Description

  The present invention relates to a roll baler that picks up a molding material made of the molding material and compresses it to form a roll bale.

  As prior art document information related to the roll baler according to the present invention, for example, there is the following Patent Document 1.

Japanese Patent No. 3486390

  Patent Document 1 describes a roll baler provided with a cutting knife for cutting a material to be molded such as picked grass before feeding it into a molding chamber. The cutting knife is disposed on the floor plate, which is a conveyance path for the molding material, and when the scraping rotor disposed above the cutting knife feeds the molding material into the molding chamber, the cutting knife cuts the molding material. Like to do.

  The floor plate is pivotally supported so that the molding chamber side (downstream side) descends with the pickup device side (upstream side) as a fulcrum, and the fixed position is held by holding means. The holding means is connected to a lock releasing means for releasing the holding of the floor plate in conjunction with the cutting knife when a force exceeding the force received during normal operation is applied to the cutting knife.

  That is, when a large amount of molding material exceeding the processing capability of the cutting knife is fed and a force exceeding the force received during normal operation of the cutting knife is applied, the lock releasing means releases the holding of the floor board by the holding means. Then, the molding chamber side of the floor plate released from holding is lowered, and the molding chamber side of the floor plate is opened downward, so that the molding material on the floor plate is released outside the machine. Therefore, it is possible to prevent clogging in the cutting device of the material to be molded being conveyed.

  By the way, in the structure for preventing clogging of the molding material, when returning the lowered floor board to a fixed position, an operator performs hydraulic operation from a traveling vehicle. Therefore, it is necessary for the operator to confirm that the molding material that causes clogging has been released to the outside of the machine, but since the molding material is automatically released outside the machine, the molding material is always Assuming that the material is clogged, it is necessary to visually confirm the amount of the molding material to be picked up and confirm that the molding material has been released to the outside of the machine. However, the confirmation of the material to be formed by visual observation during the running operation of the roll baler that requires continuous work is a work load on the operator during the roll baler operation.

  Patent Document 1 also proposes that a clogging of a molding material and release of the molding material to the outside of the machine are detected by a sensor, and the floorboard is automatically opened and closed. However, because the environment in which the roll baler is used is a place where there are many deposits of water, soil, and dust, such as in fields and pastures, and there are very many irregularities, errors due to sensor deviations due to these deposits and irregularities, etc. Since detection is likely to occur, it is necessary to frequently perform maintenance of the sensor.

  In addition, there are many components for opening and closing the floor plate such as the holding means, the lock release means, the hydraulic cylinder and the piping for returning the floor plate, and the sensor, etc. However, since many costs such as maintenance cost, parts cost, and manufacturing cost are required, the price of the roll baler itself is increased and the running cost may be increased.

  An object of the present invention is to deal with such a problem. That is, it is an object of the present invention to reduce the work load on the operator, facilitate maintenance, reduce various costs, and the like.

  EMBODIMENT OF THE INVENTION Hereinafter, the form for implementing the roll baler concerning this invention is demonstrated based on drawing.

  The roll baler A according to the present embodiment has a well-known basic structure, and a detailed description thereof will be omitted. However, as shown in FIG. 1, a tractor such as a tractor (not shown) is connected via a connecting rod 15. ) And towed. Further, as shown in FIGS. 1 and 2, the pick-up device 1 is formed by the driving force taken out from the driving shaft of the towing vehicle through a PTO (Power Take Off) shaft (not shown) so that the pasture such as pasture in the field is molded. A material (not shown) is picked up, the picked-up molding material is conveyed to the rear forming chamber 2, and a cylindrical roll bale (not shown) is compression-molded in the forming chamber 2. Further, a covering material A1 such as a net material wound around the compression-rolled roll bale is held in the molding chamber 2 so that it can be fed out, and after the winding of the covering material A1 is completed in the molding chamber 2, the rear side of the molding chamber 2 is opened. The roll bale is discharged.

  In the following, the pickup device 1 side is the upstream side in the transport direction, the molding chamber 2 side is the downstream side in the transport direction, the direction orthogonal to the transport direction in the horizontal direction is the machine width direction, and the direction intersecting the transport direction is the vertical direction. Is called the vertical direction.

