Description

[Detailed Description of the Invention] The present invention relates to a weed cutting device for a harvester for crops such as rapeseed.

In other words, in a rapeseed or other crop reaper configured to cut the planted crops such as rapeseed with a cutting blade located below the front of the machine and convey it to the rear side, when reaping, the harvested crops are intertwined with the planted crops on the uncut side. Side crops can be cut by the weed cutting blade to ensure good weeding and reaping, and when not working, the grass cutting blade can be covered with a safety cover to keep it in a safe state, making it a safe structure and suitable for implementation. We will provide it to you as soon as possible.

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

Fig. 1 shows a side view of the whole rapeseed crop harvester, which is installed so that it can run by both crawlers 4 at the bottom of the machine body equipped with an engine 2 and a transmission case 3, and the inclination can be changed using the handle 5 at the rear. Both reaping frames 7, 7' are installed at a certain distance from the front part of the frame 6, and slanted grass dividing plates 8, 8' are provided at the front ends of both reaping frames 7, 7'. Each is equipped with
A portal frame 9 is erected above both reaping frames 7, 7', and both reaping frames 7, 7' are connected to each other.
A reciprocating type cutting blade 1 is installed horizontally across the rear part of the blade 7'.

Further, above the cutting blade 1, there are both raking foils 10, 1.
0' and scraping belts 11 and 11' are arranged in parallel, a lower conveying chain 12 is provided extending rearward from above one of the scraping wheels 10', and an upper conveying body 13 is installed above it. , the rear part 12a of the lower conveyance chain 12 and the rear part 13a of the upper conveyance body 13 are extended toward the right, and a storage box 14 is installed on the right side of the machine body so as to face forward and backward.

A vertical weeding blade A is installed on the left side of the portal frame 9 above the rear side of the left weeding plate 8, and the weeding blade A is mounted on a cutting blade stand 15 with a fixed blade 16 and a movable blade 17. The mowing blade A is configured to be installed in a clipper style, and the weed cutting blade A is driven by a bell crank type drive pestle 19 by a back and forth swinging pestle 18 extending from the rear.

A safety cover B is attached to the mowing blade A, and the safety cover B consists of plate covers B1 and B2 on both sides facing forward from both sides of the entire upright mowing blade A, and the rear part of both covers B1 and B2. Support shaft 2 fixed to
0 is installed on the metal 21 of the portal frame 9, and the lower parts of both support shafts 20 are attached to rotary solenoids 22, 22, respectively, and the support shafts 20 are installed by the operation of the rotary solenoids 22, 22.
The covers B1 and B2 are configured to rotate around the center so that they can be opened and closed.

Further, 23 indicates a traveling clutch lever for operating the crawler 4 side, and 24 indicates a reaping clutch lever for operating the reaping side, each of which is equipped to operate the sensors 25 and 25' when both levers are turned on. Set and configure.

FIG. 8 shows an electrical circuit diagram, and the circuit connected to the battery 26 and rotary solenoid 22 includes switches 25a and 25a' which are opened and closed by the sensors 25 and 25'.

9 to 11 show another embodiment, which is constructed substantially the same as the previous embodiment, but with a gate-shaped frame 9.
The safety cover B for the grass cutting blade A installed on the side of the grass cutting blade A is structured to double as a grass cutting board. 28, a grip spring 28' is interposed around the support pin 27, and the tip of the safety cover B is formed long enough to reach the tip of the cutting frame 7 and the upper end of the weeding blade A. An operating lever 31 inserted into a groove 30 in 29 and operated is connected to one end side of the safety cover B by a wire 32.

In addition, P in the figure indicates rapeseed.

In the embodiment shown in FIGS. 1 to 8, when the traveling clutch lever 23 and the reaping clutch lever 24 are turned on as shown in the imaginary lines in FIGS. 6 and 7, as shown in FIG. The rotary solenoid 22 is actuated by the circuit, and both covers B1 and B2 are opened on both sides and rotated backwards.
As shown by the imaginary lines in FIG. 4 and as shown in FIG. 5, the safety cover B is in an open state.

In this state, the machine moves forward, and the left side weeding plate 8 is weeding the rapeseed while receiving the planted rapeseed for reaping between the two weeding plates 8, 8'. The intertwined part between the planted rapeseed and the rapeseed on the reaping side is cut by the splitting blade A, and the rapeseed P, which is directly harvested by the cutting blade 1, is held between the lower conveying chain 12 and the upper conveying body 13 as shown in Fig. 1. The rapeseed P can be harvested by transporting the rapeseed to the rear, and then discharging it into the storage box 14 as shown in FIG. 2 while being laid down while being transported horizontally.

In addition, the reaping clutch lever 24 can be turned off to stop the reaping section, or the traveling clutch lever 24 can be turned off to stop the reaping section.
3 is turned off to stop running, the rotary solenoid 22 turns off both levers B1 and B2.
rotates to form a safety cover that covers the weed cutting blade A as shown in FIGS. 1 to 4.

In other embodiments shown in FIGS. 9 to 11, when the safety cover B is removed from the weeding blade A, it can be used as a weeding board as shown in FIG. At times, by operating the operating lever 31, the weeding blade A can be attached as shown in FIG. 11 to create a safe structure.

As described above, the present invention is a rapeseed or other crop reaper that is configured to harvest crops such as rapeseed with a cutting blade located below the front of the machine and convey it to the rear. A weed cutting blade is vertically installed on the side of the mower for cutting off the crops on the reaped side that are intertwined with the planted crops on the uncut side, and the weed cutting blade can be opened and closed with a safety cover. Since it is installed and configured so that it is covered, during reaping, the safety cover is open and the cutting blade cuts off the crops on the cutting side that are intertwined with the planted crops on the side uncut side, allowing for good weeding and reliable reaping. When not in operation, the mowing blade can be covered with a safety cover to put it in a safe state, and has a feature that it can be suitably implemented as a safe structure.
