JP5680832B2 - Nail cover for pre-treatment body in glazing machine - Google Patents

Description

  The present invention relates to a pre-coating machine that cuts earth and sand before shaping a coffin by a trimming body, and has a function of controlling the direction of earth and sand scattering due to the rotation of the claws forming the pre-processing body. The present invention relates to a nail cover for a pretreatment body.

  The pre-treatment body located in front of the trimming body that shapes the heel when the 畦 coating machine is running is crushed by the trimming body that passes after passing the pre-treatment body by the chopping claw breaking and loosening the old sand. Prepare for shaping.

  The pre-processing body's claw claw rotates around the axis oriented in the direction close to the traveling direction of the coating machine, thereby cutting the earth and sand in front of the leveling body and passing it afterwards. A claw cover for restricting the scattering range of the cut earth and sand is attached around the chopping claw in order to send it to the body position (see Patent Documents 1 and 2).

  The claw cover is shaped to cover, for example, the upper side, the tractor side, and the work machine side so that the earth and sand cut by the claw claw will not scatter to the side of the glazing machine and the tractor connected to the tractor. An opening for intensively feeding the cutting soil is formed. Specifically, the nail cover is composed of two plate-like end plates facing each other in the axial direction of the claw claws, and a curved plate-like side plate covering the side surface and the upper side of the claw claws, and the opening is formed on the side plate. It is formed by making a part of the absence.

  A soil receiving material that receives the scattered earth and sand and drops it to the passing position of the trimming body is arranged at the front position of the trimming body, which is the tip (side side) of the opening of the claw cover, and the claws claw cuts the nail. The earth and sand discharged to the outside from the opening of the cover is collected at the front position of the trimming body by the earth receiving material for shaping the bowl by the trimming body.

Japanese Patent Laying-Open No. 2005-58079 (paragraph 0017, FIGS. 1 to 4) JP 2008-43211 A (paragraph 0028, FIGS. 1 and 2)

  However, the tip of the chopping claw protrudes from the opening (see Fig. 3), and the chopping claw rotates several times per second with the running of the glazing machine so as not to clog the cutting earth and sand inside the claw cover. Therefore, it is easy to diffuse the earth and sand scattering range.

  The earth receiving material can only catch the earth and sand scattered in the range, and the tip of the claw claw protruding from the opening can receive the earth and sand scattered and scattered in the width direction from the opening area without leakage. Therefore, it may be difficult to concentrate in front of the trimming body.

  In view of the above background, the present invention proposes a nail cover for a pretreatment body that limits the scattering range of cutting earth and sand by the claw claws of the pretreatment body and allows it to be concentrated in front of the trimming body.

The nail cover for the pre-processing body in the wrinkle coater according to claim 1 receives the power transmitted from the tractor through the transmission frame connected to the support frame connected to the rear of the tractor and in the traveling direction. Rotate around the axis facing in the near direction, and before shaping the cocoon by the rectifying body, enclose the chopping claw for cutting the earth and sand existing in front of the rectifying body, In a pretreatment body of a crease coater comprising a nail cover body having an opening, and a soil receiving material disposed at the tip of the opening of the nail cover body,
A position facing the opening of the nail cover body, the rib cutting pawl and configuration requirements that the direction control member for controlling the direction of sediment to be cut from being scattered toward the soil receiving member are connected.

  Power is transmitted from the transmission frame to the claw claw of the pretreatment body, and the claw claw cuts the soil of the main claw by rotating around the axis, and discharges the cut earth and sand to the outside from the opening of the claw cover. The earth and sand discharged from the opening is received by the earth receiving material, and is used for shaping the new sand by rotating around the axis of the trimming body.

  When the transmission frame is connected to the support frame so as to be swingable in the width direction of the tractor, the offset amount with respect to the support frame can be adjusted. In addition, when the pretreatment body and the trimming body are connected to the transmission frame so as to be rotatable, for example, around the vertical axis, the wrinkle coater can handle both forward work and reverse work.

