Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gripping rail for gripping and transporting a grain culm together with the feed chain in opposition to a feed chain. A threshing device, which is provided in a handling chamber so as to be movable up and down as much as possible, and which is provided with a dust sending valve for transferring a thresh-processed material backward with the rotation of the handling cylinder, so that an angle formed with the rotation direction of the handling cylinder can be changed and adjusted. About. 2. Description of the Related Art Conventionally, a dust feed valve is provided on an inner wall of a handling room so as to be adjustable in angle, and the threshing product handled by a handling cylinder by manual angle adjustment of the dust sending valve is transported backward. In some cases, the condition, that is, the transfer distance of the handling cylinder to the rear per unit rotation can be changed. [0003] With this configuration, when the amount of cereal culm per unit time sent to the handling room is small, the angle of the dust valve is reduced to reduce the rearward component force, and the processed material in the handling room is reduced. In order to prevent the load torque of the handling cylinder from being too low by staying in the handling room moderately, when the grain stalk amount per unit time is large, increase the angle of the dust valve to reduce the component force for transporting backward. Enlarging the conveying capacity to prevent clogging of the processed material in the handling room, and to prevent the load torque of the handling cylinder from becoming too high, enabling good threshing according to the supply amount . [0004] However, according to the above-mentioned conventional structure, the manual operation of the dust-feeding valve is troublesome. JP 6-2924
As disclosed in Japanese Patent Publication No. 46, there has been proposed a configuration in which the angle operation member of the dust valve is automatically operated by a control unit and an electric motor controlled by the control unit.
In this configuration, the control means and the electric motor are expensive and the production cost is high. [0005] An object of the present invention is to provide a threshing apparatus which can be manufactured at low cost without troublesome operations for adjusting the angle of a dust valve. [Means for Solving the Problems] [Structure] The characteristic structure of the present invention is that in the threshing apparatus described at the beginning, the holding rail is mechanically linked with an angle operating member of the dust valve. Thus, the configuration is such that the angle of the dust valve increases as the holding rail moves backward. According to the above construction, the holding rail and the angle operating member of the dust valve are mechanically moved so that the angle of the dust valve increases as the holding rail moves backward. Since they are linked together, there is no need for the operator to operate the dust feed valve, and it can be manufactured at a lower cost than when operated by an electric motor or the like. [Effect] Accordingly, it is possible to provide a threshing apparatus in which the operation of adjusting the angle of the dust valve does not require much trouble and the production cost can be reduced. Embodiments of the present invention will be described below with reference to the drawings. As shown in FIG. 3, a threshing apparatus includes a threshing unit A, a sorting unit B, and a collecting unit C. The threshing unit A has a handling cylinder 2 mounted in a handling room 1 and a receiving net 3 extending along the lower side of the handling cylinder 2. Is wrapped and fed by a feed chain 4 and a holding rail 7 opposed thereto from above. Grain stalks conveyed by the handling cylinder 2 are handled and processed, and the processed product is leaked onto the sorting section B. It is configured to supply. As shown in FIG. 1 and FIG.
Is a vertical rod 16 connected to a plurality of rail members 11 by pins 15 so that the rail members 11 can be freely bent up and down.
Is fixed to the upper case 26 by the rail support member 17.
Slidably up and down, and each vertical rod 16
A spring 18 for downwardly urging each rail member 11 is provided so as to be able to cope with a change in the amount of the transported grain. As shown in FIG. 1, FIG. 2, and FIG. 3, a dust feed valve 20 for transferring the threshing material backward with the rotation of the handling drum 2
Is provided on the lower surface 8a of the top plate 8 of the handling chamber 1 so that the angle θ formed with the rotation direction of the handling cylinder 2 can be changed and adjusted. The dust valve 20 includes a fixed dust valve 20B located on the inlet side and the outlet side of the handling chamber, and a number of movable dust valves 20A arranged between the fixed dust valves 20B. The movable threshing valve 20A is configured to vary the angle θ so as to transfer and guide the threshing processed material rearward. More specifically, one end of the connecting upper side formed at the longitudinally intermediate portion of each movable dust valve 20A is connected to the top plate 8.
And a first connecting plate 21 extending between the fixed dust feed valves 20B.
And the other end of the upper side for connection of each movable dust valve 20A is connected to the second connecting plate 22 (along the first connecting plate 21). Each movable dust valve 20 </ b> A is configured to be integrally movable in a parallel state by pivotally connecting to the angle operating member) and moving the second connecting plate 22 in the longitudinal direction. The holding rail 7 and the second connecting plate 2
2 is mechanically linked via an operation wire 23, and when the holding rail 7 rises, the angle θ of the dust feed valve 20 increases accordingly, and when it lowers, the angle θ decreases accordingly. It is configured to be. That is, the second connecting plate 2
2 is urged by a spring 25 in a direction in which the angle θ becomes smaller, and one end of the operation wire 23 is connected to the rear end of the second connecting plate 22.
The other end of the operation wire 23 is connected to the other end of a swinging member 24 in the shape of a “<” that is pushed and pulled up and down by the upper end and swings around the horizontal axis P in a side view. is there. The sorting section B comprises an oscillating sorting section 5 and a Karamin 6 for sending a sorting wind to the oscillating sorting section 5. The collecting section C includes a first article collecting section 13 and a second article collecting section. Consists of fourteen.
Reference numeral 12 denotes a dust discharge fan for discharging straw waste to the outside of the machine together with the sorting wind. [Another Embodiment] The present invention is also applicable to a case where the holding rail 7 is opposed to the feed chain 4 from below. In the claims, reference numerals are provided for convenience of comparison with the drawings, but the present invention is not limited to the configuration shown in the attached drawings.
