Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a control device,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a preload control device for a general (full-feed) type combine, and more particularly, The present invention relates to a preload control device of a normal type combine that can be used.

Generally, the combine can be divided into a full feed type and a half feed type combine. Here, the full-feed type combine is also referred to as an ordinary type combine, and it can be said that it is constituted so as to obtain the whole grain through the threshing process in the inside of the threshing device by providing the entire cut interrupted portion inside the threshing device. The half-feed type combine refers to a combine type in which only a part of the cut pieces is fed to the inside of the threshing device to perform threshing.

First, a conventional full-feed type combine that is disclosed in Japanese Patent Application Laid-Open No. 2010-239980 will be described based on Figs. 1 and 2. As shown in the figure, a general pull-feed type combine is driven by a pair of crawler traveling parts 1 provided at the lower part of the main body frame 4 to perform a threshing operation in which the object is taken and the grain is separated from the cut- do. The combine is provided with a preloading unit 10 positioned forward with respect to the running direction and a threshing unit 5 threshing the cornstalks in a curved section cut by the preloading unit 10.

The curved portion cut at the preloading portion (10) is fed to the threshing device (5) through the feeder (11). The preload unit 10 is configured to be able to move up and down about a point through a hydraulic cylinder provided at a lower portion of the feeder 11 so that the hydraulic cylinder of the preload unit 10 is substantially used So that the height can be adjusted. The preloading unit 10 separates the crop to be cut and the crop that is not to be taken by a pair of left and right dividers 15 installed at a predetermined distance from the front.

Crops flowing into the inside of the pair of dividers 15 are cut by the cutting blade 16 while being pulled backward by the rotating raycril 17. The cut pieces thus cut are conveyed to the front side of the feeder 11 by the cut auger 18 and are conveyed by the feeder conveyor 11a provided in the feeder 11 to the rear of the threshing device 5 ). In the inside of the threshing device 5, a cylindrical threshing bucket is provided, so that threshing is performed to separate the curves from each other by the rotation of the threshing bucket.

The curled pieces separated from the threshing device 5 are conveyed to the grain tank 6 through a screw conveyor (not shown). The grain tank 6 is provided with an unloading mechanism for unloading the stored grains to the outside. Since this portion is not directly related to the present invention, a detailed description thereof will be omitted. The traveling, cutting and threshing of the combine is performed by operating an operating device such as various levers provided around the driver's seat 2. [

Such a general ordinary type combine is equipped with a horizontal control device, which is a device that allows the main body frame 4 to maintain its horizontal position. The horizontal control device includes a horizontal sensing sensor for sensing the horizontal in the front, rear, and left and right directions, and a plurality of hydraulic cylinders for maintaining the horizontal position of the main body frame 4 based on the sensing value sensed by the horizontal sensing sensor. .

It is also general that the height of the above-mentioned preload portion 10 in the normal type combine can be adjusted. That is, the height of the pre-installation part 10 can be adjusted by using a pair of hydraulic cylinders, so that the cutting height of the crop can be set. However, even if the cutting height of the crop is appropriately set, the soil may flow into the soil through the cutting part according to the ground state. For example, there is a fear that a cut portion comes into contact with a high inclined portion in front of the work, or a part of the take-up portion comes into contact with the ground in a severe inclined region in the left and right direction.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and it is a main object of the present invention to provide a combine that prevents soil from flowing in, such as a harvested crop.

Another object of the present invention is to provide an ordinary type combine which can perform the cutting work most efficiently by configuring the height of the example part to be adjustable.

