JPS5811815B2 - Grain bagging equipment in combine harvester - Google Patents

Description

[Detailed description of the invention] While the combine harvester is running, the machine body shakes violently in the front and back directions due to unevenness in the field, not only making it impossible to align the stubble evenly, but also having to change the direction of the machine body at the headland. Therefore, it is necessary to shorten the length of the aircraft in the longitudinal direction to make it easier to change direction.

The present invention aims to meet the above-mentioned needs.

When blood is removed in the embodiment of the present invention shown in the drawings, reference numeral 1 denotes a grain tank mounted on the machine body, into which selected grains discharged from a threshing device are fed via a grain lifting machine 2.

Reference numeral 3 denotes an inlet into the tank, which extends above a central discharge tube 5, which will be described later.

Three discharge tubes 4, 5, and 6 degrees are provided at the bottom of the tank 1,
One partition wall A in the tank provided between the central discharge pipe 5 and the adjacent discharge pipes 4 and 6 in front and back thereof is low and the other partition wall B
forms high.

Reference numeral 1 denotes a grain bath outlet bored in the side wall of the tank 1 above the discharge tube 6, which communicates with the outlet tube 8, and the lower end of the outlet tube is connected to the outlet tube 6.
Look above the bottom edge of.

Reference numeral 9 denotes a swing piece supported on the outflow tube 8, one end of which extends into the outflow tube and the other end connected to a switch S of a switch S provided outside the outflow tube.

Switch S then opens and closes the lamp and buzzer alarm circuit.

Reference numeral 10 denotes an opening/closing plate provided for each discharge tube 4, 5, and 6, which is pulled by a spring 11 to open each discharge tube at all times.

Each discharge tube 4, 5, 6 is inserted into the bag opening of the bag F.

A pair of support rods 12 for the bags F are attached to the left and right sides of each of the discharge tubes 4, 5, and 6, which are parallel to the direction in which the machine moves, so that the mouths of each bag are perpendicular to the direction in which the machine moves.

In the present invention, the grains introduced into the tank 1 through the input port 3 first pass through the partition wall A as shown in FIG.

The grains are discharged from the discharge pipe 5 in the center between B to the bag F, and when this is full, the grains rise in the tank as shown by the two-dot chain line, and then the grains that have risen even more are discharged over the low partition wall A. It is discharged from the tube 4 into a bag connected to it.

When it is full, it is discharged from the discharge tube 6 into the bag F over the raised bulkhead B as shown by the dashed line.

When the bag connected to the discharge tube 6 becomes full, the grains swell up in the tank as shown by the broken line, and as shown in FIG. Since it is pressed down, the switch S connected to the other end closes the circuit of the alarm device, and the lamp turns on and the buzzer sounds to notify the worker.

Then, the worker closes the opening/closing plate 10 of each discharge pipe 4, 5, and 6 and replaces the bag.

The grains overflowing into the outflow tube 8 fall and are collected on the surface of the grains in the bag connected to the discharge tube 6.

Therefore, in the present invention, support rods 1 for each pair of bags F are provided on the left and right sides of each discharge tube 4, 5.
2 and each bag opening is perpendicular to the direction of movement of the aircraft, so
As shown in the conventional Japanese Utility Model Application Publication No. 50-1462, the length of the machine body in the front and back direction is significantly shortened compared to the case where each bag opening is lined up in a straight line along the direction of movement of the machine body. Make conversion easy.

Moreover, in the present invention, since the input port 3 in the tank opens above the central discharge pipe 5, the grains first enter the bag F through the central discharge pipe 5 and are filled, so that the front-to-back balance of the machine body is maintained. Not only is this good, but the grain is then discharged into the bags F before and after it, and since these bags are perpendicular to the direction of movement of the machine, they are close to each other, and even when each bag is full, the machine does not move. To calm the front and rear movements of the aircraft without destroying the front and rear balance.

However, among the three bags F, if the end bags, for example, the rear bags, are filled with grain, the center bag will be pushed and distorted, and the front bags will be pushed by the distorted center bag. However, in the present invention, the center bag F is first filled with grains, so the bags before and after are stored in the center bag. Even when pushed, the rear bag tilts backwards, and the front bag tilts forward to accommodate enough grains without distortion.

In short, according to the present invention, the length of the machine body in the longitudinal direction is shortened to facilitate direction change of the machine body, and each bag opening is perpendicular to the direction of movement of the machine body, so each bag approaches each other.
Even when these bags are full, there is no risk of losing the front-to-back balance of the aircraft, and since grains are stored starting from the center bag among the three bags, the bags in front and behind can be pushed by the center bag. It has the effect of sufficiently accommodating grains without distortion.
