Description

Combine {COMBINE}

The present invention relates to a combine equipped with a grape tanks.

As such combiners, for example, those described in Patent Document 1 are already known. The combine has a threshing device for performing a threshing process on a cutting gap, and a grapefruit tank (grain tank) having a curved feeding opening (inlet) on the side wall and storing the curled grains. The combine also has a curling conveyor (lifting screw conveyor) for connecting a threshing device and a curling inlet, further transferring the curled curl from the threshing device to the curling inlet, and feeding the curled curling from the curling inlet. Further, a decompression sensor (rice sensor) is provided inside the curling tank of the combine. By this pressure-reducing sensor, the amount of accumulated curl in the grainy tank is detected.

Japanese Patent Laid-Open No. 9-308367

In the combine, when the grains are introduced into the grape tanks, the pressure in the grape tanks tends to rise because the air in the grape tanks is compressed. The increase in the internal pressure of such a grapefruit tank may cause the pressure sensor to react and erroneously detect the amount of stored grains in the grapefruit tank.

An object of the present invention is to provide a combine in which the inner pressure of the grape tanks is hard to rise when the grains are fed into the grape tanks.

A feature of the present invention is that,

A threshing device for performing a threshing process on the cut-

A graining tank in which a curved inlet is provided in a side wall,

And a curled conveying device which connects the curling device and the curling inlet and further transports the curled curling from the curling device to the curling inlet and feeds the curled curling from the curling inlet,

A pressure reducing sensor is installed inside the curling tank,

And a pressure-releasing opening communicating with the inside and the outside of the corrugated tank is provided at a position higher than the pressure-reducing sensor on the sidewall of the corrugated tank.

In the present invention, since the pressure-releasing opening communicating with the inside and the outside of the curling tank is provided, the air in the curling tank can escape from the pressure-releasing opening to the outside. As a result, when the grains are introduced into the grape tanks, the air in the grape tanks is less likely to be compressed. Therefore, the inner pressure of the grape tanks is unlikely to rise. In addition, the pressure release opening is provided at a position higher than the pressure reduction sensor in the side wall of the curling tank. Therefore, at least until the accumulated height of the curled grains in the grained tank reaches the height of the pressure-reducing sensor, the pressure-releasing opening is not buried by the curled-up so that the pressure can reliably be released.

Further, in the present invention,

It is preferable that the pressure-releasing opening is provided at a position higher than the lower end of the curling inlet.

According to this configuration, at least the pressure discharge opening is not buried by the curvature during the time until the accumulated height of the curled graft in the curled tank reaches the height of the grooved inlet, thereby reliably releasing the pressure.

Further, in the present invention,

The pressure releasing opening is preferably provided on the side wall of the curled tank provided with the curved inlet.

The grains fed into the grapefruit tank from the grapefruit inlet are liable to be deposited at positions spaced apart from the side wall provided with the grapefruit inlet. Therefore, the accumulation height of the curled grains in the grained tank is relatively low in the vicinity of the side wall provided with the grooved inlet. Therefore, according to this configuration, the pressure-releasing opening is hardly buried by the curvature, and the reliability of the pressure releasing is improved.

Further, in the present invention,

And an inner duct cover which opens in the lower direction while covering the pressure discharge openings and communicates the pressure discharge openings with the inside of the corrugated tank is provided in the inside of the corrugated tank.

According to this configuration, the inner duct cover covers the pressure-releasing opening, and communicates the pressure-releasing opening with the inside of the corrugated tank. This makes it possible to prevent the air in the grape tanks from escaping to the outside, but it is also difficult to cause the grains to protrude out of the grape tanks through the pressure discharge openings. In addition, since the inner duct cover is opened in the lower direction, it is difficult to allow the curved portion to enter into the inner duct cover, as compared with the case where the inner duct cover is opened upwardly or laterally. Further, even if the curved lid enters into the inner duct cover, the curled lid drops into the curled tank, so that the curled lid does not stay in the inner duct cover.

Further, in the present invention,

And an outer duct cover which is opened to the lower side and covers the pressure discharge openings and communicates the pressure discharge openings with the outside of the corrugated tank is provided outside the corrugated tank.

