Description

TECHNICAL FIELD

[0001] The application belongs to the field of agricultural and pastoral machinery application, and particularly relates to a floating profiling mechanism of a main-passive combined type silage harvester horizontal roller type feeding device feeding upper roller. BACKGROUND

[0002] The silage harvester requires that the feeding device has good adaptability to the fluctuation of the feeding amount, and there is always sufficient pre-tightening pressure on the crop flow as the feeding amount increases or decreases, so as to ensure that the crop flow will not be too fluffy to cause the moving knife to cut the straw or cause the grass to grow.

[0003] The pre-tightening of the feeding device on the crop flow directly or indirectly affects the subsequent chopping, and therefore the effective pre-tightening action needs to be provided to the crop flow.

[0004] The feeding upper roller of the traditional horizontal roller type feeding device mainly relies on the symmetrical spring pressing mechanism to passively float up and down with the fluctuation of the feeding amount, and cannot provide the best pre-tightening pressure according to the moisture content of the crops and other factors. When the planting density is uneven, the driving speed is unstable, or the ground is uneven, the feeding amount will suddenly increase to cause the feeding inlet to be blocked, or the feeding amount will be insufficient to cause the crops to be not pressed, or the transverse feeding will be uneven to cause the pre-tightening to be unbalanced, and the feeding device cannot actively provide the pre-tightening pressure to the crop flow.

[0005] In view of the above problems, a main-passive combined type profiling mechanism suitable for the floating of the feeding upper roller of the horizontal roller type feeding device of the silage harvester is developed, which can not only realize the passive profiling of the feeding upper roller with the fluctuation of the feeding amount, but also actively control the floating of the feeding upper roller to the required pre-tightening force. When the feeding is uneven, the left and right profiling mechanisms can be adjusted respectively to achieve the transverse pre-tightening balance, so as to effectively pre-tighten the crop flow and improve the chopping quality of the silage harvester. SUMMARY

[0006] The application can not only realize the passive profiling of the feeding upper roller with the fluctuation of the feeding amount, but also actively control the floating of the feeding upper roller to the required pre-tightening force. When the feeding is uneven, the left and right profiling mechanisms can be adjusted respectively to achieve the transverse pre-tightening balance, so as to effectively pre-tighten the crop flow and improve the chopping quality of the silage harvester.

[0007] In order to achieve the above purpose, the application adopts the following technical scheme:

[0008] A main-passive combined type silage harvester horizontal roller type feeding device feeding upper roller floating profiling mechanism is symmetrically arranged on both sides of the feeding device, and mainly comprises an active part, a passive part, an active connecting rod and a passive connecting rod. The active part comprises an active spring and a hydraulic oil cylinder, and the passive part comprises a passive spring and a connecting pin.

[0009] The hydraulic cylinder barrel is hinged to the fixed seat, and the hydraulic cylinder piston rod is hinged to one end of the driving spring; the other end of the driving spring is hinged to the upper end of the driving connecting rod; the driving connecting rod is matched with the fixed shaft through the bearing; the lower end of the driving connecting rod is matched with the rear upper feeding roller shaft through the shaft sleeve interference; the upper end of the passive spring is hinged to the upper end of the passive connecting rod, and the lower end of the passive spring is hinged to the connecting pin; the connecting pin is fixed on the rack through the bolt; the passive connecting rod is connected with the front upper feeding roller shaft through the bearing; the lower end of the passive connecting rod is matched with the rear upper feeding roller shaft through the shaft sleeve interference; the front upper feeding roller and the rear upper feeding roller are fixed on the floating side plate through the bearing, and the front upper feeding roller and the rear upper feeding roller are linked; the fixed seat and the fixed shaft are welded on the feeding device side plate.

[0010] When the feeding upper roller is passively floated, the hydraulic cylinder is not actuated, the front upper feeding roller and the rear upper feeding roller realize the profiling of the feeding amount fluctuation through the passive spring and the passive connecting rod, the driving spring and the driving connecting rod are passively linked, at this time, the front upper feeding roller is the driving roller, and the rear upper feeding roller is the passive roller.

[0011] When the feeding upper roller is actively floated, the hydraulic cylinder is actuated, the driving spring is extended and retracted, the driving connecting rod drives the rear upper feeding roller to float, the passive connecting rod drives the front upper feeding roller to float, and the passive spring is passively extended and retracted.

[0012] When the feeding upper roller is actively floated, the rear upper feeding roller is the driving roller, and the front upper feeding roller is the passive roller.

[0013] The left and right hydraulic cylinders can be synchronously retracted to adapt to the uniform feeding of the crop flow.

[0014] The left and right hydraulic cylinders can be differentially retracted to adapt to the uneven feeding of the crop flow.

[0015] The present application has the following beneficial effects:

[0016] Through the above technical scheme, the present application is suitable for the horizontal roller type feeding device of the silage corn harvester, can realize the passive profiling of the feeding upper roller according to the feeding amount fluctuation through the active and passive combined floating profiling mechanism, or drive the feeding upper roller to achieve the best pre-tightening pressure through the hydraulic cylinder active control profiling mechanism, and can cope with the uneven transverse feeding of the crop flow by respectively adjusting the left and right hydraulic cylinder piston rod strokes, improve the effective pre-tightening control of the feeding device on the crop flow, improve the chopping quality of the silage harvester, and with the continuous improvement of the quality requirements of the mechanical silage harvesting, the mechanism has good popularization and application value in the domestic silage harvester field.

