Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a labor performance method and a labor performance vehicle in an agricultural and livestock farm for cultivating agricultural products and raising livestock on a vast site. More specifically, the present invention is mounted detachably on the vehicle. This is related to measures to improve the spraying efficiency of compost and other additives necessary for the cultivation of agricultural products and the shipping efficiency of agricultural products by effectively using multiple types of containers.

[0002]

2. Description of the Related Art In Hokkaido and the like, agricultural and livestock industries, such as dairy farmers, are operated utilizing vast land. This agricultural and livestock industry puts excrement of livestock such as cows on a dump truck and transports it to a stockyard, and then puts and stores the excrement in the pit of this stockyard.
Excrete is composted after a certain period of time in the pit, and then the compost in the pit is loaded on the loading platform of the tractor by using the transshipment device, and the tractor is operated to the farm of the crops and placed on the loading platform of the tractor. Compost is sprayed in a farm by using a spraying device provided. Further, when water is sprayed on a farm, a watering vehicle equipped with a water tank is operated to the farm, and water is sprinkled on the farm by this watering vehicle.

On the other hand, the agricultural products harvested in the farm during the harvesting time of the agricultural products are placed on a loading platform such as a truck and transported from the farm to the cold storage, and the cold storage is ordered according to the order of shipment to a plurality of shipping sites. Store in a designated shelf. Then, at the time of shipment, a transport vehicle that operates between the farm and the shipping site is dispatched to the cool box, and the crops suitable for the shipping site are sequentially carried out from the cool box by a forklift or the like.
Agricultural products are loaded and shipped in the packing boxes of transport vehicles.

[0004]

However, in the above-mentioned ones, there is a constraint such that the agricultural products are fixed and stored in a predetermined shelf of a cool box in each order of shipment to a plurality of shipping sites at the time of harvesting the agricultural products. As a result, the storage work of the agricultural products becomes troublesome, and it is necessary to perform transshipping operations of the agricultural products twice for both the cool box and the carton of the carrier, which significantly deteriorates the shipping efficiency of the agricultural products. become.

In addition, when an additive such as compost is sprayed, it is necessary to separately prepare a loading device for loading the additive on the bed of the vehicle for compost spraying in the stockyard. In addition, in the case of spraying vehicles such as tractors, the traveling speed is very slow, and only a small amount of additive such as compost can be mounted on the loading platform, so that it is necessary to spread the additive on a vast farm. The spraying efficiency will be extremely poor. Moreover, in the above-mentioned agricultural and livestock farms, in addition to a transporting vehicle for shipping and a compost spraying vehicle, there is also a spraying vehicle dedicated to additives such as water.
Despite the tax, insurance, maintenance costs, etc. for each of these vehicles, leave the unnecessary vehicles aside during the harvest season of agricultural products and the time of spraying additional compost and water. Therefore, it is very disadvantageous in terms of vehicle maintenance cost.

The present invention has been made in view of the above points, and an object of the present invention is to effectively use a plurality of types of containers that can be loaded and unloaded on and from a chassis of a single vehicle, and to use the shipping place among them. Aim to improve the shipping efficiency of agricultural products by loading the agricultural products directly into the multiple 1st type containers of each It is intended to improve and to reduce the maintenance cost of the vehicle.

[0007]

[Means for Solving the Problems] In order to achieve the above-mentioned object, the means for solving the problems according to the invention of claim 1 is to store agricultural crops harvested at a farm on the premises of an agricultural and livestock farm and ship them if necessary. On the other hand, the excrement of livestock bred in the livestock house on the premises is stored as fertilizer, and the fertilizer is sprayed on the farm as needed. The harvested product is loaded into an empty container having means, and the harvested product is stored together with the container. At the time of shipping, the container loaded with the harvested product is mounted on a labor vehicle at a storage location and carried out to a shipping destination. On the other hand, livestock excrement is loaded into an empty container having a spraying means, the excrement is stored together with the container into compost, and at the time of fertilization, the container loaded with the fertilizer is mounted on a labor performance vehicle at a storage location. I try to carry it out to the farm and spray it.