According to this configuration, the pressure discharge opening is covered by the external duct cover, and the pressure discharge opening communicates with the outside of the grapefruit tank. This makes it possible to allow the air in the grappling tank to escape to the outside, but it is also less likely that rain, snow, etc. will pass through the pressure discharge opening and enter the inside of the grape tanks. In addition, since the outer duct cover is opened downward, rain, snow, etc. are hard to enter into the outer duct cover as compared with the case where the outer duct cover is opened upwardly or laterally.

Further, in the present invention,

Wherein a plurality of the pressure-releasing openings are provided on side walls of the curling tanks,

It is preferable that the plurality of pressure-releasing openings are dispersedly disposed on one side region and the other side region with reference to a position where the curled-in injection port in the curling tank is installed as viewed from the top.

When a plurality of pressure-releasing openings are provided, if all the pressure-releasing openings are buried by the grooves, the air in the grouting tanks becomes difficult to escape to the outside. However, according to this configuration, even if the pressure-releasing opening disposed in the region on one side is buried by the curled-up, all of the pressure-releasing openings will not be buried unless the pressure-releasing opening disposed in the region on the other side is buried. Therefore, as compared with the case where all of the pressure-releasing openings are concentrically arranged in the region on one side, all of the pressure-releasing openings are prevented from being buried, and it is easy to avoid the situation that air in the corrugated tank is difficult to escape to the outside.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the drawings. In the following description, the direction of the arrow F shown in Figs. 1, 5 and 7 is referred to as "front", the direction of the arrow B as "backward", the direction of the arrow L as "left" Quot; right side ".

[Overall configuration of self-debulking combine]

As shown in Fig. 1, a pre-loading section 1 is provided in the front part of the base of the six-group pre-formatter demoulding combine, taking an example of the space between the packages. An operation section 3 is provided at the rear of the preload section 1. The operation section 3 is provided with a driver's seat 4. At the rear of the operation section 3, a grapefruit tank 6 is provided. On the left side of the grapefruit tank 6, a threshing device 5 is provided. Further, a drive engine 7 is provided on the lower side of the operation section 3. This decoupling combine is configured so that the power of the engine 7 is transmitted to each part.

As shown in Fig. 1, the grapefruit tank 6 has four side walls in the front, rear, left, and right sides. As shown in Fig. 2, a curved inlet 6a is provided in the left side wall 6A of the curling tank 6. As shown in Fig. As shown in Fig. 3, the threshing device 5 and the curling inlet 6a are connected by a curled-conveying device 10. The threshing device 5 and the grainy tank 6 are supported by the base frame 8.

The curtain cut by the pre-loading unit (1) is conveyed to the threshing unit (5). In the threshing device (5), the cut grooves are throttled. The curled curl is conveyed from the curling apparatus 5 to the curling inlet 6a by the screw-type curling conveyor 10 and is conveyed by the rotary blade 10a provided at the conveying end of the curling conveyor 10 , And is fed into the grapefruit tank 6 from the grapefruit inlet 6a. In this manner, the curled grains are stored in the grapefruit tank 6.

[Configuration relating to the pressure-reducing sensor and the pressure-releasing opening]

As shown in Fig. 2, three depressurization sensors 11a, 11b and 11c are provided in the interior of the grapefruit tank 6. As shown in Fig. The pressure sensors 11a and 11b are provided inside the left side wall 6A of the grapefruit tank 6. [ Further, the pressure-reducing sensor 11c is provided inside the rear side wall of the curling tank 6. Of these pressure sensors 11a, 11b and 11c, the pressure sensor 11a is installed at the highest position and the pressure sensor 11c is installed at the lowest position. The decompression sensor 11b is provided at the center between the decompression sensor 11a and the decompression sensor 11c in the height direction.

As shown in Fig. 1, the display section 12 is provided at a position visible from the driver's seat 4 in the operation section 3. [ The display unit 12 is configured to be able to display various conditions in the self-deactivating combine, including the curled-up amount in the curling tank 6.

