Abstract
A lower cutter mechanism for a small-sized grain combine-harvester belongs to the field of agriculture machinery and main comprises a left supporting arm, a shifting base, a moving cutter, a fixed cutter and a right supporting arm. The left supporting arm, the right supporting arm and the fixed cutter are designed into a whole, a mounting table and a reinforcing rib are arranged at the corner position, a moving cutter handle is designed on the moving cutter, and the moving cutter and the moving cutter handle are designed into a whole. The lower cutter mechanism is characterized in that the shifting base and the mounting table are arranged between the upper face and the lower face of the fixed cutter, the upper face and the lower face of the fixed cutter are in an arc shape, the upper face and the lower face are of a symmetrical structure, the shifting base is mounted on the mounting table through a pin shaft, one end of the shifting base is connected with an operation rod, and the other end of the shifting base is connected with the moving cutter handle on the moving cutter. The lower cutter mechanism for the small-sized grain combine-harvester reduces the grass concentration phenomenon of the lower cutter. Meanwhile, compared with a design manner that the supporting arm is arranged on the inner side of a track, stability and strength of the lower cutter is reinforced, and maintenance and overhaul in a later stage are facilitated.
Description
Technical field
The utility model relates to a kind of rice/wheat combine, relates in particular to cutter knife mechanism under a kind of small-sized rice/wheat combine, belongs to agricultural mechanical field.
Background technology
Cutter on rice/wheat combine has two kinds, one is referred to as upper cutter knife, one is referred to as lower cutter, the effect of upper cutter knife is that the crops such as the rice wheat point of raising is cut off to rear threshing, lower cutter is upper cutter knife to be cut to surplus standing grain stubble level land cut off, meet and plough again the requirement of planting again, lower cutter of the prior art has two kinds of arrangements: a kind of mode is outside and the front that lower cutter support arm exposes to crawler belt, the drawback of this mode is that support arm has the careless phenomenon of extension, lower knife strap has the careless phenomenon of collection, collection grass easily pushes over the crops of not cutting off in front and causes the loss of standing grain fringe, another kind is for above-mentioned shortcoming, support arm is arranged in crawler belt inner side, although this kind of mode reduced the phenomenon that collects careless, but also bring other problem, because moment is smaller, lower cutter less stable, often cause " card machine " phenomenon, after card machine due to the restriction in small harvester space, bring great inconvenience to maintenance.
Utility model content
The utility model, according to the deficiencies in the prior art, provides cutter knife mechanism under a kind of small-sized rice/wheat combine, and the support arm of this mechanism is arranged on the outside of crawler belt, by improving its conversion seat structure, both reduce the careless phenomenon of collection, do not lost again lower cutter strength of stability, be also convenient to Maintenance and Repair simultaneously.
The purpose of this utility model is achieved through the following technical solutions:
Cutter knife mechanism under small-sized paddy combine, mainly comprise left support arm (1), conversion seat (3), moving cutter (5), determine cutter (6) and right support arm (8), described left support arm (1) and right support arm (8) with determine cutter (6) and be designed to one, its corner is provided with erecting bed (4) and reinforcement (7), on described moving cutter (5), be designed with moving knife handle (50), moving cutter (5) is designed to one with moving knife handle (50), it is characterized in that: described conversion seat (3) and erecting bed (4) are arranged on to be determined between cutter top and bottom (60).
Further, described to determine cutter top and bottom (60) be a cambered surface, and top and bottom are symmetrical structure.
Further, it is upper that described conversion seat (3) is arranged on erecting bed (4) by bearing pin, and conversion seat (3) one end is connected with action bars (2), and the other end is connected with the moving knife handle (50) on moving cutter (5).
Further, described action bars (2) and conversion seat (3), conversion seat (3) is connected by bearing pin with moving knife handle (50).
The utility model operating mechanism is arranged between the top and bottom of determining cutter, has reduced the careless phenomenon of collection, and left and right support arm is arranged on the two ends of determining cutter, the outside of crawler belt, intensity is high, for the structure inside support arm is arranged on crawler belt, is more convenient for operating personnel's maintenance.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
The title of parts shown in figure and mark: 1-left support arm, 2-control stick, 3-conversion seat, 4-erecting bed, 5-moving cutter, 50-moving knife handle, 6-determine cutter, 60-determine cutter top and bottom, 7-reinforcement, 8-right support arm.
Embodiment
As shown in Figure 1, cutter knife mechanism under small-sized paddy combine, mainly comprise left support arm (1), conversion seat (3), moving cutter (5), determine cutter (6) and right support arm (8), described left support arm (1) and right support arm (8) with determine cutter (6) and be designed to one, its corner is provided with erecting bed (4) and reinforcement (7), on described moving cutter (5), be designed with moving knife handle (50), moving cutter (5) is designed to one with moving knife handle (50), it is characterized in that: described conversion seat (3) and erecting bed (4) are arranged on to be determined between cutter top and bottom (60).
It is upper that described conversion seat (3) is arranged on erecting bed (4) by bearing pin, and conversion seat (3) one end is connected with action bars (2), and the other end is connected with the moving knife handle (50) on moving cutter (5).
When work, driving mechanism drives action bars (2) to move back and forth, action bars drives conversion seat (3) around bearing pin reciprocally swinging, because conversion seat (3) is connected with moving knife handle (50), thereby order about moving cutter and do left and right reciprocating motion, the standing grain stubble cutting off is through determining cutter upper surface, and lodging, under the crawler belt of left and right, is taken away smoothly.
Claims (4)
1. cutter knife mechanism under small-sized paddy combine, mainly comprise left support arm (1), conversion seat (3), moving cutter (5), determine cutter (6) and right support arm (8), described left support arm (1) and right support arm (8) with determine cutter (6) and be designed to one, its corner is provided with erecting bed (4) and reinforcement (7), on described moving cutter (5), be designed with moving knife handle (50), moving cutter (5) is designed to one with moving knife handle (50), it is characterized in that: described conversion seat (3) and erecting bed (4) are arranged on to be determined between cutter top and bottom (60).
2. cutter knife mechanism under small-sized paddy combine according to claim 1, is characterized in that: described to determine cutter top and bottom (60) be a cambered surface, and top and bottom are symmetrical structure.
3. cutter knife mechanism under small-sized paddy combine according to claim 1, it is characterized in that: described conversion seat (3) is arranged on erecting bed (4) by bearing pin, conversion seat (3) one end is connected with action bars (2), and the other end is connected with the moving knife handle (50) on moving cutter (5).
4. cutter knife mechanism under small-sized paddy combine according to claim 3, is characterized in that: described action bars (2) and conversion seat (3), conversion seat (3) is connected by bearing pin with moving knife handle (50).
