Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a riding rice transplanter provided with a chemical spraying device on a reserve seedling stage.
[0002]
[Prior art]
Conventionally, planting seedlings grown in a seedling box on a field with a rice transplanter is a modern mechanized seedling planting farming method.
[0003]
In this case, as a method of spraying the main pests that occur before heading, a method of controlling the pests that occur after transplanting by spraying a osmotic transfer agent on the nursery box just before planting rice was used. .
[0004]
Moreover, recently, a mixed agent that simultaneously prevents pests and the like occurring after the middle stage of rice cultivation, which was not targeted by the box application agent, that is, a long-lasting box application agent has appeared.
[0005]
However, this long-lasting residual box application agent must be carefully applied to the seedling mat stored in the nursery box just before rice planting so that it is not evenly distributed. The operation of spraying on the surface was very time-consuming and troublesome.
[0006]
[Problems to be solved by the invention]
For this reason, it is also conceivable to install a medicine spraying device above the seedling stage of the riding rice transplanter so that the medicine can be sprayed while planting.
[0007]
However, since the above-mentioned medicine spraying device sprays the medicine from the upper part of the seedling platform toward the seedling mat, it is necessary to mount the drug spraying device on the planting part of the riding rice transplanter, particularly on the seedling platform. The planting part structure becomes complicated, the overall weight of the planting part increases, and the overall weight balance of the riding rice transplanter may become unbalanced, which may hinder the planting operation. Since the platform is tilted, when spraying the drug from above, there is a disadvantage that it is difficult to spray the drug evenly on the seedling mat, and the seedling platform has a backward tilt. Especially, in the case of a riding rice transplanter where the planting part is located at the lower end of the seedling stand and behind the traveling part, it is difficult to see the state of drug spraying from the driver's seat at the time of planting work, and accurate spraying work can be performed. There was a risk of difficulty.
[0008]

The present invention provides a riding rice transplanter provided with a chemical spraying device on a preliminary seedling stage, wherein the preliminary seedling stage is provided with a chemical spraying device and sprays the drug on a seedling mat of the preliminary seedling stage. It is something to be done.
[0009]
The medicine spraying device is also characterized by comprising a medicine storage hopper, a delivery mechanism section for delivering the medicine, and a self-running mechanism section that travels on the spare seedling stage.
[0010]
Further, the present invention is characterized in that a seedling mat detection sensor is provided on the seedling mat mounting surface of the preliminary seedling mounting stand so that the medicine spraying device can be started by detecting the seedling mat by the sensor.
[0011]

The feeding mechanism part m is made to substantially match the width of the seedling mat a of the preliminary seedling stage 44, and as shown in FIG. 4, a box-like hopper 45 having a tapered lower part and a lower tapered part of the hopper 45 The feed roller 52 is disposed below the feed roller 52, and the medicine discharge cylinder 53 communicates below the feed roller 52.
[0031]
The hopper 45, the feeding roller 52 formed with a large number of dimples into which drug particles are inserted and the drug discharge cylinder 53 are configured to have substantially the same width as the width of the seedling mat a of the preliminary seedling stage 44. It is arranged in a straddling state.
[0032]
In addition, the medicine discharge cylinder 53 extends to a position substantially in the middle of the plant height of the seedling mat a, and is laid between the left and right traveling machine side plates 50 and 50 in front of the medicine discharge cylinder 53 in the direction of medicine dispersion. A resistance rod 54 is disposed, and when spraying the medicine from the medicine discharge cylinder 53, the seedling leaves b in front of the medicine discharge cylinder 53 are weeded, and the spray medicine c does not interfere with the seedling leaves b and directly on the seedling mat a It can be sprayed.
