Background of the Invention Field of the Invention [0001] The present invention relates to a device for adjusting depth of a plant,

The present invention relates to an apparatus for adjusting depth of food in a transplanting machine, and more particularly, to a method and apparatus for adjusting depth of food in a transplanting machine, which can reduce the load caused by contact with the ground, To a depth adjusting device.

The transplanting machine according to the present invention can be regarded as a generic term for equipment that can be planted at a predetermined depth in a cultivation area after plants having a certain size grown on a tray are separated. Thus, for example, it is possible to use a plant for transplanting a certain crop as in an onion transplanting machine, and also applicable to rice planting rice planting. In the following embodiments, embodiments embodied through a rice-growing machine will be described, and a configuration example applied to a rice-growing machine will be described in the related art.

As shown in Fig. 1 showing a general rearing unit and Fig. 2 showing a food processing unit, the rearing unit includes a running vehicle 10 on which an engine as a power source for driving is mounted, And an eating apparatus 20 which is installed in the living room and is actually a living planting apparatus. The feeding device 20 is connected to the running vehicle body 10 through a plurality of links (three or four) mechanisms (12), and a hydraulic cylinder is installed in the link so as to be able to move up and down.

The driving body 10 is provided with an operation section 14. In this operation section, a plurality of devices for driving the driving body 10 and driving the food processing device 20 are provided. A pair of front wheels 16 and rear wheels 18 are provided on the frames of the vehicle body 10, respectively. And the planting of the food processing apparatus 20 proceeds with the running of the running body 10 itself.

The feeding device 20 is provided with a cooking frame as a basic frame for supporting the respective components constituting the connection to the running vehicle 10 and the feeding device. Such a food chasis includes a food part frame 21a provided in a lateral direction in the lower part, a pair of mothball tank support frames 21b vertically installed at both ends of the food part frame, And a roller support 21c installed to move the base plate in the left-right direction while connecting the base plates 21c to each other. In the middle portion of the moth tank supporting frame, a rolling support 21d is installed in the lateral direction to reinforce the strength of the entire food-portion chassis.

A plurality of floaters (22) are provided at the lower portion of the food frame, so that the depth of the food can be adjusted. In the vicinity of the plotter 22, there are provided a plurality of separation fingers 26 for separating a certain amount of hair from the base plate and planting the rice. A stopping device 24 is provided in front of the plotter 22 for performing a grounding operation for picking up the ground before planting the seedling. The stopper 24 is composed of a stationary rotor that rotates using the power of the engine, and a plurality of theorem blades installed on the outer side of the stationary rotor to select the ground.

Such a floater 22 can grasp the state of the ground by being in contact with the ground, and is used as basic information for controlling the depth of the food. A sensor is used to detect the state of the plotter 22. Specifically, a potentiometer for detecting the inclination of the plotter 22 is installed. The potentiometer (sensing sensor) senses the inclination angle of the plotter in accordance with, for example, an ascending or descending film, and transmits the sensed angle to the control unit (CPU).

Based on the inclination state information of the plotter, the control unit can control the depth of the food by controlling the hydraulic cylinder that moves the food processor 20 up and down. In addition to the height adjustment by the plotter, the depth of the food can be manually set or changed manually by the user. 2, a food depth control lever 28 is provided at the rear portion of the food processing apparatus 20. By manipulating the depth control lever 28, the depth of the food depth can be adjusted by interlocking the plotter .

The lever (29) provided adjacent to the food depth control lever (28) is a seedling weight adjustment lever that adjusts the amount of peel off from the base plate. The configuration in which the floater 22 is moved by the operation of the depth-of-cut-off depth adjusting lever 28 is well known, and a detailed description thereof will be omitted. The operation of the food depth control lever 28 is performed by separating the adjustment lever 28 from the plurality of holding grooves 28A formed in a row in the lever casing 28B ), And operating in the vertical direction.