[0008] The solving means taken by the invention of claim 2 is
As a labor performance vehicle, a first container having a cold storage means for loading harvested products at a farm on the premises of the farm and livestock, and a cold storage means for keeping the harvested products, and livestock bred in a livestock house on the premises are provided. A second container having a spraying means for loading excrement and spraying a compost composed of the excrement, and both of the above containers are detachably mounted, and the two containers are selected at the time of harvesting and at the time of fertilizing, and stored. It is configured to include a vehicle body that is transported among a location, a farm, and a shipping destination.

Thus, according to the first and second aspects of the present invention, by preparing a plurality of first containers, it becomes possible to use each first container as a storage according to each shipping place, and to keep the agricultural products cool. When storing in a warehouse, there is no restriction on the storage order such as storing the agricultural products in a predetermined shelf etc. according to the shipping order to multiple shipping destinations, and the agricultural products are sequentially stored in each first container for each shipping place. Loading and storage of agricultural products can be done smoothly.
Moreover, the agricultural products harvested at the farm are directly loaded into the first container, and the first container is loaded into the vehicle body before being shipped. Therefore, it is possible to store the agricultural products in the cold storage box and then load them into the cargo box of the carrier. 2 for transshipment of agricultural products
The farm products can be shipped smoothly without having to repeat the process once.

The excrement of livestock thrown into the second container is composted in the second container over time, and when necessary, the second container is loaded into a vehicle and taken out to the farm, where it is stored inside. Since the compost stored in the plant is sprayed, it is not necessary to separately prepare a loading device such as the case where the excrement of livestock is loaded into the stockyard and then loaded on the bed of the vehicle for spreading the compost. Further, since the compost is sprayed by the vehicle main body in which the second container is loaded, the traveling speed is increased as compared with a spraying vehicle such as a tractor system, and a large amount of compost is loaded using the second container. This makes it possible to dramatically improve the spraying efficiency of compost on a vast farm. Moreover, since the first and second containers are loaded and unloaded onto and from a single vehicle, there is no need to have a dedicated vehicle such as a transporting vehicle for shipping, a composting vehicle, or a watering vehicle. Costs such as insurance and maintenance will be kept down to one vehicle, and vehicle maintenance costs will be low.

The means for solving the problems according to the invention of claim 3 is as follows.
The cooling means of the invention according to claim 2 is specified. Specifically, the cold storage means is configured to be operated by the power source of the vehicle body with the first container loaded with the agricultural products mounted on the vehicle body.

Thus, according to the third aspect of the invention, the inside of the first container is kept cool even when the vehicle is traveling by using the power source of the vehicle body, and the agricultural products are shipped in a fresh state.

The means for solving the problems according to the invention of claim 4 is as follows.
The spraying means of the invention according to claim 2 is specified. Specifically, the rear surface of the second container is opened, and a gate for opening and closing the opening is provided in the opening, and the opening is closed by the gate when the compost is not sprayed. Then, the spraying means is provided with a floor conveyor that conveys the compost in the second container toward the opening, and a beater that finely crushes the compost in the opening is provided, and the floor conveyor is used when the compost is sprayed. The compost conveyed to the opening by means of the beater is finely crushed and sprayed from the opening.

Accordingly, in the invention according to claim 4, the second container loaded at the storage place is carried out to the farm by the vehicle, and the compost is sprayed by the spraying means while the vehicle is running in the farm. That is, the compost in the second container is conveyed by the floor conveyor toward the opening when the vehicle is running, then finely crushed by the beater and efficiently dispersed on the farm.

The solution provided by the invention of claim 5 is as follows.
The spraying means of the invention according to any one of claims 2 to 4 is specified. Specifically, the spraying means is operated by the power source of the vehicle body. Further, the control means provided in the vehicle body controls the operation of the spraying means.

Accordingly, in the invention according to claim 5, when there are a plurality of second containers, it is not necessary to separately provide a power source (actuation source) and a control means for each of the spraying means,
The power source and the control means are provided only in a single vehicle, and the equipment cost is reduced.