According to an aspect of the present invention, there is provided a driving apparatus for a vehicle including a main frame for supporting a driving source, a traveling part provided on a bottom surface of the main frame, a horizontal sensor for measuring tilting in the left- A body horizontal control device configured by a plurality of hydraulic cylinders for adjusting the level of the body frame based on the sensed value, a body level control device installed in the front of the body frame to adjust the height through the pre- Is an example control unit of an ordinary type combine having a part. The preload control device according to the present invention further comprises preload detection means provided on a bottom surface of the preload portion and capable of detecting a tilt in the left and right direction of the preliminary portion itself and a tilt of the front uphill or downward tilt; And a control unit for controlling the horizontal adjustment of the body frame and the height adjustment of the preloading unit based on the sensing value of the sensing unit. Here, the control unit controls the body horizontal control apparatus so that the body frame also has the same inclination with respect to the right and left inclination of the preloading unit, and controls the cutting unit such that the cutting frame is raised or lowered with respect to the front uphill or downward inclination of the pre- .

According to a specific embodiment of the pre-attachment detecting means in the present invention, the upper end portion is rotatably installed on the bottom surface of the pre-loading portion via the support shaft, and the lower end portion is a pair of sensor plates contacting the ground surface. And a sensor for sensing the degree of rotation of the support shaft as the sensor plate rotates relative to the ground.

According to the present invention having the above-described structure, when the ground surface is tilted to the left and right while the cutting operation is in progress, the height of the main frame is adjusted so as to correspond to the height of the main body frame, . It is natural that the soil does not flow into the inside of the combine during the cutting operation by the operation of the pre-loading portion.

According to the present invention, the cut-off portion can be raised and lowered based on the detection value sensed by the sensor plate. In the case of entering the high inclined region from the front, by raising the cut-off portion in this manner, it will be possible to prevent the cut-out portion from contacting the ground. In this way, preventing the ground contact of the preliminary part means that the soil can be prevented from being introduced into the inside by the contact with the ground.

Hereinafter, the present invention will be described in more detail based on the embodiments shown in the drawings.

The combine to which the present invention is applied is a normal (full feed) type combine as described in the prior art. The combine according to the present invention includes a main frame for supporting an engine and the like, and a running portion (for example, a crawler running portion) provided on a lower surface of the main frame for traveling by the power of the engine . In order to maintain the horizontal position of the main body frame relative to the traveling part, the combine of the present invention includes a plurality of horizontal sensors (a sensor for detecting the inclination in the front-rear direction and a sensor for detecting the inclination in the lateral direction) And a body horizontal control device composed of a plurality of hydraulic cylinders controlled on the basis of the body horizontal control device. Such a horizontal control of the combine is a known technique practically applied to many current products, so a detailed description thereof will be omitted.

Also, the preload part 100 of the present invention is structured so as to be able to move up and down with respect to the traveling part. For example, as described above, using a pair of hydraulic cylinders, the elevation portion 100 can be adjusted in height relative to the ground, and this portion has been known for a long time, and at the same time, And a detailed description thereof will be omitted.

Therefore, in the present invention, the body horizontal control device of the combine is constituted by a plurality of hydraulic cylinders which are operated based on detection values of a plurality of horizontal sensors conventionally applied to the combine, Quot; means a device that allows the main frame to be kept horizontal relative to the main frame. The elevating and lowering device of the preloading section is defined as an apparatus including a pair of hydraulic cylinders provided on the preloading section and adjusting the height of the preliminary mounting section with respect to the main frame.

3, the harvesting section 100 of the combine harvester of the present invention includes a cutting blade 110 for cutting a stem of a crop and a cutting blade 110 for feeding the crop cut by the cutting blade 110 to the feeder 180 side (Not shown) for allowing the user to input the data. In addition, although the illustration is omitted, the preliminary part 100 includes a raycril for pulling the crop, and the cutting 110 cuts the stem of the crop drawn by the raycril.

As described above, not only the cutting edge 110, but also the cut auger and the laikrill are supported by the cutting frame 120 as well. Here, the cutting frame 120 includes a side wall 122 having a divider 124 at its tip and a connecting portion connecting the side wall. The cutting 110 may be substantially supported by the cutting frame 120.

According to the present invention, a skid 150 is installed on the bottom surface of the cutting frame 120. The skid 150 of the present invention can be said to be installed so as to limit the lower limit position of the preload part 100 substantially. Therefore, when the preload unit 100 is lowered, the skid 150 is installed at the bottom of the preload unit so that the skid 150 can be lowered as quickly as possible.

