Description

[Detailed description of the invention] This invention is a device for planting bulbs, etc. that is attached to the rear of a self-propelled agricultural machine and is towed. A large number of receptacles are installed in close proximity to the hopper, and are arranged in parallel on a conveyor belt that is wound around a main drive pulley that rotates using the rotational force that rotates on its own axis due to resistance, and a driven pulley that is provided to follow the drive pulley. By passing through the opening provided in the vertical pipe and the bottom of the hopper, and rotating upward from the bottom side along the inner wall surface of the hopper, the bulb rises while scooping up the bulbs, etc. inside the hopper, and when it reaches the top. Then, as it descends inside the vertical pipe, the receiving surface of the container faces downward, and the bulbs, etc. on the container fall onto the back of the container in the previous position, and the inside of the vertical pipe is clamped to the edge of the container. This causes the bulb to fall to the release position at the lower end of the vertical tube while rubbing against the inner surface of the vertical tube, causing damage to the bulb and the like. Therefore, scooping containers each having a concave surface in the direction of rotation are provided with receptor portions each having a concave surface in the opposite direction on the back side, and are arranged in parallel on the conveyor belt at a predetermined interval in the required number of sets to lower the container. Bulbs, etc. that fall from the scooping container that is in the posture are caught on the upward facing receptor part in the preceding position, and descend without damaging the bulbs, etc., to the throwing position at the lower end of the vertical tube, without touching the inner surface of the vertical tube. Therefore, it is an object of the present invention to provide a conveyance device for a planter for planting bulbs, etc., which can eliminate the above-mentioned problems.

To explain the embodiment with reference to the drawings, reference numeral 1 denotes a machine frame equipped with each member constituting the planter for planting bulbs and the like. Reference numeral 2 denotes a connecting rod that is inserted into a connecting portion (not shown) provided at the rear end of the agricultural power self-propelled machine and is towed. 3 and 3' are pillars whose lower ends are fixed to the machine frame 1 and stand up parallel to each other.
A pulley 4 is pivotally supported at its upper end. 5
is supported behind the supports 3 and 3' by a hopper for loading bulbs and the like. 6 and 6' are rotation shafts 7 rotatably mounted on the machine frame 1 and arranged at right angles to the traction direction.
The rolling wheels are fixed to both the left and right ends of the wheel, and 6'' is a lug placed on the outer periphery of each wheel.A pulley 8 is fixed at the center of the rotating shaft 7, and the rotation of the rolling wheels 6, 6' is controlled by a pulley 8. 9 is a conveyor belt that is wound around the pulleys 4 and 8, passing through an opening 10 provided at the bottom of the hopper 5 and along the inner wall of the hopper 5. 11 is an example of the container of the present invention. It consists of a scooping container 12 on the side for scooping up bulbs, etc. and a receptor part 13 assembled to this in a back-to-back state, that is, the back side of the scooping container 12 having a concave surface in the direction of rotation. are provided with receptors 13 having concave surfaces facing in opposite directions, and a large number of sets of these are arranged side by side at equal intervals around the outer periphery of the conveyor belt 9.The scooping container 12 and the receptor part 13 each have a swinging bulb or the like. It has a dent that is large enough to prevent it from falling.
a (dotted oval) exemplifies a bulb. 14 is a vertical pipe whose upper end is supported on mounting parts 5' and 5'' extending forward of the upper edge of the hopper 5, and whose lower part is supported on the machine frame 1, and which is covered closely so that the container 11 can pass through. The lower end extends to a position where it is included in a groove cutting plate 15 that cuts a planting groove arranged in front of the lower end,
It also serves as a guide to prevent the bulb a from popping out when it descends, and has an opening 18 at its end. 1
Reference numeral 6 denotes a support rod fixed vertically to the front part of the groove cutting plate 15, which is positioned in front of the vertical pipe 14 and is fitted into a through fitting 17 fixed to the machine frame 1, so that the support rod 6 is fixed to the front part of the groove cutting plate 15 in the vertical direction. It is fixed and can be adjusted vertically.

Next, to explain the operation, when the planting machine is connected to the rear end of the self-propelled agricultural machine and is being towed, the rolling wheels 6, 6' touch the ground while being prevented from slipping by the lugs 6''. When it rolls due to resistance, the rotating shaft 7
The pulley 8 fixedly attached to the pulley 8 rotates, the conveyor belt 9 wound around the pulley 8 and the pulley 4 is rotated, and the containers 11 arranged in parallel to the conveyor belt 9 are rotated.
The material passing through the hopper 5 rises and the vertical pipe 14
Anything that passes through it rotates in a downward motion. Therefore, the scooping container 12 on the scooping side of the container 11 scoops up the bulbs (not shown) loaded in the hopper 5 as shown in FIG. When the bulb a passes the upper part and reaches the position where it begins to descend, it falls away from the scooping receptacle 12, is received by the receiving receptacle part 13 which is descending at the preceding position, and is placed in the recess while being vertically moved. The receptor part 13 wraps around and tilts under the pulley 8 without being pinched between the tube 14 and the receptor part 13 and is safely carried down to the point where it falls off the receptor part 13. Vertical pipe 1
4 falls into the planting groove cut by the groove cutting plate 15. Therefore, bulb a
Since the bulbs do not rub against the vertical pipe 14 while descending, the bulbs are not damaged and unnecessary mechanical power is not required, eliminating slips on the conveyor belt and allowing smooth planting work. This is particularly effective as a planting machine for the delicate seedlings of Konniyaku. Furthermore, since the falling posture of the bulbs is almost constant, the intervals at which the bulbs fall to the ground can be made to be approximately equal.

This invention passes through a vertical pipe provided close to the hopper and an opening provided at the bottom of the hopper, and is wound around the upper and lower pulleys so as to rotate upward from the bottom of the hopper along the inner wall surface of the hopper. The conveyor belt is equipped with a receiving part with an opposite concave surface on the back side of the scooping container, which has a concave surface, so that the bulbs are completely received by the receiving part and descend, so that the bulbs can be easily transported inside the machine. Since the bulbs and spores will not be caught between the container and the inner wall surface of the vertical tube, which is the most susceptible to damage, friction during descent will not occur.
No damage to the bulbs or seedlings will occur, the falling intervals are approximately equal, no unnecessary power is required, and there are effects such as the elimination of slips on the conveyor belt.