  The pickup device 1 includes a plurality of pickup tines 11 arranged at equal intervals along the axial direction on a rotary shaft 10 having an axial direction as a machine width direction and an axial center as a rotation center. By rotating, the material to be molded is caught and picked up.

  As shown in FIG. 1 to FIG. 7, a cutting portion B that cuts the molding material picked up by the pickup device 1 is provided between the pickup device 1 and the molding chamber 2. Hereinafter, the form of the cutting part B will be specifically described with reference to FIGS.

  The cutting part B includes a floor plate 3 serving as a conveyance path for conveying the molding material to the molding chamber 2, a cutting knife 4 for cutting the molding material conveyed on the floor plate 3, and the molding material in the molding chamber. 2 and a feeding rotor 5 for feeding into the machine 2. By the feeding operation of the feeding rotor 5, the cutting knife 4 cuts the material to be molded.

  The floor plate 3 is pivotally supported so as to be rotatable in the vertical direction around the axis of the support shaft 3A with respect to the support shaft 3A provided on the upstream end side along the machine width direction. The downstream end side moves up and down as the fulcrum rotates. Then, the space between the floor plate 3 and the feeding rotor 5 is expanded by the lowering of the downstream end side of the floor plate 3, and the expansion acts on the feeding rotor 5 when the conveyance amount of the molding material increases. The load due to the molding material can be reduced, the engine speed of the towing vehicle can be prevented from decreasing due to the increase in the load, and the molding material can be smoothly fed into the molding chamber 2. (See FIGS. 3 and 4).

  The downstream end side of the floor board 3 is supported by a support member 6 having a holding force for holding the origin position of the floor board 3. The support member 6 contracts according to the pressure when the conveying pressure of the molding material exceeds the holding force and acts in the direction in which the floor plate 3 is lowered with respect to the floor plate 3 and the cutting knife 4. Thus, the lowering of the floor plate 3 is not hindered, and the space between the floor plate 3 and the feeding rotor 5 is expanded. Further, when the pressure becomes less than the holding force, the floor plate 3 is automatically raised to return to the origin position by extending against the pressure.

  That is, when the amount of the molding material picked up is large and becomes clogged with the cutting part B, the downstream end of the floor board 3 is automatically moved by the contraction of the support member 6 according to the pressure acting on the floor board 3. And the space between the floor plate 3 and the feeding rotor 5 is expanded to smoothly feed the clogged molding material into the molding chamber 2 and prevent the molding material from clogging at the cutting portion B. it can. Further, when the molding material in a clogged state is fed into the molding chamber, and the amount of the molding material picked up continuously is not such an amount that the clogging portion B is clogged, the support member 6 expands and the floor plate 3 Returns to the home position. Therefore, the operator who travels the roll baler A is not subjected to a work load such as confirming the amount of the molding material picked up or confirming that the molding material has been discharged to the outside of the machine. Can be.

  Further, since the operation of extending and contracting the support member 6 and a sensor for detecting pressure are not required, the vertical movement of the floor plate 3 can be controlled by the expansion and contraction operation by the pressure acting on the support member 6 itself. It is possible to reduce the number of parts related to the structure that moves up and down. Therefore, overall maintenance is easy, and many costs such as maintenance cost, parts cost, and manufacturing cost can be reduced, so that the price of the roll baler A itself can be suppressed and the running cost can be reduced. Can be reduced.

  Examples of the support member 6 include a cylindrical liquid damper, a gas damper, a spring damper, and the like, and preferably have a function of adjusting the holding force. In addition, the origin position of the floor plate 3 referred to here is a position in a normal working state where the workpiece to be conveyed is cut without being expanded between the floor plate 3 and the feeding rotor 5 and is fed into the molding chamber 2. is there.

  In this embodiment, it illustrated as a form which supported the support member so that a floor board might be supported from the bottom, However, In this invention, the form which supported the support member so that a floor board may be suspended from the upper part is also contained. The support member used in this embodiment is in a contracted state when the floor board is at the origin position, and the contraction force is used as a holding force for holding the floor board at the origin position, and pressure exceeding the holding force is applied to the floor board and the cutting knife. When the pressure is applied, the floor board is lowered and the floor board is lowered. When the pressure becomes less than the holding force, the floor board is contracted to return the floor board to the origin position (not shown).

