When the handle 17 is in the vertical position C, the on-off valve 25 can be opened and closed. valve 25
The tip 34 of the opening/closing valve 25 fits into the groove 16 of the feed roll 10, c. When the handle 17 is in the rear horizontal position B, the tip 34 of the on-off valve 25 is located near the outer periphery of the feed roll 10. This is a spill prevention device for the feeding device.

(Embodiment) An embodiment of the present invention will be described with reference to the drawings. Reference numeral 1 denotes a supply hopper, and a rectangular input port 2 is formed in the upper part.

On the side plates 3, 3 on both the left and right sides of the supply hopper 1,
The upper ends of the side plates serving as the supporting legs 4, 4 are attached, respectively, and a pair of wheels 5, 5 are attached to the front and rear of the lower ends of the supporting legs 4, 4. The wheels 5, 5 fit into the left and right edges 7, 7 of the seedling raising box 6 placed on the open ground.

Sprockets 9, 9 are fixed to the protruding parts of the shafts 8 of the wheels 5, 5, and a chain 13 is connected between the sprockets 9, 9 and a sprocket 12 fixed to the shaft 11 of the feed roll 10 located in the upper intermediate position. wind it.

The feed roll 10 is mounted on a shaft 11 at the lower end of the supply hopper 1 . 15 is a feeding port.

A plurality of grooves 16 are formed in the outer peripheral surface of the feed roll 10 in the generatrix direction, and the feed roll 10 is formed to rotate only when the supply hopper 1 is moved forward.

A lower end portion of a handle 17 is pivotally attached to an upper position in the front and back center of the supply hopper 1 by a shaft 18. The handle 17 is formed into a mold shape when viewed from the front and rear sides.

In FIG. 2, the handle 17 is approximately centered on the axis 18 between position A when the front side is laid down and position B when the rear side is tilted sideways.
It can be rotated 180°. The handle 17 is extended further downward from the portion pivoted by the shaft 18 to form an extension 19, and the upper end of a rod 20 is pivoted to the lower end of the extension 19 by a pin 21.

Reference numeral 22 denotes an arm, and the center portion of the arm 22 is pivoted to the side plates 3, 3 via a shaft 23. The shaft 23 is located at a lower position in front of the shaft 18 to which the handle 17 is attached. The lower end of the rod 20 is pivoted to one end of the arm 22 by a pin 24.

An on-off valve 25 is provided near the front side of the feed roll 10. When the on-off valve 25 is viewed from the side,
The upper inclined plate 26 and the lower inclined plate 27 form a dogleg shape. The lower end of the lower inclined plate 27 is fixed to a shaft 28 parallel to the shaft 11 of the feed roll 10, and both ends of the shaft 28 are rotatably fixed to the support legs 4, 4.

The lower end of an arm 29 is fixed to both left and right positions of the lower end of the upper inclined plate 26, and the upper end of the arm 29 and the other end of the arm 22 are pivotally fixed by a connecting rod 30. Therefore, when the handle 17 is rotated, the on-off valve 25 is rotated about the shaft 28.

This rotation of the on-off valve 25 is such that when the handle 17 is in the front sideways position A, the tip 34 of the on-off valve 25 is separated from the outer peripheral surface of the feed roll 10 to the maximum (FIG. 3), and the supply hopper 1 The seed rice, etc. inside is fed out through the outlet 15.
This is the supply position where it is fed out more.

When the handle 17 is in the vertical position C, the on-off valve 2
The tip 34 of the feed roll 1 fits into the groove 16 of the feed roll 10 and closes the feed opening 15.
The rotation of 0 is completely stopped and the spill prevention position is reached (Figure 4).

When the handle 17 is in the rear horizontal position B, the on-off valve 2
The distal end 34 of the on-off valve 25 closes the dispensing port 15 to prevent spillage, but the distal end 34 of the on-off valve 25 closes the dispensing roll 1
The position is such that it does not fit into the groove 16 of No. 0 (FIG. 5).

31 is a brush that contacts the outer peripheral surface of the delivery roll 10, 32 is a delivery amount adjustment device, and 33 is a sieve screen for sieving the covered soil.

(effect) Next, we will discuss the effect.

