Front view of the agricultural harvesting machine shown in FIG. The rear view of the agricultural harvesting machine shown in FIG. FIG. 2 is a side view showing an operation of the agricultural harvesting machine shown in FIG. 1 and showing a state where a container is loaded and raised to a height.

  Next, embodiments of the present invention will be described with reference to the drawings. 1 to 5, reference numeral 100 denotes an agricultural harvesting machine.

  As shown in FIG. 1, the agricultural harvesting machine 100 conveys a traveling device 110 that travels in the field G, a cutting unit 120 that harvests vegetables grown in the field G, and the harvested vegetables backward. And a container placement unit 140 for placing the container 200 that accommodates the transported vegetables and the like.

  The traveling device 110 is a pair of independently driven hydraulic pumps 113 and a hydrostatic transmission of a traveling motor 114 that are driven to rotate by an engine 112 mounted on an upper part of a portal frame 111 that is installed on the traveling device 110. The crawlers 115 and 115 are provided at the lower part, and the left and right crawlers 115 and 115 are straddled on one or several ridges of the field G to travel along the ridges. A cockpit 116 and a traveling handle 117 are installed on the upper side of the portal frame 111 of the traveling device 110 toward the front, and a control panel 118 is installed in front of the traveling handle 117. The control panel 118 is equipped with control devices and instruments for the engine 112. The engine 112 is disposed immediately after the cockpit 116 and at the center of the traveling device 110 in the front-rear direction and the left-right direction, that is, at the center of gravity of the traveling device 110.

  The cutting unit 120 cuts the vegetables 1 and the like cultivated in the field G, and is disposed in front of the traveling device 110 in the traveling direction. The cutting part 120 is supported so that the support frame 121 can move up and down via a support shaft (not shown) on the front part of the portal frame 111. At the front end of the support frame 121, a cutter unit 122 having a clipper blade 122A extending left and right is attached. In addition, a rotating shaft 124 </ b> A of the scraping roller 124 is rotatably supported in front of the support frame 121 via left and right attachments 123. Further, a guide member 125 extends forward from the left and right attachments 123.

  The support frame 121 includes a lower height adjustment roller 127 installed on the ground G1 via left and right attachments 126. The height adjustment roller 127 that is rotatable by the extension of the rod 128A of the hydraulic cylinder 128 is provided on the ground G1. Thus, the cutting height of the cutter part 122 can be set to a predetermined height. The height adjustment roller 127 can arbitrarily adjust the attachment angle of the attachment 126, and can thereby arbitrarily set the cutting height of the cutter unit 122. The hydraulic cylinder 128 is operated by a hydraulic pump driven by the engine 112.

  The function of the height adjusting roller 127 will be described in detail. The hydraulic cylinder 128 employs a float type hydraulic valve. That is, when the load applied to the height adjustment roller 127 due to the unevenness of the ground becomes larger than the set pressure with respect to the ground level preset by the height adjustment roller 127, the hydraulic pressure of the hydraulic cylinder 128 becomes larger than the set value. When the rod 128A of the hydraulic cylinder 128 is reduced so that the hydraulic pressure becomes equal to the set value, and the load applied to the height adjustment roller 127 becomes smaller than the set pressure, the hydraulic pressure in the hydraulic cylinder 128 becomes smaller than the set value, and the hydraulic pressure is reduced. The rod 128A of the hydraulic cylinder 128 extends so as to be equal to the set value. As a result, the cutting unit 120 automatically moves up and down following the ground level of the field G during the running operation, and in conjunction with this, the cutter unit 122 The clipper blade 122A also automatically moves up and down following the ground level of the field G. As a result, the height adjustment roller 127 absorbs the irregularities even if the ground has irregularities. As a result, the cutting height of the cutter unit 122 is always constant with respect to the ground level.

  The cutter unit 122 cuts the front vegetable 1 and the like with the upper and lower clipper blades 122A reciprocating left and right by the hydraulic motor 129, leaving the lower part of the vegetable 1 and the like, that is, the vicinity of the root. Are fed to the rear conveyance unit 130 by the rotation of the scraping roller 124. The scraping roller 124 is provided with a bar-shaped scraping member 124B that extends spirally symmetrically from the substantially central position in the width direction around the rotation shaft 124A, and the scraping roller 124 is rotated by the hydraulic motor 129. The cut vegetables 1 and the like are scraped toward the rear conveying unit 130 and sent. The guide member 125 is located at the front left and right ends of the scraping roller 124 and serves to guide the vegetables 1 and the like on the front ground G1 toward the cutter member 122 and the scraping roller 124.

