Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a feeding device for a color sorter for granular materials, etc.

A prior art color sorter removes foreign or poor quality grains mixed in grains or other granules based on differences in color.

This type of color sorting machine for particulate matter shines light on the falling particulate matter, catches foreign matter by changes in the amount of reflected light and transmitted light, and injects air or other fluid onto it to ensure normal flow. Sorting is done by blowing it away from the road.

However, the flow rate of the particulate matter on the downflow gutter varies depending on the flow rate, properties, type, etc., and it is difficult to accurately sort out the particulate matter. It needs to change.

However, if the inclination angle of the downflow trough is changed, the positional relationship between the downflow trough and the feeder changes, which disrupts the state of supply of particulates from the feeder to the downflow trough and the flow state of the downflow trough, making it impossible to perform a correct sorting action.

For this reason, it is necessary to move the position of the feeder according to the change in the inclination angle of the downflow gutter so that as much as possible, the grains flow down to the same location on the downflow gutter at a constant speed, but this makes the structure complicated and troublesome.

In addition, a grain sorting body having a concave portion extending into the flow gutter and into which the grains to be sorted are inserted one by one is attached to the flow divider plate of the feeder so that this concave portion faces the bottom of the flow gutter, and the vibration of the flow divider plate A feeding device for a color sorting machine has been proposed in Japanese Patent Publication No. 54-28336, which vibrates the regulating fluid together and feeds the grains to be sorted one by one through the concave portion. The inclination angle cannot be changed, and if the inclination angle of the downflow gutter is changed, the positional relationship between the flow straightener and the downflow gutter will change because the tip of the flow straightener is attached to the feeder's flow divider plate. Therefore, it is not possible to drop grains at a constant speed at the same point in the gutter.

In addition, a chute plate is installed at the end of a pier, etc. so that it can be moved up and down via a cylinder, etc. attached to the pier, etc., and the chute plate is installed at the end of the pier, etc. via a cylinder, etc. attached to the interior of the chute plate. A device for changing materials such as sludge and earth sand that is configured to operate telescopically is known as Japanese Utility Model Application Publication No. 50-84980. In order to uniformly inject sludge, soil, etc. horizontally above the transport station by changing the length of the telescopic chute plate using a telescopic cylinder, it is necessary to constantly change the feeding position, and to change the length of the chute plate. required cylinders, etc.

Purpose of the invention In order to solve such problems, the present invention automatically moves the supply section from the feeder in response to changes in the inclination angle of the downflow gutter, and the supply section from the feeder to the downflow gutter moves from the feeder to the downflow gutter. To provide a feeding device for a color sorting machine which is located in a fixed position and can adjust the flowing speed of particulate matter as necessary, stabilize the flowing state of particulate matter, improve work efficiency, and perform accurate sorting. This is the purpose.

Structure of the Invention The feeding device for a color sorting machine of the present invention is a color sorting machine in which a downflow gutter with a variable inclination angle is arranged following a feeder, and an intermediate pole is provided to communicate the feeder and the downflow gutter. The intermediate pole is movable with respect to the feeder, and its tip is attached to the downflow gutter.

Example Embodiments of the present invention will be described below with reference to the drawings.

In FIGS. 1 and 2, a color sorter 20 for granular materials is shown.
has a housing 13, a feeder 2 provided thereon, an intermediate pole 3, and a hopper 15, and the intermediate pole 3 is configured to be movable by sliding with respect to the feeder 2, and its tip is configured to be movable by sliding with respect to the feeder 2. It opens into the gutter 4 and is attached to the downstream gutter 4.

1 is an electromagnet installed below the feeder 2, which smoothly transfers the granules fed from the hopper 15 to the color sorter 2.
The feeder 2 is vibrated in order to feed the water into the downflow gutter 4.

The housing 13 is provided with a control device 16 for controlling the color sorter 20, a fluid ejecting device 8, a sorting housing 14, a downflow gutter 4, etc. As shown in FIG. 3, as shown in FIG. 3 slides below the feeder 2 and adjusts the distance thereof, so that the particulate matter from the feeder 2 can be sent into the downflow gutter 4, and the lower end of the downflow gutter 4 is inserted into the separation housing 14. A receiving port for a receiving shaft 10 is opened on the extension of the axis of the downstream gutter 4, and a reference plate 5 and a lighting device 12 are attached to one side of the inside of the separation housing 14, and A light receiving device 6 and a fluid nozzle 7 connected to a fluid ejecting device 8 are attached to the side surface, and the tip of the intermediate pole 3 is curved to follow the downflow gutter 4.

A discharge gutter 11 discharges particulate matter such as foreign matter blown away by the fluid nozzle 7.

Next, the operation of the color sorter 20 will be explained.

First, the downflow gutter 4 is fixed with the mounting device 9, and the shape of the granular material is
The mounting device 9 is set so as to have an appropriate inclination angle according to the size and weight.

In this case, if the downflow gutter 4 is steeply sloped, the feeder 2
The distance between the downflow gutter 4 becomes shorter, the intermediate pole 3 slides below the feeder 2, and the overlapped portion with the feeder 2 becomes larger.

In addition, when the slope of the downflow gutter 4 is made gentle, the distance between the feeder 2 and the downflow gutter 4 becomes long, and the intermediate pole 3 is connected to the feeder 2.
As the particulate matter slides downward, the overlapping portion with the feeder 2 is reduced, and in this way, the flow of granular objects is smoothly sent from the feeder 2 to the downflow gutter 4.

After adjusting the feeder 2 and the intermediate pole 3, the control device 1
6 to energize the electromagnet 1 to vibrate the feeder 2,
The interior of the separation housing 14 is illuminated.

In this state, granular materials such as grains are sent from the hopper 15 to the feeder 2.

The granules fed into the feeder 2 pass through the intermediate pole 3, flow into a certain location in the downflow gutter 4, fall through the downflow gutter 4 at a constant speed to the receiving shaft 10, and are collected in a predetermined container or the like.

If particles of different colors are mixed in with the falling object, the amount of light entering the light receiving device 6 will change, and the change in the amount of light will change the amount of electricity, which will activate the fluid ejecting device 8, causing air etc. The fluid is injected from the fluid nozzle 7 to blow off the abnormally colored particles from the flow path of normal particles, and the particles such as foreign substances are sent to the discharge gutter 11 and separated from the normal particles.

Effects of the invention As mentioned above, the device according to this invention has an extremely simple structure, and when adjusting the angle of the downflow gutter, the intermediate pole automatically moves relative to the feeder in accordance with the movement of the downflow gutter. There is no need to move the feeder, and the machine can be operated and worked easily.

In addition, it is possible to ensure that particulate matter flows from the feeder to the downflow gutter at a constant speed, and by constantly stabilizing the flow of particulate matter, the sorting process can be carried out with high sorting efficiency. It has the effect that it can be performed.
