[0015] Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.

[0016] A transplanter according to an embodiment of the present invention will be described below with reference to Figures 1 and 2. In the following description, the side on which the operating handle 2 is located will be referred to as the rear, and the opposite side will be referred to as the front. The right hand side facing the front of the machine body will be referred to as the right, and the left hand side will be referred to as the left.

[0017] This transplanter is equipped with a running body 1 that enables the machine to travel forward and backward, a steering handle 2 for pedestrian operation provided at the rear of the running body 1, a ridge forming device 20 for cultivating and forming ridges in the field, and a seedling planting device 30 for planting seedlings in the field.

[0018] The running body 1 has left and right drive wheels 4 as running devices on the left and right sides of a transmission case 3 located in the front-to-rear center, a battery case 6 containing a battery 6a mounted on the upper part of a rear frame 5 mounted at the rear of the transmission case 3, a first cover 7 containing a first motor 7a for running and tilling mounted on the upper part of the transmission case 3, a second cover 9 containing a second motor 9a for planting seedlings mounted on the upper part of a front frame 8 mounted at the front of the transmission case 3, the front part of a ridge forming device 20 mounted on the lower part of the front frame 8, and a seedling planting device 30 mounted on a hitch 10 at the front of the front frame 8.

[0019] A first motor 7a for traveling and cultivating housed in the first cover 7 and a second motor 9a for planting seedlings housed in the second cover 9 are driven by power from a battery 6a housed in the battery case 6.

[0020] A chain case 11 is provided between the drive shaft 7b of the first motor 7a and the input shaft 3a of the transmission case 3, and the driving force of the first motor 7a is transmitted to the transmission case 3 by the chain case 11, and the power is transmitted to the left and right drive wheels 4 and the ridge forming device 20 via a transmission device inside the transmission case 3.

[0021] The driving force of the second motor 9a is transmitted to the seedling planting device 30 via a drive shaft 9b.

[0022] The control handle 2 has its base fixed to both the left and right sides of the first cover 7, extends toward the rear of the aircraft, and has left and right grips 2a at its rear end.

[0023] Therefore, since the control handle 2 is provided with its base fixed to the first cover 7 that houses the first motor 7a, the first cover 7 can also serve as a support frame for the control handle 2, resulting in a simple configuration.

[0024] In addition, a control panel 25 for operating and setting each part of the aircraft is provided on the connecting stay 2b that connects the rear part of the steering handle 2.

[0025] The ridge forming device 20 comprises a number of tillage tines 22 attached to a tillage shaft 21 which rotates by driving force from a transmission case 3, and a tillage cover 23 which covers the tillage tines 22, and is provided at the rear of the tillage cover 23 with a conventional ridge former 24 which forms kamaboko-shaped ridges.

[0026] In addition, a pressing roll for pressing down the upper surface of the ridge may be provided at the rear of the ridge forming device 20.

[0027] The seedling planting device 30 comprises a beak-shaped seedling planting body 31 with its tip facing downward, a vertical movement mechanism for moving the seedling planting body 31 up and down between a position where the lower end of the seedling planting body 31 is above the field surface and a position where it is below the field surface, an opening / closing mechanism for opening and closing the seedling planting body 31 between a closed state where the lower end of the beak-shaped seedling planting body 31 is closed to receive seedlings from above and store the seedlings inside, and an open state where the lower end of the seedling planting body 31 opens to the left and right and the seedlings stored inside can be released downward, a seedling supplying device 40 for supplying one seedling to the seedling planting body 31, and a soil covering and compacting device 50 for covering the seedlings planted in the field (ridges) with soil and compacting the left and right sides.

[0028] The seedling planting body 31 is attached to a vertical movement mechanism provided on the right side of a planting transmission case provided on the main frame of the seedling planting device 30. The driving force of the second motor 9a is transmitted to the planting transmission case through a drive shaft 9b.

[0029] The vertical movement mechanism is equipped with upper and lower lifting links, the front of which is attached to the planting transmission case so as to be freely rotatable up and down, and the rear of which is connected to the seedling planting body 31. A separately provided drive mechanism uses power from inside the planting transmission case to move the upper and lower lifting links up and down, causing the seedling planting body 31 to move up and down. In the raised position, the lower end of the seedling planting body 31 is located above the field surface, and in the lowered position, the lower end of the seedling planting body 31 is located below the field surface (top of the ridge).

[0030] The opening and closing mechanism for the seedling planting body 31 is operated by power from inside the planting transmission case, and is linked to the operation of the up and down movement mechanism so that when the seedling planting body 31 reaches the lowermost position, the lower side of the seedling planting body 31 opens to the left and right to be in an open state downward, and when the seedling planting body 31 reaches the uppermost position of the rise, the lower side of the seedling planting body 31 closes to be in a closed state.

[0031] In addition, a planting cover 32 is provided around the planting transmission case and the seedling planting body 31.

[0032] The seedling supply device 40 includes a plurality of seedling containers 41 that receive seedlings from above and store them inside, a moving mechanism that moves the seedling containers 41 in a circular motion so as to pass above the seedling planting body 31, and an opening mechanism that serves as a seedling drop supply mechanism that opens the bottom of the seedling container 41 above the seedling planting body 31 to drop the seedlings stored inside and supply the seedlings to the seedling planting body 31.

[0033] The seedling supply device 40 comprises a plurality of seedling containers 41, each having a cylindrical body that opens at the top and bottom and a bottom lid that opens and closes the lower opening of the cylindrical body, which are connected to each other in a loop like an endless chain, a moving mechanism that moves the seedling containers 41 in a counterclockwise direction in a long oval loop-shaped trajectory in the front and rear of the body when viewed from the top, while passing near the top of the seedling planting body 31, an opening mechanism that opens the bottom lids of the seedling containers 41 above the seedling planting body 31, and a flat plate that serves as a cover body to guide and cover the inner periphery of the plurality of seedling containers 41 connected in a loop shape.

