Background technology

At present, the reciprocating machine cutter that is used on the agricultural harvesters has six kinds of forms, and the I type is used for mower, and II type, III type, IV type all are applicable to the compound harvest machinery, and V-type is applicable to small-sized harvest machinery, and the VI type mainly is applicable to half-feeding combine.In order to prevent that the field barrier from causing damage to cutting knife, above-mentioned cutter all need dispose guard, stationary knife and guard all is contained on the finger beam complex structure, manufacturing cost height.In addition through facts have proved, the V-type cutter all has excellent adaptability on small-sized wheat and paddy reaper and small-sized grain combine, and in light weight, and general medium-sized and small enterprises can both produce, but the cutting to thick bar crop such as soybean, corn is yielding, poor reliability; VI type cutter has excellent adaptability on small-sized wheat rice soybean grain header, reliability height, but manufacturing cost height are gathered around down phenomenon to thick being cut with of bar crop such as corns, and be smooth inadequately.

Summary of the invention

The purpose of this utility model provides a kind of compound cutter sweep that does not have guard, thereby simplifies its structure and reduce manufacturing cost.

The purpose of this utility model also is by the apolegamy to models such as stationary knife, moving knife, guard, knife bars, makes its results that can be used for wheat, paddy rice, soybean, seeding corn and other crops straw simultaneously cutting.

For achieving the above object, the technical solution adopted in the utility model is: a kind of compound no guard cutter sweep, comprise the stationary knife that is contained on the beam and the moving knife riveted of forming by knife bar and moving knife that matches with stationary knife, on beam, pressuring blade device is housed also and friction plate matches with moving knife, described beam is the stationary knife beam, and stationary knife directly is riveted on stationary knife beam front portion.

Described friction plate comprises upper friction plate and following friction plate, upper friction plate, following friction plate and the pressuring blade device rear end stacks from top to bottom successively and be fixed in stationary knife beam rear portion by securing member, the moving knife riveted is contained on the stationary knife beam by following friction plate, upper friction plate and pressuring blade device, and the moving knife rear end is by friction plate supporting down.

As a kind of better embodiment of the present utility model, described stationary knife adopts standard I II type ledger-plate, and moving knife adopts standard I II type knife section, and pressuring blade device adopts standard V-type pressuring blade device, upper friction plate adopts standard I II type upper friction plate, and knife bar adopts the standard I type knife bar.The spacing of adjacent ledger-plate is 76.2mm, and fixedly the position dimension in pressuring blade device hole is got 76.2mm and 36mm.

The utility model directly is riveted on stationary knife beam front portion with stationary knife, has saved guard and finger beam, and structure is simplified greatly, and manufacturing cost obviously reduces.By apolegamy to number of element types, make it draw the advantage of standard V-type and VI type cutter simultaneously, solve the limitation and the deficiency of the above cutter scope of application, to the cutting of thin bar crop such as wheat, paddy rice, soybean or to the cuttings of thick bar crops such as corn good result of use is arranged all no matter be, and cutting efficiency height, it is neat to cut stubble, and in light weight, low cost of manufacture has broad prospect for its application.

Embodiment

As shown in Figure 1, 2, by rivet 10 with 9 rivetings of standard I II type ledger-plate in stationary knife beam 1 front portion, friction plate 3, standard I II type upper friction plate 4 and standard V-type pressuring blade device 7 are housed down on the stationary knife beam 1, upper friction plate 4, following friction plate 3 and pressuring blade device 7 rear ends stack from top to bottom successively and be fixed in stationary knife beam 1 rear portion by securing

member

11,12,13,14 are being equipped with pad 2 between friction plate 3 and the stationary knife beam 1 down; Standard I II type knife section 8 by rivet 5 with its riveting on standard I type knife bar 6, the moving knife riveted is contained on the stationary knife beam 1 by friction plate 3, standard I II type upper friction plate 4 and standard V-type pressuring blade device 7 down, moving knife 8 rear ends are by friction plate 3 supportings down.Shown in Fig. 3,4, the stationary knife beam adopts the Q235A steel of GB/T700 regulation to make, its key dimension does not adopt the size of standard VI stationary knife beam (JB/T7862.2-2001), especially the spacing of two ledger-plates does not adopt 50mm and adopts 76.2mm, fixedly pressuring blade device hole site size is got 76.2mm and 36mm, and ledger-plate 9 adopts standard I II type ledger-plate.Stationary knife beam 1 plays supporting and is connected effect, and standard I II type knife section 8, standard I type knife bar 6 and rivet 5 are formed the moving knife riveted; Following friction plate 3, standard I II type upper friction plate 4 and standard V-type pressuring blade device 7 guarantee that cutting gap is correct, and the moving knife riveted moves back and forth, and realize the smooth cutting of crop straw.

The advantage, the particularly distance between the ledger-plate that the utility model cutter sweep is drawn standard V-type and VI type cutter do not adopt standard VI type apart from 50mm, and adopt 76.2mm, thereby satisfied smooth cutting thick bar crops such as corns; For cooperating unique stationary knife beam and ledger-plate configuration structure, the moving knife riveted does not adopt standard VI type and adopts the standard V-type; Pressuring blade device does not adopt standard VIa type and adopts the standard V-type; Following friction plate thickness adopts standard Va type friction plate thickness, and its appearance and size and connecting hole size adopt friction plate size under the standard I II type; Upper friction plate has been guaranteed the adaptability of this cutter sweep to the cutting of thickness crop straw thereby upper friction plate adopts standard I II type, makes its compact conformation, uses reliable, in light weight, low cost of manufacture.