The means for solving the problems according to the invention of claim 6 is as follows.
In addition to the constituent features of the invention according to claim 5, in the control means,
The configuration is such that a changing means for changing the conveyance speed of the floor conveyor to a slow speed according to the vehicle speed is provided.

Thus, in the invention according to the sixth aspect, the conveying speed of the compost by the floor conveyor is changed to the slow speed according to the vehicle speed, so that the spraying efficiency of the compost is enhanced. Also,
Problems such as clogging of compost on the beater side due to excessively high transport speed of compost can also be eliminated.

According to the invention as set forth in claim 7, the solution means is:
As a labor execution vehicle, a vehicle body on which a compost consisting of livestock excrement is loaded or a detachable detachable container that is transported toward the farm during fertilization, and a chassis or desorption container on which the above compost is loaded are provided. A spraying means for spraying the compost and a control means provided on the vehicle body for controlling the operation of the spraying means are provided. The spraying means is provided with a floor conveyor that conveys the compost toward an opening opening to the rear of the chassis or the desorption container in which the compost is loaded, and a beater that finely crushes the compost in the opening is provided to spread the compost. At this time, the compost conveyed toward the opening by the floor conveyor is finely crushed by the beater and sprayed from the opening. Then, the control means, when the rotation speed of the beater is reduced, a conveyance speed delay means for delaying the conveyance speed of the floor conveyor according to the reduction amount of the rotation speed, and when the beater is stopped, the beater is restarted. The conveyance direction reversing means for reversing the conveyance direction of the floor conveyor repeatedly until it is activated is provided.

Accordingly, in the invention according to claim 7, when the rotation speed of the beater decreases when the compost is sprayed by the spraying means, the transport speed delay means causes the transport speed of the floor conveyor to be reduced according to the decrease amount of the beater rotation speed. Is delayed and the conveyance amount of compost to the beater by the floor conveyor is suppressed, so that clogging on the beater side due to compost or foreign matter is prevented in advance, and clogging on the beater side becomes serious and the beater stops. The situation of doing is effectively avoided. On the other hand, when the beater stops, the conveying direction reversing means repeatedly reverses the conveying direction of the floor conveyor until the beater is reactivated, and the clumps of compost and foreign matter that are blocked on the beater side are conveyed by the reverse conveying of the floor conveyor. It is possible to remove the beater by returning it to the side, and the stoppage of the beater due to the clogging of compost or foreign matter can be smoothly restored and the compost can be continuously sprayed.

Further, the solution means taken by the invention of claim 8 is characterized in that the control by the control means of the invention of claim 7 is specified. Specifically, the conveying direction reversing means is provided with a measuring means for measuring the number of times the conveying direction of the floor conveyor is repeatedly reversed. Further, the control means is configured to stop the operation of the spraying means when the beater does not re-operate even if the number of reverse rotations in the conveying direction of the floor conveyor is continuously measured by the measuring means for the set number of times.

Accordingly, in the invention described in claim 8, if the cause of the beater stop is, for example, a mass of compost or a foreign substance clogged on the beater side is not removed by the reverse conveyance of the floor conveyor, it is repeated more than that. It prevents you from wasting your time, and protects your beater from overdoing it.

-How to Use First Container- Next, an example of how to use the first container 2 at the farm and livestock farm 1 will be described.

The first container 2 is mounted on the container mounting table 33 of the vehicle main body Vx and is used by the farm and livestock farm 1
It is considered as the harvest time of the agricultural products cultivated in the farm 1a.

That is, the agricultural products harvested at the farm 1a are
The produce is transported to a farm storage place 1b by a truck or the like (not shown), and the farm produce is packed in a unit of weight or quantity in the store 1b. Next, the boxed agricultural products
The rear wall 2e of the first container 2 is opened and loaded into the accommodation portion. Then, the cold storage device 11 is driven by using the power source of the agricultural produce storage location 1b as a drive source to cool the accommodation portion of the first container 2 in the agricultural produce storage location 1b. In this case, each first
When the container 2 is used as a storage according to each shipping destination and the agricultural products are stored in the cool box, the storage order is restricted such that the agricultural products are stored in a predetermined shelf in each shipping order to a plurality of shipping destinations. Without receiving the agricultural products, the agricultural products can be sequentially loaded into the respective first containers 2 for each shipping place, and the agricultural products can be loaded (stored) smoothly.