[0034] The opening mechanism of the seedling supplying device 40 is configured such that a support is provided to support the bottom cover from below so that the bottom cover does not rotate downward below the orbit of the seedling container 41, and this support is not provided above the seedling planting body 31, so that when the seedling container 41 passes above the seedling planting body 31, the bottom cover is released from the support and rotates downward, allowing the seedlings in the seedling container 41 to fall downward. The timing at which the bottom cover of the seedling container 41 opens is adjusted so that it occurs when the seedling planting body 31 rises to just below the seedling container 41.

[0035] The moving mechanism of the seedling supplying device 40 is operated by power from within the planting transmission case.

[0036] The soil covering and compacting device 50 has left and right compacting wheels 51 which compact and cover the left and right sides of the seedlings planted in the field (ridges) by the seedling planting body 31. The left and right compacting wheels 51 are rotatably supported at both left and right ends of a balance rod 52 which moves up and down a predetermined amount in an opposing manner, and the balance rod 52 is supported at the lower end of a support frame 53 whose base is attached to the front end of the main frame of the seedling planting device 30 so that it can be freely adjusted up and down.

[0037] The control panel 25 located between the rear parts of the steering handlebars 2 is provided with a main switch operation unit, a linked acceleration / deceleration operation unit which accelerates / decelerates the first motor 7a and the second motor 9a in conjunction with each other, a first acceleration / deceleration operation unit which rotates the first motor 7a in forward / reverse directions and accelerates / decelerates the first motor 7a, a second acceleration / deceleration operation unit which accelerates / decelerates and stops the second motor 9a, a ridge-forming clutch operation unit which engages and disengages the ridge-forming clutch of the drive system to the ridge-forming device 20 in the transmission case 3, a left side clutch operation unit which engages and disengages the left side clutch of the drive system to the left driving wheel 4 in the transmission case 3, a right side clutch operation unit which engages and disengages the right side clutch of the drive system to the right driving wheel 4 in the transmission case 3, a driving stop operation unit which engages and disengages the left and right side clutches of the drive system to the left and right driving wheels 4 in the transmission case 3, and a monitor which displays information about each unit, such as the operating status of the first motor 7a and the second motor 9a.

[0038] By combining the setting of the travel speed using the first acceleration / deceleration control unit and the setting of the planting speed using the second acceleration / deceleration control unit, precise spacing between plants can be set.

[0039] A recess 7c is formed on the upper surface of the first cover 7, which houses the first motor 7a for traveling and tilling, so that a large number of seedlings supplied by the operator can be placed inside the seedling storage body 41 of the seedling supplying device 40.

[0040] In addition, a recess in which a large number of seedlings supplied by an operator are placed in the seedling container 41 of the seedling supplying device 40 may be provided in the battery case 6 or in the upper part of the second cover 9.

[0041] When the transplanter is to travel on inter-field roads or ridges, the main switch is turned on using the main switch operation unit, the second motor 9a is stopped using the second acceleration / deceleration operation unit to stop the seedling planting device 30, the ridge-making clutch to the ridge-making device 20 is disengaged using the ridge-making clutch operation unit, the first motor 7a is operated to move the machine forward or backward using the first acceleration / deceleration operation unit, and the operator grips the left and right gripping portions 2a at the rear end of the steering handle 2 and pushes down on the rear of the machine so as to lift the front of the machine, while moving the machine forward or backward.

[0042] When transplanting work is performed in the field, the main switch is turned on using the main switch operation unit, the second motor 9a is set to a predetermined speed using the second acceleration / deceleration operation unit to operate the seedling planting device 30 at the predetermined speed, the ridge-making clutch to the ridge-making device 20 is engaged using the ridge-making clutch operation unit, and the first motor 7a is operated to the reverse side of the machine at a predetermined speed using the first acceleration / deceleration operation unit to move the machine backwards at a slow speed, and the seedlings are transplanted using the seedling planting device 30 onto the top surface of the ridges where tilling and ridge making work has been performed using the ridge-making device 20.The worker walks on either the left or right side of the machine as it moves backwards, removing the seedlings placed in the recess 7c on the upper surface of the first cover 7 one by one and placing them into the seedling container 41 of the seedling supply device 40, and the seedlings are transplanted onto the top surface of the ridge by the seedling planting body 31, and both the left and right sides of the seedlings are compacted and covered with soil by the soil covering device 50.

[0043] It should be noted that if the second motor 9a is stopped by the second accelerating / decelerating operation unit and the first motor 7a is operated by the first accelerating / decelerating operation unit, only the ridge forming work can be performed.

[0044] In addition, by operating the first motor 7a using the first acceleration / deceleration operation unit, operating the second motor 9a using the second acceleration / deceleration operation unit, and disengaging the ridge-forming clutch to the ridge-forming device 20 using the ridge-forming clutch operation unit, only seedling transplanting work can be performed.

[0045] In summary, the machine body has a traveling device 4 that is operated by driving force from the transmission case 3, and is equipped with the ridge making device 20 and the seedling planting device 30, so that ridge making work and seedling transplanting work can be performed simultaneously, shortening work time and reducing labor.

[0046] Furthermore, by providing the transplanter with the first motor 7a for driving the ridge forming device 20 and the second motor 9a for driving the seedling planting device 30, added value can be improved by electrification. [Explanation of symbols]