(Function of the vertical position C of the handle 17) After putting the seed rice into the supply hopper 1, the handle 17
Lift up the supply hopper 1 by holding the handle 17.
rotates about the shaft 18 and assumes the vertical position C as shown in FIG. The extension 19 of the handle 17 becomes vertical and pushes the rod 20 downward, causing the lower end of the rod 20 to pivot the arm 22 about the axis 23 in the direction of arrow D. Since the upper end of the connecting rod 30 is pivotally attached to the other end of the arm 22, the connecting rod 30 is pulled up by the other end of the arm 22, and the arm 2, which is pivotally attached to the lower end of the connecting rod 30, is pulled up by the other end of the arm 22.
Pull 9 upward. Since the lower end of the arm 29 is fixed to the lower end of the upper inclined plate 26 of the on-off valve 25, the on-off valve 25 is rotated about the shaft 28 in the direction of arrow H, and the tip of the upper inclined plate 26 of the on-off valve 25 is rotated. 3
4 fits into the groove 16 of the feed roll 10 to close the feed opening 15 and fix the feed roll 10. Therefore, even if the device is carried by holding the handle 17, the seeds and mud in the supply hopper 1 will not spill out.

(Function of the A position of the handle 17) Then, the seedling raising box 6 is placed in the open ground, the wheels 5 are aligned with the edge 7 of the seedling raising box 6, and the handle 17 is rotated to the A position. The extension 19 of the handle 17 pivots in the opposite direction, pulling the rod 20 and causing one end of the arm 22 to move upward and pivot about the shaft 23.
The other end of the arm 22 is moved downward, the connecting rod 30 is moved downward, and the on-off valve 25 is rotated in the opposite direction of the arrow. Separated from the groove 16, the outlet 1
5 is released.

Therefore, when the device is ready for sowing and covering with soil, the wheel 5 placed on the edge 7 of the seedling box 6 rotates, and the sprocket 9 fixed to the shaft 8 of the wheel 5 rotates. , the feed roll 10 is rotated via the chain 13, and the seed rice, soil, etc. are fed out from the feed port 15.

(Function of the handle 17 in the B position) Used when returning the device to its original position. This device is
Push it to the other side to sow and cover soil, then pull it to the front to prepare for the next task.

When the handle 17 is rotated to the rear horizontal position B, the extension part 19 is in the position shown by the dotted line in Figure 2, and the rod 20
The arm 22 is slightly rotated through the opening/closing valve 2.
The tip 34 of 5 is located close to the outer peripheral surface of the feed roll 10.

If you pull this device toward you in this state, the feed roll 10 will not rotate, so it will not leak, but since the gap is also closed, leakage will be prevented.
You can restore it as above.

(Effects) The problem with the known method is that the tip of the on-off valve has only two stages: either it fits into the groove of the delivery roll, or it separates. In the known example, after sowing by pushing, the tip of the on-off valve is retracted with the tip of the feed roll fitted into the groove of the feed roll, so if the clutch does not release even when the clutch is released, the most important feed roll Damage to the grooves of the roll.

However, the present invention has a supply hopper 1 and seedling growing boxes 6 provided on both left and right sides of the lower part of the supply hopper 1.
A pair of left and right wheels 5 that fit on the left and right side edges 7 of the wheel 5, a sprocket 9 fixed to the shaft 8 of the wheels 5, and a groove 16 in the generatrix direction on the outer peripheral surface provided at the outlet 15 of the supply hopper 1. and an on-off valve 2 whose lower part is fixed by a shaft 28 and whose upper tip 34 is rotatable in a distance relative to the feed roll 10.
5, a sprocket 12 that is fixed to the feed roll 10 and transmits rotation only when the machine moves forward; a chain 13 wound around the sprocket 9 and the sprocket 12; A handle 17 that rotates between a front horizontal position A, a vertical position C, and a rear side horizontal position B, an extension part 19 extending downward from the pivoting part of the handle 17, and the extension part 19. a rod 20 having one end engaged with the rod 20, an arm 22 having one end engaged with the other end of the rod 20 and having its center pivoted to a fixed part; and a connecting rod 30 that engages one end of the arm 29, and the other end of the connecting rod 30 is fixed to the middle part of the on-off valve 25 to connect the handle 17 and the on-off valve 25. When the handle 17 is in the vertical position C, the tip 34 of the on-off valve 25 is spaced apart from the outer peripheral surface of the delivery roll 10 when the handle 17 is in the vertical position C.
The tip 34 of the opening/closing valve 25 fits into the groove 16 of the feed roll 10, c. When the handle 17 is in the rear horizontal position B, the tip 34 of the on-off valve 25 is located near the outer periphery of the feed roll 10. Since this is a spill prevention device for the feeding device, it is different from known examples and has a three-stage switching mechanism, so even if the clutch does not come off when pulling this device, the groove 16 will not be damaged and the seeds will not be damaged.・Completely prevent soil leakage. In addition, three-stage switching is possible with a simple configuration.
