Description

  The present invention provides a self-propelled material in which a molding material picked up by a pick-up device provided on the front surface of a machine body that runs on its own is fed by a conveyor into a molding chamber of a bale molding device provided at the rear part of the machine body and formed into a roll bale. The present invention relates to an improvement in pick-up feeding means for picking up a material to be molded and feeding it into a molding chamber of a bale molding apparatus.

  In a self-propelled roll baler, the technical means to pick up the material to be molded such as grass, rice straw, wheat straw, etc. that have been cut down and left in the field, and send it to the molding room of the bale molding device is a conventional technique. 1. As shown in FIG. 2, a conveyor device b is mounted on the front surface of the entrance a of the molding chamber 20 of the bale molding device 2 that can be mounted on the rear part of the airframe 1 that runs on its own, and the conveyor device b The pickup device c is mounted on the front surface of the front end of the machine body 1 at the front end of the machine body 1, and the molding material picked up by the pickup device c is transferred to the front end of the conveyor device b. The apparatus b is configured to be conveyed toward the inlet a of the molding chamber 20 of the bale molding apparatus 2 and sent into the molding chamber 20.

  And the pick-up apparatus c and the conveyor apparatus b in this technical means are the width | variety corresponding to the opening width | variety of the inlet_port | entrance of the molding chamber 20 which accepts the molding material of the bale molding apparatus 2 in the conveyor apparatus b. In addition, the width of the pickup device c is configured to be equal to the width of the conveyor device b, and the inlet a of the molding chamber 20 is molded to be the width of the molding chamber 20. Since the opening is made corresponding to the width of the forming roll, it is formed to have a width substantially the same as the width of the forming roll.

In the self-propelled roll baler configured to pick up the material to be molded by the pickup device and send it to the bale molding device by the conveyor device, the following problems have occurred.
1. A pick-up device provided at the front end of the machine body is made as wide as the width of the forming roll formed in the forming room of the bale forming device, and the crop length of feed crops with high plant height among the molding materials is long Cannot be picked up when it is cut down and left in the field. In order to pick up the molding material having a long heel length, an incidental operation of collecting the molding material and cutting it with a cutting device is required.
2. In addition, even if the width of the pick-up device is widened to pick up a long molding material, the width of the conveyer device located behind the pick-up device is narrow, so that the transfer section between the pick-up device and the conveyer device As a result, stagnation of the material to be molded that has been picked up occurs, which makes conveyance to the entrance of the molding chamber of the bale molding apparatus a problem.
3. Moreover, even if it passes through the delivery part, the material to be molded swells upward, and the deposition height on the conveying surface of the conveyor device increases, which may cause clogging at the entrance of the molding chamber of the bale molding device.
4). In addition, if the width of the conveyor device is increased in conjunction with the expansion of the pickup device, the material to be molded will clog the inlet of the molding chamber. To widen the inlet to eliminate this, the bale molding device The whole must be remodeled.

  The problem to be solved in the present invention is to widen only the width of the pickup device provided at the front end of the machine body and to pick up the molding material having a long wall length, while the transfer unit between the pickup device and the conveyor device and the molding It is the point which comprises the pick-up feeding apparatus in the self-propelled roll baler which prevents stagnating of a molding material and clogging at the entrance part of a chamber.