  A plurality of cutting knives 4 are arranged at equal intervals along the machine width direction with the blades facing upstream. The cutting knife 4 is provided so as to move up and down integrally with the floor board 3. The cutting knife 4 may move from the fixed position to the downstream side with respect to the floor plate 3 and may return from the moved position to the fixed position.

  In the feeding rotor 5, a plurality of claw members 51 are arranged at equal intervals along the axial direction on a rotating shaft 50 provided with the axial direction as the machine width direction and the axial center as the rotational center. The claw member 51 of the present embodiment is composed of three claws 510 protruding outward in the radial direction of the rotating shaft 50, and the claw 510 rotates with the rotation of the rotating shaft 50 to transfer the material to be molded. It scrapes and sends it to the molding chamber 2 on the downstream side.

  Hereinafter, specific embodiments of the support member 6 will be described. FIGS. 3 and 4 show the first embodiment of the support member 6. In the present embodiment, the two support members 6 support both ends of the downstream end of the floor board 3 in the machine width direction. The support member 6 has an upper end connected to a shaft support portion 30 provided at the downstream end of the floor plate 3 and a lower end provided below the downstream end of the floor plate 3 around the support body 7 arranged in a fixed position. It is connected to the shaft support portion 70 formed. The upper and lower ends of the support member 6 are pivotally supported so as to be rotatable about the axis in the axis direction. The support member 6 arranged in this manner supports the downstream end of the floor board 3 so that the origin position of the floor board 3 is maintained, and the floor board 3 contracts as the downstream end of the floor board 3 descends and is fed into the floor board 3. The space between the rotor 5 and the rotor 5 can be expanded, and the downstream end side of the floor board 3 can be raised (returned to the origin position) by extension.

  A plurality of shaft support portions 30 and 70 are provided at equal intervals along the machine axis direction, and the number of support members 6 is changed (see FIG. 5), or the shaft support portions 30 and 70 to which the support members are attached are changed. (Not shown). A plurality of (three in the drawing) support holes 71 are formed in the shaft support portion 70 along the transport direction, and the shaft support position of the lower end of the support member 6 can be changed (see FIG. 6). With such a configuration of the shaft support portions 30 and 70, the number of support members 6 is made optimal according to the pressure acting on the floor plate 3 and the cutting knife 4, or the shaft support position of the lower end of the support member 6 is changed. As a result, it is possible to suppress malfunction of the cutting part B, and it is possible to improve the certainty of cutting the molding material having the assumed amount and physical properties and feeding the cut molding material into the molding chamber 2.

  The support 7 is arranged with its longitudinal direction along the axis direction, and both ends thereof are fixedly supported on the downstream side of the support plate 8 provided on the side plate A2 which is a stationary portion of the roll baler A. The support plate 8 is located outside the side plate A2 and is pivotally supported by a rotation shaft 80 provided with the axial direction as the machine width direction and the axis as the center of rotation, and the origin position of the floor plate 3 Is supported by a rotation restricting portion 9 for stopping and releasing the rotation.

  The rotation restricting portion 9 fixes the support 7 to a position where the support member 6 holds the origin position of the floor plate 3 (rotation stopped state) and rotates (releases the rotation stop) to fix the support 7. It will be lowered. When the support body 7 is lowered, the support member 6 connected to the support body 7 and the downstream end side of the floor board 3 connected to the support member 6 are also lowered together, and the downstream end side of the floor board 3 is outside the machine. The space between the downstream end side of the floor plate 3 and the molding chamber 2 can be opened so as to face downward (see FIG. 7). For example, when the material to be molded is completely packed in the cutting part B, the operator releases the rotation restricting part 9 to stop the rotation of the rotation restricting part 9 for the removal work of the molding material and the cleaning and maintenance after the forming operation of the roll bale. The operation can be performed by opening the space between the downstream end side of the floor plate 3 and the molding chamber 2.