  The transport unit 130 transports the vegetables 1 and the like cut by the cutter unit 122 to the rear container 200 by the hydraulic motor 133, and includes a front conveyor 131 and a rear conveyor 132. The front conveyor 131 is integrally disposed on the inner side of the support frame 121, and the front end is located in the vicinity of the cutter part 122 and the rear end is inside the front part of the portal frame 111 and at a low position above the crawler 115. Has been placed. The rear conveyor 132 is disposed below the engine 112, the front end is positioned at a low position inside the front part of the portal frame 111, the main body part passes obliquely upward inside the rear part, and the rear end is a gate type. It reaches the rear of the frame 111. And the vegetables 1 etc. which were cut | disconnected by the cutter part 122 are conveyed back on the front conveyor 131 and the rear conveyor 132, fall in the container 200 from the rear end of the rear conveyor 132, and come to be accommodated. Yes. The hydraulic motors 129 and 133 are driven by the engine 112.

  A fuel tank 171 and a hydraulic cylinder for the engine 112, a hydraulic cylinder, and a hydraulic pressure are disposed below the rear conveyor 132, that is, in a space S of the portal frame 111 surrounded by the upper surface of the crawler 115 and the lower surface of the rear conveyor 132, as shown in FIG. A hydraulic fluid tank 172 for a motor or the like is mounted. As shown in FIGS. 1 and 2, the fuel tank 171 and the hydraulic hydraulic oil tank 172 are arranged directly below the engine 112 and are located at the center in the front-rear direction of the traveling device 110. In FIG. 1, reference numeral 173 indicates a rearview mirror, and reference numeral 174 indicates a canopy.

  The container placement unit 140 is a unit that detachably places the container 200 that stores vegetables and the like that have been transported backward by the transport unit 130 and that is dropped, and the placement frame 141 that is located behind the portal frame 111 includes: It is suspended and supported at the rear part of the gate-type frame 111 via the tilting mechanism 150 and the lifting mechanism 160. The mounting frame 141 includes a vertical frame portion 142 that is in contact with the side surface of the container 200, and two horizontal forks 143 and 143 that extend horizontally from the lower portion of the vertical frame portion 142 along the ground G1. . The two horizontal forks 143 and 143 can be inserted into the insertion ports 201A and 201A of the two rows of insertion portions 201 and 201 provided on the lower surface of the container 200. Reference numeral 144 denotes a reinforcing material for the joint between the vertical support frame 151 and the horizontal member 152.

  The container mounting unit 140 can tilt the entire mounting frame 141 by a tilt mechanism (tilt mechanism) 150 by a predetermined angle (± 15 degrees with respect to the horizontal plane in the illustrated example). In the tilting mechanism 150, the vertical frame portion 142 is supported via a hinge 153 with respect to the horizontal member 152 fixed to the lower portion of the vertical support frame 151, and between the upper portion of the vertical frame portion 142 and the upper portion of the vertical support frame 151. A hydraulic cylinder 154 is interposed therebetween. Accordingly, the rod 154A of the hydraulic cylinder 154 is extended to tilt the entire mounting frame 141 downward, and the rod 154A of the hydraulic cylinder 154 is contracted to tilt the entire mounting frame 141 upward. The extension / reduction operation of the hydraulic cylinder 154 is enabled by a remote operation from an operator M seated on the cockpit 116.

  The container placement unit 140 can be moved up and down by the lifting mechanism 160 while maintaining the horizontal posture of the entire mounting frame 141. The elevating mechanism 160 includes a pair of left and right parallel link mechanisms. In the parallel link mechanism, two parallel upper and lower arms 162 and 162 are hinged between the vertical member 161 attached to the upper part of the portal frame 111 and the vertical support frame 151 of the tilting mechanism 150. The hydraulic cylinder 163 is interposed between the lower arm 162 and the lower part of the portal frame 111. A hood 164 is hinged to the rear part of the upper part of the portal frame 111. The food 164 serves to guide the vegetables 1 and the like on the rear conveyor 132 from the rear end to the upper surface opening of the container 200 so as to be accommodated in the container 200 without being affected by wind or the like. In the middle of the hood 164 and the lower arm 162, a link arm 165 that closes the hood 164 by rotating the arm 162 downward and opens the hood 164 by rotating the arm 162 upward is provided. Both ends are pin-coupled. The elevating mechanism 160 extends the rod 163A of the hydraulic cylinder 163 and stably raises the entire mounting frame 141 while maintaining its posture, and contracts the rod 163A of the hydraulic cylinder 163 to reduce the entire mounting frame 141. While maintaining this posture, it is lowered stably. The extension / reduction operation of the hydraulic cylinder 163 is enabled by a remote operation from the operator M seated on the cockpit 116.

