Description

[Detailed Description of the Invention] The present invention relates to a scattered grain collection device for collecting scattered grains that are scattered outside the machine together with dust from a dust outlet of a wind sorting section in a pulse threshing machine.

More specifically, as shown in FIG.
Pulses containing crushed pieces of stem culms and capsules leaking through the receiving net 11 are sorted in the wind sorting section 2 provided at the lower part of the body a, and crushed pieces of stem culms and capsules are sorted out. Dust such as shellfish is blown out of the machine from the dust exhaust port 21 provided at the front of the machine body a (on the right side in the figure) by the sorting wind blown from the Karachi blower 20 of the wind sorting section 2, and the grains are sorted. The conveyor 22 (or grain flow board) separates good grains and waste grains, and the good grains are taken out first to the receiving trough 23, and the waste grains carried to the terminal end of the sorting conveyor 22 in the transport direction are removed from the dust outlet 21. The waste is discharged from the terminal end of the sorting conveyor 22 facing the lower layer position or outside the machine body a, and is collected into a No. 2 collection receiver 3 installed or installed outside and below the dust exhaust port 21. This is a device for a certain form of pulse threshing machine A, and is a device for collecting scattered grains that are scattered outside the machine together with dust from the dust outlet 21 of the pulse threshing machine A of such a form. Concerning improvements to collection devices.

The scattered grain collection device in the above-mentioned pulse threshing machine is
In the past, the No. 2 collection receiver 3 installed or installed below the outside of the dust exhaust port 21 had an opening 30 on the top side facing outward of the machine a (as shown in Fig. 1). The waste grains (No. 2) falling from the terminal end 22a of the sorting conveyor 22 as shown by the chain arrow A in FIG. It is configured to receive the peas mixed in the waste and released as indicated by the chain arrow B in FIG. 1.

However, with this conventional means, if the pods are separated from the husks well and the threshed beans are easily dispersed due to conditions such as the dry state of the grain culm of the pulses to be threshed, the dust is scattered from the dust exhaust port 21. The particles to be ejected are discharged outside the second collection receiver 3, increasing the number of particles lost by scattering, and the particles fly out of the upper layer of the dust outlet 21 together with this waste. Since the falling beans are collected together with the waste particles in the No. 2 collection receiver 3, when there are many scattered beans,
There is a problem in that the beans must be re-sorted to separate them from waste grains.

The present invention has been made in order to solve these problems, and makes it possible to effectively collect the beans that are scattered widely from the dust exhaust port 21 into the second collection receiver 3. The object of the present invention is to propose a new means for collecting the beans separately from the waste particles collected in the receiver 3 when the amount of the beans is large.

And for this purpose, in this invention,
Outside the dust exhaust port of the above-mentioned pulse threshing machine, above the No. 2 collection receiver installed outside and below the dust exhaust port, there is a container larger outward than the receiver. An overhanging opening frame is installed, and a hanging curtain is attached to the hanging frame so as to surround the space below the opening frame at least in front of the overhanging direction and on both left and right sides.
