Description

The present invention relates to a bonnet mounting structure for a traveling vehicle such as a transplanter.

Conventionally, a bonnet that covers the engine mounted on the traveling machine body of the transplanter is provided slidably in the front-rear direction with respect to a floor step on which a worker can walk, and is projected below the front part of the hem of the bonnet body. A hook-shaped engaging claw member that is engaged with the front side of the floor step in a fitted state and integrally protrudes from the inner wall (inner surface side) on the upper side of the hem rear end side. A bonnet mounting structure that is mounted on the front end side of a rear panel via a claw is already known. (For example, refer to Patent Document 1).

Japanese Patent No. 6008720

In the bonnet mounting structure disclosed in Patent Document 1, when the bonnet is pushed backward along the guide groove, the protrusion and the claw can engage with the floor step and the rear panel, respectively, so that the bonnet can be efficiently assembled to the machine body. There is an advantage that can be.
However, the claw integrally projecting on the inner wall of the rear end side of the bonnet is a connection method in which the rear panel front end introduced into the recess by the guide surface is simply inserted into the groove and fitted, and the rear panel front end Since the guide surface for introducing the portion is formed by a short inward slope, it has a structure that does not elastically press the front end portion of the rear panel fitted in the concave portion, and is simply pushed into the concave portion. The rear panel has a problem that it is apt to be accompanied by chatter vibration and vibration noise due to engine or machine body vibration.
In addition, when the hood of the bonnet is flexed and deformed outward, or the front end of the rear panel is flexed and deformed inward when the bonnet is assembled by synthetic resin molding. In addition, as the bonnet is pushed in, the claws will be located outside the front end of the rear panel (joining idle position), so when the operator overlooks this and performs a random pushing operation, There is a problem that a claw protruding sharply from the inner wall due to the slanted surface and having a short shape slidably contacts the outer wall (outer surface) of the front end portion of the rear panel to cause scratches.

In order to solve the above-mentioned problems, the present invention firstly provides a bonnet 16 that covers an engine 29 mounted in front of the traveling vehicle body 5, with a lower portion of the bonnet hem 16b with respect to a floor step 26 on the side of the driving operation unit 17. A rear panel member 22 that is slidably engaged in the front-rear direction and is installed on the machine body side in a holding groove 36a formed by a claw piece 36 that projects inward from the inner wall of the rear end side 16h of the hood 16b. In the bonnet mounting structure of a traveling vehicle in which the front end portion 22a of
The claw piece 36 has a tip length that projects from the rear end side 16h of the bonnet hem 16b so that it can be pressed by a finger along the sliding direction from the claw base 36b side where the groove bottom 36e of the holding groove 36a is formed. A flat plate-shaped member having flexibility and elastic force is formed laterally, and the front end portion 22a of the rear panel member 22 is sandwiched between the flat plate-shaped member at a portion facing the rear end side 16h in the sandwiching groove 36a. The holding surface 36d is provided, and a guide portion 36c for guiding the introduction into the holding groove 36a is provided by elastically abutting the tip end portion of the holding surface with the inner wall of the rear panel member 22. ..
Secondly, the left and right width of the holding groove 36a is made into a slit shape smaller than the thickness of the front end portion 22a of the rear panel member 22, and the groove bottom 36e is about several times longer than the groove length forming the holding surface 36d. It is characterized in that it is provided at a depth position having a depth.
Thirdly, the convex projection 37 is formed on the inner surface side along the longitudinal direction of the claw piece 36.

