Description

Detailed Description of the Invention (Industrial Application Field) The present invention is used in a grain conditioning and storage facility that receives grain from each producer, undergoes drying, sorting, and storage processes, and then ships the grain. , the receipt of which is sometimes related to the improvement of the packaging in which samples are taken for self-certification of the grain quality of each producer.

(Prior art) Conventionally, this type of device weighs received grain in a weighing hopper, and when discharging the weighed grain from the meter B hopper, a sampling cup is advanced toward the discharge port of the weighing hopper. There is a known method in which the falling grains are collected in fixed amounts in a cup a predetermined number of times.

(Problems to be Solved by the Invention) By the way, the amount of grain brought to and received by each producer's facility generally varies.

As a result, when the amount of grain received is low, it is difficult to secure a certain amount of samples, which causes the problem of not being able to carry out appropriate self-tests.

Therefore, in order to solve this problem, the present invention aims to optimize self-inspection in a 1-1 manner so that the consignee can secure a constant sample of spears regardless of the amount of grain.

Means for Solving Problem C) In order to achieve the above object, the present invention is configured as follows.

That is, the present invention provides a sample collection mechanism in which a receiving device has a weighing hopper for weighing grains in fixed quantities, and a sample cup is used to collect samples for self-inspection multiple times in fixed quantities at a position facing the supply or discharge port of the weighing hopper. In addition, the sample collection mechanism is equipped with a sample replenishment cylinder that accommodates the replenishment sample, and both discharge sides of the sample collection mechanism and sample replenishment cylinder are connected to a sample measuring device. .

And sample collection mechanism 5 and sample replenishment cylinder 11
Both samples are supplied to the sample measuring device 15, so if the required amount cannot be obtained with only the sample taken with the sample cup 9 and there is a shortage, the shortage can be made up with the replenishment sample. A fixed amount of samples can be secured regardless of the amount of grain.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings.

In the figure, l is a large cargo receiver into which producers' grains transported by truck or the like to the grain adjustment and storage facility are loaded before being weighed, and the discharge port is equipped with an on-off valve 2 that can be opened and closed freely. establish.

Reference numeral 3 designates a weighing hopper into which grains from the hopper 1 are input and quantitatively counted, and an on-off valve 4 is provided at its discharge port.

This weighing hoe/bar 3 has a measuring device (not shown), and the measuring device outputs an electric symbol according to the amount of grain.

Reference numeral 5 denotes a sample collection mechanism that allows the receiver to look into the discharge port of the hopper 1, and collects a portion of the grain that falls from the discharge port into the weighing hopper 3 as a sample for self-inspection as will be described later.

As shown in FIG. 2, this sample collection mechanism 5 has a sliding plate 7 having a through hole 6 disposed on the discharge port side of the hopper 1, and connects the input port of a sample shooter 8 to the through hole 6. . Then, while the sample cup 9 whose bottom part is opened slides on the sliding plate 7, the receiver can freely reciprocate between the discharge port of the hopper 1 and the input port of the sample shooter 8 by means of a cylinder lO. The capacity of the sample cup 9 at one time is, for example, 2
00g.

Reference numeral 11 is a sample replenishment cylinder which is attached to the sample collecting mechanism 5, and which receives grain discharged from the hopper 1 as a replenishment sample. This sample replenishment cylinder 11 is provided with an on-off valve 12 that can be opened and closed at its discharge port, and has a sample overflow port 13 opened.

Reference numeral 14 denotes a sample transport path that guides the samples discharged from the sample shooter 8 and the cylinder 11 to the sample measuring device 15, and has a sample input port 16 into which samples collected elsewhere are input.

As shown in FIG. 3, the sample measuring device 15 has a weighing box 17 for storing and weighing a sample, and one side of the weighing box 17 is open, and a control valve 18 that can move up and down is installed in the opening. will be established. The control valve 18 is a female thread cylinder 19
The female threaded cylinder 19 is integrally connected to the lower end of the
are screwed together using a threaded rod 20 that is fixed in position and rotatable.

Therefore, the mWJ valve 18 can freely move downward by -1 by the rotational movement of the male threaded rod 20.

An on-off valve 21 that can be opened and closed is provided at the bottom of the weighing box 17, and the bottom is connected to two chute 23 via a chute 22. In addition, the control valve 18 of the measuring box 17

In the following embodiments, the sample collection mechanism 5 and sample replenishment cylinder 1 were installed at the discharge side of the hopper 1, that is, at the supply port of the weighing hopper 3; Of course, it may also be provided at the exit.

Next, an example of the operation of the embodiment configured as follows will be described with reference to the drawings.

Now, when weighing in the weighing hopper 3 starts, the on-off valve 2 of the hopper 1 opens and the grains fall into the needle end hopper 3.

Accordingly, as shown in FIG. 2, the sample cup 9 advances to the discharge port of the hopper 1, and a part of the falling grain is collected as a sample. When the sampling is completed, the sample cup 9 returns to the input port of the sample shooter 8 shown by the solid line, and the sample in the sample cup 9 is input into the sample shooter B from the open bottom. The introduced sample is stored in the weighing box 17 of the sample weighing device 15 via the sample transport path 14.

Here, it is assumed that the sample cup 9 is reciprocated, for example, five times at equal intervals, until the weighing hopper 3 becomes full and reaches a quantitative state (for example, 200 kg) to collect the sample.

On the other hand, a part of the grain that falls into the weighing hopper 3 is stored as a replenishment sample in the sample replenishment cylinder 11, and when a predetermined amount of grain is stored up to the overflow port 13, the replenishment sample stored thereafter is It overflows into the weighing hopper 3 from the overflow port 13.

Next, when the weighing hopper 3 is full and the on-off valve 2 of the hopper 1 is closed, the on-off valve 12 of the sample replenishment cylinder 11 is opened and the replenishment sample in the cylinder 11 is transferred to the sample scale. 15 into the weighing box 17.

By the way, the sample storage capacity of the sample car 7p 9 is set to 200 g, and the control valve 18 is set so that when the amount of sample stored in the weighing box 17 of the sample weighing device 15 reaches 1000 g, the sample overflows. It is assumed that there is

Under such conditions, when weighing is carried out with the measuring hos and pas 3 full, the weighing box 17 is filled with samples collected only in the sample cup 9, and the samples fall from the sample replenishment cylinder 11. All samples are in weighing box 1
On the other hand, when the cargo is overflowing and collected in the hopper 25, the weighing box 17 is full when the sample collected only in the sample cup 9 is weighed without the weighing hopper 3 being full. When the sample replenishment cylinder 11 is full, the remaining sample overflows from the measuring box 17 and is collected into the hopper 25.

Therefore, regardless of the amount of sample taken with the sample cup 9, the measuring box 17 of the sample measuring device 15 is full, and as a result, a predetermined amount of sample is always obtained.

When the on-off valve 21 opens, the fixed amount of the sample weighed by the sample scale 15 in this manner is transported to the sample dryer by the transport device 27 and dried.

(Effects of the Invention) As described in -1- below, in the present invention, in addition to the sample collection mechanism for collecting samples with a sample cup, a sample replenishment cylinder is provided, and a predetermined amount of replenishment sample is accommodated in this cylinder. Therefore, when there is a shortage of samples, the shortage can be filled with the replenishment sample. Therefore, the consignee can secure samples of a certain amount of grain regardless of the amount of grain, thereby making it possible to carry out appropriate self-inspection.

In addition, in the uninvention, a sample replenishment cylinder with a simple configuration is used as a means for collecting a replenishment sample, so the overall configuration is extremely simple and the cost per production can be reduced. .
