Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an improvement of a grain culm feeding device in a pulse threshing machine for threshing pulses such as soybeans.

[Prior Art] A pulse threshing machine supplies grain culms to be threshed (threshed) into a threshing chamber provided in its body, as described in Japanese Patent Application Laid-Open No. 141255/1983 and Japanese Patent Application Laid-open No. 1983-141-
As stated in Publication No. 155920, a supply conveyor consisting of an endless conveyor belt is installed at the supply port of the threshing chamber so as to protrude outside the machine, and grain culms are placed on the conveyor surface of the conveyor belt. By going,
This conveyor belt sequentially transports the grains into the threshing chamber.

[Problem to be solved by the invention] The conventional pulse pulverizer configured in this way has the following problems:
A supply conveyor installed in the machine so as to protrude outside the machine from the supply port of the threshing chamber will carry the beans that have already fallen off the husks of the grain culms into the threshing chamber together with the grain culms. Therefore, the pulses that have already been shredded are unnecessarily subjected to the shredding process in the shredding chamber inside the machine, which causes a problem of increasing the number of damaged grains.

For this reason, if the supply conveyor installed at the supply port of the threshing chamber is mounted on the machine so that it slopes downward from the supply port to the outside of the machine, as described in Japanese Patent Laid-Open No. 57-155920, A problem arises in that the beans that fall off the grain culm during feeding are scattered outside the machine, resulting in lost grains.

In addition, by providing a supply conveyor in this way, the waste culm (second product), which is the threshed grain culm, discharged from the culm opening of the pulse threshing machine, which contains a large number of separated beans, can be removed. When the waste is fed into the machine by a feeding conveyor for reprocessing,
A problem has arisen in which the beans that have fallen off the pods and are mixed in with the waste culm begin to fall toward the outside of the machine, which is the inclined downward side of the supply conveyor, and are scattered outside the machine. It's coming.

In addition, if the supply conveyor is mounted on the machine so that it slopes downward toward the supply port of the threshing chamber,
Not only does the position of the starting end of the supply conveyor in the conveying direction become high, which impairs work efficiency, but also when the grain culm or waste culm is fed to the supply conveyor, the husks of the grain or waste culm are already removed. The flow of separated grains that do not require threshing or reprocessing into the interior of the machine becomes serious, increasing the occurrence of the aforementioned damaged grains.

[Purpose] The present invention was made to solve these problems, and the supply conveyor doubles as a sorting conveyor to effectively separate the legumes falling off from the supplied grain culms as fine grains. Further, it is an object of the present invention to provide a new means that allows the fine particles to be collected from the first port provided in the machine body without causing any damage.

[Means for solving the problem] In the present invention, as a means to achieve this objective, a supply conveyor consisting of an endless conveyor belt is installed outside the supply port of the threshing chamber installed in the machine body. The conveying surface of the conveying belt is tilted at an angle that causes the grains to fall to the downward slope side, and the conveying surface of the conveying belt is tilted upward toward the supply port. A conveyor gutter is installed below the supply conveyor in an attitude of descending and tilting toward the machine body, and a receiving port formed at the inclined rising end of the conveyor gutter is installed at the lower part of the supply conveyor. A swinging sorting shelf is installed in the machine body, the discharge port being disposed below the starting end of the conveyance belt in the conveyance direction, and the discharge port formed on the inclined descending end side of the conveyance gutter being disposed below the threshing chamber. , proposes a grain culm feeding device for a pulse threshing machine which is connected to the starting end side of a lower grain feeding plate.

The receiver y is made to protrude from the rear side of the body a, and cooperates with the rear end portion of the rocker frame 62 to form a receiver y whose upper surface side is open on the rear side of the body a. Then, the above-mentioned conveying gutter 5 is installed in a receiver y installed at the rear end side of the grain feeding plate 6b in the lower layer of this swing sorting shelf 6 so as to protrude toward the rear side of the machine body a.
facing the discharge port 52a at the lower end of the discharge cylinder 52, the beans falling from the rear end of the supply conveyor 3 and the front end of the supply table 4 flow into this receiver y via the conveyance gutter 5, The grains are collected from this receiver y to the first receiving gutter 72 of the wind sorting section 7 via the grain feeding plate 6b.

In the illustrated embodiment, reference numeral 13 indicates the upper shedding roll 11 and the lower shedding roll 1.
It is a transmission mechanism that conducts rotation in the opposite direction to 1.

[Function] The embodiment device configured as described above functions as follows.

When grain culms of beans are supplied into the threshing chamber 1 from the supply port 2 of the pulse threshing machine A to perform threshing processing work, When reprocessing is performed by feeding grain grains (grain grains) into the grain threshing chamber 1 from the supply port 2 of the pulse threshing machine A again, the grain culms or waste grains are
Grain culms or waste culms are placed on the top of the bed plate 40 and sequentially sent out to the front edge 40a side of the bed plate 40 while being handled and placed on the conveying surface of the conveyor belt 30 of the supply conveyor 3. thing (second thing)
is automatically supplied to the supply port 2 of the threshing chamber 1.

At this time, the legumes G, which have peeled off and fallen off from the husks of the grain culm or the waste culm, are transferred to the conveyor belt 30 of the supply conveyor 3, as shown in FIG.
It rolls down on the conveying surface of the conveyor belt 30 on the downward slope side, falls from the rear end surface of the conveyor belt 30, and connects to the receiving opening of the conveyor gutter 5 located below the rear end of the conveyor belt 30.