After that, when the storage portion of the first container 2 is filled with the agricultural products, the vehicle body Vx is stored in the agricultural product storage location 1b.
To dispatch. In this farm produce storage location 1b, the driver's seat operation switch 64a is turned on, and the changeover switch 65a switches the interlocking switch 67a to the first changeover circuit 68 side to close the cargo handling device drive circuit 71.

After the sliding solenoid switching valve 48 is switched to the position where the pressure oil is supplied to the rod chamber of the sliding cylinder 37 to contract the sliding cylinder 37, the lift cylinder 3
6, the lift electromagnetic switching valve 47 is switched to a position where pressure oil is supplied to the head chamber, and the lift cylinder 36 is extended to erect the cargo handling frame 34. Next, the hook 34c at the tip of the L-shaped frame portion 34b is engaged with the hook engaging portion 6 of the first container 2. After that, the lift electromagnetic switching valve 47 is switched to a position where pressure oil is supplied to the rod chamber of the lift cylinder 36 and the lift cylinder 36 is contracted, so that the cargo handling frame 34 is laid down to the rear of the container mounting table 33. Place the first container 2. After that, the electromagnetic switching valve 48 for sliding is switched to a position where pressure oil is supplied to the head chamber of the sliding cylinder 37 to extend the sliding cylinder 37, so that the first container 2 reaches the regular position of the container mounting table 33. Slide the container mounting table 3
The mounting of the first container 2 on 3 (the underframe 32) is completed. As a result, the crops harvested at the farm 1a are packed in boxes and directly loaded into the accommodation portion of the first container 2,
The first container 2 is placed on the container mounting table 33 of the vehicle body Vx.
Since the cargo is loaded by the cargo handling device 30 and shipped, it is not necessary to perform the transshipment work of the crop twice, unlike the case where the crop is stored in the cool box and then loaded in the packing box of the carrier, so that the crop can be shipped efficiently. It can be carried out.

Next, after the coupler of the cooler 11 is replaced with the outlet of the battery B of the vehicle body Vx, the operation switch 64a in the driver's seat is turned off, and then the vehicle body Vx is carried out to the shipping place. As a result, the inside of the first container 2 is kept cool even while traveling by using the battery B of the vehicle body Vx, and the agricultural products can be shipped in a fresh state.

Thereafter, the vehicle body V returned from the shipping place.
The first container 2 is lowered from the container mounting table 33 of x by the cargo handling device 30 to the crop storage place 1b. This descending operation is performed after the vehicle body Vx is dispatched as described above after the L-shaped frame portion 34.
The operation procedure is the same as the case of performing the loading operation of the cargo handling device 30 until the hook 34c at the tip of b is engaged with the hook engaging portion 6 of the first container 2, and the description thereof is omitted.

-Usage Method of Second Container- Next, an example of the usage method of the second container 3 in the agricultural and livestock farm 1 will be described.

The second container 3 is mounted on the vehicle and used when it is necessary to spray the compost on the farm 1a (during fertilization).

First, the excrement of cows carried by a truck (not shown) from the barn 1c is put into the accommodating portion of each second container 3 arranged in the storage place 1d, and the excrement accumulated in the accommodating portion of the second container 3 is discharged. Compost is made by letting things age for a certain period of time and aging. In this way, after a predetermined period of time,
When applying the compost in the second container 3 to the farm 1a,
The vehicle body Vx is dispatched to the storage location 1d. Since the mounting of the second container 3 on the container mounting table 33 at the storage location 1d is the same as the mounting procedure of the first container 2 described above, the description thereof will be omitted.

Then, the container mounting table 3 of the vehicle body Vx
After the mounting of the second container 3 on the upper part 3 is completed, the gate cylinder 23, the conveyor motor 25d and the beater motor 27 are installed.
, The hydraulic couplers 42a, 42a for hydraulic supply / discharge of the hydraulic supply / discharge device 41 of the vehicle body Vx are respectively coupled, and then the second container 3 is transported to the farm 1a by the vehicle body Vx.