As means for solving the above-described problems, in the present invention,
A conveyor device is installed in front of the entrance of the molding chamber of the bale molding device mounted on the machine body, and a pickup device having a width wider than the width of the conveyor device is installed in front of the front end of the conveyor device. A pickup grass collecting roller having a length substantially the same as the width of the pickup device and a laterally-fed spiral wing on the peripheral surface between the pickup device and the front end portion of the pickup device is provided. Aligned in parallel with the machine body, pivoted on the fuselage, and the feeding grass collecting roller is rotated from the pickup device side toward the front end of the conveyor device at the peripheral speed faster than the peripheral speed of the conveyor device. In connection with this, a pick-up feeding device in a self-propelled roll baler characterized by being driven to perform is proposed.
In the pick-up feeding device of the self-propelled roll baler, the rear surface of the feeding grass collecting roller is above the front end portion of the conveyor device, and has a diameter that is substantially the same as the width of the conveyor device and larger in diameter than the feeding grass collecting roller. The infeed pressure roller device formed in the shape of a roller is arranged and pivoted on the machine body, and the infeed pressure roller device is arranged at a peripheral speed substantially the same as the peripheral speed of the conveyor device, and the lower peripheral surface side is from the pickup device side. A self-propelled roll baler characterized in that it is driven to rotate toward the entrance of the molding chamber of the bale molding device, and further,
In the pick-up and feeding device for the self-propelled roll baler, pressing means for pressing the molding material conveyed by the conveyor device from above is arranged at a position located behind the feeding and pressing roller device and above the conveyor device. We propose a pick-up and feed device in a self-propelled roll baler characterized by being fixedly supported on the airframe,
In the pick-up and feeding device for the self-propelled roll baler, a support roller is provided at a portion located above the rear end portion of the conveyor device and a portion located above the rear end portion of the conveyor device above the rear portion of the feeding grass collecting roller. A belt formed on the support roller is stretched endlessly on these support rollers so that the width of the conveyor device is substantially the same as the width of the conveyor device. A self-propelled roll baler characterized in that it is driven to rotate and the molding material delivered to the conveyor device by the feeding grass collecting roller is sent to the molding chamber while being compressed in cooperation with the endless belt and the conveyor device. Presents a pick-up and feeding device.

  The means of the present invention picks up the material to be molded by a pickup device having a width wider than that of the conveyor device, and collects the material to the width of the conveyor device by a feeding grass collecting roller having spiral feed blades at both ends. Since the device can be handed over, a long molding material can be picked up without being collected and delivered to a narrow conveyor device. In addition, when the feeding pressure roller device is provided above the delivery portion, the molding material delivered from the pickup device to the conveyor device via the upper peripheral surface of the grass collecting roller is fed backward while being pressed from above. As a result, the molding material stagnating in the delivery section can be smoothly fed into the inlet of the bale molding apparatus.

  In addition, when a pressing means for pressing the material to be molded from above is installed above the conveyor device, the clogging of the material to be molded on the conveyor device is suppressed to cause clogging at the inlet of the bale molding device. And can be fed into the molding chamber.

This is a normal riding type self-propelled roll baler that is constructed by mounting the feeding device B in parallel in the front-rear direction and mounting a cabin 11 on which the driver enters on the left and right sides of the body 1. .

  As shown in FIG. 3, the roll bale forming apparatus 2 includes a plurality of guide wheels 22 that are arranged in an arc shape inside a machine body formed in a machine casing and are pivotally supported on the machine body, and inside the guide wheels 22, The tight chain 21 is rotated around the outer peripheral side of the guide wheel 22 arranged in parallel to the arc shape to the arc-shaped guide plate 23 which is arranged in a substantially concentric shape and fixedly supported on the airframe, and then is folded back to the inner peripheral side to guide The endless material is wound around the outer peripheral surface of the plate 23, and the space surrounded by the tight chain 21 that rotates on the inner peripheral side is defined as the molding chamber 20, and the molding material fed into the molding chamber 20 is rolled. The front a that is formed in a bale and has a normal configuration, and the inlet a for receiving the molding material of the molding chamber 20 is disposed between the upper sprocket 24 and the lower sprocket 25 that folds the tight chain 21 to the inner peripheral side. And over La FR, it is configured with a space formed between the lower sprocket 25.