  Since the opening of the nail cover main body has a role of guiding the earth and sand cut by the chopping claw to the front position of the trimming body, the opening needs to have a size and a shape that do not hinder this function. In other words, if you try to reduce the size of the opening for the purpose of limiting the scattering range of the earth and sand, it will be easier for the earth and sand to stay inside the nail cover body, it will be difficult to collect the earth and sand in front of the trimming body, It is necessary to give a certain size to the opening.

  Depending on the mounting orientation of the rivet claw, it may rotate upward (up-cut rotation) or downward (down-cut rotation) with respect to the side surface (slope) of the main shaft. In any orientation, the position of the opening is determined by the relationship with the earth receiving material that receives the cutting earth and sand scattered from the opening, and the opening is formed at the position where the earth and sand cut by the claw claw is discharged to the earth receiving material side. Is done. The drawings (FIGS. 2, 3, 6, and 7) show an example in which the chopping claw rotates down-cut.

  As described above, the claw cover body is composed of the end plates and side plates located on both sides in the axial direction of the rotating shaft, but the lower part of the claw cover body is the slope of the Xinjiang that the trimming body is going to form (side surface) The side plate on the side where the opening is formed faces the slope side of Xinjiang. Since the section from the lower part of the nail cover body to the side on the slope side of the new wall faces the ground side of the main fence, it is necessary to cut the soil of the main fence in this range. It protrudes from the nail cover body on the surface.

  For this reason, when the earth and sand cut by the chopping claws are guided to the opening along the inside of the nail cover main body, the tendency to diffuse and scatter in the width direction from the opening range in addition to the height direction of the opening is strengthened. .

  Therefore, since the direction control member is connected to the position facing the opening as in the present invention, the range of scattering can be limited at the position where the earth and sand starts to scatter, so the scattering direction depends on the direction of the direction control member. Alternatively, it is possible to freely control the scattering range, and as a result, the earth and sand can be intensively scattered on the earth receiving material side.

  In particular, when the direction control member is connected to the claw cover body so that the orientation of the direction control member can be adjusted (Claim 2), the conditions such as the rotation speed of the claw claw, the traveling speed of the tractor, and the soil condition Since the direction of the direction control member can be freely changed according to the condition, it is possible to set the most rational (optimal) earth and sand scattering range according to the conditions.

  In order to avoid interference (collision) with the chopping claws in principle, the direction control member is arranged outside the opening, but if there is no interference with the chopping claws, a part protrudes outside the opening. It may be fixed inside the opening in a state. Therefore, the “position facing the opening” refers to any position facing the opening side regardless of the inside or outside of the opening (claw cover body). When arranged outside the opening, it is possible to freely set the projecting length from the opening, and the contact time with the earth and sand scattered from the opening becomes longer, so that the control effect on the earth and sand scattered is increased.

  Specifically, the direction control member has a direction control plate that reflects the earth and sand scattered from the opening. In this case, since the direction control plate reflects the earth and sand scattered from the opening and prevents the earth and sand from diffusing in the direction, it is easy to limit the earth and sand scattering range. The earth and sand that scatters from the opening and travels toward the direction control plate collides with the direction control plate and reflects, thereby correcting the scattering direction. When the direction control member is disposed outside the opening as described above, the amount of earth and sand reflected on the direction control plate is increased, so that the effect of controlling the scattering of earth and sand is improved.

  Since the direction control member is connected to the position facing the opening, the range of scattering of the earth and sand can be limited, and the earth and sand can be concentratedly scattered on the earth receiving material side. In particular, since the range of scattering can be limited at the position where the earth starts to scatter, it is possible to freely control the direction or range of the scatter, and it is possible to scatter the earth and sand intensively on the earth receiving material side. It is.

  Hereinafter, the best mode for carrying out the present invention will be described with reference to the drawings.

