Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a grain bag unloading device for a combine harvester, and more specifically, the present invention relates to a grain bag unloading device for a combine harvester. The present invention relates to a grain bag take-out device for a combine harvester, which is equipped with a hoist that lifts and moves the grain bags onto the road when the combine approaches the road and turns the grain bags.

As mentioned above, it is easy to equip the combine itself with a hoist that takes out the grain bags, which are supported on the bag holder of the combine and are discharged from the jut of the grain lifting machine, onto the road. It is very convenient to be able to take out the grain bag, but in this case, the ejector of the grain lifting machine gets in the way when lifting the grain bag, and the grain bag must be lifted diagonally upwards. First, at this time, the bottom surface of the grain bag is rubbed on the pedestal, making it difficult to withstand long-term use. In addition, there was a drawback in that an unbalanced load of 1 was applied to the seven-way hoist for hoisting the grain bags, making it necessary to make the hoist itself large and robust.The present invention aims to eliminate the above-mentioned drawbacks. □ That is, the present invention has taken the following technical measures.

The grain bag removal device of the combine is configured so as to be movable so as not to get in the way when the grain bag θ is lifted in (b), and has the following technical effects.

(1) The grain bag is lifted by a hoist attached to the combine harvester and can be easily taken out on the road or onto the carrier platform. It can be lifted straight up without straining.

(2) The durability of the grain bag can be improved because the grain bag is unnecessarily clean on the bag holder when it is lifted. (3) 9 There is little need to strengthen the structure of the hoist itself. 9. The combine harvester itself can be made lighter.

One embodiment of this invention will be described in detail based on the drawings (1

It is equipped with [6] so that it can be self-propelled. Reference numeral (4) is a control frame, which is installed upright on the vehicle body (1) l in front of the prime mover (3), and various force-operated controls and instruments are attached to this frame. (5) is a cockpit, which is provided above the prime mover (3). (6) is a hot spring.

(7) is a reaping and conveying device, and a reaping device (7) using clippers is used.
a), divider rod (7b), lifting device (7C), conveyance device (
The reaping frame (7) equipped with
This is a well-known system in which a hydraulic lifting device (not shown) is provided at the front part on the left side of 1) so that the row can be lowered.

(8) is a threshing device, which is disposed at the rear of the reaping and conveying device (7), and is mounted on the upper surface of the left side of the traveling vehicle body (1), and its foot chain (8a) is positioned on the left end side. ,
The base of the culm, which is harvested and lifted by the reaping and conveying device (7), is taken over by the foot chain (8a), and the tip side is sent into the handling chamber to be threshed.

(9) is a cutter that is added integrally to the rear side of the threshing device (8), and is installed so that the threshed waste straw is cut into small pieces and scattered over the field.

(11 is like a grain fryer, and is on the right side of the threshing device (8).
A transfer spiral is installed inside the grain lifting cylinder installed in front of the wall, and above this is a transverse feeding cylinder (
11) is provided, and grain discharge ports (lla) and (llb) are provided at the front and rear intermediate and rear end portions of this lateral feeding cylinder (1υ), and grain discharge ports (lla, 03) are provided in this portion at It is provided so that it can rotate around the feeding cylinder (11), and when it is set to rotate downward, the grains are removed from the discharge port (lla), (
llb), flows down through the discharge tubes IJ4 and Qa, and is discharged.

Reference numeral (14) denotes a bag holder, which is constructed by placing a plate on the upper surface of the traveling vehicle body (1) on the right side of the threshing device (8).

The 0-gradation is a grain bag with a closing string (1
5a) and a hanging string (15b) for hoisting the grain bag O (to).
) is not provided.

OQ is a hoist and is attached to a fixed support post O that stands on the right rear side of the bag holder α by inserting an elevating support that can be adjusted up and down and fixed with a bin 08), and this elevating support 0
A freely rotatable rotating tube end is provided, and this [Nl moving tube (4)
An arm Qυ is installed at the upper end of the arm QD, and a reducer and a brake are installed at the top of the base side of this arm QD. After that, a string (c) was wound around the take-up roll (c) fixed to the drive shaft of the motor (2) and the pulley wire, and a hanger 9 was attached to the tip of the string. It is. Furthermore, (c)
, the handle is a reinforcing frame that holds the armshi υ, 0@ is the battery, the handle is the switch, and the handle is connected to the motor (a) by the electric circuit of the 6th Bl.

Next, to explain the function of the upper part, 1st, for reaping and threshing work, 04°0 cypress
ljl! downward as shown by the solid line in the figure! I move the discharge tube Q'4. Insert the lower end of the bag into the opening of the bag of 17 bags of grain, which can be received on the bag holder (141).
It is attached by a closing string (15a) at the top of the flange which is integrally fixed to the lower side of Q3.

In this state, reaping and threshing work is started. Then, the planted husks in the field are harvested by the reaping and conveying device (7) and transported backwards and upwards, the grain base is taken over by the foot chain (8a), and the tip of the grain is sent into the handling room where it is threshed. will be done.

Then, the threshed and sorted grains are lifted up by the grain lifter and sent backwards in a spiral in the cross-feeding cylinder (1), and first through the discharge port (Ila) and through the discharge tube a2. Front grain bag a1
discharged inside. When the front grain bag θ is full, the grains are continuously sent to the rear and discharged into the rear grain bag.

In this way, the harvesting and threshing work continues, but when the combine turns to approach the ridge along the road, the work is temporarily stopped during or immediately after the turn, and the front side filled with grain is removed. Rotate the ejection tube inserted into the bag opening of the grain bag U to remove it, close the bag opening with the string (15a), and then reverse the motor (A) by turning the switch ζ. After unwinding the string (A), hook the hanging tool (A) onto the hanging string (15b).

Next, operate the switch (G) to rotate the motor (A) in the forward direction (7. Lift the grain bag α upward. At this time, there is a discharge tube 0 on the top of the grain bag α). Since the grain bag is not located, it is possible to easily lift the grain bag without the need for troublesome operations such as lifting it from lying down.

Then, in this lifted state, the arm (21) can be rotated toward the road and left on the road.

Note that the rear grain bag is rarely full, but when it is full, it can be taken out using the hoist as described above.

Incidentally, if the road is high, it is sufficient to adjust the height of the lifting support to a high value in advance.

Also, adjust the angle of the arm t21) to the reinforcing frame (
It would be even more convenient to change the mounting position of c) by changing it back and forth using the pin O1).

Next, when restarting the work, it is preferable to rotate the discharge tube a'lJ downward in the same manner as when starting the work, and attach a new grain bag Q9.
