Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a strawberry planter for planting swarded seedlings of strawberries in a field.

[0002]

2. Description of the Related Art Conventionally, in a strawberry transplanter as described above, for example, as disclosed in Japanese Patent Laid-Open No. 6-141626, strawberry seedlings are divided into individual plants,
The seedlings are packed and placed in a vertical position on the seedling stand, and pressed by the seedling pusher equipped on the seedling stand so that the weight of the seedling stand can be lowered from the upper side of the seedling stand toward the lower seedling outlet. Then, while keeping it dense, the vertical feed mechanism equipped on the lower surface of the seedling placing table intermittently vertically feeds it toward the seedling take-out opening at a predetermined pitch (for one strawberries seedling), thereby planting. The mechanism was used to suppress the inconvenience of missing plants when picking strawberries from the seedling take-out stand one by one from the seedling take-out port and planting them in the field.

[0003]

However, the strawberry transplanter based on the above-mentioned prior art is to stuff and place the strawberry plant seedlings, which are divided into individual plants, on the seedling placing table in a state in which they are vertically aligned. Therefore, depending on the packing condition (packing density, etc.), the seedling interval of strawberries may change. In such a case, the seedling interval of the strawberries seedlings placed on the seedling placing table and the vertical feed amount of the strawberries seedlings for one time by the preset vertical feeding mechanism do not match, and the strawberries seedlings are planted by the planting mechanism. There was a risk of missing stocks and overstocking when planting. In addition, even if the interval between the seedlings of the strawberries seedlings placed on the seedling placing table and the vertical feed amount of one time of the seedlings of the strawberries seedlings set by the preset vertical feed mechanism match, the vertical feed mechanism feeds the seedlings of the strawberries seedlings vertically. When an abnormal condition occurs in the plant, there is a risk that a plant stall or over-planting may occur during planting of the strawberries.
Moreover, in the strawberry transplanter based on the above-mentioned conventional technique, since no means for detecting the vertical feed abnormality of the strawberry seedling by the vertical feed mechanism is taken, the seedling interval of the strawberry seedlings placed on the seedling placing table and Even if there is a lack of stock or overstocking when planting the strawberries by the planting mechanism due to the discrepancy with the vertical feed of the strawberries by the vertical feeding mechanism, the worker should keep the condition of the field after the planting work. The situation could not be recognized unless the eyes were carefully observed, and the planting work was to be continued under the condition that stockouts and overstocks occurred. In other words, in order to recognize and eliminate inconveniences such as missing or over-straining in the strawberry planting machine based on the above-mentioned conventional technology in an early stage, the worker does the planting work while performing the planting work immediately after planting by the planting mechanism. It was necessary to frequently and carefully check the condition of the plant, and the planting work was troublesome.

[0004] Therefore, the strawberry plant transplanter based on the above-mentioned conventional technique is to stuff and place the strawberry plant seedlings, which are divided into individual plants, in a state of being vertically aligned on the seedling platform. It is also possible to take measures to detect whether the vertical feed mechanism has an abnormal vertical feed by determining whether or not the interval between the seedlings of straw grass seedlings placed on the table and the vertical feed amount by the vertical feed mechanism match. However, since the strawberries on the seedling stand are packed and placed in a dense state, and because the strawberries seedlings are placed on the seedling stand, the spacing between seedlings changes. , It was difficult to obtain a structure for detecting the vertical feed abnormality of the vertical feed mechanism by determining whether or not the seedling interval and the vertical feed amount of the strawberries by the vertical feed mechanism match.

An object of the present invention is to make it easy to obtain a structure for detecting an abnormal vertical feeding of strawberries by a vertical feeding mechanism without complicating the structure, thereby reducing the labor of an operator. The purpose is to be able to easily recognize or eliminate inconveniences such as stocks and overstocks early or in advance.