  FIG. 1 shows a cutting claw 2 that rotates around an axis in response to power transmitted from a tractor 19, and cuts the earth and sand existing in front of the trimming body 8 before shaping the bowl by the trimming body 8. An example of the configuration of a scissor coater 10 that includes a pretreatment body 7 that has a claw cover main body 4 that surrounds the scissors claw 2 and has an opening 5 in part.

  FIG. 2 shows a configuration example of the nail cover 1 for a pretreatment body in which a direction control member 6 for controlling the direction of scattering of earth and sand cut by the claw claw 2 is connected to a position facing the opening 5 of the claw cover body 4. Show. FIG. 2 is an arrow view taken along line xx of FIG.

  As shown in FIGS. 4 and 5, the glazing machine 10 has a top mast 11 and a lower link connecting portion 12 which are connected to a three-point link hitch mechanism comprising a top link and a lower link at the rear of the tractor 19 projecting upward and downward, respectively. A support frame 13 provided, a transmission frame 14 coupled to the support frame 13 so as to be swingable in the width direction of the tractor 19, and connected to the rear of the transmission frame 14 and driven by receiving power from the tractor 19 In addition, the trimming body 8 and the pretreatment body 7 constituting the working machine of the tack coater 10 are provided as basic components.

  The transmission frame 14 is supported by the support frame 13 so as to be rotatable about a rotation axis oriented mainly in the vertical direction, but the rotation axis may be inclined with respect to the vertical. FIGS. 4A and 4B show a state where the glazing machine 10 is supported by the stand 18.

  The transmission frame 14 incorporates a power transmission device such as a transmission shaft and a chain for transmitting the power received from the tractor 19 to the pretreatment body 7 and the trimming body 8, and transmits power to the rear end of the power transmission device. A driven shaft linked to the apparatus is arranged. The driven shaft is connected to a power transmission device such as a transmission frame 14 and is connected to a transmission device such as a gear and a sprocket that transmits power to the pretreatment body 7 and the adjusting body 8 via a power transmission device such as a transmission shaft. The

  The driven shaft and the transmission device are built in the transmission box 15 shown in FIG. 4B and FIG. 5 below the rear end of the transmission frame 14, and power is supplied to the pretreatment body 7 and the adjusting body 8, respectively. The power transmission device for transmitting the power is built in the support arm 16 and the like supported by the transmission frame 14. In the drawing, the power from the transmission device to the adjusting body 8 is directly transmitted from the transmission box 15 without the support arm 16 or the like being interposed.

  The transmission frame 14 can be offset in the width direction of the tractor 19 with respect to the support frame 13 by a cylinder 17 or the like installed between the rear end of the transmission frame 13 and the support frame 13, and the offset amount can be adjusted. Yes. The transmission box 15 is rotatable with respect to the transmission frame by a cylinder or other rotating means provided between the transmission box 15 and the transmission frame 14. FIG. 1 shows a situation when the transmission frame 14 is most offset to the right in the traveling direction with respect to the support frame 13.

  In the drawing, in order to simplify the structure of the wrinkle coater 10, the transmission box 15 is connected to the transmission frame 14 in conjunction with the swinging of the transmission frame 14 by the cylinder 17 installed between the transmission frame 14 and the support frame 13. On the other hand, it can be rotated. In other words, the cylinder 17 is also used as a rotating means for rotating the transmission box 15 so that the rotating means for rotating the transmission box 15 is absent. 14 may be independent of the swinging motion.

  When the transmission box 15 is rotatable with respect to the transmission frame 14, the work machine including the pretreatment body 7 and the trimming body 8 connected to the transmission box 15 is rotatable with respect to the transmission frame 14. Thus, in the work implement, the pretreatment body 7 is positioned in the forward direction of the trimming body 8 during both the forward operation and the reverse operation of the tractor 19.

