Description

Salt extraction device of saltfield

The present invention relates to a salt collecting device, and more particularly, to a salt collecting device that allows the salt produced in a salt field to be safely and quickly collected automatically using a crane and an inhaler.

Salt collection has been accomplished by a method in which a worker scrapes and collects salt with a tool such as green onions in a salt field, and transports it with a shovel in a transport vehicle. However, as is known, this method requires a lot of labor and working time in that salt is directly collected by manpower, and there is a problem that increases cost due to a decrease in productivity.

In the past, various salt harvesting methods that reduce labor and improve productivity have been partially proposed. For example, it could be an automatic cutting device that can scrape and store salt from the bottom of a salt farm. In addition, as another example, Korean Patent Registration No. 10-1223416 proposes a device for collecting salt by using a moving wheel for simple movement, and driving a power driving wheel that is driven by power when collecting salt.

However, the above-described conventional techniques still have a problem in that an operator must perform some work (for example, a work of collecting salt with a shovel) when collecting salt. That is, some work processes use power to improve the efficiency of salt collection, but still, the workers themselves must perform the work themselves, such as collecting salt in the salt extraction operation, so sufficient improvement effects could not be expected. .

An object of the present invention is to solve such a problem, and an object of the present invention is to provide a salt collecting device capable of sufficiently improving labor reduction and productivity improvement by completely automating the salt extraction process in a salt field.

In other words, the entire process of directly inhaling salt produced in the salt field from the salt field floor, and supplying and loading the inhaled salt to a supply truck provided at a predetermined location is performed automatically, thereby minimizing the labor force of workers and It can be said that it provides the purpose of not only improving productivity, but also preventing workers' safety accidents.

According to the present invention for achieving the above object, a pair of rails installed in equilibrium outside the salt field, which is a predetermined working space; A crane moving along the rail and comprising a pair of vertical frames and a horizontal frame connecting the vertical frames; A suction pipe that is coupled to the horizontal frame and is adjusted in a vertical direction according to a salt collecting operation and moves in a left and right direction of the horizontal frame; A supply pipe having one end connected to the suction pipe and the other end positioned above the supply truck to supply salt delivered from the suction pipe to the supply truck, and configured in a stretchable structure; And it provides a salt collecting device including a control box for operating the command for the salt collecting operation.

The suction pipe, the head portion coupled to the horizontal frame; A suction part facing the salt farm floor; A body portion having a multi-stage structure connecting between the head portion and the suction portion; And a sensor mounted at the front end of the suction unit and configured to detect a distance from the salt farm floor, and the sensor sends a sensor signal to the control box to stop driving for adjusting the length of the suction pipe when it reaches a preset value. Print.

The control box includes a power switch for power on/off; A receiver for receiving the sensor signal; A mode switch for selecting a moving path of the salt collecting operation; When power is applied, while moving the crane and the suction pipe along the work path selected by the mode switch, it includes a control unit for collecting salt and controlling the collected salt to be supplied to a supply truck.

Here, the control box further includes a memory for storing photographing information of the salt farm floor photographed by the camera, and the control unit moves the crane and the suction pipe to a location where salt remains based on the photographing information to add a salt collecting operation. To do it.

According to the salt collecting apparatus of the present invention as described above, a crane that can move along a rail is installed around a salt field that produces salt, and an inhaler that moves in the left and right directions and up and down directions is provided on the crane. And it provides a control box for controlling the movement of the crane and the inhaler. Therefore, the present invention has the effect that the operator can easily collect the salt produced in the salt farm by a crane and a suction machine that is automatically operated only by operating the switch at the beginning of the work.

In addition, the collected salt is supplied to a supply truck through a predetermined passage. As such, the present invention automates the entire process of the salt collection operation, and thus, an effect of reducing labor and improving productivity of the worker can be expected.

Hereinafter, the present invention will be described in more detail based on the embodiment shown in the drawings. As shown in FIG. 1, a pair of rails 11 and 12 are installed around the salt farm 10 of a certain area. The rails 11 and 12 may be installed in a pair on the left and right sides or upper and lower sides of the edge of the salt field 10, and the drawings show a state installed in the long direction of the salt field 10.

