Secondly, describe for administering as the action of the fan blower 27 of the wind pushing mechanism of fertilizer apparatus 22 and the fan blower control loop that stops.

In the past, have and the rice transplanter of planting the fertilizing and planting of the usefulness of applying fertilizer simultaneously is known.Fertilizer apparatus comprises the hopper that holds fertilizer, be configured in the hopper bottom and see off at every turn ormal weight delivering mechanism, utilize wind-force fertilizer to be transported to the Blast mechanism of fertilizer placement.

As the fan blower of wind pushing mechanism, utilize motor action, when piloting engine, move, be the mechanism that when the plantation operation, will be transported to fertilizer placement by the fertilizer that delivering mechanism is seen off from hopper by wind-force.This wind pushing mechanism, for example, when continuing seedling, owing to do not plant, so, there is no need fertilizer is transported to fertilizer placement, also there is no need to make the fan blower action.Therefore, be operated under the continuous locational situation of seedling as the main shift lever of speed change with operating mechanism that go, the technology of the action of the machine that turns off the blast is known (for example, opening flat 8-70663 communique with reference to the spy).

But continuous seedling operation is according to the size (reciprocal distance) in field, go situation about stopping the or continue situations such as situation of seedling operation, the length of activity duration cost, end at short notice sometimes sometimes by a plurality of people.As before; Main shift lever is made as continuous seedling position under the situation of the structure that the action of fan blower stops; Finish continuous seedling operation at short notice, begin to plant under the situation of operation once more soon; Need spended time for the rotating speed that makes fan blower returns to original rotating speed, have the deficiency in draught of fan blower, can not carry the situation of the fertilizer of ormal weight.On the other hand; Have the continuous seedling operation of landed end, under the situation of the operation of supply rice shoot on the auxiliary rice shoot platform bunch and the operation etc. of supply fertilizer in the hopper of fertilizer apparatus; Because the activity duration is elongated, so, fan blower is stopped; Can make the power consumption of battery few, noise is reduced.In addition, the interruption of plantation operation likewise also has the long weak point that has in the activity duration.

In view of above-mentioned problem, a kind of rice transplanter is provided, said rice transplanter makes Blast mechanism be in appropriate operating state according to the situations such as interruption of continuous seedling operation, plantation operation, and, can seek the saving electric power of wind pushing mechanism.

That is, liftably plantation portion is being connected in the rice transplanter in the portion of going, comprising: the speed change of going is used operating mechanism, and the said gear that goes can be operated at the multi-change speed operating position that comprises continuous seedling position; The variable speed operation position detecting mechanism, said variable speed operation position detecting mechanism is positioned at continuous seedling position to the said speed change of going with operating mechanism and detects; Fertilizer apparatus, said fertilizer apparatus have the hopper that holds fertilizer, be configured in the bottom of said hopper and see delivering mechanism and the Blast mechanism that the fertilizer of seeing off is transported to fertilizer placement of the fertilizer of ormal weight off at every turn; Selection operation mechanism, said selection operation mechanism are used for the operating state of the said Blast mechanism when the said speed change of going is operated into continuous seedling position with operating mechanism is chosen as a kind of state of halted state or low air quantity state; Transport condition testing agency, said transport condition testing agency detect rice transplanter and whether are in transport condition; Control device; Said control device is controlled the action of said Blast mechanism; Utilizing said variable speed operation position detecting mechanism to detect the said speed change of going when being operated into continuous seedling position or neutral position with operating mechanism; Perhaps utilize transport condition testing agency to detect and be in when going halted state, according to the selection of said selection mechanism, the state that makes said Blast mechanism be in halted state or move with low air quantity.