[0006]

In order to achieve the above-mentioned object, in the invention according to claim 1 of the present invention, strawberries are provided in a plurality of seedling pots that are partitioned and formed in a state of being vertically and horizontally aligned at a predetermined interval. A longitudinal feed mechanism for intermittently longitudinally feeding a mat-like seedling formed by inserting seedlings one by one at a predetermined pitch, and a detection means for detecting the presence or absence of the seedling pot passing with the longitudinal feeding of the mat-like seedling. And a detection unit that detects the vertical feed state of the mat-shaped seedlings by the vertical feed mechanism based on the detection information from the detection unit.

According to the first aspect of the present invention, the strawberries are vertically fed by the vertical feeding mechanism, and the strawberries are placed in a plurality of seedling pots that are compartmentalized in a state of being vertically and horizontally aligned at predetermined intervals. Since the mat-shaped seedlings are formed by inserting each of them, the strawberry seedlings, which are divided into individual plants, are packed according to their packing condition (packing density, etc.) The seedling interval does not change. In other words, due to the change in the seedling interval of the strawberries seedlings, the seedling spacing of the strawberries seedlings placed on the seedling mounting table and the vertical feed amount of one batch of the strawberries seedlings set by the preset vertical feeding mechanism do not match, and the planting This makes it possible to eliminate the inconvenience of missing or over-planting when planting strawberries by the attachment mechanism. In addition, along with this, it is possible to eliminate the trouble of adjusting the vertical feed amount of a single time by the vertical feed mechanism according to the packing condition of the strawberries.

[0008] Further, a detecting means for detecting the presence or absence of the seedling pot passing along with the vertical feeding of the mat-like seedlings by the vertical feeding mechanism, and the mat-like seedlings of the mat-like seedlings by the vertical feeding mechanism based on the detection information from the detecting means. Since there is a detection means for detecting the vertical feed state, if an abnormality occurs in the vertical feed of the mat-shaped seedlings (straw seedlings) by the vertical feed mechanism, the detection means detects the mat-shaped seedlings by the vertical feed mechanism. It becomes possible to easily detect a vertical feed error.

[0009] Moreover, the straw-type seedlings vertically fed by the lengthwise-feeding mechanism are inserted into a plurality of seedling pots that are vertically and horizontally aligned with a predetermined interval, and the mat-shaped seedlings are inserted into each seedling pot. Since the seedlings are not seedlings, the strawberries are not in close contact with each other as in the case where the strawberries are divided into individual plants and packed in a state of being aligned vertically. Without needing a mechanism to clarify the boundaries between seedlings, for example, the presence or absence of seedling pots composed of non-contact or contact sensors or switches such as optical sensors, proximity switches, or micro switches A simple one that can be detected can be used. Also, as a detecting means, the amount of change does not change because the seedling interval does not change depending on the packing condition of the strawberries seedlings as in the case where the strawberries seedlings divided into each stock are packed in a state of being aligned in a vertical position. A simple structure without consideration can be adopted.

The detection of the vertical feeding state of the mat-like seedlings by the detecting means is based on the change state of the presence or absence of the seedling pot detected at each vertical feeding timing of the mat-like seedlings by the vertical feeding mechanism. The means is, for example, presence / absence of seedling pots detected by the detection means at each single vertical feed timing of mat-like seedlings by the vertical feed mechanism Yes → No → Yes or No →
In the state where there is a change from yes to no, it is detected that the vertical feeding of the mat-like seedlings by the vertical feeding mechanism is normal. On the other hand, when the presence or absence of the seedling pot detected by the detection means changes at each vertical feed timing of the mat-shaped seedlings by the vertical feed mechanism, only if there is a change in either → → or → → Detects that the vertical feeding of mat-shaped seedlings by the mechanism is abnormal due to insufficient vertical feeding,
When the presence / absence of seedling pots detected by the detection means changes from Yes → No → Yes → No or No → Yes → No → Yes, the vertical feed mechanism vertically feeds mat-shaped seedlings. The abnormality due to excess is detected.