  The container 200 is a large-sized container (for example, having an empty weight of 60 kg to 90 kg and about 300 kg when vegetables enter) that contains vegetables 1 and the like dropped from the rear end of the rear conveyor 132. Can be accommodated. Two rows of insertion portions 201 and 201 having insertion ports 201A and 201A into which two horizontal forks 143 and 143 are inserted are attached to the lower surface of the container 200.

  Next, a method for harvesting the vegetables 1 cultivated in the field G using the agricultural harvesting machine 100 having the above configuration will be described.

  First, a case will be described in which an empty container on the ground G1 in the field G is scooped up and placed, and a full container is lowered again on the ground G1.

  In this case, the engine 112 is started, and the rod 154A of the hydraulic cylinder 154 of the tilting mechanism 150 is extended by the remote operation from the operator M of the cockpit 116 with respect to the empty container 200 on the ground G1 in the field G. Then, the front ends of the horizontal forks 143 and 143 are tilted downward, and the harvesting machine 100 is moved backward. When the two horizontal forks 143 and 143 are inserted into the insertion ports 201A and 201A of the insertion portions 201 and 201 of the empty container 200, the rod 154A of the hydraulic cylinder 154 is contracted to make the horizontal forks 143 and 143 in a horizontal posture. The empty container 200 is lifted from the ground G1.

  Next, the harvesting machine 100 is moved to the start point in the field G, the rod 128A of the hydraulic cylinder 128 is extended, and the height adjusting roller 127 is grounded to the ground G1. Thereby, the cutting height of the cutter part 122 is adjusted according to the vegetables 1 etc. which were planted on the ground G1. Then, the cutting unit 120 and the conveyance unit 130 are started, and the harvesting work machine 100 is run at a low speed along the ridge from the start point.

  While the harvesting machine 100 is traveling at a low speed, the vegetable 1 planted in front of the basket is guided to the rear cutter unit 122 by the guide members 125, 125 located at the left and right ends of the head, and by the clipper blade 122A of the cutter unit 122 The vicinity of the base is cut, and the cut vegetables 1 and the like are sent onto the rear front conveyor 131 by the rotating scraping roller 124. The vegetables 1 and the like sent on the front conveyor 131 are further transported to the rear conveyor 132 and dropped into the container 200 from the rear end of the rear conveyor 132 and stored.

  During the operation by the harvesting machine 100, the vegetables accommodated in the container 200 may be unevenly distributed either forward or backward (for example, rearward). If the contained vegetables are unevenly distributed in the container 200, the running stability of the harvesting work machine 100 and eventually the harvesting work stability (such as the cutting stability of the cutter unit 122) are affected. Therefore, the tilting mechanism 150 is used and the rod 154A of the hydraulic cylinder 154 is repeatedly expanded and contracted by remote operation from the operator M, and the entire mounting frame 141 is repeatedly moved up and down by a predetermined angle (for example, within a range of ± 10 degrees). To eliminate the uneven distribution of vegetables contained in the container 200. In this way, the harvesting operation is continued until the inside of the container 200 is full.

  When the container 200 is filled with the harvested vegetables 1, the container 200 is lowered to an appropriate place. The tips of the horizontal forks 143 and 143 are tilted downward to ground the container 200 on the ground G1, and the harvesting work machine 100 is moved forward to extract the horizontal forks 143 and 143 from the insertion portions 201 and 201 of the container 200. Then, the horizontal forms 143 and 143 are inserted into the insertion portions 201 and 201 again with respect to the empty container 200, the empty container 200 is lifted, and the process returns to the next harvesting operation. Thereby, a continuous harvesting operation is possible.

  Next, a description will be given of a case where an empty container on the carrier platform is placed and the full container is loaded again on the carrier platform.

  In this case, the engine 112 is started, and the lifting mechanism 160 is operated by the remote operation from the operator M on the empty container 200 on the platform of the transport vehicle, and the horizontal forks 143 and 143 are raised to the loading height. Specifically, by extending the rod 163A of the hydraulic cylinder 163, the vertical support frame 151 suspended and supported by the upper and lower arms 162 and 162 is raised, and the mounting frame 141 supported by the vertical support frame 151 is in a horizontal posture. The horizontal forks 143 and 143 are raised to the loading height of the container 200. In conjunction with the rising of the mounting frame 141, the hood 164 above the container 200 opens greatly, and interference with the container 200 is avoided when the container 200 is lifted.