In the conventional food processor having such a configuration, the operation of the depth-of-field adjusting lever 28 is performed in a state where the plotter 22 is in contact with the ground. However, since the food depth control lever 28 is substantially related to the movement of the plotter, it is necessary for the reaction force to follow the operation of the food depth control lever 28 while the plotter 22 is in contact with the ground . That is, according to the conventional configuration as described above, it is found that there is a disadvantage that a lot of inconveniences must follow the smooth and smooth operation when adjusting the food depth control lever 28.

SUMMARY OF THE INVENTION An object of the present invention is to smoothly move the food depth control lever by raising the food processor itself up to a predetermined height at the time of operating the operation lever in order to manually adjust the depth of the food in the pasture period, And to provide a food depth control device.

According to an aspect of the present invention, there is provided a traveling vehicle comprising: a traveling vehicle capable of traveling by an output from an engine; a floater mounted on the rear end of the traveling vehicle so as to be vertically movable by a lifting / lowering hydraulic cylinder, And a depth control lever coupled to the plurality of retention grooves arranged in a line for adjusting the up and down movement of the floater, the apparatus comprising: A float position detecting sensor capable of detecting a tilt value of the plotter; A depth-of-cutoff lever position sensor capable of detecting that the depth-of-cutoff depth control lever is moving to adjust the depth of the cutoff; And a control unit for controlling the lifting / lowering hydraulic cylinder so as to elevate the floater based on an adjusting lever sensing signal from the depth-of-field adjusting lever position detecting sensor.

According to the embodiment, the control unit controls the elevating and lowering hydraulic cylinder to raise the plotter within a range in which the inclination angle of the plotter is within a certain range.

According to the present invention, when the user senses the motion for adjusting the depth while performing the operation of releasing the depth-of-field adjusting lever from, for example, the holding groove, the controller raises the entirety of the food- I am lifted up. Therefore, the operation lever for adjusting the depth of the food can move more smoothly and accurately without reaction with the ground.

In the present invention, the elevation of the floater is limited to a substantially elevated position in which the plotter does not deviate from a certain angular range, that is, it is inclined only to a certain extent. According to this configuration, it is expected that the functions of 'automatic turning function' and 'line marker' do not need to be reset.

BRIEF DESCRIPTION OF THE DRAWINGS FIG.
Fig. 2 is an exemplary perspective view of the configuration of a vegetable rice planting device in a rice-growing season; Fig.
3 is a block diagram for explaining an apparatus for adjusting depth of food according to the present invention

The present invention will now be described in detail with reference to FIG. 3, which is a block diagram illustrating the structure of a depth-of-field adjusting apparatus according to the present invention. 1 and 2, if necessary, in the following description.

First, the control unit 100 in the present invention means a device such as a CPU for performing electrical control of the entire rice-growing machine. For example, the control unit 100 basically performs control of a corresponding component based on input signals of all levers or buttons operated by the operation unit 14 by the user.

The controller 100 also controls the hydraulic cylinder 110 that can raise and lower the food processor. For example, when a signal for lifting or lowering the food processing apparatus is input, the control unit 100 controls the hydraulic pressure to the up-down hydraulic cylinder 110 so as to substantially raise and lower the food processing apparatus 20 have.

The floater detection sensor 120 for detecting the state of the plotter measures the slope of the plotter according to the state of the ground on which the rice-growing machine is running. For example, the plotter detection sensor 120 can detect whether or not the current plotter has a slope that increases toward the front (or backward) and information about the slope angle. Therefore, the plotter position sensing sensor 120 senses information on the degree of inclination of the plotter 22 in which direction, and transmits the sensed information to the controller 100.

The control unit 100 controls the up-down hydraulic cylinder 110 so that the plotter 22 is at a reference position close to horizontal based on this degree. For example, the control unit 100 controls the hydraulic cylinder 110 so that the plotter 22 can be returned to the reference position by raising or lowering the food processor 20. [ Controlling the hydraulic cylinder here is accomplished by interrupting the oil entering and exiting the hydraulic cylinder as described above.