In the mat-like seedling in which a plurality of seedling pots are formed, the width of the groove that divides the seedling pots is narrower than the width of the pot. In detecting the vertical feed state of the, if the detection means is configured to detect the presence / absence of seedling pots at each vertical feed timing of the mat-like seedlings by the vertical feed mechanism, it is possible to detect it. The detection accuracy is higher than in the case where the means is configured to detect the presence / absence of the seedling pot as Yes → No → Yes. Even if the detection means is configured to detect the presence / absence of seedling pots as →→ absent → presence, detection can be done by making the detection means consider the time during which the detection means detects the presence of seedling pots. The accuracy can be increased.

Therefore, according to the invention described in claim 1, it is possible to suppress the inconvenience that the planting mechanism causes the missing or over-planting of the strawberries in planting, and the vertical feeding mechanism enables the vertical growth of the strawberries. A structure for detecting a feed error can be easily obtained without complicating it.

According to the second aspect of the present invention,
A longitudinal feeding mechanism for intermittently longitudinally feeding a mat-like seedling formed by inserting each one of the strawberries in a plurality of seedling pots formed in a state of being aligned at predetermined intervals in the vertical and horizontal directions, and the mat Detecting means for detecting the presence or absence of the stem portion of the strawberries seedlings that pass along with the vertical feeding of the seedlings, and detecting the vertical feeding state of the mat-like seedlings by the vertical feeding mechanism based on the detection information from the detecting means. And a detection means for doing so.

According to the second aspect of the present invention, the same action and effect as those of the above-mentioned first aspect of the invention can be obtained, and in addition, the stalk of the strawberries seedlings which is on the upper open side of the seedling placing table with respect to the seedling pot. Since the presence or absence of the part is detected by the detecting means, the detecting means can be arranged more easily than the case where the presence or absence of the seedling pot is detected by the detecting means.

According to the second aspect of the invention, the detecting means is configured to detect the presence or absence of the stem portion of the strawberries seedling,
Further, in the mat-like seedling, the width between the seedlings is wider than the width of the stem portion of the straw grass seedling, so that the detection means is provided at each vertical feed timing of the mat-like seedling by the vertical feed mechanism. If it is configured to detect the presence / absence of stalks of strawberries as compared with the case where the detection means is configured to detect the presence / absence of stalks of strawberries as compared with the case of →→→ Higher detection accuracy. By the way, the detection means does not detect the presence or absence of stalks of strawberries →
Even when configured to detect the presence → absence, the detection accuracy can be improved by allowing the detection means to consider the time during which the detection means detects the absence of the stalk of the strawberries seedling. Become. In addition, since the stalk of strawberries is relatively hard and has rigidity, even in this configuration,
A relatively inexpensive microswitch can be used as the detection means.

Therefore, according to the second aspect of the present invention, it is possible to suppress the inconvenience that the planting mechanism causes a missing strain or over-planting at the time of planting the strawberries seedlings, and the vertical feeding mechanism enables the vertical growth of the strawberries seedlings. It has become easier to obtain a configuration for detecting a feed error.

In the invention according to claim 3 of the present invention,
In addition to the invention described in claim 1 or 2, the detection means is configured to activate the alarm means when the vertical feed mechanism detects an abnormal vertical feed of the mat-shaped seedlings.

According to the third aspect of the present invention, when an abnormality occurs in the vertical feeding of the mat-shaped seedlings by the vertical feeding mechanism, the detecting means activates the alarm means (for example, a lamp or a buzzer). From this, the worker can easily recognize the vertical feeding abnormality of the mat-like seedling by the vertical feeding mechanism, and thereby without having to frequently and carefully visually check the state of the field after the planting work while performing the planting work, It becomes possible to easily recognize a situation where there is a stockout or overstocking due to an abnormal vertical feed of the mat-shaped seedlings by the vertical feed mechanism, or a situation in which there is a risk of such occurrence. In addition, by stopping the planting work in response to this recognition, it is possible to prevent the planting work from continuing in the state of missing stocks and overstocks, and to perform good maintenance again by performing appropriate maintenance. You will be able to work.