According to the invention of claim 1, the bonnet is slidably engaged in the front and rear direction with respect to the floor step, and the bonnet is provided so as to project inward from the inner wall of the rear end side of the bonnet hem. In a bonnet mounting structure of a traveling vehicle in which a front end portion of a rear panel member installed on the machine body is inserted and connected to a holding groove formed by a claw piece, the claw piece is a claw in which a groove bottom of the holding groove is formed. With a tip length protruding from the rear end side of the bonnet skirt along the sliding direction from the base side so that it can be pushed by a finger, a flat plate member having flexibility and elastic force and formed in a horizontally long shape, The flat plate-like member is provided with a holding surface for holding the front end portion of the rear panel member at a portion facing the rear end side in the holding groove, and a claw tip portion continuous with this is elastically abutted on the inner wall of the rear panel member. By providing a guide portion for guiding the introduction into the holding groove,
When the bonnet is pushed and moved to connect to the rear panel member, the claw piece elastically clamps and fixes the front end portion of the rear panel member introduced and guided by the guide portion in the clamping groove by the clamping surface and the guide portion of the rear panel member. Since it is pushed toward the inner wall, it is possible to efficiently assemble the claw pieces and the panel member while preventing chatter vibration and rattling.
Even when the rear panel member is in the inclining and deforming posture, the long and moderately formed claw piece is formed by a finger pushing operation on the long protruding guide portion side during assembly. By pushing the front end portion into the inner wall side of the rear panel member, the pushing operation can be performed without any hindrance, and the work of attaching the bonnet that prevents damage to the outer wall side of the rear panel member can be performed smoothly.
According to the invention of claim 2, the holding groove has a left-right width that is a slit shape smaller than the thickness of the front end portion of the rear panel member, and the groove bottom is about several times the groove length that forms the holding surface. By providing it at the depth position that has the groove length,
The claw piece 36 having a holding groove 36a having a left-right width smaller than the thickness of the front end portion 22a of the rear panel member 22 flexibly resists the elastic force of the guide portion 36c and the holding surface 36d to expand the holding groove 36a. In addition, the rear panel member introduced into the holding groove 36a can be elastically and securely fixed and held by an appropriate holding biasing force.
Further, the claw piece 36 formed by providing the groove bottom 36e of the sandwiching groove 36a on the innermost side of the sandwiching surface 36d is manufactured by appropriately providing flexibility and elasticity due to the longer claw piece length. In addition to being easy, elastic clamping can be stably performed even when the clamping position of the rear panel member is changed.
According to the invention of claim 3, by forming the ridge projection on the inner surface side along the longitudinal direction of the claw piece,
Since the ridge projection has toughness and elastic force in the bending direction and can enhance the durability and the gripping force of the claw piece as desired, when the finger pressing operation is repeatedly performed, it is easy to bend and resist bending. Even while having durability, it is possible to smoothly guide the introduction of the rear panel member into the holding groove, and to hold and fix the holding surface side stably for a long period of time.

The planting work machine 9 has a frame portion 10 supported by a link mechanism 7 so as to be rotatable (rollable) around an axis in the front-rear direction, which is the traveling direction of the traveling machine body 5, and has a horizontal control motor (not shown). Also, the inclination sensor makes it possible to maintain a horizontal posture even in a field having a left-right inclination.

The frame part 10 supports the seedling placing table 11 so as to be able to reciprocate left and right in a tilted posture of front high rear low. On the seedling placing table 11, the mat seedlings placed on the placing surface are lowered. A vertical feed mechanism 12 for carrying is installed. A planting part 13 is integrally extended behind the frame part 10. When the transplanting rod 15 of the planting part 13 rotates, the planting part 13 is placed on the placement surface and conveyed to the lower end. It is possible to scrape one seedling from the mat seedlings that have been cut and continuously transplant it to the field.

In the traveling machine body 5, a bonnet 16 in which an engine and the like are housed is arranged in a front part, and a driving operation part 17 in which a worker operates the transplanter 1 is arranged in a rear part.
The driving operation unit 17 includes a driving seat 19 on which an operator sits, a steering handle 20 for turning the traveling machine body 5, a main speed change lever 21 for switching between forward and reverse movements, and the like. The front part of the feet when seated in the driver's seat 19 is covered with a rear panel 22.

Next, the bonnet 16 and the bonnet mounting structure will be described with reference to FIGS.
As shown in FIGS. 2 to 4, front steps 23 are arranged on the left and right sides of the bonnet 16, and a main step 25 constituting the floor surface of the driver's seat 19 is arranged behind the front steps 23. The front step 23 and the main step 25 are continuously formed, and are integrally configured as a floor step 26 for an operator to walk on the traveling machine body 5.

The bonnet 16 has a main body portion 16a which covers the engine room and is formed to be constricted toward the front, and a hem portion 16b which laterally extends from the upper surface portion of the main body portion 16a toward the lower ends on both sides. There is. As shown in FIGS. 3 and 9, a cover mounting hole 27a for mounting a front cover 27 on which a headlight, a horn, etc. are mounted is formed at the front end of the main body 16a.
The front cover 27 attached to the cover attachment hole 27a has an attachment unit 28a for the center mascot 28, which serves as an index during traveling, on the back side surface thereof.