  As shown in FIGS. 1 and 4, the rectifying body 8 includes a truncated cone-shaped slope grading portion 81 that shapes the slope 20 a of the ridge 20 shown in FIG. 2 by rotation around an axis, and a slope grading portion 81. And an upper surface adjusting portion 82 which shapes the upper surface 20a of the rod 20 and is connected to the transmission frame 14 at the slope adjusting portion 81. .

  The pretreatment body 7 is disposed on the front side of the trimming body 8 on the support frame 13 side with respect to the transmission device (transmission box 15). The pretreatment body 7 receives the power from the power transmission device interlocked with the power transmission device of the transmission frame 14 and rotates around the shaft, cuts the earth and sand existing in front of the trimming body 8, and passes the trimming body afterwards. 8 is provided with a claw claw 2 to be fed forward, and a claw cover body 4 surrounding the claw claw 2 and having an opening 5 in a part thereof.

  In order to reliably discharge the earth and sand cut by the claw claw 2 from the opening 5 of the claw cover main body 4, a sweeping claw 3 is connected to the rotary shaft 2a of the claw claw 2 as shown in FIGS. The cut earth and sand are mainly discharged by the sweeping claw 3. As shown in FIG. 1 and FIG. 4, the soil and sand scattered as shown in FIGS. 1 and 4 are received at the front side of the trimming body 8 which is the front side of the opening 5 of the claw cover body 4, that is, the front side of the pretreatment body 7. The earth receiving material 9 to be dropped at the passing position of the trimming body 8 is arranged.

  The claw cover main body 4 of the pretreatment body 7 is located on both sides in the axial direction of the scissor claw 2 and is composed of two end plates 41 and 42 facing each other and a side plate 43 covering the side surface and the upper side of the scissor claw 2, An opening 5 is formed in a part of the side plate 43 on the side of the earth receiving material 9 so as to cover both sides and the upper side in the axial direction and the side surface of the claws 2. The opening 5 is formed by making a part of the side plate 43 on the side of the trimming body 8 absent or notching as shown in FIGS.

  2 and 3 show an example of the case where the scissor claw 2 rotates down-cut as described above. According to the direction of this rotation, the opening 5 and the direction control member 6 are arranged above the claw cover body 4 in the drawings. Placed in position. When the scissor claw 2 rotates up-cut, the opening 5 and the direction control member 6 are arranged in a range from a slope part 45 to a side part 46 described later.

  As shown in FIG. 2, the end plates 41 and 42 of the nail cover body 4 are positioned at a level where the lowermost part 44 is in contact with the farm scene, and the sloped part 45 on the soil receiving material 9 side of the lowermost part 44 is newly provided. An inclination substantially along the slope 20a of the Xinjiang 20 to be shaped is added. The slope angle of the slope 45 is changed by connecting a guide plate 42a, which is a separate member, to the end plate 42 in a fixed state so that the angle can be adjusted, as shown in FIGS. Is also possible. In FIG. 2, a two-dot chain line parallel to the upper surface 20 b of the fresh potato 20 indicates a farm scene.

  The front end of the scissor claw 2 protrudes (exposes) from the end plates 41 and 42 within the range of transition from the side surface portion 46 rising upward from the slope portion 45 to the slope portion 45 side on the elevation surface of the claw cover body 4. Cutting the soil. In the range from the uppermost portion 47 to the side surface portion 46 of the nail cover main body 4, since the chopped claw 2 is exposed in the air, the tendency for the earth and sand cut by the chopped claw 2 to be scattered increases.

  As shown in FIGS. 1 and 2, the earth receiving material 9 is arranged at the position of the opening 5 of the claw cover body 4 or a position covering the vicinity of the opening 5, and receives and drops the earth and sand discharged from the opening 5. The lower receiving material 92 is located below the upper surface 20b and below the upper surface 20b, and dams up the earth and sand from the upper receiving material 91 on the main fence.