After that, in the farm 1a, after turning on the operation switch 64a on the driver's seat, the changeover switch 65a is turned on.
To switch the interlocking switch 67a to the second switching circuit 69 side and to switch the gate cylinder opening / closing switch 72a to the first switching circuit 74 side.
The gate electromagnetic switching valve 50 is switched to a position where pressure oil is supplied to the head chamber 3 to open the gate 21.

Then, the beater motor forward / reverse rotation switch 73a on the driver's seat is switched to the first switching circuit 76 side,
The beater motor electromagnetic switching valve 51 is switched to the forward rotation position so that the beater 2 above and below when viewed from the left side of the second container 3
6 and 26 are each rotated clockwise. After that, while running the vehicle body Vx vertically and horizontally on the farm 1a,
The conveyor drive switch 65b in the driver's seat is turned on to switch the conveyor electromagnetic switching valve 49 to the forward rotation position, and the voltage changing unit 66 is operated in accordance with the turning amount of the driver's seat.
Change the voltage at a to the desired value. As a result, the floor conveyor 25 is driven so as to convey the compost toward the rear opening end side at a desired conveying speed, the compost conveyed backward by the floor conveyor 25 is finely crushed by the beater 26, and the compost is separated between the beaters 26. Also, a large amount of compost can be efficiently and reliably sprayed from above the upper beater 26 (spraying state shown in FIG. 7). At this time, by changing the voltage of the voltage changing unit 66a according to the vehicle speed to convey the compost at a desired conveying speed,
The spraying efficiency of the compost in the second container 3 can be improved. Further, it is possible to solve the problem that the compost is clogged on the beater 26 side due to the fact that the compost is conveyed too fast by the floor conveyor 25.

Thereafter, when the compost in the second container 3 is exhausted, the conveyor drive switch 65b in the driver's seat is turned off to switch the conveyor electromagnetic switching valve 49 to the neutral position (the position shown in FIG. 6). The floor conveyor 25 is stopped. On the other hand, the beater motor forward / reverse rotation switch 73a on the driver's seat is switched to the neutral position (the position shown in FIG. 6) to return the beater motor electromagnetic switching valve 51 to the neutral position, and the upper and lower beaters 26 are stopped. Next, the gate cylinder opening / closing switch 72a in the driver's seat is switched to the second switching circuit 75 side, and the gate solenoid switching valve 50 is switched to a position for supplying pressure oil to the rod chamber of the gate cylinder 23 by exciting the solenoid SOL4. After closing the gate 21, the operation switch 64a is turned off. After that, the vehicle body Vx
To the storage location 1d, and the cargo handling device 30 lowers the empty second container 3 from the container mounting table 33. At this time, when it is still necessary to spray the compost in the farm 1a, another table 2 container 3 storing the compost is mounted on the container mounting table 33 of the vehicle body Vx by the cargo handling device 30,

As a result, the second container 3 is loaded on the container mounting table 33 of the vehicle body Vx by the cargo handling device 30, and the compost in the second container 3 is sprayed on the farm 1a by the compost spraying device 24. Costs can be reduced because it is not necessary to prepare a separate loading device like the one that loads livestock excrement into the stockyard and then loads it on the bed of the composting vehicle. Further, since the vehicle body Vx loaded with the second container 3 disperses the compost, the traveling speed on the farm 1a is increased as compared to the case of the tractor type spreading vehicle, and the second container 3 is used. As a result, a large amount of compost can be loaded, and the spraying efficiency of compost on the vast farm 1a can be dramatically improved. Moreover, the first and second containers 2 and 3 are loaded and unloaded by the cargo handling device 30 onto and from the container mounting table 33 of the single vehicle body Vx, so that a shipping vehicle, a composting vehicle, a watering vehicle, etc. It is not necessary to own a dedicated vehicle, and costs such as taxes, insurance, and maintenance costs of the vehicle body Vx can be suppressed to one, and the maintenance cost of the vehicle body Vx can be reduced.