Further, a notch 16c is provided at the upper rear end of the main body portion 16a for jointly fixing the knob panel 24 (see FIG. 2) to an operation panel 38 described later (FIG. 3). The hem portion 16b increases the area of the front step 23 in combination with the main body portion 16a being formed in a narrowed shape toward the front, thereby improving the operator's ease of getting on and off from the front. ing.

Further, as shown in FIGS. 4 and 10, inside the bonnet 16, an engine 29 and a mission case for shifting the power of the engine 29 and distributing the power to the front wheels 2, the rear wheels 3 and the planting work machine 9, etc. Are arranged. A fuel tank 34 is arranged above and behind the engine 29 and over the upper front portion of the rear panel 22, and an operation panel 38 as a rear panel member is provided on the rear side of the fuel tank 34 by an arbitrary attaching means on the machine body side. It is installed in support.

As shown in FIGS. 4 to 6, the floor step 26 has a notch 30 whose front is opened and which accommodates the engine 29 (FIG. 5). Horizontally parallel guide grooves (guide portions) 31 are formed along the edge 30a.
A hole 32 is formed in the lower portion of the left and right guide grooves 31 on the front end surface of the floor step 26, and the hole 32 is fitted in the lower front portion of the hem portion 16b of the bonnet 16. The protrusion 33 is integrally formed.

The rear portion of the guide groove 31 is a ∪-shaped groove (groove) 35 that is formed in a ∪-shaped shape in a front view by the rising surface 30b protruding upward from the edge 30a of the cutout portion 30. (Fig. 5)
Rail portions 16d formed in parallel with the left and right lower surfaces of the skirt portion 16b are configured to be fitted into the ∪-shaped groove 35 from the front of the traveling machine body 5.
The ∪-shaped groove 35 is formed so as to become narrower from the front toward the rear, and the rail portion 16d is locked at the rear end portion of the ∪-shaped groove 35. Securely fixes and prevents chattering noise that tends to accompany running or idling.

Next, the configuration and usage of the bonnet mounting structure and the claw piece 36 according to the present invention will be described with reference to FIGS. First, the bonnet 16 is provided with a claw piece 36 serving as a claw member of a bonnet mounting structure via a holding groove 36a on the inside (inner wall) of the rear end sides 16h of the left and right rear portions of the main body having a downward U-shape. And a flat plate-shaped member having an elastic force and formed in a horizontally long shaft shape so that it can be integrally formed at the time of molding a synthetic resin.

That is, as shown in FIGS. 7 and 8, the claw piece 36 is a flat plate extending from the claw base 36b side where the groove bottom (groove valley) 36e of the holding groove 36a is formed to the claw tip along the sliding direction of the bonnet 16. The member facing the rear end side 16h in the holding groove 36a is formed as a holding surface 36d that elastically holds and biases the front end 22a of the rear panel member 22 and is connected to the rear surface from the holding groove 36a. The portion extending toward the side is a guide portion 36c that elastically abuts on the inner surface side of the rear panel member 22 and guides it so that it can slide.

When the bonnet 16 including the claw pieces 36 is slidably pushed from the front to the rear, the left and right claw pieces that project long rearward with respect to the front end portion (front end side) 22a of the rear panel 22. When the guide portion 36c of 36 is inserted into the inner surface of each front end portion 22a of the rear panel 22, the bonnet 16 is efficiently assembled and fixed by a one-touch operation according to a usage mode described later while performing an elastic slide guide action. I am trying to get it done quickly.

The claw piece 36 in the illustrated example has a groove depth of the sandwiching groove 36a formed from the end of the rear end side 16h toward the front at the inner wall position in the middle of or slightly higher than the rear end side height of the hem 16b. Is a slit-like groove suitable for facilitating the mold release at the time of synthetic resin molding, while the claw piece 36 urges the front end portion 22a of the rear panel 22 by a predetermined clamping force to fix and support the front end portion 22a. The groove depth is.
The total length of the claw piece from the claw base portion 36b to the tip of the claw (rear end portion) is about 200 mm, the guide length protruding from the rear end side 16h is about 50 mm, and the claw piece width is about 40 mm. The thickness of one tip side is about 5 mm.

