Description

[Detailed description of the invention] "Industrial application field" The present invention consists of a grain-lifting spiral body vertically installed inside an outer shell body and consisting of a spiral blade wound around the outer periphery of a cylinder; The present invention relates to a vertical grain sorting machine consisting of a sorting net body which is inserted concentrically and has a large number of small holes for sorting grains.

"Conventional technology" As a conventional vertical grain sorter, for example,
There are some disclosed in JP-A-146475, JP-A-58-153562, and the like.

In each of the above-mentioned publications, a supply hopper for supplying unsorted grains and a storage tank for storing selected refined grains are installed inside an outer shell body outside the body. A grain lifting spiral body with spiral blades wound around it in the upward direction, a sorting net body having a large number of small holes through which the grain lifting spiral body is inserted concentrically, and these grain lifting spiral bodies and the sorting net body are placed relative to each other. and a driving means for rotating, while frying the grains fed from the supply hopper to the base of the grain lifting spiral body, remove small grains by the sorting net, and store the refined grains in a storage tank. It was something that was released.

Further, regarding a vertical grain sorting machine in which a plurality of units each consisting of the grain lifting spiral, a sorting net, and a drive means for relatively rotating the grain lifting spiral and the sorting net are housed in parallel in an outer shell. Japanese Patent Publication No. 59-150580
There is something disclosed in the publication No.

The device disclosed in Japanese Patent Application Laid-Open No. 59-150580 is capable of increasing the amount of grain lifted by several times as compared to a normal vertical grain sorter equipped with a single unit.

However, today, these vertical grain sorters are required to: (1) increase the amount of grain lifted per unit time, that is, increase the grain lifting capacity, and (2) increase the ability to remove small grains from unsorted grains, that is, the selection rate. At the same time, it is required that the desired selection rate be freely obtained, and 3. The crushing effect of good grains be minimized during the sorting action.

``Problems to be Solved by the Invention'' However, conventional vertical grain sorters have various difficulties in simultaneously satisfying the various functions required today.

In other words, in order to simultaneously increase the grain lifting ability and the sorting rate, it is necessary to increase the rotation speed of the grain frying spiral and increase the agitation, thereby minimizing the crushing of good grains. This results in a result that goes against the third request, which is to stop the spread of the virus.

In addition, in order to obtain a desired selection rate, there was a problem in that it took time and effort to replace the sorting net and mix the discharged small grains with the refined grains later.

Also, according to Japanese Patent Application Laid-open No. 59-150580,
This is simply a plurality of the above-mentioned units made of grain-lifting spirals, etc., and does not contribute in any way to the above-mentioned requirement of simultaneously improving grain-lifting performance and grain milling rate.

The present invention was created by focusing on these conventional problems and requests, and allows for a gentle sorting action without damaging good grains, while also allowing the desired selection rate to be freely obtained. The object of the present invention is to provide a vertical grain sorting machine that can increase grain frying capacity without requiring much effort.

``Means for Solving the Problems'' The gist of the present invention to achieve this purpose is to provide a supply hopper for supplying unsorted grains and a storage tank for storing selected refined grains outside the body. A sorting net consisting of a grain lifting spiral body in which a spiral blade is wound around the outer periphery of a cylinder and facing in an upward direction during rotation, and a large number of small holes through which the grain lifting spiral body is inserted concentrically. and a drive means for relatively rotating the grain lifting spiral and the sorting net, and the grains fed from the supply hopper to the base of the grain lifting spiral are sent to the grain by the sorting net while being fried. In the vertical grain sorting machine that removes small grains and discharges fine grains into the storage tank, the grain lifting spiral, the sorting net, and the drive for relatively rotating the grain lifting spiral and the sorting net. a first sorting functional unit which directly receives unsorted grains from the supply hopper provided at the rear of the outer shell and discharges primary grain; A second sorting functional unit that receives the refined grain at the base of the grain lifting spiral and discharges the refined grain into the storage tank is housed in the same shell body in tandem, and the first sorting functional unit is located between the two sorting functional units. A small grain tank is provided on one side of the shell body to receive small grains discharged from each sorting functional unit, and in the small grain tank, the sorting a small grain sorting net body having small holes smaller than the small holes of the net body and further separating the small grains into good quality small grains and waste grains; A small grain sorting mechanism consisting of an auger part for supplying to the base of the sorting net is provided, and the fine grains separated by the small grain sorting mechanism are received and pumped to the fine grain storage tank. The present invention relates to a vertical grain sorting machine characterized by being provided with a grain conveying means.