The composting device 24 of the second container 3
(Floor conveyor 25 and beater motor 27), a hydraulic pressure supply / discharge device 41 (each electromagnetic switching valve 46 to 51) as a drive source for the gate 21, and a control circuit 61 for switching each electromagnetic switching valve 46 to 51 are provided in the vehicle body Vx. Therefore, it is not necessary to individually provide the hydraulic pressure supply / discharge device 41 and the control circuit 61 for each of the plurality of second containers 3, and the facility cost can be reduced.

-Utilization Method of Third and Fourth Containers- Next, an example of the utilization method of the third and fourth containers 4 and 5 in the agricultural and livestock farm 1 will be described.

The third container 4 is mounted on the vehicle and used when it is necessary to spray water on the farm 1a.
On the other hand, it is the farm 1 that uses the fourth container 5 onboard.
It is said that it is necessary to spray a diluted chemical solution (for example, an insect repellent) on a.

First, when the water in the third container 4 arranged in the water supply place 1e is sprayed on the farm 1a, the water supply place 1e
The vehicle body Vx is dispatched to. Third at this water supply location 1e
Since the mounting of the container 4 on the container mounting table 33 is the same as the mounting procedure of the first container 2 described above, the description thereof will be omitted.

Then, the container mounting table 3 of the vehicle body Vx
After the completion of mounting the third container 4 on the vehicle 3, the hydraulic pressure supply / discharge device 4 of the vehicle body Vx is supplied to the pump of the sprinkler (not shown).
The first hydraulic couplers 42a and 42a are connected to each other, and then the vehicle body Vx is operated to the farm 1a.

Then, while the vehicle main body Vx is running vertically and horizontally in the farm 1a, the pump is driven and water is sprinkled by the sprinkler.

Thereafter, when the water in the third container 4 is exhausted, the sprinkler is stopped, the vehicle body Vx is operated to the water supply place 1e, and the cargo handling device 30 causes the empty container mounting table 33 to move to an empty first position. 3 Drop container 4 At this time, when it is still necessary to sprinkle water on the farm 1a, water is replenished in the third tank 4 at the water supply place 1e, and the water is returned to the farm 1a to repeat watering.

On the other hand, when the diluted chemical liquid in the fourth container 5 arranged at the water supply place 1e is sprayed on the farm 1a, the vehicle body Vx is allocated to the water supply place 1e. Mounting the fourth container 5 on the container mounting table 33 at the water supply place 1e also
The procedure is the same as the procedure for mounting the first container 2 described above.

Then, the container mounting table 3 of the vehicle body Vx

Then, while the vehicle body Vx is running vertically and horizontally on the farm 1a, the pump is driven to spray the diluted chemical liquid with the water spray device.

Thereafter, when the diluted chemical liquid in the fourth container 5 is exhausted, the water sprinkling device is stopped, the vehicle body Vx is operated to the water supply place 1e, and the cargo handling device 30 makes the empty space on the container mounting table 33. Lower the fourth container 5. At this time, when it is still necessary to spray the diluted chemical liquid in the farm 1a, the chemical liquid and water are replenished in the fourth tank 4 at the water supply place 1e, and the water is returned to the farm 1a to repeat the sprinkling.

Next, a second embodiment of the present invention will be described with reference to FIGS.

In the second embodiment, the structure of the conveyor motor control circuit is partially changed.

That is, as shown in FIG. 8, the output signal from the rotary encoder 81 for detecting the rotation speed of the beater motor 27 is input to the voltage conversion section 66a of the conveyor motor control circuit 66. Specifically, the voltage signal obtained by converting the pulse signal from the rotary encoder 81 by the pulse converter 82 and further amplifying it by the amplifier 83 is input to the voltage conversion unit 66a.