Further, the width of the holding groove 36a formed between the inner wall of the hem portion 16b and the claw piece 36 is a slit-like groove which is smaller than the thickness of the front end portion 22a of the rear panel 22 (panel holding thickness). The groove bottom 36e is preferably formed at a groove depth position which is several times the groove length of the holding surface 36d.
With this, the claw piece 36 can be easily manufactured by increasing the total length of the flat plate-like member to have flexibility and elastic force, and resist the elastic force through the introduction action of the guide portion 36c. The front end 22a of the rear panel 22 that is pushed into the expanded sandwiching groove 36a is elastically fixed by a proper clamping force by clamping the wedge by the guide portion 36c and the inner wall of the rear end side 16h. The connection can be secured.

Further, according to the connection mode of the both, since the claw piece 36 is provided at the height position of the rear end side 16h, there is a processing error in the front-back direction, a bending deformation in the left-right direction, etc. at the sandwiching position. Even in such a case, by elastically connecting the wedges, elastic clamping can be stably performed even when the clamping position of the rear panel member 22 or the operation panel 38 is changed, and positioning in the front-rear, left-right direction is possible. It can also be clamped without any trouble because it has anti-vibration properties.
Further, since the bonnet 16 is fixedly mounted on the upper and lower sides, the middle portion of the rear end side 16h is joined to the fuselage side via the rear panel 22 at the above-mentioned height position, so that the chatter vibration and the like due to the vibration of the fuselage is prevented and stable. There are advantages such as various attachments and fixations.

The bonnet 16 having the claw pieces 36 having the above-described structure can be manufactured in a simple and inexpensive die-molding structure that does not require complicated and elaborate machining for the molding die during the synthetic resin molding, thus improving the production efficiency. There are also features such as cost reduction and cost reduction.
In other words, the forming die in this case is a slide plate that can slide in the pulling direction with a strip-shaped piece (not shown) sufficient to form the groove shape and the space shown in FIG. With a simple structure in which it is attached via a die or a mounting means such as a screw stopper, it is possible to efficiently and inexpensively manufacture without significantly changing the existing synthetic resin molding die or process.

The shape and configuration of the sandwiching groove 36a is not limited to the illustrated example. For example, when the groove bottom 36e is formed as a rounded surface having a slightly large left and right width as shown by a two-dot chain line in FIG. Since the claw piece 36 can be easily spread greatly from the base side, the connection can be made smoothly by the wedge driving mode corresponding to the thick rear panel 22.
Further, the tip corners of the claw pieces 36 protruding in a zigzag shape when viewed from the side are formed into rounded surfaces having a large radius so as to smoothly contact the inner wall and the outer wall of the rear panel 22.
As a result, the claw piece 36 has a smooth wide wrinkle shape with no edge portion on the inner surface side (non-sandwich surface side) of the claw piece 36, so that even when the inner surface side of the claw is at the joining idle position of the rear panel 22, a smooth contact is achieved. Thus, it is possible to prevent the outer wall from being scratched.

Further, as shown in FIG. 8D, it is desirable that the claw piece 36 is provided with a plurality of convex projections 37 extending in the longitudinal direction on the inner surface side (non-holding surface side) of the claw. In this case, the meat of the main body of the claw piece is provided. The thickness is made as thin as possible to increase the flexibility while reducing the synthetic resin material and reducing the weight, and the ridge projection 37 balances the toughness and the elastic force in the bending direction to enhance the clamping force and the durability. be able to.
The claw piece 36 thus formed can be thinned to the tip of the claw while making the claw base 36b side forming the groove bottom 36e of the slit-shaped holding groove 36a thick so as to have a claw strength, and thus the claw tip side. It is possible to easily bend the shaft-shaped guide portion 36c by an inward pushing operation with a finger, to smoothly guide the introduction to the rear panel 22, and to hold and fix the thick-walled holding surface 36d side in the holding groove 36a. Create advantages such as stable operation over a long period of time.

Next, a bonnet mounting mode of the bonnet mounting structure configured as described above will be described with reference to FIGS. 5, 7, 8 and 10.
When the operator slides the bonnet 16 from the front of the machine to the rear side and attaches it to the rear panel 22 side, first, the rail portions 16d formed under the left and right hem portions 16b are formed on the floor step 26. The guide grooves 31 on the left and right sides are positioned and engaged with each other.

