The coupling mechanism 51 may be placed at a greater distance from the vehicle body 2 than the reverse pedal portion 4. That is, the coupling mechanism 51 may be disposed outside the vehicle body 2 compared to the reverse pedal portion 4.

The fixing member 52 is for coupling the reverse pedal unit 4 to the coupling mechanism 51. By being coupled to each of the reverse pedal portion 4 and the coupling mechanism 51, the fixing member 52 may function as a medium for coupling the reverse pedal portion 4 to the coupling mechanism 51. .

The insertion groove 53 may perform a guide function for moving the fixing member 52. That is, the fixing member 52 can move along the insertion groove 53. The position of the reverse pedal plate 40 can be changed by the reverse pedal unit 4 moving together with the fixing member 52. Accordingly, the agricultural work vehicle 1 according to the present invention can achieve the following effects.

First, the agricultural work vehicle (1) according to the present invention has a coupling function that couples the coupling mechanism (51) and the reverse pedal unit (4) by simply inserting the fixing member (52) into the insertion groove (53). and an alignment function to realign the reverse pedal plate 40.

Therefore, the agricultural work vehicle 1 according to the present invention has the advantage of not only increasing the ease of maintenance work through a simple structure, but also reducing manufacturing costs.

Second, in the agricultural work vehicle (1) according to the present invention, the insertion groove (53) is formed in the coupling mechanism (51), so that the positions of the fixing member (52) and the insertion groove (51) structure are relative to each other. It is implemented to be on the outside of the vehicle body 2. Accordingly, the agricultural work vehicle (1) according to the present invention does not require the worker to insert his/her hand deep inside in order to perform the task of moving the fixing member (52) along the insertion groove (51). do. Therefore, the agricultural work vehicle (1) according to the present invention not only increases the ease of moving the fixing member (52) along the insertion groove (51), but also increases the ease of operation of moving the fixing member (52) along the insertion groove (51), and also increases the ease of operation of moving the fixing member (52) along the insertion groove (51). , safety accidents that may occur due to structures, etc. can be prevented in advance.

The insertion groove 53 may be formed to penetrate the coupling mechanism 51. The insertion groove 53 may be dug into the coupling mechanism 51 to a predetermined depth and formed in a slide manner. The fixing member 52 inserted into the insertion groove 53 can be tightened by an operator to secure the reverse pedal unit 4 to the coupling mechanism 51. The fixing member 52 inserted into the insertion groove 53 can be moved along the insertion groove 53 without fixing the coupling mechanism 51 and the reverse pedal portion 4 to each other by being released by the operator. It can be a state. The worker realigns the forward pedal plate 30 and the reverse pedal plate 40 by loosening the fixing member 52 and moving it along the insertion groove 53, and tightening the fixing member 52 again. The reverse pedal unit (4) can be fixed to the coupling mechanism (51). Hereinafter, the process of changing the relative position between the forward pedal plate 30 and the reverse pedal plate 40 using the structure of the fixing member 52 and the insertion groove 53 will be described in detail with reference to the attached drawings.

That is, the reverse pedal unit 4 to which the fixing member 52 is coupled can rotate in the second rotation direction (CCW arrow direction) around the pedal shaft 6.

Next, when the reverse pedal unit 4 rotates in the second rotation direction (CCW arrow direction) about the pedal shaft 6, the reverse pedal plate 40 rotates upward (UD arrow direction). You can move. Accordingly, the reverse pedal plate 40 can be located at the same height as the forward pedal plate 30.

Next, the worker can tighten the fixing member 52 to fix the coupling mechanism 51 and the reverse pedal unit 4 again. Accordingly, the fixing member 52 is not moved arbitrarily.

Meanwhile, when the reverse pedal plate 40 is located in the upward direction (UD arrow direction) with respect to the forward pedal plate 30, the worker fixes the coupling mechanism 51 and the reverse pedal unit 4. The fixing member 52 can be released.

Next, as shown in FIG. 4, the operator can rotate the fixing member 52 in the first rotation direction (CW arrow direction) around the pedal shaft 6. That is, the reverse pedal unit 4 to which the fixing member 52 is coupled can rotate in the first rotation direction (CW arrow direction) around the pedal shaft 6.