  The rotation restricting portion 9 of the present embodiment penetrates the support plate 8 in the axial direction so as to be rotatable about the slide and the axial center, and to the fitting hole A21 opened in the side plate A2. A slide shaft 90 fitted from the outside, an operation lever 91 fixed so as to protrude radially outward at an end opposite to the fitting side of the slide shaft 90, and the operation lever 91 are engaged. An inclined cam plate 92 and a compression spring 93 having a repulsive force that holds the slide shaft 90 fitted are provided.

  The slide shaft 90 is rotated by the rotation operation of the operation lever 91, and the rotation operation lever 91 is engaged with the inclined portion 920 of the inclined cam plate 92 to be rotated and guided to slide in the axial direction. Like to do. The inclined portion 920 of the cam plate 92 is inclined in such a manner that the protruding width from the base end portion toward the terminal end portion is gradually increased outward (in the direction away from the side plate A2) with the support plate 8 surface as the base end portion. In a state where the operation lever 91 is engaged with the base, the support plate 8 in which the slide shaft 90 is fitted into the fitting hole A21 is in a stopped state.

  When the operation lever 91 is rotated in the direction from the base end portion to the terminal end portion of the inclined portion 920 from the rotation stop state, the operation lever 91 moves outward. As the operating lever 91 moves in the outward direction, the slide shaft 91 slides against the repulsive force of the compression spring 93, and the fitting side end of the slide shaft 90 escapes from the fitting hole A21. The rotation stop of the support plate 8 is released. When the floor plate 3 is returned to the origin position, the support plate 8 is rotated upward until the floor plate 3 reaches the origin position, and the operation lever 91 is rotated to the base end of the inclined portion 920 at the origin position. Due to the repulsive force of the spring 93, the fitting side end of the slide shaft 90 is fitted into the fitting hole A21, and the support plate 8 is stopped from rotating.

  The fitting-side end portion of the slide shaft 90 constitutes a part of the vertical movement restricting portion 9A that stops the vertical movement of the floor board 3 at a set position. Hereinafter, the fitting side end portion of the slide shaft 90 is denoted by reference numeral 90A, and the fitting side end portion is described as a locking projection.

  The vertical movement restricting portion 9 </ b> A of the present embodiment includes a locking projection 90 </ b> A and a locking plate 91 </ b> A provided on the lower surface of the floor plate 3 as a configuration for controlling the lowering of the floor plate 3, and a configuration for controlling the rising of the floor plate 3. The extension limit of the support member 6 is set to the position of the floor board 3 in the normal working state.

  The locking plate 91 </ b> A is provided at a position where the locking plate 91 </ b> A is engaged with the locking projection 90 </ b> A when the floor plate 3 is lowered by the contraction of the support member 6. The position of the locking projection 90A is such that when the locking plate 91A is engaged, the space between the floor plate 3 and the feeding rotor 5 is expanded, and the clogged molding material can be fed into the molding chamber 2. It is set to the position to perform. The supporting member 6 prevents the floor board 3 from rotating upward from the normal working state by holding the floor board 3 in the normal working state at the extension limit position.

  That is, since the vertical movement restricting portion 9A prevents excessive vertical movement of the floor board 3 due to expansion and contraction of the support means 6, the distance between the floor board 3 and the feeding rotor 5 can always be kept appropriate. The locking protrusion 90A may be independently provided regardless of the fitting side end of the slide shaft 90, but by using the fitting side end of the slide shaft 90 as the locking protrusion 90A, This can contribute to a reduction in the number of parts for forming the locking projection 90A and a reduction in the processing parts. The configuration for restricting the rise of the floor plate 3 in the vertical movement restricting portion 9 </ b> A of the present embodiment regulates the rise of the floor plate 3 using the illustrated extension limit of the support member 6. It is good also as a structure which provided the engaging part etc. which this floor board engages in the normal working state position, and prevents a raise further.