Therefore, according to the third aspect of the present invention, it is possible to eliminate inconveniences such as stockouts and overstocks early or in advance while reducing the labor of workers.

In the invention according to claim 4 of the present invention,
In addition to the invention according to claim 1, 2 or 3, the detecting means detects the vertical feeding abnormality of the mat-like seedlings by the vertical feeding mechanism, and the vertical feeding mechanism vertically detects the mat-like seedlings. It is configured to automatically adjust the feed amount.

According to the invention of claim 4, the detecting means automatically adjusts the vertical feed amount of the mat-like seedlings by the vertical feed mechanism when the vertical feed mechanism detects an abnormal vertical feed of the mat-like seedlings. If the vertical feeding mechanism causes an abnormal vertical feeding of mat-shaped seedlings, the vertical feeding mechanism can adjust the vertical feeding amount of the mat-shaped seedlings to a suitable vertical length without the operator having to temporarily stop the planting work for maintenance. The feed amount can be automatically adjusted. As a result, it becomes possible to automatically avoid the stock-out or overstocking caused by the vertical-feeding abnormality of the mat-shaped seedling by the vertical feed mechanism or the occurrence of stockout or overstocking.

Therefore, according to the invention described in claim 4, the inconvenience such as stock-out or over-stocking can be eliminated early or in advance while further reducing the labor.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows the entire side surface of the strawberry planting machine. This strawberry planting machine is provided with a seedling planting device 3 through a lifting link mechanism 2 at the rear part of a traveling machine body 1 constructed as a riding type. It is configured by connecting the up and down freely.

As shown in FIG. 2, the seedling planting device 3 includes a feed case 4 to which power from the traveling machine body 1 is transmitted.

It is composed of a seedling placing table 7 which reciprocates laterally with a constant stroke, and a leveling float 8 which applies a leveling action to the seedling planting site by the planting mechanism 6. The mat-shaped seedlings 9 corresponding to the number of planting rows are placed on the seedling placement table 7 in parallel. As shown in FIG. 3, the mat-shaped seedlings 9 are prepared by inserting the strawberries seedlings 9c one by one into a plurality of seedling pots 9b defined by the V-shaped grooves 9a in a state of being aligned at a predetermined interval in the vertical and horizontal directions. Has been formed. That is, the seedling planting device 3 seeds the strawberries seedlings 9c one by one from each mat-like seedling 9 placed on the seedling placing table 7 in which each planting mechanism 6 reciprocates laterally by the power from the traveling body 1 side. The pot 9b is cut out and planted in the field.

As shown in FIGS. 1 and 2, the seedling placing table 7
The mat-like seedlings 9c are cut at a predetermined pitch (seedling pots 9b) every time the strawberries and seedlings 9c corresponding to the lower end horizontal row are cut off by the planting mechanism 6 from the mat-like seedlings 9 placed on the seedling placing table 7 which moves back and forth. The vertical feed mechanism 10 is installed in parallel for the number of planting threads that intermittently feeds vertically at a pitch of 1). Each longitudinal feed mechanism 10 is composed of a pair of upper and lower rolling wheels 10A and 10B and an endless belt 10C with a projection wound around the pair of upper and lower rolling wheels 10A and 10B, and reciprocally moves laterally on the seedling table. Each time 7 reaches each of the left and right stroke ends, the power from the feed case 4 is linked so as to be passed from the feed case 4 to the vertical feed mechanism 10, and the transmission link mechanism 11 and the lower side rolling mechanism. The mat-shaped seedlings 9 are transmitted at a predetermined pitch (for one pitch of the seedling pot 9b) by being transmitted through the one-way clutch 13 interposed between the wheel 10B and the drive shaft 12.
Only the lower side (planting mechanism 6 side) is vertically fed.