Next, when the reverse pedal unit 4 rotates in the first rotational direction (CW arrow direction) around the pedal shaft 6, the reverse pedal plate 40 rotates in the downward direction (DD arrow direction). You can move. Accordingly, the reverse pedal plate 40 can be located at the same height as the forward pedal plate 30.

The protruding members 54 may be arranged to be spaced apart from each other along the direction in which the insertion groove 53 extends. Each of the protruding members 54 may be placed at a position corresponding to where the fixing member 52 can be located. Due to the protruding members 54, the distance that the fixing member 52 can move when inserted into the insertion groove 53 is reduced and can be placed at a preset position in the insertion groove 53. As a result, the position where the insert is inserted into the insertion groove 53 can be changed step by step. Accordingly, the agricultural work vehicle 1 according to the present invention can achieve the following effects.

First, the agricultural work vehicle 1 according to the present invention can further reduce the distance over which the fixing member 52 can arbitrarily move through the plurality of protruding members 54. Therefore, the agricultural work vehicle 1 according to the present invention has the effect of preventing safety accidents that may occur as the fixing member 52 moves arbitrarily during driving, thereby further increasing driving safety.

Second, in the agricultural work vehicle 1 according to the present invention, the protruding members 54 are arranged to be spaced apart from each other along the direction in which the insertion groove 53 extends, so that any one protruding member 54 is the fixing member. Even if it cannot withstand the impact applied from (52) and is damaged, another protruding member (54) can support the fixing member (52).

Third, the agricultural work vehicle 1 according to the present invention is implemented so that the fixing member 52 is inserted into the insertion groove 53 at a preset position. Therefore, the agricultural work vehicle 1 according to the present invention is implemented so that the fixing member 52 is supported on the protruding member 54 during the process of the worker tightening the fixing member 52 again, so that the fixing member 52 ) can further increase the ease of tightening work.

The protruding member 54 may be formed to have an outer surface of approximately the same shape as that of the fixing member 52 to increase the area for receiving the force transmitted from the fixing member 52. The protruding members 54 may be formed only on one side of the insertion groove 53 with respect to the fixing member 52. The protruding members 54 may be formed on both sides of the insertion groove 53 with respect to the fixing member 52. The protruding member 54 may be formed integrally with the coupling mechanism 51. The protruding member 54 may be made of an elastic material. In this case, the worker applies force to the protruding member 54 to elastically deform it without the need to remove the fixing member 52 from the insertion groove 53 and then insert it again into a different position in the insertion groove 53. By doing so, the fixing member 52 can be moved while inserted into the insertion groove 53.

Referring to Figures 5 and 6, the transmission unit 5 may include a first limit surface 55 and a second limit surface 56.

The first limiting surface 55 rotates in the first rotation direction (CW arrow direction) around the pedal shaft 6 while the fixing member 52 is inserted into the insertion groove 53. It is a limiting aspect. The first limiting surface 55 may be one surface of the coupling mechanism 51 surrounding the insertion groove 53.

Accordingly, in the agricultural work vehicle (1) according to the present invention, the reverse pedal unit (4) and the transmission unit (5) rotate too much in the first rotational direction (CW arrow direction). ) can be prevented from moving beyond the range of motion. Therefore, the agricultural work vehicle (1) according to the present invention prevents the reverse pedal unit (4) and the transmission unit (5) from being damaged, thereby preventing the reverse pedal unit (4) and the transmission unit (5) from being damaged. The lifespan can be further increased.

The second limiting surface 56 rotates in the second rotation direction (CCW arrow direction) around the pedal shaft 6 while the fixing member 52 is inserted into the insertion groove 53. It is a limiting aspect. The second limiting surface 56 may be one surface of the coupling mechanism 51 surrounding the insertion groove 53. The fixing member 52 rotates in the second rotation direction (CCW arrow direction), and when supported on the second limit surface 56, rotation in the second rotation direction (CCW arrow direction) may be restricted. there is.

Accordingly, in the agricultural work vehicle (1) according to the present invention, the reverse pedal unit (4) and the transmission unit (5) are rotated too much in the second rotation direction (CCW arrow direction) as the fixing member (52) rotates too much. ) can be prevented from moving beyond the range of motion. Therefore, the agricultural work vehicle (1) according to the present invention prevents the reverse pedal unit (4) and the transmission unit (5) from being damaged, thereby preventing the reverse pedal unit (4) and the transmission unit (5) from being damaged.

