Abstract
The utility model discloses a header below a small size rice and wheat harvester, which comprises a secondary cutting apparatus (1), a swing arm assembly (2), a crank arm assembly (3), a hanging rack assembly (4), a chain wheel (6), an installing rack (8) and a power transmission assembly (9), wherein the secondary cutting apparatus (1) is matched with the swing arm assembly (2) which is connected with the crank arm assembly (3); the crank arm assembly (3) is fixed on a chain wheel shaft which is arranged on the hanging rack assembly (4); the hanging rack assembly (4) is fixed on the installing rack (8) which is fixed on the power transmission assembly (9); the chain wheel (6) is matched with the power transmission assembly (9); the secondary cutting apparatus (1) is fixed on the hanging rack assembly (4) through a single arm hanging rod (5). After adopting the structure, the utility model has the advantages of simple structure, good passing ability for straws, and convenient operation and use, etc. Besides, the secondary cutting apparatus is not easy to contact the ground.
Description
Technical field
The utility model relates to the lower cutting table device of a kind of grain header of secondary cut, particularly a kind of small-sized harvester for both rice and wheat.
Background technology
At present, the grain header of secondary cut, particularly power consumption is little, the threshing separating property is good, production efficiency is high and the rice wheat straw direct returning to farmland of secondary cut can be made characteristics such as fertilizer owing to having at the small-sized harvester for both rice and wheat below 1 meter for swath, and welcome at extremely vast plantation family; But the small-sized harvester for both rice and wheat of existing secondary cut also exists following problem, the one, lower cutting table all adopts both arms to articulate bar and fixes, in the use, both arms articulate bar can block the rice wheat straw that lower cutting table is cut off, and accumulate in heapsly, overthrow the straw that does not cut grain ear, grain ear turns forward, upper header is cut less than grain ear, cause the grain ear loss; It is minimum spacing that next is that lower cutting table does not have, and make lower cutting table hit soil often, causes the secondary cut device to damage.
Summary of the invention
In order to overcome the problem of above-mentioned existence, the utility model provide a kind of simple in structure, the straw trafficability characteristic is good, easy for operation and the secondary cut device is difficult for hitting the small-sized harvester for both rice and wheat lower cutting table device on ground.The technical scheme that its technical problem that solves the utility model adopts, comprise secondary cut device, swing arm assembly, connecting lever assembly, hitching frame assembly, sprocket wheel, installing rack, power transmission assembly, the secondary cut device cooperates with the swing arm assembly, the swing arm assembly is connected with the connecting lever assembly, the connecting lever assembly is fixed on the sprocket shaft, sprocket shaft is arranged on the hitching frame assembly, the hitching frame assembly is fixed on the installing rack, installing rack is fixed on the power transmission assembly, sprocket wheel and power transmission assembly coupling, described secondary cut device articulates bar by single armed and is fixed on the hitching frame assembly.
Promptly cede territory for straw is discharged to the right, described single armed articulates the relative secondary cut device of the bar center line s that setovers left and does not promptly cede territory between 50-150mm.Described swing arm assembly and connecting lever assembly are arranged on the left side that single armed articulates bar.
In order to prevent that the secondary cut device from hitting soil, described single armed articulates on the installing rack of bar below and is fixed with limited block, limited block make the secondary cut device overhead height h greater than 170mm.
After adopting said structure, the secondary cut device adopts single armed to articulate bar and is fixed on the hitching frame assembly, and single armed articulates bar and setovers left and promptly do not cede territory, and straw can not be stopped up when cutting; Limited block is set on installing rack, makes the secondary cut device can not hit soil; Have simple in structure, the straw trafficability characteristic is good, easy for operation, the secondary cut device is difficult for hitting advantages such as ground.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 makes the plan structure schematic diagram of novel lower cutting table for this reality.
Embodiment
Illustrated in figures 1 and 2, specific embodiments for the small-sized harvester for both rice and wheat lower cutting table of the utility model device, it comprises secondary cut device 1, swing arm assembly 2, connecting lever assembly 3, hitching frame assembly 4, sprocket wheel 6, installing rack 8, power transmission assembly 9, secondary cut device 1 cooperates with swing arm assembly 2, swing arm assembly 2 is connected with connecting lever assembly 3, connecting lever assembly 3 is fixed on the sprocket shaft, sprocket shaft is arranged on the hitching frame assembly 4, hitching frame assembly 4 is fixed on the installing rack 8, installing rack 8 is fixed on the power transmission assembly 9, sprocket wheel 6 and power transmission assembly 9 couplings, described secondary cut device 1 articulates bar 5 by single armed and is fixed on the hitching frame assembly 4; Described single armed articulates the bar 5 relative secondary cut device center lines s that setovers left, and the span of s is preferably between the 50-150mm, can guarantee so can not stop up when straw separates, and can guarantee that again single armed articulates the bonding strength of bar 5; Described swing arm assembly 2 and connecting lever assembly 3 are arranged on the left side that single armed articulates bar 5; Described single armed articulates on the installing rack 8 of bar 5 belows and is fixed with limited block 7, and limited block 7 makes overhead height h of secondary cut device 1, and overhead height h can guarantee like this that more preferably greater than 170mm secondary cut device 1 can not hit soil.
During the utility model work, power transmission assembly 9 drives sprocket wheel 6 and rotates, sprocket wheel 6 drives 3 rotations of connecting lever assembly by sprocket shaft, connecting lever assembly 3 makes 2 swings of swing arm assembly, swing arm assembly 2 drives the knife section side-to-side movement of secondary cut device 1, and the knife section of secondary cut device 1 and ledger-plate cooperate realizes the cutting straw.
