Abstract
The utility model discloses a combine's straw reducing mechanism, including fixing the shim on direction shell bottom plate, it is equipped with the bar through -hole to overlook projected position corresponding to the shim on the bottom plate, the shim makes progress out from the bar through -hole, and lie in the bar through -hole at the bottom plate lower surface and wherein be equipped with vertical decurrent fixed supporting spring in the edge of one side, be equipped with a round hole on the fixed supporting spring, the one side that lies in the round hole horizontal direction uses the center of round hole to be equipped with round curved hole as the centre of a circle, is equipped with two bolt holes at the shim bottom level, and two bolt holes are corresponding with circle curved hole in the round hole respectively, the shim passes through the bolt fastening on fixed supporting spring, and center that the shim used the round hole is slope rotation around the centre of a circle. Compared with the prior art, the utility model, when reaping the operation, when harvester driving system load is too big, through the inclination of adjustment shim, make it incline to straw discharge direction, reduce harvester driving system's load.
Description
Technical field
The utility model relates to harvesting apparatus, particularly the straw millstone of combine.
Background technology
Along with social development, agricultural mechanization is more and more universal, when the crop harvesting such as wheat, paddy rice, substantially realizes combine operation.In order to improve the availability of wheat rice straw, avoiding the fire hazard because crop straw burning brings, by configuring straw millstone on combine, the stalk exported from combine being pulverized, then shedding in the middle of farmland, realizing straw-returning.Existing straw millstone arranges shredding mechanism in one end of sheller unit, by helical feed, the stalk after threshing is transported to shredding mechanism place, sheds in farmland after being shredded by shredding mechanism.If application number is the Chinese utility model patent of 200920167556.4, disclose one " stalks cutting of combine and scattering mechanism ", comprise rotating shaft, cut grass-removing wheel, ledger-plate, guiding shell, ledger-plate is fixed on the lower shoe of guiding shell, cut grass-removing wheel and be provided with cutterhead, cutterhead is provided with knife section.The passive blade of stalk after threshing and ledger-plate shred, guiding of then being dished out shell.
This technology is extensively used, but in current straw millstone, the dynamical system of knife section is normally in transmission connection with the dynamical system of sheller unit, therefore cutting in Lysimachia sikokiana process, can increase the load of the whole dynamical system of grain header.
Utility model content
In order to overcome above-mentioned defect, the utility model provides a kind of straw millstone of combine, and its ledger-plate cutting grass arranging device can adjust angle of inclination, thus resistance when changing knife section work, the load of adjustment grain header dynamical system.
The utility model is achieved through the following technical solutions:
The straw millstone of combine, comprise the ledger-plate be fixed on guiding shell bottom plate, the position described base plate corresponding to ledger-plate downward projection is provided with strip through-hole, described ledger-plate upwards passes from strip through-hole, fixing supporting spring is straight down provided with at the edge that base plate lower surface is positioned at strip through-hole wherein side, described fixing supporting spring is provided with a circular hole, the side being positioned at circular hole horizontal direction with the center of circular hole for the center of circle is provided with circular arc through hole, two bolts hole are provided with at ledger-plate bottom level, two bolts hole are respectively at circular hole and circular arc through hole correspondence, described ledger-plate is bolted on fixing supporting spring, ledger-plate with the center of circular hole for the center of circle tilts forward and back rotation.
The length of described strip through-hole is greater than the width of ledger-plate.
The beneficial effects of the utility model:
The utility model compared with prior art, when harvesting, time grain header dynamical system load is excessive, by adjusting the inclination angle of ledger-plate, making it tilt to stalk discharge direction, reducing the load of grain header dynamical system.Time ledger-plate is vertical, highly the highest, stop that the ability of stalk is the strongest, cutting required drive is larger, and therefore grain header dynamical system load is the highest.And ledger-plate inclination angle is forward larger, stop that the ability of stalk is more weak, so, the load of grain header dynamical system can be reduced.

Fig. 2 is A direction view in Fig. 1.
Fig. 3 is the utility model ledger-plate structural representation.
Fig. 4 is the structural representation that the utility model ledger-plate is arranged on base plate.
Embodiment
Composition graphs 1 to Fig. 3, the utility model comprises the ledger-plate 2 be fixed on guiding shell bottom plate 1, the position described base plate 1 corresponding to ledger-plate 2 downward projection is provided with strip through-hole 3, described ledger-plate 2 upwards passes from strip through-hole 3, fixing supporting spring 4 is straight down provided with at the edge that base plate 1 lower surface is positioned at strip through-hole 3 wherein side, described fixing supporting spring 4 is provided with a circular hole 5, the side being positioned at circular hole 5 horizontal direction with the center of circular hole 5 for the center of circle is provided with circular arc through hole 6, two bolts hole 7 are provided with at ledger-plate 2 bottom level, two bolts hole 7 are respectively at circular hole 5 and circular arc through hole 6 correspondence.
As shown in Figure 4, ledger-plate 2 is fixed on fixing supporting spring 4 by bolt 8, ledger-plate 2 with the center of circular hole 5 for the center of circle tilts forward and back rotation.
Conveniently ledger-plate 2 rotates, and the length of strip through-hole 3 is greater than the width of ledger-plate 2, and strip through-hole 3 two ends reserve space.
Claims (2)
1. the straw millstone of combine, comprise the ledger-plate be fixed on guiding shell bottom plate, it is characterized in that: the position described base plate corresponding to ledger-plate downward projection is provided with strip through-hole, described ledger-plate upwards passes from strip through-hole, fixing supporting spring is straight down provided with at the edge that base plate lower surface is positioned at strip through-hole wherein side, described fixing supporting spring is provided with a circular hole, the side being positioned at circular hole horizontal direction with the center of circular hole for the center of circle is provided with circular arc through hole, two bolts hole are provided with at ledger-plate bottom level, two bolts hole are respectively at circular hole and circular arc through hole correspondence, described ledger-plate is bolted on fixing supporting spring, ledger-plate with the center of circular hole for the center of circle tilts forward and back rotation.
