Summary of the Invention

Problems to be Solved by the Invention

[0004] However, it does not prevent the invasion of slugs that lay eggs and reproduce in water channels into the field.

[0005] Therefore, the present invention has been made in view of the above, and an object thereof is to provide a slug control device that kills and controls slugs before they invade the field.

Means for Solving the Problems

[0006] The invention according to claim 1 is a slug control device characterized in that when traveling on a concrete ridge A, the left and right crushers 4, 4 contact and rotate on the left and right side surfaces of the concrete ridge A to peel off and drop the eggs of slugs laid on the side surface of the concrete ridge A from the ridge A.

[0007] According to the invention described in claim 1, since apple snail eggs cannot hatch in water, when the apple snail extermination device moves along the concrete levee A on the traveling devices 3,3, the left and right crushing tools 4,4 come into contact with the left and right sides of the concrete levee A and rotate, peeling off the apple snail eggs laid on the sides of the concrete levee A and immersing them in the water of the waterway or field, thus preventing them from hatching. Apple snails can be killed and exterminated before they hatch and invade the field.

[0008] The invention described in claim 2 is a snail extermination device according to claim 2, characterized in that it is equipped with an obstacle detection sensor (10) that monitors the direction of travel, stops moving when it detects an obstacle in the direction of travel, and moves in the reverse direction if the obstacle detection sensor (10) detects an obstacle in the direction of travel and stops moving, and the obstacle does not disappear even after a predetermined time has elapsed. [Brief explanation of the drawing]

[0009] [Figure 1] This is a perspective view of an apple snail extermination device according to an embodiment of the present invention. [Modes for carrying out the invention]

[0010] The following describes an apple snail extermination device, which is one embodiment of the present invention. While directions are conveniently indicated as front, back, left, and right based on the forward direction of the device, the configuration is not limited by these directions.

[0011] As shown in Figure 1, the apple snail extermination device 1 has front and rear running rollers 3, 3 that can be driven and rotated at the front and rear of the main body 2, and left and right crushing rollers 4, 4 that can be freely rotated and extend downward to the left and right.

[0012] The main body 2 houses a battery 5, front and rear electric motors 6, 6, and a control device 7. The top surface of the main body 2 is equipped with a power switch 8, a start switch 9, an ultrasonic sensor 10 as an obstacle detection sensor, a spacing change switch 11 to change the left-right spacing between the left and right crushing rollers 4, 4, and a vertical change switch 12 to change the vertical position of the left and right crushing rollers 4, 4.

[0013] The front and rear rollers 3,3 are mounted on left and right drive shafts that are driven and rotated by front and rear electric motors 6,6, each powered by battery 5. When the power switch 8 is turned on and the start switch 9 is pressed, the front and rear electric motors 6,6 are activated and the front and rear rollers 3,3 are driven and rotated.

[0014] The left and right crushing rollers 4,4 are hard rubber rollers that are freely rotatable on left and right pivot shafts that extend downward from the left and right sides of the main body 2. The left and right spacing between the left and right crushing rollers 4,4 can be changed by moving the base of the left and right pivot shafts in the left and right direction using a screw (screw shaft, or a rack and pinion mechanism or electric cylinder) that operates in the left and right direction by operating the spacing change switch 11, thereby accommodating various left and right widths of the concrete ridge A.

[0015] Furthermore, even when the left and right crushing rollers 4,4 are spaced at their maximum distance, the gap is such that the left and right crushing rollers 4,4 do not touch the seedlings planted in the field.

[0016] Furthermore, the left and right pivot shafts that pivotally support the left and right crushing rollers 4,4 so that they can rotate freely are extendable and retractable in the vertical direction by a screw (screw shaft, or a rack and pinion mechanism or electric cylinder) that is operated by the operation of the up and down change switch 12, so that the vertical height of the left and right crushing rollers 4,4 can be changed.

[0017] Therefore, the apple snail extermination device 1 is placed on the concrete ridge A of the field at the starting position, with the left and right crushing rollers 4,4 sandwiching the concrete ridge A of the field. The power switch 8 is turned on, and the up / down change switch 12 is operated to adjust the vertical height of the left and right crushing rollers 4,4 to the appropriate working height. The spacing change switch 11 is operated to adjust the spacing between the left and right crushing rollers 4,4 so that they contact the side wall of the concrete ridge A. When the start switch 9 is pressed, the front and rear electric motors 6,6 are activated, and the front and rear travel rollers 3,3 are driven and rotated to move forward.

[0018] Apple snails lay a large number of eggs on the side wall of concrete levee A. When the apple snail extermination device 1 moves forward along concrete levee A, the left and right crushing rollers 4,4 come into contact with the side wall of concrete levee A and rotate, crushing the eggs laid on the side wall of concrete levee A. This allows the apple snails to be killed and exterminated before they can enter the field.