When the pressure sensors 11a, 11b, and 11c receive the pressure of the curved sediment accumulated in the curling tank 6, the pressure sensors 11a, 11b, and 11c transmit an on signal to a control device (not shown) The control device controls the display contents on the display unit 12 based on the received ON signal. In this manner, the contents of the display on the display unit 12 correspond to the display contents corresponding to the amount of the curved storage in the curling tank 6. For example, in Fig. 2, the curvature in the curling tank 6 is deposited to a height between the pressure-reducing sensor 11a and the pressure-reducing sensor 11b, as indicated by a chain double-dashed line. In this state, the decompression sensor 11b and the decompression sensor 11c receive the pressure of the curved line, and thus transmit the ON signal to the control device. On the other hand, the pressure-reducing sensor 11a does not receive the on-signal to the control device since it is not under the pressure of the curvature. The control device then controls the control device so that the curvature is accumulated to the height between the pressure-reducing sensor 11a and the pressure-reducing sensor 11b based on the ON signal received from the pressure-reducing sensor 11b and the pressure- And controls display contents in the display unit 12. [

As shown in Fig. 2, at a position higher than the pressure-reducing sensors 11a, 11b, and 11c on the sidewall of the grapefruit tank 6, a pressure of a rectangular opening communicating the inside and the outside of the grapefruit tank 6 And a discharge opening 6b is provided. The pressure releasing opening 6b is provided at a position higher than the lower end of the curling inlet 6a. The pressure release openings 6b are provided on the side wall 6A on the left side of the four side walls of the front side, rear side, left side and right side of the corrugated tank 6 on which side the curved inlet 6a is provided .

As shown in Figs. 2 and 3, an inner duct cover 13 is provided in the interior of the grapefruit tank 6. As shown in Fig. The inner duct cover 13 is opened downward while covering the pressure discharge opening 6b so as to communicate the pressure discharge opening 6b and the inside of the cornification tank 6 with each other.

As shown in Fig. 3, an outer duct cover 14 is provided outside the grapefruit tank 6. As shown in Fig. The outer duct cover 14 is opened downward while covering the pressure discharge opening 6b to communicate the pressure discharge opening 6b with the outside of the grapefruit tank 6. [

As shown in Figs. 2 and 4, the inner duct cover 13 has three flange portions 13a. These flange portions 13a extend upwardly of the gas, forward of the gas, and rearward of the gas, respectively. The outer duct cover 14 also has three flange portions 14a. A left side wall 6A of the curling tank 6 is sandwiched between the flange portion 13a and the flange portion 14a. The flange portion 13a, the side wall 6A, and the flange portion 14a are jointed by the bolts 15. With this structure, the inner duct cover 13 and the outer duct cover 14 are provided on the left side wall 6A of the grapefruit tank 6.

According to the above configuration, even when the amount of threshing processing per unit time in the threshing device 5 is so large that a large amount of curved grains are fed into the grapefruit tank 6 at one time, the space in the grapefruit tank 6 is filled with the pressure- 6b. Therefore, it is possible to prevent the depressurization sensor 11a from reacting due to the rise of the internal pressure in the grapefruit tank 6 and erroneously detecting the stored amount of the grains in the grapefruit tank 6.

In the state where the remaining capacity of the grapefruit tank 6 is small, that is, in a state where the space is narrow, a relatively large amount of grains are stored in the grapefruit tank 6, (6) is likely to rise. Therefore, it is preferable to install the pressure discharge opening 6b at a relatively high position in order to reliably release the pressure even in a narrow space in the curling tank 6. [ In the above-described configuration, the pressure release openings 6b are provided at positions higher than the pressure reduction sensors 11a provided at the highest position among the three pressure sensors 11a, 11b, and 11c. Thereby, even when the accumulation height of the curled grains in the curling tank 6 reaches the height of the pressure-reducing sensor 11a and the space is relatively narrow, the pressure can reliably be released.

[First Alternative Embodiment]

The grapefruit tank 6 in the above embodiment is configured so that the grains can be stored until the entire inner space of the grapefruit tank 6 is filled with the grains. However, the present invention is not limited to this. 6 and 7 are views showing the internal structure of the curling tank 62 in this embodiment. In the present embodiment, a curved inlet 62a and a pressure relief opening 62b are provided in the left side wall 62A of the curling tank 62, as in the above embodiment. Unlike the above embodiment, a dividing section 16 is provided in the interior of the grapefruit tank 62. The inner space of the curling tank 62 is partitioned into a right upper space T and a space S other than the right upper space T by the partitioning portion 16. The configuration of the other portions in this embodiment is the same as that in the above embodiment.