As shown in FIGS. 2 and 4 to 6, a plurality of vertical wall portions 7A are formed in parallel on the seedling placing table 7 to divide the placement surface on which the mat-like seedlings 9 are placed into the number of planting rows. Each vertical wall portion 7A (vertical wall portion 7A corresponding to the number of planting rows) except one vertical wall portion 7A passes through the vertical feeding mechanism 10 as the mat-shaped seedling 9 is vertically fed. The microswitch serving as the detection means 14 for detecting the presence / absence of the presence or absence of 9b has the detection piece 14a whose mating seedling 9 is the seedling pot 9
When the seedling pot 9b located at the lowermost end of the mat-shaped seedling 9 is accurately positioned at the seedling take-out position of the seedling placing table 7, the detection piece 14a is a mat-shaped seedling. It is equipped so as to be engaged with the V-shaped groove 9a of 9 to detect the OFF state. Each micro switch 14
Is configured to output the detection information (on / off signal) to the control device 15 as the presence / absence of the seedling pot 9b is detected. The control device 15 is provided with a detection means 15A as a control program for detecting the vertical feed state of the mat-shaped seedling 9 by the vertical feed mechanism 10 based on the ON / OFF signal from each microswitch 14.

More specifically, the detection of the vertical feeding state of the mat-shaped seedling 9 by the detection means 15A is detected by each microswitch 14 at each vertical feeding timing of the mat-shaped seedling 9 by each vertical feeding mechanism 10. This is based on the change state of the presence or absence of the seedling pot 9b (on / off signal from each microswitch 14), and the detection means 15A is provided at each vertical feed timing of the mat-shaped seedling 9 by each vertical feed mechanism 10. Seedling pot 9 detected by each microswitch 14
In the state where the presence or absence of b changes, for example, as shown in (a) of FIG. 7, no → present → none (the on / off signal from each microswitch 14 is off → on → off), each vertical It is configured to detect that the vertical feeding of the mat-shaped seedling 9 by the feeding mechanism 10 is normal. On the other hand, each vertical feed mechanism 10
The presence / absence of the seedling pot 9b detected by any of the microswitches 14 at each vertical feed timing of the mat-like seedling 9 is determined as shown in (b) of FIG.
In a state where only the change (ON / OFF signal from any one of the microswitches 14 is changed from OFF to ON), the mat-like seedling 9 by the vertical feeding mechanism 10 of the planting row to which the detected microswitch 14 belongs is detected. It is detected that the vertical feed of the seedling is abnormal due to insufficient vertical feed, and the seedling pot 9b detected by any of the microswitches 14 is detected.
The presence / absence of, for example, as shown in (c) of FIG.
No → Yes (ON from any micro switch 14
In the state in which the OFF signal changes from OFF to ON to OFF to ON), the vertical feed of the mat-like seedling 9 by the vertical feed mechanism 10 of the planting strip to which the microswitch 14 that has performed the detection is abnormal due to excessive vertical feed. Is detected.

Further, the detecting means 15A detects an abnormal vertical feeding of the mat-shaped seedling 9 by any one of the vertical feeding mechanisms 10 based on the ON / OFF signal from each microswitch 14, and the abnormality detection is performed. When it is repeated a predetermined number of times (for example, twice), an abnormal vertical feed is detected among the lamps 16 corresponding to the number of planting threads corresponding to each vertical feed mechanism 10 provided as the alarm means 16 in accordance with the detection. The lamp 16 corresponding to the vertical feed mechanism 10 is operated to blink.

