Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for attaching a catch screen to a processing barrel chamber provided below the threshing chamber of a pulse threshing machine.

More specifically, as shown in FIG. 1, the pulse threshing machine targeted by the present invention has a threshing chamber 2 in which a handling barrel 20 is horizontally housed in the upper part of a box-shaped machine body 1. The receiving net 2 of the threshing room 2 is installed on the rack.
1, a processing barrel chamber 4 in which the processing barrel 3 is horizontally accommodated.
is installed, and a wind screening section 6 is installed below the receiving net 5 in the processing barrel chamber 4, and the grain culms of pulses are
The grains are fed into the threshing chamber 2 through the supply port 2a and coarsely threshed, the stalks and culms are discharged outside the machine through the discharge culm opening 2b, and the threshed grains are leaked into the processing barrel chamber 4 from the receiving net 21 of the threshing chamber 2. The threshed grains are reprocessed in the processing barrel 3, and are roughly sorted by the receiving net 5 in the processing barrel chamber 4, and the legumes containing crushed pieces of grain culms and capsules are allowed to leak into the wind sorting section 6. , the waste such as stem culms and capsules is discharged outside the machine from the dust outlet 4a of the processing barrel chamber 4 provided in the machine wall 10 on the front side of the machine body 1, and the bean particles leaking from the receiving net 5 are removed. This is a pulse threshing machine that is used so that grains such as grains are subjected to wind selection processing in a wind selection section 6 and then taken out of the machine by a first screw 60.

In the pulse threshing machine of this type, when threshing the beans, if the grain culm of the beans is insufficiently dried and has a high moisture content, the processed material may be deposited in the receiving net 5 of the processing barrel chamber 4. This deposit causes clogging and makes the screening effect of the receiving net 5 insufficient, so it is necessary to clean the receiving net 5 frequently.

By the way, in order to clean the receiving net 5, the receiving net 5 is assembled to the fuselage frame when the aircraft body 1 is assembled, and in order to remove it and pull it out of the aircraft,
Since it is necessary to remove the outer wall of fuselage 1,
There is the trouble of having to insert one's hand into the dust exhaust port 4a of the processing barrel chamber 4 to perform cleaning work.

The purpose of the present invention is to clean the receiving net 5 in the processing barrel chamber 4 by easily taking it out of the machine. It is an object of the present invention to provide a mounting means that can be attached to and detached from the vehicle.

For this purpose, in the present invention, in the above-mentioned pulse threshing machine, it is lowered from the inner surface of the left and right walls of the machine body toward the center of the left and right sides of the machine body so as to form a bulkhead on the lower peripheral side of the processing barrel. A pair of left and right grain plates that are inclined and protrude form joint surfaces along the longitudinal direction of the fuselage on the lower surfaces of their left and right opposite lower edges, and a joint surface is formed between each of the lower edges of the grain plates. The receiving net of the processing barrel, which is formed into a semi-cylindrical shape with its axis along the longitudinal direction, is formed separately from the grain distribution plate and is installed on the front wall of the aircraft. A joint surface is formed on the upper surface side of both left and right edges of the grain board to face the joint surface of each lower end edge of the grain board from below. Rails that run in the front-rear direction are installed on the lower surfaces of the left and right edges, and rails that are installed on the left and right edges of the receiving net are fitted below the lower edges of the left and right grain boards. A matching guide rod is arranged and fixedly supported on the fuselage, and a mounting plate is installed at the front end of the receiving net to be detachably attached to the front of the machine wall on the front side of the fuselage. The present invention proposes a means for configuring an attachment device for a receiving net.