  8 and 9 show a second embodiment of the support member 6. The support member 6 of the present embodiment includes a rotating link body 6A that is pivotally supported with respect to a side plate A2 that is a stationary portion of the roll baler A so as to be rotatable about an axis along the machine width direction, and the floor plate 3. It is connected with the floor board 3 via the engaging body 6B provided so that it might engage with the rotation link body 6A with respect to the shaft support part 30 of this. That is, the pressure acting on the floor plate 3 contracts the support member 6 from the engaging body 6B via the rotating link body 6A, and the extension of the supporting member 6 raises the floor plate 3 from the rotating link body 6A via the engaging body 6B. I try to let them.

  The specific attachment structure of the rotation link body 6A is such that a rotation support shaft P1 (shown by hatching) that penetrates and attaches to the upper end side of the rotation link body 6A is rotatably supported by the side plate A2, and the lower end side. The upper end of the support member 6 is pivotally supported so as to be rotatable about an axis along the axis direction. The lower end of the support member 6 is fixedly connected to the shaft support portion 70 (not shown) as in the first embodiment.

  An engaging groove 6C that engages with the engaging body 6B is formed on the upstream side edge of the rotating link body 6A, and the engaging body 6B that moves up and down as the floor plate 3 moves up and down always becomes the engaging groove 6C. They are engaged with each other. Further, the rotating link body 6A transmits the holding force of the support member 6 to the floor board 3 via the engaging body 6B, thereby holding the origin position of the floor board 3, and the descending direction of the floor board 3 exceeding the holding force. The support member 6 is pivoted in a contracting direction due to the pressure of the shaft, and the support member 6 is pivotally supported so as to rotate in a direction in which the floor plate 3 is lifted through the engaging body 6B.

  The surfaces of both end portions of the engaging groove 6C are surfaces constituting the vertical movement restricting portion 9A of the floor plate 3, and hereinafter, the upper surface is referred to as an ascending restricting surface 93A, and the lower surface is referred to as a descending restricting surface 94A. .

  When the floor board 3 is at the origin position, the engaging body 6B engages with the rise restricting surface 93A, thereby restricting the turning of the turning link body 6A and restricting the further raising of the floor board 3. When the floor board 3 is lowered, the engaging body 6B engages with the lowering restricting surface 94A, thereby restricting the rotation of the rotating link body 6A and further restricting the lowering of the floor board 3. That is, the distance between the rising restriction surface 93 </ b> A and the lowering restriction surface 94 </ b> A becomes the vertical movement range of the floor board 3.

  The vertical movement restriction position of the vertical movement restricting portion 9A with respect to the floor board 3 also maintains the normal working state without expanding between the floor board 3 and the feeding rotor 5 when the engaging body 6B is engaged with the rising restriction surface 93A. When the engaging body 6B is engaged with the lowering restricting surface 94A (see FIG. 8), the space between the floor plate 3 and the feeding rotor 5 expands, and the molding material in a clogged state is transferred to the molding chamber 2. It is set to a position that holds the state that can be sent (see FIG. 9). Therefore, the same effect as the vertical movement restricting portion 9A exemplified in the first embodiment can be obtained.

  10 and 11 show a third embodiment of the support member 6. The support member 6 of the present embodiment is a rotation link body 6A that is pivotally supported by the shaft support portion 30 of the floor plate 3 so as to be rotatable about an axis along the machine width direction as a rotation center, and a stationary portion of the roll baler A. The side plate A2 is connected to the floor plate 3 via an engagement body 6B provided to engage with the rotation link body 6A. That is, the pressure acting on the floor plate 3 contracts the support member 6 from the engaging body 6B via the rotating link body 6A, and the extension of the supporting member 6 raises the floor plate 3 from the rotating link body 6A via the engaging body 6B. I try to let them.

  The specific attachment structure of the rotation link body 6A is such that a rotation support shaft P2 (shown by hatching) penetratingly attached to the central portion of the rotation link body 6A is rotatably supported by the shaft support portion 30 of the floor plate 3. The upper end of the support member 6 is pivotally supported on the lower end side with the rotation support shaft P2 as a boundary so as to be rotatable about an axis along the axis direction. The lower end of the support member 6 is fixedly connected to the shaft support portion 70 (not shown) as in the first embodiment.