A crane 100 is installed on these rails 11 and 12. The crane 100 includes a pair of moving wheels 101 moving along the rails 11 and 12, a vertical frame 110 extending upwardly from the moving wheel 101, and the vertical frame ( It consists of a horizontal frame 120 connecting the upper portion of 110). And the crane 100 can be manufactured in various sizes (that is, the size of the vertical frame and the horizontal frame) according to the width of the salt farm 10, and also supports the horizontal frame 120 when the size of the crane increases. The vertical frame 110 for may be configured in plural. For example, as shown in FIG. 1, when the vertical frame is viewed from the side, it is configured to have a structure that distributes weight such as a triangle, so that the horizontal frame 120 can be stably supported.

Here, the rails 11 and 12 will not necessarily need to be installed. That is, even if the rails 11 and 12 are not installed, if the crane 100 can be sufficiently moved from the edge of the salt field by the moving wheel 101, the salt collection work can be performed without installing the rails 11 and 12. Because there is.

The horizontal frame 120 is provided with a suction pipe 130 for sucking salt on the bottom of the salt pan 10. The suction pipe 130 is installed downward from the horizontal frame 120 toward the salt farm floor and is configured to be adjustable in length like an antenna. That is, when salt is not collected, the suction pipe 130 has the shortest length as possible, and during operation, the length of the suction pipe 130 is extended to the bottom of the salt field for salt collection. The length adjustment of the suction pipe 130 is performed by the first motor 131a installed in the head part 131 to be described later. In addition, the suction pipe 130 moves in the horizontal direction of the horizontal frame 120. The movement in the left and right direction is performed by the second motor 131b (see FIG. 3) installed in the horizontal frame 120.

That is, the suction pipe 130 is configured to be able to adjust the length in the vertical direction and move in the left and right directions in a state in which the suction pipe 130 is coupled with the horizontal frame 120. Looking at the configuration of such a suction pipe with reference to FIG. 2, the head portion 131 coupled to the horizontal frame 120, the suction portion 132 for inhaling salt, and between the head portion 131 and the suction portion 132 Consist of the body portion 133, the body portion 133 is made of a multi-stage structure that can be adjusted in length by the first motor (131a) as described above.

The second motor 131b is installed in the horizontal frame 120 as described above. According to the forward rotation or reverse rotation drive of the second motor 131b, the head part 131 will be moved in the left or right direction in the horizontal frame 120, and the drawing for such movement in the left and right directions. Although not shown in detail, a power transmission member such as a belt and a gear that transmits power must be connected between the second motor 131b and the head 131.

Meanwhile, a method of combining the horizontal frame 120 and the head part 131 is various. For example, although not shown in the drawing, a guide groove is formed in the horizontal frame 120, and the head portion 131 is formed according to the driving force of the second motor 131b while the head portion 131 is mounted in the guide groove. Can be moved along the guide groove. Alternatively, coupling by magnetic force may be possible. That is, if a magnetic material that moves left and right is installed in the horizontal frame 120 and the contact surface of the head part 131 is formed of a material that reacts with the magnetic material, the head part 131 will also be movable according to the horizontal movement of the magnetic material. .

In addition, a suction pump 131c is installed in the head part 131 together with the first motor 131a. The suction pump 131c is a pump that provides a driving force for sucking salt from the salt farm floor, and is connected to a supply pipe 150 to be described later to deliver the sucked salt to the supply pipe 150.

According to this configuration, the suction pipe 130 is driven in the horizontal direction and the vertical direction of the horizontal frame 120, and the crane 100 can move in the front and rear direction, so that it is at all positions of the salt farm 10 The suction pipe 130 may be positioned. And this positional movement means that substantially all of the salt produced in the salt field 10 can be sufficiently inhaled.

It is important to adjust the distance of the suction pipe 130 with the bottom of the salt farm. This is because although it varies depending on the performance of the suction pump 131c, if the distance between the end of the suction pipe 130 and the bottom surface is far or too close, it is difficult to smoothly suck the salt in the salt farm.