[0033]
Further, as shown in FIG. 3, the roller shaft 55 of the feeding roller 52 protrudes left and right from the left and right traveling machine side plates 50 and 50, and left and right pulleys 56 and 56 are provided at both ends thereof. Moreover, a wheel shaft 57 is mounted on the traveling machine side plates 50 and 50 above the left and right front and rear guide wheels 51 and 51 loosely fitted to the left and right guide rails 49 and 49 having a substantially C-shaped cross section. The left and right pulleys 56, 56 at both ends of the roller shaft 55 and the left and right axle pulleys 58, 58 attached to the left and right wheel shafts 57 are respectively connected to the left and right interlocking belts 59. , 59 linked together.
[0034]
Moreover, traveling wheels 61 and 61 are provided at the inner ends of the left and right wheel shafts 57, and the traveling wheels 61 and 61 are configured to travel on the left and right ribs 48 of the preliminary seedling stage 44. .
[0035]
Accordingly, the traveling operation of the left and right traveling wheels 61, 61 and the rotation operation of the feeding roller 52 are the left and right axle pulleys 58, 58, the left and right interlocking belts 59, 59, and the left and right pulleys 56 of the roller shaft 55 of the feeding roller 52, By linking with 56, it is configured to synchronize while being timed.
[0036]
Furthermore, one of the left and right wheel shafts 57 on which the left and right axle pulleys 58 and 58 are pivoted is connected to the output shaft of the electric motor 60 attached to the traveling machine side plate 50, and is fed out by the action of the electric motor 60. While the mechanism part m is self-propelled, it is timed to self-propelled and the medicine feeding action by the feeding roller 52 is performed, and the self-propelling mechanism part B is configured by this configuration.
[0037]
The guide rails 49 and 49 and the front and rear guide wheels 51 and 51 having a substantially C-shaped cross section provided on the ribs 48 and 48 at the left and right end edges of the preliminary seedling mount 44 are arranged on the ribs 48 and 48 by the traveling wheels 61 and 61, respectively. It functions to guide the running of the vehicle stably.
[0038]
As shown in FIG. 4, the front and rear ends of the guide rails 49 attached to the ribs 48 of the preliminary seedling table 44 or the front and rear ends of the ribs 48 on which the traveling wheels 61 travel are used to stop the traveling of the feeding mechanism portion m. Stop limit switches 62 are provided, and are configured to automatically stop when the feeding mechanism part m reaches the front and rear end positions of the seedling mat a.
[0039]
The above-mentioned medicine spraying device M is provided in each of the preliminary seedling mounting tables 44 which are stacked with a certain number of intervals, and in particular, the uppermost chemical spraying device M of the preliminary seedling mounting table 44 is located above. Since there is nothing to cover, the medicine c flows out due to wind and rain. Therefore, a canopy 63 having a substantially inverted L-shaped cross section is provided so as to cover the inner side surface and the ceiling portion of the preliminary seedling stage 44, and the side of the preliminary seedling stage 44 is provided. The canopy 63 is pivotally supported by the support mounting part 64 of the spare seedling stage 44 and is attached to the inner side of the machine body so as to be opened and closed.
[0040]
Furthermore, as shown in FIG. 2, seedling mat detection sensors 46 are provided in the front, rear, left, right, and center portions on the placement surface of the preliminary seedling mounting table 44, and a plurality of seedling mat detection sensors 46 are used in this way. This prevents misdetection and prevents the spraying from starting even if the start switch 62 of the medicine spraying device M is turned on unless the seedling mat a on the preliminary seedling table 44 is detected by the sensor 46. .
[0041]
In addition, the seedling mat detection sensor 46 is provided on each of the spare seedling mounts 44, and each spare mat is detected for the first time when it is detected that all the seedling mats a are placed on the preliminary seedling mounts 44 in all stages. All of the medicine spraying devices M on the seedling table 44 are operated at the same time so that the medicine is sprayed on the whole seedling mat a.
[0042]
As described above, since the chemical spraying is automatically performed only when the state that the seedling mat a is fully loaded on the spare seedling mount 44 is detected, it is possible to prevent malfunction and forgetting to spray.