  The pick-up and feeding device B includes a conveyor device b that is mounted on the front surface of the inlet a of the bale molding device 2 so as to have a width substantially corresponding to the opening width of the inlet a, and the front surface of the front end portion of the conveyor device b. It is constituted by a pickup device c arranged forward and mounted on the front end of the machine body 1 so that the molding material picked up by the pickup device c is transferred to the conveyor device b and fed into the inlet a of the molding chamber 20. The pick-up device c has the same width as the previous one, but the width D of the left and right, which is the working width thereof, is wider than the width d of the conveyor device b as shown in FIG. The left and right end portions protrude outward from the conveyor device b when viewed from the front.

  Further, the conveyor device b has its front end shortened by shortening its front and rear length, and the pickup provided at the front end of the conveyor device b and the front end of the machine body 1 as shown in FIG. A space W is formed between the rear edge of the device c. Within this interval W, the feeding grass collecting roller 3 having a length substantially the same as the width dimension of the pickup device c and having the spiral feed blades 30 of the transverse feed on the peripheral surfaces of both ends is provided with the pickup device c. It is coordinated in a state where it is parallel to the airframe 1 and is mounted on the airframe 1.

  Although this feeding grass collecting roller 3 is omitted in the drawing, its rotating shaft is conducted via an output shaft of a prime mover (not shown) mounted on the body 1 and a conduction mechanism (not shown), It is driven and rotated by the operation of the prime mover. The rotation is such that the upper peripheral surface side of the feeding grass collecting roller 3 is rotated from the side of the pickup device c located on the front surface toward the front end of the conveyor device b located on the rear surface, and the rotational speed is In this example, the peripheral speed is set to 4.49 m / s, which is several times faster than the peripheral speed 1.59 m / s of the conveyor device b.

  Further, the feeding grass collecting roller 3 has an axial length that is substantially the same as the left and right width dimensions of the pickup device c, and is arranged in parallel with the pickup device c so as to be mounted on the shaft. In the same manner as the pickup device c, the left and right end portions of the conveyor device b are axially supported so as to protrude outward from the left and right side edges of the conveyor device b. . The spiral feed blades 30 provided at both ends are provided on the peripheral surface of the portion projecting outward from the conveyor device b in the front view, and the center of the roller 3 positioned on the front surface of the front end portion of the conveyor device b. The part is provided with a lug-shaped protrusion 31 along the axial direction.

  Since the pick-up device in the self-propelled roll baler of this embodiment is formed wider than the conveyor device b by expanding the width of the pick-up device c to the left and right, a material to be molded having a long bowl length can be picked up. The molding material picked up by the pickup device c is collected at the center of the left and right widths by spiral feed blades 30 provided at both ends of the feeding grass collecting roller 3 arranged in parallel to the rear of the pickup device c. Since it is delivered to the conveyor device b by the peripheral surface of the feeding grass collecting roller 3 that rotates at a speed faster than the peripheral speed of the rotating belt of the conveyor device, to the delivery part between the pickup device c and the conveyor device b, It is delivered to the conveyor device b with a narrow width without causing stagnation.

  Next, FIG. 5 shows another embodiment. This embodiment is a modification of the above-described first embodiment. The width of the pickup device c provided on the front end side of the machine body 1 and the width of the feeding grass collecting roller 3 provided in parallel with the pickup device c are set in the machine body 1. This is an example in which the entire width of the airframe 1 including the cabin 11 to be mounted is widened.

Since the rest of the configuration except for this point is the same as that of the first embodiment, the same reference numerals are assigned to the same components and detailed description thereof is omitted.

  In this embodiment, since the width of the pick-up device c is approximately the same as the width of the machine body, the bale is picked up by the self-propelled roll baler and picked up the molding material that has been cut down on the field and left in a horizontal posture When performing the bale forming operation to form the material, it is possible to pick up the material to be molded without previously collecting the grass, collect the material to the width of the conveyor device b with the feeding grass collecting roller, and deliver it to the conveyor device b. It becomes possible to omit grass collection work.

  In addition, since the molding material can be picked up with the same width as the width of the aircraft, the molding material picked up in the next traveling process will not be stepped on with the traveling wheels of the aircraft, so Can reduce the mixing of pebbles.