  As shown in FIGS. 1 and 4- (a), the earth receiving material 9 covers the entire width of the claw cover body 4 from the outer peripheral position of the claw cover body 4 from the center (rotary shaft 2a) of the claw cover body 4. Since the width increases as the distance increases, even if the earth and sand scattered from the nail cover main body 4 may spread on the plane from the pretreatment body 7 side to the trimming body 8 side, It is possible for the material 9 to catch most of the earth and sand.

  Accordingly, there is also the direction of rotation (down cut) of the claw cutting claw 2, and the claw claw 2 has been cut at a position closer to the lower side of the end plate 42 located closer to the trimming body 8 in the claw cover body 4. A notch 48 for facilitating the discharge of earth and sand to the earth receiving material 9 side is formed, and the direction control member 6 is disposed above the notch 48 in the drawing.

  The direction control member 6 is disposed and connected (fixed) to any one of the end plates 41 and 42 constituting the claw cover body 4 or the side plate 43 facing the opening 5. Since it is a position facing the opening 5, there are a case of the end plates 41 and 42 located on both sides of the opening 5 and a case of the side plate 43 located above and below.

  However, the pretreatment body 7 always cuts the soil of the main fence while moving at a speed while maintaining the state of being positioned forward of the traveling body 8 with respect to the trimming body 8, so that the cut earth and sand are on the front side in the traveling direction. Since there is a tendency toward the rear side in the traveling direction, the direction control member 6 is fixed to the end plate 42 on the trimming body 8 side (rear side) of the end plates 41 and 42 on both sides in the drawing.

  The direction control member 6 has a direction control plate 61 that reflects earth and sand scattered from the opening 5 of the claw cover body 4 and is connected (fixed) to the claw cover body 4 in a state in which the direction (direction) of the direction control plate 61 can be adjusted. ) The direction control member 6 is detachably connected to the end plates 41 and 42 or the side plates 43 constituting the claw cover main body 4 in a fixed state or in an exchangeable manner.

  The direction control member 6 may have any configuration as long as it has a direction control plate 61. However, in order to facilitate adjustment of the direction of the direction control plate 61 in the drawings, as shown in FIGS. The direction control member 61 includes a direction control plate 61, a shaft member 62 integrated with the direction control plate 61, and an upper holding member 63 and a lower holding member 64 that hold both end portions of the shaft member 62 so as to be rotatable about the axis. A receiving member 65 for receiving the upper holding member 63 is fixed to the surface of the end plate 42 in order to assist the fixing of the upper holding member 63 and the lower holding member 64 to the end plate 42. The shaft member 62 is fixed to the end plate 42 (41) or the like in a state parallel to the surface of the opening 5 formed by the end plates 41 and 42, and the direction control plate 61 is like a door that opens and closes the opening 5 with respect to the opening 5. Behaves.

  The direction control plate 61 is pivotally supported by the upper holding member 63 and the lower holding member 64 at both ends of the shaft member 62, so that the angle with respect to the end surface (exit) of the opening 5 can be adjusted. The upper holding member 63 has a larger area than the lower holding member 64 for restraining the direction control plate 61 by the restraining member 66 described later, and the shaft of the shaft member 62 as shown in FIGS. 7A and 7B. When viewed in the direction, it has a shape projecting from the lower holding material 64 to the earth receiving material 9 side.

  The receiving member 65 has a receiving portion 65a that overlaps the lower surface side of the upper receiving member 63 and a joining portion 65b that overlaps the surface of the end plate 42, and is fixed to the surface of the end plate 42 by welding or the like at the joining portion 65b. In the drawing, in particular, in order to give the receiving member 65 a function of holding the space between the upper holding member 63 and the lower holding member 64, the lower holding member 64 is integrated with the lower end portion of the joint portion 65b, and the receiving portion 65a facing the receiving portion 65a. The receiving material 65 is formed in a groove shape from the lower holding material 64 and the joint portion 65b connecting the both. The upper receiving member 63 and the receiving portion 65a that overlap each other are joined together by bolts or the like.