Referring to Figures 7 and 8, the reverse pedal unit 4 may include a reverse insertion groove 44.

The backward insertion groove 44 is for inserting the backward fixing member 43. The reverse insertion groove 44 may be formed in the second reverse pedal member 42. The reverse fixing member 43 coupled to the first reverse pedal member 41 may be coupled to the second reverse pedal member 42 by being inserted into the reverse insertion groove 44. The backward insertion groove 44 may perform a guide function for the movement of the backward fixing member 43. That is, the backward fixing member 43 can move along the backward insertion groove 44. In this case, the position of the reverse pedal plate 40 can be changed by the first reverse pedal member 41 moving together with the reverse fixing member 43.

Accordingly, the agricultural work vehicle (1) according to the present invention is capable of forming the first reverse pedal member (41) and the second reverse pedal member by simply inserting the reverse fixing member (43) into the reverse insertion groove (44). It is implemented to perform both a coupling function for combining (42) and an alignment function for realigning the reverse pedal plate (40). Accordingly, the agricultural work vehicle 1 according to the present invention can be implemented with a simple structure because there is no need to provide separate devices to perform each of the coupling function and the alignment function. Therefore, the agricultural work vehicle 1 according to the present invention has the advantage of not only increasing the ease of maintenance work through a simple structure, but also reducing manufacturing costs.

The reverse insertion groove 44 may be formed through the second reverse pedal member 42. The reverse insertion groove 44 may be dug into the second reverse pedal member 42 to a predetermined depth and formed in a slide manner. The reverse fixing member 43 inserted into the reverse insertion groove 44 can be tightened by an operator to fix the first reverse pedal member 41 to the second reverse pedal member 42. The backward fixing member 43 inserted into the backward insertion groove 44 is released by the operator, thereby allowing the backward insertion without fixing the first reverse pedal member 41 and the second reverse pedal member 42 to each other. It may be in a state where it can move along the groove 44. The worker realigns the reverse pedal plate 40 and the forward pedal plate 30 by loosening the reverse fixing member 43 and moving it along the reverse insertion groove 44, and then reinstalling the reverse fixing member 43. The first reverse pedal member 41 can be fixed to the second reverse pedal member 42 by tightening. Hereinafter, the process of changing the relative position between the reverse pedal plate 40 and the forward pedal plate 30 using the structure of the reverse fixing member 43 and the reverse insertion groove 44 will be described with reference to the attached drawings. Explain in detail.

First, when the reverse pedal plate 40 is located in the downward direction (DD arrow direction) with respect to the forward pedal plate 30, the worker moves the first reverse pedal member 41 to the second reverse pedal member ( The backward fixing member 43 fixed to 42) can be loosened.

Next, as shown in FIG. 8, the operator may rotate the backward fixing member 43 in the second rotation direction (CCW arrow direction) around the backward shaft member 45. That is, the first reverse pedal member 41 to which the backward fixing member 43 is coupled can rotate in the second rotation direction (CCW arrow direction) around the reverse shaft member 45.

Next, when the first reverse pedal member 41 rotates in the second rotation direction (CCW arrow direction) around the reverse shaft member 45, the reverse pedal plate 40 rotates in the upward direction (UD arrow direction). direction) can be moved. Accordingly, the reverse pedal plate 40 can be located at the same height as the forward pedal plate 30.

Next, the worker can tighten the reverse fixing member 43 to fix the first reverse pedal member 41 to the second reverse pedal member 42 again. Accordingly, the backward fixing member 43 is not moved arbitrarily.

Meanwhile, when the reverse pedal plate 40 is located in the upward direction (UD arrow direction) with respect to the forward pedal plate 30, the worker moves the first reverse pedal member 41 to the second reverse pedal member ( The backward fixing member 43 fixed to 42) can be loosened.

Next, the operator may rotate the backward fixing member 43 in the first rotational direction (CW arrow direction) around the backward shaft member 45. That is, the first reverse pedal member 41 to which the backward fixing member 43 is coupled can rotate in the first rotation direction (CW arrow direction) around the reverse shaft member 45.