The beater motor 27 is provided with a pressure pressure switch (not shown), which is turned on when the load of the beater motor 27 becomes large.
N operation is performed to detect a large load of the beater motor 27. Then, the conveyor motor control circuit 66

The conveyor motor forward rotation drive circuit 65c is connected to a solenoid SOL1 for switching the conveyor electromagnetic switching valve 49 to the conveyor motor forward rotation drive position during excitation. On the other hand, the conveyor motor reverse rotation drive circuit 65d is connected to a solenoid SOL7 that switches the conveyor electromagnetic switching valve 49 to the conveyor motor reverse rotation drive position during excitation. The conveyor drive switch 65b can be switched by the conveyance direction reversing means 85 described later.

The voltage converter 66a includes a floor conveyor 2 provided in a second container 3 as a detachable container.
5. Conveyance speed delay means 84 for decreasing the number of rotations of the conveyor motor 25 to delay the conveyance speed of No. 5, and conveyance direction reversing means 85 for reversely rotating the conveyor motor 25d so as to repeatedly reverse the conveyance direction of the floor conveyor 25. ing. The carrier speed delay means 84 receives the voltage signal from the rotary encoder 81 that has passed through the pulse converter 82 and the amplifier 83, and responds to the voltage signal from the rotary encoder 81 when the rotation speed of the beater motor 27 decreases. The number of rotations of the conveyor motor 25 is reduced. Further, the conveying direction reversing means 85
Similarly inputs the voltage signal from the rotary encoder 81, and when the beater motor 27 is stopped, the conveyor drive switch 6 is operated until the beater motor 27 is restarted.
5b is switched to rotate the conveyor motor 25d in the reverse direction.

The carrying direction reversing means 85 is provided with a counter 86 as a measuring means for counting the number i of times the conveyor motor 25d is repeatedly rotated in the reverse direction. The carrying direction reversing means 85 repeats the carrying direction of the floor conveyor 25. The number of times i of reverse rotation is counted by the counter 86. In this counter 86, the number of reverse rotations i of the floor conveyor 25 is continuously increased to the maximum value n (n>n>
If the beater motor 27 does not reactivate even after counting i) times and counting the number of reverse rotations i up to the maximum value n times, the operation switch 65a (shown in FIG. 10) is forcibly switched to the non-energized state. The operation of the conveyor motor 25d and the beater motor 27 is stopped, and the control of the compost spreading device 24 thereafter is stopped.

The contact 66b of the voltage changing unit 66a is
By the transfer speed delay means 84, the transfer speed delay means 84
It is adapted to be changed according to the voltage signal input to. The voltage conversion unit 6 of the conveyor motor control circuit 66
The rest of the configuration except 6a is the same as that of the above-described embodiment, and the same portions are denoted by the same reference numerals and detailed description thereof is omitted.

Here, the control of the compost spraying apparatus 24 by the conveyor motor control circuit 66 in the farm 1a will be described based on the flowchart shown in FIG.

In this case, in controlling the composting device 24, after the operation switch 64a on the driver's seat is turned on, the interlocking switch 67a is switched to the second switching circuit 69 side by the changeover switch 65a and the gate cylinder opening / closing switch 72a is turned on. The gate 2 by switching to the first switching circuit 74 side
1 shall be left open.

First, the beater motor forward / reverse rotation switch 73a in the driver's seat is switched to the side of the first switching circuit 76, that is, the beater motor electromagnetic switching valve 51 is switched to the forward rotation position, and the upper and lower beaters 26, 26 are moved to the second container 3. While turning clockwise when viewed from the left side, the conveyor drive switch 65b in the driver's seat is turned on to start the operation of the compost spreading device 24, and the vehicle main body Vx travels vertically and horizontally in the farm 1a.

Then, in step S1 shown in FIG. 9, the rotary encoder 81 detects the number of revolutions of the beater motor 27. Next, in step S2, it is determined whether the load of the beater motor 27 is large or not by the ON / OFF determination of the pressure pressure switch.

When the determination in step S2 is NO, that is, when the pressure pressure switch is OFF and the load on the beater motor 27 is small, normal operation is performed in step S3.

On the other hand, it is determined in step S2 that the pressure motor switch is ON and the beater motor 27
Is large, the pulse signal of the rotary encoder 81 detected in step S1 is converted into a voltage signal by the pulse converter 82 in step S4, and the voltage signal is amplified by the amplifier 83 in step S5. At this time, the conveyor motor control circuit 66 is closed.