  6 and 7 show still another embodiment. In this example, as in the first and second embodiments, the pickup device c is wider than the width of the conveyor device b, and the width of the pickup device c is increased between the pickup device c and the front end portion of the conveyor device b. The feeding grass collecting roller 3 having spiral feed blades 30 at both ends and having the same length as the pick-up device c arranged is pivotally supported and driven so that the upper peripheral surface is rotated rearward. A means that enables picking up of a long molding material and allows it to be transferred to the conveyor device b without causing a stagnation, causes the molding material to rise upward at the transfer portion, and causes a bulge. In order to eliminate the occurrence of clogging that is supported by the inlet a due to the increase in bulk when it is sent to the inlet a of the molding chamber 20 and into the molding chamber 20 by Feeding pressure roller device that is driven so that the lower peripheral surface side is rotated rearward at substantially the same speed as the belt of the conveyor device b at a position located above the front end portion of the conveyor device b above the grass collecting roller 3. 4 is a means for pivotally supporting 4.

  In the example shown in FIGS. 6 and 7, the feed pressing roller device 4 is located below the feed grass collecting roller 3 at a position above the front end of the conveyor device b and below the roller 4. The peripheral edge is positioned so as to be located slightly below the lower peripheral surface of the front roller FR that forms the upper edge of the inlet a of the molding chamber 20 of the bale molding apparatus 2, and is pivotally supported on the body 1 by the shaft s. Therefore, the shaft s is a motor (not shown) mounted on the machine body 1 so that the lower peripheral surface side of the roller 4 rotates from the front to the rear at substantially the same speed as the peripheral speed of the conveyor device b. Is conducted through an output shaft and a conduction mechanism (not shown).

  As shown in the plan view of FIG. 7, the infeed pressing roller device 4 is formed to have a width substantially the same as the width of the conveyor device b, and is positioned at the upper position of the front end portion of the conveyor device b and is pivoted. As shown in the side view of FIG. 6, the trunk peripheral surface is formed in an octagonal rectangular tube shape, and a pressing-in blade plate 40 that projects obliquely rearward from the ridge edge in the rotational direction has a shaft. It is provided in a rug shape along the direction, and is configured in a roll shape as a whole.

  The infeed pressing roller device 4 is fed to the front end portion of the conveyor device b while being grassed toward the center in the width direction by the infeed grass collecting roller 3, thereby increasing the volume of the molding material that rises. Acting to scrape backward while pressing against the upper surface of the front end portion of the conveyor device b, so as to compress the material to be molded up and down in cooperation with the conveyor device b and send it toward the inlet a of the molding chamber 20 Therefore, it is possible to prevent the molding material delivered to the conveyor device b while being collected by the feeding grass collecting roller 3 from being used by the inlet a of the molding chamber 20.

  Next, FIGS. 8 and 9 show still another embodiment. This embodiment is a modified example of the third embodiment in which the configuration of the feed pressing roller device 4 in the third embodiment shown in FIGS. 6 and 7 is changed.

  In this example, the feed pressing roller device 4 has the shaft s, which is the rotation shaft thereof, positioned at a height position above the front end portion of the conveyor device b and below the shaft of the front roller FR. The shaft support is the same as that of the infeed pressing roller device 4 of the above-described third embodiment, but the disk 41 is arranged in parallel without providing a square tube or a roll-shaped body having an appropriate shape on the shaft s. The feeding and collecting roller 3 is driven by driving the assembly so that the disks 41 arranged side by side are rotated rearward at a circumferential speed substantially the same speed as the rotating belt of the conveyor device b. The material to be molded that is fed to the upper surface of the front end portion of the conveyor device b is pressed against the upper surface of the conveyor device b, compressed, and sent backward.

  This embodiment means is the same as that of the above-described embodiment except for the configuration of the above-described feeding pressure roller device 4 except that the plurality of disks 41 are arranged in parallel. Since there is no change, the same components are denoted by the same reference numerals, and detailed description thereof is omitted.