Next, when the first reverse pedal member 41 rotates in the first rotational direction (CW arrow direction) around the reverse shaft member 45, the reverse pedal plate 40 rotates in the downward direction (DD arrow direction). direction) can be moved. Accordingly, the reverse pedal plate 40 can be located at the same height as the forward pedal plate 30.

Next, the worker can tighten the reverse fixing member 43 to fix the first reverse pedal member 41 to the second reverse pedal member 42 again. Accordingly, the backward fixing member 43 is not moved arbitrarily.

Here, the agricultural work vehicle 1 according to the present invention may include various embodiments depending on the form in which the reverse insertion groove 44 is formed. Hereinafter, embodiments of the form in which the reverse insertion groove 44 is formed in the agricultural work vehicle 1 according to the present invention will be sequentially described with reference to the attached drawings.

First, referring to FIGS. 7 and 8, the backward insertion groove 44 may be formed in an arc shape centered on the backward shaft member 45. When the backward fixing member 43 is coupled to the first reverse pedal member 41, it rotates around the backward shaft member 45, so the backward insertion groove 44 follows an arc trajectory. It may be formed in a form that matches the movement path of the rotating backward fixing member 43.

Accordingly, the agricultural work vehicle (1) according to the present invention has the fixing member (43) attached to the wall forming the reverse insertion groove (44) while the reverse fixing member (43) moves along the reverse insertion groove (44). (53) is implemented so that no jamming is formed. Therefore, when preparing for an embodiment in which the fixing member 53 forms a catch, the agricultural work vehicle (1) according to the present invention has the fixing member (53) inserted into the reverse insertion groove (44). Since it can be moved, the ease of moving the fixing member 53 can be further increased.

Although not shown, the reverse pedal unit 4 may include a reverse protruding member.

The backward protruding member limits the distance that the backward fixing member 43 can move when inserted into the backward insertion groove 44. The backward protruding member may protrude from the second reverse pedal member 42 toward the backward insertion groove 44. When the backward fixing member 43 moves while inserted into the backward insertion groove 44, the backward protruding member is disposed on the movement path of the backward fixing member 43 and moves the backward fixing member 43. may form a jam.

Accordingly, the agricultural work vehicle (1) according to the present invention is driven in a state in which the reverse fixing member (43) is tightened and the first reverse pedal member (41) is fixed to the first reverse pedal member (41). In this case, the distance that the reverse fixing member 43 can arbitrarily move may be reduced due to vibration and shock that occur during driving. Therefore, the agricultural work vehicle (1) according to the present invention is driven by preventing safety accidents in advance by reducing the degree to which the height of the forward pedal plate (30) changes due to the reverse fixing member (43) arbitrarily moving during driving. It has the advantage of increasing safety.

Although not shown, the reverse pedal unit 4 may include a plurality of reverse protruding members.

The backward protruding members may be arranged to be spaced apart from each other along the direction in which the backward insertion groove 44 extends. Each of the backward protruding members may be disposed at a position corresponding to a position where the backward fixing member 43 can be located. Due to the backward protruding members, the distance that the backward fixing member 43 can move when inserted into the backward insertion groove 44 is reduced, and it can be placed at a preset position in the backward insertion groove 44. This allows the insertion position into the backward insertion groove 44 to be changed step by step. Accordingly, the agricultural work vehicle 1 according to the present invention can achieve the following effects.

First, the agricultural work vehicle 1 according to the present invention can further reduce the distance over which the backward fixing member 43 can arbitrarily move through the plurality of backward protruding members. Therefore, the agricultural work vehicle 1 according to the present invention has the effect of preventing safety accidents that may occur as the reverse fixing member 43 arbitrarily moves during driving, thereby further increasing driving safety.

Second, in the agricultural work vehicle (1) according to the present invention, the backward protruding members are arranged to be spaced apart from each other along the direction in which the backward insertion groove (44) extends, so that one of the backward protruding members is separated from the backward fixing member (43). Even if it cannot withstand the applied impact and is damaged, other backward protruding members can support the backward fixing member 43.

Third, the agricultural work vehicle (1) according to the present invention is implemented so that the reverse fixing member (43) is inserted into the reverse insertion groove (44) at a preset position. Accordingly, the agricultural work vehicle 1 according to the present invention is implemented so that the backward fixing member 43 is supported on the backward protruding member during the process of the worker tightening the backward fixing member 43 again, so that the backward fixing member ( 43) can further increase the ease of tightening work.