"Action" Feed unsorted grains to the supply hopper and start each sorting functional unit.

The grains ascend through the first sorting functional unit, are successively subjected to sorting action, are fried while discharging small grains, are discharged as primary milled grain from the outlet of the first sorting functional unit, and are fried by the second sorting functional unit. It is fed to the base of the grain spiral.

The primary grain is further subjected to a sorting action by a second sorting functional unit, and the fine grains, which have been fried while discharging small grains, are transferred from the outlet of the second sorting functional unit to the supply tank of the shell body. is discharged into a storage tank located on the opposite side.

Since an intermediate tank having sufficient storage capacity is provided between the first and second sorting functional units, even if the rotation speeds of the first and second sorting functional units are changed midway, the The supply of primary grain to the second sorting functional unit will not be cut off, nor will grains overflow into the outlet of the first sorting functional unit.

In this vertical grain sorter, two sorting function units are connected in tandem, so the process length of the sorting action is doubled compared to the conventional single base type, and each sorting function unit The sorting action by this method eliminates the need to violently agitate the grains by forcibly increasing the rotational speed or violently collide them with the sorting net, as in the past, and allows for a gentle sorting action to ensure that good grains are Not subject to crushing action.

The small grains discharged from each sorting functional unit are collected in a small grain tank provided on one outer side of the outer shell.

The small grains collected in the small grain tank are supplied to a small grain separation net in this section, and are further separated into large and small small grains. Then, taking into consideration the condition of the milled grain and the desired grade, the small grain conveying means is activated at a timely manner to select good quality small grains from among the small grains separated by the small grain sorting net. Mix the grains into the refined grain storage tank.

The final refined grains are then discharged from the discharge port 59 on the second sorting functional unit 50 side to the storage tank 15 and temporarily stored therein.

In order to perform fine sorting, for example, the sorting net 32 on the first sorting functional unit 30 side may have coarse holes 32a, and the next sorting net 52 may have finer holes 52a.

By the way, it is extremely difficult for the milled grain in the storage tank 15 to reach the desired grade without too much or too little, and there are cases where the milled grain exceeds the desired grade and excessive small grains are discharged, resulting in uneconomical results. be. On the other hand, some of the discharged small grains remain of fairly good quality.

Therefore, the auger main body 74 is started while taking into consideration the condition of the polished grain and the desired grade, the small grains are moved to the supply hole 72a side, and the small grains are supplied to the base of the sorting net 76.

The sorting net 76 discharges waste grains from its small holes while rotating, and sends small grains of good quality to the left in FIG. Then, the on-off lever 80 is operated to open the on-off valve 79, and the bucket conveyor 87 is operated to send the high-quality small grains to the storage tank 15.

The transport section 85 and the auger section 73 can be easily operated using push buttons on the operation panel (not shown), and the on-off valve 78 can be operated simply by operating the on-off lever 79, so that small grains of good quality can be easily operated. The mixing operation is extremely easy, and the above operations can be carried out at any time and at will. Not only can you freely obtain the desired grade of milled grain, but you can also use high-quality small grains without wasting them, reducing the cost of grains. This is something that can be reduced.

"Effect of the invention" According to the vertical grain sorting machine according to the present invention, sorting functional units that perform a sorting action are provided in a column, and high-quality small grains are separated from small grains and the grains are milled at any time. By mixing it with grains, we not only achieved high grain frying efficiency and sorting rate at the same time, but also freely obtained milled grains of the desired grade, which also greatly contributed to reducing the cost of grains.