  In this embodiment, the feeding material collecting roller 3 is configured to feed the molding material transferred to the front end portion of the narrow-width conveyor device b while receiving the grass into a roller shape by arranging the disks 41 in parallel. Since the pressing roller device 4 is compressed in cooperation with the conveyor device b so as to be directed to the inlet a of the molding chamber 20, the material to be molded can be used at the inlet a by operating in the same manner as in the third embodiment. Will come to prevent.

  10, 11 and 12 show still another embodiment. In this embodiment, the pressing means 5 that presses the material to be molded that has passed through the infeed pressing roller device 4 from above to the upper surface of the conveyor device b is compared with the infeed pressing roller device 4 with respect to the means in the above-described third and fourth embodiments. The configuration provided between the front roller FR is an added configuration mode. Since the rest of the configuration excluding the pressing means 5 is the same as that of the above-described embodiment, the same components are denoted by the same reference numerals and detailed description thereof is omitted.

  Therefore, the pressing means 5 is a length that crosses the conveyor device b in the left and right directions in a plan view at a height position that is substantially aligned with the axis s that is the rotation axis of the feeding pressure roller device 4 behind the feeding pressure roller device 4. The support rod 50 is arranged and both ends thereof are attached to and supported by the machine body 1, and a plurality of rod-like bodies 51 that protrude horizontally toward the lower edge of the front roller FR are provided on the support rod 50 as shown in FIG. The material to be molded is fed in parallel in a comb-teeth shape, so that the molding material fed from the upper side to the inlet a of the molding chamber 20 by the conveyor device b via the infeed pressing roller device 4 can be seen from above. The bulge of the molding material pressed and compressed by the pressing and feeding pressure roller device 4 is suppressed.

  The pressing means 5 can be held at the inlet a by being inflated again while the molding material pressed and compressed by the feeding press roller device 4 is conveyed to the inlet a of the molding chamber 20 by the conveyor device b. It is only necessary to prevent bulging again, and as shown in FIG. 12, it is formed on a plate 52 having a width substantially corresponding to the width of the conveyor device b, This may be configured to be fixedly mounted on the support rod 50 so as to protrude substantially horizontally toward the lower edge of the front roller FR.

  13 and 14 show still another embodiment. In this example, the pressure for suppressing the swelling generated in the molding material delivered to the conveyor device b by the feeding grass collecting roller 3 and the molding material generated while being fed to the inlet a of the molding chamber 20 by the conveyor device b. The belt conveyor device 6 is stretched in parallel with the conveyor device b between the upper end of the conveyor device b and the upper rear end portion of the conveyor device b so as to suppress the swelling again. This is an example of performing the above.

  In this example, the belt conveyor device 6 is not provided with the feeding press roller device 4 above the front end portion of the conveyor device b, and the belt conveyor device 6 is provided with an endless portion of the belt conveyor device 6 at a portion that supports the feeding press roller device 4. A support roller 61 that supports the belt 60 is pivotally supported, and the upper end of the rear end portion of the conveyor device b is driven by the shaft using the shaft of the front roller FR installed at that position. A rotating support roller 62 is pivotally supported, and an endless belt 60 formed with a width substantially equal to the width of the conveyor belt of the conveyor device b is wound around the support roller 61 and the support roller 62, The lower peripheral surface side is configured to be driven to rotate backward at a peripheral speed substantially the same as the peripheral speed of the conveyor device b.

  In this example, the material to be molded delivered by the feeding grass collecting roller 3 to the front end portion of the conveyor device b while being collected is a portion that rotates the support roller 61 of the endless belt 60 of the belt conveyor device 6. The front end portion of the conveyor device b facing this is compressed by receiving pressure and is held in a compressed state by the downward rotation side of the endless belt 60 and the transport surface of the conveyor device b facing this. Thus, the material is fed to the inlet a of the molding chamber 20, and the holding of the molding material generated at the inlet a is prevented accurately.
