Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a front cover device for a combine harvester.

In other words, in a combine harvester in which a reaping and conveying section is installed from a pulling body at the front of the machine body to the supply port in front of the threshing machine's supply port, the upper part in front of the threshing machine is covered with a parallel double-strength bar to prevent rainfall. At the same time, it prevents rainwater from flowing into the threshing machine from the supply port, and also prevents rainwater from splashing on the reaping conveyance section, allowing for smooth conveyance and threshing of the reaped husks.Moreover, it has a safe structure as a safety cover. In addition, the left cover on the foot chain side can be opened to the right cover side, so that grain culms can be fed by hand, and in this case, the reaping and conveying section is stopped in conjunction with the opening of the left cover to ensure safety. It is an object of the present invention to provide a front cover device for a combine harvester that can be secured.

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

FIG. 1 shows a perspective view of the entire combine harvester, in which a threshing machine 2 is mounted above both crawler-type running bodies 1, 1, and the handling trunk cover 3 of the threshing machine 2 and the cover 5 of the foot chain 4 are the same. The cover 6 of the straw removal section above the sorting section at the rear of the threshing machine 2 is also flush with the handling barrel cover 3, and on the right side of the threshing machine 2, the engine cover 7 and the paddy receiver cover 8 are placed front and back. , a paddy bag mounting stand 10 is attached above the cover 9 at the rear thereof.

In addition, a reaping conveyance section 12 is installed in front of the supply port 11 in the threshing machine 2, and a weeding body 13 and a raising body 14 are installed obliquely at the frontmost part, so that the raising body 14 and the supply port 11 are connected to each other. In between, there is constructed a reaping conveyance section 12 consisting of a cutting blade, a conveying chino, a tip conveying tine, etc., similar to the conventional structure.

A control platform 15 and a seat 16 are installed in the front and rear on the right side of the reaping conveyance section 12, and a reaping latch lever 17 is installed on the control platform 15, and a drive case 18 of the reaping conveyance section 12 is installed.
is provided with a manual pulley 19 that is driven by a belt from the engine, and a tension clutch pulley 20 that tensions or loosens the belt allows the clutch to be turned on or off.
1 so that the tension clutch pulley 20 can be operated.

In addition, A and B are the left cover and the right cover, and the above-mentioned double force bars A and B are located between the front part of the handling trunk cover 3 and the upper frame body 14a of the lifting body 14. The supply plate 22 and the reaping conveyance section 12 are arranged side by side so as to cover the upper part thereof, and a support shaft 23 is attached to the joint part of the double force bars AB arranged in parallel in the front-rear direction of the machine body, and the double force bars A,
Attach the joining side end of B to the support shaft 23 via a hinge, and connect one left cover A to the other right cover B side, and connect the other right cover B to one left side, with the support shaft 23 as the center. The handles 24 and 25 are respectively attached to the opposite side of the support shaft 23 of the double force bars A and B, so that when one left cover A is opened, the handles 24 and 25 are opened so that they can be opened back to back. Grain culms can be put in from the open part and fed to the starting end of the foot chain 4, and when the other right cover B is opened, the reaping conveyance part 12 can be visually observed from the operating side.

The end of a wire 26 is attached to a portion of the left cover A near the support shaft 23 by connecting it to a link 27, and the wire 26 is passed through a guide 28 provided near the link 27.
The end portion of the clutch is connected to the tension clutch pulley 20 side, and when the wire 26 is pulled, the clutch can be released.

Therefore, before and after the threshing machine 2, the raising body 14
From the top of the bar A, B, handling trunk cover 3 cover 5
Then, the cover 6 becomes a substantially horizontal plane and is stretched, so that even if it rains, rainwater will not flow into the threshing machine 2 from above the supply plate 22 due to the double force bars A and B.
In addition, when the operator sitting on the seat 16 wants to check the operating state of the reaping conveyance section 12, he/she should grasp the handle 25 and move the right cover B to the support shaft 23 as shown by arrow A.
You can rotate it around the center and open it for visual inspection, or if you want to feed grain culms manually, hold the handle 24 and rotate the left cover A around the support shaft 23 as shown by the arrow. Then open the opening, insert the grain culm through the opening, and insert the foot chain 4.
can be supplied to

In that case, when the left cover A opens, the wire 2
6 is pulled, the tension clutch pulley 20 is actuated to disengage the clutch, and the reaping conveyance section 12 can be stopped and the reaping can be safely supplied without interruption.

In addition, by stopping the operation and opening the left cover A by grasping the handle 24, you can clean and inspect the culm side conveyance section of the reaping conveyance section 12, and by grasping the handle 25 and opening the right cover B, you can clean and inspect the tip side conveyance section. can be cleaned and inspected.

In this way, the present invention provides a combine harvester in which a reaping and conveying section is installed from the lifting body at the front of the machine body in front of the supply port of the threshing machine to the supply port. A left cover and a right cover are arranged side by side between the upper side of the reaping bar and the right cover to cover the reaping conveyance section, and one of the left covers is placed in parallel with the upper side of the The cover can be opened to the other right cover side, and the grain culm can be supplied to the threshing machine from this opening, and
Since the transmission clutch of the reaping conveyance section is disconnected and activated in conjunction with the opening of the left cover, rainwater can flow into the threshing machine from the supply port and into the reaping conveyance section by installing double force bars in parallel. In addition to preventing the grain from peeling off, the upper part of the reaping and conveying part can be covered to create a safe structure. When the left cover is opened, grain culm is supplied from above from the open part, allowing for manual threshing. It is easy to do this, and when it is opened, the reaping conveyance section is automatically stopped, allowing for safe, cutting-edge work.Also, by stopping the operation and opening the left cover, you can clean the culm side conveyance section of the reaping conveyance section. It has features such as easy inspection.