Through such formation, the operating state of the Blast mechanism of the fertilizer apparatus during as continuous seedling operation can select that halted state is selected on a ground or with the state of low air quantity action.Thereby the operator can select halted state or low air quantity according to the time of continuous seedling operation needs, under the situation of selecting halted state, can seek the saving electric power of Blast mechanism effectively.On the other hand, under the situation of the operating state of selecting low air quantity, under the state that fertilizer is seen off stop; When seeking the saving electric power of Blast mechanism; After continuous seedling operation, be accompanied by and return to the plantation operation, the fertilising operation is begun.That is, the situation in the time of can be according to continuous seedling operation makes Blast mechanism be in appropriate operating state, and can seek the saving electric power of Blast mechanism.

In addition; Be equipped with instrumentation to be operated into the timer structure in the elapsed time in the moment of continuous seedling position with operating mechanism from the said speed change of going; Said control device; Utilizing under the situation of said selection operation mechanism's selection with the state of low air quantity action,, be operated into the moment of continuous seedling position with operating mechanism from the said speed change of going according to the instrumentation result of said timer structure; When predefined first setting-up time of process is above, make said Blast mechanism become halted state from the operating state of low air quantity.

Through such formation, if continuous seedling operation finishes, then can promptly begin to plant operation once more in first setting-up time, when in first setting-up time, not finishing, can automatically Blast mechanism be altered to halted state from the operating state that hangs down air quantity.Thereby, Blast mechanism is invalidly moved, can seek to save electric power.In addition, owing to can utilize timer to set first setting-up time, so, can set the time arbitrarily for according to operator's operating speed or workload etc.

In addition; The lifting position testing agency of the position of the said plantation of detection portion is equipped with; Said control device judges whether the position of the plantation portion that is detected by said lifting position testing agency rises to more than the setting height; Rising to setting height when above, making said Blast mechanism be in the operating state of low air quantity.

Through such formation,, plantation portion is risen in order to continue the operation outside the seedling operation; When interrupting plantation, fertilising operation or under situation such as end, field rotation; Because reduce the air quantity of Blast mechanism, so, when seeking the saving electric power of Blast mechanism; After this operation, can promptly begin the operation of applying fertilizer once more.

In addition; Have instrumentation and be operated into the timer structure of the moment elapsed time of continuous seedling position from the said speed change of going with operating mechanism; Said control device is operated into the moment that continues the seedling position from the said speed change of going with operating mechanism, till predefined second setting-up time of process according to the instrumentation result of said timer structure; Do not change the operating state of said Blast mechanism; When said second setting-up time of process is above,, make Blast mechanism be in the operating state of halted state or low air quantity according to the selection of said selection mechanism.

Through such formation; When the speed change of going is operated into continuous seedling position with operating mechanism and when interrupting applying fertilizer operation; Even the delivering mechanism of fertilizer apparatus is stopped; Also can make Blast mechanism action till through second setting-up time, the residual fertilizer that reliably delivering mechanism is transported in the carrier pipe of fertilizer placement is discharged.Thereby, can get rid of carrier pipe by residual fertilizer possibility of jamming.

Below, utilize Fig. 9 to Figure 18, form of implementation is described.

Secondly, utilize Figure 10 that the control method of the fan blower 10 when continuing the seedling operation is described.

At first, whether control device 80 is positioned at continuous seedling position P3 for main shift lever 52 and judges (step S10).Here, when main shift lever 52 is operated into continuous seedling position, because microswitch 85 is switched to connection from disconnection, so control device 80 is judged as main shift lever 52 and is positioned at continuous seedling position P3.Control device 80 when microswitch 85 cuts off, is judged as main shift lever 52 not in continuous seedling position.

Control device 80 being judged as main shift lever 52 when not being in continuous seedling position P3, carries out the judgement of step S10 once more.

Be positioned at main shift lever 52 under the situation of continuous seedling position P3, whether control device 80 is for utilizing selector switch 77 to select halted state to judge (step S20).Utilizing selector switch 77 to select under the situation of halted state, control device 80 makes fan blower 27 stop (step S30).

Next, whether control device 80 is positioned at continuous seedling position P3 for main shift lever 52 is judged (step S35).Be positioned at main shift lever 52 under the situation of continuous seedling position P3, control device 80 carries out step S35 once more.In addition, not under the situation of continuous seedling position P3, control device 80 makes fan blower 27 with common air quantity action (step S36), carries out step S10 once more at main shift lever 52.