In the above embodiment, the graining tank 6 is provided on the right side of the base. As a result, as the grains are stored in the grapefruit tank 6, the gravity center of the grains is further moved to a position biased to the right of the base. In contrast to the state where the center of gravity of the gas is located at the center of the gas, when the center of gravity of the gas is shifted to the right side of the gas, when the gas turns to the left during traveling, a large centrifugal force is generated. As a result, a large lateral force is required for turning, and accompanying this, the turning resistance becomes large. Therefore, it is necessary to set the exhaust amount of the engine 7 in the above embodiment to be relatively large in consideration of the turning resistance.

In this embodiment, as in the above-described embodiment, the grape tanks 62 are provided on the right side of the base. However, since the compartment 16 is provided in the compartments 62, it is only the space S that is filled with the curtain when the compartments are stored, and the space T is kept empty. Therefore, compared with the embodiment in which the partition 16 is not provided, the center of gravity of the gas is hardly deviated to the right side of the gas. In addition, the weight of the whole of the gas including the curvature in a state in which the curled grains are stored up to the maximum amount is smaller than in the above embodiment. Therefore, in this embodiment, as compared with the above-described embodiment, since the centrifugal force generated at the time of turning to the left becomes smaller, the lateral force required for turning also becomes smaller, and the turning resistance becomes smaller accordingly. As a result, the exhaust amount of the engine 7 can be set smaller than that of the above embodiment.

As shown in Fig. 7, the dividing section 16 is composed of two steel plates 161 and 162. As shown in Fig. The two steel plates 161 and 162 partially overlap each other and are fastened to each other by bolts 163. As shown in Fig. 6, a flange portion 161a extending to the right side of the base is formed at the upper end of the steel plate 161. As shown in Fig. A flange portion 162a is likewise formed at the upper end of the steel plate 162. [ The flange portion 161a is fastened to the upper wall of the grapefruit tank 62 by bolts 164. Similarly, the flange portion 162a is fastened to the upper wall of the grapefruit tank 62 by bolts 165. [ 6 and 7, a flange portion 161b extending in the rightward direction of the base is formed at the end of the steel plate 161 at the front of the base. A flange portion 162b is likewise formed at the end of the steel plate 162 at the rear of the base. The flange portion 161b is fastened to the front side wall of the grapefruit tank 62 by a bolt 166. [ Similarly, the flange portion 162b is fastened to the rear side wall of the grapefruit tank 62 by the bolt 167. [

As shown in Fig. 6, the curled-up tank 62 is constituted by a tank main body portion 62c, a lid portion 62d, and a bolt 62e. The lid portion 62d constitutes a part of the wall surface of the grape tanks 62. In addition, the entire remaining wall surface of the grape-shaped tank 62 is constituted by the tank main body portion 62c. The tank main body portion 62c is formed by welding a plurality of steel plates. A lower opening 62f is formed in the lower portion of the tank main body portion 62c. The lid portion 62d is fastened to the tank main body portion 62c by the bolt 62e in a state of closing the lower opening 62f.

With this configuration, an operator engaged in formation of the curling tank 62 can come out from the lower opening 62f after welding from the inside of the tank main body portion 62c. By closing the lower opening 62f with the lid portion 62d, the entire wall surface of the curling tank 62 is completed. In addition, the lid portion 62d is provided by the bolt 62e. Therefore, the user can remove the lid portion 62d by removing the bolt 62e. In this way, the user can enter the inside of the tank main body portion 62c from the lower opening 62f, so that the partition 16 can be accessed. As a result, the partition 16 can be attached and detached by the user. The user can select whether or not to use the dividing section 16 in consideration of the storage capacity of the grapefruit tank 62 required for his or her agricultural work to be carried out and the influence on the turning resistance due to the packaging state, .

As shown in Fig. 7, the partitioning portion 16 in the present embodiment is constituted by fastening two steel plates 161 and 162 with bolts 163. Therefore, when the two steel plates 161 and 162 are deformed by heat or the like, a gap may be generated between the steel plate 161 and the steel plate 162. In this case, it is assumed that a small amount of grains enters the space T through this gap.

Here, as shown in Fig. 6, a clearance C is formed between the lower end of the partition 16 and the side wall on the right side in the curling tank 62. As shown in Fig. Therefore, when a small amount of curved grains enters the space T, the curved drop falls into the space S through the gap C. Therefore, even when a small amount of curved grains can enter the space T, no curved grains are stored in the space T when the curved grains are stored in the grained tank 62, and only the space S is filled with the curved grains.