[0019] The ultrasonic sensor 10 monitors the forward direction of the apple snail extermination device 1, and when it detects an obstacle in the forward direction, the control device 7 stops the front and rear electric motors 6, 6 to stop the apple snail extermination device 1.

[0020] Then, if the obstacle does not disappear after a predetermined time has elapsed while the control device 7 is stopped, it operates the vertical screw to lower the left and right crushing rollers 4,4 downwards by the height of the crushing rollers 4,4 (the amount by which they are lowered can also be freely set in advance), reverses the front and rear electric motors 6,6 to move the apple snail extermination device 1 in reverse (backward) and returns to the starting position of the work on the concrete levee A and stops.

[0021] The left and right crushing rollers 4,4 may be configured to be driven by an electric motor or the like, or they may be brush-shaped rollers, and the rotation crushes the eggs and peels them off the side wall of the concrete levee A.

[0022] In addition, an ultrasonic sensor for monitoring the reverse direction (backward running direction) may be provided (the ultrasonic sensor 10 may be configured to monitor both the forward direction and the reverse direction), and it may be configured to stop when there is an obstacle in the reverse direction during backward movement.

[0023] In addition, since the eggs of the Japanese apple snail cannot hatch in water, they lay eggs at a slightly elevated position that does not get wet. By peeling off the eggs from the side wall of the concrete ridge A with the left and right crushing rollers 4, 4 and dropping them into the water in the waterway or the field, the eggs of the Japanese apple snail cannot hatch. Therefore, they can be exterminated by being killed before entering the field.

[0024] Since the extermination ability is enhanced when the Japanese apple snail extermination device 1 is operated when there is water, for example, it may be configured to recognize whether there is water in the bulletin of the Japanese apple snail extermination device 1 with an ultrasonic sensor 10 or the like, and if there is water, perform extermination.

[0025] <Other Embodiments> The spread of services for lending and borrowing agricultural machinery through sharing services and rentals has begun to progress, but basically, the specification in units of time (borrowing for several hours to several days) is common. However, even when borrowing for one day, there is no charge variation depending on the area of the field.

[0026] In addition, the sharing service and rental of agricultural machinery have the problem that the farming seasons overlap.

[0027] In addition, theft prevention measures for agricultural machinery are required in sharing services and rentals.

[0028] Therefore, in a map data-linked agricultural machine (for example, an agricultural machine such as a rice transplanter equipped with a control device having map data and GNSS for calculating the vehicle position), it is configured that work (for example, planting work) can only be performed within a range determined by the map data.

[0029] Therefore, by using agricultural machinery (e.g., rice transplanters) that can only perform tasks (e.g., planting) within a field area defined in the map data, it becomes possible to manage operations based on field area through sharing services or rentals.

[0030] Furthermore, management using map data allows for adjustment of the number of units according to the time of year.

[0031] Furthermore, since work (such as planting) cannot be performed outside the designated field area on the map data, it also helps prevent theft.

[0032] Furthermore, when agricultural machinery is reserved through sharing services or rentals, the map data reserved via QR code (registered trademark) is digitized to collect information on farming seasons and areas for each district.

[0033] Therefore, because there are slight differences in farming seasons depending on the region or cultivation method, the number of agricultural machines provided through sharing services or rentals can be adjusted by analyzing the information in the collected map data.

[0034] For example, if it is known that the number of units used for sharing services and rentals in area A will be high from May 10th to 20th, and that in area B the number will be high from May 18th to 23rd, then the number of units can be adjusted by transferring agricultural machinery from area B to area A before May 10th.

[0035] Furthermore, when agricultural machinery leaves the field where it has been reserved through a sharing service or rental, a pop-up message indicating that the operation has stopped (planting unit stopped) is displayed (for example, "The operation unit (planting unit) has been stopped because it has gone outside the field"), and at the same time, a buzzer sounds or an audio alarm is emitted to inform the operator that the machinery has gone outside the field.

[0036] Furthermore, outside of the field where the agricultural machinery has been reserved, even if the work clutch (planting clutch) is engaged, the work clutch does not engage (the planting clutch does not operate to engage).

[0037] Furthermore, while map linkage is active (when the vehicle is equipped with a control device that has map data and a GNSS to calculate its own position), if the vehicle exceeds the predetermined field range, the work clutch (planting clutch) will be disengaged even if the work clutch is engaged (planting clutch is engaged).

[0038] Furthermore, if the system is not linked to the map (i.e., if it is not equipped with a control device that has map data and GNSS to calculate the vehicle's position), the work clutch will not engage even if the planting clutch is engaged.

[0039] Therefore, if you try to work in a field that hasn't been designated in advance, you won't be able to.