  An engaging groove 6C that engages with the engaging body 6B is formed on the upper end side and the downstream edge side with the pivotal support portion of the rotating link body 6A as a boundary, and moves up and down as the floor plate 3 moves up and down. The engaging body 6B is always engaged with the engaging groove 6C of the rotating link body 6A. Further, the rotation link body 6A transmits the holding force of the support member 6 to the floor plate 3 to hold the origin position of the floor plate 3, and the support member 6 is moved by the pressure in the descending direction of the floor plate 3 exceeding the holding force. It is pivotally supported so as to rotate in the direction of contraction and to rotate in the direction of raising the floor board 3 via the engaging body 6B by extension of the support member 6.

  The surfaces of both end portions of the engagement groove 6C are surfaces constituting the vertical movement restricting portion 9A of the floor plate 3, and hereinafter, the lower surface is referred to as an ascending restricting surface 93A, and the upper surface is referred to as a descending restricting surface 94A. .

  When the floor board 3 is at the origin position, the ascent restricting surface 93A engages with the engaging body 6B, thereby restricting the rotation of the rotating link body 6A and further restricting the floor board 3 from rising. When the floor board 3 is lowered, the lowering restricting surface 94A engages with the engaging body 6B, thereby restricting the rotation of the rotating link body 6A and further restricting the lowering of the floor board 3.

  The vertical movement restriction position of the vertical movement restricting portion 9A with respect to the floor board 3 also maintains the normal working state without expanding between the floor board 3 and the feeding rotor 5 when the rising restriction surface 93A is engaged with the engaging body 6B. When the lowering restricting surface 94A is engaged with the engagement body 6B, the space between the floor plate 3 and the feeding rotor 5 is expanded and the clogged material to be molded is transferred to the molding chamber 2. It is set to a position that holds the state that can be fed (see FIG. 11). Therefore, the same effect as the vertical movement restricting portion 9A exemplified in the first embodiment can be obtained.

  Also according to the second embodiment and the third embodiment, confirmation of the amount of the molding material to be picked up and confirmation that the molding material has been fed into the molding chamber 2 for the operator operating the roll baler A. It is possible not to give a work load that is performed visually. Further, since the operation of extending and contracting the support member 6 and a sensor for detecting pressure are not required, the vertical movement of the floor plate 3 can be controlled by the expansion and contraction operation by the pressure acting on the support member 6 itself. It is possible to reduce the number of parts related to the structure that moves up and down. Therefore, overall maintenance is easy, and many costs such as maintenance cost, parts cost, and manufacturing cost can be reduced, so that the price of the roll baler A itself can be suppressed and the running cost can be reduced. Can be reduced.

  In the second embodiment and the third embodiment, the number of support members can be changed, and the support position of the support member with respect to the rotating link body can be changed to act on the floor board and the cutting knife. By optimizing the number of support members 6 according to the pressure or changing the pivot support position of the lower end of the support member 6, it is possible to suppress malfunction of the cutting part and to cover the expected amount and physical properties. It can be expected to improve the certainty of cutting the molding material and feeding the cut molding material to the molding chamber 2 (not shown). In 2nd Embodiment and 3rd Embodiment, description about the site | part which overlaps with 1st Embodiment was abbreviate | omitted by attaching | subjecting the same code | symbol to FIGS.

  The present invention is not limited to the illustrated embodiments, and can be implemented with configurations within a scope that does not deviate from the contents described in the claims. For example, the roll baler exemplified in the above embodiment is a form in which the picked-up molding material is cut before being sent to the molding chamber, and the cut molding material is fed into the molding chamber. It is not limited to the form, and is also included in a roll baler (not shown) in which the picked-up molding material is directly fed into the molding chamber. In the above embodiment, the state in which the material to be molded is fed into the molding chamber is maintained even when the space between the floor plate and the feeding rotor is expanded. However, the present invention is not limited to the illustrated mode. If the material to be molded is transported and the material to be molded becomes clogged even if the space between the floor plate and the feeding rotor is expanded, the floor plate is further lowered to the downstream end side of the floor plate. The molding material to be conveyed may be opened between the molding chamber and the molding chamber so as to be discharged out of the machine. (Not shown).
