Loading stage 51a of the frame 52 relative to the loading stage 51b support front side of rear side, and with the layered laminate of loading part 50 State and unfolded state change posture.That is, frame 52 changes posture with the laminated arrangement of loading part 50 and unfolded state.It is specific and Speech, frame 52 are installed on the loading stage 52b of rear side and can be centered on the first fulcrums (fixed pivot) 521 fixed by position It is rotated towards front-rear direction, and is installed on the loading stage 51a of front side and (can be moved with the second fulcrum moved along the longitudinal direction Activity supporting point) it rotates centered on 522.

In addition, frame 52 has under the unfolded state of loading part 50 from curved shape upward halfway.In this way, The unfolded state lower frame 52 of loading part 50 is bent upwards, and thus, it is possible to improve the rigidity of frame 52.From the bending of frame 52 The part that front end is played in portion becomes the abutting part 523 abutted with aftermentioned mobile assisted parts 53.

Loading part 50 in the lamination state, will be loaded into the operation goods and materials (such as pad seedling, bag with fertilizer) of loading stage 51a, 51b It is fixed on the bottom surface 512 of loading stage 51a, 51b.In addition, loading part 50 is in the deployed state, releasing be loaded into loading stage 51a, The fixation of the operation goods and materials of 51b.Here, the fixation of operation goods and materials refer to operation goods and materials become cannot on loading stage 51 (51a) Mobile state is the state that operation goods and materials are steadily loaded on loading stage 51 (51a).The releasing fixation of operation goods and materials is Refer to the state that operation goods and materials can move on loading stage 51 (51a).In addition, in order on the bottom surface of loading stage 51a, 51b 512 Operation goods and materials can be carried out releasing fixed and less important work goods and materials the movements to expansion direction, loading part 50 has movement Assisted parts 53.

The mobile setting of assisted parts 53 is in the bottom surface 512 of loading stage 51 (such as loading stage 51a of front side).Mobile assisted parts 53 Has the roller 531 of multiple (such as 2) for arranging in left-right direction as mobile accessory.For each roller 531, rotary shaft The direction of 531a is set as orthogonal with the conveyance direction of operation goods and materials (expansion direction of loading part 50, such as front-rear direction), and It is arranged in the bottom surface of loading stage 51 512.In this way, by the way that roller 531 is arranged in the bottom surface of loading stage 51 512, in operation goods and materials In the case where mobile on the bottom surface of loading stage 51 512, movement (conveying) load reduction of operation goods and materials realizes operation goods and materials energy Enough round and smooth movements.In addition, multiple rollers 531 are linked by the connection shaft 532 parallel with rotary shaft 531a.

In addition, mobile assisted parts 53 has protruding portion 533, it is provided in the left and right end portions of connection shaft 532 above-mentioned The end (left part) of the side of frame 52, is protrusively provided to the side of loading stage 51.It is provided with and is loading in protruding portion 533 The abutting part for becoming mobile 53 side of assisted parts in the case where being abutted under the unfolded state in portion 50 with the abutting part 523 of frame 52 Abutment roller 533a.In addition, protruding portion 533 is formed as crank-like, configured outward from the extended line of connection shaft 532.

As shown in Fig. 1 (b), roller 531 under the laminated arrangement of loading part 50 to the bottom surface 512 than loading stage 51 more on the lower It is mobile.In addition, roller 531 is under the unfolded state of loading part 50 to the movement closer to the top of bottom surface 512 than loading stage 51.It is specific and Speech, roller 531 are located at more more rearward than frame 52 under the laminated arrangement of loading part 50.In this case, abutment roller 533a is from frame The abutting part 523 of frame 52 leaves, therefore roller 531 becomes to the state sunk to more on the lower than bottom surface 512.In addition, in loading part Under 50 unfolded state, roller 531 is located at the top of frame 52, and abutment roller 533a is abutted with the abutting part 523 of frame 52, from forming For the state boosted.Thereby, it is possible to so that roller 531 is automatically worked when the loading part 50 for keeping operation goods and materials mobile is unfolded. That is, roller 531 can be made automatically to work if necessary.