  Then, while retracting the harvesting machine 100, the tip of the horizontal forks 143, 143 is tilted downward by the operation of the tilt mechanism 150, and the horizontal forks 143, 143 are inserted into the outlets 201A, 201A of the empty container 200 on the loading platform. Plug in. Next, the horizontal forks 143 and 143 are returned to the horizontal posture, the container 200 is lifted, the harvesting work machine 100 is advanced, and the empty container 200 is lowered to a predetermined height by the operation of the lifting mechanism 160. Finally, the harvesting machine 100 is moved to the start point in the field G.

  After that, as described above, the harvesting machine 100 is run at a low speed along the ridge from the starting point, and the harvesting operation is continued until the container 200 is filled with the vegetables 1.

  When the container 200 is filled with vegetables 1, the container 200 is moved to the loading place on the transport vehicle and loaded on the loading platform of the transport vehicle as it is. That is, by the remote operation of the operator M, as shown in FIG. 5, the elevating mechanism 160, specifically, the rod 163A of the hydraulic cylinder 163 is extended to raise the mounting frame 141 to the loading height in the horizontal posture. The harvesting machine 100 is moved backward with respect to the carrier platform of the transport vehicle laid horizontally. Then, the tip of the horizontal forks 143, 143 is tilted downward by the operation of the tilting mechanism 150, the container 200 is grounded to the loading platform of the transport vehicle, the harvesting machine 100 is advanced, and the horizontal forks 143, 143 are moved to the container 200. Are removed from the insertion ports 201A and 201A, and the container 200 is lowered onto the loading platform. In this way, the container 200 can be loaded directly.

  Note that the vegetables 1 in the container 200 loaded in the transporter are transported together with the container 200 to a vegetable factory or the like. An empty container 200 is brought into the field G again from the vegetable factory or the like.

  According to the harvesting machine 100 of the present embodiment, the following effects can be obtained.

(1) Since the container placement unit 140 for placing the large container 200 is provided behind the transport unit 130, a large amount of vegetables 1 and the like can be accommodated at a time, and the harvesting efficiency of the vegetables 1 and the like is improved.

(2) By adopting the tilting mechanism 150, the operator M on the harvesting work machine 100 can be easily placed alone behind the transport unit 130 by the remote operation by the operator M alone on the ground G 1. became. In addition, when there is uneven distribution of the vegetables contained in the container 200 during the harvesting operation, the tilting mechanism 150 can be operated to cancel the uneven distribution state. Thereby, the posture of the harvesting machine 100 can be stabilized, and the harvesting work can be performed stably.

(3) Since the lifting mechanism 160 and the tilting mechanism 150 allow the operator M on the harvesting work machine 100 to be alone by a remote operation, the large container 200 can be loaded directly onto the loading platform of the transport vehicle. The labor of loading the heavy container 200 on the carrier bed has been greatly reduced. In addition, a truck equipped with a forklift or crane, which is an attachment of a tractor waiting in the field, is no longer necessary, and labor saving of mechanical equipment can be achieved.
(4) Since the engine 112 is disposed on the upper side and the fuel tank 171 and the hydraulic fluid tank 172 are disposed on the lower side with the conveyance unit 130 at a lower position in between, the balance and stability when the harvesting work machine 100 is traveling are stable. Improved.

(5) In particular, since the upper engine 112, the lower fuel tank 171 and the hydraulic fluid tank 172 are arranged at substantially the center in the front-rear direction of the entire harvesting work machine 100, the front-rear balance of the harvesting work machine 100 is improved. Further, the traveling stability of the harvesting machine 100 is further improved, and the harvesting work of the vegetables 1 and the like is performed stably and efficiently in combination with the action of the height position adjusting roller 127 and the tilting mechanism 150 (the effect of eliminating the uneven distribution in the container 200). Can be done.
(6) As a result of mounting the engine 112 on the upper part of the portal frame 111, it is possible to minimize the influence of exhaust gas and exhaust heat from the engine 112 on the vegetables 1 and the like conveyed on the conveyance unit 130 at a low position. In addition to maintaining the freshness of the harvested vegetables 1 and the like, the maintainability of the engine 112 is improved, the failure of the engine 112 due to dust and mud adhering to the vegetables 1 and the like is eliminated, Merits such as being able to suppress deterioration (when the material is resin) were born.