As described above, the preload unit 100 in the combine can be raised and lowered by a hydraulic cylinder. That is, in the pull-feed type combine, the pre-loading / descending device is provided so that the pre-loading part 100 itself can be raised and lowered relative to the main frame in order to determine the height of the crop during the cutting of the crop by the cutting blade 110 When the preload unit 100 is lowered by the preliminary lifting unit, the skid 150 will first come into contact with the ground.

According to the present invention, a pair of sensor plates Sa and Sb for measuring the degree of inclination of the ground where the crop is cut is disposed under the cutting frame 120. The sensor plates Sa and Sb are provided so as to be interlocked with a support shaft Ss supported on the bottom surface of the cutting frame 120. The sensor bracket 138 is connected to the support shaft Ss so that the sensor bracket 138 also rotates by the rotation of the support shaft Ss.

The rotation of the support shaft Ss is transmitted to the sensor lever 136 through the sensor bracket 138 since the sensor lever 136 is installed in the contact bracket 138 in a contact state. Since the sensor lever 136 is provided on the sensor 130, the rotation angle of the sensor lever 136 is measured by the sensor 130. [ The sensor 130 detects the rotation angle of the support shaft Ss by the sensor plates Sa and Sb through the sensor lever 136 and the sensor bracket 138 will be.

The upper ends of the sensor plates Sa and Sb are installed to be rotatable together with the support shaft Ss and the lower ends of the sensor plates Sa and Sb extend downward to be in contact with the ground. When the cutting operation is performed in this state, the sensor plates Sa and Sb can measure the tilt angle and the tilt angle in the forward and backward directions of the cultivating area in which the cutting operation is in progress.

By rotating the support shaft Ss using a separate motor, the sensor plates Sa and Sb may be rotated to a position at which the sensor plates Sa and Sb do not contact the ground, that is, the sensor shafts Sa and Sb. Therefore, even when the sensor plates Sa and Sb are not used, the sensor plates Sa and Sb can be rotated about the support axis Ss at the lower end upward, Or travel.

Hereinafter, the functions of the sensor plates Sa and Sb will be described in more detail with reference to FIG. 3 and FIG. 4. Referring to FIG. By configuring the pair of sensor plates Sa and Sb in the present invention, it is possible to detect the tilt in the left and right direction. That is, each of the sensor plates Sa and Sb is connected to separate sensors 138 and 139 (see FIG. 4). Therefore, it becomes possible to grasp the right-left inclination of the ground while the cutting operation is currently in progress.

The sensor plates Sa and Sb interlocked with the support shaft Ss of the cutting frame 120 are lifted up by their contact with the ground surface. The sensor plates Sa and Sb If there is a difference, a difference between the sensed values of the sensors 138 and 139 is generated based on the difference, which means the inclination angle substantially in the lateral direction. For example, if the difference between the sensed values of the pair of sensors 138 and 139 is large, it means that the left and right inclination is large, and if the difference of the sensed values is small, the difference of the right and left inclination is small. Therefore, based on the difference in detection values detected by the sensor plate Sb and the sensor 138 installed on the left side and the sensor plate Sa and the sensor 139 installed on the right side, It is possible to grasp the right and left tilts of the cultivating plants in progress.

Using the sensor plates Sa and Sb and the sensors 138 and 139 of the present invention, it is possible to grasp the ascent and descent tilt angle with respect to the traveling direction, in addition to grasping the left and right tilt angles as described above. That is, when two sensor plates Sa and Sb are sensed by the sensors 138 and 139, it can be seen that the area where the current weaving unit 120 is located is inclined upward. In the opposite case, it can be seen that it is a sloping area where the front is lowered.