The backward protruding member may be formed to have an outer surface of approximately the same shape as that of the backward fixing member 43 to increase the area for accommodating the force transmitted from the backward fixing member 43. The backward protruding members may be formed only on one side of the backward insertion groove 44 with respect to the backward fixing member 43. The backward protruding members may be formed on both sides of the backward insertion groove 44 with respect to the backward fixing member 43. The backward protruding member may be formed integrally with the second reverse pedal member 42. The backward protruding member may be formed of an elastic material. In this case, the worker applies force to the backward protruding member to make it elastic without the need to remove the backward fixing member 43 from the backward insertion groove 44 and then insert it again into a different position in the backward insertion groove 44. By deforming, the backward fixing member 43 can be moved while inserted into the backward insertion groove 44.

<Second Modified Embodiment>

Referring to Figures 9 and 10, the reverse pedal unit 4 may include a plurality of each of the reverse fixing member 43 and the reverse insertion groove 44. Here, plural means two or more, but for convenience of explanation, it is assumed that the reverse pedal unit (4) includes two each of the reverse fixing member (43) and the reverse insertion groove (44). It is explained as follows. In addition, the backward fixing members 43 are named as the first backward fixing member 431 and the second backward fixing member 432, respectively, and the backward insertion grooves 44 are respectively called the first backward insertion groove 441 and It is named the second reverse insertion groove (442).

The first reverse fixing member 431 and the second reverse fixing member 432 are used to couple the first reverse pedal member 41 to the second reverse pedal member 42 at positions spaced apart from each other. The first backward fixing member 431 and the second backward fixing member 432 move forward and backward (Y-axis direction) parallel to each of the forward direction (FD arrow direction) and the backward direction (BD arrow direction). They can be placed at locations spaced apart from each other based on the standard. Accordingly, the agricultural work vehicle (1) according to the present invention provides a fixing force so that the first reverse pedal member (41) is fixed to the second reverse pedal member (42) through a plurality of reverse fixing members (43). As implemented, in contrast to an embodiment in which only a single reverse fixing member 43 provides fixing force, when a large pedal force is suddenly applied to the first reverse pedal member 41, the first reverse pedal member 41 ) has the advantage of being able to reduce the degree to which it randomly moves to a position misaligned with respect to the second reverse pedal member 42.

Referring to FIGS. 9 and 10, when the reverse pedal unit 4 includes a plurality of each of the reverse fixing member 43 and the reverse insertion groove 44, the first reverse pedal member 41 has the It can be rotatably coupled to the second reverse pedal member 42 about the pedal shaft 6. As the first reverse pedal member 41 rotates in the first rotational direction (CW arrow direction) about the pedal shaft 6, the reverse pedal plate 40 is rotated in the downward direction (DD arrow direction). It can be moved to . As the first reverse pedal member 41 rotates in the second rotation direction (CCW arrow direction) about the pedal shaft 6, the reverse pedal plate 40 moves upward (UD arrow direction). It can be moved to .

Referring to Figures 9 and 10, the first backward insertion groove 441 and the second backward insertion groove 442 are formed at positions spaced apart from each other. The first backward fixing member 431 may be inserted into the first backward insertion groove 441. In this case, the first backward fixing member 431 can move along the first backward insertion groove 441. The second backward fixing member 432 may be inserted into the second backward insertion groove 442. In this case, the second backward fixing member 432 can move along the second backward insertion groove 442. Therefore, each of the first backward insertion groove 441 and the second backward insertion groove 442 corresponds to the position where the first backward fixing member 431 and the second backward fixing member 432 are disposed. can be formed in For example, when the first backward fixing member 431 and the second backward fixing member 432 are disposed at positions spaced apart from each other based on the front-back direction (Y-axis direction), the first backward insertion groove 441 ) and the second backward insertion groove 442 may be formed at positions spaced apart from each other based on the front-back direction (Y-axis direction).

Hereinafter, the process of changing the relative position between the reverse pedal plate 40 and the forward pedal plate 30 using the plurality of reverse fixing members 43 and the plurality of reverse insertion grooves 44 is illustrated in the attached drawing. This will be described in detail with reference to .