Thus much, have the roller of mobile auxiliary in loading stage, and roller is prominent under the loading condition of loading part, it is difficult So that operation goods and materials on loading stage stablize, but as described above, make roller 531 become intake type, then can be in the dress of loading part 50 Under load state on loading stage 51 (51a) fixed operation goods and materials.On the other hand, do not have the roller of mobile auxiliary in loading stage Words, have that the moving portion of the operation goods and materials under the unfolded state of loading part is not round and smooth, but as described above, by making roller 531 become intake type, prominent from the bottom surface 512 of loading stage 51 (51a) in the unfolded state lower roll 531 of loading part 50, therefore make Industry goods and materials are unstable on loading stage 51 (51a), can carry out releasing fixation to operation goods and materials.

In addition, roller 531 is not prominent from the bottom surface of loading stage 51 512, therefore does not act under the laminated arrangement of loading part 50 In operation goods and materials.Thereby, it is possible to stablize operation goods and materials in bottom surface 512 by the self weight for the operation goods and materials for being loaded into loading stage 51 On.That is, operation goods and materials can be fixed on bottom surface 512.

In addition, as shown in Fig. 1 (b), the configuration of roller 531 in the front apart from existing roller predetermined distance d, by with it is existing Roller collaborates, and will continuously act on the operation goods and materials moved on loading stage 51.In addition, roller 531 is preferably configured in existing roller 250mm or so front.

In addition, for mobile assisted parts 53, as mobile accessory, instead of roller 531, for example, it is also possible to be configured to The sliding pin for having the expansion direction extension along loading part 50.Even sliding pin, it also is similarly intake type with roller 531, is being filled Load portion 50 projects on the bottom surface 512 of loading stage 51 when being unfolded.

According to above-mentioned loading part 50, under the laminated arrangement of loading part 50, operation goods and materials are fixed on loading stage 51 (51a), therefore can prevent operation goods and materials from sliding from loading stage 51 (51a) body is in operation.In addition, in loading part Under 50 unfolded state, operation goods and materials are released from fixation, so the loading of operation goods and materials becomes good.That is, operation can be made Property improve.

In addition, can make to be released from fixed operation object under the unfolded state of loading part 50 by mobile assisted parts 53 Money sleekly moves on loading stage 51, and the loading of operation goods and materials becomes more preferable.In addition, being filled by mobile assisted parts 53 Under the laminated arrangement in load portion 50, operation goods and materials are fixed on loading stage 51 (51a), therefore can prevent body is in operation Operation goods and materials slide from loading stage 51 (51a), so operation goods and materials are released from solid under the unfolded state of loading stage 51 (51a) It is fixed, therefore the loading of operation goods and materials becomes good.That is, workability can be made to improve.

It is moved more on the lower in addition, moving assisted parts 53 in the lamination state to the bottom surface 512 than loading stage 51 (51a), Thus operation goods and materials are stablized because of self weight on loading stage 51 (51a), move assisted parts 53 in the deployed state to than loading stage The movement closer to the top of bottom surface 512 of 51 (51a), to be clipped in the shifting for carrying out less important work goods and materials between bottom surface 512 and operation goods and materials It is dynamic.It can prevent operation goods and materials from sliding from loading stage 51 (51a) in the lamination state as a result, in the deployed state operation goods and materials Loading become good.

In addition, mobile assisted parts 53 utilize with laminated arrangement and the frame 52 of unfolded state progress posture change and relative to The bottom surface 512 of loading stage 51 (51a) is free to advance or retreat, therefore can make mobile assisted parts according to the state of loading part 50 and reliably 53 work.

In addition, there is the case where setting power-assisted portion in above-mentioned loading part 50, stacking can be being changed into from unfolded state In the case where state, the power-assisted portion is by the loading stage 51a of front side to the position of laminated arrangement i.e. towards the loading stage 51b's of rear side Top pulls.Power-assisted portion is configured to for example by spring members by the of the frame 52 of the half-way of the frame 52 of front side and rear side It is connected between one fulcrum (fixed pivot) 521.For spring members, in the case where loading part 50 is unfolded state, along frame 52 Length direction elongation, to help the loading stage 51a for carrying out mobile front side in such a way that loading part 50 becomes laminated arrangement Power.