As described above, the depth of the food is related to the floater. When the floater 22 is elevated, the depth of the food is deepened, and when the floater 22 is lowered, the depth of the food is decreased. In order to manually manipulate the depth of the food, the depth of the food depth control lever 28 is provided on the back side of the food processor 20 as described above. It is also described in the related art that the manipulation of the depth-of-cutoff control lever 28 is mechanically connected to the upward or downward movement of the plotter 22.

The depth control lever 28 is coupled to any one of the plurality of retention grooves 28A formed in a row in the lever casing 28B to maintain the predetermined position of the plotter 22. [ In order to operate the food depth control lever 28, the adjustment lever 28 is moved in the horizontal direction and separated from the currently held holding groove 28A, and then moved to one side of the upper and lower sides.

According to the present invention, a food depth control lever position sensor (hereinafter, referred to as a 'lever sensor') 130 for sensing the movement of the control lever 28 can detect the movement of the control lever 28 Lt; / RTI > The lever detection sensor 130 may be installed at a position where the movement of the control lever 28 can be sensed, for example, in a lever casing 28B provided to surround the control lever 28. [

Any type of sensor can be used as long as the lever detection sensor 130 can detect the movement of the control lever 28 substantially. For example, it is also possible to use a potentiometer which is provided near the control lever so as to detect the positional shift of the control lever, and uses an optical sensor composed of the control lever 28 and a light emitting and receiving element provided in the vicinity thereof Of course it is possible. In addition, it is possible to use any sensor as long as it can sense the movement of the control lever 28. For example, it is possible to detect the movement of the control lever 28 in the holding groove 28A It is enough.

The detection signal from the lever detection sensor 130 is transmitted to the control unit 100. In response to the signal, the control unit 100 performs control to raise the up-down hydraulic cylinder 110 in order to enable smooth and smooth operation of the control lever. When the feeding device 20 is lifted by the hydraulic cylinder 110, the regulation state with the ground is canceled, so that the position of the plotter 22 is smoothly changed through the smooth operation of the control lever 28 It is because.

Here, the operation of the hydraulic cylinder 110 by the sensing signal from the lever sensor 130 must be performed within a certain range. If the hydraulic cylinder 110 is operated and the plotter 22 is completely heard, the settings related to the 'line strike line marker' and the 'automatic turning function' are deleted. That is, when the hydraulic cylinder 110 is operated and the plotter 22 is completely lifted in a state in which the operation is not completed, the control unit regards the operation as completed and deletes the set working condition.

Therefore, when the controller 100 operates the hydraulic cylinder 110 based on the detection signal of the lever sensor 130, it is necessary to set a new working condition when the floater 22 is fully lifted. 110 must be precisely controlled by the control unit 100 so that the operation can be performed within a certain range. Here, the fact that the floater 22 is lifted is substantially the same meaning that the inclination angle of the floater detected by the floater position detecting sensor 120 becomes a certain level or more. Therefore, when the control unit 100 operates the hydraulic cylinder 110 based on the detection signal from the lever sensor 130, the control unit 100 controls the inclination of the plotter 22 to a predetermined inclination angle (for example, 6 to 9 degrees) Should not be exceeded.

When the hydraulic cylinder 110 is operated by the control unit 100 and the food processor 20 ascends, the inclination angle of the floater 22 is detected by the floater position detecting sensor 120, . Accordingly, the controller 100 controls the operation of the up-down hydraulic cylinder 110 based on the inclination angle of the floater detected by the floater position detecting sensor 120, thereby controlling the operation of the up-down hydraulic cylinder 110 based on the upper limit height of the floater or the upper limit inclination angle of the plotter Control will be possible.

As described above, according to the present invention, the control unit 100 controls the up / down hydraulic cylinder 110 so as to ascend based on the signal from the lever sensor 130, which can detect the movement of the control lever 28. [ Which is the basic technical idea. It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