Through such formation, when main shift lever 52 was operated into continuous seedling position P3, control device 80 stopped fan blower 27.Whereby, can seek fan blower 27 effectively and save electric power, can reduce noise.

In addition; In step S20, under the situation of selector switch 77 non-selected halted states, promptly; Under the situation of selector switch 77 selections with the state of low air quantity action; Utilize timer 81 beginning main shift levers 52 to be in the instrumentation (step S40) of the time t of continuous seedling position P3, making the rotating speed of the motor of fan blower is low speed rotation, makes the air quantity of fan blower 27 be low air quantity (step S45).

Secondly, control device 80 judges whether main shift lever 52 is positioned at continuous seedling position P3 (step S50).Be not at main shift lever 52 under the situation of continuous seedling position P3, be judged as from continuous seedling operation and recover, make fan blower 27 return common air quantity (step S55), carry out the judgement of step S10 once more to the plantation operation.Be positioned at when main shift lever 52 under the situation of continuous seedling position P3, whether more than the first setting-up time T1, judge (step S60) for time t, time t than the short situation of the first setting-up time T1 under, control device 80 carries out the judgement of step S50 once more.

In addition, when being judged as time t at step S60 under the situation more than the first setting-up time T1, replacement timer 81 (step S70), control device 80 make fan blower 27 move to halted state (step S80).

Next, whether control device 80 is positioned at continuous seedling position P3 for main shift lever 52 is judged (step S85).Be positioned at main shift lever 52 under the situation of continuous seedling position P3, control device 80 carries out the processing of step S85 once more.In addition, be not at main shift lever 52 under the situation of continuous seedling position P3, control device 80 makes fan blower 27 with common air quantity action (step S86), carries out step S10 once more.

Through such formation, when main shift lever 52 is operated into continuous seedling position P3, during the first setting-up time T1, the speed setting of the motor of fan blower 27 is become low speed rotation, make fan blower 27 with low air quantity action.

And when during the first setting-up time T1, when main shift lever 52 was operated the position beyond the continuous seedling position P3, control device 80 was judged as and recovers the plantation operation, made the air quantity of fan blower 27 return to common air quantity action.In addition, through the first setting-up time T1, when also main shift lever 52 being maintained the state of continuous seedling position P3 operation, control device 80 makes fan blower 27 transfer to halted state.

Whereby, under the state that seeing off of fertilizer stopped, seeking fan blower 27 and save electric power, and, after continuous seedling operation, be accompanied by and recover the plantation operation, can promptly begin the operation of applying fertilizer once more.That is, the situation during according to continuous seedling operation makes fan blower 27 become appropriate operating state, and, can save the electric power of fan blower 27.

And in ends of job such as continuous seedlings, main shift lever 52 is operated under the situation of low-speed forward position P2 or shift position P5 from continuous seedling position P3, microswitch becomes disconnection, and fan blower 27 moves once more.

Whether control device 80 is judged above assigned position for the position (highly) of the plantation portion 40 that is detected by lifting position detecting sensor 82.Under the situation above the assigned position, control device 80 is judged as does not plant operation now, makes fan blower 27 be in the job state with low speed rotation in the position of plantation portion 40.

Through such formation,, when making 40 risings of plantation portion and interrupting the fertilising operation, when seeking fan blower saving electric power, after this operation, can promptly begin the operation of applying fertilizer once more in order to continue the operation beyond the seedling operation.

In addition, be operated at main shift lever 52 under the situation of continuous seedling position P3, also can be till through the second setting-up time T2 from this operation, making fan blower 27 is common air quantity.

For this reason, utilize Figure 11 and Figure 12, the control method of the fan blower 27 during for continuous seedling operation describes.In addition,, give identical Reference numeral in the accompanying drawings, omit its explanation for the part of carrying out the control identical with said form of implementation.