Accordingly, as shown in FIG. 2, at least one sensor 135 is mounted at the front end of the suction pipe 130, that is, the suction part 132. The sensor 135 is a sensor that detects distance adjustment, and serves to output a sensor signal according to a preset value. Here, the sensor signal is a command for stopping the operation of adjusting the length of the suction pipe 130.

As described above, in the embodiment of the present invention, the suction pipe 130 has a multi-stage structure in which the length can be adjusted. However, in the present invention, while the suction pipe 130 has a fixed length, the height of the vertical frame 110 may be adjusted to provide the same effect. That is, the present invention can be applied to various configuration examples according to the size and characteristics of the salt farm.

In the present invention, a configuration for improving the efficiency of the salt extraction operation in the salt field 10 may be added together with the sensor 135. As an example of such a configuration, it may be a camera 140 for photographing the bottom of the salt field 10. As shown in FIG. 1, the camera 140 is mounted on the horizontal frame 120, so that the size of the salt field 10 may be photographed before the salt collection operation and the information may be provided. Here, photographing the size of the salt field 10 is to properly control the movement of the crane 100 and the horizontal movement and length adjustment of the suction pipe 130. In addition, the camera 140 may provide salt information that may remain in the salt field after the salt extraction operation.

A supply pipe 150 is connected to the suction pipe 120. The supply pipe 150 is for supplying the sucked salt to the transport cart 160, one end of the supply pipe 150 is connected to the head 131 of the suction pipe 120, and the other end is at the top of the transport cart 160. Located.

In addition, the supply pipe 150 has one end connected to the suction pipe 130, and when the suction pipe 130 moves in the left and right direction, the supply pipe 150 also moves correspondingly, so the supply pipe 150 has to be constructed in a stretchable structure. It is natural. For example, it is a bellows tube with adjustable length. Therefore, even if one end of the supply pipe 150 moves together with the suction pipe 130, the other end of the supply pipe 150 is always fixed to the top of the transport cart 160 to supply salt.

The transport cart 160 for receiving and transporting salt is configured to be synchronized with the moving speed of the crane 100. The carriage 160 may be an unmanned vehicle or a vehicle driven by a driver. Such a transport cart automatically controls the speed based on the moving speed of the crane 100 transmitted by the control box 200 to be described later, or is directly adjusted by the driver.

However, the carriage 160 will not necessarily need to be moved by the driving force. For example, if the length of the supply pipe 150 is formed sufficiently long, the transport cart 160 can be supplied with salt while being stopped at a predetermined position. Of course, in this case, it would be better to further include a supply pump (not shown) in the supply pipe 150 to sufficiently supply salt as long as the length is longer.

A control box 200 is installed that controls a series of processes of salt extraction. The control box is preferably installed in a position that can be easily manipulated by an operator, and may be installed, for example, on one side of the vertical frame 110.

As shown in Fig. 3, the control box 200 includes a power switch 202 for power on/off, a receiver 204 for receiving a sensor signal, and the photographing information and sensor signals of the camera 140 after the power-on operation. Accordingly, a control unit 206 is provided that controls the operation of the crane 100, the suction pipe 120, and the supply pipe 130 to control the salt extraction operation.

In addition, the control box 200 is configured with a mode switch 208 for selecting a work path. Here, the work path refers to the path for salt extraction in the salt farm, and the path that proceeds repeatedly in the left-right direction, such as from left to right, and then from right to left, and the path that goes up and down, such as from top to bottom, and back to bottom. This is the path to proceed. And to choose this path. The selection of the route can be selected by the operator according to the salt farm size and workload. In addition, as other progress paths, any number of paths running in a diagonal direction may be provided.

And the control box 200 further configures the memory 209. The memory 209 stores information photographed by the camera 140 and location information in a salt field where salt remains based on the photographing information. The location information is obtained based on the locations of the currently working crane 100 and the suction pipe 130. The memory 209 may further collect the salt remaining in the salt field after the salt extraction operation.