With the above configuration, when an abnormality occurs in the vertical feeding of the mat-shaped seedling 9 by any of the vertical feeding mechanisms 10, the detecting means 15A causes the vertical feeding mechanism 1 to have an abnormal vertical feeding.
Since the lamp 16 corresponding to 0 is operated to blink, the worker can easily recognize the vertical feeding abnormality of the mat-shaped seedling 9 by the vertical feeding mechanism 10, and the planting work can be performed in accordance with this recognition. By temporarily stopping the planting operation, the planting work is continued in a state where the vertical feed mechanism 10 causes the vertical feeding abnormality of the mat-shaped seedlings 9 to cause a stockout or overstocking, or a stockout or overstocking occurs. It can be prevented from occurring, and proper planting work can be performed again by performing appropriate maintenance (adjustment of the vertical feed mechanism 10 and the transmission link mechanism 11). In other words, while performing the planting work, there is no need for frequent and careful visual inspection to see if there are any missing or over-planted fields in the field after planting work. You can do it.

The reference numeral 17 in the figure indicates a straw seedling 9c.
Is a guide rod that guides the stem portion of the strawberries seedling 9c to the inner side of the mat-shaped seedling 9 so that the stem portion of the seedling 9c does not accidentally contact the detection piece 14a of the microswitch 14.

[Other Embodiments] Other embodiments of the present invention will be listed below. The microswitch 14 as the detection means 14 may be equipped so that the detection piece 14a abuts the seedling pot 9b of the mat-shaped seedling 9 from the lateral side. When the seedling pot 9b located at the lowermost end of the mat-like seedling 9 is accurately positioned at the seedling taking-out position of the seedling placing table 7, the detection piece 14a of the microswitch 14 as the detecting means 14 is You may equip with the seedling pot 9b, and equip it so that ON detection may be carried out. Since the stem portion of the strawberries seedling 9c is relatively hard and has rigidity, the microswitch 14 as the detection means 14 passes along with the vertical feeding of the mat-like seedlings 9 by the vertical feeding mechanism 10. The presence or absence of the stem portion of the mat-shaped seedling 9 is detected by the detection means 15A based on the detection information from the microswitch 14 (presence or absence of the stem portion of the strawberries seedling 9c). It may be configured to detect. As the detection means 14, for example, in addition to the contact-type micro switch 14, a proximity switch, an optical sensor, or
A non-contact type switch or sensor such as an ultrasonic sensor may be adopted. The detection unit 15A operates the lamp 16 as the alarm unit 16 corresponding to the vertical feed mechanism 10 in which the abnormality is detected depending on whether the detected vertical feed abnormality is insufficient vertical feed or excessive vertical feed. It may be configured to differ in method. For example, in the case of either one of vertical feed shortage and excessive vertical feed, the lamp 16 is turned on, and in the other case the lamp 16 is blinked, or the blinking interval is changed depending on insufficient vertical feed and excessive vertical feed. There is a method such as. The alarm means 16 may be provided with one lamp 16 or a buzzer, or the lamp 16 and a buzzer may be provided together. As shown in FIG. 8, each vertical feed mechanism 10 is composed of a pair of upper and lower rolling wheels 10A, 10B, an endless belt 10C with protrusions, and an electric motor 10D for driving the lower rolling wheel 10B, and a detecting means 15A. However, any one of the vertical feed mechanisms 1 based on the detection information from each detection means 14
When the vertical feed abnormality of the mat-shaped seedling 9 due to 0 is detected, the operation of the electric motor 10D of the vertical feed mechanism 10 in which the vertical feed abnormality is detected is controlled according to the detection, and the vertical feed mechanism 10 causes the vertical feed mechanism 10 to operate. The vertical feed amount of the mat-like seedling 9 may be automatically adjusted to an appropriate vertical feed amount. When the detection unit 15A detects an abnormal vertical feed of the mat-shaped seedling 9 by any of the vertical feed mechanisms 10 based on the detection information from each detection unit 14, the planting clutch is disengaged with the detection. The seedling planting device 3 is operated to stop the seedling planting operation, or the main clutch is disengaged to stop both the traveling of the traveling machine body 1 and the seedling planting device 3 of the seedling planting operation. Good.