[0043]
When the seedling mat detection sensor 46 is configured as described above, the seedling mat a is not loaded on all stages on the preliminary seedling mounting stage 44 in the final process of seedling planting, that is, the seedlings that remain after planting. There is a case where there is a mat a. In such a case, the seedling mat detection sensor 46 naturally does not detect all the seedling mats a, so that all the chemical spraying devices M are not operated. Therefore, only the medicine spraying device M on the spare seedling mount 44 on which the seedling mat a which is not planted is loaded can be manually operated.
[0044]
That is, when the medicine spraying device M is manually run along the left and right ribs 48, 48, the left and right running wheels 61, 61 placed on the ribs 48, 48 slide along the left and right ribs 48, 48. Then, as the traveling wheels 61 and 61 rotate, the feeding roller 52 of the feeding mechanism section m is also rotated through an interlocking mechanism such as a pulley and a belt, so that the medicine c can be sprayed.
[0045]
In addition, a one-way clutch is interposed between the feeding roller 52 and the roller shaft 55, and when the feeding mechanism unit m performs the spray running, the rotation of the roller shaft 55 is transmitted to the feeding roller 52. The medicine c can be delivered, but when the delivery mechanism part m travels backward to the original position after the medicine spray travels, the reverse rotation operation of the roller shaft 55 is not transmitted to the delivery roller 52 by the one-way clutch. The delivery of the medicine c remains stopped.
[0046]
The embodiment of the present invention is configured as described above, and when spraying the medicine onto the seedling mat a, each preliminary seedling placement of the riding rice transplanter A is passed in advance from the seedling box over the seedling mat a. It is loaded on the base 44.
[0047]
In the medicine spraying by the medicine spraying device M, first, the electric motor 60 of the medicine spraying device M is started to rotate one traveling wheel 61 of the left and right traveling wheels 61, 61, and the medicine spraying device M is started to travel. The interlocking belt 59 is rotated via one axle pulley 58 provided on the shaft of one traveling wheel 61, and the power is transmitted from one pulley 56 suspended on the belt 59 to the roller shaft 55 to feed the roller. 52 is rotated, the medicine c is fed downward from the hopper 45, and sprayed from the medicine discharge cylinder 53 toward the seedling mat a.
[0048]
At this time, since the resistance rod 54 weeds the seedling leaves b of the seedling mat a in the forward direction of the medicine discharge cylinder 53, the medicine c from the discharge cylinder 53 is accurately and quickly spread on the seedling mat a. It is possible to obtain a medicinal effect.
[0049]
And when returning the chemical spraying device M that has traveled to the end of the seedling mat a to the original starting position, the electric motor 60 is rotated in reverse or manually. At this time, the roller shaft 55 and the feeding roller 52 are Since it is linked by the one-way clutch, the feeding roller 52 does not rotate during reverse running, and the medicine c is not discharged.
[0050]
In addition, since most of the seedling mats a on each of the spare seedling stands 44 are lost before the planting is completed and only the seedling mats a are left to be planted, the medicine spraying device M does not operate. The medicine spraying device M is run along the guide rails 49 and 49, and the feeding roller 52 of the feeding mechanism section m is operated to spray the medicine.
[0051]

Furthermore, since the weight is applied to the front part of the riding rice transplanter, the overall weight balance is also improved. Since the drug can be sprayed as uniformly as possible to the seedling mat, the drug efficacy can be uniformly applied to the transplanted seedlings, and furthermore, since the drug spraying device is installed on the reserve seedling stand that is easy to see from the driver's seat, It is possible to visually check the state of drug distribution, and to perform an accurate drug distribution.
[0052]
Furthermore, since the seedling mat can be transferred from the cocoon to the spare seedling stage and the medicine can be sprayed, it is not necessary to spray the medicine on the nursery box in a separate place immediately before the rice planting work. There is an effect that sterilization can save labor.
[0053]
