Abstract

The utility model relates to a splashing preventing device for a cutting table of a combine, which is characterized in that a clairvoyant splashing preventing cover with a shape which is similar to a ball net of a football court is arranged above the rear part of a material bunker of a cutting table. The device achieves the zero loss of rice and wheat in the material bunker of the cutting table, and the utility model can also ensure that an operator can observe the working conditions of each component in the material bunker of the cutting table and the conditions at the front of the cutting table at any time.

Description

The combine harvester cutting table anti-splash device

The utility model relates to a kind of anti-splash device that prevents that the rice wheat from spilling in the combine harvester cutting table hopper.

Combine is a kind of agricultural machinery efficiently, but is difficult to promote in China, and its one of the main reasons is that its nominal loss rate is higher.Even also unresolved good this problem of the combine that has good quality succeeded in developing of China in recent years, as the specified total loss rate that originates in all feeding-in combine in Taizhou, Zhejiang is: paddy rice≤3.5%, wheat≤2%; The specified total loss rate that originates in the rice/wheat combine of Guilin is: paddy rice≤3%, wheat≤2%.Practice shows, if misoperation, its total loss rate also can be much higher than specified total loss rate.Practice shows that also sizable rice wheat loss also has part because straw shift wheel gets rid of grass and causes because the rice wheat spills from ceding of Taiwan hopper rear side and causes.On frame for movement, the loss that loss that ceding of Taiwan hopper causes and straw shift wheel cause all causes owing to ceding of Taiwan hopper design is unreasonable.According to theoretical, the higher position that ceding of Taiwan hopper design gets enough can realize that the rice wheat zero in the hopper loses, can produce a series of problems again but ceding of Taiwan hopper design is too high, can not find in time whether cutter blocks, whether ceding of Taiwan front portion has foreign matter or not pile up have crop, ceding of Taiwan feeding mouth place screw feeder whether to turn over grass or screw feeder the problem that very likely causes mechanical accident such as whether to stop up as operating personnel.

The purpose of this utility model is to overcome the deficiencies in the prior art, design a kind of rice wheat zero loss that can realize in the ceding of Taiwan hopper, can guarantee that again operating personnel can observe the working condition of each parts in the ceding of Taiwan hopper and the combine harvester cutting table anti-splash device of ceding of Taiwan the place ahead situation at any time.

The utility model is achieved in that

A kind of combine harvester cutting table anti-splash device relates to ceding of Taiwan hopper, is loaded on the screw feeder in the ceding of Taiwan hopper, is positioned at straw shift wheel, the delivery chute of ceding of Taiwan hopper top, it is characterized in that upper lateral part also is provided with the splash guard that can have an X-rayed behind ceding of Taiwan hopper.Described splash guard can be upright flat shape, can be the inclined-plane or the arc shape that slightly tilt in ceding of Taiwan hopper, or the combination of upright plane, inclined-plane or cambered surface.

Further scheme is, splash guard is made of bracing frame and the sieve sheet that stretches tight on bracing frame.

Further scheme is, the one or both sides of anti-splash device also are provided with side plate.

Further scheme is that side plate is thin-wall boards or sieve sheet again.

Best scheme is to locate also to be hinged with splash guard above ceding of Taiwan hopper back side panel outer wall is positioned at the delivery chute inspection socket.

In the utility model, the described splash guard of having an X-rayed is except that can be with metal or the nonmetal sieve sheet, and also available other transparent or translucent material is made, as organic glass, plastic film etc.Traditional bucket of mixing adds retaining seat shape, and the net shape that is similar on the football field all is ideal forms of splash guard.

The utility model has the advantages that:

1, the rice wheat zero that can realize substantially entering in the ceding of Taiwan hopper loses.

2,, operating personnel are observed working condition and ceding of Taiwan the place ahead situation of each parts in the ceding of Taiwan hopper and just do not have influence substantially as long as often keep splash guard neatly intact.

3, the cost of the parts that increased is atomic, and the work and the maintenance of complete machine do not hindered.

4, make simply.

5, this device is applicable to various all feeding-in combines.

Fig. 1 is the vertical view of the assembling schematic diagram of associated components of the present utility model;

Fig. 2 is the A-A cutaway view of Fig. 1;

Fig. 3 is the schematic perspective view of an embodiment of splash guard.

Below, in conjunction with the accompanying drawings the utility model is described further.

As Fig. 1, Fig. 2 and Fig. 3, a kind of combine harvester cutting table anti-splash device, relate to the splash guard 5 that a shape is similar to the football field net, this splash guard 5 comprises bracing frame 6 that angle steel is welded into, stretch tight in the metallic screen sheet 7 of bracing frame 6 tops and rear side and be fixed in the thin-wall metal plate 8 of bracing frame 6 left and right sides, between bracing frame 6 and the metallic screen sheet 7 and between bracing frame 6 and the thin-wall metal plate 8 all with press strip 10 compactings and fastening with screw.Splash guard 5 back side lower parts are fixed in ceding of Taiwan hopper 1 back upper lateral part by screw, gap d slightly between the revolution circumference of the straw shift wheel above the ceding of Taiwan hopper 13 and splash guard 5 top front ends, screw feeder 2 is housed in ceding of Taiwan hopper 1, and the discharge end of screw feeder 2 is communicated with the feed end of delivery chute 4.Because the feed end top of delivery chute 4 also is provided with inspection socket, so locate also to be hinged with sideboard 9 above ceding of Taiwan hopper 1 back side panel outer wall is positioned at inspection socket.

Its splashproof principle is:

When the rice wheat particle in the ceding of Taiwan hopper 1 splashes outside ceding of Taiwan hopper 1, splash guard 5 will make the rice wheat particle ceding of Taiwan hopper 1 that rebounds back.

When part rice wheat particle when delivery chute 4 inspection sockets spill, sideboard 9 also can make rice wheat particle rebound back in the delivery chute 4.

When straw shift wheel 3 moving teeth were hung grass, suitable gap d can be scraped it into ceding of Taiwan hopper 1 by the angle steel of splash guard 5 top front ends again.