Then, in step S6, the contact 6 of the voltage changing portion 66a is responsive to the voltage signal in step S5.
6b is changed, the flow rate of the electromagnetic switching valve 49 for the conveyor is controlled, and in step S7, the rotation speed of the conveyor motor 25d is decreased to delay the conveyance speed of the floor conveyor 25,
Return to step S1. As a result, it is possible to prevent clogging on the beater 26 side due to compost or foreign matter, and it is possible to effectively avoid a situation where the clogging on the beater 26 side becomes serious and the beater motor 27 stops.

If it is determined in step S2 that the pressure pressure switch is ON and the beater motor 27 is stopped, the process proceeds to step S8, in which the first timer starts measuring the time after the beater motor 27 is stopped. In S9, after waiting until the measurement time of the first timer (for example, several seconds) elapses, in step S10, the beater motor 2
7. Determine if 7 has reactivated. This step S10
If it is determined that the beater motor 27 is reactivated, the process returns to step S1.

On the other hand, if the beater motor 27 does not restart, the beater electromagnetic switching valve 50 is switched to the neutral position and the beater motor 27 is temporarily stopped in step S11. Next, in step S12, the conveyor drive switch 65b is switched to convey the conveyor motor reverse rotation drive circuit 65.
After energizing the solenoid SOL7 of c, the conveyor electromagnetic switching valve 49 is switched to the conveyor motor reverse rotation driving position and the conveyor motor 25d is rotated in the reverse direction, and then step S13.
Then, the second timer starts measuring the time after the reverse rotation of the conveyor motor 25d is started.

After that, in step S14, after waiting until the measurement time of the second timer (for example, ten and several seconds) elapses,
In step S15, it is determined whether or not the beater motor 27 has restarted. If the beater motor 27 is restarted in the determination in step S15, in step S16, the conveyor drive switch 65b is switched to excite the solenoid SOL1 of the conveyor motor forward rotation drive circuit 65c, and the conveyor electromagnetic switching valve 49 is moved to the conveyor motor forward direction. After switching to the rolling drive position and rotating the conveyor motor 25d in the forward direction, the process returns to step S1. As a result, the beater motor 27
Even if is stopped, the conveyance direction of the conveyor belt 25d is repeatedly reversed in the reverse direction until the beater motor 27 is reactivated, so that the lumps of compost and foreign matter that are clogged on the beater 26 side are conveyed by the floor conveyor 25 in the reverse direction. It is possible to remove the beater 26 by returning it to the side, and the stop of the beater 26 due to clogging of compost or foreign matter can be smoothly restored, and the compost can be continuously sprayed.

If the beater motor 27 does not restart in the determination of step S15, step S1
7, the number of times the conveyor motor 25d was rotated in the reverse direction i
Is incremented by 1 by the counter 86, and in step S18,
It is determined whether the number i of reverse rotations of the floor conveyor 25 has reached the maximum value n, and if the number i of reverse rotations of the floor conveyor 25 has not reached the maximum value n, the above step S
12, the conveyor motor 25d is reversely rotated until the number i of reverse rotations of the floor conveyor 25 reaches the maximum value n.
When the number i of reverse rotations of the floor conveyor 25 reaches the maximum value n, the operation switch 65a is forcibly switched to the non-energized state to convey the conveyor motor 25d and the beater motor 27.
Is stopped, and the control of the composting device 24 thereafter is stopped. Thus, when the cause of the stop of the beater motor 27 is, for example, a mass of compost or a foreign substance clogged on the beater 26 side is not removed by the reverse conveyance of the floor conveyor 25, it is possible to prevent waste of time repeatedly. In addition, the beater 26 can be protected before it becomes important by not forcing the beater 26 too much.

In the second embodiment described above, the compost spraying device 24 is provided in the second container 3, but the undercarriage as the chassis of the vehicle body of the labor servicing vehicle is improved so that it can be loaded with compost. A floor conveyor may be provided on the underframe.
