JPS5926831Y2 - Automatic grain culm feeding device in threshing machine - Google Patents

Description

[Detailed explanation of the idea] The present invention relates to an automatic culm feeding device for a threshing machine.

In other words, when the shell culms are placed on a rack during threshing, the shell culms are automatically fed to the threshing machine at intervals, which saves labor by eliminating the need for a feeding worker. To provide a method that enables safe work, allows threshing to be carried out while maintaining threshing sortability easily and reliably, and can be carried out suitably.

Next, the embodiment shown in the drawings will be described.

A indicates a threshing machine, which is a mobile threshing machine with crawler 4.
A threshing machine A is mounted on a machine base 5 supported by , 4, and a control section 6, an engine E, and a paddy receiving section T are installed at the rear part.

Reference numeral B is a foot chain with clamping rods 3 disposed oppositely below it, and a plurality of adjacent chain pins 8 constituting a part of the foot chain B have rolls with a large diameter in the center, leaving both ends intact. An actuating member 9 formed in the upper part is provided, the actuating member 9 extending between the sprockets 10, 10' and being able to rotate, and the upper rail 11
The actuating member 9 is configured to slide on the upper surface of the lever, and the majority of chain pins 8 that are buttoned on the part of the foot chain B where the small actuating member 9 is not provided are configured to slide over the IT trail 1.

Starting end 1 of foot chain B from the drive shaft 12Vc placed on the inlet side of threshing machine A! The sprockets 10 and 10' for driving the IK i-carrying machine are driven, and in a case 15 installed on the entrance side of the threshing machine A, power is transmitted from the shaft of the handling cylinder 13 to the drive shaft 12 via the worm wheel 14. Provided so that

1 is a stand, with the bending part 16 side on the top and the other end 1
The entire structure is tilted with the 7 side at the bottom, and is supported by a stay 18 extending from the side of the threshing machine A. On the other end 17 side of the gantry 1, an inclined presser guide plate 19 is supported by a spring 21 by a support rod 20. Install it by interposing it.

3 between the other end 11 of the gantry 1 and the supply port side of the thresher A
The book carriers 2 are arranged side by side, and each carrier 2 has a surrounding r protrusion 2.
Drive wheel 23 on the side of the thresher A
is configured to be driven by a rotating shaft 24.

On the end side of the drive shaft 12 in the case 15 r, a transmission shaft 25 is aligned and independently installed, and the transmission shaft 2
5VI-Spline fitted clutch body 26 has spring 2γ
The clutch body 26 is provided so that the pawl 28 can be engaged with the worm wheel 14 by pressure, and the clutch body 26 is configured so that power can be transmitted from the transmission shaft 25 to the rotation shaft 24 by the transmission body 29.
is interposed during transmission from the drive shaft 12 to the carrier 2.

C indicates the entire interlocking device, and this device C is connected to the rail 1
A contact plate 30 is provided above 1, and the corresponding punched plate 30, which is pressed by a spring 31, is connected to the chain pin 8 and the operating member 9.
One end of a bell crank type interlocking body 34 which is provided so as to abut from above and is pivoted 33 on the upper metal 32 is connected to the abutting plate 30 by a connecting rod 35 to form a foot chain B.
When the actuating member 9 is in contact with the abutting plate 30 due to the rotation of The shifter 36 that engages with the clutch body 26 and the other end of the interlocking body 34 are interlocked and interlocked by a wire 31, and the abutment plate is moved against the spring 31. When 30 rises.

When the wire 37 no longer performs the secondary operation, the clutch body 26 performs pawl engagement 28 due to the pressure of the spring 27, and each conveyor body 2
is configured so that it is driven.

Although the mobile threshing machine can be moved by the crawlers 4, 4, it must be stopped during threshing.

During threshing, when a large number of rice bundles are placed on the pedestal 1 as shown by arrow A, the pedestal 1 is tilted, so they will slide down to the lower side of the slope. From there, the VC flows one bundle at a time as shown by the arrows, and reaches the upper part of the starting end of each conveyor 2.

When the chain pin 8 of the rotating foot chain B is sliding above the rail 11 as shown in FIG.
The punching plate 30 that comes into contact with the chain pin 8 is lowered, and the wire 37 is pulled as shown in FIG. 8, operating the shifter 36 and the spring 2
7, the clutch body 26 is operated to disengage the clutch so as not to be engaged with the pawl, and each conveying body 2 is brought to a stopped state, and the supply of rice bundles is stopped.

A portion of the foot chain B that continues to rotate, that is, a portion of the plurality of chain chains 8 having the operating members 9 is connected to the rail 11.
Since the r/c does not slide on the rail 11, the contact plate 30
When the actuating member 9 is below the r/
c The abutment plate 30 is pushed up, and while this state continues, the clutch is engaged as shown in Fig. 6, each conveyor 2 rotates, and the rice bundles are transferred to the foot chain B and the supply port. It is transported to the side and supplied.

In other words, rice bundles are intermittently supplied at regular intervals.

Note that the interlocking device C can also be configured to interlock the focus of a part of the clamping rod 3.

In this way, the present invention has a conveyor that is installed in front of the supply port of the threshing machine A, or between the mount 1 and the supply port side, and is driven by the drive shaft that rotates the foot chain to convey and supply the husk. A clutch body is interposed during transmission of power from the drive shaft to the transport body, and an actuating member is provided in a part of the foot chain to prevent the actuating member from coming into contact with the foot chain due to the rotation of the foot chain. Since the interlocking device that is activated due to contact is interlocked with the clutch body to drive the transport body intermittently, the culm can be automatically moved at intervals by simply placing the culm on the pedestal 1. This enables labor-saving work by eliminating the need for a supply worker, and enables safe work without having to manually feed the feed chain as in the past.
In addition, since the husk is fed at intervals, threshing and sorting can be performed smoothly and reliably. Moreover, the operating member installed in a part of the foot chain regularly operates the interlocking device as the foot chain rotates. Since the conveying body is driven intermittently through the clutch body, the husks are always fed at regular intervals, and the above-mentioned threshing and sorting can be carried out easily and reliably in seven stages.