Next, we will look at the work of extracting salt from the salt field. Salt collection according to the present invention should be in a state in which rails 11 and 12 are installed at the edges of the salt farm 10, and the crane 100 is installed on the rails 11 and 12. In addition, the crane 100 must be in a state located in the initial position.

The initial position refers to the first position at which salt can be collected while moving the crane 100 from a predetermined position, and this position may be set by an operator or may be determined by information captured by the camera 140 . For example, it will be the corner of the salt field 10 or the part where salt collection should begin. And the initial position setting of the crane 100 is adjusted by the operator manipulating the handle (not shown) after power is applied.

In addition, when the crane 100 is positioned at the initial position as described above, the length adjustment process of the suction pipe 130 is performed to maintain an appropriate distance from the salt farm floor. This length adjustment is to drive the first motor 131a until the control unit 206 receives a sensor signal from the sensor 135.

According to this process, the preparation process for salt collection is completed, and when the operator operates the mode switch 208, the crane 100 moves in the forward direction along a predetermined work path, and the suction pipe 130 is a horizontal frame 120 ) To move left and right. And when the suction pipe 130 moves, the salt placed on the bottom surface of the salt farm according to the drive of the suction pump 131c will be sucked into the suction pipe 130, and it is continuously moved and supplied in the supply pipe 150 according to the driving of the supply pump. It will be supplied to the balance (160).

This process is repeatedly performed in the left-right direction or in the vertical direction along the progress path selected by the mode switch 208. Of course, once the horizontal or vertical direction is performed, for example, when salt is collected by moving from one edge to the other, the crane 100 moves forward along the rails 11 and 12. In this way, after the crane 100 moves forward, the above-described salt extraction operation is continuously performed.

And when the crane 100 moves, the supply truck 160 provided on one side of the crane 100 also moves at the same speed. Of course, if the supply pipe 150 is formed sufficiently long, the supply cart 160 may be in a stationary state outside the salt farm 10.

The supply of salt to the supply truck 160 may be continuously supplied or stopped by measuring the loading amount of the supply truck 160 and the amount of salt supplied through the supply pipe 150. And, when the loading amount of the supply truck 160 is full, it is natural that the salt collection operation should be temporarily suspended until the next supply truck 160 is provided.

In this way, it is possible to quickly collect the salt produced in the salt farm 10 by the crane 100 and the suction pipe 130 coupled to the crane 100, and the supply pipe 150, and the present invention allows the operator to perform a crane ( It can be said that it is different from the prior art in that salt extraction is performed by setting only the initial position of 100) and issuing a work order.

In addition, in the present invention, after the salt collecting operation, the operation of collecting salt remaining in the salt pan 10 may be further performed. That is, even if the above-described salt collection operation is performed, some salt may remain in the salt field 10. In this way, it is possible to completely collect the salt remaining in the salt field 10 because the camera 140 is installed in the crane 100.

The camera 140 transmits information about the salt field 10 to the control unit 206 from the beginning of the salt extraction operation after power is applied. Then, the controller 206 analyzes the photographing information transmitted by the camera 140 in real time, and determines whether salt remains in the place where the suction pipe 130 has passed. In addition, if it is determined that salt exists in a predetermined location according to the determination result, the location information is stored in the memory 209.

Therefore, when the salt collection operation for the salt field in operation is completed, the control unit 206 checks whether information for rework is stored in the memory 209. As a result of this test, if there is no information stored in the memory 209, the salt will be collected by moving to another salt field, and if there is information stored in the memory 209, the crane 100 is moved to the location and the remaining salt Make sure to collect perfectly.

Although it has been described with reference to the illustrated embodiments of the present invention as described above, these are only exemplary, and those of ordinary skill in the art to which the present invention pertains, without departing from the gist and scope of the present invention, It will be apparent that variations, modifications and other equivalent embodiments are possible. Therefore, the true technical protection scope of the present invention should be determined by the technical spirit of the appended claims.

That is, the present embodiment describes an example in which one crane is installed in a salt pond of a certain area, but since the size is different for each salt field, it is natural that a plurality of cranes may be installed in one salt pond during the salt extraction operation.
