Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to an on-off valve for a powder tank, and is intended to discharge grains, etc., once stored in a grain tank, a chute, etc. by opening the on-off valve. Can be used for on-off valves.

Problems to be Solved by the Invention It is difficult to completely discharge the internal powder and granules from a tank containing powder and granules by opening the on-off valve. It is difficult because it has an adhesive effect.

Means for Solving the Problem The present invention provides an on-off valve (1) of a tank (1) in order to collect powder and granular material inside and discharge it downward, and an opening (4) on which the on-off valve (2) should come into contact when closed. In addition, the on-off valve for the powder tank is configured to be opened and closed by opening and closing a plurality of times.

Functions and Effects of the Invention After a predetermined amount of granular material has been accumulated in the tank ■ with the on-off valve ■ of the opening ■ closed, when opening this on-off valve ■, the on-off valve ) is intermittently opened and closed multiple times, and vibrations are applied not only to this on-off valve (■) but also to the area around the opening 0 of the tank (1), and the powder and granules that try to adhere to these are vibrated. Being shaken down, the tank ■opening■
It is possible to smooth the discharge of powder and granules from the tank 0) and reduce the amount of powder remaining in the tank 0) after the on-off valve (2) opens. It is easy to operate because it is automatically performed by opening the opening part.

Embodiment In the example shown in Figure 1, the tank α) is formed in the shape of a vertically long rectangular tube, and the center part of the on-off valve (2) is supported inside the lower end by a rotating shaft 6). ) is provided with a guide plate 0 that slopes in an inverted V shape from the outer wall surface toward the rotation range of this on-off valve (2), and the tip of this guide plate (■) is opened. O) The edge part (2) is configured so that it can come into contact with the on-off valve (2) in the closed position. (2) is a discharge tube, which is located at the bottom of the opening (CI) and guides the discharged grains downward to the hopper (2). ■ is a solenoid installed outside the tank (1), and this actuator [phase] is connected to the arm ■
is connected to the rotating shaft (■) through the arm (■), and the solenoid (■) is energized against the return spring (■) provided on this arm (■) to open and close the valve (■).
It is configured to operate in an interlocking manner so that the opening operation is performed and the closing operation is performed by the tension of the return spring (■).

The tank (■) with such a configuration has a paddy supply hopper holder on the upper side of the zero machine frame (■) which is used as a descaling and sorting device for sample paddy as shown in Fig. 4, and the paddy is supplied from the paddy supply hopper @. Weighing hopper that receives and weighs the sample paddy ■, weighing device @ tiG
, a hopper ■ for receiving and frying the paddy supplied from this weighing hopper ■, a grain lifting machine 1171, etc. are provided on the other side, and an upper part for receiving and threshing the paddy fried by this grain lifting machine 071 on the other side. A husking device [F] and a wind sorting device 0 are installed, and a sorting device ω consisting of a rotating sorting tube that receives the wind-selected rice and sorts it into sized grains and waste grains is installed below the hulling device [F] and a wind sorting device 0. At the bottom of this, there is a weighing device M@ that receives and weighs the sorted grains that fall from this sorting device@, waste grains, etc. separately, a hopper@, and a sorted grain that is weighed and discharged by this weighing device@.

A grain lifting machine and mortar for frying waste grains, etc. is installed, and a container (e) for receiving grain size and waste grains is visible in the grain lifting machine.

The sorting devices O are provided in a pair on the left and right, and the removed rice can be switched between the left and right sorting devices and the chute between them by means of a switching gutter below the wind sorting device. The tank (2) is provided so as to look into the lower end of this chute (2), and the discharge gutter (2) at the lower end is seen over the hopper (8). In each sorting device), when the rotating sorting tube rotates forward, waste particles leak through the mesh on the outer periphery and the sorted particles remain inside, so by rotating the sorting tube in the opposite direction, the sorted particles inside are sorted out. It has a configuration that allows it to be discharged outside the cylinder.

θ is the operation panel, installed on the machine frame 0 section above the supply hopper 0 section,
It is equipped with an operation mechanism that can manually or automatically perform the interlocking operation of each of the above parts, the shutter operation of each hopper, the switching operation of the switching gutter, etc., and the opening and closing operation of the on-off valve (2) of the tank (1), The opening/closing operation of the on-off valve (2) multiple times can be automatically performed by the control mechanism inside the operation panel θ, and the switch of solenoid 0 is turned on after a few seconds. Automatic energization is to be performed as soon as possible.

When a predetermined amount of sample paddy is supplied from supply hopper 0 to weighing hopper ■, the total weight of this paddy is measured by the weighing device (G),
This weighed paddy is supplied to the hulling device [F] through the grain lifting machine 0 and is subjected to a-4, and the washed rice that has been wind-selected by the wind sorting device 0 to remove rice husk dust, etc. is transferred to the switching gutter (c). The grains are supplied to either the left or right sorting device 0, where they are sorted into sorted grains and waste grains, and the sorted waste grains are taken out to a weighing hopper@, weighed, and fried grains [123, and then taken out into a container@]. Afterwards, the sized grains are taken out to a weighing hopper Q, weighed, and taken out in the same way to another container (to) using a grain lifting machine, and the value of these waste grains or sized granules, etc., measured with the measuring device ① and the above-mentioned weighing The arithmetic unit calculates the dust particles, the waste mixture ratio, etc. based on the measured values etc. by the device ω.

When supplying the rice to the sorting device [phase] for sorting after carrying out the hulling action twice, leave the switching gutter facing up (into the chute) and close the on-off valve ■. Weighing device ω
The crushed rice weighed in the tank and crushed by the hulling device [F] is temporarily stored in this tank ■, and then freshly supplied and discharged through the weighing device ω, the hulling device ω, etc. In response to the fried rice, the fried rice that has been metered and supplied several times and stored in the tank ■ is allowed to flow down by opening the on-off valve (2). K (m) is again supplied to the hulling device ω part to perform the hulling action, and this twice-sanded rice is supplied to the sorting device 0 to be sorted into waste grains and grading grains. When the drained rice stored in ■ is discharged by opening the on-off valve (2), the on-off valve (2) opens with the activation of actuator 0 by the energization of solenoid Since the valve ■ is closed by the elastic force of the return spring ■, the opening/closing valve ■ is elastically struck by the opening edge (A), and this elastic striking force closes the opening/closing valve (not only the S-ring itself but also the tank 0). Since the rice is also vibrated, the rice that is about to adhere to the inner circumferential surface is smoothly flowed down and discharged.

Since there are no particles left in the tank that is discharged in this way, it is possible to accurately determine each mixing ratio by measuring waste particles, grading, etc., and also to accurately calculate subsequent similar effects. It is possible to maintain the grain size and reduce the amount of grains mixed with different grains, such as one type of grain.