First, when the reverse pedal plate 40 is located in the downward direction (DD arrow direction) with respect to the forward pedal plate 30, the worker moves the first reverse pedal member 41 to the second reverse pedal member ( The first backward fixing member 431 and the second backward fixing member 432 fixed to 42) can be released.

Next, as shown in FIG. 10, the worker moves the first backward fixing member 431 and the second backward fixing member 432 in the second rotation direction (CCW arrow direction) around the pedal shaft 6. ) can be rotated. That is, the first reverse pedal member 41, in which the first reverse fixing member 431 and the second reverse fixing member 432 are combined, rotates in the second rotation direction (CCW) around the pedal shaft 6. It can rotate in the direction of the arrow).

Next, when the first reverse pedal member 41 rotates in the second rotation direction (CCW arrow direction) about the pedal shaft 6, the reverse pedal plate 40 rotates in the upward direction (UD arrow direction). ) can be moved to . Accordingly, the reverse pedal plate 40 and the forward pedal plate 30 can be positioned at the same height.

Next, the worker can fix the first reverse pedal member 41 to the second reverse pedal member 42 again by tightening each of the first reverse fixing member 431 and the second reverse fixing member 432. there is. Accordingly, the first backward fixing member 431 and the second backward fixing member 432 are not moved arbitrarily.

Meanwhile, when the reverse pedal plate 40 is located in the upward direction (UD arrow direction) with respect to the forward pedal plate 30, the worker moves the first reverse pedal member 41 to the second reverse pedal member ( The first backward fixing member 431 and the second backward fixing member 432 fixed to 42) can be released.

Next, the worker may rotate the first backward fixing member 431 and the second backward fixing member 432 in the first rotational direction (CW arrow direction) around the pedal shaft 6. That is, the first reverse pedal member 41, to which each of the first reverse fixing member 431 and the second reverse fixing member 432 are coupled, is centered on the pedal shaft 6 in the first rotation direction ( It can rotate in the CW arrow direction).

Next, when the first reverse pedal member 41 rotates in the first rotational direction (CW arrow direction) about the pedal shaft 6, the reverse pedal plate 40 rotates in the downward direction (DD arrow direction). ) can be moved to . Accordingly, the reverse pedal plate 40 can be located at the same height as the forward pedal plate 30.

Next, the worker can fix the first reverse pedal member 41 to the second reverse pedal member 42 again by tightening each of the first reverse fixing member 431 and the second reverse fixing member 432. there is. Accordingly, the backward fixing member 43 is not moved arbitrarily.

Referring to FIGS. 9 and 10, each of the first reverse insertion groove 441 and the second reverse insertion groove 442 may be formed in an arc shape centered on the pedal shaft 6. . When each of the first reverse fixing member 431 and the second reverse fixing member 432 is coupled to the first reverse pedal member 41, it rotates around the pedal shaft 6, so that the first reverse fixing member 432 rotates around the pedal shaft 6. Each of the backward insertion groove 441 and the second backward insertion groove 442 coincides with the movement path of the first backward fixing member 431 and the second backward fixing member 432, which rotate in an arc. It can be formed into a shape.

Referring to Figures 9 and 10, when the first reverse insertion groove 441 and the second reverse insertion groove 442 are formed in an arc shape centered on the pedal shaft 6, the It can be formed to have the same angle when centered on the pedal axis 6. Accordingly, in the agricultural work vehicle (1) according to the present invention, the first reverse fixing member 431 and the second reverse fixing member 432 each have the same rotational angle range about the pedal shaft 6. It is implemented to do so. Therefore, in the agricultural work vehicle (1) according to the present invention, the first reverse fixing member 431 and the second reverse fixing member 432 rotate around the pedal shaft 6 and the first reverse insertion groove Since it is supported together by the wall forming (441) and the wall forming the second reverse insertion groove 442, the first reverse pedal member 41 is within an angle range within which the pedal shaft 6 can be rotated. This can further reduce the possibility of rotation occurring.

Although not shown, when the reverse pedal unit 4 includes a plurality of the reverse fixing members 43 and a plurality of the reverse insertion grooves 44, at least one of the reverse insertion grooves 44 has the reverse insertion groove 44. At least one backward protruding member may be formed. Since the characteristics of the backward protruding member are the same as described above, they are omitted hereinafter.