[0040] The fees for sharing services and rentals are determined based on the field area read from the map data.

[0041] Therefore, by using a pricing system based on the area worked rather than the time spent, it becomes easier for people who only want to do a little farm work to use the service.

[0042] Furthermore, in rental and sharing services, it is cumbersome for users to set up field information and other details each time they use the service.

[0043] Therefore, the system will be used in rental and sharing services to convert map data, which records the set field shape, fertilizer application rate, etc., into a QR code (registered trademark).

[0044] Therefore, by converting map data that records field shape, fertilizer application settings, etc., into QR code (registered trademark) information, users can immediately use the service by scanning their own QR code (registered trademark) during subsequent rentals or sharing services.

[0045] Agricultural machinery can also be used immediately without any setup hassle by scanning a QR code (registered trademark).

[0046] Furthermore, the system will allow the QR code (registered trademark) to be sent to other devices (smartphones and tablets) in rental and sharing services.

[0047] Therefore, by adding the QR code (registered trademark) to the user's smartphone or tablet, they can use it simply by presenting it the next time they use rental or sharing services.

[0048] Furthermore, a drawback of rental and sharing services is that the usage periods for agricultural machinery can sometimes overlap.

[0049] For example, if "the first person rents agricultural machinery from the store, performs farm work, and returns it to the store. Then the second person rents agricultural machinery from the store, performs farm work, and returns it to the store. Furthermore, the third person rents agricultural machinery from the store, performs farm work, and returns it to the store," then the return process will take time.

[0050] Therefore, in rental and sharing services, a system will be implemented that allows users to make reservations for rental and sharing services by uploading an image of a QR code (registered trademark) to a dedicated website.

[0051] The information from the QR code (registered trademark) allows for the management of reservations based on the location of agricultural machinery.

[0052] For example, if the previous user is working in a nearby location, the first person can rent agricultural machinery from the store, perform farm work, and then the second person can go to the first person's field, rent the machinery, and perform farm work, thus eliminating the need to return the machinery.

[0053] <Other Embodiments> In a diesel engine equipped with an intake throttle valve (ITV) for heating the exhaust gas aftertreatment device (DPF), the DPF is positioned on top of the engine. The ITV is positioned on top of the engine. The ITV is positioned closer to the fan than the DPF. The ITV and the intake manifold are connected by a pipe or hose made of aluminum, resin, or rubber.

[0054] Furthermore, the ITV is positioned at an angle of approximately 45 degrees around the valve shaft. The ITV is positioned closer to the fan than the DPF. The ITV and the intake manifold are connected with pipes or hoses made of aluminum, resin, or rubber. A portion of the piping connecting the ITV and the turbocharger is made of aluminum or resin to reduce costs.

[0055] Furthermore, the intake throttle valve is positioned on the upper side of the engine. The pressure sensor is positioned above the point where the intake passage and the EGR gas passage intersect (upstream of the intake). Because the pressure sensor does not come into direct contact with the EGR gas, it is less likely to become contaminated. This ensures the reliability of the pressure sensor.

[0056] Furthermore, a tone wheel for detecting the crank rotation angle is placed inside the gear case. A balancer to reduce engine vibration is placed under the cylinder block. An opening is provided in the lower part of the gear case and connected to the oil pan. By connecting the lower part of the gear case to the oil pan, oil is less likely to accumulate inside the gear case, minimizing the rise in oil temperature caused by the tone wheel stirring up the oil.

[0057] Furthermore, blow-by gases discharged from the engine are separated into gas and oil within the cylinder head cover and either discharged outside the engine or returned to the engine intake. A key feature is that the baffle plate opening inside the head cover is positioned to prevent rocker arm oil droplets from scattering.

[0058] Furthermore, the rocker shaft assembly is fastened with stud bolts (A) and nuts. The cylinder head cover assembly is fastened with stud bolts (A) and cap nuts. A baffle plate is placed inside the cylinder head cover assembly above the rocker shaft assembly. The blow-by outlet is placed in the space partitioned by the baffle plate. A pressure regulating spring is placed below the diaphragm for regulating the internal pressure of the crankcase.

[0059] Furthermore, a DOC (oxidation catalyst) is placed within the EGR piping. The DOC and EGR cooler are arranged in parallel, and a valve is placed either upstream or downstream of them to allow selection of the direction of exhaust gas flow between EGR and DOC. When forcibly regenerating the DPF, the valve is switched to allow gas to flow towards the DOC, and a portion of the exhaust gas is diverted to the DOC in the EGR piping. The catalytic reaction within the DOC heats the exhaust gas. The heated exhaust gas is returned to the intake air, raising the intake air temperature. The resulting increase in exhaust temperature shortens the DPF light-off time. [Explanation of Symbols]
