Description

[Detailed description of the invention] This invention relates to a legume sorting machine configured to separate and sort sized grains by supplying the material to be sorted to the sorting surface of an endless sorting belt installed in a box-shaped frame. It is an object of the present invention to provide a device devised so that the sorting belt does not get caught in foreign matter and operates smoothly at all times to perform a smooth and reliable sorting action.

Hereinafter, the configuration of a specific example of the present invention will be explained in detail with reference to the accompanying drawings.

Fig. 1 shows the overall external appearance of the pulse sorter according to the present invention, Fig. 2 is an enlarged side view in the direction of the X arrow in Fig. 1, Fig. 3 is an enlarged view of the main parts, and Fig. 4 is the same as Fig. 3. FIG. 5 is a developed sectional view showing the internal structure of the entire pulse sorting machine.

The pulse sorting machine consists of an auxiliary sorting belt mechanism A housed in a base frame 1, a particle sorting rotary net barrel mechanism B1, a main sorting belt mechanism C housed in a box-shaped frame 2 installed above the base frame 1. Conveyor mechanism D1 that supplies the material to be sorted to the main sorting belt mechanism C
It consists of a winnowing mechanism E with a supply hopper 3, etc., and the operating parts of each mechanism are interlocked and connected to a power source by a drive mechanism to perform a predetermined operation, and the related arrangement is as follows.
It is done as shown in the figure.

In other words, the materials to be sorted that are introduced into the supply hopper 3,
The material to be sorted is configured to flow down a passage in the winnowing mechanism E in an appropriate amount, undergo wind selection pretreatment in the winnowing mechanism E, and then be delivered to the conveyor mechanism, and is conveyed to the upper end of the conveyor mechanism. is supplied from the input hopper 4 onto the sorting working surfaces 5a, 5a of the sorting belt 5 of the main sorting belt mechanism C.

The sorting belts 5, 5 are configured so that, by their rotation, only the sorted particles are separated and taken out from the outlet ports 5b, 5b, and other waste particles, foreign matter, etc. are allowed to flow down to the auxiliary sorting belt mechanism A. The group of particles to be taken out is introduced from the outlet ports 5b, 5b through the guide passage 6 into the rotating mesh barrel mechanism 7 for particle sorting, and the particles are classified by size and collected into collection tools 8a, 8b, 8c, respectively. The waste grains other than the sized grains are supplied to the auxiliary sorting mechanism A for further sorting, and the second grains are collected at the second port 9, while the others are returned to the karawine mechanism E part through the flow path 10,
After being subjected to re-selection by the mechanism, it is configured to be supplied to the conveyor mechanism again.

The main sorting belt mechanism C is constructed by winding and hanging the sorting belts 5, 5 in upper and lower stages in the box-shaped frame 2 by rotating wheels 11.11, and each sorting belt 5, 5 is It is tilted so that the front side of the rotation direction A in the rotation direction A on the upper side of the sorting surface 5a, 5a is on the upper side, and
It is installed so as to be inclined in the width direction, that is, in the direction orthogonal to the belt rotation direction A, and the corner portion corresponding to the upper part of the inclination in the width direction of the sorting belts 5, 5 is the lower part of the inclination in the rotation direction A. A supply passage 12.12 is opened in the box-shaped frame 2,
A distribution path of the input hopper 4 is connected to each supply path 12.12, and the materials to be sorted flowing out from the hopper 4 are fed onto the sorting working surfaces 5a, 5a, and the materials to be sorted are transferred to the sorting belts 5, 5. The grains are separated into regular grains and other grains by rotation in the direction of A, and the grains are collected at the take-out ports 5b and 5b installed at the bottom in the width direction of the belt, while other waste grains are collected by the rotation of the belt. The structure is such that it can be supplied to the auxiliary sorting sheet mechanism A from the upper communication section in the direction A.

The frame wall 2a of the box-like frame 2 in which the take-out ports 5b, 5b are installed has a non-sorting working surface 5c of the sorting belts 5, 5,
5c side, that is, the rotation side in the direction opposite to A, is provided with appropriately sized jammed object release holes 13.13 corresponding to the belt side end ears 5e, 5e, and the belt side end ears 5e, 5e and the frame. Bits and the like that are caught and moved between the body wall portion 2a and the body wall portion 2a are discharged to the outside of the box-shaped frame body 2 through the release holes 13 and 13.

In addition, 14 is an inclination angle adjustment mechanism of the main sorting belt mechanism C;
5 is an inclination angle adjustment mechanism of the auxiliary sorting bed mechanism A, 16 is an inclination adjustment device of the rotary mesh barrel mechanism B, 17 is a distribution valve, 18 is an over-reduction cylinder, 19 is a winnowing fan, 20at 20
In the bt 20c, the rotary wheel body 11 on the free rotation side around which the sorting belt 5 is wound is movable and fixed in the rotating direction A of the sorting belt 5 as appropriate for sorting.

This is a tension adjustment mechanism that controls the tension of the belt 5.

Main sorting belt mechanism C of the embodiment apparatus configured in this way
Now, while the group of materials to be sorted flowing out from the input hopper 4 to the corners on the sorting working surfaces 5a, 5a is spread on the working surface and being transferred by the rotation of the sorting belts 5, 5 in the A direction and the The grains are made to flow down the slope in the width direction of the belt to the outlet 5.
b, 5b, foreign matter such as waste grains that are irregular in shape and difficult to roll compared to regular grains, and are light in weight are carried to the sorting action surfaces 5a, 5a end at the end where rotational force is improved, and are subjected to auxiliary sorting. Be1
・It performs a separating action by dropping it into mechanism A.

While the separation action by the rotation of the sorting belt continues, the ends in the width direction of the belt where the take-out ports 5b, 5b are installed are, so to speak, at the lower end of the slope, so that the sorting action surfaces 5a, 5a are separated from the input hopper 4. When the material group to be sorted flowing out to the upper corner is spread on the working surface, the material falling from between the sorting belts 5, 5 and the box-shaped frame 2 is on the non-sorting working surface 5c, 5c.
It flows down along the side slope, and also on the sorting surface 5a of the belt.
Foreign matter such as dust flowing down along the slope of the belt tends to get caught in the gap between the belt end ears 5e, 5e and the frame wall 2a, and their stagnation prevents normal separation action. This is likely to cause an abnormal tension to get caught between the rotary wheel body 11.11 on the lower side of the upper slope and the sorting belts 5, 5, causing damage to the belt side edge portions 5e, 5e in particular. In this invention, foreign objects that become trapped are
It is carried by the operation of the belt, and the sorting action surfaces 5a, 5
The material is automatically discharged from the box-shaped frame 2 through the removal holes 13, 13 at a location that does not affect the amount of water a, thereby ensuring a good separation effect at all times.

Since the present invention is structured and operates as described above,
At the beginning, we have discovered that it is possible to realize a device with an extremely simple configuration that can perform good sorting without foreign objects getting stuck between the belt ears and the frame wall while the sorting belt is operating. The stated purpose was achieved.