  The angle of the direction control plate 61 with respect to the opening 5 is adjusted by rotating the shaft member 62 with respect to the upper holding material 63 and the lower holding material 64. It is held by a restraining member 66 that restrains it. In the drawings, as shown in FIGS. 6 to 8, the fixing member 661 fixed to the surface opposite to the opening 5, which is one surface of the direction control plate 61, the upper holding member 63, and the fixing member 661 are connected to the shaft member 62. A constraining member 66 is composed of a pin 662 penetrating in the axial direction and an operation member 663 rotatably connected to an upper portion of the pin 662.

  The fixing member 661 has an upper plate 661a and a lower plate 661b that are opposed to each other in the vertical direction, and the pin 662 passes therethrough, and the operation member 663 is an engaging portion that can engage with the lower surface of the lower plate 661b of the fixing member 661 at the lower end. Hook) 663a. The operation member 663 functions as a spring for maintaining the state where the pin 662 is restrained by the fixing member 661 when the engaging portion 663a is engaged with the lower plate 661b.

  The operation member 663 receives a downward force from the lower plate 661b when the engaging portion 663a is engaged with the lower surface of the lower plate 661b of the fixing member 661, thereby pulling the pin 662 downward (to the engaging portion 663a side). The pin 662 is held in a state of penetrating the fixing member 661. The operation member 663 releases the action of the force on the pin 662 when the engaging portion 663a is released from the lower plate 661b, and allows the pin 662 to be detached from the fixing member 661.

  When the engaging portion 663a is engaged with the lower plate 661b of the fixing member 661, the operation member 663 tends to extend in the axial direction of the pin 662, and thus the force to restore the original shape is applied to the fixing member 661 against the pin 662. Acts toward the side. As a result, the state where the pin 662 penetrates the upper plate 661a and the lower plate 661b of the fixing member 661 is maintained, and the direction control plate 61 is maintained (locked).

  When the engaging portion 663a is disengaged from the lower plate 661b, the force that pushes the pin 662 toward the fixing member 661 is released, and the pin 662 is pulled out of the fixing member 661 as it is, so that the restraint of the direction control plate 61 is released. Is done.

  When the direction control member 6 has the configuration (form) shown in the figure, the adjustment of the direction (direction) of the direction control plate 61 is determined by the position of the pin 662 penetrating the upper holding member 63, so that the pin 662 penetrates the upper holding member 63. By providing a plurality of positioning holes 63a, the direction of the direction control plate 61 can be adjusted in multiple stages. The positioning hole 63a is formed on an arc centered on the center of the shaft member 62 as shown in FIG. If these positioning holes 63a are continuous in the circumferential direction, the direction of the direction control plate 61 can be adjusted steplessly.

  In that case, a locking means for preventing the pin 662 from easily moving in the circumferential direction along the positioning hole 63a is required. As a locking means in this case, for example, a state in which it is normally projected by the restoring force toward the positioning hole 63a side in the circumferential direction is maintained, and either one of the radial directions is resisted against the restoring force when the pin 662 passes. A spring of the type that enters the side of is used.

  Since the operation member 663 rotates with respect to the upper holding member 63 around the center of the shaft member 62 together with the pin 662, the edge of the upper holding member 63 along which the operation member 663 moves is also shown in FIG. As shown, it has an arc shape centered on the center of the shaft member 62.

  The direction control plate 61 enlarges the area of the opening 5 when it is in a state parallel to the end plates 41 and 42 constituting the claw cover body 4 or in a state facing the trimming body 8 side from the end plates 41 and 42. The area of the opening 5 is reduced when facing the direction close to the rotation axis 2a of the chopping claw 2, and the opening width of the opening 5 is adjusted within a range in which this direction can be adjusted, and the scattering range of earth and sand is controlled.