[0028] The present application will be further explained in conjunction with the accompanying drawings and specific embodiments:

[0029] A master-slave combined silage harvester horizontal roller type feeding device feeding upper roller floating profiling mechanism, symmetrically arranged on both sides of the feeding device, mainly includes an active part, a passive part, an active link (12), a passive link (10); the active part includes an active spring (1), a hydraulic cylinder (2); the passive part includes a passive spring (6), a connection pin (8); the active spring (1), the hydraulic cylinder (2), the active link (12) constitute the active part; the passive spring (6), the passive link (10) constitute the passive part; the cylinder barrel of the hydraulic cylinder (2) is hinged with the fixed seat (3), and the piston rod of the hydraulic cylinder (2) is hung with one end of the active spring (1), such as Figure 5 ​The other end of the active spring (1) is hinged to the upper end of the active connecting rod (12), the active connecting rod (12) is matched with the fixed shaft (13) through a bearing, the lower end of the active connecting rod (12) is in interference fit with the rear upper feeding roller shaft (11) through a shaft sleeve, the upper end of the passive spring (6) is hinged to the upper end of the passive connecting rod (10), the lower end of the passive spring (6) is hung to the connecting pin (8), and the connecting pin (8) is fixed on the rack through a bolt Figure 6 The passive connecting rod (10) is connected with the front upper feeding roller shaft (9) through a bearing, and the lower end of the passive connecting rod (10) is in interference fit with the rear upper feeding roller shaft (11) through a shaft sleeve, the front upper feeding roller (5) and the rear upper feeding roller (19) are fixed on the floating side plate (14) through a bearing, and the front upper feeding roller (5) and the rear upper feeding roller (19) are linked; the fixed seat (3) and the fixed shaft (13) are welded on the feeding device side plate (4).

[0030] When the passive floating is realized, the hydraulic cylinder (2) does not act, the front upper feeding roller (5) and the rear upper feeding roller (19) realize the profiling of the feeding fluctuation through the passive spring (6) and the passive connecting rod (10), and the active spring (1) and the active connecting rod (12) are passively linked; at this time, the front upper feeding roller is the active roller, and the rear upper feeding roller is the passive roller.

[0031] When the active floating is realized, the hydraulic cylinder (2) acts, drives the active spring (1) to stretch and retract, drives the active connecting rod (12) and the passive connecting rod (10) to drive the front upper feeding roller (5) and the rear upper feeding roller (19) to float, and the passive spring (6) is passively stretched and retracted; the left and right hydraulic cylinders (2) of the feeding device can be synchronously stretched and retracted to adapt to the uniform crop flow; the left and right hydraulic cylinders (2) of the feeding device can be differentially stretched and retracted to adapt to the uneven crop flow.

[0032] Working principle: crops enter the feeding device after being cut by the cutting table, and the active and passive combined profiling mechanism is symmetrically installed on the two sides of the feeding device, as shown in Figure 1 The passive state, the hydraulic cylinder (2) does not act; the active state, the hydraulic cylinder (2) acts according to the control requirement.

[0033] In the passive state, when the feeding amount increases, the front upper feeding roller (5) floats up, drives the passive spring (6) to elongate, and under the action of the passive connecting rod (10), the rear upper feeding roller (19) is linked and floats up, the active connecting rod (12) rotates counterclockwise, and the active spring (1) is stretched; on the contrary, when the feeding amount is small, the pre-tightening pressure is provided by the self-gravity of the front upper feeding roller (5) and the rear upper feeding roller (19), and the profiling of the feeding roller to the feeding fluctuation in the passive state is completed.

[0034] In the active state, when the feed amount increases and is fed evenly, the hydraulic cylinders (2) on both sides are driven by the controller, and the piston rods extend and compress the active spring (1) at the same time, which drives the active connecting rod (12) to rotate counterclockwise around the fixed shaft (13), thereby driving the rear upper feed roller (19) to float up. The front upper feed roller (5) floats up in conjunction with the floating side plate (14) and the passive connecting rod (10) under the action of the passive spring (6), and the passive spring (6) is stretched accordingly. The reverse is also true, thus completing the active pre-tensioning of the upper feed roller for the fluctuation of the even feed amount in the active state.

[0035] In active mode, when the lateral feeding is uneven, such as Figure 3 As shown, the controller drives the hydraulic cylinders (2) on both sides to supply oil. The piston rod of the hydraulic cylinder (2) on the side with a larger feed amount extends and retracts more than the piston rod on the side with a smaller feed amount. Other structures are linked accordingly to achieve active balancing and pre-tightening of the upper feed roller for non-uniform feed amount fluctuations in active state.

[0036] The structure and working principle of the present invention have been described above with specific embodiments. The present invention is not limited to the above embodiments. Based on the above description, any modifications, equivalent substitutions and improvements made on the basis of the present invention and its principles should be included within the protection scope of the present invention.
