Description

[Detailed description of the invention] This invention relates to an anther collecting machine, and its purpose is to collect anthers from flowers of fruit trees such as pears that require artificial pollination in a suitable and efficient manner without damaging the anthers. The goal is to provide an anther harvesting machine that can do this.

Generally, as shown in Figure 1A, a flower such as a fruit tree has petals 2 attached to a calyx 1, a pistil 3 in the center surrounded by the petals 2, and a stamen 4 attached to surround the pistil 3. There is.

This stamen 4 consists of anthers 4a and flower feet 4b,
It is necessary to collect only this anther 4a for use in artificial pollination of fruit trees.

However, as shown in Figure 1A, anther 4a and calyx 1,
Since it is surrounded by petals 2 and attached above the flower foot 4b, as shown in Figure 1B, the flowers are first separated by 1, 2,
It is necessary to disassemble the flower into stamens 4 and pistils 3, and then separate the anthers 4a and flower feet 4b as shown in FIG. 1C.

This invention relates to an anther collecting device that can effectively separate the anthers 4a and flower legs 4b, and one embodiment of this invention will be described below with reference to the drawings.

In FIG. 1D, 5 is a base frame, and 5a is the upper frame of this base frame 5. This upper frame 5a is inclined by _θ1 about 10 to 20 degrees. This θ ₁ and θ ₂ described below do not necessarily have to be the same.

6 is a gear pivotally attached to the side of this upper frame 5a,
7 is a sieve, and 8 is a shaft attached to the lower end of the sieve 7 and loosely fitted into and removed from the gear 6.

9 is a hopper, and 10 is a guide plate.

11 is a belt conveyor, and 12 is a roller that drives this belt conveyor 11.

In addition, 13 is a receiving material. This belt conveyor 11 is inclined by _θ2 of about 10 to 30 degrees.

As shown in FIG. 2, at least one of the rollers 12 is provided with a required number of side strips 14 on the outer periphery thereof, which bulge at the center of the roller.

In FIG. 3, 15 is a drive source such as a motor, 16 is a drive belt that connects the motor 15 and the roller 12, and 17 is a drive belt that connects and drives the motor 15 and the gear 6.

The anther harvesting machine according to the embodiment of this invention having such a configuration first supplies petals 2, stamens 4, and calyx 1 in a separated state from above the hopper 9, and
These components to be separated are fed onto a sieve 7, which is mounted at the required angle of inclination θ ₁ and in addition to the components supplied with vibration by the operation of the drive and vibration device, the gear 6 and the shaft 8; The petals 2 and calyx 1 and other coarse particles do not pass through the sieve 7 and fall downward from the sieve 7 along the inclination θ ₁ , and the stamens 4 separated into petals 4 b and anthers 4 a are guided to the guide plate 10 . and falls onto the belt conveyor 11.

When passing through the sieve 7, the anthers 4a and the petals 4b are separated by vibration caused by the loose fitting and unfitting of the shaft 8 into the gear 6 and fall onto a belt conveyor 11 having an inclination angle θ ₂ .

In this state, the anthers 4a, which have a light specific gravity, fall into the receiving material 13 while rising on the belt conveyor 11, while the flower feet 4b, which have a relatively heavy specific gravity, fall below the belt conveyor 11. This effect may not function fully depending on the setting of the inclination angle θ ₂ .
~30°.

In this manner, the anthers 4a and the flower legs 4b are separated by the operation of the belt conveyor 11, and only the anthers 4a can be suitably collected.

As shown in FIG. 4, when the roller 12 is cylindrical, the conveyor belt 12c suspended between the rollers 12 and 12 often comes off the roller 12, but in the embodiment of this invention, , a required number of side members 14 that bulge at the center are attached to the outer periphery of the roller 12, so that this conveyor belt 12c always applies tension to the conveyor belt 12c.
to keep the conveyor belt 12c suspended in the correct position between the rollers 12, 12.

In the embodiment of this invention, the side strips 14 have a shape that bulges at the center of the roller in FIG. 2, but it is not necessary to limit the side strips 14 to this shape. Any side member 14 can be preferably used as long as it is a member having a desired shape to be attached and has a shape that applies at least tension to the conveyor belt 12c.

Further, as shown in FIG. 1D, the mechanism for vibrating the sieve 7 can be achieved by installing a driving gear 6 on at least one end of the sieve 7 and a shaft 8 that loosely fits into and disengages from the gear 6. In this invention, it is also possible to change the other structure to, for example, an elastic thread 18 instead of the gear 6 and shaft 8 structure.

As described in detail above, the anther collecting machine according to an embodiment of the present invention has an upper frame of the base frame inclined at a required angle of inclination θ ₁ , a gear pivotally attached to the side of the upper frame, and a trough of the gear. A sieve placed on the upper frame through a shaft loosely fitted into the sieve, through which the anthers and flower feet can pass, and a sieve below the sieve with an inclination angle θ ₂ of about 10 to 30 degrees to the base frame. This belt conveyor is driven in the upward direction, and at least one of the rollers of this belt conveyor has a required number of side strips attached to its outer periphery. The conveyor belt is correctly suspended between the rollers, and in this state the device is driven to first separate each component of the pre-separated flowers using a sieve without damaging the anthers, and then separate the flower legs and anthers using the belt conveyor. This is an anther collecting machine that has the effect of being able to accurately collect only the anthers.