Next, a control operation of the combine associated with the pair of sensor plates Sa and Sb of the present invention will be described with reference to FIG. The respective sensed values sensed in the pair of sensor plates Sa and Sb are transmitted to the sensors 138 and 139, respectively. The control unit 180, which has received the sensing values from the sensors 138 and 139, controls the main body of the combine according to the tilt state of the current cultivating area. The control unit 180 controls the main body horizontal control unit 192 of the combine based on the detection values of the horizontal sensors (composed of the left-right tilt sensor and the back-and-forth tilting sensor) conventionally mounted on the combine, Control is also possible.

First, when the place where the cutting operation is performed is inclined in the left-right direction, the two sensor plates Sa and Sb detect different values. Therefore, the control unit 180 can recognize that the region where the preload unit 100 is located (strictly separated from the position of the traveling unit) is in a tilted state. In the case where the cutting area where the preload part 120 is located is inclined in the left and right direction, it is necessary to control the body frame so as to have the same inclination as the preload part 120 in the horizontal direction.

Here, the horizontal control means a horizontal control for performing the cutting work most efficiently based on the preloading unit 100 as a reference. In other words, the sensor plates Sa and Sb detect the pair of sensor plates Sa and Sb, not the position of the traveling part, but the preliminary part for performing the cutting operation, and the body frame has the same inclination with respect to the right- . That is, the main body frame is also controlled to have the same inclination through the main body horizontal control device 192 so as to correspond to the preliminarily tilted state at a certain angle with respect to the left-right direction. As described above, the body horizontal control device 192 is composed of a plurality of cylinders in order to adjust the inclination of the body frame in the horizontal direction with respect to the traveling part.

When the main body is inclined to the same inclination as that of the preliminary mounting portion based on the right and left inclination detected by the preload portion 100, the preliminary mounting portion 100 can substantially perform the cutting operation in parallel with the ground do. Therefore, even if the ground surface is inclined, it is possible to work while keeping the preload part 100 in parallel with the ground surface, so that it is possible to prevent the ground from being in contact with the ground surface and thus the soil can be mixed with the harvested material .

As described above, on the basis of the operation (detection) of the pair of sensor plates Sa and Sb supported on the bottom surface of the cutting frame 120 so as to rotate as the support axis Ss, It is a basic function of the sensor plates Sa and Sb and the sensors 138 and 139 to be controlled so as to be parallel to the cutting frame. And this basic function will improve the actual cutting efficiency by virtually preventing the soil from being included in the harvest.

The second function of the sensor plates Sa and Sb is to ascertain whether or not the traveling combine is a sloping area. When the sensor unit is placed in an inclined region which gradually becomes higher with respect to the running direction, the pair of sensor plates Sa and Sb are brought into contact with the ground and lifted upward. The sensors 138 and 139 output sensing values corresponding to the sensor plates Sa and Sb to the controller 180.

Here, the control unit 180 recognizes that the forward direction is a high gradient, and controls the preliminary elevation / descent unit 190 to lift the severed portion to a higher position if possible. The raising of the cut-off portion in this manner is to prevent the soil from flowing into the inside by coming into contact with the ground where the pre-loading portion 120 is elevated. As described above, the second function of the sensor plates Sa and Sb in the present invention is to notify the manufacturing company 180 that there is a sloped surface that increases from the front. It is of course possible to have the same function for the inclined surface which is lowered or lowered.

The control of the present invention relating to the sensor plates Sa and Sb of the present invention has been described above. In addition to the control related to the sensor plate Sa, the control unit 180 of the present invention drives the body horizontal control unit 192 based on the sensed value at the horizontal sensor 182 as described above.

In the present invention, the horizontal control of the preliminary mounting part is performed by using the pair of sensor plates Sa and Sb and the sensors 138 and 139, substantially by turning off the horizontal control of the main frame using the horizontal sensor 182 . The horizontal control function of the body frame using the horizontal sensor 182 should be turned off, for example, before the start of the operation of the sensor plates Sa and Sb or the start of the preliminary horizontal control by this.

As described above, according to the present invention, it is understood that the basic technical idea is to control the cutting unit so that soil is not introduced during harvesting by using a pair of sensor plates and sensors provided under the cutting frame. 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 and their equivalents. .