Next, the bonnet 16 is pushed and slid into the guide groove 31, while the rail portion 16d is engaged with the ∪-shaped groove 35 in the rear portion. At this time, the protruding portion 33 provided on the hem portion 16b of the bonnet 16 is fitted into the hole 32 of the floor step 26, and the left and right claw pieces 36 have the guide portions 36c protruding rearward from the left and right sides of the rear panel 22. In order to enter the inside of the front end portion 22a, the holding groove 36a is guided and guided to the front end portion 22a side by the outer surface of the claw piece 36, and is pushed into the holding groove 36a as shown in FIG. 8A. ..

Next, after confirming the positioning of each place, the operator performs the final pushing operation of the bonnet 16 to complete the engagement between the rail portion 16d and the ∪-shaped groove 35 and the engagement between the protruding portion 33 and the hole 32. At the same time, the claw piece 36 and the front end portion 22a are clamped and fixed.
Next, in the assembled and set state of the bonnet 16, the knob bolt 24 is inserted and fastened into the notch 16c formed in the upper end of the bonnet 16, and the operation panel 38 and the bonnet 16 are fastened together, whereby the bonnet 16 slides and moves. The bonnet installation work that made the

On the other hand, when the bonnet 16 is removed, the bonnet 16 can be removed by performing the operation in the reverse order of the bonnet mounting operation.
That is, the bonnet 16 from which the fastening of the knob bolts 24 has been released in this detaching work is fitted with the lower step 26 on the lower side of the hem portion 16b by a one-touch operation of grasping the main body portion 2a with both hands and simply pulling it back to the front. Can be initially released, and the connection between the upper side of the rear end side 16h and the mounting member on the body side such as the rear panel 22 or the operation panel 38 by sandwiching and fixing can also be gradually released by the removing work mode described later. Since the hood 16 can be detached, the bonnet 16 that prevents damage to the rear panel 22 and the like can be easily attached and detached, and maintenance work of the engine room can be performed efficiently.

Next, one mode of a connection example between the claw pieces 36 of the bonnet 16 and the rear panel 22 will be described in detail with reference to FIG. First, when the hem 16b is connected to the front end 22a of the rear panel 22 when the bonnet 16 is assembled, for example, when the hem 16b of the bonnet 16 is flexed and deformed outward, or the front end of the rear panel 22 is When the portion 22a is flexed and deformed inward, the tip end of the pawl piece 36 and the front end portion 22a are in contact with each other and cannot be connected, or the pawl piece 36 does not contact the front end portion 22a of the rear panel 22. By being located on the outer wall, there is an assembling defect such as a sliding contact and scratches.

Therefore, the worker visually confirms the presence or absence of the above-mentioned connection failure in advance and, as shown in FIG. 8A, for example, the index finger of the hand in a state where it is inserted below the claw piece 36 and grasps the rear end side 16h. With this, when the guide portion 36c side of the claw piece 36 is pushed in the arrow direction from between the rear end side 16h and the front end portion 22a, the guide portion 36c can be largely and smoothly bent inward.

In the above work, the claw piece 36 is formed on the inner wall in the middle or slightly higher than the rear end side height of the hem portion 16b. Since the insertion opening of the holding groove 36a can be largely opened while grasping the portion protruding to the position as a handle, the pushing operation can be performed more easily while maintaining the insertion posture of the left and right claw pieces 36. It has the advantage that it can be performed easily.

Next, when the operator removes the finger and the hand that bend-operate the claw piece 36 before reaching the pushing end position, and pushes it to the slide end position of the bonnet 16 at this time, as shown in FIG. The claw pieces 36 on the end side 16h elastically return to firmly clamp the front end 22a inserted while narrowing the groove between the rear end sides 16h, and fix the entire surface of the wide guide part 36c or The tip end side abuts in a stable posture in which the narrowed inner wall of the rear panel 22 is pressed.

In the embodiment, the riding type transplanter 1 is described as an example, but the present invention can be applied to other traveling vehicles, and the attachment member of the bonnet 16 to the machine body side is the rear panel 22 as the machine body side rear panel member. Alternatively, the operation panel 38 or other member can be used.
Further, for convenience of description, an example in which the hood 16 and the rear panel member 22 are arranged in the front-rear direction has been described, but the same can be applied to a traveling vehicle in which both are arranged in reverse order, and the hood 16 In the case of a large size, a plurality of claw pieces 36 can be arranged in the vertical direction, and the claw pieces 36 can be provided in a protruding shape with a wide width in the vertical direction.
